Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, in particular to a front suspension beam support plate bending and rib pressing device. Background Art

[0002] With the rapid development of the automotive industry, the front suspension beam support plate, a crucial component of the vehicle chassis system, faces increasing challenges in terms of machining accuracy and quality, directly impacting the performance and safety of the vehicle. During production, these plates require bending and beveling to enhance their structural strength and stability. While various bending and beveling devices are currently available on the market, some technical challenges remain in their practical application.

[0003] Prior art, such as Chinese patent publication CN111496021B, discloses an adjustable-angle bending device for aluminum alloys. This device includes a bracket, a guide seat, an upper clamping plate, and a hydraulic cylinder. A guide hood with angle markings is installed on one side of the aluminum alloy sheet, and a rotating plate is installed within the hood to precisely adjust the angle. This allows for precise adjustment of the bending angle. However, this device struggles to maintain a smooth die surface curve when processing complex curved front suspension beam support plates, and its adjustment accuracy is limited.

[0004] Chinese patent publication CN112170576A describes a heavy-duty vehicle stabilizer bar bending and forming machine. The device comprises a workbench, a mold for clamping and fixing the stabilizer bar's center, a roller assembly, and a bending roller mechanism. It is capable of producing high-precision stabilizer bars in large quantities. However, the device is primarily designed for bending rod-shaped workpieces and is less suitable for plate-shaped workpieces, particularly front suspension beam support plates that require ribbed processing.

[0005] Chinese patent publication CN212042103U discloses a bending machine for excavator door panels. The machine, consisting of a base, a body, struts, a mounting frame, and a resistor plate, can rapidly bend entire steel plates, minimizing damage from repeated machining. However, the machine lacks flexibility when performing precise rib bending operations, making it difficult to meet the complex machining requirements of front suspension beam support panels.

[0006] Chinese patent document CN116493448B introduces a metal part pressing and bending device for door and window manufacturing. The device includes a base, a support plate, a top plate, a hydraulic telescopic rod and a bending device, etc., which can adjust different angles without changing the mold.

[0007] Chinese patent publication CN113263081A discloses a metalworking device and bending method for adjusting bending angles. The device, which includes a base, support plate, control box, motor, and sliding plate, facilitates observation and adjustment of metal bending, increasing metal stability during operation. However, the device lacks the ability to control the smoothness of the die surface curve during precise beading operations.

[0008] In summary, the bending and beading devices in the prior art have the following deficiencies when processing front suspension beam support plates: First, it is difficult to achieve precise adjustment of the bending and beading process, especially when processing complex curved surfaces, the adjustment accuracy is limited; second, the smoothness of the mold surface curve is insufficiently controlled, which easily leads to a decrease in the surface quality of the workpiece; third, most existing devices are single-function designs, which make it difficult to simultaneously meet the dual needs of bending and beading; fourth, there is a lack of effective protection measures for the surface quality of the workpiece, which easily causes damage to the workpiece during processing. Therefore, there is an urgent need to develop a front suspension beam support plate bending and beading device that can precisely adjust and ensure the smoothness of the mold surface curve, so as to improve the processing quality and efficiency of the front suspension beam support plate. Summary of the Invention

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example:

[0034] like Figure 1-6 As shown, an embodiment of the present invention provides a front suspension beam support plate bending and beading device, including a support base 1, the upper side wall of the support base 1 is fixedly connected to four groups of support hydraulic cylinders 2, the tops of the four groups of support hydraulic cylinders 2 are fixedly connected to a support top seat 3, the lower side wall of the support top seat 3 is fixedly connected to an upper mold base 302, the lower side wall of the upper mold base 302 and the upper side wall of the support base 1 are both installed with a processing mold base 5, the support hydraulic cylinder 2 can drive the support top seat 3 to move up and down, and will push the sub-module 502 to move downward, thereby applying pressure to the support plate main body 4 placed below to achieve bending or beading function.

[0035] Each processing die base 5 is composed of several submodules 502, each of which is slidably connected to adjacent submodules 502. A U-shaped resistor plate 5023 is fixedly connected to the front sidewall of each submodule 502, or the support base 1, and the inner sidewall of the upper die base 302. Two conductive contacts 5027 are fixedly connected to the rear sidewall of each submodule 502.

[0036] The outer sidewalls of the processing die base 5 are all mounted with die sleeves 501, which are made of highly elastic material. The highly elastic material can provide a good buffering effect during processing, reduce vibration during processing, and make the die surface curve of the processing die base 5 smoother when bending or ribbed.

[0037] Several electric push rods 303 are mounted on the upper inner wall of the upper die base 302. The output end of each electric push rod 303 is fixedly connected to the upper side wall of the sub-module 502 inside the upper die base 302. The electric push rods 303 can precisely control the position and movement of the sub-module 502, thereby adjusting the forming die surface of the upper processing die base 5.

[0038] Several internal hydraulic cylinders 102 are mounted on the lower inner wall of the support base 1. The output end of each internal hydraulic cylinder 102 is fixedly connected to the lower side wall of the submodule 502 within the support base 1. The internal hydraulic cylinders 102 provide a strong and stable thrust to control the up and down movement of the bottom submodule 502, thereby adjusting the forming surface of the lower processing die holder 5. The cooperation between the upper forming surface and the lower processing die holder 5 enables bending or rib-forming of the support plate body 4.

[0039] Each U-shaped resistor plate 5023 cooperates with the conductive contact 5027 on the side wall of the adjacent sub-module 502. The outer wall of the U-shaped resistor plate 5023 is installed with a graphite layer. The cooperation between the U-shaped resistor plate 5023 and the conductive contact 5027 forms a circuit connection. The current measurement module can determine the length of the U-shaped resistor plate 5023 connected to the current measurement loop through the magnitude of the current in the current measurement loop, thereby determining the height difference between adjacent sub-modules 502, thereby facilitating the precise adjustment of the distance between the sub-modules 502, and thus adjusting the molding die surface.

[0040] The front sidewalls of the submodules 502 are provided with front rails 5022 and front sliders 5021, while the rear sidewalls of the submodules 502 are provided with rear rails 5028 and rear sliders 5029. The front rails 5022 cooperate with the rear sliders 5029, while the front sliders 5021 cooperate with the rear rails 5028. This design of rails and sliders forms a sliding connection mechanism between the submodules 502, enabling adjacent submodules 502 to move smoothly along the predetermined track, ensuring the positional accuracy and motion stability of the submodules 502 during processing and preventing mutual interference between the submodules 502.

[0041] A limit frame 101 is mounted on the upper sidewall of the support base 1. The support plate body 4 is positioned between the support base 1 and the limit frame 101. A fixed top frame 301 is mounted on the upper sidewall of the support top seat 3, interfitting with the support plate body 4. The limit frame 101 and the fixed top frame 301 work together to accurately position the support plate body 4, preventing displacement during machining and ensuring machining accuracy. The fixed top frame 301 also applies appropriate pressure to the support plate body 4, maintaining stability during machining.

[0042] The submodule 502 within the upper die base 302 is provided with a sliding inner groove 5024. A vertical guide rod 5025 is fixedly connected to the inner portion of the sliding inner groove 5024. The outer wall of the guide rod 5025 is provided with a plurality of buffer plates 5026. The buffer plates 5026 are made of stainless steel and have a clearance fit with the guide rod 5025. The design of the guide rod 5025 and the buffer plates 5026 provides vertical guidance and buffering for the submodule 502, ensuring that the submodule 502 remains stable and does not deviate during its upward and downward movement. The buffer plates 5026 made of stainless steel have excellent wear resistance and elasticity, which can reduce the impact force during the movement of the submodule 502 and extend the service life of the device.

[0043] During operation, first place the support plate body 4 to be processed between the limit frames 101 on the support base 1, and then drive the support top seat 3 to descend through the support hydraulic cylinder 2, so that the upper mold base 302 is close to the support base 1. The electric push rod 303 and the internal hydraulic cylinder 102 respectively control the movement of the upper mold base 302 and the sub-module 502 inside the support base 1, and bend and press the support plate 4 according to the shape requirements. During the processing, the U-shaped resistor plate 5023 is connected to the circuit through the conductive contact 5027, so as to adjust the relative height between the measurement sub-modules 502. The sliding connection mechanism between the sub-modules 502 ensures that each sub-module 502 can work in coordination and accurately realize complex bending and pressing shapes. After the processing is completed, the support hydraulic cylinder 2 drives the support top seat 3 to rise and take out the processed support plate body 4. When bending the support plate main body 4, there is no need to fix the fixed top frame 301 to fix the two ends of the support plate main body 4, so that the two processing mold bases 5 support the plate main body 4 to bend and deform as a whole; when pressing the ribs of the support plate main body 4, it is necessary to install the fixed top frame 301 on the fixed top seat 3, so that the fixed top frame 301 fixes the support plate main body 4 during the falling process of the support top seat 3, and then the electric push rod 303 pushes the single sub-module 502 to press the ribs, so that the support plate main body 4 is partially plastically deformed to form raised or recessed ribs.

[0044] The circuit control part of the device is centered on the PLC. The PLC input is connected to the current measurement module, limit switch, etc., and the output is connected to the electric push rod driver, hydraulic cylinder solenoid valve, etc. The current measurement module is connected in series in the loop formed by the U-shaped resistor plate 5023 and the conductive contact 5027 of the sub-module 502, measuring the current in real time and transmitting it to the PLC. The PLC calculates the connection length of the resistor plate based on the current, determines the height difference of the sub-module 502, and accurately adjusts the position. The PLC controls the electric push rod 303 and the hydraulic cylinder solenoid valve to achieve precise movement of the sub-module 502 and form a processed surface. The circuit contains short-circuit, overload, and limit protection, and cuts off the power supply and alarms in the event of an abnormality. The control panel has an emergency stop button, which can directly cut off the power source in an emergency. This design can ensure the precise movement of the sub-module 502 and guarantee processing accuracy, while also protecting the circuit in all directions, making the equipment more reliable.

[0045] Through the flexible combination and precise control of the submodules 502, the device can achieve high-precision bending and beading processing of the front suspension beam support plate, improve processing efficiency and product quality, and meet the high-precision processing requirements of the automobile manufacturing industry for the front suspension beam support plate.
