Task commentary

Rolling profiles by hand is a very complicate procedure. This is a tough work when rolling thousands of profiles by hand everyday, and cut down then put into cardboard box when it reaches enough length. On the one hand, machines are running on and on during working procedure. And on the other hand, ever-accelerated extrution and process optimization cause faster production rate. It shows that man-made rolling profiles come under restriction.

In recent years, industrial brain trust have been thinking how to use automatic operation instead of hand operation. In spite of this, there are only several solutions in market for now. So far there is not a kind of machine that can roll or cut different kinds of profiles. Sand profile have been thinking about make this procedure become optimized, then understand the specific design untill the implementation of internal mechanical engineering of special machine.

Firstly, detailed instruction of specification and catalogue of products’s concept were made based on the needs of equipments. Meanwhile essential pionts are:

• rolling speed at least 30m/min
• allowed typical dimension of profile is 40mm×40mm
• freely design unit length
• automatically cut length

the structure happened in our company based on these demands, and absorb details for last time. The result is perfect. Element’s drawing also is inventory map at the same time. Our toolmaking procedure has integral elements of products and acquire other elements. We spent about 4 weeks in mechanical assembling for integral elements including aerodynamics. The following 3 weeks we assemble circuit. Recently we are testing initiating stage of equipments.

After all these tests, this equipment will used for produce elastic rubber before oct. 1st, 2007.
