DETAILED DESCRIPTION

[0028] like Figure 1 and Figure 2 As shown, a medium frequency induction heating quenching control system includes a turntable 1, which is divided into an upper and lower layer, with a connecting channel between the two layers. The turntable 1 is used to accommodate the cutting machine blade to be quenched. The turntable 1 is started to rotate by a turntable motor 2. A transfer channel 3 is fixedly connected to the upper outlet of the turntable 1. The transfer channel 3 can only accommodate one blade to pass horizontally in a straight line. Notches are opened on both sides of the front end of the transfer channel 3. A roller conveyor belt 4 is arranged at the notch. The roller conveyor belt 4 is composed of a plurality of rollers, which are evenly distributed in a horizontal straight line. The middle surface is connected by a rubber belt. The roller conveyor belt 4 is driven to rotate by a roller motor. A blade notch is also opened on the lower surface of the transfer channel 3. The tail of the blade in the notch faces the transportation direction of the blade in the transfer channel 3. A falling channel 5 is arranged below the notch and the end of the transfer channel 3. A material dropping assembly 6 is arranged below the falling channel 5. The falling channel 5 can only accommodate one blade to fall.

[0029] The operator pours the blades into the turntable 1, which starts to rotate. The blades in the lower layer of the turntable 1 enter the upper layer through the connecting channel between the upper and lower layers. The blades in the upper layer of the turntable 1 enter the transfer channel 3 in a straight line through the upper layer outlet. When the turntable 1 starts to rotate, the roller conveyor belt 4 is also started. The blades in the transfer channel 3 are transported under the drive of the roller conveyor belt 4. Since the blades are rectangular, the blades entering the transfer channel 3 may have blades connected to each other or tails connected. That is, the blades are not transported in the same form in the transfer channel 3, and the tails of the blades may be connected. The blade transported forward passes through the falling channel 5 below the gap of the transfer channel 3 and falls into the corresponding blanking assembly 6 below. The blade transported forward with the blade facing forward passes through the falling channel 5 below the end of the transfer channel 3 and falls into the corresponding blanking assembly 6 below. An upper proximity switch 25 is provided at the upper part of the falling channel 5, and a lower proximity switch 26 is provided at the lower part. When the upper proximity switch 25 detects that the blades are stacked to the upper position of the falling channel 5, the turntable 1 and the roller conveyor belt 4 stop. When the lower proximity switch 26 detects that the blades have fallen to the lower position of the falling channel 5, the turntable 1 and the roller conveyor belt 4 restart.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, the blanking assembly 6 includes an upper clamping plate 17 and a lower clamping plate 18. The upper clamping plate 17 and the lower clamping plate 18 are in a relative group. Due to the same structure and function, only one group is taken as an example below. Spiral grooves are opened in the upper clamping plate 17 and the lower clamping plate 18, and the spiral grooves of the two have opposite rotation directions. A clamping plate rotating shaft 19 passes through the spiral grooves of the two. A protrusion is distributed in the middle of the lower surface of the upper clamping plate 17, and a groove 24 is distributed in the middle of the upper surface of the lower clamping plate 18. The protrusion of the upper clamping plate 17 is just located in the groove 24, and the thickness of the protrusion of the upper clamping plate 17 is greater than the depth of the groove 24, so that there is a gap of the thickness of a blade between the upper clamping plate 17 and the lower clamping plate 18. Usually, the distance between the lower clamping plates 18 is smaller than the distance between the upper clamping plates 17.

[0031] The upper end of the clamp plate rotating shaft 19 is fixedly connected to a connecting arm 20, and a clamp plate cylinder 21 is fixedly connected in the middle of the connecting arm 20. The blade falling from the falling channel 5 falls to the upper surface of the lower clamp plate 18, and then the clamp plate cylinder 21 extends out, and the clamp plate rotating shaft 19 moves in the spiral grooves in the upper clamp plate 17 and the lower clamp plate 18. Since the spiral grooves between the two rotate in opposite directions, the lower clamp plate 18 separates to both sides, the upper clamp plate 17 gathers inward, and the blade between the two gaps falls, and the blade above the gap is clamped by the upper clamp plate 17, and then the clamp plate cylinder 21 retracts, the lower clamp plate 18 gathers inward, the upper clamp plate 17 separates, and the clamped blade falls to the upper surface of the lower clamp plate 18 again. Since the blades and tails of the blades falling from the two falling channels 5 are opposite, the blades and tails of the blades falling from the surface of the lower clamp plate 18 are opposite, and the blades are distributed outward. A chain conveyor belt 7 is also provided below the blanking assembly 6, and the chain conveyor belt 7 and the transfer channel 3 are distributed perpendicular to each other.

[0032] like Figure 5 and Figure 6As shown, the chain conveyor belt 7 is composed of two mutually parallel elliptical chains, and a conveying assembly 8 is evenly fixed on the chain conveyor belt 7. The conveying assembly 8 includes a receiving plate 11, and a receiving groove is opened in the middle of the receiving plate 11. Support columns 14 are fixedly connected to both sides of the receiving groove. The end surface of the support column 14 is fixedly connected to a steering column 15. A through hole is also opened in the middle of the receiving plate 11, and a telescopic column 12 passes through the through hole. A cross bar 27 is fixedly connected to the upper end of the telescopic column 12. The cross bar 27 is located in the groove, and the lower surface of the cross bar 27 and the bottom of the receiving groove are connected. A tension spring 16 is connected between the ends, and a crimping rotating shaft 13 is provided at both ends of the cross bar 27. A crimping arm 28 is provided on the surface of the crimping rotating shaft 13. The crimping arm 28 is in a corner shape, and a crimping groove is opened in the crimping arm 28. The steering column 15 is embedded in the crimping groove. The crimping groove is in a corner shape. Normally, under the tension of the tension spring 16, the crimping arm 28 is horizontally and tightly attached to the upper surface of the receiving plate 11. The upper surface of the receiving plate 11 is also provided with a first photoelectric switch 30, and the telescopic column 12 extends out of the lower surface of the receiving plate 11.

[0033] The arc plates 22 and wedge blocks 23 are relatively distributed in the arc parts on both sides of the chain conveyor belt 7. The surface of the wedge block 23 is wedge-shaped and connected to the surface of the arc plate 22. When the telescopic column 12 passes through the wedge-shaped surface of the wedge block 23, it extends upward, driving the crimping arm 28 to move upward along the crimping groove. Since the crimping groove is a corner shape, the crimping arm 28 is centered on the crimping rotation axis 13, and the upper end gathers inward, so that the crimping arm 28 is separated from the upper surface of the receiving plate 11, and then is received by the arc plate 22, so that the conveying component 8 passing through the arc part of the chain conveyor belt 7 The middle crimping arm 28 is detached from the upper surface of the receiving plate 11, and the blanking assembly 6 is just located on both sides above the head end of the chain conveyor belt 7. The blade dropped from the blanking assembly 6 just falls onto the upper surface of the receiving plate 11. When the first photoelectric switch 30 detects that a blade has fallen from the upper surface of the receiving plate 11, the chain conveyor belt 7 advances the distance between one conveying assembly 8, the telescopic column 12 in the previous conveying assembly 8 is detached from the arc plate 22, the telescopic column 12 falls, and the crimping arm 28 presses the blade on the surface of the receiving plate 11, and the next conveying assembly 8 continues to receive a new blade.

[0034] Induction coils 10 are also provided on both sides of the end of the chain conveyor belt 7. The induction coils 10 are in an inverted U-shaped structure, and a medium-frequency induction current is connected inside, so that the blade filled therein can be inductively heated. A far-infrared sensor 29 and a second photoelectric switch 31 are also provided above the induction coils 10. When the second photoelectric switch 31 detects that a blade has entered the induction coil 10, the medium-frequency induction current is passed into the induction coil 10. The far-infrared sensor 29 is used to detect the heating temperature of the blade to control the magnitude of the medium-frequency induction current passed into the induction coil 10, so that the blade is maintained at a set temperature for uniform heating. When the telescopic column 12 in the conveying assembly 8 at the end of the chain conveyor belt 7 passes through the wedge-shaped surface of the wedge block 23 and extends upward again, the crimping arm 28 approaches and gathers upward, and the blade on the surface of the loosened receiving plate 11 flips over and falls when passing through the arc-shaped part of the chain conveyor belt 7. A water pool 9 is also provided below the end of the chain conveyor belt 7 to cool down the blade after high-temperature quenching.

[0035] like Figure 7 As shown, a medium frequency induction heating and quenching control system also includes a central controller, which is connected to an input part and an output part. The central controller is used to receive data detected by the input part and send operating instructions to the output part to realize the automatic operation of various parts in the medium frequency induction heating and quenching control system. The central controller is also connected to a display screen, which is used to display the operating status and parameters of various parts in the medium frequency induction heating and quenching control system.

[0036] The input part includes an upper proximity switch, a lower proximity switch, a far infrared sensor, a first photoelectric switch and a second photoelectric switch. The input part is used to monitor the operating data in the medium frequency induction heating and quenching control system. The output part includes a turntable motor, a roller conveyor belt, a chain conveyor belt, an induction coil and a clamping plate cylinder. The central controller sends an operating instruction to the output part through the operating data detected by the input part to realize the automatic operation of the medium frequency induction heating and quenching control system.
