Multipurpose cold press convenient to load and unload

Abstract

The invention discloses a multipurpose cold press convenient to load and unload. The multipurpose cold press comprises a pair of stand columns; an upper top plate and a lower baseplate are arranged between the stand columns; a first slide way is formed in the upper top plate; a pair of hydraulic cylinders is arranged above the upper top plate; a piston rod is connected below the hydraulic cylinders; the bottom of the piston rod is connected with a lower pressing plate by a pressing block; a cuboid indent is formed in the surface of the lower baseplate; a material placing platform is arranged on one side of the lower baseplate; a second slide way is formed in the material placing platform; the second slide way extends to the cuboid indent in the surface of the lower baseplate, and is provided with a slide platform; the lower pressing plate comprises multiple tenoned lower pressing plate monomers; the lower pressing plate monomers comprise bottom layers, middle layers and top layers; convex tenons are arranged at one ends of the middle layers, and grooves are formed in the other ends; and chutes matched with pressing blocks are formed in the upper surfaces of the middle layers. The multipurpose cold press has the advantages of capability of adjusting the size of the lower pressing plate according to sizes of boards, capability of adjusting the distance between the hydraulic cylinders and convenience to load and unload the boards.

Description

technical field [0001] The invention relates to a cold press, in particular to a multipurpose cold press with convenient loading and unloading, which belongs 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 cannot be adjusted, and the size of the lower platen cannot be adjusted according to the size of the processed plate. The current cold press has rack columns on both sides, and a lower platen a...

Problems solved by technology

[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 cannot be adjusted, and the size of the lower platen cannot be adjusted according to the size of the processed plate. The current cold press has rack columns on both sides, and a lower platen above the lower plate. When the plate is large, the upper plate It will be very difficult to lower the plate, especially when the number of pre-pressed plates is large, when the uppermost plate is loaded, the remaining space inside the cold press will become smaller and smaller. When the plate is unloaded, due to the small internal space of the cold press, It is easy to collide with the lower platen during blanking, and there is no separate loading and unloading device to enable the plate to be loaded and unloaded outside the cold press

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, the distance between the hydraulic cylinders cannot be adjusted, and the loading and unloading of the plate is inconvenient.
