DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] The bending limit assembly 2 can be used to fix and bend steel structures of different specifications. At the same time, the two cleaning blocks 212 can clean the surface of the steel structure when it moves through the limit groove, thereby improving the bending quality of the device. The length of the steel structure to be bent can be adjusted by the fixed length assembly 3 to meet the different bending lengths of the steel structure. The bending angle adjustment assembly 4 can control the different bending angles of the steel structure by moving the control column 48, thereby improving the practicality of the device.

[0028] like Figure 4 As shown, the bending limit assembly 2 includes a limit plate 21, the lower end of the limit plate 21 is fixedly connected to the right position of the rear upper end of the workbench 1, the upper end of the limit plate 21 is provided with a limit groove, the rear side of the limit plate 21 is threadedly connected with a fixing screw 23 that passes through the rear part of the inner wall of the limit groove, and the front end of the fixing screw 23 is fixedly installed with a fixing plate 22.

[0029] By rotating the fixing screw 23 , the fixing screw 23 drives the fixing plate 22 to move through the threaded connection with the limiting plate 21 , so that the fixing plate 22 fixes the part of the steel structure in the limiting groove.

[0030] like Figure 4 As shown, a mounting plate 24 is fixedly installed on the right rear side of the workbench 1, an electric push rod 25 is fixedly installed on the middle rear side of the mounting plate 24, the output end of the electric push rod 25 passes through the rear side of the mounting plate 24 and is fixedly installed with a connecting plate 26, and a plurality of linearly arranged bending rollers 27 are rotatably connected to the front side of the connecting plate 26.

[0031] The output end of the electric push rod 1 25 drives the connecting plate 26 to move, and the connecting plate 26 drives a plurality of bending rollers 27 to move and bend the fixed steel structure. The rotatable bending rollers 27 facilitate the loading work of the steel structure before bending.

[0032] like Figure 2 and Figure 4As shown, an adjustment groove 28 is provided at the rear position of the upper right part of the workbench 1, and a plurality of slots 29 arranged linearly are provided at the bottom of the inner wall of the adjustment groove 28. A cleaning rod 1 210 is plugged in and connected to the inner wall of the slot 29 near the front of the inner wall of the limiting groove, and a cleaning rod 211 is plugged in and connected to the inner wall of the slot 29 near the rear of the inner wall of the limiting groove. Cleaning blocks 212 are fixedly installed on the side of the outer walls of the cleaning rod 1 210 and the cleaning rod 2 211 that are close to each other.

[0033] When the steel structure passes through the limiting groove, the distance between the cleaning rod 211 and the surface of the steel structure is adjusted through the slot 29, so as to ensure that the two cleaning blocks 212 can clean the surface of the steel structure.

[0034] like Figure 5 As shown, the fixed-length component 3 includes an adjusting screw 31, and a storage groove is opened at the left position of the upper rear end of the workbench 1, the left and right ends of the adjusting screw 31 are rotatably connected to the inner wall of the storage groove, and the outer wall of the adjusting screw 31 is threadedly connected to a slider 32, and blocking plates 33 are fixedly installed on the left and right parts of the upper end of the slider 32, and a plurality of springs 34 arranged in a linear manner are fixedly installed on the opposite sides of the two blocking plates 33, and a reading rod 35 is fixedly installed on the upper front part of the slider 32, and a reading is engraved at the position of the upper end of the workbench 1 near the front part of the inner wall of the storage groove, and the reading rod 35 is located above the reading.

The reading rod 35 is moved to the specified position through the slider 32, and the steel structure is fixed in length due to the resistance of the blocking plate 33. A plurality of springs 34 can ensure that the contact end of the steel structure with the blocking plate 33 is not damaged when the steel structure is bent.

[0036] like Figure 6 As shown, the bending angle adjustment component 4 includes an electric push rod 41 and a rack 42. The outer wall of the electric push rod 41 is fixedly installed on the left lower end of the workbench 1, and a slide bar 43 is fixedly installed on the right end of the rack 42. The outer wall of the slide bar 43 is slidably connected to the inner wall of the right lower end of the workbench 1, and the left end of the rack 42 is fixedly connected to the output end of the electric push rod 41.

[0037] Through the output end of the electric push rod 2 41 , the rack 42 is moved below the workbench 1 through the slide bar 43 .

[0038] like Figure 3 and Figure 6 As shown, a mounting frame 44 is fixedly installed on the right lower end of the workbench 1, and a rotating shaft 45 is rotatably connected to the bottom of the inner wall of the mounting frame 44. A gear 46 is fixedly sleeved on the bottom of the outer wall of the rotating shaft 45. The outer surface of the gear 46 is meshed with the rear side of the rack 42, and a turntable 47 is fixedly sleeved on the top of the outer wall of the rotating shaft 45.

[0039] Through the movement of the rack 42 , the gear 46 drives the rotating disk 47 to rotate through the meshing action with the rack 42 .

[0040] like Figure 2 and Figure 6 As shown, an arc-shaped slide groove 49 is opened at the front of the upper end of the workbench 1, and a control column 48 is slidably connected to the inner wall of the arc-shaped slide groove 49. The lower end of the control column 48 is fixedly connected to the upper edge of the turntable 47. An angle number is engraved on the front position of the inner wall of the arc-shaped slide groove 49 at the upper end of the workbench 1. A designated rod 410 is fixedly installed on the bottom of the outer wall of the control column 48, and the designated rod 410 is located above the angle number.

[0041] Through the rotation of the turntable 47, the control column 48 moves in the arc-shaped slide groove 49, and the designated rod 410 moves to the designated angle through the control column 48 through the desired bending angle of the steel structure.

[0042] The working principle of the utility model is as follows: before the bending work of the steel structure, the length and angle of the steel structure to be bent are determined, and the adjusting screw 31 is first rotated, and the slider 32 moves by being threadedly connected with the outer wall of the adjusting screw 31 until the reading rod 35 moves to the specified position above the reading and stops rotating the adjusting screw 31, and then the electric push rod 41 is started, and the output end of the electric push rod 41 drives the rack 42 to move through the slide rod 43, and the gear 46 drives the turntable 47 to move by meshing with the rack 42, and the control column 48 slides in the arc-shaped slide groove 49 through the rotation of the turntable 47 until the designated rod 410 moves to a determined angle and stops moving.

[0043] The staff passes the steel structure through the limit groove until one end of the steel structure contacts the blocking plate 33. During the movement of the steel structure, the cleaning rod 211 is adjusted according to its actual size and inserted into the appropriate slot 29. The two cleaning blocks 212 can clean the surface of the steel structure and rotate the fixing screw 23. The fixing screw 23 drives the fixing plate 22 to fix the steel structure. Then the electric push rod 25 is started. The output end of the electric push rod 25 drives the connecting plate 26 to move. The connecting plate 26 drives several bending rollers 27 to bend the steel structure. During the bending process of the steel structure, the contact end with the blocking plate 33 has a strong effect. The thrust of the steel structure on the blocking plate 33 is converted into the elastic potential energy of the spring 34, thereby protecting the contact end of the steel structure and the blocking plate 33 from damage. Several bending rollers 27 push the steel structure until it contacts the outer wall of the designated rod 410, thereby realizing the bending work of the steel structure.
