The traditional closing method is: designing a closing tool, and expanding and deforming the copper bushing at the closing position to complete the closing processing of the bushing, which has the following disadvantages: 1. The tooling is complicated, and the design and manufacture are very difficult; 2. Bushing material fills unevenly in slots, high scrap rate

Embodiment Construction
[0021] In the following, with reference to the accompanying drawings and preferred embodiments, the specific implementation, features and effects of an extrusion processing method for filling copper bushings in the holes of steel parts according to the present invention will be described in detail as follows.
[0022] See Figure 5-9, an extrusion processing method for filling copper bushings in the holes of steel parts. Firstly, the extrusion tool is made. Figure 5 , 6 As shown, the main body of the extrusion knife is composed of a guide 3, an arc-shaped extrusion working surface 4, and a knife rod 5. The guide 3 is a tapered surface, and the outer diameter of the arc-shaped extrusion working surface 4 is larger than the diameter of the copper bushing. The diameter of the arc-shaped extrusion working surface 4 of the first stage is larger than that of the previous stage. The inner hole of the bushing is extruded by the extrusion knife, so that the diameter of the hole is cont...

The invention discloses an extruding processing method for filling a steel element hole with a copper bushing. The method is characterized in that firstly, an extruding tool is manufactured, an extruding cutter main body is in an arc-shaped dimension gradual increase type and is of a rotating body structure, the extruding cutter main body consists of a guide (3), an arc-shaped extruding work surface (4) and a cutter rod (5), the guide (3) is a conical surface, the outer diameter dimension of the arc-shaped extruding work surface (4) is greater than the hole diameter of the copper bushing, the diameter of a later stage of arc-shaped extruding work surface (4) is greater than that of a former stage, and the hole diameter is continuously increased through extruding a bushing inner hole by an extruding cutter, so that the copper bushing (2) is continuously embedded into a groove of a steel casing (1), the copper bushing (2) is enabled to be extruded into the groove in a hole of the steel casing (1) to realize the uniform filling, and the processing requirements are met. The extruding processing method has the advantages that the tool manufacturing is simple, the realization is convenient, high requirements are not required on the equipment, the processing can be completed by using the existing mature processing technology and equipment, and good manufacturability is realized.
Description
technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to an extrusion processing method for filling copper bushings in holes of steel parts. Background technique [0002] In the field of mechanical processing, there is a special structure processing, such as figure 1 , 2 As shown (representing the structure only), the copper bushing is pressed into the steel shell hole to meet the wear resistance requirements of the hole. This structure requires the copper bushing base to be embedded in the shell annular groove (such as image 3 , 4 shown), and completely fill the housing slot to prevent the bushing from slipping during use. The traditional closing method is: designing a closing tool, and expanding and deforming the copper bushing at the closing position to complete the closing processing of the bushing, which has the following disadvantages: 1. The tooling is complicated, and the design and manufacture are very diff...
