每组油缸的活塞杆上端与一分油路相对放置。每组活塞杆的下端连接一压料块。

The upper end of each rod with a cylinder placed opposite sub-passage. A piston rod connected to the lower end of each block nip. A tension spring connected to the nip between the cylinder block and the cylinder. High-pressure oil into the oil block, then the block assigned by the oil to the respective cylinder. High pressure oil push rod down, thus promoting the nip block pressed sheet. The return trip, the first high-pressure oil unloading, the rebound launch nip tension spring block reset.

The upper end of the piston rod for each group of cylinders is placed opposite to a branch of the oil circuit. The lower end of each set of piston rods is connected to a pressure block. The pressure block is connected between the pressure block and the cylinder block of the cylinder. The high-pressure oil enters the sub-block, which is then assigned to the cylinders. The high-pressure oil pushes the piston rod down, which pushes the pressure block to hold the plate. On the return trip, the high-pressure oil is unloaded first, and the reed rebound initiates the pressure block reset.

The upper end of the piston rod of each group of oil cylinders is placed opposite to a oil distribution channel. The lower end of each piston rod is connected with a pressing block. The material pressing block and the cylinder block of the oil cylinder are connected with a tension spring. The high-pressure oil enters into the oil separation block, which is then distributed to each cylinder. The high-pressure oil pushes the piston rod down, thus pushing the pressing block to press the plate. During the return trip, the high-pressure oil is unloaded first, and the spring rebound starts to reset the pressing block.
