Technical Field

[0001] The utility model relates to the technical field of steel processing, in particular to a steel bending machine. Background Art

[0002] Steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of components such as steel beams, steel columns, and steel trusses made of sections and steel plates. During the construction of steel structures, it is often necessary to bend steel such as angle steel.

[0003] However, the existing steel bending machines can only fix steel of one thickness, resulting in poor versatility. Moreover, they cannot measure the length of the bent part of the steel, leading to errors in the bent steel. Also, the situation of the steel being placed obliquely is likely to occur, which will also cause errors in the bent steel.

[0004] In view of the above problems, it is urgent to innovate and design on the basis of the original steel bending machine. Content of the Utility Model

[0005] The purpose of the utility model is to provide a steel bending machine to solve the problems raised in the above background art.

[0009] A measuring mechanism is arranged at one end of the fixing block away from the pressing mechanism;

[0010] The fixing mechanism includes a pressing plate. The pressing plate is located above the tabletop. A second rotating shaft is rotatably installed inside the pressing plate through a bearing. The lower end of the second rotating shaft is located inside the tabletop, and a first gear is fixed above the second rotating shaft.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. 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.

[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution: a steel bending machine, including a table 1, and a fixing block 3 is fixed on the top of the table 1 through a first bolt 2;

[0026] A pressing mechanism is arranged on one side of the top of the fixing block 3;

[0027] A fixing mechanism is arranged on the other side of the top of the fixing block 3;

[0028] A measuring mechanism is arranged at one end of the fixing block 3 away from the pressing mechanism;

[0029] The fixing mechanism includes a pressing plate 8. The pressing plate 8 is located above the table 1. A second rotating shaft 9 is rotatably installed inside the pressing plate 8 through a bearing. The lower end of the second rotating shaft 9 is located inside the table 1, and the upper end of the second rotating shaft 9 is fixed with a first gear 10 above the pressing plate 8. A third rotating shaft 11 is rotatably installed at the center of the top of the pressing plate 8 through a bearing. A second gear 12 is fixed on the outer wall of the third rotating shaft 11. The second gear 12 and the first gear 10 are meshed and connected. A crank 13 is fixed at the top of one side of the third rotating shaft 11. Both the second rotating shaft 9 and the first gear 10 are provided with four, and the second rotating shaft 9 is threadedly connected with the fixing block 3. By rotating the third rotating shaft 11 through the crank 13, the four second rotating shafts 9 can be rotated simultaneously, so that the four second rotating shafts 9 can drive the pressing plate 8 to move up or down, thereby being able to fix steel materials with different thicknesses and improving the versatility of the bending machine.

[0030] The pressing mechanism includes a support plate 4. A support plate 4 is fixed on one side of the top of the fixing block 3. A first rotating shaft 5 is rotatably installed between the support plates 4 through a bearing. An activity rod 6 is fixed on the outer wall of the first rotating shaft 5. A pressing rod 7 is fixed at the bottom of the activity rod 6. The activity rod 6 can drive the pressing rod 7 to rotate through the first rotating shaft 5.

[0031] The measuring mechanism includes a guide plate scale 14. One end of the fixed block 3 is fixed with a guide plate scale 14. A limit plate 15 is slidably arranged on the outer side of the guide plate scale 14. A second bolt 16 is threadedly installed at the top of the limit plate 15. Scale lines are provided at the top of the guide plate scale 14, and two guide plate scales 14 are symmetrically distributed about the central axis of the limit plate 15, enabling the limit plate 15 to slide on the two guide plate scales 14. When the end of the steel plate is in contact with one side of the limit plate 15, it can ensure that the steel plate is not placed obliquely, guaranteeing the accuracy of the steel plate bending, and the length of the bent part of the steel plate can be judged according to the scale lines at the top of the guide plate scale 14.

[0032] An anti - detachment plate 17 is fixed at the end of the guide plate scale 14, preventing the separation between the limit plate 15 and the guide plate scale 14.

[0033] Working principle: When using this steel - bending machine, first adjust the position of the limit plate 15 according to the length of the bent part of the steel required. Move the limit plate 15. When the left side of the limit plate 15 indicates a value on the scale line at the top of the guide plate scale 14 that is the same as the length of the bent part of the steel, rotate the second bolt 16. Since the second bolt 16 is threadedly connected to the limit plate 15, the second bolt 16 moves downward to contact the top of the guide plate scale 14, completing the fixation of the position of the limit plate 15.

[0034] Then place the steel plate on the top of the fixed block 3 and below the pressing plate 8, and make the end of the steel plate contact the left side of the limit plate 15. Then rotate the third rotating shaft 11 through the crank 13, so that the third rotating shaft 11 drives the second gear 12 to rotate. Then the second gear 12 drives four first gears 10 and four second rotating shafts 9 to rotate simultaneously. Since the second rotating shafts 9 are threadedly connected to the fixed block 3, the four second rotating shafts 9 drive the pressing plate 8 to move downward, completing the fixation of the steel.

[0035] Then rotate the movable rod 6 clockwise through the first rotating shaft 5. The movable rod 6 drives the pressing rod 7 to rotate clockwise, and the pressing rod 7 presses down the steel, causing the right end of the steel to bend.

[0036] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
