Description

[0001] Steel ball quenching pool Technical Field

[0002] The utility model belongs to the field of heat treatment equipment, in particular to a steel ball quenching pool. Background Art

[0003] Obliquely rolled steel balls are a type of rolled wear-resistant steel ball product made using an oblique rolling process. The heated round steel bars are fed into the oblique rolling mill through a conveying device. The oblique rolling mill drives the rollers to rotate, and the rollers obliquely roll the high-temperature round steel into multiple steel balls. The cooling of the steel ball in the quenching medium needs to go through three stages, namely the steam film stage → boiling stage → convection stage. The cooling rate in the steam film stage is slow, and the boiling stage has the highest cooling rate. The purpose of steel ball quenching is to cool at a higher cooling rate to obtain a martensitic structure with high hardness and high wear resistance. The steel ball quenching needs to shorten the steam film stage as much as possible, enter the boiling stage as soon as possible, and speed up the cooling rate to achieve the quenching purpose.

[0004] The water spray outlet of the raceway in the quenching pool of the existing φ80 steel ball production line is located too high and faces the top of the quenching pool. The water flow cannot be directly sprayed onto the surface of the steel ball on the raceway, which cannot quickly destroy the stability of the steam film on the surface of the steel ball, shorten the time of the steam film stage, and cannot quickly enter the boiling stage, resulting in insufficient quenching cooling speed of the steel ball, low hardness after quenching, non-martensitic structure generation, and reduced wear resistance. At the same time, the fluidity of the circulating water in the quenching pool of the existing φ80 steel ball production line is poor, resulting in low heat exchange efficiency in the quenching pool.

[0005] Therefore, improvements are now made to the problems existing in the φ80 steel ball production line, such as insufficient quenching cooling speed of steel balls and poor water fluidity in the quenching pool. Utility Model Content

A first motor 12 is provided on the upper part of the side wall of the pool body 1, and a first driving sprocket is provided at the output end of the first motor 12. The first driving sprocket is connected to the first driving sprocket through the first driving chain, and the first motor 12 is used to drive the first driving shaft to rotate.

[0036] Specifically, if Figure 1 As shown, the steel balls need to maintain continuous heat exchange during the quenching process, so the water level in the quenching pool must always be kept above the steel balls. By using the principle that hot water floats after the steel balls exchange heat with water, a portion of the boiling hot water overflows from both sides of the pool body 1 to the overflow tank 3, and the bottom surface of the overflow tank 3 is inclined toward the third drain port 19. Figure 2As shown, the water outlet of the water spray pipe 5 is positioned toward both sides of the steel ball raceway 10, so that the incoming water flow is directly sprayed onto the surface of the steel ball, reducing the stability of the steam film on the surface of the steel ball, shortening the steam film stage time, and allowing the heat exchange of the steel ball under high temperature conditions to quickly enter the boiling stage, thereby increasing the quenching cooling rate of the steel ball, thereby maximizing the acquisition of a high-hardness, high-wear-resistant martensitic metallographic structure and improving the wear resistance of the steel ball.

[0037] Specifically, Figure 4 As shown, multiple water spray pipes 5 are arranged in the length direction of the bottom plate 8, and a steel ball raceway 2 is formed between adjacent water spray pipes 5; the first motor 12 is arranged on the upper part of the side wall of the pool body 1, and drives the first driving wheel to rotate by chain transmission, thereby driving the first driven wheel and the first chain 10 to rotate, and the first chain 10 drives the ball pushing plate 6 to move along the steel ball raceway 2, thereby pushing the steel ball to move along the steel ball raceway 2. The first motor 12 drives the steel ball transmission mechanism to rotate by chain transmission, which is suitable for working conditions such as quenching pools with high temperature and high humidity.

[0038] In this embodiment, if Figure 5 and Figure 6 As shown, the steel ball quenching pool of this embodiment also includes an impeller mechanism, which is arranged in the pool body 1 and located below the steel ball transmission mechanism, including: two pairs of second bearing seats arranged at the bottom of the pool body 1, a second driving shaft and a second driven shaft connected to the second bearing seats, a pair of impellers 14 respectively arranged on the second driving shaft and the second driven shaft, and a driving mechanism for driving the second driving shaft to rotate, and the rotation direction of the impeller 14 is consistent with the movement direction of the first chain 10 in the lower layer. The second driving shaft and the second driven shaft are also respectively provided with a pair of second driven sprockets, and a second chain (not shown) is provided on the pair of second driven sprockets. The second driving shaft is also provided with a second driving sprocket, and a second motor (not shown) is provided on the upper part of the side wall of the pool body 1. The output end of the second motor is provided with a second drive sprocket, and the second drive sprocket is connected to the second driving sprocket through a second drive chain (not shown). The second motor is used to drive the second driving shaft to rotate, thereby driving the second chain to rotate.

[0039] Specifically, Figure 5 and Figure 6As shown, the impeller mechanism is arranged below the steel ball transmission mechanism, and a pair of impellers 14 are arranged on the second driving shaft and the second driven shaft respectively. The pair of impeller shafts are connected by a second chain, and the impeller 14 is driven to rotate by the second chain. The impeller 14 drives the water at the bottom of the pool body 1 to be discharged toward the second drain port 18. The second motor drives the impeller mechanism to rotate by chain transmission, which is suitable for the working conditions of high temperature and high humidity such as the quenching pool. The rotation direction of the impeller 14 is consistent with the movement direction of the first chain 10 at the bottom of the bottom plate 8, which reduces the movement resistance of the ball push plate 6 driven by the first chain at the bottom of the bottom plate 8 in the water, and further accelerates the fluidity of the water in the pool body 1, improves the heat exchange efficiency in the fire pool, and ensures the consistency of the surface hardness of the steel ball.

[0040] In this embodiment, if Figure 5 and Figure 7 As shown, the steel ball quenching tank of this embodiment also includes: a first ball guide plate 16 and a second ball guide plate 17. A ball guide groove 4 is provided above one end of the steel ball rolling mechanism. The first ball guide plate 16 is arranged at the other end of the steel ball rolling mechanism. The first ball guide plate 16 is connected to the bottom plate and is inclined toward the other end of the pool body 1. The second ball guide plate 17 is arranged between the first ball guide plate 16 and the other end of the pool body 1, and the second ball guide plate 17 is inclined toward one side wall of the pool body 1.

[0041] Specifically, Figure 7 As shown, the ball guide groove 4 includes three branches, which facilitate the steel balls to be evenly distributed into the steel ball raceway 2 of the quenching pool. An arc-shaped baffle is provided at the end of each branch of the ball guide groove 4, and the bottom of each branch end is hollowed out. The steel balls fall from the bottom into the steel ball raceway 2. The arc-shaped baffle is used to prevent the steel balls from rolling down at too high a speed and causing impact on the steel ball rolling 2.

[0042] In this embodiment, if Fig. 9 and Fig.10 As shown, the steel ball quenching tank of this embodiment also includes a chain elevator 23, which is arranged obliquely to the side wall of the pool body 1 and is arranged on the second ball guide plate 17; the chain elevator 23 includes a bracket 24 and a chain transmission mechanism 25 arranged on the bracket 24, a support plate 26 is provided along the inclined direction of the chain transmission mechanism 25, and a plurality of chain buckets 21 are provided between a pair of transmission chains of the chain transmission mechanism 25.

[0043] Specifically, Figure 5 , Fig. 9 and Fig.10As shown, the steel ball is pushed from one end of the bottom plate 8 to the other end by the ball pushing plate 6, and falls to the first ball guide plate 16. The second ball guide plate 17 is inclined toward the side wall of the pool body 1 to form a low-lying position. The steel ball falls from the first ball guide plate 16 to the low-lying position of the second ball guide plate 17. A chain hoist 23 is arranged on the second ball guide plate 17. The chain hoist 23 follows the inclined direction of the second ball guide plate 17. A chain bucket 21 is arranged on the chain hoist 23. The third motor 22 drives the chain to move through the sprocket, and drives the chain bucket 21 to move upward along the support plate 26, so as to salvage the steel ball in the low-lying part of the second ball guide plate 17. The support plate 26 between the chains can prevent the steel ball from falling, and transport the quenched steel ball to the next process.

[0044] In this embodiment, if Figure 6 As shown, the arc-shaped ball guide plate 11 is also included. The arc-shaped ball guide plate 11 is vertically arranged on the first ball guide plate 16, and the arc-shaped ball guide plate 11 is provided with a plurality of leakage holes. The arc-shaped ball baffle plate 11 guides the steel balls rolling down along the first ball guide plate 16 to fall to the low-lying part of the second ball guide plate 17, so that the chain hoist 23 can salvage the steel balls in the low-lying part. The leakage holes of the arc-shaped ball guide plate 11 facilitate the water in the pool body 1 to be discharged from the first drain port 13.

[0045] In this embodiment, a main water inlet (not shown) is provided on the side wall of the tank body to facilitate rapid water injection into the tank body 1 before production.

[0046] When the steel ball quenching pool of the utility model is used, the rolled steel balls are transported to the goal guide groove 4 by the elevator, and the goal guide groove 4 disperses the steel balls into the steel ball raceway 2 of the pool body 1, and the ball pushing plate 6 is driven by the first chain 10 to push the steel balls to move along the steel ball raceway 2. The water nozzle 7 of the water spray pipe 5 is positioned toward both sides of the steel ball raceway 2, so that the incoming water flow is directly sprayed on the surface of the steel balls, reducing the stability of the steam film on the surface of the steel balls, shortening the steam film stage time, and allowing the heat exchange of the steel balls under high temperature conditions to quickly enter the boiling stage. By utilizing the principle that hot water floats after the steel balls exchange heat with water, a part of the boiling hot water overflows from both sides of the pool body 1 to the overflow trough 3, and the bottom surface of the overflow trough 3 is inclined toward the third drain port 18, which is convenient for discharging hot water.

[0047] The impeller mechanism at the bottom of the pool body 1 can drive the water at the bottom of the pool body 1 to flow toward the second water outlet. At the same time, the rotation direction of the impeller 14 is consistent with the movement direction of the first chain 10 at the bottom of the bottom plate 1. Since the ball pusher plate 6 has a certain resistance when moving underwater, the impeller 14 guides the water flow at the bottom of the pool body 1 to reduce the movement resistance of the first chain 10, and further accelerate the fluidity of the water in the pool body 1, improve the heat exchange efficiency in the fire pool, and ensure the consistency of the surface hardness of the steel ball. Under the guidance of the first ball guide plate 16 and the arc ball guide plate 11, the quenched steel ball falls to the low-lying area of ​​the second ball guide plate 17, and the chain bucket 21 of the chain hoist 23 salvages the quenched steel ball and sends it to the next process.

[0048] The steel ball quenching pool of this embodiment can increase the quenching cooling rate of the steel balls, thereby obtaining a high-hardness, high-wear-resistant martensitic metallographic structure to the maximum extent, thereby improving the wear resistance of the steel balls.

[0049] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
