Thread rolling plate

Analysis of tooth loss at the tip of screw thread over M6 thread board causes tooth loss and skin loss:

In the process of rolling, the tip part of the alloy mold shall be extruded into a 50-degree tip by a straight smooth rod to produce a large amount of surplus material. The residual material generated shall be digested in two ways:

One: discharge out, generate residual material (commonly known as iron excrement);

Second: in the tip part of the extrusion teeth.

Improvement methods are as follows:

One, M6 above the grinding board, the tip part milling teeth than the general specifications milling teeth deep milling larger, so that the excess residue can be attached to the tip.

Two, when feeding the wire board to increase the discharge, nut mold to make the excess residual material produced into iron excrement.

Screw factory can be improved in the following aspects:

The length of the screw is strictly controlled (shorter than the length of the screw).
