Application and Characteristics of Hardware Stamping Parts - XieHuang Metal Hardware


Hardware stamping parts are formed by applying external forces to plates, strips, pipes, and profiles using a press and mold, causing plastic deformation or separation, in order to obtain the required shape and size of the workpiece (hardware stamping parts).

Hardware stamping parts are formed by applying external forces on plates, strips, pipes, and profiles using a press and mold, causing plastic deformation or separation, in order to obtain the required shape and size of the workpiece (hardware stamping parts). Stamping and forging both belong to plastic processing (or pressure processing), collectively known as forging. The stamping blanks are mainly hot-rolled and cold-rolled steel plates and strips. Stamping is mainly classified by process and can be divided into two categories: separation process and forming process.

Hardware stamping parts are mainly formed by stamping metal or non-metal sheets with the pressure of a press and forming them through stamping molds. They mainly have the following characteristics:

⑴ Hardware stamping parts are made by punching with minimal material consumption. The parts are lightweight, have good stiffness, and the internal structure of the metal is improved after plastic deformation of the plate, resulting in an increase in the strength of the hardware stamping parts.

⑵ Hardware stamping parts have high dimensional accuracy, uniform and consistent dimensions with the same module, and good interchangeability. No further mechanical processing is required to meet general assembly and usage requirements.

During the stamping process, metal stamping parts have good surface quality and a smooth and beautiful appearance due to the fact that the surface of the material is not damaged. This provides convenient conditions for surface painting, electroplating, and other surface treatments.

Feature application

Hardware stamping parts are a production technology that utilizes the power of conventional or specialized stamping equipment to directly deform the sheet metal in the mold, thereby obtaining a certain shape, size, and performance of product parts. Sheet metal, molds, and equipment are the three elements of stamping processing. Stamping is a method of metal cold deformation processing. So, it is called cold stamping or sheet metal stamping, abbreviated as stamping. It is one of the main methods of metal plastic processing (or pressure processing), and also belongs to material forming engineering technology.

50% to 60% of steel is made from sheet metal, with the majority being finished products that have been stamped and pressed. The body of a car, radiator fins, steam drum of a boiler, shell of a container, iron core silicon steel sheets of motors and electrical appliances are all stamped and processed. There are also a large number of hardware stamping parts in products such as instruments, household appliances, office machinery, and storage containers. Stamping is an efficient production measure, using composite molds, with the exception of multi-station progressive molds, which can complete multiple stamping technology operations on a single press and automatically generate materials. Fast generation speed, long rest time, low production cost, collective production of hundreds of pieces per minute, loved by many processing plants.

Hardware stamping parts have the characteristics of being thin, uniform, light, and strong compared to castings and forgings. Stamping can produce workpieces with reinforcing ribs, ribs, coils, or flanges that are difficult to manufacture with this familiar hand diameter, in order to improve their rigidity. Due to the rejection of rough molds, the workpiece accuracy can reach the micrometer level, with high accuracy and consistent specifications, and can be stamped with holes, protrusions, etc. In actual production, process tests similar to the stamping process, such as deep drawing performance tests, bulging performance tests, etc., are commonly used to inspect the stamping performance of materials, in order to ensure the quality of finished products and high qualification rates.

In addition to forming thick plates using a hydraulic press, stamping equipment usually uses a condensing press. Focusing on the current high-speed multi-station condensing press, equipment configuration such as uncoiling, finished product collection, and delivery, as well as mold storage and quick mold replacement placement, and the use of computer style tube bundles, can form a passive stamping production line with high production rates. Under the condition of producing dozens or hundreds of hardware stamping parts per minute, completing stamping and production processes in a short amount of time often leads to personal, equipment, and quality issues.
