Increased demand for high-end CNC punch press market

According to market changes, the future direction of domestic CNC machine tools is expected to have the following models.

The screw type CNC punch servo work machine uses an AC servo motor to drive the slider through the screw. The position of the lower dead point in the forming can be controlled by the position reading device to provide data to the position control device. Therefore, the thermal expansion and elastic deformation of the machine will not affect the accuracy of the product, adjust the most suitable way of slider movement and control the position of the dead point in an extremely small unit. Therefore, the high-precision high-performance cutting-free forming screw servo press adopts a hydraulic motor and an accumulator for torque control. The bottom dead point position control can reach micron level, which is an energy-saving and environmentally friendly machine. .

Crankshaft Servo Press Crank Press Combined with AC Servo Motor CNC Punch. This type of press uses a servo motor to replace the clutch brake and flywheel on the original punch. This kind of punch has the characteristics of the servo punch which can be arbitrarily set in the slider movement mode, and also has the torque characteristics of the ordinary mechanical punch. However, its working energy will not decrease in the low speed area.

The double action forming punch press is a powerful tool for cutting without forming. Forging forging in cold forging is an example of controlling the plastic flow of a material by controlling the motion and time diagram of multiple punches and dies. The precision and formability of the product can be improved and even the number of processes can be shortened.

Re-formation can roughly be divided into two major categories: emphasis on the versatility of the punch press using double-acting molds; multiple-product molds can be assembled and disassembled easily using the punch press. Recently, not only in the forging process, but also in the diversification of the forming of the sheet metal and the forging and the improvement of the capability of the composite forming, the punching machine is required not only to have a multi-action performance but also to have a high versatility.

The use of closed forging dies and universal forging presses has been widely used in the forming of occlusal forging punch star wheels and Phillips couplings. Its mold structure has occlusive function and coordination function. Other occlusion forging presses that can save the piping time during mold assembly can be divided into two categories: these functions are all in the press and the upper and lower cylinders are on the punch and the coordinating mechanism is on the mold base in two forms.

Gear forming presses Helical gears for the formation of a complex hydraulic press. There are a total of 5 hydraulic drive units for slide press drive, 2 sliders and 2 worktables. The initial stage of forming is the same as that of the inner ring of the atmospheric pressure ram type. The male mold is inserted into the concave tooth space in the occlusion and the material flows from the bottom to the initial shape. In this state, the core rises and the diameter of the core in the center of the material narrows. At this time, there is a new space in the inner diameter portion of the workpiece, and a new plastic flow can be generated, so that the increased pressure material can fill the toothed tip portion. The gears that control the formation of the material flow through the compounding process can reach JIS Class 3~4, which is very close to the high value-added non-cutting forming.
