Esko Pertti Tyynelä, Ilmarintie 10, 80330 Reijola, Finland-Finland (FI) (7 * 0 Esko Tyynelä (5U) Mechanism for attaching and detaching a tool package for a press, punch or similar device - Mechanism for inserting and cutting the tool package in the press, Punches A device

The invention relates to a tool package fastening and detaching mechanism according to the preamble of claim 1.

In individual press tools, each tool usually has its own frame, sometimes the same frame may be used for several tool packages, in which case the packages are positioned with loss guides and fastened with hexagon socket screws through holes drilled through the tool package. A locking ring can also be placed in the recess of the screw, in which case the fastening screw also acts as a detachable member from the positioning pins.

One of the disadvantages is that the fastening screws must always be fully opened, as they are always included in the tool package, so several are needed for each tool cooker. Switching the toolkit is also slow and clumsy.

It is an object of the invention to provide a tool package attachment and detachment mechanism in which the clamp has a single base body to which minor tool packs are attached and detached for each job without removing the tool body.

The mechanism is suitable, for example, for attaching and detaching a tool package in accordance with Finnish patent application No. 771384.

The features of the invention appear from claim 1. The release and fastening mechanism thus constructed works reliably and is in accordance with the object of the invention.

In a preferred embodiment, the fastening and detaching mechanism of the tool package is formed by grooved screws arranged in the tool body so that the tool package can be pushed laterally into the grooves formed in the fastening screws.

This has the advantage that the mounting package does not have to be drilled with mounting holes and the mounting screws do not have to be completely removed, only loosened, and only one mounting screw per frame is required.

The screws also carry the package to the pre-positioning support, making the package easy and quick to replace.

The invention will now be described in more detail with reference to the accompanying drawing, in which - Fig. 1 shows a cross-section of the fastening and detaching mechanism of the tool package according to the invention - Fig. 2 shows a section A-A of the tool according to Fig. 1,

In the drawing, 1a means the upper body and 1 h the lower body, 2 interchangeable tool packages and 3 tool package attachment and detachment mechanisms.

The tool package 2 is positioned on the tool body by means of cylindrical pins 4a and 4b or the like.

The groove side 5a in the tool package attachment and release mechanisms 3 performs the attachment of the tool package 2. The groove side 5b performs the removal of the tool package 2, from the precise cylindrical guides 4a and 4b.

The groove base 6 gives the tool packs 2 a pre-guide laterally when performing a work * tool change.

The invention is not limited to the embodiment shown, but several variations of the invention are conceivable within the scope of the appended claims.

Claims (2)

59349 - 4 - A mechanism for attaching and detaching a tool package of a press, die or similar device, comprising a tool mounting body (1a, 1b) to be attached to a machine, a tool (2) and fastening and detaching members (3) movable in the working direction in the mounting body (1a, 1b). by means of abutment surfaces (5a, 5b) alternatively arranged against said tool in said direction, the tool (2) can be pressed against or detached from the fastening body by displacing its pin guides (4a, 4b), characterized in that said abutment surfaces (5a, 5b) form a fastening - from the opposite surfaces of the groove (6) formed on the side of the release and release members, between which the tool (2) can be placed from the side of the implement. Fastening and detaching mechanism according to claim 1, characterized in that the groove (6) in the fastening and detaching members (3) pre-positions the tool package 2 with respect to the pin guides (4a, 4b).
