Stamping molds are the basic equipment for production and processing in stamping factories. The processing of a set of finished molds is quite complex, and drilling is the most fundamental link and the basic skill that fitters need to master.

In the processing of Metal Stamping molds, the requirement for drilling accuracy is very high. Controlling the drilling accuracy well can help improve the quality of the mold and produce better quality metal stamping parts. It is necessary to ensure the accuracy of marking, punching, and drilling when controlling precision.

1. Control of bottom hole accuracy

Firstly, control the accuracy of line drawing. Check the sharpness of high standard pins by drawing thin and deep lines in one go.

Then, control the precision of the metal stamping mold processing punch hole. During the process of punching the sample, move the sample along the center of the cross marked groove. When there is a feeling of depression at the top of the sample, it indicates that the sample is in the center of the cross. At this time, the sample needs to be straight, and the operator should lightly tap the sample before punching. After eye flushing, it is necessary to check whether the orientation is accurate. If it is not accurate enough, it is necessary to adjust the parameters and eye flushing tools from scratch. Finally, control the precision of drilling. First, use a drill bit to drill a shallow hole in the marked position of the hardware mold, measure the drilling direction and quality to see if it meets the standards. If it does not meet the standards, repeat the adjustment until it meets the requirements. Stamping processing plants need to pay attention to drill bits with longer cutting edges, which can easily cause the drilling center to be too high. It is recommended to choose drill bits with almost no cutting edges while meeting the drilling requirements.

2. Control of drilling accuracy

The above control of low hole accuracy in molds is to lay the foundation for hole expansion, and it is particularly important to choose a reasonable method to control the accuracy of mold hole expansion.

Firstly, it is necessary to reduce the size of the drilling bit, enhance its automatic centering effect, and continuously reduce the drilling accuracy and cutting force; Secondly, adjust the drilling equipment so that the drill bit gradually approaches the already drilled bottom hole port downwards, and make slight adjustments to completely eliminate the bottom hole from the drill bit edge. Finally, turn on the drilling machine switch and proceed with the mold drilling process.
