Abstract
The invention discloses a heat treating method of a nickel-base alloy cylinder spiral torsion spring, comprising the following steps of forging two square billets; linearly cutting semicircular holes or threaded holes: polishing the surfaces of the square billets and linearly cutting a plurality of semicircular holes or threaded holes on the square billets; turning a bar stock: respectively turning both ends of the bar stock; linearly cutting the bar stock into two semicircular bar stocks: linearly cutting the bar stock into two semicircular bar stocks along the axial line; assembling for use: respectively inserting the two linearly cut semicircular bar stocks into the semicircular holes or the threaded holes on the square billets in the process of heat treatment and sleeving an inner hole of the torsion spring on each semicircular bar stock, wherein an angle formed by the inserted semicircular holes or threaded holes is a free angle of the torsion spring. The invention has low cost without independently making a heat treatment frock for some a torsion spring, is particularly suitable for small scale production and is flexibly applied.
Description
Technical field
The present invention relates to heat treatment method, particularly a kind of heat treatment method of nickel-base alloy cylindroid helicalcoil torsion spring.
Background technique
The heat treatment method of existing nickel-base alloy cylindroid helicalcoil torsion spring needs to make heat treatment frock, cost height for torsion spring separately.
Summary of the invention
The technical problem to be solved in the present invention is in order to overcome the defective of prior art, a kind of heat treatment method of nickel-base alloy cylindroid helicalcoil torsion spring to be provided, and it need not be separately that certain torsion spring is made the heat treatment frock, and cost is low.
The present invention solves above-mentioned technical problem by following technical proposals: a kind of heat treatment method of nickel-base alloy cylindroid helicalcoil torsion spring is characterized in that it may further comprise the steps:
Forge the square billet step: forge two square billets;
Line cutting semicircle orifice or tapped hole step: after the square billet surface finish, line cuts several semicircle orifices or tapped hole;
Turning bar step: turning is carried out at the two ends to a bar respectively;
Line cutting bar becomes two semicircle rod steps: a bar is cut into two semicircle rods along the shaft axis line;
Step is used in assembling: during heat treatment, the semicircle rod of two line cuttings inserts respectively in the semicircle orifice or tapped hole on the square billet, the semicircle orifice that inserts or tapped hole angle be the free angle of torsion spring, again with the torsion spring inner hole sleeve on the semicircle rod.
Proofread and correct free angle when preferably, the heat treatment method of described nickel-base alloy cylindroid helicalcoil torsion spring is applicable to the torsion spring heat treatment of different free angles, different angular length.
Preferably, after the heat treatment method of described nickel-base alloy cylindroid helicalcoil torsion spring is changed the semicircle rod diameter that inserts the torsion spring endoporus, be applicable to the torsion spring of different inner diameters.
Positive progressive effect of the present invention is: the present invention need not make the heat treatment frock for certain torsion spring separately, and cost is low; The present invention is particularly suitable for small lot batch manufacture, applying flexible.
Embodiment
Lift a preferred embodiment below and come the clearer the present invention that intactly illustrates.
The heat treatment method of nickel-base alloy cylindroid helicalcoil torsion spring of the present invention may further comprise the steps:
Forge the square billet step: forge two square billets, square billet is of a size of 110 * 90 * 50mm, and the material of square billet adopts InconelX-750 type refractory alloy;
Line cutting semicircle orifice or tapped hole step: after the square billet surface finish, along short transverse by drawing and appointed part, line cuts several semicircle orifices or tapped hole;
Turning bar step: selecting length is the InconelX-750 bar of 500mm, and turning is carried out at the two ends of a bar respectively, and an end turning is of a size of the screw thread of M1O * 65mm, and the other end turning is of a size of the screw thread of Φ 10 * 65mm; The intermediate portion external diameter is: torsion spring internal diameter-greatest limit deviation-0.5;
Line cutting bar becomes two semicircle rod steps: preferred dimension is the bar of Φ 12 * 500mm; Two ends are lathed and are of a size of Φ 1O * 65mm, cut into two semicircle rods along the shaft axis line then;
Step is used in assembling: during heat treatment, the semicircle rod of two lines cutting inserts respectively in the semicircle orifice or tapped hole on the square billet, the semicircle orifice that inserts or tapped hole angle be the free angle of torsion spring, again with the torsion spring inner hole sleeve on the semicircle rod, after adorning several by above method, two semicircle rods are inserted respectively in the semicircle orifice of another square billet correspondence and promptly finish.
Proofread and correct free angle when same frock of the present invention is applicable to the torsion spring heat treatment of different free angles, different angular length, only need to change insert the torsion spring endoporus semicircle rod diameter just applicable to the torsion spring of different inner diameters.
Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make numerous variations or modification to these mode of executions.Therefore, protection scope of the present invention is limited by appended claims.
