Description

Technical Field

[0001] This invention relates to the field of heat treatment equipment, specifically a drum centrifugal screw continuous heat treatment feeder. Background Technology

[0002] After the raw materials for screws (usually wire) are formed through cold heading, thread rolling and other shaping processes, although the shape is achieved, the internal crystal structure contains internal stress and the strength is not high enough, especially failing to meet the requirements of high-strength bolts. In production, small standard parts such as screws generally need to undergo heat treatment such as quenching and tempering to improve the screw's strength and hardness, obtain good toughness and plasticity, eliminate internal stress, and stabilize dimensions. At this time, a screw continuous heat treatment feeder is needed to heat treat and feed the screws.

[0003] In practical use, existing continuous screw heat treatment feeders typically load a large number of screws into a basket or tray and then place the entire batch into the heating furnace and cooling medium. The screws located in the center of the basket and those at the edges experience significant differences in heating and cooling rates, resulting in uneven metallographic structure and hardness. This affects the heat treatment effect to some extent. Furthermore, the screws are easily stuck together or deformed due to contact and compression at high temperatures, which also affects subsequent use. Therefore, there is an urgent need to improve the technology of the continuous screw heat treatment feeder structure to perfect this equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a continuous heat treatment screw feeder using a centrifugal drum. Through the continuous rotation of the feeding preheating section drum, the high-temperature homogenizing section drum, and the quenching and cooling section drum, combined with the conveying action of the internal spiral blades, continuous and automated feeding of screws during the heat treatment process is achieved, effectively improving processing efficiency. Simultaneously, the transmission mechanism drives the stirring paddle to rotate, further dispersing the material and preventing screws from sticking together in the high-temperature section. Furthermore, the spray mechanism within the quenching and cooling section drum provides continuous and uniform spray cooling of the screws, greatly improving the uniformity and efficiency of quenching and cooling, thus solving the problems currently existing in the market as described in the background art.

[0007] Preferably, a drive motor is mounted on the top of the base, and a transmission shaft is fixedly connected to the output end of the drive motor. Two first cylindrical gears and one second cylindrical gear are fixedly connected to the outer end of the transmission shaft. The two first cylindrical gears are located below the feeding preheating section roller and the quenching cooling section roller, respectively. The second cylindrical gear is located below the high-temperature soaking section roller. A third cylindrical gear is fixedly connected to the outer end of both the feeding preheating section roller and the quenching cooling section roller. The third cylindrical gear is meshed with the first cylindrical gear. A fourth cylindrical gear is fixedly connected to the outer end of the high-temperature soaking section roller. The fourth cylindrical gear is meshed with the second cylindrical gear.

[0008] Preferably, the size of the first cylindrical gear is smaller than that of the second cylindrical gear, and the size of the fourth cylindrical gear is smaller than that of the third cylindrical gear.

[0009] Preferably, the drive shaft passes through the support frame on the left side of the top of the base and is rotatably connected to the support frame. A first bevel gear is fixedly connected to the end of the drive shaft. A rotating shaft is rotatably connected to the top of the base. A second bevel gear is fixedly connected to the outer end of the rotating shaft. The second bevel gear meshes with the first bevel gear. An installation groove is provided inside the connecting shaft. A driving wheel and a driven wheel are rotatably connected inside the installation groove. A conveyor belt is sleeved on the outside of the driving wheel and the driven wheel. The rotating shaft extends into the interior of the connecting shaft and is rotatably connected to the connecting shaft. The rotating shaft is connected to the driving wheel.

[0010] Preferably, there are multiple driven wheels, and the number of driven wheels is the same as the number of stirring paddles.

[0011] Preferably, a first sleeve is fitted around the outer middle of the quenching and cooling section roller, and a second sleeve is connected to both ends of the first sleeve. The second sleeve is also fitted around the outer side of the quenching and cooling section roller. A first annular groove is formed inside the first sleeve, and a second annular groove is formed inside the second sleeve. A water outlet pipe is connected to the outer end of the first sleeve. Multiple through holes are formed at the outer end of the quenching and cooling section roller. A water inlet pipe is connected to the outer end of the second sleeve. A spray channel is formed between the position of the quenching and cooling section roller corresponding to the second sleeve and the spiral blade.

[0012] Preferably, a sealing gasket is provided at the contact points between the first sleeve, the second sleeve and the quenching and cooling section roller.

[0013] Preferably, the through hole is located inside the first sleeve.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention achieves continuous and automated feeding of screws during heat treatment by continuously rotating the feeding preheating section drum, the high-temperature homogenizing section drum, and the quenching and cooling section drum, in conjunction with the conveying action of the internal spiral blades. This effectively improves processing efficiency. Simultaneously, the screws are dispersed and continuously tumbled within the drums as they rotate, avoiding the uneven heating and cooling problems caused by the accumulation of material in traditional baskets. This ensures the uniformity and stability of heat treatment quality. Furthermore, the transmission mechanism drives the stirring paddle to rotate, further dispersing the material and preventing screws from sticking together in the high-temperature section, thus improving the product qualification rate. The spray mechanism within the quenching and cooling section drum provides continuous and uniform spray cooling to the screws, greatly improving the uniformity and efficiency of quenching and cooling, and facilitating overall use.

[0015] This invention, through the setting of a transmission mechanism, uses a controller to control the operation of the drive motor. The drive motor drives the transmission shaft to rotate, and the rotation of the first and second cylindrical gears drives the rotation of the third and fourth cylindrical gears. This, in turn, drives the preheating section drum, the high-temperature soaking section drum, and the quenching and cooling section drum to rotate, thus centrifugally dispersing the screws. The rotation of the transmission shaft drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate. The second bevel gear drives the drive wheel to rotate via a rotating shaft, which in turn drives the driven wheel to rotate via a conveyor belt. This drives the stirring paddle to rotate around its own axis, enabling it to more actively and powerfully agitate the screws in the feed and discharge cylinders. This effectively prevents material from accumulating at the inlet or sticking at the outlet due to high-temperature residual heat, ensuring smooth flow and dispersion of the material.

[0016] This invention utilizes a spray mechanism. A first sleeve and a second sleeve, along with their internal first and second annular grooves, surround the quenching and cooling section drum. These, combined with an inlet pipe, an outlet pipe, and through holes and spray channels on the drum wall, create a highly efficient and uniform closed-loop cooling system. The cooling medium enters the second annular groove through the inlet pipe and is then evenly sprayed into the drum through the spray channels to quench the screws. The heated medium then flows back into the first annular groove through the through holes and is finally discharged or circulated through the outlet pipe. A sealing gasket ensures a tight seal at the rotating connection between the sleeve and the drum, preventing leakage. This mechanism achieves comprehensive, continuous, and uniform spray cooling of the moving screws, significantly improving the uniformity and efficiency of quenching and cooling.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0020] Please see Figures 1 to 6 This invention provides a technical solution: a centrifugal roller screw continuous heat treatment feeder, comprising a base 1, with two support frames 2 fixedly connected to the top of the base 1. A feed cylinder 3 is mounted on the left support frame 2 at the top of the base 1, and a discharge cylinder 4 is mounted on the right support frame 2 at the top of the base 1. Between the feed cylinder 3 and the discharge cylinder 4 are a feed preheating section roller 5, a high-temperature homogenizing section roller 6, and a quenching and cooling section roller 7. The cylinder 7 and the discharge cylinder 4 are rotatably connected to each other. The feeding preheating section roller 5 is located in the preheating area inside the heat treatment furnace, and the high temperature homogenizing section roller 6 is located in the high temperature area inside the heat treatment furnace. The top of the feeding cylinder 3 is provided with a feeding port 14, and the bottom of the discharge cylinder 4 is provided with a discharge port 15. The feeding preheating section roller 5, the high temperature homogenizing section roller 6 and the quenching and cooling section roller 7 are provided with a rotating mechanism. The rotating mechanism controls the feeding preheating section roller 5, the high temperature homogenizing section roller 6 and the quenching and cooling section roller 7 to rotate. The feed inlet 14 is provided with a first guide plate 16 at an angle, and the discharge cylinder 4 is provided with a second guide plate 17 at an angle on the inner top wall. The feed preheating section drum 5, the high temperature homogenizing section drum 6, and the quenching and cooling section drum 7 are all fixedly connected with spiral blades 18. The feed cylinder 3 and the discharge cylinder 4 are connected by a connecting shaft 22. The connecting shaft 22 is provided with an agitator 27 on the outside. The connecting shaft 22 drives the agitator 27 to rotate through a transmission mechanism. The quenching and cooling section drum 7 is provided with a cooling spray mechanism to cool the material in the quenching and cooling section drum 7.

[0021] By continuously rotating the feeding preheating section drum 5, the high-temperature homogenizing section drum 6, and the quenching cooling section drum 7, in conjunction with the conveying action of the internal spiral blades 18, continuous and automated feeding of screws during the heat treatment process is achieved, effectively improving processing efficiency. At the same time, the screws are dispersed and conveyed within the drums and continuously tumbled as the drums rotate, avoiding the uneven heating and cooling problems caused by the accumulation of material in traditional baskets, ensuring the uniformity and stability of heat treatment quality. In addition, the transmission mechanism drives the stirring paddle 27 to rotate, which can further disperse the material and prevent the screws from sticking together in the high-temperature section, improving the product qualification rate. Furthermore, the spray mechanism inside the quenching cooling section drum 7 can continuously and uniformly spray and cool the screws, greatly improving the uniformity and efficiency of quenching cooling and facilitating overall use.

[0022] Please see Figures 1 to 6 The lead of the spiral blades 18 in the high-temperature heating section drum 6 is greater than that in the quenching and cooling section drum 7. By setting a larger lead in the high-temperature heating section drum 6, the tumbling is enhanced. By setting a smaller lead in the quenching and cooling section drum 7, the cooling time can be extended. A drive motor 8 is mounted on the top of the base 1. The output end of the drive motor 8 is fixedly connected to a transmission shaft 9. Two first cylindrical gears 10 and one second cylindrical gear 11 are fixedly connected to the outer end of the transmission shaft 9. The two first cylindrical gears 10 are located below the feeding preheating section drum 5 and the quenching and cooling section drum 7, respectively. The second cylindrical gear 11 is located below the high-temperature heating section drum 6. A third cylindrical gear 12 is fixedly connected to the outer end of both the feeding preheating section drum 5 and the quenching and cooling section drum 7. The third cylindrical gear 12 and the first cylindrical gear 10 are meshed together. A fourth cylindrical gear 13 is fixedly connected to the outer end of the high-temperature heating section drum 6. The fourth cylindrical gear 13 and the second cylindrical gear 11 are meshed together.

[0023] When the drive motor 8 is controlled by the controller, the drive motor 8 can drive the transmission shaft 9 to rotate. The rotation of the first cylindrical gear 10 and the second cylindrical gear 11 can drive the third cylindrical gear 12 and the fourth cylindrical gear 13 to rotate, thereby driving the feeding preheating section roller 5, the high temperature heating section roller 6 and the quenching cooling section roller 7 to rotate to centrifugally disperse the screws.

[0024] Please see Figures 1 to 6 The size of the first cylindrical gear 10 is smaller than that of the second cylindrical gear 11, and the size of the fourth cylindrical gear 13 is smaller than that of the third cylindrical gear 12. By setting the size of the fourth cylindrical gear 13 to be smaller than that of the third cylindrical gear 12, the rotation speed of the high-temperature heating section roller 6 can be greater than that of the feeding preheating section roller 5 and the quenching cooling section roller 7, further increasing the tumbling speed. The drive shaft 9 passes through the support frame 2 on the left side of the top of the base 1 and forms a rotatable connection with the support frame 2. The end of the drive shaft 9 is fixedly connected to the first bevel gear 19. The top of the base 1 is rotatably connected to the rotating shaft 20. The outer end of the rotating shaft 20 is fixedly connected to the second bevel gear 21. The second bevel gear 21 meshes with the first bevel gear 19. The interior of the connecting shaft 22 is provided with an installation groove 23. The interior of the installation groove 23 is rotatably connected to the driving wheel 24 and the driven wheel 25. The exterior of the driving wheel 24 and the driven wheel 25 is sleeved with a conveyor belt 26. The rotating shaft 20 extends into the interior of the connecting shaft 22 and forms a rotatable connection with the connecting shaft 22. The rotating shaft 20 is connected to the driving wheel 24.

[0025] The drive motor 8 drives the transmission shaft 9 to rotate, which in turn drives the second bevel gear 21 to rotate. The second bevel gear 21 drives the drive wheel 24 to rotate through the rotating shaft 20, which in turn drives the driven wheel 25 to rotate through the conveyor belt 26, driving the stirring paddle 27 to rotate around its own axis, which can more actively and powerfully turn the screws in the feed cylinder 3 and the discharge cylinder 4.

[0026] Please see Figures 1 to 6 Multiple driven wheels 25 are provided, and the number of driven wheels 25 is the same as the number of stirring paddles 27. A first sleeve 28 is sleeved in the middle of the outside of the quenching and cooling section drum 7. The two ends of the first sleeve 28 are connected to the second sleeve 29, which is also sleeved on the outside of the quenching and cooling section drum 7. A first annular groove 30 is opened inside the first sleeve 28, and a second annular groove 31 is opened inside the second sleeve 29. A water outlet pipe 32 is connected to the outer end of the first sleeve 28. Multiple through holes 34 are opened at the outer end of the quenching and cooling section drum 7. A water inlet pipe 35 is connected to the outer end of the second sleeve 29. A spray channel 33 is opened between the position of the quenching and cooling section drum 7 corresponding to the second sleeve 29 and the spiral blade 18.

[0027] A highly efficient and uniform closed-loop cooling system is formed by the first sleeve 28 and the second sleeve 29 surrounding the quenching and cooling section drum 7, along with the first annular groove 30 and the second annular groove 31 inside them, in conjunction with the water inlet pipe 35, the water outlet pipe 32, and the through holes 34 and spray channels 33 on the drum wall. The cooling medium enters the second annular groove 31 from the water inlet pipe 35, and is evenly sprayed into the inside of the drum through the spray channels 33 to quench the screws. The medium that has absorbed heat then flows into the first annular groove 30 through the through holes 34, and is finally discharged or circulated through the water outlet pipe 32.

[0028] Please see Figures 1 to 6 A sealing gasket 36 is provided at the contact point between the first sleeve 28, the second sleeve 29 and the quenching and cooling section roller 7, and the through hole 34 is located inside the first sleeve 28.

[0029] Working principle: When using this centrifugal screw continuous heat treatment feeder, the screws are first fed into the feed inlet 14 and guided into the feed cylinder 3 by the first guide plate 16. The drive motor 8 is started, and the power is transmitted to the rotating mechanism and the transmission mechanism through the transmission shaft 9. On one hand, the first cylindrical gear 10 and the second cylindrical gear 11 on the transmission shaft 9 drive the third cylindrical gear 12 and the fourth cylindrical gear 13 that mesh with them, thereby driving the feed preheating section drum 5, the high temperature homogenizing section drum 6 and the quenching and cooling section drum 7 to start rotating. The spiral blades 18 inside the drum rotate accordingly, pushing the screws from the feed preheating section drum 5 to the high temperature homogenizing section drum 6, and then to the quenching and cooling section drum 7 for continuous feeding. During this process, the screws are continuously turned over and scattered to achieve uniform heating and cooling. Meanwhile, the first bevel gear 19 at the end of the drive shaft 9 meshes with the second bevel gear 21 to change the direction of power and drive the rotating shaft 20 to rotate. The rotating shaft 20 transmits power to the mounting groove 23 in the connecting shaft 22, which drives multiple driven wheels 25 to rotate through the drive wheel 24 and the conveyor belt 26. This causes the stirring paddle 27 connected to each driven wheel 25 to rotate. In the feed cylinder 3 and the discharge cylinder 4, the rotating stirring paddle 27 further disperses and flips the screws to prevent blockage or adhesion. When the screw is conveyed to the quenching and cooling section drum 7, the cooling spray mechanism is activated. The cooling medium is pumped from the inlet pipe 35 into the second annular groove 31 inside the second sleeve 29, and then evenly sprayed into the interior of the high-speed rotating drum through the spray channel 33, making full contact with the high-temperature screw to achieve rapid and uniform quenching and cooling. The medium that has absorbed heat passes through the through hole 34 on the drum wall and collects in the first annular groove 30 of the first sleeve 28, and is finally discharged from the outlet pipe 32. The system realizes the continuous and automated operation of screw heat treatment, ensuring the uniformity and stability of the treatment quality.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
