Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a ring bending device for a metal spiral wound gasket ring. Background Art

[0002] Spiral wound gaskets are widely used sealing gaskets and offer the best resilience among semi-metallic gaskets. They are made by alternating, overlapping, and spirally winding high-quality metal strips (usually in a "V" or "W" shape) such as SUS304 or SUS316 with other soft materials such as graphite, asbestos, polytetrafluoroethylene, and non-asbestos. Their structural density can be customized to meet varying locking force requirements, and their maximum compression is controlled by inner and outer steel rings, making them adaptable to various temperature and pressure conditions.

[0003] During the preparation of metal spiral wound gaskets, some soft materials need to be bent and wound around their surface. However, there are some shortcomings in the ring bending process: First, the soft material is continuously wound, causing the outer diameter of the entire ring to continue to expand. The staff needs to constantly use a vernier caliper to measure the size back and forth, which seriously affects the efficiency of the ring bending. After the soft material is wound, it needs to be welded at its end to prevent it from loosening. The welding also requires manual welding, but manual welding has problems such as uneven welding and inaccurate point control. Utility Model Content

[0022] In this embodiment, as the soft material is continuously wound, the size of the entire ring will continue to increase and then contact the pulley 6, and the pulley 6 will be controlled to approach the side plate 3. The distance to the calibration plate 8 is monitored in real time by the photoelectric sensor 9, so that the outer diameter of the ring can be accurately grasped, thereby quickly and effectively ensuring that the size of the ring meets the standard.

[0023] Example 2, refer to Figure 1 A ring bending device for a metal wound gasket ring, a top plate 10 is welded to the top outer wall of the top frame 2, and the top outer wall of the top plate 10 is fixedly connected to a cylinder 11 by screws, and the piston rod of the cylinder 11 is fixedly connected to a laser welding head 12.

[0024] In this embodiment, as the cylinder 11 pushes the laser welding head 12 downward, and with the cooperation of the electric rotary chuck 13 driving the ring to rotate, the laser welding head 12 can evenly weld the ends of the soft material, accurately grasp the position of the welding point, and ensure the uniformity of the welding.

[0027] Reference Figure 1 and Figure 3 The inner wall of the top of the base frame 1 is fixedly connected to a cylinder 2 15 , and the piston rod of the cylinder 2 15 is fixedly connected to a mounting frame 2 16 . The inner wall of the mounting frame 2 16 is rotatably connected to a positioning wheel 17 , and the positioning wheel 17 is arranged at the bottom of the base 14 .

[0030] Working principle: First, place the ring on the outer ring of the holder 14, and drive the holder 14 to rotate through the electric rotating chuck 13 to control the rotation of the ring. At the same time, the positioning wheel 17 is pushed to the bottom of the ring by the cylinder 2 15, and then the staff wraps the soft material around the ring along the positioning wheel 17 and the ring. As the soft material is continuously wound, the size of the entire ring will continue to increase and then contact the pulley 6, and control the pulley 6 to approach the side plate 3. The distance to the calibration plate 8 is monitored in real time by the photoelectric sensor 9 to accurately grasp the outer diameter of the ring. Once the size is determined, the soft material can be cut off. As the cylinder 11 pushes the laser welding head 12 downward, and with the cooperation of the electric rotating chuck 13 to drive the ring to rotate, the laser welding head 12 can evenly weld the ends of the soft material, so that the soft material is tightly wrapped around the outside of the ring.
