Certainly, for the better intercommunication that realizes between oil drum 200 and the cylinder body 100, consequently, the preferred hose of conveyer pipe 400 in this embodiment, the hose can conveniently be buckled, makes better the intercommunication that carries on between oil drum 200 and the cylinder body 100 to can adapt to more abominable occasion.

Referring to fig. 1 and 2, in order to realize pressurization, in the present embodiment, a first driving member 110 is disposed at a top end of a cylinder 100, a cylinder 120, a first lead screw 130 and a piston cylinder 140 are disposed inside the cylinder 100, the first lead screw 130 is disposed in the cylinder 120 and connected to the first driving member 110, the piston cylinder 140 is disposed between the cylinder 100 and the cylinder 120 and provided with a push rod 150, one end of the push rod 150 is connected to the first lead screw 130, and the other end is connected to a bottom of the piston cylinder 140.

Meanwhile, the supercharger 300 includes a supercharging cylinder 310, a second driver 320, a second lead screw 330 and a piston rod 340, the second driver 320 is disposed at the top end of the supercharging cylinder 310, the second lead screw 330 and the piston rod 340 are located inside the supercharging cylinder 310, one end of the second lead screw 330 is connected with the second driver 320, the other end is connected with one end of the piston rod 340, and the other end of the piston rod 340 is located in the oil passage 500.

When the servo booster cylinder of this embodiment works, the first driving member 110 is started to drive the first lead screw 130 to rotate, when the first lead screw 130 rotates, the push rod 150 is driven to move downwards, and simultaneously the piston cylinder 140 moves downwards synchronously and acts on various devices, such as a stamping die, etc., when the piston cylinder 140 moves downwards, a space is formed in the cylinder body 100, at this time, the oil in the oil drum 200 flows into the cylinder body 100 along the oil passage 500 formed by the delivery pipe 400, and when the piston cylinder 140 moves downwards to a set position, the second driving member 320 is started to drive the second lead screw 330 to rotate, when the second lead screw 330 rotates, the piston rod 340 moves downwards, and in the process of moving the piston rod 340 downwards, the oil inlet of the oil passage 500 is blocked, the end portion extrudes the oil in the oil passage 500, so that the piston cylinder 140 in the cylinder body 100 continues to press downwards, therefore, the purpose of pressurization is achieved, and of course, when the second driver 320 drives the piston rod 340 to extrude the oil in the oil passage 500, the first driver 110 keeps synchronous operation and drives the piston cylinder 140 to press down, so that the servo pressurization cylinder operates reasonably.

After the pressurization is finished, the second driving member 320 drives the second screw 330 to rotate reversely, the second screw 330 drives the piston rod 340 to reset, and opens the inflow port of the oil passage 500, then the first driving member 110 drives the first screw 130 to rotate reversely, the first screw 130 drives the push rod 150 and the piston cylinder 140 to reset, and when the piston cylinder 140 resets upwards, the oil in the cylinder body 100 is squeezed back into the oil drum 200 from the oil passage 500, so that the circulation is realized, and finally, the design of the servo pressurization cylinder is reasonable.

The first lead screw 130 is disposed in the cylinder 120, so that oil entering the cylinder 100 can be prevented from flowing into the connection between the first lead screw 130 and the push rod 150, thereby preventing the oil from blocking when the push rod 150 is reset, and facilitating the reset of the piston cylinder 140 driven by the push rod 150.

In addition, in order to make the structural design of the servo pressurizing cylinder reasonable, the piston part on the piston cylinder 140 has a diameter matching the distance from the inner wall of the cylinder body 100 to the outer wall of the cylinder barrel 120, and at the same time, the piston part on the piston rod 340 has a diameter matching the inner diameter of the pressurizing cylinder barrel 310, so that the piston motion can be performed; in order to extrude the oil in the oil passage 500, the piston rod 340 is located at one end of the oil passage 500, and the outer diameter of the piston rod needs to be matched with the inner diameter of the oil passage 500 so as to extrude the oil in the oil passage 500.
