Description

Technical Field

[0001] This utility model relates to the field of rebar straightening machine technology, specifically a cutting structure for a rebar straightening machine. Background Technology

[0002] In a rebar straightening production line, the straightened and length-set bars need to be instantly cut by a high-speed rotating flying shear or crank-connecting rod cutting mechanism. Since modern high-speed straightening machines typically operate at speeds of 80–150 m / min⁻¹, the cut rebar, after leaving the clamping rollers, is still horizontally thrown along the roller conveyor at a linear velocity of 3–6 m / s⁻¹. According to the energy formula E=½mv², taking a Φ20 mm, 12 m long HRB400 rebar as an example, its mass is approximately 30 kg, and its impact kinetic energy can reach 135–540 J. When high-speed rebar collides directly with a rigid collection frame or already stacked rebar, it causes indentations and bending deformation at the ends and surfaces of the rebar, reducing the quality of subsequent thread rolling or tapping. Utility Model Content

[0003] The purpose of this invention is to provide a cutting structure for a rebar straightening machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cutting structure for a rebar straightening machine, comprising a machine housing, a rebar straightening machine mounted on the top of the machine housing, a conveying roller mounted on the side of the rebar straightening machine, a cylinder mounted on the front of the rebar straightening machine, a cutting blade connected to the output end of the cylinder, a storage box placed on one side of the machine housing, a speed reduction box located below the conveying roller on the upper part of the storage box, a drop plate mounted on the top of the speed reduction box, a movable groove formed in the inner wall of the speed reduction box, a speed reduction plate movably fitted into the inner cavity of the movable groove, a spring mounted at the bottom of the speed reduction plate, and one end of the spring connected to the inner wall of the speed reduction box.

[0005] As a further improvement of this utility model, the front and rear toilets on the top of the speed reduction box are provided with symmetrically distributed drop plates, and the drop plates are inclined.

[0006] As a further improvement of this utility model, the inner cavity of the speed reduction box is provided with movable grooves, speed reduction plates and springs on both the front and rear sides, and the two sets of movable grooves, speed reduction plates and springs are distributed vertically.

[0007] As a further improvement of this utility model, the speed reduction plate is connected to the speed reduction box by several springs, and the speed reduction plate is inclined.

[0008] As a further improvement of this utility model, a support plate is installed on one side of the top of the storage box, a motor is installed on the front side of the support plate, a lead screw is connected to the output end of the motor, a guide rod is installed on the rear side of the support plate, a moving block is sleeved on the outer side of the lead screw and the guide rod, the moving block is threadedly connected to the lead screw, and one side of the moving block is connected to one side of the speed reduction box.

[0009] As a further improvement of this utility model, the lead screw is provided with guide rods on both the upper and lower sides, and the guide rods are provided with support plates on both the front and rear sides.

[0010] Compared with the prior art, the beneficial effects of this utility model are: The cutting structure of this rebar straightening machine has a speed reduction box, a drop plate, a movable groove, and a spring above the storage box. After the rebar is cut, it falls onto the drop plate and rolls into the speed reduction box. The speed reduction plate and spring slow down the cut rebar, preventing it from colliding too much when it falls and causing deformation.

[0011] The cutting structure used in the rebar straightening machine is driven by a motor to rotate the lead screw. Since the lead screw is threadedly connected to the moving block, it drives the moving block and the speed reduction box to move along the outside of the guide rod. This makes it easy to adjust the position of the speed reduction box above the storage box, and to change the position of the rebar so that the rebar can be arranged and placed in the inner cavity of the storage box.

[0016] Please see Figures 1-4 This utility model provides a cutting structure for a rebar straightening machine, including a machine housing 1. A rebar straightening machine 3 is installed on the top of the machine housing 1. A conveying roller 4 is installed on the side of the rebar straightening machine 3. A cylinder 5 is installed on the front side of the rebar straightening machine 3. A cutting blade 6 is connected to the output end of the cylinder 5. A storage box 2 is placed on one side of the machine housing 1. A speed reduction box 7 located below the conveying roller 4 is provided on the upper part of the storage box 2. A drop plate 8 is installed on the top of the speed reduction box 7. A movable groove 9 is opened on the inner wall of the speed reduction box 7. A speed reduction plate 10 is movably sleeved in the inner cavity of the movable groove 9. A spring 11 is installed at the bottom of the speed reduction plate 10. One end of the spring 11 is connected to the inner wall of the speed reduction box 7. The storage box 2 is equipped with a deceleration box 7, a drop plate 8, a movable groove 9, a deceleration plate 10, and a spring 11. After the steel bar is cut, it falls onto the drop plate 8 and rolls into the deceleration box 7. The deceleration plate 10 and the spring 11 slow down the cut steel bar, preventing it from having a large impact when it falls and causing deformation.

[0017] As a further improvement of this utility model, the front and rear ends of the top of the deceleration box 7 are provided with symmetrically distributed drop plates 8, which are inclined. By utilizing the shape characteristics of the drop plates 8, the range of steel bars that the deceleration box 7 can accept is increased.

[0018] As a further improvement of this utility model, the inner cavity of the deceleration box 7 is provided with movable grooves 9, deceleration plates 10, and springs 11 on both the front and rear sides, and the two sets of movable grooves 9, deceleration plates 10, and springs 11 are distributed vertically. By setting two sets of movable grooves 9, deceleration plates 10, and springs 11, the steel bars can be decelerated more effectively, and the impact force can be mitigated.

[0019] As a further improvement of this utility model, the speed reduction plate 10 is connected to the speed reduction box 7 by a number of springs 11, and the speed reduction plate 10 is inclined.

[0020] As a further improvement of this utility model, a support plate 16 is installed on one side of the top of the storage box 2. A motor 12 is installed on the front side of the support plate 16, and a lead screw 13 is connected to the output end of the motor 12. A guide rod 15 is installed on the rear side of the support plate 16. A moving block 14 is sleeved on the outer side of the lead screw 13 and the guide rod 15. The moving block 14 is threadedly connected to the lead screw 13, and one side of the moving block 14 is connected to one side of the speed reduction box 7. The motor 12 drives the lead screw 13 to rotate. Since the lead screw 13 is threadedly connected to the moving block 14, the moving block 14 and the speed reduction box 7 move along the outer side of the guide rod 15. This facilitates adjusting the position of the speed reduction box 7 above the storage box 2, making it easier to change the position of the dropped steel bars, so that the steel bars can be arranged and placed in the inner cavity of the storage box 2.

[0021] As a further improvement of this utility model, guide rods 15 are provided on both the upper and lower sides of the lead screw 13, and support plates 16 are provided on both the front and rear sides of the guide rods 15.

[0022] Working principle: When using this device, the conveying roller 4 and the rebar straightening machine 3 are connected to an external drive. The rebar is conveyed through the rebar straightening machine 3 and straightened. After the rebar passes through the conveying roller 4 for a certain length, the conveying of the rebar stops. The cylinder 5 is connected to the outside and is used as a drive to move the cutting blade 6 downward to cut the rebar. The cut rebar is conveyed through the conveying roller 4, moves out of the conveying roller 4, and falls onto the drop plate 8. Under the influence of gravity, it rolls into the deceleration box 7 and contacts the deceleration plate 10 and spring 11 inside the deceleration box 7 to decelerate. Then the rebar falls into the collection box 2 for collection.
