What kind of shock absorber should I choose for high-speed punch?
Machinery Product Consultation 1.Choose a shock absorber that has a very high shock absorption effect. Because the tonnage of a high-speed punch is generally 25T, the impulse force is relatively large, so in the choice of shock absorber, you must choose the shock absorber that can bear such impulse, and the shock absorption effect should reach 100%. Above 80 is more suitable. 2.The shock absorber with damper is preferred because the working speed of high-speed punch is very fast, which is dozens of times or even more than 100 times of ordinary punch. The vibration caused by punching at such a speed is bound to cause resonance. It is well known that long-term resonance is very harmful. It will not only cause damage to your plant, but also severe vibration will have a serious impact on the life of your equipment itself and the mold. 3. it is best to choose a shock absorber with a relatively low natural frequency at 3HZ. Because the speed of the flywheel is very fast when the high-speed punch is operating at high speed, it can generally reach more than 500 revolutions or even faster, so choose a low-frequency one. The shock absorber can avoid the resonance zone to make the operation of the high-speed punch more stable.
The development history of the punch
Maintenance, research and development: punch presses, machinery equipment, general machinery equipment, automation equipment, machinery accessories; sales: punch presses, Stamping die market situation my country's stamping dies have made great progress in terms of quantity, quality, technology, and capabilities. However, compared with the economic needs of Guofa and the world’s advanced level, there is still a big gap. Some large-scale, precise, complex, Long-life high-end molds are still imported in large quantities every year, especially cover molds for mid-to-high-end cars, currently still relying mainly on imports. Some low-grade simple stamping dies have become oversupply, and the market is fiercely competitive. The brief introduction of my country's stamping die market in 2004 is as follows: According to statistics released by the China Die & Mould Industry Association, my country’s total output of stamping dies in 2004 was approximately 22 billion yuan, of which exports were 75 million US dollars, or approximately 620 million yuan. From the above figures, it can be concluded that the total size of China's stamping die market in 2004 was about 26.66 billion yuan. The domestic market demand was 26.04 billion yuan, the total supply was about 21.38 billion yuan, and the market satisfaction rate was 82%. In the above overall situation of supply and demand. , There are several specific circumstances that must be explained: First, most of the imported molds are large-scale precision molds with high technical content, while most of the export molds are medium and low-end molds with low technical content. Therefore, the high-tech medium and high-end mold market meets The rate of satisfaction is lower than the overall satisfaction rate of stamping dies. The development of these dies has lagged behind the production of stamping parts. The international market is much lower and has a certain degree of competitiveness. Therefore, its prospects in the international market are promising. In 2005, the export of stamping dies reached 146 million U.S. dollars, an increase of 94.7% over 2004. , Taiwan-funded, and foreign-funded enterprises are developing rapidly in China. A large number of self-produced and self-used stamping dies in these enterprises have no exact statistics, so they cannot be included in the above figures.

What is a high-speed punch lock?
Mechanical equipment use: crank press: its mechanical model is the crank connecting rod mechanism. To adjust the closing height, you can adjust the length of the connecting rod and the length of the crank. Adjusting the length of the crank not only adjusts the closing height, but also adjusts the stroke of the slider. The crankshaft press is to adjust the length of the connecting rod, and the eccentric punch is to adjust the length of the crank (in the punch, it is the eccentric sleeve). Adjust the closing height of a small crankshaft punch: first loosen the screw used to fix the connecting rod nut on the connecting rod, then use a large board to rotate the nut on the connecting rod, and then tighten the screw fixing the connecting rod nut. Adjustment of the closing height of the large crankshaft punch press: Press the button to make the nut on the connecting rod driven by the motor rotate. Eccentric punch: loosen the screw that fixes the eccentric sleeve, adjust the eccentric sleeve, and then tighten the screw that fixes the eccentric sleeve after adjustment.

What should I do if the high-speed punch fails?
The more common faults are mainly: 1. The inching or interlocking of the high-speed punch cannot be operated due to some reasons, so that the punch cannot be stopped in time; 2. The red light will not be dimmed for the second time, and it will be on all the time; 3. Punch The electric slider cannot be adjusted automatically; 4. The counter cannot work normally, etc.
What is the general difference in the stamping stroke of a high-speed punch?
A 10-ton punch is only a tonnage, which is one of the parameters of a punch. The punch presses with different precisions and different forms produced by different manufacturers are different, and there are many differences. There is no standard. Depending on the design of the punch manufacturer, it is mainly the eccentricity of the drive crankshaft driven by the flywheel. If it is H, then the stroke of the punch is 2H (highest to lowest). Some manufacturers of high-precision high-speed punching presses will also provide according to customer needs, such as stroke 15mm 20mm 25mm 30mm and other specifications, the tonnage can be the same level tonnage.
