Slow wire walking, also called low-speed wire walking, uses continuously moving fine metal wires (called electrode wires, generally copper wires) as electrodes to pulse spark discharge on the workpiece to produce a high temperature of over 6000 degrees, ablate metal, and cut A kind of CNC machining machine tool into a workpiece. The principle of slow-moving wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge.
There is an essential difference between the process characteristics of fine blanking and ordinary blanking. Normal blanking controls the tearing of the sheet during the blanking process, while fine blanking tries its best to suppress the tearing of the sheet during the blanking. The fine blanking is always kept as one body before the parts are separated from the sheet material, and the metal sheet is always in the plastic deformation process during the fine blanking process.
On November 8-10, 2021, China Forging Press Association is scheduled to hold the 14th China Fine Blanking Technology Seminar and China Forging Press Association Fine Blanking Committee 2021 Committee Meeting on November 8-10, 2021 in Wuhan, Hubei Province. Changes in the automobile market, continuous changes in vehicle models, and vigorous development of new energy vehicles have had an impact on the fine blanking industry. As a manufacturing industry closely related to automobiles, where does the fine blanking industry go? How to transform is worthy of people's thinking. In order to better cope with the impact of the automobile environment, this conference will arrange wonderful industry reports, technical lectures, seminars, experience sharing, etc. , Arranged visits to outstanding companies after the meeting to discuss the development of the industry together. All fine-blanking parts manufacturers, suppliers and personnel from related enterprises are welcome to actively sign up to participate. The organizer of the conference has just released a new conference schedule, and dozens of high-quality reports will be presented soon!
The greater role of the car sensor housing is a physical one. As an electronic packaging housing, it can improve the protection level of the sensor and prevent external water, oil, dust, debris, etc. from affecting the performance and service life of the sensor. At the same time, it also has the function of anti-shock, which prevents damage to the sensor when the sensor is slightly impacted by external force. The impact-proof effect of the metal shell is better than that of the plastic shell, and it also has a good anti-interference effect to prevent external electromagnetic interference from affecting the measurement.
