Description

Technical Field

[0001] The utility model relates to the technical field of metal piece processing, and more specifically to a nut tube forming and shaping device. Background Art

[0002] Nut pipes are commonly used in pipe connections. They consist of a nut and pipe. They primarily secure and seal pipes during connection, preventing them from loosening and leaking. Nut pipes are categorized by their connection method as either internally threaded or externally threaded. Internally threaded nut pipes typically connect to externally threaded pipes, while externally threaded nut pipes connect to internally threaded pipes. They can be made of steel, copper, or stainless steel, depending on the material used.

[0003] In the process of forming the two ends of the nut tube, the commonly used shrinking processing equipment uses a cylinder to drive the forming sleeve to shrink the two ends of the nut tube. However, when using the existing shaping equipment, only a flat pressure plate or a clamp is used to limit and fix the pipe fittings. Not only is the stability poor, but the pipe fittings are prone to slipping. In addition, it is not suitable for stable positioning of pipe fittings of different diameters, which affects the quality of pipe fitting processing. Utility Model Content

In addition, the forms of the various structures recorded in the following embodiments are merely examples. The nut tube forming and shaping device involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Reference Figure 1-5 The utility model provides a nut tube forming and shaping device, including a base plate 1, the upper surface of the base plate 1 is provided with two strip guide holes 2 with mutually symmetrical positions, the inner walls of the two strip guide holes 2 are rotatably connected with a bidirectional screw rod 11, the surface of the bidirectional screw rod 11 is threadedly connected with two movable bottom blocks 4, and the upper surface of the movable bottom block 4 is fixedly connected with a movable seat 5.

[0028] An adjusting motor 16 is fixedly provided on the left side of the base plate 1 . The output shaft of the adjusting motor 16 extends into the interior of the strip-shaped guide hole 2 and is fixedly connected to the left end of the bidirectional lead screw 11 .

[0029] Through the above technical solution, the adjusting motor 16 can be used to drive the bidirectional screw 11 to rotate, thereby driving the two movable bottom blocks 4 to move in the strip guide hole 2, and then driving the movable seat 5 to move in the opposite direction on the surface of the bottom plate 1, thereby adjusting the distance between the two movable seats 5.

[0030] It needs to be further explained that a fixed bar 6 is fixedly provided on the upper surface of the movable seat 5, and a first pneumatic push rod 7 is fixedly installed on the side surface of the two fixed bars 6 away from each other, and the telescopic end of the first pneumatic push rod 7 is fixedly connected to the mounting seat 8, and two guide slides 17 are fixedly connected to the side of the mounting seat 8. A guide through hole is opened on the surface of the fixed bar 6, and the guide slide 17 is slidably connected to the fixed bar 6 through the guide through hole. Two movable push rods 9 are fixedly installed on the side of the mounting seat 8, and a forming sleeve head 10 is fixedly installed on the end of the movable push rod 9.

[0031] It should be noted that the inner diameter of the forming sleeve head 10 is slightly smaller than the outer diameter of the nut tube, so the forming sleeve head 10 can be used to form both ends of the nut tube.

[0032] The upper surface of the movable seat 5 is fixedly connected to the limiting mechanism 3, and the limiting mechanism 3 includes a support block 301. The upper surface of the support block 301 is provided with two rectangular guide grooves 302. The front and rear inner walls of the rectangular guide groove 302 are provided with limiting slide grooves 303. The inner wall of the limiting slide groove 303 is slidably connected with a trapezoidal clamping block 304. The two trapezoidal clamping blocks 304 are symmetrically distributed inside the rectangular guide groove 302, and the inclined surfaces of the two trapezoidal clamping blocks 304 are close to each other.

[0033] Through the above technical solution, a cylindrical groove 305 is opened on the inner wall of the limiting slide 303, and a clamping column 306 is slidably provided on the inner wall of the cylindrical groove 305. One end of the clamping column 306 is fixedly connected to the surface of the trapezoidal clamping block 304, and a support spring 307 is fixedly connected to the inner wall of the cylindrical groove 305. The end of the clamping column 306 away from the trapezoidal clamping block 304 is fixedly connected to the end of the support spring 307. By arranging two trapezoidal clamping blocks 304 and support springs 307 on the surface of the support block 301, it is suitable for limiting and fixing nut tubes of different diameters.

[0034] It is worth noting that by arranging two movable seats 5 on the surface of the base plate 1, the limiting mechanisms 3 on the surfaces of the two movable seats 5 can be used to limit and fix the two ends of the nut tube, and the two first pneumatic push rods 7 can be used at the same time to drive the forming sleeve head 10 to perform forming processing on the two ends of the nut tube, which is beneficial to improve the stability of the nut tube during the forming process.

[0035] Four columns 12 are fixedly connected to the upper surface of the movable seat 5, and the top ends of the four columns 12 are fixedly connected to a top plate 13. A second pneumatic push rod 14 is fixedly installed on the upper surface of the top plate 13.

[0038] It is worth noting that by opening a trapezoidal groove 1501 on the lower surface of the pressing block 15, and providing an arc-shaped top block 1505 and a buffer groove 1503 inside the trapezoidal groove 1501, when limiting the nut tube, the pressing block 15 can drive the trapezoidal groove 1501 to wrap the nut tube, and the compression spring 1504 inside the buffer groove 1503 can be used to drive the arc-shaped top block 1505 to limit and support the top of the nut tube, thereby playing an anti-slip role, thereby improving the stability of the nut tube during the shaping process.

[0039] Working principle: First, adjust and position the distance between the two movable seats 5 according to the length of the nut tube, and then place the two ends of the nut tube between the two trapezoidal clamping blocks 304 in the rectangular guide groove 302 on the surface of the support block 301, and then use the second pneumatic push rod 14 to drive the pressing block 15 to move downward, and use the trapezoidal groove on the lower surface of the pressing block 15 to limit and fix the top of the 1501 nut tube, and then use the left and right two first pneumatic push rods 7 to drive the movable push rod 9 to move, and then drive the forming sleeve head 10 to extrude and form the two ends of the nut tube, thereby completing the shaping process of the nut tube.
