Multipurpose cold press

Abstract

The invention discloses a multipurpose cold press which comprises a pair of stand columns. An upper top plate and a lower bottom plate are arranged between the stand columns. An electronic control cabinet is arranged on the stand columns. A slide way is arranged in the upper top plate. A pair of hydraulic cylinders are arranged above the upper top plate. The hydraulic cylinders are connected withthe slide way through sliders in the slide way respectively. A piston rod is connected with the lower portion of each hydraulic cylinder. The bottoms of the piston rods are connected with a lower pressing plate through pressing blocks. The lower pressing plate comprises a plurality of lower pressing plate bodies which are in joggle joint. Each lower pressing plate body comprises a bottom layer, amiddle layer and a top layer, wherein a tenon is arranged at one end of the middle layer, a groove is formed in the other end of the middle layer, a slide groove matched with a pressing block is formed in the upper surface of the middle layer, reinforcing ribs are arranged on the two sides of the slide groove, connecting ribs are arranged at the center of the slide groove, the connecting ribs areconnected with the reinforcing ribs on the two sides of the slide groove, and the top layer is laid above the reinforcing ribs on the two sides of the slide groove. The size of the lower pressing plate can be adjusted according to the size of panels, and the distance between the hydraulic cylinders can be adjusted.

Description

technical field [0001] The invention relates to a cold press, in particular to a multipurpose cold press belonging to the field of furniture manufacturing. Background technique [0002] The cold press is an important device used to press furniture panels, wooden doors, plywood and other boards. After the boards are glued, the boards are pre-compressed, also called a pre-press. The existing cold presses can be divided into screw-type cold presses. Presses and hydraulic cold presses. Hydraulic cold presses are more valuable due to their low noise and fast lifting speed. The existing hydraulic cold presses generally use two hydraulic cylinders to push the lower platen to press the plates together. The distance between the two hydraulic cylinders is not adjustable, and the size of the lower pressing plate cannot be adjusted according to the size of the processed plate. Therefore, the existing cold press has the disadvantages that the size of the lower pressing plate cannot be a...

[0002] The cold press is an important device used to press furniture panels, wooden doors, plywood and other boards. After the boards are glued, the boards are pre-compressed, also called a pre-press. The existing cold presses can be divided into screw-type cold presses. Presses and hydraulic cold presses. Hydraulic cold presses are more valuable due to their low noise and fast lifting speed. The existing hydraulic cold presses generally use two hydraulic cylinders to push the lower platen to press the plates together. The distance between the two hydraulic cylinders is not adjustable, and the size of the lower platen cannot be adjusted according to the size of the processed plate

Therefore, the existing cold press has the disadvantages that the size of the lower platen cannot be adjusted according to the size of the plate, and the distance between the hydraulic cylinders cannot be adjusted.
