[CN 202110701026.9] implosion type overload protection device and method for press
[CN 202110701026.9] Title of Implosive Overload Protection Device and Method for Press: Application Number of Implosive Overload Protection Device and Method for Press: CN 202110701026.9 Applicant: Zhejiang Strom Technology Co., Ltd. Application Date: 2021-6-22 Patent Type: Invention Application for Implosive Overload Protection Device for Press, Including Ball Head for Press, Ball Head Cooperatively Connected with Ball Bowl, Said Ball Bowl Cooperatively Connected with Oil Cylinder; A pressure chamber is arranged between the ball bowl and the oil cylinder. The pressure chamber is connected with a pressure oil circuit and an overload overflow oil circuit. The pressure oil circuit and the overload overflow oil circuit are two different oil circuits; the pressure oil circuit is connected with Overload pump. The invention adopts a pressure chamber between the ball bowl and the oil cylinder, the pressure chamber is connected with a pressure oil circuit and an overload overflow oil circuit, and the pressure oil circuit and the overload overflow oil circuit are two different oil circuits. By setting the pressure and overload overflow oil circuit separately, the press will stop instantaneously when overload occurs. Compared with the traditional pressure and pressure relief oil circuit, it is more sensitive and safe to respond to the same oil circuit structure.
