Application of the hottest proe in mold manufactur

Application of pro/e in mold manufacturing of Yituo company

with the development of modern industry, multi variety and small batch production has become the mainstream of machinery manufacturing industry. With the rapid development of economy and society and the increasingly fierce market competition, enterprises are required to have a faster market response speed and provide higher quality products, which highlight the manufacturing of South Biao in the mold industry. The market requires faster and faster replacement of molds, more and more quantity, higher quality, and shorter delivery time

traditional mold manufacturing requires manual marking and turning, milling, planing and grinding of ordinary machine tools, which not only has a long manufacturing cycle, but also is difficult to ensure accuracy. Nowadays, a major aspect of product development is to develop new product shapes and structures, especially streamlined shapes composed of various free curves and surfaces. Traditional mold manufacturing can no longer meet the requirements. In order to meet the market demand, Yituo company introduced the mechanical cad/cam system pro/eng in 1996, that is, the deformation is proportional to the force ineer software, which has been successfully applied to the NC machining of casting dies and stamping dies, and achieved good economic benefits

pro/e software written with the concept of new Feature-Based Parametric modeling method, its modeling efficiency is significantly higher than other traditional modeling methods, and it is a representative product of three generations of cad/cam/cae software

secondly, PTC company can listen to users' suggestions and modify their software as soon as possible. For example, we found in pro/e17 that the cutting slope cannot be made from the circumference to the diameter direction. After it was proposed, the function of version 18 can be realized after modification. Secondly, PTC has friendly after-sales service, which really makes users feel at ease when buying and using

after using pro/e for more than a year, we feel that pro/e is very suitable for mold design and processing. First of all, the powerful 3D solid modeling of pro/e can construct all kinds of complex free-form surfaces. The entity model contains not only the geometric information of the shape of the object, but also the topological information between the parts of the object, so as to achieve the integrity and consistency of the information expressed by the object. The solid model has no ambiguity, and has the abilities of hiding, profile taking, color rendering, etc. the colored entity can translate, flip, zoom at will, just like playing with an object in the palm of your hand, it is easy to see all aspects of the object, which can better meet the requirements of cad/cam. Secondly, PTC can listen to users' suggestions and modify their software as soon as possible. For example, we found in pro/e17 that the cutting slope cannot be made from the circumference to the diameter direction. After it was proposed, the function of version 18 can be realized after modification. Secondly, PTC has friendly after-sales service, which really makes users feel at ease when buying and using. In the process of CAD modeling of cylinder head mold and NC machining of cylinder block mold, our company has received the enthusiastic guidance of engineers from PTC Beijing office

pro/e software makes our company quickly go to the market

it has been two years since our company introduced pro/e software in 1996. During this period, the friendly cooperation with PTC company has been deepened. At the same time, the application range of pro/e in the company is too high, and the customizable design is becoming more and more extensive. Initially, it was only applied in the design department. Now, from offices to professional manufacturers, from design to processing and manufacturing has been fully rolled out. The following is only a brief description of the application of pro/e in mold manufacturing

using the pro/scantools module of pro/e, the scanning data of the Western Hemisphere obtained from the NC machine tool is restored to the three-dimensional solid model of the main model

in order to be invincible in the market competition, our company improves the processing life of the company's overall stamping die. It is decided to carry out NC programming processing for the drawing die of the left rear column of agricultural vehicles. The complex surface shape of the automobile body covering parts has been recognized by everyone, because the imported product drawings are not clearly expressed. Therefore, we use the pro/scantools module of pro/e to restore the scanning data of the sample column obtained from the NC machine tool to the three-dimensional solid model of the main model. In the process of scanning and restoring, the number and location of the collected data points are rationalized. If the quantity is not enough, the surface will be distorted; Too much will affect the smoothness of the surface. The color of the paint of the 5 experimental machine should be beautiful and generous. The key cross-sectional dimensions and curve shapes provided by the product drawing of the main model are used to fit the solid model, so that the solid model can fully meet the requirements of the drawing. Then the three-dimensional solid models of punch, die and pressing frame are generated. The numerical control machining calculation of the mold is carried out in the processing environment of pro/mfg module. Through dynamic simulation, the whole process of tool cutting can be seen realistically, Observe whether the knife cuts parts, and add a safety plane to the place where overcut may occur

construct the cutting plane according to the given process parameters, analyze the overcut at one time, modify the position where the overcut occurs, generate the tool position file, and form the NC instruction in the format of FIDIA numerical control system after post-processing. The instruction is transmitted to FB2 and mt2v numerical control profiling through RS232, which can meet the experimental requirements of different levels of research institutes, universities, laboratories and enterprises, milling, and complete the numerical control processing of molds

processing conclusion

the production cycle is shortened

the NC programming time is 7 days, and the processing time of the mold is only 24 days, which is nearly 4 times shorter than the traditional processing method
