Description

Technical Field

[0001] The invention belongs to the technical field of diaphragm spring processing, in particular to a diaphragm spring stress relief annealing furnace. Background Art

[0002] Diaphragm springs are widely used in the clutch systems of cars, light, medium and heavy trucks, buses and other vehicles. They not only improve the performance of the clutch, but also improve the reliability and economy of the whole vehicle. The diaphragm spring consists of a disc spring part and a release finger part. It is widely used in the fields of automobile clutches. The diaphragm spring can keep the spring pressure basically unchanged within the allowable wear range of the friction plate, thereby ensuring that the torque transmitted by the clutch remains roughly unchanged. The diaphragm spring plays the role of a compression spring and a release lever, reducing the number of parts and making the structure more compact. When rotating at high speed, the compression force of the diaphragm spring is less reduced and the performance is relatively stable. Since the large cross-section ring of the diaphragm spring contacts the pressure plate, the pressure is evenly distributed, which helps to extend the service life of the friction plate.

[0003] The diaphragm spring needs to be annealed during the processing. The diaphragm spring stress relief annealing furnace is a heat treatment equipment used to eliminate the residual stress inside the diaphragm spring. Stress relief annealing is a heat treatment process that aims to remove the internal stress introduced by cold processing (such as cold rolling or cold forming) by slowly heating to a certain temperature and then keeping it warm, and then cooling it with the furnace. This process is very important to ensure that the diaphragm spring can maintain dimensional stability and avoid rupture due to stress concentration during subsequent processing and use.

[0004] During the annealing process of the diaphragm spring, batches of diaphragm springs are stacked on a placement seat and added to the annealing furnace. It is difficult to arrange the diaphragm springs in a dispersed manner, and it is time-consuming and labor-intensive. The diaphragm springs in the stacked state will have dead corners for heating, and the diaphragm springs are stationary in the annealing furnace and can only be heated by heat transfer between multiple diaphragm springs, which can easily lead to uneven heating, which is not conducive to the uniform stress relief annealing of the diaphragm spring. Summary of the invention

[0005] In order to overcome the above-mentioned defects, the present invention provides a diaphragm spring stress relief annealing furnace, which solves the problem that batches of diaphragm springs are stacked on a placement seat and added to the annealing furnace, which makes it difficult to disperse the diaphragm springs and is time-consuming and labor-intensive. The diaphragm springs in the stacked state will have dead corners for heating, and the diaphragm springs are stationary in the annealing furnace and can only be heated through heat transfer between multiple diaphragm springs, which easily leads to the problem of uneven heating.

[0006] The objects of the present invention are:

[0007] The mounting tube drives the sleeved multiple diaphragm springs to rotate, so that the diaphragm springs are evenly heated. The driven gear can revolve around the driving gear during the rotation process. At the same time, the driven gear drives the multiple diaphragm springs to rotate around the inside of the annealing furnace body through the rotating shaft and the mounting tube, abandoning the traditional stacking method for annealing. The continuously rotating diaphragm springs can be evenly heated without any heating dead corners, which is conducive to the uniform stress relief annealing of the diaphragm springs.

When removing the diaphragm spring, the locking state of the diaphragm spring by the limit bar can be released by reversing the adjustment assembly.

The side of the deflection assembly away from the motor is connected to a plurality of mounting tubes. The mounting tubes are located in the main body of the annealing furnace. An adjustment assembly is installed inside the mounting tubes. A sliding hole is opened outside the mounting tubes at a position corresponding to the adjustment assembly, and the end of the adjustment assembly passes through the sliding hole.

The top of the counterweight base is fixed to the bottom of the furnace cover, and a triangular support block is provided on one side of the counterweight base.

[0014] As a further solution of the present invention: the deflection assembly includes two fixed brackets, a driving gear is movably connected between the two fixed brackets, the driving gear is externally meshed with three driven gears, the three driven gears are movably connected between the two fixed brackets, the three driven gears are externally meshed with a fixed gear ring, one end of the driving gear close to the furnace cover passes through the fixed bracket and is fixed to the output shaft of the motor, and the angle between two adjacent driven gears is one hundred and twenty degrees.

[0015] As a further solution of the present invention: one end of the driven gear is connected to a rotating shaft, the rotating shaft passes through one of the fixed brackets, and one end of the rotating shaft away from the fixed bracket is fixed to one end of the mounting tube.

[0016] As a further solution of the present invention: a slip ring is fixedly connected to the end of the fixed bracket on the rotating shaft, the slip ring is slidably connected in the slideway, the cross-sectional shape of the slip ring is T-shaped, and the shape of the slip ring is adapted to the shape of the slideway.

[0017] As a further solution of the present invention: the adjusting assembly includes a screw rod, both ends of which are respectively installed on both sides of the mounting tube through bushings, the thread directions of the two sides outside the screw rod are opposite, and the two sides outside the screw rod are respectively threadedly connected with nuts, and the four sides of the nut are respectively hinged with support rods through pins, and the support rods are slidably connected in the sliding hole.

[0018] As a further solution of the present invention: one end of the support rod away from the nut is hinged to a limit bar through a pin shaft, and the limit bar is of arc-shaped design. Both sides of the inner wall of the limit bar are respectively fixedly connected to the limit rods, and the limit rods pass through the mounting tube and extend to the interior of the mounting tube. A turning handle is fixed to the end of the screw rod away from the deflection assembly, and the turning handle is embedded in the end of the mounting tube.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, a batch of diaphragm springs are sleeved outside the erection tube, so that the adjustment component is located on the inner wall of the diaphragm spring. The adjustment component is operated to make it close to the diaphragm spring, so as to play a role in supporting and limiting the diaphragm spring. After the limiting work of the diaphragm spring is completed, the transfer component is pushed so that the erection tube and the diaphragm spring can be sent into the annealing furnace body. When the annealing furnace body is working, the motor is controlled to work so that the output shaft of the motor drives the driving gear to rotate through the fixed bracket. Since the driving gear is meshed and connected with a plurality of driven gears, the driving gear drives the plurality of driven gears to rotate synchronously, and the driven gear drives the plurality of driven gears to rotate synchronously through the rotating shaft. The movable mounting cylinder rotates, and the mounting cylinder drives the multiple diaphragm springs that are sleeved to rotate, so that the diaphragm springs are evenly heated, and the multiple driven gears are meshed and connected with the fixed gear ring, and the fixed gear ring is fixed inside the furnace cover and does not rotate. Therefore, the multiple driven gears can revolve around the driving gear during the self-rotation process. At the same time, the driven gear drives the multiple diaphragm springs to rotate around the inside of the annealing furnace body through the rotating shaft and the mounting cylinder, abandoning the traditional stacking method for annealing. The continuously rotating diaphragm spring can be heated evenly without any heating dead corner, which is beneficial to the uniform stress relief annealing of the diaphragm spring.

[0021] 2. In the present invention, after the diaphragm spring is sleeved outside the mounting tube, a tool is used to rotate the handle, which drives the screw rod to rotate inside the mounting tube. Since the threads on the two sides outside the screw rod are in opposite directions, the two nuts can move relatively inside the mounting tube. The two ends of the support rod are respectively hinged to the nut and the limit bar through a pin shaft, so that the nut can push the support rod to deflect during the movement, so that the support rod can slide in the sliding hole, thereby limiting the nut and preventing the nut from rotating by itself and affecting the stability of the limit bar adjustment. During the deflection of the support rod, the limit bar can be pushed to enable the four limit bars to expand outward synchronously and contact the inner wall of the diaphragm spring, thereby supporting and limiting all diaphragm springs externally mounted on the mounting tube, thereby improving the convenience of operation and preventing the diaphragm spring from detaching from the mounting tube during the rotation.

[0022] 3. In the present invention, by operating the two handles outside the furnace cover, the furnace cover can drive the transfer assembly to move, and the multiple moving wheels at the bottom of the transfer assembly can roll, thereby reducing the friction when moving the furnace cover and alleviating the workload. The furnace cover then drives the fixed gear ring and multiple mounting tubes to move out of the annealing furnace body, and then adjusts the angle of the transfer assembly so that the annealed diaphragm spring is completely exposed to the outside. When removing the diaphragm spring, the handle is adjusted in the reverse direction so that the handle drives the screw rod to rotate, and the two nuts outside the screw rod move away from each other and pull the support rod, and the support rod drives the limit bar to approach the mounting tube, so that the locking state of the diaphragm spring by the limit bar can be released, and the diaphragm spring can be completely removed by pushing the diaphragm spring from the end of the mounting tube, thereby improving the convenience of unloading operation.

[0032] The technical solution of the present application is further described in detail below in conjunction with specific implementation methods.

[0033] like Figure 1-8 As shown, the present invention provides a technical solution: a diaphragm spring stress relief annealing furnace, comprising an annealing furnace main body 1, a supporting leg 2 is provided at the bottom of the annealing furnace main body 1, a furnace cover 3 is installed on one side of the annealing furnace main body 1, two handles are installed on the side of the furnace cover 3 away from the annealing furnace main body 1, a sealing ring is installed on the side of the furnace cover 3 close to the annealing furnace main body 1, and a plurality of fixing grooves are provided on the outer wall of the furnace cover 3. Due to the provision of the fixing grooves, after the furnace cover 3 contacts the annealing furnace main body 1, bolts can pass through the fixing grooves and be connected to the annealing furnace main body 1, thereby improving the stability of the connection between the annealing furnace main body 1 and the furnace cover 3.

[0034] A transfer assembly 4 is installed at the bottom of the furnace cover 3, and the transfer assembly 4 includes a counterweight base 401. Moving wheels 402 are respectively installed at the four corners of the bottom of the counterweight base 401. The top of the counterweight base 401 is fixed to the bottom of the furnace cover 3. A triangular support block is provided on one side of the counterweight base 401. The triangular support block has good triangular stability and can support the corners of the counterweight base 401 to improve the supporting stability of the counterweight base 401 on the furnace cover 3. The counterweight base 401 can support the furnace cover 3 and the diaphragm spring on the furnace cover 3 to prevent the furnace cover 3 from tipping over; the furnace cover 3 can drive the counterweight base 401 to move, so that the multiple moving wheels 402 at the bottom of the counterweight base 401 can roll, thereby reducing the friction when moving the furnace cover 3 and alleviating the workload.

[0035] A fixed gear ring 11 is installed inside the furnace cover 3, and a deflection assembly 5 is arranged inside the fixed gear ring 11. The deflection assembly 5 includes two fixed brackets 501, and a driving gear 502 is movably and rotatably connected between the two fixed brackets 501. The driving gear 502 is externally meshed with three driven gears 503. The three driven gears 503 are movably and rotatably connected between the two fixed brackets 501, and the three driven gears 503 are externally meshed with the fixed gear ring 11.

[0036] A slideway 6 is provided on one side of the furnace cover 3 close to the interior of the annealing furnace body 1, and the deflection assembly 5 is slidably connected in the slideway 6. A motor 7 is installed on one side of the furnace cover 3; a slip ring 504 is fixedly connected to the end of the fixed bracket 501, and the slip ring 504 is slidably connected in the slideway 6. The cross-sectional shape of the slip ring 504 is T-shaped, and the shape of the slip ring 504 is adapted to the shape of the slideway 6. Through the mutual cooperation between the slip ring 504 and the slideway 6, the slideway 6 can support and limit the slip ring 504, so that the fixed bracket 501 is not easily displaced during the rotation process.

[0037] One end of the driving gear 502 close to the furnace cover 3 passes through the fixed bracket 501 and is fixed to the output shaft of the motor 7. The angle between two adjacent driven gears 503 at the radius position of the circle where the fixed gear ring 11 is located is one hundred and twenty degrees. Since the driving gear 502 is meshed and connected with multiple driven gears 503, the driving gear 502 will drive the multiple driven gears 503 to rotate synchronously.

[0038] One end of the driven gear 503 is connected to a rotating shaft 505, which passes through one of the fixed brackets 501, and one end of the rotating shaft 505 away from the fixed bracket 501 is fixed to one end of the mounting tube 8. In this embodiment, the fixed bracket 501 is composed of three brackets, and the driven gear 503 is installed on each bracket respectively. The driven gear 503 drives the mounting tube 8 to rotate through the rotating shaft 505, and the mounting tube 8 drives the sleeved multiple diaphragm springs to rotate, so that the diaphragm springs are evenly heated; because the driven gear 503 is meshed and connected with the fixed gear ring 11, and the fixed gear ring 11 is fixed inside the furnace cover 3 and will not rotate, the multiple driven gears 503 can revolve around the driving gear 502 during the rotation process, so as to facilitate a wide range of adjustment of the mounting tube 8 and the diaphragm spring.

[0039] The mounting tube 8 is located in the annealing furnace body 1, and an adjustment assembly 9 is installed inside the mounting tube 8. The adjustment assembly 9 includes a screw rod 901. The two ends of the screw rod 901 are respectively installed on the two sides of the mounting tube 8 through a sleeve. The threads on the two sides of the screw rod 901 are in opposite directions, and the two sides of the screw rod 901 are respectively threadedly connected with nuts 902. The four sides of the nut 902 are respectively hinged with support rods 903 through pins.

[0040] A sliding hole 10 is opened at the position corresponding to the support rod 903 outside the mounting tube 8, and the end of the support rod 903 passes through the sliding hole 10, and the support rod 903 is slidably connected in the sliding hole 10. Since the threads on the two sides outside the screw rod 901 are in opposite directions, the two nuts 902 can move relative to each other inside the mounting tube 8. The two ends of the support rod 903 are respectively hinged to the nut 902 and the limit strip 904 through a pin shaft, so that the nut 902 can push the four support rods 903 to deflect during the movement, which is convenient for synchronous adjustment of multiple support rods 903.

[0041] One end of the support rod 903 away from the nut 902 is hinged to the limit bar 904 through a pin shaft. The limit bar 904 is designed to be arc-shaped. The two sides of the inner wall of the limit bar 904 are respectively fixedly connected to the limit rod 905. The limit rod 905 passes through the mounting tube 8 and extends to the interior of the mounting tube 8. The end of the screw rod 901 away from the fixed bracket 501 is fixed with a turning handle 906, and the turning handle 906 is embedded in the end of the mounting tube 8. Because the limit bar 904 is provided, the limit bar 904 can be pushed during the deflection of the support rod 903, so that the four limit bars 904 can be synchronously expanded outward and contact the inner wall of the diaphragm spring, thereby supporting and limiting all diaphragm springs connected to the outer shell of the mounting tube 8, preventing the diaphragm spring from detaching from the mounting tube 8 during the rotation; because the limit rod 905 is provided, the limit rod 905 can slide on the mounting tube 8, thereby supporting and limiting the limit bar 904, preventing the limit bar 904 from deviating and affecting the stability of the support and limitation of the diaphragm spring.

[0042] The working principle of the present invention is:

[0043] When in use, a batch of diaphragm springs are sleeved outside the mounting tube 8, and a tool is used to rotate the handle 906, which drives the screw rod 901 to rotate inside the mounting tube 8. Because the threads on the two sides outside the screw rod 901 are in opposite directions, the two nuts 902 can move relatively inside the mounting tube 8, and the two ends of the support rod 903 are respectively hinged to the nut 902 and the limit bar 904 through the pin shaft, so that the nut 902 can push the support rod 903 to deflect during the movement, and the limit bar 904 can be pushed during the deflection of the support rod 903, so that the four limit bars 904 can be synchronously expanded outward and contact the inner wall of the diaphragm spring, so as to support and limit all the diaphragm springs connected to the outer surface of the mounting tube 8. After completing the limiting work of the diaphragm spring, the transfer assembly 4 is pushed so that the mounting tube 8 and the diaphragm spring can be sent into the annealing furnace body 1.

[0044] When the annealing furnace body 1 is working, the motor 7 is controlled to work so that the output shaft of the motor 7 drives the driving gear 502 to rotate through the fixed bracket 501, and the driving gear 502 drives multiple driven gears 503 to rotate synchronously. The driven gear 503 drives the mounting tube 8 to rotate through the rotating shaft 505, and the mounting tube 8 drives the multiple diaphragm springs to rotate, so that the diaphragm springs are evenly heated. The multiple driven gears 503 can revolve around the driving gear 502 during the rotation process. At the same time, the driven gear 503 drives the multiple diaphragm springs to rotate around the inside of the annealing furnace body 1 through the rotating shaft 505 and the mounting tube 8, and the continuously rotating diaphragm springs can be evenly heated.

[0045] By operating the two handles outside the furnace cover 3, the furnace cover 3 can drive the transfer assembly 4 to move, and the multiple moving wheels 402 at the bottom of the transfer assembly 4 can roll, and the furnace cover 3 drives the fixed gear ring 11 and the multiple mounting tubes 8 to move out of the annealing furnace body 1, and then adjust the angle of the transfer assembly 4 to make the annealed diaphragm spring completely exposed to the outside, and when removing the diaphragm spring, the handle 906 is adjusted in the reverse direction to make the handle 906 drive the screw rod 901 to rotate, and the two nuts 902 outside the screw rod 901 move away from each other and pull the support rod 903, and the support rod 903 drives the limit bar 904 to approach the mounting tube 8, so that the locking state of the diaphragm spring by the limit bar 904 can be released, and the diaphragm spring can be completely removed by pushing the diaphragm spring from the end of the mounting tube 8.
