Abstract
The invention discloses a kind of processing method that metal pattern is repaired in the ceramic industry thermospray that is used for, pine in advance in spraying, broken through traditional Heating temperature, thereby make door metal spray-coating method can be used for the cutting edge reparation of the metal pattern of glaze for glazed tile, rehabilitation cost is lower more than 80% than present common restorative procedure, and improve 2～3 times than life-span of new die, have outstanding economic benefit.
Description
The present invention is the processing method that is used for a kind of thermospray repairing mould of ceramic industry, is mainly used in to repair the metal die of producing glaze for glazed tile.
At present, what the mould repair of production glaze for glazed tile generally adopted in the ceramic industry is mechanical system, being about to bad matrix, to process (include rammer, Bao, grind, mill, operations such as grinding, carburizing and quenching) its technology again various, the cost height, and every reparation once, mould will reduce by 2 millimeters, then will scrap so a matrix can only be repaired 5-6 time, and waste of material is also bigger.The method for spray coating alloy that someone attempts that mechanical industry is used is transplanted and is used, but it is inapplicable that test shows, major cause is: common spraying coating process is that parent is warmed to 300～400 ℃, then welding powder (being alloy powder) is sprayed onto on the parent, be warmed to fusing point more gradually, make the bonding one of welding powder and parent.Like this, because the beginning preheating temperature is lower, and the cutting edge area of mould repair face is little, and welding powder is difficult to be attached on the repair surface, also just can't finish the reparation task.
It is low to the purpose of this invention is to provide the simple cost of a kind of renovation technique, the processing method that can repair the metal pattern of glaze for glazed tile many times.
The object of the present invention is achieved like this, mirror is borrowed the method for existing machinery industry spraying alloy powder, after its technology transformed, be used for the reparation of the metal pattern of glaze for glazed tile, at first processed parent metal mould is preheated to 800～1200 ℃ with spray welding gun, breaking through conventional preheating temperature (300～400 ℃) makes parent that good adhesive force be arranged, again alloy welding powder is sprayed on the machined surface, further coating fusing, make metal welding powder and processing parent be molten into one, heap is even rapidly, and promptly spraying coating process is finished, so handle through naturally cooling, the mill trimming is multiple.
The present invention makes significant advantage than prior mechanical renovation technique, and operating procedure is simple, and repair time is short, and cost is low, and can repair many times, and because the alloy strength of welding powder is generally higher, so the die life after repairing also is multiplied.
The present invention is described in further detail below in conjunction with embodiment:
Accompanying drawing is a mould cut-away view of the present invention.
Example 1, pressure type metal powder surfacing torch (rifle) is preheated to 800 ℃ with to be repaired 2 of mould 1 in the use, opens the switch that dusts of surfacing torch, sprays the alloy powder of Ni40, and the short period of time heats and makes the coating fusing, and alloy powder and mould fuse into one, and heap is even, stops welding.Mould naturally cooling with after welding polishes repair surface 2, grinds R face 3, and reparation finishes.
Example 2 is preheated to 1000 ℃ of alloy powders that spray Ni50 with repair surface 2, and other technological process is with example 1.
Example 3, repair surface 2 is preheated to 1200 ℃, sprays the alloy powder of CO40, other technological process is with example 1.
Test shows, adopts mould repair method provided by the invention, can shorten three times of man-hours, and cost descends 80%, improves 2～3 times work-ing life.
Claims (2)
1, a kind of processing method of repairing metallic mould of enamelled ceramic brick by thermal spraying coating is characterized in that: be that first face to be repaired with metal pattern is preheated to 800 ℃～1200 ℃, spray powdered alloy again, the coating fusing, heap is even, then through the air naturally cooling, after grinding, attrition process reparation.
2, processing method according to claim 1 is characterized in that: the optimum Preheating Temperature that metal pattern is to be repaired is 1000 ℃.
