Description
Technical Field
The invention belongs to the technical field of metal processing, and particularly relates to a cold press molding die.
Background
The cold press molding is to manufacture a part with a required shape by utilizing plastic deformation of metal, so that the cutting amount can be greatly reduced, and the material utilization rate is improved. The material utilization rate of cold extrusion can reach more than 80 percent. With the progress of scientific technology and the continuous improvement of the technical requirements of industries such as automobiles, motorcycles, household appliances and the like on products, the cold press molding production technology has gradually become the development direction of fine production of small and medium forgings. Cold press forming techniques have a number of advantages over other processing techniques.
First, labor productivity can be increased, and using a cold extrusion process rather than cutting to manufacture parts can increase productivity by several times, tens of times, or even hundreds of times. Second, the workpiece can achieve the desired surface roughness and dimensional accuracy, and cold-extruded parts are rarely reworked, requiring only fine grinding where particularly high demands are made. And thirdly, the cold working hardening of the metal after cold extrusion and the formation of reasonable fiber streamline distribution in the part lead the strength of the part to be far higher than that of the raw material. In addition, a reasonable cold extrusion process can form compressive stress on the surface of the part, so that the fatigue strength is improved. Therefore, after using the cold extrusion process, some parts that would otherwise require heat treatment and strengthening may be omitted from the heat treatment process. Some parts initially need to be made of high strength steel and after the cold extrusion process is used, can be replaced with low strength steel. Finally, cold press molding technology can process parts with complex shapes and difficult cutting, such as special-shaped cross sections, complex inner cavities, inner teeth, inner grooves with invisible surfaces and the like. The cost of the parts is greatly reduced due to various advantages of cold press molding technology.
In addition to the processing of plate-shaped metal materials, the processing of cylindrical metal materials such as tubes and rods is most of the processing of the plate-shaped metal materials, in the processing of traditional cylindrical metal materials, the cylindrical metal materials are required to be manually placed in a lower die of a cold press molding die due to the high gravity center of the cylindrical metal materials, after an upper die descends to the top of the cylindrical metal materials, an operator can loosen the cylindrical metal materials after the upper die and the lower die clamp the cylindrical metal materials, so that the cylindrical metal materials can be correctly entered into the molding die, and the cold press molding precision of the cylindrical metal materials is ensured. However, the operation is dangerous, the hands of operators are easy to be injured, and the safety production accidents can be seriously caused.
