Description

Technical Field

[0001] The present invention belongs to the technical field of disc spring processing, and particularly relates to a high-efficiency heat treatment system for disc springs and a processing method thereof. Background Art

[0002] Disc springs, also known as conical springs, are basic components in mechanical equipment and are widely used in fields such as the mechanical industry, railway industry, and construction industry. They are mostly made of cold-rolled or hot-rolled strip steel, sheet metal, or forged blanks and are used in buffer and braking devices that bear large loads. In the production process of disc springs, a heat treatment process is mostly required, and through quenching, the disc springs can have better performance.

[0003] In the prior art, the quenching method of disc springs mostly adopts free quenching. After tempering, the disc springs will have a certain degree of deformation. At the same time, the quenching method is to directly put the high-temperature disc springs into cooling water, and this static quenching method results in poor quenching efficiency and quenching effect. Therefore, we provide a high-efficiency heat treatment system for disc springs and a processing method thereof to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-efficiency heat treatment system for disc springs and a processing method thereof. Through the specific structural design of a heating box, an energy storage component, a self-flow cooling component, a disc conveying mechanism, and a power bearing component, the problems that in the existing free quenching method, the disc springs will have a certain degree of deformation after tempering, and at the same time, the quenching method is to directly put the high-temperature disc springs into cooling water, and this static quenching method results in poor quenching efficiency and quenching effect are solved.

[0011] In some embodiments, the present invention further includes a power bearing assembly; wherein, the power bearing assembly includes a first bearing frame installed on the top of the heating box. A second bearing frame is installed on one side of the heating box close to the diversion track. A hydraulic cylinder is installed on the second bearing frame.

[0013] The present invention has the following beneficial effects: 1. During the quenching process of the present invention, the energy storage elastic member that has completed energy storage starts to release elastic potential energy to drive the energy storage toothed plate to move downward. The downward moving energy storage toothed plate drives the energy storage gear to rotate. At this time, since the conveying drive shaft is not restricted, the energy storage gear drives the conveying drive shaft to rotate synchronously while rotating, and then drives the disc positioning cylinder and each disc therein to rotate synchronously. Under the action of the flowing water and in cooperation with the rotation of the disc positioning cylinder itself, the cooling efficiency of the heated disc can be greatly improved.

[0014] 2. After sleeving one end closed cover on the conveying drive shaft and fixing it with a fastener, a certain number of discs are arranged and sleeved on the conveying drive shaft, so that the positioning pipe on the end closed cover abuts against one disc at the corresponding position. Then, the disc positioning cylinder is sleeved on the conveying drive shaft, so that the limiting groove on the disc positioning cylinder is inserted into the limiting member on the end closed cover. Finally, another end closed cover is sleeved on the conveying drive shaft, and after the limiting groove and the limiting member are inserted and fixed with a fastener, the positioning pipe on this end closed cover also abuts against the corresponding disc. Thus, the positioning and placement of each disc in the disc positioning cylinder are completed. Compared with the free quenching method in the prior art, the positioning heating and quenching method of the present application can effectively avoid the deformation of the disc, and thus is beneficial to ensuring the processing quality of the disc.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0032] For the first specific embodiment, please refer to Figure 1-13, the present invention is a high-efficiency heat treatment system for disc springs, including a heating box 1; an energy storage component 2 is installed on one side of the heating box 1, and a self-flow cooling component 3 is installed on the other side of the heating box 1. The energy storage component 2 includes an energy storage gear 201 rotatably arranged on the outer wall of the heating box 1, and an energy storage tooth plate 202 that can be elastically reset up and down is engaged on one side of the energy storage gear 201; a disc conveying mechanism 4 is installed on the side of the heating box 1 close to the energy storage component 2, and a quenching component 5 is installed on the side of the heating box 1 close to the self-flow cooling component 3; the disc conveying mechanism 4 includes a conveying component 6 and a disc positioning cylinder 7 installed thereon. The conveying component 6 is used to control the reciprocating movement of the disc positioning cylinder 7 between the heating box 1 and the quenching component 5. The conveying component 6 includes a conveying drive shaft 601 for driving the energy storage gear 201 to rotate and a positioning member 602 for locking the conveying drive shaft 601; the quenching component 5 includes a horizontal quenching cylinder 501. A quenching flow channel is arranged on the horizontal quenching cylinder 501. The water inlet end of the quenching flow channel is communicated with the water outlet end of the self-flow cooling component 3. The inner diameter of the horizontal quenching cylinder 501 is the same as the outer diameter of the disc positioning cylinder 7. When the disc positioning cylinder 7 moves into the horizontal quenching cylinder 501, the positioning member 602 releases the limit and controls the disc positioning cylinder 7 to rotate. The water flowing through the quenching flow channel quickly cools the disc positioning cylinder 7. The cooling efficiency of the disc positioning cylinder 7 and each disc therein can be greatly improved by the continuously flowing water.

[0033] In some embodiments, as Figure 4 and Figure 5 shown, the energy storage component 2 further includes an energy storage mounting frame 203 fixedly installed on the outer wall of the heating box 1. A moving seat 204 is slidably arranged on the energy storage mounting frame 203. The energy storage tooth plate 202 is fixed to the bottom of the moving seat 204. An energy storage elastic member 205 connected to the moving seat 204 is installed at the inner top of the energy storage mounting frame 203. The stability of the position where the energy storage tooth plate 202 is located can be maintained under the elastic force of the energy storage elastic member 205. When the conveying drive shaft 601 is controlled to move horizontally in the direction close to the heating box 1, the energy storage gear 201 can be driven to rotate under the action of the conveying drive shaft 601. The rotating energy storage gear 201 drives the energy storage tooth plate 202 to move upward to compress the energy storage elastic member 205. In this process, the conveying drive shaft 601 does not rotate.

[0034] In some embodiments, as Figure 4 and Figure 5As shown, the gravity cooling component 3 includes a diversion track 301 fixedly installed on the outer wall of the heating box 1. One side of the diversion track 301 is fixedly provided with a hollow diversion part 302. One side of the hollow diversion part 302 is communicated with a diversion channel 303. The top of the diversion channel 303 is installed with a hollow diversion box 304. The top of the hollow diversion box 304 is installed with a gravity pipeline 305. A gravity control valve 306 is installed on the gravity pipeline 305. In this embodiment, the gravity pipeline 305 is connected to the bottom of a water storage tank, and both the water storage tank and the heating box 1 are installed on an external frame. A passage opening 101 is opened on one side of the heating box 1 close to the diversion track 301. A horizontal unlocking part 102 is fixed on one side of the heating box 1 close to the energy storage gear 201. The initial state of the whole device is as Figure 3 shown. After the gravity control valve 306 is controlled to open, the cooling water in the water storage tank enters the quenching flow channel along the gravity pipeline 305, the diversion channel 303 and the hollow diversion part 302. The dynamic cooling of the disc positioning cylinder 7 and each disc therein is realized by the cooling water flowing through the quenching flow channel, so as to meet the quenching treatment of each disc after heating. After the quenching treatment is completed, the gravity control valve 306 is controlled to close.

[0035] In some embodiments, as Figure 6 and Figure 7 shown, the conveying component 6 further includes a conveying linkage rod 603 located above the conveying driving shaft 601. One end of the conveying linkage rod 603 is installed with a pneumatic piston 604. The other end of the conveying linkage rod 603 is fixedly provided with a linkage plate 605. The conveying driving shaft 601 is rotatably arranged on the linkage plate 605 (the two are tightly rotatably connected). A sealing disc 606 adapted to the passage opening 101 is installed on the conveying driving shaft 601 through a fastener. A positioning seat 607 is fixedly installed at the end of the conveying driving shaft 601 away from the sealing disc 606. A limiting socket is opened on the circumferential side of the positioning seat 607. During the heating treatment of each disc, the disc positioning cylinder 7 containing several discs is located at the middle position of the inner cavity of the heating box 1. At this time, the sealing disc 606 just fits in the passage opening 101, and the passage opening 101 is sealed through the sealing disc 606. Thus, the heating treatment of each disc can be completed through the sealed heating box 1.

[0036] A first through-opening 608 corresponding to the horizontal unlocking member 102 is formed on the surface of the linkage plate 605. An L-shaped plate 609 is slidably disposed on one side of the linkage plate 605 close to the positioning seat 607. An inclined surface portion 610 adapted to the horizontal unlocking member 102 is fixed inside the L-shaped plate 609 (an electromagnetic plate is installed on the linkage plate 605, and the electromagnet at the bottom of the electromagnetic plate is magnetically attracted to the inclined surface portion 610, not shown in the figure). A second through-opening 611 located below the inclined surface portion 610 is formed on the surface of the L-shaped plate 609. The positioning member 602 is fixed to the bottom of the L-shaped plate 609 and is adapted to the limit socket. A spiral groove 612 is formed on the circumferential side surface of the conveying drive shaft 601. A sliding member fixed to the inner wall of the energy storage gear 201 is engaged in the spiral groove 612. When the conveying drive shaft 601 is controlled to move horizontally towards the heating box 1, under the cooperation of the spiral groove 612 and the sliding member, the horizontally moving conveying drive shaft 601 drives the energy storage gear 201 to rotate. The rotating energy storage gear 201 drives the energy storage rack 202 to move upwards to compress the energy storage elastic member 205. When the inclined surface at the front end of the horizontal unlocking member 102 abuts against the inclined surface portion 610 (at this time, the front end of the horizontal unlocking member 102 is located in the first through-opening 608), as the conveying drive shaft 601 continues to move, the inclined surface portion 610 moving synchronously with the conveying drive shaft 601 is squeezed by the horizontal unlocking member 102 and slides upwards. When the disc positioning cylinder 7 just passes through the through-opening 101 from the heating box 1 and enters the horizontal quenching cylinder 501, the front end of the horizontal unlocking member 102 just disengages from the inclined surface portion 610 and enters the second through-opening 611 to support the L-shaped plate 609. At this time, the positioning member 602 just disengages from the limit socket on the positioning seat 607, and the limiting effect of the positioning member 602 on the conveying drive shaft 601 disappears. During this process, the energy storage elastic member 205 is compressed to store energy.

[0037] After the quenching treatment is completed, the energy storage tooth plate 202 is reset under the action of the energy storage elastic member 205. Subsequently, the conveying drive shaft 601 is controlled to move horizontally in the reverse direction (i.e., move towards the initial position). During this process, since the conveying drive shaft 601 is tightly rotatably connected to the linkage plate 605 and, at the same time, under the elastic force cooperation of the energy storage elastic member 205, the conveying drive shaft 601 does not rotate by itself when there is no external force, thus ensuring that the positioning member 602 is smoothly inserted into the limit insertion opening on the positioning seat 607. During this process, the front end of the horizontal unlocking member 102 disengages from the second through port 611 and re-abuts against the inclined surface portion 610. The L-shaped plate 609 and the inclined surface portion 610 gradually move downward, enabling the positioning member 602 to be inserted into the limit insertion opening. Subsequently, the reverse rotation of the energy storage gear 201 is driven by the conveying drive shaft 601 moving in the reverse direction. The reversely rotating energy storage gear 201 drives the energy storage tooth plate 202 to move downward and stretch the energy storage elastic member 205 to achieve energy storage. When the conveying drive shaft 601 completes the reset, the electromagnet on the electromagnetic plate is controlled to be energized to generate a magnetic attraction force upward on the inclined surface portion 610. After the positioning member 602 disengages from the limit insertion opening, the energy storage tooth plate 202 is moved upward and reset by the elastic force of the energy storage elastic member 205. After the energy storage elastic member 205 returns to its original state, the electromagnet is controlled to be de-energized to demagnetize, and under the action of gravity, the positioning member 602 is re-inserted into the limit insertion opening on the positioning seat 607.

[0038] In some embodiments, such as Figure 3 and Figure 9 shown, the disc conveying mechanism 4 further includes end-sealing assemblies symmetrically arranged; wherein, the end-sealing assembly includes an end-sealing cover 9 sleeved on the conveying drive shaft 601. The end-sealing cover 9 is connected to the conveying drive shaft 601 through fasteners. A positioning tube 10 is fixed on the inner axis of the end-sealing cover 9. A plurality of limiting members 11 are circumferentially arranged in an array on one side of the end-sealing cover 9 close to the positioning tube 10. Limiting grooves 701 are provided at both ends of the disc positioning cylinder 7. The limiting members 11 are in plug-in fit with the corresponding limiting grooves 701; after sleeving an end-sealing cover 9 onto the conveying drive shaft 601 and fixing it through fasteners, a certain number of discs are arranged and sleeved on the conveying drive shaft 601, such that the positioning tube 10 on the end-sealing cover 9 abuts against one disc at the corresponding position. Then, the disc positioning cylinder 7 is sleeved onto the conveying drive shaft 601, such that the limiting grooves 701 on the disc positioning cylinder 7 are plugged with the limiting members 11 on the end-sealing cover 9. Finally, another end-sealing cover 9 is sleeved onto the conveying drive shaft 601, and after the limiting grooves 701 and the limiting members 11 are plugged, it is fixed through fasteners. Thus, the positioning and placement of each disc in the disc positioning cylinder 7 are completed. The above structural design can also facilitate the removal of each processed disc.

[0039] In some embodiments, such as Figure 2 、 Figure 10and Figure 11 As shown in Figure 11 , on one side of the horizontal quenching cylinder 501 close to the heating box 1, a guiding cylinder 502 is fixed. A quenching cavity 503 is formed on the inner wall of the horizontal quenching cylinder 501. A drainage channel 504 communicating with the quenching cavity 503 is installed at the bottom of the horizontal quenching cylinder 501. The drainage channel 504 can be externally connected to a diversion pipeline for collecting the water body after cooling (not shown in the figure). On one side of the horizontal quenching cylinder 501 close to the diversion track 301, an inflow channel 505 communicating with the quenching cavity 503 is installed. The inflow channel 505 is slidably fitted inside the diversion track 301. The quenching flow channel is composed of the quenching cavity 503, the drainage channel 504, and the inflow channel 505. In the initial state or during the quenching process, the inflow channel 505 communicates with the hollow diversion part 302.

[0040] In some embodiments, such as Figure 1 , Figure 12 and Figure 13 As shown in Figure 1 , Figure 12 , and Figure 13 , the present invention further includes a power bearing assembly 8. Among them, the power bearing assembly 8 includes a first bearing frame 801 installed on the top of the heating box 1. On one side of the heating box 1 close to the diversion track 301, a second bearing frame 802 is installed. A hydraulic cylinder 803 is installed on the second bearing frame 802. A horizontal air push pipe 804 is installed on the first bearing frame 801. The conveying linkage rod 603 is slidably fitted with the horizontal air push pipe 804 and the pneumatic piston 604 is fitted inside the horizontal air push pipe 804. A limiting guide rod 805 is fixed between the first bearing frame 801 and the second bearing frame 802. A supporting part 806 connected to the output end of the hydraulic cylinder 803 is slidably arranged on the limiting guide rod 805. The supporting part 806 is sleeved on the horizontal quenching cylinder 501. A supporting rod 807 for supporting the horizontal quenching cylinder 501 is fixed on the circumferential side of the supporting part 806. The horizontal quenching cylinder 501 is installed and fixed through the joint action of the supporting part 806 and the supporting rod 807, and the horizontal quenching cylinder 501 will not rotate during the processing.

[0041] At the top of the first carrier 801, a gas supply device 808 is installed. One gas outlet of the gas supply device 808 is connected to a first gas supply pipe 809, and the other gas outlet of the gas supply device 808 is connected to a second gas supply pipe 810. Gas supply valves 811 are installed on both the first gas supply pipe 809 and the second gas supply pipe 810. The first gas supply pipe 809 and the second gas supply pipe 810 are both communicated with the horizontal gas push pipe 804. On the horizontal gas push pipe 804, exhaust pipes 812 corresponding to the first gas supply pipe 809 and the second gas supply pipe 810 are installed respectively. Exhaust valves 813 are installed on the exhaust pipes 812. On the inner wall of the horizontal gas push pipe 804, a first limiting ring and a second limiting ring are fixed respectively (the pneumatic piston 604 is between the first limiting ring and the second limiting ring. The first limiting ring corresponds to the position of the first gas supply pipe 809, and the second limiting ring corresponds to the position of the second gas supply pipe 810). In the initial state, the pneumatic piston 604 is in contact with the first limiting ring. When quenching treatment is carried out, the pneumatic piston 604 is in contact with the second limiting ring.

[0042] Specific Embodiment 2, the present invention also includes a processing method of a disc spring high-efficiency heat treatment system, which includes the following steps:

[0043] Step 1: Through the retraction movement of the hydraulic cylinder 803, control the supporting part 806 to drive the horizontal quenching cylinder 501 to move to the feeding station far away from the heating box 1. At this time, there is a large unobstructed space between the supporting rod 807 and the heating box 1. Through the combined action of the hydraulic cylinder 803 and the limiting guide rod 805, the supporting part 806 moves smoothly horizontally.

[0044] Step 2: Through the control system, first open the gas supply valve 811 on the first gas supply pipe 809 and the exhaust valve 813 at the position corresponding to the second limiting ring, and then start the gas supply device 808 to continuously supply air into the horizontal gas push pipe 804. The air entering the horizontal gas push pipe 804 pushes the pneumatic piston 604 to move towards the direction close to the second limiting ring until the pneumatic piston 604 abuts against the second limiting ring. During this process, the air on the other side of the pneumatic piston 604 inside the horizontal gas push pipe 804 is discharged along the exhaust pipe 812 corresponding to the second limiting ring (that is, the air on the side of the pneumatic piston 604 close to the second gas supply pipe 810). At this time, control to close the gas supply valve 811 on the first gas supply pipe 809, the gas supply device 808 and the exhaust valve 813 at the position of the second limiting ring. The position where the disc positioning cylinder 7 is installed on the conveying drive shaft 601 is just located at the quenching station (that is, the position where the disc positioning cylinder 7 is installed on the conveying drive shaft 601 is located outside the heating box 1).

[0045] Step 3. After sleeving an end sealing cover 9 onto the conveying drive shaft 601 and fixing it with fasteners, arrange and sleeve a certain number of discs onto the conveying drive shaft 601 so that the positioning tube 10 on the end sealing cover 9 abuts against one disc at the corresponding position. Then, sleeve the disc positioning cylinder 7 onto the conveying drive shaft 601 so that the limiting groove 701 on the disc positioning cylinder 7 is inserted into the limiting member 11 on the end sealing cover 9. Finally, sleeve another end sealing cover 9 onto the conveying drive shaft 601, and after completing the insertion of the limiting groove 701 and the limiting member 11, fix it with fasteners. Thus, the positioning and placement of each disc in the disc positioning cylinder 7 are completed;

[0046] Step 4. Next, through the control system, first open the air supply valve 811 on the second air supply pipe 810 and the air release valve 813 at the corresponding position of the first limiting ring, and then start the air supply device 808 to continuously supply air into the horizontal air push pipe 804. The air entering the horizontal air push pipe 804 pushes the pneumatic piston 604 to move towards the first limiting ring until the pneumatic piston 604 abuts against the first limiting ring. During this process, the air inside the horizontal air push pipe 804 on the other side of the pneumatic piston 604 is discharged along the air release pipe 812 corresponding to the first limiting ring (i.e., the air on the side of the pneumatic piston 604 close to the first air supply pipe 809). At this time, control to close the air supply valve 811 on the second air supply pipe 810, the air supply device 808, and the air release valve 813 at the position of the first limiting ring. The disc positioning cylinder 7 with a number of discs just moves back to the inside of the heating box 1 from the quenching station (i.e., the conveying assembly 6 is reset);

[0047] Step 5. Subsequently, through the forward movement of the hydraulic cylinder 803, control the supporting part 806 to drive the horizontal quenching cylinder 501 to move to the quenching station close to the heating box 1 (the quenching station and the feeding station are at the same position). At this time, the horizontal quenching cylinder 501 is reset, and the guiding cylinder 502 on the horizontal quenching cylinder 501 is close to the heating box 1. Thus, the processing preparation work of the entire equipment is completed. Then, heat-treat the disc positioning cylinder 7 and each disc therein through the heating box 1;

[0048] Step Six: After reaching the heating time set by the control system, control the disc positioning cylinder 7 to pass through the access opening 101 from the inner cavity of the heating box 1 into the horizontal quenching cylinder 501 in the same control manner as in Step Two. At this time, the disc positioning cylinder 7 is just at the quenching station inside the horizontal quenching cylinder 501. During this process, the energy storage elastic member 205 is compressed to store energy. One side of the horizontal quenching cylinder 501 is sealed by the corresponding end closure 9, and the other side of the horizontal quenching cylinder 501 is sealed by the sealing disc 606. Subsequently, control the self-flow control valve 306 to open, and the cooling water in the water storage tank then enters the quenching flow channel along the self-flow pipeline 305, the diversion channel 303, and the hollow diversion portion 302. The dynamic cooling of the disc positioning cylinder 7 and each disc therein is achieved by the cooling water flowing through the quenching flow channel, thereby meeting the quenching treatment of each disc after heating. After the quenching treatment is completed, control the self-flow control valve 306 to close;

[0049] Step Seven: During the quenching process, the energy storage elastic member 205 that has completed energy storage starts to release elastic potential energy to drive the energy storage toothed plate 202 to move downward. The downward moving energy storage toothed plate 202 drives the energy storage gear 201 to rotate. At this time, since the conveying drive shaft 601 is not limited, the energy storage gear 201 drives the conveying drive shaft 601 to rotate synchronously while rotating, thereby driving the disc positioning cylinder 7 and each disc therein to rotate synchronously. With the action of the flowing water and the rotation of the disc positioning cylinder 7 itself, the cooling efficiency of the heated disc can be greatly improved (i.e., the quenching efficiency is improved);

[0050] Step Eight: After the quenching is completed, control the disc positioning cylinder 7 to pass through the access opening 101 from the inside of the horizontal quenching cylinder 501 into the inner cavity of the heating box 1 in the same control manner as in Step Four (i.e., the disc positioning cylinder 7 is reset). Then continue to heat the discs in the disc positioning cylinder 7 through the heating box 1. After heating is completed again, quenching treatment can be carried out again. The specific number of heating and quenching times is set according to the processing technology of the disc spring. After the disc processing of the disc spring is completed, according to the control manner from Step One to Step Three, each disc in the disc positioning cylinder 7 can be taken out and a new disc to be processed can be installed.
