[0013] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0014] Please see Figures 1 to 4This application provides an automatic feeding and thread rolling device for galvanized tie rods, including a frame 1 and a thread rolling mechanism. The thread rolling mechanism includes a receiving frame for transport by a transfer frame 10, an electric cylinder for pushing the tie rod to move on the receiving frame, a limiting block for stabilizing and limiting the sliding of the tie rod, and a thread rolling machine, etc. A guide table 2 is fixedly installed on the frame 1. Three sets of inclined grooves 3 are symmetrically arranged on the frame 1, with two inclined grooves 3 in each set. The two inclined grooves 3 in each set are symmetrically arranged, and a limiting frame 4 is slidably engaged within the inclined groove 3. The two limiting frames 4 are symmetrically arranged. A bidirectional... The threaded rod 5 and the two limit frames 4 are threadedly connected to the bidirectional threaded rod 5. A pressure cylinder 6 is fixedly installed on the frame 1. The pressure cylinder 6 is T-shaped, with only the pressure blocks 7 at both ends and the lifting block 8 at the bottom in a sealed sliding connection. The pressure source inside the pressure cylinder 6 is pneumatic or hydraulic. The pressure blocks 7 are slidably and sealedly connected to both ends of the pressure cylinder 6. The limit frame 4 is connected to the pressure blocks 7. The lifting block 8 is slidably and sealedly connected to the bottom of the pressure cylinder 6. The insert plate 9 with a limit pull rod is slidably installed on the frame 1. The lifting block 8 is connected to the insert plate 9. The transfer frame 10 is rotatably installed on the frame 1.
[0015] In this embodiment, the pull rod is placed on the guide table 2 and gradually rolls between the two limiting frames 4. It can be rotated by driving the bidirectional threaded rod 5 to adjust the distance between the two limiting frames 4, so that only one row of pull rods can be accommodated between the two limiting frames 4. When the distance between the two limiting frames 4 is adjusted, the pressure blocks 7 that are sealed and sliding at both ends of the pressure cylinder 6 can move together. As the two pressure blocks 7 move in opposite directions, when the pressure inside the pressure cylinder 6 changes, the lifting block 8 connected to the insert plate 9 at the bottom of the pressure cylinder 6 can be pressed and raised or lowered, thereby driving the insert plate 9 to rise or fall. The distance that the lifting block 8 can move when the pressure inside the pressure cylinder 6 changes can be controlled by adjusting the size of the lifting block 8, so that the insert plate 9 can always be accurately inserted between the two pull rods. When the bottom of the row of pull rods between the two limit frames 4 falls onto the transfer frame 10, the insert plate 9 can extend to separate the pull rod on the transfer frame 10 from the next pull rod. Then, the transfer frame 10 can drive the pull rod on it to rotate and transport it to the receiving frame in the thread rolling mechanism to support the pull rod. Then the pull rod is pushed to perform automatic thread rolling.
[0016] In some embodiments, to protect the pull rod, several guide plates 11 are hinged to the guide platform 2, and a limiting groove 12 is provided on the limiting frame 4 near the guide platform 2. The fixed shaft rotatably mounted at the bottom of the guide plate 11 is slidably engaged in the limiting groove 12. Thus, when the limiting frame 10 descends a large distance, the pull rod can still roll down along the guide plate 11 onto the limiting frame 4, thereby avoiding instability of the device and wear of the pull rod caused by direct impact. The setting of the limiting groove 12 allows the guide plate 11 to maintain a relatively stable tilt state and will not vibrate with the rolling of the pull rod. The setting of several guide plates 11 makes it easy for pull rods of different lengths to be automatically fed and threaded, and the pull rod is not easy to get stuck in the limiting groove 12 or the hinge end of the guide plate 11. If the pull rod is always long and has a large diameter, only one guide plate 11 needs to be installed.
[0017] In some embodiments, to facilitate the adjustment of the distance between the two limiting frames 4, a mating frame 13 is slidably engaged on the frame 1, and a bidirectional threaded rod 5 is rotatably mounted on the mating frame 13. A mating rod 14 is rotatably mounted on the mating frame 13 on the opposite side of the bidirectional threaded rod 5, and both limiting frames 4 are slidably connected to the mating rod 14. By mounting the bidirectional threaded rod 5 on the mating frame 13, the bidirectional threaded rod 5 can rise and fall with the limiting frame 4, and the frame 1 can also limit the bidirectional threaded rod 5. The mating rod 14 allows the end of the limiting frame 4 without the bidirectional threaded rod 5 to slide stably. To reduce the overall weight of the limiting frame 4 and avoid excessive thread wear on the threads of the bidirectional threaded rod 5, and to facilitate the control of the bidirectional threaded rod 5 as it rises and falls, it can be manually driven to rotate. Since the limiting frame 4 does not require frequent adjustment, manual adjustment also helps to reduce costs.
[0018] In some embodiments, to facilitate the connection between the limiting frame 4 and the pressure block 7, a pressure groove 15 is provided on the pressure block 7, and the limiting frame 4 is slidably engaged in the pressure groove 15. Thus, the limiting frame 4 can slide up and down in the pressure groove 15 to accommodate the lifting and lowering of the limiting frame 4.
[0019] In some embodiments, to facilitate the connection between the lifting block 8 and the insert plate 9, the insert plate 9 is fixedly installed on the mounting frame 16. The mounting frame 16 has mounting grooves 17 on both sides. A V-shaped frame 18 is fixedly installed on the lifting block 8, and the V-shaped frame 18 is slidably engaged in the mounting groove 17. Thus, when the insert plate 9 and the mounting bracket 16 move, the V-shaped bracket 18 can maintain its connection with the mounting bracket 16 and the insert plate 9 by sliding within the mounting groove 17; the bottom of the V-shaped bracket 18 is rotatably mounted with a support shaft, which slides and engages within the mounting groove 17, thereby reducing friction; since only one row of tie rods can be accommodated between the two limiting brackets 4, the number of tie rods in this row can be reduced by decreasing the height of the limiting brackets 4, and the impact of the mechanism's own weight on the lifting block 8 can be reduced by using lightweight and rigid materials to make the insert plate 9, the mounting bracket 16, and the V-shaped bracket 18; the purpose of having a slot for inserting the insert plate 9 on only one side of the limiting bracket 4 is to avoid having a slot on the other side as well, so that when the insert plate 9 is inserted, it is squeezed out of the slot on the other side; and the insert plate 9 has a chamfer for easy insertion, which pushes the tie rods upward and separates them, avoiding the disadvantage that the material is easy to stack and jam when separated on the inclined surface of the guide table 2.
[0020] In some embodiments, to facilitate the pushing of the insert plate 9, a linear actuator 19 is fixedly mounted on the frame 1. The linear actuator 19 can be a multi-stage electric cylinder, and a push block 20 is fixedly mounted on the output end of the linear actuator 19. The push block 20 is slidably engaged with the mounting frame 16. Through the slidable engagement between the push block 20 and the mounting frame 16, the raising and lowering of the mounting frame 16 and the insert plate 9 will not affect the linear actuator 19 driving the push block 20 to push. The linear actuator 19 can be connected to the electric cylinder, thread rolling drive motor, and other mechanisms in the thread rolling mechanism through an external signal processor.
[0021] In some embodiments, to facilitate the transport of the pull rods on the transfer frame 10, a short plate 21 and a long plate 22 are fixedly installed on the transfer frame 10, with the long plate 22 located on the side closer to the thread rolling mechanism. The transfer frame 10 can move a small distance towards the guide table 2 from the center position of the two limiting frames 4, and can also deflect to a certain extent towards the long plate 22. Thus, pull rods with smaller diameters can be directly limited and transported by the short plate 21 and the long plate 22, while the center of gravity of pull rods with larger diameters can be located on the long plate 22, preventing them from rolling directly after falling. The short plate 21 and the long plate 22 can be coordinated with the changes in the spacing of the limiting frames 4. The short plate 21 is shorter and will not collide with the limiting frames 4 even when they are close together. The long plate 22 has a certain offset angle, so that when the limiting frames 4 approach each other and descend, they can be located on the same side of the long plate 22 without colliding. The transfer frame 10 can be driven by a customized low-speed servo motor with a gearbox for accurate deflection, and the servo motor can be connected to an external signal processor.
[0022] The fixed connection and rotating installation in the above embodiments can all be achieved by welding, screw fasteners and other forms in the prior art, and the rotating installation can be achieved by bearings, circular rotating blocks and circular grooves. All of the above components are standard parts, and those that are not standard parts can also be specially customized, so the inventor will not elaborate further.
[0023] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

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 all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
