Description

Technical Field

[0001] The present invention relates to the technical field of automatic cutting, and particularly relates to an automatic cutting device convenient for positioning. Background Art

[0002] Plasma arc cutting is to pass a mixed gas through a high-frequency arc. The gas can be air, or a mixed gas of hydrogen, argon, and nitrogen. The high-frequency arc causes some gases to "decompose" or ionize into basic atomic particles, thus generating "plasma". Then, the arc jumps to the stainless steel workpiece, and the high-pressure gas blows the plasma out of the cutting torch nozzle at an outlet speed of 800 - 1000 meters per second (about 3 Mach). In this way, combined with the high energy released when various gases in the plasma return to the normal state, a high temperature of 2700 °C is generated. This temperature is almost twice the melting point of stainless steel. Thus, the stainless steel melts quickly, and the molten metal is blown away by the ejected high-pressure air flow.

[0003] Chinese Patent CN2022107520853 discloses a plasma automatic cutting device. The input end of the control box is respectively connected to an air compressor and a plasma power supply; the output end of the control box is connected to a cutting gun adjustment device. An upper pipe lifting device is provided on the cutting gun adjustment device. One side of the upper pipe lifting device is connected to a pipe clamping large disc, and a pipe to be cut is provided on the pipe clamping large disc. Using this device can complete the automatic processing of the pipe diameter bevel, ensuring the processing uniformity and consistency of the bevel, with high production efficiency and no safety hazards; the 1-ton crane can rotate 360° freely, and the weight of the lifted pipe circle is about 2000 Kg, solving the hoisting problem of large-diameter pipes; the cutting gun adjustment device enables the cutting gun to be longitudinally adjusted along the pipe diameter to adapt to the pipe diameter change range.

[0004] However, this technical solution does not have the function of automatic workpiece positioning. During the cutting process, the workpiece needs to be manually fixed, which affects the processing efficiency and brings certain risks to the staff. Therefore, we propose an automatic cutting device convenient for positioning. Summary of the Invention

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

[0043] Embodiment 1: As Figures 1 - 16 shown, this embodiment provides an automatic cutting device that is convenient for positioning, including a device base 1, and further including a processing top plate 2 on the top of the device base 1.

[0051] In this embodiment, the two groups of limiting rods 706 can limit the switch lever 705 and contact the workpiece after the feeding is completed through the force-receiving rod 707, so that the switch lever 705 is stably triggered. When the force-receiving rod 707 moves backward along the fixed sleeve 708 under force, the return spring 710 can be compressed, and the generated resilience can reset the force-receiving rod 707 after the cutting is completed and the blanking is carried out.

Furthermore, the moving trigger block 713 can be pushed in the limiting sliding seat 711 to overcome the resilience of the docking spring 715 on the outer docking rod 714, so that the moving metal block 721 contacts the fixed metal block 716, and the power wire 722 and the output wire 720 are connected, further making the electromagnetic structure energized to adsorb and fix the workpiece reaching the designated position.

[0065] Working steps

[0066] Step 1, feeding process: Driven by the feeding motor 304, and through the transmission between the feeding pulley 305 and the feeding belt 306, the driving upper feeding roller 302 rotates, and through the tensioning and guiding of multiple groups of driven upper feeding rollers 303, the movement of the feeding conveyor belt 307 is realized, moving the workpiece to the processing top plate 2, and through the electric pushing device 11 to push, the workpiece is fed into the processing area;

[0067] Step 2, positioning process: Push the workpiece in the processing area towards the processing position through the outer pushing device. When the workpiece contacts the U-shaped longitudinal slide plate 603, the U-shaped longitudinal slide plate 603 is stressed and will move backward along the longitudinal displacement slide rail 601. Thus, two traction connecting rods 613, which are movably connected to the outside of two longitudinal handle pins 610 at the bottom of the longitudinal extension plate 609, can be used to pull the horizontal displacement sliders 606 at the bottom of the two horizontal positioning plates 605 to approach the center of the limit top plate 4 along the horizontal displacement slide rail 604, and when the workpiece reaches the specified position, it will be close to the workpiece to initially clamp and position the workpiece;

[0068] Step 3, fixing process: When the workpiece is positioned and moved to the specified position, it will contact the stress rod 707. The stress rod 707 moves backward on the fixed sleeve 708 against the resilience of the return spring 710, and through the switch plate 705, the movable switch 702 rotates along the switch movable shaft 703 to lift the switch roller 704, and further in the limit slide seat 711, the movable trigger block 713 is pushed to displace against the resilience of the docking spring 715 on the outer docking rod 714, so that the movable metal block 721 contacts the fixed metal block 716 to connect the power supply line 722 and the output line 720, making the electromagnetic wire 726 energized to form a magnetic field and endowing the electromagnet block 725 with magnetic force to fix the workpiece that reaches the specified position;

[0069] Step 4, cutting process: Drive the output gear 504 to rotate through the longitudinal walking motor 503. The output gear 504 meshes with and drives the longitudinal driving gear set 505 to rotate. The longitudinal driving gear set 505 meshes with the longitudinal fixed rack 508, and through the guiding of the longitudinal driven gear set 506 and the longitudinal walking slider 507, the overall walking of the cutting cross beam 501 is realized to adjust the longitudinal position of the cutting device; Drive the horizontal walking gear set 512 to rotate along the horizontal fixed rack 513 through the horizontal walking motor 511 to adjust the horizontal position of the cutting device; Drive the driving screw rod 517 to rotate through the vertical adjustment motor 516, and through the connection between the screw nut 518 and the driving screw rod 517 and the guiding of the slider to adjust the vertical position of the cutting device; Adjust the angle of the cutting device through the driving of the motors in the main deflection seat 521 and the secondary deflection seat 522 on the U-shaped mounting seat 519, and finally start the plasma cutting head 523 for cutting;

[0070] Step 5, retraction process: The push plate 804 is pushed by the push cylinder 806 to move, and the two sets of guide rods 807 are ensured to be stable along the corresponding sliding sleeves, and the cut workpiece is pushed to the initial position. At the same time, the upper block of the cylinder output rod can contact the back of the switch plate 705 to reset the switch. At the same time, the push plate 804 can push the U-shaped longitudinal slide plate 603 to reset, and the traction connecting rod 613 below it drives the two sets of horizontal positioning plates 605 to reset;

[0071] Step 6, translational unloading process: driven by the traction motor 904, the traction of the traction pulley 905 and the traction belt 906 realizes the driving of the two sets of traction wheels 903 on the traction shaft 901 on the traction bearing plate 902, and further through the friction between the two sets of traction wheels 903 and the workpiece retreated to the specified position, the workpiece is translated out of the processing area and contacted with the conveyor belt of the unloading device 10, and the cut workpiece is transported out after being driven by the motor in the unloading device 10.
