[0015] In the initial state, the convex ball is located at the highest point of the arc rail, and the lifting cylinder is in the shortest state. When the cam rotates and presses the switch, the lifting cylinder retracts and contracts twice. The lifting cylinder first extends, and drives the sliding sleeve to descend along the fixed track column through the connecting frame. The convex ball moves along the arc rail to the vertical rail. When the arc rail just enters the vertical rail, the fixed claw and the movable claw reach the two sides of the blank blocked by the blocking plate. Then the convex ball descends vertically along the vertical rail, driving the sliding sleeve and the fixed claw to descend vertically. At this time, the docking gear is meshed with the clamping rack. Under the action of the clamping rack, the docking gear is driven to rotate, thereby driving the active friction wheel to rotate through the gear set, thereby driving the passive friction wheel and the worm to rotate, thereby through The worm drives the docking tooth and the movable claw to slide toward the fixed claw, and the blank is picked up by the movable claw and the fixed claw. At the same time, when the fixed claw descends, it will contact the lower pressure block, thereby driving the lower pressure block to descend. The descent of the lower pressure block will drive the rotating rod to rotate, thereby driving the rack slider to slide along the slide, and the slider spring is compressed, so that the clamping rack and the docking gear are disengaged, and the descent of the lower pressure block will drive the blocking plate to descend, and the blocking plate will no longer block the shelf. The conveying roller starts to convey the shelf, and the shelf will keep the blocking plate pressed down. Then the convex ball moves to the bottom of the vertical rail. At this time, the lifting cylinder is just extended to the farthest point, and then the lifting cylinder begins to contract, driving the convex ball to rise along the vertical rail. At this time, the sliding sleeve Vertical rise. At this time, since the shelf remains in a pressed down state, the clamping rack does not mesh with the docking gear. At this time, the fixed claw and the movable claw take and lift the blank, and then the convex ball enters the cross rail and enters the arc rail of the sliding track on the other side. At this time, the convex ball is at the highest point of the arc rail on the other side. At this time, the sliding sleeve and the fixed claw rotate 180 degrees, and the connecting frame slides in the semi-ring slide groove. At this time, the lifting electric cylinder is in a retracted state. At this time, the blank is above the processing block. Then the lifting electric cylinder starts to extend for the second time, driving the convex ball to descend along the arc rail and enter the vertical rail. At this time, the rack is released to mesh with the docking gear. Under the action of the loosened rack, the docking gear drives the movable claw to release the blank, and then the convex ball The ball descends vertically along the vertical rail. At this time, the blank enters between the inner fixed column and the processing block. When the fixed claw descends to contact the inclined block, the fixed claw pushes the inclined block, the blocking frame and the release rack to slide along the processing block, and the cross spring is compressed, so that the release rack is disengaged from the docking gear. When the blocking frame contacts the card block, the card block is pushed down along the upper slide groove through the slope of the card block. The downward pressure spring is compressed. When the blocking frame reaches the left side of the card block, the downward pressure spring rebounds, so that the card block clamps the blocking frame, so that the release rack and the docking gear remain disengaged. Then the lifting cylinder contracts, driving the convex ball to rise along the vertical rail to the cross rail, and then rotates 180 degrees back to the top of the arc rail on the initial side.

[0016] Preferably, the forging device also includes a processing block fixedly mounted on the processing frame, a transmission frame is arranged next to the processing frame, two conveying wheels are rotatably mounted on the transmission frame, conveying belts are wrapped around the two conveying wheels, and the externally docking gear drives the conveying wheels to rotate through a gear set, the gear set is composed of a plurality of gears and shafts, a column is fixedly mounted on the processing frame, a forging die is slidably mounted on the column, two pulleys are rotatably mounted on the processing frame, forging transmission belts are wrapped around the two pulleys, a lifting plate is fixedly mounted on the forging transmission belt, and the internally docking gear drives the pulleys to rotate through gear transmission.

[0017] Preferably, a lifting electric cylinder is fixedly installed on the transmission frame, a lifting block is fixedly installed on the top of the lifting electric cylinder, a lower mold is placed on the conveyor belt, and an engaging sleeve is fixedly installed on the lower mold. When the switch is pressed, the lifting electric cylinder extends to lift the lower mold and the inner fixed column on the conveyor belt into the processing block, and the engaging sleeve is formed after the billet forging is completed.

[0019] The rotation of the inner missing tooth gear drives the inner butt gear to rotate, which drives the pulley to rotate through the gear set, thereby driving the forging drive belt to move, thereby driving the lifting plate to move. The lifting plate first reaches the bottom to lift the forging die at the bottom, driving the forging die to rise to the highest point along the column, and then the inner missing tooth gear disengages from the inner butt gear, and the outer missing tooth gear begins to mesh with the outer butt gear. The outer missing tooth gear drives the outer butt gear to rotate, and drives the conveyor wheel to rotate through the gear set. When the outer butt gear disengages from the outer missing tooth gear, the conveyor belt drives the lower die to move forward one station, so that the lower die reaches the bottom of the processing frame. In this process, The fixed claw places the blank between the inner fixed column and the processing block and returns to the initial position, and lifts the electric cylinder to extend to drive the lower die to fit with the processing block and pause.

The plate is lifted through the forging die, and the forging die begins to descend along the column under the action of gravity. The blank is forged through the forging die to make it a meshing sleeve. Then the electric cylinder is lifted and begins to shrink. The lower die descends under the action of gravity, and the lower die, the inner fixed column and the meshing sleeve fall onto the conveyor belt. The conveyor belt is transported forward and leaves the device under the intermittent motion of the conveying wheel.

[0020] When the electric cylinder is lifted and retracted, the lower mold descends, and the upper ejector block descends along the lower slide groove under the action of gravity, and the clamping block descends along the upper slide groove. At this time, the clamping block leaves the right side of the blocking frame, and the cross spring rebounds to drive the blocking frame, the inclined block and the loosening rack to reset. When the next lower mold is lifted by the electric cylinder, the upper ejector block, the downward pressure spring and the clamping block rise at the same time and reach the left side of the blocking frame.

When the shelf 112 moves to the blocking plate 106, it will be blocked by the blocking plate 106. At this time, the conveying roller 103 can no longer drive the shelf 112 forward.

[0048] like Figure 6-Figure 11 As shown, the transfer device also includes a lifting electric cylinder 202 fixedly mounted on the electric cylinder frame 201, a connecting frame 213 is fixedly mounted on the top of the lifting electric cylinder 202, a fixing claw 206 is fixedly mounted on the sliding sleeve 205, a semi-ring slide groove 2061 is provided on the lower surface of the fixing claw 206, the connecting frame 213 slides in the semi-ring slide groove 2061, and a switch 203 is fixedly mounted on the electric cylinder frame 201.

[0049] like Figure 6-Figure 11 As shown, a picking mechanism is provided on the fixed claw 206, and the picking mechanism includes a docking gear 207 rotatably mounted on the fixed claw 206, an active friction wheel 208 and a passive friction wheel 209 are rotatably mounted on the fixed claw 206, a worm 210 is fixedly mounted on the passive friction wheel 209, the docking gear 207 drives the active friction wheel 208 to rotate through a gear set, the gear set is composed of gears and shafts, the active friction wheel 208 is meshed with the passive friction wheel 209, a movable claw 211 is slidably mounted on the fixed claw 206, the movable claw 211 is provided with a docking tooth 212, and the docking tooth 212 is meshed with the worm 210.

[0050] In the initial state, the convex ball 214 is located at the highest point of the arc rail 2041, and the lifting cylinder 202 is in the shortest state. When the cam 114 rotates and presses the switch 203, the lifting cylinder 202 retracts and contracts twice. The lifting cylinder 202 first extends, and drives the sliding sleeve 205 to descend along the fixed track column 204 through the connecting frame 213. The convex ball 214 moves along the arc rail 2041 to the vertical rail 2043. When the arc rail 2041 just enters the vertical rail 2043, the fixed claw 206 and the movable claw 211 reach the two sides of the blank 113 blocked by the blocking plate 106. Then the convex ball 214 descends vertically along the vertical rail 2043, driving the sliding sleeve 205 and the fixed claw 206 to descend vertically. At this time, the docking gear 207 and the clamping gear The gear 207 is meshed with the gear 208, and the gear 208 is driven to rotate by the clamping rack 120, thereby driving the active friction wheel 208 to rotate through the gear set, thereby driving the passive friction wheel 209 and the worm 210 to rotate, thereby driving the docking tooth 212 and the movable claw 211 to slide toward the fixed claw 206 through the worm 210, and the blank 113 is taken by the movable claw 211 and the fixed claw 206. At the same time, when the fixed claw 206 descends, it will contact the lower pressing block 122, thereby driving the lower pressing block 122 to descend. The descent of the lower pressing block 122 will drive the rotating rod 121 to rotate, thereby driving the rack slider 118 to slide along the slide 117, and the slider spring 119 is compressed, so that the clamping rack 120 is disengaged from the docking gear 207. The lower pressing block 122 descends, driving the blocking plate 106 to descend. The blocking plate 106 no longer blocks the shelf 112, and the conveying roller 103 begins to convey the shelf 112. The shelf 112 keeps the blocking plate 106 pressed down, and then the convex ball 214 moves to the bottom of the vertical rail 2043. At this time, the lifting cylinder 202 is just extended to the farthest point, and then the lifting cylinder 202 begins to contract, driving the convex ball 214 to rise along the vertical rail 2043. At this time, the sliding sleeve 205 rises vertically. At this time, since the shelf 112 remains pressed down, the clamping rack 120 does not mesh with the docking gear 207. At this time, the fixed claw 206 and the movable claw 211 take and lift the blank 113, and then the convex ball 214 enters the cross rail 2042 and Entering into the arc rail 2041 of the sliding track on the other side, the convex ball 214 is at the highest point of the arc rail 2041 on the other side. At this time, the sliding sleeve 205 and the fixed claw 206 rotate 180 degrees, and the connecting frame 213 slides in the semi-ring slide groove 2061. At this time, the lifting cylinder 202 is in a retracted state. At this time, the blank 113 is located above the processing block 303. Then the lifting cylinder 202 begins to extend for the second time, driving the convex ball 214 to descend along the arc rail 2041 and enter the vertical rail 2043. At this time, the rack 315 is released to mesh with the docking gear 207. Under the action of the loosened rack 315, the docking gear 207 drives the movable claw 211 to release the blank 113, and then the convex ball 214 vertically descends along the vertical rail 2043.At this time, the blank 113 enters between the inner fixed column 324 and the processing block 303. When the fixed claw 206 descends to contact the inclined block 314, the fixed claw 206 pushes the inclined block 314, the blocking frame 312 and the loosening rack 315 to slide along the processing block 303, and the transverse spring 313 is compressed, so that the loosening rack 315 is disengaged from the docking gear 207. When the blocking frame 312 contacts the card block 309, the card block 309 is pushed along the slope of the card block 309. As the upper slide 3031 descends, the downward spring 311 is compressed. When the blocking frame 312 reaches the left side of the block 309, the downward spring 311 rebounds, causing the block 309 to clamp the blocking frame 312, so that the release rack 315 and the docking gear 207 remain disengaged. Then the lifting cylinder 202 contracts, driving the convex ball 214 to rise along the vertical rail 2043 to the cross rail 2042, and then rotate 180 degrees to return to the top of the arc rail 2041 on the initial side.

A column 307 is fixedly mounted on the processing frame 301, and a forging die 308 is slidably mounted on the column 307. Two pulleys 320 are rotatably mounted on the processing frame 301, and a forging transmission belt 321 is wrapped around the two pulleys 320. A lifting plate 322 is fixedly mounted on the forging transmission belt 321, and an inner docking gear 319 drives the pulley 320 to rotate through gear transmission.

[0052] like Figure 12-16 As shown, a lifting electric cylinder 304 is fixedly installed on the transmission frame 302, a lifting block 305 is fixedly installed on the top of the lifting electric cylinder 304, a lower mold 306 is placed on the conveyor belt 317, and an engaging sleeve 323 is fixedly installed on the lower mold 306. When the switch 203 is pressed, the lifting electric cylinder 304 extends to lift the lower mold 306 and the internal fixed column 324 on the conveyor belt 317 into the processing block 303, and the engaging sleeve 323 is formed after the forging of the billet 113 is completed.

[0053] like Figure 12-16As shown, a release mechanism is provided on the processing block 303, and the release mechanism includes a blocking frame 312 slidably mounted on the processing block 303, a ramp block 314 and a loosening rack 315 are fixedly mounted on the blocking frame 312, a slope is provided on the ramp block 314, a transverse spring 313 is provided between the blocking frame 312 and the processing block 303, an upper slide groove 3031 and a lower slide groove 3032 are provided on the processing block 303, a clamping block 309 is slidably mounted in the upper slide groove 3031, and an upper ejector block 310 is slidably mounted in the lower slide groove 3032, a downward pressure spring 311 is provided between the upper ejector block 310 and the clamping block 309, and when the lower mold 306 is lifted, the lower mold 306 contacts the upper ejector block 310, and the downward pressure spring 311 is in an unstressed state.

[0054] The rotation of the inner toothless gear 110 drives the inner docking gear 319 to rotate, and drives the pulley 320 to rotate through the gear set, thereby driving the forging drive belt 321 to move, thereby driving the lifting plate 322 to move, and the lifting plate 322 first reaches the bottom to lift the forging die 308 located at the bottom, and drives the forging die 308 to rise to the highest point along the column 307, and then the inner toothless gear 110 disengages from the inner docking gear 319, and the outer toothless gear 111 begins to mesh with the outer docking gear 318, and the outer toothless gear 111 drives the outer docking gear 318 to rotate, and drives the conveying wheel 316 to rotate through the gear set, when the outer docking gear 318 disengages from the outer toothless gear 111, the conveying belt 317 drives the lower die 306 to advance one station, so that the lower die 306 reaches the bottom of the processing frame 301, and in this process, the fixed claw 206 will move the blank The material 113 is placed between the inner fixed column 324 and the processing block 303 and returns to the initial position. The electric cylinder 304 is lifted and extended to drive the lower die 306 to fit with the processing block 303 and pause. When the outer docking gear 318 is disengaged from the outer missing tooth gear 111, the inner missing tooth gear 110 begins to mesh with the inner docking gear 319 again. The plate 322 is lifted and passes through the forging die 308. The forging die 308 begins to descend along the column 307 under the action of gravity. The blank 113 is forged by the forging die 308, so that the blank 113 becomes the meshing sleeve 323. Then the electric cylinder 304 is lifted and begins to shrink. The lower die 306 descends under the action of gravity, and the lower die 306, the inner fixed column 324 and the meshing sleeve 323 fall onto the conveyor belt 317. The conveyor belt 317 is transported forward and leaves the device under the intermittent movement of the conveying wheel 316.

[0055] When the electric cylinder 304 is lifted and retracted, the lower mold 306 descends, and the upper ejector block 310 descends along the lower slide groove 3032 under the action of gravity, and the clamping block 309 descends along the upper slide groove 3031. At this time, the clamping block 309 leaves the right side of the blocking frame 312, and the cross spring 313 rebounds to drive the blocking frame 312, the inclined block 314 and the loosening rack 315 to reset. When the next lower mold 306 is lifted by the electric cylinder 304, it drives the upper ejector block 310, the downward pressure spring 311 and the clamping block 309 to rise at the same time and reach the left side of the blocking frame 312.

[0056] Working principle: the blank 113 to be processed is placed on the shelf 112, the bottom motor 104 rotates to drive the motor wheel 105 to rotate slowly, and the rotating column 108 is driven to rotate through the lower transmission belt 107, thereby driving the cam 114, the internal gear 109, the internal toothless gear 110 and the external toothless gear 111 to rotate, and the internal gear 109 drives the conveying roller 103 on the straight section of the conveying frame 102 to rotate through the gear set, and the shelf 112 and the blank 113 are conveyed by the conveying roller 103. In the turning section, the shelf 112 on the straight section is used to push the shelf 112 in front forward, and the blank 113 is heated by the heating tube 116 to facilitate subsequent forging operations. When the shelf 112 moves to the blocking plate 106, it will be blocked by the blocking plate 106. At this time, the conveying roller 103 can no longer drive the shelf 112 forward. In the initial state, the convex ball 214 is located at the highest point of the arc rail 2041, and the lifting cylinder 202 is in the shortest state. When the cam 114 rotates and presses the switch 203, the lifting cylinder 202 extends and retracts twice. The lifting cylinder 202 first extends, and drives the sliding sleeve 205 to descend along the fixed track column 204 through the connecting frame 213. The convex ball 214 moves along the arc rail 2041 to the vertical rail 2043. When the arc rail 2041 just enters the vertical rail 2043, the fixed claw 206 and the movable claw 211 reach the blocked plate 1. 06 blocks both sides of the blank 113, and then the convex ball 214 descends vertically along the vertical rail 2043, driving the sliding sleeve 205 and the fixed claw 206 to descend vertically. At this time, the docking gear 207 is meshed with the clamping rack 120. Under the action of the clamping rack 120, the docking gear 207 is driven to rotate, thereby driving the active friction wheel 208 to rotate through the gear set, thereby driving the passive friction wheel 209 and the worm 210 to rotate, thereby driving the docking tooth 212 and the movable claw 211 to slide toward the fixed claw 206 through the worm 210. The claw 211 and the fixed claw 206 take the blank 113. At the same time, when the fixed claw 206 descends, it will contact the lower pressing block 122, thereby driving the lower pressing block 122 to descend. The descent of the lower pressing block 122 will drive the rotating rod 121 to rotate, thereby driving the rack slider 118 to slide along the slide 117, and the slider spring 119 is compressed, so that the clamping rack 120 is disengaged from the docking gear 207, and the descent of the lower pressing block 122 will drive the blocking plate 106 to descend, and the blocking plate 106 no longer blocks the shelf 112, and the conveying roller 103 opens. The shelf 112 is transported, and the shelf 112 keeps the blocking plate 106 in a depressed state. Then the convex ball 214 moves to the bottom of the vertical rail 2043. At this time, the lifting cylinder 202 is just extended to the farthest point. Then the lifting cylinder 202 begins to shrink, driving the convex ball 214 to rise along the vertical rail 2043. At this time, the sliding sleeve 205 rises vertically. At this time, because the shelf 112 is kept in a depressed state, the clamping rack 120 does not mesh with the docking gear 207. At this time, the fixed claw 206 and the movable claw 211 take and lift the blank 113.Then the convex ball 214 enters the cross rail 2042 and enters the arc rail 2041 of the sliding track on the other side. At this time, the convex ball 214 is located at the highest point of the arc rail 2041 on the other side. At this time, the sliding sleeve 205 and the fixed claw 206 rotate 180 degrees, and the connecting frame 213 slides in the semi-ring slide groove 2061. At this time, the lifting cylinder 202 is in a retracted state. At this time, the blank 113 is located above the processing block 303. Then the lifting cylinder 202 begins to extend for the second time, driving the convex ball 214 to descend along the arc rail 2041 and enter the vertical rail 2043. At this time, the rack 315 is released to mesh with the docking gear 207. Under the action of the loosened rack 315, the docking gear 207 drives the movable claw 211 to release the blank 113. Then the convex ball 214 descends vertically along the vertical rail 2043. At this time, the blank 113 enters the inner fixed column 324 and the processing block 30 3, when the fixed claw 206 drops to contact the inclined plane block 314, the fixed claw 206 pushes the inclined plane block 314, the blocking frame 312 and the loosening rack 315 to slide along the processing block 303, and the cross spring 313 is compressed, so that the loosening rack 315 is disengaged from the docking gear 207. When the blocking frame 312 contacts the card block 309, the card block 309 is pushed down along the upper slide groove 3031 through the slope of the card block 309, and the downward pressure spring 311 is compressed. When the blocking frame 312 reaches the left side of the card block 309, the downward pressure spring 311 rebounds, so that the card block 309 blocks the blocking frame 312, so that the loosening rack 315 and the docking gear 207 remain disengaged. Subsequently, the lifting cylinder 202 contracts, driving the convex ball 214 to rise along the vertical rail 2043 to the cross rail 2042, and then rotates 180 degrees to return to the top of the arc rail 2041 on the initial side. The rotation of the inner toothless gear 110 drives the inner docking gear 319 to rotate, and drives the pulley 320 to rotate through the gear set, thereby driving the forging drive belt 321 to move, thereby driving the lifting plate 322 to move, and the lifting plate 322 first reaches the bottom to lift the forging die 308 at the bottom, and drives the forging die 308 to rise to the highest point along the column 307, and then the inner toothless gear 110 disengages from the inner docking gear 319, and the outer toothless gear 111 begins to mesh with the outer docking gear 318, and the outer toothless gear 111 drives the outer docking gear 318 to rotate, and drives the conveying wheel 316 to rotate through the gear set. When the outer butt-jointed gear 318 is disengaged from the outer tooth-missing gear 111, the conveyor belt 317 drives the lower die 306 forward one station, so that the lower die 306 reaches the bottom of the processing frame 301. During this process, the fixed claw 206 places the blank 113 between the inner fixed column 324 and the processing block 303, and returns to the initial position, and lifts the electric cylinder 304 to extend and drive the lower die 306 to fit the processing block 303, and pause. When the outer butt-jointed gear 318 is disengaged from the outer tooth-missing gear 111, the inner tooth-missing gear 110 starts to mesh with the inner butt-jointed gear 319 again, and the lifting plate 322 passes through the forging die 308.The forging die 308 begins to descend along the column 307 under the action of gravity, and the blank 113 is forged by the forging die 308, so that the blank 113 becomes the engaging sleeve 323. Then, the electric cylinder 304 is lifted and begins to shrink. The lower die 306 descends under the action of gravity, and the lower die 306, the inner fixed column 324 and the engaging sleeve 323 fall onto the conveyor belt 317. The conveyor belt 317 is transported forward and away from the device under the intermittent motion of the conveying wheel 316. When the lifting cylinder 304 contracts, the lower mold 306 descends, the upper ejector block 310 descends along the lower slide groove 3032 under the action of gravity, and the clamping block 309 descends along the upper slide groove 3031. At this time, the clamping block 309 leaves the right side of the blocking frame 312, and the horizontal spring 313 rebounds to drive the blocking frame 312, the inclined block 314 and the loosening rack 315 to reset. When the next lower mold 306 is lifted by the lifting cylinder 304, the upper ejector block 310, the downward pressure spring 311 and the clamping block 309 rise at the same time and reach the left side of the blocking frame 312.
