Abstract
The invention provides a straightening method for inner-tension deformed materials, which comprises the following steps: a mold is arranged on the working plate of a working platform of a straightener for inner-tension deformed materials; a steel wire is inserted into the work piece to be straightened; both ends of the steel wire are connected with a steel wire buckle on a hoisting cylinder; the work piece is positioned next to the mold and the position is adjusted; a variable frequency device is started in terms of straightening method for inner-tension deformed materials to rotate the motor for pretension; the motor is continuously rotated and more force is applied to a wire line; when the work piece is deformed to the extreme, the motor is gradually slowed down until the rotor is locked; then the potentiometer is counterclockwise rotated to stop the motor and the first straightening is completed; inspection is carried out before the straightening is finally completed. The straightening method for inner-tension deformed materials has the advantages that odd-formed cross section or extremely complicated odd-form cross section can be easily straightened so that the need is met to deal with different cross-sectional areas and different materials such as steels, stainless steel, alloy, aluminum alloy and other materials.
Description
Technical field
The present invention relates to metal material alignment field of mechanical technique, a kind of specifically internal tension deformation sectional material alignment method.
Background technology
The fairly simple way of present alignment is with after the metalwork heating, apply external force with machinery, alignment on mould, if take the straighten while cold method, need big machinery to apply the external force alignment, what the external force alignment was used is multiple roll straightener, stretch bending straightener or hydraulic straightening machine, and that these machineries all are volumes is big, it is big to take up room, cost an arm and a leg.
Summary of the invention
The objective of the invention is to design a kind of simple to operate, efficient is high, cost is low internal tension deformation sectional material alignment method.
Internal tension deformation sectional material alignment method of the present invention, be metamorphosis power, by applying stretching force to the steel wire rope that penetrates work piece die cavity inside in advance, this stretching force effectively puts on the whole length of work piece and on all sections simultaneously, its maximum distortion power then puts on work piece and mould contact site equably, under stretching force and mould synergy, make material continuously produce permanent deformation along its length, thereby reach the purpose of alignment processing.
Its method is as follows:
1, mould is contained on the working plate of workbench of straightening machine of inner-tension deformation section steel;
2, steel wire rope is penetrated in the workpiece of wanting alignment, steel wire rope two links to each other with steel wire rope buckle on the winding drum;
3, workpiece is close to mould, adjusts the position;
4, press the method for operating startup converter plant of straightening machine of inner-tension deformation section steel, motor is rotated, pre-stretch-draw;
5, motor is rotated further, and continues reinforcing on the steel wire rope, and when workpiece deformation was reached capacity, motor slowed down gradually, and until stall, be rotated counterclockwise potentiometer this moment quits work motor, and then alignment is for the first time finished;
6, check completion.
The advantage of internal tension deformation sectional material alignment method of the present invention is: special-shaped section or very complicated special-shaped section are carried out the alignment ratio be easier to, adapt to the needs of different cross-sectional, unlike material processing, as steel, stainless steel, copper alloy, aluminium alloy etc.
The specific embodiment
A kind of internal tension deformation sectional material alignment method, its method is as follows:
1, mould is contained on the working plate of workbench of straightening machine of inner-tension deformation section steel;
2, steel wire rope is penetrated in the workpiece of wanting alignment, steel wire rope two links to each other with steel wire rope buckle on the winding drum;
3, workpiece is close to mould, adjusts the position;
4, press the method for operating startup converter plant of straightening machine of inner-tension deformation section steel, motor is rotated, pre-stretch-draw;
5, motor is rotated further, and continues reinforcing on the steel wire rope, and when workpiece deformation was reached capacity, motor slowed down gradually, and until stall, be rotated counterclockwise potentiometer this moment quits work motor, and then alignment is for the first time finished;
6, check completion.
