Embodiment

[0018] Using a laser forming machine, the laser beam with a power of 5-12kw is focused on the inner surface of the tire mold to be processed through the light guide system to form a laser molten pool; after being focused by the light guide system, the diameter of the laser spot is 0.1-1.5mm. Under computer control, the laser spot scans circularly at a linear speed of 60-100m / min, and at the same time the laser spot scans up and down at a speed of 0.1-10m / min to complete the scanning of the inner surface of the tire mold. During the scanning process, the powder feeding device Feed metal powder into the laser molten pool, and the metal powder is melted in the laser molten pool. After the laser spot is scanned, the molten metal solidifies, and a metal layer is clad on the inner surface of the tire mold; the tire pattern is layered by the computer and according to The position of the tire pattern is controlled by the computer to turn on and off the laser beam, and a layer of patter...

Abstract

The present invention provides one tyre mold making layered laser fusing-on process. The layered laser fusing-on process adds required material in the practically required thickness without redundant part to form the tyre mold pattern, and has saving in material, low cost and short making period.

Description

technical field [0001] The invention relates to a method for manufacturing tire molds, in particular to a method for manufacturing tire mold patterns with laser technology. Background technique [0002] At present, the manufacturing methods of tire molds on the market are all manufactured by mechanical processing and EDM. The above-mentioned method is manufactured by adopting a removal method, that is, a subtraction method, to remove redundant metal materials. Because the pattern on the tire—that is, the groove volume only accounts for 10-20% of the entire tire surface volume, that is to say, for the tire mold, 90-80% of the metal will be removed to finally manufacture the tire mold. The disadvantage of this manufacturing method is that the manufacturing cycle is long, high-quality metal materials and energy are wasted, the cost is high, the technology is difficult, and it is almost very difficult to change the pattern after the tire mold is manufactured. [0003] How to s...
