Rear hub package machining device of minibus

Abstract

The invention discloses a rear hub package machining device of a minibus. The rear hub package machining device comprises an upper die base, a lower die base, a pressing device, an upper die cutter, a lower die cutter, elastic devices, punches, guide columns and stocky blocks. The top face of the lower die base is of a curved surface structure capable of carrying out supporting positioning on a workpiece. A blade part is arranged at the position, corresponding to a to-be-trimmed part of the workpiece, of the top face of the lower die base. The pressing device is in sliding connection to the upper die base in the vertical direction in a single-freedom-degree manner, and the workpiece is tightly pressed between the lower die base and the top face of the lower die cutter. The elastic devices are arranged between the upper die base and the pressing device. Wheels in rolling fit with the inner walls of guiding sleeves are arranged on the side walls of the guide columns. According to the rear hub package machining device of the minibus, trimming and punching of a rear hub package of the minibus can be finished at a time. Compared with the prior art, a machining procedure is omitted, the product quality can be guaranteed, the productivity is improved, and the production cost is reduced; and meanwhile the equipment fault rate can be reduced, and the maintaining cost is saved.

Description

technical field [0001] The invention relates to a mechanical processing mold, in particular to a processing device for a rear wheel hub package of a van Background technique [0002] The rear wheel hub package of minivan is a metal sheet shell part formed by cold working, with multiple connecting holes and complex curved surface structure and edge contour. In the prior art, the production of rear hub package of minivan is usually based on sheet metal. Raw materials are completed by deep drawing, edge trimming, punching and other processing procedures. First, the metal sheet is drawn and formed, and then the formed blank is processed by trimming and punching. The processing procedures and the required molds are relatively Many, the cumulative processing error is large, the product quality is unstable, the qualified rate is low, and the production cycle is long and the cost is high; at the same time, the guiding structure between the upper die and the lower die of the stamping...

[0002] The rear wheel hub package of minivan is a sheet metal shell part formed by cold working, which has multiple connection holes and complex curved surface structure and edge contour. In the prior art, the production of rear hub package of minivan is usually based on sheet metal. Raw materials are completed by deep drawing, trimming, punching and other processing procedures. First, the metal sheet is drawn and formed, and then the formed blank is processed by trimming and punching. The processing procedures and the required molds are relatively large. Many, the cumulative processing error is large, the product quality is unstable, the pass rate is low, and the production cycle is long and the cost is high. The wear is serious and the failure rate is high, which affects the smooth progress of processing and leads to an increase in maintenance costs
