As the piston rod is continuously processed, the temperature in the environment where the equipment is located will gradually increase. When working in the hot summer season, the effect of cooling measures such as air conditioning decreases, affecting the normal working state of the staff. During the piston rod processing process, the conveying mechanism for the piston rod is relatively fixed. When conveying piston rods of larger or smaller specifications, its applicability is general, which easily leads to the problem of shaking during transportation.

The weight of the piston rod presses on the adjusting ring, and the adaptive spring will be forced to shrink. The adjusting ring that is not in contact with the piston rod will limit the position of the piston rod. Piston rods of different specifications will have different amounts of contact with the adjusting ring during the conveying process, achieving an adaptive effect. It can be used for stable conveying of piston rods of different specifications, improving applicability and avoiding shaking of larger or smaller piston rods. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The rotating rod 504 further includes an inner rod 5041, an adjusting ring 5042 and an adapting spring 5043. The adjusting ring 5042 is provided on the outer side of the inner rod 5041, and the adapting spring 5043 is provided between the inner rod 5041 and the adjusting ring 5042.

[0030] The protective component 6 includes an opening 601, a thermal insulation pad 602 and a metal plate 603. An opening 601 is provided at one end of the protective component 6. The opening 601 allows the processed piston rod to be output from the protective component 6 for the next cooling process.

[0031] In this embodiment, the mounting frame 3 is fixedly mounted on the workbench 2, and there are three groups of electromagnetic induction heating devices 7. The electromagnetic induction heating devices 7 are located in the mounting frame 3 and are fixedly mounted on the workbench 2 in parallel with each other; there are several groups of conveying mechanisms 5, and the two ends of the rotating rod 504 are respectively fixedly mounted in the inner rings of the first bearing seat 501 and the second bearing seat 502, and the motor 503 is fixedly mounted on the workbench 2 and the output end extends into the inner ring of the second bearing seat 502 and is fixedly connected to the rotating rod 504. The piston rod to be processed can be conveyed forward by the rotation of the rotating rod 504; there are several groups of adaptive springs 5043, one end of the adaptive spring 5043 is fixedly connected to the outside of the inner rod 5041, and the adjusting ring 5042 is sleeved on the outside of the inner rod 5041 and fixedly connected to the other end of the adaptive spring 5043. Different specifications can be adapted through the adjusting ring 5042 and the adaptive spring 5043. The piston rod of the grid is stably conveyed to improve applicability and avoid shaking of larger or smaller piston rods; the end of the protective component 6 corresponding to the opening 601 is in an open state and corresponds to the output end of the electromagnetic induction heating device 7; the thermal insulation pad 602 is specifically made of aerogel and embedded between the inner wall and the outer side of the protective component 6, the metal plate 603 is high-strength steel and attached to the outer side of the thermal insulation pad 602, and the structural structure of the mounting frame 3 is consistent with the protective component 6. The thermal insulation effect of the protective component 6 can be guaranteed by the thermal insulation pad 602, and the strength of the protective component 6 and the stability of the thermal insulation pad 602 can be guaranteed by the metal plate 603; there is an electrical connection between the electromagnetic induction heating device 7 and the control device 4, and there is an electrical connection between the control device 4 and the external power supply.

[0032] The working principle and use process of the present invention: the operating principles of the electromagnetic induction heating device 7, the motor 503, and the control device 4, and the electronic control circuit are all inherent in the current field and are well known to the personnel in the current field, so they are not described in detail here. In actual use, the equipment is placed in a suitable position and connected to an external power supply. The motor 503 and the electromagnetic induction heating device 7 are started through the control device 4. The piston rod subject to be processed is installed on the conveying mechanism 5 on the same side of the frame 3 and the control device 4, and the piston rod is made to correspond to the input end of the electromagnetic induction heating device 7. After the piston rod is placed on the conveying mechanism 5, its weight is pressed on the adjusting ring 5042. At the same time, the adapting spring 5043 will be forced to contract, and the adjusting ring 5042 that is not in contact with the piston rod will limit the piston rod. The position of the piston rod ensures that the piston rod continues to be transported in the same direction. Piston rods of different specifications have different contacts with the adjusting ring 5042 during the transportation process, achieving an adaptive effect. Piston rods of different specifications can be used for stable transportation, improving applicability and avoiding shaking of larger or smaller piston rods. As the transportation mechanism 5 continues to transport, the piston rod is finally heated by the electromagnetic induction heating device 7, and after heating is completed, it passes through the protective component 6. The transportation mechanism 5 in the protective component 6 has the same transportation effect. The high temperature emitted by the heated piston rod itself will be blocked by the thermal insulation pad 602 in the protective component 6. The aerogel material thermal insulation pad 602 effectively blocks the temperature from dissipating, avoids affecting the ambient temperature of the equipment, avoids affecting the staff, and ensures the working status of the drying personnel.
