Description

Die-cut module and die-cut frock Technical Field The invention belongs to the technical field of machinery, and particularly relates to a punching module and a punching tool. Background It is known that the exterior water cut product is the most common sealing element in the field of automobile production and preparation, and has a certain appearance decoration effect and good sealing property. The existing external water cutting product adopts a preparation process that the sawed semi-finished product is mainly used for punching and cutting, so that the end head of the external water cutting product is processed and punched with required angles and notches, and the notches and the angles are mainly used for meeting the requirements of assembling buckles, end head injection molding and whole vehicle assembly. At present, the punching of the outer water cutting end head needs to punch two inner lips and two outer lips, and the outer water cutting end head is generally punched by manually cutting the edge position by a blade, then inserting a corresponding punching die, controlling the edge cutting position of the outer water cutting end head to be difficult, and matching the non-uniform position of die punching after cutting, so that the outer water cutting product is scrapped after cutting or reworked manually, the production efficiency is influenced, and the production cost is greatly increased. Disclosure of Invention The invention aims to solve the technical problem of providing a novel punching module to solve the problems that the existing manual knife edge cutting position is difficult to control and the cutting position is inconsistent in matching with the punching position of a die again after cutting. In order to solve the technical problems, the invention adopts the technical scheme that the punching module comprises a bottom plate, and a punching assembly, a guide assembly, a first limiting piece and a second limiting piece which are arranged on the bottom plate; the bottom end of the punching assembly is connected with the bottom plate through an elastic piece, and the first limiting piece is used for blocking the top end of the punching assembly so as to limit the maximum height of the punching assembly in the vertical direction; The guide assembly is used for guiding the feeding direction of the external water cutter, pre-cutting the external water cutter to enable the punching assembly to punch the pre-cut opening of the external water cutter along the feeding direction, and the second limiting piece is used for blocking the external water cutter to limit the maximum feeding travel of the external water cutter in the feeding direction. In the prior art, the cutting edge is usually cut by a blade manually before the external water is cut, and then the external water is inserted into a corresponding cutting die to be cut. Because of the manual incision, the control of the incision position of the incision is difficult, and the problem of mismatch with the punching position of the punching die easily occurs after the incision is finished. Therefore, in the above technical scheme of the present invention, the inventor designs a new punching die, which has a new design on the structure of the punching die, so as to set a guide component on the punching die, and guide the feeding direction of the external water cut by using the guide component, so that when the external water cut is fed into the punching die, the lip of the external water cut can be pre-cut by using the guide component, once the external water cut is fed in place and blocked by the second limiting piece, the user can control the punching component to punch the pre-cut position of the external water cut along the feeding direction, thereby ensuring that the punching position of the punching component is consistent with the pre-cut position of the guide component. Therefore, the die-cutting die designed by the invention can change the original manual blade cutting into the external water cutting to insert the lip edge of the external water cutting during feeding, and die-cut after feeding in place, can ensure that the die-cutting position is consistent with the cutting position, does not need to manually pre-cut, can greatly improve the production efficiency and improve the yield of products. Further, in the die-cutting module according to the present invention, the guide assembly includes a first guide member and a second guide member, the first guide member includes a guide support block and a guide block, one end of the guide support block is connected to the bottom plate, the other end of the guide support block is detachably connected to the guide block, and the height of the guide block in the vertical direction is higher than that of the second guide member. Further, in the punching module, at least one roller is arranged on the guide block, the second guide piece comprises a protruding portion extending along the feeding dire
