1. the three factors of the precision punch capacity use the punching machine to carry out the work, the pressure, torque and work ability can never exceed the standard value. In case more than the size of the operation, then the punch will not only damage, but also the danger of personal accidents, we must pay great attention to it.

1.1 pressure ability called "pressurization" refers to the maximum allowable pressure capacity below the position of the capacity of the punching machine to withstand the load in the punch structure. However, considering the difference of material thickness, tensile strength (hardness), the lubrication state of die or the change of wear and so on, the pressure must be given a certain margin. Especially the stamping operation including processing and punching may occur due to penetration of the impact load, pressure punching processing must be limited as follows.

Punching capacity constraints

APA (V)...... less than 70% of the pressure capacity

APA (H)...... less than 60% of the pressure capacity

If the limit is exceeded, the connecting part of the slider and the machine will have the possibility of damage. In addition, the pressure capacity is calculated by the uniformly distributed load on the 60% part of the central part of the die base. So avoid loading the concentrated load with large load or loading the eccentric load off the center (1) in a small area. If you have to work must be in extreme concentrated load or eccentric load condition, please press technology advisory Taiyida (0574-86198848).

1.2 the pressure capacity of the torque capacity punch is changed according to the position of the slider. This change is the "stroke pressure curve". When using this machine, the working load should be less than the added pressure shown in the curve. There is no safety device for torque capacity. The overload safety device or chain mechanism above is a device corresponding to load capacity, and is not directly related to the torque capacity described herein.

1.3 the ability to do work is called "work ability", it is "work energy", that is, the amount of work that is done at each pressure. The energy that the flywheel has, and the energy that can be used for one operation in the output of the main motor is limited. If the punch is used under the condition of exceeding the working power range, the speed will decrease, and finally the main motor will stop because of the heat.

The 1.4 card die usually occurs under the condition of exceeding the torque capacity. When the clutch is not fully integrated, the load may also happen. This phenomenon will have a bad effect on the clutch, so once it is discovered, it should stop immediately before the operation or on the way of operation, and take the necessary measures to prevent it from happening again.

1.5, the eccentric load should be avoided basically. The occurrence of eccentric load will cause the slider and the work table to tilt. Limit the use of the load to ensure the safety of the machine. 1.6 the intermittent stroke number is to make the machine used in the best state, to ensure the service life of the clutch brake. Please use it under the specified intermittent stroke (SPM). If the number of intermittent trips is beyond the regulation, it will cause abnormal wear and tear of the friction disc of the clutch brake, and it is easy to fail.

1.6 intermittent stroke number

In order to make this machine used in the best state and ensure the service life of the clutch brake, please use it under the specified intermittent stroke (SPM). If the number of intermittent trips is beyond the regulation, it will cause abnormal wear and tear of the friction disc of the clutch brake, and it is easy to fail.
