Flanging die with automatic jacking mechanism

Abstract

The invention discloses a flanging die with an automatic jacking mechanism. The flanging die comprises a machine frame, a platen, an upper die plate, an upper die, a punch block, a lower die and a lower die plate. The machine frame is provided with the platen, the platen is provided with the lower die plate, the lower die plate is provided with the lower die where a workpiece is placed, the upperdie plate and the upper die are arranged over the lower die, the upper die plate and the upper die are fixed through a fastening screw, the upper die is provided with the punching block for flanging the workpiece, the bottom of the punching block is provided with a protrusion, the protrusion is arranged at the end, away from the workpiece, of the punching block, and the lower die plate is furtherprovided with the automatic jacking mechanism for automatically jacking the workpiece. The flanging die has the beneficial effects that after flanging is completed for the workpiece, the workpiece canbe jacked automatically through a jacking rod, manual material taking is not needed, the condition that a piston is moved upwards suddenly, and therefore the jacking rod damages the workpiece can beprevented, and the workpiece can be protected.

Description

technical field [0001] The invention relates to a mold, in particular to a flanging mold with an automatic ejector mechanism. Background technique [0002] At present, most molds have flanging and bending processes in the production process. Whether it is flanging or bending, the product is stuck on the flanging block or bending block. The traditional solution is to add ejector pins on the flanging block to make the product separate from the flanging block. During the production process, the ejector pin has been supporting the product, which has an impact on the positioning of the product on the mold, especially in non-linear turning. side, the stripping force needs to be large, which will cause adverse effects on the surface quality of the product. When there are too many ejector pins, it will affect the strength of the flanging block. Damaged automatic ejector mechanism. Contents of the invention [0003] The object of the present invention is to provide a flanging mo...

Problems solved by technology

The traditional solution is to add ejector pins on the flanging block, so that the product is separated from the flanging block. During the production process, the ejector pin always supports the product, which affects the positioning of the product on the mold, especially in non-linear turning. side, the stripping force needs to be large, which will cause adverse effects on the surface quality of the product. When there are too many ejector pins, it will affect the strength of the flanging block. Damaged automatic ejector mechanism
