Compression spring, commonly known as compression spring, is this kind of spiral spring product that bears the working pressure. The cross section of the raw material is mostly ring-shaped, and it is also produced by rectangular frame or multi-core steel. The coil of the compression spring has The necessary clearance, this clearance is called pitch/tooth pitch, usually equal pitch, when subjected to external load, the spring collapses to produce deformation and stores the deformation energy; the key to the appearance of the compression spring is: cylindrical, Conical, convex, concave shapes and a small amount of non-circular shapes.
For the compression spring machine, its key product technical parameters include: wire diameter, diameter, pitch, length, break flatness and burrs, etc. It is smarter to use a relative compression spring machine to form. How to manipulate the precision of various main parameters in the whole process of adjusting the compression spring? The key involves giving multiple levels:
① Provisions on equipment characteristics. There are many spring machine manufacturers in the market at this stage. Different manufacturers produce CNC spring machines, and their hardware and software have different performance enhancements.
②Quality regulations for work clothes molds. The quality of the spring machine work clothes mold is immediately decided on the main parameters of the quality of the spring and the work efficiency, such as the wire feeder, the transmission line board, the curve graph gauge, the hob and the pitch knife, etc., and the manufacturer's model adds the general full It is a standard configuration mold, and there are differences in the quality of molds made by different manufacturers.
③Use the quality regulations of wire. Each spring product has the necessary regulations for the wire. If the same spring uses different wires with different compositions, the main physical characteristics shown are different. Therefore, the use of wires with different compositions determines the actual quality effect of spring products after forming.
④ Adjust the technical standards of the staff. The computer spring machine that is popular in China at this stage requires human factors to participate in the actual operation. The key is related to the adjustment of the product. After adjusting a spring product, the device can continue to run (common Beyond the problem of failure). In the whole process of adjusting the equipment, the distribution of special tools and the grinding and polishing of molds are the most critical tasks for the spring machine master.
