Description

Technical Field

[0001] The present invention belongs to the technical field of salt bath quenching treatment, and specifically relates to an ADI material heat treatment preparation device and method. Background Art

[0002] Austempered ductile iron (ADI) is a high-performance material. During its preparation, the austenitized cast iron workpiece must be quickly transferred to a salt bath for austempering and then held at a constant temperature for a period of time. Traditional heat treatment equipment presents the following challenges during this transfer process:

[0003] A: The transfer speed is slow, resulting in a large drop in the workpiece temperature, affecting the structural transformation;

[0004] B: The traditional transfer track is a one-piece track. Not only is the material selection difficult (due to the large temperature difference between the two ends), but also the good thermal conductivity of metal causes the heat in the heating furnace to transfer quickly to the salt bath, resulting in heat waste.

[0005] C: The traditional workpiece transfer path is completely exposed to the air, causing the workpiece to come into contact with oxygen, which can easily cause surface oxidation of the workpiece. Summary of the Invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an ADI material heat treatment preparation device and method thereof. This solution replaces the traditional single-track design with a split dual-track design. On the one hand, it can cut off the middle heat conduction path, and on the other hand, it can also select different materials to adapt to their respective working conditions; not only that, the present invention also isolates the transfer path from the outside world through an insulating transfer mechanism, and continuously maintains the negative pressure in the vacuum transfer cabin through a negative pressure pump, which can reduce the gas density in the vacuum transfer cabin and reduce the heat conduction efficiency.

[0007] In addition, the present invention also utilizes a driving motor that drives the transfer vehicle assembly to slide, and automatically controls the opening of the thermal insulation curtain while the transfer vehicle assembly slides, thereby achieving the technical effect that the thermal insulation curtain automatically opens when the transfer vehicle assembly moves (leaving space for the transfer vehicle assembly to pass through) and automatically closes when the transfer vehicle assembly is stationary (isolating heat exchange).

[0008] The technical solution adopted by the present invention is as follows: The present invention proposes an ADI material heat treatment preparation device, including a channel-type dual-track transfer mechanism, a heat-insulating transfer mechanism, a dual-mode drive mechanism, a heating furnace and a salt bath tank, wherein the channel-type dual-track transfer mechanism is arranged at both ends of the heat-insulating transfer mechanism, and the heating furnace and the salt bath tank are connected through the channel-type dual-track transfer mechanism and the heat-insulating transfer mechanism, and the dual-mode drive mechanism includes a rope-type sliding control component, an automatic penetration component, a hydraulic driving component and a driving component, wherein the rope-type sliding control component is arranged inside the salt bath tank, the automatic penetration component is arranged on the heat-insulating transfer mechanism and the salt bath tank, the hydraulic driving component is arranged outside the salt bath tank, and the driving component is arranged outside the salt bath tank;

[0009] Furthermore, the channel-type double-track transfer mechanism includes a reciprocating sliding transfer vehicle assembly, which can be driven to slide by a driving assembly;

[0010] Furthermore, the thermal insulation transfer mechanism includes a vacuum chamber assembly, which includes a vacuum transfer chamber, a negative pressure pump and a thermal insulation curtain. The negative pressure pump is arranged on the vacuum transfer chamber, and the thermal insulation curtain is slidably arranged at both ends of the vacuum transfer chamber.

[0011] The drive motor that drives the transfer vehicle assembly to slide can simultaneously control the opening and closing of the thermal insulation curtain. During the sliding of the transfer vehicle assembly, the thermal insulation curtain is automatically raised to leave space for the passage of the transfer vehicle assembly. After the transfer vehicle assembly stops, the thermal insulation curtain will automatically reset to maintain the negative pressure state in the vacuum chamber assembly and reduce the heat exchange between the heating furnace and the salt bath. By physically isolating the high-temperature zone and the low-temperature zone, it can effectively solve the problems of high heat conduction and serious waste in the traditional monorail system.

[0012] Preferably, the hydraulic propulsion component includes a tail shaft, an impeller, a sliding bracket and a sliding cylinder. The driving component can drive the tail shaft to rotate. The impeller is arranged on the tail shaft. The sliding bracket is arranged on the outside of the salt bath tank. The sliding cylinder is slidably arranged in the sliding bracket. When the sliding cylinder slides, it can slide with the thermal insulation curtain through the automatic through-hole component.

[0013] The sliding cylinder is pushed by the rotation of the impeller, and the automatic through-hole assembly can be driven according to the movement state of the transfer vehicle assembly. After the thermal insulation curtain rises, even if the drive motor continues to rotate, it will not cause damage to the hydraulic propulsion assembly. Unlike the traditional linkage structure, this solution can achieve small-amplitude intermittent driving of the thermal insulation curtain through a drive motor that rotates continuously for a long time.

[0014] As a further preferred embodiment of the present invention, the automatic penetration component includes a steering shaft bracket, a steering wheel and a linkage rope, the steering shaft bracket is respectively arranged on the vacuum transfer cabin and the salt bath tank, the steering wheel is rotatably arranged on the steering shaft bracket, the linkage rope is in rolling contact with the steering wheel, one end of the linkage rope is arranged on the sliding cylinder, and the other end of the linkage rope is arranged on the insulation curtain, and a ring portion is provided on the steering shaft bracket located on the salt bath tank, and the linkage rope passes through the ring portion.

[0015] The end of the linkage pull rope swings with the collar portion as a fulcrum, so no matter which direction the sliding cylinder slides, the same traction effect can be achieved on the linkage pull rope.

[0016] Furthermore, the transfer vehicle assembly includes a transfer slide shaft, a slide plate and a clamping device. The transfer slide shaft is rotatably arranged below the slide plate. The number of the transfer slide shafts is no less than three groups, and the clamping device is arranged on the slide plate.

[0017] Through the reciprocating sliding of the transfer vehicle assembly, the workpiece heated in the heating furnace can be transferred to the salt bath. In the non-transfer stage, the high-temperature insulation channel and the low-temperature insulation channel can be separated by the vacuum chamber assembly. Combined with the negative pressure characteristics of the vacuum transfer chamber, the heat exchange rate in the insulation transfer mechanism can be greatly reduced, thereby achieving the technical effect of solving energy problems.

[0018] Preferably, the channel-type double-track transfer mechanism also includes a low-temperature track and a pulley reset assembly, and the pulley reset assembly includes a spring base 1, a spring base 2 and a reset spring, the spring base 1 is arranged on the slide, the low-temperature track is provided with a low-temperature slide groove, the spring base 2 is arranged on the low-temperature slide groove, and the reset spring is arranged between the spring base 1 and the spring base 2.

[0019] The separate design of high-temperature rails and low-temperature rails avoids the disadvantage of high thermal conductivity efficiency of the overall metal rails. The separate design can also use different materials to manufacture high-temperature rails and low-temperature rails, making them more suitable for their respective working conditions.

[0020] As a further preferred embodiment of the present invention, the rope-type sliding control assembly includes a reel bracket, a rope shaft, a drum and a reset rope, the reel bracket is fixed to the inner wall of the salt bath tank, the rope shaft is rotatably arranged in the reel bracket, the drum is fixed to the rope shaft, one end of the reset rope is wound around the drum, and the other end of the reset rope passes through the spring base two and is fixed to the spring base one.

[0021] Furthermore, the channel-type dual-track transfer mechanism also includes a high-temperature track, which is located between the heating furnace and the vacuum transfer chamber, and the low-temperature track is located between the salt bath and the vacuum transfer chamber. A high-temperature slide is provided on the high-temperature track, and the transfer slide shaft is slidably arranged in the high-temperature slide and the low-temperature slide.

[0022] Furthermore, the thermal insulation transfer mechanism also includes a high-temperature thermal insulation channel and a low-temperature thermal insulation channel. The high-temperature thermal insulation channel is arranged between the heating furnace and the vacuum transfer chamber, and the low-temperature thermal insulation channel is arranged between the salt bath and the vacuum transfer chamber.

[0023] Preferably, the vacuum chamber assembly further includes a negative pressure pump, which is provided on the vacuum transfer chamber and can maintain a negative pressure state in the vacuum transfer chamber through the negative pressure pump.

[0024] As a further preferred embodiment of the present invention, the drive assembly includes a drive motor, a drive gear and a driven gear. The drive motor is arranged on the outer wall of the salt bath tank. The drive gear is fixed to one end of the output shaft of the drive motor. The other end of the output shaft of the drive gear is connected to the tail shaft. The driven gear is fixed to the rope winding shaft, and the drive gear and the driven gear are engaged for transmission.

[0025] The present invention also proposes a method for using the ADI material heat treatment preparation device, which specifically includes the following steps:

[0026] Step 1: After the workpiece is heated in the heating furnace, the drive motor is started. On the one hand, the rope winding shaft rotates through the meshing transmission of the driving gear and the driven gear, and on the other hand, the impeller rotates together through the tail shaft;

[0027] Step 2: When the rope reel rotates, the reset rope is released through the drum. At this time, under the elastic force of the reset spring, the transfer vehicle assembly will slide from the end close to the salt bath tank to the end close to the heating furnace. When the transfer vehicle assembly slides to the gap between the high-temperature chute and the low-temperature chute, since the number of transfer slide shafts is no less than three groups and the spacing between the transfer slide shafts is greater than the spacing between the high-temperature chute and the low-temperature chute, when one transfer slide shaft is located in the gap between the high-temperature chute and the low-temperature chute, the other two transfer slide shafts can still keep the transfer vehicle assembly stable until the transfer vehicle assembly slides to the end close to the heating furnace.

[0028] Step 3: When the tail shaft rotates with the impeller, the impeller will generate thrust on the liquid, thereby pushing the sliding cylinder to slide on the sliding bracket. When the sliding cylinder slides, it will pull the linkage rope, causing the insulation curtain to slide upward, leaving space for the transfer vehicle assembly to pass;

[0029] Step 4: The workpiece is then placed on the slide by an external pickup device and clamped and fixed by a clamping device. At this time, the drive motor is stationary and the impeller is stopped, so the sliding cylinder will slowly reset. When the thermal insulation curtain resets, it will temporarily press the reset spring and the linkage rope. However, since this time is short, it will not have a significant negative impact. Then the drive motor is driven in the reverse direction, and the rope winding shaft and tail shaft rotate in the opposite direction at the same time.

[0030] Step 5: When the rope reel rotates in the reverse direction, the drum will wind up the reset rope, and at the same time overcome the elastic force of the reset spring to pull the transfer vehicle assembly back to the end close to the salt bath tank; when the tail shaft and impeller rotate in the reverse direction, the sliding cylinder will slide in the reverse direction, but the pulling effect on the linkage rope is the same as when sliding in the forward direction, both of which can make the insulation curtain slide upward to leave space for the transfer vehicle assembly to pass through;

[0031] Step 6: After the workpiece is transferred, another external pickup device is used to transfer the workpiece from the clamping device to the lifting platform in the salt bath, and then the workpiece is immersed in the salt solution through the lifting platform.

[0032] The beneficial effects achieved by the present invention using the above structure are as follows:

[0033] (1) Since the transfer channel of the workpiece is isolated from the outside, the transfer time can be effectively shortened and the degree of internal oxidation of the workpiece during the transfer process can be reduced.

[0034] (2) The drive motor that drives the transfer vehicle assembly to slide can simultaneously control the opening and closing of the thermal insulation curtain, so that during the sliding of the transfer vehicle assembly, the thermal insulation curtain is automatically raised to leave space for the transfer vehicle assembly to pass through. After the transfer vehicle assembly stops, the thermal insulation curtain will automatically reset to maintain the negative pressure state in the vacuum chamber assembly and reduce the heat exchange between the heating furnace and the salt bath. By physically isolating the high-temperature zone and the low-temperature zone, it can effectively solve the problem of high heat conduction and serious waste in the traditional monorail system.

[0035] (3) The sliding cylinder is pushed by the rotation of the impeller, and the automatic through-hole assembly can be driven according to the movement state of the transfer vehicle assembly. After the thermal insulation curtain rises, even if the drive motor continues to rotate, it will not cause damage to the hydraulic propulsion assembly. Unlike the traditional linkage structure, this solution can achieve small-amplitude intermittent driving of the thermal insulation curtain by using a drive motor that rotates continuously for a long time.

[0036] (4) The end of the linkage rope swings with the ring as the fulcrum, so no matter which direction the sliding cylinder slides, the same traction effect can be achieved on the linkage rope.

[0037] (5) The workpiece heated in the heating furnace can be transferred to the salt bath tank by the reciprocating sliding of the transfer vehicle assembly. In the non-transfer stage, the high-temperature insulation channel and the low-temperature insulation channel can be separated by the vacuum chamber assembly. Combined with the negative pressure characteristics of the vacuum transfer chamber, the heat exchange rate in the insulation transfer mechanism can be greatly reduced, thereby achieving the technical effect of solving the energy problem.

[0038] (6) The separate design of high-temperature rail and low-temperature rail avoids the disadvantage of high thermal conductivity of the overall metal rail. In addition, the separate design can also use different materials to manufacture high-temperature rail and low-temperature rail, making them more suitable for their respective working conditions.

[0053] The channel-type double-track transfer mechanism 1 includes a reciprocating sliding transfer vehicle assembly 8, which can be driven to slide by a driving assembly 27;

[0054] The thermal insulation transfer mechanism 2 includes a vacuum chamber assembly 20, which includes a vacuum transfer chamber 21, a negative pressure pump 22 and a thermal insulation curtain 23. The negative pressure pump 22 is arranged on the vacuum transfer chamber 21, and the thermal insulation curtain 23 is slidably arranged at both ends of the vacuum transfer chamber 21.

[0055] By using the drive motor 39 that drives the transfer vehicle assembly 8 to slide, the opening and closing of the thermal insulation curtain 23 can be controlled at the same time, so that during the sliding of the transfer vehicle assembly 8, the thermal insulation curtain 23 is automatically raised to leave space for the passage of the transfer vehicle assembly 8. After the transfer vehicle assembly 8 stops, the thermal insulation curtain 23 will automatically reset to maintain the negative pressure state in the vacuum chamber assembly 20 and reduce the heat exchange between the heating furnace 4 and the salt bath tank 5. By physically isolating the high-temperature zone and the low-temperature zone, the problems of high heat conduction and serious waste in the traditional monorail system can be effectively solved.

[0056] The hydraulic propulsion assembly 26 includes a tail shaft 35, an impeller 36, a sliding bracket 37 and a sliding cylinder 38. The driving assembly 27 can drive the tail shaft 35 to rotate. The impeller 36 is arranged on the tail shaft 35. The sliding bracket 37 is arranged on the outside of the salt bath tank 5. The sliding cylinder 38 is slidably arranged in the sliding bracket 37. When the sliding cylinder 38 slides, it can slide with the thermal insulation curtain 23 through the automatic penetration assembly 25.

[0057] The sliding cylinder 38 is pushed by the rotation of the impeller 36, and the automatic penetration component 25 can be driven according to the movement state of the transfer vehicle component 8. After the thermal insulation curtain 23 rises, even if the drive motor 39 continues to rotate, it will not cause damage to the hydraulic propulsion component 26; different from the traditional linkage structure, this solution can achieve small-amplitude intermittent driving of the thermal insulation curtain 23 by the drive motor 39 that rotates continuously for a long time.

[0058] The automatic penetration component 25 includes a steering shaft bracket 32, a steering wheel 33 and a linkage rope 34. The steering shaft bracket 32 ​​is respectively arranged on the vacuum transfer chamber 21 and the salt bath tank 5. The steering wheel 33 is rotatably arranged on the steering shaft bracket 32.

[0059] The end of the linkage pull rope 34 swings with the collar portion 42 as a fulcrum, so no matter which direction the sliding cylinder 38 slides, the same pulling effect can be achieved on the linkage pull rope 34 .

[0060] The transfer vehicle assembly 8 includes a transfer slide shaft 12 , a slide plate 13 and a clamping device 14 . The transfer slide shaft 12 is rotatably arranged below the slide plate 13 . The number of the transfer slide shafts 12 is no less than three groups. The clamping device 14 is arranged on the slide plate 13 .

[0061] Through the reciprocating sliding of the transfer vehicle assembly 8, the workpiece heated in the heating furnace 4 can be transferred to the salt bath 5. In the non-transfer stage, the high-temperature insulation channel 18 and the low-temperature insulation channel 19 can be separated by the vacuum chamber assembly 20. Combined with the negative pressure characteristics of the vacuum transfer chamber 21, the heat exchange rate in the insulation transfer mechanism 2 can be greatly reduced, thereby achieving the technical effect of solving the energy problem.

[0062] The channel-type double-track transfer mechanism 1 also includes a low-temperature track 7 and a pulley reset assembly 9. The pulley reset assembly 9 includes a spring base 15, a spring base 2 16 and a reset spring 17. The spring base 15 is arranged on the slide 13.

The reset spring 17 is arranged between the spring base 15 and the spring base 2 16.

[0063] The separate design of the high-temperature track 6 and the low-temperature track 7 avoids the disadvantage of the high thermal conductivity efficiency of the overall metal track. In addition, the separate design can also use different materials to manufacture the high-temperature track 6 and the low-temperature track 7, making them more suitable for their respective working conditions.

[0064] The rope-type sliding control assembly 24 includes a reel bracket 28, a rope shaft 29, a drum 30 and a reset rope 31. The reel bracket 28 is fixed to the inner wall of the salt bath tank 5, the rope shaft 29 is rotatably arranged in the reel bracket 28, the drum 30 is fixed to the rope shaft 29, one end of the reset rope 31 is wound around the reel 30, and the other end of the reset rope 31 passes through the spring base 2 16 and is fixed to the spring base 1 15.

[0065] The channel-type dual-track transfer mechanism 1 also includes a high-temperature track 6, which is located between the heating furnace 4 and the vacuum transfer chamber 21, and a low-temperature track 7 is located between the salt bath 5 and the vacuum transfer chamber 21. A high-temperature chute 10 is provided on the high-temperature track 6, and the transfer slide shaft 12 is slidably arranged in the high-temperature chute 10 and the low-temperature chute 11.

[0066] The thermal insulation transfer mechanism 2 further includes a high-temperature thermal insulation channel 18 and a low-temperature thermal insulation channel 19 . The high-temperature thermal insulation channel 18 is arranged between the heating furnace 4 and the vacuum transfer chamber 21 , and the low-temperature thermal insulation channel 19 is arranged between the salt bath 5 and the vacuum transfer chamber 21 .

[0067] The vacuum chamber assembly 20 further includes a negative pressure pump 22 , which is disposed on the vacuum transfer chamber 21 . The negative pressure pump 22 can maintain a negative pressure state in the vacuum transfer chamber 21 .

[0068] The drive assembly 27 includes a drive motor 39, a drive gear 40 and a driven gear 41. The drive motor 39 is arranged on the outer wall of the salt bath tank 5. The drive gear 40 is fixedly connected to one end of the output shaft of the drive motor 39. The other end of the output shaft of the drive gear 40 is connected to the tail shaft 35. The driven gear 41 is fixedly connected to the rope winding shaft 29. The drive gear 40 and the driven gear 41 are engaged for transmission.

[0069] The high temperature track 6 can be made of the more heat-resistant Inconel 718 alloy, and the low temperature track 7 can be made of the cheaper 316 stainless steel. The high and low temperatures of the high temperature track 6 and the low temperature track 7 are relative.

[0070] In specific use, after the workpiece is heated in the heating furnace 4, the drive motor 39 is started. On the one hand, the rope winding shaft 29 rotates through the meshing transmission of the driving gear 40 and the driven gear 41, and on the other hand, the impeller 36 rotates together through the tail shaft 35;

[0071] When the rope winding shaft 29 rotates, the reset rope 31 is released by the drum 30. At this time, under the elastic force of the reset spring 17, the transfer vehicle assembly 8 will slide from the end close to the salt bath tank 5 to the end close to the heating furnace 4. When the transfer vehicle assembly 8 slides to the gap between the high-temperature chute 10 and the low-temperature chute 11, since the number of transfer slide shafts 12 is not less than three groups, and the spacing between the transfer slide shafts 12 is greater than the spacing between the high-temperature chute 10 and the low-temperature chute 11, when one transfer slide shaft 12 is located in the gap between the high-temperature chute 10 and the low-temperature chute 11, the other two transfer slide shafts 12 can still keep the transfer vehicle assembly 8 stable until the transfer vehicle assembly 8 slides to the end close to the heating furnace 4;

[0072] When the tail shaft 35 rotates with the impeller 36, the impeller 36 generates thrust on the liquid, thereby pushing the sliding cylinder 38 to slide on the sliding bracket 37. When the sliding cylinder 38 slides, it pulls the linkage pull rope 34, thereby sliding the thermal insulation curtain 23 upward, leaving space for the transfer vehicle assembly 8 to pass through;

[0073] The workpiece is then placed on the slide 13 by an external pickup device and clamped and fixed by the clamping device 14. At this time, the drive motor 39 is stationary and the impeller 36 has stopped rotating, so the sliding cylinder 38 will slowly reset. When the thermal insulation curtain 23 resets, it will temporarily press the reset spring 17 and the linkage pull rope 34. However, since this time is short, it will not have a significant negative impact. The drive motor 39 is then driven in the reverse direction, causing the rope winding shaft 29 and the tail shaft 35 to rotate in the opposite direction.

[0074] When the rope winding shaft 29 rotates in the reverse direction, the drum 30 will wind and reel the reset rope 31, and at the same time overcome the elastic force of the reset spring 17 to pull the transfer vehicle assembly 8 back to the end close to the salt bath tank 5; when the tail shaft 35 and the impeller 36 rotate in the reverse direction, the sliding cylinder 38 will slide in the reverse direction, but the pulling effect on the linkage rope 34 is the same as when sliding in the forward direction, and both can make the insulation curtain 23 slide upward to leave space for the transfer vehicle assembly 8 to pass through;

[0075] After the workpiece is transferred, another external picking device is used to transfer the workpiece from the clamping device 14 to the lifting platform in the salt bath tank 5, and then the workpiece is immersed in the salt solution through the lifting platform.

9. A method for using an ADI material heat treatment preparation device, applicable to the ADI material heat treatment preparation device according to claim 8, characterized in that: The method comprises the following steps: Step 1: After the workpiece is heated in the heating furnace (4), the driving motor (39) is started. On the one hand, the driving motor (40) and the driven gear (41) are meshed to drive the rope winding shaft (29) to rotate, and on the other hand, the tail shaft (35) and the impeller (36) are rotated together. Step 2: When the rope reel (29) rotates, the reel (30) releases the reset rope (31). At this time, under the elastic force of the reset spring (17), the transfer vehicle assembly (8) slides from the end close to the salt bath tank (5) toward the end close to the heating furnace (4). When the transfer vehicle assembly (8) slides to the gap between the high-temperature chute (10) and the low-temperature chute (11), since the number of transfer slide shafts (12) is not less than three groups, and the spacing of the transfer slide shafts (12) is greater than the spacing between the high-temperature chute (10) and the low-temperature chute (11), when one transfer slide shaft (12) is located in the gap between the high-temperature chute (10) and the low-temperature chute (11), the other two transfer slide shafts (12) can still keep the transfer vehicle assembly (8) stable until the transfer vehicle assembly (8) slides to the end close to the heating furnace (4); Step 3: When the tail shaft (35) rotates with the impeller (36), the impeller (36) generates thrust on the liquid, thereby pushing the sliding cylinder (38) to slide on the sliding bracket (37). When the sliding cylinder (38) slides, it pulls the linkage rope (34), thereby causing the insulation curtain (23) to slide upward, leaving space for the transfer vehicle assembly (8) to pass; Step 4: The workpiece is then placed on the slide (13) by an external pickup device and clamped and fixed by the clamping device (14). At this time, the drive motor (39) is stationary and the impeller (36) stops rotating, so the sliding cylinder (38) will slowly reset. When the heat insulation curtain (23) resets, it will temporarily press the reset spring (17) and the linkage pull rope (34). However, since this time is short, it will not produce obvious negative effects. Then, the drive motor (39) is driven in the reverse direction, and the rope winding shaft (29) and the tail shaft (35) are rotated in the reverse direction. Step 5: When the rope reel (29) rotates in the reverse direction, the reel (30) will wind and reel the reset rope (31), and at the same time overcome the elastic force of the reset spring (17) to pull the transfer vehicle assembly (8) back to the end close to the salt bath tank (5); when the tail shaft (35) and the impeller (36) rotate in the reverse direction, the sliding cylinder (38) will slide in the reverse direction, but the pulling effect on the linkage rope (34) is the same as when sliding in the forward direction, and both can make the insulation curtain (23) slide upward to leave space for the transfer vehicle assembly (8) to pass through; Step 6: After the workpiece is transferred, another external picking device is used to transfer the workpiece from the clamping device (14) to the lifting platform in the salt bath tank (5), and then the workpiece is immersed in the salt solution through the lifting platform.
