DETAILED DESCRIPTION

[0026] The present application will be further described below in conjunction with the drawings and specific embodiments. The embodiments of the present application are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present application to the forms disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. Embodiments are chosen and described in order to best explain the principles of the present application and its practical application, and to enable others skilled in the art to understand the present application for various embodiments with various modifications as are suited to the particular use contemplated.

[0027] EMBODIMENT

[0028] Please refer to Figures 1-7 In the present embodiment, a bending device for metal processing is provided, which comprises a worktable 1, supporting legs 2 are installed at the four corners of the bottom of the worktable 1, a horizontal groove 3 is formed at the left side of the upper end of the worktable 1, a limiting mechanism 4 is installed in the horizontal groove 3, and a bending mechanism 5 is arranged at the right side of the upper end of the worktable 1. When it is necessary to bend the reinforcing steel bar, the reinforcing steel bar is first passed through the limiting mechanism 4, and then the bending part is placed in the bending mechanism 5. The limiting mechanism 4 has a limiting effect on the reinforcing steel bar, so that the part that does not need to be bent is kept in a straight state.

[0029] The limiting mechanism 4 can be adjusted according to the size (thickness) of the metal product (steel bar). The limiting mechanism 4 includes a lead screw 41, which is installed in the transverse groove 3 and rotatably connected to it. One end of the lead screw 41 passes through the side wall of the transverse groove 3 and is fixedly connected to the output shaft of the motor 42. The motor 42 is installed on the side wall of the worktable 1. When the motor 42 is started, it can drive the lead screw 41 to rotate. A slide block 43 is sleeved on the lead screw 41. The slide block 43 slides in the transverse groove 3. When the lead screw 41 rotates, the slide block 43 moves in the transverse groove 3. The position of the slide block 43 can be adjusted according to the length of the steel bar so that it can be adapted to the bending mechanism 5. A limiting seat 44 is threaded on the upper end of the slide block 43. The limiting seat 44 has an insertion hole. The steel bar is inserted into the insertion hole, and the insertion hole achieves the limiting. The limiting seat 44 with different inner diameters of the insertion hole can be replaced according to different steel bar specifications. The threaded installation method makes it easy to disassemble and replace, and the operation is convenient.

[0030] The bending mechanism 5 includes a turntable 51, which is installed in a groove 11 inside the worktable 1 and is rotatably connected to it. The bottom of the turntable 51 passes through the worktable 1 and is located below the worktable 1. A large gear 52 is installed at the bottom of the turntable 51, and the large gear 52 meshes with a small gear 53. The small gear 53 is installed on the output shaft of the second motor 54. The second motor 54 is fixed to the bottom of the worktable 1 by a bracket. After the second motor 54 is started, it can drive the turntable 51 to rotate in the groove 11 through the meshing action of the small gear 53 and the large gear 52. Thus, the two vertical rods 59 set on the turntable 51 can achieve the bending effect on the steel bars placed between them.

[0031] The turntable 51 has two symmetrical longitudinal grooves 55 at its upper end. A motor 3 56 is installed in the longitudinal groove 55. The motor 3 56 is a dual-shaft motor. Each of its two output shafts is connected to a lead screw 2 57. The end of the lead screw 2 57 is rotatably connected to the inside of the longitudinal groove 55. A slide block 2 58 is sleeved on the lead screw 2 57. The slide block 2 58 is slidably connected to the longitudinal groove 55. At the same time, a vertical rod 59 is provided at the upper end of the slide block 2 58. When bending the steel bar, the size of the gap between the two vertical rods 59 has an impact on the steel bar.

[0032] If the gap is too small, the steel bar may experience greater frictional resistance during bending, increasing the difficulty of bending. Too small a gap may also cause the steel bar to be excessively squeezed during bending, resulting in cracks or damage. However, when the gap is large, bending the steel bar in a large gap may result in inconsistent bending radii due to insufficient constraints, affecting the bending accuracy and overall structural performance of the steel bar. It may also cause the steel bar to shift or sway during bending, reducing the bending quality.

[0033] Therefore, different steel bars are bent according to specific specification requirements to select appropriate bending gaps, that is, the distance between the vertical rods 59 in the application, in the application, the motor three 56 is started, which can drive the screw rod two 57 to rotate, and then the slide seat two 58 on it is close to each other or away from each other, so as to drive the two vertical rods 59 to realize the adjustment of the gap, so as to adapt to the steel bending operation of different specifications or technical requirements, improve the quality of steel bending, and have good practical use value.

[0034] Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary skilled persons in the art and related fields without creative labor shall belong to the protection scope of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model are implemented according to conventional means in the art, unless otherwise specified and limited.
