Description

Technical Field

[0001] This utility model relates to the field of steel ball quenching heat treatment technology, specifically a steel ball quenching heat treatment device. Background Technology

[0002] Quenching is a heat treatment process. For steel, quenching involves heating the steel to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), holding it at that temperature for a period of time to achieve complete or partial austenitization, and then rapidly cooling it at a rate greater than the critical cooling rate to below Ms (or isothermally near Ms) to induce a martensitic (or bainitic) transformation. Quenching is also commonly used to describe solution treatment or heat treatment processes involving rapid cooling in materials such as aluminum alloys, copper alloys, titanium alloys, and tempered glass.

[0003] A quenching heat treatment device for steel ball processing, patent number CN220846203U, includes a quenching box with a feed inlet on one side of the top and a discharge outlet on the side of the top away from the feed inlet. The quenching box has a filter mechanism inside and a discharge box above the filter mechanism. The top of the quenching box has a lifting mechanism and an air outlet connected to an external fan.

[0004] However, research has shown that existing steel ball quenching heat treatment equipment still has the following drawbacks:

[0005] Currently, the common practice in the market for quenching steel balls is to remove the previously quenched steel balls before quenching the next batch. Adding and removing steel balls are done in separate steps, which is time-consuming and reduces quenching efficiency. Therefore, it is necessary to optimize a steel ball quenching heat treatment device through technological innovation and design optimization. Utility Model Content

[0006] Currently, in the market, when quenching steel balls, the previously quenched steel balls are usually removed before the next batch is quenched. Adding and removing steel balls are done in separate steps, which is time-consuming and reduces quenching efficiency. To solve the above problems, this application provides a steel ball quenching heat treatment device. By setting a rotating frame to drive the material frame and fixed plate to rotate, the steel balls to be quenched can be put into the coolant while the previously quenched steel balls are taken out. This eliminates the need for separate steps and improves the quenching efficiency. By setting a limiting mechanism, the material frame can be limited and supported, avoiding excessive impact force on the material frame when adding steel balls, which could cause the material frame to shake and damage the motor, thus extending the service life of the motor.

[0007] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0008] A steel ball quenching heat treatment apparatus, comprising:

[0009] The box body has an arc-shaped groove inside, a rotating frame is installed inside the arc-shaped groove, a material frame is fixed on the rotating frame, and a motor that can drive the rotating frame to rotate is fixed on one side of the box body.

[0010] A limiting mechanism is located on one side of the box and is used to limit the material frame.

[0011] In one possible implementation, a discharge port is provided on one side of the box, and a discharge plate is fixed at the discharge port to facilitate the discharge of steel balls.

[0012] In one possible implementation, the rotating frame includes a cylinder inside the housing, both ends of which are rotatably connected to the housing. A cylinder is fitted around the outside of the cylinder, and a connecting rod is provided between the cylinder and the cylinder. Both ends of the connecting rod are fixedly connected to the cylinder and the cylinder, respectively. The output end of the motor is fixedly connected to the cylinder. The motor drives the rotating frame to rotate, and the rotating frame drives the material frame to rotate, which facilitates the placement of steel balls from the material frame into the arc-shaped groove.

[0013] In one possible implementation, the cylinder is fixedly connected to the material frame, and the material frame has several circular holes II. The coolant in the arc-shaped groove will pass through the circular holes II, which facilitates the movement of the material frame in the arc-shaped groove.

[0014] In one possible implementation, a fixing plate is fixed to the outside of the cylinder. The fixing plate has a circular hole and the surface of the fixing plate is inclined. The fixing plate rotates with the cylinder, which facilitates the ejection of the cooled steel ball from the arc groove.

[0015] In one possible implementation, the limiting mechanism includes a limiting groove on the material frame, a U-shaped plate fixed to the side of the box, a limiting post passing through the U-shaped plate, a pulling block fixed to one end of the limiting post away from the box, the other end of the limiting post passing through the box, a baffle fixed to the limiting post, and a spring sleeved on the outside of the limiting post between the baffle and the U-shaped plate. The spring is in a compressed state, and the spring will move the limiting post into the limiting groove through the baffle, thereby limiting and supporting the material frame, and preventing excessive impact force on the material frame when steel balls are added into the material frame, which would cause the material frame to shake and thus damage the motor.

[0016] In one possible implementation, the limiting post can be inserted into the slot and can slide on the U-shaped plate and the box body to facilitate limiting the material frame.

[0017] In one possible implementation, the housing is provided with an inlet pipe and a drain pipe, both of which penetrate the housing. Solenoid valves are installed on both the inlet pipe and the drain pipe to facilitate the replacement of the coolant inside the housing.

[0018] In summary, this utility model has at least one of the following beneficial technical effects:

[0019] 1. By setting a rotating frame to drive the material frame and fixed plate to rotate, the steel balls that need to be quenched can be put into the coolant at the same time as the previous batch of quenched steel balls are taken out, eliminating the need for step-by-step operation and improving the efficiency of quenching.

[0020] 2. By setting a limiting mechanism, the material frame can be limited and supported, avoiding excessive impact force on the material frame when steel balls are added into the material frame, which would cause the material frame to shake and damage the motor, thus extending the service life of the motor.

Detailed Implementation

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The instrument placement rack involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] This embodiment describes the specific structure of a steel ball quenching heat treatment device, which can be referred to in detail below. Figures 1-3 As shown, a steel ball quenching heat treatment apparatus includes:

[0027] Box 1, with an arc-shaped groove 15 inside the box 1, a rotating frame inside the arc-shaped groove 15, a material frame 3 fixed on the rotating frame, and a motor 7 that can drive the rotating frame to rotate fixed on one side of the box 1.

[0028] The limiting mechanism is located on one side of the box 1 and is used to limit the material frame 3.

[0029] Currently, when quenching steel balls, the process typically involves removing the previously quenched balls before quenching the next batch. Adding and removing steel balls are done in separate steps, which is quite time-consuming.

[0030] It is worth noting that a discharge port 13 is provided on one side of the box body 1, and a discharge plate 8 is fixed at the discharge port 13 to facilitate the discharge of steel balls. The rotating frame includes a cylinder 11 inside the box body 1, with both ends of the cylinder 11 rotatably connected to the box body 1. A cylinder 4 is fitted around the cylinder 11, and a connecting rod 14 is provided between the cylinder 4 and the cylinder 11. The two ends of the connecting rod 14 are fixedly connected to the cylinder 11 and the cylinder 4, respectively. The output end of the motor 7 is fixedly connected to the cylinder 11, and the motor 7 drives the rotating frame to rotate. The material frame 3 rotates to facilitate the placement of steel balls into the arc-shaped groove 15. The cylinder 4 is fixedly connected to the material frame 3. Several circular holes 12 are provided on the material frame 3. The coolant in the arc-shaped groove 15 will pass through the circular holes 12 to facilitate the movement of the material frame 3 within the arc-shaped groove 15. A fixing plate 5 is fixed to the outside of the cylinder 4. A circular hole 6 is provided on the fixing plate 5. The surface of the fixing plate 5 is set at an angle. The fixing plate 5 rotates with the cylinder 4 to facilitate the ejection of the cooled steel balls from the arc-shaped groove 15.

[0031] When the steel ball is poured into the material frame 3, the steel ball will impact the material frame 3. At this time, the material frame 3 will cause the rotating frame to shake. The rotating frame may damage the output shaft of the motor 7.

[0032] The limiting mechanism includes a limiting groove 19 on the material frame 3, a U-shaped plate 2 fixed to the side of the box 1, a limiting post 20 passing through the U-shaped plate 2, a pulling block 16 fixed to one end of the limiting post 20 away from the box 1, and the other end of the limiting post 20 passing through the box 1. A baffle 18 is fixed to the limiting post 20, and a spring 17 is sleeved on the outside of the limiting post 20 between the baffle 18 and the U-shaped plate 2. The spring 17 is in a compressed state, and the spring 17 will move the limiting post 20 to insert into the limiting groove 19 through the baffle 18, thereby limiting and supporting the material frame 3, and avoiding excessive impact force on the material frame 3 when steel balls are added into the material frame 3, which would cause the material frame 3 to shake and damage the motor 7. The limiting post 20 can be inserted into the slot and can slide on the U-shaped plate 2 and the box 1 to facilitate limiting the material frame 3.

[0033] In addition, the housing 1 is equipped with a water inlet pipe 9 and a drain pipe 10, both of which pass through the housing 1. Solenoid valves are installed on both the water inlet pipe 9 and the drain pipe 10 to facilitate the replacement of the coolant in the housing 1.

[0034] When the workers need to quench the steel balls, they first put the steel balls to be quenched into the material frame 3, pull the limiting post 20 so that the limiting post 20 moves out of the limiting groove 19. The limiting post 20 will drive the baffle 18 to squeeze the spring 17, and start the motor 7. The motor 7 drives the material frame 3 and the fixed plate 5 to rotate through the rotating frame. As the material frame 3 and the fixed plate 5 rotate, the fixed plate 5 will push the steel balls that have been quenched in the arc groove 15 out of the discharge port 13. The steel balls that need to be quenched in the material frame 3 will remain in the arc groove 15 for quenching. When the material frame 3 rotates to the point where the limiting groove 19 is aligned with the limiting post 20, the limiting post 20 is released. Under the action of the spring 17, the limiting post 20 will insert into the limiting groove 19, thereby limiting the material frame 3.

[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
