Abstract
A kind of disintegration processing technology of tire-mold.The method for brazing that the present invention proposes is made the technology of tire-mold, adopts the argentiferous intermediate temperature solder, and pattern block and die body is welded together, makes tire-mold, and the soldering processes process comprises the soldering heating, determines brazing temperature, selects brazing flux and solder, steps such as postwelding cleaning.The present invention has overcome the low shortcoming of existing mechanical processing technique mould and die accuracy, has improved the tire-mold quality.
Description
The present invention relates to a kind of processing technology of tire-mold, be applicable to the manufacturing of tire-mold tyre sulfuration mould, particularly be suitable for the various fortune tires of taking advantage of, heavy duty tire, the manufacturing of cycle tyre and tractor tire sulfurizing mould.
Machining process is generally adopted in existing tire-mold manufacturing, and its skill process is: blank material → vehicle chamber → mill colored type → pincers worker to repair flower → brill pore → finished product.The shortcoming of this technology is: milling Hua Jisuo, to mill the decorative pattern geometry inconsistent, the mutual alignment precision is low, the cavity dimension error is big, it is big that colored type processing capacity is repaiied in pincers worker, long processing time, place, decorative pattern dead angle can't polish, and each repairs regional curved surface difference whole die cavity, causing the entire die die cavity is not smooth curved surface but polyhedron, thereby has influenced tire quality.
The objective of the invention is to overcome the above-mentioned shortcoming in the prior art, propose a kind of weldering flower, the tire-mold manufacturing process of sticking flower.
Technical process of the present invention is:
The characteristics of talking technology are that tire-mold blank and pattern block are carried out the machining and the special process respectively, make it to reach technological requirement, are connected afterwards, and decorative pattern and shell are become one, and are delivered for use after the assembling.
Pattern block connects the employing method for brazing with die body, after the welding position of pattern block and the die body cleaning soon, with solder two parts soldering is integral (showing as Fig. 1).With soldering is the weldering of pattern block and die body the heating means that the technology of one comprises soldering, brazing temperature determine the selection of cored solder and brazing flux, several processing steps such as postwelding cleaning.
The heating means of soldering
The mode of heating of soldering is according to being heated and local heat by the different branches integral body with pattern kind of the size of welding mould.Whole heating is with welded part, and whole air-heating furnace or the vacuum furnace of placing of formwork that promptly fits together and decorative pattern is heated to brazing temperature, and the cooling of coming out of the stove after being incubated 30-90 minute.
Local heat comprises resistance heated, eddy-current heating and flame heat.Resistance heated will add an operating current between soldered pattern block and formwork, utilize both contact resistance heating solders and the welding position between two workpiece, reach brazing temperature, finish the soldering of mould, eddy-current heating is to utilize middle and high frequency induction heater to soldering, soldered pattern block and formwork carry out the local eddy-current heating of welding position, reach brazing temperature, finish the soldering of mould, flame heat then is to utilize the acetylene flame that above-mentioned part is carried out local heat, reach brazing temperature, finish the heating of mould.
Determining of brazing temperature:
Usually between 350 ℃-850 ℃ (showing as Fig. 2), when adopting whole the heating, temperature determines that between 350 ℃-650 ℃ when adopting local heat, temperature is determined between 650 ℃-850 ℃ to brazing temperature.
The selection of brazing flux and solder:
Brazing flux is formed by boric acid and potassium chloride mixed preparing, and ratio is: boric acid 25%-40%, potassium chloride 75%-60%, liquid brazing flux is coated in the welding position, and thickness is not more than 0.02 millimeter, and solder is based on intermediate temperature solder, serviceability temperature is between 350 ℃-850 ℃, and silver content is no more than 60%.
Postwelding cleans:
Behind the heat tracing, cooling is cleaned with sodium nitrite in aqueous solution afterwards, and natrium nitrosum concentration is 10%-20%.
Compare with prior art, the present invention has simplified technology, has alleviated heavy physical labour, has reduced the tire-mold manufacturing cost, can make the tire-mold of some curve complexity, has guaranteed the high-quality of tire product.The old mould that technology of the present invention can utilize tire plant to scrap removes old decorative pattern, more renews decorative pattern, thereby is reclaiming waste and old raw material, and there is marked improvement the aspect that reduces production costs.
