heavy punch more and more drill hole in angle iron

punching at home and abroad between the enterprises of tobacco Today, the world’s heavy-duty precision punch manufacturing industry has undergone significant changes in the competitive landscape, mainly in the manufacturer of a high degree of concentration, the level of product technology gradually narrowing the gap, the user needs outstanding personality. Over the years, foreign heavy presses to enter the Chinese market mainly in Germany, Italy-based. By the impact of the world market downturn in punch, the German heavy-duty punch manufacturing industry gradually declining, some well-known enterprises were merged or closed down. However, the Italian heavy-duty enterprises in support of government subsidies, the rapid development in recent years, a great alternative to Germany’s potential. Spain’s heavy-duty punch manufacturing industry development is also impressive, no doubt will pose a certain threat to domestic enterprises iron worker tools. Therefore, in the future market competition, China’s heavy punching machine enterprises are mainly faced with international competitors mainly from Germany, Italy and Spain.

Domestic heavy punch manufacturing enterprises manufacturing capacity is very strong, but large but not fine, the main reason is the processing equipment behind, NC rate is very low, especially the lack of high-precision level of processing equipment.

The Specific Meaning and Influence of Accuracy of High Speed

High-speed punch accuracy of the specific meaning and impact? Many customers in the procurement of presses, will ask what is the meaning of precision standards in the end, the specific test is what the project is not the actual punching accuracy of the production? In response to this problem, we here to answer our customers in detail: In the high-speed press punching production, the punch accuracy is very important. Punch precision directly affects the accuracy of stamping products, die life. The accuracy of the press is divided into the static accuracy of the punch when it is not loaded and the dynamic accuracy of the load (punching). High-speed press punching is very important in the actual production of dynamic accuracy, due to the use of presses, the actual load changes in volume is very large, so specifications are technically difficult, it has not yet integrated development, the status quo is static accuracy to represent the precision punch. Punch is the use of a group of molds, processing operations need to set the correct relationship between the mold movement.

Punch the correct relationship between the movement process is the punch accuracy, accuracy is mainly reflected in the punch: First, parallelism, two, vertical, three, the total gap. The relationship between the mold movement is not correct, in addition to reducing product accuracy and shorten the life of the mold, the mold will also lead to easy assembly, can not use precision molds, and will produce intense vibration noise. Co-ordination of the static accuracy of the punch test items are as follows: 1. Punch table above the slider with the following straightness 2. Parallelism between the underside of the slider and the top of the table 3. The vertical movement of the slider and the top of the table 4. Mold handle hole and the straight angle below the slider 5 punching machine. Above and below the joint part of the total gap? Impact of punching accuracy on stamping parts In modern stamping operations, if only high-precision, long life of the mold, without high-precision punch and punching materials with high-quality, is unable to achieve high-precision stamping process. Punch precision and rigidity of the life of a great impact on the mold, the same mold in a different punch on the punch to show different performance and service life. Such as in the general accuracy of the punch on the use of tens of thousands of times that chipping, and in the high-precision precision punch on more than 1 million times have chipping phenomenon.

Dynamic accuracy and punch parts of the rigidity are directly related to the rigidity of a good punch accuracy is relatively high dynamic. If the punch load boring equipment, structure and other compression structure will be deformed. So the static accuracy will deteriorate, you can say that dynamic accuracy is the real precision. Punch precision and accuracy of the product, die life has a very close relationship between. The dynamic accuracy is directly related to the rigidity of each part of the press, and the dynamic accuracy of the punch with good rigidity is relatively high. Actual stamping process is very important in the dynamic accuracy, because the specifications have technical difficulties, it has not yet integrated development, the status quo is the static precision to represent the accuracy of punch. ?? IPM companies adhere to the ‘scientific management custom metal fabrication, and carefully developed; quality and efficient, compliance about re-letter’ quality, and continuously improve the quality of all staff awareness and quality of work.

High-speed punches and precision punch of the integration

High-performance automatic precision punching technology in the punching industry has always occupied a special position drilling milling machine. Unless the matching mold with the same level of excellent performance, even the best performance of automatic high-speed punch is also impossible to obtain the highest performance. High-speed precision punching the same reason, if the automatic punch can not achieve the desired performance, even the world’s best die can not play its due role. In making investment decisions, no one stamping company will be compromised in the quality of the product, and asked to achieve the highest level of productivity. In the investment decision-making, the need to better understand the development trend, not short-sighted, do not see the best symbiotic environment, and will unduly focus on short-term investment cost savings. Most European manufacturers, especially the German metal stamping industry very much appreciate this belief. Easy to forging press) the success of the company’s sales is a good proof, especially in the Yangtze River Delta region and its surrounding high degree of specialization in the development of mold manufacturing enterprises better illustrate this point. About this project Previously, the customer had to punch the parts specified in the processing contract on its four presses, working seven days a week for 24 hours a day to meet the production requirements of 350 million parts per year. The plant was still using non-forgeable presses) and Punch produced by non-Stepper companies. In the case of overtime hole punching machine, the plant’s existing production equipment stamping speed of 400 times / min, and the use of Bruderer and Stepper companies combined production equipment, the ramping speed increased to 800 times / min hydraulic press manufacturers. As a result of the use of two sets of equipment, so the production efficiency of its parts of not less than 1600 pieces / min. This is the effect of the rationalization effect.

However, for the high-speed machine tool system standards, the company’s deputy general manager of Mr. Wang clearly pointed out: ‘Speed ​​does not mean everything, from the high standards of equipment and mold requirements to start.No doubt, the real situation should be : Only consider the whole process of high – speed stamping, continuous production of three shifts, and a high degree of reliability, in order to explain whether it is a perfect or special solution. Just look at the easy punching press.) The company’s punching machines, with its high rigidity design and rigorous level of accuracy, can understand why the system has such a high performance. The success here is based on the expertise of Taiwan and Japan. Where all the high-quality mold parts are designed and manufactured in-house. The mold product line can be divided into three main categories: starting from the PROTO series of molds (for the production of similar prototype tensile die, short delivery time), to the MODULAR 1st generation modular mold (for small and medium-sized product line and complete sets Product line) to modular F1 SUPERTEC technology (for best-in-class mass production).

Super Material In addition to the use of special ceramic materials, the term ‘super-material’ as used herein refers to a hard metal material specially developed for Stepper having a very fine grain structure with a particle size of only 0.3 m ( Typically a hard metal particle size of 0.7 to 1 μm). Precisely because of the fine grain size of the hard metal, it provides the basis for the manufacture of molds with a stable blade, so that their products have a long service life and, of course, many other necessary factors. These factors include internally developed super-surface technology, which enables the product to be machined to have a surface roughness of Ra0.01μm with a tolerance of 1μm. Another example is the development of spraying facilities, the coating surface hardness up to 5000HV. F1 SUPERTEC features high precision and high productivity. This innovative project is a good example of the argument that the ‘Made in China’ molds are still profitable and can benefit the world over. In fact, the company also offers a variety of automatic punch debugging services, Mr. Zhao is not contradictory, he said: ‘For us, on the one hand set up a stamping shop is very important, we can use these presses Testing, using our stamping dies, or developing new manufacturing processes. On the other hand, we also provide services to customers who have no experience or expertise in metal stamping and solve production bottlenecks for those in need . ‘
