Technical Field

The invention belongs to the technical field of superhard material synthesis, and particularly relates to a safety device of a cubic press and a safety block mounting method.

Background

In the production process of superhard materials such as artificial diamond and the like, hinge type cubic presses are mainly adopted domestically, and the collision accident of six pressing hammers of the presses is often caused by the error of operators.

The main violation factors are the following:

in the first case: when the six working cylinders drive the top hammers to rapidly return to the original opening positions, the synthesized assembly blocks are not taken out in time, the working buttons are continuously started to carry out secondary synthesis, the synthesized sealing edges of the regular hexahedron assembly blocks are very thin after high-pressure pressing, and if the six top hammers carry out secondary extrusion, a six-hammer collision accident can occur, so that serious economic loss is caused.

In the second case: when the six top hammers all return to the original positions, the synthesized assembly blocks are taken out, but new assembly blocks are not put into the synthesis cavity, and the working button is started to carry out high-pressure pressurization on the vacant synthesis cavity, so that the six alloy top hammers are forced to seriously collide with each other.

In the third case: the new assembly block and the assembly block which is already synthesized are misplaced, and the synthesized block is taken out and then put into the synthesis cavity again to continue working, and the result is the same as the first case.

Therefore, a set of protection device and a control method need to be researched to effectively monitor the block mounting action of the cubic press, so that the problems are solved.
