However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 5As shown, the utility model provides a complete set of fan-shaped tube forming molds, including: a mounting seat 1, a front surface of the mounting seat 1 is equidistantly fixedly connected with a plurality of fixed blocks 2, the outer surfaces of the plurality of fixed blocks 2 are respectively provided with electric telescopic rods 3, the telescopic ends of the plurality of electric telescopic rods 3 respectively slide through the outer surfaces of the plurality of fixed blocks 2, the telescopic ends of the plurality of electric telescopic rods 3 are respectively fixedly connected with a mold body 4, and the rear surfaces of the plurality of mold bodies 4 are respectively symmetrically provided with fixing holes 9; a limiting component 7, the limiting component 7 includes a mounting frame 701, the mounting frame 701 is fixedly connected to the inner surface of the mounting seat 1, a plurality of pushing blocks 704 are equidistantly arranged on the inner side of the mounting frame 701, the inner surfaces of the plurality of pushing blocks 704 are respectively symmetrically fixedly connected with connecting rods 703, the rear end surfaces of the plurality of connecting rods 703 are all fixedly connected with connecting frames 705, and the plurality of The outer surfaces of the connecting rods 703 slide through the mounting frame 701 and the rear surface of the mounting seat 1 in sequence, the connecting rods 703 and the fixing holes 9 are matched, and the outer surface of the connecting rods 703 is sleeved with a spring 702 near the rear surface of the pushing block 704, and the spring 702 is located on the inner side of the mounting frame 701, the rear surface of the mold body 4 fits with the front surface of the mounting seat 1, and the outer surface of the mold body 4 fits with the outer surface of the fixing block 2. The outer surfaces of multiple mold bodies 4 fit, and the inner surface of one of the mold bodies 4 is arc-shaped. The rear surface of the mounting seat 1 is fixedly connected with a guide block 5 near the center, and a guide hole 8 is opened on the rear surface of the guide block 5. The rear end face of the connecting rod 703 is fixedly connected with a contact block 708, and the contact block 708 is hemispherical. The outer surface of the contact block 708 is slidably connected to the rear surface of the mounting seat 1.

[0025] The effect achieved by the entire embodiment 1 is that when the fan-shaped tube is formed and manufactured, the handle 706 is held and pulled toward the rear side of the mounting seat 1, and the multiple connecting rods 703 are pulled through the connecting frame 705, and then the multiple pushing blocks 704 will squeeze the multiple springs 702 respectively, causing them to deform and shrink, and the connecting rods 703 and the contact blocks 708 will shrink into the mounting frame 701 and slide out from the multiple corresponding fixing holes 9 respectively, releasing the limit of the multiple mold bodies 4, and while keeping pulling the connecting frame 705, the multiple When the telescopic ends of the multiple electric telescopic rods 3 slide and retract in the fixed block 2, the multiple mold bodies 4 are simultaneously dispersed to the surroundings to increase the gap in the center. At this time, the square tube for modification is inserted so that its front end contacts the center of the front surface of the mounting seat 1. The telescopic ends of the multiple electric telescopic rods 3 are synchronously reset and extended outward. The multiple mold bodies 4 will squeeze the surface of the square tube. Due to the lack of support inside the square tube, the front end of the square tube will easily deform to form a smaller cross-section. Repeat the above operation until the front end of the square tube can be After the plurality of mold bodies 4 are compounded and fitted together, the pulling of the connecting frame 705 is released, and the plurality of springs 702, under the elastic reset action, will squeeze and push the rear surfaces of the plurality of push blocks 704 respectively, and the plurality of connecting rods 703 and the contact blocks 708 will be respectively inserted into the corresponding fixing holes 9 to limit and fix the plurality of mold bodies 4. At this time, the fan-shaped mold block is inserted at the center of the square tube, so that the square tube is in the fan-shaped mold block and the plurality of mold bodies. The traction mechanism only needs to pull the front end of the clamped square tube to re-draw the square tube to form a fan-shaped tube with curved corners. The telescopic ends of multiple electric telescopic rods 3 respectively drive multiple mold bodies 4 to move synchronously, which plays a role in squeezing the front end of the square tube, causing the front end of the square tube to be deformed and contracted, making it easier for the square tube to be inserted into the guide hole 8. After being clamped and fixed by the traction mechanism, it is pulled and cold-drawn to form a fan-shaped tube, avoiding the need for personnel to manually hammer the front end of the square tube, thereby reducing the work intensity of personnel.

[0026] Embodiment 2, as Figure 1-Figure 5 As shown, handles 706 are fixedly connected to the outer surfaces of both sides of the connecting frame 705, and multiple grooves 707 are equidistantly formed on the outer surfaces of the two handles 706. Avoidance grooves 6 are symmetrically formed on the rear surface of the mounting base 1, and the avoidance grooves 6 are matched with the handles 706.

[0027] The effect achieved by the entire embodiment 2 is that, when in use, a plurality of grooves 707 are equidistantly provided on the outer surface of the handle 706 to increase the friction force, and avoidance grooves 6 are symmetrically provided on the rear surface of the mounting base 1 near the two handles 706, so that when a person holds the handle 706, he can better hold the handle 706, avoiding the handle 706 from being too close to the mounting base 1, resulting in a small distance between the handle 706 and the mounting base 1, making it difficult to hold, thereby improving the use effect of the entire set of fan-shaped tube forming molds.

[0028] Working principle: when in use, by pulling the handle 706 backward, the connecting frame 705 drives the multiple connecting rods 703 to move backward, and then the multiple pushing blocks 704 will squeeze the multiple springs 702 respectively, causing them to deform and shrink, and the connecting rods 703 will slide out of the multiple fixing holes 9, releasing the limit fixation of the multiple mold bodies 4, and synchronously starting the multiple electric telescopic rods 3. The telescopic ends of the multiple electric telescopic rods 3 drive the multiple mold bodies 4 to move synchronously, and the multiple mold bodies 4 are dispersed to the surroundings to increase the gap in the center, which is convenient for the square tube to be pulled out. The front end contacts the center of the front surface of the mounting seat 1, and the telescopic ends of the multiple electric telescopic rods 3 are synchronously reset and stretched outward. The multiple mold bodies 4 will squeeze the surface of the square tube. Due to the lack of support inside the square tube, the front end of the square tube will easily deform to form a smaller cross-section, and the above operation is repeated until the front end of the square tube can be inserted into the guide hole 8 and protrude from the guide block 5. The rear surface of the square tube is convenient for being clamped and fixed by the traction mechanism, and the pulling on the connecting frame 705 is released. Under the elastic reset action, the multiple springs 702 will squeeze and push the rear surfaces of the multiple pushing blocks 704 respectively. The contact blocks 708 fixed on the front end faces of the multiple connecting rods 703 will contact the rear surface of the mold body 4, and after the multiple mold bodies 4 are reset, they will rub against it until they slide into the corresponding fixing holes 9, and the multiple mold bodies 4 are limited and fixed. The traction mechanism only needs to pull the front end of the clamped square tube to cold-draw the square tube to form a fan-shaped tube with curved corners. The telescopic ends of the multiple electric telescopic rods 3 drive the multiple mold bodies 4 to move synchronously, which plays a role in squeezing the front end of the square tube to cause deformation and contraction, so that the square tube is convenient to insert into the guide hole 8. After being clamped and fixed by the traction mechanism, it is pulled and cold-drawn to form a fan-shaped tube, which avoids the need for personnel to manually hammer the front end of the square tube, thereby reducing the work intensity of the personnel.
