Description

Technical Field

[0001] This utility model relates to the field of aluminum plate bending processing technology, and more specifically, to a multi-angle positioning fixture for aluminum plate bending. Background Technology

[0002] Aluminum sheet refers to sheet-like products made from pure aluminum or aluminum alloy through processes such as rolling and shearing. It has a wide range of thicknesses (usually from 0.2mm to over 500mm) and has many excellent properties. In terms of material, pure aluminum sheet is soft and has good ductility. Due to its lightweight and high strength characteristics, it is widely used. Aluminum sheet is suitable for complex processing, and bending is a key process in its forming.

[0003] Currently, most common positioning fixtures are fixed or single-angle adjustable structures. The former achieves single-angle positioning by preset pads or stops, and the entire fixture needs to be replaced when changing models, resulting in poor adaptability and making it impossible to produce aluminum plates of multiple specifications. The latter, although it can adjust the angle, is limited to a few common angles and cannot freely and quickly change to a specified angle. Switching is also time-consuming. Overall, it cannot meet the bending needs of more angle settings, and therefore cannot meet the needs of efficient production.

[0004] In summary, in order to meet the demand for rapid changes in multiple angles during the bending production of multi-specification aluminum sheets, it is necessary to solve the problems of poor adaptability, limited angle adjustment, and time-consuming switching of existing positioning fixtures, so that the fixtures can flexibly adapt to different angle settings and improve production efficiency.

[0010] In a preferred embodiment, the pushing mechanism includes a straight pushing component and a rotating component.

The bending part of the aluminum plate is subjected to uniform and regular force, thereby improving the quality of the aluminum plate after bending. Attached Figure Description

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Refer to the instruction manual appendix Figures 1 to 6 A multi-angle positioning fixture for bending aluminum sheets includes a worktable 1. A support plate 2 and an N-shaped plate 14 are fixedly connected to the upper end of the worktable 1. A positioning plate 3 is positioned between the support plate 2 and the N-shaped plate 14. A pushing mechanism is mounted on the N-shaped plate 14. The positioning plate 3 is connected to the output end of the pushing mechanism. The pushing mechanism drives the positioning plate 3 to move closer to or away from the support plate 2, and works with the support plate 2 to press and fix the aluminum sheet. A support frame 5 is fixedly connected to one side of the worktable 1. A disc 6 is fixedly connected to the upper end of the support frame 5. A fixed locating device rotatably connects the disc 6 and the worktable 1. Positioning shaft 7 and adjusting plate 9 are fixedly connected at one end. A pushing mechanism is installed on the worktable 1. A bending plate 10 is installed on the output end of the pushing mechanism. The pushing mechanism is used to drive the bending plate 10 to approach or move away from the aluminum plate. When the bending plate 10 approaches until it contacts the aluminum plate, it bends the aluminum plate. An angle scale line 11 centered on the positioning shaft 7 is set on the upper end of the worktable 1. A positioning cylinder 12 is installed on the worktable 1. A positioning column 13 is fixedly connected to the output end of the positioning cylinder 12. The positioning cylinder 12 is used to push the positioning column 13 to move.

[0025] It should be noted that the front edge of the positioning shaft 7 is on the extended plane of the front surface of the support plate 2. In this way, when the positioning plate 3 pushes the aluminum plate to fit against the surface of the support plate 2 and the positioning shaft 7, the aluminum plate can be kept straight. The bending plate 10 is located at the top of the worktable 1, which can accurately push the aluminum plate to move when moving. The zero mark of the angle scale line 11 is set on the vertical line from the center of the positioning shaft 7 to the left side of the worktable 1. In this way, the aluminum plate is parallel to the zero mark of the angle scale line 11 when it is fixed at the beginning stage, which means that the bending angle is zero.

[0026] Another embodiment based on the angle scale line 11 design, please refer to Figure 6 Because the angle scale line 11 is hidden and inconvenient to refer to when adjusting the adjustment plate 9 to a suitable angle, its position on the workbench 1 can be removed. Instead, an angle scale 18 can be set on the surface of the disc 6, and an arc-shaped vertical plate 16 can be fixedly connected to the upper end of the adjustment plate 9. A pointer 17 that fits on the surface of the disc 6 can be fixedly connected to the upper end of the arc-shaped vertical plate 16. In this way, when adjusting the adjustment plate 9, the arc-shaped vertical plate 16 will drive the pointer 17 to rotate synchronously. The pointer 17 points to the angle scale 18, which makes it easy to judge the angle of adjustment of the adjustment plate 9 and make it easy to check.

[0027] Refer to the instruction manual appendix Figure 4 The pushing mechanism includes a driving component and a guiding component. The driving component is used to push the positioning plate 3 to move, and the guiding component is used to control the positioning plate 3 to move along a preset direction.

[0028] It should be noted that the pushing mechanism consists of two parts: a driving component and a guiding component. The driving component and the guiding component work together to control and push the positioning plate 3 to move smoothly.

[0029] Refer to the instruction manual appendix Figure 4 The drive assembly includes a threaded rod 401 threaded through the middle of the N-type plate 14, a turntable 402 fixedly connected to one end of the threaded rod 401, and a gripping rod 403 fixedly connected to the turntable 402 at an eccentric position. The other end of the threaded rod 401 is rotatably connected to the positioning plate 3.

[0030] It should be noted that when the hand grips the lever 403, the turntable 402 rotates, and the turntable 402 rotates the threaded rod 401. Therefore, the threaded rod 401 moves back and forth through the threaded N-type plate 14, which in turn pushes the positioning plate 3 to move.

[0031] Refer to the instruction manual appendix Figure 4 The guide assembly includes a stabilizing plate 404 movably connected to the outer side of the threaded rod 401 near the turntable 402, two retaining rings 405 fixedly connected to the outer side of the threaded rod 401, and two fixing rods 406 movably connected to the N-shaped plate 14. The two retaining rings 405 are respectively located on the front and rear sides of the stabilizing plate 404, and the two ends of the fixing rods 406 are fixedly connected to the positioning plate 3 and the stabilizing plate 404 respectively.

[0032] It should be noted that when the threaded rod 401 pushes the positioning plate 3 to move, the stabilizing plate 404 simultaneously drives the two fixed rods 406 to move, and the two fixed rods 406 further drive the positioning plate 3 to move smoothly.

[0033] Another embodiment based on the pressing mechanism: the entire pressing mechanism can be replaced with a single cylinder that drives it. The output end of the single cylinder is directly fixed to the positioning plate 3. At the same time, a contact sensor is installed on the side of the positioning plate 3 facing the support plate 2. This allows for faster and more stable control of the cylinder to push the positioning plate 3 to move. The positioning plate 3 quickly presses against the surface of the aluminum plate, and the contact sensor provides a contact feedback signal to facilitate the provision of appropriate pressing force to fix the aluminum plate.

[0034] Refer to the instruction manual appendix Figure 2 and Figure 5 The pushing mechanism includes a direct pushing component and a rotating component. The direct pushing component is installed on the output end of the rotating component, and the bending plate 10 is installed on the output end of the direct pushing component. The direct pushing component is used to drive the bending plate 10 to perform linear motion, and the rotating component is used to drive the bending plate 10 to perform circular motion.

[0035] It should be noted that the pushing mechanism consists of a direct pushing component and a rotating component. The direct pushing component and the rotating component work together to provide the appropriate thrust for the bending plate 10 pairs of aluminum plates during bending.

[0036] Refer to the instruction manual appendix Figure 2 and Figure 5 The direct push assembly includes a rotary table 801 located at the bottom of the workbench 1, a raised platform 802 fixedly connected to the upper end of the rotary table 801, and a bending cylinder 803 fixedly connected to the upper end of the raised platform 802. The output end of the bending cylinder 803 is fixedly connected to the surface of the bending plate 10, and the bending cylinder 803 is used to push the bending plate 10 to make linear motion.

[0037] It should be noted that when the bending cylinder 803 is activated, it pushes the bending plate 10 to move, and the bending plate 10 pushes the aluminum plate to move linearly.

[0038] Refer to the instruction manual appendix Figure 2 and Figure 5 The rotating assembly includes a support frame 804 fixedly connected to the bottom of the worktable 1 and a rotating motor 805 fixedly connected to the bottom of the support frame 804. The rotating table 801 is rotatably connected between the support frame 804 and the worktable 1 via a rotating shaft. The output end of the rotating motor 805 is fixedly connected to the rotating shaft of the rotating table 801. The rotating motor 805 is used to drive the rotating table 801 to rotate.

[0039] It should be noted that the starting motor 805 drives the rotary table 801 to rotate, and the rotary table 801 drives the raised platform 802 and the bending cylinder 803 to rotate, thereby changing the direction of the thrust of the bending plate 10 on the aluminum plate and realizing the bending of the aluminum plate.

[0040] Refer to the instruction manual appendix Figure 3The upper end of the support plate 2 is provided with a length measurement scale line 15, and the zero scale line of the length measurement scale line 15 is set at the starting position on the left.

[0041] It should be noted that the distance from the left edge of the support plate 2 to the positioning shaft 7 is constant. Thus, the aluminum plate can be measured at the support plate 2 using the length measuring scale line 15 to complete the entire length measurement. Then, the plate can be moved to the left by a certain length. By observing the scale position reached by the right end of the aluminum plate, and based on the known distance from the left edge of the support plate 2 to the positioning shaft 7, the initial total length can be added to this distance and the new measured length can be subtracted. This allows for reasonable control of the length of the bent part of the aluminum plate.

[0042] Working principle: First, set the required bending angle of the aluminum plate. Rotate the adjusting plate 9 and observe the angle scale line 11 to rotate the adjusting plate 9 to the appropriate angle position. Activate the positioning cylinder 12 to push the positioning column 13 to move. The positioning column 13 abuts against the surface of the adjusting plate 9 to support it. Then, place the aluminum plate in front of the support plate 2. Measure the total length using the length measuring scale line 15. Knowing the distance from the left edge of the support plate 2 to the positioning shaft 7, and the required bending length of the aluminum plate, calculate and move the aluminum plate to the left by a specified distance. Then, use the pressing machine... The mechanism involves holding the lever 403 to rotate the turntable 402, which in turn rotates the threaded rod 401 and pushes the positioning plate 3. With the synchronous pushing action of the two fixed rods 406, the positioning plate 3 and the support plate 2 together press and fix the aluminum plate. Finally, the bending cylinder 803 in the pushing mechanism is activated to push the bending plate 10 to move linearly. At the same time, the rotating motor 805 is activated to drive the rotating table 801 to rotate, so that the pushing force of the bending plate 10 on the bending part of the aluminum plate is converted into a uniform bending force until the aluminum plate is bent and pressed against the surface of the adjusting plate 9, thus completing the controllable angle bending of the aluminum plate.

[0043] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
