Cutting ferrule pretension machine
(1) technical field
The utility model relates to a kind of minor-diameter steel-tube fastening means, particularly a kind of cutting ferrule pretension machine.
(2) background technology
In the minor-diameter steel-tube connection procedure, need specific purpose tools such as cutting ferrule and connecting leg nut, manually tighten with traditional way, but screwing force does not often reach requirement greatly, pipeline quality of connection and efficient are all very low, often cause disadvantages such as gas leakage or cutting ferrule come off.
(3) summary of the invention
The utility model provides a kind of design science, rational in infrastructure, easy to manufacture, easy to use at the deficiencies in the prior art, cutting ferrule pretension machine satisfactory for result.
A kind of cutting ferrule pretension machine, form by support, bearing, base, template, pretension mould, cylinder and joystick, support, bearing and joystick are fixed on the base, template is rack-mount, the pretension mould is installed on the bearing, and template is connected with the pretension mould, and support is provided with a spring steady pin that is used for fixing template, the pretension mould is communicated with by pipeline and cylinder, and cylinder is by steam transmitting pipe and joystick and source of the gas connection.
During use, the steel pipe that needs pretension is placed on the pattern hole place corresponding with this diameter of steel tube, connecting leg nut and cutting ferrule and pretension mould are aligned, the pulling joystick is connected gas circuit, the pretension mould drives the connecting leg nut and cutting ferrule clashes into template rapidly, thereby cutting ferrule is fastened on the steel pipe.
The utlity model has design science, characteristics rational in infrastructure, easy to manufacture, easy to use, satisfactory for result.
