Precision stamping is a metal forming technology. The stamping process is used in order to create shapes and features on metal sheets. The stamping process can be used to bend sheets, punch holes in sheets, shear and shear form metal sheets or parts. Traditionally, it has been referred to only as metal stamping. Precision stamping press can be adapted to manufacture a wide range of industrial products, but the process must be well understood before it can be employed. This article discusses what precision metal stamping is and the benefits of using a precision press instead of a conventional press, and tells you how to choose a precision press
Precision metal stamping is a metal forming technique that is performed using an automated precision metal stamping press. The process involves impacting the sheet metal with a punch or die to bend and stretch the sheet metal. In this process, the precision stamping press is automated or programmed to repeatedly stamp the sheet metal with a specific force. The sheet metal is deformed due to the shear forces applied by the punch or die, resulting in bending, punching or sheet metal stretching.
The process of precision stamping depends on the type of sheet metal, the properties of the sheet metal, and the capabilities of the precision stamping press machine. There are two types of machines commonly used, which vary depending on the quality of the metal stamping.
Along with machining, die casting, forging and many other examples, precision metal stamping is a standard and ubiquitous manufacturing process. Some of its major benefits include
Precision metal stamping dies tend to be less expensive to produce and maintain than dies used in other common processes.
Cleaning and plating precision stamping presses is cheaper than similar treatments for other metal forming technologies.
Precision metal stamping presses are relatively easy to automate and can employ high-end computer-controlled programs that provide higher accuracy, faster production and quicker turnaround times.
Precision stamping press is suitable for a variety of production processes such as stamping, embossing, multi-sided stamping, shearing and bending, deep punching and fine blanking.
The selection of precision stamping press equipment is an important element in stamping process and die design, which is directly related to the safe use of stamping equipment, the realization of stamping process, and important issues such as die life, product quality, production efficiency and cost. The selection of stamping equipment for precision presses includes the selection of equipment type and the determination of equipment specification.
The selection of the type of precision press stamping equipment is mainly based on the characteristics of the stamping process and factors such as productivity and safe operation. In the production of small and medium-sized stamping parts, open type presses are mainly used; for the blanking process of thin materials, precision presses with accurate guidance are preferred; for the stamping process of large deep-drawn parts, deep-drawing presses are preferred; in mass production, high-speed precision presses should be used; for the stamping process that does not allow the die guide to leave the guide column, eccentric presses with adjustable stroke are preferred; for the stamping process that requires large deformation force (such as cold extrusion), eccentric presses with adjustable stroke are preferred. for stamping processes requiring large deformation force (such as cold extrusion, etc.), a rigid and more precise machine should be used.
After determining the type of precision punching machine, the specifications of the press should be determined according to the size of the stamping part, the size of the stamping part and the size of the die, and the following main technical parameters should be considered in general.
Nominal pressure (rated pressure) refers to the maximum action allowed on the slide at a certain distance from the lower dead center, or at a specific angle instantaneously.
Nominal pressure is an important technical parameter of precision presses. In use, for simplicity, for stamping processes with a small force stroke (such as punching, falling material, etc.), a press with a nominal pressure greater than the sum of the required process forces for stamping can be used directly. For stamping processes with larger force stroke (such as deep drawing, deep bending, etc.), precision stamping should be selected according to the condition that the sum of process force required for stamping is less than or equal to 50% to 60% of the nominal pressure of the press.
