Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically to a front support frame for a bending machine. Background Technology

[0002] As a core piece of equipment in the sheet metal processing industry, the bending machine in its standard model mainly consists of a support frame, a worktable, and a clamping plate. The front support device, an indispensable auxiliary component of the bending machine, bears the heavy responsibility of supporting the sheet metal before it is conveyed to the bending machine base. While traditional front-support devices can achieve left-right sliding adjustment via a connection between the slide rail and the front of the worktable, and can also adapt to vertical height using a screw structure, they have significant limitations in adjusting the support depth, and cannot flexibly adjust the front and rear positions according to material specifications. This deficiency is particularly prominent when handling wide materials: when the material is wide, because the front-support device cannot extend forward, the end of the material furthest from the worktable will inevitably be suspended in the air. This not only causes irregular swaying of the material during bending due to uneven force, resulting in precision defects such as bending angle deviation and crease offset, but also may lead to a risk of falling due to instability, posing a serious threat to the personal safety of operators. Traditional bending machines cannot achieve synchronous adaptation of support points when adjusting the front and rear positions. When handling heavier materials, the material's center of gravity and the force-bearing point of the support device will be significantly offset, making it difficult to keep them in a straight line. This causes the cantilever part of the front material support device to bear excessive torque and pressure. Prolonged exposure to this unbalanced stress state can easily lead to structural deformation, excessive wear or even breakage of key components, significantly reducing equipment performance and lifespan, while increasing maintenance costs and downtime, severely impacting production efficiency and operational continuity. To address this, the applicant has proposed a front support frame for bending machines, aiming to resolve the aforementioned technical challenges. Utility Model Content

[0003] The purpose of this invention is to provide a front support frame for a bending machine, solving the following technical problems: While traditional front support devices can achieve left-right sliding adjustment via a slide rail connected to the front of the worktable, and can also achieve vertical height adaptation using a screw structure, they have significant limitations in adjusting the support depth, and cannot flexibly adjust the front and rear positions according to material specifications. This defect is particularly prominent when handling wide materials: when the material width is large, because the front support device cannot extend forward, the end of the material furthest from the worktable will inevitably be suspended in the air. This not only causes irregular shaking of the material during bending due to uneven force, resulting in precision defects such as bending angle deviation and crease offset, but also may lead to a risk of falling due to instability, posing a serious threat to the personal safety of operators.

[0004] The objective of this utility model can be achieved through the following technical solutions: A front support frame for a bending machine includes two symmetrically arranged support seats. Multiple rollers are rotatably mounted on one side of each support seat via a rotating shaft. A guide rod is fixed between the two support seats. Linear bearing seats are symmetrically fitted onto the outer surface of the guide rod. A common base plate is fixedly mounted on one side of each of the two linear bearing seats. A side plate is fixedly mounted on one side of the base plate. A support bracket is slidably mounted inside the side plate. A sliding seat is fixedly mounted at the upper end of the support bracket. A support plate is slidably mounted at the upper end of the sliding seat. A through hole is formed in the middle of the support plate, and a drive assembly is disposed within the through hole. The drive assembly includes a motor fixedly installed inside the through hole, a ball screw installed on the output shaft of the motor, a slider threadedly connected to the surface of the ball screw, an auxiliary support plate fixedly installed at the upper end of the slider, and the auxiliary support plate slidably installed inside the through hole.

[0005] As a further embodiment of this utility model: the upper and lower ends of the material support plate are symmetrically provided with first U-shaped grooves, and the sliding seat is slidably engaged in the first U-shaped grooves.

[0006] As a further embodiment of this utility model: a coil is sleeved on one end of the outer surface of the optical rod, and the coil is connected to the optical rod by a screw.

[0007] As a further embodiment of this utility model, rubber pads are fitted onto the outer surfaces of both ends of the optical rod.

[0008] As a further embodiment of this utility model: a second U-shaped groove is symmetrically provided on both sides of the material support plate, and a sliding block is symmetrically slidably arranged inside the second U-shaped groove. A baffle plate is bolted to the outer side of each of the two sliding blocks.

[0009] As a further embodiment of this utility model: a telescopic cylinder is provided at the bottom end of the material support plate, and the piston rod end of the telescopic cylinder is fixedly connected to one side of the sliding seat.

[0010] As a further embodiment of this utility model: the through hole is designed to be narrower at the top and wider at the bottom, and is used to snap onto the auxiliary support plate.

[0011] As a further embodiment of this utility model: the upper surface of the material support plate is flush with the upper surface of the auxiliary support plate.

[0012] The beneficial effects of this utility model are: (1) This utility model uses a motor to drive a ball screw to move the auxiliary support plate back and forth, which can flexibly adjust the exposed length of the auxiliary support plate to adapt to materials of different widths. At the same time, the sliding adjustment of the support base can quickly match the material length requirements. This multi-dimensional adjustment design effectively solves the problem of wide materials being suspended due to the inflexible adjustment of the front and rear positions of traditional material support frames, avoids bending accuracy deviations caused by differences in material specifications, and achieves stable support for materials of different sizes and shapes.

[0013] (2) This utility model relies on the telescopic cylinder to drive the sliding seat to slide, which can accurately adjust the position of the material support bracket and ensure that the center of gravity of the material coincides with the force point of the sliding seat. Structurally, it eliminates the problem of excessive cantilever torque caused by the center of gravity offset of traditional equipment, reduces the risk of structural deformation and component wear, and extends the service life of the equipment. At the same time, the shock absorption design of the rubber pad reduces the impact of vibration on the accuracy of the equipment, and the limiting effect of the baffle plate prevents the material from slipping. Multiple structural optimizations together improve the operational safety and equipment reliability during the bending process.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0020] In the actual operation of a bending machine, the front support frame plays a crucial role, responsible for providing stable support to the material before bending, directly affecting bending accuracy and operational safety. Currently, most bending machines on the market use a traditional structural design for their front support devices: it connects to the front of the worktable via a slide rail, allowing for left-right sliding adjustment to accommodate the left-right positioning needs of materials of different widths; simultaneously, it uses a screw structure for vertical height adjustment to ensure it matches the placement height of the material. However, the front and rear positions of traditional bending machine front support frames cannot be flexibly adjusted. This deficiency is particularly pronounced when dealing with materials of different widths: when the material is wide, because the front support device cannot extend forward, the end of the material furthest from the worktable will be suspended in mid-air. This suspension not only causes the material to sway during bending, affecting bending accuracy, but also poses a risk of falling due to an unstable center of gravity, seriously threatening the personal safety of the operators. In scenarios where the front support device needs to be adjusted in position, traditional support structures cannot adjust synchronously with the position changes. When handling heavy materials, the material's center of gravity and the stress point of the support device will shift, becoming misaligned. This causes the cantilever section of the front support device to bear excessive torque and pressure, which can easily lead to structural deformation, component wear, or even breakage over time. This significantly reduces the device's performance and lifespan, and increases maintenance costs and downtime.

[0021] Therefore, this utility model addresses the aforementioned problems of the front support frame in traditional bending machines. Through an innovative structural design, it effectively solves the problems of rapid front-to-back adjustment of the front support frame, ensuring stable support for materials of different widths and weights, and avoiding suspension issues and safety hazards. The specific implementation method is as follows: Example 1: As Figure 1 , Figure 6 , Figure 7 As shown, horizontal guide grooves 24 are symmetrically arranged on the front side of the workbench panel 23. The front support frame of the bending machine includes two symmetrically arranged support seats 1. Each side of the two symmetrical support seats 1 is rotatably equipped with multiple rollers 2 via a rotating shaft. In this embodiment, there are two rollers 2. The two symmetrically arranged rollers 2 are in rolling contact with the bottom surface of the upper and lower horizontal guide grooves 24. The rollers 2 can be bearings, which act as fulcrums to support the front support device and ensure its stability. Rolling friction is used, resulting in low friction. During processing, the horizontal guide grooves 24 have high processing requirements and require good flatness. The two symmetrical supports... A light rod 3 is fixedly installed between the bases 1. The light rod 3 has a circular cross-section. A coil 4 is sleeved on one end of the outer surface of the light rod 3. The coil 4 is fixed to the light rod 3 by screws 5. The outer surface of both ends of the light rod 3 is covered with rubber pads 6. During operation, the light rod 3 may vibrate due to its own movement or external load. The rubber pads 6 have elastic deformation capability and can absorb vibration energy through their own compression or deformation, reducing the rigid impact between the light rod 3 and the support base 1, preventing vibration from being transmitted to other parts of the equipment through the support base 1, and reducing structural fatigue, noise or accuracy error caused by vibration.

[0022] Furthermore, such as Figure 1 , Figure 3As shown, linear bearing seats 7 are symmetrically fitted onto the outer surface of the smooth rod 3. The two linear bearing seats 7 are symmetrically fitted onto the outer surface of the smooth rod 3. A common floor 8 is fixedly installed on one side of the two symmetrical linear bearing seats 7. A side plate 9 is fixedly installed on one side of the floor 8. A rectangular groove 10 is opened inside the side plate 9. A material support bracket 11 is slidably fitted inside the rectangular groove 10. A limit plate 12 is fixedly installed at the horizontal end of the material support bracket 11 inside the rectangular groove 10. The limit plate 12 can slide inside the rectangular groove 10. At the same time, the width of the limit plate 12 is greater than the closing size of the rectangular groove 10 outside the floor 8. Finally, the material support bracket 11 is in a stable state where it cannot slide out of the rectangular groove 10 due to the effective limitation of the limit plate 12 during the sliding process. A sliding seat 13 is fixedly installed at the upper end of the material support bracket 11. A material support plate 14 is slidably installed at the upper end of the sliding seat 13.

[0023] Furthermore, such as Figure 2 As shown, the upper and lower ends of the material support plate 14 are symmetrically provided with first U-shaped grooves 15, and the sliding seat 13 is slidably engaged inside the first U-shaped grooves 15.

[0024] In summary, the front support frame is engaged with the front side of the worktable panel 23 by the symmetrically arranged rollers 2, and the support frame 11 can slide inside the rectangular groove 10. The support frame 11 is limited by the limiting plate 12, so that the support frame 11 cannot slide out of the rectangular groove 10 during the sliding process due to the effective limitation of the limiting plate 12.

[0025] Example 2: Based on Example 1, as follows Figure 2 As shown, the material support plate 14 has symmetrically provided second U-shaped grooves 16 on both sides. Sliding blocks 17 are symmetrically slidably arranged inside the second U-shaped grooves 16. The outer sides of the two sliding blocks 17 are connected to baffle plates 18 by bolts. The baffle plates 18 are arranged on the outer side of the material support plate 14 and can slide on the material support plate 14 to limit the side of the material and prevent the material from sliding out of the material support plate 14 from both ends.

[0026] Furthermore, such as Figure 2 , Figure 4As shown, a through hole 19 is formed in the middle of the material support plate 14. A drive assembly 20 is installed inside the through hole 19. The drive assembly 20 is used to realize the reciprocating movement of the auxiliary support plate 2004. The drive assembly 20 includes a motor 2001 fixedly installed inside the through hole 19. A ball screw 2002 is installed on the output shaft of the motor 2001. One end of the ball screw 2002 is rotatably connected to the material support plate 14 through the motor 2001. A slider 2003 is threadedly connected to the ball screw 2002. An auxiliary support plate 2004 is fixedly installed at the upper end of the slider 2003. The auxiliary support plate 2004 is slidably engaged in the through hole 19. The through hole 19 is designed to be narrower at the top and wider at the bottom, ensuring that the auxiliary support plate 2004 can be engaged when supporting materials, thereby improving the overall stability of the front support frame. Under the action of the drive component 20, the auxiliary support plate 2004 moves back and forth within the through hole 19, and the exposed length of the auxiliary support plate 2004 can be flexibly adjusted. When the material loses reliable support, it will not only cause irregular shaking due to uneven force during the bending machine's processing, directly resulting in precision defects such as bending angle deviation and crease offset, affecting the processing quality of the workpiece; but also cause the material's center of gravity to exceed the support range, forming an unstable posture, which can easily lead to a sudden fall risk.

[0027] The upper surface of the auxiliary pallet 2004 is flush with the upper surface of the material pallet 14. The flush surfaces can form a continuous and drop-free support surface, avoiding steps or gaps caused by the inconsistent heights of the two, which could lead to tilting or shaking of materials when they are placed.

[0028] Furthermore, such as Figure 5 As shown, a mounting plate 21 is fixedly installed at the bottom of the material support plate 14, and a telescopic cylinder 22 is fixedly installed at one end of the mounting plate 21. The piston rod end of the telescopic cylinder 22 is fixedly connected to one side of the sliding seat 13.

[0029] In summary, during use, the distance between the two symmetrical front support frames is quickly adjusted by the length and width of the material. The motor 2001 drives the slider 2003, which is threadedly connected to the ball screw 2002, to move back and forth. The slider 2003 drives the attached support plate 1904 to one end within the through hole 19, quickly adjusting the width of the front support frame to accommodate materials of different widths. This avoids bending accuracy deviations caused by differences in material specifications and achieves stable support for materials of different sizes and shapes. After the width is adjusted, the sliding seat 13 is driven to slide by the telescopic cylinder 22, which can precisely adjust the position of the support bracket 11, ensuring that the center of gravity of the material coincides with the force point of the sliding seat 13. Structurally, this eliminates the problem of excessive cantilever torque caused by center of gravity offset in traditional equipment, reduces the risk of structural deformation and component wear, and extends the service life of the equipment.

[0030] Example 3: Based on Examples 1 and 2, as follows... Figure 1As shown, when using the front support frame of this utility model bending machine, the front support frame can slide according to the size of the material being supported, so that the distance between the two symmetrical front support frames is adapted to the length of the material. Then, the motor 2001 drives the slider 2003, which is threadedly connected to the ball screw 2002, to move back and forth in the through hole 19. The slider 2003 drives the auxiliary support plate 2004 to move, so that the exposed length of the auxiliary support plate 2004 is adapted to the width of the material. After the width is adjusted, the telescopic cylinder 22 drives the sliding seat 13 to slide in the first U-shaped groove 15 to quickly adjust the position of the sliding seat 13, so that the center of gravity of the material coincides with the center of gravity of the sliding seat 13. If the material is a regular-shaped object with uniform material (such as a cuboid, cylinder, sphere, etc.), the position of the center of gravity can be directly calculated through geometric characteristics. After the length and width are adjusted, the material shearing work can be carried out.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
