Forming device of powder forming machine

Abstract

The invention belongs to the technical field of forming processing equipment, and relates to a forming device of a powder forming machine. The forming device comprises a main shaft, an eccentric wheel, a lower punching mold shaft, a demolding shaft, a demolding plate, jacking mechanisms, a belt wheel and racks; each jacking mechanism comprises a cam, a push rod and an air cylinder; the cams are fixedly arranged on the main shaft in a sleeve mode, one ends of the push rods are connected to plungers of the air cylinders, the other ends of the push rods are located under the cams and are movablyconnected to the cams in a press mode; the eccentric wheel, the cams and the belt wheel are fixedly arranged on the main shaft in a sleeve mode, and the lower punching mold shaft is fixedly installedat a far end of the eccentric wheel; and two jacking mechanisms are symmetrically distributed on the two sides of the eccentric wheel. According to the device, the jacking mechanisms and the cams andthe eccentric wheel are arranged coaxially, so that when a product is pressed, the air cylinders play a pressure maintaining role, the pressing stability is improved, the loss in the pressing processis reduced, the quality and the performance of the powder forming machine are improved, and the cost of the powder forming machine is reduced.

Description

technical field [0001] The invention belongs to the technical field of molding processing equipment, and relates to a molding device of a powder molding machine. Background technique [0002] In recent years, in the field of automatic powder molding machines, both imported products have occupied the high-end market for a long time, and domestic companies continue to produce a large number of low-priced products, which makes the competition of automatic powder molding machines increasingly fierce. Imported powder molding machines are positioned in the market with high quality, high performance and high price, and mainly meet the needs of a small number of customers in the domestic market, while the vast majority of customers in the domestic market still use domestic powder molding machines. At present, the quality and performance of domestic powder molding machines are uneven, and the price is also very different. However, due to the large market capacity, there is still a hu...

Problems solved by technology

Specifically, the lower die mechanism of the existing automatic powder molding machine is only a single cam push rod structure, which makes the working state of the molding unstable and discontinuous; at the same time, during the movement of the cam, the lower die rod pressed by each angle The energy is not fixed, it is easy to cause the loss and instability of the machine in the process of all-mechanical movement, resulting in the stability of the final product cannot be guaranteed
