Solid particle male die forming mold with movable brake beads and radial thrust

Abstract

The invention relates to a solid particle male die forming mold with movable brake beads and radial thrust, which comprises a female die, forming solid particles, brake beads, binder rings, hold-down air cylinders, a liner plate, a lower die block, a top rod, a pressure block, top feeding air cylinders, top plates, radial solid particles, sealing plates, a stock, and the like. The top feeding air cylinders are mounted on the lower die block, the working ends of the top feeding air cylinders penetrate through pressing plates to contact the top plates arranged in the binder rings and push against the lower surfaces of the top plates, the sealing plates are mounted on the binder rings, the sealing plates, the female die, the binder rings, the top plates and the stock form a radial closed space in the forming process, and the radial solid particles are arranged in the radial closed space. The novel mold combines the movable brake beads, the solid particle male die and the radial trust enhanced by solid particle media and has conveniently controlled brake bead resistance, safe and reliable radial trust loading and solid particle male die forming, no pollution, easier forming in practical production and remarkably improved product forming quality.

Description

technical field [0001] The invention belongs to stamping die technology, and in particular relates to a solid particle punch forming die with movable drawbeads and radial thrust, which is mainly aimed at the mold with variable drawbead height, radial thrust and variable punch shape. technical background [0002] Ordinary forming dies have no radial thrust, and the forming is completed by the punch driving the sheet and pulling it toward the die. For drawing dies with radial hydraulic pressure, the radial thrust is realized by liquid pressure, and the sealing problem is difficult to solve; at the same time, the drawing dies with hydraulic devices have a more complicated structure and higher cost. [0003] Ordinary molds are made of steel molds, and the shape of the punch does not change during the drawing process. This kind of mold is prone to uneven stress and cracking during the deep drawing process, and the mold is prone to wear and tear, which reduces the service life of...

Problems solved by technology

[0005] The present invention aims at the problems that the existing mold cannot change the resistance of the variable drawbead, the ordinary forming mold has no radial thrust, the shape of the punch is not changeable, and the sealing problem of the hydraulic drawing mold is difficult to solve. The mold with the amount of solid particles can achieve variable drawbead resistance, variable punch shape, provide radial thrust, and solve sealing problems
