Description

Technical Field

[0001] This utility model relates to the field of steel cage production equipment, and in particular to a longitudinal steel bar preparation device. Background Technology

[0002] During the welding of reinforcing cages, the longitudinal reinforcing bars are typically moved in a step-by-step manner, with the transverse reinforcing bars continuously welded onto the longitudinal reinforcing bars. Currently, the longitudinal reinforcing bars are mainly straightened and cut using an integrated reinforcing bar straightening and shearing machine. After shearing, the reinforcing bars usually fall off and accumulate, requiring workers to sort and move them one by one, resulting in high workload for workers and low material preparation efficiency. Utility Model Content

[0003] To address the problems of high labor intensity and low material feeding efficiency in the existing technology of longitudinal steel bar welding due to reliance on manual material preparation, this utility model provides a longitudinal steel bar material preparation device.

[0004] The technical solution adopted in this utility model is:

[0005] A longitudinal steel bar preparation device includes a steel bar pushing mechanism, which includes a steel bar pushing component and a displacement structure. The steel bar pushing component is located on the side of the steel bar shearing mechanism of the integrated steel bar straightening and shearing machine facing the discharge end and is used to receive the sheared steel bars. The displacement structure is connected to the steel bar pushing component to drive the steel bar pushing component to push the received steel bars towards the discharge end.

[0006] Preferably, the initial position of the rebar pusher is located between the initial position of the rebar shearing mechanism and the position where the rebar shearing mechanism cuts the rebar.

[0007] Preferably, the displacement structure includes a transmission mechanism, a slide rail, and an elastic element. The transmission mechanism is arranged along the rebar discharge direction. The rebar pusher is slidably connected to the slide rail via a slider one. One end of the elastic element is slidably connected to the slide rail via a slider two. The slider two is connected to the transmission mechanism. The other end of the elastic element is connected to the rebar pusher. The slider one is located on the side of the slider two facing the discharge end.

[0008] Preferably, the transmission mechanism includes a motor, a sprocket, and a chain. The chain is arranged along the direction of rebar discharge. The chain is connected to at least one sprocket. At least one sprocket is coaxially connected to the output shaft of the motor. The second slider is connected to the chain.

[0009] Preferably, the motor is connected to an encoder.

[0010] Preferably, the elastic element is a spring, one end of which is connected to the second slider, and the other end is connected to the steel bar pusher.

[0011] Preferably, the reinforcing bar pusher is grooved, and the groove of the reinforcing bar pusher has an upwardly protruding reinforcing bar abutment.

[0012] Preferably, the side of the reinforcing bar abutment facing the discharge end has a reinforcing bar limiting part that is recessed towards the feed end.

[0013] Preferably, the side of the steel bar pusher facing the discharge end is provided with a steel bar receiving groove.

[0014] Preferably, the rebar receiving trough is connected to a lifting mechanism.

[0015] The beneficial effects of this utility model are:

[0016] By using a rebar pushing mechanism in conjunction with an existing rebar straightening and shearing integrated machine, the rebar straightening and shearing integrated machine straightens and then shears the rebar. The sheared rebar falls onto the rebar pushing component, and the displacement structure pushes the sheared rebar away, which can be sent into the silo for buffering. Compared with letting the sheared rebar fall and pile up messily and then relying on manual sorting and handling, this greatly reduces labor intensity and improves material preparation efficiency.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0023] During the welding of reinforcing cages, the longitudinal reinforcing bars are generally long, and are typically moved in a step-by-step manner to continuously weld the transverse reinforcing bars onto them. When preparing the longitudinal reinforcing bars, a reinforcing bar straightening and shearing machine is usually used to straighten and shear the raw materials. However, due to the lack of a corresponding receiving and pushing mechanism, the sheared reinforcing bars often fall and pile up haphazardly, requiring manual sorting and handling. This results in high labor intensity for workers and low material preparation efficiency.

[0024] To address the aforementioned problems of high labor intensity and low material preparation efficiency, such as Figure 1 and Figure 2 As shown, this embodiment provides a longitudinal steel bar preparation device, including a steel bar pushing mechanism 3. The steel bar pushing mechanism 3 includes a steel bar pushing component 4 and a displacement structure 5. The steel bar pushing component 4 is located on the side of the steel bar cutting mechanism 2 of the steel bar straightening and cutting integrated machine 1 facing the discharge end and is used to receive the steel bars cut. The displacement structure 5 is connected to the steel bar pushing component 4 to drive the steel bar pushing component 4 to push the received steel bars towards the discharge end.

[0025] Among them, the steel bar straightening and shearing integrated machine 1 is an existing device. The improvement of this embodiment is that a steel bar pushing mechanism 3 is added to cooperate with it. It can receive the steel bars cut by the steel bar shearing mechanism 2 and push them to the material hopper for welding. The welding device can take the material from the hopper through the material picking device. Compared with letting the cut steel bars fall and pile up messily and then relying on manual sorting and handling, the labor intensity is greatly reduced and the material preparation efficiency is improved.

[0026] When the rebar shearing mechanism 2 shears the rebar, the contact between the shearing part and the rebar creates a clamping effect. Therefore, the conveying of the rebar causes the rebar shearing mechanism 2 to move from its initial position towards the discharge end until the rebar is cut (at this point, the rebar shearing mechanism 2 is in the position where the rebar is cut, also known as the shearing position). Driven by a spring, the rebar shearing mechanism 2 returns to its initial position. Generally, due to the inertia of the conveyed rebar, the cut rebar will move a certain distance towards the discharge end and fall into the rebar pusher 4. However, to ensure that the reinforcing bar falls into the reinforcing bar pusher 4, in one embodiment, the initial position of the reinforcing bar pusher 4 is located between the initial position of the reinforcing bar shearing mechanism 2 and the position where the reinforcing bar shearing mechanism 2 cuts the reinforcing bar. In this way, when the reinforcing bar shearing mechanism 2 moves towards the discharge end, it will contact the reinforcing bar pusher 4 and push the reinforcing bar pusher 4 to move towards the discharge end together, so that the reinforcing bar pusher 4 is close to the reinforcing bar shearing mechanism 2 when the reinforcing bar is cut. In fact, the reinforcing bar pusher 4 can be set to be as close as possible to the reinforcing bar shearing mechanism 2 in the initial position, so that the reinforcing bar pusher 4 can be pushed to move together as soon as the reinforcing bar shearing mechanism 2 starts to move. In this way, even if the position of the reinforcing bar shearing mechanism 2 fluctuates slightly each time the reinforcing bar is cut, it can be guaranteed that the reinforcing bar shearing mechanism 2 and the reinforcing bar pusher 4 are close together at the position where the reinforcing bar is cut.

[0027] To further ensure that the cut rebar falls stably into the rebar pusher 4 and to achieve the resetting of the rebar pusher 4 so that it can continue to work stably, in one embodiment, such as Figure 3 As shown, the displacement structure 5 includes a transmission mechanism 6, a slide rail 7, and an elastic element 8. The transmission mechanism 6 is arranged along the rebar discharge direction. The rebar pusher 4 is slidably connected to the slide rail 7 via a slider 1 9. One end of the elastic element 8 is slidably connected to the slide rail 7 via a slider 2 10. The slider 2 10 is connected to the transmission mechanism 6. The other end of the elastic element 8 is directly connected to the rebar pusher 4, or indirectly connected to the rebar pusher 4 via a slider 1 9. The slider 1 9 is located on the side of the slider 2 10 facing the discharge end.

[0028] When the rebar shearing mechanism 2 shears the rebar, the transmission mechanism is not activated, and the elastic element 8 remains in place. The rebar shearing mechanism 2, driven by the rebar, pushes the rebar pusher 4 to overcome the resistance of the elastic element 8 and move towards the discharge end. When the rebar is cut, the rebar shearing mechanism 2 resets, and the rebar pusher 4 loses the thrust of the rebar shearing mechanism 2. Under the force of the elastic element 8, the rebar pusher 4 moves towards the feed end to reset. The cut rebar does not move towards the feed end under gravity, so the rebar pusher 4 moves to the end of the cut rebar facing the feed end. Then, the transmission mechanism 6 is activated, driving the slider 10 to push the slider 9, thereby moving the rebar pusher 4 towards the discharge end, pushing the cut rebar towards the discharge end and allowing it to enter the hopper for buffering. After the transmission mechanism 6 drives the rebar pusher 3 to move to the preset stroke, the transmission mechanism 6 is activated to move in the opposite direction, driving the elastic element 8 to pull the rebar pusher 4 towards the feed end to complete the reset. The slide rail 7 is slidably connected to the steel bar pusher 4 and the elastic member 8 through slider 1 9 and slider 2 10, guiding the smooth movement of the steel bar pusher 4 and the elastic member 8. Slider 2 10 and chain 12 can be connected by a connecting block or directly. Limiting blocks can be set at both ends of the slide rail 7 to prevent slider 1 9 and slider 2 10 from disengaging.

[0029] The transmission mechanism 6 can be implemented in various ways, such as in the form of a belt and pulley or a linear module, etc. In one embodiment, such as Figure 3 As shown, the transmission mechanism 6 includes a motor 11, a sprocket 13, and a chain 12. The chain 12 is arranged along the direction of rebar discharge. The chain 12 is connected to at least one sprocket 13, such as one end connected to the sprocket 13 and the other end connected to the sprocket 13, a pulley, or a sliding plate. At least one sprocket 13 is coaxially connected to the output shaft of the motor 11. The sliding block 10 is connected to the chain 12. Compared with belts and linear modules, the chain 12 has a better load-bearing capacity; therefore, the chain 12 is preferred.

[0030] To make the stroke of slider 2 10 controllable, in one embodiment, motor 11 can be a servo motor, or motor 11 can be connected to an encoder to control the stroke of slider 2 10, that is, to control the stroke of the rebar pusher 4 when pushing the rebar.

[0031] To achieve the elastic connection between slider 2 10 and slider 1 9 and to drive slider 1 9 to reset, elastic element 8 can be implemented by selecting components such as gas spring. However, considering cost and service life, in one embodiment, elastic element 8 is preferably a spring. One end of the spring is connected to slider 10, and the other end is connected to the steel bar pusher 4, or connected to slider 1 9 to indirectly achieve the connection with the steel bar pusher 4.

[0032] To ensure the stable and continuous operation of the rebar pusher chute, in one embodiment, such as Figure 4 As shown, the rebar pusher 4 is grooved, and the groove of the rebar pusher 4 has an upwardly protruding rebar abutment part 14. The grooved rebar pusher 4 facilitates lateral positioning of the cut rebar, and the upwardly protruding rebar abutment part 14 facilitates pushing the cut rebar. The rebar abutment part 14 can be integrally formed directly in the groove, or it can be a separately set plate-like part.

[0033] During the process of pushing the reinforcing bar by the reinforcing bar pusher 4, in order to prevent the end of the reinforcing bar from disengaging from the reinforcing bar abutment part 14, in one embodiment, such as Figure 4 As shown, the rebar abutment portion 14 has a rebar limiting portion 15 recessed towards the feeding end on the side facing the discharge end. The recessed rebar limiting portion 15 prevents the rebar from detaching from the rebar abutment portion 14 in the vertical direction. The recess can be formed by the rebar limiting portion 15 bending towards the feeding end itself, or a baffle extending towards the discharge end can be provided at the top of the rebar abutment portion 14 to form the recessed area.

[0034] To better guide the sheared steel bars into the silo buffer, the sheared steel bars are supported and positioned. In one embodiment, such as... Figure 1 and Figure 2 As shown, the steel bar pusher 4 is provided with a steel bar receiving groove 16 on the side facing the discharge end. When the steel bar is being transported, it falls onto the steel bar receiving groove 16 after passing through the steel bar shearing mechanism 2 and the steel bar pusher 4. The steel bar receiving groove 16 is aligned with the feed inlet of the silo and guides the steel bar into the silo buffer.

[0035] Since longitudinal reinforcing bars are generally quite long, usually longer than the reinforcing bar receiving groove 16, it is necessary to guide the end facing the discharge end into the hopper before the reinforcing bar is cut. To prevent the reinforcing bar pusher 4 from colliding with the reinforcing bar receiving groove 16 during movement, a lifting mechanism 17 can be connected to the reinforcing bar receiving groove 16. Specifically, the lifting mechanism 17 can be located at the bottom of the reinforcing bar receiving groove 16. When the reinforcing bar pusher 4 approaches the reinforcing bar receiving groove 16, the lifting mechanism 17 lowers the reinforcing bar receiving groove 16 a certain distance to avoid the reinforcing bar pusher 4. After the reinforcing bar pusher 4 returns to its original position, the reinforcing bar receiving groove 16 is raised again. The lifting mechanism 17 can be implemented using a pneumatic cylinder, a hydraulic cylinder, or a linear module, etc. Considering load factors, a hydraulic cylinder is preferred.

[0036] In this utility model, the hopper can be a section of pipe for conveying longitudinal steel bars. One end of the pipe is connected to the steel bar receiving groove 16 to facilitate the entry of cut steel bars. The other end can be equipped with a clamp driven by a moving mechanism (such as a linear module or chain) to clamp the steel bars and pull them out for welding.

[0037] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
