[0002] Before the anode plate enters the electrolytic cell, in order to improve the electrolysis efficiency and the quality of the cathode plate, the anode plate needs to be flattened, and the press is one of the key equipment. Existing hydraulic presses at home and abroad mostly use assembled frames and built-in pipelines, or leave a large idle stroke for maintenance. This method is extremely difficult to judge if oil leakage or internal oil seepage occurs, and maintenance and treatment are also extremely time-consuming and labor-intensive; there are also external oil cylinders, but the inlet / return oil pipes are connected to the front and rear covers of the oil cylinder, and the oil cylinders on the press are installed more densely, which makes it difficult to repair the inlet / return oil pipes on the side of the press frame. When a cylinder leaks or has internal oil seepage, it is necessary to remove all the surrounding cylinders to handle the faulty cylinder, which is extremely time-consuming and labor-intensive.

[0030] See also Figure 1 to Figure 2 The embodiment of the present application provides a special oil cylinder, including a rear end cover 1, a second piston 2, a first piston 3, a guide pipe 4, a cylinder barrel 5, a piston rod 6, a front end cover 7, and a guide sleeve 8. The guide sleeve 8 is connected to the front end cover 7, and the guide sleeve 8 is provided with a sliding hole; one end of the cylinder barrel 5 is sealed with the guide sleeve 8; the rear end cover 1 is sealed with the other end of the cylinder barrel 5, and the rear end cover 1 is provided with a first oil inlet / outlet hole 11 and a second oil inlet / outlet hole 12; the piston rod 6 is slidably matched in the sliding hole of the guide sleeve 8, and the end of the piston rod 6 close to the rear end cover 1 is provided with a groove, and a connecting hole connecting the groove to the side of the piston rod 6; the first piston 3 is installed on the piston rod 6, and the first piston 3 is slidably matched with the inner wall of the cylinder barrel 5; the guide pipe 4 is arranged in the second oil inlet / outlet hole 12, and the end of the guide pipe 4 extends into the groove of the piston rod 6; the second piston 2 sleeves are slidably matched on the guide pipe 4, and the second piston 2 is connected to the first piston 3.

[0031] When the piston rod 6 needs to be extended, the oil pipe connected to the first oil inlet / outlet hole 11 delivers hydraulic oil to the oil cylinder, and the pressure of the hydraulic oil acts on the first piston 3 and the second piston 2, so that the piston rod 6 extends. Conversely, when the piston rod 6 needs to be retracted, the oil pipe connected to the second oil inlet / outlet hole 12 delivers hydraulic oil to the oil cylinder, and the hydraulic oil enters the groove of the piston rod 6 through the guide pipe 4, and then flows from the connecting hole of the piston rod 6 to the closed space surrounded by the first piston 3, the piston rod 6 and the guide sleeve 8. The hydraulic oil entering the space gives the first piston 3 a reverse hydraulic pressure ( Figure 1 The force is directed to the left in the middle), thereby causing the first piston 3 and the piston rod 6 to slide to the left, and the piston rod 6 to retract.

[0032] Therefore, the dedicated oil cylinder provided in this embodiment, under the premise of ensuring that the oil cylinder can work normally, the first oil inlet / outlet hole 11 and the second oil inlet / outlet hole 12 of the dedicated oil cylinder are both arranged on the rear end cover 1, so that the hydraulic oil pipes connected to the oil cylinder are all connected to the rear end cover 1, so as to facilitate the maintenance of the oil cylinder when a failure occurs in the oil cylinder.

[0033] In one embodiment, a sealing ring 9 is provided between the guide sleeve 8 and the piston rod 6; a sealing ring 9 is provided between the first piston 3 and the cylinder barrel 5 and between the second piston 2 and the guide tube 4. By providing the sealing ring 9, the sealing performance of the oil cylinder is ensured and the risk of oil cylinder leakage is reduced.

[0034] In one embodiment, the front end cover 7 and the guide sleeve 8 are connected by a threaded member, and the first piston 3 and the second piston 2 are connected by a threaded member. By connecting the front end cover 7 and the guide sleeve 8 and the first piston 3 and the second piston 2 by a threaded member, each component can be quickly disassembled and assembled during maintenance.

[0035] In one embodiment, internal threads are provided at the outlet positions of the first oil inlet / outlet hole 11 and the second oil inlet / outlet hole 12. The internal threads are provided to facilitate the sealing connection between the hydraulic oil pipe and the oil cylinder.

[0036] Another object of the utility model is to provide an anode shaping flattening machine, which adopts any of the above-mentioned special cylinders, and the special cylinder is externally installed on the anode shaping flattening machine. One end of the special cylinder close to the front end cover 7 is connected and fixed to the anode shaping flattening machine to facilitate maintenance of the special cylinder.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
