DETAILED DESCRIPTION

[0021] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] See also Figure 1 good Figure 2The pipe rack 1 of this metal pipe automatic cutting device is used to support the pipe to be cut, and then the pipe is moved to the cutting workbench 2. The tensioner 4 on the cutting workbench 3 can limit the position of the outermost end of the pipe. At the same time, the clamper 5 is pressed on the upper part of the pipe to complete the positioning of the pipe. Then the cutter 3 completes the cutting operation on the pipe.

[0023] See also Figure 3 The bottom plate 6 of the tensioner 4 is driven by the first cylinder 7 to move forward and backward on the cutting workbench 2. A push rod 9 is installed on the bottom plate 6 through a push rod seat 8. The top of the push rod 9 has an end plate, which can contact the end of the pipe. The tail end of the push rod 9 is fixedly connected to the screw 10. When the screw 10 rotates, it can be telescopically moved on the tail plate 11, thereby driving the push rod 9 to move forward and backward. The adjustment of the end position of the push rod 9 can realize the adjustment of the cut pipe length.

[0024] See also Figure 4 A second cylinder 12 is movably installed on the cross bar at the bottom of the cutting workbench 2, and the second cylinder 12 and the cutter 3 are also movably installed. When the second cylinder 12 is extended and retracted, the cutter 3 can be driven to swing based on the position installed on the cutting workbench 2 to perform cutting operations.

[0025] See also Figure 5 The pressing wheel 17 of the pressing device 5 is fixed on the sliding plate 14 through the second cylinder 16. The sliding plate 14 can move up and down on the guide column 13 under the operation of the lifting screw 15. The two lifting screws 14 realize synchronous rotation through the transmission method of the sprocket and the chain, thereby completing the purpose of the synchronous lifting operation of the sliding plate 14. Through the dual movement of the lifting plate 14 and the second cylinder 16, the maximum downward movement distance of the pressing wheel 17 is increased to meet the needs of the pipe pressing operation.

[0026] See also Figure 6 and Figure 7 The bracket 18 on the pipe rack 1 can be raised and lowered in the sleeve 20. The lifting operation is completed by the gear 22 on the transmission rod 21 and the rack on the support rod 18. The transmission rod 21 can drive the bracket 18 to move upward when it rotates. The bracket 18 is in a "Y" shape, which improves the stability of the pipe support. At the same time, the rods extending upward on both sides of the bracket 18 are covered with rolling tubes 19 to facilitate the sliding of the pipe.

[0027] See also Figure 8In order to facilitate the transfer of pipes, a pipe clamp mounting plate 23 is provided at the rear end of the pipe rack 1. A moving seat 24 is installed on the pipe clamp mounting plate 23 by means of a slide rail slider. The driving motor 27 drives the driving screw 28 to rotate, driving the moving seat 24 to move forward and backward. The two-way cylinder 25 drives the clamping head 26 to move inward and outward on the moving seat 24 to complete the clamping and loosening operation of the pipe. When delivering the pipe, the moving seat 24 moves to the front end of the pipe clamp mounting plate 23, and then the clamping head 26 clamps the pipe. The driving motor 27 is started to drive the moving seat 24 to move forward, and the pipe belt is conveyed forward. This cycle completes the operation of cyclic pipe delivery.
