Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary persons in the art without creative work are within the scope of protection of the present invention.

[0028] Embodiment: A double-tube quenching automatic clamping and material distribution and conveying device.

[0029] Reference Figures 1 to 11 As shown, a double round tube quenching automatic clamping material distribution and conveying device comprises:

[0030] Round tube unloading mechanism 1 (refer to Figures 2 to 4As shown), the round tube unloading mechanism 1 includes a unloading rack 11, on which a plurality of steel tube placing brackets 12 are installed, which are spaced side by side in a transverse direction. The steel tube placing brackets 12 are tilted forward, so that the round tubes placed on the steel tube placing brackets 12 can always roll forward under the action of gravity, so as to facilitate the subsequent round tubes to be loaded one by one under the action of gravity. A plurality of blanking guide plates 13 are installed in front of the steel tube placing brackets 12, which are spaced side by side in a transverse direction. The top of the blanking guide plate 13 is arranged to be tilted forward, so as to facilitate the round tube to slide down naturally after entering the blanking guide plate 13. Each blanking guide plate 13 is provided with a strip hole 14 in the vertical direction, and a front movable cross bar 15 penetrates each blanking guide plate 13 in the transverse direction. The strip hole 14 and the moving cross bar push-pull cylinder 17 are installed in the vertical direction below the front moving cross bar 15 and are connected to the front moving cross bar 15. During actual operation, the front moving cross bar 15 can be driven to move up and down in the strip hole 14 of the blanking guide plate 13 by the moving cross bar push-pull cylinder 17. A plurality of front baffle plates 16 arranged side by side and spaced apart are installed horizontally on the front moving cross bar 15. The function of the front baffle plate 16 is to control the timing of the round tube entering the blanking guide plate 13. A rear baffle plate mounting cross bar 18 is installed on the discharging frame 11 at the oblique rear of the blanking guide plate 13. A plurality of rear baffle plates 19 arranged side by side and spaced apart are installed on the rear baffle plate mounting cross bar 18. The function of the rear baffle plate 19 is to stop the round tube from rolling downward from the steel pipe placing bracket 12. In actual work, the round tubes that need to be quenched are placed on the steel tube placing bracket 12 and blocked by the rear baffle plate 16. When loading is required, the moving crossbar push-pull cylinder 17 drives the front moving crossbar 15 to drive the front baffle plate 16 to move downward. When the front baffle plate 16 is lower than the position of the blanking guide plate 13, the round tubes fall into the subsequent round tube channel blanking conveying mechanism 2 along the blanking guide plate 13 under the action of gravity. When the moving crossbar push-pull cylinder 17 drives the front moving crossbar 15 to drive the front baffle plate 16 to the lowest position, the position of the front baffle plate 16 is lowered. When the rear baffle plate 19 is in position, a round tube on the rear baffle plate 19 is just above the front baffle plate 16, and then the moving cross bar push-pull cylinder 17 drives the front moving cross bar 15 to drive the front baffle plate 16 to move upward and reset, the round tube can be lifted up by the front baffle plate 16 and placed on the blanking guide plate 13. According to this cycle, the round tube can be automatically discharged one by one. Moreover, the round tube discharge mechanism 1 has a simple structure and makes full use of the round tube's own gravity to discharge one by one. There is no need to use manual labor or manipulators, and the discharge speed is fast and the efficiency is high.

A V-shaped groove for limiting the circular tube is provided on the top of each first circular tube support block 2234, and an inclined first partition plate 2235 is installed behind the first circular tube support block 2234. During actual operation, the first cylinder 2232 can drive the first support plate 2233 to drive the first circular tube support block 2234 to move up and down, and the V-shaped grooves provided on the tops of the plurality of first circular tube support blocks 2234 form a first blanking limiting channel for the circular tube.

The end of the flip plate 227 is hinged to the top of the pull rod 226, and the bottom of the pull rod 226 is hinged to the side plate 225.In actual operation, when the second cylinder 2242 drives the second support plate 2243 to drive the side plate 225 to move downward, the side plate 225 drives the flip plate 227 to rotate around the central rotation axis 228 through the pull rod 226, so that the front end of the flip plate 227 tilts up, and at this time, the round tube unloading mechanism 1 unloads the material, and the round tube is guided by the wedge-shaped guide frame 222 and falls into the first blanking limit channel formed by the V-shaped groove set on the top of the first round tube support block 2234 in the first blanking assembly 223; after the first round tube falls into the first blanking limit channel, the second cylinder 2242 drives the second support plate 2243 to drive the side plate 225 to move downward, and ... The cylinder 2242 drives the second support plate 2243 to drive the side plate 225 to reset. The side plate 225 drives the flip plate 227 to rotate around the central axis 228 through the pull rod 226, so that the flip plate 227 is reset. At this time, the round tube discharge mechanism 1 discharges again, and the round tube falls into the second blanking limit channel formed by the V-shaped groove on the top of the second round tube support block 2244 in the second blanking assembly 224, thereby completing the automatic blanking and separation of the two round tubes, and accurately falling into different limit channels.

The four synchronous lifting worm gears 236 are distributed in a square shape, and the synchronous drive motor 231 is installed on the input shaft of the first gearbox 232. The output shaft of the first gearbox 232 is connected to the input shaft of the second gearbox 234 through a driving rod 233, and the output shaft of the second gearbox 234 is connected to the synchronous lifting worm gear 236 through a synchronous connecting rod 235. The top of the worm of each synchronous lifting worm gear 236 is installed with a connecting flange 237. During actual operation, the first gearbox 232 is driven to rotate by the synchronous drive motor 231, and the first gearbox 232 drives the two second gearboxes 234 to rotate synchronously. Then, the two second gearboxes 234 can drive the four synchronous lifting worm gears 236 to rise and fall synchronously, and then the first conveyor belt device 24 installed above the first synchronous adjustment component 23 can be adjusted to move up and down stably to meet the transportation requirements of round tubes of different models.

[0034] Reference Fig.10As shown, the first conveyor belt device 24 includes an outer shell 241, and a plurality of lugs 244 are installed at the bottom of the outer shell 241. The outer shell 241 is connected to the connection flange 237 at the top of the synchronous lifting worm gear 236 in the first synchronous adjustment component 23 through the lugs 244.

In actual operation, the height position of the second conveyor belt device 33 can be stably adjusted by the second synchronous adjustment component 32, and when the round tube enters the annular conveyor belt provided on the second conveyor belt device 33, the annular conveyor belt drives the round tube to continuously move forward.

[0036] In order to better understand the present invention, the working steps of the present invention are explained as follows:

[0037] (1) The round tube discharging mechanism 1 discharges the materials one by one: the round tubes to be quenched are placed on the steel tube placing bracket 12 and blocked by the rear baffle plate 16. When loading is required, the moving crossbar push-pull cylinder 17 drives the front moving crossbar 15 to drive the front baffle plate 16 to move downward. When the front baffle plate 16 is lower than the position of the blanking guide plate 13, the round tubes fall into the subsequent round tube blanking conveying mechanism 2 along the blanking guide plate 13 under the action of gravity. When the moving crossbar push-pull cylinder 17 drives the front moving crossbar 15 to drive the front baffle plate 16 to the lowest position, the front baffle plate 16 is 6 is lower than the position of the rear baffle plate 19. At this time, a round tube located on the rear baffle plate 19 is just above the front baffle plate 16. Then the moving cross bar push-pull cylinder 17 drives the front moving cross bar 15 to drive the front baffle plate 16 to move upward and reset. The round tube can be lifted up by the front baffle plate 16 and placed on the blanking guide plate 13. According to this cycle, the round tube can be automatically discharged one by one. Moreover, the round tube discharging mechanism 1 has a simple structure and makes full use of the gravity of the round tube itself to discharge one by one. There is no need to use manual or mechanical arms, and the discharging speed is fast and the efficiency is high.

[0038] (2) Material separation and conveying of the round tube discharging mechanism 2: When the round tube in the round tube discharging mechanism 1 is discharged through the material discharging guide plate 13, the second cylinder 2242 drives the second support plate 2243 to drive the side plate 225 to move downward, and the side plate 225 drives the flip plate 227 to rotate around the central rotation axis 228 through the pull rod 226, so that the front end of the flip plate 227 is tilted. At this time, the round tube discharging mechanism 1 discharges the material, and the round tube is guided by the wedge-shaped guide frame 222 and falls into the first material discharging limit channel formed by the V-shaped groove set on the top of the first round tube support block 2234 in the first material discharging assembly 223; the first After the round tube falls into the first blanking limiting channel, the second cylinder 2242 drives the second support plate 2243 to drive the side plate 225 to reset, and the side plate 225 drives the flip plate 227 to rotate around the central shaft 228 through the pull rod 226, so that the flip plate 227 is reset. At this time, the round tube discharge mechanism 1 discharges again, and the round tube falls into the second blanking limiting channel formed by the V-shaped groove set on the top of the second round tube support block 2244 in the second blanking assembly 224 under the guidance of the flip plate 227, so that the two round tubes can be automatically blanked and divided, and fall into different limiting channels accurately. When the two round tubes fall into the first blanking limiting channel and the second blanking limiting channel respectively, that is, they just fall into two parallel and spaced annular conveyor belts 242, the two continuously circularly rotating annular conveyor belts 242 can drive the round tubes falling on the annular conveyor belts 242 to move forward and be transported to the round tube conveying mechanism 3.

[0039] (3) Forward conveying of the round tube conveying mechanism 3: After the round tube enters the annular conveyor belt provided on the second conveyor belt device 33, the two annular conveyor belts provided on the second conveyor belt device 33 can respectively drive the two round tubes to continuously move forward.

[0040] The double round tube quenching automatic clamping, dividing and conveying device is reasonably designed and simple in structure. It can realize automatic feeding, dividing and forward conveying of round tubes and can convey two round tubes at the same time, greatly improving the feeding and conveying efficiency of round tubes.
