Abstract

The invention discloses a drawing punching compound die. The drawing punching compound die comprises upper die and lower die which are oppositely installed upwards and downwards. The lower die is fixedly connected with a hydraulic device. A forming plate matched with the upper die is installed between the upper die and the lower die. The upper die and the forming plate are respectively connected with a driving device of the hydraulic device. The upper die is provided with a concave installing hole. The forming plate is provided with a second through hole corresponding to the installing hole. A forming block is slidably installed in the installing hole. The second through hole is internally and slidably provided with a drawing punch matched with the forming block. The drawing punch is supported on the lower die by a first spring support component vertically supported on the lower die. The end faces of the upper die and the forming block form an upper forming plane for forming a cylinder component. The end faces of the forming plate and the drawing punch form a lower forming plane mated with the upper forming plane for forming the cylinder component. The lower die is vertically provided with a plurality of blanking punches. The drawing punch is slidably installed on the blanking punches. The forming block is provided with a plurality of blanking holes corresponding to a plurality of the blanking punches. The lower die is slidably provided with an active base plate.

Description

technical field [0001] The invention relates to the field of composite processing of metal plates, in particular to a composite die for drawing and punching. Background technique [0002] The structure of the cylindrical part is shown in the attached picture figure 1 and figure 2 As shown, the diameter of the cylinder is Φ150, the flange diameter of the inner hole at the bottom of the cylinder is Φ110, and there are 9 small holes of Φ10 distributed along the circumference of the cylinder bottom. In the prior art, processing figure 1 and figure 2 For the cylindrical parts of the structure shown, according to the usual process route, the sheet material needs to be processed through three processes of drawing, flanging, and punching, so three sets of molds are required to complete the corresponding processing, the process route is cumbersome, and the processing efficiency is low. Processing costs are high. Contents of the invention [0003] The invention provides a dee...
