Description

Technical Field

[0001] This invention relates to the field of gear processing technology, and more specifically, to a waste heat recovery heat treatment device for gear processing. Background Technology

[0002] After the gear teeth are machined, they need to be further heat-treated to give the gear good comprehensive mechanical properties, improve the toughness and strength of the core, and improve the hardness and wear resistance of the tooth surface to adapt to complex working conditions. Increasing the carbon content of the tooth surface increases the surface hardness and wear resistance to meet the performance requirements of hard surface and tough core of the gear, thereby improving the load-bearing capacity and service life of the gear.

[0003] Chinese patent application number CN202111370438.5 relates to the technical field of gear processing, and in particular to a waste heat recovery heat treatment device and gear processing technology for gear processing. The main device is a waste heat recovery heat treatment device for gear processing, which includes a furnace body. The outer side of the furnace body is wrapped with a waste heat recovery structure. The waste heat recovery structure includes an outer shell sleeved on the outer side of the furnace body and a heat exchange tube disposed between the inner wall of the outer shell and the outer wall of the furnace body. The outer shell contains a heat-conducting medium.

[0004] The above technical solution allows for the storage and utilization of heated water, or the use of this hot water for subsequent cleaning needs, enabling the recovery and utilization of heat energy and saving energy. However, the furnace body in the solution is cylindrical. While it can achieve uniform heating of a typical circular gear, gears in real life are diverse. When heating a bevel gear, due to the different sizes of the upper and lower circular surfaces, the distance between the upper and lower ends of the bevel gear and the inner wall of the cylinder is different. This results in uneven heating of the upper and lower bevel gear, affecting the tooth strength of the upper and lower parts of the bevel gear. In market use, the different tooth strength of the upper and lower bevel gear can lead to wear or breakage of the teeth in the weaker parts of the bevel gear, affecting the normal use of the bevel gear.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1) When using this waste heat recovery heat treatment equipment for gear processing, compared with the traditional heating cylinder, this equipment uses heating guide plates and sliding guide plates to rotate and fully fit with the bevel gear teeth. Multiple heating guide plates and sliding guide plates are connected end to end to fully cover the bevel gear teeth and the tooth grooves between the two teeth, so that the bevel gear teeth are heated evenly during the heating process, ensuring the strength of the bevel gear during the processing, preventing wear or breakage at the weaker parts of the bevel gear teeth, and thus extending the service life of the bevel gear.

Under the action of the spring shaft, the heating guide plate is suitable for teeth with different slopes. At the same time, the heating guide plate and the sliding guide plate can heat teeth with different slopes, increasing the function of the equipment.

[0027] 3) When using the waste heat recovery heat treatment equipment for gear processing, heating guide plates and sliding guide plates are added according to the number of teeth of the same batch of bevel gears.

[0042] Example 1: Please refer to Figure 1 - Figure 12A waste heat recovery heat treatment device for gear processing includes a housing 1. A fixed disk 2 is fixedly installed inside the housing 1. A rotating groove 3 is formed on the surface of the fixed disk 2. Several matching rotating blocks 4 are slidably connected inside the rotating groove 3. A bracket 5 is fixedly installed on the top surface of each rotating block 4. Two fixing plates 6 are correspondingly fixedly installed on the inner side of each bracket 5. A through-type sliding groove 7 is formed on the surface of the fixing plate 6. A matching slide frame 8 is slidably connected inside the sliding groove 7. A through-type sliding rod 9 is slidably connected to the surface of the slide frame 8 for fixing... The guide movement of the frame 10 is guided by a ramp block 24 fixedly installed on the inner side of any one of the brackets 5 for pressing the slide bar 9 to slide. The other end of the slide bar 9 is fixedly connected to the fixed frame 10. The fixed frame 10 is rotatably connected to the inside of the fixed frame 10. A heating guide plate 13 is fixedly installed on the outside of the rotating cylinder 12. The heating guide plate 13 and the sliding guide plate 14 are conventional electric heating plates in the prior art. The heating guide plate 13 is slidably connected to a matching sliding guide plate 14. A through guide rod 15 is slidably connected to the surface of the fixed plate 2. A placement plate 16 is fixedly installed on the top surface of the guide rod 15. A rod 17 is fixedly installed in the center of the surface of the tray 16. A bevel gear 18 to be heated is placed on the surface of the tray 16. The bevel gear 18 is a conventional bevel gear in the prior art. According to the slope of the teeth of the bevel gear 18, the heating guide plate 13 is squeezed and rotated by the teeth, which drives the rotating drum 12 to rotate. The teeth of the bevel gear 18 then squeeze the rotating plate 29, which drives the sliding plate 33 to rotate, causing the sliding guide plate 14 to drive out from the slot 30. Multiple heating guide plates 13 and sliding guide plates 14 are connected end to end, completely covering the teeth of the bevel gear 18 and the grooves between two teeth. The guide plate 14 works simultaneously to heat the teeth of the bevel gear 18 and the grooves between the teeth. Compared with the traditional heating cylinder, this device uses heating guide plates 13 and sliding guide plates 14 to rotate and fully fit with the teeth of the bevel gear 18. Multiple heating guide plates 13 and sliding guide plates 14 are connected end to end to fully cover the teeth of the bevel gear 18 and the grooves between the teeth. This ensures that the teeth of the bevel gear 18 are heated evenly during the heating process, guarantees the strength of the bevel gear 18 during the processing, prevents wear or breakage at the weaker parts of the teeth of the bevel gear 18, and thus extends the service life of the bevel gear 18.

[0043] Both ends of the rotating drum 12 are provided with spring shafts 11. The rotating drum 12 is rotatably connected to the fixed frame 10 through the two spring shafts 11. The heating guide plate 13 has a slot 30 inside that matches the sliding guide plate 14. The sliding guide plate 14 is slidably connected to the heating guide plate 13 through the slot 30. According to the slope of the bevel gear 18 teeth, the heating guide plate 13 is squeezed by the teeth and rotates the rotating drum 12 and the spring shafts 11, so that the heating guide plate 13 and the bevel gear 18 teeth are in contact. Under the action of the spring shafts 11, the heating guide plate 13 is suitable for teeth with different slopes. At the same time, the heating guide plate 13 and the sliding guide plate 14 can heat teeth with different slopes, increasing the function of the equipment.

[0044] A disc 19 is fixedly mounted on the bottom surface of the guide rod 15. A first spring 20 for resetting is sleeved on the surface of the guide rod 15. One end of the first spring 20 is fixedly connected to the surface of the disc 19, and the other end of the first spring 20 is fixedly connected to the bottom surface of the fixed disc 2. The first spring 20 is used for the movement reset of the guide rod 15.

[0045] Multiple support rods 21 are provided between the fixed plate 2 and the outer shell 1. The fixed plate 2 is fixedly connected to the inner bottom surface of the outer shell 1 through the support rods 21. A circular groove 22 is opened on the inner bottom surface of the rotating groove 3. Multiple matching sliders 23 are slidably connected inside the circular groove 22. The number of sliders 23 is the same as the number of rotating blocks 4, and the top surface of any slider 23 is fixedly connected to the bottom surface of the corresponding rotating block 4.

[0046] A ball head 25 is fixedly installed at one end of the slide rod 9. The ball head 25 contacts the slope surface of the ramp block 24. A second spring 26 for its reset movement is sleeved on the surface of the slide rod 9. One end of the second spring 26 is fixedly connected to the surface of the slide 8, and the other end of the second spring 26 is fixedly connected to the ball head 25.

[0047] Each slide 8 has a pressure plate 27 fixedly installed on its bottom surface. The pressure plate 27 is L-shaped and is located below the placement plate 16. The placement plate 16 moves downward, causing multiple pressure plates 27 to move downward as well.

[0048] The inner wall of the heating guide plate 13 has a slot 28 that communicates with the slot 30. A rotating plate 29 is rotatably connected inside the slot 28. Both sides of one end of the rotating plate 29 are provided with elastic reset shafts 31. The rotating plate 29 is rotatably connected to the slot 28 through the elastic reset shafts 31. Two supports 32 are fixedly installed on the surface of the rotating plate 29. A sliding plate 33 is rotatably connected between the two supports 32. Two fixed seats 34 are fixedly installed on the surface of the sliding guide plate 14. A rotating shaft 35 is provided between the two sides of one end of the sliding plate 33 and the two fixed seats 34. The sliding plate 33 is rotatably connected to the fixed seats 34 through the rotating shafts 35. The rotating plate 29 is reset under the action of the elastic reset shafts 31. The sliding plate 33 follows the rotating plate 29 to reset and moves the sliding guide plate 14 into the slot 30.

[0049] An electric telescopic rod 36 is fixedly installed on the inner top surface of the outer casing 1, and a controller 37 is fixedly installed on the surface of the outer casing 1. The controller 37 is a conventional programmable control device in the prior art. The electric telescopic rod 36 is electrically connected to the controller 37 through a wire. The electric telescopic rod 36 is a conventional electrically controlled push rod in the prior art. A heating button 38 is provided on the surface of the outer casing 1. The heating button 38 is a conventional heating button in the prior art. The heating button 38 is used to control the heating guide plate 13 and the sliding guide plate 14 to heat the teeth of the bevel gear 18. A scale 42 is provided on the surface of the fixed plate 2. The scale 42 is a conventional rounded corner scale in the prior art. The rotating block 4 is manually adjusted so that the rotating block 4 rotates in the rotating groove 3, which moves the bracket 5, the fixed plate 6, the slide 8, the slide rod 9, the fixed frame 10, the spring shaft 11, the rotating cylinder 12, the heating guide plate 13 and the sliding guide plate 14. The scale 42 is observed in real time to ensure that the heating guide plate 13 corresponds to the teeth.

[0050] The steps of using this invention are as follows: Before heating the bevel gear 18 using the waste heat recovery heat treatment equipment for gear processing, the rotating block 4 is first fixed inside the rotating groove 3. Then, the bevel gear 18 is passed through the surface of the insert rod 17 and placed on the surface of the placement plate 16. The operating controller 37 controls the electric telescopic rod 36 to extend and act on the top surface of the bevel gear 18. As the electric telescopic rod 36 continues to extend, the bevel gear 18 and the placement plate 16 move downwards, causing the guide rod 15 to move downwards and stretching the first spring 20. During the downward movement of the placement plate 16, the placement plate 16 moves downwards along with multiple pressure plates 27. At this time, the slide 8 follows the pressure plates 27 downwards, causing the slide rod 9 to move downwards. The ball head 25 is squeezed by the ramp block 24, causing the slide rod 9 to move towards the cone. The gear 18 moves in the direction of compression, compressing the second spring 26. The slide rod 9 moves in the direction of the bevel gear 18, causing the fixed frame 10, spring shaft 11, rotating cylinder 12, heating guide plate 13, and sliding guide plate 14 to move. Before the heating guide plate 13 contacts the teeth of the bevel gear 18, the heating guide plate 13 and the sliding guide plate 14 are squeezed by the slope of the teeth. According to the slope of the teeth of the bevel gear 18, the heating guide plate 13 rotates, causing the rotating cylinder 12 to rotate. When the heating guide plate 13 and the sliding guide plate 14 are fully engaged with the teeth of the bevel gear 18, during the engagement process, the teeth of the bevel gear 18 first squeeze the rotating plate 29. After being squeezed, the rotating plate 29 rotates with the sliding plate 33, causing the sliding guide plate 14 to drive out of the slot 30. When the rotating plate 29 is retracted into the slot 28, the sliding guide plate 14... 14. Once the extension is complete, the heating guide plate 13 and the sliding guide plate 14 contact the teeth of the bevel gear 18, stopping the operation of the electric telescopic rod 36. Multiple heating guide plates 13 and sliding guide plates 14 are connected end-to-end, completely covering the teeth of the bevel gear 18 and the grooves between the teeth. At this point, the heating button 38 is activated, causing the heating guide plates 13 and the sliding guide plates 14 to work simultaneously to heat the teeth of the bevel gear 18 and the grooves between the teeth. After heating, the electric telescopic rod 36 retracts, and the placement plate 16 resets under the action of the first spring 20, also resetting the bevel gear 18. Since the ball head 25 is on the slope of the ramp block 24, the second spring 26 resets, causing the ball head 25 to move along the ramp block 24 (at this time, the elastic force of the second spring 26 is greater than that of the slide 8 and the pressure plate 2). (The combined gravity of slide 8 and sliding friction between slide 8 and slide groove 7), during the resetting process of slide rod 9, slide 8 moves upward to reset. The resetting movement of slide rod 9 also moves fixed frame 10, spring shaft 11, rotating cylinder 12, heating guide plate 13 and sliding guide plate 14 to reset. At this time, rotating plate 29 resets under the action of elastic reset shaft 31. Slide plate 33 follows rotating plate 29 to reset and moves sliding guide plate 14 into slot 30. After bevel gear 18 resets, it is clamped and removed by existing clamping pliers. According to the slope of the bevel gear 18 teeth, heating guide plate 13 is squeezed and rotated by the teeth, causing rotating cylinder 12 to rotate. The teeth of bevel gear 18 then squeeze rotating plate 29 and slide plate 33 to rotate, causing sliding guide plate 14 to drive out of slot 30.Multiple heating guide plates 13 and sliding guide plates 14 are connected end-to-end to completely cover the teeth of the bevel gear 18 and the grooves between the teeth. The heating guide plates 13 and sliding guide plates 14 work simultaneously to heat the teeth of the bevel gear 18 and the grooves between the teeth. Compared to a traditional heating cylinder, this device uses heating guide plates 13 and sliding guide plates 14 to rotate and completely fit with the teeth of the bevel gear 18. The multiple heating guide plates 13 and sliding guide plates 14 are connected end-to-end to completely cover the teeth of the bevel gear 18 and the grooves between the teeth, ensuring that the teeth of the bevel gear 18 are heated evenly during the heating process. Uniform heating ensures the strength of the bevel gear 18 during processing, preventing wear or breakage at weaker points on the teeth and thus extending its service life. Based on the slope of the bevel gear 18 teeth, the heating guide plate 13, under pressure from the teeth, rotates the rotating drum 12 and spring shaft 11, causing the heating guide plate 13 to engage with the teeth of the bevel gear 18. Under the action of the spring shaft 11, the heating guide plate 13 is suitable for teeth with different slopes. Simultaneously, the heating guide plate 13 and the sliding guide plate 14 can heat teeth with different slopes, increasing the equipment's functionality.

[0051] Example 2: Please refer to Figure 1 - Figure 12 The difference from embodiment 1 is that the fixed plate 2 has two matching clamps 39 on its exterior. Clamping blocks 40 are fixedly installed on the inner sides of both clamps 39. Each rotating block 4 has a clamping groove 41 on its outer surface that matches the clamping block 40. The surfaces of both clamps 39 are provided with locking screws 45 for tightening. First, the rotating block 4 is inserted into the rotating groove 3 through the second through groove 44. At this time, the pressure plate 27 moves to the lower part of the placement plate 16 through the first through groove 43. According to the degree between the number of teeth, manually adjust the rotating block 4 so that the rotating block 4 rotates in the rotating groove 3, which moves the bracket 5, the fixing plate 6, the slide 8, the slide rod 9, the fixing frame 10, the spring shaft 11, the rotating cylinder 12, the heating guide plate 13 and the sliding guide plate 14, so that the heating guide plate 13 corresponds to the teeth. Then, the two clamps 39 are tightened by the locking screw 45. At this time, the clamp 40 is inserted into the clamping groove 41, fixing the rotating block 4 inside the rotating groove 3. This method is suitable for processing bevel gears 18 with different numbers of teeth.

[0052] The surface of the placement plate 16 is provided with a first through groove 43 that matches the pressure plate 27, and the surface of the fixed plate 2 is provided with a second through groove 44 that matches the rotating block 4. The first through groove 43 and the second through groove 44 are in corresponding positions. A card seat 46 is fixedly installed on the surface of the rotating cylinder 12, and a card block 47 that matches the card seat 46 is fixedly installed on the surface of the heating guide plate 13. The card seat 46 and the card block 47 are engaged with each other. When the curvature of the bevel gear 18 teeth is different, the clamping block 40 and the clamping groove 41 are disengaged from each other, and the heating guide plate 13 and the sliding guide plate 14 suitable for the curvature of the teeth are replaced, so as to realize the heating of the bevel gear 18 with different tooth curvatures and increase the functionality of the equipment.

[0053] The steps for using this invention are as follows: When using this waste heat recovery heat treatment equipment for gear processing, the sizes of the bevel gears 18 produced in the factory vary, and the number of teeth and the curvature of the teeth also differ. Based on the number of teeth of the same batch of bevel gears 18, heating guide plates 13 and sliding guide plates 14 can be added. During installation, the rotating block 4 is first inserted into the rotating groove 3 through the second through groove 44. At this time, the pressure plate 27 moves to below the placement plate 16 through the first through groove 43. Based on the degree between the teeth, the rotating block 4 is manually adjusted so that it rotates within the rotating groove 3, carrying the bracket 5 and the fixing plate 6. The slide 8, slide rod 9, fixed frame 10, spring shaft 11, rotating drum 12, heating guide plate 13, and sliding guide plate 14 move, so that the heating guide plate 13 corresponds to the teeth. Then, the two clamps 39 are fastened by the locking screw 45. At this time, the clamping block 40 is inserted into the clamping groove 41, fixing the rotating block 4 inside the rotating groove 3. This is suitable for processing bevel gears 18 with different numbers of teeth. When the curvature of the bevel gear 18 teeth is different, the clamping block 40 and the clamping groove 41 are disengaged from each other, and the heating guide plate 13 and sliding guide plate 14 suitable for the curvature of the teeth are replaced, so as to realize the heating of bevel gears 18 with different tooth curvatures and increase the functionality of the equipment.
