Products Description
The hot melt drill is a tapered tool made of special tungsten carbide. It uses high speed rotation and high axial pressure to generate a large amount of frictional heat on a thin tube or plate, where the material at the point of processing is in a "super plastic" state and the tool displaces and shapes this part of the material to form a bushing. The height of the bushing can be 3-4 times the thickness of the original workpiece.
Hot melt drill is widely used in automobiles, motorcycles, construction, decoration, machine tools, machinery, aerospace electronics, electrical appliances, furniture, waterways, shipbuilding and automation equipment and other aspects.
Classification of hot melt drill:
1.According to the surface requirements of the workpiece, the hot melt drill bit can be divided into round hot melt drill and flat hot melt drill.
Round hot melt drill:
The hot melt drill penetrates the workpiece and forms a convex ring on the surface of the workpiece while stretching the forming bushing. This boss is suitable for screw seal or nut washer.
Flat hot melt drill
The middle step of the hot melt bit is grinded with the cutting edge of a milling cutter. When the hot melt drill penetrates the workpiece to form a bushing, the convex ring of the workpiece surface is cut off (milling and chamfering), so that the surface of
the workpiece is smooth.
the workpiece is smooth.
2. According to the thickness of the workpiece, hot melt drill is divided into short hot melt drill and long hot melt drill.
Short drill: Used for commonly use thin-walled parts. Suitable for penetrating workpiece thicknesses of 0.8mm-3mm. The cylindrical part of the drill is short, and the hole after extrusion into a conical shape can make the tapping strength stronger.
Longer drill: Used for thicker workpieces or when straight holes need to be processed. It is suitable for tapping workpieces with a thickness of 3-12mm. The cylindrical part of the drill bit is longer and the hole formed after extrusion is longer.
Longer drill: Used for thicker workpieces or when straight holes need to be processed. It is suitable for tapping workpieces with a thickness of 3-12mm. The cylindrical part of the drill bit is longer and the hole formed after extrusion is longer.
