CUT-OFF TOOLS FOR COLD HEADING MACHINES

CUT-OFF KNIFE FOR COLD HEADING MACHINES

The cut-off tool of the cold heading machine consists of a cut-off matrix and a cut-off knife. The cutting knife is used to obtain a measured workpiece. The quality of the cut workpiece depends on the quality of the knife.

We manufacture machine tools for cold heading machines, including cut-off (cut-off dies and cut-off knives) according to the customer's drawings.

In addition, we have the ability to design various machine tools and machine tooling according to the drawings of finished products and the technical requirements of the customer.

To do this, it is necessary to clarify the size of the seats for machine tooling, the model of the cold heading machines used and the diameter of the wire used for upsetting fasteners, hardware and parts.

During fastener-making production, after the wire has been successfully drawn to size, it enters the inside of the cold heading machine. It then goes through a cut-off die and continues until it reaches a wire stop. At this point, a cut-off knife moves across the wire, cutting it off to a specific length.

wire cut-off during cold heading — A specific length of wire is cut off from a coil of wire prior to going into the heading die.

Typical Cut-off Knife Drawing

Cut-off knives can be designed to cut wire of different diameters and lengths, making them suitable for a range of cold heading applications. This increases production flexibility and efficiency.
