Description

Technical Field

[0001] The present invention relates to the technical field of induction heating furnaces, and particularly relates to a tunnel-type induction heating furnace for processing titanium alloy bars. Background Art

[0002] A tunnel-type induction heating furnace is a device for heating metal materials, and is usually applied to fields such as heat treatment processes, welding, and surface treatment of metals. Its working principle is through induction heating technology, where eddy currents are generated inside the metal by an electromagnetic field, thereby raising the temperature of the metal surface or a specified area. Due to the design of the tunnel furnace structure, the material can maintain a uniform heating effect within the heating area during the heating process, avoiding phenomena of local overheating or overcooling. This device is usually used in combination with an automatic feeding system, which can automatically pass the metal material through the furnace body to ensure efficient production. The tunnel-type induction heating furnaces in the prior art usually cannot achieve automatic intermittent loading and unloading, and the furnace body cannot be automatically opened and closed, resulting in poor heating quality.

A front eccentric column is eccentrically fixedly installed on the front eccentric rotating wheel, and a rear eccentric column is eccentrically fixedly installed on the rear eccentric rotating wheel;

[0005] The loading and unloading mechanism includes two lifting toothed plates and two fixed toothed plates. Four inclined surfaces are provided on the fixed toothed plate, and three inclined surfaces are provided on the lifting toothed plate. In the initial state, the three inclined surfaces of the lifting toothed plate and the rear three inclined surfaces of the fixed toothed plate are in the same plane. When the lifting toothed plate rises, the three inclined surfaces of the lifting toothed plate and the front three inclined surfaces of the fixed toothed plate are in the same plane.

[0006] Furthermore, the conveying mechanism further includes a number of floor feet fixedly installed at the bottom of the housing. Two conveying wheels are rotatably installed inside the housing. An upper transmission wheel is fixedly installed on the conveying wheel. A conveyor belt is wound around the two conveying wheels. A number of placing rollers are rotatably installed at equal intervals on the conveyor belt. A self-rotating gear is fixedly installed on every other placing roller. Two front sensor brackets and two rear sensor brackets are fixedly installed on the housing. A front sensor is fixedly installed on the front sensor bracket.

An inner transmission belt is wound around the rear transmission wheel and the inner transmission wheel. A front transmission belt is wound around the front outer wheel and the inner transmission wheel.

[0008] The inner motor drives the motor bevel gear to rotate, thereby driving the transmission shaft, the inner transmission wheel and the outer transmission wheel to rotate through the side bevel gear. The outer transmission wheel drives the upper transmission wheel and the conveying wheel to rotate through the vertical transmission belt, thereby driving the placing rollers to move. The placing rollers convey the titanium alloy bars located thereon. The inner transmission wheel drives the front outer wheel and the front eccentric runner to rotate through the front transmission belt. The inner transmission wheel drives the rear transmission wheel and the rear eccentric runner to rotate through the inner transmission belt.

[0009] Furthermore, the heating mechanism includes an induction coil disposed inside the furnace hood. A fixed rack is fixedly installed inside the housing. The fixed rack meshes with the self-rotating gear. The fixed rack and the self-rotating gear are made of ceramic material.

[0010] Furthermore, two door opening modules are provided on the heating furnace body. The door opening module includes a closing electric cylinder fixedly installed on the heating furnace body. A lifting plate is fixedly installed on the output end of the closing electric cylinder. A lifting column is fixedly installed on the lifting plate. The lifting column is slidably installed on the heating furnace body. A door panel is fixedly installed below the lifting column. The door panel is slidably installed on the heating furnace body.

The closing electric cylinder of the door opening module closer to the rear sensor prediction is electrically connected to the rear sensor.

[0011] When the titanium alloy bar passes between the two front sensors, the front sensors detect the titanium alloy bar, and control the closing cylinder near the front sensor side to extend, thereby driving the lifting plate, lifting column and door panel to rise. The titanium alloy bar enters the heating furnace body, and then enters the furnace hood. When the titanium alloy bar enters the heating furnace body, the closing cylinder contracts, causing the door panel to close, sealing the heating furnace body. The titanium alloy bar is subjected to enclosed induction heating through the induction coil. When the titanium alloy bar moves between the two rear sensors, the rear sensors detect the titanium alloy bar, and control the closing cylinder near the rear sensor side to extend, thereby driving the lifting plate, lifting column and door panel to rise, and the titanium alloy bar leaves the heating furnace body.

[0012] After the titanium alloy bar enters the heating furnace body, under the action of the fixed rack, the placing roller provided with the self-rotating gear rotates, and the rotation of the placing roller drives the titanium alloy bar to rotate, realizing the full heating of the titanium alloy bar.

[0014] Further, the loading and unloading mechanism on one side of the inner motor is used for loading the titanium alloy bar. The front eccentric column slides in the chute of the transverse groove rod. The loading and unloading mechanism on one side of the rear eccentric runner is used for unloading the titanium alloy bar. The rear eccentric column slides in the chute of the transverse groove rod.

[0015] During use, the titanium alloy bar is placed on the lifting tooth plate and the fixed tooth plate of the loading and unloading mechanism on one side of the inner motor. At this time, the three titanium alloy bars are respectively located on the rear three inclined planes of the fixed tooth plate, and at the same time, the 3 titanium alloy bars are respectively located on the front three inclined planes of the lifting tooth plate. The rotation of the front eccentric runner will drive the transverse groove rod, lifting slide rod, lifting top frame, connecting column and lifting tooth plate to rise and fall through the cooperation of the front eccentric column and the chute of the transverse groove rod. During the rising process of the lifting tooth plate, the 3 titanium alloy bars located in the fixed tooth plate will be respectively jacked up, so that the three titanium alloy bars move forward once respectively. The titanium alloy bar at the forefront is jacked out of the fixed tooth plate and falls onto the two placing rollers. Each time the lifting tooth plate rises and falls, the titanium alloy bar at the forefront on the fixed tooth plate is loaded onto the placing rollers, and the titanium alloy bar at the rear moves forward once.

[0016] Similarly, the rotation of the rear eccentric runner will drive the lifting tooth plate of the loading and unloading mechanism on one side of the rear eccentric runner to rise and fall through the cooperation of the rear eccentric column and the chute of the transverse groove rod, thereby realizing discharging.

[0017] The beneficial effects of the present invention compared with the prior art are as follows: (1) The conveying mechanism provided in the present invention can drive the titanium alloy bar to be automatically conveyed at a constant speed.

[0035] As Figure 2 , Figure 3 shown, an inner motor 105 is fixedly installed in the housing 101. A motor bevel gear 106 is fixedly installed on the motor shaft of the inner motor 105. A transmission shaft 109 is rotatably installed in the housing 101.

An inner transmission belt 112 is wound around the rear transmission wheel 117 and the inner transmission wheel 108. A front transmission belt 116 is wound around the front outer wheel 113 and the inner transmission wheel 108.

[0036] The inner motor 105 drives the motor bevel gear 106 to rotate, thereby driving the transmission shaft 109, the inner transmission wheel 108 and the outer transmission wheel 110 to rotate through the side bevel gear 107. The outer transmission wheel 110 drives the upper transmission wheel 121 and the conveying wheel 120 to rotate through the vertical transmission belt 111, thereby driving the placement roller 123 to move.

The fixed rack 208 meshes with the self-rotating gear 124. The fixed rack 208 and the self-rotating gear 124 are made of ceramic material.

[0038] As Figures 4 - 7 shown, two door opening modules are arranged on the heating furnace body 201. The door opening module includes a closing electric cylinder 202 fixedly installed on the heating furnace body 201. A lifting plate 203 is fixedly installed on the output end of the closing electric cylinder 202. A lifting column 204 is fixedly installed on the lifting plate 203. The lifting column 204 is slidably installed with the heating furnace body 201. A door panel 205 is fixedly installed below the lifting column 204.

[0039] When the titanium alloy bar 4 passes between the two front sensors 103, the front sensor 103 detects the titanium alloy bar 4 and controls the closing electric cylinder 202 on the side close to the front sensor 103 to extend, thereby driving the lifting plate 203, the lifting column 204 and the door panel 205 to rise. The titanium alloy bar 4 enters the heating furnace body 201, and then enters the furnace hood 206. After the titanium alloy bar 4 enters the heating furnace body 201, the closing electric cylinder 202 contracts, causing the door panel 205 to close, making the heating furnace body 201 sealed. The induction coil 207 performs sealed induction heating on the titanium alloy bar 4. When the titanium alloy bar 4 moves between the two rear sensors 104, the rear sensor 104 detects the titanium alloy bar 4 and controls the closing electric cylinder 202 on the side close to the rear sensor 104 to extend, thereby driving the lifting plate 203, the lifting column 204 and the door panel 205 to rise.

[0040] After the titanium alloy bar 4 enters the heating furnace body 201, under the action of the fixed rack 208, the placing roller 123 provided with the self-rotating gear 124 rotates, and the rotation of the placing roller 123 drives the titanium alloy bar 4 to rotate, realizing the full heating of the titanium alloy bar 4.

[0041] As Figures 8 - 11 shown, the loading and unloading mechanism further includes a lifting slide bar 302 slidably installed in the fixed frame 301.

A connecting folding plate 306 is fixedly installed on the adjusting connecting plate 305. The connecting folding plate 306 is fixedly installed with the fixed tooth plate 309.

[0042] As Figures 8 - 11 shown, the loading and unloading mechanism on one side of the inner motor 105 is used for loading the titanium alloy bar 4. The front eccentric column 115 slides in the chute of the transverse groove bar 303. The loading and unloading mechanism on one side of the rear eccentric runner 118 is used for unloading the titanium alloy bar 4. The rear eccentric column 119 slides in the chute of the transverse groove bar 303.

[0043] During use, the titanium alloy bar 4 is placed on the lifting tooth plate 308 and the fixed tooth plate 309 of the loading and unloading mechanism on one side of the inner motor 105. At this time, the three titanium alloy bars 4 are respectively located on the rear three inclined planes of the fixed tooth plate 309, and at the same time, the 3 titanium alloy bars 4 are respectively located on the front three inclined planes of the lifting tooth plate 308. The rotation of the front eccentric runner 114 will drive the transverse groove bar 303, the lifting slide bar 302, the lifting top frame 304, the connecting column 307 and the lifting tooth plate 308 to rise and fall through the cooperation of the front eccentric column 115 and the chute of the transverse groove bar 303. During the rising process of the lifting tooth plate 308, the 3 titanium alloy bars 4 located inside the fixed tooth plate 309 will be respectively jacked up, so that the three titanium alloy bars 4 move forward once respectively. The titanium alloy bar 4 at the forefront is jacked out of the fixed tooth plate 309 and falls onto the two placing rollers 123. Each time the lifting tooth plate 308 rises and falls, the titanium alloy bar 4 at the forefront on the fixed tooth plate 309 is loaded onto the placing rollers 123, and the titanium alloy bar 4 at the rear moves forward once.

[0044] Similarly, the rotation of the rear eccentric runner 118 will drive the lifting tooth plate 308 of the loading and unloading mechanism on one side of the rear eccentric runner 118 to rise and fall through the cooperation of the rear eccentric column 119 and the chute of the transverse groove bar 303, thereby realizing discharging.

[0045] The working principle of a tunnel - type induction heating furnace for processing titanium alloy bars disclosed in the present invention is as follows: When in use, the titanium alloy bars 4 are placed on the lifting tooth plate 308 and the fixed tooth plate 309 of the loading and unloading mechanism on one side of the inner motor 105. At this time, the three titanium alloy bars 4 are respectively located on the last three inclined surfaces of the fixed tooth plate 309, and at the same time, the 3 titanium alloy bars 4 are respectively located on the first three inclined surfaces of the lifting tooth plate 308. The rotation of the front eccentric runner 114 will drive the lifting of the cross - slot rod 303, the lifting slide rod 302, the lifting top frame 304, the connecting column 307 and the lifting tooth plate 308 through the cooperation of the front eccentric column 115 and the chute of the cross - slot rod 303. During the rising process of the lifting tooth plate 308, the 3 titanium alloy bars 4 located in the fixed tooth plate 309 will be respectively lifted, so that the three titanium alloy bars 4 move forward once respectively. The titanium alloy bar 4 at the forefront is pushed out of the fixed tooth plate 309 and falls onto the two placing rollers 123. Each time the lifting tooth plate 308 rises and falls, the titanium alloy bar 4 at the frontmost position on the fixed tooth plate 309 is loaded onto the placing rollers 123, and the titanium alloy bars 4 at the rear move forward once. The inner motor 105 drives the motor bevel gear 106 to rotate, thereby driving the transmission shaft 109, the inner transmission wheel 108 and the outer transmission wheel 110 to rotate through the side bevel gear 107. The outer transmission wheel 110 drives the upper transmission wheel 121 and the conveying wheel 120 to rotate through the vertical transmission belt 111, thereby driving the placing rollers 123 to move. The placing rollers 123 convey the titanium alloy bars 4 located thereon. The inner transmission wheel 108 drives the front outer wheel 113 and the front eccentric runner 114 to rotate through the front transmission belt 116, and the inner transmission wheel 108 drives the rear transmission wheel 117 and the rear eccentric runner 118 to rotate through the inner transmission belt 112. When the titanium alloy bar 4 passes between the two front sensors 103, the front sensors 103 detect the titanium alloy bar 4 and control the closing cylinder 202 on the side close to the front sensor 103 to extend, thereby driving the lifting plate 203, the lifting column 204 and the door plate 205 to rise. The titanium alloy bar 4 enters the heating furnace body 201, and then enters the furnace hood 206. After the titanium alloy bar 4 enters the heating furnace body 201, the closing cylinder 202 contracts, causing the door plate 205 to close, so that the heating furnace body 201 is sealed, and the titanium alloy bar 4 is subjected to enclosed induction heating through the induction coil 207. When the titanium alloy bar 4 moves between the two rear sensors 104, the rear sensors 104 detect the titanium alloy bar 4 and control the closing cylinder 202 on the side close to the rear sensor 104 to extend, thereby driving the lifting plate 203, the lifting column 204 and the door plate 205 to rise. The titanium alloy bar 4 leaves the heating furnace body 201. Similarly, the rotation of the rear eccentric runner 118 will drive the lifting of the lifting tooth plate 308 of the loading and unloading mechanism on one side of the rear eccentric runner 118 through the cooperation of the rear eccentric column 119 and the chute of the cross - slot rod 303, thereby realizing discharging.
