Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic presses, in particular to a positioning fixture for a hydraulic single-function press. Background Art

[0002] A hydraulic press is a machine that uses special hydraulic oil as the working medium and a hydraulic pump as the power source. The hydraulic oil enters the cylinder / piston through the hydraulic pipeline by the force of the pump. Then there are several sets of seals that cooperate with each other in the cylinder / piston. The seals in different positions are different, but they all play a sealing role to prevent the hydraulic oil from leaking. Finally, the hydraulic oil circulates in the oil tank through a one-way valve to make the cylinder / piston circulate and do work, thereby completing a certain mechanical action as a kind of productivity.

[0003] In the process of punching forgings by existing hydraulic presses, due to the high temperature of the forgings, the position of the forgings needs to be adjusted by power equipment or manually after being placed on the workbench. The center position of the workpiece is then found by adjusting the position of the punch and then punching is performed. This operation method has complicated procedures.

The punching positioning device for a hydraulic press has a reasonable design, and can place the workpiece on the surface of the adjustment platform, adjust the limit of the lateral direction of the workpiece by the movable block, and then move the adjustment platform longitudinally to quickly find the center position concentric with the punch, which is easy to operate, safe and reliable, improves the work efficiency of centering and positioning, and is beneficial to improving the molding quality of the product.
