In order to overcome the above-mentioned deficiencies in the background technology, the present invention provides a novel door hinge side plate punching and turning die, which can not only improve the machining accuracy, but also solve the problem that the workpiece is difficult to take out.

The technical solution adopted by the utility model to solve the technical problem is a novel door hinge side plate punching and turning die. It includes an upper die base 8, the upper die base 8 is provided with a die handle 12, two hexagon socket screws 16, two positioning pins 15, and two hexagon socket screws 16 are passed between the upper die base 8, the backing plate 10 and the punch fixing plate 9. Connection, there are positioning pins 15 between the upper die base 8, the backing plate 10 and the punch fixing plate 9, the long punch 14 and the short punch 13 are fixed on the punch fixing plate 9, the discharge plate 6 and the upper die The seats 8 are connected by a hexagon socket head screw 11, there is polyester rubber 7 between the stripper plate 6 and the punch fixing plate 9, and the lower die seat 1 and the female die 4 are connected by a hexagon socket head screw 19, and there is also a gap between them. There is a positioning pin 3, and between the upper die base 8 and the lower die base 1, there are also large guide posts 18, small guide posts 2, large guide sleeves 17 and small guide sleeves 5.

Working process and advantages: Fix the upper and lower die bases on the upper and lower surfaces of the press table respectively, put the blank into the die during work, the press works, and the upper die base moves down along the guide post to punch the blank. The hole turns the hole, the upper die seat goes up, and the discharge plate pushes out the workpiece under the action of polyester rubber, which is convenient to take out.
