AI Technical Summary

Problems solved by technology

Problems can actually arise when uneven forces act on the components of a fineblanking press
This uneven force is especially likely to occur in progressive tooling operations
Uneven forces can lead to tilting of the press ram, which negatively affects the guidance of the press ram on the press frame
This can also lead to tool damage, press guide wear or leakage due to extreme wear of the press ram hydraulic drive
All of these negatively affect the life and performance of the fineblanking presses and the quality of the parts produced

Abstract

The invention pertains to a press ram for a fine blanking press, comprising a ram plate section for carrying a fine blanking tool, and comprising guide sections for guiding ram movement relative to a press frame of the fine blanking press during a fine blanking process, arranged on two opposite sides of the ram plate section, wherein the guide sections extend to a vertically higher level than the upper side of the ram plate section on both opposite sides of the ram plate section. The invention also pertains to a fine blanking press.

Description

technical field [0001] The invention relates to a press ram for a fine-blanking press, comprising a ram plate section for carrying a fine-blanking tool, and comprising means for guiding the ram during the fine-blanking process relative to the fine-blanking press A guide section for the movement of the press frame, the guide section being arranged on two opposite sides of the ram plate section. The invention also relates to a fine blanking press. Background technique [0002] Fineblanking presses allow, for example, blanking of parts from sheet metal with high quality and flexibility in part design. A fineblanking press generally comprises a press head and a table unit, such as a workbench, arranged opposite the press head. Fineblanking tools are arranged on the press head. A fineblanking tool may comprise, for example, one or more than one platen or ejector, directly connected by means of transfer pins to the pressure pads of the press head or table, or to any other pad i...
