Description

Trimming assembly of trimming die and trimming die Technical Field The utility model relates to the technical field of 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 the workpiece, and in the related art, the workpiece is easy to deform burrs or cuts due to rebound. 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 burrs or cuts are easy to deform due to cutting 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 provides a trimming assembly for a trimming die, comprising: The first abutting structure is arranged on the upper die; After the lower die and the upper die are clamped, the first abutting structure and the second abutting structure are respectively in workpiece abutting connection; the cutting piece is arranged on the lower die and can move between a first position and a second position along the height direction of the lower die; And in the process of clamping the lower die and the upper die, the cutting piece moves from the first position to the second position. In some aspects, the cutting member comprises a cutter structure and a connecting block; The connecting block and the lower die are in sliding connection along the height direction of the lower die, the cutter structure is arranged on the connecting block, and the top of the cutter structure is provided with a cutting edge. In some schemes, a first guide post is arranged at the bottom of the connecting block, and the connecting block is in sliding connection with the lower die through the first guide post; and/or the connecting block is connected with the lower die through the first elastic piece. In some aspects, the first abutting structure and the second abutting structure are respectively multiple, and form multiple stations for abutting against the workpiece, and the multiple stations are arranged in multiple rows; At least one cutting piece is arranged between any two adjacent rows of stations. In some aspects, the first abutting structure is slidably connected with the upper die along a height direction of the upper die, and a bottom of the first abutting structure exceeds a bottom of the upper die. In some aspects, a second guide post is arranged at the top of the first abutting structure, and the first abutting structure is in sliding connection with the upper die through the second guide post. In some schemes, a connecting plate is arranged at the top of the second guide post, and the connecting plate is connected with the upper die through a second elastic piece. In some aspects, the upper die is provided with a third guide post, and the connecting plate is in sliding fit with the third guide post; And/or the bottom of the upper die and/or the top of the lower die is/are provided with a travel limit rod so as to limit the descending distance of the upper die. In some schemes, the bottom of the connecting plate is provided with an auxiliary rod; The auxiliary rod is abutted against the top of the lower die after the upper die and the lower die are clamped, or the top of the lower die is provided with a bulge, and the auxiliary rod is abutted against the bulge after the upper die and the lower die are clamped. In a second aspect, the present application discloses a trimming die comprising the trimming assembly of the trimming die of the first aspect. The technical scheme adopted by the utility model can achieve the following beneficial effects: According to the trimming assembly of the trimming die, the initial die-closing cutting piece is located at the first position (high position), so that the first abutting structure and the second abutting structure are ensured to be in contact with the workpiece preferentially to apply pressure to the workpiece, the surface layer of the workpiece is subjected to plastic compression before shearing, and the elasticity of the workpiece is reduced. And in the process of shearing the workpiece, the cutting piece is subjected to plastic compression due to the surface layer of the workpiece, so that burrs and notch deformation generated in the cutting process of the workpiece are reduced, and the notch quality is obviously improved.
