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 discloses a trimming assembly for a trimming die, comprising: The first abutting structure is arranged on the upper die; The first abutting structure and the second abutting structure are respectively used for workpiece abutting after the upper die and the lower die are clamped; the cutter is arranged on the upper die and surrounds the first abutting structure; The first abutting structure can move between a first position and a second position along the height direction of the upper die, and moves from the first position to the second position in the process of die assembly of the upper die and the lower die. In some embodiments, a first guide post is disposed at the top of the first abutment structure, and the first abutment structure is slidably connected to the upper die through the first guide post. In some embodiments, a connecting plate is arranged at the top of the first guide post, and the connecting plate is connected with the upper die through a first elastic piece. In some embodiments, the trimming assembly of the trimming die further comprises a buffer member disposed on the lower die corresponding to the cut portion of the workpiece; During the process of clamping the upper die and the lower die, the cut portion of the workpiece is brought into contact with the buffer member. In some embodiments, the cushioning member comprises a ram and a second resilient member; the ejector rod is connected with the lower die in a sliding manner along the height direction of the lower die, and a second elastic piece is arranged between the ejector rod and the lower die; in the process of clamping the upper die and the lower die, the cut part of the workpiece is contacted with the top of the ejector rod. In some embodiments, the upper die and/or the lower die are provided with travel limit bars to limit the down-travel distance of the upper die. In some embodiments, the upper die is provided with a second guide post, and the connecting plate is in sliding fit with the second guide post. In some embodiments, the upper die is provided with relief holes corresponding to the work pieces. In a second aspect, the application also discloses a trimming die comprising the trimming assembly of the trimming die in 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 first abutting structure is located at the first position at the initial stage of die assembly, the first abutting structure is in contact with a station and applies pressure to a workpiece in the process of die assembly of the upper die and the lower die, and as die assembly continues, the first abutting structure enables the surface layer of the workpiece to be plastically compressed before shearing, so that the elasticity of the workpiece is reduced. When the first abutting structure moves to the second position, the cutting edge of the cutter contacts the workpiece and cuts the workpiece, and in the process of cutting the workpiece, the cutter plastically compresses 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.
