Description

Technical Field

[0001] This utility model belongs to the field of aluminum stamping and forming, specifically, it relates to an aluminum stamping and forming device with multi-point positioning capability. Background Technology

[0002] Aluminum materials are products made of aluminum and other alloying elements. They are usually first processed into castings, forgings, foils, plates, strips, tubes, rods, profiles, etc., and then made through processes such as cold bending, sawing, drilling, assembly, and coloring. The main metallic element is aluminum, and some alloying elements are added to improve the performance of aluminum materials. Stamping is required in the process of aluminum material processing and forming.

[0003] In the use of aluminum stamping in the market, due to the processing of irregularly shaped sheet aluminum profiles, the existing positioning devices are mostly fixed by two-sided contact, which is not very effective. For example, when there are wavy sides, the positioning structure on both sides cannot adjust and fix the position according to the wavy sides, which can easily cause the aluminum material to shift, affecting the quality of aluminum material processing, making it inconvenient for users, and thus reducing the practicality of stamping. Therefore, we propose an aluminum stamping method with multi-point positioning. In view of this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an aluminum stamping and forming device that can be positioned at multiple points.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A multi-point positioning aluminum stamping forming device includes a base, a top cover on the top of the base, the top cover and the base being supported and fixed by a column, a hydraulic cylinder being fixed in the middle of the top cover, the telescopic end of the hydraulic cylinder being fixed to a drive plate, and a stamping die being provided at the lower end of the drive plate.

[0007] The upper end of the base is horizontally provided with a guide groove for the movement of multiple first L-shaped positioning seats. Multiple symmetrical second L-shaped positioning seats are vertically fixed at the upper end of the base. A first electric push rod is fixed to the top of each of the multiple first L-shaped positioning seats. The telescopic end of each first electric push rod passes through the middle of the first L-shaped positioning seat and is fixed to the first abutment block. A second abutment block is provided on the side of each of the multiple first L-shaped positioning seats. A protrusion for abutting a first thin-film pressure detector is fixed on the inner side of the second abutment block. A second thin-film pressure detector is provided inside the first abutment block. The first thin-film pressure detector and the second thin-film pressure detector are both connected to the circuit of the first pressing indicator light and the second pressing indicator light at the upper end of the first L-shaped positioning seat through wires.

[0008] Each of the second L-shaped positioning seats has a second electric push rod fixed to its top. The telescopic end of each second electric push rod passes through the upper end of the second L-shaped positioning seat and is fixed to the third abutment block. Each third abutment block has a third thin-film pressure detector at its lower end. Each of the second L-shaped positioning seats has a third electric push rod fixed to its back. The telescopic end of each third electric push rod passes through the middle of the second L-shaped positioning seat and is fixed to the fourth abutment block. The surface of the fourth abutment block has a fourth thin-film pressure detector. The third and fourth thin-film pressure detectors are connected to the circuits of the third and fourth pressing indicator lights via wires.

[0009] The base has a controller at its front end.

[0010] Optionally, the base is internally equipped with multiple double-ended lead screws. One end of each double-ended lead screw is rotatably connected to the inner side wall of the base via a bearing, and the other end of each double-ended lead screw is fixed to the output shaft of the self-locking motor via a coupling. Threaded sleeves are installed on the outside of both ends of each double-ended lead screw. The upper ends of the multiple threaded sleeves are respectively fixed to the bottom of multiple first L-shaped positioning seats. A guide block for a guide rod to pass through is fixed at the lower end of each threaded sleeve, and the guide rod is fixedly installed inside the base. The self-locking motor is fixed to the side of the base via a housing.

[0011] Optionally, each first L-shaped positioning seat has a sleeve block fixed on its side for fixing the pen-type electric actuator, and each pen-type electric actuator has an abutment head fixed by screws at its telescopic end, and a dustproof bellows plate is fixed between every two opposing sleeve blocks.

[0012] Optionally, sliding members are fixed on both sides of the drive plate, and each sliding member has a through hole at its end that matches the external dimensions of the support column, and each hole has a ball bearing on its inner wall.

[0013] Optionally, two sets of slide rails are symmetrically fixed at the lower end of the drive plate, and a fixed area for placing the stamping die is provided between the two sets of slide rails. Each slide rail is slidably connected to an L-shaped part for fixing the stamping die at its lower end. Each L-shaped part is threaded to a fixing bolt that abuts against the front end of the slide rail, and each L-shaped part has a limiting hole at its end for threaded connection of a limiting bolt. The upper end of the stamping die has a screw hole for screwing in the limiting bolt.

[0014] Optionally, U-shaped blocks are fixed on all four sides of the stamping die, and a cross laser positioning light is provided in the middle of each U-shaped block. The cross laser positioning light is fixed to the sleeve block by a mounting bolt.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0016] 1. This utility model addresses the issue that in the use of aluminum stamping and forming in the market, due to the processing of irregularly shaped sheet aluminum profiles, existing positioning devices often provide poor positioning by abutting both sides. For example, when there are wavy sides, the positioning structures on both sides cannot adjust their positions according to the wavy sides, easily causing the aluminum profile to shift, affecting the quality of the aluminum profile processing, and making it inconvenient for users, thus reducing the practicality of stamping and forming. This device uses a first L-shaped positioning seat and a second L-shaped positioning seat to cooperate in positioning the processed aluminum profile. The material plays a role in multi-point fixation. Even when facing side walls and wavy irregularly shaped workpieces, multiple first L-shaped positioning seats can be used to abut against the concave and convex points of the wavy side walls under the drive of double-ended lead screws. After abutting, the first and second electric push rods at the top of the first and second L-shaped positioning seats will drive the first and second abutting blocks to abut against the workpiece, providing a downward pressing force to the workpiece. This provides multi-point fixation of the workpiece by lateral and downward forces, thereby ensuring that the workpiece will not shift position during the stamping process.

[0017] 2. This utility model uses multiple first, second, third, and fourth thin-film pressure detectors, along with a first, second, third, and fourth clamping indicator light, to indicate whether the workpiece is secure. This allows the operator to judge the fixation status of the workpiece based on whether the light is on. Specifically, when the first thin-film pressure detector touches the workpiece, it sends an analog signal to the controller. The controller then processes the information and controls the first clamping indicator light to illuminate.

[0032] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] Please see Figures 1 to 10 This utility model provides a technical solution: an aluminum stamping forming device with multi-point positioning, including a base 1, a top cover 2 above the base 1, the top cover 2 and the base 1 being supported and fixed by a column 3, a hydraulic cylinder 4 being fixed in the middle of the top cover 2, the telescopic end of the hydraulic cylinder 4 being fixed to a drive plate 5, and a stamping die 6 being provided at the lower end of the drive plate 5.

[0035] The upper end of the base 1 is horizontally provided with a guide groove for multiple first L-shaped positioning seats 7 to move. Multiple symmetrical second L-shaped positioning seats 8 are vertically fixed at the upper end of the base 1. A first electric push rod 9 is fixed at the top of each of the multiple first L-shaped positioning seats 7. The telescopic end of each first electric push rod 9 passes through the middle of the first L-shaped positioning seat 7 and is fixed to the first abutting block 10. A second abutting block 11 is provided on the side of each of the multiple first L-shaped positioning seats 7. A protrusion for abutting the first thin film pressure detector 12 is fixed on the inner side of the second abutting block 11. A second thin film pressure detector 13 is provided inside the first abutting block 10. The first thin film pressure detector 12 and the second thin film pressure detector 13 are both connected to the first pressing indicator light 14 and the second pressing indicator light 15 at the upper end of the first L-shaped positioning seat 7 through wires.

[0036] Each of the second L-shaped positioning seats 8 has a second electric push rod 16 fixed at its top. The telescopic end of each second electric push rod 16 passes through the upper end of the second L-shaped positioning seat 8 and is fixed to the third abutment block 17. Each third abutment block 17 has a third thin-film pressure detector 18 at its lower end. Each of the second L-shaped positioning seats 8 has a third electric push rod 19 fixed at its back. The telescopic end of each third electric push rod 19 passes through the middle of the second L-shaped positioning seat 8 and is fixed to the fourth abutment block 20. The surface of the fourth abutment block 20 has a fourth thin-film pressure detector 21. The third thin-film pressure detector 18 and the fourth thin-film pressure detector 21 are both connected to the third pressing indicator light 22 and the fourth pressing indicator light 23 by wires.

[0037] The front end of the base 1 is equipped with a controller 24. Considering that aluminum stamping and forming in the market often involves the processing of irregularly shaped sheet aluminum profiles, existing positioning devices often provide poor positioning by abutting from both sides. For example, when there are wavy sides, the positioning structures on both sides cannot adjust their positions according to the wavy sides, which can easily cause the aluminum profile to shift, affecting the quality of the aluminum processing and making it inconvenient for users, thus reducing the practicality of stamping and forming. This device uses the cooperation of the first L-shaped positioning seat 7 and the second L-shaped positioning seat 8 to position the processed aluminum profile. The multi-point fixing function ensures that even when facing side walls and wavy irregularly shaped workpieces, multiple first L-shaped positioning seats 7 can be driven by double-ended lead screws 25 to abut against the concave and convex points of the wavy side walls. After abutting, the first electric push rod 9 and the second electric push rod 16 at the top of the first L-shaped positioning seats 7 and the second L-shaped positioning seats 8 will drive the first abutting block 10 and the second abutting block 11 to abut against the workpiece, providing a downward pressing force to the workpiece. This multi-point fixing of the workpiece by lateral and downward forces ensures that the workpiece will not shift position during the stamping process.

[0038] The base 1 contains multiple double-ended lead screws 25. One end of each lead screw 25 is rotatably connected to the inner wall of the base 1 via a bearing, and the other end of each lead screw 25 is fixed to the output shaft of the self-locking motor 29 via a coupling. Each lead screw 25 has a threaded sleeve 26 installed on both ends. The upper ends of the threaded sleeves 26 are fixed to the bottom of multiple first L-shaped positioning seats 7. A guide block 28 for a guide rod 27 to pass through is fixed to the lower end of each threaded sleeve 26, and the guide rod 27 is fixedly installed inside the base 1. The self-locking motor 29 is fixed to the side of the base 1 by the housing. The self-locking motor 29 drives the double-ended lead screw 25. When the double-ended lead screw 25 is driven to rotate, it will transmit the power to the threaded sleeve 26. The threaded sleeve 26 is displaced along the guide rod 27 under the guidance of the guide rod 27. During this process, the first L-shaped positioning seat 7 moves horizontally with the movement of the threaded sleeve 26. The two first L-shaped positioning seats 7 on the same double-ended lead screw 25 will move towards or away from each other at the same time, thereby fixing or detaching the workpiece.

[0039] Each first L-shaped positioning seat 7 has a sleeve block 30 fixed on its side for fixing the third electric push rod 19. Each pen-type electric push rod 42 has a contact head 31 fixed to its telescopic end by screws. A dustproof bellows plate 32 is fixed between each pair of opposing sleeve blocks 30. Considering that the workpiece needs to be removed after being stamped by the stamping die 6, and in order to facilitate the removal of the workpiece, this utility model drives the contact head 31 to push upward through the telescopic end of the third electric push rod 19, so that the workpiece is pushed out by the contact, thus facilitating the removal of the workpiece by the processing personnel.

[0040] The drive plate 5 has sliding members 33 fixed on both sides. Each sliding member 33 has a through hole at its end that matches the external size of the support column 3. Each hole has a ball bearing 34 on its inner wall. The sliding members 33 guide the displacement of the drive plate 5. When the drive plate 5 moves vertically, it is guided by the sliding members 33 in conjunction with the support column 3. In order to reduce the friction between the inner wall of the sliding members 33 and the outer wall of the support column 3, the ball bearing 34 reduces the friction when the drive plate 5 moves.

[0041] The drive plate 5 has two sets of slide rails 35 symmetrically fixed at its lower end. Between the two sets of slide rails 35, there is a fixed area for placing the stamping die 6. The lower end of each slide rail 35 is slidably connected to an L-shaped part 36 for fixing the stamping die 6. The front end of each L-shaped part 36 is threaded with a fixing bolt 37 that abuts against the front end of the slide rail 35. The end of each L-shaped part 36 is provided with a limiting hole for the threaded connection of a limiting bolt 38. The upper end of the stamping die 6 is provided with a screw hole for the limiting bolt 38 to be screwed in. By setting the slide rails 35 and the L-shaped parts 36 together, the stamping die 6 is fixed, which makes it convenient for the user to replace the stamping die 6. When replacing, loosen the limiting bolt 38, then loosen the fixing bolt 37, and then move the L-shaped part 36 along the slide rails 35 to both sides. At this time, the stamping die 6 can be removed and replaced.

[0042] The stamping die 6 has U-shaped blocks 39 fixed on all four sides. Each U-shaped block 39 has a cross laser positioning light 40 in the middle. The cross laser positioning light 40 is fixed to the sleeve block 30 by mounting bolts 41. By setting the cross laser positioning light 40, the user can easily know the stamping area during the stamping process by the rectangular light formed by the four cross laser positioning lights 40, which makes it convenient for the user to place the processing material in the processing area.

[0043] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
