DETAILED DESCRIPTION

[0022] The following will be combined with the appended examples in the embodiment of the present invention Figure 1 ~Attached Figure 3 , the technical solutions, structural features, achieved objectives and effects in the embodiments of the present utility model are described in detail.

[0023] It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions. They are only used to conveniently and clearly assist in explaining the implementation methods of the present invention, and are not used to limit the conditions for the implementation of the present invention. Therefore, they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in the present invention without affecting the efficacy and purpose that can be achieved by the present invention.

[0024] It should be noted that, in the present invention, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus comprising 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 apparatus.

[0025] The utility model provides an integrated single-arm hydraulic press, which includes:

[0026] 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 provided at the bottom of the piston rod 2 and is used for processing components;

[0027] The hydraulic press passage platform 5 is disposed below the hydraulic press body. A pressure head passage 4 corresponding to the hydraulic press pressure head 1 is formed 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 in and out of the pressure head passage 4. The hydraulic press passage platform 5 is a fixed component, for example, it is fixedly mounted on an installation platform, and is a non-movable component.

[0028] The hydraulic press workbench 6 is arranged below the ram passage 4 of the hydraulic press passage platform 5 in correspondence with the hydraulic press body (hydraulic press ram 1). The hydraulic pump 3 can control the piston rod 2 to drive the hydraulic press ram 1 in and out of the ram passage 4, so that the hydraulic press ram 1 can process the structure on the hydraulic press workbench 6.

[0029] The base 7 is arranged below the hydraulic press workbench 6, is fixedly connected to the hydraulic press workbench 6, and is 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; to prevent the connector 8 from being too close to the pressure head passage 4, which will cause the hydraulic press workbench 6 to be subjected to the force from the hydraulic press pressure head 1, and react 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] Multiple buffer assemblies, each of which is connected to the intermediate assembly, each of which is connected to the hydraulic press access platform 5 through a plurality of connectors 8, and each 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 is connected to the middle assembly and carries the remaining components of the buffer assembly;

[0036] A plurality of vertical plates 76 are vertically and parallelly arranged on the lower slot plate 71, and each 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 equidistant 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 . The upper side of the upper cover plate 75 is connected to the hydraulic press passage platform 5 via a plurality of connectors 8 .

[0038] In a preferred embodiment, as previously described, even if the connector 8 maintains a certain distance from the ram passage 4, when the hydraulic press worktable 6 is subjected to the force from the hydraulic press ram 1, the force reacts on the press passage platform and the connector 8 through the connector 8, and there is still a possibility that the entire device will become unstable. In order to further reduce this negative impact, any of the buffer components also includes:

[0039] A plurality of reinforcing plates 77 are provided, 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 can 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 includes a bottom plate 722 and two connecting plates 721 connected at 90 degrees to the ends of the bottom plate 722. The two opposite sides of each connecting plate 721 are connected to the lower slot plate 71 of each buffer assembly. The hydraulic press workbench 6 is disposed above the intermediate mounting plate 72, and the edges of the hydraulic press workbench 6 are connected to the upper edges of each vertical plate 76.

[0043] The middle card slot plate 79 has two ends respectively passing through the 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] Here, three types of connection points are formed, 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 workbench 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 intermediate 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 workbench 6 and the upper end edge of the vertical plate 76 are all connected to each other by designing card slots of a size appropriate to the parts to be positioned.

[0046] Specifically, an upper slot 74 is provided on the upper edge of each vertical plate 76, and a middle slot 73 is provided on the side of each vertical plate 76. The edge of the hydraulic press worktable 6 is inserted into the upper slot 74 to securely connect the hydraulic press worktable 6. The side edge of the middle slot plate 79 is inserted into the middle slot 73 to securely connect the middle slot plate 79. In addition, a plurality of lower slots 78 are provided on each lower slot plate 71. The edges of the connecting plate 721 are inserted into each lower slot 78 to securely connect the connecting plate 721 to the lower slot plate 71. The principle here is that since the connection objects of the upper card slot 74, the middle card slot 73 and the lower card slot 78 are all side or edge positions, the dimensions and sizes of the upper card slot 74, the middle card slot 73 and the lower card slot 78 are set corresponding to the aforementioned side or edge positions to achieve the corresponding embedded fixed connection; 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 part 8, a steel pipe can be used, and the two ends of the steel pipe are 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.

[0048] The following are specific embodiments of the present invention. Figure 2 and Figure 3 As shown, the intermediate assembly is designed as follows: the intermediate mounting plate 72 is a U-shaped plate comprising a base plate 722 and two connecting plates 721 connected at 90 degrees to the ends of the base plate 722. The hydraulic press worktable 6 is fixedly connected to the upper sides of the connecting plates 721. Both connecting plates 721 have holes on their surfaces, and the ends of the middle card slot plate 79 pass through the holes on the surfaces of the two connecting plates 721 and are fixed above the base plate 722.

[0049] This embodiment adopts two buffer assemblies, and any of the buffer assemblies is designed as follows: a rectangular lower card slot plate 71 is adopted, and the vertical plates 76 are arranged vertically, parallel to each other and equidistantly on the lower card slot plate 71; 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 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 assembly, of which 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. By welding, the two upper cover plates 75 are fixedly connected to the hydraulic press passage platform 5 through steel pipes; thus, a structure is formed. 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.

[0052] Although the present invention has been described in detail through the above preferred embodiments, it should be understood that the above description should not be considered as limiting the present invention. After reading the above description, various modifications and alternatives to the present invention will be readily apparent to those skilled in the art. Therefore, the scope of protection of the present invention shall be defined by the appended claims.
