A manufacturing method of weld nut made of stainless steel plate capable of manufacturing a weld nut of a small size generally known as a micro-screw of thin type and nominal thread diameter of about M1.6 easily by blanking and processing a stainless steel plate, and a blanking punch to be used in this manufacturing method. The manufacturing method of weld nut made of stainless steel plate includes a step of blanking and processing a tap drill hole 22 in a stainless steel plate material 20 having a thickness nearly equal to the height of the nut, a step of forming a nut main body 23 by blanking a nut outer shape in the material 20 around the tap drill hole 22, and simultaneously forming a plurality of weld protrusions 24 in the outer circumference of the bottom of the nut main body 23, and a step of processing female threads 25 in the inner circumference of the tap drill hole 22 of the nut main body 23. A blanking punch 5 used in blanking and processing of the nut outer shape is provided with a plurality of notch recesses 8 for forming weld protrusions 24 in the outer circumference of the lower end.
Description
technical field [0001] The present invention relates to a method of manufacturing a weld nut that is thin and has a small thread diameter (nominal diameter around M 1.6, generally called a micro thread) manufactured by punching a stainless steel plate, and a punch used in the manufacturing method . Background technique [0002] When assembling mobile phones and various other small electronic devices, for example, rivet nuts made of stainless steel and with small thread diameters (nominal diameters around M 1.6) are riveted and bonded to thin plates of about 0.4mm in thickness and also made of stainless steel. and use the rivet nut to screw various parts or components on the above-mentioned mounting substrate. However, in the case of using a rivet nut, it is unavoidable that the cylindrical portion used for the caulking joint protrudes slightly on the back side of the above-mentioned mounting substrate. On the other hand, as the thickness of mobile phones and other small el...
