You must figure out the Disposable medical device mould of the tongue in the profile, and select the entity of the next and the next tongue, and then the computer is arranged in order from the beginning to the end in its database. The amount of thermal shrinkage is important. The second rounded value can be displayed on the computer display and marked next to the corresponding die hole size, so as to comprehensively evaluate the length of the work belt without Look up from the database because the computer has determined the reasonable layout of the die holes, which provides favorable conditions for the modification of the work belt. after drawing the geometric shape of the cross-section It’s quick and easy.Introduction Extrusion technology is a younger technology compared to rolling and forging, but it has a history of more than 200 years.
Machining the die hole working belt on the CN EDM wire cutting machine, cutting the graphite electrode on the CN graphite forming machine, and then processing the die exit belt on the CN EDM forming machine and forming different working belt lengths. When extruding flat, wide, thin-walled profiles (such as wall panels) with a simple single-hole die (plane die), the size of the die hole in the middle of the profile must be larger than that of the periphery (see
, the width W and width-to-thickness ratio W/t of the profile are different , Sometimes even as large as 3~4mm) Whether it is a single line or a variety of lines, the size of the die hole is gradually reduced from the center to the end of the profile. If the offset is not compensated, errors will occur in the wall thickness of the profile at the tail of the die tongue. After the length is calculated, they should be comprehensively analyzed and evaluated to see if the difference between them exceeds the allowable range
. The length is precisely calculated, so the calculated value can be rounded to the decimal point. The more complicated the die tongue, the more advantageous it is to use computer-specific software to locate and compensate for the correction. In addition, the design of the die hole size also needs to consider the compensation of the shrinkage of the profile cross section during stretching and straightening. Comprehensive analysis of the stress and strain fields and temperature and velocity fields of the middle mold makes the mold production a controllable process.
