Constant-pressure blank pressing mechanism

Abstract

The present patent relates to the field of press molding, and discloses a constant-pressure blank pressing mechanism, which comprises a push rod and a sleeve that are coaxial to each other. The push rod is fixed to the sleeve. A power rod is connected in the sleeve in a sliding manner. A power part is disposed at one end, far away from the sleeve, of the power rod. A ratchet is disposed on the power rod. A through hole is formed in the sleeve in a direction perpendicular to an axis of the sleeve. A support in a cylindrical form is fixed in the through hole. A wedge block is connected in the support in a sliding manner, and comprises a wedge surface against the ratchet. A threaded hole in which a matching screw is connected by means of threads is formed in the wedge block. A baffle is further fixed in the support. The screw penetrates through the baffle. A spring is compressed between the baffle and the wedge block. The present patent is intended to provide a constant-pressure blank pressing mechanism allowing setting of the maximum pressure of pressing ceramic product blanks, thus preventing excessive pressing pressure.

Description

technical field [0001] The invention relates to the field of compression molding, in particular to a constant pressure blank pressing mechanism. Background technique [0002] In the production and processing of ceramic products, the traditional production process is that the operator shapes the required shape with both hands on the drawing machine, but the production efficiency of the traditional process is low. Extrusion molding is carried out to form a blank, and then the blank is finished for shaping. [0003] Ceramic products usually have the characteristics of thin wall and hollow interior. During the extrusion process of the blank, there are certain requirements for the extrusion pressure. The pressure should not be too large, and excessive pressure will cause excessive extrusion of the clay. On the one hand, the wall thickness of the ceramic product is not easy to control, or the hollow part of the blank is deformed; on the other hand, excessive pressure will cause t...

[0002] In the production and processing of ceramic products, the traditional production process is that the operator shapes the required shape with both hands on the drawing machine, but the production efficiency of the traditional process is low. Carry out extrusion molding to form a blank, and then finish machining the blank for shaping

[0003] Ceramic products usually have the characteristics of thin wall and hollow interior. During the extrusion process of the blank, there are certain requirements for the extrusion pressure. The pressure should not be too large, and excessive pressure will cause excessive extrusion of the clay. On the one hand, the wall thickness of the ceramic product is not easy to control, or the hollow part of the blank is deformed; on the other hand, excessive pressure will cause the clay to be too compact, and it is easy to crack during the firing process of the ceramic product
