Description

Technical Field

[0001] The invention relates to the technical field of hydraulic presses, in particular to a hydraulic press with a safety protection function. Background Art

[0002] A hydraulic press with safety protection function refers to the activity of a protection mechanism for objects, surrounding things, and workers during operation.

[0003] A hydraulic press is a piece of mechanical equipment that uses the static pressure of hydraulic oil delivered by an oil pump to process metal, plastic, rubber, wood, powder and other products.

[0004] The existing hydraulic presses have relatively simple protective functions, and there is still a risk factor during use. They cannot achieve an effective emergency stop effect and generally continue to apply pressure forward due to inertia. At the same time, most hydraulic presses are relatively bulky, occupy a large area, have low stability, and are not suitable for working in an environment with large temperature differences due to the impact on working performance. The hydraulic presses have low accuracy. Summary of the invention

[0005] A top beam, which has a square frame structure, a locking nut is fixedly connected to the top of the top beam, the locking nut penetrates the top beam and extends to the bottom side, a hydraulic cylinder is fixedly connected to the middle of the top of the top beam, a master cylinder valve is fixedly connected to the top of the hydraulic cylinder, a pipeline is fixedly connected to the middle of the top of the master cylinder valve, and a column is fixedly connected to the bottom of the locking nut; A support column assembly, the support column assembly also includes a support column, the bottom of the support column is fixedly connected to a movable crossbeam, the outer surface of the movable crossbeam is slidably connected to a column, the column passes through the movable crossbeam, and the bottom of the movable crossbeam is fixedly connected to a small support column; Four-post frame components, the number of which is four, and the tops of the four four-post frame components are all fixedly connected to the corners of the bottom of the top beam, and the bottom of the four-post frame shell is fixedly connected to a stabilizer; A shock absorber, the shock absorber having a circular structure, and the shock absorber is built into the bottom of the inner wall of the four-post frame assembly; A holding brake, the inner part of which is sleeved at the bottom end of the column; A workbench assembly, wherein the bottom of the stabilizer is fixedly connected to the workbench assembly, and the top of the workbench assembly is fixedly connected to the ejection cylinder assembly; The console comprises a console shell, an outer pull handle is fixedly connected to the middle of the outer surface of the console shell, a horizontal door is opened on the outer surface of the console shell, and a pressure gauge and a plurality of buttons are respectively installed on the top of the console shell.

[0006] Both the upper and lower sides of the support column are fixedly connected with fixing blocks. One side of the fixing block close to the top of the support column is fixedly connected to the bottom of the top beam. An auxiliary column is also fixedly connected between the opposite surfaces of the fixing blocks. A first spring is fixedly connected to the outer surface of the auxiliary column. An active slider is also fixedly connected at the opposite surfaces of the top beam and the active crossbeam. The column passes through the top beam and the active crossbeam through the active slider and extends to the outside, and the column is frictionally adapted to the active slider. Therefore, compared with the conventional four-column hydraulic press mode, there is an additional set of auxiliary column components. This set of components consists of multiple auxiliary columns, surrounding the support column, playing an auxiliary function, making the running track of the support column smoother during work, avoiding uneven force application and non-fitting tracks.

[0007] The small support column includes a central column, a concentric outer shaft and a gear. A central shaft is fixedly connected to the edge of the top of the central column. The outer surface of the central shaft and the inner surface of the concentric outer shaft are meshed through the gear. A connecting block is fixedly connected to the bottom of the central column. A second pressing block is fixedly connected to the bottom of the connecting block. A connecting rod is fixedly connected to the edge of the outer surface of the second pressing block. The top of the connecting rod is fixedly connected to the active crossbeam. A circular pressing block is fixedly connected to the bottom of the pressing block. Because a secondary pressing module is added at the conventional active crossbeam, when working, when the conventional extrusion reaches a certain degree, it needs to move up and down to a large extent. This module can achieve precise pressing when pressing small extrusions, and avoids the loss of hydraulic oil and reduces the friction between components.

[0008] The four-column frame assembly includes a four-column frame housing. A groove is opened inside the four-column frame housing. A column slide rail is fixedly connected to the middle of the inside of the groove. A circular slider is sleeved on the top of the column slide rail. The number of circular sliders is two, and the two circular sliders are respectively fixedly connected to the top of the inner wall of the four-column frame housing and the top of the guard plate. A connecting rod is fixedly connected between the two circular sliders. A third screw is fixedly connected to the bottom of the circular slider. The bottom of the third screw is fixedly connected to the top of the guard plate. An irregular rubber block is fixedly connected to the middle of the guard plate. Because a protection device is added outside the working area of the four-column hydraulic press. When the support column presses down, it can fall to the designated position faster than the support column, effectively avoiding some flying foreign objects from scattering when the hydraulic press crushes an object, and the guard plate is protected by an irregular rubber block, with a longer service life.

[0009] The shock absorber includes a shock-absorbing plate. A fourth connecting rod is fixedly connected to the bottom of the shock-absorbing plate. A fourth spring is fixedly connected to the outer surface of the fourth connecting rod. A shock-absorbing housing is fixedly connected to the bottom end of the fourth connecting rod. Because the guard plate descends quickly, in order to avoid a collision with the base due to too fast a speed, the shock absorber can help the guard plate reduce kinetic energy when descending, avoiding a violent collision effect.

[0010] The holding brake includes an arc-shaped block. Inside the arc-shaped block, a connecting rod and a second spring are respectively fixedly connected. A resistance piece is fixedly connected to the inner surface of the arc-shaped block. A connecting column is fixedly connected between the opposite surfaces of the arc-shaped block. The bottom of the arc-shaped plate is fixedly connected to a fixed bottom plate. The fixing piece is fixedly connected to the outer surfaces of the arc-shaped plate and the fixed bottom plate. A first screw is fixedly connected to the outer surface of the fixing piece. Since a set of holding brake modules are added at the bottom of the column, when there are misoperations during the use of the hydraulic press, or when objects and people are to be protected from impacts in a timely manner, the holding brake can immediately stop the movable crossbeam at a certain height.

[0011] On the outer surface of the top of the workbench assembly, a stabilizer and a column are respectively fixedly connected. The workbench assembly includes a workbench housing. Grooves are opened on both sides of the outer surface of the workbench housing. A second groove is opened inside the workbench housing. A slide rail is slidably connected to the bottom of the inner wall of the second groove. A support plate is slidably connected to the outer surface of the slide rail. Since a large-sized workbench is added, it can better bear the acting force of the support column. At the same time, compared with the previous separate layout of the instruments, there are slight adjustments. Instruments can be placed inside the workbench. When repairing, damaged parts can be quickly pulled out using the slide rail, reducing the occupied area of the hydraulic press.

[0012] The stabilizer includes a stabilizing module. A second connecting column is fixedly connected to the bottom of the stabilizing module. A third spring is fixedly connected to the outer surface of the second connecting column. A bolt plate is fixedly connected to the bottom of the stabilizing module. A second screw is threadedly connected to the outer surface of the top of the bolt plate, and the second screw is fixedly connected to the top of the workbench assembly through the bolt plate. Since a stabilizer is added at the bottom of the column, it is to make the fixed connection between the column and the ejector cylinder assembly more stable, greatly enhancing the awareness of safety protection. Moreover, it also increases the damping effect and can reduce the noise during the use of the hydraulic press.

[0013] The ejector cylinder assembly includes an ejector cylinder housing. The top of the ejector cylinder housing is fixedly connected to the inner wall of the ejector cylinder. The top of the inner wall of the ejector cylinder is fixedly connected to a damping component. The top of the damping component is fixedly connected to an outer plate of the ejector cylinder. A square groove is opened on the outer surface of the outer plate of the ejector cylinder, and a silica gel strip is fixedly connected in the middle. Since silica gel strips are added to some of the grooves opened in the ejector cylinder assembly, it is to increase the friction between the placed object and the ejector cylinder, better fixing the stability of the object, and also to make the support column apply force evenly when pressing down.

[0014] The damping assembly also includes a damping top plate and an outer wall, the bottom of the damping top plate is fixedly connected to a center column 2, the outer surface of the center column 2 is fixedly connected to a spring 5, the outer wall is sleeved on the outer surface of the center column 2, the bottom of the center column 2 is fixedly connected to a connecting plate, the bottom of the connecting plate is fixedly connected to a circular orifice plate, the bottom of the circular orifice plate is fixedly connected to the outer wall of the support column, the inner part of the outer wall of the support column is sleeved with a support column shaft, the outer surface of the central resistance wall is fixedly connected to the resistance wall, the orifice plate 2, and the outer surface of the circular orifice plate are fixedly connected to the bottom outer wall. By adding a damper to the ejection cylinder assembly, the continued downward pressure and jamming effect caused by overload when the support column is pressed down can be prevented, the upper limit of the pressure of the ejection cylinder assembly is increased, and the safety protection effect is increased.

[0015] The present invention provides a hydraulic press with a safety protection function. It has the following beneficial effects: 1. The hydraulic press with safety protection function changes the instability and ductility problem of the rapid downward movement of the supporting column connected to the movable crossbeam through the matching of the supporting column and the auxiliary column. The auxiliary column assists the supporting column to move downward, and the second track traction downward movement is carried out, which is more stable and ductile than before.

[0016] Second, the hydraulic press with safety protection function, through the fixed connection between the small support column and the movable crossbeam, adds a small support column structure to the original downward extrusion method of the movable crossbeam in a single operation mode. The concentric shaft and the concentric outer shaft can rotate in all directions through the meshing of gears, so that the pressure block and the circular pressure block can be repeatedly extruded at multiple angles. Because the operating components are small, the energy consumption is low.

[0017] 3. The hydraulic press with safety protection function has a four-column frame shell and a guard plate connected by a connecting rod. The guard plate moves up and down through the column slide rail. When the hydraulic press is working and an object is pressurized, the object splashes, and the guard plate can effectively intercept it. There are irregular rubber blocks on the guard plate to absorb energy and reduce shock, thereby protecting the operator.

[0018] Fourth, the hydraulic press with this safety protection function has a brake at the bottom of the column. When the movable crossbeam moves downward during the operation of the hydraulic press, an emergency stop is required. The brake contracts and clamps the connecting rod and spring between the arc blocks. There is also a resistance plate on the outer surface of the arc plate to increase friction and strengthen resistance for braking.

[0019] 5. The hydraulic press with safety protection function can work above the support column through the connection between the workbench and the control console. The built-in instruments can be operated inside the workbench, and the pressure gauge can be viewed by connecting to the control console. Compared with other forms, the integrated hydraulic press will save more space and have better safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Fixed blocks 24 are fixedly connected to both the upper and lower sides of the support column 25. One side of the fixed block 24 close to the top of the support column 25 is fixedly connected to the bottom of the top beam 3. An auxiliary column 21 is also fixedly connected between the opposite surfaces of the fixed blocks 24. A first spring 23 is fixedly connected to the outer surface of the auxiliary column 21. A movable slider 22 is also fixedly connected between the opposite surfaces of the top beam 3 and the movable cross beam 4. The column 17 penetrates through the top beam 3 and the movable cross beam 4 through the movable slider 22 and extends to the outside, and the column 17 is frictionally adapted to the movable slider 22. During operation, when the hydraulic press is started, the support column 25 moves downward, and the auxiliary column 21 moves downward together with the support column 25. The support column 25 is fixedly connected to the top of the movable cross beam 4, and the support column 25 pushes the movable cross beam 4 to move downward along the column 17. Compared with the mode of a conventional four-column hydraulic press, there is an additional set of auxiliary column assemblies. This set of assemblies consists of multiple auxiliary columns, surrounding the support column, playing an auxiliary function, making the running track of the support column smoother during operation, avoiding uneven force application and non-fitting tracks.

[0025] The small support column 9 includes a central column 91, a concentric outer shaft 93 and a gear 94. A central shaft 92 is fixedly connected to the edge of the top of the central column 91.

A circular pressing block 98 is fixedly connected to the bottom of the pressing block 97. Since a module for secondary pressing is added at the conventional movable crossbeam, when working, it needs to move up and down to a large extent after being pressed conventionally to a certain degree. This module can achieve precise pressing when pressing small extrusions, and avoids the loss of hydraulic oil and reduces the friction between components.

[0026] The four-column frame assembly 11 includes a four-column frame housing 111. A groove is formed inside the four-column frame housing 111. A column slide rail 117 is fixedly connected to the middle of the inside of the groove. A circular slider 113 is sleeved on the top of the column slide rail. The number of the circular sliders 113 is two, and the two circular sliders 113 are respectively fixedly connected to the top of the inner wall of the four-column frame housing 111 and the top of the guard plate 116.

When working, a column slide rail 118 is fixedly connected inside the four-column frame housing 111. The arc plate 117 moves up and down through the column slide rail 118. Since a protection device is added outside the working area of the four-column hydraulic press. When the support column presses down, it can fall to the designated position faster than the support column, so that when the hydraulic press rolls an object, some flying foreign objects can be effectively prevented from scattering, and the guard plate is protected by the irregular rubber block, and the service life is longer.

A spring four 124 is fixedly connected to the outer surface of the connecting rod four 123. The bottom end of the connecting rod four 123 is fixedly connected to a shock-absorbing housing 122. When working, when an external force presses on the shock-absorbing plate 121, the connecting rod four 123 and the spring four 124 work together to absorb the impact force.

When the electrical components inside the workbench housing 51 need to be repaired, the support plate 55 can be pulled out through the slide rail 54 for repair. Since a large-sized workbench is added, it can better bear the acting force of the support column. At the same time, compared with the previous separate layout of the instruments, there are slight adjustments. Instruments can be placed inside the workbench, and damaged parts can be quickly pulled out by using the slide rail during repair, reducing the occupied area of the hydraulic press.

A second screw 84 is threadedly connected to the outer surface of the top of the bolt plate 85, and the second screw 84 is fixedly connected to the top of the workbench assembly 5 through the bolt plate 85. Since a stabilizer is added to the bottom of the column, it is to more stably fix the connection between the column and the ejector cylinder assembly, greatly enhancing the awareness of safety protection, and also increasing the damping effect, which can reduce the noise during the use of the hydraulic press.

[0031] The ejector cylinder assembly 7 includes an ejector cylinder housing 71. A top of the ejector cylinder housing 71 is fixedly connected to an inner wall 72 of the ejector cylinder.

A square groove is formed in an outer surface of the outer plate 73 of the ejector cylinder, and a silica gel strip 74 is fixedly connected in the middle. During operation, when the support column assembly 2 moves downward and the pressure is too high, the damping assembly 13 fixedly connected to the inner wall 72 of the ejector cylinder will perform compressive stress relief. Since silica gel strips are added to some grooves formed in the ejector cylinder assembly, it is to increase the friction between the placed object and the ejector cylinder, better fix the stability of the object, and also to make the support columns apply force downward more evenly.

[0032] The damping assembly 13 further includes a damping top plate 1301 and an outer wall 1302. A bottom of the damping top plate 1301 is fixedly connected to a central column II 1303.

A resistance wall 1309 is fixedly connected to an outer surface of the central resistance wall 1310. A blocking block 1311 is fixedly connected to an outer surface of a bottom of the outer wall 1307 of the support column. A bottom of the blocking block 1311 is fixedly connected to a circular hole plate II (1313). A bottom outer wall 1312 is fixedly connected to an outer surface of the circular hole plate 1313. During operation, when an external force contacts the resistance top plate 1301, the central column 1303 and the spring V 1304 are guided downward, and the circular hole plate 1306 and the resistance wall 1309 are pressed against each other for fixed compression resistance. Since a damper is added to the ejector cylinder assembly, it can prevent continuous downward movement and jamming effects caused by overload during the downward pressure of the support column, increase the pressure-bearing upper limit of the ejector cylinder assembly, and increase the safety protection effect.
