Select metal stamping material material precautions

Metal stamping parts are made of stainless steel, iron, aluminum, copper and other materials and deformed or broken by punching and die to achieve a certain shape and size. If the material is not selected, it is easy to produce defective products, resulting in high cost!

Metal stamping parts material selection issues to pay attention to:

1. In the specification of steel plate, whether it is a fixed-length plate or a coiled plate, the same material and thick material have different roll widths and different selling prices. Therefore, in order to reduce costs, it is necessary to work hard from the formulation of the procurement volume width, and try to select the volume width interval without increasing the price under the premise of ensuring the material utilization rate. For example, if the size of the fixed-size board is selected as appropriate, after the steel mill is finished, it is not necessary to perform secondary shearing to reduce the cutting cost. For the coiling board, try to select the coil forming specification and process of the unwinding forming, and reduce the number of times. Cut the workload and improve work efficiency.

2, the thickness of the sheet has deviation requirements, usually within the allowable range of deviation, should first select the lower deviation of the sheet.

3. Determining the shape and size of the sheet material of the stamping part is the premise for analyzing the degree of deformation of the stamping part, designing the craft and formulating the technical procedure. If the shape of the sheet is suitable, not only the uneven distribution of the deformation along the sheet material can be significantly improved, but also the forming limit can be improved, and the height of the lug can be reduced, and the trimming margin can be reduced. In addition, for some parts that are directly formed after blanking, if accurate sheet shape and size can be given, the number of times of mold adjustment can be reduced, thereby shortening the production cycle and increasing productivity.

4. When selecting product materials, avoid using high-grade materials to cause over-performance of the products. At the same time, under the premise of meeting the requirements of products and processes, try to select the materials and materials used in the existing mass-produced models to form a material platform. Facilitate subsequent procurement and inventory management. For example, the key performance requirement of ordinary cold-rolled sheets is their drawability, so try to choose low-grade materials in accordance with the requirements of product quality.
