Description

Technical Field

[0001] This utility model belongs to the field of horizontal bending processing technology of reinforcing bars, and specifically relates to a horizontal bending processing unit for reinforcing bars that is adaptable to processing reinforcing bars of different lengths. Background Technology

[0002] For CNC horizontal bending equipment for reinforcing bars, it generally includes a fixed bending machine fixed 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. To accommodate reinforcing bars of different lengths, especially longer ones, auxiliary supports are usually installed between the two bending machines to prevent the middle of the reinforcing bar from sagging. The number of auxiliary supports is generally at least two. The drawback of existing technology is that multiple auxiliary supports are generally slidably mounted on the track component along with the movable bending machine. Once the height is adjusted, they are not separated from the track component under normal circumstances. For processing some relatively short reinforcing bars, because multiple auxiliary supports occupy a certain length of space between the fixed and movable bending machines, even when the fixed and movable bending machines are relatively close, it is impossible to accommodate the bending of these short reinforcing bars. 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 horizontal bending processing unit for steel bars that can be adapted to the processing of steel bars of different lengths.

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

[0005] A horizontal bending processing unit for reinforcing bars adapted to different lengths includes a movable bending machine and a track component fixed to the foundation, with the movable bending machine slidably connected to the track component. Two auxiliary supports, auxiliary support B and auxiliary support A, are sequentially arranged between the fixed and movable bending machines. Each auxiliary support includes a support base and a lifting plate. The support base is slidably connected to the track component, and the lifting plate is connected to the support base via a lifting mechanism. A reinforcing bar support roller is mounted on the lifting plate. The movable bending machine has an open receiving space ASI facing the fixed bending machine, and the fixed bending machine has an open receiving space ASI facing the movable bending machine. When the lifting plate of auxiliary support B is at its lower limit, it can be pushed into receiving space ASI; when the lifting plate of auxiliary support A is at its lower limit, it can be pushed into receiving space ASI.

[0006] Furthermore, the track component includes a rack; the movable bending machine includes a movable support, which is slidably connected to the track component; a motor is fixedly mounted on the movable support, and the output shaft of the motor is coaxially and fixedly connected to the gear, which meshes with the rack for transmission.

[0007] Furthermore, the movable support includes, from bottom to top, a movable base plate, a support column B, and a top frame B. The support column B is used to fix the movable base plate and the top frame B. On the side facing the fixed bending machine, the top frame B protrudes relative to the movable base plate in the shape of an "eaves". The space ASⅠ is formed below the protruding part of the top frame B.

[0008] Furthermore, the fixed bending machine includes a fixed support, which is fixedly connected to the foundation; the fixed support includes a fixed base plate, a support column A and a top frame A from bottom to top. The support column A is used to fix the fixed base plate and the top frame A. On the side facing the movable bending machine, the top frame A protrudes from the fixed base plate in the shape of an "eaves". The space ASⅡ is formed below the protruding part of the top frame A.

[0009] Furthermore, the lifting mechanism is a scissor lift mechanism.

[0010] The beneficial effects that this utility model can achieve are as follows: This technical solution provides an open receiving space ASI on the side of the movable bending machine facing the fixed bending machine, and an open receiving space ASIII on the side of the fixed bending machine facing the movable bending machine. Matching and setting up liftable auxiliary supports, when processing longer steel bars, the auxiliary supports are all raised to the upper limit and slid to a suitable position to support the steel bars; when processing shorter steel bars, if no auxiliary support is needed, the auxiliary supports can be lowered to the lower limit and pushed into the corresponding receiving space, shortening the distance between the fixed bending machine and the movable bending machine, and meeting the bending processing of shorter steel bars.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] A horizontal bending processing unit for reinforcing bars adapted to different lengths, such as Figure 1 and Figure 2 As shown, it includes:

[0023] The fixed bending machine 2 and the track component 1 are fixed on the foundation, and the movable bending machine 6 is slidably connected to the track component 1; two auxiliary supports are arranged between the fixed bending machine 2 and the movable bending machine 6, namely auxiliary support B3 and auxiliary support A4.

[0024] like Figure 1 , Figure 3 and Figure 5 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.

[0025] like Figure 2As shown, the fixed bending machine 2 includes a fixed support 201, which is fixedly connected to the foundation. The fixed support 201 includes a fixed base plate 2011, a support column A2012 and a top frame A2013 from bottom to top. The support column A2012 is used to fix the fixed base plate 2011 and the top frame A2013. On the side facing the movable bending machine 6, the top frame A2013 protrudes from the fixed base plate 2011 in the shape of an "eaves". The space ASⅡ is formed below the protruding part of the top frame A2013.

[0026] like Figures 2-4 As shown, the movable bending machine 6 includes a movable support 601. The movable support 601 includes a movable base plate 6011, a support column B6012 and a top frame B6013 from bottom to top. The support column B6012 is used to fix the movable base plate 6011 and the top frame B6013. On the side facing the fixed bending machine 2, the top frame B6013 protrudes from the movable base plate 6011 in the shape of an "eaves". The space ASI is formed below the protruding part of the top frame B6013. The movable base plate 6011 is provided with support rollers II 602 and III 603 at its front and rear, respectively. Support roller II 602 is supported by the top surface of the front guide bar 102, and support roller III 603 is supported by the top surface of the rack 103, allowing the movable bending machine 6 to move on the track component 1. A rear limiting roller H605 is provided below the movable base plate 6011. The front end of the rear limiting roller H605 rolls against the rear end of the rack 103 to limit the backward movement of the movable bending machine 6. A motor 606 is fixedly installed on the movable base plate 6011. The output shaft of the motor 606 is coaxially fixedly connected to the gear 607, and the gear 607 meshes with the rack 103 for transmission. Specifically, the teeth of the rack 103 are arranged on its front end surface, and the rear end of the gear 607 meshes with the teeth of the rack 103 for transmission, which can limit the forward movement of the movable bending machine 6 while transmitting power.

[0027] like Figure 5 and Figure 6As shown, the auxiliary support includes a support base 301 and a lifting plate 309. The support base 301 is slidably connected to the track component 1. The lifting plate 309 is connected to the support base 301 via a scissor-type lifting mechanism, the movement of which is driven by a cylinder 310. A support roller I 302 and a lower limit roller 305 are provided below the support base 301. The support roller I 302 rolls and supports itself on 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, restricting the auxiliary support from moving upwards away 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. The lifting plate 309 is equipped with a horizontally arranged rebar support roller 308, a vertically facing rebar front limiting post 306, and a rebar rear limiting post 307. The space between the rebar front limiting post 306 and the rebar rear limiting post 307 is used to restrict the forward and backward movement of the rebar to be processed. The rebar support roller 308 is used to support the rebar to be processed. The support base 301 is provided with a limiting block 312 at the front and rear, and a limiting screw 311 is screwed onto the limiting block 312. The limiting screw 311 is a hard limit for the downward movement of the auxiliary support.

[0028] When processing longer reinforcing bars, raise all auxiliary supports to their upper limit and slide them to a suitable position to support the reinforcing bars, such as... Figure 7 As shown.

[0029] When processing shorter steel bars, if no auxiliary supports are needed, the auxiliary supports can be lowered to their lower limit first. Figure 8 As shown; then, auxiliary support B3 is pushed into the receiving space ASⅠ, and auxiliary support A4 is pushed into the receiving space ASⅡ, as shown. Figure 9 As shown, this shortens the distance between the fixed bending machine 2 and the movable bending machine 6, thus satisfying the bending processing of shorter steel bars.
