Description

Technical Field

[0001] This invention relates to the field of metal plastic processing technology, specifically a bending device for aluminum processing. Background Technology

[0002] Aluminum bending is a process used to produce bent aluminum materials. Multi-curvature aluminum materials refer to aluminum materials with multiple bending sections of different curvatures. Multi-curvature aluminum materials have significant market value and application prospects in the automotive, construction, industrial equipment, robotics, and consumer goods sectors. However, existing bending devices generally suffer from the following drawbacks:

[0003] Poor adaptability and flexibility: Each time a new product is produced, the mold and fixture need to be changed and adjusted, which is cumbersome and time-consuming, making it difficult to adapt to the modern production needs of small batches and multiple varieties.

[0004] Low level of automation and intelligence: Most aluminum bending machines cannot automatically load and unload materials, and most still require manual loading. Furthermore, machine start-up and processing modes need to be manually adjusted, resulting in high industrial costs.

[0005] Single-curvature surface bending only: Traditional bending machines mostly use a single bending die to produce aluminum materials with a single curvature surface, but cannot produce aluminum materials with multiple curvature surfaces. Summary of the Invention

[0006] The purpose of this invention is to provide a bending device for aluminum processing to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a bending device for aluminum processing, comprising an outer frame, a feeding device, a bending device, and a top die device. The feeding device is disposed on the left and right sides of the outer frame, and two upper top die devices are disposed on the top of the outer frame. A lower top die device is disposed on the bending device. The bending device is disposed inside the outer frame, and two bending arms are mounted on the bending device. One end of the bending arm rotates by a rotary motor, and the other end rotates circumferentially with the bending device via a supporting guide rail underneath. A clamping guide rail is disposed on the bending arm, and a clamp is mounted on the clamping guide rail. The clamp moves along the clamping guide rail. By controlling the rotation angle of the bending arm and the movement of the clamp on the clamping guide rail, the clamp can be moved to any position within the coverage area of ​​the bending arm.

[0008] Furthermore, the fixture is equipped with clamping jaws inside, which are rotated by a clamping rotary motor. The fixture can accept material feeding and discharging from different angles from the feeding device. The clamping jaws are equipped with three rotatable rotors inside. When the rotors are driven to rotate by the motor, they can provide a feeding force to the aluminum material to adjust the processing position of the aluminum material in the bending machine.

[0009] Furthermore, the clamping jaws consist of three jaw rotors. When the aluminum material needs to be clamped, the three jaw rotors are aligned and clamped. The coordinated operation of the clamping jaws and the clamp can transport the aluminum material in and out, enabling the aluminum material to complete the processes of feeding, unloading, adjusting position, and clamping within the device.

[0010] Furthermore, the upper ejector device is mounted on the upper ejector slide rail, and the upper ejector device can move left and right on the upper ejector slide rail, providing the upper ejector with the ability to adjust the processing position left and right. At the same time, the upper ejector frame is also provided with a slide rail that moves back and forth, providing the ejector mounted on the upper ejector device with the ability to adjust the processing position back and forth.

[0011] Furthermore, the lower die device consists of a lower die, a lower die receiving plate, and a lower die guide rail. The lower die receiving plate is mounted on the bending machine, and the lower die receiving plate is provided with multiple standard die rails. Multiple dies can be installed on the standard die rails depending on the processing situation. The number and position of the dies are determined by the required curvature of the aluminum material to achieve aluminum material processing with different curvatures.

[0012] Furthermore, the lower top die guide rail is located at the top of the bending machine, and a screw motor is located at the top of the bending machine to drive the lower top die receiving plate to move back and forth along the lower top die guide rail.

[0013] Furthermore, feeding devices are installed at both ends of the outer frame. The feeding devices consist of a three-jaw chuck and three feed rollers. When the feed rollers are driven to rotate, they can provide feeding force to the aluminum material. At the same time, when the aluminum material needs to be fixed, the feed rollers can keep the aluminum material fixed by self-locking.

[0014] Furthermore, after the feeding device feeds the aluminum material into the bending machine, the clamps set on the bending machine receive the aluminum material and send it to the clamps on the other side. At this time, the aluminum material is in the middle of the upper and lower ejector devices. The bending machine works, and the two bending arms on the left and right bend towards the lower ejector device. The aluminum material is pushed to the required curvature by the lower ejector device. Then, according to the needs of the aluminum material, the two upper ejector devices on the left and right move to the required position through the upper slide rail, and the bending arms rotate towards the upper ejector device to complete the other curvature processing of the aluminum material.

[0015] Furthermore, the outer frame is equipped with upper mold mounters on both the left and right sides, and the upper mold mounters are provided with upper mold slide rails.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention, through the coordinated operation of a feeding device, clamps, a bending machine, and a bending arm, not only automates the bending process of aluminum materials but also enables precise adjustment of the bending process and controllable processing details. The aluminum material is fed into the machine by the feeding device. Through the coordinated movement of the bending machine and the bending arm, the aluminum material to be processed is clamped by the clamps on the bending arm and sent to a designated position. After processing, it is then sent by the clamps to another feeding device, completing the automated production of aluminum materials. Furthermore, if the curvature quality of the produced aluminum material is poor, the clamping force, bending time, and top die can be precisely adjusted to ensure that the forming quality of the aluminum material meets the required standards.

[0018] 2. The present invention has two movable top molds set on the upper end of the outer frame. With the above-mentioned feeding and unloading process, after the first curvature requirement of the aluminum material is processed, the top mold is moved to the specified position. Then, through the coordinated work of the clamp and the bending device, the bending requirements of other curvatures can be completed. This device can realize the bending processing of aluminum material with multiple curvatures, which not only saves the cost of multiple sets of clamps in traditional aluminum material processing, but also saves the handling cost of multiple workstations in aluminum material processing.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1 to 7 As shown, a bending device for aluminum processing includes an outer frame 1, a feeding device 6, a bending device 5, an upper ejector die device 3, and a lower ejector die device 4. The feeding device 6 is arranged on the left and right sides of the outer frame. Two upper ejector die devices 3 are arranged at the top of the outer frame 1, and a lower ejector die device 4 is arranged on the bending device 5. The bending device 5 is arranged inside the outer frame 1. Two bending arms 501 are installed on the bending device 5. One end of the bending arm 501 is connected to the bending device 5 through a rotary motor 502, and the other end is connected to the bending device 5 through a support guide rail 504 to achieve circumferential rotation. A clamping guide rail 505 is arranged on the bending arm 501, and a clamp 2 is installed above the clamping guide rail 505. The clamp 2 can move on the clamping guide rail 505. By controlling the rotation angle of the bending arm 501 and the movement of the clamp 2 on the clamping guide rail 505, the clamp 2 can be moved to any position in the coverage area of ​​the bending arm 501.

[0029] The fixture 2 is equipped with a fixture jaw 202, which is rotated by a fixture rotary motor 203. The fixture 2 can accept aluminum materials from different angles from the feeding device 6. At the same time, the fixture jaw 202 is equipped with three rotatable jaw rotors 205. When the jaw rotors 205 are driven to rotate by the motor, they can provide a feeding force to the aluminum material and further adjust the processing position of the aluminum material in the bending machine 5.

[0030] The clamping jaws 202 consist of three clamping rotors 205. When the aluminum material needs to be clamped, the three clamping rotors 205 are centered and clamped like a three-jaw chuck on a machine tool. The clamping jaws 202 and the clamp 2 work together to transport the aluminum material in and out, so that the aluminum material can complete the processes of feeding, unloading, adjusting position and clamping in the device.

[0031] The upper mold mounter 102 is installed above the outer frame 1. An upper mold slide rail 103 is provided below the upper mold mounter 102. The upper mold device 3 is installed on the upper mold slide rail 103, which enables the upper mold device 3 to move left and right.

[0032] The upper ejector device 3 consists of upper ejector left and right guide rails 301, upper ejector frame 302, upper ejector front and rear guide rails 303, and upper ejector 304. The upper ejector left and right guide rails 301 are connected to the upper ejector slide rail 103. The upper ejector 304 is installed on the upper ejector front and rear guide rails 303 to realize the back and forth movement of the upper ejector 304. Considering the overall cooperation of the upper ejector device 3, the upper ejector 304 can move left, right, back and forth inside the device.

[0033] The lower ejector device 4 consists of a lower ejector 401, a lower ejector guide rail 402, and a lower ejector receiving plate 403. The lower ejector device 4 is mounted on the bending machine 5. The lower ejector device 4 is driven to move back and forth by the screw motor 503 on the bending machine 5 and the lower ejector guide rail 402. The lower ejector 401 is mounted on the lower ejector receiving plate 403. Multiple ejectors can be installed depending on the processing situation.

[0034] Feeding devices 6 are provided at the left and right ends of the outer frame 1. The feeding device 6 consists of a three-jaw chuck 602 and three feed rollers 601. Similar to the clamp 2, the feed rollers 601 can provide feeding force to the aluminum material when driven to rotate by the system.

[0035] The working principle of the automated aluminum bending process in this embodiment is as follows:

[0036] Aluminum material feeding principle: After the previous aluminum material bending process, the new aluminum material enters from the feeding device 6 on the left side of the outer frame 1. The three-jaw chuck 602 on the feeding device 6 clamps and holds the aluminum material. The feed roller 601 wraps around the aluminum material and rotates to feed the aluminum material. The clamp 2 on the bending machine 5 moves to the feeding position determined by the system. The clamp rotation motor 203 on the clamp 2 is aligned with the incoming material. As the aluminum material enters the clamp 2, the clamp 2 also holds the aluminum material through the clamp jaws 202 and feeds the aluminum material further through the clamp rotor 205. At the same time, another bending arm also moves another clamp to the corresponding feeding position to receive the aluminum material transported from the first clamp 2. At this time, the aluminum material feeding work is completed.

[0037] Aluminum material processing principle: After the above aluminum material feeding work is completed, the aluminum material is held by the two clamps 2 on the left and right. At this time, the aluminum material is between the upper ejector device 3 and the lower ejector device 4. After the two clamps 2 transport the aluminum material to the predetermined processing position, the bending arm 501 rotates towards the lower ejector device 4. The clamps 2 and the bending arm 501 rotate together so that the aluminum material touches the lower ejector device 4. Then, according to the bending requirements of different aluminum materials, the clamps 2 and the bending arm 501 rotate together so that the aluminum material is further bent into the required curvature.

[0038] Aluminum material discharge principle: After the aluminum material is processed into the required curvature, it is transported by the clamping jaws 202 and clamping rotors 205 on the left and right clamps 2. Although the aluminum material has different curvatures, the left and right clamps 2 are like two robotic arms to transport the aluminum material to the right feeding device 6. Finally, the three-jaw chuck 602 and the feed roller 601 clamp and transport the aluminum material for discharge.

[0039] The principle of multi-curvature bending processing of aluminum materials in this embodiment is as follows:

[0040] The lower ejector device 4 consists of a lower ejector die 401, a lower ejector die receiving plate 403, and a lower ejector die guide rail 402. After the aluminum material enters the predetermined processing position, the lead screw motor 503 on the bending machine 5 pushes out the lower ejector device 4. In conjunction with the bending operation of the bending machine 5, the aluminum material is pushed to the lower ejector die 401. As the force increases, the aluminum material gradually deforms and bends. After the predetermined processing force is completed and no further bending is required, the lower ejector device 4 is retracted by the lead screw motor 503 to a position away from the aluminum material, which facilitates the discharge of the aluminum material.

[0041] For bending with multiple curvatures, the lower ejector device 4 remains in the processing state or retracts, while the upper ejector device 3 moves from the non-processing position to the processing position. The upper ejector device 3 is mounted on the upper ejector device mount 102 on the outer frame 1. An upper ejector device slide rail 103 is provided below the upper ejector device mount 102, which allows the upper ejector device 3 to move left and right inside the machine. The upper ejector device consists of the upper ejector device left and right guide rails 301, the upper ejector device frame 302, the upper ejector device front and rear guide rails 303, and the upper ejector device 304. The upper ejector device 304 is mounted on the upper ejector device frame 302 via the upper ejector device front and rear guide rails 303. Through the action of the upper ejector device front and rear guide rails 303, the upper ejector device 304 can move back and forth. Combined with the left and right movement of the upper ejector device frame 302 mounted on the upper ejector device left and right guide rails 301, the upper ejector device can move back and forth and left and right inside the machine.

[0042] According to the above-mentioned movement method of the upper ejector device 3, after the aluminum material is processed to the first curvature, the left and right upper ejector devices 3 move to the positions set by the system. The bending puller 5 drives the bending puller arm 501 to rotate towards the upper ejector device. At the same time, the clamp 2 and the clamp chuck 202 cooperate to provide bending force. Under the action of bending force, the aluminum material completes the subsequent curvature processing.

[0043] The aluminum bending process in this embodiment can not only be bent in the middle of the aluminum material, but also at other positions. The different processing positions of the aluminum material can be adjusted by the asymmetrical positions of the left clamp 2 and the right clamp 2. At the same time, the two upper mold devices 3 on the left and right are not necessarily symmetrically arranged, and their positions can be adjusted according to different needs. However, the above working principle demonstrates the working principle of this patent for multi-curvature and automated processing of aluminum materials.

[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
