The invention discloses a cold heading forming module and method for a flanging riveting nut. The cold heading forming module comprises a feeding die, a sizing die, a guide hole forming die, an octangle forming die, a flange forming die, a threaded-unthreaded hole forming die and a punching die. According to the designed cold heading forming technology, multiple forming dies are adopted to conduct machining step by step from material cutting, and finally, the flanging riveting nut is formed; the cold heading forming method can achieve high-efficiency and continuous production, compared with common machining, the cold heading forming method has the advantage that the size of a blank can be determined according to the size of the nut, losses generated in the production process are extremely small, and the production cost is greatly saved; and the low-cost and high-efficiency cold heading forming method can better promote the product to the market.
Description
technical field [0001] The invention relates to the field of cold heading manufacturing, in particular to a cold heading forming module and a cold heading forming method of a turning rivet nut. Background technique [0002] With the new energy, light weight and connection of different materials in automobiles, the riveting nuts should be developed rapidly. In order to solve the shortcomings of the existing rivet nuts in application, a self-developed and designed flip riveting nut has been obtained in the automotive industry. It is widely used, but because the pre-supply is for the whole machining process, not only the material utilization rate is low, but also the production efficiency is low and the cost is high, which restricts the marketing of the product. In order to promote the product better, it is necessary to design a A low-cost, high-efficiency manufacturing method. Contents of the invention [0003] The object of the present invention is to provide a cold headin...
