[0026] Embodiment 1:

[0027] The utility model provides a bending device for steel structure production.

[0028] In one embodiment of the utility model, a bending device for steel structure production includes a mounting frame 1, a forming assembly and an adjusting assembly. A hydraulic cylinder 2 is arranged on the top of the mounting frame 1, and the piston rod of the hydraulic cylinder 2 vertically extends into the mounting frame 1 from top to bottom. The forming assembly includes a connecting rod 3, two pressure blocks 4 and a forming block 5. The connecting rod 3 is detachably connected to the piston rod of the hydraulic cylinder 2, and the two ends of the connecting rod 3 are detachably connected to the two pressure blocks 4 respectively. The two forming blocks 5 are respectively installed on the connecting rod 3 in a limited and movable manner. The adjusting assembly is arranged at the bottom of the mounting frame 1. The adjusting assembly includes two supporting blocks 6 that can approach or move away from each other, and the two supporting blocks 6 are both used to place the steel structure 7.

[0029] Specifically, if Figures 1 to 3As shown, in a bending device for steel structure production of the utility model, a hydraulic cylinder 2 is arranged on the top of the mounting frame 1, and the piston rod of the hydraulic cylinder 2 vertically extends into the mounting frame 1 from top to bottom and is detachably connected to the connecting rod 3 in the forming assembly, so that the connecting rod 3 can move up and down relative to the mounting frame 1 under the drive of the hydraulic cylinder 2, and the detachable connection between the connecting rod 3 and the piston rod of the hydraulic cylinder 2 can be a threaded connection, thereby facilitating the disassembly and assembly of the connecting rod 3 and facilitating maintenance and replacement. Furthermore, since the two ends of the connecting rod 3 are detachably connected to the two pressure blocks 4, and the two forming blocks 5 are respectively installed on the connecting rod 3 in a limited and movable manner, the hydraulic cylinder 2 can synchronously drive the two pressure blocks 4 and the two forming blocks 5 to move up and down; at the same time, the two forming blocks 5 can be installed on the connecting rod 3 in a limited and movable manner as a threaded connection, that is, the two forming blocks 5 are respectively slidably connected to the connecting rod 3, so that the two forming blocks 5 can slide relative to the mounting frame 1 along the extension direction of the connecting rod 3, and studs are installed on the forming blocks 5, and the studs are screwed to make them abut against the outer wall of the connecting rod 3, so that the two forming blocks 5 are limited and fixed, and the structural design is simple and reasonable.

[0030] It can be understood that when the steel structure 7 needs to be bent, the steel structure 7 is directly placed on the two supporting blocks 6 in the adjustment assembly. At this time, the part of the steel structure 7 that needs to be bent is located directly below the two forming blocks 5 and between the two supporting blocks 6. After the steel structure 7 is placed, the staff controls the hydraulic cylinder 2 to drive the two pressing blocks 4 and the forming blocks 5 to move downward, and the two pressing blocks 4 are respectively abutted against the steel structure 7, thereby realizing the clamping and limiting of the steel structure 7, effectively preventing the steel structure 7 from moving randomly during the bending process, and reliable use; with the continuous driving of the hydraulic cylinder 2, the two forming blocks 5 abut against the steel structure 7 and push the part that needs to be bent downward, thereby realizing the bending process of the steel structure 7, which is simple and convenient to operate. Furthermore, when the bending size of the steel structure 7 changes, by correspondingly adjusting the distance between the two forming blocks 5 and the two supporting blocks 6 and matching them with the bending size of the steel structure 7, the steel structure 7 can be bent into different sizes, thereby improving the flexibility of use of the utility model and being able to meet and adapt to the different bending requirements of the steel structure 7.

[0031] In one embodiment, a protrusion 8 is formed on any forming block 5 and a slot 9 is provided for the connecting rod 3 to extend into. A locking column 10 for contacting with the connecting rod 3 is provided on one side of any forming block 5 opposite to the slot 9. Figure 1 and Figure 3As shown, the forming block 5 can be installed by the engagement of the card slot 9 with the connecting rod 3, and the forming block 5 can slide on the connecting rod 3 relative to the mounting frame 1 to adjust according to the size of the steel structure 7 that needs to be bent; at the same time, when the forming block 5 is slid and adjusted into place, the locking column 10 is screwed to make it abut against the connecting rod 3 so that the forming block 5 can be limited and fixed, and the structural design is simple and reasonable. It is worth noting that in actual use of the utility model, several forming blocks 5 of the same size can be selected according to the diameter or width of the steel structure 7, and several forming blocks 5 are installed in a two-to-two connection manner, that is, two forming blocks 5 are connected and installed on the connecting rod 3 by bolts or screws, so that the bending requirements of the steel structure 7 can be better adapted to and met.

[0032] In one embodiment, specifically, Figure 1 As shown, a first scale 11 is provided on the connecting rod 3 along its extending direction, so that the staff can move and adjust the two forming blocks 5 accurately without the aid of measuring tools. The use is convenient and reliable, and the processing efficiency of the staff is improved.

[0033] In one embodiment, the adjustment assembly further includes a male mold 12, which is detachably mounted between the two supporting blocks 6, and a positioning block 13 is provided on the mounting frame 1. Figure 1 to Figure 2 As shown, when it is necessary to continuously bend the steel structure 7, the staff can install the punch 12 between the two supporting blocks 6. As the hydraulic cylinder 2 continuously drives the two forming plates to move downward and push the steel structure 7, the top surface of the punch 12 abuts against the part of the steel structure 7 between the two forming plates, so that the part of the steel structure 7 between the two forming plates cannot move downward, so that the steel structure 7 can be bent into a wavy line, and the continuous bending of the steel structure 7 as a whole is achieved after multiple bendings, which not only further improves the flexibility of the use of the utility model, meets the different bending requirements of the steel structure 7, but also improves the production efficiency of the steel structure 7, shortens the processing cycle, reduces the processing steps of continuous bending, reduces the labor intensity of the staff, and is reliable to use. It is worth noting that the specific shape and size of the punch 12 can be made according to the actual bending requirements of the steel structure 7, and the punch 12 should be made of high-strength and high-hardness materials to extend the service life of the punch 12 and prevent the punch 12 from deforming and failing after the steel structure 7 is subjected to batch continuous bending processing. In addition, the positioning block 13 is used to facilitate the installation of the punch 12 by the staff.

[0034] In one embodiment, the adjustment assembly also includes two mounting blocks 14 and an adjusting screw 15. The two mounting blocks 14 are symmetrically arranged relative to the punch 12. The two adjusting screws 15 are respectively passed through the two mounting blocks 14 and threadedly matched with the two mounting blocks 14. One end of the two adjusting screws 15 close to the punch 12 is detachably connected to the two supporting blocks 6 respectively, and the other end of the two adjusting screws 15 extends in a direction away from the mounting block 14 and is detachably mounted with a hand wheel 16.

[0035] Specifically, if Figures 1 to 3 As shown, when the bending size of the steel structure 7 changes, since the two mounting blocks 14 are symmetrically arranged relative to the punch 12, and the two adjusting screws 15 on the two mounting blocks 14 are detachably connected to the two supporting blocks 6 at one end close to the punch 12, the staff can screw the adjusting screws 15 to make the two supporting blocks 6 move closer or farther from each other to adapt to the bending size of the steel structure 7 and place and support the steel structure 7. At the same time, the staff can move and adjust the two forming blocks 5 according to the adjusted spacing between the two supporting blocks 6 or the bending size of the steel structure 7, thereby being able to perform bending processing of different sizes on the steel structure 7, and the operation is simple. In addition, since the other ends of the two adjusting screws 15 extend in a direction away from the mounting block 14 and are detachably mounted with a hand wheel 16, it is convenient for the staff to screw the adjusting screws 15, and no other disassembly tools are required, which is convenient to use.

[0036] In one embodiment, if Figure 1 and Figure 2 As shown, a second scale 17 is provided on the mounting frame 1 at positions corresponding to the two supporting blocks 6 along the extension direction of the adjusting screw 15, so that the staff can move and adjust the two supporting blocks 6 precisely without the aid of other measuring tools, thereby improving the processing efficiency of the staff.

[0037] In one embodiment, the mounting frame 1 includes a bottom plate 18, a top plate 19 and a plurality of columns 20, the plurality of columns 20 are vertically arranged on the bottom plate 18 and arranged in a rectangular array, the top plate 19 is detachably mounted on the top of the plurality of columns 20 and is used to mount the hydraulic cylinder 2, and the two pressing blocks 4 are slidably mounted between two adjacent columns 20. Specifically, Figure 1 and Figure 2 As shown, since a plurality of columns 20 are arranged in a rectangular array on the bottom plate 18, and the top plate 19 is detachably mounted on the top ends of the plurality of columns 20 and is used to mount the hydraulic cylinder 2, not only the overall structural strength of the utility model can be ensured, but also the multi-point support for the hydraulic cylinder 2 can be achieved, thereby effectively improving the support stability of the hydraulic cylinder 2; at the same time, by slidably mounting the two pressing blocks 4 between two adjacent columns 20, not only the overall structural strength of the utility model can be further provided, but also the linearity of the downward pushing of the two pressing blocks 4 and the forming block 5 can be ensured.

[0038] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
