Description

Technical Field

[0001] This utility model relates to the field of iron accessory processing technology, and in particular to a bending device for iron accessories. Background Technology

[0002] Iron fitting bending is a common metalworking process, mainly used to bend and shape iron fittings to meet the structural requirements of different projects or products. This process is widely used in construction, machinery manufacturing, power facilities, and the automotive industry, allowing iron fittings to adapt to complex installation environments or specific functional requirements. Iron fitting bending is typically done mechanically or manually. Mechanical bending utilizes equipment such as bending machines and stamping presses, applying pressure to the iron parts through dies to bend them according to preset angles and shapes, offering high precision and efficiency. Manual bending relies on the operator's experience, using tools such as hammers and jigs, and is suitable for small batches or special-shaped bending needs.

[0003] A search revealed that patent CN222790283U discloses a bending device for iron accessories. This device, with its support shaft, rotating shaft, handle, and bending shaft, can bend iron accessories. Through the arrangement of a slide, slider, and lead screw, rotating the lead screw adjusts the distance between the two support shafts, allowing for the processing of elliptical rings with varying bending distances, facilitating adjustment and improving practicality. However, the distance between the support shaft and the bending shaft is fixed, limiting the insertion of only iron accessories of a single size, resulting in low versatility. Furthermore, the lack of a locking mechanism after adjusting the distance between the two support shafts with the lead screw can lead to loosening over time, causing changes in the distance between the two support shafts and affecting processing accuracy. Therefore, further improvements are needed. Utility Model Content

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5As shown, a bending device for iron accessories is disclosed, comprising a workbench 1, which has a hollow interior and a strip-shaped opening 101 on its top wall. A bidirectional lead screw 2 is rotatably connected to the workbench 1 below the strip-shaped opening 101 via bearings. Two symmetrical first slides 3 are rotatably connected to the surface of the bidirectional lead screw 2 via threads. A slider 4 is fixed to the upper surface of each of the two first slides 3. A support plate 5 is fixed to each of the two sliders 4 through the strip-shaped opening 101. A central column 6 is fixed to the middle of the upper surface of the support plate 5. A turntable 7 is rotatably connected to the bottom surface of the central column 6 via bearings. A groove 71 is provided on the side of the upper surface of the turntable 7. A second slide 8 is slidably connected inside the groove 71. A side shaft 9 is rotatably connected to the upper surface of the second slide 8. One end of the bidirectional lead screw 2 is located outside the workbench 1 and is fixed with a handwheel 16. A first fastening bolt 17 is threaded through the side of the handwheel 16.

[0025] The workbench 1 has a first guide rod 15 fixed horizontally inside. The first guide rod 15 passes through the two first slide blocks 3 and is slidably connected to the first slide blocks 3.

[0026] In this embodiment, after the handwheel 16 rotates the bidirectional lead screw 2, the bidirectional lead screw 2 drives the two first slide blocks 3 and the slider 4 to move closer or further apart along the direction of the strip opening 101, thereby moving the support plate 5 and the central column 6, thus adjusting the distance between the two central columns 6. The first guide rod 15 increases the stability of the movement of the first slide blocks 3. After adjustment, the first fastening bolt 17 is tightened, and the first fastening bolt 17 is used to press against the outer wall of the worktable 1 to lock and fix the handwheel 16.

[0027] The upper surface of the worktable 1, located on one side of the strip opening 101, has a scale line. The scale line can be used to determine the specific distance between the two central columns 6 after adjustment.

[0028] Inside the slide groove 71, a one-way lead screw 12 is rotatably connected via a bearing. The one-way lead screw 12 passes through the second slide block 8 and is rotatably connected to the second slide block 8 via a thread.

[0029] In this embodiment, by rotating the one-way lead screw 12 in the forward or reverse direction, the one-way lead screw 12 can drive the second slide block 8 to slide along the slide groove 71, thereby driving the side shaft 9 to move and changing the distance between the side shaft 9 and the central column 6, so that iron accessories of different diameters can be inserted between the side shaft 9 and the central column 6.

[0030] A second guide rod 14 is fixed inside the slide groove 71. The second guide rod 14 passes through the second slide block 8 and is slidably connected to the second slide block 8.

[0031] By setting a second guide rod 14 through the second slide block 8, the stability of the second slide block 8 when moving along the slide groove 71 can be increased.

[0032] One end of the one-way lead screw 12 is located outside the turntable 7 and is fixedly connected to the arm 13, and the other end of the arm 13 is fixed with a handle.

[0033] The one-way lead screw 12 can be rotated via the arm 13, thereby adjusting the position of the second slide 8 and the side shaft 9. Furthermore, by horizontally rotating the arm 13, the turntable 7 can be driven to rotate around the central column 6.

[0034] The second slide block 8 has a side plate 10 fixed to its top, and the side plate 10 is located on the upper surface of the turntable 7. The middle of the side plate 10 is connected to a second fastening bolt 11 by a threaded rotation.

[0035] After adjusting the positions of the second slide block 8 and the side shaft 9, tighten the second fastening bolt 11. Use the second fastening bolt 11 to press against the surface of the turntable 7 to lock and fix the side plate 10 and the second slide block 8.

[0036] Working principle: First, according to the required size of the iron accessory to be processed, rotate the arm 13 on the side of each of the two turntables 7 to adjust the distance between the side shaft 9 and the center column 6 on the surface of each turntable 7, so that the distance is just enough to fit the iron accessory of the required size. After adjustment, tighten the second fastening bolt 11 to lock the second side shaft 9. Next, rotate the handwheel 16 to adjust the distance between the two center columns 6. After adjustment with reference to the scale line, tighten the first fastening bolt 17 to lock and fix the double-acting screw 2. When starting to bend the iron accessory, rotate the two arm 13 to a parallel state (e.g., ...). Figure 5 Next, insert the iron accessory material between the side shafts 9 and the central column 6 on the surface of the two turntables 7. Then rotate the two arms 13 away from each other so that the two turntables 7 rotate around the two central columns 6 respectively. Use the two side shafts 9 to bend the two ends of the iron accessory.
