Processing principle of special screws

Screws as industrial rice, all walks of life need to use screws, but special screws are different from ordinary screw fasteners. In many cases, designing accessories with the development of new products is particularly important for the development of an enterprise, which determines the quality and sales of new products. Special screws are difficult to manufacture screws with large deformation. Some small screw manufacturers cannot manufacture screws with a single device. Then, let's learn about the processing principle of special screws!

The principle of the machining of special threads may be despised by experts, but such simple knowledge is shown here. However, for most users, the processing principle of special threads is not necessarily known. Unless you and Xiaobian often visit the special thread factory, know the production process of special thread. Screws and screw machines have been invented and manufactured by British people for more than 200 years. It really has a long history. Today, the society generally does not say much. Today, let's talk about the processing technology of special threads. There are two kinds of special thread processing technology. One is cutting. The other is extrusion processing.

Cutting is generally lathe processing, playing the required material round bar. The diameter of the round bar is the larger outer diameter dimension of the special thread. Tooth type opening edge processing, the size of the front end of the turning tool grinding thread tooth type is the key, otherwise it will affect the assembly. Then, the thread was cut by opening the bed. The general place is to use a knife to dig out the excess material of the round bar to make threads. This processing method is suitable for small batch, high precision processing requirements. However, the processing cost is high and the efficiency is low. The cost of general lathe processing is 1-2 times more expensive than that of cold heading production.

Extrusion processing is processed by professional thread equipment, and the company's thread manufacturer is called a picker. Cold heading formed screw fasteners use screw wire instead of horizontal bar. The diameter of the screw wire is an intermediate value between the larger dimension of the front end of the screw and the smaller dimension of the lower end of the screw. Using the fluidity of metal materials, high-speed extrusion forming is carried out through the mold, so that the extrusion processing can realize mass production automation and stable quality. Low cost, high efficiency, suitable for mass production, mass production.

Screws as industrial rice, all walks of life need to use screws, but special screws are different from ordinary screw fasteners. In many cases, designing accessories with the development of new products is particularly important for the development of an enterprise, which determines the quality and sales of new products. Special screws are difficult to manufacture screws with large deformation, and some small screw manufacturers cannot manufacture screws with a single device.

The above introduction is the processing principle of special screws. Thread factories generally use extrusion processing. If you do not know the principle of thread processing, please feel free to visit Shitong Special Thread Factory.
