[0009] As a preferred embodiment, a rotating ring is rotatably embedded on the outer surface of one end of the insertion rod, and the rotating ring is interlaced with the support rod.

[0010] Compared with the prior art, the advantages and positive effects of the present invention are:

[0011] The utility model pre-places multiple metal tubes by sleeves on multiple support rods in a cylinder, then installs an extrusion disk on the support rod, and controls the extrusion disk to rotate and move toward one end of the metal tube on the support rod, so that the metal tube is squeezed and fixed between the driven gear and the extrusion disk, and the motor drives the rotating shaft to rotate, and then drives the driving gear to rotate.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1

[0019] like Figure 1-3As shown, the utility model provides a technical solution: a turning device for heat treatment of metal workpieces, comprising a workbench 1, a cylinder 2 is fixedly mounted on the upper surface of the workbench 1, and an electromagnetic heating ring 3 is fixedly mounted on the inner surface of the cylinder 2, the electromagnetic heating ring 3 is used to heat the metal tube placed in the cylinder 2 for heat treatment, a motor 4 is fixed on the surface of the workbench 1 at one side of the cylinder 2, a rotating shaft 5 is fixed on the output shaft of the motor 4, and the rotating shaft 5 is connected to the cylinder 2 through, a driving gear 6 is fixed at one end of the rotating shaft 5, a driven gear 7 is rotated around the outer side of the driving gear 6 on the inner surface of the cylinder 2, and the driven gear 7 is meshed with the driving gear 6, the motor 4 drives the rotating shaft 5 to rotate as a power source, the rotation of the rotating shaft 5 drives the rotation of the driving gear 6, and the rotation of the driving gear 6 drives the simultaneous rotation of multiple driven gears 7 around it, a support rod 8 is fixedly connected to one side surface of the driven gear 7, and the support rod The outer surface of 8 is provided with a threaded groove, and the threaded groove of the support rod 8 is threadedly connected to an extrusion disk 9. Multiple metal tubes are pre-placed on the multiple support rods 8 in the cylinder 2, and then the extrusion disk 9 is installed on the support rod 8, and the extrusion disk 9 is controlled to rotate toward one end of the metal tube on the support rod 8, so that the metal tube is squeezed and fixed between the driven gear 7 and the extrusion disk 9. When the driven gear 7 rotates, it will drive the support rod 8, the extrusion disk 9 and the squeezed and fixed metal tube to rotate together, so that the electromagnetic heating ring 3 can evenly heat the multiple rotating metal tubes. A closing cover 10 is provided on one side of the cylinder 2, and a clamping block 11 and a handle 12 are fixed on the left and right sides of the closing cover 10 respectively. The clamping block 11 is engaged with the cylinder 2. The clamping block 11 is engaged with the cylinder 2, so that the closing cover 10 can stably close the opening on one side of the cylinder 2, and the closing cover 10 can be pulled and moved as a whole by holding the handle 12.

[0020] Example 2

[0021] like Figure 1-3As shown, one side surface of the driven gear 7 and the extrusion disk 9 are provided with anti-skid textures. The anti-skid textures are set to improve the friction of the extrusion surface of the driven gear 7 and the extrusion disk 9, thereby improving the stability of the metal tube when it is extruded and fixed. The outer surfaces of the cylinder 2 and the closing cover 10 are respectively fixedly installed with a No. 1 insulation layer 13 and a No. 2 insulation layer 14. When the electromagnetic heating coil 3 is working normally, the No. 1 insulation layer 13 and the No. 2 insulation layer 14 play a role in heat insulation. One side of the closing cover 10 is fixedly connected to a plug rod 15, and the plug rod 15 is fixed to the support The rod 8 is connected through insertion, and one end of the support rod 8 is supported by the connection between the insertion rod 15 and the support rod 8, thereby improving the stability of the support rod 8 as a whole during rotation. A rotating ring 16 is rotatably embedded on the outer surface of one end of the insertion rod 15, and the rotating ring 16 is connected through insertion with the support rod 8. When the rotating ring 16 is inserted into the support rod 8 together with the insertion rod 15, the rotating ring 16 also rotates during the rotation of the support rod 8, thereby reducing the rotational resistance of one end of the support rod 8 at the insertion rod 15, making it rotate more smoothly.

[0022] Working principle:

[0023] like Figure 1-3 As shown, when the present invention is in use, the user first puts multiple metal tubes on multiple support rods 8 one by one, and makes one end of the metal tubes on the support rods 8 rest against the surface of the driven gear 7, then takes out the extrusion plate 9 and brings it to one end of the support rod 8 and controls its rotation, so that the extrusion plate 9 rotates and moves along the support rod 8 toward one end of the metal tube, and then the metal tube is squeezed and fixed between the driven gear 7 and the extrusion plate 9.

[0024] After squeezing and fixing multiple metal tubes in the cylinder 2, hold the handle 12 to move the closing cover 10 to the opening at one end of the cylinder 2, and push it toward one end of the cylinder 2 so that the blocking block 11 is stuck in the cylinder 2, so that the closing cover 10 can stably close the opening of the cylinder 2. At the same time, the insertion rod 15 and the rotating ring 16 are also inserted into one end of the support rod 8, thereby improving the stability and smoothness of the support rod 8 during rotation.

[0025] When the closing cover 10 completely closes the opening of the cylinder 2, the electromagnetic heating coil 3 and the motor 4 are turned on. After being turned on, the motor 4 will drive the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the rotation of the driving gear 6. The rotation of the driving gear 6 drives the simultaneous rotation of multiple driven gears 7 around it. When the driven gear 7 rotates, it drives the support rod 8, the extrusion disk 9 and the metal tube that is squeezed and fixed to rotate together, so that the electromagnetic heating coil 3 can evenly heat the multiple rotating metal tubes.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
