Description

Arch camber machine

Technical Field

The utility model relates to a profiled sheet makes technical field, specifically is an arch springing machine.

Background

The rainproof cover for the profiled steel sheet can be widely applied to power plants, cement plants, steel plants, chemical plants, coal plants, ports, docks, mine enterprises and the like.

Rain-proof cover of profiled sheet plays very big effect to goods, environment, can reduce the loss and the waste of goods when the goods in the transportation, makes the conveyer belt more safe and reliable in the transportation, secondly has also prolonged the life of cargo airplane.

The common rain cover that traditional wavelet pressure shaped steel board (crest and trough height difference is in 10mm) arch camber shaping formed can not satisfy high-end customer's user demand, and novel big wave (crest and trough height difference is in 18mm or above) rain cover then because of its characteristic that intensity is high, can process jumbo size singleness rain cover, possess non-deformable moreover, longe-lived characteristics, the rain cover of this type of material is used in the supporting of the large-scale bandwidth belt feeder abroad usually.

In China, the large-wave compression-type steel plate is processed and manufactured by fresh manufacturers in China due to the reasons of high strength, difficulty in processing, low qualification rate and the like. Especially, foreign orders require the rain cover to have the safe edge processing technology for preventing the edge from being cut. The technical communication of other manufacturers at other places is realized, the safe edge treatment process for preventing hands from being cut is a European standard process, and a domestic common rain cover does not have a similar process.

Moreover, the problem that the large-wave high-strength profiled steel sheet is difficult to arch is also long-standing, and particularly, the arch shape within the processing radius of 1000 of the large-wave profiled steel sheet is difficult to precedent in the same industry. The reason is that the height difference (more than or equal to 18mm) of the wave crest and the wave trough of the large-wave profiled steel sheet is much larger than that of the small-wave profiled steel sheet (usually less than or equal to 10mm), the stress moment during the arching processing of the large-wave profiled steel sheet is several times larger than that of the original small-wave profiled steel sheet under the condition of the same thickness and material, the stress point of the large-wave profiled steel sheet is deformed in advance due to overlarge stress, and the defects of folds, irregular bending and the like are generated, so that waste products are generated. The safety edge of the anti-cutting hand doubles the thickness of the edge of the steel plate, the stress yield strength is obviously increased compared with other positions, the deformation is also obviously different, and the processing difficulty is further increased.

When the same pushing feed amount is used in the operation of the three-roller arch springing machine, the stress is greatly increased, the profiled steel sheet is easy to form wrinkles due to overlarge stress, if the pushing feed amount is too small, the range of single arch springing degree interval is too small, and the arch springing amount (radian) required by arch springing cannot be processed.

The minimum camber of the small wave profiled steel sheet can reach R100mm radian on a typical three-roller arch raising machine, the camber of the large wave profiled steel sheet with the same steel thickness can not be less than R2000 radian in one-time camber raising of the typical three-roller arch raising machine under the same condition, the edge thickness of the safe edge profiled sheet for preventing hand cutting is doubled, and irregular profiling defects such as folds, waves and the like are generated during arch raising profiling.

Aiming at the difficulty of the arching processing technology, a cooking range must be additionally arranged, and a new processing technology and new processing equipment are innovatively researched and developed.
