[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, the steel ball enters the L-shaped curved pipe through the spacer ring strip. The L-shaped curved pipe, the first slot frame and the feed conduit are the guiding passages for the steel ball. The steel ball enters the steel ball transportation passage composed of the four first section rods. The high-frequency coil heating devices provided by the three groups are used to heat the steel ball, thereby improving the transportation and heating effect of the steel ball. The heated steel ball enters the redirecting conduit through the passage composed of the four first section rods. The heated steel ball is guided by the redirecting conduit so that the steel ball is transported from the other end of the redirecting conduit to the inside of the four second section rods. The water pump is started to extract water from the inside of the pool through the diverting pipe and enters the inside of the circle pipe. Finally, the water is discharged through the drainage holes provided inside the circle pipe, thereby cooling down the tempered heated steel ball transported and moved inside the four second section rods. The fixed high-frequency coil heating device and the cooling structure are used to temper the moving steel ball inside the section rod track. When the steel ball moves, the steel ball performs multi-directional self-spinning movement inside the section rod track to ensure that the steel ball is fully heated, thereby improving the tempering cooling efficiency of the steel ball.

[0015] 2. In the present invention, the tempered steel ball after cooling enters the rear end of the discharge conduit and is discharged through the left end of the discharge conduit. Since the slide plate mechanism and the ball storage mechanism are reset to the initial state, the moving steel ball passes through the spacer ring bar and decelerates to enter the inner wall of the guide groove. The leftmost steel ball abuts against the pressure touch plate and limits the position, and the steel ball on the right side abuts against the steel ball entering the guide groove on the left side in turn until multiple steel balls are flatly placed inside the guide groove. After the tempered steel ball is loaded, the first stepper motor is started in forward rotation until the top of the plate body abuts against the bottom end of the first limit block set at the top and limits the position, the second stepper motor is started in forward rotation, and the main shaft of the second stepper motor is driven by the forward rotation of the second threaded rod to rotate, driving the pressure touch plate to move rightward, squeezing the steel ball placed inside the guide groove, and the steel ball passes through the spacer ring bar into the L-shaped bent pipe. The L-shaped bent pipe, the first slot frame and the feeding conduit are the guide passages for the steel balls. The steel balls enter the steel ball transportation passage composed of the four first section rods to form a cyclic tempering treatment structure, which can meet the multiple tempering treatment requirements for the steel balls.

[0016] 3. In the present invention, when the slide plate mechanism is located at the bottom position in the loading process, at this time, the bottom end of the plate body abuts against the first limit block set at the bottom, and the rear end support plate of the pressure touch plate abuts against the second limit block set on the left side. Personnel can select different numbers of steel balls to be tempered and lay them flat in the guide groove. Within the maximum number of steel balls placed in the guide groove, the number of steel balls placed can be customized and placed manually to meet the free selection of the number of steel balls put into the same batch for different tempering treatments. The spacer ring strips fixed on the inner wall of the guide groove play a protective role in preventing the steel balls from slipping in the horizontal direction of the guide groove.

[0060] Working process: The high-frequency coil heating device 110, the first stepper motor 33, the second stepper motor 387, the third stepper motor 47, the water pump and the water supply pump of the present invention are all electrically connected to the external power supply, and the above-mentioned electrical devices are all started and controlled by the PLC controller.

[0061] like Figure 1 , Figure 2 As shown, the device body is in the initial state, and the slide plate mechanism 37 is at the bottom position. At this time, the bottom end of the plate body 371 abuts against the first limit block 36 set at the bottom, and the rear end support plate of the pressure touch plate 389 abuts against the second limit block 384 set on the left side. Personnel lay a plurality of steel balls to be tempered flatly inside the guide groove 372, wherein the spacer ring strip 373 fixedly arranged on the inner wall of the guide groove 372 plays a protective role in preventing the steel balls from slipping in the horizontal direction of the guide groove 372.

[0062] S1. After the tempered steel balls are loaded, the first stepper motor 33 is started in forward rotation. The main shaft of the first stepper motor 33 drives the first threaded rod 34 to rotate. The first threaded rod 34 and the internal thread of the plate 371 rotate. Under the vertical limiting action of the plate 371 and the first round rod 35, the slide plate mechanism 37 and the ball storage mechanism 38 are driven to rise until the top of the plate 371 contacts the bottom of the first limiting block 36 set on the top. At this time, the right end of the plate 371 is in contact with the L-shaped elbow 45.

[0063] S2, the second stepper motor 387 is started in the forward direction, and the main shaft of the second stepper motor 387 rotates in the forward direction to drive the second threaded rod 388 to rotate. The second threaded rod 388 and the internal thread of the front support plate of the pressure touch plate 389 rotate, and under the sliding limit of the rear support plate of the pressure touch plate 389 and the second round rod 383, the pressure touch plate 389 is driven to move right, squeezing the steel balls placed in the guide groove 372 until the rear support plate of the pressure touch plate 389 contacts the second limit block 384 set on the right side, so that all the steel balls in the guide groove 372 move to the right and are discharged, and then the second stepper motor 387 is started in the reverse direction, and the first stepper motor 33 is started in the reverse direction, so that the slide plate mechanism 37 and the ball storage mechanism 38 are reset as shown. Figure 1 , Figure 2 The initial state shown;

[0064] S3, at this time, the steel ball passes through the spacer ring 373 and enters the L-shaped elbow 45. The L-shaped elbow 45, the first slot frame 107 and the feed conduit 106 are guide passages for the steel ball. The steel ball enters the steel ball transport passage composed of the four first section rods 109. The steel ball moves along the steel ball transport passage composed of the four first section rods 109. The high-frequency coil heating devices 110 arranged in three groups heat the steel ball with high-frequency coils, thereby improving the transportation and heating effect of the steel ball.

[0065] S4. The heated steel balls enter the redirecting conduit 111 through the passage formed by the four first-section rods 109, and the heated steel balls are guided by the redirecting conduit 111 so that the steel balls are transported from the other end of the redirecting conduit 111 to the four second-section rods 112. The water pump is started to draw water from the pool 116 into the circle tube 114 through the diverting pipe 115, and finally discharged through the drainage holes provided in the circle tube 114, so as to cool down the tempered heated steel balls transported and moved in the four second-section rods 112. The tempered steel balls after cooling enter the rear end of the discharge conduit 113 and are discharged through the left end of the discharge conduit 113. Since the slide mechanism 37 and the ball storage mechanism 38 are reset as shown in FIG. Figure 1 , Figure 2 In the initial state shown, the moving steel ball passes through the spacer ring 373 and decelerates to enter the inner wall of the guide groove 372, the leftmost steel ball abuts against the pressure touch plate 389 to limit the position, and the right steel ball abuts against the steel ball entering the guide groove 372 on the left side to limit the position in turn, until multiple steel balls are flatly placed inside the guide groove 372;

[0066] The steel ball is subjected to multiple tempering cooling, and steps S1-S4 may be repeated;

[0067] When the steel balls are discharged, step S1 is repeated after the above step S4, and then the third stepper motor 47 is started in forward rotation, and the main shaft of the third stepper motor 47 drives the second gear 48 to rotate. Since the second gear 48 is in meshing contact with the first gear 46, the first gear 46 and the L-shaped elbow 45 can be driven to rotate until the L-shaped elbow 45 is in contact with the second lining plate 53, wherein the L-shaped elbow 45, the second lining plate 53 and the second groove frame 52 form a guide discharge structure for the steel balls, and then step S2 is repeated;

[0068] At this time, the steel balls pass through the spacer ring 373 and enter the L-shaped bent pipe 45. The L-shaped bent pipe 45, the second lining plate 53 and the second slot frame 52 are the guiding discharge passages for the steel balls. The steel balls pass through the second slot frame 52 and enter the spiral discharge pipe 54, and are discharged through the guide area of ​​the inclined platform 55, the ball frame 56 and the discharge plate 57. A chain conveyor belt for transmitting steel balls can be provided at the bottom left side of the inclined platform 55. The steel balls that fall on the chain conveyor belt are continuously transported and moved, so as to be conveniently transported to the next steel ball processing area.
