Abstract
The invention discloses a center shaft component for locks of cargo container production technique with investment moulding. The invention provides with a set of rational technique from material selecting, shell making, melting, and heat processing, resolving the many technique problems in center shaft component for locks of cargo container production with investment moulding, simplifying the production procedure and lowering the cost, enhancing productivity so to be more adaptive to mass production.
Description
Technical field
The present invention relates to a kind of lockset manufacture method, particularly a kind of manufacture method of container special lockset axis base part.
Background technology
Along with the development of international trade, the demand of container is very huge, and the respective episode vanning is also increasing with the demand of lockset.And as container with stressed maximum in the lockset, axle base part that requirement of strength is the highest, still follow the technology of using repeatedly forging and molding, reprocessing at present because operation is many, workload is big, the difficulty of producing in enormous quantities is bigger.Cause product cost can not to be in any more.
Model casting claims " lost-wax casting " again.This method is that easy fusible pattern material is injected die mould (mould), makes fusible pattern, and it is assembled into module, and the liquid coating that is made into refractory material and cementing agent in the module surface applied spreads fire-resistant sand grains again on coating then, makes it to harden into shell subsequently.So repeated multiple times just forms the multilayer shell.With the shell heating, the fusible pattern fusing is flowed out, housing toward wherein pouring into liquid alloy, solidifies after operations such as cleaning promptly obtain foundry goods after roasting.Its main technique flow process following (referring to accompanying drawing):
A. wax-pattern is made
Comprise processing steps such as technological design, die mould design, die mould manufacturing, the preparation of mould material, system fusible pattern and running gate system (promptly make product wax sample and design and produce rational running gate system), fusible pattern combination according to products characteristics.
B. shell mould is made
Comprise coating preparation, hardener preparation, coat and stucco, shell sclerosis and dry (stucco and dry two steps repeat to have sufficient intensity with making for several times), the molten processing steps such as fusible pattern (dewaxing), shell roasting that lose;
C. alloyage material
Comprise furnace charge preparation and alloy melting;
D. alloy material melting, cast;
E. cleaning
Comprise shelling, remove processing steps such as dead head, cleaning, check, soldering;
F. heat treating castings;
G. put in storage
Comprise check and correction and warehouse-in.
This foundry goods once-forming, any surface finish, size are more accurate, can reach few cutting or not have the purpose of cutting, are particularly suitable in the production of middle-size and small-size, thin-walled class and the multiple alloy-steel casting of complex-shaped class.And in the manufacturing of container relatively complicated for shape, that requirement of strength is high,, do not use this method at present as yet owing to be subjected to the traditional handicraft restriction with lockset axle base part.
Summary of the invention
The objective of the invention is to provide a cover utilization investment casting method to produce the technology of container with lockset axis base part, full form casting process is replaced Forging Technology produce high-strength container with the many technological problemses in the lockset axis base part to solve, to simplify the production and processing operation of container with lockset axis base part, enhance productivity, reduce production costs, under the prerequisite of guaranteeing specified intensity and quality, be more convenient for producing in enormous quantities.
