Technical Field

[0001] The invention relates to a multi-directional forging hydraulic press, in particular to an equal-strength integral composite-stroke multi-directional forging hydraulic press. Background Art

[0002] The multi-directional forging hydraulic press applies vertical and horizontal multi-directional pressing force to the workpiece, and the force on the machine body is superimposed in multiple directions, and the situation is complicated; under the premise of the same working table size, the internal working space opening size of the traditional multi-directional forging hydraulic press is much larger than that of the ordinary hydraulic press. This is to avoid vertical and horizontal stroke interference and solve the contradiction between unidirectional pressing and multi-directional pressing; the multi-directional forging hydraulic press generally also has vertical and horizontal perforation functions, and the perforation hydraulic cylinder needs to be connected in series with the pressing hydraulic cylinder. The above characteristics of the multi-directional forging hydraulic press make the structural size and mass of the machine body designed by the conventional scheme larger, which is more prominent for large tonnage and small table applications, resulting in excessive construction costs and mismatch between initial investment and output. How to reasonably reduce the structural size and occupied space to save materials and reduce costs is one of the main problems faced in the design of multi-directional forging hydraulic presses.

The piston rods of the horizontal return cylinders 10 are connected to the horizontal return plate 9. The output force of the horizontal return cylinders 10 acts on the horizontal workbench 11 through the horizontal return plate 9 and the horizontal guide rod 7; the horizontal workbench 11 completes horizontal left and right movement under the drive of the horizontal cylinders 8 and the horizontal return cylinders 10, and the horizontal guide rod 7 has a guiding effect on the movement of the horizontal workbench 11; the lower perforated cylinder 12 is fixedly installed in the workbench 306 of the equal-strength integral frame fuselage 3 through steps and vertical perforations of lock nuts.

[0018] See also Figures 1 to 3The main cylinder 1 of the present invention has a larger diameter, and the upper crossbeam 301 of the equal strength integral frame fuselage 3 extends front and rear and is wider than the rest of the fuselage to ensure sufficient strength; the lower half integral part 303 of the column of the equal strength integral frame fuselage 3 is wider than the left and right dimensions of the upper half open part 302 of the column, and the left and right dimensions of the workbench 306 of the equal strength integral frame fuselage 3 are also wider than the upper crossbeam 301.

[0020] When the hydraulic press is in the multi-directional forging working mode, the main cylinder 1 drives the slider 5 to press down, and the main cylinder 1 maintains pressure after the workpiece is punched upward to the required shape; then the horizontal cylinders 8 on both sides drive the horizontal workbench 11 to press the workpiece inward synchronously, and the horizontal cylinders 8 on both sides maintain pressure after the workpiece is punched left and right to the required shape. When the horizontal workbench 11 is pressed, it drives the horizontal guide rod 7 and the horizontal return plate 9 to move inward together, and at the same time, the piston rod of the horizontal return cylinder 10 is pushed and retracted by the horizontal return plate 9; during the pressure-maintaining process of the main cylinder 1 and the horizontal cylinder 8, the upper perforation piston rod 4 and the lower perforation cylinder 12 piston rod extend according to the process requirements, and push the perforation pin to complete the perforation on the workpiece.

[0021] When the hydraulic press is in the vertical unidirectional forging working mode, the piston rod of the horizontal return cylinder 10 extends and pushes the horizontal return plate 9 to move outward, thereby pulling the horizontal workbench 11 back to the rear limit position through the horizontal guide rod 7 installed on the horizontal return plate 9; then the master cylinder 1 drives the slider 5 to press down, and the horizontal workbench 11 enters the concave structure of the slider 5. After the workpiece is punched up to the required shape, the master cylinder 1 maintains the pressure; during the pressure maintaining process of the master cylinder 1, the upper perforating piston rod 4 and the lower perforating cylinder 12 piston rod extend according to the process requirements, pushing the perforating pin to complete the perforation on the workpiece; when the pressing is completed, the perforating piston rod retreats, and then the master cylinder 1 relieves the pressure, and finally the slider 5 retreats to the upper limit position driven by the return cylinder 2.
