Description

Technical Field

[0001] The invention belongs to the technical field of laser cutting machines, and in particular relates to a split type cutting machine and a cutting method. Background Art

[0002] The workbench and bed of the split cutting machine are set separately to reduce the heat transfer from the workbench to the bed, thereby improving the cutting accuracy. With the development of modern mechanical processing industry, the requirements for cutting quality and precision are constantly improving, and the requirements for improving production efficiency, reducing production costs, and having highly intelligent automatic cutting functions are also increasing. Split cutting machines are divided into flame cutting machines, plasma cutting machines, laser cutting machines, water cutting machines, etc. Among them, laser cutting machines have the fastest efficiency, the highest cutting accuracy, and generally smaller cutting thickness.

[0003] The laser cutting machines of the prior art have the following problems: First, in some existing laser cutting machines, the workpiece generally remains stationary when the cutting device is cutting the workpiece, so the processing efficiency is low; in order to improve the processing efficiency, some cutting machines design the workpiece and the cutting device to move synchronously, and cut while moving, but the movement of the workpiece and the movement of the cutting device are controlled separately and independently of each other, so there is a problem of asynchronous movement, resulting in fine wavy cuts and poor cutting accuracy; second, when the laser cutting machine cuts round tube materials, the laser cutting machine needs to cut the round tube in a ring. When the laser cutting machine has not completely cut the round tube, the round tube material at the cutting position will break due to its own gravity, resulting in large burrs on the cut surface of the material, affecting the quality of the material. At the same time, the broken round tube material can easily damage the laser cutting machine during the ring cutting process, causing damage to the laser cutting machine. Summary of the invention

[0015] A cutting method for a split cutting machine, the method is applied to the split cutting machine as described above, the method comprising the following steps:

[0016] Step S1: The round tube passes through the clamping disk and the cutting disk in sequence. After passing through the cutting disk, the round tube contacts the end of the pull rod. As the round tube moves, the round tube drives the pull rod to move synchronously, and the pull rod drives the clamping disk to move through the connector;

[0017] Step S2: During the sliding process of the clamping disk, the connecting rod inside the clamping disk rotates inwardly.

[0018] Step S3: Under the clamping of the clamping head, the round tube between the end of the pull rod and the clamping head is fixed. When the clamping head clamps the round tube, the round tube, the clamping connection assembly, the cutting assembly and the workbench form a whole.

[0019] As a further optimization or improvement of this solution, step S1 specifically includes the following steps:

[0020] Step S11: After passing through the cutting disc, the round tube contacts and presses the push block, and the push block drives the L-shaped rod to rotate through the push rod and the connecting block, and the L-shaped rod presses the outer side wall of the end of the round tube through the pressing block;

[0021] Step S12: The pressing block presses the side wall of the end of the circular tube to correct the inclination angle of the end of the circular tube, so that the distance between the laser and the circular tube is constant.

[0022] Beneficial effects of the present invention:

[0023] (1) During use, the round tube passes through the clamping disk and the cutting disk in sequence under the action of the feeding device, and then the round tube drives the pull rod to move synchronously, and the pull rod drives the clamping disk to move through the connecting head, and the movement of the clamping disk drives the clamping head on the connecting rod to press and clamp the outer wall of the round tube, so that the clamping connection assembly is connected to the round tube; under the clamping of the clamping head, the round tube between the end of the pull rod and the clamping head is fixed, and because the laser is located between the end of the pull rod and the clamping head, during the process of laser cutting the round tube, the laser can completely cut the round tube, avoiding the phenomenon that the round tube breaks due to its own gravity during the process of laser cutting the round tube, resulting in large burrs on the cut surface of the round tube, and at the same time avoiding the falling of the cut tube to damage the laser;

[0024] Specifically, when the clamping head clamps the round tube, the round tube, the clamping connection assembly, the cutting assembly and the workbench form a whole, so the round tube and the cutting assembly achieve synchronous movement, thereby improving the cutting accuracy of the laser.

[0025] (2) The laser is adjusted to a suitable position by means of vertical and horizontal slide rails, and the drive motor is started to drive the turntable to rotate. The turntable drives the round tube to rotate through the connecting rod, and the laser is used to cut the round tube in a circular manner. The present invention uses the self-rotation of the round tube to cooperate with the laser for circular cutting, thereby avoiding the problem of laser beam interference and simplifying the layout of the laser.

[0026] (3) The push block is pressed by the round tube, so that the push block drives the L-shaped rod to rotate through the push rod and the connecting block. The L-shaped rod presses the outer wall of the end of the round tube through the pressure block to correct the inclination of the end of the round tube, so that the distance between the laser and the round tube is constant, ensuring that the laser can cut the round tube evenly.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0042] See also Figure 1-Figure 10 A split cutting machine includes a frame shell 1 and a round tube 7, a bed frame 2 is installed inside the frame shell 1, a guide rod 3 is installed on the bed frame 2, the guide rod 3 is connected to the workbench 4 by transmission, a clamping connection component 8 and a cutting component 9 are respectively installed on the workbench 4, the clamping connection component 8 is slidably installed on the workbench 4, the cutting component 9 is fixedly installed on the workbench 4, a positioning correction component 5 is slidably installed on the clamping connection component 8 and the cutting component 9, and the round tube 7 is sequentially inserted into the clamping connection component 8 and the cutting component 9;

[0043] The cutting assembly 9 includes a cutting disc 901 and an adjustable laser 905 mounted on the cutting disc 901. The clamping connection assembly 8 includes a clamping disc 801 and a turntable 806 rotatably mounted inside the clamping disc 801. A vertical slot 816 is provided inside the turntable 806. A connecting rod 815 is rotatably mounted inside the vertical slot 816. A clamping head 814 is rotatably connected to the connecting rod 815. The clamping head 814 fits the outer wall of the circular tube 7. The turntable 806 is driven by a driving motor 804. A reset spring 11 is connected between the clamping disc 801 and the cutting disc 901.

[0044] The positioning and correction component 5 includes a pull rod 501 and a connecting head 502. The pull rod 501 is slidably connected to the clamping disk 801 and the cutting disk 901 respectively. The connecting head 502 is installed at one end of the pull rod 501, and the connecting head 502 is connected to the clamping disk 801. After the round tube 7 is inserted into the clamping connection component 8 and the cutting component 9, it is top-connected to the other end of the pull rod 501.

[0045] It should be noted that the round tube 7 is connected to the feeding device so that the round tube 7 enters the clamping connection component 8 and the cutting component 9 in sequence under the action of the feeding device; a driving device is installed at the bottom of the workbench 4. When the cutting component 9 completes cutting, the workbench 4 quickly transports the clamping connection component 8 and the cutting component 9 thereon to the initial position, so that the clamping connection component 8 and the cutting component 9 can operate continuously.

[0046] The round tube 7 passes through the clamping disk 801 and the cutting disk 901 in sequence under the action of the feeding equipment, and the clamping head 814 is attached to the outer wall of the round tube 7. After passing through the cutting disk 901, the round tube 7 contacts the end of the pull rod 501. As the round tube 7 moves, the round tube 7 drives the pull rod 501 to move synchronously. In this process, the pull rod 501 drives the clamping disk 801 to move through the connecting head 502, so that the clamping disk 801 slides along the slide groove 813 on the slide table 802. In the process of the sliding of the clamping disk 801, since the clamping head 814 is attached to the outer wall of the round tube 7, the connecting rod 815 inside the clamping disk 801 rotates inwards, as shown in FIG. Figure 6 As shown, as the connecting rod 815 rotates, the clamping head 814 on the connecting rod 815 presses and clamps the outer wall of the round tube 7, so that the clamping connection assembly 8 is connected to the round tube 7. Under the clamping of the clamping head 814, the round tube 7 between the end of the pull rod 501 and the clamping head 814 is fixed, see Fig. 9 Since the laser 905 is located between the end of the pull rod 501 and the clamping head 814, the laser 905 can completely cut the round tube 7 during the process of cutting the round tube 7 by the laser 905, thereby avoiding the phenomenon that the round tube 7 is broken due to its own gravity during the process of cutting the round tube 7 by the laser 905, resulting in large burrs on the cut surface of the round tube 7;

[0047] When the clamping head 814 clamps the round tube 7, the round tube 7, the clamping connection assembly 8, the cutting assembly 9 and the workbench 4 form a whole, so the round tube 7 and the cutting assembly 9 achieve synchronous movement, thereby improving the cutting accuracy of the laser 905.

[0048] It should be noted that the bed frame 2 and the workbench 4 in the present invention are arranged in a split type, the bed frame 2 is a hollow structure, and the guide rod 3 and the workbench 4 are installed in the middle of the bed frame 2, so that the workbench 4 and the bed frame 2 can be arranged separately.

[0049] See also Figure 5-Figure 6A driving motor 804 is installed on the clamping disk 801, and the output end of the driving motor 804 is connected to a gear 805. A gear ring 808 is installed on the turntable 806, and the gear 805 is meshed with the gear ring 808. An annular groove 803 is opened inside the clamping disk 801, and an annular slider 807 is installed on the turntable 806. The annular slider 807 is slidably installed inside the annular groove 803.

[0050] It should be noted that, by starting the driving motor 804 to drive the gear 805 to rotate, the gear 805 is meshed with the gear ring 808, and the driving motor 804 drives the rotating disk 806 and the round tube 7 fixed on the rotating disk 806 to rotate.

[0051] See also Figure 6 A telescopic pressure rod 817 is installed on the vertical groove 816, and the end of the telescopic pressure rod 817 is connected to the connecting rod 815.

[0052] It should be noted that the telescopic pressure rod 817 can support the connecting rod 815 so that the clamping head 814 on the connecting rod 815 is fixed at a specified position, and the telescopic pressure rod 817 can reset the connecting rod 815 at the same time.

[0053] See also Figure 4 and Figure 7 ,, a slide 802 is installed on the workbench 4, and a slide groove 813 is opened on the slide 802. A slider 809 is slidably installed inside the slide groove 813. Electromagnetic suction cup 1 811 and electromagnetic suction cup 2 812 are respectively installed at both ends of the slider 809. A fixed head 810 is slidably installed inside the slider 809, and the clamping plate 801 is fixedly installed on the fixed head 810.

[0054] It should be noted that, in the initial state, electromagnetic suction cup 1 811 is started, electromagnetic suction cup 2 812 is closed, and electromagnetic suction cup 1 811 connects the fixed head 810 and the clamping plate 801 thereon with electromagnetic suction cup 1 811; when the laser 905 completely cuts the round tube 7, electromagnetic suction cup 1 811 is closed, and electromagnetic suction cup 2 812 is started. At this time, electromagnetic suction cup 2 812 connects the fixed head 810, thereby driving the fixed head 810 to shift inside the slider 809. During this process, the clamping plate 801 on the fixed head 810 drives the pull rod 501 to shift, so that the push block 507 and the pressure block 505 are separated from the round tube 7, completing the blanking work of the round tube 7.

[0055] Grinding sheets or balls can be installed on the push block 507 and the pressing block 505. If the burrs on the end of the round tube 7 need to be polished, grinding sheets need to be installed on the push block 507 and the pressing block 505. When the turntable 806 drives the round tube 7 to rotate, the pull rod 501 is fixed, and the burrs on the end of the round tube 7 are polished by the grinding sheets on the push block 507 and the pressing block 505.

[0056] If the end of the round tube 7 is cut smoothly, it is not necessary to grind the burrs on the end of the round tube 7 , that is, balls are installed on the push block 507 and the pressure block 505 .

[0057] See also Figure 8 and Fig.12 A fixed table 907 is installed on the workbench 4, a cutting disc 901 is fixedly installed on the fixed table 907, a blocking sleeve 12 is installed on the workbench 4, a clamping connection assembly 8 and a cutting assembly 9 are installed inside the blocking sleeve 12, and a blanking assembly 6 is installed on the frame shell 1.

[0058] Specifically, the blanking assembly 6 includes a support platform 601 , an arc plate 602 is installed on the support platform 601 , a rotating rod 603 is rotatably installed on the arc plate 602 , a cylinder 604 is installed on the support platform 601 , and an output end of the cylinder 604 is connected to the rotating rod 603 .

[0059] It should be noted that when the laser 905 works faster, the blanking speed of the round tube 7 also needs to match the laser 905, that is, the inclination angle of the rotating rod 603 away from the end of the arc plate 602 is adjusted by the cylinder 604, thereby controlling the blanking speed of the round tube 7.

[0060] See also Figure 10-11 The positioning and correction component 5 also includes an L-shaped rod 504, a mounting groove 503 is provided on the pull rod 501, the L-shaped rod 504 is rotatably installed inside the mounting groove 503, one end of the L-shaped rod 504 is connected to a pressure block 505, the pressure block 505 is in contact with the outer wall of the circular tube 7, and a connecting block 506 is installed at the other end of the L-shaped rod 504. The connecting block 506 is connected to a push block 507 through a push rod 508, the end of the circular tube 7 abuts against the push block 507, and a compression spring 509 is installed on the push block 507.

[0061] Specifically, a vertical slide rail 902 is installed on the cutting disk 901, a horizontal slide rail 904 is slidably installed on the vertical slide rail 902, a laser 905 is slidably installed on the horizontal slide rail 904, the horizontal slide rail 904 on the vertical slide rail 902 is driven by a vertical motor 903, and the laser 905 on the horizontal slide rail 904 is driven by a horizontal motor 906.

[0062] It should be noted that, when the laser 905 of the prior art is ring-cutting the round tube 7, the rotation angle of the laser 905 is slightly greater than 360 degrees, so it is necessary to consider the problem of the laser 905's line interference and the problem of the round tube 7 falling and damaging the laser 905, which makes the work of arranging the laser 905 extremely cumbersome;

[0063] The laser 905 is adjusted to a suitable position by means of the vertical slide rail 902 and the horizontal slide rail 904, and the drive motor 804 is started. The drive motor 804 drives the turntable 806 to rotate through the engagement of the gear 805 and the gear ring 808. The turntable 806 drives the circular tube 7 to rotate through the connecting rod 815, and at the same time cooperates with the laser 905 to perform circular cutting of the circular tube 7. The circular tube 7 rotates by itself and cooperates with the laser 905 to perform circular cutting, thereby simplifying the layout of the laser 905.

[0064] In actual use, the self-rotation of the circular tube 7 in conjunction with the circular cutting method of the laser 905 has the following problems: if the circular tube 7 is not concentric with the clamping connection component 8 and the cutting component 9, that is, the end of the circular tube 7 at the entry end is inclined, even if the clamping head 814 clamps the circular tube 7, it is difficult to effectively correct the end of the circular tube 7. As the turntable 806 drives the circular tube 7 to rotate, the end of the circular tube 7 will move in a circular trajectory, causing the distance between the laser 905 and the circular tube 7 to change dynamically, resulting in uneven cutting of the circular tube 7 by the laser 905.

[0065] See also Fig.11 After passing through the cutting disk 901, the round tube 7 contacts and presses the push block 507. The push block 507 drives the L-shaped rod 504 to rotate through the push rod 508 and the connecting block 506. The L-shaped rod 504 presses the outer wall of the end of the round tube 7 through the pressing block 505 to correct the inclination angle of the end of the round tube 7, so that the distance between the laser 905 and the round tube 7 is constant, ensuring that the laser 905 can cut the round tube 7 evenly.

[0066] See also Figure 1-Figure 10 As shown, the present invention is a cutting method of a split cutting machine, the method is applied to the split cutting machine as described in the above embodiment, and the method comprises the following steps:

[0067] Step S1: The round tube 7 passes through the clamping disk 801 and the cutting disk 901 in sequence. After passing through the cutting disk 901, the round tube 7 contacts the end of the pull rod 501. As the round tube 7 moves, the round tube 7 drives the pull rod 501 to move synchronously. The pull rod 501 drives the clamping disk 801 to move through the connector 502.

[0068] Step S2: During the sliding of the clamping plate 801, the connecting rod 815 inside the clamping plate 801 rotates inwardly. As the connecting rod 815 rotates, the clamping head 814 on the connecting rod 815 presses and clamps the outer wall of the circular tube 7, so that the clamping connection assembly 8 is connected to the circular tube 7;

[0069] Step S3: Under the clamping of the clamping head 814, the round tube 7 between the end of the pull rod 501 and the clamping head 814 is fixed. When the clamping head 814 clamps the round tube 7, the round tube 7, the clamping connection assembly 8, the cutting assembly 9 and the workbench 4 form a whole.

[0070] like Figure 9-11As shown, as a preferred embodiment of the present invention, the step S1 specifically includes the following steps:

[0071] Step S11: After passing through the cutting disc 901, the round tube 7 contacts and presses the push block 507, and the push block 507 drives the L-shaped rod 504 to rotate through the push rod 508 and the connecting block 506, and the L-shaped rod 504 presses the outer side wall of the end of the round tube 7 through the pressing block 505;

[0072] Step S12: The pressing block 505 presses the side wall of the end of the circular tube 7 so that the pressing block 505 corrects the inclination of the end of the circular tube 7 and makes the distance between the laser 905 and the circular tube 7 constant.

[0073] The implementation principle of the present invention is:

[0074] When in use, the round tube 7 passes through the clamping disk 801 and the cutting disk 901 in sequence under the action of the feeding device, and the clamping head 814 is attached to the outer wall of the round tube 7. After the round tube 7 passes through the cutting disk 901, it contacts and presses the push block 507. The push block 507 drives the L-shaped rod 504 to rotate through the push rod 508 and the connecting block 506. The L-shaped rod 504 presses the outer wall of the end of the round tube 7 through the pressing block 505 to correct the inclination angle of the end of the round tube 7, so that the laser 905 is aligned with the round tube 7. The distance between the tubes 7 is constant, ensuring that the laser 905 can cut the tube 7 evenly. At the same time, the tube 7 drives the pull rod 501 to move synchronously. During this process, the pull rod 501 drives the clamping plate 801 to move through the connecting head 502, so that the clamping plate 801 slides along the slide groove 813 on the slide table 802. During the sliding process of the clamping plate 801, since the clamping head 814 is attached to the outer wall of the tube 7, the connecting rod 815 inside the clamping plate 801 rotates inwards, as shown in FIG. Figure 6 As shown, as the connecting rod 815 rotates, the clamping head 814 on the connecting rod 815 presses and clamps the outer wall of the round tube 7, so that the clamping connection assembly 8 is connected to the round tube 7. Under the clamping of the clamping head 814, the round tube 7 between the end of the pull rod 501 and the clamping head 814 is fixed, see Fig. 9 Since the laser 905 is located between the end of the pull rod 501 and the clamping head 814, the laser 905 can completely cut the round tube 7 during the process of cutting the round tube 7 by the laser 905, thereby avoiding the phenomenon that the round tube 7 breaks due to its own gravity during the process of cutting the round tube 7, resulting in large burrs on the cut surface of the round tube 7, and avoiding the cut pieces of the round tube 7 falling and damaging the laser 905;

[0075] When the clamping head 814 clamps the round tube 7, the round tube 7, the clamping connection assembly 8, the cutting assembly 9 and the workbench 4 form a whole, so the round tube 7 and the cutting assembly 9 achieve synchronous movement, thereby improving the cutting accuracy of the laser 905;

[0076] Next, the laser 905 is adjusted to a suitable position through the vertical slide rail 902 and the horizontal slide rail 904, and the drive motor 804 is started. The drive motor 804 drives the turntable 806 to rotate through the engagement of the gear 805 and the gear ring 808. The turntable 806 drives the round tube 7 to rotate through the connecting rod 815. At the same time, the laser 905 is used to cut the round tube 7 to avoid the problem of interference of the laser 905 line beam and simplify the layout of the laser 905.

[0077] When the laser 905 completely cuts the round tube 7, the round tube 7 moves to the top of the blanking assembly 6, the electromagnetic chuck 1 811 is closed, and the electromagnetic chuck 2 812 is started, so that the electromagnetic chuck 2 812 is connected to the fixed head 810, thereby driving the fixed head 810 to shift inside the slider 809, see Figure 7 During this process, the clamping plate 801 on the fixed head 810 drives the pull rod 501 to shift, so that the push block 507 and the pressure block 505 are separated from the round tube 7, and the cut pieces of the round tube 7 are dropped through the blanking assembly 6. Then, the driving device at the bottom of the workbench 4 quickly moves the workbench 4 to the initial position, so that the clamping connection assembly 8 and the cutting assembly 9 repeat the above operation.

[0078] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
