By replacing the mold, pipe end processing and forming such as expanding, shrinking, bulging and upsetting the rib of the pipe fitting can be carried out;

[0003] Among them, a taper pipe shrinking machine for steel pipes proposed in the prior art with the authorization announcement number CN210676684U includes a pipe shrinking machine body, an upper clamping block and a lower clamping block. A regulating mechanism is arranged on the right side of the top of the pipe shrinking machine body. The regulating mechanism includes a bottom plate, two limiting rods, a top plate and a threaded rod.

The two ends of the threaded rod are respectively connected to the middle of the top of the bottom plate and the middle of the top of the top plate. A concave frame is arranged on the outer part of the threaded rod;

[0004] In the prior art, the steel pipe cannot be rotated and compressed, so the steel pipe cannot be processed more smoothly and flatly. The equipment has high requirements for the size of the compressed steel pipe and cannot quickly adjust the steel pipes to be compressed with different sizes. Therefore, we propose a taper pipe shrinking machine for steel pipes. Content of the Utility Model

[0008] Moving unit: It includes an arc-shaped groove support plate, a first electric telescopic rod, a threaded rod, a fixed support block, a mounting block, and a first motor. The front side of the upper end of the base plate is fixedly connected with a mounting block, the rear side of the upper end of the base plate is fixedly connected with a fixed support block, the front end of the mounting block is fixedly connected with a first motor, one end of the output shaft of the first motor is fixedly connected with one end of the threaded rod, the other end of the threaded rod is rotatably connected with the fixed support block, the threaded rod is threadedly connected with the upper end of the dovetail-shaped slider, the left and right sides of the upper end of the mounting block are fixedly connected with two first electric telescopic rods, and the upper end of the first electric telescopic rod is fixedly connected with an arc-shaped groove support plate;

[0009] Fixed rotation unit: Installed on the dovetail-shaped slider;

[0010] Compression unit: Installed on the base plate.

[0011] The first motor drives the threaded rod to rotate. Under the action of the thread, the dovetail-shaped slider moves along the dovetail-shaped chute, so as to drive the device to move. The first electric telescopic rod on the mounting block drives the arc-shaped groove support plate to lift, so as to simply support the end of the steel pipe.

The output shaft of the second motor is fixedly connected with a gear. The gear is meshed with the gear ring. The second motor drives the gear to rotate. Through the meshing of the gear and the gear ring, the gear ring drives the rotating cylinder to rotate, so that the steel pipe can rotate in a small range, making the compression and extrusion of the steel pipe more uniform and flat.

[0013] Further, the fixed rotation unit further includes a fixed frame, a second electric telescopic rod, and an arc-shaped fixed clamp. The front and rear ends of the rotating cylinder are fixedly connected with fixed frames corresponding to the upper and lower positions.

When extruding the steel pipe, the hydraulic press squeezes the arc-shaped mounting plate, so that the device drives the replaceable extrusion template to apply pressure to the steel pipe, making the steel pipe flat. At the same time, part of the pressure is absorbed and cushioned by the spring to prevent the steel pipe and the equipment from being damaged. At the same time, the clamping connection between the clamping seat and the telescopic rod enables the replaceable extrusion template to be replaced at any time, thereby changing the outer surface size of the compressed steel pipe.

[0016] Further, it also includes a mounting seat and a replaceable cylinder. The rear side of the upper end of the bottom plate is fixedly connected to the mounting seat, and the upper side of the front end of the mounting seat is fixedly connected to a replaceable cylinder.
