Multifunctional hydraulic combined device

Abstract

The invention relates to a multi-functional hydraulic merging device, which comprises a movable module for clamping and a movable module for stretching. The cylinder for clamping comprises a main part, a movable piston is arranged in the main part, and a direction control device is provided at the front port of the main part. A No. 1 piston rod and a No. 2 piston rod are connected to the movable piston. The No. 1 piston rod protrudes from the direction control device, and the No. 2 piston rod protrudes from the bottom wall of the main part. The end of the No. 1 piston rod is fixedly connected with a locking pin, and the outer circumference of the locking pin fits with the inner wall of the guide cylinder in clearance; The shape and size of the inner hole and the locking pin are adapted, and the housing, the locking pin, the guide cylinder and the main body share an axis. A strip sensing device is installed on the No. 1 piston rod, and two touchable switches matched with the strip sensing device are installed on the support of the direction control device. The device can combine the drawing movable module and the blank holder movable module, and the total tonnage is the sum of the blank holder tonnage and the drawing tonnage.

Description

technical field [0001] The invention relates to a hydraulic machine, in particular to a multifunctional hydraulic combining device. Background technique [0002] In the prior art, double-acting hydraulic presses are divided into four-column type and frame type. With the development of the automobile manufacturing industry, large-scale frame type hydraulic presses are widely used in domestic and foreign markets. The double-acting hydraulic press includes a movable module for the blank holder driven by a blank holder and a movable stretch module for the stretch drive. The blank holder cylinder includes a main part in which a movable piston is arranged, and the front port of the main part is provided with a In the direction control device, a No. 1 piston rod and a No. 2 piston rod are connected to the movable piston. The No. 1 piston rod protrudes from the direction control device, and the No. 2 piston rod protrudes from the bottom wall of the main body. [0003] The stretchin...

Problems solved by technology

[0003] The stretching movable module and the blanking movable module work separately when forming the workpiece, mainly to realize the stretching process, and each has a division of labor. The blanking and bending processes can only be completed independently by the stretching cylinder or the blanking cylinder , the total tonnage of the machine tool cannot be fully used, and the value of the equipment is not reflected
