Embodiment Construction

[0036] For a better understanding of the present invention, the various embodiments of the equipment of the present invention represented in the accompanying drawings will be described below with the punching action as a working step. In this case, a metal strip guided in linear translation on a support plate is chosen for illustration, this strip being the so-called flat part. But this does not mean that the invention is limited to the machining of this type of flat parts.

[0037] The apparatus of the first embodiment of the invention is used for punching metal strips fed horizontally into the apparatus, such as figure 1 -3 shown. A support 2 for a cylinder pivot mount 3 is fastened to the machine frame body 1 of the punching machine. Here, the pneumatic cylinder 4 selected as the driver is installed on the frame body 1 through the cylinder pivot mount 3, and the piston rod 5 is installed so as to move linearly in the pneumatic cylinder 4, and the piston rod 5 serves as th...

Abstract

The present invention provides a kind of equipment that is used for stamping, embossing and / or forming flat part, and it comprises a support plate and a tool seat plate, is connected between driver and tool seat plate a long rotating lever, can make The tool seat plate is moved from the dead center position where the tool punch does not engage the support plate to a position just before the machining position without building up pressure, and then continues to move the tool seat plate a short distance to reach Processing position, during which a high pressure is generated between the tool seat plate and the metal strip, and then the further drive of the driver causes the tool seat plate to move in the opposite direction to the stop position, during which no pressure is established, and the long turning lever One end of it is connected to one end of a short turning lever through a elbow lever pivot shaft, and the other end of the short turning lever is connected to the tool seat plate through a bending lever mounting part, and at the other end of the long turning lever, the driver Mounted so that the drive is axially outward of the pivot axis.

Description

technical field [0001] The present invention relates to an apparatus for stamping, embossing and / or forming flat parts, comprising a base body with a worktable and a support plate for supporting flat parts and a tool seat, A tool punch can be mounted on the tool seat plate and the tool seat plate can be moved by a drive towards the support plate to a processing station for the work process, so that the tool punch engages and disengages the support plate. Background technique [0002] Such equipment is used for stamping or forming flat semi-manufactured products such as plates, strips and various blanks in continuous processing. These sheets, strips or various blanks, known as flat parts, can be of various materials, such as cardboard, lined cardboard material, multi-layer material or metal sheet. [0003] Known devices similar to those proposed in the opening part of this patent specification are provided with a direct hydraulic or pneumatic drive, such devices having a cyl...
