In the description of the present application, "a plurality of" means two or more, unless otherwise specifically defined.

[0034] Please refer to Figure 1 , and a laser pipe cutting machine provided by an embodiment of the present application will be described below. The laser pipe cutting machine provided by the embodiment of the present application includes:

[0035] A main machine bed 1;

[0036] A plurality of clamping devices 2, which are arranged on the main machine bed 1 at intervals along the length direction of the main machine bed 1 and are used for clamping workpieces;

[0037] A laser cutting device 3, which is used for cutting the workpieces clamped by the clamping devices 2;

[0038] A tail material collection assembly 4, which is used for collecting the tail materials after cutting, including a first inclined surface 41 and a tail material collection box 42. The first inclined surface 41 is arranged on the main machine bed 1, the tail material collection box 42 is arranged on one side of the main machine bed 1, the first inclined surface 41 is inclined towards the tail material collection box 42, and a first buffer pad is laid on the first inclined surface 41.

[0039] In the embodiment of the present application, the clamping device 2 can be a jaw, a manipulator, a chuck, etc. The clamping device 2 is at least provided with two. One clamps the tail end of the workpiece, and the other clamps the cutting end of the workpiece. The laser cutting device 3 is arranged at one end of the main machine bed 1 and is close to the clamping device 2 that clamps the cutting end of the workpiece. And the first inclined surface 41 is close to the clamping device 2 that clamps the tail end of the workpiece. Wheels or other moving parts can be arranged at the bottom of the tail material collection box 42 for easy pushing.

[0040] After the laser cutting device 3 finishes cutting the workpiece, the clamping device 2 that clamps the tail end of the workpiece releases the tail stock. The tail stock falls from the clamping device 2 onto the first inclined surface 41 and then flows from the first inclined surface 41 into the tail stock collection box 42. In this way, there is no need for manual collection of the tail stock, saving labor costs. At the same time, the first inclined surface 41 can prevent the tail stock from falling straight into the tail stock collection box 42, reducing damage to the tail stock. A first buffer pad is also laid on the first inclined surface 41. The first buffer pad can reduce the damage rate of the tail stock caused by the collision when the tail stock falls onto the first inclined surface 41, improving the utilization rate of the recycled tail stock. At the same time, the first buffer pad can also reduce the noise generated by the collision and friction between the tail stock and the first inclined surface 41.

[0041] The first buffer pad can be a silicone pad with elasticity or a soft pad made of other materials.

[0042] The laser tube cutting machine further includes a finished product collection assembly 5. The finished product collection assembly 5 includes a blanking table 51 and a finished product collection box 52. The blanking table 51 is connected to the laser cutting device 3. The blanking table 51 is used to guide the finished product after cutting to the finished product collection box 52. The finished product collection box 52 is arranged on one side of the blanking table 51 to collect the finished product after cutting.

[0043] In the embodiment of the present application, the finished product after cutting by the laser cutting device 3 in the laser cutting device 3 can directly fall onto the blanking table 51 and flow from the blanking table 51 to the finished product collection box 52. Wheels or other moving parts can be provided at the bottom of the finished product collection box 52 for easy pushing.

[0044] The blanking table 51 includes a second inclined surface 511 and a third inclined surface 512. The second inclined surface 511 is inclined towards the third inclined surface 512. The laser cutting device 3 is connected to the second inclined surface 511. The second inclined surface 511 is used to guide the finished product after cutting by the laser cutting device 3 to the third inclined surface 512. The third inclined surface 512 is inclined towards the finished product collection box 52. The third inclined surface 512 is used to guide the finished product after cutting to the finished product collection box 52. A second buffer pad is laid on the third inclined surface 512.

[0045] In the embodiment of the present application, since the blanking table 51 has a certain height, setting two inclined surfaces can reduce the floor area of the blanking table 51. At the same time, it can prevent the inclined surface from being too steep, resulting in too high a moving speed of the workpiece. If the moving speed of the workpiece is too high, it will collide with the wall surface of the finished product collection box 52, which may cause damage to the workpiece. A third buffer pad can also be laid on the second inclined surface 511. The second buffer pad and the third buffer pad can be a silicone pad with elasticity or a soft pad made of other materials.

[0046] The lifting support assemblies 11 are arranged at intervals along the length direction of the main machine tool 1, and the lifting support assemblies 11 are arranged between two adjacent clamping devices 2 to support the workpiece.

[0047] In the embodiment of the present application, the lifting support assembly 11 can be a support member driven by a driving device such as a motor, a cylinder or an electric cylinder. The support member can be a platform provided with a limiting groove, or an arc-shaped claw, and the workpiece is arranged in the limiting groove or the arc-shaped claw. Taking the cylinder as an example, the cylinder is installed on the main machine tool 1, the support member is connected to the output end of the cylinder, and the cylinder drives the support member to lift to support the workpiece.

[0048] Preferably, the lifting support assembly 11 includes a variable-diameter wheel 111, a mounting member 112 and a first lifting driving member. The variable-diameter wheel 111 is rotatably mounted on the mounting member 112, the mounting member 112 is in transmission connection with the first lifting driving member, and the variable-diameter wheel 111 is used to support the workpiece.

[0049] In the embodiment of the present application, the circumferential surface of the variable-diameter wheel 111 is an arc-shaped surface, and the workpiece can be placed in the space formed by the circumferential surface at the top of the variable-diameter wheel 111. Moreover, along the circumferential direction of the variable-diameter wheel 111, the size of the circumferential surface of the variable-diameter wheel 111 gradually changes, so that during the rotation of the variable-diameter wheel 111, the size of the circumferential surface at the top of the variable-diameter wheel 111 gradually changes, for example, the depth and the radian continuously increase. Therefore, by rotating the variable-diameter wheel 111, the top of the variable-diameter wheel 111 can be lowered to support workpieces of different sizes. The variable-diameter wheel 111 can correspondingly support workpieces of different sizes and prevent the workpiece from being thrown out or sagging during the support process, which may affect the cutting accuracy.

[0050] The first lifting driving member can be a cylinder, an electric cylinder or a motor. Taking the cylinder as an example, the cylinder is installed on the main machine tool 1, the mounting member 112 is connected to the output end of the cylinder, and the cylinder drives the mounting member 112 and the variable-diameter wheel 111 to lift to support the workpiece.

[0052] When the length of the processed workpiece is too long, the lifting support assembly 11 can be added at the preparatory installation position. When the lifting support assembly 11 needs to be supplemented, the first lifting driving member raises the variable-diameter wheel 111 to expose the opening, so as to support the too-long workpiece; when the processed workpiece is of a conventional length, the first lifting driving member lowers the variable-diameter wheel 111 to a position below the opening, and then covers the opening with the cover plate 515. The cover plate 515 can prevent foreign objects from entering the blanking table 51 from the opening.
