An operating method of a push-pull plate device for extending the fixed closing height of a press

Abstract

The invention discloses an operation method of a push-pull plate device for increasing the fixed shut height of a press. When the length of a workpiece is larger than the height between an upper trimming mold and a workpiece groove in an initial position, a handle is pushed to drive a push-pull plate to slide in a T-shaped groove, and after a mold shank and the upper trimming mold deviate from the upper side of the workpiece groove, the workpiece is obliquely sent into the workpiece groove of a lower trimming mold; the handle is pulled to drive the push-pull plate, the mold shank and the upper trimming mold to be restored to the initial position; during trimming, a push-pull plate upper mold, the push-pull plate, the mold shank and the upper trimming mold move synchronously downwards, the upper trimming mold cuts down the edge of the top end of the workpiece inside the workpiece groove, and the cut workpiece directly falls into a slide below from the workpiece groove. The maximum shut height of the press is increased, so that the workpiece enters the lower trimming mold smoothly, the press is applicable to workpieces in various models, the purpose that a small machine can machine large workpieces is achieved, energy consumption is reduced, the business capital is saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of trimming technology of a hot die forging press, in particular to an operation method of a push-pull plate device extending the fixed closing height of the press. Background technique [0002] At present, in the forging production process, due to the limitation of the mechanical closing height of the press, the height of some workpieces that need trimming is higher than the mechanical limit closing height of the press, so that the workpiece cannot enter the trimming lower die, so that the trimming process cannot be completed, resulting in The kinetic energy of the existing presses cannot be fully utilized. Only by purchasing a press with a larger model and a higher closing height can the edge trimming problem be solved, which not only wastes mechanical power, but also greatly increases the company's expenditure funds. [0003] In view of the above-mentioned reasons, now invent a kind of operation method of the push-...
