Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a kind of repair device of crucible deformation applied to coating engineering, belong to industrial lens production technical field. BACKGROUND
[0002] High-precision industrial lenses are widely used in electronic information, aerospace, automobile manufacturing and security technology, and have a positive effect on promoting the development of manufacturing industry. However, they also face challenges such as the growth of contact lens use, advanced vision correction technology, low industry concentration, high markup in the middle, and so on. In addition, as labor costs continue to rise, the operating costs of lens production enterprises also increase, which poses a challenge to the profitability of the enterprise. Therefore, in the production process of high-precision industrial lenses, under the premise of ensuring quality, cost reduction and revenue increase have become another arduous task for the lens manufacturing industry.
[0003] Currently, the cost of coated crucible is relatively high, and the crucible deforms severely during long-term use. The original lathe repair method has many shortcomings: ① low efficiency, the lathe milling repair method for deformed crucible is low in efficiency and high in labor cost; ② low reusability, the lathe milling repair method for deformed crucible is to process the deformed part of the crucible into the original shape, so the repaired crucible is thinner and can only be repaired once. After deformation again, it cannot be repaired again. SUMMARY
[0004] The utility model solves the technical problems existing in the prior art and provides a repair device for deformed crucible applied to coating engineering.
[0005] The technical problems of the prior art are solved by the following technical scheme: a repair device for deformed crucible applied to coating engineering, the lower mold cavity has a lower mold hole, the lower part of the spring cover plate is connected with a spring, the other end of the spring cover plate has a center screw hole, the center screw hole is connected with the lower mold hole, and the lower mold and the spring cover plate can be connected by bolts, the lower part of the upper mold matches the lower mold cavity, the crucible is connected between the upper mold and the lower mold, and one end of the spring is connected with the middle part of the spring cover plate.
[0006] The utility model has the advantages of solving the defects of low efficiency and low reusability of the original lathe milling repair, using mold or model method for deformed crucible repair, the same crucible can be repaired multiple times, which maximally improves the reusability of the crucible, is easy to operate, saves repair time, is simple and practical, is suitable for on-site operation, solves the previous repair difficulty and low reusability, ensures product quality, and effectively reduces production cost.
[0007] Because the crucible repair is the shape repair, the lower mold fixture needs to be matched with the crucible more tightly, because the matching gap is too small, after the upper mold fixture is pressed in, the crucible is easily stuck in the lower mold fixture and is difficult to take out, the utility model structure adds the spring, when the upper mold fixture is pressed in and lifted, the spring pops up the crucible upward, which facilitates taking out. Because the crucible material is copper, the contact surface is unevenly stressed in the pressing process, and the contact surface has a deformation risk, therefore, the utility model adds the structure of the spring cover to solve the difficulty.
