Die for shaping U-shaped part

Abstract

The invention discloses a die for shaping a U-shaped part. The die comprises a base 1, and the base 1 is rotationally connected with a driving wheel 2 and a driven wheel 3 which mesh with each other.The driving wheel 2 is provided with a first poking claw 4, the driven wheel 3 is provided with a second poking claw 5, and the base 1 is provided with a first air cylinder 6 used for driving the first poking claw 4 to rotate. The base 1 is in sliding connection with a first clamping plate 7 and a second clamping plate 8, wherein the first clamping plate 7 is used for abutting against or breakingaway from the lower end of the first poking claw 4, the second clamping plate 8 is used for abutting against or breaking away from the lower end of the second poking claw 5, and the first clamping plate 7 and the second clamping plate 8 are each of a bent structure. The base 1 is in sliding connection with a positioning block 10 used for positioning the U-shaped part 9, and the first clamping plate 7 and the second clamping plate 8 are located on two sides of the positioning block 10. The die for shaping the U-shaped part can improve the precision of the U-shaped part.

Description

technical field [0001] The invention relates to a mold for shaping U-shaped parts. Background technique [0002] In the process of producing and processing U-shaped parts, it is usually realized by stamping dies. It specifically includes an upper mold base and a lower mold base. The lower mold base is provided with a die for accommodating the metal sheet. Through the connection of the guide post, the upper die seat is slidingly connected to the guide post; that is to say, the stamping is completed when the punch is lowered and matched with the die, and then a U-shaped part consistent with the shape of the die is obtained. However, once the punch is pulled out from the die, that is, the punch and the die are parted, after the U-shaped part is taken out, it has a certain springback due to the metal properties of the plate, such as figure 1 shown. In order to improve the precision of the U-shaped piece, it is necessary to reshape the U-shaped piece so that the U-shaped piece...
