Description

Technical Field

[0001] This utility model relates to the field of metal sheet stamping production technology, and in particular to a stamping tail material conveyor. Background Technology

[0002] In the field of sheet metal stamping production, automated stamping production lines have been widely used. These production lines typically use large robotic arms or feeding mechanisms to pick up sheet metal from stacks and sequentially feed it into stamping presses of different tonnages for continuous stamping and forming.

[0003] However, in actual production, existing feeding mechanisms suffer from a significant technical bottleneck. Due to structural limitations of the robotic gripper and considerations for safe spacing between equipment, there is an insurmountable "dead zone" between the end of the feeding mechanism's stroke and the center of the die when delivering sheet metal into the stamping die. This results in a 4-6 meter long tail of sheet metal at the end of each sheet that cannot be accurately delivered to the effective stamping station of the die for processing. This unusable tail of sheet metal is directly cut off and discarded as scrap at the end of the production line, causing a huge waste of raw materials.

[0004] For the production of large stamped parts or the processing of precious metal sheets, the accumulation of this continuous, fixed-length waste of tailings can lead to a significant increase in production costs and seriously affect the economic efficiency of production. Currently, the industry lacks specialized equipment that can effectively collect and reuse this "tailing."

[0005] Therefore, there is an urgent need to design a device that can seamlessly interface with the end of existing automated stamping lines, specifically designed to clamp and transport this long tail of material, in order to recover this valuable portion of material, reduce production costs, and improve material utilization. Clearly, existing technologies still require improvement and enhancement. Summary of the Invention

[0008] In one embodiment of the present invention, a drive cylinder is further included; the cylinder body of the drive cylinder is fixedly connected to the mounting base, and the end of its piston rod is fixedly connected to the operating table, wherein the operating table is driven by the extension and retraction of the drive cylinder and slides along the slide rail.

[0019] This utility model provides a stamping tail material conveyor. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. In the description of this utility model, it should be understood that the terms "up, down, left, right," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and should not be construed as limiting this utility model; in addition, the terms "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] Please see Figure 1 and Figure 2 This utility model provides a stamping tail material conveyor, including a mounting base 1 and a sheet material conveying assembly. The top surface of the mounting base 1 is provided with a slide rail 2. The sheet material conveying assembly includes an operating platform 3, an upper roller 4, and a lower roller 5. The operating platform 3 is slidably mounted on the slide rail 2, and the lower roller 5 is fixedly mounted on the operating platform 3. The upper roller 4 is suspended directly above the lower roller 5 by a lifting cylinder 6. The stamping tail material can be clamped between the upper roller 4 and the lower roller 5, forming a conveying mechanism. During operation, the lifting cylinder 6 drives the upper roller 4 to move vertically up and down, thereby coordinating with the fixed lower roller 5 to firmly clamp the stamped tail material between them. By driving the rollers to rotate, friction can be used to achieve continuous and stable conveying of the tail material.

[0021] To automate the movement of the sheet metal conveying assembly, a drive cylinder 7 is added to this equipment. The cylinder body of the drive cylinder 7 is directly connected to the upper end of the mounting base 1 via a fixed bracket. The piston rod end of the drive cylinder 7 is fixed to the corresponding part of the operating table 3 via a spherical bearing or a connector. When compressed air is introduced into the drive cylinder 7, the extension or retraction of its piston rod is directly converted into a pushing or pulling force on the operating table 3, thereby driving the entire sheet metal conveying assembly to slide precisely and smoothly back and forth along the slide rail 2 to adapt to different feeding position requirements.

[0022] To ensure that the sheet material tailings can smoothly and accurately enter between the rollers, a sheet material guiding assembly is fixedly installed on the operating platform 3, on the side of the lower roller 5 facing the discharge direction. The sheet material guiding assembly mainly consists of a guide frame 8 and guide wheels 9. The guide frame 8 is a steel structure, firmly installed on the operating platform 3. Multiple guide wheels 9 are installed side-by-side and spaced apart on the guide frame 8 along the expected conveying path of the sheet material. All guide wheels 9 can rotate freely, and the channel they form is adapted to the width and entry angle of the sheet material tailings, providing initial guidance and correction of the sheet material, preventing it from deviating or getting stuck.

[0023] The guide frame 8 is installed at a height lower than the axis of the lower roller 5, allowing the guide wheel 9 to provide bottom-bearing guidance for the tail material. When the tail material enters the guide assembly, its lower surface contacts the rim of the guide wheel 9, and the guide wheel 9 provides upward support, achieving "bottom-bearing guidance." This structure prevents the tail material from deviating from the conveying path due to its own weight, and is especially suitable for the initial guidance of longer tail materials, ensuring a smooth transition to the upper surface of the lower roller 5. To avoid scratching the surface of the sheet material, the guide wheel 9 is made of non-metallic materials with moderate elasticity and wear resistance, such as rubber. The outer circumference of the guide wheel 9 is machined into a smooth arc surface without sharp edges; on the one hand, it can produce flexible rolling contact with the surface of the sheet material, minimizing scratches or indentations; on the other hand, the smooth arc surface helps the sheet material slide smoothly into the correct position when contacting the guide wheel 9, reducing frictional resistance.

[0024] A drive motor 10 is fixedly mounted on the operating platform 3. The output shaft of the drive motor 10 is connected to the rotating shaft of the lower roller 5 via a transmission chain 11 to drive the lower roller 5 to rotate and cooperate with the upper roller 4 to convey the tail material of the sheet metal. Specifically, a drive sprocket is mounted on the output shaft of the drive motor 10, and a driven sprocket is mounted on the end of the rotating shaft of the lower roller 5. The transmission chain 11 is fitted on the drive sprocket and the driven sprocket and maintains appropriate tension. When the drive motor 10 starts, power is transmitted to the lower roller 5 through the chain transmission system, driving it to rotate. The sheet metal, pressed against the rotating lower roller 5 by the lifting cylinder 6, is then conveyed out together with the upper roller 4 under the action of friction.

[0025] The mounting base 1 has an internal mounting cavity, within which a pneumatic system 12 is integrated. The pneumatic system 12 is connected to the lifting cylinder 6 and the drive cylinder 7 via air circuits. Optionally, the pneumatic system 12 includes a filter, a pressure reducing valve, an oil mist lubricator, an electromagnetic control valve assembly, and connecting pipelines. The pneumatic system 12 is connected via internal pipelines to the lifting cylinder 6, which controls the lifting of the upper roller 4, and the drive cylinder 7, which drives the movement of the operating table 3, providing a clean, stable, and centrally controlled power source for all pneumatic actuators.

[0026] To enable rapid, flexible, and stable installation of the equipment on the production line, multiple support feet 13 are evenly spaced along the perimeter of the mounting base 1. Each support foot 13 is a detachable suction cup structure. Each support foot 13 is screwed into a threaded hole at the bottom of the mounting base 1 via a threaded rod at its top, or is detachably fixed to the base via a quick-release snap-fit ​​mechanism. The suction cup structure of the support feet 13 allows them to firmly adhere to smooth surfaces, providing sufficient support and stability, while eliminating the need for drilling into the ground, facilitating equipment repositioning and maintenance.

[0027] In summary, the stamping tail material conveyor of this invention, through a sheet metal conveying assembly that can slide to the end of the stamping line, can instantly clamp and receive long sections of sheet metal tail material that cannot be utilized by conventional feeding mechanisms during the stamping production gap, under the synergistic action of the upper roller 4 and the lower roller 5. Subsequently, the entire device can move smoothly along the slide rail 2, and by utilizing the continuous rotation of the rollers, the tail material that was previously forced to be discarded is re- and stably conveyed to the subsequent workstation or recycling area. This process achieves seamless capture and transfer of valuable raw materials, transforming the originally fixed length of waste into materials that can be continuously utilized, thereby significantly improving the utilization rate of raw materials and effectively reducing production costs. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0028] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
