Description

Description Cutting press

The invention relates to a cutting press designed for cutting workpieces out of a film, which has a press table and a cutting tool arranged above it so that it can be moved in height.

Cutting presses of the above type are used, for example, to cut soundproofing parts out of bitumen foil, which are then glued to the bodywork of motor vehicles. Such cutting presses usually have several cutting tools next to each other. The bitumen foil is fed to the cutting press as a strip. In many systems, the cut-out punched parts are manually de-screened after cutting and removed from the cutting press. However, cutting presses have also become known in which the cutting tool, with the punched parts held to it by negative pressure, moves to a side position after cutting and deposits the punched parts there. However, this automatic removal of the punched parts reduces the performance of the cutting press because the cutting tool is not available for further cutting work while the punched parts are being moved and deposited.

The invention is based on the problem of designing a cutting press of the type mentioned at the beginning in such a way that an automatic removal of punched parts is possible at the highest possible production speed of the cutting press.

This problem is solved according to the invention in that a storage area for punched parts cut out by the cutting tool is provided on both sides of the press table, that the cutting press has two cutting tools which are rigidly connected to one another at a distance of the storage area from the press table and which are arranged so as to be transversely movable together in such a way that one storage area is covered by a cutting tool when the other cutting tool is located above the press table.

This design means that one cutting tool is always in the working position above the press table and the other cutting tool is always above one of the two shelves. This means that punched parts can be cut and stored at the same time, resulting in a high production speed of the cutting press.

For the invention, it is irrelevant how the punched parts are held on the cutting tools and how they are removed from them. However, the punching tools are designed to be particularly simple if, according to an advantageous development of the invention, the two cutting tools each have a vacuum device for holding the punched parts.

The invention allows for various embodiments. To further illustrate its basic principle, one of them is shown very schematically in the drawing and is described below.

Figure 1 shows a press table 1, over which a steel belt 2 is guided, which is endless, is held taut by two deflection rollers 3, 4 and can be set in a timed circulating movement. Above the belt 2 is a belt-shaped film 5 made of bituminous

Material is shown from which punched parts 6 are punched out using the cutting press.

A storage area 7, 8 is arranged on both sides of the press table 1, from which the punched parts 6 are transported away, for which purpose, for example, conveyor belts 12 can be used. However, it is also possible to place the punched parts 6 directly into a container at the respective storage area 7, 8.

In addition to a cutting tool 9, the cutting press has a further cutting tool 10, which is connected to the cutting tool 9 to form a tool unit 11. This tool unit 11 can be moved together transversely to the press table 1. The distance between the two cutting tools 9, 10 was chosen such that in the right-hand position shown in solid lines, the cutting tool 10 is above the storage area 7, while the cutting tool 9 is aligned above the press table 1 in the working position. If the tool unit 11 is moved to its left-hand position shown in dash-dot lines, the cutting tool 10 is above the press table 1 and the cutting tool 9 is above the storage area 8. The cutting tool 9 can therefore transport freshly cut out punched parts 6 to the storage area 8 and place them there while the cutting stroke takes place. The cutting tool 9 can then transport the punched parts 6 to the right-hand storage area 7 and place them there when moving to the right.
