[0003] Chinese Patent Application No. CN202111370438.5 relates to the technical field of gear processing, and in particular, to a waste heat recovery heat treatment device for gear processing and a gear processing process. It is mainly a waste heat recovery heat treatment device for gear processing, including a furnace body, and a waste heat recovery structure is wrapped outside the furnace body. The waste heat recovery structure includes a housing sleeved outside the furnace body and heat exchange tubes arranged between the inner wall of the housing and the outer wall of the furnace body, and a heat conduction medium is provided inside the housing.

[0004] In the above technical solution, it is possible to store and utilize the heated water source, or to use this hot water for subsequent cleaning needs, and the heat energy can be recycled to save energy. However, in the solution, the furnace body is cylindrical. When heating a general circular gear, uniform heating of the circular gear can be achieved. However, in real life, gears are diverse. When heating a bevel gear, due to the different sizes of the upper and lower end circular surfaces of the bevel gear, when the bevel gear is placed in the cylindrical shape for heating, the distances between the upper and lower ends of the bevel gear and the inner wall of the cylindrical shape are different, resulting in uneven heating of the upper and lower parts of the bevel gear, affecting the tooth profile strength of the upper and lower parts of the bevel gear. When used in the market, the different tooth profile strengths of the upper and lower teeth of the bevel gear will cause tooth wear or fracture at the part with lower strength of the bevel gear, affecting the normal use of the bevel gear.

Observe the scale 42 in real time so that the heating guide piece 13 corresponds to the teeth.

[0036] Usage steps of the present invention: When the waste heat recovery heat treatment equipment for gear processing is in use, before heating the bevel gear 18, first fix the rotating block 4 inside the rotating groove 3, then put the bevel gear 18 on the surface of the inserting rod 17 and place it on the surface of the placing plate 16. Operate the controller 37 to control 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, at this time, the bevel gear 18 and the placing plate 16 move downward, driving the guide rod 15 to move downward and stretching the first spring 20. During the downward movement of the placing plate 16, the placing plate 16 drives a plurality of pressing plates 27 to move downward. At this time, the sliding frame 8 follows the pressing plate 27 to move downward, driving the sliding rod 9 to move downward. The ball head 25 is squeezed by the slope block 24 and drives the sliding rod 9 to move towards the bevel gear 18, compressing the second spring 26. The sliding rod 9 moving towards the bevel gear 18 drives the fixing frame 10, the spring shaft 11, the rotating cylinder 12, the heating guide piece 13 and the sliding connection guide piece 14 to move. Before the heating guide piece 13 contacts the tooth flank of the bevel gear 18, since the heating guide piece 13 and the sliding connection guide piece 14 are squeezed by the tooth flank slope, according to the slope of the tooth flank of the bevel gear 18, at this time, the heating guide piece 13 rotates, driving the rotating cylinder 12 to rotate. When the heating guide piece 13 and the sliding connection guide piece 14 are completely attached to the tooth flank of the bevel gear 18, during the attachment process, the tooth flank of the bevel gear 18 first squeezes the rotating plate 29. After being squeezed, the rotating plate 29 drives the sliding plate 33 to rotate, causing the sliding connection guide piece 14 to move out of the slot 30. When the rotating plate 29 is received into the slot 28, at this time, the sliding connection guide piece 14 extends out, and the heating guide piece 13 and the sliding connection guide piece 14 contact the tooth flank of the bevel gear 18. Stop the electric telescopic rod 36 from working. A plurality of heating guide pieces 13 and sliding connection guide pieces 14 are connected end to end with each other, completely covering the tooth flank of the bevel gear 18 and the tooth groove between two tooth flanks. At this time, turn on the heating button 38, so that the heating guide piece 13 and the sliding connection guide piece 14 work simultaneously to heat the tooth flank of the bevel gear 18 and the tooth groove between two tooth flanks. After heating is completed, the electric telescopic rod 36 retracts, and the placing plate 16 resets under the action of the first spring 20, driving the bevel gear 18 to reset. Since the ball head 25 is on the slope surface of the slope block 24, at this time, the second spring 26 resets and drives the ball head 25 to move along the slope block 24 (at this time, the elastic force of the second spring 26 is greater than the gravity of the sliding frame 8 and the pressing plate 27 together and the sliding friction between the sliding frame 8 and the sliding groove 7). During the reset process of the sliding rod 9, it drives the sliding frame 8 to move upward for reset. The reset movement of the sliding rod 9 drives the fixing frame 10, the spring shaft 11, the rotating cylinder 12, the heating guide piece 13 and the sliding connection guide piece 14 to move for reset. At this time, the rotating plate 29 resets under the action of the elastic reset shaft 31, and the sliding plate 33 follows the rotating plate 29 to reset, driving the sliding connection guide piece 14 to move towards the inside of the slot 30. After the bevel gear 18 is reset, it is clamped and taken out by an existing clamping pliers. According to the slope of the tooth flank of the bevel gear 18, the heating guide piece 13 is squeezed by the tooth flank and rotates, driving the rotating cylinder 12 to rotate. The tooth flank of the bevel gear 18 then squeezes the rotating plate 29, driving the sliding plate 33 to rotate, causing the sliding connection guide piece 14 to move out of the slot 30.A plurality of heating guide plates 13 and sliding connection guide plates 14 are connected end to end with each other, completely covering the teeth of the bevel gear 18 and the tooth grooves between two teeth. The heating guide plates 13 and the sliding connection guide plates 14 work simultaneously to heat the teeth of the bevel gear 18 and the tooth grooves between two teeth. Compared with the traditional heating cylinder, this device rotates the heating guide plates 13 and the sliding connection guide plates 14 to be completely attached to the teeth of the bevel gear 18 through rotation. The plurality of heating guide plates 13 and the sliding connection guide plates 14 are connected end to end with each other, completely covering the teeth of the bevel gear 18 and the tooth grooves between two teeth, so that the teeth of the bevel gear 18 are evenly heated during the heating process, ensuring the strength during the processing of the bevel gear 18, preventing wear or fracture at the lower strength part of the teeth of the bevel gear 18, and thus extending the service life of the bevel gear 18; according to the slope change of the teeth of the bevel gear 18, after the heating guide plate 13 is extruded by the teeth, it drives the rotating cylinder 12 and the spring shaft 11 to rotate, so that the heating guide plate 13 is attached to the teeth of the bevel gear 18. Under the action of the spring shaft 11, the heating guide plate 13 is applicable to teeth with different slopes. At the same time, the heating guide plate 13 and the sliding connection guide plate 14 can heat teeth with different slopes, increasing the functions of the device.,

When the curvature of the teeth of the bevel gear 18 is different, the heating guide plate 13 and the sliding connection guide plate 14 suitable for the curvature of the teeth are replaced by separating the clamping block 40 and the clamping groove 41 from each other, realizing the heating of bevel gears 18 with different curvatures of teeth and increasing the functionality of the device.

[0039] Usage steps of the present invention: When the waste heat recovery heat treatment equipment for gear processing is in use, the bevel gears 18 produced by the factory are of different sizes, and the number of teeth and the curvature of the tooth flanks of the bevel gears 18 are both variable. According to the number of teeth of the same batch of bevel gears 18, heating guide pieces 13 and sliding connection guide pieces 14 can be installed according to the number of teeth of the same batch of bevel gears 18. When installing, first insert the rotating block 4 into the rotating groove 3 through the second through groove 44. At this time, the pressing plate 27 moves to the lower part of the placing plate 16 through the first through groove 43. According to the angle between the teeth, manually adjust the rotating block 4 so that the rotating block 4 rotates in the rotating groove 3 and drives the bracket 5, the fixing plate 6, the sliding frame 8, the sliding rod 9, the fixing frame 10, the spring shaft 11, the rotating cylinder 12, the heating guide piece 13 and the sliding connection guide piece 14 to move, so that the heating guide piece 13 corresponds to the tooth flanks. Then, fasten the two clamps 39 with the locking wire 45. At this time, the clamping block 40 is inserted into the clamping groove 41 to fix the rotating block 4 inside the rotating groove 3, which is applicable to the processing of bevel gears 18 with different numbers of teeth; when the curvature of the tooth flanks of the bevel gear 18 is different, the clamping block 40 and the clamping groove 41 are disengaged from each other, and the heating guide piece 13 and the sliding connection guide piece 14 suitable for the curvature of the tooth flanks are replaced to realize the heating of bevel gears 18 with different curvatures of tooth flanks, increasing the functionality of the equipment.
