2results about How to "Avoid Surface Quality Issues" patented technology

The application discloses a kind of process method and fixture of processing wedge type locking block, method includes S1 preparation plate material;S2 blanking to plate material;S3 heat treatment plate material as blank;S4 numerical milling processing 1: numerical milling blank, drilling forms light hole and thread bottom hole, thread bottom hole tapping processing;S5 numerical milling processing 2: cutting blank;S6 surface passivation treatment;S7 to final inspection;For the fixture for processing wedge type locking block includes clamping seat, pressing plate, first locking screw and second locking screw, clamping seat is provided with clamping through slot, first threaded hole and mounting hole, pressing plate is provided with second threaded hole;By improving process method, multiple process contents are combined, clamping frequency is reduced, semi-finishing requirement in process is increased, no burr can be generated in process, because clamping frequency is reduced, part surface quality is improved;Raw material utilization is higher, is half of all materials of original process scheme, total amount of waste gas emission is reduced by half compared with original process scheme.

This utility model relates to the field of quenching technology for high-elasticity spring production, specifically a rapid quenching device for stainless steel bars used in high-elasticity spring production. The device includes a base column and a worktable. An induction control box is fixedly connected to the upper surface of the worktable. Three induction copper tubes, all arc-shaped, are provided on one side of the control box. A clamping device is provided on the upper surface of the worktable, comprising a sliding groove. The groove is formed on the upper surface of the worktable, and a first screw is rotatably connected to the inner wall of the groove. A slider is slidably connected to the inner wall of the groove, and the slider is threadedly connected to the first screw. This utility model solves the problem that existing quenching equipment requires manual clamping of the bars using special tools, which easily leads to burns to operators during quenching and significantly increases labor costs due to prolonged clamping.
