Precautions for selecting CNC turret punch press
We know that the CNC turret punch is a processing program compiled by programming software (or manually). The servo feeding mechanism sends the sheet to the position to be processed. At the same time, the mold selection system selects the corresponding mold in the mold library. The hydraulic power system presses The program carries out stamping and automatically completes the machining of the workpiece. Therefore, we should choose the CNC turret punch press from three aspects: the driving method, the thickness of the turret, and the number of mold positions of the turret.
1. Driving method of CNC turret punch
There are three driving modes of CNC turret punch press: hydraulic, mechanical and servo-mechanical. The use cost of the mechanical drive method is relatively low, and the maintenance is simple, but the disadvantage is that the noise is larger and the mold release is astringent.
The hydraulic type has a relatively high cost of use, but has low noise and smooth mold release. In addition, the operating environment temperature of hydraulic equipment has requirements, which cannot be lower than -5 degrees in winter and cannot be higher than 70 degrees in summer. Therefore, cooling and heating equipment should be installed to ensure the normal operating temperature of the equipment. The all-electric servo drive is a new technology in recent years. The punching speed is higher than the above two types, but it is mostly used for punching thin plates. Therefore, three drive modes can be selected.
2. The thickness of the turret
Because the thickness of the turret determines the amount of deformation of the turret, the thin turret has a much higher probability of deformation than the thick turret. Once the turret is deformed, it will directly cause gnawing, which cannot be repaired, and only the turret can be replaced. Therefore, The use of thick turret will make the mold have good neutrality, high guiding accuracy, strong anti-eccentric load capacity, and greatly improve the service life of the mold. Of course, it also depends on the material to be processed. Generally, it refers to punching workpieces of the same or several hole types on plates above 4mm and below 15mm. It is suitable to choose automatic thick plate CNC turret punch.
3. The number of modules of the turret
According to the number of hole types, the equipment of how many stations is selected. Most of the CNC punching machines on the market currently have 32 stations, but in many cases, 32 stations are still wasteful for most users. In fact, there are 24 stations and 20 and 18 stations. Practical, there are also 16-station ones, but since there is no D-station, it is not very convenient to use blinds because there is no D-station. The 18-station and above do not have this problem, and they all bring at least one D-station. In addition, many users are engaged in communication and high and low voltage. The amount of this piece is usually relatively large. It is generally recommended that the cost of one 32-station is not as good as two 18- or 24-station, and the efficiency of the two is better. Much faster than one.
