[CN 201721653651.6] Two-beam press


[CN 201721653651.6] Title of a two-beam press: Application number of a two-beam press: CN 201721653651.6 Applicant: Henan Zhengkai Yuan Machinery Technology Co., Ltd. Application date: 2017-12-1 Patent type: Utility model The utility model belongs to The field of mechanical design involves a two-beam press. The two-beam press is composed of a movable beam, a lower beam, several small oil cylinders and a hydraulic system. Each small oil cylinder needs to be flanged on the lower beam, while the upright column is formed by connecting the piston rods of each small oil cylinder with the movable beam through a connecting flange. The movement of the movable beam is completed by extending and retracting several small cylinders at the same time. Since the piston rods are concentric with the cylinder body itself, therefore, when the support holes of the movable beam and the lower beam are processed, the processing technology is much simpler and convenient for processing and use. Compared with the traditional press and the two-beam press of the same tonnage, their hydraulic systems are the same, except that the frame and the actuator are different. The two-beam press has fewer upper beams and uprights than the traditional press. The oil cylinder used by the two-beam press is smaller than that of the traditional press. The small oil cylinder is definitely more convenient to design, process and use than the large oil cylinder, thus saving the processing cost and reducing the processing technology.
