Die changing trolley of press machine and die changing method

Abstract

The invention discloses a die changing trolley of a press machine in the field of press machines. The die changing trolley comprises a trolley body; the bottom of the trolley body is provided with wheels, the trolley body is provided with a driving mechanism, a pair of die carrier guide rails and a die carrier pushing-pulling mechanism, the die carrier pushing-pulling mechanism comprises a pushing-pulling motor, the output end of the pushing-pulling motor is provided with a belt pulley I, and the belt pulley I is connected with a belt pulley II in a driving way through a belt to which a sliding pothook is connected; the lower part of a die carrier is provided with double rows of die carrier rollers, the trolley body is provided with a die carrier limiting mechanism comprising a base plate, the base plate is provided with a slide wheel axle which is rotatably connected with a side wheel, and the upper end of the side wheel axle is provided with a pressing plate; and the trolley body is provided with a die carrier lifting mechanism in parallel, the die carrier lifting mechanism comprises a roller carrier controlled by a hydraulic cylinder to lift, horizontal rollers are horizontally arranged on the roller carrier, and roller shafts of the horizontal rollers are parallel to the die carrier guide rails. By using the die changing trolley, the die carrier of the press machine can be rapidly changed, the die changing time can be shortened, and the die changing efficiency can be increased.

Description

Technical field [0001] The invention belongs to the field of presses, and particularly relates to a die changing cart and a die changing method for a press. Background technique [0002] With the development of presses in the direction of multi-variety, high-speed, automation and flexibility, how to quickly replace molds has become a bottleneck restricting the efficient production of presses. Especially for large-tonnage presses, it is more difficult to replace and transport large mold bases. Large, long downtime for mold change, the lifting equipment must be used to move the mold base out of the press to change the mold, which increases the labor intensity of the operator, prolongs the downtime of mold change, and seriously affects the production efficiency of the press. Summary of the invention [0003] One of the objectives of the present invention is to provide a press die change trolley, which can quickly replace the press die frame, shorten the time of die change, reduce the...
