Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic press equipment, and specifically relates to a hydraulic press with multi-dimensional positioning. Background Art

[0002] A hydraulic press is a machine that uses liquid as the working medium to transfer energy to achieve various processes. In addition to being used for forging and forming, hydraulic presses can also be used for straightening, pressing, packing, briquetting, and pressing plates, etc. Hydraulic presses include hydraulic presses and oil presses. Those with water-based liquids as the working medium are called hydraulic presses, and those with oil as the working medium are called oil presses. The specifications of hydraulic presses are generally expressed by the nominal working force or nominal tonnage. Most of the hydraulic presses for forging are hydraulic presses with relatively high tonnage. To reduce the equipment size, this equipment is particularly suitable for various processes such as bending, forming, and flanging of parts with central loads. After being equipped with a blanking buffer device, it can also be used for punching and blanking processing. It is the first choice product in industries such as the shipbuilding industry, pressure vessel industry, and chemical industry. It is used for processes such as stretching, flanging, bending, and stamping of metal sheet parts, and can also be used for general pressing processes. Devices such as blanking buffers, knockout devices, and moving worktables can be added according to user needs. In addition to being used for forging and forming, three-beam four-column hydraulic presses can also be used for straightening, pressing, packing, briquetting, and pressing plates, etc. They can also be used for the pressing process of shaft parts, the calibration, swaging, and pressing process of profiles, and the bending, profiling, shaping, embossing, nesting, stretching, and pressing processes of sheet parts with plastic materials, such as operations like stamping, bending, and thin stretching. It can also engage in straightening, pressing, and the pressing and forming operations of plastic products and powder products. Because of its wide range of applications, it is also called a universal hydraulic press.

[0003] For example, the patent document with the publication number CN 219381736 U discloses a positioning tooling for a hydraulic press. T-shaped grooves are symmetrically and fixedly opened on the surface of the installation table. An installation plate is arranged on the top of the installation table. Sliding grooves are fixedly opened on both sides of the installation plate. A double-headed lead screw and a sliding rod are respectively arranged in the inner cavities of the sliding grooves. The surface of the double-headed lead screw is threadedly sleeved with a first sliding plate. The surface of the sliding rod is slidably sleeved with a second sliding plate. A placing table is fixedly connected between the second sliding plate and the first sliding plate. An installation groove is fixedly opened on the top of the placing table. A clamping assembly is arranged in the inner cavity of the installation groove. This utility model relates to the technical field of hydraulic presses. This positioning tooling for a hydraulic press solves the problem that when the hydraulic press strikes the workpiece, the extrusion force generated will cause the workpiece to deform, and some fixed-form positioning clamps cannot change their clamping distances following the deformation of the workpiece. Therefore, the deformed workpiece and the fixed clamping mechanism will squeeze each other, which will damage the fixed clamping mechanism and affect the processing of the workpiece.

[0004] However, during the actual use of this structure, due to the limitations of its own structure, it often can only adopt a simple top-down hydraulic production operation. During the production process, the hydraulic press equipment cannot perform a limiting operation for edge adaptation of the upper and lower molds that require hydraulic pressure, and cannot achieve a multi-dimensional positioning production operation for the upper and lower hydraulic molds. As a result, the equipment is prone to uneven upper and lower hydraulic pressures, affecting the final mold hydraulic production effect of the equipment. At the same time, the equipment cannot perform a multi-dimensional positioning operation for the entire side of the hydraulic mold, and cannot complete the hydraulic production operation of the hydraulic press with more stable limiting, unable to meet the daily use requirements. Therefore, it is urgent to design a multi-dimensional positioning hydraulic press to solve the above problems. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: The multi-dimensional positioning hydraulic press, through the set processing frame, top conical cover, bottom conical cover, upper annular cover, lower annular cover, upper hydraulic rod, lower hydraulic rod, pressure control unit, shunt valve seat, top delivery pipe, top liquid control valve seat, bottom delivery pipe, bottom liquid control valve seat, liquid injection valve port, liquid injection valve pipe, contraction cover frame, hydraulic seat, fitting top pad, limit rubber ring, limit elastic cover, storage ring groove, top docking ring, bottom docking ring, adjustment groove, positioning rubber ring, docking ring airbag and docking ring seat, can enable the equipment to perform stable hydraulic production operations for the hydraulic press to perform multi-dimensional positioning of the hydraulic die up and down. In the actual use process, the staff first vertically place the upper and lower dies that need to be hydraulically docked into the inside of the processing frame, and perform docking operations at the fitting top pads on the surfaces of the upper and lower hydraulic seats inside the processing frame at the upper and lower positions respectively. Then, control the pressure control unit to perform inflation operations at the upper and lower ends of the top conical cover and bottom conical cover, the upper annular cover and lower annular cover through the shunt valve seats at both ends, and cooperate with the liquid injection valve port and liquid injection valve pipe on the front. After inflation, the docking ring airbags inside the upper annular cover and lower annular cover can perform telescopic adjustment in an up and down docking manner.

After up and down docking, it can cooperate with the top docking ring and bottom docking ring to perform hydraulic operations for multi-dimensional positioning up and down, ensuring the hydraulic production effect of the final die, reflecting the practicality of the equipment design.

[0017] The hydraulic press with multi-dimensional positioning further improves the overall usage effect of the equipment through the set processing frame, movable arc door, side air inflation cover, front air inflation cover, back air inflation cover, pressure control unit, air control unit, shunt air seat, shunt grille, back top connection airbag, back top connection plate, front top connection airbag, front top connection plate, first sealing strip, handle groove, movable groove, side top connection airbag, side top connection plate, second sealing strip and movable shaft.

Moreover, the first sealing strips on both sides of the movable arc door in daily use can also be hermetically attached to the second sealing strips at both ends of the front of the processing frame. When the pressure control unit is started daily, the air control unit on the back of the pressure control unit can be started synchronously, and it can inflate through the back top connection airbag in the center of the back air inflation cover, so that the back top connection plate at one end passes through the movable groove on the back of the inner wall of the processing frame and is adaptively abutted against the back of the upper and lower molds. In addition, the shunt air seats and shunt grilles on both sides of the back air inflation cover can inflate the side air inflation covers on both sides of the processing frame and the front air inflation cover on the front of the movable arc door, enabling the side top connection airbag inside the side air inflation cover and the front top connection airbag inside the front air inflation cover to inflate and expand.

Thus, when the upper and lower molds inside the processing frame are performing up and down hydraulic operations, they can perform multi-dimensional positioning hydraulic operations in all directions on the side, reflecting the comprehensiveness of the equipment design.
