Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

Referring to fig. 1, a preferred embodiment is shown, which is a battery box bottom plate side punching die, comprising a lower die 1 and an upper die 2, wherein the lower die 1 and the upper die 2 are only set to be the size of one side of a workpiece 3 to be punched, and the workpiece 3 to be punched is subjected to a side punching process. The other side of the workpiece 3 to be punched, which does not need to be punched, can be supported by a self-made bracket.

As shown in fig. 2, a lower die core 11 is arranged on one side of the top of the lower die 1, and a wedge driving block 12 is further arranged on the top of the lower die 1. One side of the lower die core 11 facing the wedge driving block 12 is provided with a lower die edge 13. The shape of the lower die core 11 is a profile modeling of the shape of the side to be punched of the workpiece 3 to be punched, so that the workpiece 3 to be punched is conveniently and stably placed on the lower die core 11, and the size of the lower die core 11 is the size of the side to be punched of the workpiece 3 to be punched. The top of the lower die 1 is further provided with two outer guide posts 14, two lateral force preventing guide plates 15 and two material blocking frames 16.

As shown in fig. 3, an upper die pressing plate 21 matched with the lower die core 11 is arranged on one side of the bottom of the upper die 2, and an upper die wedge 22 matched with the wedge driving block 12 is further slidably arranged at the bottom of the upper die 2. A side punching pressure plate 23 is arranged on one side of the upper die tapered wedge 22 facing the upper die pressure plate 21, an upper die punch 24 is arranged on the side punching pressure plate 23, and the upper die punch 24 is matched with the lower die cutting edge 13. The bottom of the upper die 2 is also provided with two outer guide sleeves 25 and two lateral force preventing guide legs 26. The outer guide sleeves 25 correspond to and match the outer guide posts 14 one by one, and the lateral force preventing guide legs 26 correspond to and match the lateral force preventing guide plates 15 one by one.

The process for side punching using this embodiment includes the steps of:

(a) the upper die 2 and the lower die 1 are fixedly installed on a punching machine, then the workpiece 3 to be punched is preliminarily positioned through the material blocking frame 16, one side, to be punched, of the workpiece 3 to be punched is placed on the lower die core 11 of the lower die 1, and the position, to be punched, of the workpiece 3 to be punched is aligned 13 to the lower die knife edge. And supporting the other side of the workpiece 3 to be punched, which does not need to be punched, by a self-made bracket.

(b) And starting the punch press, driving the upper die 2 to move downwards by the punch press, respectively inserting the outer guide posts 14 into the corresponding outer guide sleeves 25, and respectively contacting the lateral force preventing guide plates 15 with the corresponding lateral force preventing guide legs 26 to play a role in guiding the die. Thereafter, upper die cam 22 contacts cam drive block 12, and upper die cam 22 starts moving in the direction of lower die edge 13 along cam drive block 12 while moving downward.

(c) The upper die 2 continues to move downwards, the upper die pressing plate 21 gradually approaches the lower die core 11 and presses the workpiece 3 to be punched, and the side punching pressing plate 23 also gradually approaches the side surface of the lower die core 11 and presses the side surface of the workpiece 3 to be punched.

(d) The upper die 2 continues to move downwards, and the upper die wedge 22 also continues to move towards the lower die core 11 until the upper die punch 24 enters the lower die cutting edge 13, so that side punching is completed.

(e) The punch press drives the upper die 2 to move upward and return to the original position.

In the embodiment, the size of the die is developed into the size of one side to be punched of the workpiece 3 to be punched, the size of the die can be shortened from the existing minimum length of 2100mm to 740mm, the external dimension of the die is greatly reduced, the development cost of the die is reduced, and as the external dimension of the die is reduced, the tonnage of a machine platform for required production is reduced from the conventional 300 tons to 160 tons, the occupied space of the machine platform is reduced, the price is reduced, and the production cost is also reduced.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
