Description

Technical Field

[0001] The invention relates to the technical field of quenching production, in particular to a high-efficiency conveying device for tempering heat treatment of chain track segments. Background Art

[0002] Crawler-type walking mechanisms are widely used in construction machinery, most of which work in harsh environments such as mining development and construction excavation. Therefore, there are strict requirements for the components that make up them. The most important component of the crawler is the track link, which plays a vital role in the normal operation of the crawler-type walking mechanism. The most important process in processing the track link is the tempering treatment, which can increase the mechanical properties of the track link, such as tensile strength and yield strength.

[0003] The current method for quenching and tempering track segments is to heat them uniformly in a quenching furnace, then cool them in a quenching liquid, and then use a forklift to fork the hot and cold track segments into a box-type tempering furnace for tempering. This process is complicated and inefficient, and the quality of the track segment quenching and tempering cannot be guaranteed. At the same time, the current quenching of track segments usually involves directly placing the workpiece in the quenching liquid. The workpiece cooling rate is too high, and the microstructure stress in the martensitic transformation zone of the workpiece increases sharply when it is below 300°C. In particular, when carbon steel is quenched in water, once the cooling rate exceeds 200°C / s, quenching cracking is likely to occur.

[0004] Therefore, how to provide an efficient conveying device for the tempering heat treatment of chain track segments is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] One purpose of the present invention is to propose an efficient conveying device for tempering heat treatment of chain track segments.

[0006] According to an embodiment of the present invention, a high-efficiency conveying device for tempering heat treatment of a chain rail segment includes a calcining furnace and a quenching assembly. The quenching assembly is connected to the discharge port of the calcining furnace. A lifting mechanism is provided between the quenching assembly and the calcining furnace. The quenching assembly is connected to the tempering port of the calcining furnace through a drop hopper. The quenching assembly includes a pool body, a partition plate and a drop bin.

The drop hopper is fixed to the top of the protective plate near the tempering port of the calcining furnace.

[0008] There are five sets of lifting plates opposite to each other in the blanking bin, which swing back and forth up and down in the blanking bin under the control of the reciprocating mechanism;

[0009] A liquid bin assembly is provided below the drop bin. The reciprocating mechanism drives the lifting plate to swing up and down, and at the same time, the quenching liquid in the liquid bin assembly can be transported to the top of the drop bin for spraying through the liquid supply mechanism.

[0010] Furthermore, a conveying mechanism is provided between two adjacent groups of pool plates, and the conveying mechanism includes an interlocking roller and several groups of fin rollers. The several groups of fin rollers overlap with each other, and the fin rollers are distributed at a certain oblique angle in the pool plate. One end of the fin roller is sealed and passes through the pool body and is fixed with a toothed wheel. Several groups of toothed wheels are externally sleeved with a single group of toothed belts, and corresponding limiting grooves are provided on the surface of the pool body near the toothed belts for limiting the toothed belts.

[0011] Furthermore, the interlocking roller passes through the partition plate and is fixed at one end of the single set of fin rollers. The interlocking roller is located directly below the herringbone chain mesh belt and interlocks with the surface of the herringbone chain mesh belt.

[0012] Furthermore, a loading mechanism is provided inside the pool body near the end of the partition plate. The loading mechanism includes an executing electric cylinder, a push plate and a support platform. The executing electric cylinder is fixed on the outside of the pool body. The output end of the executing electric cylinder passes through the pool body and is fixed on the push plate. The push plate moves horizontally on the support platform. The support platform is fixed inside the pool body, and one end of the support platform is aligned with the surface of the herringbone chain mesh belt.

[0013] Furthermore, a feeding port is opened at the top of the pool body near the herringbone chain mesh belt, and a hopper opening is opened above the drop hopper on the side close to the calcining furnace. The hopper opening is aligned with the calcining furnace discharge port and is located directly above the single set of lifting plates.

[0014] Furthermore, the reciprocating mechanism includes an executive motor and a frame-type slide. The executive motor is fixed on the top of the blanking bin. The output shaft of the executive motor is fixed to the crank shaft. The crank shaft slides in a sliding pin groove opened above the frame-type slide. Five groups of meshing grooves are opened in staggered directions on the surface of the frame-type slide. A single group of meshing grooves corresponds to the meshing wheel on the rotating shaft of a single group of lifting plates. The bottom of the lifting plate is elastically connected to the inner wall of the blanking bin through a tension spring.

[0015] Furthermore, the bottom of the frame-shaped slide slides through the feeding port and is fixed to the top of the pushing plate, and the liquid extraction pipe is connected to the inside of the liquid bin assembly just below the pushing plate.

[0016] Furthermore, the liquid tank assembly includes a liquid storage tank and a partition plate. A one-way valve tube is provided on the surface of the partition plate.

[0017] Furthermore, the liquid supply mechanism includes a temperature control component, a liquid supply pipe and a liquid extraction pipe. The temperature control component is connected to the atomizer through the liquid supply pipe. The atomizer is fixed on the top of the inner surface of the drop bin. The temperature control component is connected to the liquid bin component through the liquid extraction pipe.

[0018] The beneficial effects of the present invention are:

[0019] The present invention provides a lifting mechanism between the quenching assembly and the calcining furnace. After the driving motor is started, it can drive the herringbone chain mesh belt to operate inside the tank body through the transmission roller segment, drive the chain rail segment to transport the workpiece from the tank body to the tempering port of the calcining furnace connected to the drop hopper, and use the herringbone chain mesh belt to connect the quenching and tempering processes of the workpiece, so that the quenching and tempering processes can operate continuously. Compared with the existing technology, it not only improves production efficiency, but also saves equipment installation space by utilizing the height difference between the upper and lower ends of the lifting mechanism.

[0020] The present invention is provided with a reciprocating mechanism. After the execution motor is started, on the one hand, it can drive the lifting plate to swing back and forth inside the blanking bin, so that the chain track segment stays in the blanking bin for a longer time for pre-cooling. At the same time, the reciprocating mechanism can synchronously transport the high-temperature quenching liquid in the liquid bin assembly to the atomizer through the liquid supply mechanism for atomization, so that it becomes a high-temperature steam state, and assists the lifting plate in supporting and realizing the pre-cooling operation of the chain track segment, so that it can achieve a slow cooling operation before quenching, thereby preventing quenching cracking during subsequent quenching.

[0021] The present invention sets several groups of pool plates and feeding ports. When the herringbone chain mesh belt drives the chain track segment to automatically lift and temper, the herringbone chain mesh belt can engage the interlocking roller, and the interlocking roller drives a single group of fin rollers and a toothed wheel to rotate. Under the transmission of the toothed belt, several groups of fin rollers rotate synchronously in the same direction, so as to push the chain track segment to be quenched in the pool plate and transported to the next level of pool plate, so that the quenching operation is modularized and graded to ensure the quenching quality. At the same time, different pool plates form different temperature zones, so that the actual control effect of the quenching temperature is stronger, and the occurrence of quenching cracks is further prevented.

[0022] The present invention is provided with an atomizer, which can not only atomize the high-temperature quenching liquid and form a mist layer in the blanking bin to pre-cool the chain track segment, but also the high-temperature mist will flow outward along the channel between the partition plate and the pool body, which can better isolate the entry of air, so that when the conveying mechanism drives the chain track segment to enter the next-level partition plate, the chain track segment will not come into contact with the air, thereby preventing oxidation from occurring, and effectively ensuring the quenching quality of the quenching process.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0036] refer to Figures 1-8 , comprising a calcining furnace 1 and a quenching assembly 2, characterized in that the quenching assembly 2 is docked with the discharge port of the calcining furnace 1, a lifting mechanism 3 is provided between the quenching assembly 2 and the calcining furnace 1, the quenching assembly 2 is docked with the tempering port of the calcining furnace 1 through a drop hopper 35, the quenching assembly 2 comprises a pool body 21, a partition plate 22 and a drop bin 23, the partition plate 22 is fixed inside the pool body 21, a plurality of groups of pool plates 24 are fixed between the left bottom of the partition plate 22 and the inner wall of the pool body 21, the drop bin 23 is fixedly arranged just above the side of the pool body 21 close to the calcining furnace 1, and the drop bin 23 is communicated with the partition plate 22;

[0037] The lifting mechanism 3 includes a protective plate 31, a herringbone chain mesh belt 32, a drive motor 33 and a transmission roller section 34. Several groups of transmission roller sections 34 are rotatably arranged on the inner side of the protective plate 31 and inside the tank body 21. The protective plate 31 is engaged and sleeved on the surface of the transmission roller section 34. A single group of transmission roller sections 34 is driven to rotate by the output shaft of the drive motor 33. The drive motor 33 is fixed to the outside of the tank body 21. The herringbone chain mesh belt 32 moves to transfer the chain rail sections inside the tank body 21 to the port of the drop hopper 35. The drop hopper 35 is fixed to the top of the protective plate 31 at one end near the tempering port of the calcining furnace 1.

[0038] Five sets of lifting plates 6 are arranged opposite to each other in the blanking bin 23. The five sets of lifting plates 6 are controlled by the reciprocating mechanism 7 to swing back and forth in the blanking bin 23.

[0039] A liquid bin assembly 26 is provided below the drop bin 23 , and the reciprocating mechanism 7 drives the lifting plate 6 to swing up and down, and simultaneously can deliver the quenching liquid in the liquid bin assembly 26 to the top of the drop bin 23 for spraying through the liquid supply mechanism 4 .

[0040] In this embodiment, a lifting mechanism 3 is provided between the quenching assembly 2 and the calcining furnace 1. After the lifting mechanism 3 is in operation, it can drive and lift the chain rail segment that has completed quenching to the inlet position of the calcining furnace 1 again, so as to achieve the effect of cyclic calcination and quenching, and a partition plate 22 is provided inside the pool body 21. The existence of the partition plate 22 divides the inside of the pool body 21 into two areas, one side is used for the circulation operation of the herringbone chain mesh belt 32, and the other side is used for actual quenching. After the chain rail segment that has completed calcination inside the calcining furnace 1 enters the discharge bin 23, under the effect of the support of the lifting plate 6 and the reciprocating mechanism 7 driving the lifting plate 6 to swing back and forth, the chain rail segment slides from the single group of lifting plates 6 to the other group of lifting plates 6 below, thereby reducing the chain rail segment. The falling speed of the section in the blanking bin 23 is controlled to realize the first-level pre-cooling operation. At the same time, the reciprocating mechanism 7 can push the liquid inside the liquid bin assembly 26, and realize the atomization operation of the high-temperature quenching liquid in the blanking bin 23 through the liquid supply mechanism 4. The synchronous lifting plate 6 is used to realize the second-level pre-cooling operation to prevent the chain track section from being too hot and encountering the quenching liquid, which causes quenching cracking due to rapid cooling. The chain track section is actually quenched after falling from the lowest lifting plate 6 into the sub-pool plate 24. The establishment of several groups of sub-pool plates 24 makes the quenching liquid temperature between adjacent different sub-pool plates 24 different, realizing modular quenching effect, further controlling the temperature reduction speed, and finally being conveyed by the lifting mechanism 3 to the inside of the calcining furnace 1 for re-calcining operation.

[0041] refer to Figure 2 、 Figure 3 、 Figure 5 and Figure 6 A conveying mechanism 5 is provided between two adjacent groups of partition plates 24. The conveying mechanism 5 comprises an interlocking roller 51 and several groups of fin rollers 52. The groups of fin rollers 52 overlap each other and are arranged at a certain angle within the partition plate 24. One end of the fin roller 52 is sealed and extends through the tank body 21 and is fixed with a toothed wheel 53. The groups of toothed wheels 53 are externally sleeved with a single set of toothed belts 54. Corresponding limiting grooves are provided on the surface of the tank body 21 near the toothed belt 54 to limit the position of the toothed belt 54. The interlocking roller 51 extends through the partition plate 22 and is fixed to one end of the single set of fin rollers 52. The interlocking roller 51 is located directly below the herringbone chain mesh belt 32 and interlocks with the surface of the herringbone chain mesh belt 32.

[0042] In this embodiment, a conveying mechanism 5 is respectively provided in the area formed by each adjacent sub-pool plate 24. After the chain track segment enters the quenching pool formed by the first sub-pool plate 24, it will fall on the surface of the fin roller 52, and one end of the fin roller 52 is connected to the bite roller 51. At this time, the operation of the herringbone chain mesh belt 32 will drive the bite roller 51 to rotate under the bite effect. After the fin roller 52 rotates, the other end bites with the toothed belt 54 through the toothed wheel 53, so that several groups of fin rollers 52 can all rotate in the same direction and at the same speed, so that the chain track segment on the surface is driven out of the quenching pool and falls into the quenching pool of the next level. In this way, the temperature zones of the quenching liquid in different quenching pools are different, so as to achieve better quenching. Operation, to prevent the quenching liquid temperature from being too low, which may cause the chain track segment to crack during quenching. At the same time, it is worth noting that the fin rollers 52 and the fin rollers 52 overlap with each other. The overlap here means that the fin rollers 52 themselves are fin-shaped, but in fact they are fins with a thicker thickness. The fins are inserted into each other to increase the contact area of ​​the bottom of the chain track segment and reserve space for the liquid to enter. In this way, the bottom of the chain track segment can also fully contact with the quenching liquid to prevent the quenching liquid and the chain track segment from having insufficient contact. At the same time, the uppermost fin roller 52 is above the quenching liquid and is aligned with the quenching pool formed by the next-level sub-pool plate 24. In the rolling state, the chain track segment falls into the next-level quenching pool to achieve quenching.

[0043] In order to prevent slipping between the toothed wheel 53 and the toothed belt 54 / between the bite roller 51 and the herringbone chain mesh belt 32, during actual use, it is necessary to open a limiting groove on the surface of the pool body 21 to limit the movement trajectory of the toothed belt 54 and the herringbone chain mesh belt 32 to prevent them from slipping and detaching.

[0044] refer to Figure 2-Figure 4 A feeding mechanism 8 is provided inside the pool body 21 near the end of the partition plate 22. The feeding mechanism 8 includes an executing electric cylinder 81, a push plate 82 and a support platform 83. The executing electric cylinder 81 is fixed on the outside of the pool body 21. The output end of the executing electric cylinder 81 passes through the pool body 21 and is fixed on the push plate 82. The push plate 82 moves horizontally on the support platform 83. The support platform 83 is fixed inside the pool body 21. One end of the support platform 83 is aligned with the surface of the herringbone chain mesh belt 32.

[0045] In this embodiment, the end position of the partition plate 22 refers to the position connecting the left and right areas of the partition plate 22. Here, the fin roller 52 transports the quenched chain rail segment to the surface of the support platform 83, and one end of the push plate 82 is aligned with the top of the herringbone chain mesh belt 32. After the execution electric cylinder 81 is started, the output end of the execution electric cylinder 81 will drive the push plate 82 to push the chain rail segment on the surface of the support platform 83, so that it falls on the surface of the herringbone chain mesh belt 32, and finally the herringbone chain mesh belt 32 in the running state is transported to the position of the drop hopper 35 to realize the tempering operation.

[0046] refer to Figure 2A feeding port 25 is opened at the top of the pool body 21 near the herringbone chain mesh belt 32, and a silo opening 27 is opened on the side above the discharge silo 23 near the calcining furnace 1. The silo opening 27 is aligned with the discharge port of the calcining furnace 1, and the silo opening 27 is located directly above the single set of lifting plates 6.

[0047] In this embodiment, the opening of the feeding port 25 provides the herringbone chain mesh belt 32 with sufficient space to transport the chain rail segments. In addition, it is better to set a suction fan at this position to suck out the toxic and harmful gases and mist generated inside the quenching component 2 to ensure the actual working environment. The opening position of the hopper port 27 is aligned with the discharge port of the calcining furnace 1. After the chain rail segments calcined in the calcining furnace 1 fall into the drop bin 23, they need to be lifted by the top lifting plate 6. Therefore, the opening position of the hopper port 27 needs to be close to the side above the lifting plate 6.

[0048] refer to Figure 3 、 Figure 5 and Figure 7 The reciprocating mechanism 7 includes an actuator motor 71 and a frame-shaped carriage 73. The actuator motor 71 is fixed to the top of the blanking bin 23. The output shaft of the actuator motor 71 is fixed to a crankshaft 72. The crankshaft 72 slides within a sliding pin slot 74 provided above the frame-shaped carriage 73. Five sets of engaging slots 75 are staggered on the surface of the frame-shaped carriage 73. Each set of engaging slots 75 engages with an engaging wheel 76 on the rotating shaft of a single set of lifting plates 6. The bottom of the lifting plates 6 is elastically connected to the inner wall of the blanking bin 23 via a tension spring 77. The bottom of the frame-shaped carriage 73 slides through the feed port 25 and is fixed to the top of the pushing plate 78. The liquid extraction pipe 44 is connected to the interior of the liquid bin assembly 26, just below the pushing plate 78.

[0049] After the cam 73 is in the process of being moved, the cam 73 is moved back and forth, and ...

[0050] refer to Figure 3 、 Figure 5 and Figure 8The liquid tank assembly 26 includes a liquid storage tank 261 and a partition plate 262. A one-way valve tube 263 is provided on the surface of the partition plate 262. A valve ball 264 is movably provided inside the one-way valve tube 263. A filter screen plate 265 is provided at one end of the liquid storage tank 261 close to the partition plate 24.

[0051] In this embodiment, a first-level quenching pool is formed between the liquid storage tank 261 and the single-component pool plate 24. The quenching liquid here has the highest temperature because it contacts the chain track segment earliest. A filter screen plate 265 is provided on one side of the liquid storage tank 261 to filter out quenching impurities in the quenching liquid. Pure high-temperature quenching liquid normally enters the space area on the other side of the partition plate 262 through the one-way valve tube 263 on the surface of the partition plate 262. The frame-type slide 73 will also drive the pushing plate 78 to move up and down in this position area during the reciprocating up and down movement process, pushing the quenching liquid into the temperature control component 41 through the liquid extraction pipe 44. At this time, under the action of liquid pressure, the valve ball 264 will be tightly attached to the surface of the one-way valve tube 263 to prevent backflow.

[0052] refer to Figure 3-Figure 5 The liquid supply mechanism 4 includes a temperature control component 41, a liquid supply pipe 42 and a liquid extraction pipe 44. The temperature control component 41 is connected to the atomizer 43 through the liquid supply pipe 42. The atomizer 43 is fixed on the top of the inner surface of the blanking bin 23. The temperature control component 41 is connected to the liquid bin component 26 through the liquid extraction pipe 44.

[0053] In this embodiment, after the quenching liquid enters the temperature control component 41 through the liquid extraction pipe 44, the temperature is further controlled by the temperature control component 41 to prevent the temperature from being too high or too low, and then transported to the atomizer 43 on the top of the blanking bin 23 through the liquid supply pipe 42. At this time, the atomizer 43 realizes the spraying of quenching liquid, thereby realizing a mist layer inside the blanking bin 23. The mist layer carries a certain temperature. After it contacts the surface of the chain rail segment, it can cooperate with the slow drop of the lifting plate 6 to realize a secondary pre-cooling scheme, thereby preventing the chain rail segment from having too high a temperature and then rapidly cooling down after entering the quenching liquid, resulting in quenching cracking of the chain rail segment.

[0054] Working principle: First, the calcining furnace 1 calcines the chain rail segments. The calcined chain rail segments enter the drop bin 23 from the hopper opening 27 opened at the top of the drop bin 23. The chain rail segments normally fall on the surface of the lifting plate 6. The execution motor 71 drives the crank shaft 72 to rotate. Due to the influence of the sliding pin groove 74 opened at the top of the frame slide 73 and the rotation effect of the crank shaft 72, the frame slide 73 as a whole moves back and forth inside the drop bin 23. The moving effect is normally engaged with the meshing groove 75 of the lifting plate 6 shaft. The closing wheel 76 causes the lifting plate 6 to swing back and forth, and the chain track segment slowly falls inside the drop bin 23. During this process, the frame slide 73 also squeezes the quenching liquid inside the liquid bin assembly 26 through the pushing plate 78. Under the effect of the valve ball 264 closing the one-way valve tube 263, the quenching liquid enters the temperature control assembly 41 from the liquid extraction pipe 44, and is then supplied to the atomizer 43 on the top of the drop bin 23 through the liquid supply pipe 42 to achieve atomization. The atomized high-temperature quenching mist contacts the surface of the chain track segment, achieving a secondary pre-quenching. The chain rail section then falls from the surface of the bottom lifting plate 6 into the quenching pool composed of the liquid storage tank 261 and the sub-pool plate 24 to achieve quenching. The driving motor 33 drives the transmission roller section 34 to operate, and the herringbone chain mesh belt 32 on the inner side of the protective plate 31 is forced to move. The bite effect causes the bite roller 51 to rotate in the pool body 21. At this time, the fin roller 52 at one end of the bite roller 51 is forced to rotate. Under the bite action of the toothed wheel 53 and the toothed belt 54, several groups of fin rollers 52 rotate synchronously, driving the quenching The chain rail segment in the fire pool enters the next level quenching pool composed of two adjacent groups of pool plates 24 for quenching. Finally, after multi-stage quenching and cooling, the chain rail segment falls on the surface of the support platform 83. The execution electric cylinder 81 is started and the chain rail segment on the surface of the support platform 83 is pushed by the push plate 82 to fall on the herringbone chain mesh belt 32. At this time, the herringbone chain mesh belt 32 drives the chain rail segment to continuously lift from the feeding port 25 to the position of the drop hopper 35, and under the guidance of the drop hopper 35, it falls into the interior of the calcining furnace 1 to complete the cyclic calcination and quenching operation.
