Description

Technical Field

[0001] This utility model relates to a receiving rack for a laser cutting machine. Background Technology

[0002] Laser cutting machines are widely used in pipe processing due to their high cutting precision and efficiency. During pipe cutting, the cut pipe needs to be moved away from the workpiece promptly to avoid interfering with subsequent cutting actions and ensure the continuity of the processing flow.

[0003] Currently, manual unloading is the primary method for unloading materials after pipe cutting. Manual unloading not only requires dedicated operators, increasing labor costs and intensity, but also makes it difficult for operators to precisely control the stress and movement trajectory of the pipe during handling. This can easily lead to scratches and deformation of the pipe surface, especially for pipes with high precision requirements, directly impacting product quality.

[0004] To address the issue of manual unloading, some manufacturers have attempted to use simple receiving racks for assisted unloading. However, existing receiving racks have significant drawbacks: First, they lack adaptability, as most are designed only for pipes of specific sizes and cannot meet the receiving needs of pipes of different lengths and diameters, resulting in insufficient versatility. Second, the unloading method is unreasonable, often employing a direct drop unloading method where the pipe falls directly from the receiving rack into the material frame, resulting in significant impact during the fall and potential damage to the pipe ends. Third, the level of automation is low, requiring manual adjustment of the receiving position and failing to synchronize with the cutting rhythm of the laser unloading machine, thus limiting unloading efficiency.

[0005] Therefore, developing a material receiving and unloading device that can replace manual labor, adapt to various pipe sizes, reduce pipe damage, and has a high degree of automation has become an urgent technical problem to be solved in this field. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies, such as low efficiency and easy damage to pipes due to manual unloading, as well as poor adaptability and low automation of existing receiving racks. It provides an adaptive receiving and unloading device for laser cutting machines, enabling automated receiving and unloading of pipes after cutting. This device is adaptable to pipes of different lengths and diameters, reduces pipe damage, and improves processing efficiency. The specific technical solution is as follows:

[0007] A receiving frame for a laser cutting machine includes a fixed bracket, a movable bracket, a first rotating frame, and a second rotating frame;

[0008] A fixed bracket, comprising a lower housing and an upper housing, wherein the upper housing and the lower housing are slidably connected in the horizontal direction;

[0009] A movable support frame, which is slidably connected to the upper housing in the vertical direction;

[0010] The first rotating frame, one end of which is hinged to the end of the movable support;

[0011] The second rotating frame has one end hinged to the end of the first rotating frame away from the movable support, and the top of the second rotating frame is provided with a positioning groove.

[0012] The moving mechanism includes a first driving component for driving the movable support to move vertically relative to the upper housing, and a second driving component for driving the upper housing to move horizontally relative to the lower housing.

[0013] The flipping mechanism includes a first actuating component for driving a first rotating frame to flip about a hinge point, and a second actuating component for driving a second rotating frame to flip about a hinge point.

[0014] Furthermore, the first drive assembly includes a vertical rack, a first motor, and a first transmission gear; the vertical rack is vertically fixed to the outer side wall of the upper housing, the first motor is fixed to the movable bracket, the first transmission gear is installed on the output shaft of the first motor and meshes with the vertical rack, and the first motor is a servo motor.

[0015] This component, through the high-precision control of the servo motor and the stable transmission of the rack and pinion, can drive the movable bracket to achieve precise vertical movement relative to the upper housing. The receiving height can be flexibly adjusted according to the diameter of the pipe to be received, avoiding pipe misalignment due to height deviation. The closed-loop control of the servo motor can also ensure the stability of the position after height adjustment, providing a reliable guarantee for subsequent receiving.

[0016] Furthermore, the second drive assembly includes a transverse rack, a second motor, and a second transmission gear; the transverse rack is horizontally fixed to the top of the lower housing, the second motor is fixed to the bottom of the upper housing, the second transmission gear is mounted on the output shaft of the second motor and meshes with the transverse rack, and the second motor is a servo motor.

[0017] This component, through the cooperation of a servo motor and a horizontal rack and pinion, can drive the upper housing to move smoothly horizontally relative to the lower housing. It can adjust the horizontal receiving range of the receiving rack according to the pipe length, adapting to the receiving needs of pipes of different lengths. At the same time, the precise drive of the servo motor can avoid jamming or positional deviation during horizontal movement, ensuring that the receiving rack can be accurately aligned with the discharge end of the laser cutting machine.

[0018] Furthermore, the first actuating component is a first cylinder, the cylinder body of the first cylinder is hinged to the lower surface of the movable bracket, and the piston rod of the first cylinder is hinged to the lower surface of the first rotating frame; the second actuating component is a second cylinder, the cylinder body of the second cylinder is hinged to the lower surface of the first rotating frame, and the piston rod of the second cylinder is hinged to the lower surface of the second rotating frame; both the first cylinder and the second cylinder are pneumatic cylinders with position feedback, and the rotation angle range is 0-90°.

[0019] The pneumatic cylinder with position feedback can monitor the flipping position in real time. Through the relay drive of two cylinders, the flipping angle of the first and second rotating frames can be precisely controlled. The flipping range of 0-90° can meet the needs of different unloading scenarios, avoid the pipe falling directly and causing damage, and realize the pipe sliding smoothly along the rotating frame to the material frame, improving the safety and stability of unloading.

[0020] Furthermore, the surface of the first rotating frame is provided with a guiding mechanism, which includes a plurality of follower rollers. The follower rollers are evenly arranged along the pipeline conveying direction, and the axis of the follower rollers is perpendicular to the pipeline conveying direction. The follower rollers are rotatably mounted on the upper surface of the first rotating frame through bearing seats.

[0021] The follow-up rollers can rotate synchronously with the pipeline, converting the sliding friction between the pipeline and the rotating frame into rolling friction, which greatly reduces friction and scratches on the pipeline surface. The evenly arranged rollers can also provide stable support for the pipeline, preventing it from shifting during pipeline transportation, ensuring that the pipeline accurately enters the subsequent positioning groove, and improving the smoothness of the material receiving process.

[0022] Furthermore, the upper surface of the positioning groove has an arc-shaped structure, and the radius of curvature of the arc-shaped structure is 1.05-1.2 times the outer diameter of the pipe to be received; the inner wall of the positioning groove is provided with an elastic buffer layer, which is made of rubber or polyurethane.

[0023] The curved structure can fit the outer wall of the pipe, and the curvature radius of 1.05-1.2 times ensures that the pipe can be smoothly inserted and avoids the pipe from shaking in the groove, achieving precise positioning; the elastic buffer layer of rubber or polyurethane can absorb the impact force when the pipe is inserted, reduce the collision damage between the pipe end and the groove, and protect the pipe processing accuracy.

[0024] Furthermore, a horizontal guide assembly is provided between the upper housing and the lower housing. The horizontal guide assembly includes a first guide rail and a third guide rail. Both the first guide rail and the third guide rail are fixed to the upper housing, and the sliders in the first guide rail and the third guide rail are fixed to the lower housing.

[0025] A vertical guide assembly is provided between the movable support and the upper housing. The vertical guide assembly includes a second guide rail, which is fixed to the upper housing, and a slider in the second guide rail is fixed to the movable support.

[0026] Furthermore, a control system is included, comprising a PLC controller and a position sensor; the position sensor is used to detect the horizontal and vertical positions of the movable support; the PLC controller is electrically connected to the first motor, the second motor, the first cylinder, the second cylinder, and the position sensor, and is linked with the control system signal of the laser cutting machine.

[0027] Furthermore, the lower housing of the fixed bracket is fixedly connected to the frame of the laser cutting machine by bolts; both the first rotating frame and the second rotating frame adopt a lightweight alloy frame structure, and the frame surface is provided with an anti-rust coating.

[0028] Bolted connections ensure a secure fixation between the fixed bracket and the laser cutting machine frame, preventing bracket wobbling during material receiving and affecting receiving accuracy; the lightweight alloy frame reduces the weight of the rotating frame, lowers the cylinder drive load, and extends cylinder life; the anti-rust coating isolates air, moisture, and cutting debris, preventing the rotating frame from rusting, improving the equipment's corrosion resistance, and extending the overall service life.

[0029] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0030] 1. It has wide adaptability and can meet the material receiving and unloading needs of pipes of different lengths and diameters. Through the multi-dimensional position adjustment of the moving mechanism, combined with the arc structure design of the positioning groove, it can achieve precise positioning of pipes of different specifications.

[0031] Second, the pipeline damage rate is significantly reduced. The friction damage during pipeline transportation is reduced by the follow-up roller. The elastic buffer layer and arc structure in the positioning groove can buffer the impact force when the pipeline is placed. The smooth flipping and unloading of the flipping mechanism avoids the collision damage caused by free fall.

[0032] Third, the operation is stable and reliable. The horizontal and vertical guide components ensure the accuracy of the movement of each support. The cylinder and servo motor ensure the precision of motion control. The lightweight alloy frame and anti-rust coating design extend the service life of the device and reduce maintenance costs.

[0044] Workflow

[0045] S1. Material Receiving Preparation: After the laser cutting machine sends a cutting completion signal, the PLC controller receives the signal and controls the second motor 7 to start according to the length and diameter parameters of the pipe to be received. The second motor 7 drives the upper housing to move horizontally relative to the lower housing through the engagement of the horizontal rack and the second transmission gear, adjusting the horizontal position of the receiving material. At the same time, the first motor 6 is controlled to start, and the first motor 6 drives the movable bracket 2 to move vertically relative to the upper housing through the engagement of the vertical rack 10 and the first transmission gear, adjusting the receiving height until the positioning groove is aligned with the outlet end of the pipe.

[0046] S2. Pipe receiving: After the pipe is cut, it is conveyed along the discharge guide rail of the laser cutting machine to the follower roller 5 of the first rotating frame 3. The follower roller 5 moves and rotates with the pipe to reduce friction.

[0047] S3, Tilting and Unloading: Based on the pipeline positioning signal fed back by the position sensor, the PLC controller controls the first cylinder 8 and the second cylinder 9 to operate in sequence, driving the first rotating frame 3 and the second rotating frame 4 to rotate. The rotation angle gradually increases to 60°. The pipeline first enters the arc-shaped surface of the positioning groove and finally slides smoothly into the material frame.

[0048] S4. Reset and standby: After unloading is completed, the first cylinder 8 and the second cylinder 9 are reset, driving the first rotating frame 3 and the second rotating frame 4 back to the initial horizontal position; the first motor 6 and the second motor 7 drive the movable bracket 2 and the upper housing to reset, waiting for the next material receiving command.
