Problems solved by technology
Although this technical solution does not require a liquid filling device, it also brings other disadvantages: the main oil cylinder is installed on the movable beam, which not only brings new high requirements for the rigidity and strength of the movable beam, but also increases the speed of the fast oil cylinder. At the same time, the abnormal arrangement of the main oil cylinder also brings feasibility requirements to the overall layout design of the press. Therefore, this technical solution is difficult to implement due to the many difficulties to be overcome in the implementation process.

Embodiment Construction
[0029] Best practice:
[0030] refer to figure 1 , figure 2 , a large-tonnage hydraulic press with a fast stroke, including a press frame, a main cylinder 2, a fast cylinder 6, an upper movable beam 3, a lower movable beam 5, a guide mechanism for an upper movable beam, and a guide mechanism for a lower movable beam. The press frame includes Upper beam 1, lower beam 8 and column 7. The main oil cylinder body is installed on the upper beam 1, and its piston is connected with the upper movable beam 3. There are 2 fast oil cylinders 6 which are installed on both sides of the press respectively. A kind of clutch device 4 is installed between upper movable beam 3 and lower movable beam 5, and this clutch device 4 comprises upper and lower clutch blocks 42, 43 and a control device 44 for controlling one of the clutch blocks to move left and right, upper and lower clutch blocks 42, 43 are respectively mechanically connected with the upper movable beam 3 and the lower movable bea...

Disclosed is a large-tonnage hydraulic press with rapid stroke. A main cylinder is installed on an upper beam, a piston of the main cylinder is connected to an upper moving beam, one end of a rapid cylinder is connected to a lower moving beam, a clutch device is installed between the upper moving beam and the lower moving beam, the clutch device comprises an upper clutch block, a lower clutch block and a control device which is used for controlling one of the upper clutch block and the lower clutch block to move laterally, the upper clutch block and the lower clutch block are respectively connected to the upper moving beam and the lower moving beam in a corresponding mechanical mode, the clutch height between the upper clutch block and the lower clutch block corresponds to the auxiliary stroke completed by the rapid cylinder, the rapid cylinder drives the lower moving beam to complete the auxiliary stroke of a pressing machine, the distance between the lower moving beam and the upper moving beam which are pulled is filled by the clutch height, the main cylinder drives the upper moving beam, and the lower moving beam completes the working stroke under the drive of the clutch drive. The working stroke which is required to be completed by the main cylinder in the moving beams is 1 / 5 of the whole stroke, the stroke of the main cylinder is shortened, the installation and the maintenance are facilitated, and the production cost is greatly reduced.
Description
technical field [0001] The invention relates to a press using a hydraulic plunger, in particular to a large-tonnage hydraulic press with a fast stroke. Background technique [0002] Currently known large-tonnage presses (hereinafter referred to as presses) using hydraulic plungers are mainly composed of press frames, main oil cylinders, movable beams, movable beam guides and the like. The frame of the press can be a beam-column type or a frame type. The main oil cylinder is usually installed on the upper beam, and the piston is connected to the movable beam, and the main oil cylinder drives the movable beam to move up and down to achieve pressing and return. In order to meet the requirement of rapid empty stroke, a liquid filling valve is specially set up, which is connected with the liquid filling oil tank, and the control valve and the pump unit for controlling the liquid filling valve are also connected to the filling valve. During the rapid downstroke of the entire auxi...
