Automobile driven rear axle oil retaining disc blanking-forming composite die without overlapping and composite process

Abstract

The invention relates to an automobile driven rear axle oil retaining disc blanking-forming composite die without overlapping. The die comprises an upper die part and a lower die part. The upper die part comprises a die handle, an upper die plate, a guide sleeve, a washer, a discharging spring, a knockout block, an upper base plate, a blanking male die and a forming female die; the lower die partof the die comprises a blanking female die, a forming male die, a stop pin, a blank holder, a guiding column, a die rectifier, a lower base plate, a lower die plate and an ejection rod. The blanking-forming process of the oil retaining disc comprises the following steps that firstly, the rear axle oil retaining disc blanking-forming composite die without overlapping is mounted on a 100T press machine with a lower ejection cylinder; and secondly, a gas valve of the lower ejection cylinder of the press machine is opened, thus, the lower ejection cylinder operates to the highest stroke position,and an ejection rod of the lower ejection cylinder of a machine tool is driven to move upwards. The lower die part of the die adopts the die rectifier automatically rectifying the die forming gap, a composite die of the upper part of the die is of an embedded structure, the precision of the die is improved, and the service life of the die is prolonged.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, and relates to a manufacturing mold for an oil retaining pan, in particular to a composite mold and a composite process for blanking an oil retaining pan of an automobile drive rear axle without laps-forming and a composite process, especially blanking without laps craft. Background technique [0002] The oil deflecting plate is a disc-shaped part installed in the brake hub of the automobile drive axle and close to the bearing oil seal. Its main function is to prevent dust and foreign matter from entering the bearing oil seal, thereby protecting the normal operation of the bearing. According to the traditional production method, the oil retaining plate is processed in five steps. The process flow is: blanking → blanking → forming → trimming → punching to meet the product design requirements. Due to the large production batch of the oil retaining plate, the traditional production process is us...

AI Technical Summary

Problems solved by technology

Due to the large production batch of the oil retaining plate, the traditional production process is used in this way, the production efficiency is low, and the production time is long

Moreover, in the traditional blanking process, there must be leftover material on both sides of the blanking strip, so that the material utilization rate is not high
