Description

Technical Field

[0001] This utility model relates to the field of pipe and profile cutting technology, and in particular to a pipe and profile cutting device. Background Technology

[0002] Currently, in the field of pipe and profile processing, cutting operations mostly rely on manual feeding or a single clamping mechanism in conjunction with a cutting machine. Since pipes and profiles are generally long and heavy, manual feeding is not only labor-intensive, but the shaking during the feeding process can easily cause the cutting position to shift, resulting in insufficient cutting accuracy and low processing efficiency.

[0003] Existing automatic cutting equipment typically controls the entry and exit of pipes and profiles through a single rear clamp or pusher mechanism. However, as the material length gradually shortens, the distance between the clamping position and the cutting machine becomes insufficient, and the rear clamping mechanism cannot continue to clamp effectively. At this time, manual readjustment or auxiliary positioning is often required, resulting in discontinuous cutting process and affecting production cycle and automation level.

[0004] Furthermore, when cutting the end of the profile, since the middle clamping mechanism and the blanking mechanism are located on the left and right sides of the cutting equipment, if the middle clamping mechanism is used to clamp the tube or profile and cut the end area directly, it is easy to cause interference with the cutting mechanism or unstable clamping. Some equipment needs to be designed with complex clearance structures or synchronous control mechanisms to avoid interference, which not only increases mechanical complexity but also increases the manufacturing and maintenance costs of the equipment.

[0005] For example, in the case of a drag chain type chuckless laser cutting machine for profiles and pipes described in patent number CN116511735B, when it is necessary to cut the tail material, the tail material handling mechanism in the above-mentioned prior art needs to clamp the tail material and then drive the entire tail material handling mechanism and the clamping mechanism to move to the right in sync to move the tail of the pipe or profile tail material. This increases the distance between the cutting equipment and the tail material handling mechanism, that is, the tail material cutting mechanism moves to the right to make room. The increased distance between the cutting equipment and the tail material handling mechanism causes the length of the profile between the two to increase. When the length of the profile between the two is too long, it will be slightly drooping in the middle due to its own weight, resulting in poor cutting effect.

[0006] Therefore, how to design a cutting device that can automatically switch the clamping position according to the length of the pipe or profile, so as to achieve continuous feeding and avoid interference between the clamping mechanism, the unloading mechanism and the cutting mechanism during end cutting, has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a pipe and profile cutting device.

[0008] The purpose of this utility model is achieved as follows: a pipe and profile cutting device, including a cutting machine, a rear clamping mechanism, a middle clamping mechanism, an end unloading mechanism, and a side clamping mechanism, characterized in that: a support frame is provided on the left side of the cutting machine, and a rear clamping mechanism is provided on the support frame that can move left and right. The rear clamping mechanism is used to clamp the rear end of the pipe and profile, thereby driving the pipe and profile to move left and right.

[0009] A central clamping mechanism is located on the left side of the cutting machine. The central clamping mechanism clamps the profile and can move left and right relative to the cutting machine.

[0010] The cutting machine is equipped with an end feeding mechanism on the right side, and a side clamping mechanism that can move left and right is provided on the end feeding mechanism. The side clamping mechanism clamps the left and right sides of the pipe and profile and drags the pipe and profile to move left and right.

[0011] In use, this application employs a rear-end clamping mechanism to hold the rear end of the pipe or profile, causing it to move left and right. This, in turn, moves the pipe or profile into and out of the cutting machine, where it is cut. If the pipe or profile on the left side of the cutting machine is too short to be held by the rear-end clamping mechanism, the pipe or profile is clamped by the middle clamping mechanism. After the rear-end clamping mechanism releases its grip and resets, the left and right movement of the middle clamping mechanism moves the pipe or profile left and right into and out of the cutting machine, where it is cut.

[0012] When the rear end of a pipe or profile needs to be cut, and the central clamping mechanism cannot hold it, the pipe or profile is positioned on the end unloading mechanism. A side clamping mechanism then clamps the pipe or profile, allowing for proper holding. The central clamping mechanism releases its grip and resets, while the side clamping mechanism moves the profile left and right, enabling the rear end of the pipe or profile to be cut. This technical solution avoids motion interference between the central clamping mechanism and the end unloading mechanism during rear end cutting, eliminating the need for any clearance between them.

[0013] Beneficial effects: This utility model has the following technical effects when used:

[0014] 1. Enables multi-segment clamping switching, improving cutting continuity and adaptability. When the pipe or profile is long, the rear clamping mechanism completes the clamping and feeding operations; when the material length is shortened to the point that the rear clamping mechanism cannot clamp it, the middle clamping mechanism automatically takes over to clamp and feed, achieving continuous cutting without the need for manual repositioning, thus improving production efficiency.

[0015] 2. Achieve interference-free clamping control during the rear-end cutting process. When cutting the end of pipes and profiles, the side clamping mechanism on the end blanking mechanism clamps the workpiece on both sides, allowing the middle clamping mechanism to release and reset, avoiding motion interference between the middle clamping mechanism and the blanking mechanism, thus achieving independence and stability in the end cutting process.

[0016] 3. Improved feeding and positioning accuracy. The multi-point segmented clamping design ensures that the pipes and profiles remain in a stable and controlled state during feeding and cutting, effectively avoiding problems such as shaking and offset caused by single-point clamping, and ensuring cutting dimensional accuracy and cut smoothness.

[0017] 4. Enhance the intelligence and versatility of the equipment. This device uses multiple left-right movable clamping mechanisms to work together, adapting to the processing needs of pipes and profiles of different lengths and cross-sections. This reduces the time spent on manual adjustment and auxiliary positioning, and enhances the versatility and automation of the device.

[0018] 5. Avoid structural interference and simplify control logic. Through reasonable mechanism distribution and clamping sequence control, independent actions between each clamping mechanism are achieved, eliminating the need for additional clearance structures, reducing equipment complexity and control difficulty, and improving overall operational stability and reliability.

Detailed Implementation

[0031] Example 1, such as Figure 1-3 As shown, the purpose of this utility model is to achieve a pipe and profile cutting device, including a cutting machine 4, a rear clamping mechanism 3, a middle clamping mechanism 7, an end unloading mechanism 6, and a side clamping mechanism 2. A support frame 1 is provided on the left side of the cutting machine 4. The rear clamping mechanism 3 is provided on the support frame 1 and can move left and right. The rear clamping mechanism 3 is used to clamp the rear end of the pipe and profile and drive the pipe and profile to move left and right.

[0032] A central clamping mechanism 7 is provided on the left side of the cutting machine 4. The central clamping mechanism 7 clamps the profile and can move left and right relative to the cutting machine 4.

[0033] The cutting machine 4 is equipped with an end feeding mechanism 6 on the right side. The end feeding mechanism 6 is equipped with a side clamping mechanism 2 that can move left and right. The side clamping mechanism 2 clamps the left and right sides of the tube and profile and drags the tube and profile to move left and right.

[0034] In use, this application uses a rear-end clamping mechanism 3 to clamp the rear end of the pipe or profile, causing it to move left and right; this then moves the pipe or profile into and out of the cutting machine 4, where it is cut. If the pipe or profile on the left side of the cutting machine 4 is too short to be clamped by the rear-end clamping mechanism 3, the pipe or profile is clamped by the middle clamping mechanism 7. After the rear-end clamping mechanism 3 releases its grip and resets, the left and right movement of the middle clamping mechanism 7 causes the pipe or profile to move left and right into and out of the cutting machine 4, where it is cut.

[0035] When the rear end of a pipe or profile needs to be cut, and the central clamping mechanism 7 cannot hold the pipe or profile, the pipe or profile is located on the end unloading mechanism 6. The side clamping mechanism then clamps the pipe or profile, achieving this clamping. The central clamping mechanism 7 releases its grip and resets, and the side clamping mechanism moves the profile left and right, thus enabling the rear end of the pipe or profile to be cut. This technical solution avoids motion interference between the central clamping mechanism 7 and the end unloading mechanism 6 when cutting the rear end of the pipe or profile; that is, no yielding operation is required between the central clamping mechanism 7 and the end unloading mechanism 6 to achieve the rear end cutting operation of the pipe or profile.

[0036] This application, by rationally arranging a rear-end clamping mechanism 3, a middle clamping mechanism 7, an end-feeding mechanism 6, and a side clamping mechanism 2 on both sides of the cutting machine 4, forms a structural layout that enables automatic clamping and feeding of pipes and profiles throughout their entire stroke. This layout offers the following advantages: 1. It enables multi-segment clamping switching, improving cutting continuity and adaptability. When the pipe or profile is long, the rear-end clamping mechanism 3 handles the clamping and feeding operations. When the material length shortens to the point where the rear-end clamping mechanism 3 cannot clamp it, the middle clamping mechanism 7 automatically takes over clamping and feeding, achieving continuous cutting without manual repositioning and improving production efficiency. 2. It achieves interference-free clamping control during the rear-end cutting process. During end-cutting of pipes and profiles, the side clamping mechanism 2 on the end-feeding mechanism 6 clamps both sides of the workpiece, allowing the middle clamping mechanism 7 to release and reset, avoiding motion interference between the middle clamping mechanism 7 and the feeding mechanism, thus achieving independence and stability in end-cutting. 3. It improves feeding and positioning accuracy. The multi-point segmented clamping design ensures that pipes and profiles remain stable and controlled during feeding and cutting, effectively avoiding problems such as shaking and offset caused by single-point clamping, and ensuring cutting dimensional accuracy and cut smoothness. 4. Improved equipment intelligence and versatility. This device, through the cooperation of multiple left-right movable clamping mechanisms, can adapt to the processing needs of pipes and profiles of different lengths and cross-sections, reducing the time spent on manual adjustment and auxiliary positioning, and enhancing the device's versatility and automation. 5. Avoided structural interference and simplified control logic. Through reasonable mechanism distribution and clamping sequence control, independent actions between each clamping mechanism are achieved, eliminating the need for additional clearance structures, reducing equipment complexity and control difficulty, and improving overall operational stability and reliability.

[0037] It should be noted that the specific driving methods, transmission forms, and electrical connections of the cutting machine 4, drive motor, control system, transmission mechanism, lifting assembly, limit assembly, and each clamping mechanism in this application can all be implemented using existing mature technologies. Their specific structural forms are not considered innovative points of this application and will not be described in detail here. Those skilled in the art can select conventional driving forms such as pneumatic, hydraulic, electric, or servo drives to achieve clamping, feeding, and resetting actions according to actual needs, as long as they meet the functional requirements of this application. Furthermore, the control logic, action sequence, and signal feedback system of each clamping mechanism in this application can be implemented by existing automated control units or PLC systems, without limiting the circuit structure or program control algorithm; all of these fall within the scope of existing technology.

[0038] For example, the cutting machine 4 can adopt the structure of the cutting machine 4 in a CNC cutting device described in patent number CN107470755A; the structure and driving method of the rear clamping mechanism 3 and the support frame 1 can also adopt the structure of the table body and feeding seat in the above-mentioned technical solutions; the end unloading mechanism 6 can adopt the automatic unloading device for cutting pipes and profiles described in patent number CN215788486U, with a side clamping mechanism 2 set above the end unloading mechanism 6 to clamp the left and right sides of the pipe or profile, and the pipe or profile can be dragged to move left and right. The middle clamping mechanism 7 can adopt the tail material cutting clamping device for CNC cutting equipment described in patent number CN216882739U to clamp the profile, and a driving mechanism is set to drive it to move left and right. Other mechanisms can be implemented by corresponding related technical solutions or replace the related technical solutions of this application.

[0039] Example 2: Figure 4-5 As shown, multiple parallel material-supporting mechanisms 5 are arranged on the front side of the support frame 1. The material-supporting mechanisms 5 drive the profile to move up and down, and cooperate with the rear clamping mechanism 3 to clamp the rear end of the pipe and profile. The material-supporting mechanism 5 includes a placement frame 501, on which are mounted a vertically movable roller 505, a front clamping plate 503, and a rear clamping plate 504. The front clamping plate 503 and the rear clamping plate 504 are located to the left of the roller 505. The front clamping plate 503 and the rear clamping plate 504 can move back and forth, and the front clamping plate 503 and the rear clamping plate 504 move synchronously and in opposite directions. The material-supporting mechanism 5 also includes a lifting plate 507, which is vertically movable and located on the placement frame 501. The roller 505 is rotatably located at the upper end of the lifting plate 507. The front clamping plate 503 and the rear clamping plate 504 are located on the lifting plate 507. The front clamping plate 503 and the rear clamping plate 504 are located on the lifting plate 507 and can move back and forth. The front clamping plate 503 and the rear clamping plate 504 move synchronously and in opposite directions.

[0040] A telescopic mechanism 506 is provided between the placement rack 501 and the lifting plate 507. The telescopic mechanism 506 drives the lifting plate 507 to move up and down relative to the placement rack 501. A gear 511 is rotatably mounted on the lifting plate 507. The front clamping plate 503 and the rear clamping plate 504 are slidably connected to the lifting plate 507, allowing them to move back and forth relative to each other. An upper rack 510 is fixedly mounted on the front clamping plate 503, and a lower rack 512 is fixedly mounted on the rear clamping plate 504. The upper rack 510 meshes with the upper part of the gear 511, and the lower rack 512 meshes with the lower part of the gear 511. A second telescopic mechanism 508 is provided on the lifting plate 507, which drives the rear clamping plate 504 to move back and forth. The lifting plate 507 is rotatably equipped with an upper pressure roller 509 and a lower pressure roller 513. The upper pressure roller 509 is in contact with the upper surface of the upper rack 510, and the lower pressure roller 513 is in contact with the lower surface of the lower rack 512. A housing 502 is provided on the left side of the lifting plate 507. The housing 502 covers the gear 511, the upper rack 510, the lower rack 512 and other structures in the space between the housing 502 and the lifting plate 507.

[0041] The profile is placed on multiple material support mechanisms 5, which move synchronously. Multiple rollers 505 move upwards to support and lift the profile. Simultaneously, the front clamping plate 503 and the rear clamping plate 504 move synchronously towards the center to clamp and position the profile. This simultaneous movement of the front and rear clamping plates 503 and 504 towards the center moves the profile towards the center position. The synchronous cooperation of the multiple material support mechanisms 5 ensures the profile is placed horizontally and moves it vertically. Once the profile is moved to a designated height, the rear clamping mechanism 3 moves left and right along the support frame 1 to the left end of the tube / profile, where it is clamped. After clamping, the front and rear clamping plates 503 and 504 release the profile. The bottom rollers 505, in conjunction with the rear clamping mechanism 3, move the tube / profile left and right, providing bottom support and preventing deformation due to gravity.

[0042] That is, by controlling the telescopic mechanism 506 to drive the lifting plate 507 to move up and down, the roller 505 will move upward to lift the bottom of the profile. At the same time, the telescopic mechanism 508 will drive the rear clamping plate 504 to move forward, which will drive the lower rack 512 to move forward. The lower rack 512 will drive the gear 511 to rotate, which will drive the upper rack 510 to rotate, which will drive the front clamping plate 503 to move backward in sync. Then the front clamping plate 503 and the rear clamping plate 504 will limit and clamp the profile. The upper pressure roller 509 and the lower pressure roller 513 are provided to work with the gear 511 to limit the upper rack 510 and the lower rack 512 respectively, preventing the upper rack 510 and the lower rack 512 from moving up and down and disengaging from the gear 511. The upper pressure roller 509 and the lower pressure roller 513 are both rotatably connected to the lifting plate 507. Therefore, when the upper rack 510 and the lower rack 512 move back and forth, the friction between them can be reduced and the noise generated can be reduced.

[0043] Example 3: A drive mechanism is provided between the support frame 1 and the rear clamping mechanism 3. The drive mechanism drives the rear clamping mechanism 3 to move left and right along the support frame 1. The drive mechanism only needs to be able to drive the rear clamping mechanism 3 to move left and right along the support frame 1, and there is no technical limitation; it is existing technology. The rear clamping mechanism 3 is existing technology that can fix and clamp the pipe or profile and release it, and there is no technical description.

[0044] Example 4: The central clamping mechanism 7 is mounted on the support frame 1 and moves left and right along the support frame 1. A second driving mechanism is provided between the central clamping mechanism 7 and the support frame 1, which drives the central clamping mechanism 7 to move left and right along the support frame 1. The ability of the second driving mechanism to move the central clamping mechanism 7 left and right along the support frame 1 is not a technical limitation and is considered existing technology. The central clamping mechanism 7 is existing technology capable of clamping and releasing pipes and profiles; further technical details are not provided.

[0045] Example 5: Figure 6-10 As shown, the end-feeding mechanism 6 includes a bracket 601. A feeding plate 602 is rotatably mounted on the front side of the bracket 601. A movable frame 604 is mounted on the upper side of the bracket 601, and the movable frame 604 is located on the bracket 601 and can move left and right. A side clamping mechanism 2 is mounted on the movable frame 604. The side clamping mechanism 2 includes a rear clamp 610 and a front clamp 612. Both the rear clamp 610 and the front clamp 612 are located on the movable frame 604 and can move back and forth. The rear clamp 610 and the front clamp 612 are symmetrically distributed and move synchronously in opposite directions. The side clamping mechanism 2 clamps the profile from both the front and rear sides, facilitating subsequent cutting operations.

[0046] A telescopic mechanism 605 is fixedly installed on the movable frame 604. The telescopic mechanism 605 drives the side clamping mechanism 2 to clamp the profile. The output end of the telescopic mechanism 605 is fixedly connected to the rear clamp 610. A gear 613 is rotatably installed on the movable frame 604. An upper rack 614 and a lower rack 611 are respectively installed at the upper and lower ends of the gear 613. The upper rack 614 and the lower rack 611 are both movable back and forth on the movable frame 604. The upper rack 614 and the lower rack 611 mesh with the gear 613. The upper rack 614 is fixedly connected to the front clamp 612, and the lower rack 611 is fixedly connected to the rear clamp 610. The clamping force of the front clamp 612 and the rear clamp 610 on the profile can be controlled by the air pressure of the air supply source of the telescopic mechanism 605 (cylinder).

[0047] A drive mechanism 606 is installed on the movable frame 604. The drive mechanism 606 drives the movable frame 604 to move left and right along the support 601. The drive mechanism 606 is fixed on the movable frame 604. A movable rack 609 is installed on the movable frame 604. A movable gear 511 is installed at the output end of the drive mechanism 606. The movable gear 511 meshes with the movable rack 609. The drive mechanism 606 drives the movable gear 511 to rotate. Through the meshing action of the movable rack 609, the movable frame 604 moves left and right along the support 601.

[0048] The rear end of the blanking plate 602 is rotatably connected to the support 601. A cylinder 603 is installed between the blanking plate 602 and the support 601, with its upper and lower ends rotatably connected to the blanking plate 602 and the support 601, respectively. There are at least two blanking plates 602 horizontally distributed, and a material-blocking mechanism is installed between adjacent blanking plates 602. The material-blocking mechanism is rotatably connected to the support 601. The material-stopping mechanism includes a material-stopping plate 608. The rear end of the material-stopping plate 608 is rotatably connected to the support 601. A second cylinder 607 is rotatably connected to the lower front end of the material-stopping plate 608. The lower end of the second cylinder 607 is rotatably connected to the support 601. The material-stopping plate 608 is used in special circumstances. That is, after the tubular profile is released from the clamping mechanism, in order to prevent it from rolling on the dropping plate 602, the second cylinder 607 drives the material-stopping plate 608 to rotate upward. The front end of the material-stopping plate 608 protrudes upward from the dropping plate 602, which can prevent the tubular profile from rolling off the dropping plate 602. Rollers are rotatably provided at both ends of the dropping plate 602. The profile can directly contact the rollers, which can facilitate the movement of the profile and reduce the friction between the profile and the device.

[0049] When this application is in use, when the pipe or profile moves from left to right onto the blanking plate 602, the side clamping mechanism 2 clamps the left and right sides of the profile. Specifically, the telescopic mechanism 605 on the side clamping mechanism 2 drives the rear clamp 610 to move forward, and at the same time, the upper rack 614, lower rack 611, gear 613 and other structures drive the front clamp 612 to move backward, thereby realizing that the rear clamp 610 and the front clamp 612 move towards the middle synchronously to clamp and position the profile. Then, the drive mechanism 606 is controlled to rotate, and the interaction of the moving rack 609 and the moving gear 511 drives the moving frame 604 to move left and right, thereby realizing the left and right movement of the profile.

[0050] After the profile is cut, the side clamping mechanism 2 is reset to release the clamping force on the profile; then, by controlling the cylinder 603 to retract, the blanking plate 602 is driven to rotate downward, thereby flipping the profile on the blanking plate 602 off, and the profile falls down along the blanking plate 602 under its own weight.

[0051] This embodiment achieves integrated control of clamping, movement, and unloading in the end-of-line material unloading mechanism by incorporating a rotatable unloading plate, a movable frame with a side clamping mechanism, and a dual-cylinder linkage material-stopping mechanism. The side clamping mechanism, through a synchronous meshing drive structure of upper and lower racks and gears, enables the front and rear clamps to simultaneously clamp the left and right sides of the profile, with uniform and adjustable clamping force, ensuring the stability and accuracy of the end-of-line cutting.

[0052] The drive mechanism three, in conjunction with the moving rack and pinion, enables the lateral movement of the side clamping mechanism, making the feeding and alignment of the end workpiece more precise and efficient. The set-in unloading plate can be automatically flipped by cylinder one, smoothly unloading the cut profile and reducing manual intervention. The safety protection mechanism composed of the baffle plate and cylinder two prevents the tubular profile from rolling off after being released from clamping, significantly improving operational safety and reliability. With the support of rollers, the profile movement resistance is low, reducing friction, wear, and surface scratches, further optimizing the user experience and service life of the equipment. This embodiment features a coordinated structure and smooth operation, enabling synchronized control of the entire process of automatic end cutting and unloading, improving the automation level and production efficiency of the equipment.

[0053] It should be noted that the cutting machine, drive mechanism (including drive mechanism one, drive mechanism two, and drive mechanism three), telescopic mechanism (including telescopic mechanism one, telescopic mechanism two, and telescopic mechanism three), lifting plate, roller, cylinder, gear meshing transmission, limit and guide mechanism, as well as the electrical system, PLC control logic, and signal feedback system controlling them involved in the embodiments of this application, can all be implemented using existing mature technologies. Their structural form, drive method, and control logic do not constitute the focus of innovation in this application, and therefore will not be described in detail. Those skilled in the art can select conventional drive components such as pneumatic, hydraulic, electric, servo, or stepper motors to realize the telescopic, lifting, clamping, rotating, and resetting actions of each mechanism according to actual needs. They can also use existing electrical control systems, automation programs, or sensor detection modules to monitor and coordinate the operation status of the device, all of which fall within the scope of equivalent substitution in this application.

For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
