Product details
 Hot melt drilling machineThe drill bit is made of tungsten carbide material, which has undergone the most advanced heat treatment process and can operate at high speed and rotate at high temperatures, Maintain high hardness and wear resistance under vertical pressure. When high-speed rotation comes into contact with the metal surface that needs to be processed, it instantly reaches a high temperature of 600 degrees, softening the gold at high temperatures To increase the elongation performance of metals, it is possible to achieve processes such as drilling, reaming, and tapping.
working principle:
1. The high-speed rotating hot drill contacts the surface of the workpiece and generates high temperature by friction with the metal surface.
2. The rapid feed of the hot drill in the automatic drilling and tapping machine generates pressure, and the high temperature can instantly soften the surface of the workpiece locally.
3. While hot drilling and squeezing through, stretch the softened metal part into a metal sleeve that is four times its original thickness.
4. High temperature softening does not change the structural properties of metal materials, and the entire process only takes 2-6 seconds.
5. Squeezing wires and forming threads on metal bushings.
6. The extruded threads can withstand high-strength tensile and torsional forces.
The advantages of hot melt drills
1. Improve production efficiencyQuick drilling and rapid lining forming, the entire process only takes 2-6 seconds. The molded liner can be directly extruded with threads; Replace life
Welding nuts or rivet nuts with complicated production processes.
2. Improve product qualitySimplify the process flow and make it easy to operate; High precision of hole positioning; The extruded thread has high tensile and torsional strength.
3. Reduce production costsEasy to operate and master, no need to purchase equipment, replacing expensive welding processes.
4. Clean and environmentally friendly, without debris.
5. Save materials.
The so-called automatic drilling and tapping machine is a composite process, which can be simply described as' one-time clamping, multi process processing '. Production requires efficiency and precision
The degree detection and compensation functions demonstrate the advantages of automatic drilling and tapping machines.
