Description

Technical Field

[0001] The present application relates to the technical field of sealing machines, and in particular to a high-frequency heating spinning sealing machine. Background Art

[0002] The metal pipe fittings are first extended at one end by the feeding mechanism and rotated at high speed, heated and softened by the high-frequency coil, and then the spinning mechanism is used to press the roller against the red-hot end of the round tube to squeeze it and seal it. Since the surface after sealing is relatively rough, it needs to be polished.

[0003] In this regard, China's patent application number is CN202022033600.1, which discloses a high-frequency spinning sealing device for metal tubes. This solution mainly uses a cylinder to push out the file to grind the sealing end after sealing, thereby improving processing efficiency.

[0004] However, in the process of implementing the technical solution in the embodiments of the present application, the inventor of the present application found that the above technology has at least the following technical problems:

[0005] 1. The grinding process is carried out independently after sealing, which takes up the sealing time and affects the processing efficiency;

[0006] 2. The contact position between the file and the round tube is relatively fixed. This position is severely worn and requires frequent maintenance, which affects processing efficiency. Utility Model Content

[0010] In a specific embodiment, the spinning mechanism further includes a screw and a motor, the screw is rotatably connected to the rotating seat, the screw is threadedly connected to the slide, and the output end of the motor is connected to the screw shaft.

[0011] In the above implementation process, the motor drives the screw to rotate, and then drives the slide to move linearly along the rotating seat, and cooperates with the rotation of the rotating seat itself to spin-seal the round tube.

[0012] In a specific implementation, the damping element includes a damping bearing and a friction plate, the damping bearing is mounted on the slide, the friction plate is mounted on the damping bearing, and the roller end face is movably fitted with the friction plate.

[0013] In the above implementation process, after the friction plate is bonded to the end face of the roller, the damping bearing is used to make the linear speed of the roller slower than the linear speed of the round tube, resulting in relative sliding, so that the friction surface on the roller grinds against the round tube and continuously changes the bonding area, which is beneficial to cooling the friction surface, reducing wear and improving the durability of the friction surface.

[0014] In a specific embodiment, the pushing member includes a rotating shaft, the roller is detachably connected to the rotating shaft, and the rotating shaft is movably connected to the slide.

[0017] In a specific embodiment, the friction surface is circular and movably inserted into the outer circle of the roller.

[0018] In the above implementation process, the rotating shaft and the roller, as well as the friction surface and the roller are all splined. When the friction surface needs to be replaced, the rotating shaft is pulled out from the roller, and then the circular friction surface is removed from the roller for replacement. In this embodiment, the rotating shaft and the roller, as well as the friction surface and the roller, have a small amount of interference, which can ensure that they do not loosen during circumferential movement.

[0019] In a specific embodiment, the friction surface and the smooth surface have the same radius.

[0020] In the above implementation process, the friction surface and the smooth surface have the same radius, so that the smooth surface can be directly moved circumferentially to switch to the friction surface after spinning to improve efficiency.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0029] See also Figure 1-Figure 4 The present application provides a high-frequency heating spinning sealing machine, including a machine platform 10, on which a round tube feeding mechanism 20, a spinning mechanism 30 and a high-frequency heating mechanism 40 are arranged, and the spinning mechanism 30 includes a roller 31, and the roller 31 is axially divided into a smooth surface 32 and a friction surface 33, and the end surface of the roller 31 is movably connected with a damping member 50, and a pusher 60 is arranged on the roller 31, and the pusher 60 pushes the roller 31 to connect with the damping member 50. Among them, the pusher 60 is used to switch the smooth surface 32 and the friction surface 33 on the roller 31 to contact the round tube, and the spinning mechanism 30 is used to grind the round tube during the spinning resetting process, thereby improving the processing efficiency, and the friction surface 33 is in a constantly changing state, thereby improving the durability of the friction surface 33.

The rotating seat 34 is rotatably connected to the machine platform 10, and the slide 35 is slidably connected to the rotating seat 34. The spinning mechanism 30 further includes a screw 36 and a motor 37. The screw 36 is rotatably connected to the rotating seat 34, the screw 36 is screwed to the slide 35, and the output end of the motor 37 is connected to the screw 36 axis. The motor 37 drives the screw 36 to rotate, and then drives the slide 35 to move linearly along the rotating seat 34, and cooperates with the rotation of the rotating seat 34 itself to spin and seal the round tube.

[0031] See also Figure 1-Figure 4 The damping member 50 includes a damping bearing 51 and a friction plate 52. The damping bearing 51 is mounted on the carriage 35, and the friction plate 52 is mounted on the damping bearing 51. The end surface of the roller 31 is movably fitted with the friction plate 52. After the friction plate 52 is fitted to the end surface of the roller 31, the damping bearing 51 is used to make the linear velocity of the roller 31 slower than the linear velocity of the round tube, resulting in relative sliding, so that the friction surface 33 on the roller 31 grinds the round tube and continuously changes the fitting area, which is beneficial to cooling the friction surface 33, reducing wear and improving the durability of the friction surface 33.

[0032] See also Figure 1-Figure 4 The pusher 60 includes a rotating shaft 61, the roller 31 is detachably connected to the rotating shaft 61, and the rotating shaft 61 is movably connected to the slide 35. The pusher 60 also includes an electromagnetic sleeve 62, the rotating shaft 61 is magnetic, and the rotating shaft 61 is magnetically connected to the electromagnetic sleeve 62. The rotating shaft 61 rotates with the roller 31, and the electromagnetic sleeve 62 drives the rotating shaft 61 to move axially through the conversion of electromagnetic force, thereby switching the friction surface 33 or the smooth surface 32 to fit the round tube.

[0033] See also Figure 1-Figure 4 The friction surface 33 is circular and movably inserted into the outer circle of the roller 31.

When the friction surface 33 needs to be replaced, the rotating shaft 61 is pulled out from the roller 31, and then the circular friction surface 33 is removed from the roller 31 for replacement. In this embodiment, the rotating shaft 61 and the roller 31 as well as the friction surface 33 and the roller 31 have a small amount of interference, which can ensure that they do not get loose during circumferential movement.

[0034] See also Figure 1-Figure 4 The friction surface 33 has the same radius as the smooth surface 32. The friction surface 33 has the same radius as the smooth surface 32, so that the smooth surface 32 can be directly moved circumferentially to the friction surface 33 after spinning, so as to improve efficiency.

[0035] The working principle of the high-frequency heating spinning sealing machine is as follows: the feeding mechanism 20 extends one end and rotates at high speed, the high-frequency heating mechanism 40 heats and softens it, and then the motor 37 drives the screw rod 36 to rotate, thereby driving the slide 35 to move linearly along the rotating seat 34, and cooperates with the rotation of the rotating seat 34 itself to spin and seal the round tube with the roller 31. After the sealing is completed, the electromagnetic sleeve 62 drives the rotating shaft 61 to move axially, so that the roller 31 fits with the friction plate 52. The roller 31 is slowed down under the obstruction of the damping bearing 51 and slides and rubs with the round tube. Then, the rotating seat 34 grinds the entire sealing part during the resetting process, and finally the slide 35 is reset.
