By setting up the quenching mechanism 7, several cylindrical pipes 3 placed in the quenching box 1 can be quenched. Through the design of the quenching mechanism 7, the positions of multiple cylindrical pipes 3 can be sensed, so that the entire quenching mechanism 7 can quench multiple cylindrical pipes 3 in turn, thereby making the entire quenching device more efficient and more practical.

[0033] In this embodiment, the quenching mechanism 7 also includes a rotating shaft 717 coaxially connected to the output shaft of the motor 716, and two gears 715 are coaxially fixed on the circumferential outer walls of the rotating shaft 717 and the rotating rod 714, respectively, which can smoothly drive the two gears 715 to rotate, and then smoothly drive the screw 72 to rotate.

[0035] Furthermore, the mounting ring 79 corresponds to the positions of the several cylindrical pipe fittings 3 and is adapted in size, the electromagnetic quencher 710 corresponds to the positions of the several cylindrical pipe fittings 3 and is adapted in size, and the camera body 712 corresponds to the positions of the several cylindrical pipe fittings 3, so that the electromagnetic quencher 710 can smoothly quench the several cylindrical pipe fittings 3, and the camera body 712 can smoothly sense the positions of the several cylindrical pipe fittings 3.

[0040] Finally, it should be noted that the electric cylinder 77, electromagnetic quencher 710, camera body 712, motor 716 and other components involved in the utility model are all universal standard parts or components known to technical personnel in this field, and their structures and principles are all known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and compatible controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the utility model. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the field.

[0041] In the specific use of this embodiment, when it is necessary to quench a plurality of cylindrical pipe fittings 3, firstly, the plurality of cylindrical pipe fittings 3 are respectively plugged into the same-side slots on the inner bottom surface of the quenching box 1, and then the motor 716 and the camera body 712 are started through the external PLC. The output shaft of the motor 716 rotates to drive the rotating shaft 717 coaxially connected thereto to rotate, and the rotating shaft 717 rotates to drive the same-side gear 715 coaxially fixed thereto to rotate, and the rotation of the gear 715 drives another gear 715 meshing therewith to rotate, and the rotation of the other gear 715 drives the same-side screw 72 coaxially fixed thereto to rotate, and the rotation of the screw 72 drives the screw 72 coaxially fixed thereto to rotate, and the rotation of the screw 72 drives the connecting plate 73 threadedly connected thereto to move, and the connecting plate 73 moves under the guidance of the guide block 76 and the guide groove on the inner wall at the rear side of the quenching box 1. The movement of the connecting plate 73 drives the moving plate 74 fixed thereto to move, and the movement of the moving plate 74 indirectly drives the movement of the connecting rod 78, and the movement of the connecting rod 78 indirectly drives the movement of the camera body 712 and the electromagnetic quencher 710. When the electromagnetic quencher 710 moves to the top of one of the cylindrical pipe fittings 3, the camera body 712 transmits a signal to the external PLC, and the motor 716 is turned off and the electromagnetic quencher 710 is started through the external PLC, and the piston rod of the electric cylinder 77 is started and controlled through the external PLC to perform telescopic movement, and the movement of the piston rod of the electric cylinder 77 drives the movement of the connecting rod 78 fixed thereto, and the movement of the connecting rod 78 indirectly drives the movement of the electromagnetic quencher 710, so that the electromagnetic quencher 710 can perform a linear reciprocating motion in the vertical direction, and then the cylindrical pipe fitting 3 on the same side can be quenched;

[0042] When the quenching work of the cylindrical pipe 3 is completed, when the electromagnetic quencher 710 moves to the initial position, the electric cylinder 77 and the electromagnetic quencher 710 are closed by the external PLC. According to the above, the above operation can be repeated to quench several other cylindrical pipes 3.
