Máquina brochadora de tapas de cojinetes

The connecting rod special broaching machine is mainly used for broaching the connecting rod joint surface, tooth surface, convex, groove, weight removal surface, semi-arc and other positions. The positioning of the rod mainly adopts the method of one pin on both sides, and the cover adopts the surface positioning and The device in the swing arm alignment is positioned. The fixture is a sub-female fixture structure, using hydraulic control, and can achieve multi-station broaching at the same time, high work efficiency.

The special broaching machine for the main bearing cover is mainly used for processing the main bearing cover on the cylinder body. The machine tool is a single slide plate or a double slide plate structure. Within the nominal pulling force and the length of the slide plate stroke, the two large planes of the bearing cover can be broaching. The joint surface, the arc surface and the bolt surface realize multi-station simultaneous processing, which greatly improves the work efficiency.

This machine adopts the hydraulic system transmission, the work is stable, can carry on the stepless speed regulation. And there are a variety of insurance devices, after years of experience accumulation, in the tool design, the machine on the broach is the use of combined alloy broach, the broaching method is the front of the rough cutting, the rear of the fine cutting, to ensure the surface roughness of the workpiece requirements. A tool protection device is installed in the front of the broach. When the broaching amount is greater than the allowable amount of the tool, the machine tool cannot broach. The machining position is also equipped with an air-tight detection device, which can effectively control the machining risk of the machine tool.
