Description

Technical Field

[0001] The present application relates to the technical field of tower pipe bending processing, and in particular to an automatic tower pipe bending device. Background Art

[0002] Tower pipe fittings are an important part of tower construction. They are usually made of metal materials such as steel and have a variety of shapes and specifications. Common tower pipe fittings include angle steel, steel pipe, etc. These pipe fittings play a supporting, connecting and stabilizing role in the tower structure. Angle steel pipe fittings have good strength and rigidity and can be used to build the frame and support part of the tower. Steel pipe fittings have high compressive strength and good appearance quality and are often used in some parts that have high requirements for appearance or need to withstand greater pressure. Tower pipe fittings need to have good corrosion resistance and durability to adapt to various natural environmental conditions. During the construction of the tower, select appropriate tower pipe fittings according to the design requirements for combined installation to ensure that the structure of the tower is stable, safe and reliable, and can withstand the effects of various natural forces, such as wind gravity, etc., to provide stable infrastructure support for power transmission, communication, etc. At present, during the processing of iron tower pipe fittings, a bending device is usually required to assist in the bending process. However, during the use of existing equipment, the bending device mostly uses the existing steel pipe bending device, which is mostly unable to perform bending operations on steel pipes of different sizes, or can only perform bending operations on steel pipes of different sizes manually, which not only wastes labor costs, but also cannot bend steel pipes that are too large in size. Although there are some improved designs in the prior art, in the prior art, first remove the small bolts and nuts, remove the moving mechanism, take out the shaft housing and the rotating shaft, and replace the bending passive parts with the required models; then take out the large bolts, replace the bending active parts with the required models, and then reinstall the device components according to the steps, put the steel pipe into the fixing mechanism for fixing, and then place the replaced bending passive parts and bending active parts on both sides of the steel pipe through the moving mechanism, and finally use the rotating mechanism to bend the steel pipe, thereby realizing the bending processing of steel pipes of different sizes; It can be seen that the existing device mainly relies on replacing the bending guide wheel when adapting to the processing of pipes of different thicknesses. However, this method has many disadvantages in actual operation; First, the overall operation process is cumbersome and inconvenient. When replacing the guide wheel, a series of disassembly steps need to be performed first, such as removing small bolts and nuts, removing the moving mechanism, taking out the shaft housing and the rotating shaft, etc., and then installing the new guide wheel. Finally, the device components are reinstalled according to the steps. This process not only has many steps, but also requires the operator to have a certain level of technical skills and patience. If you are not careful, installation errors may occur, affecting the normal operation of the equipment; Secondly, this method of replacing the guide wheel greatly reduces the bending production efficiency during use. Each replacement of the guide wheel takes a lot of time. From disassembly to installation, the whole process may take several hours or even longer. This is undoubtedly a huge challenge for companies with tight production tasks and seriously affects the production progress. Thirdly, frequent disassembly and assembly also consumes a lot of manpower and material resources. Frequent disassembly and installation not only requires a large amount of manpower, but may also cause certain damage to other parts of the equipment, increasing the maintenance cost of the equipment. In addition, frequent disassembly and assembly may also lead to a decrease in the accuracy of the equipment and affect the quality of the bending process. It can be seen that the existing device is extremely cumbersome and inconvenient to use in the overall use of replacing the bending guide wheel to adapt to the processing of pipes of different thicknesses, which seriously affects the production and processing efficiency of the existing technical equipment. Therefore, it is urgent to improve the existing technology to improve the ease of use and production efficiency of the equipment. Summary of the invention

[0025] The use principle and advantages are as follows: the device exhibits excellent performance during use by setting a lateral displacement mechanism 300 and a longitudinal displacement mechanism 200. First, the second motor 220 is started to run, and the second motor 220 can drive the first screw rod 240 to rotate. As the first screw rod 240 rotates, it can assist in driving the slide 230 to slide smoothly on the inner side of the slide groove 210. The slide 230 slides in the slide groove 210, which can assist in adjusting the longitudinal displacement of the first motor 400. The longitudinal displacement of the first motor 400 can accurately adjust the position of the adjustable bending guide wheel 600 located in the middle. At the same time, the electric push rod 310 is started to run, and the electric push rod 310 can push the slider 330 inside the side groove 320 to slide. Through the sliding of the slider 330, the adjustable bending guide wheel 600 on the top of the slider 330 can be assisted to achieve lateral displacement. During use, the mutual distances of the three adjustable bending guide wheels 600 can be flexibly adjusted. Overall, by flexibly adjusting the positions of the three adjustable bending guide wheels 600, the bending state can be flexibly adjusted according to the requirements of the tower pipe racks with different spans, which greatly improves the bending adaptability of the device during the overall application period. By setting the adjustable bending guide wheel 600, the device exhibits many advantages during use. The limiting guide ring 653 on the outer carriage 652 of the slide 651 can closely fit the bent pipe to be processed. The overall cross-sectional shape of the limiting guide ring 653 is triangular, and the inclined surface of the limiting guide ring 653 can fit the pipe, playing an auxiliary guiding role. The two limiting guide rings 653 are mutually fitted and limited, which can assist in the contact and guidance of the iron tower pipe. At this time, the first motor 400 is started to run, and the first motor 400 can drive the outer wheel disc 610 to rotate, thereby driving the rail frame 620 and the limiting guide ring 653 outside it to rotate, thereby assisting in the transmission and guidance of the iron tower pipe. The three groups of limiting guide rings 653 mutually contact and squeeze the limiting guide, which can assist in realizing the bending function. During the bending process, the inner inclined surfaces of the limiting guide rings 653 are close to each other, so it can adapt to pipes of different thicknesses through the inclined surface guidance. If the diameter of the pipe rack is not up to standard, it can be adjusted with the assistance of the adjustment component 640 and the limit component 650, so as to further improve the adaptability of the device during bending. This direct adjustment design does not require the replacement of the guide wheel, and the overall use efficiency is more efficient. By setting the adjustment component 640, the transmission component 630 and the limit component 650 of the adjustable bending guide wheel 600, the device is more convenient and efficient during use. The handrail 649 can be operated by hand, and then the thumb can be squeezed on the handrail arm 648 to drive the limit arm 646 inside the cross rail 644 to move outward. When the limit arm 646 moves outward, the limit spring 645 will be pulled out. The limit arm 646 can also drive the limit pin 647 to disengage from the limit hole 642. At this time, the limit arm 646 can be moved outward. The operating armrest 649 is twisted to drive the connecting rod 632 to rotate. The connecting rod 632 can drive the second screw rod 631 to rotate. Since the threads at both ends of the second screw rod 631 rotate in opposite directions, the two slides 651 can be synchronously driven to slide back and forth inside the rail frame 620. If a pipe with a larger diameter needs to be processed, the two slides 651 can be adjusted to drive the slide 652 to move outward. At this time, the spacing between the limiting guide rings 653 on the slide 652 becomes larger, and its inclined surface can adapt to thicker pipes. If a thinner pipe needs to be set, the two slides 651 can be adjusted to move inward. At this time, the slide 652 drives the limiting guide rings 653 to move inward, and the spacing between the limiting guide rings 653 becomes smaller, and its inclined surface can stably clamp the thinner pipe. After the adjustment is completed, just loosen the operating handrail 649, and the limit spring 645 resets to drive the limit arm 646 to slide toward the inner side of the cross rail 644, and then drive the limit pin 647 to insert into the inner side of the limit hole 642, and then the cross rail 644 can be locked and fixed, and then the connecting rod 632 and the screw rod at the bottom thereof can be fixed, so that the limit guide ring 653 can be in a relatively stable state. It can be seen that the adjustable spacing design of the limit guide tube of the device enables the device to adapt to iron tower pipes of different thicknesses to the greatest extent during use, further improving the overall production and processing adaptability of the device.
