Research and application technique based on reverse engineering, mold repair

 With the development of modern industry, the mold increasingly prominent position in the manufacturing industry, is widely used in aviation, cars, ships and other industries. High quality, efficient, cost has been the pursuit of the eternal goal of manufacturing technology development, the mold as indispensable to modern industrial process equipment, improve product quality, increase production efficiency, saving energy and raw materials, reflecting the technical and economic aspects of the mold manufacturing products means, has become a key contemporary industrial production process development direction and involved in the production of competitive products. However, due to the natural wear and operating personnel to improper operation and other reasons, it is caused by wear of the mold or severely worn. Mold and imported, often because a certain part of the wear and scrapped, if re-manufacturing the mold is not only time consuming, but also additional manufacturing costs, and seriously affect the production. Therefore, mold repair work is particularly important.

  Traditional mold repair common measurement instruments detect, limit the amount of regulatory measurement, measurement of straightness error, flatness error measurement, roundness error of measurement and manufacturing special measuring tools and other wear areas conducted measurements, and then according to the mold wear to develop a rehabilitation program. Mold repair cost, low efficiency, repair precision is difficult to meet the requirements, far from being able to meet the needs of modern mold. And the structure is more complex mold helpless.Repair mold technology based on reverse engineering is a more advanced mold repair, and has good prospects for development in the field of mold repair.

1 Reverse Engineering

  "Reverse engineering" (Reverse Engineering RE), also known as reverse engineering, reverse engineering, namely the entity transformation CAD ​​models of digital technology, the general term of the geometric model reconstruction technique, model punch and die manufacturing technology. For items or samples, the use of digital measuring instrument measurement point cloud data, and then point cloud point cloud data preprocessing, model reconstruction, and then the use of CNC machine tools or rapid prototyping technology of its manufacturing, and ultimately finished the generation, reverse engineering process Reverse engineering, product design downstream to the design upstream information feedback loop. Reverse engineering usually include geometry Reverse to craft anti summation Reverse, widely used in the engineering field, geometry inverse.

  

  Reverse engineering technology is so widely used, mainly used in:

  ① the design of new products;

  ② imitation of existing products, copy, reproduce design intent;

  ③ damage or breakage reduction and repair;

  ④ product detection.

  Reverse engineering applications in the mold industry mold design and manufacture and mold repair, reverse engineering that only design prototypes and design drawings and design documents, the innovative design of the original mold structure and wear die wear parts repair.
