Abstract
The utility model discloses a device for rounding and expanding pipes, and particularly relates to an expanding rounder. The expanding rounder comprises a rounding die which is vertically installed on a working platform through a die seat. An expansion core is arranged inside the rounding die, a hydraulic cylinder which can drive the expansion core to expand is arranged below the working platform, a limiting resistance ruler which can detect lifting displacement of the hydraulic cylinder is arranged on one side of the hydraulic cylinder, the limiting resistance ruler is connected to a computer through a control system, and the computer displays machining parameters. By the adoption of the structure, due to the fact that the limiting resistance ruler is arranged on one side of the hydraulic cylinder and the limiting resistance ruler is connected to the computer through the control system, the limiting resistance ruler can detect the lifting displacement of the hydraulic cylinder and transmit the lifting displacement to the control system, then the computer displays the machining parameters, and therefore accurate control over in-place machining of the pipes through the control system is achieved.
Description
Technical field
The utility model relates to the equipment that the hole enlargement of a kind of tubing full circle is used, specifically a kind of hole enlargement rounding machine.
Background technology
In the production process of steel pipe, usually need through the hole enlargement full circle operation to steel pipe, to guarantee the geometry circularity of the steel pipe of being produced.Existing hole enlargement full circle equipment in use tends to the inaccurate situation of processing yardstick occur because the operation of control system is not in place, makes thus the product that processes defective, causes the quality of product can not be guaranteed.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of can reliable, accurate controlled working precision, guarantee the hole enlargement rounding machine of product quality.
In order to solve the problems of the technologies described above, hole enlargement rounding machine of the present utility model, comprise by die holder and vertically be installed in rounding die on the workbench, be provided with the core that rises in the rounding die, the below of workbench is provided with the hydraulic cylinder that can drive the core spreading that rises, one side of hydraulic cylinder is provided with the spacing resistance scale that can detect hydraulic cylinder lifting displacement, and spacing resistance scale connects on computers by control system and can pass through the Computer display machined parameters.
After adopting above-mentioned structure, because a side of hydraulic cylinder is provided with spacing resistance scale, spacing resistance scale connects on computers by control system, can detect the displacement of hydraulic cylinder lifting and pass to control system by spacing resistance scale thus, then by the Computer display machined parameters, realized thus by control system the processing of pipe fitting being put in place and accurately controlled.
