Description

Trimming assembly of trimming die and trimming die Technical Field The utility model relates to the technical field of trimming dies, in particular to a trimming assembly of a trimming die and the trimming die. Background The trimming die is a special tool for removing redundant edge materials after the workpiece is molded, is generally composed of an upper die and a lower die which are in precise fit, realizes high-efficiency shearing through the power of a press machine, can precisely control a blanking gap to ensure the quality of a cut, and is suitable for finishing and processing of automobile covering parts, forging burrs or injection molding burrs. The trimming assembly of the trimming die is used for shearing redundant edge materials of a workpiece, and in the related art, when the workpiece is a radiator, the upper die is easy to cause fin damage of the radiator in the process of clamping the upper die with the lower die. Disclosure of utility model The application discloses a trimming assembly of a trimming die and the trimming die, which are used for solving the technical problem that workpieces are easily damaged in the process of trimming the workpieces in the related technology. In order to solve the problems, the utility model adopts the following technical scheme: In a first aspect, the present application discloses a trimming assembly for a trimming die, comprising: The first abutting structure is arranged on the upper die and is provided with a cavity for accommodating a workpiece; the second abutting structure is arranged on the lower die and used for placing a workpiece; The cutter is arranged on the upper die and surrounds the first abutting structure; the deformation piece is arranged in the cavity and is provided with a gap with the inner wall of the cavity; and in the process of clamping the upper die and the lower die, the top of the workpiece is contacted with the deformation piece so as to deform the deformation piece and fill the gap of the workpiece. In some aspects, the deforming member includes a deforming portion and a mounting block; the installation piece can be dismantled and set up in the die cavity, and deformation portion sets up in the bottom of installation piece to have the clearance with the inner wall of die cavity between. In some aspects, the second abutment structure is provided with a positioning portion corresponding to the geometric feature of the workpiece to position the workpiece in the position of the second abutment structure. In some aspects, the first abutment structure is slidably connected to the upper die along a height direction of the upper die and is movable between a first position and a second position; the first abutting structure moves from the first position to the second position in the process of clamping the upper die and the lower die.
