Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe fitting production equipment technology, specifically to a tooling for producing elbow pipe fittings. Background Technology
[0002] When processing small-diameter elbow pipe fittings, the pipe wall is relatively thin due to the small pipe diameter, making it more prone to deformation under stress. Therefore, horseshoe fittings are needed to support the inner diameter of the elbow pipe fittings to prevent deformation after stamping.
[0003] However, while horseshoe-shaped fittings can prevent deformation of elbow fittings during stamping, they can also become stuck to the elbow fittings during stamping, making removal particularly difficult. This often requires hammering the ends of the horseshoe-shaped fittings, taking anywhere from 10 to 20 minutes, and causing damage to the elbow fittings, necessitating further grinding and making them inconvenient to use. To address these issues, a tooling solution for elbow fitting production is proposed. Utility Model Content
[0004] In view of this, the present invention provides a tooling for the production of elbow pipe fittings. The present invention involves welding a positioning nut to the bottom of the horseshoe fitting and placing a protrusion against the bottom edge of the elbow pipe fitting. When the hydraulic rod drives the clamping arm to rise and fall, the protrusion can lift the edge of the elbow pipe fitting. At this time, the positioning nut welded to the bottom of the horseshoe fitting is blocked by the slide rail, and the horseshoe fitting is pulled out of the elbow pipe fitting by the pulling force of the hydraulic cylinder, so that the horseshoe fitting can be easily removed for convenient use.
[0005] To solve the above-mentioned technical problems, this utility model provides a tooling for producing elbow pipe fittings, including an elbow pipe fitting placed on an operating platform, a horseshoe-shaped fitting at the end of the elbow pipe fitting, a positioning nut welded to the bottom of the horseshoe-shaped fitting, a slide rail provided on the operating surface of the operating platform, the positioning nut slidingly engaging with the slide rail, a support plate centrally located at the top of the operating platform, a hydraulic cylinder fixedly mounted on the support plate, an adjustment component movably mounted at the lower end of the hydraulic cylinder, and a pair of movable clamping arms movably mounted at the bottom of the adjustment component, the bottom of the clamping arms fitting against the edge of the elbow pipe fitting.
[0006] The support plate has an opening for the hydraulic rod to move up and down. The lower end of the hydraulic cylinder passes through the opening and is equipped with a hydraulic rod. The hydraulic rod is used to connect the hydraulic cylinder to the connecting plate and also to drive the connecting plate to move up and down. The lower end of the hydraulic rod is equipped with a connecting plate, which is used to connect the hydraulic rod to the slide rail on the adjusting assembly, so that the slide rail moves when the hydraulic rod moves.
[0007] The adjustment assembly includes a slide rail connected to a connecting plate. The slide rail is used for the movement of the sliders. The groove of the slide rail faces the direction of the slider. A stop is fixedly installed in the middle of the slide rail. The stop is used to separate the two sliders and prevent them from sticking together. A slider is provided on each side of the stop. The slider is used to connect the clamping arm to the slide rail. The slider is also used to connect the clamping arm to the threaded screw. So when the threaded screw drives the slider to move, the clamping arm will also move. Each slider slides in contact with the slide rail. A limit plate is provided at both ends of the slide rail. The limit plate is used to prevent the slider from falling off the slide rail. The limit plate is also used to make threaded holes.
[0008] The adjustment assembly also includes a threaded hole through the center of each limiting plate. The threaded hole is used to install a threaded screw. Each threaded hole contains a threaded screw, which drives the slider to move within the slide rail. This causes the clamping arm connected to the slider to move the protrusion, allowing the two clamping arms to converge or separate. This supports the bottom edge of elbow fittings of different widths. Each threaded screw passes through the threaded hole on the same side and is connected to the slider.
[0009] The bottom of each slider is connected to the clamping arm on the same side. Each clamping arm has a protrusion on its bottom side wall. The protrusion is used to abut against the bottom edge of the elbow fitting. When the hydraulic rod drives the clamping arm to rise and fall, the protrusion can lift the edge of the elbow fitting. At this time, the positioning nut welded to the bottom of the horseshoe fitting is blocked by the slide rail. Thus, the horseshoe fitting is pulled out of the elbow fitting by the pulling force of the hydraulic cylinder. The protrusion is used to ensure that each protrusion faces the center of the slide rail.
[0010] One end of the horseshoe-shaped component is sloping, while the other end is flat. The flat end of the horseshoe-shaped component is welded to the positioning nut. The slide is convex in shape. The size of the positioning nut is larger than the upper size of the slide and smaller than the lower size of the slide, so that the positioning nut can only move horizontally in and out of the slide and cannot detach from the upper part of the slide.
[0011] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0012] 1. By welding the positioning nut to the bottom of the horseshoe-shaped fitting and by placing the protrusion against the bottom edge of the elbow fitting, when the hydraulic rod drives the clamping arm to rise and fall, the protrusion can lift the edge of the elbow fitting. At this time, the positioning nut welded to the bottom of the horseshoe-shaped fitting is blocked by the slide rail, and the horseshoe-shaped fitting is pulled out of the elbow fitting by the pulling force of the hydraulic cylinder, so that the horseshoe-shaped fitting can be easily removed for convenient use.
[0013] 2. The threaded screw is used to drive the slider to move within the slide rail, which in turn causes the clamping arm connected to the slider to move the protrusion, so that the two clamping arms can be brought together or separated, thereby supporting the bottom edge of elbow pipe fittings of different widths.
[0014] 3. The slide is convex in shape. The size of the positioning nut is larger than the upper size of the slide and smaller than the lower size of the slide, so that the positioning nut can only move horizontally in and out of the slide and cannot be detached from the upper part of the slide.

[0023] In use, by welding the positioning nut 103 to the bottom of the horseshoe-shaped fitting 102 and by pressing the protrusion 401 against the bottom edge of the elbow fitting 101, when the hydraulic rod 202 drives the clamping arm 400 to rise and fall, the protrusion 401 can lift the edge of the elbow fitting 101. At this time, the positioning nut 103 welded to the bottom of the horseshoe-shaped fitting 102 is blocked by the slide rail 104, and the horseshoe-shaped fitting 102 is pulled out from the elbow fitting 101 by the pulling force of the hydraulic cylinder 201, so that the horseshoe-shaped fitting 102 can be easily removed for convenient use.
[0024] This embodiment provides a tooling for the production of elbow pipe fittings.
[0025] like Figure 1 , 2 As shown in Figures 3 and 4: The support plate 200 has an opening 203 for the hydraulic rod 202 to move up and down. The lower end of the hydraulic cylinder 201 passes through the opening 203 and is equipped with the hydraulic rod 202. The hydraulic rod 202 is sealed to the hydraulic cylinder 201. The bottom of the hydraulic cylinder 201 is equipped with a bracket and is fixed to the support plate 200 by bolts. The hydraulic rod 202 is used to connect the hydraulic cylinder 201 to the connecting plate 204. The hydraulic rod 202 is also used to drive the connecting plate 204 to move up and down. The lower end of the hydraulic rod 202 is equipped with the connecting plate 204. The connecting plate 204 is fixed to the telescopic end of the hydraulic rod 202 by bolts. The connecting plate 204 is used to connect the hydraulic rod 202 to the slide rail 301 on the adjusting assembly 300, so that when the hydraulic rod 202 moves, the slide rail 301 also moves.
[0026] Its effect is as follows: the hydraulic rod 202 is used to connect the hydraulic cylinder 201 to the connecting plate 204, the hydraulic rod 202 is also used to drive the connecting plate 204 to move up and down, and the connecting plate 204 is used to connect the hydraulic rod 202 to the slide rail 301 on the adjusting assembly 300, so that when the hydraulic rod 202 moves, the slide rail 301 also moves.
[0027] like Figure 1 , 2 As shown in Figures 3, 4, and 5: The adjusting assembly 300 includes a slide rail 301 connected to the connecting plate 204. The top plane of the slide rail 301 is fixed to the connecting plate 204 by bolts. The slide rail 301 is used for the movement of the slider 303. The slot of the slide rail 301 faces the direction of the movement. A stop block 302 is fixedly provided in the middle of the slide rail 301. The stop block 302 is used to separate the two sliders 303 and prevent them from sticking together. A slider 303 is provided on each side of the stop block 302. The top of the slider 303 is connected to the top of the clamping arm 400. The parts can be welded together. The slider 303 is used to connect the clamping arm 400 to the slide rail 301. The slider 303 is also used to connect the clamping arm 400 to the threaded screw 306. So when the threaded screw 306 drives the slider 303 to move, the clamping arm 400 will also move. Each slider 303 is slidably engaged with the slide rail 301. A limit plate 304 is provided at both ends of the slide rail 301. The limit plate 304 is used to prevent the slider 303 from falling off the slide rail 301. The limit plate 304 is also used to open the threaded hole 305.
[0028] Its effects are as follows: the slide rail 301 is used for the movement of the slider 303, the stop block 302 is used to separate the two sliders 303 to prevent them from sticking together, the slider 303 is used to connect the clamping arm 400 to the slide rail 301, and the slider 303 is also used to connect the clamping arm 400 to the threaded screw 306, so that when the threaded screw 306 drives the slider 303 to move, the clamping arm 400 will also move accordingly, the limiting plate 304 is used to prevent the slider 303 from falling off the slide rail 301, and the limiting plate 304 is also used to open the threaded hole 305.
[0029] like Figure 1 , 3As shown in Figures 4 and 5: The adjustment assembly 300 also includes a threaded hole 305 through the middle of each limiting plate 304. The threaded hole 305 is used to install a threaded screw 306. The threaded hole 305 and the threaded screw 306 are threadedly matched. Each threaded hole 305 is provided with a threaded screw 306. The threaded screw 306 is used to drive the slider 303 to move within the slide rail 301, thereby causing the clamping arm 400 connected to the slider 303 to drive the protrusion 401 to move, so that the two clamping arms 400 can be brought together or separated, thereby supporting the bottom edge of the elbow fitting 101 of different widths. Each threaded screw 306 passes through the threaded hole 305 on the same side and is connected to the slider 303.
[0030] Its effect is as follows: the threaded screw 306 is used to drive the slider 303 to move within the slide rail 301, thereby causing the clamping arm 400 connected to the slider 303 to drive the protrusion 401 to move, so that the two clamping arms 400 can be brought together or separated, thereby supporting the bottom edge of the elbow pipe fitting 101 of different widths.
[0031] like Figure 3 , 4 As shown in Figure 5: The bottom of each slider 303 is connected to the clamping arm 400 on the same side. Each clamping arm 400 has a protrusion 401 on its bottom side wall. The protrusion 401 is welded to the clamping arm 400. The protrusion 401 is used to abut against the bottom edge of the elbow fitting 101. When the hydraulic rod 202 drives the clamping arm 400 to rise and fall, the protrusion 401 can lift the edge of the elbow fitting 101. At this time, the positioning nut 103 welded to the bottom of the horseshoe fitting 102 is blocked by the slide rail 104. Thus, the horseshoe fitting 102 is pulled out from the elbow fitting 101 by the pulling force of the hydraulic cylinder 201. The protrusion 401 is used to ensure that each protrusion 401 faces the center of the slide rail 104.
[0032] Its effect is as follows: the protrusion 401 is used to abut against the bottom edge of the elbow fitting 101, so that when the hydraulic rod 202 drives the clamping arm 400 to rise and fall, the protrusion 401 can lift the edge of the elbow fitting 101. At this time, the positioning nut 103 welded to the bottom of the horseshoe fitting 102 is blocked by the slide 104, so that the horseshoe fitting 102 is pulled out from the elbow fitting 101 by the pulling force of the hydraulic cylinder 201.

The flat end of the horseshoe-shaped component 102 is welded to the positioning nut 103. The slide rail 104 is convex in shape. The size of the positioning nut 103 is larger than the upper size of the slide rail 104 but smaller than the lower size of the slide rail 104, so that the positioning nut 103 can only move horizontally in and out of the slide rail 104 and cannot detach from the upper part of the slide rail 104.
[0034] The effect is that the slide 104 is convex in shape, and the size of the positioning nut 103 is larger than the upper size of the slide 104 but smaller than the lower size of the slide 104, so that the positioning nut 103 can only move horizontally in and out of the slide 104 and cannot be disengaged from the upper part of the slide 104.
[0035] Working principle: By welding the positioning nut 103 to the bottom of the horseshoe-shaped part 102 and by pressing the protrusion 401 against the bottom edge of the elbow pipe fitting 101, when the hydraulic rod 202 drives the clamping arm 400 to rise and fall, the protrusion 401 can lift the edge of the elbow pipe fitting 101. At this time, the positioning nut 103 welded to the bottom of the horseshoe-shaped part 102 is blocked by the slide rail 104. Thus, the horseshoe-shaped part 102 is pulled out from the elbow pipe fitting 101 by the pulling force of the hydraulic cylinder 201, making it easy to remove the horseshoe-shaped part 102 for convenient use. Moreover, using this tooling, the problem of the horseshoe-shaped part 102 being difficult to remove can be solved in just 2 minutes, reducing product damage and saving manpower.
