Domestic punch in the international press industry occupies an important position

China is the world’s largest consumer of 63 tons of punch and importers in 2016, 63 tons of punching machine tool industry in China completed more than 7,400 billion yuan, up 32.5% from the same period last year, the total industrial output value. But the scale does not mean the quality of continuous growth of the domestic CNC 63 tons of “punch” to meet the “quality” of the bottleneck in the high-end market share, the overall brand image to promote the many issues such as the industry also paid close attention.

In the high-end market competition

From the 63-ton press industry in China’s development status, the production of 63 tons of CNC punch, especially in the high-grade numerical control 63 tons of punch seriously underestimated the proportion of the gap compared with the developed countries

According to China’s 63 tons of stamping machine recently held in Nanjing Tools Industry Association 630,000 tons of the 7th China CNC punch press exhibition at home and abroad well-known exhibitors amounted to more than 150, more than doubled over the same period last year. This shows that brought about 630,000 tons of international and domestic huge market Punch enterprises to enter the phenomenon has been shown to accelerate the trend.

In 2016, the metal processing 63 tons of 40.6%, the growth rate of imports of punch, much higher than the domestic metal processing 63 tons of punch production growth rate of 26%. Imports from Germany and Japan accounted for two-thirds of the total, higher average metal processing unit price of imports of 63 tons of punch increased by 33.2%. By the high inlet pressure, the domestic metal processing 63 tons of 66.1% punch domestic market share, down 0.8% over the previous year.

On the one hand, the domestic market demand structure to accelerate this upgrade, the user in the high-end market, a significant increase in demand, and on the other hand reflects the high-end products out of the country, in technology, industrialization, to adapt to the market, the overall service still can not meet the market Of the demand.

From 63 tons of punch industry in China’s development status, the production of 63 tons of CNC punch press, 63 tons of high-grade CNC cut into a serious underestimate, especially the proportion. January to August 2016, 63 tons of punching industry in China’s CNC production rate of 30.94% on average, an increase of 2.9% from the same period last year, but with some developed countries, there are 63 tons 70% punch NC , Compared to the gap is obvious.

In this regard, 63 tons of punching machine tool industry in China Kurumoto executive vice president, said that compared with the international advanced level, China 63 processing accuracy, reliability, efficiency, automation, intelligent and environmentally friendly tons of punch there is still a great difference. At present, enterprises should seize the opportunity, market demand, as soon as possible, high – end product market adjustment product structure.

How to Avoid Punching machine Safety Accident

Punch machine is a high result of a simple, sluggish processing of construction, the press when the security of the production of a wide range of users concerned about the issue, how effective proof of the outbreak of security is to do a good job security system enslavement hub. Punch manufacturers to remind how to guard against the occurrence of punch safety incidents.

1, the mold promotion prevention program

Protective measures against the mold include the creation of protective plates (hoods) and presses around the mold to improve the mold construction. Such as contraction of mold damage area, increase the safety of space; set the mechanical discharge installation, not affect the strength of the mold and the demand for product quality, will always be a variety of manual feeding single process mold to improve safety.
2, the use of hand-safe objects

The use of hand tools may avoid accidents caused by improper mold planning and unexpected damage to the press facilities. More common security workers are: flexible clamp, special clamp, magnetic sucker, tweezers, pliers, hooks and so on.

3, the installation of security guards

In the stamping equipment and molds to set up security devices or picking up the strength of the small, simple and clever use of hand tools, but also the current conditions under the punch press workshop effective measures to stamping the safety of homework. Such as the use of hand tools, mold protective cover, mechanical access device, double button switch, mechanical handle, push hands and hand device, photoelectric active care devices. Stamping equipment, more protective devices, according to the structure is divided into mechanical, push-button, photoelectric, feeling and so on.

Punch industry development trend

If you need to form or block forged link presses, choose a high position. If you want to choose a punch press, press the button to select the punch press. In order to achieve non-cutting shape, the punch function is getting higher and higher. Stamping machinery is the development trend of high precision, high rigidity, the right movement characteristics, intelligent, multi-directional movement, and even the direction of environmental protection. And numerical control system of the development trend of CNC punch presses, according to the need to arbitrarily set the processing method of sliding mode speed movement. 1, Screw CNC punch press research report High-speed CNC hydraulic turret punch research report Hydraulic tower punch research report CNC hydraulic punch press research report Hydraulic CNC turret punch research report More mechanical industry analysis Servo motor using AC servo motor The bottom dead center of the slider is driven by the screw, and the position can be controlled by the data supplied from the position reading means. Therefore, mechanical thermal expansion and elastic deformation does not affect the accuracy of the product, adjust the slider movement of the most suitable and very small units to control the bottom of the dead zone position. Therefore, the punch in the high-precision, high-performance non-cutting forming screw servo presses using torque control of hydraulic motors and energy storage technology applications, the bottom dead position control can reach micron-level, energy saving and environmental requirements of the aircraft.

2, crankshaft servo punch crank and CNC punch press AC servo motor combination. This 0 is a servo motor to replace the clutch brake and flywheel original punch. Of the punch press with a servo can be set by the movement of the slider features, and general mechanical punch torque characteristics. But the energy in the low-speed region is not reduced.

3, the formation of complex dynamic punch is a powerful tool for cutting. Punch in cold forging closed-die forging is an example, by a number of punch, the role of die and time control of the material to achieve the plastic control. The accuracy and formability of the product can be improved, and even the number of working steps can be reduced. Complex dynamic formation can be roughly divided into the use of complex dynamic molding compound forming is divided into two categories: pay attention to the punch in general; multi-species production mold installation easy to use complex dynamic punch forming demolition. Recently in forging, but also sheet metal forming and forging composite forming and the increase in the capacity of the diversification, requiring not only punch with multi-action performance, must have a high versatility. Mechanical Punch 1 The general trend of high-rigidity punch press, the original general-purpose machine punch at the same time the pursuit of high-performance high-precision, high performance, developed a gantry press; link drive mechanism and near the bottom dead and the rod Punch effect is very slow. The connecting rod presses the crankshaft between the driving gear and the two eccentric connecting rods. When the driving gear rotates, the crankshaft will move at a constant speed due to the change of the link angle. Connecting rod and connecting rod linkage mechanism, the compression part of the connection point is small, the overall gap is small. The connecting rod mechanism can realize the high torque capability and the higher punch forming position than the toggle mechanism. Vertical Linkage Punch Drive is the link between the normal toggle mechanism and the vertical link and the fulcrum is a link that allows the machining link to be directly connected to the slider to maintain the vertical state and to be vertically loaded through the vertical connecting rods. 2, the general mechanical punching machine As the baroclinic body in the slider, the slider by the lateral force of the larger, therefore, the transmission method has a higher precision than the ordinary drive, more suitable for high-precision machining. 5 mm above the location of the general toggle-type slider slide lateral force accounted for about 10%, forming force and vertical rod-type punch does not exceed 1%. The punching machine applicable to the middle and lower die of the high, medium and low processing requirements. The drive mode and the drive are almost zero for the side force slider, but the stroke can be done much more than in the higher position, and the bottom dead center does not change much at all. The linkage ensures that the connecting rod maintains a substantially vertical state during operation. Punch The vertical connecting rod punch is used for machining, but in the complex shape of the machining, the first use is to be processed in the latter part of the complex manner. The mobile device can be used in a variety of different types, such as a suction cup or a jaw-type three-dimensional servo multi-station conveyer. There are two basic characteristics of the domestic manufacturers to produce punch presses, which are rigid, including longitudinal stiffness, sliders, hog and elastic elongated workbench, sliders and lateral displacements under lateral stiffness and eccentric load. The movement of the slider, including straightness, verticality, parallelism, the accuracy of the product has a great impact. The accuracy of the product not only with the press, it is material, related mold, lubrication and so on. Considerations. The punch press takes into account the punching factors, the thickness direction accuracy of the product is related to the longitudinal stiffness, with the deviation, bending or parallel to the lateral stiffness characteristics and the motion curve. Therefore, these characteristics are improved, the accuracy of the product is improved, the life of the die is prolonged, and the production stability is improved. According to the forming method, forming speed, production, etc., it is necessary to consider the characteristics of punch press. On the basis of the driving mechanism, the most widely used mechanical punching machine is: the punching process crankshaft punch press and the bottom dead center near the slowest switch punching and the high sliding speed bottom dead center position is slow and have high torque link Type punch capacity.
