Description

Technical Field

[0001] This utility model relates to the field of laser tube cutting equipment technology, and more specifically to a fully automatic feeding beveling laser cutting equipment. Background Technology

[0002] Laser tube cutting equipment is widely used in metal processing, pipe manufacturing, and welding industries. Its main function is to cut metal tubes at high speed and with high precision. However, existing technologies have some problems; such as low loading efficiency and high labor costs. Traditional laser tube cutting machines usually rely on manual placement of tubes one by one onto the cutting machine for processing, and manual loading is required after each cut. This not only results in low work efficiency but also increases labor costs, especially when processing long tubes or in batch production, where efficiency bottlenecks are obvious. Another problem is unstable tube support, which affects cutting accuracy. Traditional follow-up support devices are usually fixed on the machine bed, and each support component needs to be individually adjusted in height to accommodate tubes of different diameters, making operation complex and debugging time long. Tubes of different diameters are prone to shaking during the cutting process, leading to decreased cutting accuracy and increased defect rate. Furthermore, it is difficult to process the beveling of the tube end face. Traditional laser tube cutting machines mostly cut straight or at a fixed angle when cutting tubes, and cannot achieve flexible beveling. This can easily lead to unstable weld joints and poor weld quality in subsequent welding processes. In addition, in existing equipment, the feeding, supporting, clamping and cutting components are usually adjusted independently, lacking linkage and unified control. The equipment is complicated to operate and inconvenient to debug, making it difficult to achieve fully automated and precise production. Utility Model Content

[0003] In view of this, the present invention provides a fully automatic feeding and beveling laser cutting equipment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fully automatic feeding and beveling laser cutting equipment includes: a bed body; a fully automatic feeding rack fixed on the bed body for automatically feeding pipes to the cutting station; a follow-up component on the bed body for lifting and adjusting the height of pipes of different diameters; a rear clamping component and a front clamping component for clamping and positioning the pipes; and a cutting head assembly including a Z-axis motor, an X-axis motor, a beveling motor, and a cutting head, wherein the beveling motor can drive the cutting head to rotate ±45° around the Y-axis to achieve beveling cutting of the pipes.

[0006] In a preferred embodiment, the fully automatic feeding rack includes a stretching mechanism, which comprises a stretching motor, a stretching belt, and multiple roller mechanisms. The stretching motor drives the stretching belt to convey the pipe. A feeding inclined column is used to support and guide the pipe down to the cutting machine tool. A first baffle assembly includes a first cylinder and a baffle plate for blocking or releasing the pipe. A pushing assembly includes a pushing cylinder and a pushing plate for pushing excess pipe back onto the stretching belt, and the pushing stroke is adjusted by a screw.

[0007] In the preferred technical solution, the fully automatic feeding rack also includes a stacking component, which pushes the stacked pipes by a cylinder-driven push plate, and its mounting hole is a combination of elongated hole and tapping hole, which can be adjusted up and down to adapt to pipes of different diameters; the second and third blocking components are both equipped with cylinder-driven blocking plates to progressively restrict the pipes from sliding down and achieve precise positioning of a single pipe.

[0008] In a preferred embodiment, the follower assembly includes a follower motor for driving the follower screw to rotate; the follower screw is connected to a follower adapter plate, which drives the follower inclined pressure plate to move along the Y-axis; a follower cylinder drives the follower roller to rise and fall, thereby supporting the pipe; and a follower bearing is located at the limiting position of the inclined pressure plate to limit the rising height of the follower cylinder to adapt to pipes of different diameters.

[0009] In a preferred embodiment, the follower component is provided with front and rear clamping shafts for clamping the pipe and driving the pipe to rise and fall synchronously when the follower cylinder rises.

[0010] In the preferred technical solution, the follower component adjusts the position of the follower inclined pressure plate by means of a limit screw or adjustment mechanism, thereby controlling the rising height of the follower cylinder to adapt to the height lifting of pipes of different diameters.

[0011] In a preferred embodiment, the rear clamping assembly includes a jaw structure that moves along the Y-axis for clamping and conveying the pipe to the front clamping assembly; the front clamping assembly is provided with a clamping device for receiving the pipe and maintaining its processing position.

[0012] In a preferred embodiment, the front clamping assembly further includes a rotating mechanism that can drive the pipe to rotate around its own axis, used to adjust the pipe end face angle to accommodate beveling.

[0013] In a preferred embodiment, the Z-axis motor in the cutting head assembly drives the cutting head to move up and down along the Z-axis direction, and the X-axis motor drives the cutting head to move horizontally along the X-axis direction, so as to achieve three-dimensional cutting.

[0014] In the preferred embodiment, the beveling motor is connected to the cutting head via a slewing bearing or a rotating mechanism, enabling it to rotate within a range of 0° to 45° to bevele the pipe end face, thereby facilitating subsequent welding. During the cutting process, the clamping action of the front and rear clamping components and the lifting action of the follower component ensure stable positioning of the pipe, thereby improving cutting accuracy and reducing the occurrence of defective products.

The cutting head assembly, equipped with a beveling motor, allows the cutting head to rotate ±45° around the Y-axis, enabling beveling of the pipe end face, making subsequent welding joints easier to fit, improving welding quality and yield. The feeding rack and follow-up assembly, through cylinders, screws, elongated holes, and adjustable slide rails, adapt to pipes of different diameters and lengths, ensuring stable operation during batch processing and improving equipment versatility and flexibility.

In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] This embodiment provides a fully automatic feeding and beveling laser cutting device. Please refer to [link / reference]. Figure 1-10 The system includes a bed body 1, a fully automatic feeding rack 2, a follow-up assembly 3, a rear clamping assembly 4, a front clamping assembly 5, and a cutting head assembly 6. The bed body 1 is a welded steel structure or a high-strength casting frame, equipped with X-axis, Y-axis, and Z-axis linear guides to support and position the various functional components, ensuring overall rigidity and repeatability. The fully automatic feeding rack 2 is fixed to the bed body 1 and mainly includes a tensioning motor 201, a tensioning belt 206, a first stop assembly 202, a second stop assembly 205, a third stop assembly 208, a pusher assembly 204, a lead screw 207, and a stacking assembly 203. The tensioning motor 201 drives the tensioning belt 206 to rotate via a reduction mechanism, realizing the conveying of the pipe from the hopper to the top of the feeding inclined column. The tensioning belt 206 is equipped with multiple roller mechanisms, each roller can rotate and support the bottom of the pipe, achieving uniform lifting. The rollers, in conjunction with the tensioning belt, can buffer the vibration of the pipe during upward movement.

[0033] Furthermore, the first baffle assembly 202 prevents the pipe from slipping by moving up and down with a cylinder, and is simultaneously connected to the pusher assembly 204. The pusher assembly 204 pushes the pipe back and forth with a cylinder, and the lead screw 207 is used to adjust the cylinder stroke so that a row of pipes remains on the inclined column after being pushed, providing a continuous supply for the follow-up lifting mechanism. The stacking assembly 203 is driven up and down by a cylinder to stack multiple rows of pipes and fix them through tapped holes. The elongated hole design can be adjusted up and down to accommodate pipes of different diameters. The second baffle assembly 205 and the third baffle assembly 208 are arranged below the inclined column. The pipes slide from the stacking assembly 203 to the baffle assembly 205, and then to the baffle assembly 208, providing a stable supply for the follow-up assembly 3. The tensioning mechanism and the baffle assemblies work together to achieve automatic feeding of the entire bundle of pipes. The operator only needs to place or hoist the pipes into the material rack area without manual intervention. The feeding rack 2 is equipped with multiple photoelectric sensors to detect the position of the pipes, triggering blocking, pushing and stacking actions. At the same time, it communicates with the equipment control system PLC to realize fully automatic continuous feeding.

[0034] Furthermore, the follower assembly 3 is fixed to the bed body 1 and includes a follower motor 301, a follower lead screw 302, a follower adapter plate 303, a follower inclined pressure plate 304, a follower cylinder 305, a follower roller 306, front and rear clamping shafts 307, and a follower bearing 308. The follower motor 301 drives the follower lead screw 302 to rotate, causing the follower adapter plate 303 to move back and forth, controlling the position of the follower inclined pressure plate 304, and limiting the lifting height of the follower bearing 308 to achieve height adaptation for pipes of different diameters. The follower cylinder 305 drives the follower roller 306 to rise and fall. The roller and the front and rear clamping shafts 307 work together to clamp the pipe, achieving stable lifting and smooth conveying of the pipe. The follower assembly 3 is also equipped with an adjustable slide rail and a limit screw to facilitate adjustment of the lifting height and ensure accurate positioning of the pipe when it is docked with the rear clamping assembly 4 and the front clamping assembly 5. The 306 follower roller uses high-rigidity bearings to reduce rolling friction and vibration, ensuring that the pipe does not shake during transportation and lifting, and improving cutting accuracy.

[0035] Furthermore, the rear clamping assembly 4 moves linearly along the Y-axis, delivering the pipe to the front clamping assembly 5. While clamping and positioning the pipe, the front clamping assembly 5, via its built-in servo motor, can rotate the pipe around its own axis, achieving precise adjustment of the cutting angle. The rotation angle can be automatically controlled according to the CNC program to cooperate with the beveling motor 603 and the cutting head 604 for high-precision beveling. The clamping and rotation functions of the front clamping assembly 5 are linked with the follower assembly 3 to ensure stable positioning and accurate angle of the pipe throughout the entire process of conveying, lifting, and processing, reducing cutting deviations and defective product rates. Both the rear clamping assembly 4 and the front clamping assembly 5 are driven by cylinders or servo motors, and their clamping positions are adjustable to accommodate different pipe diameters and lengths. The clamping and rotation actions are linked with the follower assembly 3 to ensure the stability of the pipe before processing by the cutting head assembly 6.

[0036] Furthermore, the cutting head assembly 6 includes an X-axis motor 602, a Z-axis motor 601, a beveling motor 603, and a cutting head 604. The X-axis motor 602 drives the cutting head to move horizontally on the X-axis guide rail, the Z-axis motor 601 drives the cutting head to move vertically on the Z-axis guide rail, and the beveling motor 603 can rotate the cutting head 604 ±45° around the Y-axis to achieve pipe beveling. The cutting head 604 is a laser cutting head, combined with a high-rigidity guide rail, ball screw, and angle encoder to achieve high-precision positioning, ensuring consistent cutting accuracy and beveling angle. Beveling facilitates subsequent welding, improving welding quality and yield. The movement of the cutting head assembly 6 is controlled by a CNC system, enabling automatic adjustment of different pipe diameters, cutting angles, and beveling angles. It also works in conjunction with the front and rear clamping assemblies and the follow-up assembly to achieve fully automated cutting.

[0037] Control and Safety

[0038] Furthermore, the PLC and CNC controller coordinate the actions of the fully automatic feeding rack 2, the follow-up assembly 3, the clamping assemblies 4 and 5, and the cutting head assembly 6. Photoelectric sensors on the feeding rack and follow-up assembly monitor the position and arrival status of the pipes to prevent material shortages or congestion. The equipment is equipped with safety doors, an emergency stop button, and an interlocking system to ensure operator safety. The control system supports setting processing parameters for different pipe diameters, lengths, and bevel angles, enabling flexible batch processing. Through the above structure, this embodiment achieves fully automatic pipe feeding, high-precision lifting and clamping, bevel cutting, and high-precision processing, suitable for pipes of different diameters and specifications, reducing defect rates and improving production efficiency and safety.

[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
