Description

Technical Field

[0001] The present application relates to the field of metal bending, and in particular to a portable steel bar bending device. Background Art

[0002] As the skeleton of a building structure, the shape and direction of steel bars must adapt to the design of the overall structure. In some cases, in order to connect with other components, the steel bars need to be bent, so a steel bar bending device is usually required.

[0003] The manual rebar bending machine in the related technology is easy to carry. Its main structure includes a support plate and a turntable rotatably arranged thereon. A round rod is provided in the middle of the turntable. A limit plate close to the round rod is fixed on the support plate. A bending plate with a handle is fixed on one side of the turntable and can move with it and be used to assist in bending. The rebar is placed between the round rod and the limit plate and the bending plate. The handle is rotated to move the bending plate around the round rod to bend the rebar, which is more convenient for bending the rebar.

[0004] However, in the process of implementing the technical solutions in the embodiments of the present application, the inventors of the present application discovered that the above technology has at least the following technical problems:

[0005] The manual rebar bending machine in the above scheme is usually difficult to adjust the length freely due to the fixed round rod in the middle of the turntable and the limit plate and bending plate structure. Therefore, it is only suitable for bending rebars. It is not easy to bend steel plates of various sizes other than rebars, so its applicability is still relatively low. Summary of the Invention

[0006] In order to make up for the above shortcomings, the present application provides a portable steel bar bending device that can not only bend steel bars, but also effectively bend steel plates of various sizes.

[0031] The auxiliary bending member 3 includes a bending limiter A31 and a bending limiter B32 with the same structure and respectively provided on the support plate 1 and the connecting plate 24. The bending limiter B32 includes a U-shaped plate B322 that can move forward and backward, and an extension plate 324 with an outer surface flush with the U-shaped plate B322 is slidably fixed on the U-shaped plate B322.

[0032] In this embodiment, when bending steel bars, the positions of the bending limiter A31 and the U-shaped plate B322 in the bending limiter B32 are adjusted in advance according to the diameter of the steel bars. The bending limiter B32 can be moved to bend the steel bars between the movable rod 22 and the two U-shaped plates B322; and when it is desired to bend a steel plate of a wider size, the movable rod 22 is adjusted and fixed upward using the adjusting member 23, and then the height of the two extension plates 324 is adjusted upward, and then the bending limiter B32 is moved to bend the steel plate between the movable rod 22 and the two U-shaped plates B322, so that the application scope of this application is relatively wide.

[0033] See also Figures 1-4 The turntable 21 has a T-shaped longitudinal section, a circular opening is opened on the support plate 1 and a bearing is embedded therein, and the turntable 21 is fixed to the inner ring of the bearing. The bearing embedded on the support plate 1 facilitates the movement and rotation of the turntable 21.

[0034] See also Figures 1-4 The adjustment member 23 includes vertical rods 231 connected to both sides of the bottom end of the turntable 21. The bottom of the two vertical rods 231 is connected to a sleeve 232 for the movable rod 22 to pass through. The outer side of the sleeve 232 is connected to a protrusion 233. The protrusion 233 is screwed with an adjustment bolt A234 that extends into the inner cavity of the sleeve 232. The movable rod 22 is also provided with equidistant screw holes A221 that match the adjustment bolts A234. Specifically, the adjustment bolts A234 are loosened, and the movable rod 22 is pulled upward along the inner cavity of the sleeve 232 and the turntable 21 until it is pulled to the appropriate position. The adjustment bolts A234 are then tightened and fixed into the corresponding screw holes A221, thereby adjusting the position of the movable rod 22.

[0035] See also Figure 1 、 Figure 2 、 Figure 5-Figure 7The bending limiter A31 and the bending limiter B32 both include a U-shaped plate A321. The U-shaped plate A321 of the bending limiter A31 is fixed to one side of the upper surface of the support plate 1, while the U-shaped plate A321 of the bending limiter B32 is fixed to the connecting plate 24. Specifically, the bending limiter A31 and the bending limiter B32 are fixed at one position and can rotate and adjust with the turntable 21, which facilitates bending of steel bars or steel plates.

[0036] U-shaped plate B322 slides against the inside of U-shaped plate A321, with their openings facing each other. Adjustment bolts B323 are screwed onto U-shaped plate A321, the ends of which are rotatably connected to U-shaped plate B322. Specifically, rotating adjustment bolts B323 can cause U-shaped plate B322 to move inside U-shaped plate A321, thereby limiting the position of rebar or steel plates of different sizes.

[0037] A U-shaped groove 3221 is provided on the outside of the U-shaped plate B322. The extension plate 324 is designed in a U shape and is slidably arranged in the U-shaped groove 3221. An adjustment bolt C325 extending into the U-shaped groove 3221 is screwed into the inside of the U-shaped plate B322. Screw holes B3241 matching the adjustment bolts C325 are equidistantly provided on the back of the extension plate 324. Figure 5 and Figure 7 As shown, the cooperation of the U-shaped groove 3221 and the U-shaped extension plate 324 can be used to lengthen the U-shaped plate B322 with bending limit, and the cooperation of the adjusting bolt C325 and the screw hole B3241 can be used to limit the moved extension plate 324, thereby facilitating auxiliary bending of steel plates with wider sizes.

[0038] See also Figure 1 、 Figure 5 , the portable steel bar bending device also includes a handle member 5;

[0039] The handle member 5 includes an internally threaded barrel A51 fixed to the outer wall of the U-shaped plate A321 in the bending stopper B32. A handle 52 is screwed into the internally threaded barrel A51. One end of the handle 52 is provided with an external thread on the outside that matches the internally threaded barrel A51. An internally threaded barrel B53 that matches the handle 52 is fixed to one side of the lower surface of the support plate 1. Specifically, when in use, the handle 52 can be screwed into the internally threaded barrel A51 to increase the torque and bend the steel bar or steel plate more effortlessly. When not in use or when being carried out, the handle 52 can be screwed into the internally threaded barrel B53, which conveniently reduces the space occupied and makes it easier to carry.

[0040] See also Figure 1An L-shaped plate 4 is fixed to the other side of the lower surface of the support plate 1, and fixing holes are opened on the four sides of the bottom of the L-shaped plate 4. Specifically, the fixing holes on the L-shaped plate 4 can be used with external screws to fix the entire device to a certain bearing platform for easy bending operation.

[0041] When using this application:

[0042] When bending the steel bars, the adjusting bolt B323 is rotated according to the diameter of the steel bars to drive the U-shaped plate B322 to move inside the U-shaped plate A321, so that it can limit steel bars of different sizes. The handle 52 is turned to bend the steel bars between the movable rod 22 and the two U-shaped plates B322; and when you want to bend steel plates of wider sizes, loosen the adjusting bolt A234, pull the movable rod 22 upward along the inner cavity of the sleeve 232 and the turntable 21, pull it to the appropriate position, tighten the adjusting bolt A234 with the newly corresponding screw hole A221 to adjust the position of the movable rod 22, and then move the two extension plates 324 upward along the U-shaped groove 3221, and use the adjusting bolt C325 and the screw hole B3241 to position the moved extension plate 324, and turn the handle 52 to bend the steel plate between the movable rod 22 and the two U-shaped plates B322, so the application range of this application is wider.
