Plate punching die capable of preventing burrs from appearing

Abstract

The invention discloses a plate punching die capable of preventing burrs from appearing. The plate punching die comprises a puncher pin. A plate is arranged at the bottom of the puncher pin. A blanking die is arranged on the side face of the plate. The bottom of the blanking die is in sliding connection with a supporting block. An extrusion rod is arranged on the side face of the blanking die in apenetrating manner. A pressure sensitive switch is fixedly connected to the side, close to the die core, of the extrusion rod. A centrifugal rod is in sliding connection in a centrifugal pipe. A triangular scraping rod is rotationally connected to the side, away from the axis, of the centrifugal rod. The side face of the distance adjusting shaft is fixedly connected with an adjusting pipe. An impact rod is in sliding connection in the adjusting pipe. A lever is arranged on the side, away from the axis, of the adjusting shaft. The top of the lever is fixedly connected with a one-way clamping plate. According to the plate punching die capable of preventing burrs from appearing, through cooperative use of the pressure sensitive switch and the triangular scraping rod, the effect that when a gap appears between the puncher pin and the blanking die, appearing burrs are removed before cooling is achieved.

Description

technical field [0001] The invention relates to the technical field of dies, in particular to a plate punching die which can prevent burrs from appearing. Background technique [0002] Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping, etc. to obtain the required products. In short, molds are used to make shaped items Tool, this kind of tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. [0003] When using the punching die, due to the long-term use of the punching die, the inner hole of the blanking die will expand, resulting in a gap with the inner hole of the blanking die. When punching a plate, the existence of this gap It will cause burrs to appear on the lower edge of the plate punching. If the pl...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a plate punching die that can prevent burrs from appearing. It has the advantages of clearing the burrs before cooling when there is a gap between the punch and the blanking die, and solves the problem of existing problems. When there is a gap between the punch and the blanking die of the punching die, the problem that the burr on the lower edge of the punching part of the sheet cannot be removed in time
