摘要:当地时间3月26日,德国汉诺威展览公司宣布,因新冠肺炎疫情不断加剧,2020年汉诺威工业博览会将不再举办。这也是汉诺威工博会创立73年来首次轮空。不过,主办方将在近期推出网上对接平台,供展商与专业观众建立联系、交流信息。
  当地时间3月26日,德国汉诺威展览公司宣布,因新冠肺炎疫情不断加剧,2020年汉诺威工业博览会将不再举办。这也是汉诺威工博会创立73年来首次轮空。不过,主办方将在近期推出网上对接平台,供展商与专业观众建立联系、交流信息。

此前,德国汉诺威展览公司于3月初宣布将原定于4月20日至24日举办的展会推迟至7月13日至17日。

据悉,汉诺威工博会是全球规模最大的工业盛会,从1947年首次举办至今已成为全球创新产品和自动化技术的主要展示平台,备受相关行业领军企业的青睐。按计划,下一届汉诺威工博会将于2021年4月举办。


因全球疫情升级,原计划于4月20-24日举办的全球最大工业展汉诺威工业博览会(HANNOVER MESSE)已推迟到7月中旬举行。这是一年一度的汉诺威工业博览会70余年历史上首次延期。


主办方德国汉诺威展览公司当地时间3月4日宣布,在与汉诺威卫生当局、汉诺威工业博览会参展商咨询委员会以及合作伙伴德国机械设备制造业联合会(VDMA)和德国电气电子行业协会(ZVEI)的共同协商下,决定将今年的汉诺威工业博览会推迟至7月13-17日举行。“决定在7月举办,是综合疫情发展以及参展商对新品发布时间要求的双重评估下作出的决定,有利于参展商向全球观众展示他们的创新成果并开展业务,”德国汉诺威展览公司董事会主席柯克勒(Jochen Köckler)表示,“鉴于上半年COVID-19冠状病毒引发的全球经济挑战,全新的展会时间更能为停滞的行业提供重启的机会。作为全球最重要的工业贸易展览会,汉诺威工业博览会将在7月为全球经济提供重要动力。”

1947年,正当德国仍试图从二战的失败中复苏经济时,英统区决定以举行一场贸易展览会的形式来刺激当时德国的经济。第一届“汉诺威工业博览会”以展出“德国制造”产品的目的亮相,在21天展期中获得巨大成功,汉诺威工业展逐渐发展为全球风向标式的国际技术和工业交流平台。2019年4月初举行的汉诺威展集结了来自75个国家的6500家展商,21.5万名专业观众中近40%来自境外——除德国观众之外,中国观众人数(7200)位居第二,荷兰(5900)第三,意大利(3400)第四,美国(3400)第五。

就在20多天前,汉诺威主办方曾在对疫情评估后宣布展览会将如期举行。在向中国参展商及观众的致信中,主办方表示,“根据世界卫生组织,罗伯特·科赫研究所和德国当局的评估,目前在德国感染这种新型冠状病毒的风险非常低。根据迄今为止的有效信息,目前在中国境外未造成严重的风险情况,因此我们不需要对展会采取限制性措施。德国汉诺威展览中心配备有最高标准的卫生,安全和医疗护理。”在10天前发布的声明中,这一计划仍未动摇,“我们在2月25日与参展商咨询委员会执委会及各协会商讨了当前形势。所有与会者都认为,现在决定推迟汉诺威工业博览会为时过早。展会将于4月20日开幕,我们并未收到参展商大量取消参展的通知。”

但随着欧洲多国拉响疫情警报、新冠肺炎确诊病例数继续攀升,商展行业遭到重击。根据德国疾病防控机构罗伯特·科赫研究所公布的数据,截至当地时间3月5日上午10时,德国共确诊349例新冠病毒肺炎感染病例,较3月4日10时,新增109例。另据当地时间3月4日18时意大利卫生部公布的最近数据,意大利现有新冠病毒患者2706例,死亡107例,治愈276例,累计确诊感染新冠病毒总人数为3089例,较3月3日18时新增587例,新增28例死亡病例。

疫情扩散之时,许多知名的欧洲展会已被迫取消或延期。2月13日,受疫情影响大型参展商陆续退展,33年从未中断过、原定于2月下旬举行的世界移动通讯大会(MWC)正式宣布取消。2月28日,世界规模最大的旅游业综合性展会之一的柏林国际旅游交易会也被临时取消。原定于3月举行、全球最大灯具与建筑电器展览会法兰克福照明展推迟至9月中下旬举行。

DIN 405 General Purpose Knuckle Screw Threads (Rd)

The Rd-series is a bit confusing because the Rd designation is used by both DIN 405, DIN 15403, and DIN 20400, but the screw threads are not identical in size or screw thread form. It appears that DIN 405 is the older standard, and was being used in underground mining operations but was the cause of mechanical failures in hoists (that could hurt). In 1951, to solve the mechanical failures, a new screw thread design:DIN 15402 and DIN 20400 was developed. Knowing this history, and if you are in the design process of a new Rd screw thread application, I would suggest that you lean toward the DIN 15403 and DIN 20400 screw thread if at all possible.

Quick summary of the differences between DIN 405, DIN 15403 and DIN 20400:
- DIN 15403 and
DIN 20400 have the same thread form/design.
-
DIN 405 uses metric nominal major diameter with threads-per-inch as the pitch designation. DIN 20400 thread uses metric nominal diameter with metric pitch. This is the easiest way to differentiate between the two standards.
-
DIN 405 has 63 designated screw thread sizes (8mm to 200mm) split between the favored Series 1 (40 sizes) and discouraged Series 2 (23 sizes). DIN 20400 has 47 designated screw thread sizes (10mm to 300mm).
-
DIN 405 has a limited range of pitch from 2.54mm (10-TPI) to 6.35mm (4-TPI). DIN 20400 increases the pitch as the nominal diameter increases using a range of pitch from 3mm to 16mm.
-
DIN 405 and DIN 20400 both employ a screw thread flank angle of 30°.
-
DIN 405 screw thread root and crest have a large full radius. DIN 20400 screw thread root has a large full radius, but the screw thread root has two smaller radii which leaves a flat at the bottom of the screw thread root.

Class-of-Fit
The tolerance paradigm for DIN 405 is somewhat complicated in that it gives class-of-fit several options for various diameters and is related to the length of engagement for the product threads. This structure allows for engineering flexibility; however; according to DIN 405-2 paragraph 4.1: … Where the tolerance class is not identified, it shall be taken to be 7H6H for internal threads and 7h6h for external threads. While the official standard allows for the DIN 405 Rd-series class-of-fit to be left off of engineering drawings; IMHO; it is a very simple task to include it in all references to the thread. By not reporting the class-of-fit on the drawing questions can arise which cost time and delay in manufacturing; which reduces profits. For the cost of the small amount of time and ink used to report the full thread requirements, many man-hours may be saved by an uncounted number of people over time.
