Hydraulic device for sheets

Abstract

The invention relates to a plate hydraulic device, which includes a hydraulic press and a stamping die installed on the hydraulic press. The hydraulic press includes a frame, a hydraulic main engine installed inside the frame, and a moving module installed on the top of the frame. The moving module passes through The hydraulic cylinder is connected with the hydraulic main engine, and the hydraulic cylinder can move the moving module up and down under the action of the hydraulic main engine; the hydraulic mold includes a connecting plate fixedly connected with the moving module, and the lower side of the connecting plate is provided along its width direction. The pressing plate, the pressing plate includes a fixed part, a connecting part and a pressing part connected in sequence, the cross section of the pressing part is roughly V-shaped, a lower mold is arranged on the base of the frame, and a lower mold is arranged on the lower mold A V-shaped groove matching the pressing part is provided. The invention is simple in structure, easy to use, light in weight, convenient to move, can ensure installation accuracy and stamping precision, and improves the service life of the original stamping device and the quality of stamped angle steel.

Description

technical field [0001] The invention relates to the technical field of hydraulic equipment, in particular to a plate hydraulic device. Background technique [0002] Plate hydraulic device is a kind of mechanical equipment that uses the static pressure of hydraulic oil delivered by oil pump to process metal, plastic, rubber, powder and other products. It is often used in pressing process and pressing forming process, such as forging, stamping, cold extrusion, straightening, Bending, flanging, press-fitting and more. The existing plate hydraulic device generally includes a column, an upper beam, a lower beam, a main oil cylinder and a moving beam. Driven by the main oil cylinder to reciprocate up and down, the moving beam is guided by the column, and its guiding accuracy depends on the column, so it must bear a large working load and play a guiding role at the same time; when working, the upper beam and the lower beam During the stamping process, the frame composed of the co...

Problems solved by technology

The existing plate hydraulic device generally includes a column, an upper beam, a lower beam, a main oil cylinder and a moving beam. Driven by the main oil cylinder to reciprocate up and down, the moving beam is guided by the column, and its guiding accuracy depends on the column, so it must bear a large working load and play a guiding role at the same time; when working, the upper beam and the lower beam During the stamping process, the frame composed of the column and the column is subjected to a pair of internal forces of equal size and opposite direction, resulting in bending deformation, which will cause the bending of the column, and the elongation deformation of the column will not be absolutely consistent , thus seriously affecting the guiding accuracy of the moving beam
