Abstract

The utility model belongs to a heat treatment tool, and relates to a collision and deformation preventing fixture for quenching of a bearing ring. The collision and deformation preventing fixture is characterized by comprising an iron gauze or steel gauze capable of wrapping the bearing ring inside. According to the collision and deformation preventing fixture for quenching of the bearing ring, the iron gauze or steel gauze is bent to be of a U shape, and the bearing ring is wrapped in the iron gauze or steel gauze. The collision and deformation preventing fixture has beneficial effects that because collision is caused during violent rigid contact, a bearing is wrapped by using the iron gauze so that the surface of the bearing can be prevented from being in rigid contact with the outside, the iron gauze plays a role in buffering, and the collision and deformation of quenched parts are effectively avoided; and the collision and deformation preventing fixture is safe and reliable, convenient for use and simple in structure. Meanwhile, the heat treatment efficiency of the bearing is greatly increased, and the cost is lowered.

Description

Bearing ring quenches and prevents knock damage, distortion frock

Technical field

The utility model belongs to the thermal treatment instrument, relates to the anti-knock damage of a kind of bearing ring quenching, distortion frock.

Background technology

Bearing products is high to appearance requirement, has not generally allowed the macroscopic irregularitys such as knock damage.Now, be processed into a kind of trend with the meshbeltfurnace tempering of quenching, replace salt bath furnace and box-type furnace to become raising the efficiency and quality stability, a kind of effective way of reducing production costs with meshbeltfurnace.But meshbeltfurnace production also has its weak point, and processing medium-and-large-sized workpiece generation knock damage is exactly an insoluble difficult problem.

Summary of the invention

The utility model provides a kind of bearing ring simple in structure, esy to use, safe and reliable to quench and has prevented knock damage, distortion frock in order to remedy the deficiencies in the prior art.

The utility model is achieved by the following technical solution:

Bearing ring of the present utility model quenches and prevents knock damage, distortion frock, and its special character is: comprise wire netting or woven wire in bearing ring can being wrapped in.

Bearing ring of the present utility model quenches and prevents knock damage, distortion frock, and wire netting or woven wire bending take the shape of the letter U, in bearing ring is wrapped in.

Bearing ring of the present utility model quench anti-knock damage, distortion frock, wire netting or the doubling of woven wire two ends and link together and consist of the pie structure or two ends are oval-shaped flat barrel structure are in bearing ring is wrapped in.

Perhaps, wire netting or woven wire are tubbiness.

The beneficial effects of the utility model are, because knock damage is to produce when fierce rigidity contact, bearing ring wrapped up with wire netting can avoid bearing ring surface to contact with the rigidity in the external world, wire netting has played shock absorption at this, effectively avoid part knock damage, the distortion of quenching, safe and reliable, easy to use, simple in structure.And greatly improved the bearing heat treatment efficiency, reduced cost.

Description of drawings

Fig. 1 is use synoptic diagram of the present utility model.

Among the figure, 01, bearing ring, 02, wire netting.

Embodiment

Accompanying drawing is a kind of specific embodiment of the present utility model.

Bearing ring of the present utility model quenches and prevents knock damage, distortion frock, comprises wire netting 02 or woven wire in bearing ring 01 can being wrapped in.

Wire netting or woven wire bending take the shape of the letter U, in bearing ring is wrapped in.Perhaps, wire netting or the doubling of woven wire two ends and link together and consist of the pie structure or two ends are oval-shaped flat barrel structure are in bearing ring is wrapped in.Perhaps wire netting or woven wire are tubbiness.

This product is to quench for the bearing ring 01 that on meshbeltfurnace wire netting 02 is wrapped up.Bearing wrapped up with wire netting can avoid bearing surface to contact with extraneous rigidity, wire netting has played shock absorption at this, effectively avoids part knock damage, the distortion of quenching.Bearing is suitable for 2 kilograms with head bearing with being placed on behind the wire netting parcel to quench on the meshbeltfurnace, can reaches the maximum weight that meshbeltfurnace allows processing, greatly improved the bearing heat treatment efficiency, reduced cost.

Claims
