A kind of plastic wire drawing machine screw rod is with laser cladding device of wear-resistant layer

By employing a point-contact clamping mechanism in the laser cladding device for the wear-resistant layer of the screw in a plastic wire drawing machine, the problem of clamping damage when the cladding layer at the screw end is not cured in the existing technology has been solved. This enables continuous cladding of the wear-resistant layer on the entire surface of the screw, improving wear resistance and service life, and reducing production costs.

AI Technical Summary

Technical Problem

Existing technologies struggle to address the issue of complete wear-resistant layer preparation when clamping the screw at its end region. Specifically, existing technologies cannot independently prepare wear-resistant alloys. Furthermore, in current laser cladding processes, clamping the screw before the cladding layer at the end is fully cured leads to cracking and peeling, impacting service life and production costs.

Method used

A laser cladding device for wear-resistant layer of plastic wire drawing machine screw is designed. It adopts a point-contact clamping mechanism, which fixes the screw substrate to non-machined surface through contact of the pressure block, avoiding extrusion damage to the incompletely cured wear-resistant layer and realizing continuous cladding of the entire surface of the screw.

Benefits of technology

It achieves continuous cladding of the wear-resistant layer on the entire surface of the screw, improving the overall wear resistance and service life of the screw, and reducing production costs and processing cycle.

Abstract

This invention discloses a laser cladding device for wear-resistant layers on plastic wire drawing machine screws, comprising a slide table, a robotic arm assembly fixedly connected to the top of the slide table, a welding head fixedly connected to the top of the robotic arm assembly, bases respectively provided on both sides of the slide table, and a turntable three rotatably connected to the top of the base. The turntable three has several annularly distributed grooves. This invention, through a point-contact clamping mechanism, can switch the surface contact clamping of the pressure plate to the point-contact clamping of the pressure block when cladding the end of the screw. By precisely adjusting the position of the pressure block, it avoids the already clad wear-resistant layer area and only contacts and fixes with the non-processed surface of the screw substrate. This ensures rotational stability during single-end processing and completely avoids damage such as squeezing cracks and peeling caused by the clamping mechanism to the incompletely cured wear-resistant layer, realizing continuous cladding of the entire surface of the screw from the main body to the end.
