Fig. 3 is an enlarged structural view of a portion a in fig. 2.

In the figure: 1. the device comprises an upper die base, 2, an upper backing plate, 3, an upper clamping plate, 4, a stop plate, 5, a stripper plate, 6, a lower die plate, 7, a lower backing plate, 8, a lower die base, 9, a lower backing pin, 10, a lower supporting plate, 11, an upper slotting tool, 12, a lateral piercing punch, 13, a piercing female die, 14, a reset spring, 15, a lateral piercing punch fixing seat, 16, a lateral piercing punch fixing pin, 17, a material supporting slide block ejection device, 18 and a V-shaped groove.

Detailed Description

The utility model discloses a mould structure is punctureed to side direction is shown in fig. 1 and fig. 2, including upper die base 1 and die

holder

8, 1 downside of upper die base installs

upper padding plate

2, 2 downside installation punch shanks 3 of upper padding plate, 3 downside installation backstop boards 4 of punch shang and take off flitch 5, 8 upside installation lower bolster of die

holder

7, 7 upside installation lower bolster 6 of lower bolster, install slotting tool 11 on the punch shang 3, punch fixing base 15 is punctureed in installation side direction on the lower bolster 7, punch fixing base 15 is punctured through 16 installation side directions of side direction puncture punch fixing pin installation side directions on the side direction puncture drift 12, the side direction puncture drift 12 is located the outside that slotting tool 11 corresponds the position, it punctures die 13 to lie in the installation in the side direction puncture drift 12 outside on the lower bolster 6.

The arc surface of the punch is contacted with the V-shaped groove 18 of the fixed seat, so that the side piercing punch 12 can swing left and right by taking the punch fixing pin 16 as the center of a circle; simultaneously, a piercing female die 13 is arranged on the lower die; when the die is operated, the upper slotting tool 11 interacts with the inclined surface of the lateral piercing punch 12, the lateral piercing punch 12 swings towards the piercing direction of the inner wall of the product, and the product is extruded until the piercing process is finished.
