Description

Structure for combining head portrait and body of figure copper handicraft

Technical Field

The utility model relates to a copper handicraft manufacturing field specifically is a structure that personage copper handicraft head portrait and health combine.

Background

Modern copper artware, particularly copper portrait, is processed by adopting an investment casting method in order to improve the overall value of the artware because the head has more lines and more complex shapes. Investment casting includes wax pressing, wax trimming, tree assembling, slurry dipping, wax melting, molten metal casting, post-treatment and other processes, a casting obtained by investment casting has high dimensional precision and surface smoothness, the investment casting can enable facial expressions of copper figures to be vivid, and a casting with a complex shape can be poured, but the investment casting process is complex, a large amount of materials such as paraffin are required to be consumed, the efficiency is low, the rejection rate is about 20%, and the investment casting is applied to production of mass copper artware, so that the production cost of enterprises can be increased. Compared with investment casting, the die casting can improve the yield and efficiency of products during mass production and processing. Because the die-casting needs to consider the demolding and the copper-liked facial expression obtained by die-casting is not as good as that of an investment casting, the investment casting cannot be replaced by the casting obtained by die-casting in the field of copper-made artware processing with a complex shape, but for parts with simple shapes such as a body and the like, the overall production efficiency of the artware can be improved by flexibly applying the die-casting on the premise of not reducing the overall quality of the artware, and the enterprise cost is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at above problem, provide a structure that personage copper handicraft head portrait and health combine, can improve the production efficiency and the finished product yield of copper portrait article.

In order to realize the above purpose, the utility model adopts the technical scheme that: the hollow shell structure comprises a body end and a head portrait end, wherein the body end is produced by adopting a die-casting process to obtain a hollow shell structure with open upper and lower ends because the external lines are simpler; and the head portrait end can not adopt a die-casting process but adopts investment casting because lines such as five sense organs, a hairstyle and the like are complicated, the head portrait end and the body portrait end are assembled after being independently cast, in order to avoid exposing a connecting part after the body end and the head portrait end are assembled into a whole, a counter bore is arranged at the connecting part of the body end and the head portrait end, the outer diameter size of the neck part of the head portrait end is slightly smaller than the size of the counter bore, so that the neck part of the head portrait end can be inserted into the counter bore, and then the head portrait end and the body end are fixedly connected through welding, gluing and the like.

Furthermore, in order to make the head portrait end and the body end difficult to separate, the head portrait end and the body end are fixedly connected in a welding mode, for convenience of processing, a through hole is formed in the lower end of the counter bore and is communicated with the interior of the body end, and a welding gun enters the body end from the lower end of the body end to perform welding processing, so that a welding seam is located on the inner side of the body end.

Further, in order that the welding gun head can contact the joint of the body end and the head portrait end, the inner diameter of the neck of the head portrait end is smaller than that of the through hole.

Furthermore, an alloy welding rod is arranged on the bottom wall of the counter bore, and the melting point of the alloy welding rod is lower than that of the body end and the head portrait end.

Furthermore, in order to prevent the alloy welding rod from moving, a groove is formed in the bottom wall of the counter bore, the alloy welding rod is clamped in the groove, and the upper end face of the alloy welding rod is higher than the bottom wall of the counter bore.

Furthermore, the positioning columns and the positioning grooves which are matched with each other are arranged at the bottom wall of the counter bore and the lower end of the head portrait end, so that the body portrait end and the head portrait end cannot be dislocated or deviate when being assembled.

The utility model has the advantages that: the body end and the head portrait end are cast separately, the body end adopts a die-casting process with high efficiency and yield, and the head portrait end is independently processed, so that the die structure can be simplified, and the production yield can be improved.

1. The head portrait end is inserted into the counter bore of the body end and then connected together in welding and other modes, so that processing marks such as a connecting part and a welding seam can be hidden, the attractiveness of the copper portrait product is ensured, and the overall quality of the product is improved.

2. Through the process, as only the head portrait end needs to be subjected to investment casting, the production efficiency is greatly improved by more than 3 times, and the rejection rate cannot exceed 5%.

3. Because the head portrait end has smaller volume and mass compared with the whole handicraft, the probability of industrial injury in the production process is greatly reduced. Since the technical improvement, the applicant has not caused any accidents such as pressure injury, scalding and the like.
