Description

Automatic change laser pipe cutting machine

Technical Field

Background

When the pipe material is cut, the pipe material cannot be used as a qualified part after cutting and blanking due to the uneven appearance of the end face of the pipe material, so that a small part of the end face of the pipe material needs to be cut off, the cut end face is very neat and attractive, and the step is called as a flat end face of the pipe material. The pipe material with the flat end face can be normally cut according to a certain size. When the pipe material is cut to a certain short length, the pipe material is not enough to cut a part with a standard material length, and the material tail cannot be used and should be removed. Most of the existing laser pipe cutting machines are of a semi-automatic structure, most of the flat end faces and the tailing removing process are manually and visually observed, and the existing laser pipe cutting machines are discarded after cutting the tailing. The operation process is complicated and the efficiency is low;

in addition, when laser cutting is carried out, according to the length of a cut pipe material, a stop block needs to be additionally arranged at the tail of the laser pipe cutting machine, the stop block plays a role of sizing, the distance between the stop block and the laser head determines the length of the cut pipe, the shorter the stop block is, and the longer the stop block is, the shorter the stop block is, and the longer the stop block is. The stop gear on the laser pipe cutting machine in the existing market is mostly manually adjusted, needs manual alignment, and the zero point of the visual inspection dog corresponds to the ideal scale of the scale, and the dog is slid to the desired distance through the sliding guide rail, and then is locked and fixed by the locking wrench. Not only is time wasted, but also certain deviation exists in the positioning position due to manual visual inspection.

There is therefore a need for an automated laser pipe cutter that addresses the above-mentioned problems.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description.

The utility model provides an automatic change laser pipe cutting machine, as shown in fig. 1 and 2, including pipe material unloading equipment, pipe material conveying mechanism 13, air chuck 10 and the laser cutting head 3 that set gradually, the below of laser cutting head 3 is equipped with photoelectric sensor 11 with the position department that treats that the pipe material corresponds, pipe material conveying mechanism is in treat that the route below of pipe material is equipped with proximity sensor 12.

As shown in fig. 3, a laser pipe cutting quick sizing mechanism is further arranged on the cutting workbench below the cutting head of the laser pipe cutting machine 1, and comprises a sizing stop block 5 and a ball screw assembly, wherein the sizing stop block 5 is fixedly mounted on a transmission nut of the ball screw assembly. The ball screw assembly comprises a workbench, a sliding guide rail 7 and a ball screw nut pair 6 are respectively arranged on the workbench through a fixed mounting seat, a transmission nut is movably connected with the sliding guide rail 7 and the ball screw nut pair 6 through a mounting seat, and the ball screw nut pair 6 is connected with a servo motor 8 through a bearing assembly and a belt transmission mechanism 9.

The control assembly of the servo motor 8 is arranged in the controller of the laser cutting machine, and the control assemblies of the photoelectric sensor 11 and the proximity sensor 12 are also arranged in the controller of the laser cutting machine, so that when the laser cutting head 3 cuts a pipe material to be cut 4, the fixed-length stop block 5, the photoelectric sensor 11 and the proximity sensor 12 can be controlled by the touch screen 2 arranged in the laser cutting machine to perform accurate cutting.

Besides, in order to realize full process automation, the pipe blanking equipment and the pipe conveying mechanism are also set as automation equipment.

When the laser cutting head is used, the size and thickness of the flat end surface of the laser depend on the photoelectric sensor at the rear end of the laser cutting head, and the horizontal distance between the photoelectric sensor and the laser head determines the size and thickness of the flat end surface. When the tube material is conveyed to the infrared position of the photoelectric switch from the air chuck. The control system feeds back signals to the pneumatic chuck, and the pneumatic chuck locks and drives the pipe material to rotate for a circle (simultaneously, the laser head cuts). After cutting, the stub bar falls freely, and the end face flattening is completed;

After the pipe material is cut by the laser for a period of time, when the rear end face of the tailing is about to leave the roller of the pipe material conveying mechanism 13 and just separate from the proximity sensor for detecting the pipe material, the control system starts to calculate the excess material cutting quantity and the tailing length. The cutting excess material quantity is equal to the size of the sensor and the laser cutting head divided by the standard fixed length of the cut part. The tailing length is the remainder after calculation by the formula. Therefore, the cutting is not continued after the last qualified part is cut, and the next pipe material to be cut is conveyed to the rear end of the tailing material to eject the tailing material. And then continuously and circularly cutting and blanking the flat end surface of the pipe to be cut.
