Description

Technical Field

[0001] This utility model relates to the field of bending, specifically to a novel front feed rack for a bending machine. Background Technology

[0002] A bending machine is a machine that can bend thin sheets of paper. In early bending operations, manual positioning of the sheet metal was the primary method. To address this issue, a front material rack for bending machines was introduced to provide auxiliary support and temporarily store raw materials before processing. This not only effectively reduced labor intensity but also significantly improved production efficiency.

[0003] The existing front material rack for bending machines, as disclosed in patent number CN202322366746.1, is a heavy-duty liftable front material support for bending machines. However, this front material rack is not conducive to the positioning of sheet metal and requires manual experience for processing. This not only easily leads to dimensional deviations in the bent workpiece due to operational errors but also increases the learning cost. Therefore, this utility model proposes a novel front material rack for bending machines. Summary of the Invention

[0005] The purpose of this utility model is achieved through the following means: a novel front material rack for a bending machine, comprising a feeding structure and a lifting structure, wherein a movable limiting block is installed at one end of the feeding structure via a guide rail structure, the limiting block is rotatably mounted on the guide rail structure, a positioning plane is provided on the limiting block, and the lower end of the limiting block is fixedly engaged with the guide rail structure by screws.

[0006] Furthermore, the lifting structure includes a base and a scissor frame mounted on the base. The scissor frame is connected to the feeding structure, and a hydraulic cylinder is provided inside the scissor frame to drive the scissor frame to fold and lift.

[0007] Furthermore, the lower end of the base is provided with support legs and casters, and the support legs are mounted on the lower end of the base in a height-adjustable manner.

[0008] Furthermore, the feeding structure includes a feeding rail and several rollers, with the rollers installed side by side inside the feeding rail.

[0009] Furthermore, the feeding rail is provided with a plurality of slots, the upper end of the slots extends upward and penetrates the feeding rail, and the roller is installed in the slots.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] In this embodiment, refer to Figures 1-4 This invention relates to a novel front feeder for a bending machine, comprising a feeding structure and a lifting structure. Two feeding structures and two lifting structures are provided for each. A limit block 4 is mounted on one side of the feeding structure via a guide rail structure 2. The guide rail design allows the limit block 4 to move along the guide rail structure 2 and is fixed with screws, thereby achieving the effect of adjusting and fixing its position. This allows the limit block 4 to better adapt to plates of different sizes. The limit block 4 has a positioning plane 9, which allows the operator to position the workpiece close to the positioning plane 9, ensuring the stability and accuracy of the feeding process. This prevents the workpiece from shifting or misaligning during feeding, thus affecting the subsequent bending processing accuracy.

[0020] Furthermore, a turntable 6 is provided at the lower end of the limiting block 4. The turntable 6 is connected to the guide rail structure 2, allowing the limiting block 4 to be rotated and adjusted. It is also fixed to the guide rail structure 2 with screws. The turntable 6 allows the operator to adjust the angle of the limiting block 4 according to actual needs and tighten the screws to secure the limiting block 4, ensuring its stability. This adapts to different angles of sheet metal, significantly improving the flexibility and adaptability of the front material rack. In addition, the outer circumference of the turntable 6 is engraved with scale lines 8. By observing these scale lines 8, the operator can more precisely adjust the angle of the limiting block 4, further improving positioning accuracy and operational efficiency.

[0021] Furthermore, the lifting structure includes a base 3 and a scissor frame 5 mounted on the base 3. The scissor frame 5 is connected to the feeding structure, and a hydraulic cylinder 7 is installed within the scissor frame 5 to drive its folding and lifting. The structure of the scissor frame 5 allows the feeding structure to move smoothly and precisely in the vertical direction. The operator can adjust the height of the feeding structure according to actual needs to ensure that the workpiece can be accurately fed into the bending area. Therefore, this structure is suitable for various models and different heights of bending machines, and the driving method of the hydraulic cylinder 7 makes the lifting operation simpler and faster. The height of the feeding structure can be adjusted simply by controlling the extension and retraction of the hydraulic cylinder 7, improving the convenience and efficiency of operation.

[0022] Furthermore, the lower end of the base 3 is equipped with casters 11 and adjustable feet 10. The casters 11 facilitate the movement of the entire front material rack, allowing it to be easily moved when not in use, thus avoiding disruption to the production process. The adjustable feet 10 effectively prevent movement during use, ensuring the stability and safety of the equipment. The operator can adjust the height of the feet 10 according to the actual working environment and ground flatness to keep the front material rack level, thereby avoiding feeding errors caused by tilting or swaying. This design makes the front material rack easy and flexible to move when needed, and stable and reliable when fixed, balancing flexibility and stability.

[0023] Furthermore, the upper end of the feeding rail 1 is provided with several slots 12. The design of the slots 12 extending upward and penetrating through the receiving rail makes it easier to assemble and disassemble the rollers 13 installed in the slots 12. When a roller 13 malfunctions or is damaged, the damaged roller 13 can be directly removed for replacement or repair, thereby effectively saving maintenance time and costs, and facilitating the replacement of vulnerable parts.

[0024] The roller 13 is preferably made of plastic or a material with excellent cushioning properties to prevent the workpiece from being scratched. The surface of the roller 13 is smooth, and the rolling friction has less resistance than the sliding friction, making it easier for the operator to push the workpiece, thereby significantly improving the smoothness and efficiency of feeding.

[0025] The beneficial effects of this invention are as follows: By installing a limiting block 4 that can slide along the guide rail structure 2 at one end of the feeding structure, it is possible to accurately position plates of different specifications, thus adapting to plates of various sizes. Furthermore, the rotatable design of the limiting block 4 allows the positioning plane 9 to be flexibly adjusted in angle. Even when the operator is facing a plate with an angle, they can achieve a perfect fit with the plate by adjusting the angle of the positioning plane 9. This not only further enhances compatibility with plates of different sizes but also significantly improves the adaptability and flexibility of the front feeder, effectively avoiding the problem of frequent machine downtime for adjustments when changing plates.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
