[0051] See also Figure 1 and Figure 2 The cutting mechanism provided in the embodiment of the present application is now described. The cutting mechanism provided in the embodiment of the present application comprises a pipe cutting device 1, and the pipe cutting device 1 comprises:

[0052] Pipe cutting main bed 11;

[0053] A front chuck 12 is installed on the pipe cutting main bed 11 and is used to clamp the pipe fittings;

[0054] A rear chuck 13 is movably mounted on the pipe cutting main bed 11 and is used to clamp the pipe;

[0055] The support assembly 14 includes a lifting drive member 141, a height adjustment member 142 and a support member 143. The lifting drive member 141 is installed on the pipe cutting main bed 11. The height adjustment member 142 is in transmission connection with the lifting drive member 141. The support member 143 is detachably installed on the height adjustment member 142. The support member 143 is used to support the pipe fitting.

[0056] When the front chuck 12 and the rear chuck 13 clamp the pipe, the lifting drive member 141 lifts the support member 143 to support the pipe.

[0057] The support assembly 14 in the embodiment of the present application is fixed on the pipe cutting main bed 11. Since the rear chuck 13 needs to move along the length direction of the pipe cutting main bed 11, the support assembly 14 needs to drive the support member 143 through the lifting drive member 141 to avoid the rear chuck 13. When the rear chuck 13 moves, the specific position of the rear chuck 13 is fed back by the servo motor driving the rear chuck 13. After the lifting drive member 141 receives the retraction signal, the lifting drive member 141 drives the support member 143 to retract, so that the height of the support member 143 is lower than the horizontal plane where the rear chuck 13 moves. The rear chuck 13 can move along the length direction of the pipe cutting main bed 11 to ensure that the cutting work proceeds smoothly. When the rear chuck 13 passes, the lifting drive member 141 drives the support member 143 to rise, so that the support member 143 supports the pipe fittings to prevent the pipe fittings from sagging and swinging during cutting. When the support member 143 rises, the rear chuck 13 cannot move over the support member 143.

[0058] The lifting drive member 141 can be a motor, a cylinder or an electric cylinder, preferably a cylinder. The driving shaft of the cylinder is connected to the height adjustment member 142, and the cylinder drives the height adjustment member 142 to rise and fall, thereby driving the support member 143 on the height adjustment member 142 to rise and fall.

[0059] See also Figure 4The height adjustment member 142 includes a mounting portion 1421, an adjustment portion 1422 and an adjustment rod 1423. The mounting portion 1421 is transmission-connected to the lifting drive member 141. A height adjustment slot 1424 is provided on the mounting portion 1421. The adjustment portion 1422 is slidably disposed in the height adjustment slot 1424. The support member 143 is detachably mounted on the adjustment portion 1422. The adjustment rod 1423 is inserted into the mounting portion 1421 and the adjustment portion 1422 to fix the adjustment portion 1422.

[0060] The adjusting portion 1422 in the embodiment of the present application is a plate-shaped slider slidably disposed in the height adjustment slot 1424 of the mounting portion 1421. The adjusting rod 1423 is a screw rod, one end of which is inserted from the bottom of the height adjustment slot 1424 and threadedly connected to the adjusting portion 1422. When the adjusting rod 1423 is rotated, the adjusting portion 1422 can be driven to slide along the length direction of the height adjustment slot 1424. The support member 143 is mounted on the adjusting portion 1422 by bolts. By rotating the adjusting rod 1423, the height of the support member 143 located on the adjusting portion 1422 can be adjusted.

[0061] When the pipe supported by the support member 143 is a circular pipe, the following method is used: Figure 2 In the structure shown, the support member 143 includes a first rolling roller 1431 and a mounting seat 1432, the first rolling roller 1431 is rotatably mounted on the mounting seat 1432, the mounting seat 1432 is detachably mounted on the height adjustment member, and the first rolling roller 1431 is used to support the circular tube.

[0062] The first rolling roller 1431 in the embodiment of the present application is installed on the mounting seat 1432 through a rotating shaft. The first rolling roller 1431 can reduce the friction between the support member 143 and the pipe member.

[0063] When the pipe supported by the support member 143 is a rectangular pipe, the following method is used: Figure 3 In the structure shown, the support member 143 includes a first support portion 1433 and a second support portion 1434. The first support portion 1433 and the second support portion 1434 form a V-shaped groove and are installed on the height adjustment member. The V-shaped groove is used to support the rectangular tube.

[0064] If the support member 143 and the rectangular tube are in surface contact, the width and length of the cross section of the rectangular tube are inconsistent, and when the rectangular tube rotates, the support member 143 may not be able to avoid it, resulting in damage to the rectangular tube or the support member 143. Therefore, by providing a V-shaped groove, the rectangular tube can be avoided and supported at the same time.

[0065] The first support part 1433 and the second support part 1434 are both provided with a second rolling roller 1435 for supporting the rectangular tube. The second rolling roller 1435 can reduce the friction between the support part 143 and the tube.

[0066] The angle formed by the first support portion 1433 and the second support portion 1434 is 85°-95°. Preferably, the angle formed by the first support portion 1433 and the second support portion 1434 is 90°.

[0067] When the supported rectangular tube is rotated 90°, it can always contact with the V-shaped groove to achieve the purpose of support. At other angles greater than 95°, such as 100° or 120°, the rectangular tube is suspended in the V-shaped groove after rotating 90°, and the support member 143 cannot achieve the purpose of support. Conversely, other angles less than 85°, such as 60° or 70°, may interfere with the rotation of the rectangular tube.

[0068] The pipe cutting main bed 11 includes a mounting frame 111 and a guide member 112. The guide member 112 is arranged on the mounting frame 111 along the length direction of the pipe cutting main bed 11. The front chuck 12 is installed on the mounting frame 111. The rear chuck 13 is connected to the guide member 112. The support assembly 14 is installed on the mounting frame 111 and is arranged below the guide member 112 to avoid the rear chuck 13.

[0069] The guide member 112 in the embodiment of the present application includes a guide rail and a slider, the slider is slidably connected to the guide rail, the rear chuck 13 is connected to the slider, the guide rail is arranged along the length direction of the pipe cutting main bed 11, and the rear chuck 13 moves along the length direction of the guide rail. The support assembly 14 is installed on the square tube of the mounting frame 111 so that the support assembly 14 is not damaged during unloading. At the same time, the height of the support assembly 14 in the retracted state is lower than the guide member 112 to avoid the rear chuck 13, and the height of the support assembly 14 in the extended state is higher than the guide member 112 to support the pipe fitting.

[0070] The support assembly 14 is installed obliquely on the mounting frame 111 to prevent the support assembly 14 from being too high to block the movement of the rear chuck 13 .

[0071] The pipe cutting main bed 11 in the embodiment of the present application has a relatively short bed body, and the vertical arrangement of the support assembly 14 on the mounting frame 111 will cause the height of the support assembly 14 to be too high, making it difficult to avoid the rear chuck 13 .

[0072] See also Figure 5 The cutting mechanism further comprises a cutting device 2, wherein the cutting device 2 comprises:

[0073] The plate cutting main bed 21 is arranged on one side of the pipe cutting main bed 11;

[0074] A crossbeam 22 is movably disposed on the cutting board main bed 21;

[0075] A lifting assembly 23 is movably mounted on the crossbeam 22;

[0076] The cutting assembly is connected to the lifting assembly 23 and is used for cutting the plate.

[0077] One end of the crossbeam 22 extends to the pipe cutting main bed 11 , so that the cutting assembly can be moved to the pipe cutting main bed 11 along with the lifting assembly 23 to cut pipes.

[0078] The cutting assembly in the embodiment of the present application is a laser cutting device, and the lifting assembly 23 can be a lifting and moving platform driven by a motor, a cylinder or an electric cylinder.

[0079] The embodiment of the present application can perform laser cutting operations on plates and various pipes. When plate cutting is required, the plate is placed on the plate cutting main bed 21; when round tubes or rectangular tubes are required to be cut, the tubes are clamped by the front chuck 12 and the rear chuck 13, and the tubes pass through the middle of the through holes of the front chuck 12 and the rear chuck 13 and are automatically clamped. The support assembly 14 is adjusted so that the support member 143 of the support assembly 14 is in contact with the tube to provide support for the middle part of the tube to prevent the middle part of the tube from falling, and the automatic feeding of the tube is realized by the rear chuck 13 assembly.

[0080] When in use, the plate cutting machine and the pipe cutting machine share a crossbeam 22 and a lifting assembly 23. The cutting assembly can realize vertical, horizontal and longitudinal movement to cut plates and various pipes. It can cut a variety of workpieces with high cutting accuracy, high efficiency and low cost.

[0081] A waste collecting member 15 is disposed on a side of the front chuck 12 away from the rear chuck 13 , and the waste collecting member 15 is used to collect cutting waste.

[0082] The waste collection member 15 in the embodiment of the present application is a box-type trolley, which is convenient for workers to push and can keep the production space clean and tidy.

[0083] The above description is only a preferred embodiment of the present application and is not intended to limit the present application.
