1. Mold factors
Selection of mold materials: The performance of mold materials directly affects its service life and the forming quality of stamping parts. Reasonable mold material selection should take into account the strength, wear resistance, toughness of the material, as well as the characteristics and output requirements of the processed material. For example, for high stress areas, high-strength and high-wear-resistant materials should be selected to improve the forming stability and service life of the mold.
Strength design of mold structural parts: The strength design of mold structural parts is directly related to the stability of stamping part forming. During the design process, it is necessary to perform necessary strength verification calculations on the mold structural parts to ensure that they can withstand sufficient loads without deformation or damage during the stamping process.
2. Stamping material factors
Material properties: The properties of stamping materials, such as strength, toughness, ductility, etc., directly affect the forming quality and stability of stamping parts. Materials with different properties require different stamping processes and mold designs.
Material thickness and volatility: The thickness of the material and its volatility have a certain impact on the quality stability of stamping parts. Slight changes in thickness may lead to inconsistent dimensions of stamping parts, which in turn affects their assembly and use performance.
Variation range of materials: Variation range of materials includes material composition, organizational state, etc. These factors may also affect the forming stability and quality of stamping parts.
3. Process parameter factors
The size of tensile rib resistance: In the deep drawing process of stamping parts, the size of tensile rib resistance plays a very important role in quality stability. Reasonable tensile rib resistance can ensure the uniform flow of materials in the die and prevent defects such as wrinkling and rupture.
Variation range of blank holder force: The size of blank holder force and its variation range also affect the forming stability of stamping parts. Appropriate blank holder force can keep the material in a stable position in the die and prevent the material from moving or deforming during the stamping process.
4. Lubricant factors
Selection of lubricants: Whether the selection of lubricants is reasonable directly affects the stability of stamping parts processing and the service life of stamping dies. Suitable lubricants can reduce friction and wear between the die and the material, reduce energy consumption during stamping, and improve the forming quality of stamping parts and the service life of the die.
5. Other factors
Equipment accuracy and stability: The accuracy and stability of stamping equipment are also important factors affecting the stability of stamping parts. Insufficient precision or poor stability of the equipment may lead to inconsistent dimensions or shape defects of stamped parts.
Operator skill level: The operator skill level also has a certain impact on the stability of stamped parts. Skilled operators can accurately control process parameters and operating procedures to reduce the impact of human factors on the stability of stamped parts.
The stability of the water intake pontoon is affected by many factors such as mold material, stamping material, process parameters, lubricant, equipment accuracy and operator skill level. In actual production, these factors need to be considered comprehensively and corresponding measures should be taken to ensure the stability and quality of stamped parts.
