Stamping process and application areas
Stamping processing is a production technology that utilizes the power of conventional or stamping equipment to directly deform the sheet metal in the mold, thereby obtaining the shape, size, and performance of product parts. Sheet metal, molds, and equipment are the three essential elements of stamping processing. Stamping processing 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. The mold used for stamping parts is called a stamping die, abbreviated as a punching die. A stamping die is a tool used to process materials (metal or non-metal) in batches into the required stamping parts. Stamping dies are crucial in stamping, and without qualified dies, mass stamping production becomes difficult; Without a punching die, the stamping process cannot be achieved. Stamping technology, molds, stamping equipment, and stamping materials constitute the three elements of stamping processing, and only by combining them can stamped parts be obtained.
Stamping processing
1. Determine the amount of deformation compensation based on materials, product structure, etc,
2. Design molds to punch finished or semi-finished products based on compensation amount
3. Processing semi-finished products to finished products
4. Adverse phenomena include cracking, wrinkling, pulling, uneven thickness, and non formability during tooth tapping and thread processing
1. Drill the diameter of the bottom hole for internal threads first (the size of the bottom hole is determined according to the thread specifications, search online for a large number); First, process the outer circle of the external thread to the size of the larger diameter of the thread (determine the size according to the thread specification, search online for a large number)
2. Machining threads: Use corresponding grade taps to tap internal threads; External threads can be turned with a thread cutter or threaded with a die set
3. Adverse phenomena include loose threads, inconsistent sizes, and unqualified thread gauge inspections. Materials such as copper, aluminum, and low carbon steel with low deformation resistance, good plasticity, and good ductility are mainly selected according to usage requirements. As for inspection standards, they should be formulated according to product requirements. Thread inspection has national standard thread gauges, and hole inspection can be based on national standard designed plug gauges or purchased national standard size plug gauges.
The application of stamping technology in automotive processes:
The progress of stamping production enterprises is increasingly closely linked to the automotive industry. The manufacturers of stamping machine tools have adjusted their new products and solution concepts to adapt to the development of the automotive industry, and have also integrated this trend into their production strategies.
The enthusiastic stamping production line, the solidification exchange of stamping production lines, the production of large vacuum feeding stamping machines for automotive sidewall production, and the entry of small vacuum feeding stamping machines into the market are all examples of close cooperation between the automotive industry and stamping machine production enterprises.
In the great revolution represented by the diversification of automobile dies and the short cycle of die changes in the world, the manufacturers of stamping equipment have also found Xintiandi to adapt to everyone's retrogression. The diversity of molds enables automotive industry enterprises to provide multiple exemplary cars for production, while also proposing new applications for stamping process skills, bringing about a revolution in frame stamping process skills and automotive panel production processing skills.
In the past, when searching for a revolution in stamping skills, people not only thought about the production of large stamping parts for automobiles, but also about the production of small and micro stamping parts. And the proportion of these small and micro stamped parts in the production of car frames may be roughly 70%. Even though the new generation of these small stamping parts is not as frequent as that of large automotive components, they still have an urgent impact on the diversity of molds during the production process. The diversity of molds not only brings about a reduction in the number of product deliveries, but also a reorganization of the stamping product market structure.
Stamping parts application
(1) Stamping in the automotive industry. Mainly focused on deep drawing. In our country, this part is mainly concentrated in large factories such as automobile factories, tractor factories, and aircraft manufacturing factories, and independent large-scale stamping and deep drawing factories are not yet common.
(2) Stamping of automotive and other industry components. Mainly for punching and shearing forming. Many of these enterprises are classified under standard parts factories, as well as some independent stamping factories. Currently, there are many small factories around some automobile or tractor factories.
(3) Electrical component stamping factory. This type of factory is a new industry that has developed with the development of electrical appliances, and is mainly concentrated in the south.
(4) Daily necessities stamping factory. Make some handicrafts, tableware, etc. These factories have also seen significant development in recent years.
(5) Stamping factory for household appliance components. These factories only emerged after the development of my electrical appliances industry, and most of them are distributed within home appliance companies.
(6) Special stamping enterprises. Stamping for aviation components belongs to this category of enterprises, but these process factories are also classified under some large factories.
