Description

Technical Field

[0001] This invention relates to the field of metal plastic forming equipment technology, and more specifically, to a hydraulic press suitable for the oscillating rolling process, particularly an oscillating rolling hydraulic press with an anti-lateral load structure. Background Technology

[0002] Oscillating rolling (or oscillating pressing) is a forming process with localized continuous loading, and it has important applications in the manufacturing of high-performance disc and shaft parts in aerospace, automotive, and energy fields. During oscillating rolling, a continuous, horizontal, unilateral strong eccentric load is generated between the die and the workpiece, causing significant asymmetrical deformation of the hydraulic press body and die system. Existing hydraulic presses mostly adopt symmetrical frame structures and lack specialized load-bearing and force transmission designs for horizontal eccentric loads, resulting in: The bending deformation of the fuselage column affects the accuracy of the slider movement; The mold may deflect or deform due to lateral forces, reducing mold life and molding quality; The machine lacks overall rigidity, making it difficult to meet the requirements of high-precision rolling processes.

[0003] Therefore, there is an urgent need for a swing roller hydraulic press that can effectively resist horizontal lateral loads and improve overall rigidity and mold support rigidity. Summary of the Invention

[0004] The present invention aims to provide a swaying hydraulic press with a lateral load-resistant structure to solve the problems of large deformation of the machine body and insufficient rigidity of the mold in existing swaying hydraulic presses under strong lateral load.

[0005] A rotary hydraulic press with a lateral load-resistant structure, characterized in that it comprises: Main frame system: tie rod (1), lock nut (2), upper cross beam (3), variable cross section column (5), workbench (10); the tie rod (1) passes through the upper cross beam (3), variable cross section column (5) and workbench (10), and its two ends are fixed by lock nut (2) and pre-tightened to form a closed pre-tightened frame; Drive system: The hydraulic cylinder (4) is installed in the upper crossbeam (3), and its piston rod is fixedly connected to the upper plane of the slider (6); Lateral load-resistant structures include: Variable cross-section column: The left and right widths of the variable cross-section column (5) gradually increase downward from the starting point of the effective stroke of the slider (6), forming a high cantilever rigid structure; The transverse tie rod force transmission mechanism includes a transverse tie rod (9), a transverse lock nut (7), and a transverse adjusting nut (8); the transverse tie rod (9) passes horizontally through the outer support (501) of the variable cross section column (5) located on the same side, and is fixed by the transverse lock nut (7) and the transverse adjusting nut (8), and is used to directly transmit the lateral load force borne by one side column to the other side column. Auxiliary anti-deviation mechanism: including auxiliary anti-deviation slider (11), column connecting beam (12) and auxiliary anti-deviation beam (13); The column connecting beam (12) is fixedly connected between two variable cross-section columns (5) on the same side; The auxiliary anti-eccentric beam (13) is located between the front and rear variable cross-section columns (5) on the same side. It is provided with boss keys (1302) at its upper and lower ends, which are inserted into the corresponding keyways on the column connecting beam (12) and the worktable (10) respectively, and positioned along the front and rear direction by flat keys (1303). The auxiliary anti-deviation slider (11) is fixed to the lower plane of the slider (6). One side of it is used to fit with the rolling die, and the other side forms a planar sliding guide pair with the guide plate (1301) on the auxiliary anti-deviation beam (13).

[0006] Furthermore, the lateral load on the auxiliary anti-eccentric beam (13) can be transferred to the variable cross-section column (5) on the other side in sequence through the column connecting beam (12) and the transverse tie rod (9), so as to realize the multi-path collaborative bearing of the whole machine.

[0007] The advantages of this invention are: 1. Enhanced local rigidity: The variable cross-section column design enhances the bending section modulus within the effective stroke area of ​​the slider, significantly improving the rigidity of the cantilever section of the column; 2. Optimize overall force transmission: The transverse tie rod enables the two columns to share the load on one side, avoiding the load concentration on the column on the stressed side and improving the overall machine's resistance to lateral load. 3. Improve mold stress: The auxiliary anti-eccentric slider and the anti-eccentric beam form an independent lateral support path, which directly transfers the eccentric load on the mold to the machine frame, suppresses mold deformation, and extends mold life; 4. Compact structure and easy to implement: By adding a few key components to the traditional hydraulic press structure, multiple anti-deviation functions can be achieved, and the cost is controllable.

Detailed Implementation

[0014] The patent will now be further described with reference to the accompanying drawings.

The upper crossbeam 3, the variable cross-section column 5, and the worktable 10 are fixed into a closed frame by the lock nuts 2 that are threaded to both ends of each pull rod 1. Before fixing the lock nuts 2, the pull rod 1 is pre-tightened so that the closed frame will not separate when the workpiece is pressed. The hydraulic cylinder 4 is fixedly installed in the upper crossbeam 3 through a step and a locking nut through a hole. The piston rod of the hydraulic cylinder 4 is fixedly installed on the upper plane of the slider 6. The width of the variable cross-section column 5 gradually increases from the starting point of the effective stroke of the slider 6, providing good cantilever rigidity. The transverse tie rod 9 passes horizontally through a hole on the outer support 501 of the variable cross-section column 5 on the same side, and is positioned and fixed by the transverse locking nut 7 and the transverse adjusting screw 8. When the slider 6 is subjected to a transverse eccentric load on one side, the transverse tie rod 9 directly transmits the load on the variable cross-section column 5 on that side to the variable cross-section column 5 on the other side. All variable cross-section columns on both sides... 5. Capable of simultaneously withstanding lateral eccentric loads, the swing roller hydraulic press possesses excellent overall rigidity; the column connecting beam 12 is located in the middle of the front and rear variable cross-section columns 5 on the left or right side, and is connected to the front and rear variable cross-section columns 5 on one side by bolts, and is positioned and fixed by horizontal flat key 1201 and vertical flat key 1202; the auxiliary anti-eccentric beam 13 is located in the middle of the front and rear variable cross-section columns 5 on the left or right side, and has boss keys 1302 machined at both ends of the auxiliary anti-eccentric beam 13, which are respectively inserted into the keyways machined on the column connecting beam 12 and the worktable 10 to achieve left and right positioning. The auxiliary anti-eccentric beam 13 is positioned front and back by a flat key 1303; the auxiliary anti-eccentric slider 11 is fixed to the lower plane of the slider 6. One side of the auxiliary anti-eccentric slider 11 is in contact with the oscillating die, and the other side forms a planar sliding guide with the guide plate 1301 on the auxiliary anti-eccentric beam 13. The auxiliary anti-eccentric slider 11 can transfer the lateral eccentric load on the oscillating die to the auxiliary anti-eccentric beam 13, thereby resisting the deformation tendency of the oscillating die under the action of the lateral eccentric load and improving the rigidity of the oscillating die. The load on the auxiliary anti-eccentric beam 13 can also be transferred to the variable cross-section column 5 on the other side through the column connecting beam 12 and the transverse tie rod 9.
