The design principle of the punch press is to convert circular motion into linear motion. The main motor drives the flywheel, and the clutch drives the gear, crankshaft (or eccentric gear), connecting rod, etc. to achieve the linear motion of the slider. The motion from the main motor to the connecting rod is circular motion. There are two kinds of mechanisms in the design, one is ball type, the other is pin type (cylindrical type). Through this mechanism, the circular motion is converted into the linear motion of the slider. Gantry punch is made of cast iron alloy with high rigidity. The slider is designed with long guide road and equipped with slider balancing device, which makes the operation stable. All hard to wear components are electronic timing automatic lubrication system, if the lack of lubricating oil, the punch will stop automatically. Simple control system, slider operation and stop accuracy. It can be used with any automatic production demand to improve the production rate and reduce the cost. Gantry punch is widely used in the stamping processing of small parts such as electronics, communication, computer, household appliances, auto parts, motor stator and rotor.

When using punch, it can not be connected with impact, which will have corresponding impact on the equipment. Therefore, in order to help us use it, we can only move and not impact. So what are the main reasons for the impact? Here, I will give you a detailed analysis:

Stamping steel sheet (copper sheet) by punch is smelted → impurities are caused → hardness is uneven → punch wear is caused → rough edge is caused:

1、 The improvement method is adopted: timing, setting, barrel inspection, trend analysis, and die change.

2、 Strengthen die design: find out the center point (including the setting of upper main column) by computational mechanics, improve the shape of punch, improve material, heat treatment method, improve structure, edge improvement, reduce wear, etc.

3、 Improve the purchasing materials: find a stable steel mill, analyze the material composition, find out the steel materials which are not easy to wear.

4、 Analyze other reasons: punch speed, whether there are other causes of wear and eliminate.

5、 Machine review: maintenance of machining accuracy, calculation of load force, material requirements of all parts of the mold, setting of processing life and inspection and maintenance after stamping, mold management, tool microscope maintenance and correction, operation, training and assessment of quality inspectors, etc.

6、 Other processing methods: reduce the tension, reduce dust, reduce debris, etc.

7、 Instrument free inspection method: the tool microscope is used to analyze the material of punch metallography, saw blade, scratch and corrosion.

The friction coefficient of each mechanism of gantry punch is low, usually less than 0.03, low friction, prohibited process and good filtration system, which makes the gantry punch machine with good machining precision. In the process of the operation of the common punch, it is inevitable that the machine tool processing will be caused by vibration deviation due to its own structure, friction and anti shock. However, because the standard reverse dynamic balance device is used in the gantry punch, it can realize the smooth operation of the punch under the gantry operation, improve the machining accuracy of the parts and the service life of the processing parts of the punch itself. Generally speaking, the continuous punching of pneumatic punch can be divided into two possibilities, one is that the punch clutch slips and wet clutch appears more. Another is the failure of electrical or PLC program. You can replace accessories or modify programs to resolve them, or you can add protection.
