[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 10 As shown in the figure, a tempering device for steel ball production and processing according to an embodiment of the present invention includes: a furnace body 1, a positioning plate 11 disposed inside the furnace body 1, a cooling chamber 111 formed inside the positioning plate 11, a plurality of receiving cylinders 113 rotatably connected to the side of the positioning plate 11 facing the center of the furnace body 1, the receiving cylinders 113 communicating with the cooling chamber 111 and rotatably connected to the positioning plate 11, a gear 114 sleeved at the connecting end of the receiving cylinder 113 and the positioning plate 11, a first steel chain 115 meshing with the outer side of the gear 114, a plurality of gears 114 inside the first steel chain 115 being horizontally distributed, and a plurality of vertically distributed gears 114 being sleeved with a The second steel chain 116, the first steel chain 115 and the second steel chain 116 are interleaved and mesh with the gear 114. The positioning plate 11 is rotatably connected to the side away from the receiving cylinder 113 with a rotating shaft 21. One end of the rotating shaft 21 is connected to the cooling chamber 111 and the other end extends to the outside of the furnace body 1. The end located in the cooling chamber 111 is fixedly connected to the end of the receiving cylinder 113 with a connecting shaft 211. The end of the rotating shaft 21 located outside the furnace body 1 is provided with a turntable 22. The transmission component 23 is installed on the side of the turntable 22. The side of the transmission component 23 away from the turntable 22 is provided with a drive component 24. The drive component 24 can drive the turntable 22 to rotate through the transmission component 23. When the steel ball is tempered by the tempering furnace, the cooling is realized by air cooling. For the steel ball which needs to improve the cooling speed, the cooling efficiency of the existing tempering furnace is low, and it is difficult to adapt to the tempering process of the steel ball which needs fast cooling speed. In order to solve the above problems, the embodiment of the present application is provided with the receiving cylinder 113 and other structures, and the specific use process is as follows: when the steel ball is tempered by the furnace body 1, the furnace cover of the furnace body 1 is opened, and then the steel ball is placed between the plurality of receiving cylinders 113, that is, a pair of receiving cylinders 113 cooperate to receive the steel ball. After the steel ball is placed, the furnace cover is closed, and the closed furnace cover will block the steel ball from falling off the end of the receiving cylinder 113. Then heating is carried out, and then cooling is carried out. When cooling, air is filled into the inside of the furnace body 1, and the air carries heat and is discharged from the furnace body 1. In this process, the driving assembly 24 drives the rotating shaft 21 to rotate through the transmission assembly 23 and the rotating disc 22. The rotating shaft 21 drives the receiving cylinder 113 to rotate through the connecting shaft 211. The receiving cylinder 113 drives the gear 114 sleeved at the end to rotate. The gear 114 drives all the receiving cylinders 113 to rotate through the meshing transmission with the first steel chain 115 and the second steel chain 116. The steel ball placed at the top end of the receiving cylinder 113 is driven to rotate synchronously. When the steel ball rotates, the contact position of the steel ball with the receiving cylinder 113 changes, so that the steel ball is fully contacted with the air, thereby improving the cooling speed of the steel ball, and being beneficial to adapt to the tempering of the steel ball which needs fast cooling speed.

[0022] The driving assembly 24 comprises: The driving motor is installed on the side surface of the mounting frame installed on the ground. The output end of the driving motor is connected with the transmission assembly 23. The transmission assembly 23 has heat insulation effect. When in use, the driving motor drives the transmission assembly 23 to rotate, and the transmission assembly 23 drives the rotating shaft 21 to rotate through the rotating disc 22. The high temperature in the furnace body 1 can be transmitted to the inside of the rotating disc 22 through the rotating shaft 21, and then transmitted to the inside of the transmission assembly 23. The transmission assembly 23 has heat insulation effect, so that a large amount of heat can be avoided to be transmitted to the driving motor through the transmission assembly 23, so that the driving motor is not damaged by high temperature.

[0023] The transmission assembly 23 comprises: The baffle 231 is installed at the end of the rotating shaft 21 outside the furnace body 1, and the axis of the rotating shaft 21 passes through the center of the baffle 231. A pair of air jets 232 are symmetrically arranged on both sides of the baffle 231, the nozzles of the air jets 232 are directed to the surface of the baffle 231, the air jets 232 are connected with air pipes, the air pipes are connected with air pumps, a connecting frame 233 is arranged between the air jets 232 and the output end of the driving motor, a temperature sensor 2331 is arranged on the side of the connecting frame 233, the temperature sensor 2331 is used to monitor the temperature of the driving motor, when the conduction assembly 23 works, the driving motor drives the air jets 232 to rotate through the connecting frame 233, the air jets 232 drive the baffle 231 to move synchronously, because the baffle 231 is installed at the non-central position of the rotating disc 22, the baffle 231 drives the rotating disc 22 to rotate, at this time, the air jets 232 at both ends of the baffle 231 are started by the air pump connected by the hose, the air jets 232 at both ends of the baffle 231 spray air flow to the baffle 231, and the air flow intensity on one side is controlled to be greater than that on the other side, so that the baffle 231 stops when the baffle 231 on both sides is no longer in contact with the air jets 232, the output power of the air pump connected with different air jets 232 is determined, and then when the rotating disc 22 restores to the initial angle, the air jets 232 on both sides of the baffle 231 maintain the determined air jet intensity, so that the baffle 231 does not continuously contact the air jets 232, which greatly prevents the baffle 231 from transferring the heat generated when the furnace body 1 is tempered, and effectively protects the driving motor. It should be pointed out that when the rotating disc 22 is initially rotated, the air jets 232 are in contact with the baffle 231 for a short time, and a large amount of heat transfer will not be generated in a short time, so the above effect will not be affected. Specifically, the temperature sensor 2331 is arranged on the side of the connecting frame 233, and the connecting frame 233 is in contact with the output end of the driving motor. Therefore, the temperature sensor 2331 can be used to monitor the temperature of the driving motor, and the temperature sensor 2331 is connected with the early warning device in the external environment through an electrical signal. Therefore, when the temperature of the driving motor reaches a certain size, the early warning device automatically starts to remind the staff to handle.

The air flow sprayed by the air jets 232 is guided to the designated area through the pair of guide plates 234, which prevents the air flow from being reflected and acting on the baffle 231 again, and is conducive to improving the stability of the baffle 231 driven by the air flow.

[0025] The side of the rotating disc 22 is provided with a butt joint hole 221 communicated with the through hole, and the side of the rotating disc 22 is provided with a water inlet assembly 222 communicated with the butt joint hole 221, and the water inlet assembly 222 is externally connected with a water pump; the water outlet pipe 112 is connected with the positioning plate 11 at one end and communicated with the cooling cavity 111; the other end penetrates to the outside of the furnace body 1; when the steel balls inside the furnace body 1 are cooled after tempering is completed, the water pump externally connected with the water inlet assembly 222 is started, the water pump injects liquid water into the butt joint hole 221 through the water inlet assembly 222, and then the liquid water is injected into the cooling cavity 111 through the through hole on the rotating shaft 21, the cooling cavity 111 is communicated with the receiving cylinder 113, and the water outlet pipe 112 penetrates to the outside of the furnace body 1, so that the liquid water in the cooling cavity 111 is discharged through the water outlet pipe 112, flows through the receiving cylinder 113, takes out the heat inside the receiving cylinder 113, and then takes out the heat inside the steel balls received by the receiving cylinder 113, and further accelerates the cooling of the steel balls.

[0026] The water inlet assembly 222 further comprises: The water inlet pipe 2221 is inserted into the butt joint hole 221 at one end and communicated with the output end of the water pump externally connected with the water inlet assembly 222 at the other end; the water inlet pipe 2221 is not in contact with the inner wall of the butt joint hole 221 when being inserted into the butt joint hole 221; the side of the water inlet pipe 2221 is provided with a support column 2222, and the bottom end of the support column 2222 is fixed to the ground; the water inlet pipe 2221 is supported by the support column 2222 and avoids contact with the butt joint hole 221, so that the rotating disc 22 cannot contact the water inlet pipe 2221 to transfer heat, and the water inlet pipe 2221 is effectively protected.

[0027] The tempering device further comprises: The side of the collecting cover 223 is provided with a gap, the collecting cover 223 is installed on the side of the rotating disc 22, the water inlet pipe 2221 penetrates the gap and is not in contact with the gap, the bottom end of the collecting cover 223 is communicated with a lead pipe 224, and the liquid water overflowing from the butt joint hole 221 can be guided through the collecting cover 223 and the lead pipe 224; when the liquid water is injected into the butt joint hole 221, the liquid water overflows from the gap between the water inlet pipe 2221 and the butt joint hole 221 under the action of hydraulic pressure, the overflowing liquid water can be guided through the collecting cover 223 and the lead pipe 224, and the concentrated collection of the liquid water is ensured.
