Technical Field

[0001] The utility model relates to the technical field of pick production, in particular to a pick heat treatment material rack. Background Technique

[0002] There are many types of picks. Generally, the structure is to inlay a hard alloy cutter head on a low alloy structural steel cutter body that has been quenched and tempered. When the pick is working, it bears high cyclic compressive stress, shear stress, and impact load. The main failure forms are cutter head shedding, cutter breakage, and wear of the cutter head and cutter body. Under certain working conditions, the pick often fails due to cutter body breakage. Since the mechanical properties of the pick cutter body directly affect the service life of the pick, it is of positive significance to reasonably select the material of the pick cutter body and an effective heat treatment method to reduce the wear and breakage of the pick cutter body, reduce the consumption of shearer picks, improve the operation rate of coal mining machinery, and increase the comprehensive economic benefits of coal mining production. Due to production needs, a special material rack for pick heat treatment came into being;

[0003] Most of the existing pick heat treatment material racks are put into the heat treatment furnace by a hoisting mechanism, but they cannot be moved inside the furnace. When they are heat-treated, they cannot be heated evenly, which will lead to uneven product quality. Content of the Utility Model

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a pick heat treatment material rack, which can solve the problems in the background technique. [[ID=1�]]

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a pick heat treatment material rack, including a furnace body, a box door is arranged on the front side of the furnace body, a strengthening leg is fixedly connected to the lower end of the furnace body, a driving motor is fixedly connected to one side of the furnace body, two sliding grooves are opened on the inner bottom surface of the furnace body, a U-shaped support frame is arranged inside the furnace body, a placing rack is arranged inside the support frame, and a rotating mechanism is arranged on the support frame.

[0006] Preferably, the rotating mechanism includes two rotating shafts, the two rotating shafts are respectively rotatably connected inside the support frame, rotating discs are respectively fixedly connected to the opposite ends of the two rotating shafts, positioning shafts are respectively fixedly connected to the opposite sides of the rotating discs, and connecting plates are rotatably connected to the positioning shafts, and the placing rack is fixedly connected to the connecting plates.

[0007] Preferably, one of the rotating shafts extends out of the support frame, a second gear is fixedly sleeved on the rotating shaft extending out of the support frame, a first gear is fixedly connected to the output end of the driving motor, and the second gear is meshed with the first gear.

[0008] Preferably, the bottom of the support frame is hollow, and both sides of the support frame are hollowed out.

[0009] Preferably, two sliders are fixedly connected to the bottom of the support frame, and the two sliders are slidably connected to the inside of the slide groove respectively, and two positioning blocks are fixedly connected to one side of the box door close to the inside of the furnace body.

[0010] Preferably, the ends of the two positioning blocks that do not contact the door are arc-shaped.

[0011] Preferably, a visual window is embedded in the door.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) The pick heat treatment material rack, when the picks are placed, the support rack is pushed into the interior of the furnace body through the slider. At this time, as the support rack moves, the second gear is meshed and connected with the first gear. At this time, the box door is closed, and the positioning block on the box door fixes the support rack and the slider. At this time, the drive motor is started, and the output end of the drive motor drives the first gear to rotate. Due to the principle of meshing transmission, the second gear rotates at the same time, and then the second gear drives the rotating disk to rotate at the same time through the rotating shaft. Since the placement rack is connected to the positioning shaft through the connecting plate, the placement rack is always in a vertical state with its own weight and the weight of the pick. Then, as the rotating disk continues to rotate, the position of the placement rack changes continuously, so that the pick is heated more evenly, so that it is not in a static state during the process inside the furnace body, thereby ensuring the effect of heat treatment.

[0014] (2) The pick heat treatment material rack is provided with a positioning block. Therefore, when the box door is closed, the positioning block enters the interior of the slide groove to support the slider, thereby fixing the slider and the support frame inside the furnace body, thereby avoiding the shaking phenomenon and ensuring the stability of the pick heat treatment process.

Detailed implementation manners

[0022] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it should not be construed as a limitation on the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 , the present utility model provides a technical solution: a pick heat treatment material rack, including a furnace body 1, a box door 2 is arranged on the front side of the furnace body 1, a strengthening leg 15 is fixedly connected to the lower end of the furnace body 1, a drive motor 4 is fixedly connected to one side of the furnace body 1, two sliding grooves 8 are opened on the inner bottom surface of the furnace body 1, a U-shaped support frame 5 is arranged inside the furnace body 1, the bottom of the support frame 5 is hollow, both sides of the support frame 5 are hollowed out, a placing rack 7 is arranged inside the support frame 5, and a rotating mechanism is arranged on the support frame 5;

[0024] When heat treatment of the pick is required, the support frame 5 can be pulled out from the inside of the furnace body 1. At this time, the pick to be processed is placed on the placing rack 7, and the support frame 5 is pushed back into the furnace body 1 again, and the box door 2 is closed to seal the furnace body 1. At this time, the heating function of the furnace body 1 is started, and under the drive of the rotating mechanism, the pick can be heated evenly.

[0025] Further, a viewing window 3 is inlaid on the box door 2;

[0026] By providing the viewing window 3, when the furnace body 1 is closed, the operator can observe the working state of the furnace body 1 and the state of the pick heat treatment through the viewing window 3, so it is convenient for the operator to judge the pick heat treatment situation.

[0027] Further, two sliders 10 are fixedly connected to the bottom of the support frame 5, the two sliders 10 are respectively slidably connected inside the sliding grooves 8, and two positioning blocks 9 are fixedly connected to the side of the box door 2 close to the inside of the furnace body 1;

[0028] By fixedly connecting the slider 10 to the support frame 5 and slidingly connecting to the slide groove 8, the support frame 5 can be more easily slid in and out of the furnace body 1, thereby making it more convenient to enter the furnace body 1 during the heat treatment process and to take it out after the treatment is completed, and the operator no longer needs to reach into the furnace body 1 to take and place the pick, thereby reducing the risk of burns;

[0029] And through the provision of the positioning block 9, when the box door 2 is closed, the positioning block 9 enters the interior of the slide groove 8 to support the slider 10, thereby fixing the slider 10 and the support frame 5 inside the furnace body 1, thereby avoiding any shaking, thereby ensuring the stability of the pick during the heat treatment process.

[0030] Furthermore, the ends of the two positioning blocks 9 that do not contact the door 2 are arc-shaped;

[0031] By setting one end of the positioning block 9 to be arc-shaped, it will no longer get stuck inside the slide groove 8, thereby ensuring that the positioning block 9 can normally enter the interior of the slide groove 8 and ensure the normal opening and closing of the door 2.

[0032] Furthermore, the rotating mechanism includes two rotating shafts 13, which are rotatably connected to the interior of the support frame 5. The two rotating shafts 13 are fixedly connected to the rotating disk 6 on opposite ends, and the positioning shafts 11 are fixedly connected to the opposite sides of the rotating disk 6. The positioning shafts 11 are rotatably connected to the connecting plates 12, and the display frame 7 is fixedly connected to the connecting plates 12.

[0033] One of the rotating shafts 13 extends out of the support frame 5, and a second gear 16 is fixedly sleeved on the rotating shaft 13 extending out of the support frame 5. The output end of the driving motor 4 is fixedly connected to the first gear 14, and the second gear 16 is meshed with the first gear 14;

[0034] After the pick is placed, the support frame 5 is pushed into the interior of the furnace body 1 by the slider 10. At this time, as the support frame 5 moves, the second gear 16 is meshed with the first gear 14. At this time, the box door 2 is closed, and the positioning block 9 on the box door 2 fixes the support frame 5 and the slider 10. At this time, the driving motor 4 is started, and the output end of the driving motor 4 drives the first gear 14 to rotate. Due to the principle of meshing transmission, the second gear 16 rotates at the same time, and then the second gear 16 drives the rotating disk 6 to rotate at the same time through the rotating shaft 13. Since the placing frame 7 is rotatably connected to the positioning shaft 11 through the connecting plate 12, the placing frame 7 is always in a vertical state following its own weight and the weight of the pick, and then with the continuous rotation of the rotating disk 6, the position of the placing frame 7 is constantly changing, so that the pick is heated more evenly, so that it is not in a static state during the process inside the furnace body 1, thereby ensuring the effect of heat treatment.

[0035] Among them, multiple placement racks 7 can be provided, and the multiple placement racks 7 are all arranged between the rotating disks 6 through the positioning shafts 11 and the connecting plates 12.

[0036] Working principle: After the pick is placed, the support frame 5 is pushed into the interior of the furnace body 1 through the slider 10. At this time, as the support frame 5 moves, the second gear 16 is meshed and connected with the first gear 14. Then the box door 2 is closed, and the positioning block 9 on the box door 2 fixes the support frame 5 and the slider 10. At this time, the driving motor 4 is started, and the output end of the driving motor 4 drives the first gear 14 to rotate. Due to the principle of meshing transmission, the second gear 16 rotates simultaneously. Furthermore, the second gear 16 drives the rotating disk 6 to rotate simultaneously through the rotating shaft 13. Since the placement rack 7 is rotationally connected with the positioning shaft 11 through the connecting plate 12, the placement rack 7 always remains in a vertical state due to its own weight and the weight of the pick. Furthermore, as the rotating disk 6 rotates continuously, the position of the placement rack 7 changes continuously. Therefore, the pick is heated more evenly.

[0037] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the technical field, various changes can be made without departing from the purpose of the present invention.
