[0002] Metal heat treatment refers to a processing technology that changes the material properties in a targeted manner by heating, keeping warm and cooling solid metal materials. Compared with other processes, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but changes its properties by changing the internal microstructure. However, due to the special nature of heat treatment that requires heat preservation, the treatment process is very long, which is not conducive to mass production and increases the workload of employees. The alloy heat treatment device in the prior art usually requires manual labor to continuously put in and take out the alloy parts, and cannot achieve continuous automatic heat treatment operations of the alloy parts. At the same time, after the heat treatment of the alloy parts is completed, it is impossible to automatically feed and discharge the materials, and the degree of automation is low.

At the same time, the lower pushing plate pushes the alloy plate on the lower layer of the feed box to the hanging plate that has just moved to the stop plate. The transmission belt is used to assist the movement of the alloy plate.

[0007] The movement of the pull rope rod will cause the pull rope to bypass the inner roller and the outer roller to pull the lifting frame and the support block upward along the fixed frame, and the lifted lifting rod block and the lifting rod will be pushed onto the push-out slide rail through the support block, and finally the lifting rod block will leave the device along the push-out slide rail.

At this time, the push cylinder extends to drive the pull rope rod to slide along the fixed frame, and the lifting rod block is pushed into the lifting rod through the pull rope rod. The lifting rod enters the slide block, and the chain rope passes through the rope feeding groove, and then the lifting rod and the lifting rod block are driven to leave the slide block through the movement of the rotating disk. At this time, the release spring rebounds to the initial position, waiting for the next lifting mechanism to enter.

[0014] The rotation of the upper gear will drive the rotating gear and the rotating disk to rotate, and the alloy plate on the hanging plate entering therein is heat treated through the heating furnace.

[0015] The intermittent motor rotates intermittently. When the conveyor belt drives the lifting rod and the lifting rod block to move to the side of the descending frame, the intermittent motor stops rotating, and at this time the pushing electric cylinder retracts and contracts once to feed and unload the alloy plate. When the lifting rod falls into the chute block, the intermittent motor starts to rotate.

[0026] like Figure 4-Figure 6As shown, a lifting mechanism is provided on the bracket block 214, and the lifting mechanism includes a lifting rod block 216 slidably installed in the bracket block 214, a lifting rod 215 is fixedly installed on the lifting rod block 216, four chain ropes 217 are provided on the lifting rod 215, and a hanging plate 218 is provided at the lower end of the chain rope 217.

[0028] When the alloy plate is pushed onto the hanging plate 218, the intermittent motor 203 rotates to drive the motor gear 204 to rotate, and drives the lower gear 205 and the upper gear 207 to rotate through the lower transmission belt 206, thereby driving the upper gear shaft 208 and the upper bevel gear 209 to rotate, driving the side bevel gear 210, the side gear shaft 211 and the driving wheel 212 to rotate, and the driving wheel 212 rotates to drive the conveyor belt 213 to move, thereby driving the lifting rod block 216 and the lifting rod 215 to move through the bracket block 214, thereby driving the alloy plate to move to the side of the descending frame 221 through the chain rope 217 and the hanging plate 218. At this time, the push cylinder 103 extends to drive the rope rod 107 to slide along the fixed frame 102, and the lifting rod block 216 is brought by the rope rod 107 to move the lifting rod 2 15 is pushed into the sliding block 223. At this time, due to the weight of the lifting mechanism and the alloy plate, the descending frame 221 descends along the side slide rail 222, and the release spring 219 is slowly stretched. When the hanging plate 218 and the alloy plate contact the outer furnace door 304 and the inner furnace door 306, the outer furnace door 304 and the inner furnace door 306 are pushed outward through the slope of the outer furnace door 304 and the inner furnace door 306, the outer furnace spring 305 and the inner furnace spring 307 are compressed, and the lifting rod 215 enters the slide block 309, and the chain rope 217 passes through the rope feeding groove 310, and then the lifting rod 215 and the lifting rod block 216 are driven to leave the sliding block 223 through the movement of the rotating disk 302. At this time, the release spring 219 rebounds to the initial position, waiting for the next lifting mechanism to enter.

[0029] like Figure 7-Figure 9 As shown, the heating device includes a rotating disk 302 rotatably mounted on a heating furnace 301, and the heating furnace 301 is used to perform heat treatment heating on the alloy parts. A rotating gear 303 is fixedly mounted on the rotating disk 302, and the rotating gear 303 is meshed with the upper gear 207. A center block 308 is fixedly mounted on the rotating disk 302, and four furnace door mechanisms are arranged on the rotating disk 302.

[0030] like Figure 7-Figure 9As shown, the furnace door mechanism includes an outer furnace door 304 and an inner furnace door 306 which are slidably mounted on a rotating disk 302, and slopes are arranged on the outer furnace door 304 and the inner furnace door 306. An outer furnace spring 305 is arranged between the outer furnace door 304 and the rotating disk 302, and an inner furnace spring 307 is arranged between the inner furnace door 306 and the center block 308. Four groups of slide blocks 309 are arranged on the rotating disk 302, and rope feeding grooves 310 are arranged on the outer furnace door 304 and the inner furnace door 306.

[0031] The rotation of the upper gear 207 will drive the rotating gear 303 and the rotating disk 302 to rotate, and the alloy plate on the hanging plate 218 entering therein is heat treated through the heating furnace 301. Then, when the rotating disk 302 drives the lifting rod 215 and the lifting rod block 216 to move to the support block 112 through the outer furnace door 304 and the inner furnace door 306, the lifting rod block 216 enters the support block 112, and then the lifting rod block 216, the lifting rod 215, the chain rope 217, the hanging plate 218 and the alloy block that has completed the heat treatment are pulled up through the support block 112.

[0032] The intermittent motor 203 rotates intermittently. When the conveyor belt 213 drives the lifting rod 215 and the lifting rod block 216 to move to the side of the descending frame 221, the intermittent motor 203 stops rotating, and at this time the pushing electric cylinder 103 retracts and contracts once to feed and discharge the alloy plate. When the lifting rod 215 falls into the chute block 309, the intermittent motor 203 starts to rotate. Each rotation of the intermittent motor 203 will drive the rotating disk 302 to rotate a quarter of a turn through the upper gear 207.

[0033] The working principle of the continuous heat treatment device for alloy parts disclosed in the present invention is: the alloy plate is placed in the upper layer of the feed box 101, the pushing electric cylinder 103 is extended to drive the lower pushing plate 109 and the upper pushing plate 108 to slide along the feed box 101, and at the same time drive the pull rope rod 107 to slide along the fixed frame 102, the upper pushing plate 108 pushes the alloy plate placed on the upper layer of the feed box 101 to the lower layer of the feed box 101, and at the same time the lower pushing plate 109 pushes the alloy plate on the lower layer of the feed box 101 to the hanging plate 218 that just moves to the stop plate 114, and the transmission belt 115 is used to assist the movement of the alloy plate. When the alloy plate is pushed onto the hanging plate 218, the intermittent motor 203 rotates to drive the motor gear 204 to rotate, and drives the lower gear 205 and the upper gear 207 to rotate through the lower transmission belt 206, thereby driving the upper gear shaft 208 and the upper bevel gear 209 to rotate, driving the side bevel gear 210, the side gear shaft 211 and the driving wheel 212 to rotate, and the driving wheel 212 rotates to drive the conveyor belt 213 to move, thereby driving the lifting rod block 216 and the lifting rod 215 to move through the bracket block 214, thereby driving the alloy plate to move to the side of the descending frame 221 through the chain rope 217 and the hanging plate 218. At this time, the push cylinder 103 extends to drive the rope rod 107 to slide along the fixed frame 102, and the lifting rod block 216 is brought by the rope rod 107 to move the lifting rod 2 15 is pushed into the sliding block 223. At this time, due to the weight of the lifting mechanism and the alloy plate, the descending frame 221 descends along the side slide rail 222, and the release spring 219 is slowly stretched. When the hanging plate 218 and the alloy plate contact the outer furnace door 304 and the inner furnace door 306, the outer furnace door 304 and the inner furnace door 306 are pushed outward through the slope of the outer furnace door 304 and the inner furnace door 306, the outer furnace spring 305 and the inner furnace spring 307 are compressed, and the lifting rod 215 enters the slide block 309, and the chain rope 217 passes through the rope feeding groove 310, and then the lifting rod 215 and the lifting rod block 216 are driven to leave the sliding block 223 through the movement of the rotating disk 302. At this time, the release spring 219 rebounds to the initial position, waiting for the next lifting mechanism to enter. The rotation of the upper gear 207 will drive the rotating gear 303 and the rotating disk 302 to rotate, and the alloy plate on the hanging plate 218 entering therein is heat treated through the heating furnace 301. Subsequently, when the rotating disk 302 drives the lifting rod 215 and the lifting rod block 216 to move to the support block 112 through the outer furnace door 304 and the inner furnace door 306, the lifting rod block 216 enters the support block 112, and the movement of the pull rope rod 107 will also bypass the inner roller 105 and the outer roller 106 through the pull rope 110 to pull the lifting frame 111 and the support block 112 upward along the fixed frame 102, that is, the lifting rod block 216, the lifting rod 215, the chain rope 217, the hanging plate 218 and the heat-treated alloy block are pulled up through the support block 112, and the lifted lifting rod block 216 and the lifting rod 215 are pushed onto the ejection slide rail 113 through the support block 112, and finally the lifting rod block 216 leaves the device along the ejection slide rail 113.The intermittent motor 203 rotates intermittently. When the conveyor belt 213 drives the lifting rod 215 and the lifting rod block 216 to move to the side of the descending frame 221, the intermittent motor 203 stops rotating, and at this time the pushing electric cylinder 103 retracts and contracts once to feed and discharge the alloy plate. When the lifting rod 215 falls into the chute block 309, the intermittent motor 203 starts to rotate. Each rotation of the intermittent motor 203 will drive the rotating disk 302 to rotate a quarter of a turn through the upper gear 207.
