Impact cracking process and equipment

Abstract

The invention provides an impact cracking process and equipment. The impact cracking equipment comprises a device frame body, a thrust mechanism, a pressing and fixing reducer housing mechanism, a straightening reducer housing mechanism and a conveying and positioning reducer housing mechanism, the thrust mechanism comprises a gear transmission device, a driving device and an impact hammer, the driving device is used for driving the gear transmission device to rotate, and the impact hammer swings downwards to knock a metal part under the action of self gravity after being lifted upwards along with rotation of the gear transmission device; the pressing and fixing reducer housing mechanism comprises a second lifting device and I-shaped iron, and the second lifting device lifts to press the I-shaped iron to abut against the metal part; the straightening reducer housing mechanism comprises a U-shaped rod, and the U-shaped rod rotates relative to the device frame body to press the metal part; and the conveying and positioning reducer housing mechanism is used for placing metal part. The impact cracking process and equipment have the advantages that a bearing seat can be subjected to brittle fracture at a stress groove by applying an impact load to a bearing seat part, and the accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of metal cracking, in particular to a process and equipment for impact cracking. Background technique [0002] At present, the reducer casing is an important part of the automobile transmission system. At present, the differential bearing seat of the reducer casing is mostly split, that is, half of the differential bearing seat and the reducer casing are cast as one, and the other half of the differential bearing seat Separately cast and processed separately, the reducer housing and the other half of the bearing housing are connected together by bolts and positioning pins. The current process in the industry is to process the mating surfaces of the two workpieces flat by machine tools, drill threaded holes and positioning pin holes, and connect them together through bolts and positioning pins. Under this process scheme, the parts are prone to deformation and displacement under the action of the axial force ...

AI Technical Summary

Problems solved by technology

Under this process scheme, the parts are prone to deformation and displacement under the action of the axial force on both sides generated during the driving process of the vehicle, which affects the stability of the entire bridge transmission

[0003] In the prior art, the bearing seat of the middle and rear axle reducer is often cracked through the automobile connecting rod expansion process. The cracking method is to use pressure to burst from the inner ring of the bearing seat to form an irregular fracture surface, but the cracking method does not Inaccurate, unable to make an accurate judgment on the place that needs to be cracked, thus affecting the later work
