The discharge member is rotatably connected to the bottom of the first mounting member. The discharge drive assembly is located on the first mounting member and connected to the discharge member to drive the discharge member to rotate up and down.

[0006] As a further improvement to the above technical solution: the discharge drive assembly includes a swing arm, one end of which is hinged to the first mounting component and the other end is connected to the discharge component.

[0008] As a further improvement to the above technical solution: the frame is provided with a swing limiting member, the swing limiting member is provided with a swing limiting groove, and the swing arm passes through the swing limiting groove.

[0009] As a further improvement to the above technical solution: the first mounting component or the discharge component is provided with a second mounting component, and the sliding drive component is provided on the second mounting component.

[0015] Compared with the prior art, the advantages of the present invention are as follows:

[0016] The rebar straightening device disclosed in this invention involves a rebar straightening mechanism followed by a shearing mechanism. When the rebar head contacts the stop, it pushes the discharge mechanism and shearing mechanism to move together until the rebar head reaches the designed position. The discharge drive assembly drives the discharge component to rotate downwards, forming a ramp structure. The shearing mechanism cuts the rebar, and the cut rebar falls onto the discharge component. The stop, driven by the sliding drive component, actively slides and separates from the rebar head, releasing the constraint on the length direction of the rebar. This allows the rebar to roll smoothly off the discharge component, resulting in smooth discharge, reduced accumulation, no need for manual cleaning, and greater convenience of use.

[0017] Other features and advantages of the present invention will be described in detail in the following detailed description section. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Figures 1 to 6 This invention illustrates an embodiment of the rebar straightening device. The rebar straightening device of this embodiment includes a frame 1, a straightening mechanism 2 disposed on the frame 1, and a shearing mechanism 3 slidably disposed on the frame 1. It also includes a discharge mechanism 4 disposed on the side of the shearing mechanism 3 away from the straightening mechanism 2. Figure 1 The discharge mechanism 4 is located to the right of the shearing mechanism 3. The discharge mechanism 4 includes a first mounting member 41, a stop member 42, a discharge member 43, a discharge drive assembly 44, and a sliding drive member 46 for driving the stop member 42. The first mounting member 41 is connected to the shearing mechanism 3. The sliding direction of the stop member 42 is the same as the sliding direction of the shearing mechanism 3. The discharge member 43 is rotatably connected to the bottom of the first mounting member 41. The discharge drive assembly 44 is located on the first mounting member 41 and connected to the discharge member 43 to drive the discharge member 43 to rotate up and down. Preferably, the first mounting member 41 is an L-shaped plate, and the discharge member 43 is also a plate. The first mounting member 41 and the discharge member 43 cooperate to form a U-shaped structure with the opening facing forward (i.e., towards the operator), facilitating the movement of the reinforcing bar 5 inside. The stop member 42 can be a stop block, baffle, etc. The sliding drive member 46 can be, for example, a cylinder, hydraulic cylinder, etc. The specific structure of the straightening mechanism 2 can be the same as in the prior art and will not be described in detail here.

[0031] In this embodiment of the rebar straightening equipment, the rebar 5 is straightened by the straightening mechanism 2 and then by the shearing mechanism 3. When the head end ( Figure 1 When the right end of the steel bar 5 contacts the stop 42, it pushes the discharge mechanism 4 and the shearing mechanism 3 to move to the right as a whole until the end of the steel bar 5 moves to the designed position. See details. Figure 6 The discharge drive assembly 44 drives the discharge component 43 to rotate downward to form a ramp structure. The shearing mechanism 3 cuts the steel bar 5, and the cut steel bar 5 falls onto the discharge component 43. The retaining component 42 slides actively under the drive of the sliding drive component 46 to separate from the end of the steel bar 5, releasing the constraint on the length direction of the steel bar 5, so that the steel bar 5 can roll smoothly off the discharge component 43. The discharge is smooth, the accumulation is reduced, no manual cleaning is required, and the use is more convenient.

[0032] See details Figure 5 In this embodiment, the discharge drive assembly 44 includes a swing arm 441. One end of the swing arm 441 is hinged to the first mounting member 41, and the other end is connected to the discharge member 43. The swing arm 441 is provided with a stepped guide groove 443, and the frame 1 is provided with a guide member 11 that cooperates with the guide groove 443 (preferably, the guide member 11 is a guide roller or rolling bearing, which can reduce the frictional resistance and wear with the guide groove 443) to drive the swing arm 441 to swing up and down. When the swing arm 441 moves to the right under the push of the steel bar 5, the guide member 11 cooperates with the stepped guide groove 443, causing the swing arm 441 to swing upward. The swing arm 441 then drives the discharge member 43 to rotate downward, making it easier for the cut steel bar 5 to roll off the discharge member 43. The swinging action of the swing arm 441 and the rotation action of the discharge member 43 are realized by the movement of the steel bar 5. No additional drive components are required, which simplifies the structure, improves the reliability of the equipment, and reduces the equipment cost. The structure is reasonable and effective.

[0033] See details Figure 4 In this embodiment, the discharge component 43 is mounted on the L-shaped first connecting rod 431, which is hinged to the first mounting component 41. The other end of the swing arm 441 is hinged to the second connecting rod 442. The discharge component 43 is also provided with a third connecting rod 444, which is hinged to the second connecting rod 442. When the swing arm 441 swings upward, it drives the second connecting rod 442 and the third connecting rod 444 to move upward, thereby causing the discharge component 43 and the first connecting rod 431 to rotate counterclockwise. The discharge component 43 forms a ramp structure, which is reasonable and effective. Preferably, the length of the second connecting rod 442 is adjustable, which facilitates the adjustment of the rotation angle of the discharge component 43.

[0034] See details Figure 3 In this embodiment, the frame 1 is provided with a swing limiting member 12 (such as a limiting plate, a limiting block, etc.), and the swing limiting member 12 is provided with a swing limiting groove 121, through which the swing arm 441 passes. The swing limiting groove 121 can limit the maximum upward swing angle of the swing arm 441, and at the same time prevent the swing arm 441 from moving forward, causing the guide member 11 to disengage from the guide groove 443, thereby further improving the reliability of the equipment.

[0035] See details Figure 5In this embodiment, the first mounting member 41 is provided with a second mounting member 45 (e.g., mounting plate, mounting block, etc.), the sliding drive member 46 is provided on the second mounting member 45, and the stop member 42 is provided on the sliding drive member 46. When the reinforcing bar 5 moves to the right, the sliding drive member 46 does not move, and the reinforcing bar 5 pushes the stop member 42, the first mounting member 41, etc., to move to the right as a whole; when the reinforcing bar 5 is cut, the sliding drive member 46 drives the stop member 42 to move to the right (the first mounting member 41 does not move), so that the stop member 42 slides and actively separates from the end of the reinforcing bar 5, releasing the constraint in the length direction of the reinforcing bar 5. The structure is simple and reliable. Of course, in other embodiments, the second mounting member 45 can also be provided on the discharge member 43.

[0036] Furthermore, in this embodiment, the installation position of the second mounting member 45 is adjustable from that of the first mounting member 41, and the adjustment direction is the same as the sliding direction of the stop member 42. Preferably, the second mounting member 45 can be tightened onto the first mounting member 41 using bolts, screws, etc., which allows for easy adjustment of the installation position of the second mounting member 45 to accommodate steel bars 5 of different lengths.

[0037] Furthermore, in this embodiment, the discharge component 43 is a discharge plate, one side of which is rotatably connected to the first mounting component 41, and the opposite side is provided with a downwardly inclined portion 432. Compared to a flat plate, providing an inclined portion 432 on the discharge plate can further facilitate the downward rolling of the reinforcing bar 5, resulting in a simple and effective structure.

[0038] See details Figure 2 In this embodiment, the shearing mechanism 3 includes a third mounting member 31, a moving blade 32, a moving blade drive member 33 (e.g., a cylinder, hydraulic cylinder, etc.), and an annular stationary blade 34. The stationary blade 34 and the moving blade drive member 33 are mounted on the third mounting member 31, and the moving blade 32 is mounted on the moving blade drive member 33 (e.g., a hydraulic cylinder, etc.). The straightened reinforcing bar 5 passes through the annular stationary blade 34, which can position the reinforcing bar 5 and prevent it from moving. Then, the moving blade drive member 33 drives the moving blade 32 to move, which can effectively cut the reinforcing bar 5. The structure is simple and reliable.

[0039] See details Figure 5 In this embodiment, the first mounting member 41 and the retaining member 42 are provided with blocking members 47 (such as blocking plates, blocking rods, etc.), which are distributed on opposite sides of the reinforcing bar 32. When the moving blade 32 cuts the reinforcing bar 5, the blocking member 47 can prevent the reinforcing bar 5 from flying forward and injuring the operator, further improving the safety of the equipment. Of course, in other embodiments, the blocking member 47 may only be provided on the first mounting member 41 or the retaining member 42.

[0040] See details Figure 2In this embodiment, the frame 1 is provided with an elastic element 13 for driving the shearing mechanism 3 to reset (preferably, the elastic element 13 is a helical spring, but in other embodiments it can also be an elastic rope, etc.). After the shearing and discharge of the steel bar 5 are completed, the elastic element 13 drives the shearing mechanism 3 and the discharge mechanism 4 to move to the left to reset, further improving the automation level of the equipment. The structure is simple and reliable.

[0041] Furthermore, the frame 1 is equipped with a position detection element 14 (e.g., a position sensor or limit switch) for detecting the position of the shearing mechanism 3. During normal operation, the shearing mechanism 3 is pushed to the right by the reinforcing bar 5 until the reinforcing bar 5 is cut and successfully discharged from the discharge port 43. The distance the shearing mechanism 3 moves to the right is relatively fixed or within the design range. When the reinforcing bar 5 is not cut in time or cannot be discharged from the discharge port 43, the distance the shearing mechanism 3 moves to the right will increase. If this is not detected, the shearing mechanism 3 will be pushed to its limit position and unable to move further to the right, causing the reinforcing bar 5 to bend. If not handled promptly, this may cause equipment damage or other serious consequences. By using the position detection element 14 to detect the position of the shearing mechanism 3, when misoperation or equipment malfunction causes misalignment of the shearing mechanism 3, timely handling can be carried out to prevent the aforementioned problems.

[0042] The working principle of the rebar straightening device of this invention is as follows:

[0043] After the steel bar 5 is passed through the straightening mechanism 2 and the shearing mechanism 3, the equipment is started. The straightening mechanism 2 rotates to straighten the steel bar 5 inside and continuously feed it to the right.

[0044] When the reinforcing bar 5 moves to the right to the discharge mechanism 4, the right end of the reinforcing bar 5 will press against the baffle 42 and drive the discharge mechanism 4 and the shearing mechanism 3 to move to the right as a whole.

[0045] When the arm moves to the designated position, the relative position of the swing arm 441 and the guide member 11 mounted on the frame 1 changes, causing the right end of the swing arm 441 to swing upward. This, along with the second link 442, the third link 444, and the first link 431, causes the discharge member 43 to rotate downward, facilitating the sheared steel bar 5 to fall off. Simultaneously, the moving blade drive member 33 drives the moving blade 32 to extend and shear the steel bar 5. At this time, the moving blade 32 temporarily acts as a material stopper, preventing the shearing mechanism 3 and the discharge mechanism 4 from being pulled back to their initial positions by the elastic member 13. Since the discharge member 43 has now rotated to form a ramp, when the steel bar 5 falls onto the discharge member 43, it will roll down the ramp.

[0046] After shearing is completed, the moving blade drive 33 drives the moving blade 32 to retract, and the shearing mechanism 3 and the discharge mechanism 4 are pulled back to the leftmost position by the elastic force of the elastic element 13, thus returning to the initial state, waiting for the right end of the steel bar 5 to press against the stop element 42 again, thus starting the next cycle.

[0047] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
