Problems solved by technology

The embedding copper nuts produced by turning method mainly have the following deficiencies and defects: the utilization rate of raw materials is low; because the turned copper must contain lead, so the embedding copper nuts are non-green environmental protection products, which have been restricted by the international community
Yet the rivet nut that this prior art prepares is only applicable on sheet metal parts, then can't be applicable on the board material that is widely used day by day such as plastics, bakelite

Embodiment Construction

[0027] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings: this embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation modes and specific operating procedures are given, but the scope of protection of the present invention is not limited to the following Mentioned examples.

[0028] Such as figure 1 As shown, the cold forging embedded nut involved in this embodiment specifically includes: a nut mouth 1, a neck body 2, an embedded body 3, and a nut tail 4. The neck body 2 is located between the nut mouth 1 and the embedded body 3, respectively. Between the embedded body 3 and the nut tail 4, the outer part of the embedded body 3 is provided with an axial groove 5.

[0029] The inner edge of the nut mouth 1 is provided with a trumpet-shaped opening, and the angle between the opening and the horizontal plane is α=60°.

[0030] The embedded body 3 has ...

Abstract

The invention discloses a cold-headed embedded nut in the technical field of cold heading manufacturing and a manufacturing method thereof. The cold-headed embedded nut comprises a nut mouth, neck bodies, a nut tail and an embedded body, wherein the neck bodies are positioned between the nut mouth and the embedded body and between the embedded body and the nut tail respectively; an axial groove is arranged outside the embedded body; and the outside diameter of the neck body is less than the outside diameters of the nut mouth, the nut tail and the embedded body. Compared with the prior art, the manufacturing method is more saving and environment-friendly; the cold heading process carries out production by adopting leadless environment-friendly materials at room temperature, and has higher production efficiency and lower energy consumption as compared with turning process; moreover, the overall strength of the nut is increased when the density of the nut is improved after cold heading machining; and the precision of the cold heading process completely meets the requirements of the machinery manufacturing industry.

Description

Technical field [0001] The invention relates to a product in the technical field of cold heading manufacturing and a manufacturing method thereof, in particular to a cold heading embedded nut and a manufacturing method thereof. Background technique [0002] Since the birth of special embedded copper nuts for plastics in the 1950s, the turning method has been used to produce embedded copper nuts all over the world for more than half a century. However, the embedded copper nuts produced by turning methods mainly have the following shortcomings and defects: the utilization rate of raw materials is low; since the copper material processed by turning must contain lead, the embedded copper nuts are non-green and environmentally friendly products and have been restricted by the international community. . When the embedded copper nut is produced by the precision cold heading process, there is no deficiency and defect of the turning method at all: the utilization rate of raw materials is ...
