[0002] With the development of the manufacturing industry, people have put forward higher requirements for the shape of cars, which is a big challenge for mold manufacturing. The technical requirements stipulate that when the trimming angle is greater than 15 degrees, the wedge punching should be used. However, in order to reduce the number of molds and reduce manufacturing costs, in the mold design and manufacturing process, sometimes it is still necessary to perform punching when the angle is out of tolerance, and at this time the side impact force will affect the punching effect.

[0003] Based on the above situation, the present invention proposes a die for balancing the lateral force of punching, which can effectively solve the above problems. Summary of the invention

The positional relationship described in the drawings is only for exemplary description and cannot be understood as a limitation on this patent.

[0025] Embodiment 1:

[0026] like Figures 1 to 9 As shown, a mold for balancing the lateral force of punching comprises an upper mold 1 and a lower mold 2 which are interlocked with each other; a plurality of tool fixing seats 11 are provided in the upper mold 1; a tool head assembly 12 is provided on the tool fixing seat 11; a punching groove 21 is provided on the lower mold 2 corresponding to the tool head assembly 12; the tool head assembly 12 comprises a tool head base 121 fixed on the tool fixing seat 11; a tool head mounting seat 122 is provided on the tool head base 121; a tool head 123 is embedded in the tool head mounting seat 122; the tool head 123 has a first blade portion 1231 and a second blade portion 1232; the first blade portions 1231 are connected by a tool head transition portion 1233; the tool head mounting seat 122 comprises a first side plate 1221 close to the first blade portion 1231 and a second side plate 1222 away from the first blade portion 1231; the position of the first side plate 1221 in the vertical direction is higher than the position of the second side plate 1222 in the vertical direction.

[0027] The present invention punches a workpiece through the first blade portion 1231, the second blade portion 1232 and the blade transition portion 1233 of the blade assembly 12, thereby ensuring a better punching effect; the blade mounting seat 122 strengthens the fixing effect and supporting effect of the blade 123, thereby preventing the blade 123 from shifting and rotating during punching, thereby ensuring a better punching effect; the first side plate 1221 strengthens the support capacity on one side of the blade 123, thereby preventing the blade 123 from shifting during punching, thereby ensuring a better punching effect.

[0028] The cutter head 123 is fixed to the cutter head mounting seat 122 by means of bolts 124 .

[0029] Furthermore, in another embodiment, an extension plate 1223 is further provided on the top of the first side plate 1221 .

[0030] The extension plate can better strengthen the support capability of one side of the cutter head 123, prevent the cutter head 123 from deflecting during punching, and ensure a better punching effect.

[0031] Furthermore, in another embodiment, a stopper 111 is provided at the top of the tool fixing seat 11 close to the first blade portion 1231 , and a stopper groove 1211 is provided at the bottom of the tool head base 121 close to the first blade portion 1231 .

[0032] The stop block 111 and the stop groove 1211 can not only play a limiting role, so that the tool head assembly 12 can be better fixed on the tool fixing seat 11; but also enhance the single-sided support capacity of the tool head assembly 12, prevent the tool head assembly 12 from shifting during punching, and ensure a better punching effect.

[0033] Furthermore, in another embodiment, the upper die 1 is further provided with a positioning seat 13 sleeved on the cutter head assembly 12 .

[0034] The positioning seat 13 provides a good support for the cutter head assembly 12 , thereby preventing the cutter head assembly 12 from deviating during punching and ensuring a good punching effect.

[0035] Furthermore, in another embodiment, the vertical distance from the top of the first blade 1231 to the positioning seat 13 is a, a=7-10 mm; the vertical distance from the top of the second blade 1232 to the positioning seat 13 is b, b=2-4 mm.

[0036] The length of the first blade 1231 exposed from the positioning seat 13 is greater than the length of the second blade exposed from the positioning seat 13. During punching, the first blade 1231 will shear in advance and act as a piercing knife to reduce the punching force required later, thereby reducing the lateral force. When the second blade 1232 starts to cut in, the first blade 1231 has already cut into the workpiece, and the cutting edge of the first blade 1231 and the punching groove 21 are used to offset the lateral force of the second blade 1232 and the tool head transition portion 1233 when cutting in.

[0037] Furthermore, in another embodiment, the vertical distance from the top of the first blade 1231 to the positioning seat 13 is a, a=8 mm; the vertical distance from the top of the second blade 1232 to the positioning seat 13 is b, b=3 mm.

[0038] According to the description and drawings of the present invention, those skilled in the art can easily manufacture or use the die for balancing the lateral force of punching of the present invention, and can produce the positive effects described in the present invention.
