AI Technical Summary

Technical Problem

Existing cutting tools are prone to wear and tear when cutting sheet materials, which reduces tool life and machining accuracy, resulting in high equipment downtime, poor batch consistency, and difficulty in meeting high-precision machining requirements.

Method used

The device employs a slitting mechanism, including a blade pad structure and a cutting assembly. By setting a cutting reference surface and a blade setting reference surface, it ensures that the blade accurately contacts the reference surface. Combined with the material pushing assembly, it achieves accurate positioning and cutting of sheet materials, reducing wear.

Benefits of technology

It improves the positional accuracy and cutting precision of the slitting process, extends the tool life, reduces unnecessary wear on the equipment, and enhances the overall reliability of the machine.

Abstract

The application discloses a slitting device which comprises a knife pad structure, a pushing assembly and a cutting assembly. The knife pad structure defines a placing area, a rear thrust surface, a through hole, a cutting reference surface and a tool setting reference surface. The pushing assembly comprises a pushing piece and a first driving mechanism. The pushing piece can push against the front surface of a sheet material and make the cutting protrusion extend into the through hole. The cutting assembly comprises a cutter and a second driving mechanism. The cutter comprises a cutter body which defines a cutting alignment surface and a cutter seat which defines a tool setting alignment surface. The cutter body extends downward into the through hole to cut off the cutting protrusion. The knife pad structure and / or the cutter can move forward and backward to make the tool setting alignment surface abut against the tool setting reference surface and the cutting alignment surface abut against the cutting reference surface. The application can improve the position accuracy in the slitting process, thereby improving the slitting quality on one hand and reducing the unnecessary wear degree between the knife pad structure and the cutter body on the other hand, and finally improving the use reliability of the whole machine.
