[0010] Preferably, the transmission arc-shaped gear rack and the adjusting gear are both made of alloy steel and are hardened to a surface hardness of not less than HRC55, so as to ensure wear resistance and service life during high-frequency bending operations.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention achieves independent adjustment in four directions through four sets of independent linear guide rail pairs. Different sheet materials have different lengths, thicknesses, and bending positions. Therefore, the equipment must first be able to flexibly adjust the spatial position of the material support panel. Through four sets of independent guide rails, it can achieve multi-directional adjustment in the left and right, up and down, and front and back directions. The equipment can quickly adapt to sheet materials of different lengths, thicknesses, and bending positions. Operators only need to simply adjust the position of each guide rail to complete the changeover in a few minutes without disassembly and reassembly. Compared with traditional fixed material support racks, it significantly shortens the changeover time and improves equipment utilization.

[0022] 2. The servo motor of this invention directly drives the gear to mesh with the arc-shaped gear rack, resulting in fast transmission response. It can keep pace with the downward speed of the bending machine slider. Combined with the high-precision guidance of the positioning slide rail and the first linear guide rail, the flipping angle of the material support table panel is accurate and easy to adjust, ensuring that the bending angle of each piece of sheet metal to be bent is consistent. Through the sliding positioning provided by the positioning slide rail and the first linear guide rail, the table can automatically adjust its position along the slide rail path while swinging, improving the support effect. The sliding between the table and the sheet metal is reduced, thereby avoiding scratches on the sheet metal. When the sheet metal squeezes or stretches the material support table panel, the material support table panel can automatically fine-tune its position along the first linear guide rail, adaptively adjusting without the need for additional sensors and drive motors, resulting in rapid response and high reliability.

[0023] 3. This invention places the sheet metal on the support platform and pushes it into the bending machine. The subsequent flipping and support are all completed automatically by the equipment. The worker's hands are always away from the mold area, which effectively reduces the risk of safety accidents. In addition, this equipment adopts a modular design with linear guide rails connecting the main frame, adjustment frame, movable support, and support platform. It is easy to disassemble and assemble. Only cleaning the guide rails and adding grease to the gear rack are required. There is no need for complicated hydraulic system maintenance or electrical calibration, which reduces the total life cycle cost of the equipment. It is easy to maintain and operate.

[0032] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] To address the issue that existing follow-up material support devices are limited by material and operational requirements, making it difficult to adjust the actual working position and thus affecting work efficiency, please refer to [the relevant documentation / reference]. Figure 1 - Figure 7 This embodiment provides the following technical solution:

[0034] The following front material support device for bending auxiliary sheet metal of bending machine includes a protective shell 3, a material support table panel 1 and a main frame 4. The protective shell 3 is set at the front end of bending machine, the material support table panel 1 is set on the lower crossbeam 2 of bending machine, and the main frame 4 is installed below the material support table panel 1.

[0035] Please see Figure 1 , Figure 2 , Figure 3 A transmission arc-shaped gear rack 101 is installed at the lower end of the material support panel 1. A movable support 6 is provided below the material support panel 1. An adjustment frame 601 is installed at the front end of the movable support 6. The front end of the main frame 4 is connected to the outer rail 5 of the bending machine. The main frame 4 is used to adjust the position of the protective shell 3 of the equipment. Adjustable support feet 7 are installed on both sides of the lower end of the adjustment frame 601. A servo motor 8 for driving the transmission arc-shaped gear rack 101 is installed at the upper end of the movable support 6.

[0036] In some embodiments, the radius of the arc of the transmission arc toothed rack 101 is set according to the theoretical motion trajectory of the lower surface of the sheet during bending, so that the material support plate 1 can maintain close contact with the lower surface of the sheet at different bending angles.

[0037] In some embodiments, the tooth module of the transmission arc-shaped tooth row 101 is 1.5mm to 3mm, and the number of teeth is not less than 30, so as to ensure the smoothness of meshing transmission and load-bearing capacity.

[0038] Servo motor 8 is an absolute encoder servo motor with a response time of no more than 20ms to ensure real-time synchronization with the downward speed of the bending machine slide.

[0039] In some embodiments, the transmission arc-shaped gear rack 101 and the adjusting gear 801 are both made of alloy steel and are hardened to a surface hardness of not less than HRC55, so as to ensure wear resistance and service life during high-frequency bending operations.

[0040] By placing the sheet metal on the support plate 1 and pushing it into the bending machine, the subsequent flipping and support are completely completed automatically by the equipment. The worker's hands are always away from the mold area, effectively reducing the risk of safety accidents. In addition, the equipment is connected by linear guide rails between the main frame 4, the adjustment frame 601, the movable support 6, and the support plate 1. It has a modular structure, which is easy to disassemble and assemble. Only the guide rails need to be cleaned and grease added to the gear rack. There is no need for complicated hydraulic system maintenance or electrical calibration, which reduces the total life cycle cost of the equipment. It is easy to maintain and operate.

[0041] Please see Figure 3 - Figure 6 This equipment achieves independent adjustment of the material support panel 1 in multiple directions through the cooperation of multiple sets of linear guide rail pairs.

[0042] (i) The entire machine moves horizontally. The lower crossbeam 2 of the bending machine is fixed at the feed inlet of the bending machine. A limit plate 201 is installed at the rear end of the lower crossbeam 2 of the bending machine. The limit plate 201 is used to limit the position of the bending sheet. The lower end face of the material support plate 1 abuts against the lower crossbeam 2 of the bending machine. The front end of the main frame 4 is fixedly installed with a second linear guide rail 401. The second linear guide rail 401 is horizontally slidably connected to the outer rail 5. Through this sliding fit, the entire equipment can move left and right along the length of the bending machine to adapt to the processing needs of sheet metal of different widths.

[0043] (ii) Front and rear telescopic adjustment: The lower end of the equipment protective shell 3 is fixedly connected to the mounting bracket 301, and the upper end of the mounting bracket 301 is provided with a sliding seat 302. The bottom of the movable bracket 6 is fixedly connected to the fourth linear guide rail 604. The movable bracket 6 is horizontally slidably connected to the sliding seat 302 through the fourth linear guide rail 604. Through this sliding cooperation, the movable bracket 6 can telescopically extend and retract in the horizontal direction relative to the equipment protective shell 3 to adapt to the needs of different length plates and different bending line positions.

[0044] (iii) Double-layer vertical adjustment: The rear end of the main frame 4 is fixedly connected to the third linear guide rail 402. The main frame 4 is vertically slidably connected to the front end of the adjustment frame 601 through the third linear guide rail 402. The rear end of the adjustment frame 601 is fixedly connected to the fifth linear guide rail 605. The adjustment frame 601 is vertically slidably connected to the movable bracket 6 through the fifth linear guide rail 605.

[0045] Through the aforementioned double-layer vertical sliding structure, the adjusting frame 601 relative to the main frame 4 and the movable support 6 relative to the adjusting frame 601 can slide independently in the vertical direction. The superposition of the strokes of the two layers of vertical sliding pairs enables a larger vertical adjustment range under the condition of limited overall equipment height. Large-amplitude and rapid height adjustment is achieved through the third linear guide rail 402, and small-amplitude fine correction is achieved through the fifth linear guide rail 605, thus taking into account both the adjustment range and adjustment accuracy requirements.

[0046] Specifically, four sets of independent linear guide rails enable independent adjustment in four directions. Different sheet materials have different lengths, thicknesses, and bending positions. Therefore, the equipment must first be able to flexibly adjust the spatial position of the material support panel 1. Through four sets of independent guide rails, it can achieve multi-directional adjustment in the left and right, up and down, and front and back directions. The equipment can quickly adapt to sheet materials of different lengths, thicknesses, and bending positions. Operators only need to simply adjust the position of each guide rail to complete the changeover in a few minutes without disassembly and reassembly. Compared with traditional fixed material support racks, this shortens the changeover time and improves equipment utilization.

[0047] Please see Figure 5 , Figure 6 , Figure 7The lower end of the material support panel 1 is fixedly connected to a positioning slide rail 103, and the upper end of the adjustment frame 601 is fixedly connected to a bearing seat 603. A rotating block 102 is rotatably connected to the bearing seat 603, and a first linear guide rail 104 is installed on the rotating block 102.

[0048] In some embodiments, the rotating block 102 is fixedly connected to the first linear guide rail 104, and the first linear guide rail 104 is linearly slidably connected to the positioning slide rail 103. The positioning slide rail 103 and the first linear guide rail 104 are used to limit the range of motion of the material support panel 1.

[0049] In some embodiments, the mounting angle of the positioning slide rail 103 relative to the material support panel 1 and the mounting angle of the first linear guide rail 104 relative to the rotating block 102 can be adaptively adjusted according to the plate thickness range and bending angle range under different application conditions to obtain the optimal composite motion trajectory.

[0050] In some embodiments, a drive shaft 105 is fixedly connected inside the rotating block 102, and both ends of the drive shaft 105 pass through the bearing seat 603 and are rotatably connected to the bearing seat 603.

[0051] The movable support 6 is fixedly connected to a fixed plate 602 at its rear end. The servo motor 8 is fixedly connected to the movable support 6 through the fixed plate 602. The output end of the servo motor 8 is fixedly connected to the adjusting gear 801. The adjusting gear 801 is meshed with the outer ring of the transmission arc-shaped gear rack 101.

[0052] In this embodiment, after receiving the synchronization signal of the bending machine slider moving downward, the servo motor 8 drives the adjusting gear 801 to rotate. Since the adjusting gear 801 meshes with the transmission arc-shaped gear rack 101, the rotational motion of the gear is converted into the power to push the material support panel 1 to swing around the transmission shaft 105. At the same time, since the lower end of the material support panel 1 is slidably connected to the first linear guide rail 104 on the rotating block 102 through the positioning slide rail 103, the material support panel 1 can also slide radially relative to the rotating block 102 along the first linear guide rail 104 while swinging.

[0053] In fact, the actual movement of the material support panel 1 during the bending process is a combination of oscillation around the transmission shaft 105 and sliding along the first linear guide rail 104.

[0054] During the bending process, when the sheet material is squeezed or stretched against the support table panel 1, the support table panel 1 can automatically adjust its position along the first linear guide rail 104, slide outward to compensate for the outward movement of the sheet material, or slide inward to avoid excessive pushing of the sheet material, thus achieving passive adaptive adjustment. No additional sensors and drive motors are required, and the response is rapid and the reliability is high.

[0055] In some embodiments, the first linear guide 104, the second linear guide 401, the third linear guide 402, the fourth linear guide 604, and the fifth linear guide 605 are all precision ball linear guides with a precision grade of not less than P, in order to ensure the guiding accuracy and rigidity of each motion pair.

[0056] Specifically, the servo motor 8 directly drives the gear 801 to mesh with the arc-shaped gear rack 101, resulting in fast transmission response and synchronization with the downward speed of the bending machine slider. Combined with the high-precision guidance of the positioning slide rail 103 and the first linear guide rail 104, the flipping angle of the material support panel 1 is precise and easy to adjust, ensuring consistent bending angles for each piece of sheet metal. The sliding positioning provided by the positioning slide rail 103 and the first linear guide rail 104 allows the table to automatically adjust its position along the slide rail path while swinging, improving support and reducing slippage between the table and the sheet metal, thus preventing scratches. When the sheet metal compresses or stretches the material support panel 1, the panel 1 can automatically fine-tune its position along the first linear guide rail 104, adaptively adjusting without the need for additional sensors or drive motors, resulting in rapid response and high reliability.

[0057] Please see Figure 6 The adjustable support foot 7 has an adjusting wheel 701 installed at its lower end and a lifting bracket 702 installed at its upper end. The lifting bracket 702 and the adjusting wheel 701 are connected by a bevel gear and a lead screw.

[0058] When the operator rotates the adjusting wheel 701, the horizontal rotational motion is transmitted to the lead screw through the bevel gear transmission. The rotational motion of the lead screw is converted into the vertical lifting motion of the lifting bracket 702. The lead screw transmission has a self-locking characteristic. After the adjustment is completed, the height of the lifting bracket 702 will not change automatically due to equipment vibration or the weight of the sheet material, thus ensuring the stability of long-term operation.

[0059] Specifically, the adjustable support feet 7 use bevel gears and lead screws for high precision adjustment. The lead screws also have self-locking characteristics, ensuring that the height and level of the equipment will not drift under repeated loading of several tons of sheet metal, thus guaranteeing long-term consistency. All four sets of linear guide rail pairs are precision sliding fits with small clearances and good rigidity, resulting in minimal deformation when subjected to the overturning moment generated by the weight of the sheet metal.

[0060] Working Principle: During operation, the operator first makes initial adjustments to the equipment based on the dimensions of the sheet metal to be bent. Through the sliding engagement of the second linear guide 401 and the outer rail 5, the entire equipment is moved along the length of the bending machine to a position matching the width of the sheet metal. Through the sliding engagement of the fourth linear guide 604 and the sliding seat 302, the front-to-back position of the movable support 6 is adjusted so that the initial support point of the material support panel 1 is aligned with the bending line of the sheet metal. Through the vertical sliding engagement of the third linear guide 402 and the front end of the adjusting frame 601, and the vertical sliding engagement of the fifth linear guide 605 and the movable support 6, the height of the material support panel 1 is adjusted in two layers to match the height of the lower crossbeam 2 of the bending machine. By rotating the adjusting wheel 701, the equipment is finely leveled using bevel gears and a lead screw drive to ensure the equipment is in a horizontal and stable working position. Adjustment is then complete. Afterwards, the sheet metal is placed on the support plate 1 and pushed into the feed port of the bending machine along the lower crossbeam 2 until the edge of the sheet metal abuts against the limiting plate 201, completing the feeding and positioning. After the bending machine is started, the slider moves down to bend the sheet metal. The servo motor 8 receives the synchronization signal of the bending machine and drives the adjusting gear 801 to rotate. The adjusting gear 801 pushes the transmission arc-shaped gear row 101, causing the support plate 1 to swing around the transmission shaft 105. The support plate 1 slides automatically in the radial direction while swinging through the sliding cooperation between the positioning slide rail 103 and the first linear guide rail 104, so as to adapt to the actual position change of the lower surface of the sheet metal during the bending process. When changing to a different specification of sheet metal, the operator only needs to repeat the operation of the initial adjustment stage above, and quickly adjust the support plate 1 to the new working position through each linear guide rail pair to start a new round of processing without disassembly and reassembly.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention.
