Description

Technical Field

[0001] This invention relates to a return device for a hydraulic press, specifically a return device for a cutter-type sponge titanium crushing hydraulic press, and more particularly to a flexible anti-torsion return device for a cutter-type sponge titanium crushing hydraulic press. Background Technology

[0002] Traditional cutter-type titanium sponge crushing hydraulic presses have their return hydraulic cylinders installed on both sides of the worktable, between the columns, occupying the openings on both sides of the press. This restricts the operator's space and prevents the addition of auxiliary devices to improve automation. Simply increasing the worktable size to expand the workspace would drastically increase manufacturing costs. Furthermore, the randomly falling titanium fragments after crushing can easily collide with the return hydraulic cylinders, causing structural damage. With the surging demand for titanium products, cutter-type titanium sponge crushing hydraulic presses need to improve automation, reduce failure rates, and enhance operator usability to achieve efficient production. Summary of the Invention

[0003] The purpose of this invention is to provide a flexible anti-torsion return device for a cutting-type sponge titanium crushing hydraulic press. Firstly, it achieves an upper-mounted arrangement of the return hydraulic cylinder, which effectively utilizes the opening space between the hydraulic press columns and prevents the return hydraulic cylinder from being damaged by falling titanium blocks after crushing. Secondly, under the strong off-center load condition of sponge titanium cutting and crushing, the return device has a good stress state and is not affected by the deformation of the hydraulic press body or the displacement of structural components, thus reliably ensuring the service life of the return device.

[0004] The technical solution of the present invention is as follows:

[0005] The main components include a return tie rod, a first locking nut, a return beam, a first adjusting nut, a second adjusting nut, a first pressure cap, a first disc spring, a first hollow ball joint, a second locking nut, a return hydraulic cylinder, a third adjusting nut, a second hollow ball joint, a second disc spring, a second pressure cap, and a third locking nut. A flexible anti-torsion return device for a cutter-type sponge titanium crushing hydraulic press has two return tie rods symmetrically arranged on both sides of the return hydraulic cylinder. The upper end of each return tie rod passes through a first adjusting nut, a return beam, and a first locking nut sequentially from bottom to top. The first adjusting nut and the first locking nut position and fix the upper end of the return tie rod to the return beam. The lower end of each return tie rod passes through a second adjusting nut and a first pressure cap sequentially from top to bottom. The system consists of a cover, a set of first disc springs, a hydraulic press slider, a first hollow ball joint, and a second locking nut. The second adjusting nut and the second locking nut position and fix the lower end of the return rod to the first cover, the first disc spring, the hydraulic press slider, and the first hollow ball joint. A gap exists between the return rod and the through hole in the hydraulic press slider. There is no surface contact between the upper side of the hydraulic press slider and the second adjusting nut. The first disc spring maintains the gap between the first cover and the hydraulic press slider, preventing any movement between the return rod and the hydraulic press slider. A first hollow ball joint is located between the lower side of the hydraulic press slider and the second locking nut. Therefore, there is a certain degree of tilting and offset freedom between the return rod and the hydraulic press slider. The allowable offset range of this degree of freedom is greater than the working range of the hydraulic press. The actual possible offset of the hydraulic press slider is measured to prevent the lower end of the return lever from being twisted when the hydraulic press slider offsets; the first pressure plate ensures that the inner ring of the first disc spring and the section with the same diameter as the return lever are spatially guided and fitted, and the inner stepped hole of the first pressure plate guides the outer ring of the first disc spring. At the same time, the first pressure plate limits the compression of the first disc spring to prevent the first disc spring from being damaged by overpressure; the return hydraulic cylinder is a plunger cylinder, and the cylinder body of the return hydraulic cylinder is fitted with the upper crossbeam of the hydraulic press through a hole. The cylinder body of the return hydraulic cylinder is connected and fixed to the upper plane of the upper crossbeam of the hydraulic press through a flange; the upper end of the return hydraulic cylinder plunger rod passes through the third adjusting nut, the second hollow ball joint, the return beam, the second disc spring, the second pressure plate, and the third locking nut in sequence from bottom to top. The third adjusting nut and The third locking nut positions and fixes the upper end of the return hydraulic cylinder plunger rod to the second hollow ball joint, the return beam, the second disc spring, and the second pressure plate. There is a gap between the return hydraulic cylinder plunger rod and the through hole of the return beam. There is no surface contact between the upper side of the return beam and the third locking nut. The second disc spring maintains the gap between the second pressure plate and the return beam, so that there will be no movement between the return hydraulic cylinder plunger rod and the return beam. The lower side of the return beam is provided with a second hollow ball joint between it and the third adjusting nut. Therefore, there is a certain degree of tilting and offset between the return hydraulic cylinder plunger rod and the return beam. The allowable offset range of the degree of freedom is greater than the actual possible offset of the return beam when the hydraulic press is working, thereby preventing the upper end of the return hydraulic cylinder plunger rod from being twisted when the return beam is offset.The second pressure cap ensures the spatial guiding engagement between the inner ring of the second disc spring and the section of the return hydraulic cylinder plunger rod with the same diameter. The inner stepped hole of the second pressure cap guides the outer ring of the second disc spring (13). At the same time, the second pressure cap limits the compression of the second disc spring, thereby preventing the second disc spring from being damaged by overpressure.

[0006] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0007] 1. The return hydraulic cylinder is installed on the upper crossbeam, thus leaving a clear space between the two columns on both sides of the hydraulic press, which facilitates worker operation and makes it easy to integrate automated auxiliary devices; in addition, the return hydraulic cylinder will not be hit by falling broken titanium blocks.

[0008] 2. The connection between the rod-shaped structural component of the return device and other structural components of the hydraulic press has local deflection freedom. The rod-shaped structural component will not be subjected to abnormal torque when the hydraulic press body deforms or the structural component shifts. The entire return device has a good stress state, low failure rate and long service life under strong off-center load conditions. Attached Figure Description

[0013] The invention will now be further described with reference to the accompanying drawings.

[0014] See Figure 1 , Figure 2The present invention mainly includes a return rod 1, a first locking nut 2, a return beam 3, a first adjusting nut 4, a second adjusting nut 5, a first pressure cap 6, a first disc spring 7, a first hollow ball joint 8, a second locking nut 9, a return hydraulic cylinder 10, a third adjusting nut 11, a second hollow ball joint 12, a second disc spring 13, a second pressure cap 14, and a third locking nut 15; a flexible anti-torsion return device for a cutter-type sponge titanium crushing hydraulic press has two return rods 1 symmetrically arranged on both sides of the return hydraulic cylinder 10, and the upper end of each return rod 1 passes through a first adjusting nut 4 from bottom to top. The return beam 3 and a first locking nut 2, along with the first adjusting nut 4 and the first locking nut 2, position and fix the upper end of the return rod 1 to the return beam 3. The lower end of each return rod 1 passes through a second adjusting nut 5, a first pressure plate 6, a set of first disc springs 7, a hydraulic press slider 2003, a first hollow ball joint 8, and a second locking nut 9 sequentially from top to bottom. The second adjusting nut 5 and the second locking nut 9 position and fix the lower end of the return rod 1 to the first pressure plate 6, the first disc spring 7, the hydraulic press slider 2003, and the first hollow ball joint 8. The return rod 1 and the hydraulic press slider... A gap is left between the perforations of block 2003, and there is no surface contact between the upper side of the hydraulic press slider 2003 and the second adjusting nut 5. The first disc spring 7 maintains the gap between the first pressure plate 6 and the hydraulic press slider 2003, thus preventing any movement between the return rod 1 and the hydraulic press slider 2003. A first hollow ball joint 8 is provided between the lower side of the hydraulic press slider 2003 and the second locking nut 9. Therefore, there is a certain degree of tilting and offset freedom between the return rod 1 and the hydraulic press slider 2003. The allowable offset range of this degree of freedom is greater than the actual possible movement of the hydraulic press slider 2003 during operation. The offset of the return lever 1 is reduced to prevent the lower end of the return lever 1 from being twisted when the hydraulic press slider 2003 is offset; the first pressure cover 6 ensures that the inner ring of the first disc spring 7 and the section with the same diameter as the return lever 1 are spatially guided and fitted; the inner stepped hole of the first pressure cover 6 guides the outer ring of the first disc spring 7; at the same time, the first pressure cover 6 limits the compression of the first disc spring 7 to prevent the first disc spring 7 from being damaged by overpressure; the return hydraulic cylinder 10 is a plunger cylinder, the cylinder body of the return hydraulic cylinder 10 is through-hole fitted with the upper crossbeam 2001 of the hydraulic press, and the cylinder body of the return hydraulic cylinder 10 is connected and fixed to the upper plane of the upper crossbeam 2001 of the hydraulic press through a flange;The upper end of the return hydraulic cylinder 10 plunger rod passes through the third adjusting nut 11, the second hollow ball joint 12, the return beam 3, the second disc spring 13, the second pressure cap 14, and the third locking nut 15 from bottom to top. The third adjusting nut 11 and the third locking nut 15 position and fix the upper end of the return hydraulic cylinder 10 plunger rod to the second hollow ball joint 12, the return beam 3, the second disc spring 13, and the second pressure cap 14. A gap is left between the return hydraulic cylinder 10 plunger rod and the through hole of the return beam 3. There is no surface contact between the upper side of the return beam 3 and the third locking nut 15, and the second disc spring 13 maintains the gap between the second pressure cap 14 and the return beam 3, so that no friction occurs between the return hydraulic cylinder 10 plunger rod and the return beam 3. To prevent axial movement, a second hollow ball joint 12 is provided between the lower side of the return beam 3 and the third adjusting nut 11. Therefore, there is a certain degree of tilting and offset between the piston rod of the return hydraulic cylinder 10 and the return beam 3. The allowable offset range of the degree of freedom is greater than the actual possible offset of the return beam 3 when the hydraulic press is working, thereby preventing the upper end of the piston rod of the return hydraulic cylinder 10 from being twisted when the return beam 3 is offset. The second pressure cover 14 ensures that the inner ring of the second disc spring 13 and the section with the same diameter as the piston rod of the return hydraulic cylinder 10 are spatially guided and fitted. The inner stepped hole of the second pressure cover 14 guides the outer ring of the second disc spring 13. At the same time, the second pressure cover 14 limits the compression of the second disc spring 13, thereby preventing the second disc spring 13 from being damaged by overpressure.

[0015] In practical application of this invention, the cutting-type sponge titanium crushing hydraulic press is generally equipped with two sets of flexible anti-twist return devices 1001. The cylinder body of the return hydraulic cylinder 10 is fixedly installed on the upper crossbeam 2001 of the hydraulic press. The lower ends of the two return tie rods 1 of each set of flexible anti-twist return devices 1001 are flexibly connected to the hydraulic press slider 2003. The piston rod of the return hydraulic cylinder 10 pushes the return beam 3 and then lifts the hydraulic press slider 2003 through the two return tie rods 1.
