Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1, the utility model provides a high-precision blanking and punching die with an internal guide, which comprises a lower die and an upper die, wherein the lower die is provided with a lower die holder 1 and a pressure plate 2, two sides of the lower die holder 1 are respectively provided with an external guide post 4, and the pressure plate 2 is provided with a male die 3 and an internal guide post 5; an upper die base 6 and a stripper 7 are arranged on the upper die, outer guide sleeves 10 are respectively arranged on two sides of the upper die base 6, and a female die 8 and an inner guide sleeve 9 are arranged on the stripper 7.
Furthermore, the lower die further comprises a positioning pin 11 arranged on the pressure plate 2.
Further, inner guide posts 5 are arranged at four corners of the material pressing plate 2 on the lower die; the inner guide sleeves 9 are arranged at four corners of the stripper plate 7 on the upper die.
Further, an outer guide post 4 on the lower die corresponds to an outer guide sleeve 10 on the upper die up and down; the inner guide posts 5 on the lower die and the inner guide sleeves 9 on the upper die are in one-to-one correspondence up and down.
Furthermore, the shape and size of the male die 3 on the lower die are consistent with those of the female die 8 on the upper die, and the male die and the female die are corresponding up and down.
The working process is as follows: the strip materials are fed from front to back along the positioning pin 11 on the pressure plate 2, the outer guide sleeve 10 arranged on the upper die base is contacted with the outer guide post 4 arranged on the lower die base to work when the machine tool moves downwards, first guide is realized, the inner guide post 5 arranged on the lower die base and the inner guide sleeve 9 arranged on the upper die base work when the machine tool continues to move downwards to press the pressure plate 2, the plate materials and the stripper 7 are contacted, second guide is realized, the blanking precision of the die is improved, blanking work is realized when the machine tool continues to move downwards to be arranged on the male die 3 of the lower die and the female die 8 arranged on the upper die, and therefore the blanking and punching process is realized, and the machine tool continues to circulate next to realize production of second parts.
The present invention is not limited to the above-mentioned best mode, and any other products similar or identical to the present invention, which can be obtained by anyone under the teaching of the present invention, all fall within the protection scope of the present invention.
