The invention discloses an oven handle sleeve, which comprises a double-layer wall structure, including an outer wall and a bottom plate with an inner perimeter wall, connecting the upper and lower ends of the inner perimeter wall respectively, and a stainless steel plate forming the bottom plate, the inner perimeter wall and the outer perimeter wall; the thickness of the plate is 0.45-1.6 mm, the tensile strength is more than 450 MPa, and the elongation is more than 36. The contents of chromium, chromium and nickel are more than 20% and 9% respectively. The bottom plate, inner perimeter, through hole and outer perimeter are punched and drawn in turn. The plate is clamped tightly with the die. A gap is formed between the inner wall and the outer wall, and the lower end of the outer wall is lower than the bottom of the bottom plate. The selected stainless steel has the characteristics of good machinability, high toughness and corrosion resistance, and can be better used to make sleeves with good comprehensive properties. The sleeves are heat resistant, long term non oxidizing, non foaming and non molting, and have good heat insulation and heat dissipation effects.

一种烤炉手把套头及其制作工艺
本专利技术涉及一种用于手把端部的套头,尤其是涉及一种用于烤炉手把的套头。
技术介绍
手把的应用中,常常应用于门、窗或盖板等,手把通过套头安装在门窗或盖板上,保证手把安装牢固,该种结构也较为美观。烤炉的设置中,在门和/或盖板上同样需要安装手把,烤炉门或盖板上更需要通过套头来连接手把端部。烤炉的使用环境条件下,环境高温、有油盐,需要保证手把及套头安装牢固、有一定美观;更需要的是:套头能够耐热、隔热预散热、不腐蚀,不起泡、不脱皮。现有技术的烤炉手把套头,常见为铝材铸造件,套头为实体结构,保证套头强度,却常常出现起泡和/或蜕皮的现象。所以有必要设置一种烤炉手把套头,保证能够满足盐雾试验的测试,保证套头成品率。
技术实现思路
为克服现有技术的不足,本专利技术的目的在于提供一种烤炉手把套头及其制作工艺,套头不良率低,能够更好地应用于烤炉所在的高温盐雾环境。本专利技术为解决其技术问题采用的技术方案是:一种烤炉手把套头,包括所述套头为双层壁结构,包括有内层周壁、分别连接内层周壁上端及下端的外层周壁及底板,所述底板、内层周壁及外层周壁为不锈钢板一体成型;内层周壁与外层周壁之间设置有间隙;所述外层周壁的下端低于底板的下端。根据本专利技术的另一具体实施方式,进一步的有,所述套头为304不锈钢。一种烤炉手把套头的制作工艺,包括以下步骤:步骤a,底板成型,准备不锈钢板材,板材厚度0.45~1.6mm,抗拉强度≥450MPa,伸长率≥36%,铬含量≥20%,镍含量≥9%,冲床冲头向下冲拉板材中部,得到底板,内层周壁相对底板折弯预成型;步骤b,内层周壁成型,模 ...
