Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ball cage cooling, in particular to a high-temperature ball cage cooling device. Background Art
[0002] A normalizing furnace is a type of heat treatment equipment. Its primary function is to heat metal materials above their critical temperature, typically within the fully austenitizing temperature range, and then cool them in air. This process is called normalizing. Its purpose is to improve the metal's microstructure and mechanical properties.
[0003] After the ball cage parts are forged by a forging press, the temperature is generally above 800 degrees. Usually, the hot workpieces are manually placed in an iron bucket using tools such as pliers to collect them and cool them naturally. Then, they are moved into a normalizing furnace for reheating and cooling before being put into the next shot blasting process. In the existing technology, the ball cage parts are manually placed in an iron bucket using tools such as pliers to collect them and cool them naturally. In this process, the accumulation of ball cage parts leads to heat accumulation and uneven heat dissipation, which causes internal stress and deformation in the workpiece, thereby reducing the quality of the workpiece. If water cooling or oil cooling is used, the cooling rate will be greatly accelerated due to uneven cooling. Parts of the workpiece may be converted into martensite structure. The production of martensite will cause the workpiece volume to increase and produce local deformation, thereby reducing the quality of the workpiece. Utility Model Content

When the telescopic rod rotates, the fan blades follow the rotation to generate air disturbance and accelerate the heat dissipation rate of the workpiece placed on the disc.
[0006] Furthermore, a plurality of positioning grooves distributed in an array are provided on the top of the disc, and each positioning groove has a corresponding ventilation hole.

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0023] See also Figure 1-Figure 3 A high-temperature ball cage cooling device includes: a fixed box 1, a telescopic rod 3 is rotatably arranged in the fixed box 1, a disc 2 is fixedly sleeved on each telescopic section of the telescopic rod 3, and a fan blade 4 is fixedly connected to the bottom of the disc 2 and arranged coaxially with the disc 2. A plurality of ventilation holes 23 are opened on the disc 2. When the telescopic rod 3 rotates, the fan blade 4 rotates with it to generate air disturbance and accelerate the heat dissipation rate of the workpiece placed on the disc 2.
[0024] Specifically, a ring 21 is fixedly connected to the outer edge of the disc 2 to enhance the aesthetics of the device. The fan blade 4 is fixedly sleeved on the outside of the telescopic rod 3, and its top is fixedly connected to the bottom of the disc 2. However, there is still a vertical distance of 5 cm between the disc 2 and the fan blade 4 to ensure that the airflow disturbed by the fan blade 4 can pass through the ventilation hole 23. The ball cage is placed in the positioning groove 22 in an inverted manner. The array-distributed positioning groove 22 makes the ball cage placed therein also distributed in an array, ensuring that the heat dissipation space of each ball cage is the same.
[0025] The utility model fixes the fan blades 4 at the bottom of the disc 2 and rotates the telescopic rod 3, so that the workpieces on the disc 2 are always in motion, so that each workpiece can be evenly exposed to the natural wind and can dissipate heat more evenly. In the process of rotation of the telescopic rod 3, the fan blades 4 follow the rotation, so that the fan blades 4 disturb the surrounding air, and then accelerate the air flow rate around the disc 2, so that the heat exchange efficiency between the workpiece and the air is accelerated, and its heat dissipation efficiency is further improved.
[0026] In the present invention, a disc 2 for placing workpieces is fixedly sleeved on each telescopic section of the telescopic rod 3, so that when no workpiece is placed on the disc 2, the telescopic rod 3 can be folded to achieve the purpose of stacking multiple discs 2 together, thereby reducing the volume of the equipment and facilitating transportation and storage.
[0027] Furthermore, a plurality of positioning grooves 22 distributed in an array are provided on the top of the disc 2 , and each positioning groove 22 has a corresponding ventilation hole 23 .
[0028] Specifically, the direction of the airflow disturbed by the fan blades 4 is from bottom to top. By opening ventilation holes 23 in the positioning grooves 22, external cold air can enter the inverted ball cage through the ventilation holes 23, so that the ball cage can dissipate heat evenly from both the inside and outside.
[0029] Furthermore, the bottom of the telescopic rod 3 is connected to the top of the fixed box 1 through a thrust bearing 8, the bottom of the lower gasket of the thrust bearing 8 is fixedly connected to the top of the fixed box 1, and the top of the upper gasket of the thrust bearing 8 is fixedly connected to the bottom of the telescopic rod 3. A motor 6 is fixedly installed in the fixed box 1, and the output shaft of the motor 6 is fixedly connected to the bottom of the telescopic rod 3 after passing through the thrust bearing 8.
[0030] Specifically, the thrust bearing 8 can withstand a large axial pressure, so the thrust bearing 8 is used here, and the output shaft of the motor 6 is directly fixedly connected to the bottom of the telescopic rod 3, so that the motor 6 can directly drive the telescopic rod 3 to rotate, and under the action of the upper and lower gaskets of the thrust bearing 8, the sliding friction between the bottom of the telescopic rod 3 and the top of the fixed box 1 is converted into rolling friction inside the thrust bearing 8, thereby greatly reducing the kinetic energy loss and making the rotation of the telescopic rod 3 more stable.
[0031] Furthermore, a plurality of universal locking wheels 5 with a self-locking function are fixedly connected to the bottom of the fixed box 1 , and a tether hook 7 is fixedly connected to one side of the fixed box 1 .
[0032] Specifically, by installing four universal locking wheels 5 with self-locking function at the bottom of the fixed box 1, the movement and fixed position placement of the fixed box 1 can be facilitated. A tether hook 7 is fixedly connected to one side of the fixed box 1, which makes it convenient for the operator to use an iron hook to hook the tether hook 7 or a rope to be tied to the tether hook 7 to pull and transfer the fixed box 1.
[0033] In this utility model, reference is made to Figures 1 to 3First, stretch the telescopic rod 3 in the retracted state as needed, then put the normalized ball cage upside down in the positioning groove 22, and adopt a symmetrical placement method during the placement process, that is, when placing multiple ball cages on the disc 2, try to ensure that the weight on the disc 2 is evenly distributed. Finally, start the motor 6. The motor 6 can be used with a reducer to make the telescopic rod 3 rotate slowly to ensure that the ball cage can be evenly cooled. According to the different materials of the ball cage, different speeds can be used for heat dissipation and cooling to improve the quality of the ball cage.
[0034] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
