Problems solved by technology

[0003] The throttling hydraulic valve is a kind of hydraulic valve, because of the characteristics of "it can basically keep the movement speed of the actuator with little change in load pressure and low requirement for uniformity of movement" after adjusting the area of ​​the orifice. Used in aero-engines, the filter nozzle is an important part for filtering impurities in the throttling hydraulic valve. The quality of the filter is directly related to the energy supply of the entire hydraulic control system, so the filter nozzle is very important from its material selection to the entire processing process. Important, directly related to the flight safety of the aircraft, it is very important, so it has high requirements for its filtration, and denser filter holes need to be set on it, but because the product size itself is small, dense holes are punched on it It has brought many difficulties to the production. The current existing technology not only has complicated procedures and slow processing efficiency, but also because the filter holes are too dense, it is prone to uneven punching and slag generated during the punching process. Chips block other holes, or even the holes are not opened, which will affect the filtering effect. If the holes are uneven, it will affect the strength of the entire filter nozzle. Therefore, the existing processing technology needs to be improved.
