Problems solved by technology

[0007] The manufacturing process of the thermal insulation titanium cup disclosed above uses brazing material to weld and seal the vacuum hole at the bottom of the thermal insulation cup. Since the brazing material needs to be melted during the welding process, the shape of the brazing material after cooling and solidification is: Irregular shape, which makes it necessary to polish the cooled brazing material after welding and sealing with the brazing material, so that the bottom of the thermos cup is flat, and at the same time, it is difficult for the molten brazing material to ensure the complete sealing of the vacuum hole. Affect the yield of the thermos cup

Abstract

The invention relates to welding equipment for an air extraction hole in the bottom of a vacuum cup and a machining process of the welding equipment. The welding equipment comprises a machine frame base, wherein the machine frame base is provided with a top pressing device, a bottom lifting and rotating device and a guiding device which correspond to one another from top to bottom, and the top pressing device and the bottom lifting and rotating device are movably connected to the machine frame base; the top pressing device and the bottom lifting and rotating device move towards the guiding device; and the guiding device comprises a horizontally-arranged fixing plate, a conical surface arranged downwards is formed in the middle of the fixing plate, and a through hole is formed in the middleof the conical surface. Compared with the prior art, the welding equipment has the advantages that through the arrangement of the bottom lifting and rotating device and the guiding device, the to-be-welded position of the bottom of the vacuum cup is moved to the bottom of the conical surface of the guiding device, and the welding piece is moved to the to-be-welded position of the bottom of the vacuum cup under the action of gravity and the conical surface, so that the safety and the convenience of the welding process are ensured; and besides, the top pressing device is arranged to press the welding piece compactly, so that the welding stability of the welding piece and the vacuum cup is ensured.

Description

technical field [0001] The invention belongs to the technical field of thermos cup processing, in particular to a welding device and a processing technology for a vacuum hole at the bottom of a thermos cup. Background technique [0002] The stainless steel thermos cup is made of double-layer stainless steel inside and outside. The inner tank and the outer shell are combined by welding technology, and the air in the interlayer between the inner tank and the outer shell is extracted by vacuum technology to achieve the effect of vacuum insulation. [0003] The vacuum equipment used in the society for vacuuming vacuum flasks includes vacuum exhaust tables and vacuum brazing furnaces, and there are about two types and four types. One type is the desktop type with tail vacuum exhaust; the other type is the type of brazing furnace. The brazing furnace type is divided into: single chamber, multi-chamber, and multi-chamber with increased pumping speed. [0004] In the vacuuming pro...
