Online cutting-off device and online automatic tube cutting method

Abstract

The invention discloses an online cutting-off device and an online automatic tube cutting method. The online cutting-off device comprises a rack, a clamping device used for clamping a tube, a cutting-off device used for cutting off the tube, a driving device used for driving the clamping device to move and a chain connected between the cutting-off device and the clamping device, wherein the clamping device is located at the initial position and tightly attached to the cutting-off device. A tube sequentially penetrates through the cutting-off device and the clamping device from the tube inlet end of the rack and then continuously moves towards the tube outlet end of the rack; the driving device drives the clamping device to move in the moving direction of the tube, the clamping device clamps the tube and drives the cutting device to move synchronously through the chain, the cutting device cuts off the tube in the synchronous moving process, and the clamping device loosens the tube and drives the cutting device to return to the initial position under the action of the driving device. The cutting-off precision is high, and on-line continuous cutting-off can be achieved.

Description

Technical field [0001] Technical Field The present invention relates to cutting devices and more particularly relates to an online cutting device, automatically cut the pipe-line method. Background technique [0002] In the process pipe, the pipe needs to be generally sized cut off the existing pipe in the pipe cutting line, it is difficult to obtain a highly accurate length of the pipe means. Specifically, when the length of the pipe reaches a preset value, the cutting apparatus receives a signal to start cutting off, since the received signal to the embodiment of this process the cutting operation takes time, and the pipe is moved up, so that there will be some cutting apparatus delay, the actual length of the pipe will be longer than the preset number. Inventive content [0003] The present invention solves the technical problem is to provide an on-line cutting apparatus, high precision cutting can be achieved off-line stop. [0004] The present invention is also the technica...

Problems solved by technology

[0002] In the pipe making process, it is generally necessary to cut the pipe to a fixed size. The existing pipe cutting device is difficult to obtain high-precision pipe length in the online cutting of the pipe.

Specifically, when the length of the pipe reaches the preset value, the cutting device receives the cutting signal to start cutting. Since the process from receiving the signal to implementing the cutting action also takes time, and the pipe is always moving, the cutting device will appear certain Delay, the actual length of the pipe will be longer than the preset value
