Damaged deformation bronze ware correcting locating and repairing method

Abstract

The invention discloses a reparation device and a method thereof for the shape-righting and positioning of damaged and distorted bronze ware, belonging to the technical field of relic restoration, which is characterized in that an inner ring (4) is arranged in a damaged and distorted bronze ware (7); an inner adjusting bolt is connected with an inner gasket (6) on the inner wall of the damaged and distorted bronze through a plurality of screw holes on the inner ring (4); an outer ring (1) is arranged outside the damaged and distorted bronze ware (7); an outer adjusting bolt is connected with an outer gasket (3) on the outer wall of the damaged and distorted bronze through a plurality of screw holes on the outer ring (1); the screw holes on the outer ring (1) and the inner ring (4) are evenly distributed. The reparation device and method for the shape-righting and positioning of damaged and distorted bronze ware has an advantage that shape-righting and positioning of seriously damaged and distorted bronze ware are realized to ensure successful laser welding reparation.

Description

technical field [0001] The invention relates to a restoration technology of cultural relics, in particular to an orthopedic positioning repair device for damaged and deformed bronze ware and a method thereof. Background technique [0002] A large number of bronze cultural relics are unearthed every year in our country. During the long history, most of them have been damaged to varying degrees due to various reasons and need to be restored. "Chime bell" is a percussion instrument used in important activities such as court performances, sacrifices, court meetings or expeditions in ancient times, and it is also a treasure among Chinese bronze cultural relics. For example, the chime bell of Marquis Yi of Zeng unearthed in Sui County, Hubei Province in 1978 is not only a national treasure of China, but even known as "the eighth wonder of the world". The repair and restoration of the damaged and deformed bronze chimes is of great significance to historical research, scientific ex...

Problems solved by technology

However, there are two disadvantages: one is that most of the polymer adhesive materials need a certain amount of time to solidify, and it is more difficult to bond bronze cultural relics that need to be pried and shaped; the other is that most of the high-strength polymer adhesives are irreversible. Yes, it is difficult to make orthopedic treatment after solidification

However, laser welding has high requirements on the precision of the weld seam, and stress concentration will occur locally in the weld seam during the welding process, resulting in the misalignment of the weld seam or the change of the gap size, which will ultimately affect the welding effect

In addition, the shape of the chime bell itself is complex, and the shape of the damaged bronze fragments is also extremely irregular, which will directly lead to the extremely irregular shape of the weld seam. During the repair process, it is necessary to constantly change and adjust the welding position
