Description

Technical Field

[0001] This utility model belongs to the technical field of high-frequency quenching machines, specifically relating to a high-frequency quenching machine for piston rods. Background Technology

[0002] The working principle of a high-frequency quenching machine is based on electromagnetic induction heating technology. When a high-frequency current passes through the induction coil, an alternating magnetic field is generated around the coil. The metal workpiece placed inside the coil is affected by this magnetic field, and eddy currents are generated inside, which in turn generate heat. By adjusting the current frequency and power, the heating temperature and time can be precisely controlled to achieve rapid heating of the workpiece surface. After heating, the workpiece is rapidly cooled by spraying water or other cooling media, so that a hardened martensitic structure is formed on the metal surface.

[0003] Patent application number 202221641714.7 discloses a high-frequency quenching device for piston rods. After the piston rod is quenched, the distance between the cooling fan and the piston rod can be adjusted as needed to improve the cooling effect. Moreover, the operation of placing the piston rod into the quenching furnace is very simple. In conjunction with the above application, and compared with existing handheld high-frequency quenching machines, the copper heating induction ring used for heating is easily damaged by bumps during storage. If the copper heating induction ring is deformed during storage, it can easily damage the device or affect the heating efficiency of the quenching machine, thereby reducing the practicality and safety of the device. Therefore, we propose a high-frequency quenching machine for piston rods. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figure 1 and Figure 2This utility model provides a technical solution: a high-frequency quenching machine is a device that uses the heat generated by high-frequency current to rapidly heat and cool metal materials. It is widely used in various heat processing technologies such as metal quenching and surface heat treatment, annealing, brazing, smelting, hot forging, hot assembly, thermal spraying, and polymer diffusion welding. A piston rod high-frequency quenching machine includes a high-frequency main unit 100. A touch screen display 101 is installed on the top of the front surface of the high-frequency main unit 100. A flexible cable 102 is connected to the bottom of the rear surface of the high-frequency main unit 100. A connecting handle 103 is fixedly installed at the other end of the flexible cable 102. A copper heating induction ring 104 is installed at the other end of the connecting handle 103. The other end of the connecting handle 103 is fixedly... There is a connecting block 204, and a copper heating induction ring 104 is fixed on the connecting block 204. A protective cover plate 200 is also provided on the outside of the copper heating induction ring 104. One end of the protective cover plate 200 is provided with an opening and closing rotating seat 201. A rotating shaft 205 is provided between the opening and closing rotating seat 201 and the connecting block 204. The opening and closing rotating seat 201 and the connecting block 204 are rotated and installed through the rotating shaft 205. The surface of the opening and closing rotating seat 201 is also provided with a positioning arc-shaped limiting groove 202. When the high-frequency quenching machine in this application is used to process the piston rod, the equipment is started, the operator holds the connecting handle 103, and then the piston rod to be quenched is placed into the copper heating induction ring 104. The piston rod is then heated by induction through the copper heating induction ring 104.

[0023] Specifically, a hand-tightening limit bolt 203 is screwed onto the connecting block 204 through the arc-shaped limiting groove 202. The connecting block 204 and the opening / closing rotating seat 201 are fixed together by the hand-tightening limit bolt 203. When the opening / closing rotating seat 201 rotates, the angle is limited by the arc-shaped limiting groove 202 and the hand-tightening limit bolt 203 to ensure that the rotation angle of the protective cover 200 is fixed. The protective cover 200 rotates through the opening / closing rotating seat 201 and the connecting block 204, and the rotation controls the protection of the copper heating induction ring 104. When using the quenching machine, the hand-tightening limit bolt 203 on the opening / closing rotating seat 201 can be loosened, and then the connecting block 204 can be... The protective cover 200 is rotated by the pivot 205. When the protective cover 200 rotates, it can also be limited by the arc-shaped limiting groove 202 and the hand-tightening limiting bolt 203. The limiting can ensure the rotation angle of the protective cover 200. After the protective cover 200 rotates 90 degrees to expose the copper heating induction ring 104, the hand-tightening limiting bolt 203 can be tightened to fix it. After use, the same operation steps can be used to rotate the protective cover 200 to the outside of the copper heating induction ring 104 for protection. The protective cover 200 prevents the copper heating induction ring 104 from being damaged by bumps during storage, thereby improving the safety and functionality of the device.

[0024] Example 2

[0025] Please see Figure 1 and Figure 3 This utility model provides a technical solution: a high-frequency quenching machine for piston rods, wherein a friction-resistant sleeve 300 is fitted onto a flexible cable 102, and a recessed anti-wear groove 301 is formed on the surface of the friction-resistant sleeve 300. A rotatable anti-wear ball 302 is embedded in the anti-wear groove 301. Multiple friction-resistant sleeves 300 are equidistantly arranged on the flexible cable 102, and anti-wear balls 302 are arranged on the inner side of each friction-resistant sleeve 300. During use, the flexible cable 102 will rub against the ground during dragging. The friction-resistant sleeve 300 structure on the flexible cable 102 prevents friction during the use of this device. The anti-friction sleeves 300 are equidistantly fitted onto the flexible cable 102. During dragging, the anti-friction sleeves 300 contact the ground, and anti-wear balls 302 are embedded in the anti-friction sleeves 300. During dragging, the anti-wear balls 302 can also be moved, changing the moving friction into rolling friction, thereby improving the convenience of dragging. Furthermore, positioning rings 303 are set at both ends of the anti-friction sleeves 300. The flexible cable 102 is clamped on the inner side of the positioning rings 303 by positioning elastic pieces 304, which not only ensures the stability of the anti-friction sleeves 300 but also allows for movement adjustment, further improving the practicality and safety of the device.

[0026] Specifically, the anti-friction sleeve 300 has an integrated positioning ring 303 at both ends. A positioning elastic piece 304 is fixedly installed on the inner side of the positioning ring 303. When the anti-friction sleeve 300 is put on the flexible cable 102, the flexible cable 102 is positioned by the positioning elastic piece 304 set on the inner side of the positioning ring 303. The flexible clamping method can be easily moved and adjusted, thereby improving the convenience of adjustment.
