Description

Technical Field

[0001] This invention relates to the technical field of automotive swing arm processing, and in particular to an automotive swing arm flanging and shaping machine. Background Technology

[0002] The control arm, also known as the suspension arm, is a core load-bearing and guiding component of the automotive suspension system. It is mainly divided into upper and lower control arms and is widely used in various vehicle types, including passenger cars and SUVs. Its primary function is to transmit and buffer various loads between the vehicle body and wheels, constrain wheel movement, and directly determine the vehicle's driving stability, handling precision, and driving safety. Automotive control arms are mostly made of high-strength steel, aluminum alloy, and other sheet metal through multiple stamping processes. Flanging and shaping is a key process in the control arm forming process, directly affecting the dimensional accuracy, assembly coaxiality, structural rigidity, and fatigue strength of the control arm. If the flanging and shaping of the control arm has large deviations, deformation, springback, burrs at the edges, or irregular contours, it will not only lead to misalignment and excessive clearance between the control arm and chassis components, but also cause abnormal suspension noise and wheel alignment parameter deviations during vehicle operation. With the rapid development of the new energy vehicle and high-end passenger vehicle industries, the production requirements for lightweight, high-precision, and high-reliability vehicles are continuously upgrading, placing more stringent standards on the flanging and shaping accuracy, forming consistency, and processing efficiency of automotive control arms.

[0003] Currently, most automotive control arm flanging and shaping processes are completed using traditional stamping dies in conjunction with ordinary flanging equipment. The overall processing technology and equipment structure have many inherent defects. For example, in the existing patent with technical announcement number CN206392707U, a flanging and shaping die for an automotive control arm is disclosed, which includes an upper frame, a lower frame, an upper die body, and a lower die body. The upper and lower pressure devices work together to press the workpiece, and the slider drives the upper die insert to achieve flanging and shaping.

[0004] During the use of existing equipment, it was found that after the existing equipment has formed the flanging process of the automobile swing arm, it is not convenient to reshape the shape after flanging, which reduces the consistency of product forming and makes it difficult to inspect the shape of the formed automobile swing arm, thus reducing the reliability of the processing quality. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides an automotive swing arm flanging and shaping machine that simultaneously extrudes and shapes different positions after flanging, improves the consistency of the product shape after shaping, improves the processing quality, and improves the reliability of automotive swing arm processing quality control by detecting the shape of the formed automotive swing arm through a detection mechanism.

[0006] The present invention relates to an automotive swing arm flanging and shaping machine, comprising a base and a lower mold;

[0007] The lower mold is slidably mounted on the upper part of the base; it also includes a support assembly, a guide assembly, a detection mechanism, an elastic assembly, a flanging mold, an upper mold, an edge shaping mold, and a side shaping mold;

[0008] The flanging mold is set at the top of the base, and the lower mold slides through the inside of the flanging mold;

[0009] The upper mold is mounted on the support assembly;

[0010] The edge shaping mold is slidably mounted on the outer wall of the upper mold. The support component is used to drive the upper mold to move up and down, and also provides power for the sliding of the edge shaping mold.

[0011] The bottom shape of the edge shaping mold matches the edge shape of the automobile swing arm after flanging;

[0012] Two sets of side shaping molds are arranged on both sides of the lower mold through a guide assembly that moves in opposite directions. The guide assembly is set on the base and the support assembly and is used to provide power for the sliding of the two sets of side shaping molds.

[0013] The inspection mechanism is located at the rear of the base and is used to inspect the shape of the formed car swing arm.

[0014] An elastic component is located at the bottom of the lower mold, providing elastic support. The automotive swing arm flat blank is placed at the top of the lower mold. Then, the support component moves the upper mold downwards. This downward movement pushes the blank and lower mold downwards, embedding the blank into the flanging mold. Since the edge of the blank is larger than the inner diameter of the flanging mold, the cooperation of the lower mold, flanging mold, and upper mold causes the edge of the blank to be flanged upwards, simultaneously extruding and shaping the blank. After the automotive swing arm is formed, the upper mold moves upwards, and the elastic component pushes the lower mold upwards to reset. At this point, the formed automotive swing arm is separated into upper and lower sides. Instead of being clamped by the lower and upper molds, the two sets of side forming molds are moved closer to each other by the guide component. After the two sets of side forming molds close, the outer edge of the car swing arm after being turned up is subjected to secondary extrusion and shaping. At the same time, the support component drives the edge forming mold to slide down, so that the bottom end of the edge forming mold contacts and presses the top edge of the car swing arm after it is turned up. This achieves simultaneous extrusion and shaping of different positions after turning, improving the consistency of the product shape after shaping and improving the processing quality. Subsequently, the shape of the formed car swing arm is inspected by the inspection mechanism, which improves the reliability of the control of the processing quality of the car swing arm.

[0029] Multiple sets of first springs are respectively fitted onto multiple sets of guide pillars; the second lifting platform is driven to slide downwards by the third hydraulic cylinder, causing the second lifting platform to move the two sets of support arms downwards. After the two sets of support arms move downwards, they drive the two sets of first inclined blocks downwards, causing the two sets of first inclined blocks to slide and push the two sets of second inclined blocks to move through the cooperation of the inclined surfaces. After the two sets of second inclined blocks move, they drive the two sets of side shaping molds to move in opposite directions, realizing the secondary extrusion and shaping of the outer edge of the car swing arm after it is flipped upwards by the two sets of side shaping molds. When the two sets of first inclined blocks move upwards and reset, the multiple sets of first springs elastically support the multiple sets of guide pillars, causing the multiple sets of guide pillars to drive the two sets of side shaping molds to slide and reset.

Detailed Implementation

[0065] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0066] Example 1

[0067] like Figures 1 to 10As shown, the present invention provides an automotive swing arm flanging and shaping machine, the core components of which include a base 101, a lower mold 102, a support assembly, a guide assembly, a detection mechanism, an elastic assembly, a flanging mold 103, an upper mold 104, an edge shaping mold 105, and a side shaping mold 106. The lower mold 102 is slidably mounted on the upper part of the base 101 in the vertical direction. The flanging mold 103 is fixedly set on the top of the base 101 and located on the periphery of the lower mold 102. The lower mold 102 penetrates the interior of the flanging mold 103 and can move up and down within it. The upper mold 104 is mounted on the movable end of the support assembly and is driven by the support assembly to move vertically up and down. The edge shaping mold 105 is slidably mounted on the outer wall of the upper mold 104. The bottom contour of the edge shaping mold 105 is constructed to precisely match the preset edge shape of the automotive swing arm after flanging. Two sets of side shaping molds 106 are respectively arranged on the left and right sides of the lower mold 102 and can be driven by the guide assembly to move in opposite directions.

[0068] The inspection mechanism is located at the rear of the base 101 to inspect the shape of the molded car swing arm. The elastic component is located at the bottom of the lower mold 102 and provides it with continuous elastic support.

[0069] In this embodiment, the support assembly serves as the main power output and execution unit. Specifically, it includes a support base 201 fixed to the top of the base 101, a guide column 202 vertically installed between the base 101 and the support base 201, a first lifting platform 203 slidably mounted on the guide column 202, a first hydraulic cylinder 204 with its fixed end installed on the support base 201 and its movable end connected to the first lifting platform 203, and a second hydraulic cylinder 205 with its fixed end installed on the first lifting platform 203 and its movable end connected to the top of the edge forming mold 105. The top of the upper mold 104 is fixedly connected to the bottom of the first lifting platform 203. Through the above structure, the first hydraulic cylinder 204 drives the first lifting platform 203 to drive the upper mold 104 to achieve the main lifting action, while the second hydraulic cylinder 205 independently drives the edge forming mold 105 to achieve the auxiliary lifting action relative to the upper mold 104. The guide column 202 provides precise vertical guidance for the first lifting platform 203, ensuring the alignment accuracy when the upper mold 104 and the lower mold 102 are closed.

[0070] It should be understood that, in order to ensure good lubrication of all moving parts and reduce wear, self-lubricating bushings or grease nipples for periodic grease filling are provided at the sliding mating surfaces of the guide column 202 and the first lifting platform 203. At the same time, anti-loosening and sealing structures are provided at the pipe interfaces of the first hydraulic cylinder 204 and the second hydraulic cylinder 205 to prevent hydraulic oil leakage. The upper mold 104 and the lower mold 102 are both made of wear-resistant tool steel and are quenched to improve their surface hardness and service life.

[0071] As an alternative, the first hydraulic cylinder 204 and the second hydraulic cylinder 205 can also be powered by electric actuators or pneumatic cylinders to adapt to production environments with different cleanliness requirements or energy consumption standards.

[0072] In this embodiment, the flat blank of the car swing arm is accurately placed on the top of the lower mold 102 and initially positioned by the positioning structure. Then, the first hydraulic cylinder 204 drives the first lifting platform 203 to move the upper mold 104 downwards rapidly. The upper mold 104 first contacts the blank and pushes the blank and the lower mold 102 together to overcome the resistance of the elastic component and move downwards, so that the edge of the blank is embedded in the internal cavity of the flanging mold 103. Since the planar size of the blank is larger than the inner diameter of the flanging mold 103, the lower mold 102, the flanging mold 103 and the upper mold 104 work together to bend and fold the edge of the blank upwards and press the main body into shape. When the car... After the main body of the swing arm is formed by flanging, the first hydraulic cylinder 204 drives the upper mold 104 to move upward back, while the elastic component pushes the lower mold 102 to reset upward. At this time, the formed car swing arm is clamped between the lower mold 102 and the upper mold 104. Then, the guide component drives the two sets of side shaping molds 106 to move closer and close to each other, and performs secondary extrusion shaping on the outer side wall edge of the car swing arm after flanging upward. At the same time, the second hydraulic cylinder 205 drives the edge shaping mold 105 to slide downward, so that its bottom end is in close contact with the top edge of the car swing arm after flanging upward and applies pressure, thereby achieving synchronous and precise shaping of different parts after flanging.

[0073] Through the above working process, this embodiment achieves simultaneous extrusion and shaping at different positions after flanging, improving the consistency of the product shape and dimensional accuracy after shaping. At the same time, since the movements of the edge shaping mold 105 and the side shaping mold 106 are based on the same forming datum, the cumulative error caused by multiple positioning is eliminated. Compared with the existing equipment that can only achieve shaping in a single direction, this embodiment solves the technical problems of uneven springback and contour distortion after flanging of the swing arm by multi-dimensional synchronous shaping in the upper, lower and lateral directions.

[0074] Example 2

[0075] like Figures 1 to 10As shown in the figure, based on Embodiment 1, the automotive swing arm flanging forming machine of the present invention further describes in detail its guiding component, elastic component, detection mechanism, and auxiliary loading and unloading mechanism. The guiding component specifically includes a second lifting platform 301, a third hydraulic cylinder 302, a support arm 303, a first inclined block 304, a second inclined block 305, a guide rail 306, a guide seat 307, a guide post 308, and a first spring 309. The second lifting platform 301 is also slidably mounted on the guide post 302 and is controlled by the first... Driven by three hydraulic cylinders 302, the fixed end of the third hydraulic cylinder 302 is mounted on the support base 201, while its moving end is connected to the second lifting platform 301. The top ends of the two sets of support arms 303 are respectively fixedly connected to the left and right sides of the second lifting platform 301. The two sets of first inclined blocks 304 are respectively fixedly installed at the bottom ends of the two sets of support arms 303. The two sets of second inclined blocks 305 are respectively fixedly installed on the outer walls of the two sets of side forming molds 106, and the two sets of second inclined blocks 305 are slidably installed on the base 10 via guide rails 306. At the top of the base 101, multiple sets of guide seats 307 are fixedly mounted on the base 101. Multiple sets of guide pillars 308 are slidably inserted into the multiple sets of guide seats 307, and their ends are fixedly connected to the outer side walls of the two sets of side forming molds 106. Multiple sets of first springs 309 are respectively fitted onto the multiple sets of guide pillars 308 and provide elastic restoring force. The elastic component includes telescopic pillars 401 and second springs 402. Multiple sets of telescopic pillars 401 are fixedly installed on the outer side walls of the base 101, and their moving ends are connected to the bottom end of the lower mold 102. Multiple sets of first springs 309 are respectively fitted onto the multiple sets of guide pillars 308 and provide elastic restoring force. Two springs 402 are respectively mounted on multiple sets of telescopic columns 401. The detection mechanism consists of a housing 501, a conveying roller 502, a C-shaped bracket 503 and a vision camera 504. The housing 501 is located at the rear of the base 101. The conveying roller 502 is rotatably installed inside the housing 501 through a built-in power mechanism. The C-shaped bracket 503 is fixedly installed on the inner side wall of the housing 501. Multiple sets of vision cameras 504 are arranged circumferentially on the outer side wall of the C-shaped bracket 503 to acquire multi-angle images of the workpiece during conveying.

[0076] This embodiment also includes a moving device, a conveyor frame 601, a cylinder 602, a lifting frame 603, and suction cups 604. The conveyor frame 601 is mounted on the moving device and driven by it to move horizontally. The fixed end of the cylinder 602 is mounted on the outer wall of the conveyor frame 601, while its moving end is connected to the lifting frame 603. The lifting frame 603 is slidably mounted on the conveyor frame 601. Multiple suction cups 604 are mounted on the bottom end of the lifting frame 603 and connected to an external vacuum device.

[0077] The moving device, serving as the horizontal drive unit of the conveyor frame 601, includes a guide member 701, a lead screw 702, and a motor 703. The bottom of the conveyor frame 601 is slidably mounted on the guide member 701. The lead screw 702 is rotatably mounted on the inner side wall of the guide member 701, and the conveyor frame 601 is screwed onto the lead screw 702. The motor 703 is mounted on the outer side wall of the guide member 701, and its output end is connected to the lead screw 702.

[0078] To improve the stability of the lifting movement of the support arm 303, this embodiment also provides guide grooves 801 on the outer side walls of the two sets of support arms 303 respectively, and provides a support seat 802 that slides with the guide grooves 801 on the outer side wall of the base 101. The top of the lower mold 102 is provided with a positioning shaft 901, which is used to pass through the pre-set process hole on the blank to achieve precise positioning. At the same time, the bottom of the upper mold 104 is provided with a groove corresponding to the position of the positioning shaft 901 to avoid interference when the mold is closed.

[0079] In this embodiment, the third hydraulic cylinder 302 drives the second lifting platform 301 to slide downward along the guide column 202. The second lifting platform 301 drives the two sets of support arms 303 and the first inclined block 304 fixed at its bottom to move downward synchronously. The inclined surface of the first inclined block 304 abuts against the inclined surface of the second inclined block 305 and converts the vertical movement into horizontal movement, thereby pushing the two sets of second inclined blocks 305 and the side shaping mold 106 fixedly connected to them to slide in opposite directions along the guide rail 306 to realize the lateral extrusion shaping action. When the third hydraulic cylinder 302 drives the first inclined block 304 to move upward and reset, the compressed multiple sets of first springs 309 release their elastic force and push the guide column 308 to drive the two sets of side shaping molds 106 to slide in the opposite direction and reset. During this process, the downward movement of the lower mold 102 in the flanging process compresses the telescopic column 401 and causes the second spring 402 to accumulate elastic potential energy. When the upper mold 104 returns and unloads, the second spring 402 releases energy to push the lower mold 102 to reset quickly.

[0080] After the car swing arm completes the flanging and shaping, the motor 703 in the moving device drives the lead screw 702 to rotate. The lead screw 702 drives the conveyor frame 601 and the lifting frame 603 to move horizontally above the forming station. The cylinder 602 pushes the lifting frame 603 down so that the suction cup 604 contacts and picks up the finished workpiece. Then the conveyor frame 601 moves in the opposite direction to transport the finished workpiece to the conveyor roller 502. The conveyor roller 502 rotates to send the workpiece into the detection area of ​​the C-shaped bracket 503. Multiple sets of vision cameras 504 collect images of the workpiece from different positions and send the data to the vision inspection system for analysis and comparison to complete the automatic detection and judgment of the flanging and shaping quality.

[0081] This embodiment transforms vertical drive into horizontal opposing drive through a sloping mechanism, resulting in a compact structure and good synchronization. Combined with a spring reset mechanism, it enables the rapid retraction of the side forming mold 106. Simultaneously, it integrates visual inspection and automatic loading / unloading modules, forming a fully automated closed loop from molding and shaping to inspection. Compared with existing technologies, this embodiment seamlessly connects the shaping action with the inspection process, significantly improving the overall intelligence level and production cycle of the machine. Furthermore, the introduction of visual inspection fundamentally changes the traditional quality control mode that relies on manual sampling, greatly improving the reliability and traceability of product quality.

[0082] Through the detailed description of the above embodiments, the automotive swing arm flanging and shaping machine of the present invention has the following non-obvious beneficial effects compared with the prior art:

[0083] 1. By coordinating the edge forming mold and the side forming mold, the top edge and the outer wall edge of the workpiece after flanging are simultaneously extruded and formed, which fundamentally eliminates the positioning error and uneven deformation caused by step-by-step forming and ensures the high consistency of batch products.

[0084] 2. The support components, guide components and elastic components are integrated around the base and guide column. Each functional unit is clearly hierarchical and its actions do not interfere with each other. The whole machine has a compact structure, small footprint, and is easy to lay out in an automated production line.

[0085] 3. The testing mechanism and loading / unloading moving device are connected to the main unit in a modular manner, which can be quickly disassembled or replaced according to different production needs, improving the versatility and maintainability of the equipment;

[0086] 4. By integrating a visual inspection module after the shaping process, online automatic inspection of each molded product is realized, which can promptly detect defects such as burrs, cracks, and excessive springback, ensuring that only qualified products can flow into the next process;

[0087] 5. For exposed moving parts such as the lead screw 702 and guide column 308, an accordion-style dustproof telescopic cover can be preferably installed on the outside to prevent dust and debris from entering; for the inclined block and guide rail with frequent relative movement, self-lubricating copper alloy material is used and a sealing scraper is installed, which effectively extends the maintenance cycle and the service life of the whole machine.

[0088] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions, and variations can be made to the above embodiments without departing from the principles and spirit of the present invention.
