Problems solved by technology

At present, most of the manufacturing methods of inner titanium outer stainless steel thermos cups on the market only use titanium liner, and the part where the user's mouth contacts when drinking water is mostly the middle layer. If the entire middle layer is made of titanium material, the manufacturing cost will be higher, so it is necessary to improve on this

Embodiment 1

[0051] A method for manufacturing an inner titanium outer stainless steel thermos cup, comprising the following steps:

[0052] S1: Take stainless steel raw material pipes and carry out water expansion on the stainless steel raw material pipes. Steps 1 are arranged on the stainless steel raw material pipes. The distance difference between the steps 1 is t1, and the t1 is 0.25 mm to form the middle layer of semi-finished products. A;

[0053] S2: Divide cups along the middle of the semi-finished middle layer A to form a semi-finished middle layer B, press ribs on the semi-finished middle layer B to form an inner card groove 2, the center of the inner card groove 2 and the top of the mouth of the semi-finished middle layer B The distance is t2, and the t2 is 2.5mm, and then punch out an exhaust groove 3 on the middle layer B of the semi-finished product. The width of the exhaust groove 3 is 1mm, the height is 2mm, and the depth is 0.3mm to form a stainless steel middle layer;

Abstract

The invention discloses a manufacturing method of an inner-titanium and outer-stainless-steel vacuum cup. The manufacturing method comprises the following steps: S1, water swelling is conducted, and a semi-finished product middle layer A is formed; s2, cup separation is conducted, a semi-finished product middle layer B is formed, an inner clamping groove is formed through ribbing, and a stainless steel middle layer is formed; s3, opening matching is carried out, and an assembly A is formed; s4, a titanium opening ring is sleeved through a step guide sleeve to form an assembly body B; s5, opening matching is conducted, and a semi-finished vacuum cup A is formed; s6, a stainless steel middle-layer bottom sheet is assembled to form a semi-finished vacuum cup B; s7, a stainless steel shell bottom sheet is assembled, vacuumizing is conducted, and a semi-finished vacuum cup C is formed; and S8, a silica gel sleeve is tightly sleeved, a plastic part is tightly matched, a silica gel pad is tightly attached, and manufacturing of the inner-titanium and outer-stainless-steel vacuum cup is completed. By arranging the titanium opening ring and optimizing the manufacturing method, the mouth contact part of the vacuum cup is made of a titanium material, the manufacturing method is simple, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of thermos cups, in particular to a method for manufacturing a stainless steel thermos cup with titanium inside and outside. Background technique [0002] The thermos cup is generally a water container with a vacuum insulation layer, with a cover on the top and a tight seal. The vacuum insulation layer delays the heat dissipation of the liquid contained inside, so as to achieve the purpose of heat preservation. At present, most of the manufacturing methods of inner titanium and outer stainless steel thermos cups on the market only use titanium liner, and when the user drinks water, most of the mouth contact parts are the middle layer. If the entire middle layer is made of titanium material, the manufacturing cost will be higher, so it is necessary to Improve this. Contents of the invention [0003] The invention provides a new manufacturing method of a stainless steel thermos cup with a titanium inside an...
