Technical Field

The application relates to the field of bush machining and forming, in particular to a shaping machine for machining a bush.

Background

The bush is a ring sleeve which plays a role of a liner and is widely applied to sliding parts of various machines, such as automobiles, motorcycles, printing machines, textile machines, agriculture and forestry machines and the like. In moving parts, long-term friction causes wear of parts, which must be replaced when the clearance between the shaft and the bore is worn to a certain extent, and bushings are installed between the shaft and the bore, thereby reducing wear of the shaft and the shaft seat.

The copper bush is generally formed by rolling a rectangular sheet-shaped copper blank, and after the bush is formed by punching and rolling, the inner circle of the bush needs to be shaped by a shaping machine, so that the cylindricity precision of the bush is improved. In the shaping process, the bushing is fixed in the shaping die, the shaping shaft of the shaping machine reciprocates along the axis of the bushing, the shaping shaft is inserted into the bushing, the outer peripheral surface of the shaping shaft abuts against the inner peripheral surface of the bushing, and the outer peripheral surface of the bushing abuts against the shaping die under the expansion action of the shaping shaft, so that the shaping process of the bushing is completed.

In view of the above-mentioned related technologies, the inventor believes that metal debris remained in the previous processing process may adhere to the inner wall of the liner before the liner is shaped, and in general, a worker needs to wipe off the metal debris by using a rag, so that the defects of large workload and dependence on manual work exist.
