Description

Technical Field

[0001] The present application relates to the technical field of four-column hydraulic presses, and in particular to a clamping device for a four-column hydraulic press. Background Art

[0002] The four-column hydraulic press is a mechanical equipment that uses the static pressure of hydraulic oil delivered by an oil pump to process metal, plastic, rubber, wood, powder and other products. The four-column hydraulic press, also known as an oil press, is a machine that uses liquid pressure transmission based on Pascal's law. When the four-column hydraulic press is in use, a clamping device is required to clamp and fix the workpiece.

[0003] At present, most of the related four-column hydraulic press clamping devices are simple clamping plate structures, lacking an assembled limiting structure. The device cannot be freely assembled according to the height of the workpiece to be clamped and processed so that the device can reach the clamping height of the workpiece, thus limiting the scope of use of the device.

The workpiece is clamped and fixed by the connection plate, the positioning plate and the limit plate. By connecting the external coolant introduction structure with the cooling pipe and introducing the coolant, the cooling pipe and the limit plate are made of heat-conducting copper, which can quickly absorb the heat of the workpiece and take it away by the coolant.

[0008] Preferably, the connection plates and the positioning plates on both sides of the limiting groove are provided with insertion holes inside, and the bottom of the positioning plate is fixedly connected with an insertion rod, and the insertion rod is engaged with the insertion hole.

[0009] The friction between the connecting plate and the positioning plate is increased by inserting the insert rod into the inside of the insert hole, thereby increasing the stabilizing effect of the connection between the connecting plate and the positioning plate.

[0010] Preferably, a positioning piece is fixedly connected between the fixing plate and the four-column hydraulic press body, and a bolt is movably installed between the positioning piece and the four-column hydraulic press body.

[0011] The contact area between the fixed plate and the four-column hydraulic press body is increased by the positioning piece, and the positioning piece and the four-column hydraulic press body are fixed by bolts, thereby increasing the stability effect of the fixed plate installation.

[0012] Preferably, a flange is fixedly connected to one side of the cooling pipe, and screw holes are provided inside the flange.
