Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, and not all embodiments.

Example (b):

referring to fig. 1-4, the present embodiment is a clutch transmission plate fine-cutting forming structure, which includes a lower clamp plate 1, at least one set of female die insert blocks 11 embedded in the lower clamp plate 1 and symmetrically arranged at intervals, and a trimming punch 2 disposed above the lower clamp plate 1 and matched with the female die insert blocks 11 in a matched mold closing and inserting manner; the surface of the lower clamping plate 1 supports a material belt 12 which can be movably arranged, the punching section size of the trimming punch 2 is larger than the cross section size of the material belt 12, and the punching section of the trimming punch 2 forms the edge of a product 13.

This embodiment product 13 is clutch drive plate, and product 13 is cuboid sheet structure, and the both ends of product 13 are equipped with a set of chamfer 14 respectively.

Edge cutting drift 2 designs according to product 13's edge demand for edge cutting drift 2's the section of dashing can accurate shaping product 13 edge structure, and edge cutting drift 2 is L type structure in this embodiment, and edge cutting drift 2's inboard is equipped with the inclined plane 21 of bending that is used for shaping product 13 chamfer 14 position, and edge cutting drift 2's the outside is flat face 22, and edge cutting drift 2's the outside dashes cuts off material area 12. The split type trimming punch 2 independently breaks one section of the material belt 12 to form a product 13, and avoids the waste of excessive materials caused by the traditional blanking along the circumferential appearance of the product 13.

The concave die insert block 11 is internally provided with a groove 15 for accommodating the trimming punch 2, and trimming waste of the product 13 falls into the groove 15 for waste discharge treatment. The surface of the female die insert 11 is flush with the surface of the lower clamping plate 1.
