According to Mr Leong to beball joint informed, the future development direction of domestic CNC machine tools is expected there are some models.
Screw type CNC punch press
Servo machine work is the use of AC servo motor through the screw drive slider, forming the position of the lower dead center position through reading device to provide data to the device to control the position control. Therefore, the mechanical and thermal expanding is elastic deformation will not affect the precision of the products, to adjust the way and the most suitable for the slider movement to extremely small unit control the position of the bottom dead center. So is suitable for high precision high function is cutting servo press forming screw adopts hydraulic motor and the torque control in the form of accumulator, bottom dead center position control can reach micron grade, is to save energy and environmental requirements of the machine.
Crankshaft, servo press
Crankshaft, punch press with AC servo motor combined CNC punch press. This punch is servo motor instead of the original clutch brake on the punch and the flywheel. The press has the slider movement mode can be arbitrary set of the characteristics of the servo press, both ordinary torque characteristics of mechanical press. But it did not reduce work energy in low speed zone.
Double acting forming punch
Double acting forming is a powerful means of no cutting forming. Between the cold forging of block forging is one example, is through the control of multiple punch, concave die action figure and time to achieve the goal of control material plastic flow. The precision of the products and formability can be improved, even can shorten the process.
Double acting forming can be roughly divided into two categories: attaches great importance to punch the versatility of use complex dynamic model of complex dynamic forming; Many kinds of production with easy mold with the use of double acting punch forming. Recently, not only on the forging processing, at the same time in sheet metal forming and forging of diversity and compound forming ability improved at the same time, press not only need to have more action performance, also must possess high versatility.
Block forging press
Shape of star wheel shafts and cross section has been widely used block forging mould and general forging press. The mould structure with occlusion function and coordination function. Other can save the time of mold assembly when piping block forging press can be divided into two classes: these functions are all in the press and the upper and lower cylinder on the punch and coordination mechanism in the mold base on two forms.
Gear forming with a punch press
Helical gear forming with double acting hydraulic press. The punch of sliding driven by, the slider inside 2, table 2, a total of five driver source all share a hydraulic drive. The early stages of the forming and often coping way as inner ring forging forming, convex die insert block of the concave die tooth space, material forming early began to flow from below. In this state, mold core, the center of the material from coarse to fine mold core diameter. At this time there has been a new workpiece diameter of space, can produce new plastic flow, so can increase the pressure material full of tooth apex. Using double acting forming on the material flow control forming of gear can reach JIS3 ~ 4, it is very close to the high added value without cutting forming.
According to Mr Leong to be ball joint informed, CNC punch press main features are:
1.1 easy to use, save the mould cost
CNC turret punch press is the most vitality in pressure processing equipment set machine, electricity, liquid integration products, used in all kinds of sheet metal parts processing, can automatically complete a variety of complex groove and the shallow deep drawing forming, (automatic processing according to the requirement of different size and pitch of the different shape of hole, also can use small punch in step blunt blunt big round hole, square hole, waist type hole and various shapes of curve contour, also can undertake special craft processing, such as blinds, shallow drawing, sink hole, hole flanging, reinforcement, stamping, etc.). Through a simple mold combination, compared with the traditional stamping, save a lot of mold fee, you can use the low cost and short cycle processing and small batch, the diversification of products, has a larger scope and machining ability, to adapt to the change of market and products in a timely manner.
1.2 high precision
CNC punch die cutting of high precision, small cutting burrs, good flatness of workpiece, the follow-up processing capacity, low rejection rate, high forming quality, number of punching processing dimensional accuracy generally can reach 0.1 mm, the size of the product consistency.
1.3 high efficiency, fast delivery time
Processing speed CNC punching machine, general hydraulic equipment stroke rate of up to 500 ~ 600 min, some even as high as 900 min, maximum rate can reach more than 100 mmin positioning. For basic can reach a large size plate processing can be completed and not like the traditional processing, need more than one process, on a lot of different equipment for processing. So as to reduce the intermediate links, reducing the post-treatment process, reduce the mold design, etc., and through a simple mold, CNC integrated processing, greatly saving labor, reduce the cost.
1.4 for punching, forming different processing, etc
CNC punch press in addition to using a simple small punch, and different graphics through rotational mold to processing, can also processing forming (such as blinds, hit convex, flanging), can also processing thread, etc., have a lot of adaptability.
