Description

Technical Field

[0001] This utility model relates to the field of pipe and profile cutting technology, and in particular to an end-feeding device for pipe and profile cutting. Background Technology

[0002] Currently, clamping and positioning are typically required to ensure cutting accuracy during the cutting process of pipes and profiles. However, most existing devices use single-sided clamping or manual-assisted positioning, which results in insufficient clamping stability and easily causes the pipes and profiles to shake during cutting. This not only affects the cutting quality but may also cause the workpiece to be scrapped.

[0003] After cutting, pipes and profiles typically need to be unloaded. Existing equipment generally relies on manual handling or simple sliding methods for unloading, resulting in a low level of automation. For longer profiles, manual unloading is not only time-consuming and labor-intensive but also poses certain safety risks, making it difficult to meet the needs of efficient and continuous production.

[0004] Although some improved equipment has incorporated rollers or slide rails on the worktable to reduce friction between the profile and the device and facilitate movement, these devices often lack a positioning design that links with the clamping mechanism, making the profile prone to shifting during movement or cutting. Furthermore, while some equipment is equipped with a flip-plate unloading structure, its simple design fails to effectively prevent round tubular workpieces from rolling off after flipping, posing a safety hazard.

[0005] In summary, existing technologies still have shortcomings in terms of stable clamping, automatic movement, and safe unloading of profiles, making it difficult to guarantee operational safety. The technical problem this invention aims to solve is to provide a reasonably structured and easy-to-operate end-feeding device for pipe and profile cutting, enabling reliable clamping, precise movement, and safe unloading of profiles, thereby improving production efficiency. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an end-feeding device for cutting pipes and profiles.

[0007] The purpose of this utility model is achieved as follows: A cutting end blanking device for pipes and profiles includes a support frame. A blanking plate is rotatably mounted on the front side of the support frame. A movable frame is mounted on the upper side of the support frame and can move left and right. A clamping mechanism is mounted on the movable frame, including a rear clamp and a front clamp. Both the rear and front clamps are movable forward and backward on the movable frame, symmetrically distributed, and move synchronously in opposite directions. The clamping mechanism clamps the profile from both the front and rear sides.

[0008] A telescopic mechanism is fixedly installed on the movable frame, which drives the clamping mechanism to clamp the profile. The output end of the telescopic mechanism is fixedly connected to the rear clamp. A gear is rotatably installed on the movable frame, with an upper rack and a lower rack at each end of the gear. Both the upper and lower racks are located on the movable frame and can move back and forth. The upper and lower racks mesh with the gear. The upper rack is fixedly connected to the front clamp, and the lower rack is fixedly connected to the rear clamp.

[0009] When this application is in use, when the pipe or profile moves from left to right onto the blanking plate, the clamping mechanism clamps the left and right sides of the profile (relative to the left and right sides of the profile, and to the front and rear sides of this device). That is, the telescopic mechanism on the clamping mechanism drives the rear clamp to move forward, and at the same time, the upper rack, lower rack, gear and other structures drive the front clamp to move backward, thereby realizing that the rear clamp and the front clamp move towards the middle synchronously to clamp and position the profile; then control the drive mechanism to rotate, and through the interaction of the moving rack and moving gear, drive the moving frame to move left and right, thereby realizing the left and right movement of the profile.

[0010] After the profile is cut, the clamping mechanism is reset to release the clamping force on the profile. Then, by controlling the cylinder to retract, the blanking plate is rotated downwards, causing the profile on the blanking plate to fall off. The profile falls downwards along the blanking plate under its own weight. This application achieves the movement of the profile by eliminating the need for the blanking plate to move with the clamping mechanism when clamping and moving it left and right. Traditional cutting equipment requires a certain amount of space to be reserved at the rear of the blanking plate for the clamping mechanism to move the profile left and right. This application eliminates this space requirement, resulting in a simpler equipment structure and reduced space occupation.

[0011] Beneficial effects: This utility model has the following technical effects when used:

[0012] 1. This device, by setting up a front clamp and a rear clamp, and combining the linkage structure of the upper rack, lower rack and gear, can realize the synchronous movement of the front and rear clamps towards the middle, reliably clamping both sides of the pipe or profile, ensuring the stability of the profile during the cutting process, and avoiding the impact of profile shaking on the cutting accuracy.

[0013] 2. The telescopic mechanism drives the clamping action, and clamping and releasing can be completed automatically, reducing the tediousness of manual adjustment, improving operating efficiency, and also reducing the labor intensity of workers.

[0014] 3. The movable frame moves left and right by driving the movable rack and gear through the drive mechanism, which can flexibly adjust the position of the profile on the support frame, facilitate subsequent cutting and positioning, and improve the applicability and ease of operation of the device.

[0015] 4. The blanking plate can be flipped by a cylinder. After cutting, the profile can be automatically flipped down and unloaded by its own weight, avoiding manual handling, reducing labor costs and improving production continuity.

[0016] 5. A baffle mechanism is installed between the blanking plates. In special circumstances, the baffle plate can be driven upward by cylinder two to effectively prevent tubular profiles from rolling off the blanking plates, thus improving the safety and reliability of the device. The main purpose is to prevent some profiles from moving uncontrollably along the front-to-back direction of the support frame when the clamping mechanism is not clamped, and to prevent round profiles from rolling off the flip plate.

[0017] 6. Rollers are installed at both ends of the blanking plate to allow the profile to roll smoothly on the blanking plate, which reduces friction loss, facilitates profile movement, and improves the smoothness of conveying and positioning.

[0018] 7. The overall structure is reasonably designed, integrating clamping, moving, cutting positioning and automatic unloading functions. It has the advantages of high automation, simple operation and high efficiency, and can be widely used in the cutting and processing of pipes and profiles. Attached Figure Description

[0026] Example 1, such as Figure 1-5As shown, the present invention provides an end-feeding device for cutting pipes and profiles, comprising a support frame 1. A feeding plate 2 is rotatably mounted on the front side of the support frame 1. A movable frame 4 is mounted on the upper side of the support frame 1, and the movable frame 4 is movable left and right on the support frame 1. A clamping mechanism is mounted on the movable frame 4, comprising a rear clamp 10 and a front clamp 12. Both the rear clamp 10 and the front clamp 12 are symmetrically distributed and move synchronously in opposite directions on the movable frame 4. The clamping mechanism clamps the profile from both the front and rear sides, facilitating subsequent cutting operations.

[0027] A telescopic mechanism 5 is fixedly installed on the movable frame 4. The telescopic mechanism 5 drives the clamping mechanism to clamp the profile. The output end of the telescopic mechanism 5 is fixedly connected to the rear clamp 10. A gear 13 is rotatably installed on the movable frame 4. An upper rack 14 and a lower rack 11 are respectively installed at the upper and lower ends of the gear 13. The upper rack 14 and the lower rack 11 are located on the movable frame 4 and can move back and forth. The upper rack 14 and the lower rack 11 mesh with the gear 13. The upper rack 14 is fixedly connected to the front clamp 12, and the lower rack 11 is fixedly connected to the rear clamp 10. The squeezing and clamping force of the front clamp 12 and the rear clamp 10 on the profile can be controlled by the air pressure of the air supply source of the telescopic mechanism 5 (cylinder).

[0028] A drive mechanism 6 is provided on the movable frame 4, which drives the movable frame 4 to move left and right along the support frame 1. The drive mechanism 6 is fixed on the movable frame 4, and a movable rack 9 is provided on the movable frame 4. A movable gear 13 is provided at the output end of the drive mechanism 6. The movable gear 13 meshes with the movable rack 9. The drive mechanism 6 drives the movable gear 13 to rotate, and through the meshing action of the movable rack 9, the movable frame 4 moves left and right along the support frame 1.

[0029] The rear end of the blanking plate 2 is rotatably connected to the support frame 1. A cylinder 3 is installed between the blanking plate 2 and the support frame 1, with its upper and lower ends rotatably connected to the blanking plate 2 and the support frame 1, respectively. There are at least two blanking plates 2 horizontally distributed, and a baffle mechanism is installed between adjacent blanking plates 2. The baffle mechanism is rotatably connected to the support frame 1. The baffle mechanism includes a baffle plate 8, the rear end of which is rotatably connected to the support frame 1. A cylinder 7 is rotatably connected to the lower front end of the baffle plate 8, and the lower end of the cylinder 7 is rotatably connected to the support frame 1. The baffle plate 8 is used in special circumstances. That is, if the tubular profile is released from its clamping mechanism, in order to prevent it from rolling on the blanking plate 2, the cylinder 7 drives the baffle plate 8 to rotate upward. The front end of the baffle plate 8 protrudes upward from the blanking plate 2, which can prevent the tubular profile from rolling off the blanking plate 2. The blanking plate 2 is equipped with rotatable rollers at both ends. The profile can be directly attached to the rollers, which can facilitate the movement of the profile and reduce the friction between the profile and the device.

[0030] When this application is in use, when the pipe or profile moves from left to right onto the blanking plate 2, the clamping mechanism clamps the left and right sides of the profile. Specifically, the telescopic mechanism 5 on the clamping mechanism drives the rear clamp 10 to move forward, and at the same time, the upper rack 14, lower rack 11, gear 13 and other structures drive the front clamp 12 to move backward, thereby realizing that the rear clamp 10 and the front clamp 12 move towards the middle synchronously to clamp and position the profile. Then, the drive mechanism 6 is controlled to rotate, and the interaction of the moving rack 9 and the moving gear 13 drives the moving frame 4 to move left and right, thereby realizing the left and right movement of the profile.

[0031] After the profile is cut, the clamping mechanism is reset to release the clamping force on the profile; then, by controlling the cylinder 3 to retract, the blanking plate 2 is driven to rotate downward, thereby flipping the profile on the blanking plate 2 off. The profile falls downward along the blanking plate 2 under its own weight.

[0032] In the above technical solution, the telescopic mechanism 5, the drive mechanism 6, the cylinder 3, and the cylinder 7 are operated by a controller. The controller and the control method are existing technologies and can achieve the functions required by this application. There are no technical restrictions on the specific setting position or method.
