Metal Stamping Die
The forming of metal stamping molds is a very important processing method in the manufacturing industry. The process of metal stamping molds involves bending techniques such as deep drawing, bulging, flanging, and punching.
Metal Stamping Tool And Die
Metal stamping tool and die is a workpiece formed by placing metal materials into a stamping machine. This type of die is classified based on the type of operation carried out by the tool. Stamping die involves many metal manufacturing processes, such as stamping, cutting, and bending using a press. In the process of a press, the mold that completes one stamping process is a single-process mold. There is also a composite mold, which is a mold that can complete multiple stamping processes in each press stroke, although it is on one workstation.

The Process of Metal Stamping Tool and Die
1.Bending Process
Bending is the process of stamping a material to a specified shape and angle. Bending parts have many shapes, mainly including V-shaped workpieces, and U-shaped workpieces, There are other types of O-shaped workpieces as well. According to the different shapes required for the workpiece, corresponding processing methods should be used. Each processing method has a different degree of bending. Even though the bending methods are different, their processing and deformation advantages have similar patterns. V-shaped bending is one of the most common metal bending services that can meet various bending requirements.
The characteristics of bending deformation:
The bending process involves high-precision bending of metal materials to meet the shape and size requirements of the components. The bending process of molds can reduce the generation of metal waste and implement efficient production.
2.Deep Drawing Process
Deep drawing is a process that utilizes metal materials for processing. Generally, pressure is applied to metal materials, and the blank of the deep drawing die is punched into a specified shape. When the pressure is applied by a press, the flat raw material will be processed into the required depth of components. This process is commonly used in deep metal workpieces, including automotive parts, household appliances, etc.
3.Punching Process
Blanking is a stamping process that involves separating the raw materials through the concave and convex molds inside the stamping die. Blanking can be divided into two processes: material cutting and punching. Blanking is the process of cutting a die along a specified contour, with the lower part being the workpiece. Punching refers to the identification of parts outside the contour as punched parts by a die. The most commonly used mold in the process of material cutting and punching is the punching die.
4.Forming Process
Metal stamping tool and die forming is a process in which deformation occurs under the action of the die, and various local deformation methods are used to change the workpiece into a specified shape. The forming methods include: flipping, punching, undulating forming, bulging, necking, etc.
Flipping: It can be divided into concave flipping and convex flipping.
Bulging: A stamping process in which tubular raw materials are passed through a mold to expand radially outward. When bulging, the material will be subjected to tangential tensile stress, and the degree of deformation caused by bulging will be limited by the ultimate elongation of the raw material.
Shrinkage: It is a process of reducing the diameter of a workpiece that has already been drawn. In the process of necking, the tangential stress of raw materials reduces the diameter of the workpiece and increases its thickness.
Flaring: Flaring is a machining process that increases the diameter of the top of a hollow workpiece.
Fluctuation: Fluctuation deformation is a processing procedure that applies the extension of raw materials to create local concavity or convexity in the workpiece. In the process of undulating machining, the thickness is naturally formed and there is no fixed thickness.
Leveling: Leveling is a machining method that can enhance the straightness of all or part of flat components. In the process of stamping molds, this process is usually carried out after punching. Generally, stamping workpieces undergo the process of leveling.
Assembly of Metal Stamping Tool and Die
Metal stamping tool and die is composed of multiple components, and the processing conditions and level may impose certain limitations on the processing of the components. If there are significant processing errors, it will reduce the accuracy of assembly. Operators need to improve the level of assembly technology to ensure high precision and quality in the assembly of stamping molds.
- Assembly Method
There are two main assembly methods, one is the direct assembly method and the other is the coordinated assembly method. These two methods have different performance. The direct assembly method has the advantage of high efficiency, and high-precision processing equipment can ensure the quality of the mold to a certain extent. Although there is no high-precision equipment, the use of assembly methods can also produce stamping molds with high-quality characteristics.
- Assembly Steps
The assembly of metal stamping tool and die must be done very carefully, and operators must be familiar with and master the assembly process to avoid reassembling the stamping molds in the future, effectively improving production efficiency and improving the quality of the stamping molds. The assembly steps of stamping molds include:
1.When assembling, it is necessary to first select a suitable reference component. Determine the reference part based on the machining of the main parts of the stamping die. The reference part has many parts, such as convex and concave molds, convex molds, concave molds, etc.
2.Overall accessories.The parts and components are assembled into a complete metal stamping mold, and the order of each referenced part must be correct.
3.Component assembly. This refers to the assembly work where multiple stamping die components are processed into one component according to specified requirements.
4.Adjust the gap between the convex and concave molds. The control methods for the gap between the convex and concave molds include measurement method, light transmission method, paper cutting method, gasket method, copper plating method, and adjustment using a process locator.
5.Inspection. Check whether the metal stamping tool and die meet the requirements and ensure the accuracy of assembly. If there is any problem with the produced workpiece, it needs to be adjusted until it meets the requirements.
Maintenance Methods for Metal Stamping Tool and Die
Pre-use inspection of the mold: Check if there are any damaged components in the metal stamping tool and die, check if the mold is installed correctly on the stamping equipment, and whether the upper and lower mold pressing plate bolts are tightened. Check if the stamping equipment that meets the requirements is used.
Inspection during mold use: Before opening the mold equipment, ensure that the inside and outside of the mold are clean and undamaged. And it is also necessary to ensure a clean environment, without external factors affecting the operation. When making a metal stamping tool and die sample, it is necessary to first check for any areas that do not meet the requirements. If any areas do not meet the requirements, adjustments should be made promptly. During the use of the metal stamping tool and die, the operator should provide comprehensive lubrication to the surface of the metal stamping mold product according to the operating requirements, and promptly dispose of the waste. If the metal stamping tool and die experience punch breakage and bending during use, it is necessary to replace the damaged parts with standard components.
Surface strengthening of the main forming components of the Metal stamping tool and die is beneficial for enhancing the wear resistance of the metal stamping tool and die surface, and the quality of precision stamping molds will also be improved.
In the process of metal stamping tool and die, molds play a very important role. However, unexpected situations may occur, so the mold may be damaged. In metal stamping processing, attention should be paid to avoiding the influence of these factors, which helps the normal operation of the metal stamping tool and die and increases its service life.
Metal stamping tool and die is a complex process that uses stamping machines to stamp metal materials into specified shapes. There are many types of metal materials, each with different properties, and complex-shaped components are manufactured through stamping.
