Description

Technical Field

[0001] This utility model relates to the field of common plate flange processing technology, and in particular to a folding and grinding device for common plate flange processing. Background Technology

[0002] A flange bending and grinding device is a specialized machine for bending and grinding flanges. This device combines the functions of bending and grinding. The bending section typically includes a bending mechanism that uses mechanical or hydraulic force to bend the flange edge to the desired angle. This step is crucial in flange processing because it ensures the strength and sealing of the flange edge. The bending mechanism is usually designed with flanges of different sizes and thicknesses in mind for flexible adjustments.

[0003] The existing common plate flanges have finished processing plates scattered on the ground, which requires staff to sort and store them, increasing the labor intensity of the staff and reducing work efficiency;

[0004] An existing patent (publication number: CN212703856U) discloses a sorting device for a common plate flange bending machine, which includes an auxiliary fixing device, a feeding conveyor belt, and a conveyor width adjustment component. The auxiliary fixing device includes an auxiliary fixing device one and an auxiliary fixing device two, which are respectively disposed on both sides of the pressure roller of the bending machine. By setting up the auxiliary fixing device, the plate material can be fixed during the operation of the common plate flange bending machine without manual support, reducing the labor intensity of the operator. By setting up the conveyor belt width adjustment component, plates of different widths at the upper end of the feeding conveyor belt are limited, so that the plates are kept in a consistent position when entering the storage box, achieving the effect of automatic sorting.

[0005] To address the aforementioned issues, existing patents propose solutions that use a conveyor belt width adjustment component to limit the movement of plates of different widths at the top of the unloading conveyor belt, ensuring that the plates maintain a consistent position when entering the storage box, thus achieving an automatic sorting effect. However, this solution has limitations when processing common plate flange workpieces. Because common plate flange workpieces may generate burrs, unevenness, or form an oxide layer during the bending process, they often need to be polished again after bending. This not only makes the workflow more cumbersome but also reduces the overall work efficiency. Summary of the Invention

[0006] The purpose of this utility model is to provide a bending and grinding device for processing common plate flanges, which can bend the protruding part of the workpiece in the vertical direction, and the stepper motor drives the gear to mesh with the rack to rotate, so that the stepper motor can move in the horizontal direction. The grinding plate grinds the burrs and other impurities at the bending point of the workpiece, thereby eliminating the need for subsequent grinding operations, improving processing efficiency, and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a bending and grinding device for processing a common plate flange, comprising a device base, two conveying rollers installed at the lower end of the device base, a bending mechanism for bending the workpiece provided on the right side of the device base, a driving mechanism for driving the bending mechanism at one end of the device base, and a length-fixing mechanism for fixing the length of the workpiece provided on the side wall of the bending mechanism.

[0008] The bending mechanism includes a bending member, which is located on the right side of the device base. A movable part is installed inside the bending member. A grinding plate is fixed to the inner wall of the movable part. Guide blocks that slide and connect with the inner wall of the bending member are fixed at both ends of the movable part. A stepper motor is fixed to the side wall of the movable part by screws. A gear is fixed to the power output shaft of the stepper motor. A rack fixed to the inner wall of the bending member is meshed with the outer wall of the gear.

[0009] Preferably, a protective rubber pad is fixed to the side wall at the upper end of the folded edge piece.

[0010] Preferably, the driving mechanism includes a fixed rod that passes through the inner wall of the device base and is fixedly connected to the folded edge piece, and a worm gear is fixed to one end of the fixed rod.

[0011] Preferably, the sidewall of the worm gear is engaged with a worm, and the input shaft of the worm is fixed with a drive motor that is bolted to the base of the device.

[0012] Preferably, the fixed-length mechanism includes two connectors, both of which are fixed to the side wall of the folded edge piece, and both connectors are slidably connected to a limit rod inside.

[0013] Preferably, the outer walls of both connectors are fitted with limiting bolts that abut against the outer surface of the limiting rod.

[0014] Preferably, a pressure roller is installed horizontally inside the device base, and both ends of the pressure roller are rotatably connected to mounting blocks via bearings. The mounting blocks are slidably connected to the inner wall of the device base, and an adjusting screw is threaded into the inside of the mounting blocks.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The bending mechanism can bend the protruding part of the workpiece in the vertical direction, and the stepper motor drives the gear to mesh with the rack to rotate, so that the stepper motor can move in the horizontal direction. The grinding plate grinds the burrs and other impurities at the bending point of the workpiece, so that no subsequent grinding operation is needed, thus improving processing efficiency.

[0017] 2. The fixed-length mechanism can limit the bending length of the workpiece. By loosening the limiting bolts on the connecting parts, the fixing of the limiting rod can be released, thus allowing the horizontal length of the limiting rod to be adjusted, which facilitates quantitative bending of different lengths.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A bending and grinding device for processing a common plate flange includes a device base 1. Two conveying rollers 2 are installed at the lower end of the device base 1. A bending mechanism for bending the workpiece is provided on the right side of the device base 1. A driving mechanism for driving the bending mechanism is provided at one end of the device base 1. A length-fixing mechanism for fixing the workpiece to a fixed length is provided on the side wall of the bending mechanism.

[0028] The bending mechanism includes a bending element 3, which is located on the right side of the device base 1. A movable element 31 is installed inside the bending element 3. A grinding plate 32 is fixed to the inner wall of the movable element 31. Guide blocks 33 that slide and connect with the inner wall of the bending element 3 are fixed to both ends of the movable element 31. A stepper motor 34 is fixed to the side wall of the movable element 31 by screws. A gear 35 is fixed to the power output shaft of the stepper motor 34. A rack 36 fixed to the inner wall of the bending element 3 is meshed with the outer wall of the gear 35. A protective rubber pad 4 is fixed to the upper side wall of the bending element 3. The driving mechanism includes a fixed rod 5, which passes through the inner wall of the device base 1 and is fixedly connected to the bending element 3. A worm gear 51 is fixed to one end of the fixed rod 5. A worm 52 is meshed with the side wall of the worm gear 51. A drive motor 53 that is bolted to the device base 1 is fixed to the input shaft of the worm 52.

[0029] By adopting the above technical solution, before using the folding and grinding device for processing the common plate flange, the device base 1 is first placed in a suitable position. The drive motor 53 drives the worm gear 52 to mesh with the worm wheel 51 to rotate, which in turn drives the fixed rod 5 to rotate, so that the folding part 3 moves and bends the protruding part of the workpiece in the vertical direction. The protective rubber pad 4 set on the folding part 3 plays a certain buffering role, thereby avoiding the folding part 3 from directly contacting the outer wall of the workpiece and causing damage. At the same time as the workpiece is bent, the stepper motor 34 drives the gear 35 to mesh with the rack 36 to rotate. Since the rack 36 and the folding part 3 are fixed, the stepper motor 34 can move in the horizontal direction, driving the moving part 31 to move, so that the grinding plate 32 grinds the burrs and other impurities at the bending point of the workpiece. The guide block 33 set can guide the moving part 31.

[0030] Specifically, such as Figure 1 and Figure 2As shown, the fixed length mechanism includes two connectors 6, both of which are fixed to the side wall of the folded edge 3. Both connectors 6 are slidably connected to limit rods 62 inside. Both connectors 6 are equipped with limit bolts 61 that abut against the outer surface of the limit rods 62 on their outer walls. A pressure roller 7 is installed horizontally inside the device base 1. Both ends of the pressure roller 7 are rotatably connected to mounting blocks 8 via bearings. The mounting blocks 8 are slidably connected to the inner wall of the device base 1. An adjusting screw 9 is threadedly connected inside the mounting blocks 8.

[0031] By adopting the above technical solution, the workpiece to be bent is placed on two conveyor rollers 2. The two conveyor rollers 2 are driven by an external motor to convey the workpiece, so that the workpiece is conveyed between one conveyor roller 2 and the pressure roller 7. By turning the set adjustment screw 9, the mounting block 8 can be driven to move vertically, thereby adjusting the distance between the pressure roller 7 and the conveyor roller 2, which is convenient for limiting the workpiece of different thicknesses. When not bent, the folding part 3 is in the horizontal direction, and the limiting rod 62 on the folding part 3 is L-shaped. When the workpiece is conveyed and contacts the inner wall of the limiting rod 62, the conveying stops, thereby limiting the bending length of the workpiece. By loosening the limiting bolt 61 on the connecting part 6, the fixing of the limiting rod 62 is released, so the horizontal length of the limiting rod 62 can be adjusted, which is convenient for quantitative bending of different lengths.

[0032] Working principle: The workpiece is conveyed between a conveying roller 2 and a pressing roller 7. Tightening the adjusting screw 9 can drive the mounting block 8 to move vertically, adjusting the distance between the pressing roller 7 and the conveying roller 2. The conveying stops after the workpiece is conveyed and contacts the inner wall of the limiting rod 62. By loosening the limiting bolt 61 on the connecting piece 6, the fixing of the limiting rod 62 is released, which allows the horizontal length of the limiting rod 62 to be adjusted, facilitating quantitative bending of different lengths. The drive motor 53 drives the worm gear 52 to mesh with the worm wheel 51 to rotate, which in turn drives the fixed rod 5 to rotate, causing the bending piece 3 to move and bend the protruding part of the workpiece in the vertical direction, thus avoiding direct contact between the bending piece 3 and the outer wall of the workpiece and causing damage. At the same time as the workpiece is bending, the stepper motor 34 drives the gear 35 to mesh with the rack 36 to rotate. Since the rack 36 and the bending piece 3 are fixed, the stepper motor 34 can move in the horizontal direction, driving the moving part 31 to move, so that the grinding plate 32 grinds the burrs and other impurities at the bending point of the workpiece.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
