High-speed precision stamping technology is an advanced manufacturing technology for modern stamping production, which integrates high-speed precision press technology, high precision variable stamping die technology, high-quality product material technology, intelligent control technology and green as an integrated high-tech. The application of high-speed precision stamping technology for mass production of products has the characteristics of high production efficiency, high quality, high consistency, energy saving, labor saving, cost reduction and safe production, etc. Therefore, it has been paid more and more attention by all industrial production sectors of national economy. At present, modern advanced manufacturing technology is the theme of research and development in the world, especially in today's highly developed market economy, it occupies a very important position.
High-speed precision stamping die technology is mainly based on the use of plate processing products, and consists of three basic elements: high-speed press equipment, precision stamping dies, and high-quality coil material, and is connected with the uncoiling device, leveling device, feeding device, material lubrication device, discharging device, managing device, and receiving device of the automation peripheral equipment, and is a kind of stamping automation production line that is combined according to the stamping process.
Stamping automation can not only greatly increase labor productivity, improve labor conditions and reduce costs, but also effectively ensure personal safety in stamping production and fundamentally change the face of stamping production, so it is widely used in the fields of electronics, communications, automobiles, machinery, military industry, light industry, electrical appliances, instruments and meters, medical equipment, automation equipment and home appliances manufacturing. It is also being used more and more widely in the manufacturing fields of rail transportation, aerospace, new energy and other products.
With the rapid development of the technology of products such as electronic communication, electrical appliances, automobiles and home appliances, the demand for precision stamping parts is getting bigger and bigger, and the technical requirements are getting higher and higher, and the applications are getting wider and wider, so in mass production and super mass production, ordinary presses can no longer meet the production and technical requirements. Adopting high-speed precision presses for high speed, automation and continuous stamping is an effective way to improve stamping productivity. Since the number of ram strokes per minute of high-speed precision presses is more than 5 times higher than that of ordinary presses with similar tonnage, high-speed precision presses not only have high precision and good surface quality of stamped parts, but also have long die life.
In recent years, stamping technology has continued to develop in the direction of high speed, precision and intelligence, advancing the development momentum of high-speed presses, and as a result, many high-speed precision presses and ultra-high-speed precision presses have emerged. In the load condition, it can also reach the extra precision requirement in its standard. This marks the development of high-speed precision press technology to the ultra-high-speed ultra-precision technology stage.
Some foreign companies of small tonnage high-speed precision presses are divided into four speed levels according to the number of slider strokes: normal speed ≦ 250 times / min, secondary high-speed 250 ~ 400 times / min, high-speed 400 ~ 1,000 times / min, ultra-high-speed ≧ 1,000 times / min. Large tonnage high-speed precision press slider stroke number is relatively low, such as 300 tons of large high-speed precision press, the slider stroke number range is only about 160 ~ 400 times / min, 100 tons of fins special high-speed precision press, the slider stroke number range is generally about 150 ~ 250 times / min.
Since the stamping speed varies with the tonnage of the press, the length and number of ram strokes, the structure and material properties of the product, the speed and accuracy of the automatic feeding, it is difficult to use a simple number as the boundary to classify each grade. The press speed that is 5 to 10 times higher than the speed of ordinary presses is generally referred to as high-speed precision stamping. From the application of high-speed precision presses in most Chinese enterprises, the speed of punching is more reasonable and meaningful according to the average value of the minimum and maximum number of slider strokes or the speed of punching which is 10~20% higher than the average value. Because the highest number of strokes of high-speed precision press slider is generally refers to the number of strokes without load. When the number of strokes up to a certain value, the press in the operation of the imbalance phenomenon is significantly increased, the dynamic degree of change in the slider under the dead point is also greater, so it is necessary to solve a series of technical problems such as roll quality, feeding speed, die performance and life, equipment strength, rigidity and accuracy, automatic monitoring and stability of failure, vibration and noise, as well as lubrication and cooling system. Therefore, the speed of punching times in high-speed precision press applications is quite critical.
The technology of high-speed precision stamped parts is characterized by many varieties, material diversity, thin plate coiled material, great automated production batch, high precision, complex shape, high technical content and added value.
High-speed precision stamped parts can be divided into electronic parts, IC IC lead frames, motor cores, electrical cores, heat exchanger fins, automotive parts, home appliance parts, and other types according to the industry, application and process characteristics. The parts mainly include connection devices, connectors, brush parts, electrical terminals, flexible parts, etc.
IC IC lead frame mainly contains discrete device lead frame and IC lead frame.
Motor cores mainly contain single-phase series-excited motor cores, single-phase household motor cores, single-phase shaded-pole motor cores, permanent magnet DC motor cores, industrial motor cores, plastic stator cores, etc.
Electrical cores mainly include E transformer cores, EI transformer cores, I transformer cores, and other transformer cores, etc. Heat exchanger fins mainly include industrial heat exchanger fins, household heat exchanger fins, automotive heat exchanger fins, etc.
Auto parts mainly include auto structural parts and auto functional parts.
Home appliance parts mainly contain large appliance parts, such as color tube electronic gun parts, and small appliance parts, various types of structural and functional parts, etc.
Other parts mainly include instrumentation parts, IT parts, acoustic and camera parts, modern office parts, and hardware parts, etc.
The weight of the machine body determines the upper limit of the impact pressure of the high-speed press. Lightweight body will inevitably limit the impact pressure of high-speed presses, shorten the service life, and even leave some safety hazards.
High-speed high-speed punching machine configuration, for example, the same 25-ton high-speed punching machine, high and low configuration price difference of hundreds of thousands of dollars. Specific can be compared from the following aspects.
The use of manipulators or flap buttons
Whether to install a two-hand start panel
Whether to install manual oil pump
The use of standard electric box or simple electric box
The use of copper core motors or aluminum core motors, etc.
Manufacturers with different processing precision use different processing equipment and process products with different clearance fits. Needless to say, the quality of the products processed by full CNC machining and ordinary machine tools are naturally higher and the finishing cost is naturally higher.
