Molds and presses are two key factors in determining stamping quality, precision and productivity. Advanced presses can only be fully effective and achieve good results if they are equipped with advanced molds. The development direction of the mold is:
First, make full use of IT technology to develop mold design and manufacturing. The ever-increasing demands of users on press speed, accuracy, and mold change efficiency have promoted the development of molds. The body and engine are the two key components of the car.
It is not a large and medium-sized cover mold, its technology is intensive, reflecting the level of contemporary mold technology, and is an important part of the body manufacturing technology. Body mold design and manufacturing accounted for about two-thirds of the car development cycle, becoming the main constraint for car replacement. Currently
The replacement of the world's cars - about 48 months, and the United States only 30 months, this car will benefit from the application of CAD / CAE / CAM technology and three-dimensional solid steam cover mold in the mold industry Structural design software. In addition, the wide application of network technology provides
A reliable information carrier, real-time design and off-site manufacturing. At the same time, the application of IT technology such as virtual manufacturing will also promote the development of the mold industry.
Second, shorten the test time of metal forming molds. At present, the development of hydraulic high-speed test presses and tensile mechanical presses, especially on mechanical presses, can reduce the test time by 80% and has great potential for savings. This type of trial mechanical pressure
The development trend of the machine is to adopt a multi-link stretching press, which is equipped with a numerical control hydraulic stretching pad with parameter setting and state memory function.
Third, the progressive die in the body manufacturing has developed rapidly. The use of progressive punching or combination die machining of rotors, stator plates, or for the operation of connectors on automatic punch presses is a well-known stamping technique. In recent years, progressive combination die-cutting tools have been used in the body.
Production has begun to become more and more widely used, and the coil is directly processed into a molded part and a stretched part by a progressive die. The processed parts are also getting larger and larger, eliminating the need for cutting, oiling and slab transportation of the plates that must be connected in series with multi-station presses and complete sets of molds.
And other subsequent operations. Progressive combination dies have been commonly used in the automotive industry in the United States. They have the advantages of high productivity, low mold cost, no need for sheet shearing, and a 30% savings compared to stepped molds used on multi-station presses. But the application of progressive combination die technology
Restricted by the surface depth of the stretched edge, guided and transported strip material, it is mainly used for simple parts with shallow drawing depth, so it can not completely replace the multi-station press. Most parts should be considered for multiplex in eu Processing on a bit press.
The Unigraphics Progressive Die Design Process Wizard will focus on the compelling solutions of experienced Unigraphics users, which are automated through the Progressive Die Wizard, dramatically reducing lead time and increasing their productivity.
The student completed the PD pre-processing from the prepared Unigraphics sheet metal solid model; produced the blank layout; waste design and strip layout. The course introduces the application and customization of the die library. Each new skill is consolidated through full practice opportunities.
In addition, students receive a high level of observation of the functions under Unigraphics. The Unigraphics Progressive Die Design Process Wizard is the driving force for progressive die designers to a successful competitive position.
