Problems solved by technology

Processing in this way has the following defects: the length and end face diameter of the blanking material must be greater than the length and end face diameter of the finished iron stopper when blanking. Excess materials, so the waste of materials is relatively large, and the cutting process takes a lot of time, which affects production efficiency, undoubtedly increases production costs and reduces economic benefits

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] see Figure 1 to Figure 9 Shown, the processing method of iron stopper of the present invention comprises the following operations:

[0026] ①. Use a punching machine to cut and blank the round bar. The punching machine is a punching machine of 100T or above, and the weight of the blank is equal to the weight of the product body after cold extrusion molding plus the weight of the machining allowance, and then converted into the weight of the blank according to the weight of the blank after blanking. volume. The diameter of described blanking is 24.8 -0.1 0 mm, the length is 37.3±0.25mm.

[0027] ②. Chamfer the blank after blanking on the instrument car. After the round bar is cut and blanked by the punching machine, there will be burrs on the head of the blank, which will prevent the blank from being put into the mold. mold, at th...

Abstract

The invention discloses a method for processing iron blocks. The method comprises the following working procedures: (1) blanking by a punch press; (2) flatting and chamfering the blank subjected to blanking on a meter lathe; (3) cold-extruding the flatted chamfered blank into a green body of the product by the punch press; (4) drilling and chambering the cold-extruded green body of the product by a numerically controlled meter lathe; (5) truning, planning, and chamfering the green body of the product which is processed by the step (4) by the numerically controlled lathe; (6) ball-sizing the green body of the product which is processed by the step (5) by the punch press; (7) truning, planing, and chamfering the green body of the product which is processed by the step (6) by the numerically controlled lathe again; and (8) punching a notch on the green body of the product which is processed by the step (7) by the punch press, and finally forming the iron blocks. The method for processing the iron blocks has the advantages of saving raw materials, having less processing time, improving production efficiency of products, reducing production cost and improving economic benefits.

Description

technical field [0001] The invention relates to a processing method of auto parts, more precisely, relates to a processing method of an iron stopper on an automobile starter switch. Background technique [0002] Existing iron stoppers are all formed by cutting. Its specific steps are: step ①, cutting the round bar through a punching machine and blanking. The diameter of the end face; step ②, the blanking is chamfered by the flat end of the instrument lathe; step ③, the blanking after the flat end chamfering is cut and processed by the CNC lathe into a green body; step ④, the green body is finished, drilled, expanded Hole, outer circle, plane, chamfering, punching, outer circle, plane, chamfering, punching, and finally forming the iron stopper. Processing in this way has the following defects: the length and end face diameter of the blanking material must be greater than the length and end face diameter of the finished iron stopper when blanking. Excess materials, so the wa...
