Description

Technical Field

[0001] This utility model relates to the field of U-bolt technology, specifically to a U-bolt cold bending forming device. Background Technology

[0002] U-bolts, also known as U-bolts, are non-standard parts named for their U-shaped shape. They have threads at both ends for attaching with nuts and are primarily used to secure tubular objects such as water pipes or sheet-like objects such as leaf springs in automobiles. Because the way they secure objects resembles a person riding a horse, they are also called "riding bolts." In recent years, due to the rapid development of industries such as power technology, the demand for structural steel materials has increased significantly, leading to a growing demand for U-bolts. The variety and specifications of U-bolts required are also increasing, thus necessitating a cold-bending forming device for U-bolts.

[0003] When operators are producing U-bolts, they often use corresponding U-bolt forming devices. Although the existing devices can achieve the forming purpose, they lack auxiliary positioning mechanisms in actual use, which may cause deviations during processing, thus affecting the forming quality. In addition, the degree of automation is low, and manual assistance is often required, which reduces their practicality. Utility Model Content

[0004] The purpose of this utility model is to provide a U-bolt cold bending forming device to solve the problem mentioned in the background art. When operators are producing U-bolts, they often use corresponding U-bolt forming devices. Although the existing devices can achieve the forming purpose, they lack auxiliary positioning mechanisms in actual use. They may deviate during processing, which will affect the forming quality. In addition, the degree of automation is low, and manual assistance is often required, which reduces the practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a U-shaped bolt cold bending forming device, comprising a base plate, a U-shaped block fixedly installed on the top of the base plate, a square tube fixedly installed on the top of the base plate on the right side of the U-shaped block, a threaded rod rotatably installed inside the square tube, a threaded sleeve threaded onto the surface of the threaded rod, a sliding groove provided at both ends of the square tube, a slider movably installed inside the sliding groove, one end of the slider being fixedly connected to one end of the threaded sleeve, a movable plate fixedly installed at the other end of the slider, a rotary motor fixedly installed on one side of the square tube, and the output end of the rotary motor passing through the square tube and fixedly connected to one side of the threaded rod.

[0006] Preferably, a push plate is fixedly installed on one side of the movable plate, a strip groove is opened on one side of the push plate, a round rod is fixedly installed inside the strip groove, a movable block is movably sleeved on the surface of the round rod, a spring is fixedly installed between the movable block and the strip groove, the inner surface of the spring is movably connected to the outer surface of the round rod, and a movable rod is fixedly installed on one side of the movable block.

[0007] Preferably, the bottom plate has a storage groove inside, and a lead screw is rotatably installed inside the storage groove, with a sleeve threaded onto the surface of the lead screw.

[0008] Preferably, an adjustment motor is fixedly installed on one side of the base plate, and the output end of the adjustment motor passes through the base plate and is fixedly connected to one side of the lead screw.

[0009] Preferably, the top two ends of the base plate are provided with long grooves, and a connecting rod is movably installed inside the long grooves, with the bottom of the connecting rod being fixedly connected to the top of the sleeve rod.

[0010] Preferably, a push rod is fixedly installed on the top of each connecting rod, and a mounting groove is opened on one side of each push rod, and a forming wheel is rotatably installed inside the mounting groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This U-bolt cold bending forming device, during daily use, involves the operator placing the steel on top of the base plate and one side of the U-shaped block, then starting the rotary motor. The rotary motor causes the threaded rod to rotate, which in turn causes the threaded sleeve to slide inside the square tube. At this time, the threaded sleeve causes the slider to slide inside the groove, which in turn causes the moving plate to slide. The moving plate then causes the push plate to slide until the steel is placed between the push plate and the U-shaped block. Simultaneously, the outer surface of the steel continuously presses against the outer surface of the moving rod, which in turn causes the moving block to slide inside the strip groove and on the surface of the round rod. The moving block then compresses the spring. This device, through the U-shaped block, push plate, and moving rod, limits the movement of the steel, reducing accidental slippage during the forming process and thus improving the forming quality.

[0013] In daily use, this U-bolt cold bending forming device involves the operator starting and adjusting the motor. The motor's operation causes the lead screw to rotate, which in turn drives the sleeve rod to slide inside the placement groove. This sleeve rod then drives the connecting rod to slide inside the long groove, which in turn drives the push rod to slide. Simultaneously, the push rod drives the forming wheel to slide. When the forming wheel reaches the outer surface of the steel, it compresses it. As the forming wheel continues to move, it causes the forming wheel to rotate inside the mounting groove. Subsequently, the forming wheel continuously compresses the steel on the outer surface of the U-shaped block, thus automatically forming it. Attached Figure Description

At this time, the threaded sleeve 5 drives the slider 7 to slide inside the slide groove 6. Subsequently, the slider 7 drives the moving plate 8 to slide. Then, the moving plate 8 drives the push plate 10 to slide until the steel is placed between the push plate 10 and the U-shaped block 2. At the same time, the outer surface of the steel will continuously press against the outer surface of the moving rod 14. Subsequently, the moving rod 14 will drive the moving block 13 to slide inside the strip groove 11 and on the surface of the round rod 12. Then, the moving block 13 will... Spring 24 compresses and squeezes the steel. Then, the operator starts the adjusting motor 18. The operation of the adjusting motor 18 causes the lead screw 16 to rotate. The lead screw 16 then drives the sleeve 17 to slide inside the storage groove 15. At this time, the sleeve 17 drives the connecting rod 20 to slide inside the long groove 19. The connecting rod 20 then drives the push rod 21 to slide. At the same time, the push rod 21 drives the forming wheel 23 to slide. When the forming wheel 23 is on the outer surface of the steel, it will squeeze it. As it moves, the steel will drive the forming wheel 23 to rotate inside the mounting groove 22. Then the forming wheel 23 will continue to squeeze the steel on the outer surface of the U-shaped block 2, thus automatically forming it.
