Automatic cold press

Abstract

The invention relates to an automatic cold press. The automatic cold press comprises a frame, an upper pressure head base, an upper pressure head, a lower pressure head base, a lower pressure head, a worktable, a mold cavity arranged on the worktable and matched with the upper pressure head and the lower pressure head, a feeding device, a supply device for driving the feeding device to move to the mold cavity, and a driving mechanism for driving the upper pressure head and the lower pressure head to move up and down; a position of a discharge port of the feeding device corresponding to the mold cavity is a first station; a position of the discharge port of the feeding device leaving from the mold cavity is a second station; and the supply device has a first driving part for driving the feeding device to perform a reciprocating motion between the first station and the second station, and a second driving part for driving the feeding device to perform a reciprocating motion nearby the first station. After the technical scheme is adopted, the second driving part drives the feeding device to perform the reciprocating motion nearby the first station, so that the shaking effect of the feeding device is realized, the uniform falling of powder into the mold cavity is realized, and the cold pressing quality of products is promoted.

Description

technical field [0001] The invention relates to an automatic cold press. Background technique [0002] Known automatic cold presses for pressing metallurgical powders generally include a frame, an upper support that can be moved up and down above the frame, an upper pressure head seat that is disposed on the lower part of the upper support, and an upper pressure head that is disposed on the upper support. The upper pressure head at the lower end of the seat, the guide body which is arranged on the frame and forms the guide hole matching the upper pressure head seat, the lower support body which can be moved up and down under the frame, and the lower support body which is arranged on the lower support body The lower pressing head seat, the lower pressing head set on the lower pressing head seat opposite to the upper pressing head, the workbench which can be moved up and down between the upper and lower pressing heads, and the reset elasticity arranged between the workbench an...

Problems solved by technology

In this kind of cold press, the material distribution device (or feeding device) is generally driven by the cylinder or oil cylinder to move to the die hole to transport the material powder. During use, it is found that due to the certain humidity and viscosity between the material powder, After being fed into the die hole from the material distributing device, it is difficult to fill the die hole evenly with the powder. After the powder is cold-pressed, there will be problems that the block is difficult to form a predetermined shape and the block is not uniform. The block needs to be processed again later. processing, affecting productivity and product quality
