[0002] Metal pipe fittings are a type of metal product widely used in various fields. They are typically made of metal materials such as copper, iron, aluminum, and stainless steel, and feature high strength, good toughness, and corrosion resistance. They come in various shapes, including straight pipes, bends, tees, and crosses, to meet different pipeline system connection and fluid transportation needs. In the construction industry, they are used for water supply and drainage and heating systems; in the chemical industry, they can transport various corrosive media; and in machinery manufacturing, they are key components of hydraulic and pneumatic systems. Metal pipe fittings are manufactured through various processing techniques such as casting, forging, and welding, and their quality and performance directly affect the operating efficiency and safety of the entire system.

[0023] Please see Figure 1-4 This utility model provides a new technical solution: a metal pipe flaring and shrinking device, including a processing table 1, an L-shaped plate 2 fixedly installed on the upper surface of the processing table 1, a clamping mold 3 fixedly installed on the upper surface of the processing table 1 by bolts, the clamping mold 3 being located at the lower end of the L-shaped plate 2, and a shrinking mold 4 being provided at the left end of the upper surface of the processing table 1.

[0024] An auxiliary adjustment mechanism is installed on the processing table 1. The auxiliary adjustment mechanism includes a U-shaped plate 5 and two clamping plates 6. Two fixing plates 7 are fixedly installed on the right end of the upper surface of the processing table 1. Adjustment electric push rods 8 are fixedly installed on the right surface of each of the two fixing plates 7. The left ends of the two adjustment electric push rods 8 pass through to the left side of the two fixing plates 7 respectively. The U-shaped plate 5 is fixedly installed on the telescopic ends of the two adjustment electric push rods 8. The U-shaped plate 5 slides in contact with the upper surface of the processing table 1. Two clamping electric push rods 9 are fixedly installed on the upper and lower surfaces of the U-shaped plate 5. The near ends of the four clamping electric push rods 9 pass through the interior of the U-shaped plate 5. The two clamping plates 6 are fixedly installed on the telescopic ends of the two clamping electric push rods 9 on the upper side and the two clamping electric push rods 9 on the lower side respectively.

[0025] Furthermore, the auxiliary adjustment mechanism also includes two rubber pads 10, which are respectively fixedly installed on the adjacent surfaces of the two clamping plates 6.

[0026] Furthermore, by clamping the metal pipe fittings with two clamping plates 6 and then adjusting the metal pipe fittings with two electric push rods 8, the exposed length of the metal pipe fittings can be adjusted more precisely, thereby ensuring the dimensional accuracy of the processed pipe fittings, improving work efficiency, reducing errors and labor intensity caused by manual adjustment, and improving the processing efficiency of metal pipe fittings.

[0027] Furthermore, two slide rails 11 are fixedly installed on the left end of the upper surface of the processing table 1. A first mounting plate 12 is slidably installed on the upper end of the two slide rails 11. A slider 13 is slidably installed on the right surface of the first mounting plate 12. The necking mold 4 is fixedly installed on the right surface of the slider 13 by bolts.

[0028] Furthermore, a second mounting plate 14 is fixedly installed on the left end of the upper surface of the processing table 1, and a first cylinder 15 is fixedly installed on the left surface of the second mounting plate 14. The right end of the first cylinder 15 extends through to the right side of the second mounting plate 14, and the first cylinder 15 is fixedly connected to the first mounting plate 12.

[0029] Furthermore, a second cylinder 16 is fixedly installed on the upper surface of the L-shaped plate 2. The lower end of the second cylinder 16 extends through to the upper surface of the clamping mold 3, and the telescopic end of the second cylinder 16 is fixedly installed on the upper surface of the upper mold of the clamping mold 3.

[0030] Furthermore, rectangular slots 17 are provided on the right end of the upper surface of the processing table 1, corresponding to the positions of the two clamping electric push rods 9 on the lower side.

[0031] Furthermore, when using this device, the necking mold 4 can be replaced as needed for necking or flaring. When necking, first place the metal pipe to be necked in the clamping mold 3, ensuring the left end of the metal pipe is flush with the left surface of the clamping mold 3. Then, activate the two adjusting electric push rods 8 to push the U-shaped plate 5, so that the right end of the metal pipe is positioned between the two clamping plates 6. Activate the four clamping electric push rods 9; the two upper clamping electric push rods 9 and the two lower clamping electric push rods 9 respectively push the corresponding clamping plates 6 closer to the metal pipe until the two clamping plates 6 clamp the metal pipe. At this point, the rubber pad 10 contacts the surface of the metal pipe. Adjust the exposed length of the metal pipe as needed, and activate the two adjusting electric push rods 8 to adjust the extension of the telescopic ends of the electric push rods 8. The U-shaped plate 5, clamping plate 6, and the clamped metal pipe are moved to the left together. When the exposed length of the metal pipe is adjusted to the specified position, the electric push rod 8 is stopped. Then, the upper mold of the clamping mold 3 is pushed downward by the second cylinder 16, thereby firmly clamping the metal pipe in the clamping mold 3 to ensure that the pipe will not move during processing. Then, the four clamping electric push rods 9 are released to separate the clamping plate 6 from the metal pipe. At this time, the first cylinder 15 can be started to push the first mounting plate 12 to move to the right along the slide rail 11, so that the necking mold 4 installed on the slider 13 gradually approaches the clamped metal pipe. As the necking mold 4 applies pressure to the metal pipe, the end of the metal pipe undergoes plastic deformation under the action of the necking mold 4 to achieve necking. The flaring process is the same as the above process.

[0032] Structural Description: Processing Table 1: As the basic support component of the entire device, it provides an installation platform for other parts, ensuring the accurate relative position of each part and ensuring the stability and reliability of the processing process;

[0033] L-shaped plate 2: Fixedly installed on the processing table 1, providing an installation position for the second cylinder 16. The second cylinder 16 drives the upper mold of the clamping mold 3 to move, thereby realizing the clamping and releasing operation of the metal pipe.

[0034] Clamping mold 3: It is fixed to the processing table 1 by bolts and is used to clamp the metal pipe fittings to keep them fixed during the processing, prevent the pipe fittings from moving and affecting the processing accuracy, and ensure that the shrinking or flaring operation is carried out smoothly.

[0035] Narrowing mold 4: Set at the left end of the processing table 1, it is used to narrow the metal pipe fittings. It is connected to the slider 13 by bolts. Under the action of the electric slide rail and the first cylinder 15, it can contact, apply pressure and reset with the pipe fittings. The narrowing mold 4 can be replaced with an flaring mold according to the processing requirements.

[0036] U-shaped plate 5: It is the main body of the auxiliary adjustment mechanism and is connected to the electric adjustment push rod 8. Under its push, it can slide on the processing table 1, driving the clamping plate 6 and the pipe to move, so as to adjust the exposed length of the pipe.

Two electric slide rails are mounted vertically parallel on the right surface of the first mounting plate 12. Slider 13 is mounted on the two electric slide rails and moves along slide rail 11 under the action of first cylinder 15, causing reducing mold 4 to move closer to or away from the pipe fitting.

[0044] Slider 13: Installed on the electric slide rail of the first mounting plate 12, it drives the shrinking mold 4 to move back and forth, so that the shrinking mold 4 accurately contacts the pipe and applies pressure to complete the shrinking process;

[0045] Second mounting plate 14: fixed on the processing table 1, providing a mounting position for the first cylinder 15, ensuring the stability of the first cylinder 15 during operation, and enabling it to effectively push the first mounting plate 12 to move;
