Description

Technical Field

[0002] Turret slitting shears are usually used in automated equipment to cut metal sheets into multiple thin sheets. The disc blade is one of the frequently used and vulnerable parts. The traditional replacement method requires disassembling the machine and then replacing the blades one by one, which is time-consuming and labor-intensive. Therefore, a more convenient disc blade replacement device is needed. A quick disassembly device is set at the connection between the disc blade and the shearing machine to facilitate users to replace the disc blade. The disc blade is locked to the shearing machine through a rotary mounting mechanism, and the angle change of the center of the disc blade is fully utilized to adjust the cutting angle.

[0003] However, when the longitudinal cutting unit is changing the tool during the process, the tool change time is long and the equipment occupies a large area due to the large structure of the main disc shear and the large space for auxiliary operation of the tooling. The design and manufacture of this disc blade changing device requires the use of high-precision parts and special process requirements, so the cost is relatively high. There are multiple components and connecting parts, and regular inspection and maintenance are required to ensure its normal operation. The disc blade changing device speeds up the speed of blade replacement, but the machine still needs to be suspended during the replacement process, which will result in longer production downtime.
