German machine tool manufacturing industry turmoil

German machine tool manufacturing industry turmoil, the Asian market is bullish Machinery manufacturing industry is seen as Germany’s ‘facade’ industry metal hole punch, currently facing the plight of the experts described the ‘twists and turns’. Four months ago, the machinery industry appeared to be still bullish, with a forecast of 4% growth in 2012 and now reporting a zero-growth downside. Germany Machine Tool Manufacturers Association had previously predicted that machinery manufacturing industry ‘thriving’. The global economic recession has caused losses to the machinery manufacturing industry. In 2011, the initial forecast of 14% growth rate Drilling Machine for H beam, and later growth expectations down to 12%, the result is a 1.9% in December to achieve a negative growth. German Machine Tool Manufacturers Association executive director WilfriedSchaefer said: ‘December as the first 25 months since the negative growth steel beam fabrication, resulting in the fourth quarter decline. ‘However, in December 2011, the implementation of the early 1960s, the implementation of order statistics since the new high. In 2011, machine tool production increased by 1/3, a record high growth rate. In the year, the average utilization rate of capacity reached 93.8%.

The backlog was maintained at 9.3 months. As the German machine tool industry production is at a high level, the Association predicts a slowdown in growth this year. However, the association is still optimistic about this year ‘s ‘optimistic.’ The German Machine Tool Manufacturers Association expects the German machine tool industry to grow 5% year-on-year in 2012, on the back of high levels of order reserves, non-delivery orders and capacity utilization. This prediction is based on early macroeconomic indicators. Association forecast Oxford Institute forecast 2012 global economy maintained 2.5% growth rate. Industrial output is expected to show strong growth, on this basis, the main customers of the machine tool industry investment is expected to grow. The key to meeting the challenges of the global recession is to strengthen globalization and break into the Asian market. The challenge, however, lies in the need to address costly and skilled labor shortages. Even in the German machine tool suppliers in the traditional market turmoil when the industry will also be listed as Asia’s ‘huge potential market.’ Stuttgart Chamber of Commerce recent survey shows that machinery manufacturers expect higher than other industries, the industry optimism than pessimism.

The source to eliminate the use of safety and precision presses

Many of the current stamping equipment operating system, electrical control system there are many elements of insecurity, if the continued use of its corresponding skill transformation, perhaps the selection of high security features high precision presses, servo presses and other equipment, from the source to eliminate security risks. Crankshaft is an important structural parts of precision presses induction heating, used to transfer motion and power. In the course of operation, the load is extremely complex, bear infinite impact load, in addition, also by the effect of alternating stress, seriously affecting the fatigue strength of the crankshaft, prone to fatigue failure.

As we all know, precision punching in the production if not timely protection methods, will bring the production risk, affecting the production of power, then there are some precision punching in the production to avoid damage with the method? And with the precision punch to the direction of high-speed development straightening machine, the crankshaft load and operating conditions even more harsh. In the cyclical changes in the load effect, resulting in premature fatigue damage. So it is necessary to analyze the dynamic characteristics of the crankshaft busbar machines.

The work of precision press hydraulic press

Precision Punch Hydraulic Presses In the automotive industry Shearing for Flat Bars, aerospace, aerospace and other categories, the objective of reducing the operational layout quality is to save people looking for energy for a long time, which is also an increasing trend of ancestor manufacturing skills. Hydroforming (hydroforming) is a predecessor manufacturing skill for achieving lightweight layouts.

Hydraulic press molding is also known as ‘internal high pressure molding, the root cause of the root causes of the tube as a blank, the application of ultra-high pressure liquid tube at the same time, both ends of the tube using axial thrust, Billet material plastic deformation, and even the final mold cavity wall joint, hollow shape and precision of the technical part of the hydraulic machine hollow section of the careful layout of the traditional manufacturing process is the first stamping two and a half, and then welded into a group, and hydraulic The hydroforming process has the following immediate benefits: lower quality, less material. Commonly used hydraulic systems Hydraulic pumps and hydraulic motors are modeled as containers, and they have the ability to be used in a wide range of applications. The principle of using the oil to change the volume and oil pressure, the principle point of view, they are different, but there are some different layout. Precision Punch Hydraulic Presses with multi-stage overload screen, oil temperature alarm and oil level alarm screen automatic cover device, such as electrical system using mature PLC control, can ensure silent configuration and operator.

Things pressure cylinder with large flow of liquid valve for the liquid at the same time Deputy fuel tank, you can probably achieve fast filling oil, oil, to promote the return of oil, save money for short periods of time to find and improve the efficiency of forging cnc machining. Reliable cooling circulatory system configuration decoration, you can firmly control the temperature, precision punching machine to ensure reliable operation of the silence straightening machine. Walking is the emergency department of construction machinery transmission system. With the system, the drive system not only requires more power transfer to go, requires a higher equipment efficiency and life expectancy, but also eager to variable speed, differential, output shaft rotation and reverse drive power change, etc. have good skills. So, the focus of communication, how to go to a better sense of fullness of all kinds of construction machinery transmission needs, has been the construction machinery industry is facing problems.

Which Precision punch with the role of servo feeder

Now, you see a lot of factories, skilled unskilled workers or workers a lot, mechanical feeder adjustment will not. Slightly do not pay attention, ranging from the feeder to cut off the arm and legs, while in the work-related injuries. Precision punch with servo feeder is necessary, determined by the characteristics of the servo feeder: for the era of industrial 4.0, the use of closed-loop system control, so that accuracy to ensure that within 0.03mm; stage feeding skills: can enter 6 to 20 groups Different feeding length, each group to provide 999 times the number of stamping to meet the special products of the processing and production; precision punch personalization of the manual mode, allows users to more easily operate and accurately make the material into the mold and positioning; Precision punching machine in the rapid die-changing device steel straightening machine, the clamping mode must be in the next dead point (165 ~ 195 degrees) to do the relaxation action, and the gate-mode track in the punch on the dead point (crank angle 330 ~ 30 degrees) action sheet metal hole punch. The lower clamping mode must wait until the lift mode track down before use, and the punch must be stopped at the bottom dead center, if not reached the same position, the punch can not be continuous operation, with mold and personnel protection. Under the clamping mode to relax after the detection, the die in the die to lift the side.

In the actual precision punch press gantry punch operation, a lot of easy to forging customers will quickly change the effectiveness of the device play most vividly, the key is its practice makes perfect angle closing Machine, the experience was summarized.

This is a matter of caution when installing punch machine

When the punch is installed, it is important to note the following:

1) Before the punching machine is installed, it should be confirmed that the cutting edge of the die is sharp and there is no chipping on the cutting edge of the concave die. If there is collapse or missing angle, please rub the first knife blade.

2) before the mold should be in the upper and lower mold between the pad into a silicon steel sheet, defensive due to handling process bumps knife edge.

3) in the mold before loading the punch, use the whetstone to the bottom and the top of the burr worn off, with a cloth to clean up the waste. If there is burr or rubbish on the upper and lower surfaces of the mold, it will cause the burr tolerance of the die.

4) Punch Adjust the stroke of the slider to the satisfactory position to press the upper mold, make sure that the surface of the mold handle or the mold frame is cleverly fitted on the bottom surface of the slider and the lower mold plate screw is pressed tightly. And then adjust the slide up the punch, remove the center of the silicon steel sheet. Loosen the lower mold plate screw, adjust the slider downward, until the punch into the die 3 ~ 4mm, pressed under the molded plate screws. Punch a new punch punch punch must be into the mold 3 ~ 4mm, otherwise, there must be punch die or concave die burst.

5) take off the slider to the top dead center position, adjust the punch rod back screw, to tighten properly, and then idly a few times to observe the mold and punch the work of the agency is unusual. If there is no abnormal situation, you can start the production.
