Description
技术领域technical field
本发明涉及不锈钢保温杯制备技术领域，具体为一种不锈钢保温杯的局部水涨制备工艺。The invention relates to the technical field of preparation of stainless steel thermos cups, in particular to a process for preparing local water swelling of stainless steel thermos cups.
背景技术Background technique
保温杯一般是具有真空隔热层的盛水容器，顶部有盖，密封严实，通过真空隔热层使装在内部的液体延缓散热，从而达到保温目的。The thermos cup is generally a water container with a vacuum insulation layer. The top has a cover and is tightly sealed. The vacuum insulation layer delays the heat dissipation of the liquid inside, so as to achieve the purpose of heat preservation.
对于不锈钢保温杯的制备过程中，其内胆主要采用拉伸工艺（拉管工艺）进行制备。拉伸制备的内胆就是用一个厚的不锈钢片反复冲压，通过模具的塑性，逐渐成型不锈钢管材的方式。通过拉伸工艺成型的不锈钢水杯管坯无缝，内壁整洁。拉伸工艺不能一次性拉伸到位，尤其是水杯直径上下不同的情况下，会有明显的拉伸痕迹，这个是无法避免的，但是可以通过抛光等工艺消除。拉伸工艺对水杯壁厚有明确的要求，壁厚不能过薄，否则会出现变形破损等问题。For the preparation process of the stainless steel thermos cup, the inner liner is mainly prepared by the drawing process (tube drawing process). The inner tank prepared by stretching is a method of repeatedly punching a thick stainless steel sheet, and gradually forming a stainless steel pipe through the plasticity of the mold. The stainless steel water cup tube blank formed by the stretching process is seamless and the inner wall is clean. The stretching process cannot be stretched in place at one time, especially when the diameter of the water cup is different from top to bottom, there will be obvious stretch marks. This is unavoidable, but it can be eliminated by polishing and other processes. The stretching process has clear requirements for the wall thickness of the water cup, and the wall thickness cannot be too thin, otherwise problems such as deformation and damage will occur.
目前针对不锈钢水杯的拉伸工艺存在着拉伸困难、拉伸操作要求较高、成本较高的问题。特别是针对上下异形的不锈钢水杯，拉伸工艺显然不能制备得到需要的不锈钢水杯内胆。At present, the stretching process for stainless steel water cups has the problems of difficulty in stretching, higher requirements for stretching operations and higher costs. Especially for stainless steel water cups with special shapes up and down, the stretching process obviously cannot prepare the required stainless steel water cup liner.
因此，针对目前的不锈钢水杯的制备工艺，提供一种新的制备工艺。Therefore, a new preparation process is provided for the current preparation process of the stainless steel water cup.
发明内容SUMMARY OF THE INVENTION
