Description

Technical Field

[0001] The utility model relates to the technical field of oil presses, in particular to a cold extrusion forming oil press. Background Art

[0002] A hydraulic press uses specialized hydraulic oil as its working medium and a hydraulic pump as its power source. The pump's force forces the hydraulic oil through hydraulic lines and into the cylinder. The cylinder then contains several sets of seals that work together, each with its own seal. Seals in different locations are different, but all seal to prevent the hydraulic oil from leaking. Finally, a one-way valve circulates the hydraulic oil through the tank, causing the cylinder to circulate and perform work, thus completing a specific mechanical action and serving as a productive force.

[0003] When the existing device is hydraulic, it is not convenient to fix and clamp the hydraulic objects, resulting in excessive pressure during hydraulic operation. The deformation of the device can easily cause hydraulic deviation, reduce the accuracy of hydraulic installation, and greatly reduce the practicality of the device. When the hydraulic plate is raised or lowered, the staff often apply pressure to the base directly with the pressure plate. If this is done for a long time, it is easy to cause cracks in the base of the device, reducing the service life of the device and reducing the safety of the device.

[0004] For example, a cold extrusion forming hydraulic press disclosed in Chinese patent CN217047569U is provided, wherein a hydraulic box is installed on the top of the device top plate, a rotating wheel and a buffer pad, a motor is installed on the surface of the hydraulic box on the top of the device top plate, a contraction plate is installed inside the device top plate, a sliding rod is installed on the inside of the contraction plate, a lifting plate is installed on the periphery of the sliding rod, a device base is installed on the bottom of the sliding rod, and a screw is installed on the internal rotating shaft of the device base. The hydraulic box is installed on the top of the device top plate. When the device is in use, the staff can rotate the screw by turning the rotating wheel, which can drive the two sets of threaded blocks to move toward each other. At this time, the fixing plates installed on the top of the two sets of connecting plates can be driven to clamp the hydraulic object, fix the hydraulic object, prevent the hydraulic pressure of the device from deviating, and improve the accuracy of the hydraulic pressure.

[0005] However, the hydraulic press in the prior art lacks a structure for ejecting the workpiece after hydraulic forming, which causes the workpiece to be easily stuck inside the mold and difficult to remove, affecting the efficiency of the hydraulic forming work.

[0006] For this reason we urgently need to provide a kind of cold extrusion forming hydraulic press. Utility Model Content
