(1) First use the Φ0.20mm cutting wire to process the template hole to the required size, and the inner corner part to R0.15mm.
(2) Demagnetization, shutdown.
(3) Replace Φ0.10mm filaments. Move the wire cutting wire to the unused position. If the conveyor belt is used in all three positions and the feeding of the filaments is not effective, replace the new conveyor belt.
(4) Re-centering. Point-type support enables the precise positioning of the lower deflection point of the cutting wire to precisely guide the cutting wire. When the diameter of the cutting wire is Φ0.20mm, find the center at point b, when the diameter of the cutting wire is Φ0.10mm, find the center at point a, |ab|=|bo|-|ao|=0.1 〖KF ( )2〖KF〗〗-0.05 〖KF()2〗 〖KF〗=0.0707mm.
Therefore, the coordinate value of the center of the φ0.10mm replaced filament should be different from the original central coordinate value by approximately 0.0707mm.
(5) Modify the corner radius of the graphics, reprogramming, avoiding the contour of other holes, and trim the corner radius of the hole to R0.07mm.
(6) Machining sequence of multi-holes die, fixed plate, and discharge plate Multi-hole dies, fixed plates, and unloading plates take into account the influence of residual stress and processing heat during the processing of each type of hole. Deformation, so in the actual production of the use of the same order of the hole processing method to ensure the consistency of the position of the hole shape deformation, thus ensuring the die, the fixed plate, and the plate hole of the coaxiality of the discharge plate.
The walking wire cutting machine has high processing precision and strong functions, but the processing cost is high. To make full use of the role of the machine tool and create a good economic benefit, it is necessary to perform reasonable processing technology analysis and technical performance analysis on the workpiece to fully understand the structure of the machine tool. Performance and mastery of machine tool operation skills, the rational selection of water parameters and electrical parameters, reducing the broken wire in the process of processing, in practice continue to sum up lessons learned, so as to maximize the potential of machine tools, improve production efficiency.
Solenoid valve is an industrial equipment controlled by electromagnetism. It is an automatic basic component used to control fluid. It belongs to actuator. Pneumatic solenoid valve is one of them. It blocks or leaks different oil drain holes by controlling the movement of valve body. The oil inlet hole is normally open, and hydraulic oil will enter different oil drain pipes, Then the oil pressure of the pneumatic solenoid valve pushes the piston of the oil cylinder. In this way, the mechanical movement of the whole solenoid valve is controlled by controlling the current of the electromagnet of the pneumatic solenoid valve.
Characteristic
It can work normally under vacuum, negative pressure and zero pressure, but its diameter is generally less than 25 mm.
It can also operate under zero pressure difference, vacuum and high pressure, but it has high power and must be installed horizontally.
The upper limit of fluid pressure range is high, which can be installed arbitrarily (need to be customized), but the condition of fluid pressure difference must be met.
Principle editing voice
There is a closed cavity in the pneumatic solenoid valve, and there are through holes in different positions. Each hole of the pneumatic solenoid valve leads to different gas pipes. There is a valve in the middle of the cavity and two electromagnets on both sides. The valve body will be attracted to which side when the magnet coil is electrified;
The pneumatic solenoid valve blocks or leaks different exhaust holes by controlling the movement of the valve body, and the air inlet is normally open. High pressure gas will enter different exhaust pipes, and then push the piston of the cylinder through the air pressure of the pneumatic solenoid valve. In this way, the mechanical movement of the whole solenoid valve is controlled by controlling the current of the electromagnet of the pneumatic solenoid valve.
Operation principle of pneumatic solenoid valve
We said the pneumatic solenoid valve working position (solenoid valve on or off), in fact, refers to the pneumatic solenoid valve spool position.
