Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment devices, in particular to a high carbon steel heat treatment device. Background Art

[0002] The reason why high carbon steel needs heat treatment is mainly because through proper heat treatment, it can have high strength and hardness, high elastic limit and fatigue limit. There are different equipment according to different process requirements. The main methods of surface heat treatment are flame quenching and induction heating heat treatment equipment. Among them, high-frequency induction heating equipment is a commonly used heat treatment equipment. It uses electromagnetic induction to generate current inside the heated material, relying on the energy of these eddy currents to achieve the purpose of rapid heating.

[0003] Most of the existing ultra-high frequency induction heating equipment for heat treatment fixes the materials manually, which not only makes the fixing effect poor, but also increases the manual labor, thereby reducing the use efficiency of the high-frequency induction heating equipment. In addition, most high-frequency induction heating equipment cannot be adjusted according to the height of the material, thereby reducing the practicality of the high-frequency induction heating equipment.

[0004] After searching, the Chinese utility model patent with publication number: CN214115628U discloses an ultra-high frequency induction heating device for heat treatment, including a high-frequency induction machine body, and the coordinated use of a second motor, a second moving rod and a clamping block can completely fix the top of the material, thereby reducing the phenomenon of manual placement and fixing, thereby reducing manpower consumption, and thus improving the working efficiency of the high-frequency induction heating device, and the coordinated use of the first motor, the first connecting block and the first moving rod can adjust the height of the second moving plate according to the height of the material, which not only prevents the phenomenon of collision between the material and the second moving plate due to excessive height, but also prevents the phenomenon of the clamping block not being fixed to the material due to excessive lowness of the material, thereby improving the preventiveness and adjustability of the high-frequency induction heating device.

[0005] In the above technical solution, the material is clamped up and down by a clamping device. However, during use, after the material is heated at high temperature, when it is necessary to take the material, the clamping blocks at the upper and lower ends of the material need to be loosened. Once the clamping blocks at the upper and lower ends are loosened, the material is prone to tilt, causing the material to contact the induction coil, resulting in excessive induced current, local high temperature burning the induction coil, and other problems. Moreover, in the above technical solution, the induction heating coil is fixed in position relative to the support seat at the bottom. During heat treatment, only a fixed area of ​​the heated material can be fixed, affecting the use of heat treatment of other parts of the material. Utility Model Content

[0006] The purpose of the utility model is to provide a high carbon steel heat treatment device to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high carbon steel heat treatment device, comprising: a base and an induction heating coil, wherein induction heating coils are fixed on both sides of the top of the base, linear electric slide rails are provided on the ground at both ends of the induction heating coil, a slide seat is provided on the top of the linear electric slide rail, bearing seats are fixed on both sides of the slide seat, a lower support wheel is provided between the bearing seats, guide columns are provided at the four corners of the top surface of the slide seat, a lifting plate is provided on the outside of the guide column, an upper pressure wheel is rotatably provided on the bottom surface of the lifting plate, a top plate is provided on the top of the guide column, and an electric hydraulic cylinder is provided on the top of the top plate.

[0008] Furthermore, a driving motor is fixed to the outer wall of the bearing seat located on one side, and one end of the power output shaft of the driving motor is fixedly connected to one end of the lower supporting wheel.

[0009] Furthermore, the outer walls of the lower support wheel and the upper pressure wheel are both provided with convex strips, and there are a plurality of convex strips, and the plurality of convex strips are evenly arranged circumferentially on the outer wall of the lower support wheel, and the convex strips are evenly arranged circumferentially on the outer wall of the upper pressure wheel.

[0010] Furthermore, the top surface of the lower support wheel is located more than 10 mm above the bottom inner wall of the induction heating coil.

[0011] Furthermore, the bottom end of the piston rod of the electric hydraulic cylinder is fixedly connected to the top of the top plate, and through holes are opened at the four corners inside the lifting plate and located outside the guide pillars.

[0012] Furthermore, the length of the lower supporting wheel is smaller than the inner diameter of the induction heating coil.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model realizes that when the high-carbon steel heat treatment device is used, through the induction heating coil, the linear electric slide rail and the lower support wheel, when the high-carbon steel material needs to be subjected to induction electromagnetic heating, the material passes through the induction heating coil and is placed above the lower support wheels on both sides. Then, the lifting plate is driven down by the electric hydraulic cylinder, so that the upper pressing wheel is also lowered, and the material is pressed and fixed between the upper pressing wheel and the lower support wheel. When the heat treatment position of the material needs to be adjusted, the linear electric slide rails at both ends of the induction heating coil simultaneously drive the slide seat to move, thereby driving the components above the slide seat to move together, thereby adjusting the position of the material relative to the induction heating coil, which is convenient for local heat treatment of different parts of the material.

[0015] At the same time, after the heat treatment is completed, when the material needs to be taken, the electric hydraulic cylinder drives the lifting plate to rise, thereby driving the upper pressing wheel to rise, so that the upper pressing wheel is separated from the material, and then the drive motor is started to drive the lower supporting wheel to rotate, and the friction between the lower supporting wheel and the material drives the material to move to one side, so that the material can be taken out smoothly from the induction heating coil to prevent the material from contacting the induction heating coil and causing danger.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-Figure 4The utility model provides a technical solution: a high carbon steel heat treatment device, comprising: a base 1 and an induction heating coil 2, the induction heating coil 2 is fixed on both sides of the top of the base 1, a linear electric slide 3 is arranged on the ground at both ends of the induction heating coil 2, a slide seat 4 is arranged on the top of the linear electric slide 3, a bearing seat 5 is fixed on both sides of the slide seat 4, a lower support wheel 6 is arranged between the bearing seats 5, a guide column 7 is arranged at the four corners of the top surface of the slide seat 4, a lifting plate 8 is arranged on the outside of the guide column 7, an upper pressing wheel 11 is arranged on the bottom surface of the lifting plate 8 for rotation, a top plate 9 is arranged on the top of the guide column 7, and an electric hydraulic cylinder 10 is arranged on the top of the top plate 9. The lifting plate 8 is driven down by the electric hydraulic cylinder 10, so that the upper pressing wheel 11 is lowered together, and the material is pressed and fixed between the upper pressing wheel 11 and the lower support wheel 6. When the heat treatment position of the material needs to be adjusted, the linear electric slides 3 at both ends of the induction heating coil 2 simultaneously drive the slide seat 4 to move, thereby driving the components above the slide seat 4 to move together, so as to adjust the position of the material relative to the induction heating coil 2, so as to facilitate the local heat treatment of different parts of the material.

[0023] A driving motor 12 is fixed to the outer wall of the bearing seat 5 on one side, and one end of the power output shaft of the driving motor 12 is fixedly connected to one end of the lower supporting wheel 6. The lower supporting wheel 6 is driven to rotate by the driving motor 12, which is convenient for taking materials.

[0024] The outer walls of the lower support wheel 6 and the upper pressing wheel 11 are both provided with convex strips. There are several convex strips, which are evenly arranged circumferentially on the outer wall of the lower support wheel 6, and the convex strips are evenly arranged circumferentially on the outer wall of the upper pressing wheel 11. The convex strips contact the material to reduce the wear of the lower support wheel 6 and the upper pressing wheel 1.

[0025] The top surface of the lower support wheel 6 is located more than 10 mm above the bottom inner wall of the induction heating coil 2 to prevent the material from being too far away from the induction heating coil 2, causing excessive induced current and local high temperature to burn the induction coil.

[0026] The bottom end of the piston rod of the electric hydraulic cylinder 10 is fixedly connected to the top of the top plate 9, and through holes are opened at the four corners inside the lifting plate 8 and located outside the guide pillars 7 for guiding the lifting plate 8 when it is lifted or lowered.

[0027] The length of the lower support wheel 6 is smaller than the inner diameter of the induction heating coil 2, so that when placing the material, the width of the material can be compared with the width of the lower support wheel 6. When the width of the material is greater than the width of the lower support wheel 6, it means that the material width is wider and is not suitable for using this induction heating coil 2. This prevents the material from being too close to the induction heating coil 2, causing the induced current to be too large, and local high temperature to burn the induction coil.

[0028] Working principle: When the high-carbon steel heat treatment device is used, when the high-carbon steel material needs to be subjected to induction electromagnetic heating, the material is passed through the induction heating coil 2 and placed above the lower support wheels 6 on both sides. Then, the lifting plate 8 is driven down by the electric hydraulic cylinder 10, so that the upper pressing wheel 11 is also lowered, and the material is pressed and fixed between the upper pressing wheel 11 and the lower support wheel 6. When the heat treatment position of the material needs to be adjusted, the linear electric slide rails 3 at both ends of the induction heating coil 2 simultaneously drive the slide 4 to move, thereby driving the components above the slide 4 to move together, thereby adjusting the position of the material relative to the induction heating coil 2, which is convenient for local heat treatment of different parts of the material;

[0029] At the same time, after the heat treatment is completed, when the material needs to be taken out, the electric hydraulic cylinder 10 drives the lifting plate 8 to rise, thereby driving the upper pressing wheel 11 to rise, so that the upper pressing wheel 11 is separated from the material, and then the driving motor 12 is started to drive the lower supporting wheel 6 to rotate, and the friction between the lower supporting wheel 6 and the material drives the material to move to one side, so as to facilitate the smooth removal of the material from the induction heating coil 2 and prevent the material from contacting the induction heating coil 2 and causing danger.

[0030] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
