Description

Technical Field

[0001] The present invention relates to the field of laser cutting technology, in particular to a large-format laser bevel cutting device and a use method thereof. Background Art

[0002] Laser cutting technology is a processing technology that is different from traditional cutting processes. It has the advantages of neat incisions and high work efficiency. Laser bevel cutting is a new technology. Based on laser cutting, it requires that in a complete workpiece cutting, the cutting height, knife gap compensation, knife edge compensation, feed speed, and corner transition must be adjusted synchronously and in real time with the change of the bevel angle to achieve the correct cutting size, bevel angle, and satisfactory surface quality.

[0003] According to a pipeline full-position laser beveling machine mentioned in Chinese invention 201511028565.1, the pipeline full-position laser beveling machine can solve the low efficiency of cold milling overhead beveling in the existing technology when used, and cannot meet the requirements of pipeline production lines for high-speed processing of pipeline beveling. However, the pipeline full-position laser beveling machine does not have the purpose of clamping the pipeline. After the beveling is completed, it is necessary to further manually remove the cut pipeline, which increases the labor force of the staff. Therefore, it is necessary to propose a large-scale laser beveling cutting equipment and a method of use to solve the above-mentioned problems. Summary of the Invention

[0008] Furthermore, a pipe body passes through the interior of the gear ring cylinder, and both ends of the pipe body are installed inside the fixing mechanism.

[0009] Furthermore, the first movable pulley is slidably mounted on the inner wall of the fixed cylinder, the second movable pulley is slidably mounted on the outer surface of the pipe body, and a groove cutting device is mounted on the outer surface of the gear ring cylinder.

[0011] Furthermore, a camera is fixedly installed on the bottom of the laser cutting machine, a control panel is fixedly installed on the front of the stabilizing frame, and an electrical box is fixedly installed on the top of the stabilizing frame.

[0012] Furthermore, the camera and the control panel are connected, and three movable guide rails are provided on the top of the fixed bottom box.

[0018] Step 4: After the final cutting is completed, the second stabilizing plate drives the cut pipe to move and separate.

[0019] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0020] 1. The large-format laser bevel cutting equipment and its use method are provided with a fixing mechanism. When in use, one end of the pipe is first fixed on the first stabilizing plate and the pipe body passes through the interior of the stabilizing frame, the fixing cylinder and the gear ring cylinder, and is fixed by the fixing mechanism. The control panel starts the micro drive motor, and the output shaft of the micro drive motor will drive the connecting rod and the first gear to rotate.

[0021] 2. The large-format laser bevel cutting equipment and its use method are as follows: by setting up the bevel cutting equipment, when in use, the hydraulic push rod and the laser cutting machine cooperate to push the laser cutting head to the outer surface of the pipe body, and the laser cutting head performs cutting. The cut end will be further clamped and fixed by a fixing mechanism to avoid the pipe body from being overheated after cutting and affecting the processing effect. After the cutting of one end of the pipe body is completed, the motor box, the threaded rotating rod and the threaded moving block will jointly push the second stabilizing plate to gradually approach the cut end of the pipe body to further clamp the one end of the pipe body, which can reduce the collision caused by the pipe body falling after cutting, thereby improving the efficiency of the bevel cutting of the pipe body.

[0022] 3. The large-format laser bevel cutting equipment and its use method are provided with a rotating mechanism. When in use, by starting the drive motor, the output shaft of the drive motor will drive the gear and the ring gear cylinder to engage with each other, driving the ring gear cylinder to rotate inside the fixed cylinder. The fixed rod and the first movable pulley are used to maintain the balance of the rotation of the ring gear cylinder, and the hydraulic lifting rod and the second movable pulley are used to rotate on the outer surface of the pipe body. At the same time, when the ring gear cylinder rotates, it will drive the bevel cutting equipment to rotate on the outer diameter of the pipe body to perform laser bevel cutting, thereby improving the cutting efficiency of the pipe body.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-5 In this embodiment, a large-format laser bevel cutting device includes a fixed bottom box 1, a first stabilizing plate 2 and a stabilizing frame 4 are fixedly installed on the top of the fixed bottom box 1, a second stabilizing plate 3 is movably installed on the top of the fixed bottom box 1, a fixing mechanism 12 is movably installed on one side of the first stabilizing plate 2 and the second stabilizing plate 3 corresponding to each other, a rotating mechanism 15 is movably installed inside the stabilizing frame 4, and a bevel cutting device 16 is installed inside the stabilizing frame 4;

[0031] The fixing mechanism 12 includes a micro-drive motor 121, and the micro-drive motor 121 is fixedly installed inside the first stabilizing plate 2 and the second stabilizing plate 3. The output shaft of the micro-drive motor 121 is fixedly connected to a connecting rod 122, and the outer surface of the connecting rod 122 is fixedly installed with a first gear 123. The outer surfaces of the first gear 123 are meshed with a second gear 124, and the interior of the second gear 124 is fixedly connected to an internal threaded fixing cylinder 125, and threaded push rods 126 are threadedly connected at both ends of the internal threaded fixing cylinder 125. Both ends of the two threaded push rods 126 are fixedly connected to a clamping plate 127, a limiting protrusion 128 is provided at the bottom of the clamping plate 127, and a fixing block 129 is fixedly installed on the right side of the clamping plate 127.

[0032] During specific implementation, by setting a fixing mechanism 12, when in use, one end of the pipe is first fixed on the first stabilizing plate 2 and the pipe body 13 passes through the interior of the stabilizing frame 4, the fixing cylinder 14 and the ring gear cylinder 153, and is fixed by the fixing mechanism 12. The control panel 6 starts the micro-drive motor 121, and the output shaft of the micro-drive motor 121 will drive the connecting rod 122 and the first gear 123 to rotate. The first gear 123 will engage with the second gear 124 to drive the second gear 124 and the internal threaded fixing cylinder 125 to rotate. At the same time, due to the limiting effect of the clamping plate 127 and the limiting protrusion 128, the threaded push rod 126 will be shortened to the middle part inside the internal threaded fixing cylinder 125, so that the clamping plate 127 and the fixing block 129 are gradually close to the outer surface of the pipe body 13, and finally the pipe body 13 is quickly clamped and fixed.

[0033] By setting up the bevel cutting equipment 16, when in use, the hydraulic push rod 162 and the laser cutting machine 163 will cooperate to push the laser cutting head 164 to move to the outer surface of the pipe body 13, and the cutting will be performed by the laser cutting head 164. The end where the cutting is completed will be further clamped and fixed by the fixing mechanism 12 to avoid the pipe body 13 from being overheated after the cutting is completed, which will affect the processing effect. After the cutting of one end of the pipe body 13 is completed, the motor box 8, the threaded rotating rod 9 and the threaded moving block 10 will jointly push the second stabilizing plate 3 to gradually approach the end where the cutting is completed of the pipe body 13 to further clamp one end of the pipe body 13, which can reduce the collision caused by the falling of the pipe body 13 after the cutting is completed, thereby improving the bevel cutting efficiency of the pipe body 13.

[0034] By setting up a rotating mechanism 15, when in use, by starting the driving motor 151, the output shaft of the driving motor 151 will drive the gear 152 and the ring gear cylinder 153 to engage with each other, driving the ring gear cylinder 153 to rotate inside the fixed cylinder 14, and the ring gear cylinder 153 is driven to maintain the balance of rotation through the fixed rod 154 and the first movable pulley 155, and rotates on the outer surface of the pipe body 13 through the hydraulic lifting rod 156 and the second movable pulley 157. At the same time, when the ring gear cylinder 153 rotates, it will drive the bevel cutting equipment 16 to rotate on the outer diameter of the pipe body 13 to perform laser bevel cutting, thereby improving the cutting efficiency of the pipe body 13.

[0035] By providing the fixing mechanism 12 and the rotating mechanism 15 , the pipe bodies 13 of different diameters can be clamped and laser groove cut simultaneously, and the plurality of pipe bodies 13 of different diameters can be adapted to improve the efficiency of laser cutting.
