[0024] It should be noted that, in the present invention, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only the elements explicitly listed, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0025] The present invention provides an integrated single-arm hydraulic press, the hydraulic press comprising:

[0026] The hydraulic press body; the hydraulic press body includes a hydraulic pump 3; a piston rod 2, the top of the piston rod 2 is connected to the hydraulic pump 3, and the hydraulic pump 3 can push the piston rod 2 to move in the vertical direction; a hydraulic press head 1, which is arranged at the bottom of the piston rod 2 and is used for processing components;

[0027] The hydraulic press passage platform 5 is arranged below the hydraulic press body. A pressure head passage 4 corresponding to the hydraulic press pressure head 1 is opened through the surface of the hydraulic press passage platform 5. The hydraulic pump 3 can control the piston rod 2 to drive the hydraulic press pressure head 1 to enter and exit the pressure head passage 4. The hydraulic press passage platform 5 is a fixed component, for example, it is fixedly arranged on a device platform, and is a non-movable component.

[0028] The hydraulic press workbench 6 is arranged below the pressure head passage 4 of the hydraulic press passage table 5 corresponding to the hydraulic press body (hydraulic press pressure head 1), and the hydraulic pump 3 can control the piston rod 2 to drive the hydraulic press pressure head 1 to enter and exit the pressure head passage 4, so that the hydraulic press pressure head 1 can process the structure on the hydraulic press workbench 6;

[0029] The base 7 is arranged below the hydraulic press workbench 6, fixedly connected to the hydraulic press workbench 6, and fixedly connected to the hydraulic press passage platform 5 through a number of connectors 8; it should be noted here that the connector 8 needs to maintain a certain distance from the pressure head passage 4; prevent the connector 8 from being too close to the pressure head passage 4, resulting in the hydraulic press workbench 6 being subjected to the force from the hydraulic press pressure head 1, which reacts to the hydraulic press passage platform 5 and the connector 8 through the connector 8, resulting in instability.

[0030] like Figure 2 and Figure 3 As shown, specifically, the base 7 includes:

[0031] An intermediate component, which is fixedly connected to the hydraulic press workbench 6;

[0032] A plurality of buffer components, any of which is connected to the intermediate component, any of which is connected to the hydraulic press passage table 5 through a plurality of connectors 8, and any of which is also connected to the hydraulic press workbench 6;

[0033] There is no direct contact between the buffer components, that is, each buffer component is independently connected to the intermediate component and the hydraulic press workbench 6.

[0034] The following will explain the intermediate components and buffer components one by one, such as Figure 2 As shown, any of the buffer components includes:

[0035] A lower card slot plate 71, connected to the middle assembly and carrying the remaining components of the buffer assembly;

[0036] A plurality of vertical plates 76, the vertical plates 76 are vertically and parallelly arranged on the lower slot plate 71, and any of the vertical plates 76 is connected to the intermediate component and the hydraulic press workbench 6; in a preferred embodiment, the vertical plates 76 are equidistantly arranged from each other;

[0037] An upper cover plate 75 is disposed above the plurality of vertical plates 76 , the lower side of the upper cover plate 75 is connected to all the vertical plates 76 , and the upper side of the upper cover plate 75 is connected to the hydraulic press passage platform 5 via a plurality of connecting members 8 .

[0038] In a preferred embodiment, as mentioned above, even if the connecting member 8 and the ram passage 4 are kept at a certain distance, when the hydraulic press worktable 6 is subjected to the force from the hydraulic press ram 1, the connecting member 8 reacts on the ram passage table and the connecting member 8, there is still a probability that the whole device will be unstable. In order to further reduce this negative impact, any of the buffer components also includes:

[0039] A plurality of reinforcing plates 77 , each of which is disposed in a space formed by adjacent vertical plates 76 and connected to adjacent vertical plates 76 , thereby achieving a reinforcing effect on the buffer assembly.

[0040] Furthermore, the part of the reinforcing plate 77 may be designed with a hollowed-out middle portion to enhance its buffering effect.

[0041] like Figure 3 As shown, the intermediate components include:

[0042] An intermediate mounting plate 72 is U-shaped, and the intermediate mounting plate 72 includes: a bottom plate 722, and two connecting plates 721 connected to the two ends of the bottom plate 722 at 90 degrees; the two opposite sides of any of the connecting plates 721 are connected to the lower card slot plate 71 of each buffer assembly, and the hydraulic press workbench 6 is arranged above the intermediate mounting plate 72, and the edge of the hydraulic press workbench 6 is connected to the upper end edge of each vertical plate 76;

[0043] The middle card slot plate 79 has two ends respectively passing through two connecting plates 721 and fixedly connected to the connecting plates 721, and is fixedly arranged above the bottom plate 722. The side edges of the middle card slot plate 79 are respectively connected to the side edges of each vertical plate 76;

[0044] There are three types of connection points formed here, namely, the connection points between the two connecting plates 721 of the middle mounting plate 72 and the lower card slot plate 71, the connection points between the middle card slot plate 79 and the side of the vertical plate 76, and the connection points between the edge of the hydraulic press worktable 6 and the upper end edge of the vertical plate 76.

[0045] In a preferred embodiment, the connection points between the two connecting plates 721 of the middle mounting plate 72 and the lower slot plate 71, the connection points between the middle slot plate 79 and the side of the vertical plate 76, and the connection points between the edge of the hydraulic press worktable 6 and the upper end edge of the vertical plate 76 are all connected to each other by designing slots of a size appropriate to the parts to be positioned.

[0046] Specifically, an upper slot 74 is provided at the upper end edge of any of the vertical plates 76, and a middle slot 73 is provided at the side of any of the vertical plates 76; the edge of the hydraulic press workbench 6 can be fixedly connected to the hydraulic press workbench 6 by being embedded in the upper slot 74; the side edge of the middle slot plate 79 can be fixedly connected to the middle slot plate 79 by being embedded in the middle slot 73. In addition, a plurality of lower slots 78 are provided on any of the lower slot plates 71, and the edge of the connecting plate 721 can be fixedly connected to the lower slot plate 71 by being embedded in each lower slot 78. The principle here is that, because the upper slot 74, the middle slot 73 and the lower slot 78 are connected to the side or edge positions, the size and size of the upper slot 74, the middle slot 73 and the lower slot 78 are set corresponding to the aforementioned side or edge positions, so that the corresponding embedded fixed connection can be achieved; the above is an explanation of all the components included in the base 7 of the present invention.

[0047] Regarding the selection of the connecting piece 8, a steel pipe can be used, and the two ends of the steel pipe can be welded to the hydraulic press passage platform 5 and the upper cover plate 75 respectively to achieve an integrated design; specifically, it can be selected according to actual conditions and is not limited here.

The surfaces of the two connecting plates 721 are both opened, and the two ends of the middle card slot plate 79 are respectively passed through the openings on the surfaces of the two connecting plates 721 and fixedly arranged above the bottom plate 722.

[0049] This embodiment uses two buffer components, and any of the buffer components is designed as follows: a rectangular lower card slot plate 71 is used, and the vertical plates 76 are vertically and parallelly arranged on the lower card slot plate 71 at equidistant distances; a lower card slot 78 is provided on each of the two side edges of the lower card slot plate 71 facing the middle mounting plate 72. It should be noted here that the position of the lower card slot 78 cannot be set in the middle of the vertical plate 76, resulting in a poor connection effect. In addition, an upper card slot 74 is provided on any of the vertical plates 76 corresponding to the upper end edge of the hydraulic press workbench 6, and a middle card slot 73 is provided on the side of the corresponding connecting plate 721. In addition, ten square reinforcement plates 77 are provided in the entire space formed by adjacent vertical plates 76 in a buffer component, and eight reinforcement plates 77 are hollow designs.

[0050] At this time, the design and assembly are carried out, the upper slot 74 is installed corresponding to the hydraulic press workbench 6, the middle slot 73 is installed corresponding to the middle slot plate 79; the lower slot 78 is installed corresponding to the edge of the connecting plate 721. At this time, the upper cover plates 75 are installed separately, and the two upper cover plates 75 are fixedly connected to the hydraulic press passage platform 5 through steel pipes by welding; thus, a Figure 1 An integrated single-arm hydraulic press is shown.

[0051] When the integrated single-arm hydraulic press is in operation, the hydraulic pump 3 can push the piston rod 2 to move in the vertical direction, thereby allowing the hydraulic press ram 1 to pass through the ram passage 4 to process the structure on the hydraulic press workbench 6 .
