Problems solved by technology

[0005] However, since the powder material in the feeding barrel will be continuously discharged from the outlet on it, when there is too much powder material in the feeding barrel, it will affect the normal feeding
That is to say, too much powder material will enter the mold, so that the yield of the pressed product is not high
[0006] At the same time, when there is too much powder material in the feeding cylinder, it may also cause blockage, and eventually there is not enough powder material to enter the mold, which affects the normal operation of the powder compression molding machine

Embodiment Construction

[0031] As shown in Figure 1, the constant feeding device of the powder compression molding machine is set at the mold 7 of the powder compression molding machine. It consists of a hopper 1, an upper feeding barrel 2, a lower feeding barrel 3 and a feeding mechanism.

[0032] The hopper 1 is in communication with the upper feeding barrel 2, and the upper feeding barrel 2 is located at the upper part of the lower feeding barrel 3. The feeding mechanism is located between the upper feeding barrel 2 and the lower feeding barrel 3, and it connects the upper feeding barrel 2 and the lower feeding barrel 3 with each other. Among them, the lower feeding barrel 3 is located on the upper part of the mold 7 of the powder molding machine.

[0033] In order to allow the powder materials to pass smoothly, a feeding paddle 4 is provided in both the upper feeding barrel 2 and the lower feeding barrel 3. The feeding paddle 4 is composed of a drive shaft 41 and a number of feeding bars 42. The inne...

Abstract

The present invention provides constant-quantity material feeder of powder molding machine and belongs to the field of mechanical technology. The constant-quantity material feeder includes one material bin, one feeding tube connected to the material bin including one upper part and one lower part with rotating material feeding paddle each, and one material feeding mechanism set between the upper part and the lower part for feeding material from the upper part to the lower part in required quantity and speed. The constant-quantity material feeder has compact structure, high stability and capacity of raising the product quality of the powder molding machine.

Description

Technical field [0001] The invention belongs to the technical field of machinery, and relates to a powder compression molding machine, in particular a constant feeding device of the powder compression molding machine. Background technique [0002] The workpiece made of powder material die-casting has simple manufacturing process and low manufacturing cost. Therefore, powder compression molding machines are widely used in mechanical processing. [0003] In order to conveniently feed the powder molding machine, a feeding device is provided on the powder molding machine. The existing feeding device includes a hopper and a feeding barrel connected with the hopper, and the discharge port of the feeding barrel is located at the mold of the powder molding machine. Usually, a paddle for agitating the powder material is also provided in the feeding barrel. [0004] After the powder material enters the feeding barrel from the hopper, at this time the paddle makes the powder material pass s...
