Embodiment Construction

[0012] like figure 1 As shown, this is a structural schematic diagram of the metal vacuum heating bag of the present invention. The upper plate 1 is a stainless steel plate with a thickness of 0.3mm, and there are stamped protrusions 6 on the stainless steel plate, which are formed by figure 2 It can be seen that this stamping protrusion is a circle around the central point A, the lower plate 2 is made of common 5mm thick steel plate, and the upper frame 4 and the lower frame 5 are made of 12mm thick common steel plate. Slots are arranged on the lower frame 5, and a silica gel pad 10 that plays a sealing role is placed in the slots. There are screw holes 12 on the frame, and fastening screws 3 are arranged in the screw holes. When the gas in the metal vacuum heating bag is drawn out from the air pump 11, under the action of atmospheric pressure, the upper plate 1 moves downward, and the surface of the upper plate 1 stretches out. , like a spring, the upper plate 1 can also...

Abstract

A metal vacuum heating bag is composed of an upper-layer panel, a lower-layer panel, an edge sealing device and an exhaust device and is characterized in that at least one of the upper-layer panel and the lower-layer panel is made of sheet metal with a corrugated section. The corrugated sheet metal is adopted to achieve the aim that the sheet metal can be restored every time after exhausting and compressing are carried out due to the fact that the corrugated sheet metal has a large elastic stretching rate in the sheet plane. In addition, the sheet metal has high air tightness, and therefore it is guaranteed that the metal vacuum heating bag can achieve a very high vacuum degree.

Description

Technical field: [0001] The invention belongs to the field of glass processing machinery, in particular to a metal vacuum heating bag. technical background: [0002] Silicone vacuum heating bags are used in the production process of laminated glass. Silicone vacuum heating bag, the silicone vacuum bag has a simple structure, durability, and low cost of use, and is widely used in the field of laminated glass manufacturing. Silica gel has low density, poor microscopic uniformity, and capillary pores, so the vacuum degree of silica gel vacuum heating bag is not high, generally around 0.03 atmospheres. This kind of vacuum can meet the requirements for general laminated glass production, but it is far from meeting the requirements for vacuum glass production. Invention content: [0003] The invention provides a metal vacuum heating bag. The vacuum bag has a simple structure, is easy to use, and has a higher degree of vacuum (up to about 5 Pa). [0004] The technical solution...
