Embodiment Construction

[0013] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0014] As shown in the figure: a fixed and fixed ring quenching fixture, including an upper splint 1, a lower splint 2, bolts 3, and a pit 4.

[0015] A through hole is arranged at the center of the upper splint 1 and the lower splint 2, and several through holes are distributed around the central through hole. Pit 4. The dimples 4 are evenly distributed on a central circumference of the lower splint 2 . When quenching and heating, the boss of the product is placed in the lower splint, so that the plane of the product is in contact with the plane of the lower splint, which can effectively reduce thermal deformation; several through holes distributed around the central through hole play the role of heat transfer; tempering The quenched parts are neatly superimposed on the lower splint, and the splint is added, fixed with bolts on the press, and then tempered, which i...

Abstract

The invention relates to a clamp, especially relates to a quenching clamp of a stationary integrated ring. The quenching clamp comprises an upper clamping plate, a lower clamping plate, bolts and pits. A through hole is arranged at the central part of the upper clamping plate and the lower clamping plate, several through holes are distributed around a central through hole, bolts pass through the central through hole of the upper clamping plate and the lower clamping plate, several pits are distributed around the central hole of the lower clamping plate. a convex plate on the product is placed in the corresponding pit of the lower clamping plate, heating deformation during heat treatment quenching can be reduced, the quenching members are tidily overlapped on the lower clamping plate after quenching and before tempering, the upper clamping plate is added and fixed on a press by bolts, then a tempering treatment is carried out for correcting the warpage.

Description

technical field [0001] The invention relates to a clamp, in particular to a quenching clamp with a fixed and fixed integral ring. Background technique [0002] The material of the fixed integral ring is bearing steel. The fixed and fixed integrated ring has a large outer diameter, thin thickness, 18 pits evenly distributed along the center diameter, and 18 corresponding bosses on the reverse side. The hardness requirement is high, and after heat treatment, in addition to the need for hinge positioning holes and overall finishing , Without other mechanical processing, it is prone to deformation during punching and quenching, resulting in inconsistent central diameters of 18 pits and scrapping. Contents of the invention [0003] The invention provides a fixed-stop integrated ring quenching fixture, which solves the above-mentioned problem of workpiece deformation caused by punching and quenching treatment. [0004] The present invention adopts following technical scheme: ...
