There are materials and materials of the same size on the market. Governments of all countries_ In order to allow producers and users to comply with specific specifications, ^ is established industrial standards, applicability and safety of handle materials, to correct the island, reach consensus, improve quality, and promote industrial upgrading. Among the current industrial specifications, the CNS3934 specification of the Chinese National Standard (CNS) set by the Central Bureau of Standards, although formulated with the properties required for μ-class power screws', but the 149-class screw specifications do not meet the following requirements: It is difficult to meet the needs of the old materials and manufacturing methods, and the out of the clothes has led to the 14.9 level specification being gradually adopted and cancelled. The inventors are urged to research and develop the materials and manufacturing methods for the 14.9 grade strong screws 2 in the above-mentioned old specifications, and have applied for and have been approved by the Bureau of Public Affairs No. 553 786 "A kind of forged parts with tensile properties of μ ·% As shown in FIG.

Ίο 15 As shown in Figure 2, although the above manufacturing method can produce Forged parts with tensile properties of 14.99 grade high-mechanical f. However, in step (3) of the heat treatment process, after "heating and heat preservation", the structure of the forged parts will change from boron iron to vostian iron. During the "quenching" and "post-washing", the temperature of the ferritic iron structure will be reduced, and the hardened Asada iron and a small amount of residual Vostian iron will be passed. After more than _ times of "tempering" It can warm up and soften the loose iron in Asada, and the metamorphosis of the hot temperature becomes a feathery tissue, which decreases. The change is _ The non-reed = mixture of iron and ferrous iron has high strength and high strength. Finally, it is necessary to "quickly cool" and remove the residual Vostian iron to reduce the tempering brittleness. The above manufacturing method: can be produced The resistance is 14 () _ Ca 2 and the mechanical properties of the forging parts of the extension machine 2 are strong. Therefore, according to the above Γ__934 standard, it becomes a new standard specification. Tension: 2: i,?

However, although the above manufacturing method can produce forged parts 2 with tensile properties of 1499 high-strength mechanical properties, the following disadvantages have arisen in manufacturing: Rare father Jiagong Rishou · · In order to produce part 2 of toughened iron structure, on ίο 15 20 In step (3) of the heat treatment process described above, the counterfeit product must undergo several cooling and 'more than one-time tempering after heating, that is, it must go through various different processes during the process, and the processing temperature must also go through multiple times. It takes a long time and a short time to lift, the control is more complicated, and the manufacturing process consumes more time and energy. In addition, after the above-mentioned part 2 organization is subjected to beacon, it is easy to leave a small amount of Vostian iron. However, the beacon organization of this residual Wastfield iron is less stable at normal temperature, so it is necessary to remove the remaining Wastfield iron by quenching and cooling, and the processing is more complicated, so the process needs to be improved. Second, the quality is stable: The part 2 is mainly returned after quenching, so that the part 2 organization will be changed from Asada through iron spitting and scattered iron strange temperature metamorphosis becomes up__, but in the above-mentioned tissue metamorphosis, due to the use of high temperature Constant temperature metamorphosis, leading to a more unstable metamorphosis of Part 2, causing most of Part 2 to not complete the transformation. _ The organization is less. For a whole batch of Part 2 with a predetermined weight, the part with a large = 5/0 can achieve resistance. Tensile properties: Mechanical properties of high-strength knife with grade 4.99, making the product with low yield and relatively high cost. [Summary of the Invention] Therefore, an object of the present invention is to provide a method for manufacturing a forged part of grade 14.99 which has a short manufacturing time and 5 10 15 mechanical properties and stable tensile properties. A method for manufacturing a forged part of class 14.99 includes the following steps: (1) A alloy steel wire is subjected to a spheroidizing annealing-dipping line-rough drawing-softening annealing-> dipping line-fine drawing procedure.送 Send the wire that has passed through the ⑴ step to a forging part forming machine, punch and forge it, and then use a rubbing machine to knead to form a tooth pattern to become a part. (3) Heat treatment is performed at Haikou. The heat treatment process is: forging parts that are cold forged after rubbing teeth-front lacquer, ^ y J, light clean-heating and insulation (temperature 760 ~ 900 C 'Ri Mori 5 0 ~ 90 minutes, I need you 1 knife J temper tempering (temperature 300 ~ 40 (rc, time 30 ~ 60 minutes). / The effect of the present invention is in the heat treatment step, in After the temperature, the heat treatment by Voss tempering is directly used, so that the parts can achieve the tensile properties of 14.99 grades quickly and stably. Li _ With the high strength, it has better mechanical properties. , To meet the overall requirements of practical use 'so it has the effect of saving time and improving yield. [Embodiment], features and effects, in the detailed description, will clear the aforementioned and other technologies related to the present invention The content is described in detail below with reference to one of the preferred embodiments of the drawing. 20 200538215 As shown in FIG. 3, the preferred embodiment of the method for manufacturing a forged part with a tensile property of 14.99 according to the present invention is as follows: Perform: (1) choose an alloy steel Wire 3, such as SNCM439 nickel-chromium-molybdenum steel hardened wire, chemical composition contains C 0.36 ~ 0.43%, Si 0.15 ~ 0.35%, 5 μn 0.60 ~ 0.90%, Ni 1.60 ~ 2.00%, Cr 0 · 60 ~ 1.00% Mo 0 · 15 ~ 0.30% to meet CNS3935 material inspection requirements and meet the required hardening energy requirements. Of course, in material design, SCM445H (SAE4145H), SCM445, SCM440, SCM440H can also be selected. (2 ) The SNCM439 wire 3 is subjected to a two-step spheroidizing annealing and drawing process 10 to make the carbide particles round and smaller, increasing softness and ductility to facilitate punching and extrusion. The steps are: spheroidizing annealing ( Below abnormal temperature, about 680 ° C) —Dip line (pickling and scaly film) —Rough pumping (processing amount 20 ~ 30%) — Spheroidizing annealing (7 6 0 C) —Dip line (pickling and Salt-filling film) 4 fine extraction (within 5% processing volume). Of course, in annealing and wire drawing processing, depending on the material composition, thickness, and history of the wire 15 and other conditions, the program can be increased or decreased according to circumstances. The above-mentioned spheroidizing annealing treatment: due to the presence of citronite in ferrite and ferrous iron in a layered interaction, The initial analysis of the hypoeutectoid steel presents the skeletal carbon iron in the form of a network at the grain interface. This state has poor mechanical properties, and is easily deformed or cracked during quenching. Therefore, nodular annealing must be performed to make the steel interior Layered or reticulated spheroidal carbon iron spheroidizes the carbides into spheroidal crystals. The above-mentioned wire drawing treatment: drawing the wire to shrink its wire diameter, and when drawing, 'layered iron and snow The ferritic grain iron parallel to the clear carbon iron is slipped and deformed, and tiny cracks are formed along the splitting surface of the main body of the clear carbon iron, and the clear carbon iron 200538215 is cut to make it finer. (3) The wire 3 after the step (2) is sent to a forging part forming machine to form a semi-finished product with a pre-shaped shape, such as a screw, and the tooth pattern is rubbed on the surface of the semi-finished product by a dental rubbing machine to become一 fortified parts 4. (4) As shown in Figure 4, heat treatment is applied to the forged part 4. The heat treatment process is as follows: cold forged parts-before washing (first degreasing with hot water, then rinsing with cold water)-heating in the furnace Insulation (Temperature 76 ~ 90%, Time 50 ~ 90 minutes)-Voss Tempering (Temperature of 865 ~ ίο 15 20 ° C after heating and keeping in a salt bath with a temperature of 300 ~ 4〇 {rc The time is 30 ~ 60 minutes. The above-mentioned heating and heat-preservation treatment: gradually increasing 'decreasing or constant-temperature heat-preservation' in the furnace, for example, 860, 0, 88 (rc, 8800, 0, 88, 0, 88). It is gradually warmed in six stages such as 87 (TC and so on) to heat the parts tissue to the temperature of Vostyn iron stable, and maintain it until the metamorphosis is completely Vostchan iron. Tempering treatment: The parts 4 after heating and heat preservation are placed at a temperature of 300 to 40 ° C. The salt bath is cut cold, and the salt bath is maintained for m minutes to complete the transformation of the parts structure, and then cooled to room temperature. This implementation = Use the strange warming agent _) which is a neutral salt bath agent, and: Cold over = will make Vostian spinning into needles Changing iron under the state of organization: * 二 1 The above steps can produce parts with lower organization, 4, the rate of dislocation, removal, mechanical properties, reaching 9% ~ 14% under 140 kgf / W, And it becomes a strong screw with tensile properties and strong mechanical properties. From the above, it can be seen that the present invention has the following advantages over conventional ones: 9 200538215 that saves labor hours. The present invention is heating and heat preservation. After that, it was directly applied to Wo'jin: f, so that the service department 4 organization can be directly transformed into a lower-grade iron iron with better strength and toughness. The manufacturing process is simpler and the control is simpler. Moreover, it is not necessary to cool down and quench in the process. After heating up and tempering, it is not necessary to apply the rapid cooling treatment, so it can indeed save a lot of process steps and time. It can save energy. The quality is more stable. By the Voss tempering method, the parts 4 organization is directly transformed into Down change _, and the mechanical properties of down change iron, such as physical properties, elongation, elongation, tensile strength, etc., are better than conventional change iron, so part 4 can get better Strong and tough, and the coffee is abnormal, making the Ministry The tissue metamorphism of product 4 is relatively stable. Most of them can complete the tissue metamorphosis of toughened iron, that is, the amount of toughened iron obtained is large. For a whole batch of parts 4 with a predetermined weight, at least 8G% of parts 4 can Reaching the high-toughness mechanical properties of 14.99 grade tensile properties, the product of the present invention has a high quality yield rate, which can greatly reduce costs. In summary, the structure and characteristics of the present invention can indeed provide a forged part of 14.99 grade tensile properties. In accordance with the specifications of CNS3934, through the selection of materials and the degree of heat treatment, high-strength and high-toughness screws with a tensile characteristic of 14.99 can be produced, which makes the 14.99-class powerful screws produced by the present invention. Under the action of 140kgf / mm2, the elongation reaches 9% to 14%, which is not only faster in the manufacturing process, but also can fully save energy, and also makes the mechanical properties of the finished product more stable. Therefore, the present invention turns into a A manufacturing method capable of producing high-strength and high-toughness forged parts with high strength and toughness can achieve the purpose of the present invention. 10 200538215 No. 5 The above is only a preferred embodiment of the present invention. When it is not produced, the scope of implementation of the present invention is limited, that is, what is simple according to the scope of patents and the description of the invention The equivalent changes and modifications should still fall within the scope of the patent of the present invention.
