[0031] At present, heat treatment is an important process in the production process of forged steel balls, which directly determines the internal performance of the steel balls. In the production of forged steel balls in the mechanical plant, the pre-cooling + single liquid quenching heat treatment process is adopted. The forged steel balls are first cooled on the slide (in the air), and then the steel balls are introduced into the quenching device when the surface temperature of the steel balls reaches the critical point of austenite state. However, in the existing cooling process of the steel balls, there are problems of accumulation of multiple steel balls, which easily leads to uneven cooling of the steel balls, large temperature difference deviation of the steel balls entering the water, and thus the quality of the steel balls.

[0032] Therefore, the embodiments of the present application provide a steel ball temperature control device, which can improve the temperature uniformity of the steel balls and thus improve the quality of the steel balls.

[0033] In a first aspect, the embodiments of the present application provide a steel ball temperature control device. Figure 1 A schematic structural diagram of a steel ball temperature control device provided by an embodiment of the present application is shown in FIG. 1. Figure 1As shown, the steel ball temperature control device includes a temperature control box 100, a fan 400, a sensing device 500, a pushing device 200 and a turnover device 300. The temperature control box 100 is internally provided with a spiral track 120. The spiral track can be arranged on the outer wall of the rotating shaft, or can be a spiral track with a hollow structure in the middle space. The spiral track 120 can accommodate the steel balls 140 to be cooled. The passages of the spiral track 120 are respectively communicated with the inlet and outlet of the temperature control box 100. The temperature control box is provided with a baffle 110 at the inlet and a fan 400, and is provided with an outlet passage 130 at the outlet. The baffle 110 can block the steel balls 140 to be cooled from entering the temperature control box 100, and the baffle 110 can also release the steel balls 140 to be cooled into the temperature control box 100. The air outlet of the fan 400 can be arranged towards the baffle 110, and the sensing end of the sensing device 500 can be arranged towards the baffle 110. The sensing device 500 is in communication connection with the fan 400. The sensing device 500 can sense the temperature of the steel balls 140 to be cooled at the baffle 110, and transmit the sensing signal to the fan 400. The fan 400 operates under the action of the sensing signal. The pushing device 200 is arranged corresponding to the inlet of the temperature control box 100, and the turnover device 300 is arranged corresponding to the outlet passage 130 of the temperature control box 100. The steel balls 140 to be cooled roll into the spiral track 120 of the temperature control box through the pushing device 200, and after the steel balls 140 to be cooled pass through the spiral track 120, they roll out from the outlet passage 130 of the temperature control box and enter the turnover device 300. The turnover device 300 turns over so that the steel balls 140 to be cooled roll out of the turnover device 300. After the steel balls 140 to be cooled pass through the pushing device 200, they stop at the baffle 110 of the temperature control box. The steel balls 140 to be cooled at the baffle 110 of the temperature control box are air-cooled by the fan 400 to complete the first cooling process. After the steel balls 140 to be cooled enter the spiral track 120 of the temperature control box, air cooling is performed by controlling the spiral track to run at a low speed to complete the second cooling process. The combination of air cooling and air cooling can make the surface temperature of the steel ball uniform, thereby improving the quality of the steel ball.

[0034] The steel ball temperature control device provided by the embodiment of the present application can realize uniform cooling of the temperature of a single steel ball by controlling the first cooling process of a single steel ball at the baffle of the temperature control box and the second cooling process of the steel ball through the spiral track of the temperature control box. Independent cooling of a single steel ball can avoid the connection of high-temperature steel balls in front and back, improve the uniformity of the temperature of the steel ball, and thereby improve the quality of the steel ball.

[0035] For example, the control terminal is in communication connection with the temperature control device of the steel ball, and the control terminal controls the single steel ball 140 to be cooled to stop at the baffle 110 of the temperature control box through the pushing device 200. The sensing device 500 senses the surface temperature of the steel ball 140 to be cooled and transmits the surface temperature signal of the steel ball 140 to be cooled to the fan 400. When the signal received by the fan is that the surface temperature of the steel ball is greater than 750℃, the control terminal controls the fan 400 to start running to perform the first cooling treatment on the steel ball 140 to be cooled at the baffle 110. When the signal received by the fan is that the surface temperature of the steel ball is less than or equal to 750℃, the fan 400 does not start running, and the control terminal controls the baffle 110 to be opened, and the pushing device 200 pushes the steel ball 140 to be cooled into the spiral roller 120. After the steel ball 140 to be cooled enters the spiral roller 120, the control terminal controls the spiral roller 120 to rotate at a low speed, prolongs the rolling time of the steel ball 140 to be cooled in the spiral roller 120, and further prolongs the heat dissipation time of the steel ball 140 to be cooled to complete the second cooling treatment on the steel ball 140 to be cooled. After the steel ball 140 to be cooled passes through the spiral roller 120 for cooling treatment, it enters the turnover device 300, and the turnover device 300 is turned over to make the steel ball 140 to be cooled roll out of the turnover device 300 and enter the quenching device. The control terminal controls only one steel ball to be cooled for cooling treatment each time, and controls the next steel ball to be cooled for cooling treatment after the current steel ball completes the two cooling treatments. Through the control of the single cooling treatment of each steel ball to be cooled, the balanced cooling of the temperature of the single steel ball is realized, the high-temperature steel balls are avoided to be connected in sequence, the cooling effect of the steel ball is improved, and the quality of the steel ball is further improved.

[0036] In some embodiments, the fan is used to receive the first sensing signal and the second sensing signal transmitted by the sensing device. The first sensing signal is used to represent the temperature signal of the steel ball to be cooled. The second sensing signal is used to represent whether the steel ball to be cooled exists at the baffle. The fan is started or closed according to the received first sensing signal and second sensing signal to accurately cool the steel ball to be cooled.

[0037] The sensing device can be an infrared sensor, a temperature detector or a laser scanner, for example. When the sensing device 500 senses the second sensing signal indicating that the baffle 110 is in the presence of the steel ball 140 to be cooled, the sensing device 500 transmits the second sensing signal indicating that the baffle 110 is in the presence of the steel ball 140 to be cooled to the fan, and also transmits the first sensing signal indicating the temperature of the steel ball 140 to be cooled to the fan 400. The fan 400 controls the terminal to control the operation of the fan 400 according to the received first sensing signal and second sensing signal, and performs the first cooling process on the steel ball 140 to be cooled. When the sensing device 500 senses the second sensing signal indicating that the baffle 110 is not in the presence of the steel ball 140 to be cooled, the sensing device 500 only transmits the second sensing signal indicating that the baffle 110 is not in the presence of the steel ball 140 to be cooled to the fan 400. At this time, the baffle 110 is not in the presence of the steel ball 140 to be cooled, and the fan 400 does not operate. The fan starts to operate according to the received first sensing signal and second sensing signal when it receives the signal indicating that the baffle is in the presence of the steel ball to be cooled at high temperature, and does not start to operate when it receives the signal indicating that the steel ball to be cooled is not present. The fan realizes the cooling process of the steel ball to be cooled according to different sensing signals, avoids the idling of the fan, and prolongs the service life of the control equipment.

[0038] In some embodiments, the sensing device and the fan are respectively connected in communication with the control terminal, and the baffle is used to open or close under the action of the first sensing signal and the second sensing signal. Through the setting that the control terminal is respectively connected in communication with the sensing device and the fan, the automatic cooling of the steel ball to be cooled can be realized, and the control precision of the temperature control equipment of the steel ball is improved.

[0039] Exemplarily, the sensing device 500, the fan 400, and the baffle 110 are respectively in communication connection with the control terminal. When the steel ball passes through the pushing device 200 and enters the position where the baffle 110 is located, the control terminal controls the sensing device 500 to sense the surface temperature of the steel ball 140 to be cooled. When the surface temperature of the steel ball 140 to be cooled is less than or equal to 750 DEG C, the control terminal controls the baffle 110 to be opened, and controls the fan 400 to be closed. The steel ball 140 to be cooled does not need to be cooled by the fan 400, and the baffle can directly release the steel ball 140 to be cooled to the spiral roller 120 of the temperature control box 100. When the temperature of the steel ball 140 to be cooled is greater than 750 DEG C, the control terminal controls the baffle 110 to be closed, and controls the fan 400 to be opened. The sensing device 500 senses the surface temperature of the steel ball 140 to be cooled in real time during the operation of the fan 400, until the surface temperature of the steel ball 140 to be cooled is less than or equal to 750 DEG C, and the control terminal controls the baffle 110 to be opened. When the steel ball does not pass through the pushing device and enters the position where the baffle 110 is located, the control terminal controls the baffle 110 to be closed, so as to avoid that the high-temperature steel ball directly enters the spiral roller of the temperature control box. Through the setting that the control terminal is respectively in communication connection with the sensing device, the fan, and the baffle, the temperature of the steel ball to be cooled can be monitored in real time, the automatic cooling treatment of the steel ball to be cooled can be realized, and the temperature control precision of the temperature control equipment of the steel ball is improved.

[0040] In some embodiments, the temperature control box comprises a plurality of outlets and inlets, and the plurality of outlets and inlets are respectively arranged on both sides of the spiral roller. By arranging a plurality of inlets and a plurality of outlets in the temperature control box, the cooling treatment of a plurality of steel balls to be cooled can be simultaneously performed, so as to improve the operation efficiency of the steel ball cooling.

[0041] Exemplarily, the temperature control box 100 is provided with a plurality of outlets and inlets, and the outlets and inlets are symmetrically arranged on both sides of the spiral roller 120. The plurality of inlets are arranged side by side, and the plurality of outlets are arranged side by side. A plurality of steel balls to be cooled 140 can simultaneously enter the spiral roller 120 of the temperature control box 100, and can simultaneously roll out of the spiral roller 120. Each steel ball to be cooled independently passes through the channel of the spiral roller 120. The independent cooling treatment of the steel ball to be cooled is ensured, and the operation efficiency of the steel ball cooling is improved.

[0042] In some embodiments, each inlet is correspondingly arranged with a pushing device, and each outlet is correspondingly arranged with a turnover device. Through the arrangement of the pushing device and the turnover device, the independent cooling of the steel ball to be cooled can be realized, and the situation that the cooling effect of the steel ball to be cooled is affected by the connection of the steel ball to be cooled with other high-temperature steel balls can be avoided.

[0043] The push device 200 is arranged at the entrance of the temperature control box 100, and the turnover device 300 is arranged at the exit of the temperature control box 100. The push device 200 can push the steel ball 140 to be cooled into the spiral roller 120 from the entrance of the temperature control box 100, and the steel ball 140 to be cooled rolls out of the temperature control box 100 after passing through the spiral roller, and then rolls into the turnover device 300. The turnover device 300 can turn the steel ball 140 to be cooled over the shaft quenching mechanism. The push device 200 pushes one steel ball 140 to be cooled to the baffle 110 at a time, and the turnover device 300 turns one steel ball into the quenching device at a time. Through the arrangement of the push device and the turnover device for controlling the passing of the steel ball to be cooled, the steel ball to be cooled can be isolated from other high-temperature steel balls. The independent cooling treatment of the steel ball to be cooled is realized, and the situation that the cooling effect of the steel ball to be cooled is affected by the connection of the steel ball to be cooled with other high-temperature steel balls is avoided.

[0044] In some embodiments, the spiral roller is provided with a plurality of steel ball channels, one end of the steel ball channel is communicated with the entrance of the temperature control box, and the other end of the steel ball channel is communicated with the exit of the temperature control box. Through the arrangement that the steel ball channel is communicated with the entrance and the exit of the temperature control box, the independent cooling of the steel ball to be cooled can be controlled, and the temperature balance of the temperature control box to the steel ball to be cooled is improved.

[0045] In some embodiments, the spiral roller is provided with a plurality of steel ball channels, one end of the steel ball channel is communicated with the entrance of the temperature control box, and the other end of the steel ball channel is communicated with the exit of the temperature control box. Through the arrangement that the steel ball channel is communicated with the entrance and the exit of the temperature control box, the independent cooling of the steel ball to be cooled can be controlled, and the temperature balance of the temperature control box to the steel ball to be cooled is improved.

[0046] In some embodiments, the push device includes a push cylinder for pushing the steel ball to be cooled to roll into the spiral roller, and the turnover device includes a turnover cylinder for pushing the steel ball to be cooled to turn from one side to the other side of the turnover device. Through the arrangement of the turnover cylinder and the push cylinder, the running speed of the steel ball to be cooled can be improved, and the working efficiency of the temperature control equipment of the steel ball is improved.

[0047] The temperature control device of the steel ball is provided with a plurality of push cylinders and a plurality of turnover cylinders.

The turnover cylinder is arranged on the side away from the turnover device gap, and the turnover cylinder pushes the turnover device to turn over. When the surface temperature of the steel ball to be cooled 140 is less than or equal to 750 DEG C, the control terminal controls the baffle 110 to open, and the push cylinder pushes the steel ball to be cooled 140 to accelerate into the spiral roller 120 of the temperature control box 100. After the steel ball to be cooled 140 passes through the spiral roller 120 of the temperature control box 100 and enters the turnover device 300, the turnover cylinder pushes the steel ball to be cooled to accelerate and turn over into the quenching device. Through the arrangement of the turnover cylinder and the push cylinder, the running speed of the steel ball to be cooled can be improved, and the working efficiency of the temperature control device of the steel ball can be improved.

[0048] In some embodiments, the turnover device is provided with a gap for accommodating the steel ball to be cooled. The gap of the turnover device can be circular, arc-shaped, square, or polygonal. The diameter of the turnover device gap is 1.5 times the diameter of the steel ball to be cooled, which can avoid the gap being too small to block the steel ball to be cooled, and can also avoid the gap being too large to pop out the steel ball to be cooled. By providing the turnover device with a gap, it is ensured that the steel ball to be cooled can be turned over in the turnover device, and it is also ensured that the steel ball to be cooled can normally enter the turnover device, thereby improving the stability of the turnover device in conveying the steel ball.

[0049] In some embodiments, the temperature control device of the steel ball is provided with a plurality of temperature control units and a temperature control box. Each temperature control unit includes a turnover device, a push device, a sensing device, and a fan, and each temperature control box includes a spiral roller and a plurality of inlets and a plurality of outlets.

[0050] In some embodiments, the temperature control device of the steel ball further includes a slide arranged on one side of the turnover device. In the case that the steel ball to be cooled enters the turnover device, the turnover cylinder is used to turn over the gap to face the slide. Through the arrangement of the slide, the contact time of the steel ball to be cooled with air can be prolonged, and the cooling process of the steel ball to be cooled can be further realized.

[0051] In some embodiments, the temperature control device of the steel ball further includes a slide arranged on one side of the turnover device.

[0052] In some embodiments, the side wall of the temperature control box 100 is provided with a heat preservation layer. The heat preservation material of the heat preservation layer can be glass wool or rock wool. By arranging the heat preservation material on the side wall of the temperature control box 100, the temperature of the outside environment can be prevented from being transmitted to the temperature control box 100, and at the same time, the second cooling process of the steel ball to be cooled is completed by reducing the rotation speed of the spiral roller 120 in the temperature control box 100. By arranging the heat preservation layer in the temperature control box 100 and controlling the low-speed operation of the spiral roller 120, the cooling process of the steel ball to be cooled can be ensured to proceed normally, the interference of the outside environment can be avoided, the rate of temperature drop can be accurately controlled, and the quality of the steel ball to be cooled can be improved.
