The invention discloses a 180-degree edge folding high-efficiency machining method and device for an automobile engine bin cover. The method and the device are used for carrying out edge folding machining on a bin cover workpiece which is machined by a drawing process, an edge trimming process and a punching process. The method comprises a pre-flanging work procedure carried out by adopting a pre-flanging device and an edge folding work procedure carried out by adopting an edge folding device; in the pre-flanging work procedure, the edge of a portion to be folded of the bin cover workpiece isbent, and the edge of the bent portion of the bin cover workpiece is preflanged according to a preset angle; and in the edge folding work procedure, the pre-flanged portion of the bin cover workpieceis subjected to edge folding. 180-degree edge folding high-efficiency machining of the automobile engine bin cover can be realized without expensive special equipment and tools, the die structure is simple, maintenance is easy, the edge folding size can be ensured, and the problems that an existing 180-degree edge folding tool for the automobile engine bin cover is high in investment, a special machining place is needed, and the equipment and tool maintenance cost is high are solved.
Description
technical field [0001] The invention relates to the technology for realizing the structural realization of the undulating surface and the irregular overlapping of the contour of the product, in particular to an efficient processing method and a processing device for the 180-degree overlapping of the automobile engine compartment cover. Background technique [0002] With the rapid development of the automobile industry, more and more automobile models are listed at home and abroad every year, and consumers have higher requirements for the cost performance of automobiles. Therefore, the automobile industry has higher and higher requirements for product cost control, and all links must be low-cost. High quality is the goal to produce and manufacture products. At present, the lapping processing of the automobile engine compartment cover, especially the 180-degree lapping processing, is mostly realized by robots or manual special planes. The investment in tooling is large, the la...
