[0033] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0034] Example 1:

[0035] Refer to the attached diagram in the instruction manual. Figure 1-4 This utility model provides an automatic pipe cutting machine, including a pipe cutting mechanism 100. The pipe cutting mechanism 100 includes a bracket 110 with a cutting blade assembly 111 at the end. A feeding assembly 112 for automatic pipe feeding is provided on the outer side of the bracket 110 station. A pipe placement rod 114 connected to the bracket 110 station is provided on the inner side of the bracket 110 station for pipe insertion. An electrically controlled moving seat 113 is provided on the bracket 110 for horizontal and reciprocating movement along a stabilizing rod 115. The moving seat 113 is powered by a cylinder, an electric slide rail, or an electric sleeve in conjunction with a lead screw. At least one pipe cutting station is provided on the bracket 110, and the number of cutting blade assembly 111 and feeding assembly 112 is adapted to the number of stations. A stabilizing rod 115 is connected to the bracket 110 at the bottom of the pipe placement rod 114, and there is at least one stabilizing rod 115 for supporting the bottom end of the pipe.

[0036] It also includes a tube clamping assembly 200, which includes a ring seat 210 connected to the movable seat 113. The ring seat 210 is provided with a rotating sleeve powered by a servo motor and belt, which is penetrated by a stabilizing rod 115. The rotating sleeve is formed by the threaded engagement of an outer cylinder 211 and an inner cylinder 212. The end of the inner cylinder 212 is in the shape of an inwardly tapered frustum. The outer side of the frustum is provided with protrusions 213 with beveled bottoms, which protrude from the through holes on the surface of the outer cylinder 211 and are used for internal support of the tube. A locking ring 214 is sleeved at the end of the tube rod 114. The inner cylinder 212 is embedded with an annular locking block 215, which is locked in the groove of the locking ring 214. The surface of the protrusion 213 is serrated. Both the surface of the protrusion 213 and the locking block 215 are provided with annular track grooves, and annular springs are placed in the grooves.

[0037] It also includes a waste discharge mechanism 300, which is placed on a ring seat 210.

[0038] In use, the feeding assembly 112 fits the end of the tube onto the tube placement rod 114. Then, the moving seat 113 drives the clamping assembly 200 to move closer to the tube until the outer cylinder 211 extends into the tube. At this time, the locking ring 214 is located inside the inner cylinder 212, and the locking block 215 is inserted into the groove of the locking ring 214, so that the inner cylinder 212 will not rotate with the outer cylinder 211. At the same time, the motor on the moving seat 113 starts and drives the outer cylinder 211 to rotate slightly on the surface of the tube placement rod 114 through the belt. With the thread engagement of the inner cylinder 212 and the outer cylinder 211, the inner cylinder 212 moves to the inside of the outer cylinder 211. At this time, the cone of the inner cylinder 212 gradually pushes out the protrusion 213 until it is tightly attached to the inner wall of the tube for external support and clamping. Then the moving seat 113 moves in the opposite direction, and the tube is completely pulled into the tube placement rod 114, completing the tube insertion work.

[0039] During pipe cutting, the moving seat 113 moves forward intermittently, driving the pipe body to extend continuously along the pipe rod 114. The motor on the moving seat 113, in conjunction with the belt, drives the outer cylinder 211 to rotate, thereby allowing the pipe body to rotate and be cut off on the descending cutter. This process is repeated to complete the pipe cutting work.

[0040] After the pipe is cut, the moving seat 113 will be positioned again near the end of the pipe inserting rod 114, and the locking block 215 will be inserted into the groove of the locking ring 214 again, rotating the inner cylinder 212. At this time, the motor supplying power to the outer cylinder 211 will reverse, allowing the inner cylinder 212 to retract from the outer cylinder 211 and the locking block 215 to retract, thus releasing the clamping of the remaining pipe.

[0041] Example 2:

[0042] Refer to the attached diagram in the instruction manual. Figure 5-6 The difference between this embodiment and the above embodiment is that: the waste discharge mechanism 300 includes a connecting frame 310 connected to the ring seat 210, and a push sleeve frame 311 is connected to one side of the connecting frame 310 by a cylinder. The push sleeve of the push sleeve frame 311 is placed outside the outer cylinder 211 for the waste pipe to be pushed out. The waste discharge mechanism 300 also includes a discharge hopper 312 placed at the discharge port of the support 110. The discharge hopper 312 is provided with a notch, and an electrically powered derailment plate 313 is provided at the notch.

[0043] When the clamping block 215 releases its grip on the remaining tube, the cylinder pushes the pusher frame 311 forward, causing the pusher to move along the outer cylinder 211 and push the remaining tube out of the outer cylinder 211 and the tube placement rod 114. At the same time, the diversion plate 313 on the discharge hopper 312 opens, allowing the cut remaining tube to fall into the notch of the discharge hopper 312. After the cylinder of the pusher frame 311 is reset, the above operation can be repeated on the tube placement rod 114 to continuously complete the tube insertion and cutting work.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
