U-shaped plastic manipulator

Abstract

The invention discloses a U-shaped part shaping mechanical arm. The U-shaped part shaping mechanical arm comprises a base. The base is rotationally connected with a driving wheel and a driven wheel which are engaged with each other. The driving wheel is provided with a first stirring pawl, and the driven wheel is provided with a second stirring pawl. The base is provided with a first air cylinderfor driving the first stirring pawl to rotate. The base is in sliding connection with a first clamping plate and a second clamping plate, wherein the first clamping plate is used for tightly abuttingagainst or disengaging from the lower end portion of the first stirring pawl, and a second clamping plate used for tightly abutting against or disengaging from the lower end portion of the second stirring pawl. The base is in sliding connection with a positioning block for positioning a U-shaped part, and the first clamping plate and the second clamping plate are located on the two sides of the positioning block correspondingly. The base is provided with a guide column, and the positioning block, the first clamping plate and the second clamping plate are in sliding connection to the guide column at the same time. The U-shaped part shaping mechanical arm capable of improving the U-shaped part precision is provided.

Description

technical field [0001] The invention relates to a U-shaped piece plastic manipulator. 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 pi...
