Description

Technical Field

[0001] This utility model belongs to the field of bending machine technology, specifically relating to an auxiliary support for workpiece positioning at the rear of a bending machine. Background Technology

[0002] Bending machines are commonly used equipment in sheet metal processing. During the bending process, a rear positioning stop is typically used to position the workpiece. However, when the portion of the workpiece extending beyond the bending line is long and the workpiece itself is thin, it is prone to deformation under its own weight or external forces, leading to inaccurate positioning. In this case, traditional positioning stops not only fail to effectively restrict the workpiece position but may also exacerbate workpiece deformation, affecting the dimensional accuracy of the bending process and reducing product yield and production efficiency.

[0003] Therefore, existing technologies suffer from the technical problem of lacking effective auxiliary support and positioning for thin-walled long workpieces during bending. There is an urgent need for a device that can adapt to different workpiece angles, provide stable support, and assist in positioning. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary bracket for positioning workpieces after bending machine, so as to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A workpiece positioning auxiliary bracket for a bending machine includes: a mounting plate, a vertical plate, a horizontal plate, a pin, an inclined plate, rollers, and an angle plate; The mounting plate is used to be installed on the workbench of the bending machine; The upright plate is mounted on the mounting plate; The horizontal plate is mounted on the vertical plate and its horizontal position can be adjusted relative to the vertical plate. The inclined plate is hinged to the horizontal plate via the pin, allowing the inclined plate to swing around the pin. The angle plate is connected between the horizontal plate and the inclined plate to limit the swing angle of the inclined plate so that it matches the angle of the workpiece to be bent. Multiple rollers are provided and are respectively installed on the horizontal plate and the inclined plate to support the workpiece.

[0006] Preferably, the mounting plate is provided with multiple sets of fixing holes, and the upright plate is installed on the mounting plate by selecting different fixing holes to adjust its installation position.

[0007] Preferably, the horizontal plate and the vertical plate are connected by elongated hole bolts, and the horizontal position of the horizontal plate can be adjusted through the elongated hole structure.

[0008] Preferably, it also includes a magnet, which is mounted on the horizontal plate and / or the inclined plate for adsorbing and fixing the workpiece.

[0009] Preferably, the installation position of the magnet is adjustable to change the distance between it and the workpiece, thereby adjusting the magnitude of the magnetic force.

[0010] Preferably, an adjusting screw is provided between the angle plate and the tilt plate for fine-tuning the angle of the tilt plate.

[0011] Preferably, the angle of the angle plate is the same as the angle of the workpiece to be bent.

[0012] The beneficial effects of this invention are as follows: This device, through a bracket structure composed of a horizontal plate and an inclined plate, provides stable and continuous auxiliary support for thin-walled workpieces with long protruding bending lines, effectively counteracting the deformation of the workpiece caused by its own weight and external pressure. Simultaneously, the magnets on the bracket can attract and fix the workpiece, while the roller structure reduces the frictional resistance during workpiece movement. These three elements work together to ensure accurate positioning of the workpiece in the post-positioning stage from three aspects: support, fixation, and smooth feeding. This ensures the stability of the bending and forming dimensions, significantly improving product yield and processing efficiency.

[0013] Furthermore, this bracket design boasts excellent adaptability and flexibility. Its horizontal plate, tilt plate, and overall installation position are all adjustable. In particular, by replacing or fine-tuning the angle plate, the bracket can quickly adapt to workpieces bent at different angles. For extra-long workpieces, multiple brackets can be installed side-by-side on the bending machine's worktable for segmented support, greatly expanding the device's applicability and enabling it to handle various complex bending conditions, making it highly practical.

[0016] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0017] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0018] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings and preferred embodiments.

[0019] like Figure 1 and Figure 2 As shown, the auxiliary support for positioning workpieces in the back of a bending machine according to this utility model is mainly composed of a mounting plate 1, a vertical plate 2, a horizontal plate 3, a pin 4, an inclined plate 5, a roller 6, a magnet 7, and an angle plate 8.

[0020] The mounting plate 1 is fixed to the worktable of the bending machine with bolts. Multiple sets of fixing holes are machined on the mounting plate 1. The vertical plate 2 is connected to one set of fixing holes with bolts. By selecting different sets of fixing holes, the front-to-back position of the vertical plate 2 on the mounting plate 1 can be coarsely adjusted to accommodate different workpiece bending line positions. The horizontal plate 3 is bolted to the top of the vertical plate 2, and an elongated hole is provided at the connection between the horizontal plate 3 and the vertical plate 2. By loosening the bolts, the horizontal plate 3 can be moved horizontally along the direction of the elongated hole, thereby finely adjusting its distance from the edge of the bending machine's worktable to ensure that the workpiece can be accurately supported in the predetermined position.

[0021] The inclined plate 5 is hinged to one end of the horizontal plate 3 via a pin 4, allowing it to swing freely within a certain angle range around the pin 4. The angle plate 8 is bolted to the bottom of both the horizontal plate 3 and the inclined plate 5. The angle plate 8 is pre-machined with a specific angle, the same as the theoretical angle of the workpiece to be bent (e.g., if a 90° workpiece needs to be bent, the angle plate is 90°). Once installed, the angle plate 8 restricts the swing of the inclined plate 5, forming a fixed angle with the horizontal plate 3, thus precisely fitting the bending shape of the workpiece. To further improve accuracy, an adjusting screw is installed between the angle plate 8 and the inclined plate 5. By screwing in or out this screw, the angle of the inclined plate 5 can be finely adjusted to compensate for machining or installation errors and better fit the workpiece.

[0022] Multiple rollers 6 are mounted on the top of the horizontal plate 3 and the inclined plate 5 via brackets. During operation, the bottom surface of the workpiece rests against the rollers on the horizontal plate 3, and the sides rest against the rollers on the inclined plate 5. The rollers 6 provide load-bearing support and allow the workpiece to move easily and smoothly during positioning, reducing friction. Furthermore, magnets 7 are embedded in the horizontal plate 3 and the inclined plate 5. These magnets 7 can be permanent magnets, and their installation height is adjustable (e.g., by providing threaded holes in the plates and securing them with nuts). By adjusting the height of the magnet 7 protruding from the plate surface, the gap between it and the workpiece can be changed, thereby controlling the magnitude of the magnetic attraction to the workpiece. This effectively prevents the workpiece from tilting or shifting while providing support, achieving reliable fixation.

[0023] For large, thin sheet workpieces with a long bending direction, multiple sets of this auxiliary bracket can be installed side-by-side along the length of the worktable of the bending machine (e.g., Figure 1 (Illustrative diagram) This forms a complete support system. Through multi-point segmented support, the bending deformation of the workpiece due to its own weight can be greatly suppressed, ensuring the consistent positioning of the entire long workpiece during the bending process.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
