Abstract

A hydraulic forming device, including a supercharged device for supplying liquids to the processing parts. The booster device includes a booster mechanism used to pressure the low -pressure liquid to high pressure liquid, and the driver mechanism for providing power to the supercharged mechanism; The supercharged mechanism includes the first piston that can be inserted inside the first cylinder tube, the first piston is closed in the inner wall of the first cylinder, and the first piston and the first cylinder cylinderThere is a storage cavity between the inner walls. There is an exit connected to the liquid storage cavity on the first cylinder.; Drivers include motors, screws, nuts that meshing with screws, any of the two components of screw and nuts connected to the motor, and the other movement direction is connected to the first piston transmission.It is a self -locking system and facilitated controlling device, which is a good guarantee to ensure the quality of the workpiece during the hydraulic processing process.

Description

technical field [0001] The present invention designs a hydroforming equipment. Background technique [0002] The pressure boosting device in the existing hydroforming equipment uses a motor to drive the high and low pressure pumps to increase the pressure of the low pressure fluid, and the output high pressure fluid is pumped into the pipe fittings for pipe expansion. This supercharging device consumes a lot of power, and because the high and low pressure pumps are not very sensitive to the control of speed and start and stop, it affects the processing quality of the pipe fittings. Contents of the invention [0003] The object of the present invention is to provide a hydroforming equipment with a self-locking system and an easy-to-control booster device, which can well ensure the quality of workpieces during hydraulic processing. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A hydroforming equipment, whi...
