[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] See also Figure 1-6 The utility model provides a technical solution: a construction steel bar bending device, comprising: a workbench 1, a driving mechanism 2 is arranged at the center of the top of the workbench 1, and also comprises: a feeding mechanism 4, and the feeding mechanism 4 is arranged at one end of the top of the workbench 1.

[0026] The feeding mechanism 4 includes a symmetrically arranged fixed frame 41, a movable frame 42 and a transmission member 410. The fixed frame 41 and the movable frame 42 are both rotatably connected with a plurality of conveying rollers 48. A motor 49 is fixedly installed in the workbench 1. The output shaft of the motor 49 passes through the workbench 1 and the fixed frame 41 and is fixedly installed at the bottom center of the conveying roller 48. The upper ends of adjacent connecting shafts in a group of conveying rollers 48 are connected through the transmission member 410.

[0027] The distance between the two sets of conveying rollers 48 is the same as the diameter of the steel bar to be bent. The transmission member 410 can be a combination of gears and chains or a combination of pulleys and belts. By starting the motor 49, several conveying rollers 48 are driven to rotate simultaneously with the assistance of the transmission member 410 to complete the conveying of the steel bars, reduce the manual burden, and improve the efficiency of steel bar bending.

[0028] The movable frame 42 is fixedly mounted with a slider 1 43 and a slider 2 45. The top of the workbench 1 is provided with a slide groove 1 44 and a slide groove 2 46 for the slider 1 43 and the slider 2 45 to slide. A clamping limit assembly 47 is provided in the slider 2 45.

[0029] The clamping limit assembly 47 includes a trapezoidal block 473, a plurality of limit blocks 475 and a cross bar 476. A slide groove 3 471 is provided in the center of the side of the slider 2 45 for the trapezoidal block 473 to slide. A spring 472 is fixedly welded in the slide groove 3 471. The trapezoidal block 473 is fixedly welded to one end of the spring 1 472. A plurality of slots 1 474 that match the trapezoidal block 473 are evenly and equidistantly provided on one side of the slot cavity of the slide groove 2 46. The limit blocks 475 are arranged at positions corresponding to the plurality of slots 1 474. The plurality of limit blocks 475 are fixedly connected by a cross bar 476. A slide groove 4 478 is provided on one side of the slot cavity of the slide groove 2 46 for the cross bar 476 to slide. A spring 2 479 is fixedly welded in the slide groove 478. One end of the spring 2 479 is fixedly welded to the center of one side of the cross bar 476 away from the limit block 475.

[0030] Under the sliding cooperation of slider 1 43 and slide groove 1 44, slider 2 45 and slide groove 2 46, the movable frame 42 slides on the workbench 1. During the sliding process, the trapezoidal clamping block 473 is subjected to the force to compress the spring 1 472 and slides into the slide groove 3 471. As the movable frame 42 slides, the trapezoidal clamping block 473 corresponds to the clamping groove 1 474 at different positions, and rebounds and is clamped in the clamping groove 1 474 at different positions under the action of spring 1 472, which will further adjust the distance value between the two sets of conveying rollers 48 to the same as the diameter value of the steel bar to be bent. At the same time, by setting a plurality of limit blocks 475, the limit blocks 475 are clamped in the corresponding clamping groove 1 474, that is, the trapezoidal clamping block 473 can be restricted from sliding from the clamping groove 1 474, that is, the movable frame 42 is fixed at this position, preventing the movable frame 42 from sliding, avoiding changing the distance value between the two sets of conveying rollers 48, and affecting the clamping and conveying of the steel bars.

[0031] A paddle 477 is fixedly installed at the center of the top of the crossbar 476, and a slide groove 4710 is provided on the top of the workbench 1 for the paddle 477 to slide, and a fixing component 5 is provided in the paddle 477;

[0032] When it is necessary to adjust the distance between the movable frame 42 and the fixed frame 41, the movable frame 42 needs to be slid, and the operator toggles the paddle 477, and the paddle 477 drives the cross bar 476 to slide in the slide groove 478, and at the same time compresses the spring 2 479, so that the paddle 477 slides out of the slot 1 474, so that the trapezoidal block 473 can slide out of the slot 1 474, and then adjust the distance between the two sets of conveying rollers 48 to the same as the diameter of the steel bar to be bent. The distance between the two sets of conveying rollers 48 can be adjusted according to the steel bars of different diameters to adapt to the bending processing of steel bars of different diameters.

[0033] Embodiment 2

[0034] The fixing assembly 5 includes a second clamping block 53, a first paddle 477 is provided with a sixth slide groove 51 for the second clamping block 53 to slide, a third spring 52 is fixedly welded in the sixth slide groove 51, one end of the third spring 52 is fixedly welded to the second clamping block 53, and a second clamping groove 54 is provided in the fifth slide groove 4710 for the second clamping block 53 to engage;

[0035] A second paddle 55 is fixedly mounted on the side of the second clamping block 53, and a sliding groove 7 56 is provided on the top of the first paddle 477 for the second paddle 55 to slide;

[0036] When the sliding paddle 477 is released, the limit block 475 slides out of the slot 474, and the block 2 53 installed on the paddle 477 slides to the slot 2 54. Under the action of the spring 3 52, the block 2 53 rebounds and is connected in the slot 2 54. Then, the paddle 477 is released, and the paddle 477 cannot rebound under the action of the block 2 53, so that the limit block 475 cannot rebound into the slot 1 474. The operator does not need to paddle the paddle 477 while sliding the movable frame 42, and the operation is simpler and more convenient. When the adjustment of the movable frame 42 is completed, the paddle 2 55 is paddled, and the paddle 2 55 drives the block 2 53 to slide out of the slot 2 54, so that the limit block 475 can rebound and be connected in the slot 1 474 under the action of the spring 2 479, preventing the movable frame 42 from sliding, avoiding changing the distance value between the two sets of conveying rollers 48, and affecting the clamping and conveying of the steel bars.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
