Embodiment

[0029] A thread rolling wheel repair process, comprising the following steps:

[0030] S1. Fix the damaged thread rolling wheel;

[0031] S2. Use a tool to break off the teeth along the extension direction of the teeth of the broken thread rolling wheel to obtain a repair area;

[0032] First of all, expanding the repair area can increase the connection strength between the repair metal and the original metal. By only destroying the extended area of ​​the fractured tooth without destroying other places, the strength of the teeth in other places can be guaranteed.

[0033] S3. Use a hole turning machine to drill holes on the repaired area of ​​the thread rolling wheel; the direction of the hole points to the center of the thread rolling wheel, and the diameter of the hole increases with the increase of the depth, so that the installation between the hole and the thread rolling wheel is fixed The cavity is connected; the bottom of the hole is filled with metal carbon powder.

Abstract

The invention discloses a thread rolling die repair process. The thread rolling die repair process comprises the following steps: (S1) a damaged thread rolling die is fixed; (S2) teeth are broken in the tooth extension direction of the damaged thread rolling die by using a tool to obtain a repair area; (S3) the repair area of the thread rolling die is punched; (S4) the repair area is separated from other complete areas by filling metal carbon powder in gaps between the teeth; and the metal carbon powder is a mixture of metal powder and carbon powder; (S5) the repair area is heated by using a high-frequency heating coil; molten metal is injected in the repair area; and the repair area is heated by using the high-frequency heating coil; and (S6) after the repair area is cooled, a repairer iscut as the thread rolling die by using a cutting tool; and the thread rolling die is totally annealed and quenched. The thread rolling die repair process repairs tooth-broken thread rolling dies, sothat the thread rolling dies can be continuously used normally.

Description

technical field [0001] The invention relates to the field of finishing, in particular to a repairing process of a thread rolling wheel. Background technique [0002] The thread rolling wheel is a tool that uses the method of metal plastic deformation to roll out the thread on the thread rolling machine. Due to its working characteristics (relying on its own hardness to roll the thread), the thread rolling wheel needs to have high hardness and certain toughness. [0003] After the thread rolling wheel has been used for a period of time, the teeth of the thread rolling wheel will break. At this time, only a new thread rolling wheel must be replaced. However, due to the high price of thread rolling, and the purchase needs a certain period of time, so for the enterprise Production caused some confusion. Contents of the invention [0004] In view of the above-mentioned defects in the prior art, the purpose of the present invention is to provide a thread rolling wheel repair p...
