Description

Technical Field

[0001] This utility model belongs to the field of horizontal bending processing technology of steel bars, and specifically relates to a novel CNC horizontal bending processing unit for 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. To accommodate reinforcing bars of varying lengths, especially longer ones, at least two auxiliary supports are typically installed between the two bending machines to prevent the reinforcing bars from sagging in the middle. Existing technology has drawbacks including poor coordination between the auxiliary supports and the bending machines, and a low level of automation. 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 new type of CNC horizontal bending processing unit for steel bars.

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

[0005] A novel CNC horizontal bending unit for reinforcing bars includes a movable bending machine and a track component fixed to 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. Driven by the equally spaced variable-pitch mechanism, the n auxiliary supports support the n equally spaced points of the reinforcing bars to be processed. Both the movable and fixed bending machines are equipped with a material support frame, pneumatic clamps, and molds. The material support frame is used to horizontally support the reinforcing bars to be processed. The auxiliary supports include horizontal... The set rebar support roller and the rebar front limit post and rebar rear limit post that are vertically opposite to the rebar support roller are arranged in the same position as the opening formed by the rebar front limit post and the rebar rear limit post, the opening of the pneumatic clamp, and the opening of the mold, which are used to restrict the rebar from moving back and forth. The auxiliary support also includes a material dropping guide and a material removal component A that can swing in the vertical plane. The material removal component A is used to lift the rebar on the material support frame onto the material dropping guide and to remove the processed rebar from the mold. The material dropping guide is used to make the rebar fall into the opening formed by the rebar front limit post and the rebar rear limit post, and at the same time make the rebar fall into the opening of the mold.

[0006] Furthermore, the 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 through a lifting mechanism. The rebar support roller, the rebar front limit post, the rebar rear limit post, the material drop guide, and the material removal component A are all installed on the lifting plate.

[0007] Furthermore, the material removal component A is a single piece, comprising a hook portion A and a rod portion A connected sequentially from front to back. The hook portion A includes a horizontal plane, an inclined plane, and a vertical plane sequentially from front to back. The hook portion A is adapted to the position of the material dropping guide, and the rod portion A is adapted to the position of the opening formed by the front limiting post of the reinforcing bar and the rear limiting post of the reinforcing bar. The material removal component A is hinged to the lifting plate, and the swing of the material removal component A is driven by the cylinder B.

[0008] Furthermore, the material removal component A also includes a pry arm, which is connected to the rod A in an L-shape, and a hinge hole is provided at the connection between the pry arm and the rod A; the material removal component A is hinged to the lifting plate through the hinge hole and hinge shaft II, the cantilever end of the rod A is hinged to the piston rod B of the cylinder B through hinge shaft I, and the cylinder body B of the cylinder B is hinged to the lifting plate.

[0009] Furthermore, both the movable bending machine and the fixed bending machine are hinged with a material-lifting component B. The material-lifting component B can swing in the vertical plane. The material-lifting component B is an integral part, including a hook part B and a rod part B connected sequentially from front to back. The hook part B has the same shape as the hook part A and is positioned accordingly. The rod part B is positioned accordingly to the rod part A. The swinging of the material-lifting component B is driven by a cylinder C.

[0010] Furthermore, the value of n is 2, and the two auxiliary supports are auxiliary support A and auxiliary support B from right to left.

[0011] 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.

[0012] 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.

[0013] Furthermore, the movable bending machine has an open receiving space ASⅠ on the side facing the fixed bending machine, and the fixed bending machine has an open receiving space ASⅡ on the side facing the movable bending machine. When the lifting plate of the auxiliary support B is at the lower limit position, it can be pushed into the receiving space ASⅠ; when the lifting plate of the auxiliary support A is at the lower limit position, it can be pushed into the receiving space ASⅡ.

[0014] 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 an "eaves" shape, and the lower part of the protruding portion of the top frame B forms the receiving space ASⅠ. The fixed bending machine includes a fixed support, which is fixedly connected to the foundation. The fixed support includes, from bottom to top, a fixed base plate, a support column A, and a top frame A. 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 relative to the fixed base plate in an "eaves" shape, and the lower part of the protruding portion of the top frame A forms the receiving space ASⅡ.

[0015] The beneficial effects that this utility model can achieve are: the auxiliary support and bending machine have good synergy, which can not only achieve uniform support for the steel bars, but also achieve automatic feeding of the mold and automatic ejection of the finished product, with a high degree of automation.

Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0033] A novel CNC horizontal bending processing unit for reinforcing bars, such as Figures 1-2 As shown, the device includes a track component 1 and, from left to right, a fixed bending machine 2, an auxiliary support B3, an auxiliary support A4, an equal-spacing variable-pitch mechanism 5, and a movable bending machine 6. The track component 1 and the fixed bending machine 2 are both fixed on the foundation. The auxiliary support B3, the auxiliary support A4, and the movable bending machine 6 are all slidably connected to the track component 1. The equal-spacing variable-pitch mechanism 5 is used to drive the auxiliary support B3, the auxiliary support A4, and the movable bending machine 6 to move in the same direction, and to make the auxiliary support B3 and the auxiliary support A4 support the three equally spaced points of the steel bar to be processed.

[0034] like Figure 3As 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.

[0035] like Figure 12 As 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.

[0036] like Figure 12 As shown, the movable bending machine 6 includes a movable support 601. From bottom to top, the movable support 601 includes a movable base plate 6011, a support column B6012, and a top frame B6013. 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 relative to the movable base plate 6011 in an "eaves" shape, and a receiving space ASⅠ is formed below the protruding portion of the top frame B6013. Figure 5 and Figure 8 As shown, the front and rear parts of the movable base plate 6011 are respectively provided with support rollers II 602 and III 603. Support rollers II 602 are rolled and supported on the top surface of the front guide bar 102, and support rollers III 603 are rolled and 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 base plate 6011. The front end of the rear limiting roller H605 rolls and abuts against the rear end of the rack 103 to limit the movable bending machine 6 from moving backward. 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. The gear 607 meshes with the rack 103 for transmission. Specifically, the teeth of the rack 103 are set on its front end surface, and the rear end of the gear 607 meshes with the teeth of the rack 103 for transmission. At the same time as transmission, it can also limit the movable bending machine 6 from moving forward.

[0037] Both the movable bending machine 6 and the fixed bending machine 2 are equipped with a material support frame 608, a pneumatic clamp 610, and a die 609, such as Figures 5-6 As shown, the material support frame 608 is used to horizontally support the steel bars to be processed, the pneumatic clamp 610 is used to clamp the steel bars, and the mold 609 is used for bending the steel bars.

[0038] Auxiliary supports B3 and A4 have the same structure and are collectively referred to as auxiliary supports here. Figures 3-4 As shown, the auxiliary support includes a support base 301 and a lifting plate 309. The lifting plate 309 is connected to the support base 301 through a scissor lifting mechanism. The movement of the scissor lifting mechanism is driven by a cylinder 310. The front and rear parts of the support base 301 are respectively provided with a limit block 312. The limit block 312 is screwed with a limit screw 311. The limit screw 311 is a hard limit for the downward movement of the auxiliary support. 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 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 upward 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.

[0039] The lifting plate 309 is equipped with a horizontally arranged rebar support roller 308 and a vertically arranged rebar front limit post 306 and rebar rear limit post 307 that match the rebar support roller 308. The opening space between the rebar front limit post 306 and the rebar rear limit 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 opening formed by the rebar front limit post 306 and the rebar rear limit post 307, the opening of the pneumatic clamp 610, and the opening of the mold 609 are in the same position to restrict the forward and backward movement of the rebar.

[0040] The lifting plate 309 is also provided with a material dropping guide 313 and a material removal component A314 that can swing in the vertical plane. The material removal component A314 is used to lift the steel bars on the material support frame 608 onto the material dropping guide 313 and to remove the processed steel bars from the mold 609. The material dropping guide 313 is used to make the steel bars fall into the opening formed by the front limit post 306 and the rear limit post 307 of the steel bars, and at the same time make the steel bars fall into the opening of the mold 609.

[0041] like Figure 9As shown, the material removal component A314 is a single piece, comprising a hook portion A3143, a rod portion A3142, and a pry arm 3141 connected sequentially from front to back. The pry arm 3141 is connected to the rod portion A3142 in an L-shape, and a hinge hole 3144 is provided at the connection between the pry arm 3141 and the rod portion A3142. The material removal component A314 is hinged to the lifting plate 309 through the hinge hole 3144 and the hinge pin II 318. The protruding end of the rod portion A3142 is connected to the hinge pin I 317. The piston rod B of cylinder B316 is hinged, and the cylinder body B of cylinder B316 is hinged to hinge lug 315, which is welded to lifting plate 309; hook A3143 is adapted to the position of material guide 313, and rod A3142 is adapted to the position of the opening formed by reinforcing bar front limiting post 306 and reinforcing bar rear limiting post 307; hook A3143 includes a horizontal surface 31431, an inclined surface 31432 and a vertical surface 31433 in sequence from front to back.

[0042] Both the movable bending machine 6 and the fixed bending machine 2 are hinged with a material-lifting component B611, which can swing in the vertical plane. For example... Figure 10 As shown, the material-receiving component B611 is an integral part, including a hook portion B6112 and a rod portion B6111 connected sequentially from front to back. The tail end of the rod portion B6111 is provided with a hole K6113. The hook portion B6112 and the hook portion A3143 have the same shape and are adapted to each other. The rod portion B6111 and the rod portion A3142 are adapted to each other. The material-receiving component B611 is fixedly connected to the rotating shaft 612 through the hole K6113. The rotating shaft 612 is rotatably connected to the movable bracket 601. One end of the connecting rod 613 is fixedly connected to the rotating shaft 612. The other end of the connecting rod 613 is hinged to the piston rod C of the cylinder C614. The cylinder body C of the cylinder C614 is hinged to the movable bracket 601.

[0043] like Figure 6 and Figure 11As shown, the equal-pitch 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 sequentially and coaxially fixedly mounted on the mounting shaft 508. The two large sprockets 505 are driven by chain A504, the two medium sprockets 506 are driven by chain B503, and the two small sprockets 507 are driven by chain C502. (The last sentence appears to be incomplete and possibly refers to a different mechanism.) A connecting frame 604 is fixedly connected to the rear of the movable support 601 of the machine 6. The connecting frame 604 is fixedly connected to the chain A504, the auxiliary support A4 is fixedly connected to the chain B503, and the auxiliary support B3 is fixedly connected to the chain C502. Driven by the motor 606, the movable bending machine 6 moves closer to or further away from the fixed bending machine 2, thereby 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 speed ratio of the movable bending machine 6, the auxiliary support A4, and the auxiliary support B3 moving in the same direction is 3:2:1.

[0044] The working principle is as follows:

[0045] When the support frame 608 of the movable bending machine 6 and the fixed bending machine 2 receives the steel bar pushed by the automatic feeding unit, the control cylinder B316 is activated, causing the material removal component A314 to swing upward (the cylinder C614 can also be activated simultaneously, causing the material removal component B611 to swing upward). The horizontal plane 31431 of the hook part A3143 of the material removal component A314 lifts the steel bar to be processed and raises it above the dropping guide 313. As the material removal component A314 swings, the steel bar slides down along the inclined plane 31432 of the hook part A3143 to the vertical plane 31433. The control cylinder B316 reverses its movement, causing the material take-off part A314 to swing downwards and return to its initial state (if the aforementioned material take-up part B611 swings upwards, the control cylinder C614 needs to reverse its movement to cause the material take-up part B611 to swing downwards and return to its original position). At this time, the steel bar falls on the material drop guide 313 and falls along the slope on the material drop guide 313 into the opening space between the front limit post 306 and the rear limit post 307 of the steel bar (and also falls into the opening of the pneumatic clamp 610 and the opening of the mold 609), and finally falls on the steel bar support roller 308, so that the pneumatic clamp 610 clamps the steel bar. After the bending process is completed, the pneumatic clamp 610 is first released from the grip of the steel bar, and then the cylinder B316 is controlled to move, causing the stripper A314 to swing upward. The rod A3142 of the stripper A314 pushes the processed steel bar out of the mold 609. After the steel bar slides onto the storage rack, the cylinder B316 is controlled to move in the opposite direction, causing the stripper A314 to swing downward to return to the initial state.

[0046] Adjust the position of the movable bending machine 6 according to the length of the steel bar to be processed. Due to the setting of the equal-spacing variable-pitch mechanism, the two auxiliary supports are respectively supported at the three equal division points of the steel bar.

[0047] If the length of the reinforcing bar to be processed is relatively short, and with the two auxiliary supports at their normal lifting height, the shortest processing length of both the movable bending machine 6 and the fixed bending machine 2 may exceed the length of the reinforcing bar to be processed. In this case, if... Figures 12-14 As shown, first lower the two auxiliary supports to their lower limits, then adjust the position of the movable bending machine 6 to make it closer to the fixed bending machine 2 to meet the bending processing of shorter steel bars. At this time, the two auxiliary supports can be accommodated in the corresponding accommodating spaces ASⅠ and ASⅡ respectively, but the automatic feeding function will no longer be activated.

[0048] In the description of this utility model, terms such as "inner", "outer", "upper", "lower", "front", and "rear" that indicate orientation or positional relationship are used only for the convenience of describing this utility model, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
