Problems solved by technology

However, the cost of the purchased finished oil plug seat is relatively high, which undoubtedly increases the production cost of the finished product of the rear oil cap; and the oil plug seat is welded to the rear oil cap through the welding process to facilitate sealing with the plug (oil plug) The rear oil cover is prone to leakage defects, and the first-time yield is low, which often needs to be improved by repair welding measures, which undoubtedly reduces the production efficiency of the rear oil cover.

Embodiment 1

[0034] A rear oil cover forming process, comprising the steps of:

[0035] S1, blanking: the whole original plate is cut into a plurality of rectangular blocks by a shearing machine, the size of any one of the blocks is sufficient to complete the forming of the rear oil cap, and the original plate is made of a Q235A steel with good toughness, plasticity and hot workability;

[0036] S2. Blanking: the block material is punched into a circular workpiece that is convenient for forming the rear oil cover through a punching machine, thereby avoiding the sharp corner cracking and poor material flow of non-circular workpieces in the subsequent drawing process. In case of uneven material flow;

[0037] S3, drawing: coating the inner and outer sides of the circular workpiece with drawing oil, and then drawing the circular workpiece coated with drawing oil into the shape of the rear oil cover through a hydraulic press, The coating of drawing oil can not only ensure the surface process...

Embodiment 2

[0044] The drilling tool used in the described a kind of rear oil cap forming process, such as figure 1 , 2 As shown, it includes a base 10 fixed on the drilling machine workbench. The upper surface of the base 10 is fixed with four positioning plates 20 by bolts. The four positioning plates 20 are distributed along the circumferential direction, and the four positioning plates 20 are distributed along the circumferential direction. The area between the positioning plates 20 constitutes the placement area of ​​the rear oil cover; the placement area of ​​the rear oil cover on the base 10 is fixed with a support positioning block 30 by screws, and the upper surface of the support positioning block 30 is in contact with the rear oil cover. The inner surface of the hole to be drilled coincides, the setting position of the support positioning block 30 in the placement area of ​​the rear oil cover corresponds to the setting position of the rear oil cover to be drilled in the rear oi...

Abstract

The invention belongs to the technical field of rear oil cap production and manufacture, and relates to a rear oil cap molding technology and a drilling tool used in the technology. The rear oil cap molding technology comprises the following steps of, S1, feeding; S2, blanking; S3, drawing; S4, edge modifying; S5, hole drilling; S6, tapping; and S7, leak testing. According to the rear oil cap molding technology, production cost of the rear oil cap is reduced, rejection rate in the production process of the rear oil cap is reduced, and production efficiency of the rear oil cap is improved.

Description

technical field [0001] The invention belongs to the technical field of production and manufacture of rear oil caps, and in particular relates to a rear oil cap forming process and a drilling tool used in the process. Background technique [0002] The automobile drive axle housing is one of the main load-carrying components on the car, and it is indispensable, while the rear oil cover is an important component of the automobile drive axle housing. Under the booming environment of the automobile industry, the demand for the rear oil cover is increasing day by day Big. [0003] The existing forming process of the rear oil cap is blanking, blanking, drawing, trimming, punching, and then outsourced to purchase the finished oil plug seat, and then the oil plug seat is welded to the through hole of the rear oil cap, and finally Leak test. However, the cost of the purchased finished oil plug seat is relatively high, which undoubtedly increases the production cost of the finished p...
