Description

Technical Field

[0001] This invention relates to the field of plate rolling machine technology, and in particular to an auxiliary device for plate processing. Background Technology

[0002] In the process of rolling sheet metal into cylindrical or curved components, it is usually necessary to rely on a three-roll plate rolling machine or a special plate rolling fixture to gradually shape the material through multiple feeds and repeated rolling. In existing equipment, the position of the rolling rollers is mostly fixed or achieved through coarse adjustment, which makes it difficult to accommodate the requirements of sheet metals of different thicknesses and widths. When it is necessary to change the plate diameter or adapt to different sheet metals, it is often necessary to loosen the fasteners multiple times and manually move the support mechanism, which is labor-intensive. Moreover, the support mechanism lacks reliable guidance during movement, which can easily cause shaking and jamming, affecting the adjustment accuracy and repeatability of the roller spacing.

[0003] On the other hand, when feeding the sheet material to be rolled into the three-roller area, it is usually pushed by workers by hand or placed on a simple platform. Under the action of gravity and friction, the front end of the sheet material is prone to tilting up, shifting, or even leaving the support surface, which makes it difficult to enter between the rolls smoothly. In severe cases, it may also interfere with the edge of the rolls, causing scratches, dents, or poor rolling of the sheet material. The existing sheet material feeding structure is mostly a fixed ramp, which lacks adjustable guidance for the feeding angle and sliding path, and also lacks a special structure for limiting and correcting the posture of different sheet material specifications. The overall rolling efficiency and product consistency need to be improved.

[0004] Therefore, how to provide a sheet metal processing auxiliary equipment with a reasonable structure, adjustable support position, easily adjustable roller height and spacing, and combined with board entry guidance and limiting functions, so as to reduce the intensity of manual operation and improve the forming quality and production efficiency of sheet metal, has become one of the technical problems that urgently need to be solved in this field.

[0005] Therefore, we propose an auxiliary equipment for sheet metal processing to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to overcome the problems of unstable board feed, difficulty in controlling the rolling trajectory, and poor versatility of different specifications of boards during the existing board rolling and arc rolling processes, and to provide a board processing auxiliary device with simple structure, convenient adjustment, stable guidance and adaptability to multiple specifications of boards.

[0007] To achieve the above object, a sheet processing auxiliary device of the present invention adopts the following technical solution: The sheet processing auxiliary device includes support plates A and B arranged oppositely, with a sheet rack provided between the two. A roller A, which serves as a driving or driven roller, is rotatably provided on the sheet rack. A support is provided on one side of the sheet rack, and a roller B and a roller C are respectively installed on the support through a sliding adjustment member, so that the roller A, the roller B, and the roller C are arranged in a "pin" shape in space. One end of the roller is mutually传动连接 (driven and connected) with a chain mechanism through a sprocket wheel, and is driven by a servo motor to achieve synchronous and同向转动 (same-direction rotation) of the three rollers, thereby forming clamping and rolling channels that act in sequence between the roller B and the roller C, and between the roller A and the roller B, so that the sheet is gradually rolled into an approximately complete cylindrical shape along a predetermined path.

[0008] To achieve adjustable and stable positioning of the support relative to the sheet rack, inner sliding grooves extending along the length direction are provided on the opposite inner side walls of the sheet rack, and tooth blocks are also provided on the inner side walls. A fixing block A is fixed on the sheet rack, and an adjusting rod A is rotatably connected in the fixing block A. The support includes a horizontally connected support portion and vertical support portions located at both ends of the horizontally connected support portion. An adjusting hole is provided through the middle of the horizontally connected support portion. The horizontally connected support portion is sleeved on the adjusting rod A through the adjusting hole and can slide relative to the sheet rack; there is a threaded fit between the adjusting rod A and the adjusting hole. By rotating the adjusting rod A, the horizontally connected support portion is driven to move along the length direction of the sheet rack, thereby achieving continuous adjustment of the distance between the entire support and the roller A to adapt to different rolling radii and sheet thicknesses.

[0009] To improve the smoothness of the support movement process, multiple pulleys are provided at positions near the bottom of both ends of the horizontally connected support portion. The pulleys are in rolling fit within the inner sliding grooves, making the support more reliable during adjustment and avoiding shaking or jamming; at the same time, a linkage rod is also rotatably provided through the middle of the horizontally connected support portion. Stable gears meshing with the tooth blocks are respectively fixed at both ends of the linkage rod. The stable gears roll along the tooth surface of the tooth blocks to guide the movement of the horizontally connected support portion, enabling the support to have both rolling guidance and gear meshing guidance when moving on the sheet rack, further improving the linearity and stability of the adjustment process.

[0010] Sliding ports extending vertically are provided on both vertical support portions of the support. A pair of sliding convex portions are respectively formed on the opposite surfaces on both sides of the vertical support portions; The sliding adjustment member includes a sliding block slidably installed in the sliding ports. A sliding sleeve port matching the vertical support portion is provided on the sliding block, enabling the sliding block to slide up and down along the vertical support portion and be locked at a specified height position through a bolt. Both ends of the roller B and the roller C are rotatably connected to the corresponding sliding blocks, so that by adjusting the height of the sliding blocks, the installation heights of the roller B and the roller C and the distance between them can be changed to adapt to sheets of different thicknesses and widths, and the rollers can still rotate freely after the height adjustment.

[0011] To achieve precise and labor-saving adjustment of the height of the sliding block, the sliding adjustment component also includes a fixed block B fixed on the sliding block and an adjusting rod B that passes through the fixed block B and is threadedly connected to it. The end of the adjusting rod B is rotatably connected to a connecting block, which is fixed to the end of the sliding protrusion, so that the adjusting rod B is arranged parallel to the vertical support. By rotating the adjusting rod B with a tool, the fixed block B and the sliding block can be driven to move up and down slightly along the sliding opening by means of thread transmission. After the sliding block is adjusted to the predetermined position, the sliding block is locked and fixed to the vertical support by bolts, so that the vertical and spacing adjustments of the rollers B and C are both precise and reliable.

[0012] To improve the feeding posture and edge guidance of the sheet metal during the rolling process, this invention provides a guide structure on the outer side of the relatively arranged sliding protrusions: a guide plate facing the winding roller A is bolted to one side of the sliding protrusion, the edge of the guide plate is inclined and close to the outer circle of the winding roller A, and is used to guide the sheet metal as it moves upward from between the winding rollers B and C into the space between the winding rollers A and B; guide members are installed on the paired sliding protrusions on the other side, each guide member including a guide plate B and a guide plate C screwed to it, the opposite sides of the two guide plates C are also inclined and close to the surfaces of the winding rollers B and C, clamping and limiting the edge of the sheet metal when it first enters the gap between the winding rollers B and C, preventing the sheet metal from shifting, warping or running off-center, and realizing multi-level guidance and limiting of the sheet metal in the rolling path.

[0013] To further improve the feeding process of the sheet material and reduce the intensity of manual feeding, a feeding structure is provided between the support plates B. The feeding structure includes a placement plate rotatably connected between the two support plates B via a flip shaft. A manual crank is provided at the end of the flip shaft, allowing the operator to adjust the placement plate between different tilt angles by turning the crank and locking the placement plate at the target angle using fasteners. Limiting rollers A and B, arranged along the width direction, are provided on the placement plate. The limiting rollers are rotatably connected to the placement plate and are used to support and limit the upper surface of the sheet material as it slides downwards, preventing the front end of the sheet material from warping or the entire sheet material from slipping out of control.

[0014] To ensure the adjustable flipping angle and reliable locking of the placement plate, an arc-shaped movable opening extending along the flipping trajectory is provided on the support plate B. The end shaft of the limiting roller A extends through the side edge of the placement plate into the movable opening, and a positioning plate is rigidly connected to its outer end. The positioning plate fits against the outer side of the support plate B. When the placement plate flips, the end of the limiting roller A slides within the movable opening, and the positioning plate rotates to the new position. Then, the positioning plate is fixed to the support plate B with bolts, thus locking the spatial posture of the placement plate and ensuring the stability of the plate feeding angle during long-term operation.

[0015] Preferably, additional limiting components are also arranged on the placement plate. The limiting components include mounting blocks A installed on both sides of the placement plate, a connecting frame bridging between the two mounting blocks A, and a pair of mounting blocks B installed at the bottom of the connecting frame. A limiting roller C is rotatably connected between the two mounting blocks B. The limiting roller C is arranged in the area between the limiting roller B, the winding roller B, and the winding roller C. When the sheet slides downward along the placement plate under its own weight, its front end abuts against the lower arc surface of the limiting roller C and is guided into the space between the winding roller B and the winding roller C, enabling the leading edge of the sheet to smoothly transition and avoiding direct collision with the winding rollers, thus improving the smoothness and safety of the feeding process.

[0016] With the above structure, through the coordinated cooperation of the plate frame, adjustable brackets, multiple winding rollers arranged in a "pin" shape, and the multi-stage guiding, limiting, and sheet-feeding structures, the present invention enables the sheet to complete the whole process from sheet-feeding, guiding, clamping to gradually being wound into a cylinder under the combined action of its own gravity and the driving winding rollers. It is not only convenient for fine adjustment according to the thickness, width of the sheet and the target curling diameter, but also significantly improves the winding stability and operation safety, and is suitable for popularization and application in various sheet winding processing occasions.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, the adjustment of the bracket position is stable and reliable, facilitating adaptation to different sheet rolling specifications; by providing inner chutes and tooth blocks on both sides of the plate frame, and arranging pulleys at the bottom of the transverse support part of the bracket, a linkage rod, and a stable gear meshing with the tooth blocks, when the bracket moves along the length direction of the plate frame under the drive of the adjusting rod, on the one hand, it realizes low-resistance sliding under the rolling guiding effect of the pulley and the inner chute, and on the other hand, it realizes stable guiding under the meshing effect of the stable gear and the tooth block, significantly improving the stability and smoothness of the bracket adjustment process and facilitating rapid adjustment of the winding roller spacing according to the sheet width and rolling diameter.

[0018] 2. In the present invention, the height and spacing of the winding rollers can be finely adjusted, and the sheet rolling forming consistency is good; a sliding port and a sliding convex part are provided on the vertical support part. The sliding adjustment part includes a sliding block sleeved on the vertical support part, a fixed block B and an adjusting rod B connected to the sliding block. A sliding sleeve port is opened on the sliding block to wrap and guide the vertical support part. The adjusting rod B drives the sliding block to move on the vertical support part through screw transmission; both ends of the winding roller B and the winding roller C are rotatably connected to the sliding block. Thus, the height positions of the winding roller B and the winding roller C relative to the winding roller A and the relative spacing between the three can be continuously adjusted, which can not only adapt to sheets of different thicknesses and widths, but also facilitate obtaining the target bending radius and cylindricity, improving the rolling forming accuracy and consistency.

[0019] 3. In the present invention, the plate inlet guiding and limiting structure cooperate to improve the feeding efficiency and reduce the warping of the plate. A rotatable placing plate is arranged between two support plates B. A limiting roller A and a limiting roller B are rotatably installed on the placing plate, and the angle of the placing plate can be adjusted through a turning shaft. The two ends of the limiting roller are locked in position by cooperating with the arc-shaped movable openings and positioning pieces on the support plate, enabling the plate to reliably slide along the placing plate under the action of gravity towards the roller inlet, avoiding the plate leaving the placing plate and shifting during the sliding process. A limiting component is further arranged on the placing plate. The limiting roller C is arranged between the limiting roller B and the roller group, and together with the guiding plate and guiding component on the same side, forms multi-stage guiding and limiting, enabling the plate to maintain a reasonable posture when entering between the roller B and the roller C, reducing the risks of warping, jamming, and scratching, and improving the smoothness of plate inlet.

[0020] 4. The overall structure of the present invention is compactly arranged, reducing the manual operation intensity and improving the rolling efficiency of the plate. By integrating the "pin" - shaped arranged rollers, adjustable brackets, sliding adjustment components, and plate inlet structure into the same plate frame and support plate system, and cooperating with the servo motor drive and sprocket chain drive, the three rollers rotate synchronously, greatly reducing the workload of manually pushing and pulling the plate and repeatedly adjusting the position. Through the combination of the structural limiting and guiding components, the rework and debugging time of the plate are reduced, improving the overall rolling efficiency and equipment applicability of the equipment, and it is suitable for popularization and use in the plate rolling station or special plate rolling tooling.

[0027] Reference Figure 1-6, A sheet processing auxiliary device, including two support plates A15 and two support plates B71. There is a plate rack 1 between the support plate A15 and the support plate B71. A winding roller A2 is rotatably provided on the plate rack 1, and a support 3 is provided on the plate rack 1 and located on the side of the winding roller A2. In this way, the support 3 and the winding roller A2 are arranged side by side on the plate rack 1. On the support 3, a winding roller B4 and a winding roller C5 are provided through a sliding adjustment member 6. The winding roller A2, the winding roller B4 and the winding roller C5 are arranged in a "pin" shape. One ends of the winding roller A2, the winding roller B4 and the winding roller C5 are传动连接 by a sprocket and a chain in the prior art, and the driving force comes from a servo motor in the prior art. The servo motor can be arranged at the other end of the winding roller A2, the winding roller B4 or the winding roller C5 according to the actual situation. In this way, after the servo motor is started, the winding roller A2, the winding roller B4 or the winding roller C5 rotates, and then under the transmission cooperation of the sprocket and the chain, the winding roller A2, the winding roller B4 and the winding roller C5 arranged in a "pin" shape rotate in the same direction at the same time; When rolling the sheet, one side of the sheet enters between the winding roller B4 and the winding roller C5, then comes out between the winding roller A2 and the winding roller B4, and then rotates to cover the outside of the winding roller B4 and tends to between the winding roller B4 and the winding roller C5 to roll into an approximately complete cylinder shape. Finally, the sheet rolled into an approximately cylindrical shape is taken off for subsequent operations.

[0028] Refer to Figure 1-6 , A sheet processing auxiliary device, inner sliding grooves 11 are provided on the opposite inner walls of the plate rack 1, and tooth blocks 12 are provided on both sides of the plate rack 1. A fixed block A13 is provided on the plate rack 1, and an adjusting rod A14 is rotatably connected in the fixed block A13. The support 3 includes a horizontally supporting portion 31 and a vertically supporting portion 32 connected as a whole. The two vertically supporting portions 32 are located at both ends of the horizontally supporting portion 31. An adjusting hole 311 is penetrated through the middle of the horizontally supporting portion 31, and the horizontally supporting portion 31 is sleeved on the adjusting rod A14 through the adjusting hole 311, and the horizontally supporting portion 31 slides on the plate rack 1; The adjusting rod A14 is threadedly connected with the adjusting hole 311. When the adjusting rod A14 rotates in the fixed block A13, the adjusting rod A14 rotates in the adjusting hole 311 in a threaded connection manner. In this way, the horizontally supporting portion 31 moves on the top of the plate rack 1, thereby adjusting the distance between the support 3 and the winding roller A2.

[0029] Refer to Figure 1-6 It should be noted that there is an unclear expression "传动连接" in the original text. It is recommended to check and clarify the accurate technical term for a more precise translation.A sheet metal processing auxiliary device includes a row of pulleys 33 at both ends of a transverse support 31 near the bottom, located in an inner groove 11. When the transverse support 31 moves on the plate frame 1, the pulleys 33 roll in the inner groove 11, increasing the stability and smoothness of the movement of the support 3 on the plate frame 1. A linkage rod 34 rotatably passes through the transverse support 31, rotating within the transverse support 31. Both ends of the linkage rod 34 are equipped with stabilizing gears 341 located at both ends of the transverse support 31. The two stabilizing gears 341 mesh with the tops of two toothed blocks 12. When the transverse support 31 moves on the plate frame 1, the stabilizing gears 341 roll along the tops of the toothed blocks 12, further improving the stability and smoothness of the movement of the support 3 on the plate frame 1.

[0030] Reference Figure 1-6 An auxiliary device for sheet metal processing includes two vertical support portions 32, each with a sliding opening 322 and two sliding protrusions 321 in opposite positions. A sliding adjustment member 6 includes a sliding block 61 slidably located within the sliding opening 322, with two sliding sleeve openings 611 in opposite positions on the sliding block 61. The sliding block 61 is fitted onto the vertical support portion 32 through the sliding sleeve openings 611, allowing it to move along the sliding opening 322 on the vertical support portion 32. The adjustment is achieved by screws... The bolted connection locking method can position the sliding block 61 and the vertical support 32, allowing the sliding block 61 to be adjusted to the required height position on the vertical support 32. This further allows the rollers B4 and C5 to be adjusted to a suitable height position for use, i.e., the distance between rollers B4 and C5 can be adjusted. It should also be noted that both ends of rollers B4 and C5 are rotatably connected to the sliding block 61, so that rollers B4 or C5 can not only be adjusted in height but also without hindering rotation.

[0031] Reference Figure 1-6 An auxiliary device for sheet metal processing includes a sliding adjustment component 6, which further includes a fixed block B62 connected to a sliding block 61. An adjustment rod B64 is threaded through the fixed block B62, and a connecting block 63 is rotatably connected to the adjustment rod B64.

When adjusting the position of the sliding block 61 on the vertical support 32, the adjustment rod B64 is rotated in the connecting block 63 by using a wrench or other tools. The rotation of the adjustment rod B64 drives the fixed block B62 to connect via the threaded drive. Since the fixed block B62 is connected to the sliding block 61, when the fixed block B62 moves, the sliding block 61 actually moves in the sliding opening 322. After adjusting the position of the sliding block 61 on the vertical support 32, the sliding block 61 and the vertical support 32 are locked and fixed by bolts to maintain the desired stable position for use.
