Ⅰ.About the speed of High speed precision punching machine
Under high speed, precision is also indispensable, otherwise once the product quality declines, it will be difficult to gain market favor. Therefore, the production process urgently needs corresponding high-speed precision technology as support. High-speed precision stamping technology refers to those production equipment that have both extremely high stamping speed and precision. At present, the international community has not yet given a clear definition of the speed variation range of high-speed precision presses. Generally speaking, those equipment with a stamping speed 5 to 10 times higher than that of ordinary presses are widely called high-speed precision presses.
High-speed precision stamping technology is an advanced manufacturing technology, which is mainly used in the production of sheet metal processing products. It is mainly composed of three core components: high-speed press equipment, precision stamping dies and high-quality coils. In addition, the technology also relies on a series of automated auxiliary equipment, including unwinding devices, leveling devices, feeding devices, discharging devices, sorting devices and receiving devices, etc. These devices are combined into a complete automated production line through precise coordination and connection according to the established stamping process. High-speed precision stamping technology combines high-speed press technology, high-precision mold design technology, high-quality material application technology and advanced intelligent control technology, representing the top level of modern stamping production.
High-speed precision stamping technology has been widely used in many fields such as electronics, automobile manufacturing, optical instruments, industrial automation control and medical equipment due to its significant advantages of high efficiency, excellent quality, high consistency and cost savings. Some high-end high-speed precision presses can achieve 2000, 3000 or even 4000 slide strokes per minute, ensuring that they meet the special precision standards and strict production requirements even under heavy loads.
High-speed operation is accompanied by noise problems. Therefore, noise reduction measures have become an indispensable part, and sound absorption and sound insulation technologies must be used in the workshop to ensure compliance with factory noise control regulations. This shows that the development of high-speed precision stamping technology is not only limited to the advancement of production equipment, but also requires comprehensive consideration of the various impacts it brings. It is really linked together, and the optimization of each link is crucial.
Ⅱ.The relationship between high-speed punching machine stamping speed and stamping accuracy
The stamping speed has a direct impact on the fluidity of metal materials. Specifically, when the stamping speed increases, the fluidity of the metal material will be weakened accordingly, which may cause the final product size to be smaller. On the contrary, if the stamping speed slows down, the fluidity of the material will be enhanced, which may make the product size larger. According to a professional mechanical process research report, every time the stamping speed increases by 10%, the product size may decrease by about 0.5% to 1%.
In the metal stamping process, the stamping speed is an extremely critical factor. It is not only related to production efficiency and cost-effectiveness, but also directly determines the dimensional accuracy of the final product. Therefore, a deep understanding of the impact of stamping speed on product size is crucial to optimizing the entire production process and ensuring product quality.
Product dimensional accuracy is one of the key factors to measure the level of stamping technology. If the stamping speed is not set properly, whether it is too fast or too slow, it will have an adverse effect on the dimensional accuracy of the product. According to a research report in the field of professional mechanical processes, every time the stamping speed increases by 10 percentage points, the final size of the product may be reduced by about 0.5% to 1% due to the corresponding weakening of material fluidity. Therefore, in the actual production process, precise control of the stamping speed is crucial to ensure that the product can meet the expected dimensional requirements.
Ⅲ.How to adjust the punching speed of High Speed Punching Machine to achieve the best punching accuracy
1. In-depth understanding of the properties of punching materials
Before adjusting the punching speed, the first task is to fully understand the physical and chemical properties of the material to be processed. The properties of the material, such as hardness, toughness and thickness, will profoundly affect the deformation mode and the required force during the punching process. For example, soft materials may need to reduce the punching speed to prevent excessive deformation, while hard materials may need to be accelerated to reduce friction and heat accumulation. Therefore, setting the punching speed reasonably according to the material properties is the cornerstone of achieving high-precision punching.
2. Analysis of the structure of the stamping die
Mold design is also a key factor in determining the punching speed. The precision, clearance and edge shape of the die will have a profound impact on the forming effect and precision of the stamping parts. When the die is well designed and the manufacturing precision is high, the punching speed can be appropriately increased to improve efficiency; on the contrary, if the die has defects or insufficient precision, the speed needs to be reduced to prevent damage to the die or the quality of the stamped parts from declining. Therefore, when adjusting the punching speed, the actual condition of the die must be taken into consideration.
3. Establish scientific stamping parameters
After clarifying the material properties and mold design, scientific stamping parameters need to be established, including stamping speed, stamping force and stamping stroke. Among them, the regulation of stamping speed is particularly important. Generally speaking, high-speed stamping can improve efficiency, but it may also lead to problems such as uneven material deformation and increased mold wear; while low-speed stamping can improve accuracy, it will reduce efficiency. Therefore, it is necessary to set the speed reasonably according to production needs and material properties under the premise of ensuring accuracy.
4. Implement practical testing and adjustment
After setting the parameters, it is necessary to verify their effects through practical testing. By comparing the accuracy and quality of stamping parts at different speeds, gradually adjust to the best state. At the same time, it is necessary to pay close attention to mold wear and abnormal conditions during the stamping process, and make timely adjustments and optimizations. For example, when the mold wears too fast or cracks appear on the stamping parts, it may be necessary to reduce the speed to reduce impact and friction; when the production efficiency is too low or the accuracy is not up to standard, it may be necessary to increase the speed and optimize the mold design.
5. Continuous monitoring and maintenance
To maintain the best working condition and punching accuracy of the High Speed Punching Machine, continuous monitoring and maintenance are also indispensable. This includes regular inspection of die wear, cleaning of the punching area, and adjustment of parameters. Through continuous monitoring and maintenance, problems can be discovered and solved in a timely manner, ensuring that the punching machine is always in excellent working condition.
