Problems solved by technology

The workpiece is held and rotated by the machine tool, and the cutting tool is used to cut the shape, so there is waste cutting material, and the quality of the bearing fixing sleeve will continue to change with the loss of the tool, and the turning process for the bearing fixing sleeve will make the product production cycle Lengthening, resulting in reduced output, increased cost, short quality cycle, and it is not possible to process bearing fixing sleeves with axial grooves

Embodiment

[0019] Example: such as figure 1 , figure 2 , image 3 , Figure 4 As shown, a method for processing a bearing fixed sleeve with a cold extrusion process includes the following steps:

[0020] A. Place the blank of the bearing fixing sleeve 1 into the cavity 2 of the cold extrusion die;

[0021] B. Clamp the mold to form the shape of the bearing fixed sleeve 1, and stamp the inner cavity 4 of the bearing fixed sleeve 1 with the punch 3;

[0022] C. Open the mold, and eject the formed bearing fixing sleeve 1 with the ejector pin 5 .

[0023] A device for processing a bearing fixed sleeve with a cold extrusion process, including a cold extrusion die, the cold extrusion die includes a front die 6 and a rear die 7, the rear part of the front die 6 and the front part of the rear die 7 are molded Cavity 2, when the front mold 6 and the rear mold 7 are closed, the mold cavity 2 has the same shape as the bearing fixed sleeve 1, and the front part of the front mold 6 is provided ...

Abstract

This invention discloses a method of processing gearing fixation cover using cold extrusion technique and its equipment. Materials' plasticity is used to forming through linear to-and-fro in cold extrusion mould. It can improve output and reduce cost, prolong quality period. Gearing fixation cover with axial sinew flute can be processed, and cold hardening phenomenon in the processing of cold extrusion is fully used to improve product hardness.

Description

technical field [0001] The invention relates to a method and a device for processing a bearing fixed sleeve by a cold extrusion process. Background technique [0002] In the prior art, the bearing fixing sleeves are all completed by turning. The workpiece is held and rotated by the machine tool, and the cutting tool is used to cut the shape, so there is waste cutting material, and the quality of the bearing fixing sleeve will continue to change with the loss of the tool, and the turning process for the bearing fixing sleeve will make the product production cycle Lengthened, resulting in reduced output, increased cost, short quality cycle, and can not be processed bearing sleeve with axial grooves. Contents of the invention [0003] The purpose of the present invention is to provide a method and device for processing bearing fixed sleeves by cold extrusion technology, which can increase production, reduce costs, and prolong quality cycle , It can also process bearing fixi...
