Definition Of China Mechanical Parts

October 12, 2019 by xinghui  

What is the definition of Chinese mechanical parts? Which are China Mechanical Parts? What are the corresponding castings and forgings?
The definition of Chinese mechanical parts is:
1, parts -- a single component that cannot be split.
2, the component - the combination of parts to achieve an action (or: function). The part can be a part or a combination of multiple parts. In this combination, one part is the main one, it realizes the specified action (or: function), and other parts only play the auxiliary role of connection, fastening, guiding and so on.
3, parts - under normal circumstances, all parts and components except the rack are collectively referred to as parts. Of course, the rack is also a component.
As for casting parts and forging parts, it is a classification of parts manufacturing methods. Different materials and manufacturing methods give parts different mechanical properties. Not the same concept as parts.
Then how to draw the drawings of Chinese mechanical parts
As long as the CAD is simple, a mechanical part usually draws three figures on a piece of paper: the main view (the picture seen from the front of the part), the front view (the picture seen directly from the top of the part), the left view (picture seen from the left side of the part). Generally, the three parts of the simple drawing can be clearly expressed, like a gear shaft. A complicated structure, but also a cross-sectional view and a partial enlarged view, is to cut a part of the part and express its internal structure and dimensions, such as screw holes, gear boxes, gears, and the like. It is not enough to know so much. If you want to know in detail how to paint, you should also look at the mechanical parts drawing. In fact, most of the actual use of assembly drawings, there are many details to pay attention to, practice more, then read the book Ok.
In addition, mechanical parts also have their own standardized production. This is the standardization of mechanical parts in the United States, such as the length and diameter of the screws, etc. A series of parts have been unified standards, so that the machine is very easy to malfunction. repair. This measure is similar to the Chinese Qin Shihuang's unified text, language, and weights and measures!
Finally, the cleaning of Chinese mechanical parts.
The dirt of mechanical parts mainly consists of grease, rust-proof grease and other mixture of sludge. It can be cleaned with alkaline cleaning solution, electrochemically cleaned, or cleaned with ultrasonic cleaner. Ultrasonic cleaning is a special category for cleaning. It belongs to industrial cleaning. Wash with alkaline cleaning solution. The chemical cleaning process of alkaline cleaning solution is: hanging-alkali cleaning-washing (50-900C hot water)-drying (cleaning hot compressed air is blown dry, requires strict parts, dried by compressed air, It also needs to be baked in an electric blast drying oven of 105-1150C for 10 minutes. The electrochemical cleaning of alkaline solution with alkaline cleaning solution should pay attention to the following points: it is not suitable to clean the surface of the machine with thick oil, oil pollution When thick, it needs to be pre-cleaned by other methods; general steel parts should be cleaned on the cathode and then cleaned on the anode. For spring parts, thin-walled steel parts, ultra-high-strength steel parts can not be cleaned on the cathode (to avoid hydrogen permeation of materials, Produces hydrogen embrittlement); parts made of materials such as copper, zinc, nickel, etc. cannot be cleaned on the anode (avoid oxidation of the surface of the material); quantitative analysis of the electrolyte is performed periodically, and the drug is supplemented according to the analysis result.

Principles For The Processing Of China Mechanical Parts

September 29, 2019 by xinghui  

The production of China Mechanical Parts is a material forming technology, and it is a new metal cold deformation processing method that has emerged in recent years. It is one of the main methods of metal plastic processing. In the production of mechanical parts in China, people use the power of traditional or special stamping equipment to punch, use the pressure to deform the material, and then use the metal plate in the mold to deform the parts with certain dimensions. Therefore, Chinese mechanical parts manufacturers in production, need to pay attention to what problems, let the following professional manufacturers for us to introduce!

In the production of mechanical parts in China, it should be noted that engineering equipment such as presses or molds should be used under normal use conditions. This effectively prevents the strip from being transported along the correct location or by our pre-booked gap. We, ah, make sure all parts are tight. In the production of mechanical parts in China, do not change the installation position of the stamping die. Once they change, they scratch or crush the surface of the workpiece. In this way, the quality of the workpiece is greatly affected.

 

Another point is that in the preparation of raw materials, technical specifications must be observed, accurate measurement of raw material particle size, strict inspection of raw materials and card inspection. At the same time, in the production of mechanical parts in China, it is necessary to inspect the grinding tools and some punches carefully and regularly to prevent the wear of the work pieces and guides caused by long-term operation. Strictly observe all relevant precautions when manufacturing Chinese mechanical parts to avoid unnecessary losses.

A Brief Introduction China Mechanical Parts

September 23, 2019 by xinghui  

Mechanical parts are non-detachable basic units that make up the machine, such as bolts, screws, keys, belts, gears, shafts, springs, pins, and so on. China Mechanical Parts are divided into general parts and special parts. A general-purpose part is a part that can be widely used in various machines, and a dedicated part is a part that can be used only in a specific type of machine.

1. Common materials for Chinese mechanical parts

The materials of Chinese mechanical parts are metal materials, non-metal materials and composite materials.

Metal materials are classified into ferrous materials and non-ferrous materials. The ferrous materials include various steels, cast steels and cast irons, which have good mechanical properties (such as strength, ductility, toughness, etc.), are relatively inexpensive and readily available, and can meet a variety of performance and application requirements. Among all kinds of ferrous metals, alloy steels are often used to make important parts because of their excellent properties. Non-ferrous metal materials, including copper alloys, aluminum alloys, bearing alloys, etc., have the advantages of low density, good thermal conductivity and good electrical conductivity, and are usually used in applications where friction, wear and corrosion resistance are required.

Non-metallic materials refer to polymer materials such as plastics, rubber, synthetic fibers, and ceramics. Polymer materials have many advantages, such as abundant raw materials, low density, good elasticity in a suitable temperature range, and good corrosion resistance. The main disadvantage is that it is easy to age, and many of them have poor flame retardancy. In general, heat resistance is not good. The main characteristics of ceramic materials are extremely high hardness, wear resistance, corrosion resistance, high melting point, high stiffness and low density than steel. At present, ceramic materials have been used in structures such as seals, rolling bearings and cutting tools. Its main disadvantages are relatively brittle, low fracture toughness, high price, and poor processing technology.

 

Composite material refers to a new type of material obtained by a composite process using two or more materials having significantly different physical and mechanical properties to obtain the desired properties. For example, non-metallic materials such as glass, graphite (carbon), boron, plastic, etc. can be composited into various fiber reinforced composite materials. The plastic composite steel plate with high strength and corrosion resistance can be obtained by attaching plastic to the surface of ordinary carbon steel plate. The main advantage is that it has high strength and elastic modulus, but the quality is extremely small, but also has poor heat resistance and heat conduction. The disadvantage of poor electrical conductivity. In addition, the price of composite materials is relatively expensive. Therefore, composite materials are mainly used in high-tech fields such as aviation and aerospace. In civil products, composite materials also have some applications.

Metal Stamping Parts Can Not Only be Stamped But Also Cast

September 10, 2019 by xinghui  

Metal Stamping Parts (XINGHUI) machines may do more than just stamping; they can cast, punch, cut and shape metal sheets. Machines can be programmed or computer numerically controlled to offer high precision and repeatability for each stamped piece. Electrical discharge machining and computer-aided design programs ensure accuracy. Various tooling machines for the dies used in the stampings are available. Progressive, forming, compound, and carbide tooling perform specific stamping needs. Progressive dies can be used to create multiple pieces on a single piece simultaneously.

Coining is a bending technique wherein the workpiece is stamped while placed between a die and the punch or press. This action causes the punch tip to penetrate the metal and results in accurate, repeatable bends. The deep penetration also relieves internal stresses in the metal workpiece, resulting in no spring back effects.

Bending refers to the general technique of forming metal into desired shapes such as L, U, or V-shaped profiles. The bending process for metal results in a plastic deformation which stresses above the yield point but below the tensile strength. Bending typically occurs around a single axis. Flanging is a process of introducing a flare or flange onto a metal workpiece through the use of dies, presses, or specialized flanging machinery.

How Does Plastic Injection Parts Work?

September 3, 2019 by xinghui  

Plastic Injection Parts (XINGHUI) molds must have a high precision match between the two mold halves in order to perfectly control the material flow. Creating the mold is crucial to building a seamless, precision product. Injection molds are typically constructed using steel or aluminum, and precision machined to form the features of desired product.

The injection molding process is fairly repetitive once a functional, errorless mold has been produced. It also has a low scrap rate relative to other manufacturing processes which cut away considerable portions of the original material blank in a subtractive process.

The Injection molding process is highly repeatable and reliable for high volume production. Once the first part is produced, the second is going to be practically identical, due to the ability to make multi-cavity injection mold parts, where multiple parts are made with one cycle. Other advantages are the wide range of material selection, low labor costs, minimal scrap losses, and minimal requirements to for post-molding finishing operations.

The major disadvantages of injection molding are the initial costs of the mold design, which tends to be high due to design, testing, and tooling requirements and the longer required lead times. Some custom complex parts may encounter problems during the injection molding process such as warpage or surface defects. Therefore, injection molded parts must be designed with careful consideration to any change in geometry as they cool and the material selection to assure stability.

What are The Number of Stations Required to Make the Stamping Parts

August 26, 2019 by xinghui  

The number of stations required to make the Stamping Parts (XINGHUI)—Certain metal types and thicknesses may require more stations than others. For example, designing a formed part out of high-strength steel may require one or more re qualifying stations or re strike operations. Additional special operations—When using some grades of superalloys, such as INCONEL?, you may need an additional annealing operation between forming stations. This increases manufacturing costs and slows down production. This is why aircraft parts are so expensive.

The lubricant needed to form and cut the metal—How does the metal type that the part is made from affect the lubricant used in the tooling? It's simple; higher-strength metals generate more friction than their low-carbon counterparts. As a result, they require lubricants that do not break down or "burn off" during the metal cutting or forming process.

Additional material needed to make the part—Parts made from high-strength steel, such as dual- and triple-phase steel, often have more springback problems than low-carbon steel. To help reduce the amount of springback, it frequently is necessary to increase the strain or stretch levels in the part. Achieving this often calls for the part geometry to be drawn or stretched into the finished geometry, which may require excess material on the part's perimeter so that it can be stretched over a punch. This extra material later is trimmed away and discarded as scrap.

A Brief Review on Plastic Injection Parts Moulding Manufacturing Process

August 8, 2019 by xinghui  

Various responses of quality of Plastic Injection Parts (XINGHUI) moulding process has been studied on the basis of performance parameters and methods. The term quality has become a “catch all” term used in describing the various characteristics of an object. It is nearly impossible to define the term consistency. The quality is any particular or specific characteristics of a product development design object that contains or relates information about the object. This is primarily a chunk of geometry distinguished by its ability to perform a function with one or more other. In this primary processing conditions are studied from concept development to manufacturing of the product. Effect of different factors studied on the basis of processing parameters. Since quality and productivity are the two important contradictory objectives in any machining process. Some extent of quality has to be compromised while assurance giving for high productivity. Similarly productivity will be decreased while the efforts are channelized to enhance quality. To ensure high quality and productivity, it is necessary to optimize machining parameters. This paper aims to present plastic injection moulding process conditions. The processing conditions satisfied quality based product manufacturing.
