Description

Technical Field

[0001] This utility model belongs to the field of horizontal bending processing technology of steel bars, and specifically relates to a CNC horizontal bending processing unit for uniformly supported steel bars. Background Technology

[0002] For CNC horizontal bending equipment for reinforcing bars, it generally includes a fixed bending machine anchored to the foundation and a movable bending machine. The distance between the two bending machines is adjusted by moving the movable bending machine to accommodate reinforcing bars of different lengths. For longer reinforcing bars, several auxiliary supports are typically installed between the two bending machines to prevent the middle of the reinforcing bar from sagging. In existing technology, the adjustment of the auxiliary support positions generally takes two forms: one is manual adjustment, which has a low degree of automation; the other is to set up a separate drive device for each auxiliary support, which is complex to control. Utility Model Content

[0003] The technical problem to be solved by this utility model is to make up for the shortcomings of the existing technology and provide a CNC horizontal bending processing unit for uniformly supported steel bars.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A uniformly supported CNC horizontal bending processing unit for reinforcing bars includes a movable bending machine and a track component fixed on the foundation, with the movable bending machine slidably connected to the track component. It also includes n auxiliary supports and an equally spaced variable-pitch mechanism, where n ≥ 2. The n auxiliary supports are equally spaced between the movable and fixed bending machines and slidably connected to the track component. Both the n auxiliary supports and the movable bending machine are connected to the equally spaced variable-pitch mechanism. Driven by the equally spaced variable-pitch mechanism, the n auxiliary supports support the reinforcing bars at n+1 equally spaced points.

[0006] Furthermore, the value of n is 2, and the two auxiliary supports are auxiliary support A and auxiliary support B from right to left.

[0007] Furthermore, the auxiliary support includes a horizontally arranged rebar support roller, a vertically arranged front rebar limiting post and a rear rebar limiting post, the space between the front rebar limiting post and the rear rebar limiting post is used to restrict the forward and backward movement of the rebar to be processed, and the rebar support roller is used to support the rebar to be processed.

[0008] Furthermore, the track component includes a rack; the movable bending machine includes a movable support, on which a motor is fixedly mounted, the output shaft of the motor is coaxially and fixedly connected to the gear, and the gear meshes with the rack for transmission.

[0009] Furthermore, the equal-spacing variable-pitch mechanism includes chain C, chain B, chain A, and a pair of sprocket mounting frames. The sprocket mounting frames are fixedly connected to the track component. Each sprocket mounting frame is fixedly mounted with a mounting shaft, on which a large sprocket, a medium sprocket, and a small sprocket are sequentially and coaxially fixedly mounted. The two large sprockets are driven by chain A, the two medium sprockets are driven by chain B, and the two small sprockets are driven by chain C. The movable bending machine is fixedly connected to chain A, the auxiliary support A is fixedly connected to chain B, and the auxiliary support B is fixedly connected to chain C. Driven by the motor, the movable bending machine moves closer to or further away from the fixed bending machine, thereby driving the auxiliary support A and auxiliary support B to move together. The transmission speed ratio of the large sprocket, medium sprocket, and small sprocket satisfies the requirement that the speed ratio of the movable bending machine, auxiliary support A, and auxiliary support B moving in the same direction is 3:2:1.

[0010] The beneficial effects that this utility model can achieve are as follows: n auxiliary supports are movably set on the track component, and the movement of the movable bending machine and the auxiliary supports on the track component is used to adapt to the processing of steel bars of different lengths; under the drive of the equidistant variable pitch mechanism, the n auxiliary supports move synchronously with the movable bending machine, so that the n auxiliary supports support the n+1 equidistant points of the steel bar to be processed, thereby achieving uniform support for the steel bar, with a high degree of automation and without increasing the difficulty of control.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] A uniformly supported CNC horizontal bending processing unit for reinforcing bars, such as Figure 1 and Figure 2 As shown, it includes:

[0022] Fixed bending machine 2 and track component 1, fixed to the foundation;

[0023] Auxiliary support B3, auxiliary support A4 and movable bending machine 6 are sequentially slidably connected to track component 1 in the left and right directions;

[0024] The equal-spacing variable-pitch mechanism 5 is used to drive the auxiliary support B3, auxiliary support A4 and movable bending machine 6 to move in the same direction, and to make the auxiliary support B3 and auxiliary support A4 support the three equal division points of the steel bar to be processed.

[0025] The specific structure is as follows:

[0026] like Figure 3 As shown, the track component 1 includes a pair of channel steels 101. The length direction of the channel steels 101 is left and right. The two channel steels 101 are arranged in front and behind. A front guide strip 102 is welded on the front channel steel 101, and a rack 103 is fixedly connected to the rear channel steel 101 by screws.

[0027] Auxiliary supports B3 and A4 have the same structure and are collectively referred to as auxiliary supports. The auxiliary supports include the main support body, such as... Figure 3As shown, the bottom of the support body includes a support base 301. Below the support base 301 are a support roller I 302 and a lower limit roller 305. The support roller I 302 rolls and supports the channel steel 101, allowing the auxiliary support to move on the channel steel 101. The top of the lower limit roller 305 rolls and abuts against the bottom surface of the rack 103, preventing the auxiliary support from detaching from the track component 1. A front limit roller 303 and a rear limit roller 304 are respectively provided at the front and rear parts below the support base 301. The rear end of the front limit roller 303 rolls and abuts against the front end of the front guide bar 102, and the front end of the rear limit roller 304 rolls and abuts against the rear end of the rack 103, restricting the back-and-forth movement of the auxiliary support. Figure 4 As shown, the top of the auxiliary support body is provided with a horizontally arranged steel bar support roller 308, a vertically arranged front steel bar limiting column 306 and a rear steel bar limiting column 307. The space between the front steel bar limiting column 306 and the rear steel bar limiting column 307 is used to restrict the forward and backward movement of the steel bar to be processed. The steel bar support roller 308 is used to support the steel bar to be processed.

[0028] like Figures 5-7 As shown, the movable bending machine 6 includes a movable support 601, on which a motor 606 is fixedly mounted. The output shaft of the motor 606 is coaxially and fixedly connected to a gear 607. The gear 607 meshes with a rack 103 for transmission. Specifically, the teeth of the rack 103 are arranged on its front end face, and the rear end of the gear 607 meshes with the teeth of the rack 103 for transmission. While transmitting power, the movable bending machine 6 can also be restricted from moving forward. Support rollers II 602 and III 603 are respectively provided at the front and rear of the movable bracket 601. Support roller II 602 is supported on the top surface of the front guide bar 102, and support roller III 603 is supported on the top surface of the rack 103, so that the movable bending machine 6 can move on the track component 1. A rear limiting roller H605 is provided below the movable bracket 601. The front end of the rear limiting roller H605 rolls against the rear end of the rack 103 to limit the movable bending machine 6 from moving backward. A connecting frame 604 is fixedly connected to the rear of the movable bracket 601. The connecting frame 604 is used to fixally connect to the chain A504 of the equal-pitch variable-pitch mechanism 5.

[0029] like Figures 6-8As shown, the equal-spacing variable-pitch mechanism 5 includes chain C502, chain B503, chain A504, and a pair of sprocket mounting brackets 501. The sprocket mounting brackets 501 are fixedly connected to the track component 1. Each sprocket mounting bracket 501 is fixedly mounted with a mounting shaft 508. A large sprocket 505, a medium sprocket 506, and a small sprocket 507 are coaxially fixedly mounted on the mounting shaft 508 in sequence. The two large sprockets 505 are driven by the meshing of chain A504, the two medium sprockets 506 are driven by the meshing of chain B503, and the two small sprockets 507 are driven by the meshing of chain C502. The movable bending machine 6 is fixedly connected to chain A504, the auxiliary support A4 is fixedly connected to chain B503, and the auxiliary support B3 is fixedly connected to chain C502. Driven by the motor 606, the gear 607 meshes with the rack 103, thereby driving the movable bending machine 6 to move closer to or away from the fixed bending machine 2, and in turn driving the auxiliary support A4 and the auxiliary support B3 to move together. The transmission speed ratio of the large sprocket 505, the medium sprocket 506 and the small sprocket 507 satisfies the requirement that the same-direction movement speed ratio of the movable bending machine 6, the auxiliary support A4 and the auxiliary support B3 is 3:2:1. In this way, when processing steel bars of different lengths, the auxiliary support B3 and the auxiliary support A4 can support the three equal division points of the steel bars to be processed, so as to achieve uniform support for the steel bars to be processed.
