A combined pipe cutting machine

Abstract

The invention discloses a combined pipe cutting machine. The combined pipe cutting machine comprises a laser pipe cutting machine, a saw web pipe cutting device and a pipe material collection hopper,and the saw web pipe cutting device comprises a frame, a pipe material conveying device and a saw web cutting machine; and one end of the frame is jointed with one end of a lathe bed, the pipe material conveying device is arranged on the frame in a sliding form, the saw web cutting machine is fixedly arranged on the frame, the pipe material conveying device can be respectively in abutting joint with the laser pipe cutting machine and the saw web cutting machine, and the pipe material collection hopper is arranged under the frame. The combined pipe cutting machine has the following beneficial effects: when a last section of a pipe material cannot be cut by the laser pipe cutting machine, the last section of the pipe material is conveyed by the pipe material conveying device to be located under the saw web cutting machine, the saw web cutting machine completes cutting, thus, no-tailing production is realized, pipe material loss is reduced, production cost is reduced, and moreover, the combined pipe cutting machine is compact in structure, efficient in automatic feeding, simple in action, efficient in cutting, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of pipe cutting equipment, in particular to a combined pipe cutting machine. Background technique [0002] Laser cutting has the advantages of smooth cutting surface, high cutting efficiency and high cutting precision, so laser cutting has been widely used, and laser pipe cutting machine is one of the applications of laser cutting; [0003] Traditional laser pipe cutting equipment usually only includes a fixed chuck and a movable chuck. For example, CN105458522A discloses a pipe cutting machine, which includes a frame, a fixed chuck arranged at one end of the frame, and a fixed chuck arranged at the other end of the frame. The feeding chuck at one end, the fixed chuck driving device and the feeding chuck driving device for driving the fixed chuck and the feeding chuck to rotate respectively, the transfer device for driving the feeding chuck to move and feed, and the pipe cutting device for cutting the pipe ...

Problems solved by technology

[0003] Traditional laser pipe cutting equipment usually only includes a fixed chuck and a movable chuck. For example, CN105458522A discloses a pipe cutting machine, which includes a frame, a fixed chuck arranged at one end of the frame, and a fixed chuck arranged at the other end of the frame. The feeding chuck at one end, the fixed chuck driving device and the feeding chuck driving device for driving the fixed chuck and the feeding chuck to rotate respectively, the transfer device for driving the feeding chuck to move and feed, and the pipe cutting device for cutting the pipe device, in actual use, the fixed chuck and the feeding chuck clamp the pipe fittings, the pipe cutting device cuts the pipe, after the pipe cutting is completed, the fixed chuck releases the pipe fittings, and the moving device drives the feeding chuck to clamp the pipe fittings. The feeding and pipe cutting device reprocesses the pipe fittings. The advantages of the double chuck laser pipe cutting machine are compact structure, efficient automatic feeding, simple action, safety and reliability, and high cutting efficiency. However, due to the structural limitations of traditional laser pipe cutting equipment, When the double-chuck laser pipe cutting machine is laser cutting, the last section of each pipe is always out of the cutting range, that is, when the feeding chuck moves to the fixed chuck to the limit position, the last section of the pipe is located in the fixed chuck. The end face cannot be cut, and this section of pipe is usually called the tail material, which causes the problem of material waste and increases the production cost

[0004] The current improvement method on the market is to design a multi-chuck laser pipe cutting machine, such as CN110421277A discloses a three-chuck laser pipe cutting machine, including a base, a first chuck, a second chuck, and a third chuck and the laser head, the first chuck, the second chuck and the third chuck can all be slidably arranged on the base, the first chuck and the second chuck are arranged at both ends of the base, the first chuck The three chucks are arranged between the ground chuck and the second chuck, the laser head is arranged on the base, the laser head can move along the width direction and the height direction of the base, and the An auxiliary support mechanism that moves up and down in the height direction of the base; another example is CN109848585A which discloses a laser pipe cutting machine, including a base, a first chuck, a second chuck, a third chuck, a fourth chuck and a laser head, The first chuck, the second chuck, the third chuck and the fourth chuck can all be slidably arranged on the base, and the first chuck and the second chuck are arranged at both ends of the base, and the The third chuck is arranged between the first chuck and the second chuck, the fourth chuck is arranged between the first chuck and the third chuck, the laser head is arranged on the upper end of the base, and The laser head can move along the length direction of the base; the advantages of the above two kinds of multi-chuck laser pipe cutting machines are that they can realize real zero-tail cutting, reduce raw material consumption, environmental protection and energy saving, and reduce production costs; but the multi-chuck laser Because the laser head needs to move between the chucks of the cutting machine, the action is cumbersome, and the cutting efficiency is more than 80% slower than that of the double chuck laser pipe cutting machine. The loss of tailings is reduced by sacrificing time, and the efficiency of automatic feeding is low.
