Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a galvanized pipe bending machine with a guiding structure. Background Technology

[0002] Galvanized pipe is a type of steel pipe with a zinc layer coated on its surface through hot-dip galvanizing and electro-galvanizing processes. Hot-dip galvanizing involves immersing the steel pipe in molten zinc, resulting in a uniform, thick zinc layer that bonds tightly to the steel pipe substrate. This provides excellent corrosion resistance, effectively resisting the erosion of the atmosphere, water, and various chemicals. Galvanized pipe plays a vital role in numerous industries and has become an indispensable basic material in modern industry and daily life.

[0003] A galvanized pipe bending machine with a guiding structure is a specialized device for bending galvanized pipes. Its core advantage lies in its unique guiding structure, which precisely guides the galvanized pipe during the bending process, ensuring its stability under bending stress and preventing deviation or twisting. Operators can more accurately control the bending angle and curvature, improving bending precision and ensuring that the processed galvanized pipes meet the size and shape requirements of different applications. This significantly improves production efficiency and product quality, playing a vital role in industries such as construction and pipeline installation that require large quantities of bent galvanized pipes. This provides strong support for the smooth implementation of various engineering projects. During use, galvanized pipes of different materials and wall thicknesses have different hardness, toughness and mechanical properties. The guide structure cannot automatically adjust according to the specific characteristics of the pipe. During bending, the pipe surface is prone to scratches, wrinkles or even cracks, especially for thinner and harder pipes. In the existing technology, guide components can be quickly replaced and adjusted. Different specifications and shapes of guide wheels and guide grooves are equipped for pipes of different materials and wall thicknesses. However, when processing galvanized pipes, due to the different sizes, the specific dimensions need to be adjusted in advance, which reduces the amount of material to be cut. Utility Model Content

A bevel gear 2 9 is fixedly connected, and bevel gear 1 5 meshes with bevel gear 2 9. A heat dissipation mechanism 2 is installed on the top left side of the machine body 1. The heat dissipation mechanism 2 is used to cool the bending part of the material. A support plate 10 is connected to the bottom of the machine body 1. A support frame 11 is fixedly connected to the bottom of the support plate 10 to support the whole. A warning sign 12 is set on the front right side of the outer wall of the support frame 11. A screw 13 is threadedly connected to the outer side of the warning sign 12. The warning sign 12 is fixed by the screw 13 to serve as a warning.

[0032] Specifically, a knob 4 is located on the rear side of the top of the body 1 and the rear side of the protective box 3. The front end of the knob 4 is fixedly connected to the first bevel gear 5. Multiple limiting blocks 6 are located on both sides of the interior of the protective box 3. These limiting blocks 6 limit the range of movement. The outer side of the limiting blocks 6 is rotatably connected to a threaded rod 7. The outer side of the threaded rod 7 is connected to a clamping block 8 via threads. The other end of the threaded rod 7 is fixedly connected to a second bevel gear 9. The first bevel gear 5 and the second bevel gear 9 mesh with each other. When the knob 4 is rotated, it drives the first bevel gear 5 to rotate, thereby causing the second bevel gear 9 to move accordingly. The rotation of the bevel gear 9 causes the threaded rod 7 to rotate within the limited range of the limiting block 6. The rotation of the threaded rod 7 pushes the clamping block 8 to move along its axial direction, thereby achieving effective clamping of metals of different specifications. The bottom of the machine body 1 is provided with a structure connected to the bearing plate 10. The bottom of the bearing plate 10 is fixedly connected to the support frame 11 to support the overall structure. A warning sign 12 is provided on the front right side of the outer wall of the support frame 11.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The heat dissipation mechanism 2 includes a hollow box 201, which is located at the top front of the body 1. A motor 202 is installed at the bottom of the hollow box 201. A rotating shaft 203 is fixedly connected to the output end of the motor 202. The rotating shaft 203 is rotated by the kinetic energy of the motor 202. A sprocket 204 is fixedly connected to the outside of the rotating shaft 203. A rotating rod 205 is rotatably connected to the top of the hollow box 201. A sprocket 206 is fixedly connected to the outside of the rotating rod 205. The sprocket 204 is meshed with the sprocket 206 through a chain 207. Multiple fans 208 are equidistantly arranged on the outside of the chain 207 and can move. A fixing block 14 is fixedly connected to the front left side of the outer wall of the support frame 11. A hook 15 is fixedly connected to the outside of the fixing block 14 and can be used to hang some tools.

[0034] Specifically, when the motor 202 starts, its output end will drive the shaft 203 to rotate, which in turn will cause the sprocket 204 to rotate. Since the sprocket 204 and the sprocket 206 are meshed with each other through the chain 207, the rotation of the sprocket 204 will drive the chain 207 to move. At the same time, the sprocket 206 will also rotate inside the hollow box 201. The movement of the chain 207 will drive the fan 208 on its outside to rotate together, so that the fan 208 can move and effectively cool down the area where the metal is being bent. The outer left front end of the support frame 11 is provided with a fixing block 14, and a hook 15 is fixed on the outside of the fixing block 14 to facilitate the hanging of various tools.

[0035] Reference Figure 2 and Figure 3 A mounting block 16 is fixedly connected to the rear side of the support frame 11, and a handle 17 is fixedly connected to the outer side of the mounting block 16 for better operation. Corner guards 18 are provided at the four corners of the top of the support plate 10. Screws 19 are threadedly connected to the outer side of the corner guards 18.

A light bulb 21 is provided at the top of the output rod 20 for illumination.

[0036] Specifically, the rear side of the support frame 11 is fixedly connected to the mounting block 16. The outer side of the mounting block 16 is provided with a handle 17 for easy operation. The top four corners of the support plate 10 are provided with corner guards 18. The corner guards 18 are connected to screws 19 through the outer threads and are fixed with screws 19 to provide protection. The top rear left side of the support plate 10 is provided with an output rod 20. A bulb 21 is installed on the top of the output rod 20 to provide lighting.

[0037] Working principle: A knob 4 is located on the rear side of the protective box 3 at the top of the machine body 1. A bevel gear 5 is fixedly connected to the front of the knob 4. There are multiple limit blocks 6 on the left and right sides inside the protective box 3. The limit blocks 6 play a limiting role. A threaded rod 7 is rotatably connected to the outside of the limit block 6. A clamping block 8 is threadedly connected to the outside of the threaded rod 7. A bevel gear 9 is fixedly connected to the other end of the threaded rod 7. The bevel gear 5 and the bevel gear 9 mesh. When the knob 4 is turned, the bevel gear 5 is driven to rotate, which in turn causes the bevel gear 9 to rotate. The bevel gear 9 drives the threaded rod 7 to rotate under the limitation of the limit block 6. The rotation of the threaded rod 7 pushes the clamping block 8 to move along the axial direction of the threaded rod 7, so as to effectively clamp metal of different specifications.

[0038] When the motor 202 starts, its output end drives the shaft 203 to rotate, which in turn causes the first sprocket 204 to rotate. Since the first sprocket 204 meshes with the second sprocket 206 through the chain 207, the rotation of the first sprocket 204 will drive the chain 207 to rotate. At the same time, the second sprocket 206 will also rotate inside the hollow box 201. When the chain 207 rotates, it will drive the fan 208 on its outer side to move together, so that the fan 208 can move and effectively cool the part of the metal that is being bent.
