An improved quenching partition for thin ring parts and its processing method

Abstract

The invention relates to an improved thin circular ring piece quenching partition plate which comprises a ring body and a plurality of outer teeth extending in the radial direction of the ring body. Aliquid passing groove is formed by the space between every two adjacent outer teeth and the outer ring side of the ring body. The front side and the rear side of each outer tooth are each provided with an outer tooth liquid passing square groove in a milling mode. The groove width of each outer tooth liquid passing square groove is the same as the width of the corresponding outer tooth. The outertooth liquid passing square grooves are evenly staggered on the front side and the rear side. The width of the outer teeth of the quenching partition plate is increased, the diameter is increased, the deformation of the quenching partition plate is reduced, the number of leveling times is reduced, the service life is prolonged by three times or more, the clamp maintenance cost is reduced, and production efficiency is improved; meanwhile, the supporting range of the quenching partition plate for the thin a thin circular ring piece is enlarged, and the twisting elastic deformation of the thin circular ring piece is further controlled; the front sides and the rear sides of the outer teeth are provided with the outer tooth liquid passing square grooves in the milling mode respectively, the contact area of the quenching partition plate and the thin circular ring piece is evenly distributed, and the quenching uniformity is improved; in addition, coolant can enter the outer tooth liquid passing square grooves to make contact with the thin circular ring piece, the quenching uniformity can be further improved, and the hardness soft point is avoided.

Description

technical field [0001] The invention relates to the technical field of parts processing, in particular to an improved quenching partition for thin circular ring parts and a processing method thereof. Background technique [0002] Thin rings with a thickness of 1.5mm to 4mm (such as Figure 1-2 As shown) parts, the material is 65Mn or other spring steel. After heat treatment, the hardness is required to be uniform, no soft spots are allowed, and the flatness tolerance is strict; this kind of large-size spring steel parts of thin plates are heated at high temperature during quenching, and the parts It is difficult to guarantee the flatness. [0003] Adopt a kind of thin ring piece quenching fixture 100 (such as Figure 3-5 shown), including: a lower backing plate 110, an upper backing plate 120, a quenching partition 130, bolts 140, and nuts 150. This quenching fixture solves the problem of clamping and quenching after multi-piece stacking, which is easy to produce hardness ...
