Description

Technical Field

[0001] This utility model relates to the field of building engineering equipment technology, and more specifically, to a steel bar bending device. Background Technology

[0002] In numerous fields such as construction and manufacturing, steel bars, as an important building material and structural component, often require bending to meet diverse application needs. Traditional steel bar bending methods primarily rely on manual operation or simple mechanical equipment. Manual bending of steel bars is not only labor-intensive and inefficient, but also difficult to guarantee bending accuracy, easily resulting in inaccurate bending angles and inconsistent bend shapes, failing to meet the requirements of high-quality projects. For projects requiring the bending of a large number of steel bars, manual operation can severely impact construction progress. While some existing steel bar bending machinery has improved bending efficiency to some extent, it suffers from limited functionality and poor flexibility. These devices often can only bend single steel bars, failing to meet the need for bending multiple bars simultaneously. This leads to repeated operations during mass production, wasting significant time and labor costs. Moreover, during the bending process, steel bars are prone to shifting, affecting bending quality and potentially causing equipment damage and safety accidents. Furthermore, some equipment has inadequate structural design, with insufficient stability in the load-bearing and restraint of the steel bars, resulting in uneven pressure distribution during bending, further affecting the bending effect and quality. Utility Model Content

[0003] The purpose of this invention is to provide a steel bar bending device that can effectively solve the problems in the prior art.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A rebar bending device includes: a frame; two lifting devices connected to the frame, the two lifting devices being connected to both ends of a bending pressure roller, the bending pressure roller being located in the middle of two rebar carrying rollers mounted side by side on the frame; and a limiting plate mechanism connected to the frame, the limiting plate mechanism being slidably connected to the two rebar carrying rollers to limit the two sides of the rebar to be bent placed between the bending pressure roller and the two rebar carrying rollers.

[0006] Furthermore, the lifting device includes: a lifting push rod fixed on the base plate of the frame, the output end of the lifting push rod being connected to a lifting frame, and the lifting frame being rotatably connected to the end of the bending pressure roller.

[0007] Furthermore, the lifting push rod is a hydraulic push rod or an electric push rod.

[0008] Furthermore, the lifting frame includes: a lower frame fixedly connected to the output end of the lifting push rod and an upper frame rotatably connected to the end of the bending pressure roller, with the upper frame and the lower frame connected by multiple bolts.

[0009] Furthermore, each of the two side plates of the frame is provided with a first guide slide opening with an open top, and the two ends of the bending pressure roller are slidably fitted in the two first guide slide openings.

[0010] Furthermore, the limiting plate mechanism includes: a transverse screw arranged parallel to the rebar bearing roller, the two ends of the transverse screw being fixed to the side plates on both sides of the frame, and multiple limiting plate assemblies connected to the transverse screw, with adjacent limiting plate assemblies forming a limiting zone for limiting the two sides of the rebar to be bent.

[0011] Furthermore, the limiting plate assembly includes: a limiting plate frame, which is slidably fitted on two steel bar bearing rollers, and a second guide slide opening with an open top is provided in the middle of the limiting plate frame, and a bending pressure roller is slidably fitted in the second guide slide opening; a screwing tube is rotatably connected to the limiting plate frame, and the screwing tube is threadedly connected to a transverse lead screw.

[0012] Furthermore, the side of the limiting plate frame is threaded with a limiting bolt, and the inner end of the limiting bolt abuts against the screw tube.

[0013] Furthermore, the outer surface of the limiting plate frame is polished.

[0014] The present invention provides the following beneficial effects:

[0015] In this utility model, a rebar bending device has a relatively long bending pressure roller and two rebar bearing rollers, and a limiting plate mechanism can limit the spacing of multiple rebars, enabling the device to simultaneously bend multiple rebars synchronously. Compared with the traditional single-rebar bending method, this greatly reduces the time spent on repetitive operations and improves the bending efficiency of the rebars. By limiting the two sides of the rebar to be bent through the limiting plate mechanism, the rebar can be prevented from shifting when the bending pressure roller is pressed down, ensuring the stability of the rebar's position during the bending process, making the bending angle and shape more accurate, and improving the bending quality of the rebars.

[0031] The following is in conjunction with the appendix Figure 1-7 The present invention will be described in further detail below.

[0032] Example 1

[0033] like Figure 1-7As shown, a rebar bending device includes: a frame 1; two lifting devices 2 are connected to the frame 1, and the two lifting devices 2 are connected to both ends of a bending pressure roller 3, the bending pressure roller 3 being located in the middle of two rebar carrying rollers 4 arranged side by side on the frame 1; a limiting plate mechanism 5 is connected to the frame 1, the limiting plate mechanism 5 being slidably connected to the two rebar carrying rollers 4 to limit the two sides of the rebar to be bent placed between the bending pressure roller 3 and the two rebar carrying rollers 4.

[0034] When bending reinforcing bars, the reinforcing bars are first placed between the bending pressure roller 3 and the two reinforcing bar bearing rollers 4, so that the reinforcing bars are below the bending pressure roller 3 and above the two reinforcing bar bearing rollers 4, and are supported by the two reinforcing bar bearing rollers 4. Then, the limiting plate mechanism 5 is adjusted to limit the two sides of the reinforcing bars to be bent, preventing them from shifting when the bending pressure roller 3 presses down to bend. After the reinforcing bars are installed, the two lifting devices 2 are started. When the two lifting devices 2 control the bending pressure roller 3 to move in detail, they can generate pressure on the position of the reinforcing bars to be bent, so that the reinforcing bars are bent. In addition, the bending pressure roller 3 and the two reinforcing bar bearing rollers 4 in this invention are relatively long, and the limiting plate mechanism 5 can limit multiple reinforcing bars at intervals, so that the reinforcing bar bending device of this utility model can simultaneously bend multiple reinforcing bars, which is beneficial to improving the bending efficiency of reinforcing bars.

[0035] Example 2

[0036] like Figure 1-7 As shown, the lifting device 2 includes a lifting push rod 201 fixed to the base plate of the frame 1. The output end of the lifting push rod 201 is connected to the lifting frame 202, and the lifting frame 202 is rotatably connected to the end of the bending roller 3. The lifting push rod 201 is a hydraulic rod or an electric push rod. The lifting frame 202 includes a lower frame fixedly connected to the output end of the lifting push rod 201 and an upper frame rotatably connected to the end of the bending roller 3. The upper frame and the lower frame are connected by multiple bolts. The side plates on both sides of the frame 1 are provided with a first guide slide 101 with an open top, and the two ends of the bending roller 3 are slidably fitted within the two first guide slides 101.

[0037] The lifting device 2 consists of a lifting push rod 201 and a lifting frame 202 fixed to the base plate of the frame 1. The lifting push rod 201 can be a hydraulic rod or an electric rod. When power is supplied to the lifting push rod 201 (hydraulic rods require hydraulic power, and electric rods require electricity), the output end of the lifting push rod 201 will extend and retract. Since the output end of the lifting push rod 201 is connected to the lifting frame 202, the extension and retraction of the lifting push rod 201 will drive the lifting frame 202 to move up and down. The upper frame of the lifting frame 202 is rotatably connected to the end of the bending roller 3, which allows the bending roller 3 to move up and down under the drive of the lifting frame 202. At the same time, the bending roller 3 itself can also rotate around its axis within the lifting frame 202. When the lifting push rod 201 pushes the lifting frame 202 downward, the bending roller 3 also moves downward, applying pressure to the steel bar to be bent located below it and above the two steel bar bearing rollers 4, thereby achieving the bending of the steel bar. During the bending process, due to the friction between the reinforcing bar and the surface of the bending roller 3, the bending roller 3 can rotate around its axis to adapt to the bending deformation of the reinforcing bar. The side plates of both sides of the frame 1 are provided with top-opening first guide slots 101. The two ends of the bending roller 3 are slidably fitted within the two first guide slots 101. The first guide slots 101 provide guidance for the up-and-down movement of the bending roller 3, ensuring that the bending roller 3 moves along a predetermined trajectory during lifting and lowering, thus guaranteeing the accuracy and stability of the pressure applied by the bending roller 3 to the reinforcing bar. The upper and lower frames of the lifting frame 202 are connected by multiple bolts. This detachable connection method facilitates the installation, debugging, and maintenance of the equipment. If the bending roller 3 or the lifting frame 202 malfunctions or requires replacement of parts, only the bolts need to be removed for operation, reducing equipment maintenance costs and time. Simultaneously, the rotating connection between the bending roller 3 and the lifting frame 202 allows the bending roller 3 to rotate flexibly during operation, reducing frictional resistance with the reinforcing bar and extending the service life of the bending roller 3.

[0038] Example 3

[0039] like Figure 1-7As shown, the limiting plate mechanism 5 includes: a transverse lead screw 501 arranged parallel to the rebar carrying roller 4, with both ends of the transverse lead screw 501 fixed to the side plates of the frame 1; multiple limiting plate assemblies 502 connected to the transverse lead screw 501; and a limiting zone for limiting the two sides of the rebar to be bent formed between adjacent limiting plate assemblies 502. Each limiting plate assembly 502 includes: a limiting plate frame 503, which is slidably fitted onto two rebar carrying rollers 4; a second guide slot 504 with an open top is provided in the middle of the limiting plate frame 503; the bending pressure roller 3 is slidably fitted into the second guide slot 504; and a screwing tube 505 is rotatably connected to the limiting plate frame 503, which is threadedly connected to the transverse lead screw 501. A limiting bolt is threadedly connected to the side of the limiting plate frame 503, with the inner end of the limiting bolt abutting against the screwing tube 505. The outer surface of the limiting plate frame 503 is polished.

[0040] When the position of the limiting plate assembly 502 needs to be adjusted, the screw tube 505 is rotated. Due to the threaded engagement between the screw tube 505 and the transverse screw 501, the screw tube 505 will move linearly along the transverse screw 501, thereby causing the connected limiting plate frame 503 to slide on the two rebar bearing rollers 4, thus adjusting the position of the limiting plate assembly 502. A limiting zone is formed between adjacent limiting plate assemblies 502. By adjusting the position of the limiting plate assembly 502, the width of the limiting zone can be changed to accommodate different specifications of rebars to be bent. The limiting plate frame 503 has a limiting bolt threaded on its side. After the limiting plate assembly 502 is adjusted to the appropriate position, the limiting bolt is tightened so that the inner end of the limiting bolt abuts against the screw tube 505. The friction prevents the screw tube 505 from continuing to rotate, thereby fixing the limiting plate assembly 502 in the corresponding position on the transverse screw 501, ensuring that the limiting plate assembly 502 will not move during the rebar bending process, and ensuring the limiting effect on the rebar to be bent. The limiting plate frame 503 has a second guide slide 504 with an open top in the middle, and the bending roller 3 slides within the second guide slide 504. During the bending process of the bending roller 3, the second guide slide 504 provides guidance for the bending roller 3, ensuring that the bending roller 3 can accurately apply pressure to the steel bar located in the limiting zone. At the same time, it also allows the limiting plate frame 503 to remain relatively stable in a suitable position as the bending roller 3 moves. The position of the limiting plate assembly 502 can be easily adjusted by rotating the screw tube 505, thereby changing the width of the limiting zone between adjacent limiting plate assemblies 502.

Similar or identical parts between embodiments can be referred to interchangeably. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.

[0042] It should also be noted that, in this specification, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
