A lock armoring machine and its guide belt reversing forming device

Abstract

The invention discloses a bar guiding reversing and forming device. By the adoption of the bar guiding reversing and forming device, a special-shaped steel bar can be converted into the state that the steel bar is erected perpendicularly relative to the horizontal plane and advances along the vertical plane from the state that the steel bar is parallel to the horizontal plane and advances along the horizontal plane, the whole process is quite simple, the special-shaped steel bar is erected gradually through the gradual reduction of the width of peripheral grooves and will not be damaged, conversion is quite rapid, and therefore rapid damage-free state conversion of the spherical-shaped steel bar is achieved; besides, steering wheels are adopted, all the steering wheels rotate continuously, so that continuous conveyance is achieved, and therefore the work efficiency is improved. Then, the special-shaped steel bar enters a first forming gap and a second forming gap, the special-shaped steel bar can be formed and is in a circular ring shape after leaving out of the first forming gap and the second forming gap, the special-shaped steel bar extends frontwards and backwards in a screw mode, continuous forming can be achieved through continuous rotation of all the wheels, and therefore work efficiency is improved. The invention further discloses a buckle armoring machine comprising the bar guiding reversing and forming device.

Description

technical field [0001] The invention relates to the technical field of guide belt reversing forming, in particular to a lock armoring machine and a guide belt reversing forming device. Background technique [0002] At present, the application of oil pipeline hoses is becoming more and more widespread, especially onshore oil exploitation is becoming increasingly scarce, and the proportion of subsea oil exploitation will increase, which will inevitably increase the demand for marine hoses. [0003] Due to the particularity of the use environment, the marine hose needs to have high pressure resistance. Now the marine hose is generally armored, and a pressure-bearing layer is added to the outside of the marine hose. [0004] When making the pressure-bearing layer, special-shaped steel bars need to be introduced into the armoring machine. The special-shaped steel bars include S-shaped steel bars and Z-shaped steel bars. The special-shaped steel bars themselves are placed in rolls...

AI Technical Summary

Problems solved by technology

[0004] When making the pressure-bearing layer, special-shaped steel bars need to be introduced into the armoring machine. The special-shaped steel bars include S-shaped steel bars and Z-shaped steel bars. The special-shaped steel bars themselves are placed in rolls. The special-shaped steel strips are continuously wound on the marine hose. In this process, the special-shaped steel strips need to change their state, and the special-shaped steel strips need to be reversed, from the state of being parallel to the horizontal plane and advancing along the horizontal plane to being erected vertically relative to the horizontal plane. And in the state of advancing along the vertical plane, this conversion is very complicated, and it is very easy to cause loss to the special-shaped steel bar itself

[0005] At the same time, for the protective sheath formed after the special-shaped steel strip is armored, the forming efficiency of the special-shaped steel strip itself is low, and the assembly efficiency is low when it is applied to the armor on the marine hose. The existing pressure-bearing layer of the marine hose Using steel strips and flat steel wires, the pressure bearing capacity is low after production, so it can only be used in shallow sea areas, but not in deep sea areas.
