Abstract

The invention belongs to the field of E-shaped holding rack compressing moulds for second-class roller bearings, overcomes the shortages in the prior art, and provides an E-shaped rack riveting mould for a roller bearing, which has low probability of scratching and small working noise, and can solve the shortages. The adopted technical scheme of the E-shaped rack riveting mould is that a main mould body is arranged on a baseplate; an outer rising sliding block is arranged in the main mould body; the outer side shape of the outer rising sliding block is fit with the inner side shape of the E-shaped holding rack for the roller bearing; a first spring enabling the outer rising sliding block to reset is further arranged outside the outer rising sliding block; a tapered through-hole is formed in the outer rising sliding block in the vertical direction; the upper part of a punch is cylindrical, and the lower part is conical; the lower part of the punch is matched with the tapered through-hole of the outer rising sliding block; a guide sleeve for guiding the punch to move upward and downward is arranged at the upper part of the main mould body; and a second spring enabling the punch to reset upward is arranged on the baseplate. The E-shaped rack riveting mould provided by the invention is mainly used for the field of roller bearing production.

Description

technical field [0001] The invention belongs to the compression mold of the E-shaped cage of the second type of roller bearing, and in particular relates to a riveting mold of the E-shaped cage of the roller bearing. Background technique [0002] In the manufacturing process of short cylindrical roller bearings, copper cages were originally used. Due to the high price of copper materials recently, in order to reduce costs, various alternative materials have emerged. As an alternative material for E-shaped steel plate cages, low-carbon steel plates The most widely used. [0003] When the E-shaped cage is assembled with the bearing, in order to fix the roller, it needs to be deformed to a certain position to lock the roller. At first, the lever manual type is used, and only two pieces of ears can be pressed at a time to fix one roller. The operation is slow. , and the force is uneven, the rollers are loose and close to the operator's control, it is difficult to unify, and the...
