Description

Transition turnover mechanism

Technical Field

The utility model belongs to the technical field of automatic retooling, concretely relates to transition tilting mechanism.

Background

In an automatic die change system for stamping production, in order to improve the safety, efficiency and automation degree of die exchange, a die change system is usually provided for each press, and the automatic exchange of dies is performed from a traditional semi-automatic die change system to a full-automatic die change system, for example, by using a die change trolley in the full-automatic die change system. The die changing trolley equipped for the press in the full-automatic die changing system is generally double stations which are a die preparing station and a die taking station respectively. When it is necessary to transport a mold from a mold changing carriage to a mold stocker or from the mold stocker to the mold changing carriage, a traveling crane or a forklift is generally used to transport the mold over a long distance. Due to the characteristics of the structure of the press, the upright column of the press exceeds the press workbench 14, so that a transition buffer platform 13 needs to be added between the die changing trolley 10 and the press workbench 14, and the multi-station movement between the trolley 10 and the press workbench 14 is realized; the existing transition buffer platform is fixed, and the transition buffer platform is fixed on the ground or a press stand column through bolts or welding;

for a die change system transformed by an old production line, more workshop equipment is provided, the space is compact, and sometimes the condition of running and die preparation through a die change trolley is not provided, so that only forklift die preparation can be adopted; when the forklift truck is used for preparing the mold, a larger mold preparation area is required to be occupied due to the structural characteristics of the forklift truck 11 (figure 1); as shown in fig. 2, a tray 15 and a chassis 18 of the conventional fixed die change trolley are connected together by support legs 16 through connecting bolts 19, and traveling wheels 17 are installed below the chassis 18, so that the conventional fixed die change trolley can be matched with the conventional transition buffer platform for use, and die change operation can be well realized; but the pushing and pulling directions of the upper die and the lower die of the forklift are the same as those of a trolley die, the mode is simple and quick, but the occupied space of a die standby area is large, the required width requirement of a die changing channel is large, and the forklift die changing channel is not suitable for a workshop environment with compact equipment layout;

as shown in fig. 3, the tray 15 and the chassis 18 of the rotary die-changing trolley are flexibly connected through a worm gear 20, the tray 15 and the chassis 18 are supported through a roller 21, the tray is driven by a speed reducer during die changing, and is rotated, and the direction of a forklift can be the same as the walking direction of the trolley during die-changing of the forklift, so that the rotary die-changing trolley does not need to occupy extra channel width during die preparation, the space occupied by a die-changing system is greatly reduced, but when the existing transition buffer platform is matched with the rotary die-changing trolley, the transition buffer platform can interfere with the rotating radius of the trolley, and the transition buffer platform cannot be used.
