Description

Technical Field

[0001] This invention belongs to the technical field of sheet material folding processing equipment, and specifically discloses a thin workpiece folding mechanism with follow-up roller pressing function. Background Technology

[0002] During the folding process of thin sheet materials, after the sheet is folded and formed, the folded edge is prone to springback and warping. This is especially true for thin sheet materials with softer textures, which lack the follow-up clamping constraint after forming, making it difficult to guarantee the quality of product processing. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a thin workpiece folding mechanism with a follow-up roller clamping function. This invention adds an independent follow-up roller clamping structure, which can automatically clamp and shape the folded edge after the thin sheet material is folded and formed. The entire clamping structure can move synchronously with the rotary station, continuously applying follow-up pressure to the folded edge of the workpiece throughout the entire rotation and repositioning process, effectively suppressing the springback and warping of the thin sheet, and significantly improving the folding accuracy and processing stability of the thin sheet.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a thin workpiece folding mechanism with follower roller pressing function, comprising an adsorption plate (1), an adsorption plate swing rod (2), an adsorption plate U-shaped support (3), a follower roller (4), a follower swing rod (5), a roller horizontal U-shaped support (6), a rotary table (7), a rotary table motor (8), a base (9), a pressing roller motor (10), and an adsorption plate swing motor (11).

[0017] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The present invention includes an adsorption plate (1), an adsorption plate swing rod (2), an adsorption plate U-shaped support (3), a follower roller (4), a follower swing rod (5), a roller horizontal U-shaped support (6), a rotary table (7), a rotary table motor (8), a base (9), a pressing roller motor (10), and an adsorption plate swing motor (11).

[0018] The adsorption plate (1) is the material adsorption and bearing component. The adsorption plate swing arm (2) connects the adsorption plate (1) and the adsorption plate U-shaped support (3). The adsorption plate U-shaped support (3) is fixedly installed above the base (9) with its opening facing upward. The adsorption plate swing motor (11) is assembled on the outside of the adsorption plate U-shaped support (3). The output shaft of the adsorption plate swing motor (11) passes through the bearing hole of the support and drives the adsorption plate swing arm (2) to swing, thereby driving the adsorption plate (1) to complete a nearly 180-degree coaxial flipping action of the material.

[0019] The horizontal U-shaped support (6) for rollers is a horizontally arranged support component. The horizontal U-shaped support (6) for rollers is located outside the U-shaped support (3) for adsorption plates. The follower swing arm (5) is hinged to the upper part of the horizontal U-shaped support (6) for rollers. The follower roller (4) is rotatably installed at the end of the follower swing arm (5). The clamping roller motor (10) is fixedly installed on the side of the horizontal U-shaped support (6) for rollers, providing swing power to the follower swing arm (5) and driving the follower roller (4) to complete the clamping action and the reset and avoidance action.

[0020] The rotary table (7) is assembled and installed on the upper surface of the base (9). The rotary table (7) can rotate 90 degrees in the horizontal plane. The adsorption plate U-shaped support (3) and the roller horizontal U-shaped support (6) are fixed as a whole on the upper surface of the rotary table (7). When the rotary table (7) is working, it can drive all the upper folding components and pressing components to rotate and reposition synchronously, making room for subsequent processing steps.

[0021] The workflow of this device is as follows. In the initial state of the equipment, both the adsorption plate (1) and the follower roller (4) are in the standby initial position. During processing, the adsorption plate (1) adsorbs and fixes the thin workpiece. The adsorption plate swing motor (11) starts, driving the adsorption plate (1) to complete the 180-degree coaxial folding and forming of the workpiece. After the folding action is completed, the pressing roller motor (10) drives the follower swing arm (5) to swing, so that the follower roller (4) fits against the folded edge of the workpiece.

[0022] After the clamping and positioning are completed, the rotary table motor (8) drives the rotary table (7) to rotate horizontally by 90 degrees. Throughout the rotation, the follower roller (4) remains in a close and clamping state, continuously following and re-pressing the edge of the newly formed sheet to fix it. After the station rotation and positioning are completed, it waits for the subsequent process. After the subsequent process is completed, the entire mechanism rotates in the opposite direction to reset, the follower roller (4) is lifted to avoid it, and it enters the next round of processing standby state.

[0023] It should be noted that the follow-up roller (4) adopts a time-following operation logic. The roller is only pressed down into place after the adsorption plate (1) has completed the workpiece folding and forming. The roller pressing action is time-matched with the station rotation action, which can suppress the springback deformation of the soft sheet edge throughout the process.

[0024] Beneficial effects

[0025] This invention adds an independent follow-up roller clamping component to the traditional coaxial folding mechanism. It allows for immediate clamping and shaping of thin sheet materials after folding. The clamping structure follows the rotation of the workstation to maintain pressure throughout the entire process. This effectively solves the industry pain point of springback and warping during the folding of soft, thin sheets. This invention offers high forming precision, good processing stability, strong structural linkage, and is suitable for automated folding production lines for various thin, soft materials, making it widely applicable.

[0026] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any simple modifications and equivalent substitutions made based on the technical concept of the present invention are within the protection scope of the present invention.
