The present invention discloses a special hydraulic press for bulging pressing forming of an automobile axle housing and a pressing forming method. A hydraulic press body is a closed frame consisting of an upper cross beam, a lower cross beam, four stand columns I, II, III, and IV, four vertical pull rods I, II, III, and IV, and four transverse pull rods I, II, III, and IV, and is used for balancing a deformation force up to 3000 T in the vertical direction or the horizontal direction in the pressing forming process. During pressing forming, the downward speeds of a main hydraulic cylinder, small left and right vertical hydraulic cylinders are precisely controlled to prevent the left end, the right end and the middle of the tube blank from bending.

Systems, devices, and methods are disclosed for a rosin press that allows improved extraction over existing presses. The press includes improved platens for rosin collection with built-in gutter rail collection systems and well-distributed force on the pressed product and multiple hydraulic rams. In addition, computerized systems are provided for controlling and monitoring the system in an automated fashion, as well as safety features to prevent injury and damage to the product, especially during automated pressing.

A hydraulic forging press machine and a control method, whereby surging of the forging load or dead zones where the forging speed goes to zero is suppressed, and forging is performed with high precision throughout a wider range than the prior art, from low to high load. Pressure cylinders have a main pressure cylinder configured so working fluid is supplied during forging, and secondary pressure cylinders are configured so supplying and stopping of the supply of working fluid thereto are switched in response to the forging load, head-side hydraulic chambers of the secondary pressure cylinders being connected to a head-side hydraulic chamber of the main pressure cylinder via electromagnetic switching valves. Only the main pressure cylinder is used until the forging load exceeds a set load, and the number of secondary pressure cylinders used is sequentially increased as the forging load increases after the forging load exceeds the set load.

A linear actuator is disclosed. The linear actuator comprises a cylinder portion and a base portion. The cylinder portion comprises a housing defining internally a compression chamber for containing a fluid and comprising a piston assembly that can reciprocate within the compression chamber. The housing further defines a cylinder port in fluid communication with said compression chamber. The base portion defines a first base port and a second base port and a passage extending therebetween fluidly communicating the first base port with the second base port, and comprises valve means operable to control the flow of fluid through the second base port, in which the valve means is actuatable between an open condition in which the flow of fluid through the second base port is permitted, and a closed condition in which the flow of fluid through the second base port is substantially prevented. The cylinder portion is releasably engageable with the base portion such that the cylinder portion and the base portion may be arranged in an engaged condition in which engaged condition the cylinder port and the second base port are in fluid communication.
