Tool forming and coating device

The invention relates to a tool forming and coating device, in particular to a complex forging process by combining the material of the designed plate material to form a tool body structure, and further combining an outer covering layer with the outer surface of the tool body by injection molding. To save costs and cost.

In general, the wrench tool has to withstand the large operating torque, so the basic raw materials for the construction must consider the steel demand of the structure and must use the expensive steel, which has made the cost upward; and the manufacturing process uses the forging method. In addition, the manufacturing process requires the straightening, cutting, heat treatment, compression molding, and forging of the rough metal steel to be quite complicated; for example, it is necessary to reproduce the coarse embryos produced by the hot forging. After cold forging, the shape is formed by mechanical processing such as lathe cutting and milling machine punching, and then the structure is strengthened by heat treatment. After other polishing treatment, the surface of the tool is smooth and protected by electroplating. Rust, the overall process is complex and complicated, and the cost is huge.

In addition, the size of the wrench is different, so the price varies with the size, especially the smaller the size of the tool, although the production process is the same as other tools, and the production process and equipment It is also similar, but in the production process, it is necessary to set a small size in the above-mentioned manufacturing process, and these small size changes often occur at a cost that the machine cannot grasp; for example, in heat During the processing, small-sized tools are relatively easy to deform during the heat treatment due to small size and structure problems, and the small-sized tool handles that have been heat-treated are bent by more than 180 degrees, so that the straightening steps need to be added separately. It can be said that it is an increase in cost; in addition, the small-sized tool cannot be stably hung due to the small size of the tool when it passes through the heat treatment furnace, and the small-sized tool is easily deformed by heat, so it is often dropped and deposited in the furnace. At the end, it causes loss of non-performing rate, making the cost difficult to control, and very inconsistent with economic benefits.

In view of the above difficulties, some manufacturers can reduce the material cost of the wrench tool steel by fitting the outer surface of the wrench tool with the design of a jacket without affecting the torque load of the wrench. In order to reduce costs.

However, because it is combined with the outer casing of the wrench tool and the body of the wrench tool in a tying manner, a large gap is formed and it is not easy to be firmly combined, which may cause swaying and slipping when the operation is performed. And inconvenience.

Moreover, because the wrench tool itself does not change the high-cost process of complicated processing such as straightening, cutting, heat treatment, compression molding and forging of the rough metal steel in the process; only by combining with the outer casing can reduce The material cost is not significant.

Therefore, how to deal with the above-mentioned difficulties in the current tool structure manufacturing, which cannot be effectively reduced, and the existing structure of the casing through the casing can have troubles and shortcomings in use.
