The upper die of the bending machine has different angles of 90 degrees, 88 degrees, 45 degrees, 30 degrees, 20 degrees and 15 degrees. The lower die is generally divided into 400 mm, 200 mm, 100 mm, 50 mm, 40 mm, 20 mm, 15 mm and 10 mm, with a total of 835 mm.
Punch manufacturers remind stamping customers to pay attention to the above problems when using high-speed fine punch to ensure personal safety. Today we discuss the factors that affect the geometric accuracy of the punch.
The structure of the punch is simple, which is much simpler than that of the electric punch. The transmission device of the punch is the external hand rocker arm and the internal transmission gear. During processing, the operator rotates the flywheel through the hand rocker arm to realize
It is reported that China's machine tool industry has developed so far and has a relatively perfect industry foundation. However, China's CNC machine tool has developed for a short time and started relatively late. It is still far behind developed countries. At present, CNC machine tool has been an indispensable
