Description

Technical Field

[0001] The utility model relates to the technical field of stamping, in particular to a scaffolding disc stamping device. Background Technique

[0002] The disc-type scaffolding is mainly composed of vertical poles, horizontal poles and diagonal poles. Among them, the vertical pole is welded by a steel pipe, a steel pipe sleeve and several discs. In the production process of the disc scaffolding, a stamping device is needed. Stamping is a forming processing method that applies external force to plates, strips, pipes and profiles by a press and a die, so that they produce plastic deformation or separation, thereby obtaining workpieces with the required shapes and sizes. The blanks for stamping are mainly hot-rolled and cold-rolled steel sheet doors and steel strips. By stamping, the structure of the material is changed to meet the requirements of different process scenarios.

[0003] During the long-term multiple stamping processes, the upper die may be prone to damage and needs to be replaced. Most of the upper stamping dies are of fixed structures and are fastened and screwed together. It is rather troublesome for operators to replace and disassemble them. Moreover, during the stamping process, the waste chips of the stamped plates are likely to fly out and easily injure the staff working beside. Therefore, in view of the above problems, we provide a brand-new scaffolding disc stamping device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a scaffolding disc stamping device to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A scaffolding disc stamping device includes a U-shaped workbench. The inner bottom surface of the U-shaped workbench is fixedly connected with a lower die. The top surface of the U-shaped workbench is fixedly connected with a hydraulic cylinder. The driving end of the hydraulic cylinder penetrates through the inner top surface of the U-shaped workbench and is fixedly connected with a receiving block. The middle part of the bottom surface of the receiving block is fixedly connected with an extension column. The bottom end of the extension column is fixedly connected with a plug-in shell. The outer wall of the plug-in shell is rotationally connected with an operation ring shell. The inside of the plug-in shell is slidably plugged with a plug-in rod. The bottom end of the plug-in rod is fixedly connected with an upper die. Both sides of the outer wall of the plug-in rod are provided with fitting grooves. Corresponding to the two fitting grooves on both sides of the outer wall of the plug-in shell, cross grooves are provided. The inner side surface of the plug-in shell is fixedly connected with two special-shaped blocks. The outer wall of the plug-in shell is fixedly connected with external rings above and below the cross grooves. The external rings are rotationally connected with the operation ring shell. Corresponding to the two cross grooves, fitting blocks are provided on the inner side surface of the external rings. Springs are arranged between the external rings and the fitting blocks.

[0007] Furthermore, one end of the spring 1 is connected to the outer wall of the corresponding outer connecting ring, and the other end of the spring 1 is connected to the outer wall of the corresponding fitting block.

[0008] Furthermore, an annular connection shell is arranged outside the plug-in shell, and both sides inside the annular connection shell are fixedly connected with limit connection plates.

[0009] Furthermore, the outer wall of the annular shell is threadedly connected with an outer shield.

[0010] Furthermore, auxiliary ear plates are fixedly connected to the lower sides of the outer wall of the operating ring shell, and limiting holes are provided on the separated sides of the two auxiliary ear plates. The upper shell body is fixedly connected to both sides of the bottom surface of the receiving block, and the lower shell body is slidably connected to the interior of the upper shell body. The bottom end of the lower shell body passes through the limiting hole and is fixedly connected to the top surface of the corresponding limiting connecting plate, and spring 2 is arranged inside the upper shell body and the lower shell body.

[0011] Furthermore, the outer walls of the two upper shells are each provided with a long groove, a coupling shell is fixedly connected to the upper portion of the outer wall of the lower shell corresponding to the long groove, and auxiliary handles are slidably connected to the interior of the two coupling shells.

[0012] Furthermore, a bracket for limiting the auxiliary handle is fixedly connected to the middle side of the outer wall of the extension column.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, through the coordinated arrangement of the receiving block, the extension column, the plug-in shell, the operating ring shell, the plug-in rod, the fitting groove, the cross groove, the special-shaped block, the external connecting ring, the fitting block and the spring one, the operator can quickly disassemble and assemble the upper pressing mold, which is convenient for replacing the damaged upper pressing mold. Different matching upper pressing molds can also be replaced to better expand the scope of application. Through the coordinated arrangement of the auxiliary ear plate, the limiting hole, the upper shell, the lower shell, the spring two, the annular shell and the limiting connecting plate, the operating ring shell can be limited to prevent rotation.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 5, in the embodiment of the present utility model, a scaffolding disc stamping device includes a U-shaped workbench 1. A lower pressing die 2 is fixedly connected to the inner bottom surface of the U-shaped workbench 1. A hydraulic cylinder 3 is fixedly connected to the top surface of the U-shaped workbench 1. The driving end of the hydraulic cylinder 3 penetrates through the inner top surface of the U-shaped workbench 1 and is fixedly connected to a receiving block 4. A central part of the bottom surface of the receiving block 4 is fixedly connected to an extension column 5. The bottom end of the extension column 5 is fixedly connected to a plug-in shell 6. An operating ring shell 7 is rotatably connected to the outer wall of the plug-in shell 6. A plug-in rod 9 is slidably inserted into the interior of the plug-in shell 6. The bottom end of the plug-in rod 9 is fixedly connected to an upper pressing die 8. Two fitting grooves 10 are arranged on both sides of the outer wall of the plug-in rod 9. Cross grooves 11 corresponding to the two fitting grooves 10 are arranged on both sides of the outer wall of the plug-in shell 6. Two special-shaped blocks 12 are fixedly connected to the inner side surface of the plug-in shell 6. Outer rings 13 are fixedly connected to the upper and lower parts of the outer wall of the plug-in shell 6 at the cross grooves 11. The outer rings 13 are rotatably connected to the operating ring shell 7. Fitting blocks 14 corresponding to the two cross grooves 11 are arranged on the inner side surface of the outer rings 13. Spring one 15 is arranged between the outer rings 13 and the fitting blocks 14. One end of the spring one 15 is connected to the outer wall of the corresponding outer ring 13, and the other end of the spring one 15 is connected to the outer wall of the corresponding fitting block 14.

[0025] During specific implementation, when the upper pressing die 8 needs to be installed, the plug-in rod 9 on the upper pressing die 8 is aligned with the plug-in shell 6 and inserted. After insertion, the operating ring shell 7 is rotated forward. Through the rotation of the operating ring shell 7, the special-shaped block 12 fixed to the inner wall of the operating ring shell 7 rotates in the provided cross groove 11. When the special-shaped block 12 rotates to the position of the fitting block 14, the fitting block 14 is pushed out. The pushed-out fitting block 14 enters the fitting groove 10 on the plug-in rod 9 corresponding to the provided cross groove 11, thereby limiting the plug-in rod 9 and completing the engagement. After the upper pressing die 8 is installed, the following provided auxiliary ear plates 16, limiting holes 17, upper shell 18, lower shell 19 and spring two 20 are used to limit the operating ring shell 7. Through the provided spring one 15, when the upper pressing die 8 needs to be disassembled, only the operating ring shell 7 needs to be rotated in the reverse direction, and the spring one 15 will drive the fitting block 14 to reset into the cross groove 11, thereby releasing the limit on the fitting groove 10. Through the provided outer rings 13, the spring one 15 can be fixedly connected to the fitting block 14. Corresponding notches for enabling the fitting block 14 to reset are provided on the two outer rings 13. Through the provided hydraulic cylinder 3, the installed upper die 8 can be driven to press downwards. The overall design enables the operator to quickly disassemble and assemble the upper pressing die 8, facilitating the replacement of the damaged upper pressing die 8. By replacing different matching upper pressing dies 8, the adaptation range can be better expanded.

[0026] Embodiment 1

[0027] As Figure 3As shown, in this embodiment, an annular shell 21 is disposed outside the plug shell 6, and limiting connecting plates 22 are fixedly connected to both sides of the inside of the annular shell 21, and an outer protective cover 23 is threadedly connected to the outer wall of the annular shell 21.

[0028] During specific implementation, the annular connecting shell 21 can be simply screwed together with the matching outer shield 23. When the upper pressing mold 8 uses the hydraulic cylinder 3 to press the plate on the lower pressing mold 2, the outer shield 23 can better block the waste debris generated by the plate during the pressing process to avoid the debris from splashing. The lower shell 19 described below can be connected through the limiting connecting plate 22.

[0029] like Figure 3 , 5 As shown, in this embodiment, auxiliary ear plates 16 are fixedly connected to the lower sides of the outer wall of the operating ring shell 7, and limiting holes 17 are provided on the separated sides of the two auxiliary ear plates 16. The upper shell 18 is fixedly connected to both sides of the bottom surface of the receiving block 4. The interior of the upper shell 18 is slidably connected to the lower shell 19. The bottom end of the lower shell 19 passes through the limiting hole 17 and is fixedly connected to the top surface of the corresponding limiting connecting plate 22. Spring 20 is provided inside the upper shell 18 and the lower shell 19.

[0030] During specific implementation, the lower shell 19 and the limiting connecting plate 22 can pass through the limiting hole 17 provided on the auxiliary ear plate 16. The upper shell 18, the lower shell 19, the spring 20 and the limiting hole 17 on the auxiliary ear plate 16 cooperate with each other, which can better prevent the plug-in shell 6 from rotating by itself and play a limiting role. The setting of the upper shell 18, the lower shell 19 and the spring 20 makes it convenient for subsequent staff to disengage the lower shell 19 from the limiting hole 17.

[0031] Embodiment 2

[0032] like Figure 3 As shown, in this embodiment, the outer walls of the two upper shells 18 are provided with long grooves, and a coupling shell 24 is fixedly connected to the corresponding long groove on the upper side of the outer wall of the lower shell 19, and the interiors of the two coupling shells 24 are slidably connected with auxiliary handles 25, and a bracket 26 for limiting the auxiliary handles 25 is fixedly connected to the middle side of the outer wall of the extension column 5.

[0033] During specific implementation, through the coordinated setting of the long groove in the upper shell 18 and the auxiliary handles 25 of the coupling shell 24, the staff can easily drive the upper shell 18 to pull up, and through the setting of the bracket 26 on the outer wall of the extension column 5, the auxiliary handles 25 can be clamped, freeing up the staff's hands to disassemble the upper pressing mold.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
