Special screw thread rolling process standard is not the same

The washboard of special screws is different from the standard washboard, because the special screws are non-standard screws and belong to non-standard screws, so the washboard used may need to be customized. Of course, it is generally available, as long as your location is not too remote, it is easy to buy in the screw production base.

The process of rubbing special screws is divided into several steps. The following is an explanation:

1. First replace the previous washboard, and then replace it with a custom-made special-shaped washboard.

2, special screws to start debugging; After the thread washboard is installed, it takes a long time to debug, and it takes an hour or two for ordinary technicians to debug.

3. Special screws start production; After debugging, it can be produced.

Special screw processing principle professionals, so simple knowledge in this show off. But for the majority of ordinary people, this may not be known, unless you have visited the screw factory to learn. There are two kinds of screw thread forming process, one is cutting processing: the other is extrusion processing.

Special screw cutting is generally lathe processing, that is, to find an iron rod is the round rod of the material you need. The diameter of the round rod is the larger outer diameter size of the special screw. For the processing of tooth-shaped vehicle tools, the front end of the turning tool should grind the size of the screw tooth shape, otherwise the assembly will be affected. Then the thread is machined by lathe. The popular point is to hollowed out the excess material of the round bar into thread through a turning tool. This kind of machining method is suitable for small batch and high precision machining. But the processing cost is high and the efficiency is low.

Special screw extrusion processing is processed by professional screw equipment, screw factory industry called rolling machine. The diameter of the iron rod is the intermediate value between the larger size at the top of the screw and the smaller size at the bottom of the screw. Using the flow properties of metal materials through the mold high-speed extrusion molding, extrusion processing can achieve mass automation production, and stable quality. Low cost and high efficiency Suitable for mass production.
