A powder pressure molding device

Abstract

The invention provides a powder pressure forming device comprising a machine body, a feeding port, guiding plates, a control switch, an upper connecting layer, a guide rail, a protrusion, a slider, achute, a feeding barrel, a moving spring, an ejecting block, a dredging hydraulic cylinder, a dredging rod, a limit layer, a solenoid valve, a push switch, a rotary motor, a hydraulic cylinder, an elastic baffle, a return spring, a piston rod, a pressure roller, a connecting layer, a high pressure spring, a pressure block and a forming template. The top of the machine body is fixedly provided withthe feeding port, the left and right ends of the bottom of the feeding port are fixedly provided with the guiding plates, the control switch is fixedly mounted on the right side of the machine body,the left and right ends of the machine body are in seamless joint with the upper connecting layer, and the inner side of the upper connecting layer is fixedly provided with the guide rail. When a feeding structure is blocked, a blockage position can be automatically dredged, the pressed shape density distribution is more uniform in the pressing process, and the flexibility molding effect and practicability of the forming device are enhanced.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a powder pressure molding device. Background technique [0002] The powder forming machine can produce high-precision, multi-step pressed products at one time, and has the characteristics of wide application range, high production efficiency and high material utilization. It has been widely used in the pressing of various metals, ceramics, bakelite and other powder products. , and the shape of the pressed product is becoming more and more complicated. The powder forming method using external pressure in the die is also called powder compression forming. The powder compression forming process consists of three steps: powder loading, pressing and demoulding, but the existing During the pressing and forming process of many powder forming machines, if the powder particles are relatively large or contain some water, it is easy to cause the feeding structure of the device to be bloc...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a powder pressure molding device to solve the problem that when the feeding structure of the molding device is blocked, the blockage cannot be cleaned quickly, which affects the work efficiency and easily leads to uneven density distribution of the green compact during the pressing process. question
