A process and equipment for shock cracking

Abstract

The invention proposes a process and equipment for impact cracking, which includes a device frame, a punching mechanism, a pressing and fixing shell reducing mechanism, a straightening shell reducing mechanism, and a conveying and positioning shell reducing mechanism; the punching mechanism includes a gear transmission device, a drive device and impact hammer, the driving device is used to drive the gear transmission to rotate, the impact hammer is lifted up with the rotation of the gear transmission, and then swings down to strike the metal parts under the action of its own gravity; The shell mechanism includes a second lifting device and an I-shaped iron. The second lifting device presses the I-shaped iron to abut against the metal parts through lifting and lowering; The frame body rotates to compress the metal parts; the conveying positioning shell reducing mechanism is used to place the metal parts, thereby, the present invention has the ability to realize the brittle fracture of the bearing seat from the stress groove by applying an impact load on the bearing seat, which improves the The advantage of precision.

Description

technical field [0001] The invention belongs to the technical field of metal cracking, and particularly relates to a process and equipment for impact cracking. Background technique [0002] At present, the reducer shell is an important part in the automobile transmission system. At present, the differential bearing seat of the reducer shell is mostly split, that is, half of the differential bearing seat and the reducer shell are cast as one, and the other half of the differential bearing seat is cast as one. Cast and machined separately, the reducer housing and the other half of the bearing seat are connected together by bolts and locating pins. The current technology in the industry is to flatten the mating surfaces of the two workpieces by machine tools, drill threaded holes and locating pin holes, and connect them together with bolts and locating pins. Under this process scheme, the parts are easily deformed and displaced under the action of the axial force on both sides...

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
