Precision metal stamping parts company, what to do when the burr height is uneven during stamping processing []

For precision metal stamping parts companies, during stamping processing, the gap will be too large or too small, and the height of the burr will increase. Among them, the gap is too large, resulting in triangular burrs, the thickness increases, and the gap is too small, and the burrs are thin and high, resulting in secondary shear. Xiaoshuo will analyze with you: Reasons: 1. The gap is partially inconsistent. 2. The sag of the cutting edge causes local deviation. 3. Due to the eccentricity of the mold, the burr height will be inconsistent with half, a. Mold installation is not good, b. The guide post is not well assembled. Solution: 1. After deburring, when the shape of the cut section of the product is uneven, it is because the gap is partially too large or too small, so it needs to be corrected. 2. The cutting edge is locally worn, or due to poor quenching hardness, local collapse occurs, and the root of the burr increases, so grinding is required. 3. The punch and the die are not concentric. This is because half of the shear section is too large and half is too small. This is easy to understand. If it is the reason that the mold or the guide post is not well assembled, just adjust it. However, if the position of the mold core changes during each stroke, it is because the mold assembly part is loose, and the mold core needs to be removed to tighten the correction port. 4. Due to the thrust force during punching, there will be disagreements. When the side bearing block or the guide plate is under force, in order to ensure the accuracy, the guide rail must be used. However, after the guide column is used, if the concentricity is not good, it is because of the poor quality of the guide column. Hardware, 15 years of ingenuity and focus on precision metal stamping parts company, 20000+ sets of stamping die customization production experience, monthly 100+ sets of mold processing capacity, 3 million punching times per day, stamping accuracy up to 0.01mm, 16 quality inspection layers are strict check. It can quickly solve the stamping accuracy problem for you, solve the urgent problem of time, and solve the problem of production quality. Choose, choose rest assured!
