[0002] Long bar stock refers to metal bars that are relatively long and have a relatively small diameter. They are commonly used for machining, forging, heat treatment, and other industrial applications. Long bar stock can be classified into various types according to different materials, such as carbon steel bar stock, alloy steel bar stock, stainless steel bar stock, and cemented carbide bar stock. Long bar stock bearing steel is a type of bearing steel material that is rod-shaped and relatively long. It is a key raw material used to manufacture various types of bearings. Its shape facilitates subsequent processing, such as cutting, forging, and turning.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: although long bars are cut, it is impossible to continuously supply bars at a suitable temperature to the cutting components, thereby increasing the cutting time and reducing the cutting efficiency. Therefore, we propose a medium-frequency closed-loop thermal induction heating continuous cutting device for long bar bearing steel to solve the above-mentioned problems. Utility Model Content

[0026] When long bars need to be cut, the heating component 1 is first placed in a preset position, and then the pushing component 2 is fixedly connected to the center of the top surface. This allows the heating component 1 to support the pushing component 2, enabling the operator to place the long bar into the inner cavity of the pushing component 2. The pushing component 2 is then controlled by the PLC controller 4, allowing the output end of the pushing component 2 to continuously push the long bar into the inner cavity. This allows for continuous adjustment of the position of the long bar, facilitating continuous cutting by the cutting component 3. The PLC controller 4 then controls the heating component 1 and the cutting component 3, enabling the heating component 1 to heat the long bar pushed out by the pushing component 2, and the cutting component 3 to cut the heated long bar, thereby improving cutting efficiency.

The output end drives the movable plate 24 to move, which in turn drives the support plate 25 to move, so that the support plate 25 can drive the L-shaped frame 26 to move. Since a connecting column 27 is fixedly connected to the lower part of one side of the L-shaped frame 26, and a push rod 28 is fixedly connected to one end of the connecting column 27, the L-shaped frame 26 can drive the connecting column 27 to move, which in turn drives the push rod 28 to move, so that the push rod 28 can push the long bar. Since an external threaded rod 29 is fixedly connected to the center of one end of the connecting column 27, and an internal threaded hole 210 is opened in the center of one side surface of the push rod 28. This allows the push rod 28 to be rotatably connected to the external threaded rod 29, facilitating disassembly by the operator.

Since guide grooves 211 are provided on one side of the top surface of the placement platform 21 and on both sides of the electric linear slide table 23, and guide plates 212 are fixedly connected to both sides of the bottom surface of the moving plate 24, with the two guide plates 212 connected to the guide grooves 211, the moving plate 24 can drive the guide plates 212 to slide within the guide grooves 211. This allows the guide grooves 211 to limit and guide the guide plates 212, thus providing... The stability of the moving plate 24 is ensured by a mounting frame 213 fixedly connected to one side of the top surface of the placement platform 21, and a first electric telescopic rod 214 embedded in one side of the top surface of the mounting frame 213. Simultaneously, a pressure plate 215 is fixedly connected to the output end of the first electric telescopic rod 214. This allows the mounting frame 213 to support the first electric telescopic rod 214, enabling the pressure plate 215 to move up and down while the output end of the first electric telescopic rod 214 extends and retracts. This allows the pressure plate 215 to fix one end of the long bar, thus providing stability to the long bar and improving its stability during the cutting process.

This allows for continuous adjustment of the long bar's position, facilitating continuous cutting by the cutting component 3. The PLC controller 4 then controls the heating component 1 and the cutting component 3, enabling the heating component 1 to heat the long bar pushed out by the pushing component 2, and the cutting component 3 to cut the heated long bar, thereby improving cutting efficiency.
