Polyurethane tube deformation numerical control shaping and rounding device

Abstract

The invention relates to a polyurethane tube deformation numerical control shaping and rounding device which comprises a machine frame, a rounding plate and rounding jack assemblies. The rounding plate is fixedly installed on the machine frame. The rounding jack assemblies are evenly installed on the periphery of the rounding plate at intervals. Each rounding jack assembly comprises a base, a servo motor, a worm and gear driving mechanism, a lead screw and a claw hook, wherein the base is fixedly installed on the periphery of the rounding plate and provided with the worm and gear driving mechanism, a worm is driven by the servo motor, the exterior of a worm gear is in meshing transmission with the worm, and the interior of the worm gear is in meshing transmission with the lead screw. The lead screws of all the rounding jack assemblies extend to the center of the rounding plate, and the ends, facing the center of the rounding plate, of the lead screws are fixedly provided with the clawhooks. The polyurethane tube deformation numerical control shaping and rounding device performs rounding automatically, can allow a steel pipe to be quite conveniently inserted therein and greatly saves the pipe inserting time; and due to one-time rounding, the whole pipe can be inserted in, and work efficiency is effectively improved.

Description

technical field [0001] The invention relates to a polyurethane tube shaping device, in particular to a polyurethane tube deformation numerically controlled shaping and returning device. Background technique [0002] Polyurethane insulation pipes are roughly divided into four types: prefabricated direct-buried high-density polyethylene polyurethane insulation pipes, which are composed of working steel pipes, polyurethane insulation layers, and high-density polyethylene jacket pipes, and are mainly used for heating; direct-buried steel-sheathed steel steam insulation pipes Pipe, composed of working steel pipe, inorganic insulation material (glass wool, aluminum silicate, calcium silicate, rock wool, etc.) Composed of glass fiber reinforced plastic outer protection, often used for overhead; spiral iron insulation pipe, including working steel pipe, insulation material and spiral iron outer protection layer, double-layer insulation material can be used when the conveying medium ...

AI Technical Summary

Problems solved by technology

[0003] The polyurethane outer sleeve of the outer ring of the polyurethane insulation pipe has a large diameter and poor strength, especially if it is placed for a long time, it will cause great deformation, and the larger the diameter, the larger the deformation and the greater the stress. It is estimated that it is about 800 kg , has brought a lot of trouble to the steel pipe sleeve, time-consuming and labor-intensive
