Description

Technical Field

[0001] This invention relates to the field of metal products technology, and in particular to an automatic positioning device for rolling steel sleeve equipment and its usage method. Background Technology

[0002] Rolled steel sleeves are a type of wire rope rigging commonly used in large-scale spatial architectural structures as tension cables. The manufacturing process generally involves threading a wire rope or steel strand through the inner hole of the sleeve, then pulling the sleeve on a machine. On either side of the sleeve are a pair of annular molds. The friction between the sleeve and the molds drives the molds to rotate, thus deforming the sleeve through rolling (cold) extrusion and tightly connecting it to the wire rope (or steel strand). The rotation of the molds is synchronized by a pair of meshing gears. During the extrusion process, because a certain gap exists between the molds, the excess material formed during extrusion creates regular edges on both sides of the sleeve.

[0003] In the rolling steel sleeve equipment, the mold is installed on a pair of meshing gears. The gears rotate freely. During operation, the end of the steel sleeve needs to be aligned with the mold before it can be extruded. It is more suitable for single-piece multi-variety steel sleeve rigging. However, large-scale spatial building structures often require mass production of the same specifications or automated production. Therefore, it is essential to improve the equipment, reduce auxiliary time, and improve production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic positioning device for rolling steel sleeve equipment and its usage method, so as to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following solution: The present invention provides an automatic positioning device for a rolling steel sleeve equipment, including a frame, a drive mechanism at one end of the frame, a base fixedly connected to the end of the frame away from the drive mechanism, two first gears symmetrically mounted on the base, a mold on the outer side of the first gears, a rack meshing between the two first gears, an elastic connecting mechanism on the rack, a traction head at the top of the elastic connecting mechanism, the traction head fixedly connected to the drive mechanism, a part to be processed on the traction head, the part to be processed being located between the two molds, and a sensor switch at the end of the rack away from the drive mechanism.

[0006] Preferably, the elastic connection mechanism includes a first groove disposed on the top surface of the rack, a first spring fixedly connected in the first groove, a connecting seat fixedly connected to the end of the first spring away from the drive mechanism, and the top of the connecting seat extending to the outside of the first groove and fixedly connected to the traction head.

[0007] Preferably, the end of the traction head away from the first groove is provided with a second groove, and the part to be processed is provided in the second groove.

[0008] Preferably, the base is provided with a first protective plate, which is located on the outside of the mold, and the base is provided with a second protective plate on the side close to the mold.

[0010] Preferably, the drive mechanism includes a hydraulic cylinder fixedly connected to the frame, a connecting plate fixedly connected to one end of the hydraulic cylinder away from the frame, a pull rod fixedly connected to one end of the connecting plate, and the other end of the pull rod fixedly connected to the traction head.

[0011] Preferably, the part to be processed is a steel sleeve.

[0012] Preferably, a sensor switch bracket is fixedly connected to the side of the base near the second protective plate, and the sensor switch is provided on the sensor switch bracket.

[0013] Preferably, a method of using an automatic positioning device for a rolling steel sleeve equipment includes the following steps:

[0014] 1) Install the steel sleeve and use an induction switch for sensing;

[0016] 3) Reset the device. After the steel sleeve is squeezed, remove the steel sleeve and reset the drive mechanism and rack.

[0017] This invention discloses the following technical effects: An external robotic arm places the workpiece into the traction head. Upon sensing the workpiece, a sensor switch activates the drive mechanism, which moves the traction head to the left. The workpiece is then pressed by two molds, and friction causes the molds to rotate. Each mold drives a first gear, which in turn drives a meshing rack to move, ensuring synchronization of the two mold movements and thus guaranteeing product quality. This invention has a simple structure and is easy to use. It enables automatic installation of the steel sleeve using a robotic arm, or simplifies manual operation, reduces auxiliary time, and improves work efficiency. By using the rack as a carrier, the meshing rotation of the molds and the displacement of the steel sleeve are organically combined, achieving automatic positioning of the molds during the traction process, further realizing automation.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figure 1-4 This invention provides an automatic positioning device for a rolling steel sleeve equipment, including a frame 1. One end of the frame 1 is provided with a drive mechanism. The end of the frame 1 away from the drive mechanism is fixedly connected to a base 2. Two first gears 3 are symmetrically installed on the base 2. A mold 4 is provided on the outer side of the first gears 3. A rack 5 meshes between the two first gears 3. An elastic connecting mechanism is provided on the rack 5. A traction head 6 is provided on the top of the elastic connecting mechanism. The traction head 6 is fixedly connected to the drive mechanism. A part to be processed 7 is provided on the traction head 6. The part to be processed 7 is located between the two molds 4. An inductive switch 8 is provided at the end of the rack 5 away from the drive mechanism.

[0027] The part to be processed is placed in the traction head 6 by an external robotic arm. After the induction switch 8 senses the part to be processed 7, the drive mechanism starts to work. The drive mechanism drives the traction head 6 to move to the left. The part to be processed 7 is squeezed by two molds 4. The friction force drives the molds 4 to rotate. The two molds 4 drive the first gear 3 to rotate respectively. The two first gears 3 drive the racks 5 that mesh with them to move, so as to ensure the synchronization of the movement of the two molds 4, thereby ensuring product quality.

[0028] Further optimization of the scheme: the elastic connection mechanism includes a first groove 9 set on the top surface of the rack 5, a first spring 10 fixedly connected in the first groove 9, a connecting seat 11 fixedly connected to the end of the first spring 10 away from the drive mechanism, and the top of the connecting seat 11 extends to the outside of the first groove 9 and is fixedly connected to the traction head 6.

[0029] As the workpiece 7 is moved, the traction head 6 simultaneously acts on the rack 5 via the first spring 10. Because the rack 5 moves at a different speed than the traction head 6, the first spring 10 is compressed (or stretched, depending on the pitch circle of the gear and the diameter of the mold circle). Once the workpiece 7, i.e., the steel sleeve, is pulled to the required size, the extrusion process is complete. The steel sleeve is then removed, the drive mechanism returns, and the traction head 6 pushes the rack 5 back to its original position.

[0030] At the beginning of the movement of the traction head 6, the first spring 10 of the elastic connection mechanism is pre-tightened. Its pre-tightening force can directly drive the rack 5 to move, and at the same time drive the mold 4 to accurately press against the set position of the workpiece 7 to be processed. When the mold 4 contacts the workpiece 7 to be processed, due to the difference between the rotation radius of the mold 4 and the rotation radius of the first gear 3, if the rotation radius of the mold 4 is greater than the pitch circle radius of the first gear 3, the first spring 10 is placed at the front end of the rack 5, and the first gear 3 rotates under the friction force of the mold 4. The moving speed of the rack 5 will be less than the moving speed of the workpiece 7 to be processed, and the first spring 10 will be gradually compressed during the movement. If the rotation radius of the mold 4 is less than the pitch circle radius of the first gear 3, the moving speed of the rack 5 will be higher than that of the workpiece 7 to be processed, and the first spring 10 needs to be placed at the rear end of the rack 5.

[0031] The design is further optimized by providing a second groove 12 at the end of the traction head 6 away from the first groove 9, and a part 7 to be processed is provided in the second groove 12.

[0032] To further optimize the design, a first protective plate 13 is provided on the base 2, which is located on the outside of the mold 4. A second protective plate 14 is provided on the side of the base 2 closest to the mold 4, which further improves the production efficiency of the equipment.

[0033] To further optimize the design, a third groove 15 is provided on the outer side of the mold 4 away from the first gear 3. The third groove 15 is adapted to the part 7 to be processed and is used to extrude the steel sleeve.

[0034] The scheme is further optimized. The drive mechanism includes a hydraulic cylinder 16 fixedly connected to the frame 1. A connecting plate 17 is fixedly connected to one end of the hydraulic cylinder 16 away from the frame 1. One end of the connecting plate 17 is fixedly connected to one end of the pull rod 18. The other end of the pull rod 18 is fixedly connected to the traction head 6.

[0035] Hydraulic cylinder 16 is activated, pushing connecting plate 17 to the left. Connecting plate 17 drives pull rod 18 to the left, and pull rod 18 drives traction head 6 to the left.

[0036] The plan was further optimized. Part 7 to be processed is a steel sleeve, which is hollow and contains a steel wire rope in the middle.

[0037] In a further optimized design, a sensor switch bracket 19 is fixedly attached to the side of the base 2 near the second protective plate 14, and a sensor switch 8 is provided on the sensor switch bracket 19.

[0038] A method for using an automatic positioning device for a rolling mill steel sleeve equipment includes the following steps:

[0039] 1) Install the steel sleeve and sense it through the induction switch 8;

[0040] 2) Squeeze the steel sleeve, start the drive mechanism, and make the drive mechanism drive the traction head 6 to move;

[0041] 3) Reset the device. After the steel sleeve is squeezed, remove the steel sleeve and reset the drive mechanism and rack 5.

[0042] The workpiece to be processed is placed in the traction head 6 by an external robotic arm. After the induction switch 8 senses the workpiece 7, the hydraulic cylinder 16 is activated. The hydraulic cylinder 16 pushes the connecting plate 17 to move to the left. The connecting plate 17 drives the pull rod 18 to move to the left, and the pull rod 18 drives the traction head 6 to move to the left. The steel sleeve is squeezed by the two molds 4. The friction drives the molds 4 to rotate. The molds 4 are respectively mounted on the two first gears 3. The rotation of the first gears 3 drives the rack 5 to move, ensuring the synchronous operation of the two molds 4. While the traction head 6 drives the steel sleeve to move, the first spring 10 acts on the rack 5 from below. Since the moving speed of the rack 5 is different from that of the traction head 6, the first spring 10 is compressed (or stretched, depending on the pitch circle of the gear and the diameter of the mold circle). When the steel sleeve is pulled to the desired size, the extrusion process is completed. The steel sleeve is removed, the hydraulic cylinder 16 returns, causing the pull rod 18 to move to the right, and the traction head 6 pushes the rack 5 to reset.
