Problems solved by technology

[0003] At present, in the field of stamping manufacturing of bearing cages, the first process of bearing cages stamped by steel plates is blanking. The blanking is calculated according to the calculation area of ​​the cage and the sheet is cut into a ring shape. The outer diameter is to keep The minimum size of the rack blanking, the positioning size of the next process of the inner diameter, the second process is forming, positioning according to the inner hole of the blanking, forming the outer diameter angle, forming the end face angle, and the thir

Example Embodiment

[0023] In order to in-depth the stamping bearing cage self-positioning cutting bottom forming precision mold, combined figure 1 The description is as follows: stamping bearing cage self-positioning cutting bottom forming precision mold, including stamping die upper template, return body, forming plate, forming concave mold, cage, bottom cutting punch, positioning rod, forming punch, lower template , Cutting bottom material core, punching rod, etc. make up a precision compound functional mold.

[0024] Structure principle: The center hole of the template of the stamping bearing cage self-positioning and bottoming forming precision mold passes through the punching rod, and is fixed on the punch on the punching equipment by bolts. The return body is installed on the inner side of the forming plate and is formed at the lower end of the punching rod. The plate is pressed on the bottom end of the bearing cage when the inner side of the molding die is working. The molding die is fixed t...

Abstract

The invention belongs to the field of stamped bearing retainer machining, and relates to a retainer forming die, in particular to a self-positioning bottom blanking and forming precise die for a stamped bearing retainer. The die comprises an upper die and a lower die; the upper die comprises an upper die plate, a pushing body, a forming plate, a forming female die and an ejector rod; the lower die comprises a bottom blanking male die, a positioning rod, a forming male die and a lower die plate. By adopting the self-positioning bottom blanking and forming precise die for the stamped bearing retainer, the effect of combining two processes into one forming and bottom blanking process is achieved, work efficiency is improved, forming quality is improved, and the manufacturing cost of one die can be omitted as well.

Description

[0001] technical field [0002] The invention relates to a mold for forming a cage, in particular to a precision mold for self-positioning and bottom-cut molding of a stamping bearing cage, which belongs to the field of bearing stamping cage processing. Background technique [0003] At present, in the field of stamping manufacturing of bearing cages, the first process of bearing cages stamped by steel plates is blanking. The blanking is calculated according to the calculation area of ​​the cage and the sheet is cut into a ring shape. The outer diameter is to keep The minimum size of the rack blanking, the positioning size of the next process of the inner diameter, the second process is forming, positioning according to the inner hole of the blanking, forming the outer diameter angle, forming the end face angle, and the third process is cutting the bottom. The excess inner diameter metal of the formed cage is removed on the press through the mold. The disadvantage of this pro...
