Description

TECHNICAL FIELD

[0001] The present application relates to the technical field, in particular to an automatic forging production line of a bevel gear. BACKGROUND

[0002] The bevel gear is simply called a bevel gear, and the appearance is a disc ring shape, which is one of the important components of the drive axle transmission. At present, the production method of the bevel gear is to manufacture a formed bevel gear forging by upsetting, punching, hole expanding, ring rolling, swing rolling forming, and shaping processes, and then to complete the tooth shape of the bevel gear by polishing and milling. In the actual forging process of the bevel gear, workers generally transfer the bevel gear between the upsetting, punching, hole expanding, ring rolling, and swing rolling forming devices. In the transition time of manual transfer, the forging part will slowly cool down, so that the best forging temperature is lost. Therefore, the workers need to process the forging part in a short time, and need to heat or heat the forging part before processing, which not only makes the work of the workers heavy, but also prolongs the forging time, thereby reducing the forging efficiency of the bevel gear and increasing the forging cost.

[0007] By adopting the above technical scheme, when the bar is conveyed into the arc plate by the chain conveyor, the first push cylinder pulls the first push rod and the second push rod to move away from the high-frequency heating furnace, the first slider at the bottom of the feeding box moves with the second push rod, the second slider is hinged with the first slider by the second connecting rod, and the sliding directions of the two are perpendicular, so the second slider moves towards the arc plate under the pull of the first slider, the arc plate is hinged with the second slider by the third connecting rod at the bottom of the arc plate, and the arc plate turns downwards under the movement of the first slider, the bar on the arc plate slides into the feeding box, then the first push cylinder pushes the first push rod and the second push rod to move towards the high-frequency heating furnace, the push plate in the feeding box pushes the bar into the high-frequency heating furnace under the push of the first push rod, the first slider at the bottom of the feeding box moves with the second push rod, and the second slider moves away from the arc plate, so that the arc plate turns upwards to receive the bar conveyed by the chain conveyor again.

[0008] Further provided in the application is that the temperature detection and screening assembly comprises a pair of first chain wheels rotatably connected to the bar heating frame, a first chain installed on the first chain wheels, a first push plate fixed to the first chain, a pair of second chain wheels rotatably connected to the bar heating frame, a second chain installed on the second chain wheels, a second push plate fixed to the second chain, a temperature monitor arranged beside the outlet of the high-frequency heating furnace on the bar heating frame, a first slide fixedly arranged on the bar heating frame and located on the side of the first chain, and a collecting box arranged at the bottom of the first slide.

[0009] By adopting the above technical scheme, when the bar is conveyed into the arc plate by the chain conveyor, the first push cylinder pulls the first push rod and the second push rod to move away from the high-frequency heating furnace, the first slider at the bottom of the feeding box moves with the second push rod, the second slider is hinged with the first slider by the second connecting rod, and the sliding directions of the two are perpendicular, so the second slider moves towards the arc plate under the pull of the first slider, the arc plate is hinged with the second slider by the third connecting rod at the bottom of the arc plate, and the arc plate turns downwards under the movement of the first slider, the bar on the arc plate slides into the feeding box, then the first push cylinder pushes the first push rod and the second push rod to move towards the high-frequency heating furnace, the push plate in the feeding box pushes the bar into the high-frequency heating furnace under the push of the first push rod, the first slider at the bottom of the feeding box moves with the second push rod, and the second slider moves away from the arc plate, so that the arc plate turns upwards to receive the bar conveyed by the chain conveyor again.

[0010] The further arrangement of the present application is that the driving assembly comprises a driving motor fixed on the bar heating frame, a belt pulley and a bevel gear fixed on the output end of the driving motor, a rotating shaft fixedly inserted into the shaft hole of the belt pulley and rotating on the bar heating frame, a rotating shaft fixedly inserted into the shaft hole of the belt pulley and rotating on the bar heating frame, a belt pulley and a bevel gear sleeved on the rotating shaft and the rotating shaft respectively, the belt pulley and the belt pulley are driven by the belt, the bevel gear and the bevel gear are driven by the meshing, the rotating shaft and the belt pulley are connected by the one-way bearing, the rotating shaft and the bevel gear are connected by the one-way bearing, and the rotating direction of the one-way bearing and the one-way bearing is opposite.

[0011] By adopting the above technical scheme, when the driving belt pulley works, the driving motor drives the belt pulley and the bevel gear to rotate forward, the belt pulley drives the belt pulley through the belt, the belt pulley drives the rotating shaft through the one-way bearing, and the belt pulley drives the belt pulley to rotate, although the bevel gear drives the bevel gear through the meshing, but the rotating direction of the bevel gear and the one-way bearing is opposite, so the bevel gear cannot drive the rotating shaft and the belt pulley to rotate; when the driving belt pulley works, the driving motor drives the belt pulley and the bevel gear to rotate reversely, the bevel gear drives the bevel gear through the meshing, the bevel gear drives the rotating shaft through the one-way bearing, and the belt pulley drives the belt pulley to rotate, although the belt pulley can drive the belt pulley through the belt, but the rotating direction of the belt pulley and the one-way bearing is opposite, so the belt pulley cannot drive the rotating shaft and the belt pulley to rotate.

[0012] The further arrangement of the present application is that the inlet and the outlet of the heat preservation chamber are respectively hingedly installed with a cover and a cover, one end of the cover is fixedly installed with a gear, the inlet side of the heat preservation chamber is rotatably connected with a gear meshing with the gear, the heat preservation chamber is provided with a chute below the gear, the chute is slidably connected with a rack meshing with the gear, one end of the rack is fixedly connected with a baffle, one side of the baffle is rotatably connected with a rotating wheel in contact with a pushing plate, and the chute is provided with a spring at the other end of the rack.

[0013] By adopting the above technical scheme, when the pushing plate pushes the bar, the pushing plate pushes the baffle and the rack to move forward to compress the spring through the rotating wheel, the gear meshing with the rack drives the gear to rotate through the meshing, and the cover is turned up to open the channel for the bar to enter the heat preservation chamber, when the pushing plate returns to the initial position from the bottom of the belt pulley, the rack loses the pushing force of the pushing plate, and the compressed spring provides a certain reaction force to push the rack in the opposite direction, thereby restoring the state of the cover covering the inlet of the heat preservation chamber.

[0014] The further arrangement of the present application is that the bar blank discharging assembly comprises a chute two fixedly inclined on the bar blank heating frame, a turnover frame hingedly connected to the bar blank heating frame and located at the lower end of the chute two, a cylindrical box fixed on the turnover frame, a pressure sensor fixedly installed at the bottom of the cylindrical box, and a driving cylinder one driving the turnover frame to turn over; the upper end of the chute two is located at the outlet of the heat preservation chamber; the cylindrical box is located at the lower end of the chute two to receive the bar blank; the cylinder body of the driving cylinder one is hingedly connected to the bar blank heating frame; and the output end of the driving cylinder is hingedly connected to the turnover frame.

[0015] By adopting the above technical scheme, when the bar blank is pushed out of the heat preservation chamber, it will fall into the upper end of the chute two and slide into the cylindrical box at the lower end of the chute two. At this time, the pressure sensor at the bottom of the cylindrical box senses the pressure of the bar blank, and the driving cylinder one drives the turnover frame to turn over downward, and the cylindrical box and the bar blank will turn over with it. When the bar blank changes from the inclined state to the vertical state, the driving cylinder will stop the turnover frame from turning over. Since the hydraulic punching machine mainly punches the bar blank in the horizontal direction, the mechanical hand can quickly put the bar blank in the hydraulic punching machine for processing by clamping the bar blank in this state, thereby shortening the transition time. Finally, since the bar blank is taken away, the pressure sensor at the bottom of the cylindrical box senses the change of the pressure, and the driving cylinder one drives the turnover frame to turn over upward again, and the cylindrical box will return to the initial position to receive the subsequent bar blank and adjust the posture.

[0016] The further arrangement of the present application is that a support is fixedly arranged on the chute two, a buffer plate is hingedly connected above the support, a deceleration chain is hung on the support, and the deceleration chain is arranged on the buffer plate and the chute.

[0017] By adopting the above technical scheme, the weight of the buffer plate and the deceleration chain can slow down the falling speed of the bar blank on the chute two to some extent, thereby reducing the impact of the bar blank on the cylindrical box and the turnover frame, so as to avoid that the bar blank impacts too large and damages the structure of the driving cylinder one and the pressure sensor.

[0018] The further arrangement of the present application is that the tooth clamping assembly one comprises a clamping frame one fixed on the output end of the mechanical hand, a pair of clamping jaws hingedly connected to the clamping frame one, a driving cylinder two fixed on the clamping frame one, and a connecting rod four hingedly connected to the output end of the driving cylinder two and the clamping jaws at two ends; the two clamping jaws are crossed with each other, and the crossing point is located at the hinge center of the two clamping jaws; and the two connecting rods are symmetrical with each other, one end of each connecting rod is commonly hingedly connected to the output end of the driving cylinder two, and the other end of each connecting rod is respectively hingedly connected to one end of the clamping jaws.

[0019] By adopting the above technical scheme, when the manipulator needs to clamp the forged piece, firstly, the driving cylinder two on the clamping frame one pushes the hinge centers of the two connecting rods four and the four-directional clamping jaws to close, so as to open the included angle between the two connecting rods four, and the clamping jaws hinged to one end of the connecting rod four are also opened to the appropriate angle, so as to prepare for clamping the forged piece, then the driving cylinder two pulls the two connecting rods four away from the hinge centers of the clamping jaws, so as to reduce the included angle between the two connecting rods four, and the clamping jaws are also reduced at the same time, and then the two sides of the forged piece are clamped and fixed.

[0020] Further provided by the present application is that the tooth clamping assembly two comprises a turnover arm hinged to the vertical ring rolling machine, three clamping frames two uniformly extending around the turnover arm, a long slot formed on the clamping frame two, a sliding block three sliding on the long slot, a clamping plate fixed on the sliding block three and penetrating through the long slot, a driving cylinder three fixedly installed on the turnover arm, a lifting seat fixedly connected to the output end of the driving cylinder three, a connecting rod five having two ends hinged to the lifting seat and the sliding block three respectively, a driving motor two for driving the turnover arm to turn, a worm gear reduction motor fixedly installed at the output end of the driving motor two, and a hinge center shaft of the turnover arm fixedly connected to the output end of the worm gear reduction motor.

[0021] By adopting the above technical scheme, when the forged piece with a small hole is processed in the hydraulic punch, the mechanical hand is clamped by the tooth clamping assembly one, and can only clamp the two sides of the forged piece in the horizontal direction from the inside of the hydraulic punch. Since the working principle of the vertical ring rolling machine is to put the heated forged piece with a small hole on the core roller of the ring rolling machine, drive it to rotate by the outer edge of the ring rolling machine pressure roller, and then use two obliquely downward and symmetrical cylinders to drive the output end of the roll holder to contact and position the outer side wall of the forged piece, thereby realizing the effect of reducing the thickness and expanding the diameter of the forged piece, therefore, the mechanical hand must adjust its clamping posture to clamp the forged piece in the horizontal direction, and then put it into the core roller of the vertical ring rolling machine. In the present scheme, the ring-shaped forged piece is first clamped on the turnover arm by the mechanical hand before entering the vertical ring rolling machine for processing. At this time, the driving cylinder three drives the lifting seat to move away from the turnover arm. The two ends of the connecting rod are hinged to the lifting seat and the sliding block three, respectively. Therefore, the clamping plates of the three clamping frames two will move towards the center of the forged piece, so as to clamp and fix the forged piece. Then, the driving motor two drives the turnover arm to turn and approach the core shaft of the vertical ring rolling machine. When the turnover arm turns to one end of the core shaft, the forged piece clamped on the turnover arm will be exactly put on the core shaft. At this time, the driving cylinder three is started again to drive the clamping plates to move away from the forged piece, and the spacing between the three clamping plates and the forged piece is expanded, so as to facilitate the ring rolling of the forged piece. Although the three clamping frames two are also close to the vertical ring rolling machine due to the turning of the turnover arm, the three clamping frames two are evenly distributed around the turnover arm, and are located in the gap between the ring rolling machine pressure roller and the two roll holders. Therefore, the clamping plates and the clamping frames two close to the vertical ring rolling machine will not affect the working of the ring rolling machine, and can clamp out the forged piece with an expanded hole after the ring rolling machine finishes processing. Finally, the driving motor two drives the turnover arm to turn to the initial position again, and releases the fixation of the clamping plates at the same time. The rear mechanical hand continues to clamp the processed forged piece in the horizontal direction, so as to quickly send it into the swing rolling machine for processing.

[0022] The present application further provides that the lifting seat is fixedly connected with a plurality of Z-shaped lifting rods, which are evenly distributed in the gap between the three clamping frames two and the turnover arm.

[0023] By adopting the above technical scheme, when the forged piece is processed in the vertical ring rolling machine, it will be clamped and fixed by the clamping plates on the turnover arm, and will be turned out of the vertical ring rolling machine with the turnover arm. At this time, the driving cylinder three drives the lifting seat to move towards the turnover arm, so as to open the clamping plates of the forged piece. At the same time, the lifting rods on the lifting seat will pass through the gap of the clamping frames two, lift the forged piece placed on the turnover arm, so as to facilitate the horizontal clamping of the forged piece by the mechanical hand, and at the same time, weaken the influence of the clamping plates on the clamping work of the tooth clamping assembly one.

[0024] The beneficial effects of the present application are:

[0025] 1. Through the production line, not only can each forging link of the tooth be automatically and quickly performed instead of manual work, but also the transition time between each link is shortened, thereby improving the forging efficiency of the tooth while avoiding excessive temperature loss of the tooth, which leads to an increase in the forging process and a time extension.

[0026] 2. Through the structure of the bar feeding assembly, not only can the bar be automatically fed into the high-frequency heating furnace body, but also the connecting structure of the sliding block and the connecting rod fully utilizes the pushing force of the pushing cylinder to achieve the two functional effects of pushing plate pushing and circular arc plate overturning, thereby reducing the driving equipment and saving certain energy costs.

[0027] 3. Through the temperature detection and screening assembly, not only can the bar with a suitable heating temperature be automatically screened, but also the driving assembly fully utilizes the rotating force of the driving motor to achieve the two functional effects of conveying the bar and rejecting the bar, thereby reducing the driving equipment and saving certain energy costs.

[0028] 4. Through the flip cover one and the upper gear and rack transmission structure of the heat preservation chamber, not only can the automatic opening and closing effect of the flip cover one be achieved by using the power of the pushing plate one, but also the bar can be sent into the heat preservation chamber for heat preservation by the pushing plate one to avoid heat loss of the bar.

[0029] 5. Through the bar discharging assembly, not only can the bar discharged from the heat preservation chamber be received, but also the position state of the bar can be automatically adjusted, thereby facilitating the work of the mechanical hand while shortening the transition time between the bar in the heat preservation chamber and the hydraulic punch press to reduce the temperature loss.

[0030] 6. Through the structures of the tooth clamping assembly one and the tooth clamping assembly two, not only can the forged parts be quickly taken and placed in different processing equipment, but also the two can work together to adapt to the taking and placing work of different processing postures and angles between the equipment, thereby further improving the forging efficiency of the tooth and reducing the temperature loss.

[0044] As shown in the figure, Figure 1 , Figure 2As shown, the bar feeding assembly 13 comprises a feeding box 131 fixedly inclined on the bar conveyor frame 1, a pushing cylinder 132 fixed on the bar conveyor frame 1 and located at one side of the lower end of the feeding box 131, a pushing rod one 133 and a pushing rod two 134 both fixedly parallel on the output end of the pushing cylinder 132, an arc plate 135 hingedly connected to the upper end of the feeding box 131, a connecting rod one 136 fixed to the bottom of the arc plate 135, a sliding block one 137 and a sliding block two 138 both slidingly located at the bottom of the feeding box 131 and perpendicular to each other, a connecting rod two 138a hingedly connected to the two ends of the sliding block one 137 and the sliding block two 138, and a connecting rod three 139 hingedly connected to the connecting rod one 136 and the sliding block two 138. The pushing rod one 133 passes through one side of the feeding box 131, and one end of the pushing rod one 133 penetrating into the feeding box 131 is fixedly connected with a pushing plate 133a. The pushing rod two 134 is located at the bottom of the feeding box 131 and fixedly connected with the sliding block one 137. The upper end of the feeding box 131 is close to the chain conveyor 11, and the arc plate 135 is opposite to one end of the chain conveyor 11. The lower end of the feeding box 131 is close to the inlet of the high-frequency heating furnace 21, and one side of the lower end of the feeding box 131 is provided with an opening communicating with the inlet of the high-frequency heating furnace 21. The pushing plate 133a is opposite to the opening of the feeding box 131. When the bar is conveyed by the chain conveyor 11 into the arc plate 135, the pushing cylinder 132 first pulls the pushing rod one and the pushing rod two 134 to move away from the high-frequency heating furnace 21. The sliding block one 137 at the bottom of the feeding box 131 moves with the pushing rod two 134. Since the connecting rod two 138a is hingedly connected between the sliding block one 137 and the sliding block two 138 and the sliding directions of the two are perpendicular, the sliding block two 138 moves towards the arc plate 135 under the pulling of the sliding block one 137.

Then the pushing cylinder 132 pushes the pushing rod one 133 and the pushing rod two 134 to move towards the high-frequency heating furnace 21. The pushing plate 133a in the feeding box 131 pushes the bar into the high-frequency heating furnace 21 from the opening of the feeding box 131 under the pushing of the pushing rod one 133. At the same time, the sliding block one 137 at the bottom of the feeding box 131 moves with the pushing rod two 134 and the sliding block two 138 moves away from the arc plate 135, so that the arc plate 135 turns upwards to receive the bar conveyed by the chain conveyor 11 again.

[0046] As Figure 3 , Figure 4The shown driving assembly 24 comprises a driving motor 241 fixed on the bar heating frame 2, two belt pulleys 242 and bevel gears 243 fixedly installed on the output end of the driving motor 241, a rotating shaft 244 fixedly inserted into the shaft hole of the chain wheel 231 and rotating on the bar heating frame 2, a rotating shaft 247 fixedly inserted into the shaft hole of the chain wheel 233 and rotating on the bar heating frame 2, two belt pulleys 245 and bevel gears 248 respectively sleeved on the rotating shaft 244 and the rotating shaft 247, a belt transmission between the belt pulley 242 and the belt pulley 245, a meshing transmission between the bevel gear 243 and the bevel gear 248, a one-way bearing 246 installed at the connection between the rotating shaft 244 and the belt pulley 245, a one-way bearing 249 installed between the rotating shaft 247 and the bevel gear 248, the rotating directions of the one-way bearing 246 and the one-way bearing 249 being opposite, when the driving chain wheel 231 works, the driving motor 241 drives the belt pulley 242 and the bevel gear 243 to rotate forward, wherein the belt pulley 242 drives the belt pulley 245 through the belt transmission, the belt pulley 245 drives the rotating shaft 244 through the one-way bearing 246, thereby driving the chain wheel 231 to rotate, although the bevel gear 243 drives the bevel gear 248 through the meshing transmission, the bevel gear 248 cannot drive the rotating shaft 247 and the chain wheel 233 to rotate because the rotating direction of the bevel gear 248 is opposite to the rotating direction of the one-way bearing 249; when the driving chain wheel 233 works, the driving motor 241 drives the belt pulley 242 and the bevel gear 243 to rotate reversely, wherein the bevel gear 243 drives the bevel gear 248 through the meshing transmission, the bevel gear 248 drives the rotating shaft 244 through the one-way bearing 249, thereby driving the chain wheel 233 to rotate, although the belt pulley 242 can drive the belt pulley 245 through the belt transmission, the belt pulley 245 cannot drive the rotating shaft 244 and the chain wheel 231 to rotate because the rotating direction of the belt pulley 245 is opposite to the rotating direction of the one-way bearing 246.

[0047] As Figure 1 , as Figure 5As shown, the entrance and exit of the heat preservation chamber 22 are respectively hingedly installed with the cover one 221 and the cover two 222, one end of the hinge of the cover one 221 is fixedly installed with the gear one 223, the heat preservation chamber 22 is rotatably connected with the gear two 224 which engages with the gear one 223 at the side of the entrance of the heat preservation chamber 22, the heat preservation chamber 22 is located below the gear two 224 and is provided with the sliding groove 225, the sliding groove 225 is slidably connected with the rack 226 which engages with the gear two 224, one end of the rack 226 is fixedly connected with the baffle 227, one side of the baffle is rotatably connected with the rotating wheel 228 which is in contact with the pushing plate one 232a, the other end of the sliding groove 225 is installed with the spring 229, when the pushing plate one 232a pushes the bar, the pushing plate one 232a will push the baffle and the rack 226 to move forward and compress the spring 229 through the rotating wheel 228, and the gear two 224 which engages with the rack 226 will engage with the transmission gear one 223 to rotate, and then drive the whole cover one 221 to turn up and open the channel for the bar to enter the heat preservation chamber 22, when the pushing plate one 232a rounds back to the initial position from the bottom of the sprocket two 233, the rack 226 will lose the thrust of the pushing plate one 232a, and the compressed spring 229 will provide a certain counter force to push the rack 226 to move in the opposite direction, and then restore the state that the cover one 221 covers the entrance of the heat preservation chamber 22.

[0048] As Figure 1 , as Figure 6As shown, the bar blanking assembly 25 includes a chute two 251 fixedly inclined on the bar heating rack 2, a turnover frame 252 hingedly connected to the bar heating rack 2 and located at the lower end of the chute two 251, a cylindrical box 253 fixed on the turnover frame 252, a pressure sensor 254 fixed on the turnover frame 252 and located at the bottom of the cylindrical box 253, a drive cylinder one 255 for driving the turnover frame 252 to turn over, the upper end of the chute two 251 is located at the outlet of the holding chamber 22, the cylindrical box 253 is located at the lower end of the chute two 251 to receive the material, the cylinder body of the drive cylinder one 255 is hingedly connected to the bar heating rack 2, and the output end of the drive cylinder is hingedly connected to the turnover frame 252. When the bar blank is pushed out of the holding chamber 22, it will fall into the upper end of the chute two 251 and slide into the cylindrical box 253 at the lower end of the chute two 251. At this time, the pressure sensor 254 at the bottom of the cylindrical box 253 senses the pressure of the bar blank, and the drive cylinder one 255 drives the turnover frame 252 to turn over downward, and the cylindrical box 253 and the bar blank will turn over with it. When the bar blank changes from an inclined state to a vertical state, the drive cylinder stops the turnover frame 252 from turning over. Since the hydraulic punch 3 mainly punches the bar blank in the horizontal direction, the robot 6 can quickly put the bar blank in the hydraulic punch 3 for processing by clamping the bar blank in this state, thereby shortening the transition time. Finally, since the bar blank is taken away, the pressure sensor 254 at the bottom of the cylindrical box senses the change in pressure, and the drive cylinder one 255 drives the turnover frame 252 to turn over upward, and the cylindrical box 253 will return to the initial position to receive the subsequent bar blank and adjust the posture.

[0049] A support 256 is fixedly arranged on the chute two 251, the support 256 is hingedly connected with a buffer plate 257 above the chute two 251, a deceleration chain 258 is hung on the support 256, and the deceleration chain 258 is arranged on the buffer plate 257 and the chute. The weight of the buffer plate 257 and the deceleration chain 258 can slow down the falling speed of the bar blank on the chute two 251 to some extent, thereby reducing the impact of the bar blank on the cylindrical box 253 and the turnover frame 252, so as to avoid excessive impact of the bar blank and damage the structure of the drive cylinder one 255 and the pressure sensor 254.

[0050] As shown in the drawings, Figure 7As shown, the tooth clamping assembly one 61 includes a clamping frame one 611 fixed to the output end of the manipulator 6, a pair of clamping jaws 612 hinged to the clamping frame one 611, a driving cylinder two 613 fixed to the clamping frame one 611, two connecting rods four 614 hinged to the output end of the driving cylinder two 613 and one end of the clamping jaws 612, the two clamping jaws 612 cross each other with the intersection point located at the hinge center of the two clamping jaws 612, and the two connecting rods four 614 are symmetrical to each other with one end hinged to the output end of the driving cylinder two 613 and the other end hinged to one end of the clamping jaws 612 respectively. When the manipulator 6 needs to clamp the forged piece, the driving cylinder two 613 on the clamping frame one 611 first pushes the two connecting rods four 614 to move towards the hinge center of the clamping jaws 612, so as to open the included angle between the two connecting rods four 614, and the clamping jaws 612 hinged to one end of the connecting rods four 614 are also opened to the appropriate angle to prepare for clamping the forged piece. Then the driving cylinder two 613 pulls the two connecting rods four 614 away from the hinge center of the clamping jaws 612, so as to reduce the included angle between the two connecting rods four 614, and the clamping jaws 612 are also reduced at the same time, thereby clamping and fixing the two sides of the forged piece.

[0051] As shown, Figure 8 The tooth clamping assembly two 41 includes a turnover arm 411 hinged to the vertical ring rolling machine 4, three clamping frames two 412 uniformly extending around the turnover arm 411, a long slot 412a opened on the clamping frame two 412, a sliding block three 413 sliding in the long slot 412a, a clamping plate 413a fixed to the sliding block three 413 and passing through the long slot 412a, a driving cylinder three 414 fixedly installed on the turnover arm 411, a lifting seat 415 fixedly connected to the output end of the driving cylinder three 414, a connecting rod five 416 hinged to the lifting seat 415 and the sliding block three 413 at both ends, a driving motor two 417 for driving the turnover arm 411 to turn, a worm gear speed reducer motor 419 fixedly installed at the output end of the driving motor two 417, and the hinge center shaft of the turnover arm fixedly connected to the output end of the worm gear speed reducer motor 419. The clamping plate 413a is located on one side of the turnover arm 411 facing the vertical ring rolling machine 4, and the driving cylinder three 414 is located on the other side of the turnover arm 411.

[0052] When the forged piece with a small hole is finished in the hydraulic punch, the mechanical arm 6 is clamped by the tooth clamping assembly 61, which can only clamp the two sides of the forged piece in the horizontal direction from the inside of the hydraulic punch 3. Since the working principle of the vertical ring rolling machine 4 is to put the heated forged piece with a small hole on the core roller of the ring rolling machine, drive it to rotate by the outer edge of the ring rolling machine pressure roller, and then use two obliquely downward and symmetrical cylinders to drive the output end of the roll holder to contact and position the outer wall of the forged piece, thereby achieving the effect of reducing the thickness and expanding the diameter of the forged piece, therefore the mechanical arm 6 must adjust its clamping posture to be able to be sleeved into the core roller of the vertical ring rolling machine 4. In this scheme, the annular forged piece will be first clamped on the turnover arm 411 by the mechanical arm 6 before entering the vertical ring rolling machine 4 for processing. At this time, the driving cylinder three 414 drives the lifting seat 415 to move away from the turnover arm 411. The two ends of the connecting rod are hinged to the lifting seat 415 and the sliding block three 413 respectively, so that the clamping plates 413a of the three clamping frames two 412 will move towards the center of the forged piece, thereby clamping and fixing the forged piece. Then the driving motor two 417 drives the turnover arm 411 to turn and approach the core shaft of the vertical ring rolling machine 4. When the turnover arm 411 turns to one end of the core shaft, the forged piece clamped on the turnover arm 411 will be sleeved on the core shaft. At this time, the driving cylinder three 414 is started again to drive the clamping plates 413a to move away from the forged piece, and the spacing between the three clamping plates 413a and the forged piece is enlarged to facilitate the ring rolling of the forged piece. Although the three clamping frames two 412 will also be close to the vertical ring rolling machine 4 due to the turning of the turnover arm 411, the three clamping frames two 412 are evenly distributed around the turnover arm 411 and are located in the gap between the ring rolling machine pressure roller and the two roll holders. Therefore, the clamping plates 413a and the clamping frames two 412 attached to the vertical ring rolling machine will not affect the work of the ring rolling machine, and the forged piece with an expanded hole can be clamped out after the ring rolling machine finishes processing. Finally, the driving motor two 417 drives the turnover arm 411 to turn to the initial position again, and the clamping plates 413a are released at the same time. The rear mechanical arm 6 then continues to clamp the processed forged piece in the horizontal direction to quickly send it into the swing rolling machine 5 for processing.

[0053] The lifting seat 415 is fixedly connected with a plurality of lifting rods 418, which are uniformly distributed in the gap between the three clamping racks two 412 and the turnover arm 411. When the forging is finished in the vertical ring rolling machine 4, it will be clamped and fixed by the clamping plate 413a on the turnover arm 411 and turned out of the vertical ring rolling machine 4 with the turnover arm 411. At this time, the driving cylinder three 414 drives the lifting seat 415 to move towards the turnover arm 411, so as to open the clamping plate 413a of the old forging, and at the same time, the lifting rods 418 on the lifting seat 415 will pass through the gap of the clamping rack two 412, lift the forging placed on the turnover arm 411, so as to facilitate the mechanical hand 6 to quickly horizontally clamp the forging, and at the same time, weaken the influence of the clamping plate 413a on the clamping rack two on the clamping work of the tooth clamping assembly one 61.
