Abstract

The invention discloses a device for forging a hydraulic cylinder body. The device comprises a machine frame, a concave die, a hole forging unit and a power unit; the concave die is fixed on the lowerpart of the machine frame, and a groove used for forging the cylinder body is formed in the concave die; the hole forging unit comprises a forging head, an air bag sleeve, forging rods, guide rods and a fixing plate; the forging rods are fixed on the fixing plate, a hydraulic cavity is formed in the forging rods, and the upper part of the forging head is connected with the hydraulic cavity in a sliding mode; the air bag sleeve is arranged outside the upper part of the forging head in a sleeved mode, and a plurality of one-way air inlet valves are arranged on the air bag sleeve; a plurality ofair outlet channels are formed in the forging rods, and one-way air outlet valves are arranged in the air outlet channels; the power unit comprises a supporting shaft, a pressing rod, a hydraulic pump, a piston cylinder and a connecting pipe; the middle part of the pressing rod is rotationally connected with the supporting shaft, one end of the pressing rod is positioned above the forging rod, and the other end of the pressing rod is located above the piston cylinder; and the hydraulic pump communicates with the hydraulic cavity and the piston cylinder through the connecting pipe. Compared with the prior art, the device has the advantages that operation is simple, the machining allowance is small when the cylinder body is forged, and mechanical property of the forged cylinder body is good.

Description

technical field [0001] The invention belongs to the technical field of forging, and specifically discloses a device for forging a cylinder body of a hydraulic cylinder. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. The hydraulic cylinder is basically composed of cylinder barrel and cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Among them, the cylinder body is the most important, and the quality of the cylinder body directly affects the use and life of the hydraulic cylinder. [0003] At present, the cylinder body of the hydraulic cylinder is mainly manufactured by forging process. ...
