Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel pipe processing technology, specifically to a shaping and forming device for steel pipe processing. Background Technology
[0002] In the process of mechanical production and construction, steel pipes need to be connected in different positions through welding, clamping, and pin limiting. In the process of butt welding of steel pipe ends, the pipe diameters of the steel pipes must match each other and the end faces must be flat to ensure the accuracy of the connection. However, in the actual processing and production process, the pipe ends of steel pipes are easily deformed due to bumps and knocks during handling, storage and processing. The deformed pipe end structure is damaged and irregular, which will lead to a decrease in the accuracy of the connection and a decrease in the fit of the pipe ends during the connection.
[0003] As disclosed in Chinese Patent Publication No. CN218224126U, a shaping device for steel pipe processing is first placed into the steel pipe by connecting the sliding sleeve and the movable rod. During this process, the movable rod can adapt to the size of the deformed pipe opening by rotating itself. When the clamping seat engages with the end of the steel pipe, the ball moves to the position of contacting the inner wall of the deformed steel pipe. At this time, the clamping device can be adjusted to clamp the outer wall of the steel pipe. Finally, the drive motor is turned on, which drives the screw to rotate, thereby driving the entire assembly of the sliding sleeve, movable rod, ball, and limiting ring to rotate along a spiral path inside the steel pipe. During this process, the assembly of the ball and movable rod will tend to rotate away from the support plate due to the relative friction with the inner wall of the steel pipe. At this time, the limiting ring can prevent the movable rod from tilting, so that the ball can always roll along the inner wall of the steel pipe, thereby achieving the effect of gradually rounding the pipe opening.
[0004] However, the steel pipe processing shaping device in the above application uses ball bearings to shape the inner wall of the steel pipe. However, when dealing with steel pipes with thick walls and high strength, simply relying on the rolling of ball bearings may not be able to shape them well. Therefore, it has certain limitations.
[0005] Therefore, we urgently need to provide a shaping and forming device for steel pipe processing. Utility Model Content
[0006] The purpose of this utility model is to provide a shaping and forming device for steel pipe processing, so as to solve the problem of the shaping and forming device for steel pipe processing mentioned in the background art, which uses ball bearings to shape the inner wall of the steel pipe. However, when dealing with steel pipes with thick walls and high strength, the method of simply relying on the rolling of ball bearings may not be able to shape them well.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a shaping device for steel pipe processing, comprising a processing table and support legs, wherein the four support legs are respectively fixedly connected to the four corners of the lower surface of the processing table, and a softening device and a shaping device are provided on the upper surface of the processing table.
[0008] The softening device includes a placement unit and a softening unit.
[0009] The placement unit includes a base, a placement cylinder, and a steel pipe. The base is fixedly connected to the right side of the upper surface of the processing table, the placement cylinder is fixedly connected to the top of the base, and the steel pipe is placed inside the placement cylinder. Simply place the steel pipe inside the placement cylinder.
[0010] A further improvement is that the softening unit includes an electric cylinder, an arc-shaped clamping plate, and an electric heating plate. The electric cylinder is installed on the outside of the placement cylinder, with its inner end extending into the interior of the placement cylinder. The arc-shaped clamping plate is fixedly connected to the inner end of the electric cylinder, and the electric heating plate is installed inside the arc-shaped clamping plate. When the electric cylinder is activated, it drives the arc-shaped clamping plate to clamp and fix the steel pipe in the center of the placement cylinder. Then, the electric heating plate is activated to heat the steel pipe, making it slightly soft and easier to shape.
[0011] A further improvement is that the inner wall of the arc-shaped clamping plate is made of copper plate, which has good thermal conductivity and is more conducive to the rapid heating and softening of the steel pipe, thus improving the efficiency of shaping. There are three sets of softening units, which are installed in a ring on the outside of the placement cylinder, thereby clamping the steel pipe in the center of the placement cylinder.
[0012] A further improvement is that the shaping device includes a moving unit, a rotating unit, and a shaping unit.
[0013] The moving unit includes an electric guide rail, a guide rail seat, a support rod, and a mounting base. The electric guide rail is installed on the left side of the upper surface of the processing table. The guide rail seat is slidably connected to the electric guide rail. The support rod is fixedly connected to the top of the guide rail seat. The mounting base is fixedly connected to the top of the support rod. The guide rail seat is driven to move from left to right on the electric guide rail, thereby driving the shaping unit on its top mounting base to move from the inside to the outside of the steel pipe and shape it.
[0014] A further improvement is that the rotating unit includes a drive motor, a rotating shaft, and a turntable. The drive motor is installed on the top left side of the mounting base. The left end of the rotating shaft is connected to the output end of the drive motor. The turntable is fixedly connected to the right end of the rotating shaft. When the drive motor is started, it drives the rotating shaft to rotate, which in turn drives the turntable on its right end to rotate, which in turn drives the shaping unit to rotate, thus shaping the inner wall of the steel pipe.
[0015] A further improvement is that a support frame is installed on the right side of the mounting base, and a fixed bearing is installed inside the support frame. The rotating shaft is rotatably connected to the inside of the fixed bearing. The right side of the turntable has four mounting slots arranged in a ring shape, so that the rotating shaft rotates stably inside the fixed bearing, thereby improving the stability of the device.
[0016] A further improvement is that the shaping unit includes an electric telescopic rod, a ball head seat, and a ball bearing. The electric telescopic rod is installed inside the mounting groove, the ball head seat is installed at the outer end of the electric telescopic rod, and the ball bearing is rotatably connected to the inside of the ball head seat. When the electric telescopic rod is activated, it drives the ball bearing at its outer end to move outward to contact the inner wall of the steel pipe, thereby adapting to steel pipes of different diameters and improving the applicability of the device. When the turntable rotates, it drives the ball bearing to rotate inside the ball head seat, thereby shaping the inner wall of the steel pipe to achieve the effect of a perfectly round pipe opening.
[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. The steel pipe processing shaping device simultaneously starts three electric cylinders, thereby driving three arc-shaped clamping plates to clamp and fix the steel pipe in the center of the placement cylinder. Then, the electric heating plate is activated to heat the steel pipe, making it slightly softer and easier to shape.
[0018] 2. This steel pipe processing shaping device starts the electric telescopic rod, which drives the outer end of the ball to move outward to contact the inner wall of the steel pipe, thereby adapting to steel pipes of different diameters and improving the applicability of the device. In conjunction with the rotating unit, it drives the turntable to rotate, thereby driving the ball to rotate inside the ball head seat, thereby shaping the inner wall of the steel pipe to achieve the effect of a perfectly round pipe end.
