Problems and precautions in continuous stamping die production

Zhongshan Yingyun Hardware, as a professional metal stamping parts supplier, will introduce to you the common problems of continuous stamping die processing.

Continuous stamping die is a kind of cost-saving and high-efficiency. The products are usually high-precision and large-scale, and are the choice of many precision stamping parts manufacturers. Today, Zhongshan Yingyun Hardware will take you to understand several common problems in continuous stamping die production, avoid the occurrence of the following situations, and help to produce good stamping products and high processing efficiency.

Stamping Products

Common problems of continuous stamping die production:

1. Spring loss of precision stamping parts

The easy damage of the die spring is a problem that is easily overlooked in production. Different precision stamping parts require different strength dies, so the springs of continuous stamping dies also need regular maintenance and replacement. We have also seen many colleagues basically do not repair or even replace the mold, and even when the mold is damaged or the size is offset, the reason is not found.

2. The punch of continuous stamping die wears fast

This happens when the gap between the continuous stamping die is too small. Poor alignment of the convex and concave dies, insufficient accuracy of the die guide components and die bases, etc., will lead to unsmooth discharge of the forming die. After long-term uninterrupted production of the punch, the punching needle of the die is overheated, which is easy to cause the punch temperature to be too high and the wear to be accelerated. The precision of the machine tool mold is not high, and the punch needle deviates from the upper mold, which will cause damage to the punch and die. Inaccurate die sharpening methods also tend to cause the continuous stamping die to wear faster.

3. The neutrality of continuous stamping dies usually has the following problems

The design and precision of the continuous stamping die cannot meet the requirements.

The mold design gap is unreasonable.

The precision of the guide sleeve of the die punch is not enough.

Die wear after long-term use leads to poor neutrality.

The mold mounting seat of the upper and lower turntables of the machine tool is poorly aligned.

Precision stamping continuous stamping dies are produced in coil material, with low material waste rate, flexible engineering and structural design, multiple pieces can be punched at one time, fast production speed and high efficiency. The same set of molds can produce a variety of products, which is easy to automate, saves manpower and material resources, reduces the number of equipment, molds and workshop area, and saves the transfer and storage of semi-finished products.

Precautions for continuous stamping die processing:

1. It is necessary to confirm the material, thickness and grain direction of the material, whether the dimensions and tolerances of the finished drawing are well marked, what angle method is used for the view, and which size is used for marking.

2. The size setting of the continuous stamping die should be logical during design, and the lower limit should be set for the L-shaped forming and unfolding size. For stamping parts that need to be electroplated, it is necessary to consider the dimensional changes before and after plating, and then expand the design.

3. It is necessary to consider the setting of the gap value of various materials in order to obtain a more reasonable size during the mold test.
