[0001] This utility model relates to the field of machining equipment, specifically a steel pipe flaring device. Background Technology

[0002] When connecting steel pipes of different diameters, one end of the pipe needs to be flared. A conventional pipe flaring device includes a flaring mold and a heating device for heating the pipe. Using this device, one end of the pipe is aligned with the flaring mold, and the heating mechanism simultaneously heats it, thus completing the flaring process. However, this process heats both the pipe and the mold simultaneously, increasing the heating time and wasting energy. Utility Model Content

[0004] The technical solution of this utility model is as follows: A steel pipe flaring device includes a worktable, a heating mechanism, a clamping mechanism, and a top-feeding mechanism. One end of the worktable is provided with a mold base, on which a mold for fitting the steel pipe is mounted; the mold and mold base are detachably connected. A deflectable heating mechanism is provided on the side of the worktable near the mold base. The heating mechanism includes a heating ring, a rotating rod, and a fixing rod. One end of the rotating rod is fixedly connected to the heating ring, and the other end is rotatably connected to the top of the fixing rod, the other end of which is fixedly connected to the worktable. A top-feeding mechanism is provided on the other side of the worktable, and a clamping mechanism is provided on the side of the worktable near the top-feeding mechanism.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] The specific embodiments of this utility model will now be described with reference to the accompanying drawings:

[0023] like Figures 1-6 As shown, a steel pipe flaring device includes a worktable 1, a heating mechanism 2, a clamping mechanism 3, and a top-feeding mechanism 4. A mold base 12 is provided at one end of the worktable 1, and a mold 13 that mates with the steel pipe is provided on the mold base 12. The mold 13 is detachably connected to the mold base 12. A groove for mates with the mold 13 is provided on the mold base 12, and a through hole is provided at the bottom of the groove. A bolt 131 is provided at one end of the mold 13 near the mold base 12. The bolt 131 passes through the through hole and is screwed into the mold base 12. The detachable connection between the mold 13 and the mold base 12 via the bolt 131 facilitates the replacement of different molds 13 to flare the steel pipe at different angles or depths.

[0024] A deflectable heating mechanism 2 is provided on the side of the workbench 1 near the mold base 12. The heating mechanism 2 includes a heating ring, a rotating rod 22, and a fixed rod 23. One end of the rotating rod 22 is fixedly connected to the heating ring, and the other end is rotatably connected to the top of the fixed rod 23. The other end of the fixed rod 23 is fixedly connected to the workbench 1. The position of the heating ring can be flexibly adjusted by the rotating rod 22. When the steel pipe needs to be heated, the rotating rod 22 is deflected to the front of the mold 13, and the steel pipe moves into the heating ring, where it is heated by electromagnetic induction. During the heating process, the mold 13 does not need to be heated, saving energy and improving the efficiency of heating the steel pipe. When heating is not needed, the steel pipe is moved back, and the rotating rod 22 is deflected away from the front of the mold 13, facilitating the subsequent flaring process of the steel pipe. A knob 222 is provided at the connection between the rotating rod 22 and the fixed rod 23. The tightness of the connection between the rotating rod 22 and the fixed rod 23 is adjusted by the knob 222, so that the rotating rod 22 drives the heating ring to a fixed state. The fixed rod 23 is equipped with a limiting block 223 that cooperates with the rotating rod 22. The limiting block 223 helps the rotating rod 22 to drive the heating ring to rotate quickly to the position directly in front of the mold 13. The pull ring 221 on the rotating rod 22 facilitates the operation of the rotating rod 22.

[0025] A top-feeding mechanism 4 is provided on the other side of the worktable 1, and a clamping mechanism 3 is provided on the side of the worktable 1 near the top-feeding mechanism 4. The top-feeding mechanism 4 includes a fixed plate 14 and a top rod. The fixed plate 14 is fixedly connected to the worktable 1. One end of the top rod is provided with a handwheel 41, and the other end passes through the fixed plate 14 and is threadedly connected to the fixed plate 14. The end of the top rod near the steel pipe is provided with a rotatably connected top plate 42. Rotating the handwheel 41 causes the top rod to drive the top plate to apply external force to the end of the steel pipe, causing the steel pipe to move towards the mold 13. A magnetic strip 421 is provided on the contact surface between the top plate 42 and the steel pipe. After the steel pipe is heated, the top-feeding mechanism 4 can drive the steel pipe to move away from the mold 13 through the magnetic strip 421.

[0026] The clamping mechanism 3 includes a base 32 and clamping plates, the clamping plates including an upper clamping plate 311 and a lower clamping plate 33. The upper clamping plate 311 is movably connected to the upper part of the base 32, and the lower clamping plate 33 is elastically connected to the lower part of the base 32. The upper clamping plate 311 and the lower clamping plate 33 cooperate to clamp the steel pipe, keeping the steel pipe and the mold 13 on the same axis. The clamping plate is V-shaped, and multiple rotatably connected rollers 333 are provided on the surface of the clamping plate near the steel pipe. The V-shaped clamping plate facilitates clamping steel pipes of different diameters. The clamping plate maintains rolling contact with the steel pipe through the rollers 333, preventing scratches from occurring between the steel pipe and the clamping plate during the movement of the steel pipe towards the mold 13. A cylinder 31 is provided on the upper part of the base 32, and the telescopic end of the cylinder 31 passes through the upper part of the base 32 and is fixedly connected to the upper clamping plate 311. A positioning groove 321 is provided on the lower part of the base 32, and multiple positioning holes 322 are provided at the bottom of the positioning groove 321, each positioning hole 322 containing a spring 323. The lower clamping plate 33 is provided with a positioning block 332 that mates with the positioning groove 321 and a positioning post 331 that mates with the positioning hole 322. The lower end of the spring 323 is connected to the positioning hole 322, and the upper end contacts the positioning post 331. During the clamping process, steel pipes of different diameters may deviate from the axis corresponding to the mold 13. The height-adjustable lower clamping plate 33 makes it easy for the clamping mechanism 3 to keep steel pipes of different diameters on the same axis as the mold 13 when fixing the steel pipes.

[0027] The working principle of this utility model is as follows: The steel pipe is clamped and fixed on the clamping mechanism 3. The top-feeding mechanism 4 applies external force to one end of the steel pipe, causing the steel pipe to move into the heating ring. After heating is completed, the top-feeding mechanism 4 moves the steel pipe backward through the magnetic strip 421, displaces the heating ring from the front of the mold 13, and then pushes the steel pipe back towards the mold 13, causing the steel pipe to undergo flaring deformation.
