Description

Technical Field

[0001] This utility model belongs to the technical field of feeding devices, and in particular to a feeding device for a thread rolling machine. Background Technology

[0002] Thread rolling machines are multi-functional cold extrusion forming machine tools. They can perform thread rolling, straightening, diameter reduction, burnishing, and various forming rolling processes on workpieces in a cold state within their rolling pressure range. However, most of them now require manual feeding of steel bars into the thread rolling machine for processing, which can easily lead to danger when personnel manually add steel bars. This operation is not only cumbersome, but also affects the physical and mental safety of personnel.

[0003] A Chinese patent (authorization announcement number CN209632040U) discloses a thread rolling machine, which "includes a processing table, a protective cover, and a thread rolling device. The protective cover is disposed on the top of the processing table, and the thread rolling device is located inside the protective cover. The bottom of the top plate of the protective cover is also provided with a cleaning and cooling mechanism, which includes a cooling box disposed on one side of the processing table."

[0004] It is evident that the cited patent document presents a risk of danger when personnel manually add reinforcing bars. Utility Model Content

[0005] The purpose of this invention is to provide a feeding device for a thread rolling machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for a thread rolling machine, comprising a thread rolling base, a feeding box for holding steel bars to be processed by the thread rolling machine is installed on the top surface of the thread rolling base, a hollow groove is provided on the inner bottom surface of the thread rolling base, a threaded shaft is rotatably connected to the inner side wall of the hollow groove via a pin, a moving block is threadedly sleeved on the periphery of the threaded shaft, an inclined L-shaped push block is connected to the top surface of the moving block, a through groove for the push block to pass through is opened on the inner top surface of the hollow groove, a limiting plate is welded to the inner side wall of the through groove, the push block is slidably sleeved on the periphery of the limiting plate, an entry groove for the push block to pass through is opened on one side of the feeding box, and a discharge groove for the steel bars to pass through and enter the thread rolling machine for processing is opened on the other side of the feeding box.

[0007] Preferably, the inner cavity of the feeding box is symmetrically provided with two baffles for restricting the reinforcing bars, and connecting blocks are welded to the opposite sides of the two baffles.

[0008] Preferably, the free ends of both connecting blocks extend to the outside of the feeding box and are connected to a vertical plate, and two fixing posts are symmetrically welded to both sides of the feeding box.

[0009] Preferably, the free ends of each pair of fixed columns are connected to a fixed plate, and the two vertical plates are slidably sleeved on the periphery of the two fixed columns.

[0010] Preferably, one side of each of the two fixed plates is rotatably connected to a bidirectional threaded rod via a pin, and both vertical plates are threaded onto the periphery of the bidirectional threaded rod.

[0011] Preferably, a mounting plate for connecting and fixing to an external thread rolling machine is fixedly installed on one side of the thread rolling base.

[0012] Preferably, two slide rails are symmetrically provided on one side of the feeding box, and baffles for limiting the discharge groove are slidably provided on the periphery of the two slide rails.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This thread rolling machine feeding device, by turning on the drive motor, provides power for the rotation of the thread shaft, which in turn drives the push block to move, thereby pushing the steel bars that need to be processed by the thread rolling machine to move through the discharge groove and move to the external thread rolling machine for processing. Compared with the existing device for rolling steel bars, this device can push the steel bars into the thread rolling machine in a regular manner, avoiding the need for manual insertion of steel bars into the thread rolling machine and reducing the danger that may occur when personnel manually add steel bars.

[0015] By rotating the bidirectional threaded rod, power can be provided to move the two vertical plates, thereby enabling the two baffles to move laterally, restricting the reinforcing bars and ensuring that the reinforcing bars are stacked vertically in the feeding box, avoiding the accumulation of reinforcing bars, and thus facilitating the sequential movement of the reinforcing bars into the external thread rolling machine for processing.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] like Figures 1 to 5The feeding device for a thread rolling machine shown includes a thread rolling base 1. A feeding box 2 for holding the reinforcing bars to be processed by the thread rolling machine is installed on the top surface of the thread rolling base 1. A slot 3 is provided on the inner bottom surface of the thread rolling base 1. A threaded shaft 4 is rotatably connected to the inner side wall of the slot 3 via a pin. A drive motor is installed on one side of the thread rolling base 1. The output end of the drive motor passes through the thread rolling base 1 and is fixedly connected to one end of the threaded shaft 4. A movable block 5 is threaded around the periphery of the threaded shaft 4. An inclined L-shaped push block 6 is connected to the top surface of the movable block 5. A through slot 7 is opened on the inner top surface of the slot 3 for the push block 6 to pass through. One side of the feeding box 2 is... The feeding box 2 has an inlet groove 9 through which the pusher block 6 passes, and a discharge groove 10 on the other side for the rebar to pass through and enter the thread rolling machine for processing. The rebar that needs to be processed by the thread rolling machine is added into the feeding box 2. At this time, the drive motor is turned on, which drives the threaded shaft 4 to rotate, thereby driving the moving block 5 to move. The moving block 5 can drive the pusher block 6 to move in the cavity of the through groove 7. When the pusher block 6 moves, it will pass through the inlet groove 9 into the feeding box 2 and push the rebar at the bottom. After being pushed, the rebar at the bottom will be discharged from the discharge groove 10 and can be moved to the external thread rolling machine for processing.

[0028] After the bottommost rebar is removed, the second rebar will press against the top surface of push block 6. At this time, the drive motor is turned on in reverse, which will drive push block 6 to move in the opposite direction. When push block 6 exits from the inlet slot 9, the rebar will move downward due to gravity. At this time, the drive motor will drive push block 6 to move again, which will push the second rebar. By repeating the operation, the thread rolling can be fed, avoiding the need for manual insertion of rebar into the thread rolling machine and reducing the impact on personnel's physical and mental safety.

[0029] A limiting plate 8 is welded to the inner wall of the through groove 7. The push block 6 is slidably sleeved on the periphery of the limiting plate 8. When the push block 6 moves, it will move on the periphery of the limiting plate 8, which restricts the movement trajectory of the push block 6 and the moving block 5. The top surface of the limiting plate 8 is at the same level as the top surface of the thread rolling base 1, so as to prevent the bottom steel bar from getting stuck inside the through groove 7.

[0030] The inner cavity of the feeding box 2 is symmetrically provided with two baffles 11 for restricting the reinforcing bars. The upper half of one of the baffles 11 is arc-shaped, which makes it easier to place the reinforcing bars between the two baffles 11.

[0031] Two connecting blocks 12 are welded to opposite sides of the two baffles 11. The free ends of the two connecting blocks 12 extend to the outside of the feeding box 2 and are connected to vertical plates 13. Two fixed posts 14 are symmetrically welded to both sides of the feeding box 2. The free ends of each pair of fixed posts 14 are connected to a fixed plate 15. The two vertical plates 13 are slidably sleeved around the two fixed posts 14. The opposite sides of the two fixed plates 15 are rotatably connected to a bidirectional threaded rod 16 via a pin. One end of the bidirectional threaded rod 16 passes through one of the fixed plates 15 and is connected to a handle. The two vertical plates 13 are threaded around the bidirectional threaded rod 16. By rotating the handle according to the diameter of the reinforcing bar, the bidirectional threaded rod 16 can be rotated, so that the two vertical plates 13 can drive the two connecting blocks 12 to move respectively. This allows the two baffles 11 to move in opposite directions, so that the distance between the two baffles 11 is only enough for one reinforcing bar to pass through. This allows the reinforcing bars between the two baffles 11 to be stacked longitudinally rather than piled up, which facilitates the subsequent sequential feeding of reinforcing bars.

[0032] When the two vertical plates 13 move the connecting block 12 and the baffle 11, they will move around the two fixed columns 14 respectively, which can restrict the movement trajectory of the baffle 11, the connecting block 12 and the vertical plate 13.

[0033] A mounting plate 17 for connecting and fixing to an external thread rolling machine is fixedly installed on one side of the thread rolling base 1.

[0034] Two slide rails 18 are symmetrically arranged on one side of the feeding box 2. A baffle plate 19 for restricting the discharge groove 10 is slidably arranged on the periphery of the two slide rails 18. The baffle plate 19 can be moved according to the diameter of the steel bar to restrict the discharge groove 10, so that only one steel bar can pass through the exposed space of the discharge groove 10. The baffle plate 19 is fixed to the feeding box 2 by bolts and screw holes, which makes it easy to adjust the position of the baffle plate 19.

[0035] Working principle:

[0036] The feeding device for this thread rolling machine adds the reinforcing bars to be processed into the feeding box 2. The bottom reinforcing bar abuts against the thread rolling base 1. At this time, the drive motor is turned on, which drives the threaded shaft 4 to rotate, thereby moving the moving block 5. The moving block 5 can then move the push block 6. When the push block 6 moves, it passes through the inlet groove 9 into the feeding box 2 and pushes the bottom reinforcing bar. The bottom reinforcing bar is pushed and discharged from the outlet groove 10, and can then be moved into the external thread rolling machine for processing. At this time, the drive motor drives the threaded shaft 4 to rotate in the opposite direction, which drives the push block 6 to move in the opposite direction. When the push block 6 exits from the inlet groove 9, the longitudinally stacked reinforcing bars in the feeding box 2 will move downwards due to gravity. At this time, the drive motor drives the push block 6 to move again, allowing the push block 6 to push the second reinforcing bar. By repeating the operation, the thread rolling can be fed, avoiding the need for manual insertion of reinforcing bars into the thread rolling machine and reducing the impact on personnel safety.
