Self-locating and rapid cooling structure for cold pressing machine

Abstract

The invention discloses a self-locating and rapid cooling structure for a cold pressing machine. The self-locating and rapid cooling structure comprises an outer frame and multiple oil cylinders. A hydraulic lifting rod is connected into each oil cylinder. The multiple hydraulic lifting rods are connected with a pressing plate together. A fixing platform is arranged on the portion, directly facingthe pressing plate, of the outer frame. A fixing structure is connected into the fixing platform. The fixing structure comprises a ring-shaped channel formed in the fixing platform. The other side ofthe ring-shaped channel is provided with a negative pressure cavity formed in the inner wall of the outer frame in a penetrating manner. A sealing plate is connected into the negative pressure cavityin a sealing and sliding manner. The structure has the advantages that by means of the vacuum effect of the negative pressure groove, a plate body, located on a bottom layer, of the fixing platform can be located and strengthened, when the pressing plate moves down, vibrating occurs, but the displacement phenomenon is avoided, the situation that the position of the plate body is adjusted for a second time is avoided, under the magnetothermal effect, rapid cooling and heat absorbing are carried out on a plate to be machined, and local overheating is avoided.

Description

technical field [0001] The invention relates to the technical field of cold presses, in particular to a self-positioning rapid cooling structure for cold presses. Background technique [0002] The cold press is a pressure device used for panel furniture bonding and wood-based panel veneer pressing at room temperature. Its working principle is that, under the action of its own hydraulic system, the hydraulic cylinder drives the pressure plate down to realize The plank blank fixed on the fixed table is press-processed. [0003] However, in the prior art, when the cold press is processing the plank, it often needs to carry out pressure work on the two-layer plank, wherein the plank at the bottom will be directly placed on the working platform, and the plane of the working platform is relatively smooth, so that in the long-term After use, when the pressure plate is lowered, the working platform will vibrate to a certain extent. At this time, the smooth and flat working platform...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the cold press in the prior art is prone to uneven edges when processing multi-layer boards, which affects the processing effect, and proposes a cold press with self-positioning quick cooling structure
