Abstract
The invention belongs to the field of medical apparatuses and instruments, and particularly relates to a manufacturing technique of a medical fastening screw. The manufacturing technique of the medical fastening screw comprises the following steps: coping a steel wire; coating the steel wire; drying the steel wire; drawing the steel wire roughly; annealing; winding up, testing and coating lubricant; drying by baking or drying in the air after coating lubricant; and finish drawing. The manufacturing technique of the medical fastening screw has the advantages that the technique is simple, toughness of the medical fastening screw manufactured through the method is good, and medical effect is good.
Description
Technical field
The invention belongs to area of medical devices, specifically a kind of production technology of medical trip bolt.
Background technology
Stainless steel composition roughly is that iron and chromium also have the essences such as carbon to combine.The household wares stainless steel can be divided into greatly 430,304 (18-8), 18-10 Three Estate.430 stainless steels: the chromium that iron+12% is above, can prevent the oxidation that natural cause causes, be referred to as stainless steel, be No. 430 at the code name of jis, therefore be called again 430 stainless steels.But 430 stainless steels can't be resisted the oxidation that airborne chemical substance causes, and after 430 stainless steels seldom use a period of time, still the situation of oxidation (getting rusty) can be arranged because of non-natural cause; The 18-8 stainless steel: iron+18% chromium+8% nickel, can resist the oxidation of chemistry, this stainless steel is No. 304 in the jis code name, therefore is called again 304 stainless steels; The 18-10 stainless steel: but airborne chemical composition is more and more many, and some pollutes more serious place 304 all can have the situation of getting rusty; So the senior articles for use that have are used 10% nickel and made, so that it is more durable more against corrosion, this stainless steel is called the 18-10 stainless steel.The saying that similar " adopting the most advanced medical stainless steel material of 18-10 " arranged in the tableware explanation that has.These three kinds of stainless steels, the most simply resolution mode is: inhale the bottom with magnet, inhale to such an extent that what live is 430, inhale incessantly be 304 and 18-10.But pot edge or the front and back end of soupspoon of 304 bowls are inhaled to such an extent that live sometimes, are because the magnetic that polishing produces.So the most accurate mode is to inhale the bottom.But above stainless steel can't be applied to medical treatment, more can not make Medical screw.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of production technology of the medical trip bolt for medical field.
The invention provides following technical scheme:
The production technology of medical trip bolt, it comprises the steps:
The reconditioning of a, steel wire is carried out reconditioning to the defective of raw material steel wire, embroidery, crack and burr;
B, tunicle, the steel wire after reconditioning adopt fruit glaze agent to carry out tunicle, and the temperature of tunicle is 90 ℃-95 ℃, and the time is 12-18min;
C, oven dry, the steel wire after tunicle is good is dried at the baking oven of 100-110 ℃;
D, rough carries out drawing for the first time in straight drawing machine, dry online before drawing, and temperature is 130 ℃;
E, annealing, the steel wire after rough is annealed at the temperature of 700 ℃-780 ℃, on-line cooling after annealing, logical protective gas when cooling;
Then f, take-up check applies lubricant, dries or dry after applying lubricant;
G, finish draw, dry or dry after drawing again;
H, the steel wire after finish draw is carried out cold-heading by cold headers become T-shaped workpiece;
I, with the afterbody stub end turning of T-shaped workpiece;
J, then at T-shaped workpiece afterbody stub end by the measuring truck perforating;
K, hold the side face screw thread of getting on the bus to form finished product the anterior microcephaly of T-shaped workpiece.
Described protective gas is inert gas.
Advantage of the present invention is that technique is simple, and Medical screw toughness is high, and medical effect is good.
The specific embodiment
The production technology of medical trip bolt, it comprises the steps:
The reconditioning of a, steel wire is carried out reconditioning to the defective of raw material steel wire, embroidery, crack and burr;
B, tunicle, the steel wire after reconditioning adopt fruit glaze agent to carry out tunicle, and the temperature of tunicle is 90 ℃-95 ℃, and the time is 12-18min; Be generally 90 ℃ or 93 ℃ or 95 ℃, time is 12 or 15 or 18min, the effect of fruit glaze agent is to make steel wire crude, can fully contact with the wire drawing powder during drawing, adsorb the wire drawing powder by fruit glaze agent, the effect of lubricating when fruit glaze agent has drawing in addition simultaneously, fruit glaze agent are wire drawing industry material commonly used, and be known in industry;
C, oven dry, because fruit glaze agent is moist, so the steel wire of tunicle after good dry at the baking oven of 100-110 ℃, general bake out temperature is 100 ℃, also 105 ℃ or 110 ℃, oven dry is for the fruit glaze agent that hardens, can better take away the wire drawing powder;
D, rough carries out drawing for the first time in straight drawing machine, dry online before drawing, and temperature is 130 ℃;
E, annealing, the steel wire after rough is annealed at the temperature of 700 ℃-780 ℃, on-line cooling after annealing, logical protective gas when cooling, on-line cooling is to allow steel wire pass through a pipeline, has the chuck with cooling water in duct wall, protective gas passes in this pipe simultaneously;
Then f, take-up check applies lubricant, dries or dry after applying lubricant, and lubricant is generally lime or oil or soap;
G, finish draw, dry or dry after drawing again;
H, the steel wire after finish draw is carried out cold-heading by cold headers become T-shaped workpiece;
I, with the afterbody stub end turning of T-shaped workpiece;
J, then at T-shaped workpiece afterbody stub end by the measuring truck perforating;
K, hold the side face screw thread of getting on the bus to form finished product the anterior microcephaly of T-shaped workpiece.
Described protective gas is inert gas.
