Description

Technical Field

[0001] This utility model relates to the field of metal parts processing equipment technology, and in particular to an iron accessory bending and forming device. Background Technology

[0002] Iron fittings refer to auxiliary components used to connect, fix, or support iron structures and equipment. They typically include bolts, nuts, washers, clamps, hinges, etc., and are widely used in construction, machinery, power, transportation, and other fields. They are characterized by high strength, corrosion resistance, and easy installation, effectively enhancing the stability and durability of structures, and are indispensable basic accessories in various engineering projects.

[0003] Bending is a common processing method in the manufacturing of various attachments. Bending iron attachments involves applying pressure to metal sheets or profiles using mechanical equipment, causing plastic deformation at specific locations to form the desired angle or curvature. Common bending methods include stamping bending, roll bending, and CNC bending, suitable for manufacturing various iron fittings such as brackets, boxes, and connectors. In the processing of rod-shaped workpieces, the workpiece is placed on one side of a circular locating post, and a tool is used to bend it. The workpiece deforms due to the obstruction of the locating post, forming a ring or other shape.

[0004] Currently, bending equipment used for rod-shaped workpieces often has a fixed bending radius, which means that most of the same equipment can only process ring-shaped workpieces with a fixed diameter. This makes it difficult to adapt to complex processing requirements. Adjusting the processing diameter requires disassembling the equipment components, which is time-consuming and labor-intensive. It also requires manufacturers to have corresponding replacement parts, increasing warehousing pressure. Utility Model Content

[0008] Preferably, a first toothed ring is provided on the side of the lower limiting plate near the installation chamber, and a first gear is provided on the outer side of the first toothed ring. The first gear meshes with the first toothed ring and is rotatably connected to the bending table.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5 This utility model provides an embodiment of a bending and forming device for iron accessories, comprising a base 1, a lower limiting plate 4, and an adjusting assembly. A bending table 101 is disposed above the base 1, and an upper limiting plate 3 and a lower limiting plate 4 are disposed above the bending table 101. The upper limiting plate 3 is fixedly connected to the bending table 101, and the lower limiting plate 4 is rotatably connected to the bending table 101. The upper limiting plate 3 has a straight groove 301, and the lower limiting plate 4 has an arc-shaped groove 401. The widths of the straight groove 301 and the arc-shaped groove 401 are the same. The upper limiting plate 3 and the lower limiting plate 4... The inner sliding connection is provided with a support column 5 for bending, and a bending roller 2 for bending is provided on one side of the bending table 101. An adjustment component is provided at the bottom of the bending roller 2. By driving the lower limiting plate 4 to rotate, the position of all support columns 5 is adjusted synchronously by the movement changes of the arc groove 401 and the straight groove 301, so that the circumference diameter formed by the support columns 5 changes, thereby adjusting the bending diameter. At the same time, the position of the bending roller 2 is adjusted by the adjustment component, so that the bending roller 2 can still be in close contact with the workpiece after the bending radius is adjusted.

[0023] Please see Figure 2 and Figure 4In this embodiment, a rotating chamber 103 is provided on the inner side of the bending table 101. A lower limiting plate 4 is rotatably installed in the rotating chamber 103. An installation chamber 104 is provided on one side of the rotating chamber 103. A first toothed ring 402 is provided on the side of the lower limiting plate 4 near the installation chamber 104. A first gear 501 is provided on the outer side of the first toothed ring 402. The first gear 501 meshes with the first toothed ring 402 and is rotatably connected to the bending table 101. A worm gear 502 is provided at the bottom of the first gear 501. The worm gear 502 and the first gear 501 are fixedly connected by a keyway. A worm gear 503 is provided on one side of the wheel 502, and the worm gear 503 meshes with each other. A third motor 803 is provided on the outer side of the bending table 101, and the output end of the third motor 803 is fixedly connected to the worm gear 503. The rotating chamber 103 is used to accommodate the lower limiting plate 4, and the mounting chamber 104 is used to accommodate the first gear 501, the worm gear 502 and the worm 503. When adjusting the bending diameter, the third motor 803 drives the worm gear 503 to rotate and drives the worm gear 503 to rotate, thereby driving the first gear 501 to rotate and using the first gear ring 402 to make the lower limiting plate 4 rotate.

[0024] Please see Figure 5 In this embodiment, a rotating groove 102 is provided at the connection between the base 1 and the bending table 101. A second gear ring 6 is rotatably connected to the outside of the rotating groove 102. A first motor 801 is provided above the base 1. A second gear 9 is provided at the output end of the first motor 801. The second gear 9 meshes with the second gear ring 6. The adjustment assembly includes a threaded screw 7, a connecting rod 702, and a second motor 802. A mounting plate 601 is provided on one side of the second gear ring 6. A threaded screw 7 is rotatably connected to the inside of the mounting plate 601. The two ends of the threaded screw 7 have opposite thread directions. A movable seat 701 is threadedly connected to the outside of the threaded screw 7. A connecting seat 703 is provided at the bottom of the bending roller 2. A connecting rod 702 is provided between the connecting seat 703 and the movable seat 701. The two ends of the connecting rod 702 are rotatably connected to the connecting seat 703 and the movable seat 701, respectively. The first motor 801 drives the second gear 9 to rotate, thereby driving the second gear ring 6 to rotate, so that the bending roller 2 rotates to bend the workpiece. After adjusting the bending diameter, the second motor 802 drives the threaded screw 7 to rotate, so that the two sets of movable seats 701 move closer or further away from each other. Thus, the connecting rod 702 drives the connecting seat 703 to move, so that the bending roller 2 moves closer or further away from the bending table 101, so that the bending roller 2 can adapt to different bending diameters.

[0025] During processing, the first motor 801 drives the second gear 9 to rotate, thereby driving the second gear ring 6 to rotate, causing the bending roller 2 to move to one side limit position. Then, the workpiece is inserted into the gap between the support column 5 and the bending roller 2, and the other end of the workpiece is fixed. Then, the first motor 801 drives the second gear 9 to rotate again to bend the workpiece.

[0026] When adjusting the bending radius, the third motor 803 drives the worm gear 503 to rotate, thereby driving the first gear 501 to rotate and using the first gear ring 402 to make the lower limiting plate 4 rotate. By utilizing the movement changes of the arc groove 401 and the straight groove 301, the position of all support columns 5 is adjusted synchronously, so that the circumference diameter formed by the support columns 5 changes, thereby making the bending diameter infinitely adjustable. Then, the second motor 802 drives the threaded screw 7 to rotate, so that the two sets of movable seats 701 move closer or further away from each other. This allows the connecting rod 702 to drive the connecting seat 703 to move, so that the bending roller 2 moves closer or further away from the bending table 101, allowing the bending roller 2 to adapt to different bending diameters.

[0027] Through the above steps, by driving the lower limiting plate 4 to rotate, the position of all support columns 5 is synchronously adjusted by the movement changes of the arc groove 401 and the straight groove 301, so that the circumferential diameter formed by the support columns 5 changes, thereby adjusting the bending diameter. At the same time, the position of the bending roller 2 is adjusted by the adjustment component, so that the bending roller 2 can still be in close contact with the workpiece after the bending radius is adjusted.
