Description
Technical field
The present invention relates to the production field of punch components in manufacturing industry, the component especially produced in batches especially provides one
Method of the kind for repairing die wear
Background technique
Punch components are widely applied in the fields such as track transportation industry, equipment manufacture industry, automobile industry.Due to component
Batch production, die wear are accelerated, and replacement punch die is frequent.And mold procurement cycle overlong time, cost are very high, even if only replacing
Punch-die expense is not also low.
Therefore, long according to existing stamping die procurement cycle, it is at high cost, replace the disadvantages of frequency is more, it is necessary to provide one
Method of the kind for repairing die wear, the mold after making abrasion are reusable.
Summary of the invention
The purpose of the present invention is to provide a kind of methods for repairing die wear, can effective solution buying mold week
The problems such as phase is long, at high cost, and interchangeability is poor, easy to wear.
The technical scheme is that a kind of method for repairing die wear, using electroplating process, its original
Reason is, using plated parent metal as cathode, by electrolysis, to make preplating in plating solution in the saline solution containing pre- plating metal
The cation of metal is deposited in base metal surface, forms a kind of method of surface finish of coating.The present invention using
Plate hard chrome.
Hard chrome is also known as wear-resisting chromium, and hard chromium not only has certain gloss, but also its hardness is high, wearability is good and and matrix
It is firmly combined.
It is described for repair die wear method specifically includes the following steps:
Step 1: cleaning；
Mold after abrasion is removed, it is with rag that its surface wipes are clean, then utilize ultrasonic technology cleaning 10
~20 minutes, make the dirt rapid deterioration in die surface and gap；Purpose is to keep plated item spray coating secured, not easily to fall off；
Step 2: preparing before plating；
Cleaned mold is dried, is wrapped up the place for not needing plating with adhesive tape, the place for needing to be electroplated is naked
It exposes outside；Side is hung on conductive column with iron wire, and the other side is sunk in electrolyte；
Step 3: plating；
Ready plated item is put in the electrolytic solution, using punch die as cathode, electrolyte is anode, and power-on voltage is
220V, time are 2~3 hours, and environment temperature is 55 ± 1 degree, and the thickness of coating being electroplated out is 0.1~0.2mm；Time reaches
Afterwards, it powers off, after workpiece is taken out, dries immediately, measure size and hardness, hardness reach 56~60HRC, is transferred to after qualified
Lower sequence；
Step 4: processing；
The mold that will be electroplated, is processed by drawing, is allowed to tolerance dimension and reaches requirement.
The conductive column is hard chrome stick.
The electrolyte is the chromium sulfate solution being made of chromic anhydride and sulfuric acid, and the mass ratio of the chromic anhydride and sulfuric acid is
100:1, the chromium sulfate solution concentration are 50~150g/L.
The advantages of using this coating: coating crystallization is careful, smooth, thickness is uniform, and coating hardness is high, and wearability is good, smooth
Property is strong, there is preferable heat resistance.
The present invention has following beneficial effect:
1, the mold after wearing, using the technique, can be reused without scrapping.
2, the mould repair time is short, can both complete within 4 hours.
3, mould repair is at low cost, and new mold of purchasing generally wants 1000 yuan/, as long as and repairing 20 yuan/.
4, mold interchangeability is good.
5, properties are all satisfied requirement after repairing.
Detailed description of the invention
Fig. 1 is present invention plating schematic diagram；
In figure: 1, hard chrome stick；2, electrolyte；3, plated item grinding tool；4, coating.
Specific embodiment
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of method for repairing die wear specifically includes following step using electroplating process
It is rapid:
Step 1: cleaning；
Mold after abrasion is removed, it is with rag that its surface wipes are clean, then utilize ultrasonic technology cleaning 10
~20 minutes, make the dirt rapid deterioration in die surface and gap；Purpose is to keep plated item spray coating secured, not easily to fall off；
Step 2: preparing before plating；
Cleaned mold is dried, is wrapped up the place for not needing plating with adhesive tape, the place for needing to be electroplated is naked
It exposes outside；Side is hung on conductive column with iron wire, and the other side is sunk in electrolyte；The conductive column is hard chrome stick；The electrolysis
Liquid is the chromium sulfate solution being made of chromic anhydride and sulfuric acid, and the mass ratio of the chromic anhydride and sulfuric acid is 100:1, and the chromium sulfate is molten
Liquid concentration is 50~150g/L；
Step 3: plating；
Ready plated item is put in the electrolytic solution, using punch die as cathode, electrolyte is anode, and power-on voltage is
220V, time are 2~3 hours, and environment temperature is 55 ± 1 degree, and the thickness of coating being electroplated out is 0.1~0.2mm；Time reaches
Afterwards, it powers off, after workpiece is taken out, dries immediately, measure size and hardness, hardness reach 56~60HRC, is transferred to after qualified
Lower sequence；
Step 4: processing；
The mold that will be electroplated, is processed by drawing, is allowed to tolerance dimension and reaches requirement.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
