Multi-mold interchangeable indexing station and CNC turret punch die system

Abstract

The invention relates to a die system of a multiple-die interchanged type indexing station and a numerical-control turrent punch press. The die system provided by the invention is provided with the multiple-die interchanged type indexing station; the multiple-die interchanged type indexing station comprises a rotary disc with one indexing die position at least and also comprises a turbine shaft which is arranged above the working position of the rotary disc, is installed in a case body of a turbine worm model rotating device and is connected with a turbine; a striking rod penetrates the hollow turbine shaft and two symmetrical lug bosses are arranged on the bottom of the turbine shaft; a rotary upper die base or a multiple-submodule die holder is arranged in the indexing die position; concave grooves which are precisely matched with the lug bosses are arranged on the top part of the peripheral edge of the rotary upper die base or the multiple-submodule die holder and a locating mechanism is arranged on the bottom of the concave groove at one side; the rotary disc is fixedly provided with a sliding seat which corresponds to each indexing die position and the locating structure is matched with the sliding seat to limit a rotary freedom degree between the rotary upper die base or the multiple-submodule die holder and the rotary disc.

Description

technical field [0001] The proposal relates to a numerically controlled turret punch press, in particular to a multi-mold interchangeable indexing station and a mold system for the numerically controlled turret punch press. Background technique [0002] The CNC turret punch press is the key equipment for sheet metal stamping. In order to improve the efficiency of the equipment, increase the number of stations, and expand the process performance of the machine tool, multi-sub-moulds, rotary mold positions, and double-row mold structure turntables have been fully applied. However, the application of functional molds makes the corresponding control mechanism of CNC turret punch press more and more complicated, and there is a problem of poor interchangeability. [0003] The existing configuration has standard A, B station double-row mold positions, and a mold system with indexing mold positions for simultaneous installation of multi-sub-moulds and standard D-station special...

AI Technical Summary

Problems solved by technology

[0018] 1. Multi-sub-moulds can only use custom-made special upper molds;

[0019] 2. The structure of the mold rotary device is complex and the cost is high; it takes up a lot of space, and the number of other mold positions is bound to be reduced;

[0020] 3. A set of mold rotary device can only control 2 rotary mold positions, and the 2 rotary stations can only be symmetrically distributed in pairs on the axis of the turntable passing through the center of the turntable; limited by the structure, only 4 divisions can be set at most Rotary mold position;

[0021] 4. The index stamping of multi-sub molds cannot be realized;

[0022] The slewing device is installed on the turntable, which increases the weight of the slewing parts and consumes a lot of energy
