Abstract
The invention discloses a kind of bending method making metal winding pipe, it is characterised in that include following procedure of processing: the drawing of grade metal bend pipe is cut out by (1) in the ratio of 1:1; (2) drawing after cutting out is placed with on work platforms; (3) being fixed on work platforms by one end of metal straight pipe blank, the fixing end of metal straight pipe blank overlaps with one end of metal winding pipe drawing on work platforms; (4) free end of metal straight pipe blank is applied external force, simultaneously with the bending section of concentrated acid acidified metal straight tube blank, acidifying direction is consistent with the bending direction of metal straight pipe blank, until the curved shape of metal straight pipe blank coincides with the drawing curved shape on work platforms, namely obtain metal winding pipe; (5) the remaining concentrated acid on bend pipe is cleaned with alkaline solution. The present invention does not need bending machine, only with manually just completing bend pipe process, it is possible to easily and efficiently a small amount of metal tube is curved.
Description
Technical field
The processing method that the present invention relates to metal tube, refers more particularly to the bending method making metal winding pipe.
Background technology
Field of machining needs various bend pipes, the particularly connecting portion of various parts, the bend pipe of high-volume and small lot utilizes bending machine to carry out bend pipe more at present, single-piece manufactures experimently employing loose tool, frost poured water by pipe and pipe fills husky method and carries out bend pipe, adopt bending machine and above method to carry out bend pipe not only equipment cost for single-piece production high, and it is long to design the bend pipe mould time cycle, tends not to meet manufacturing schedule and development progress.
Summary of the invention
The technical problem to be solved is to provide the bending method of a kind of metal tube, and the method need not utilize bending machine, it is possible to easily and efficiently a small amount of metal tube is curved.
For solving above-mentioned technical problem, technical scheme comprises the following steps: the drawing of grade metal bend pipe is cut out by (1) in the ratio of 1:1; (2) the metal winding pipe shape on the drawing after cutting out is placed with on work platforms; (3) being clamped on work platforms by one end of metal straight pipe blank, the other end of metal straight pipe blank is free end, and the fixing end of metal straight pipe blank overlaps with one end of metal winding pipe drawing on work platforms; (4) free end of metal straight pipe blank is applied external force, metal straight pipe blank is made to be gradually curved, simultaneously with the bending section of concentrated acid acidified metal straight tube blank, acidifying direction is consistent with the bending direction of metal straight pipe blank, until the curved shape of metal straight pipe blank coincides with the drawing curved shape on work platforms, namely obtain metal winding pipe; (5) with the alkaline solution of 1-3mol/L, the remaining concentrated acid on bend pipe is cleaned.
Preferably, concentrated acid is mass ratio is the concentrated sulphuric acid of 98%.
Preferably, acidification step is to carry out dripping concentrated acid along elbow curvature direction with experiment glue head dropper.
Preferably, alkaline solution is sodium hydroxide solution.
Preferably, sodium hydroxide solution is 2mol/L.
The invention has the beneficial effects as follows and do not need bending machine, only with manually just completing bend pipe process, it is possible to easily and efficiently a small amount of metal tube is curved.
Detailed description of the invention
Below in conjunction with detailed description of the invention, technical scheme is further described in detail.
