Problems Easily Arise in Deep Drawing Process of Metal Stamping Parts

Stamping parts refer to the method of forming and processing workpieces (stamping parts) with the required shape and size by applying external force to plates, strips, pipes and profiles through presses and dies to produce plastic deformation or separation. Stamping and forging belong to plastic processing (or pressure processing), known as forging. Stamping blanks are mainly hot-rolled and cold-rolled steel plates and strips.

DueMetal Stamping PartsThe shape and size of the product in the stamping process are different, and different stamping processes are required, and deep drawing is one of them. In the actual drawing production, some problems are easy to appear, which affect the product quality and processing efficiency. Please refer to the following points for specific problems of metal stamping parts.

1. The wear of the mold will cause the inner diameter of the drawing piece to be too large

2. If the jacking force is too large, the inner diameter will become larger. Insufficient will cause the inner diameter of the drawing piece to become smaller.

3. If the stretching material is too thin, the inner diameter of the stretching part will become larger; too thick will cause the inner diameter to become smaller

4. The hydraulic oil temperature used for drawing is too high or oil leakage will cause the inner diameter of the drawing piece to be too small

5. The mouth of the elastic sheet is easy to wrinkle

6. Tensioning of the tensile part

7. The appearance of tensile parts has scratches and abrasions

Stamping dies for metal stamping parts are the necessary process equipment for stamping processing.Metal Stamping Partsplays an important role in the processing and production. In this article, we will discuss the operator's operating requirements when the stamping die leaves the machine in the stamping part manufacturer. See 6 points below. Be sure to remember and follow this operation to avoid damaging the mold.

1. Before pulling the stamping die, confirm that the material belt support plate at the feed port of the die has been loosened and removed.

2. When the mold cannot be pulled, one person can pull outward and one person can push backward. Or, after the screw hole of the lower mold base is wound with the mold lifting screw, you can lift it a little bit with both hands at the same time, and then pull it out.

3. When the mold is pulled away from the punch, the mold car must not rotate too fast to prevent the guide plate or material support plate from hanging on the sound insulation cover of the punch or punch, thereby damaging the mold parts or the mold sliding.

4. If the mold drops abnormally, jog operation is not allowed, especially after the mold height stop column is filled with plastic.

5. After lowering the mold, turn off the press host and other power supplies to avoid wasting resources.

6. When the mold stops normally, move the mold slowly until the guide pin enters the belt round hole. It is strictly forbidden to stop the mold at the bottom dead center, which will easily reduce the service life of the spring in the mold.

What technical requirements should the raw materials of metal stamping parts meet in the factory production, what are the performance indicators of the raw materials of the stamping parts, and how to control the cost of metal stamping parts from the aspects of raw materials. These are all about raw materials and have already been written in the previous edition. If you are interested, you can search them. In short, under the consideration of economic efficiency, we should choose the right raw materials to produce products with good quality and customer satisfaction.
