As shown in Figures 1-6, a fully automatic cutting pipeline includes a silo 1 for storing workpieces to be processed, a shot blasting machine 2, a pipe cutting and forming machine 3, a feeding transfer mechanism 4 and a discharging transfer mechanism 5 , the two ends of the shot blasting machine 2 are respectively provided with a shot peening feeding roller table 6 and a shot peening discharging roller table 7, and the feeding transfer mechanism 4 can transfer the workpiece located at the silo 1 to the shot peening feeding roller table 6. The workpiece is sent into the shot blasting machine 2 by the shot peening feeding roller table 6, and the discharge transfer mechanism 5 can transfer the workpiece on the shot peening and discharging roller table 7 to the pipe cutting and forming machine 3 for cutting operation.

The present application reduces labor costs by adopting a pipe cutting production line with a high level of automation, greatly reduces safety risks in the production process, and has high production efficiency. In addition, by adding a shot blasting machine 2 in front of the pipe cutting and forming machine 3, the reliability and durability of the workpiece are improved. The shot peening machine 2 used in this application has the function of automatic discharging, such as the Chinese patent with the announcement number CN101288946B and the announcement number CN205996820U, the shot peening machine 2 can automatically discharge after the shot peening operation, so that the workpiece is shot After the operation, it moves towards the discharge roller table.

Further, the feeding transfer mechanism 4 and the discharging transfer mechanism 5 both include several uprights 8, the upper ends of several uprights 8 are provided with the same fixed frame 9, and the fixed frame 9 is slidably connected with a movable beam 10, and the movable beam 10. A drive member (not shown in the drawings) that can drive the movable beam 10 to move on the fixed frame 9 is provided on one side of the frame. The movable beam 10 is provided with a grabbing member 11 that can clamp or put down the workpiece.

The movement process of the feeding transfer mechanism 4 is as follows: when the movable beam 10 moves to the top of the silo 1 , the grabbing member 11 can grab the workpiece located in the silo 1 at this time. Next, under the action of the driving member, the movable beam 10 drives the grasped workpiece to move toward the shot peening feeding roller table 6 , and transfers the workpiece to the shot peening feeding roller table 6 .

The movement process of the discharge transfer mechanism 5 is similar to the above, and is to transfer the workpiece at the shot blasting discharge roller table 7 to the pipe cutting and forming machine 3 .

Further, the grasping member 11 includes two mutually independent clamping jaws 12 , and the upper end surface of each clamping jaw 12 is provided with a movable arm 13 , and both movable arms 13 are slidably connected to the same movable beam 10 . The movable beam 10 is provided with a driving mechanism 14 that can simultaneously drive the two movable arms 13 to move vertically in a direction perpendicular to the ground.

The workpiece described in the present application is a steel pipe with a relatively long length, so two clamping jaws 12 are provided to ensure better stability during transport. In addition, a driving mechanism 14 is used to simultaneously move the two movable arms 13 up and down in a direction perpendicular to the ground, and by combining with the gripper 12, it is beneficial to grip and put down the target.

Further, the drive mechanism 14 includes a servo motor 15 located between the two movable arms 13, the output end of the servo motor 15 is provided with a servo right-angle steering gear 16, and one side of the servo right-angle steering gear 16 is provided with a rotating shaft 17, Both ends of the rotating shaft 17 are provided with gears 18 . The sides of the two movable arms 13 that are close to each other are provided with racks 19 that can engage with the gears 18 , and each rack 19 is arranged along the length direction of the movable arms 13 .

Specifically, the power output direction of the servo motor 15 is converted by the servo right-angle steering gear 16 to drive the horizontally arranged rotating shaft 17 for transmission, thereby driving the movable arm 13 to be perpendicular to the ground through the cooperative action of the gear 18 and the rack 19 direction to move up and down. The above-mentioned movement mode realizes that only one driving source can complete the synchronous movement of the two mutually independent movable arms 13 .

In addition, the meshing effect between the rack 19 and the gear 18 has the effect of stopping and limiting the position. When the gear 18 does not rotate, the position of the rack 19 will be synchronously limited, so that the movable arm 13 will not move in the vertical direction.

Further, a vertical guide rail 20 is provided on the side of each movable arm 13 away from the rack 19, and the movable beam 10 is provided with a chute (not shown in the drawings) that can be matched with the vertical guide rail 20. Through the cooperation between the vertical guide rail 20 and the chute, the movable arm 13 can only perform vertical movement, but cannot move left and right, so as to ensure the stability of the movement process.

Further, both ends of the rotating shaft 17 are sleeved with a bearing seat 21 , and each bearing seat 21 is fixedly connected with the movable beam 10 . Through the arrangement of the bearing seat 21 , the rotating shaft 17 can be limited to prevent the gear 18 from being separated from the rack 19 during use, so as to improve the stability of the transmission process. Second, the rotation efficiency of the rotating shaft 17 is improved, and the transmission efficiency is improved.

Further, both the shot peening feeding roller table 6 and the shot peening discharging roller table 7 include a frame 22, and the frame 22 is provided with a traveling conveying member 23 for driving the workpiece to move forward step by step. The number of the traveling conveying member 23 is There are several and are arranged in sequence along the length direction of the rack 22 . One end of each traveling conveying member 23 is provided with the same synchronous transmission mechanism (not shown in the drawings), and the synchronous transmission mechanism can synchronously drive several traveling conveying members 23 to operate.

When the workpiece is transferred from the feeding transfer mechanism 4 to several traveling conveying members 23, the traveling conveying members 23 are running at this time, and the workpiece is driven to move forward gradually by the action of frictional force. It should be noted that: the synchronous transmission mechanism is in the prior art, and can be the cooperation between the synchronous wheel and the synchronous transmission belt, which will not be described in detail here.

Further, each traveling conveying member 23 includes a roller 24, and one side of the roller 24 is coaxially provided with four circular platforms 25, and the four circular platforms 25 are in face-to-face contact, and any two adjacent circular platforms 25 Symmetrically arranged to form a concave-convex corrugated shape, one end of each roller 24 is matched with a synchronous transmission mechanism.

The four circular platforms 25 are face-to-face to form a concave-convex corrugated shape, which plays a role in correcting the direction of the workpiece during the transmission process. In addition, the grooves formed on the face of the circular table 25 can be matched with the workpiece.

Further, each traveling conveying member 23 is obliquely installed on the frame 22 , so that each traveling conveying member 23 forms an inclined angle with the length direction of the frame 22 . The angle of inclination can be acute or obtuse.

Through the inclined arrangement, the circular table 25 is also inclined synchronously, which in turn increases the contact area between the circular table 25 and the workpiece, which is beneficial to improve the speed of conveying the workpiece.

The present application also provides another way, that is, the shot blasting machine 2 does not need to have a self-discharging function, as long as the length of the workpiece is long enough and greater than the length of the shot blasting machine 2 itself. The traveling conveying member 23 on the shot peening feeding roller table 6 and the shot peening discharging roller table 7 takes over and cooperates, so as to gradually drive the workpiece to move.

Further, the number of pipe cutting and forming machines 3 is two, and a cleaning machine 26 is arranged between the two pipe cutting and forming machines 3, and both ends of the cleaning machine 26 are respectively provided with a first belt conveyor 27 and a second belt conveyor. 28. The discharge transfer mechanism 5 can also transfer the workpieces cut on the pipe cutting and forming machine 3 to the first belt conveyor 27 , and automatically cleaned by the cleaning machine 26 , and finally discharged by the second belt conveyor 28 .

Since the workpiece after the operation of the pipe cutting and forming machine 3 has metal chips on the surface, it needs to be cleaned and discharged.

The specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to the present embodiment without creative contribution as needed after reading this specification, but only in the claims of the present invention are protected by patent law.
