High-speed punch is an integrated special cast iron alloy, which is widely used in the stamping of small precision parts such as precision electronics, communications, computers, household appliances, auto parts, motor stator and rotor. High-speed punch often appear brake disc ring gear tooth wear and so on. The wear is very severe and uneven, which cannot be solved by traditional methods. We can use this quick repair technology to solve the wear problem of the shaft keyway of the high-speed punch.

We can use this quick repair technology to solve the wear problem of the shaft keyway of the high-speed punch.

Only reasonable analysishigh speed punch pressShaft keyway wear reasons, in order to properly repair the equipment. The specific wear of the equipment is as follows:

This equipment belongs to continuous stamping equipment. The flywheel has a large moment of inertia during operation, which causes a large torque and impact on the ring gear during braking, so the ring gear and gears of the brake disc are prone to gearing. At the same time, the fit between the gear and the shaft diameter relies on the flat key to transmit torque. In the case of frequent impact and two-way impact, the keybar is easy to roll, causing the keyway to wear and widen. Continuous operation will result in the failure to transmit the corresponding torque, which is a common problem with this type of equipment.

In the case that the traditional method cannot be repaired, the carbon nano polymer material technology can be used to repair the shaft keyway wear on site. The material has good adhesion, good compression resistance, wear resistance and metal elastic deformation and other comprehensive mechanical properties, to achieve online repair. The repair efficiency is high and does not require a lot of disassembly equipment. In general, the repair can be completed within 8 hours.

The specific maintenance process of shaft keyway wear is as follows:

(1) Bake the oil on the surface of oxyacetylene until there is no spark. Do not bake the same part repeatedly;

(2) Use a polishing machine to polish the repaired surface to remove the high points, and use anhydrous ethanol to clean the repaired surface to ensure that the repaired surface is rough, clean and dry;

(3) blending carbon nano polymer material SD7101H, coating on the repair surface, scraping along the benchmark;

(4) Due to the large amount of wear, it is necessary to coat the material many times and use the repair tooling to repair it to the standard shaft diameter;

(5) Try to assemble the keyway with standard keys, and then coat the material to form;

(6) Heat the gear parts for thermal assembly.
