Figure 5 , which shows the structure when the quenching die applicable to large-sized ring-shaped parts in the embodiment of the present invention disengages from the workpiece.

[0035] This embodiment provides a quenching die 200 applicable to large-sized ring-shaped parts. The quenching die 200 applicable to large-sized ring-shaped parts is applied in a quenching device.

[0036] Among them, the quenching device includes a press body, a pull rod 10, and a quenching die 200 applicable to large-sized ring-shaped parts. The quenching die 200 applicable to large-sized ring-shaped parts includes a first die unit 210. The first die unit 210 includes a first cone 211 and a first module 212. The first module 212 is movably connected to the conical outer peripheral surface of the first cone 211. Along the axis direction of the first cone 211, the first cone 211 is provided with a first through hole 213 for cooperating with the pull rod 10 of the quenching device. The first cone 211 is used to move along its axis direction under the driving action of the pull rod 10 and drive the first module 212 to move in a direction perpendicular to the axis of the first cone 211.

[0037] The first die unit 210 is connected to the press body. The pull rod 10 is movably connected to the press body. The pull rod 10 cooperates with the first through hole 213. The pull rod 10 is used to drive the first cone 211 to move along its axis direction, so as to drive the first module 212 to move in a direction perpendicular to the axis of the first cone 211, so that the first module 212 abuts against the workpiece 20 sleeved on the quenching die 200 applicable to large-sized ring-shaped parts or separates the first module 212 from the workpiece 20 sleeved on the quenching die 200 applicable to large-sized ring-shaped parts.

[0038] Please refer to Figures 1-5 , the working principle of this quenching equipment is:

[0039] During the quenching process of workpiece 20, the first die unit 210 is connected to the press body, and the workpiece 20 is sleeved on the first die unit 210. Since the first cone 211 is provided with a first through hole 213 for cooperating with the pull rod 10, the pull rod 10 that is movably connected to the press body can extend into the first through hole 213 during the process of moving relative to the press body, and by driving the first cone 211 to move along its own axis direction, the first module 212 can be brought into contact with or separated from the workpiece 20, thereby completing the support of the workpiece 20 or demolding.

[0040] Specifically, when the first module 212 expands outward in a direction perpendicular to the axis of the first cone 211 under the driving action of the first cone 211, so that the outer diameter of the quenching die 200 suitable for large ring-shaped parts increases, the first module 212 can be tightly pressed against the inner ring of the workpiece 20, thereby being able to support the workpiece 20 during the quenching process of the workpiece 20 to prevent the workpiece 20 from deforming during quenching. Similarly, when the first module 212 retracts inward in a direction perpendicular to the axis of the first cone 211 under the driving action of the first cone 211, so that the outer diameter of the quenching die 200 suitable for large ring-shaped parts decreases, the first module 212 can be separated from the workpiece 20, thereby being able to play a role in demolding, so as to facilitate the demolding of the workpiece 20 and improve the demolding efficiency of the workpiece 20.

[0041] This setting method enables the pull rod 10 of the quenching equipment to drive the first cone 211 to move during quenching, thereby playing a supporting role for the workpiece 20; it can also drive the first cone 211 to move after quenching is completed, and then perform the demolding action, so that the functions of support and demolding can be completed through the movement of the pull rod 10, which can simplify the structure of the quenching equipment, reduce the operation difficulty of demolding, and improve the demolding efficiency.

[0042] It should be noted that the quenching die 200 suitable for large ring-shaped parts can be used to meet the quenching requirements of large ring-shaped workpieces 20.

[0043] Furthermore, please refer to Figures 1-5, in this embodiment, the quenching die 200 applicable to large-sized ring-shaped parts further includes a second die unit 220. The second die unit 220 includes a second cone 221 and a second module 222. The second module 222 is movably connected to the conical outer peripheral surface of the second cone 221. Along the axial direction of the second cone 221, a second through hole 223 for cooperating with the pull rod 10 is provided in the second cone 221. The axis of the first cone 211 coincides with the axis of the second cone 221. When the first die unit 210 and the second die unit 220 are closed, the second cone 221 is used to move along its axial direction under the driving action of the pull rod 10 and drive the second module 222 to move in a direction perpendicular to the axis of the second cone 221. The second cone 221 is further used to drive the first cone 211 to move along the axial direction of the first cone 211 under the driving action of the pull rod 10.

[0044] The quenching equipment further includes a lifting mechanism connected to the press body. The second die unit 220 is connected to the lifting mechanism. The lifting mechanism is used to drive the second die unit 220 to move relative to the press body so that the first die unit 210 and the second die unit 220 are closed or separated.

[0045] The pull rod 10 cooperates with the first through hole 213 and the second through hole 223. The pull rod 10 is used to drive the first cone 211 and the second cone 221 to move along their axial directions to drive the first module 212 and the second module 222 to move in a direction perpendicular to the axis of the first cone 211, so as to make the first module 212 and the second module 222 abut against the workpiece 20 sleeved on the quenching die 200 applicable to large-sized ring-shaped parts or make the first module 212 and the second module 222 separate from the workpiece 20 sleeved on the quenching die 200 applicable to large-sized ring-shaped parts.

[0046] Specifically, when the pull rod 10 moves towards the direction close to the press body under the action of an external force, it will drive the second cone 221 to move along its own axis towards the direction close to the first cone 211, so as to be able to drive the second module 222 to expand outwards in the direction perpendicular to the axis of the second cone 221. Thus, the outer diameter of the second die unit 220 can be increased. At this time, the second module 222 can be in tight contact with the inner ring of the workpiece 20, so as to be able to support the workpiece 20 during the quenching process of the workpiece 20, so as to avoid deformation of the workpiece 20 during the quenching process. At the same time, the movement of the second cone 221 can drive the first cone 211 in contact with the second cone 221 to move in the same direction. Thus, the first module 212 can be driven by the first cone 211 to expand outwards in the direction perpendicular to the axis of the first cone 211. Therefore, the outer diameter of the first die unit 210 can be increased. At this time, the first module 212 can be in tight contact with the inner ring of the workpiece 20, so as to be able to support the workpiece 20 during the quenching process of the workpiece 20, so as to avoid deformation of the workpiece 20 during the quenching process. That is, when the pull rod 10 moves in the direction close to the press body, it can drive the first die unit 210 and the second die unit 220 to be in tight contact with the inner ring of the workpiece 20, so as to be able to support the workpiece 20 during the quenching process of the workpiece 20, so as to avoid deformation of the workpiece 20 during the quenching process.

[0047] When the pull rod 10 moves towards the direction close to the quenching die 200 applicable to large-sized ring-shaped parts under the action of an external force, it will drive the second cone 221 to move along its own axis towards the direction away from the first cone 211, so as to be able to drive the second module 222 to retract in the direction perpendicular to the axis of the second cone 221. Thus, the outer diameter of the second die unit 220 can be reduced. At this time, the second module 222 can be separated from the inner ring of the workpiece 20, so as to be able to play a role in demoulding after the workpiece 20 is quenched, so as to quickly separate the quenching die 200 applicable to large-sized ring-shaped parts from the workpiece 20. At the same time, the movement of the pull rod 10 can drive the first cone 211 to move in the same direction. Thus, the first module 212 can be driven by the first cone 211 to retract in the direction perpendicular to the axis of the first cone 211. Therefore, the outer diameter of the first die unit 210 can be reduced. At this time, the first module 212 can be separated from the inner ring of the workpiece 20, so as to be able to play a role in demoulding after the workpiece 20 is quenched, so as to quickly separate the quenching die 200 applicable to large-sized ring-shaped parts from the workpiece 20. That is, when the pull rod 10 moves towards the quenching die 200 applicable to large-sized ring-shaped parts, it can drive the first die unit 210 and the second die unit 220 to be separated from the inner ring of the workpiece 20, so as to be able to play a role in demoulding after the workpiece 20 is quenched, so as to facilitate the demoulding efficiency of the workpiece 20.

[0048] It should be noted that when the quenching die 200 applicable to large-sized ring-shaped parts includes the second die unit 220, since the second die unit 220 is connected to the lifting mechanism, the lifting mechanism can drive the second die unit 220 to move relative to the press body, so that the first die unit 210 and the second die unit 220 can be closed or separated. When the pull rod 10 drives the quenching die 200 applicable to large-sized ring-shaped parts to abut against or separate from the workpiece 20, the first die unit 210 and the second die unit 220 must be in the closed state. That is, before quenching the workpiece 20, the workpiece 20 needs to be sleeved on the quenching die 200 applicable to large-sized ring-shaped parts, and the lifting mechanism is used to drive the second die unit 220 to move towards the direction close to the press body, so that the second die unit 220 and the first die unit 210 are closed; moreover, it is necessary to make the pull rod 10 move towards the direction close to the quenching die 200 applicable to large-sized ring-shaped parts relative to the press body, cooperate with the first through hole 213 of the first cone 211 and the second through hole 223 of the second cone 221, and lock the pull rod 10 with the second die unit 220, so that the pull rod 10 can drive the second cone 221 to move.

[0049] In summary, based on the above structure, the pull rod 10 of the quenching equipment can drive the quenching die 200 applicable to large-sized ring-shaped parts to move during the working process, thereby playing a supporting role for the workpiece 20; it can also drive the quenching die 200 applicable to large-sized ring-shaped parts to move after quenching is completed, thereby completing the demoulding action. Thus, the functions of supporting the workpiece 20 and demoulding can be completed through the movement of the pull rod 10, which can simplify the structure of the quenching equipment, reduce the operation difficulty of demoulding, and improve the demoulding efficiency.

[0050] Further, please refer to Figures 1-3, in this embodiment, in order to enable the first cone 211 and the second cone 221 to drive the first module 212 and the second module 222 to move in a direction perpendicular to the axis of the first cone 211 along their own axial directions respectively, the outer peripheral surfaces of the first cone 211 and the second cone 221 are set to be conical, so that the mating surfaces of the first cone 211 and the first module 212 are inclined surfaces, and the mating surfaces of the second cone 221 and the second module 222 are inclined surfaces. Based on this, in order to guide the relative movement between the first module 212 and the first cone 211 and between the second module 222 and the second cone 221, along the axis direction of the first cone 211, first guide grooves 215 and second guide grooves 225 are respectively formed on the outer peripheral surfaces of the first cone 211 and the second cone 221; the quenching die 200 applicable to large ring-shaped parts further includes a first guide member 216 connected to the first module 212 and a second guide member 226 connected to the second module 222; the first guide member 216 is slidably engaged with the first guide groove 215, and the second guide member 226 is slidably engaged with the second guide groove 225.

[0051] When setting the guide members, in this embodiment, the first guide member 216 includes a first connecting bolt 217 and a first guide sleeve 218; the first connecting bolt 217 is connected to the first module 212, and the first guide sleeve 218 is sleeved on the first connecting bolt 217 and is slidably engaged with the first guide groove 215; the second guide member 226 includes a second connecting bolt 227 and a second guide sleeve 228; the second connecting bolt 227 is connected to the second module 222, and the second guide sleeve 228 is sleeved on the second connecting bolt 227 and is slidably engaged with the second guide groove 225.

[0052] Further, please refer to Figures 1-3, in this embodiment, when setting the first cone 211, in order to enable the movement of the pull rod 10 to drive the first cone 211 to move for the demolding action, thus, a first abutting platform 214 that abuts against the pull rod 10 is provided on the inner peripheral surface of the first through hole 213. The first abutting platform 214 is used to abut against the pull rod 10 when the pull rod 10 moves in the direction close to the quenching die 200 applicable to large ring-shaped parts, so that the pull rod 10 can drive the first cone 211 to move in the same direction. It should be noted that in this embodiment, since the first cone 211 abuts against the second cone 221, when the pull rod 10 moves in the direction close to the quenching die 200 applicable to large ring-shaped parts and drives the first cone 211 to move in the same direction, it can drive the second cone 221 to move in the same direction. In other embodiments of the present invention, for the same principle of setting the first abutting platform 214, the same structure can also be provided in the second through hole 223 to abut against the pull rod 10 when the pull rod 10 moves in the direction close to the quenching die 200 applicable to large ring-shaped parts, so that the pull rod 10 can drive the second cone 221 to move in the same direction.

[0053] Further, please refer to Figures 1-3 , in this embodiment, in order to enable the pull rod 10 to drive the second cone 221 to move in the same direction when moving in the direction close to the press body, a second abutting platform 224 that abuts against the second module 222 is provided on the second cone 221. The second abutting platform 224 is used to abut against the second module 222 when the pull rod 10 moves in the direction close to the press body, thereby driving the second cone 221 in the direction close to the press body. And when the second cone 221 moves in the direction close to the press body, since the first cone 211 abuts against the second cone 221, the movement of the second cone 221 can drive the first cone 211 to move in the same direction.

[0054] It should be noted that when setting the second abutting platform 224, in order to enable the second abutting platform 224 to abut against the second module 222 when the pull rod 10 moves in the direction close to the press body to drive the second cone 221 to move in the direction close to the press body, along the axial direction of the second cone 221, the second abutting platform 224 is located at one end of the second cone 221 away from the first die unit 210. And to improve the stability of the abutment between the second abutting platform 224 and the second cone 221, the second abutting platform 224 is an annular platform arranged around the axial direction of the second cone 221.

[0055] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
