Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spring production equipment, in particular to an induction heating device for producing high-strength spring steel wire. Background Art
[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under external forces and return to their original shape when the force is removed. During spring steel production, the spring wire needs to be quenched. To ensure efficient quenching, induction heating equipment is used to heat the spring wire to improve quenching efficiency.
[0003] Usually, during the heating and quenching process of spring steel wire, a clamping device is required to move the spring steel wire to the middle of the induction heating equipment. The spring can be quickly heated by utilizing electromagnetic induction and the thermal effect of electric current. However, springs vary in size and shape, and the steel wire will lack toughness after heating, causing the spring to collapse downward after heating, resulting in deformation of the spring. At the same time, the spring deformation will affect its characteristics, thereby affecting the strength of the spring itself. Therefore, we have proposed an induction heating equipment for the production of high-strength spring steel wire. Utility Model Content
[0004] In response to the shortcomings of existing high-strength spring steel wire production induction heating equipment, the utility model provides a high-strength spring steel wire production induction heating equipment, which has the advantage of being able to move outward through a first clamping plate, and can limit the position of the spring according to the size of the spring, and can avoid deformation of the spring when heating the spring, thereby solving the problems raised in the above-mentioned background technology.
[0005] The utility model provides the following technical solution: an induction heating device for producing high-strength spring steel wire, comprising a base, an upper portion of the front end of the base fixedly connected to an induction heating jacket, an inner side of the induction heating jacket fixedly connected to an inner ring, an electromagnetic induction coil installed between the induction heating jacket and the inner ring, a sliding rod movably sleeved on the inside of the base, a bracket foot fixedly connected to the upper portion of the sliding rod, an angle adjustment plate movably sleeved on the upper end of the bracket foot, a positioning rod fixedly connected to the front end of the angle adjustment plate, a sealing sleeve movably sleeved on the outside of the positioning rod, and a first splint installed on the outside of the sealing sleeve via a first diagonal rod.
[0006] Preferably, the front end of the induction heating jacket is in a sealed state, and the inner ring extends to the interior of the induction heating jacket.
[0007] Preferably, the electromagnetic induction coil is spirally sleeved on the outside of the inner ring, a connecting wire is installed on the outside of the electromagnetic induction coil, the connecting wire extends to the outside of the induction heating jacket, and the outside of the connecting wire is connected to a power supply.

[0009] Preferably, a positioning plate is fixedly connected to the outside of the positioning rod, and the sealing sleeve is arranged on the side of the threaded sleeve, while the sealing sleeve is aligned with the front end of the induction heating jacket.
[0010] Preferably, a sliding groove is provided at the lower part of the first splint, and the upper part of the first oblique rod is movably sleeved inside the sliding groove, a second oblique rod is installed at the top end of the first oblique rod, and a threaded sleeve is installed at the end of the second oblique rod, and the threaded sleeve is threadedly sleeved on the outside of the positioning rod.
[0011] Preferably, a second clamping plate is mounted on the upper portion of the first clamping plate via a hinge, a spring is mounted between the first clamping plate and the second clamping plate, and the spring is clamped between the first clamping plate and the second clamping plate.
[0012] Compared with the existing high-strength spring steel wire production induction heating equipment, the utility model has the following beneficial effects:
[0013] 1. The high-strength spring steel wire production induction heating equipment pushes the first clamping plate to move outward by rotating the threaded sleeve, that is, the first clamping plate can be squeezed and limited from the inside of the spring, ensuring that the position of the spring steel wire can be limited according to the different shapes of the spring. At the same time, when the spring is heated, the spring is prevented from being deformed after heating, which affects the subsequent application effect of the spring. At the same time, the equipment adopts a mechanical structure to promote movement and does not contain a metal structure, so as to avoid the positioning rod from being heated and melted when it moves to the inside of the induction heating jacket.
[0014] 2. The high-strength spring steel wire is used to produce induction heating equipment. The spring is sleeved on the outside of the positioning rod. After the positioning rod moves into the inside of the induction heating jacket, the sealing sleeve installed on the outside of the positioning rod can be blocked at the front end of the induction heating jacket to ensure that heat loss is reduced when the equipment is heated.

The upper part of the rod 6 is fixedly connected to a bracket foot 7, and the upper end of the bracket foot 7 is movably sleeved with an angle adjustment plate 8. By pushing the bracket foot 7 to move, the positioning rod 9 can be driven to move to the inner side of the induction heating jacket 2. The front end of the angle adjustment plate 8 is fixedly connected to the positioning rod 9, and the outer part of the positioning rod 9 is movably sleeved with a sealing sleeve 10. By adjusting the position of the sealing sleeve 10, the sealing sleeve 10 is blocked on the outside of the front end of the induction heating jacket 2 to seal the heating area and reduce heat loss. The outside of the sealing sleeve 10 is installed with a first splint 13 through a first oblique rod 12.
[0023] See also Figure 2The front end of the induction heating jacket 2 is in a sealed state, and the inner ring 3 extends to the interior of the induction heating jacket 2. The inner ring 3 is installed on the inner side of the induction heating jacket 2. At the same time, after the spring steel wire is controlled to move to the interior of the induction heating jacket 2, the electromagnetic induction coil 4 can heat the spring steel wire, and the inner ring 3 is arranged on the inner side of the electromagnetic induction coil 4. The inner ring 3 protects the inner position of the electromagnetic induction coil 4.
[0024] See also Figure 2 and Figure 4 The electromagnetic induction coil 4 is spirally sleeved on the outside of the inner ring 3. A connecting wire 5 is installed on the outside of the electromagnetic induction coil 4. The connecting wire 5 extends to the outside of the induction heating jacket 2. At the same time, the outside of the connecting wire 5 is connected to a power supply. The electromagnetic induction coil 4 is sleeved on the outside of the inner ring 3. When the spring steel wire moves to the inside of the inner ring 3, the connecting wire 5 is powered by the power supply. At the same time, the electromagnetic induction coil 4 drives the inside of the inner ring 3 to form an electric field, which can heat the material moved to the inner ring 3 to store the memory, and facilitate the heating and quenching treatment of the formed spring steel wire.
[0025] See also Figure 1 The bracket foot 7 is set at the front end of the induction heating jacket 2, and the angle adjustment plate 8 is located in the middle of the front end of the induction heating jacket 2. A screw is set inside the induction heating jacket 2. The bracket foot 7 is set inside the slide groove opened inside the induction heating jacket 2. By starting the screw, the position of the bracket foot 7 at the front end of the induction heating jacket 2 can be adjusted. By pushing the bracket foot 7, the spring steel wire can be driven to move to the inside of the induction heating jacket 2 to ensure that the spring steel wire maintains stability during positioning.
[0026] See also Figure 1 The outside of the positioning rod 9 is fixedly connected with a positioning plate 11, and the sealing sleeve 10 is arranged on the side of the threaded sleeve 15. At the same time, the sealing sleeve 10 is aligned with the front end of the induction heating jacket 2. The sealing sleeve 10 is installed on the outside of the positioning rod 9, and the spring steel wire is clamped at the front end of the positioning rod 9.

[0027] See also Figure 5The lower part of the first splint 13 is provided with a sliding groove, and the upper part of the first oblique rod 12 is movably sleeved inside the sliding groove, and the top of the first oblique rod 12 is installed with a second oblique rod 14, and the end of the second oblique rod 14 is installed with a threaded sleeve 15, which is threadedly sleeved on the outside of the positioning rod 9 and limited to the outside of the positioning rod 9 by the positioning plate 11. At the same time, the threaded sleeve 15 is rotated, and the threaded sleeve 15 pushes the other end of the second oblique rod 14 to move inward, that is, the distance between the positioning plate 11 and the threaded sleeve 15 is adjusted. After the spacing is adjusted, the height of the first splint 13 can be regulated. According to the different diameters formed inside the spring, the first splint 13 can be pushed to move outward, and the first splint 13 can be controlled to limit the inner side of the spring to ensure that the spring maintains stability during quenching and heating.
[0028] See also Figure 5 A second clamping plate 17 is installed on the upper part of the first clamping plate 13 through a hinge 16, and a spring 18 is installed between the first clamping plate 13 and the second clamping plate 17. The spring is clamped between the first clamping plate 13 and the second clamping plate 17, and the second clamping plate 17 is installed through the outside of the first clamping plate 13. A spring 18 is installed at the rear end of the second clamping plate 17. Under the elastic action of the spring 18, the second clamping plate 17 can push the second clamping plate 17 to limit the position of the outside of the spring. The position of the spring is limited by doubly clamping the inside and outside of the spring by the first clamping plate 13 and the second clamping plate 17 to ensure that the spring will not deform when heated.
[0029] Working principle: When in use, by placing the spring steel wire on the outside of the positioning rod 9, the two sets of threaded sleeves 15 are rotated according to the different diameters of the spring steel wire. The threaded sleeves 15 push the connection between the first oblique rod 12 and the second oblique rod 14 to move outward, and at the same time control the top end of the second oblique rod 14 to move inside the slide groove opened at the lower end of the first splint 13, that is, the position of the first splint 13 outside the positioning rod 9 is adjusted. At this point, the first splint 13 can extrude and limit the spring steel wire from the inside, and at the same time, the second splint 17 extrude and limit the outside of the spring steel wire to ensure that the spring steel wire maintains stability when positioned. At the same time, after pushing the positioning rod 9 to move to the inside of the induction heating jacket 2, the electromagnetic induction coil 4 is energized, and the spring steel wire that can be moved to the middle of the electromagnetic induction coil 4 is heated, thereby improving the efficiency of heating the spring steel wire.
