Description

Technical Field

[0001] This utility model relates to the field of U-shaped hanging ring processing technology, and in particular to a U-shaped hanging ring forming tool. Background Technology

[0002] U-shaped couplings are metal connectors widely used in power, construction, and machinery industries. Their core function is to achieve a reliable connection through pin holes or threads at both ends. In cranes and conveyors, U-shaped couplings, as static connectors, must be used differently from shackles: shackles allow for frequent disassembly, while couplings are suitable for long-term fixed applications. In overhead transmission lines, U-shaped couplings are used to connect insulator strings to tower crossarms, or to fix conductors to tension clamps.

[0003] In the existing technology, when bending and forming a U-shaped hanging ring, the material needs to be heated first and then placed into the tooling. Then the bending device bends the material. However, if the operator does not align the material when placing it and then uses a clamping device to clamp the material, the two through holes of the U-shaped hanging ring may not be aligned after bending, which will affect the quality of the processing. Utility Model Content

[0004] This utility model mainly provides a U-shaped hanging ring forming fixture that facilitates improved placement accuracy and prevents misalignment of the two through holes of the U-shaped hanging ring.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a U-shaped hanging ring forming fixture, comprising: a frame, four evenly distributed support rods fixedly installed on the top of the frame, a top plate fixedly installed on the top of the four support rods, a fixing plate fixedly installed on the top of the top plate, a through hole through the outer wall of the fixing plate, a limiting groove formed on the outer wall of the fixing plate, an electromagnet fixedly installed on the inner wall of the limiting groove, a spring fixedly installed on the outer wall of the electromagnet, a moving plate fixedly installed at one end of the spring, a positioning plate fixedly installed on the outer wall of the moving plate, a cylinder fixedly installed on the top of the frame, the output end of the cylinder penetrating the top plate and fixedly installed with a lifting plate, an opening through the top of the lifting plate, a placement platform and a limiting block fixedly installed on the top of the lifting plate, a first hydraulic cylinder and a second hydraulic cylinder symmetrically installed on the top of the top plate, mounting plates fixedly installed at the output ends of the first hydraulic cylinder and the second hydraulic cylinder, and punches provided on the outside of the mounting plates.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Please see Figures 1-5 This utility model provides a technical solution: a U-shaped hanging ring forming fixture, comprising: a frame 1, four evenly distributed support rods 2 fixedly installed on the top of the frame 1, a top plate 3 fixedly installed on the top of the four support rods 2, a fixing plate 17 fixedly installed on the top of the top plate 3, a through hole 18 through the outer wall of the fixing plate 17, a limiting groove 19 formed on the outer wall of the fixing plate 17, an electromagnet 20 fixedly installed on the inner wall of the limiting groove 19, a spring 21 fixedly installed on the outer wall of the electromagnet 20, and a movable plate fixedly installed at one end of the spring 21. 22. A positioning plate 23 is fixedly installed on the outer wall of the movable plate 22. A cylinder 12 is fixedly installed on the top of the frame 1. The output end of the cylinder 12 passes through the top plate 3 and is fixedly installed on the lifting plate 13. An opening 14 is opened through the top of the lifting plate 13. A placement platform 15 and a limiting block 16 are fixedly installed on the top of the lifting plate 13. A first hydraulic cylinder 9 and a second hydraulic cylinder 10 are symmetrically installed on the top of the top plate 3. An installation plate 11 is fixedly installed on the output end of the first hydraulic cylinder 9 and the second hydraulic cylinder 10. A punch 32 is provided on the outside of the installation plate 11.

[0019] like Figure 5As shown, the outer wall of the mounting plate 11 has a slot 24, the top surface of the slot 24 has a storage groove 25, a locking block 26 is slidably installed inside the storage groove 25, the top of the locking block 26 has a threaded groove 27, the threaded groove 27 is threadedly connected to a threaded rod 28, the top of the threaded rod 28 passes through the mounting plate 11 and is fixedly installed with a handle 29. When the operator rotates the handle 29, the handle 29 drives the threaded rod 28 to rotate, and the locking block 26 moves along the storage groove 25.

[0020] like Figure 5 As shown, a plate 30 is fixedly installed on the outer wall of the punch 32. A slot 31 is provided on the top of the plate 30. When the locking block 26 enters the slot 31, the plate 30 can be fixed.

[0021] like Figure 1 As shown, a motor 4 is fixedly installed at the bottom of the frame 1. The output end of the motor 4 passes through the frame 1 and is fixedly installed on a turntable 5. A connecting rod 6 is fixedly installed on the top of the turntable 5. A guide wheel 7 is set on the top of the connecting rod 6. When bending, the worker starts the motor 4. The output end of the motor 4 drives the turntable 5 to rotate. The inner wall of the guide wheel 7 contacts the outer wall of the material. The guide wheel 7 rotates along the U-shaped opening 8 and pushes the material to bend.

[0022] like Figure 1 As shown, a U-shaped opening 8 is provided at the top of the top plate 3 to facilitate the passage of the connecting rod 6.

[0023] like Figure 4 As shown, the outer wall of the movable plate 22 fits against the inner wall of the limiting groove 19 to prevent the movable plate 22 from tilting.

[0024] like Figure 5 As shown, the outer wall of the insert plate 30 fits against the inner wall of the slot 24, and the inner wall of the slot 31 fits against the outer wall of the block 26. When the insert plate 30 enters the slot 24 and the block 26 enters the slot 31, the insert plate 30 can be fixed in place and will not shake.

[0025] The usage and working principle of this device are as follows: During clamping, the operator places the material on the top of the placement platform 15. One end of the material moves to the side of the through hole 18, and the outer wall of the material contacts the outer wall of the limiting block 16. When one end of the material is in contact with the outer wall of the positioning plate 23, the material hole coincides with the through hole 18. Finally, the operator activates the first hydraulic cylinder 9. The output end of the first hydraulic cylinder 9 pushes the punch 32 into the through hole 18. The punch 32 squeezes the material to fix it, thus improving the placement accuracy. When the bending is finished, the operator activates the electromagnet 20. The iron moving plate 22 is attracted and moves along the inside of the limiting groove 19. The positioning plate 23 enters the limiting groove 19. At this time, the operator can activate the cylinder 12. The output end of the cylinder 12 pushes the lifting plate 13 to rise. At this time, the lifting plate 13 can drive the U-shaped hanging ring away from the outside of the fixed plate 17 for easy material removal. During bending, the operator starts motor 4, which drives turntable 5 to rotate. The inner wall of guide wheel 7 contacts the outer wall of the material, and guide wheel 7 rotates along the U-shaped opening 8, pushing the material to bend. When the material is bent 180 degrees, the other hole in the material moves to the other side of through hole 18. The operator then starts the second hydraulic cylinder 10, and punch 32 enters the other hole in the material to correct the U-shaped round hole. When punch 32 wears out, the operator rotates handle 29, which drives threaded rod 28 to rotate. The locking block 26 leaves the slot 31, allowing the operator to pull out insert plate 30 and replace the new punch 32. When inserting insert plate 30 into slot 24, the operator rotates handle 29 in the opposite direction, and locking block 26 descends along storage groove 25 and enters slot 31. This completes the replacement process and improves replacement efficiency.
