【CN 201811543525.4 】A New Type of Double-acting Press
[CN 201811543525.4] Title of a new type of double-acting press: Application number of a new type of double-acting press: CN 201811543525.4 Applicant: Yanshan University Application Date: 2018-12-17 Patent Type: Invention Application The present invention discloses A new type of double-acting press belongs to the field of double-acting presses. The present invention unpowerfully hoists the mold clamping slider under the forming slider, and arranges a series of variable magnetic devices inside the mold clamping slider, the variable magnetic unit may be an electromagnetic magnetic pole unit or an electrically controlled permanent magnetic pole unit. The clamping force is generated by the magnetic attraction force generated when the variable magnetic unit in the clamping slider is energized. The invention does not require a complicated mechanical transmission structure or hydraulic circuit to drive the clamping slider, which greatly simplifies the internal structure of the double-acting press; the application of the clamping force of the clamping slider has a large unit area and uniform divisions. Safe and reliable. In the whole working process, the time of charging and demagnetization conversion is very short, and the double-acting press of the present invention can quickly respond to the change of working state; the double-acting press of the present invention is similar to the existing double-acting press in function, and can fully adapt to the work of the existing double-acting press.
