    彈簧淬火等方面的處理事項

    關于彈簧的一些處理方式,有些朋友也是不清楚的,小編整理了一篇有關的內容,希望能夠給您幫助,下面來看看彈簧淬火等方面的處理事項吧。
    Some friends don't know about some treatment methods of spring. Xiaobian has sorted out a relevant content and hopes to help you. Let's take a look at the treatment of spring quenching and other aspects.
    淬火
    quench
    彈簧淬火加熱時,應特別注意防止表面脫碳、過熱或過燒、晶界氧化等缺陷,必須在保持氣氛或可控氣氛的爐內加熱,或保養涂層應涂在彈簧上,然后暴露。根據鋼種用水或油加熱然后冷卻。
    When the spring is quenched and heated, special attention shall be paid to prevent surface decarburization, overheating or overburning, grain boundary oxidation and other defects. It must be heated in the furnace with maintained atmosphere or controllable atmosphere, or the maintenance coating shall be coated on the spring and then exposed. Heat with water or oil according to the steel grade and then cool.
    但是,為了減少彈簧的變形,防止開裂,提高強抗性,馬氏體分級淬火和貝氏體等溫淬火在生產中得到了廣泛的應用,也可以進行貝氏體等溫淬火。
    However, in order to reduce spring deformation, prevent cracking and improve strong resistance, martensite step quenching and bainite isothermal quenching have been widely used in production, and bainite isothermal quenching can also be carried out.
    強韌體轉變停止線,保留一部分奧氏體,然后繼續冷卻至室溫,使這部分奧氏體轉變為馬氏體,在組織上兼有下貝氏體和奧氏體,在性能上兼具強度和耐性,是一種強化增韌的方式。這些處理方法也需要進行回火處理,因為這種熱處理的冷卻能力有限,而且這些淬火工藝只能用于截面較小的彈簧。
    A part of austenite is retained at the stop line of strength and toughness transformation, and then cooled to room temperature to transform this part of austenite into martensite. It has both lower bainite and austenite in structure and strength and resistance in performance. It is a way of strengthening and toughening. These treatments also require tempering because the cooling capacity of this heat treatment is limited, and these quenching processes can only be used for springs with small cross-section.

    退火
    annealing
    各種圓鋼和硬鋼絲用于彈簧。為便于進一步冷拔或切削,必須進行軟化或球化退火,以降低材料的硬度,改善其切削性能或提高冷變形能力。彈簧材料應在保護氣氛的爐中加熱退火,以防止表面嚴重氧化或脫碳,退火組織應為球形珠光體,硬度約為180HB。
    Various round and hard steel wires are used for springs. In order to facilitate further cold drawing or cutting, softening or spheroidizing annealing must be carried out to reduce the hardness of the material, improve its cutting performance or improve its cold deformation ability. The spring material shall be heated and annealed in a protective atmosphere furnace to prevent serious oxidation or decarburization of the surface. The annealed structure shall be spherical pearlite with a hardness of about 180hb.
    規范化
    Standardization
    對于一些彈簧,如扭桿彈簧,在熱加工過程中很容易造成排列和性能不均勻,產生較大的內應力。采用正火可以達到使排列均勻細密,消除內應力,便于加工成型的目的。
    For some springs, such as torsion bar spring, it is easy to cause uneven arrangement and performance during hot processing, resulting in large internal stress. Normalizing can make the arrangement uniform and fine, eliminate internal stress and facilitate processing and molding.
    回火
    tempering
    彈簧淬火后應及時回火,以降低硬度和脆性,降低淬火內應力?;鼗鸺訜峋鶆?,回火脆性彈簧鋼簡單呈現?;鼗鸺訜岷?,應適當迅速冷卻。
    The spring shall be tempered in time after quenching to reduce hardness, brittleness and quenching internal stress. Tempering heating is uniform, and tempering brittle spring steel is simple. After tempering and heating, it shall be cooled appropriately and quickly.
    山東彈簧廠廠家提醒,彈簧材料為鋼和有色金屬,其中大部分為鋼,進給狀態包括棒材、線材、片材和帶材。有的在熱軋、冷軋、冷拔后進行退火、淬火和/或貝氏體等溫淬火,在熱處理前制成彈簧。
    Shandong spring factory manufacturers remind that the spring materials are steel and non-ferrous metals, most of which are steel. The feeding state includes bar, wire, sheet and strip. Some are annealed, Quenched and / or bainite isothermal quenched after hot rolling, cold rolling and cold drawing, and made into springs before heat treatment.
