[CN 201720877317.2] A Single Cylinder Reverse Double Plunger Hydraulic Cylinder
[CN 201720877317.2] A Single Cylinder Reverse Double Plunger Hydraulic Machine Cylinder Title: A Single Cylinder Reverse Double Plunger Hydraulic Machine Cylinder Application Number: CN 201720877317.2 Applicant: Dong Xiangyi Application Date: 2017-7-19 Patent Type: Utility Model The utility model discloses a single cylinder reverse double plunger hydraulic machine cylinder, including a main cylinder, which includes an oil cylinder sleeve, an oil cylinder head and a plunger, and the oil cylinder sleeve is provided with a through hole in a certain axial direction, the cylinder head is connected with the cylinder liner for blocking both ends of the through hole, one end of the plunger is arranged in the through hole and slidably connected with the inner wall of the cylinder liner, and the other end passes through the cylinder head and extends out of the cylinder liner. There are two plungers and they are arranged in opposite directions. The inner wall of the through hole between the two plungers and the end wall of the plunger enclose to form a hydraulic oil chamber. By setting the reverse double plunger, the utility model enables the single-cylinder hydraulic press to have double pressure capacity, ensures the pressure balance of the plungers on both sides, can work at the same time, and the applied pressure is the same, ensures the unity of the workpiece, and effectively improves the production efficiency, Save production costs.
