The specific process of stamping production and its two common problems

Stamping parts require specific knowledge and content in production, so we need to learn, understand, and master them in order to have a concrete understanding of stamping parts production and be able to carry out practical operations well, in order to produce high-quality stamping parts with good performance.

1. Steps and processes of stamping production

For the production of stamped parts, the specific steps and processes mainly include:

Step 1: Determine the reasonable and correct amount of deformation compensation for stamped parts based on the material used and product structure.

Step 2: Based on the determined compensation amount, design the relevant molds, and then punch out semi-finished or finished products.

Step 3: Further process the stamped semi-finished or finished products, mainly checking for defects or adverse phenomena such as wrinkling, pulling, and cracking. Also, whether the thickness of the finished product is uniform and whether its molding effect is good. If there are any problems, they should be dealt with and resolved in a timely manner.

2. Tapping and threading during the production process of stamped parts

For the tapping and threading processing in the production process of stamped parts, it mainly involves two aspects: internal threads and external threads.

For internal threads, it is generally necessary to drill the diameter of the bottom hole and perform machining on it. The size of the bottom hole is mainly determined based on the thread specifications. For external threads, it is necessary to perform thread turning with a thread cutter or threading with a die. In addition, some specific issues should be noted during this process, such as inconsistent dimensions and unqualified thread gauge inspection.

3. Common problems in the production process of stamping parts

In the process of stamping production, there are some common problems, so let's give an example below.

Wear on the cutting edge: The specific reason may be due to excessive tensile stress on the material, which causes distortion and flipping of the stamped parts.

Deformation of the end of the convex die blade: For this problem, the cause may be insufficient punching force, resulting in the end being trimmed into a slope or arc shape, which leads to deviation in punching size, such as excessive size. Furthermore, a series of problems such as deformation occurred at the end of the convex die blade.
