中央空调温度控制器转盘冲压模设计

摘  要

中国空调业的发展历经坎坷，从奢侈消费品飞入寻常百姓家，在实现了自身的巨大飞越之时，也见证了社会经济生活的巨大变迁。透过空调业二十多年来的发展，我们在亲身感受着历史的车轮由缓缓行驶步入飞速发展的大提速。

1978年，社会大众对于空调的概念还局限于一部分特殊场合的重要物品。而进入1997年之后，随着空调市场化运作的深入、人们生活水平的大幅提升，一大批在改革开放的春风中先富裕起来的人群，开始将空调作为日常的家居用品使用。随后，全国各大中城市的空调普及率大幅提升，而在长三角、珠三角等经济发达地区，许多乡镇居民的空调消费量也在呈现逐年增长的势头。  

随后，国内居民家庭中的空调普及率稳步提升，2003年全国30个城市居民家庭中空调的保有率达到了55.9%，和1998年相比，增长了15个百分点。上海、北京、广州等超大规模城市居民的空调每百户拥有率已经达108%以上。

随着空调业的发展中央空调控制器转盘等这类空调的配套精密零件的制造成为我国现代空调业的一个重要组成部分。这些零件大部分需要用通过精密的模具来制造。

由于种种历史原因，我国模具工业与当前工业发展还不很适应。无论是在设计制造技术和生产能力方面，还是在管理水平方面，模具工业均远远不能满足需求，它严重影响工业产品的品种、质量和生产周期，削弱了其在国际市场上的竞争能力。近年来，我国模具进口幅度呈大幅下降之势，并有超亿元出口额。大型、复杂、精密、高效和长寿命模具也逐年上新的台阶，体现高水平制造技术的级进模也越来越多，冲压自动线、自动冲技术也得到广泛应用。我国模具行业的技术迅速提高，模具国产化已经取得十分可喜的成绩，这将对我国在国际市场的竞争能力和综合国力的提高起到有力的促进作用。

ABSTRACT

The industry of Chinese Air Condition has been suffering a long time. It used to be a luxury machine and no one used it, but now it can be seen in almost every families. The developments of this industry not only raise its own value, but also witness the huge changes of the economy in our modern society. Though this development, we are just like putting our selves into the wheels which are continuously driving us to the success.    In 1978, the requirements to the air condition are just at a extremely low level. When it comes 1997, people's living standard increases dramatically. Lots of people are becoming richer than ever before. They can easily afford to all kinds of modern home appliance. The air condition which is one of the most famous one are being more and more used in normal lives. The reports said that in down areas, the percentage of people who have air condition is increasing sharply those years. Also in other sub urban areas, the consume on this machine also rises steadily every year.    During the following years, this development didn't stop. The statistics reveals that in 2003, the percentage of people who has been holding an air condition in 30 cities of all country has rated at 55.9%, which is 15 percent higher than that of 1998. In big cities like Shanghai 、Beijing and Guangzhou, this percentage even picked at more than 108%.    Also these developments of air condition make the manufacturing its parts such as Central air conditioning temperature controller turntable becoming an essential part to constitute our modern industry of air condition. These parts are mostly made by precise moulds.

Because of various history reason, molding industry of china and the industry develop now are still not adapt very much. Is in the aspects of designing to make the technique and produce the ability regardless, still manage the level aspect, the molding tool industry can't meet the demands all and far and far, the species, quantity and the production periods of its serious influence  industry product, weakened its competition ability in international market. In recent years, our country the molding tool imports the range to present to descend significantly, and have over hundred million dollar’s exit sum. Large, complications, nicety, the longevity life, also ascend the new step year by year with molding tool efficiently. More and more high manufacturing technique level’s progressive die has appeared. Hurtle to press the automatic line and hurtle the technique to also get the extensive application automatically. The technique of the molding tool profession of our country has developed very fast, the molding tool national product turn to have already very pleased result, it will let our country in the international market of exaltation of competition ability and comprehensive national strength rise to promote the function.
