Embodiment Construction

[0018] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so that the protection scope of the present invention can be more clearly defined.

[0019] Such as figure 1 As shown, the process for processing a cold-heading sleeve of the present invention, the specific steps are as follows:

[0020] (1). Screen and inspect the blank materials. According to the specific requirements of the product, carry out corresponding incoming inspections on the blanks and select the appropriate size blank materials. The blank is a round bar with a diameter of 39mm and a weight of 390g ;

[0021] (2) Choose a multi-station cold heading machine to directly cold head the shape, and process it into the required product size through four cold heading;

[0022] (3) The outer round flat head chamfer of the turnin...

Abstract

The invention discloses a cold heading sleeve processing process, which comprises the following concrete steps: (1) screening and inspecting blank materials, carrying out corresponding incoming inspection on the blanks according to the specification of a product, and selecting the blank materials with right size, wherein the blanks are round bar materials with the diameter of 39mm and the weight of 390g; (2) selecting and using a multistage cold former for direct cold heading form, and processing to obtain required product size through four times of cold heading; (3) turning excircle chamfering R1 of the blanks, and inspecting if the product is qualified or not after chamfering; (4) rough machining an inside groove reserved by the blanks, finishing machining the inside groove, and carrying out product inspection on the blanks after finishing machining the inside groove; (5) electroplating the blanks; and (6) packaging and storing the finished products after electroplating. For each product, the blank usage amount is saved by 231.9g, so that the cost is reduced by 37.29 percent, the processing difficulty is reduced, the consumption is reduced, the processing cost is saved, and meanwhile, the production efficiency is improved.

Description

Technical field [0001] The invention relates to a process for processing a cold heading sleeve. Background technique [0002] The traditional craft method is outsourcing Rough round, blanked by punch, weight is about 621.9g, processed into rough after annealing and shaping, use Solid bar, the weight of the formed blank is 621.9g, the red-beating blank has a large margin, the output is too slow, the shape is irregular, the deformation is large, and the size of the blank assembly is unstable. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a cold heading sleeve processing technology with less machining allowance, tool saving, uniform appearance, stable size, reduced processing difficulty, reduced consumption, saving processing cost and improving production efficiency. [0004] The present invention is realized through the following technical solutions: a cold heading sleeve processing technology, the specific steps are as f...
