Abstract

The invention discloses a punching die tolerance absorption flexible structure, and relates to the technical field of dies. The punching die tolerance absorption flexible structure comprises a support, a punching assembly and a flexible assembly; the punching assembly comprises a punching punch used for punching a product and a driving source used for driving the punching punch to move; the flexible assembly is arranged between the support and the punching assembly, the flexible assembly comprises a plurality of first elastic pieces, the punching assembly is installed on the support through the first elastic pieces, the flexible assembly further comprises a floating block, the lower ends of the first elastic pieces are connected with the support, the upper ends of the first elastic piecesare connected with the floating block, and the punching assembly is installed on the floating block; and the floating block is provided with a plurality of limiting bolts used for adjusting the floating stroke of the floating block, and the limiting bolts penetrate through the floating block and then are connected to the support. According to the punching die tolerance absorption flexible structure, tolerance fluctuation of the radian of the product can be absorbed, flexible compatibility of different radian tolerances is achieved, the radian of the product is basically kept unchanged before and after punching, and therefore the problem that the radian of the punched product is out of tolerance due to the change of the bending radian of the product is solved.

Description

technical field [0001] The invention relates to the field of die technology, in particular to a punching die tolerance absorbing flexible structure. Background technique [0002] The front door and window frame of a car generally includes four parts: A-pillar sub-assembly, B-pillar sub-assembly, front door reinforcement plate and front door upper strip, the production process of front door upper strip: rolling → bending → punching → sawing → welding, That is, after the semi-finished product is obtained by rolling bending, it is bent by the bending die, and then the gap of the semi-finished product is punched out by punching, and then sawing is performed to cut off the position reserved for the clamping chuck to obtain the front upper product, and finally Then weld the assembly. Rolling is to obtain a straight strip with a required cross-section through the formation of rollers. Since it is left and right, the length of the straight strip is the length of the left and right ...
