Breaking-out system for automatic punching machines

摘要

Technical problem of the invention = technical object and aim Tools for removing break-out parts are usually screwed in manually during machine standstill. In order to reduce the machine standstill and/or tooling periods, a completely fitted-out material plate is to be inserted into the machine. The means are to be provided by which the pins are not permitted to yield to the pressure from beneath, produced by the material, in order thus to make it possible for the waste to be broken out of a material sheet. Solution of the problem or of the technical object According to the judgement of the user, holes of individual diameters are drilled into a material plate (1) by means of a laser or a drilling machine. Pins of different shapes and dimensions (3) are plugged, clamped or screwed into said holes and serve to remove break-out parts. The fitted-out material plate (1) is inserted into the tool frame (4) from above. <IMAGE>
