Description

Technical Field

[0001] The utility model relates to the field of steel pipe processing equipment, in particular to a rolling type steel pipe notching machine. Background Art

[0002] In order to achieve a quick connection between multiple steel pipes, it is often necessary to crimp the pipe fitting interface to one end of the steel pipe with a crimping machine in the project. Currently, most commonly used crimping machines use a plurality of arc-shaped clamp-shaped crimping heads arranged in a ring, which slide and squeeze toward the center of the steel pipe at the same time, so that the steel pipe is dented and the pipe fitting interface inserted into the mouth of the steel pipe is firmly crimped. Since multiple crimping heads are closely connected and slidably connected in the inner ring of a torus, and need to slide and squeeze toward the middle at the same time, if one of them is stuck or damaged, the crimping cannot be achieved. The crimping head needs to be disassembled and repaired or replaced, which is very inconvenient during disassembly and assembly, affecting the work efficiency; in addition, the radius of the arc-shaped clamp-shaped crimping head needs to be adapted to the outer diameter of the steel pipe to be crimped. If the crimping heads of different arc radii need to be replaced for the crimping of steel pipes of different diameters, the versatility is limited. In view of this, it is necessary to improve the existing crimping machine. How to improve the convenience of disassembly and assembly and the versatility of adapting to different pipe diameters to improve the work efficiency is a problem to be solved in this case.

The utility model integrates a group of pressure components provided with passive rollers and two groups of rolling components provided with active rollers on the frame, wherein one passive roller and two active rollers are evenly pressed and contacted at one end of the steel pipe to be pressed, and the two active rollers simultaneously drive the steel pipe to rotate and drive the passive roller to follow, so that the passive roller and the active roller simultaneously roll the steel pipe for pressing. The crimping machine can crimp by only rolling three rollers and the position of the active roller is adjustable. It has a simple structure and can meet the crimping requirements of steel pipes with different diameters, thereby improving the convenience of disassembly and assembly of the crimping machine and the versatility of adapting to different pipe diameters, thereby improving operating efficiency.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] The rolling assembly includes a driving roller and a second rotating shaft. The shape and size of the driving roller are the same as those of the passive roller. The second rotating shaft passes through a through hole set in the center of the driving roller and is fixedly connected to the driving roller. Both ends of the second rotating shaft are exposed.

[0009] The pressure assembly also includes a pressure frame and a pressure cylinder. The pressure frame is a semi-frame-shaped component formed by a horizontal top plate and two side ear plates, with its opening facing downward. Bearing seats are provided on the two side ear plates. The two ends of the first rotating shaft of the pressure assembly are respectively rotatably connected to the two side ear plates. The pressure cylinder consists of two pieces, and the lower ends of the two pressure cylinders are hinged on the horizontal top plate of the pressure frame.

This pressing machine only needs to use the rolling of three rollers to press the pipe, and the position of the active roller can be adjusted. First, its structure is simple, and it is very convenient to disassemble and install, and the failure rate is low; second, the outer diameters of the passive rollers and the active rollers do not need to be associated with the outer diameter of the steel pipe to be pressed.

Thereby, the convenience of disassembly and assembly of the pressing machine and the versatility of adapting to different pipe diameters can be improved, and the working efficiency can be improved. The utility model has reasonable design, simple structure, low cost and is easy to promote. BRIEF DESCRIPTION OF THE DRAWINGS
