[CN 201610296820.9] Operation method of a push-pull plate device for extending the fixed closing height of a press Title: Operation method of a push-pull plate device for extending the fixed closing height of a press Application number: CN 201610296820.9 Applicant: Luoyang Guanzhuo Heavy Industry Equipment Co., Ltd. Application date: 2016-4-28 Patent type: Invention application for an operation method of a push-pull plate device for extending the fixed closing height of a press, when the length of the workpiece is higher than the height between the upper cutting die and the workpiece groove at the initial position, push the handle to drive the push-pull plate to slide in the T-shaped groove. After the die handle and the upper cutting die deviate from the right above the workpiece groove, the workpiece is fed into the workpiece groove of the lower cutting die along the inclined direction. Pull the handle to drive the push-pull plate, the die handle and the upper cutting die to return to the initial position, the push-pull plate upper die, the push-pull plate, the die handle and the trimming upper die move down synchronously, so that the trimming upper die cuts off the top edge of the workpiece in the workpiece groove. The cut-off workpiece directly falls into the lower slide from the workpiece groove, prolonging the maximum closing height of the press, so that the workpiece smoothly enters the trimming lower die. It is suitable for various types of workpieces, achieving the goal that small machines can do big work, saving energy consumption and enterprise funds, improved production efficiency.
