Precision high-speed punch circuit and mechanical principle
The circuit component of the precision high speed punch contains the Self locking model head button. Under this button, all control circuits are not electrostatic, and the main motor is overloaded with heat relay. The mechanical principle is to convert the circular motion into a straight line motion and contribute to the main electric motor.
Precision high speed punching circuit element
The purpose of each control electrical component:
1. SB1 — Self locking model head button. Under this button, all control circuits are not electrostatic.
2. SB2 -main motor stop button,
3. SB3-Main Motor Start button can be stamped only after the main motor starts.
4. SA – choose from foot switch stamping or two person press the button to stamp.
5. SQ-foot switch, use it when operating.
6. SB4/SB5-two hands press buttons, use it when the two persons are operated.
7. TV-lighting transformer BZ-50VA
8. KM -Main motor starts the contactor.
9. KA-Intermediate relay connected to stamped electromagnet.
10. CT-Electromagnet.
11. KH -Main motor overload heat relay.
6. Re- Reworked punch star-stop electrical control principle with F8
12. QF1 — Power total switch, short circuit protection
13. QF2 -Control circuit switch and short circuit protection.
14. QF3 -Lighting switch and short circuit protection.
Principles of precision high speed punching machinery
The mechanical principle of precision high speed punching is to convert the circular motion into a linear movement, which is contributed by the main electric motor to drive the flywheel to drive gears, crankshafts or eccentric gears, connecting rod, etc, to achieve a straight line motion of the slider, from the main electric motor to the connecting movement.
There must be a transition point for circular motion and straight movement between the connecting rods and sliders. There are roughly two types of institutions in their design, one is the ball type, and the other is a pin type (cylindrical type).Through this mechanism to convert the circular motion into a straight line motion of the slider. The punch press applies pressure to the material, causing it to plastically deform, and obtain the required shape and accuracy. Therefore, it is necessary to cooperate with a set of molds (upper mold and lower molds) to place the material in between, and the machine applies pressure to deform it. The reaction force caused by the force exerted on the material during processing is absorbed by the punch machine body.
