Lifting mechanism of special machine tool for large punching die maintenance

Abstract

The invention discloses a lifting mechanism of a special machine tool for large punching die maintenance, and belongs to the technical field of machines. The lifting mechanism of the special machine tool for large punching die maintenance comprises a support and further comprises a rising and falling mechanism arranged on the support, wherein an overturning plate is clamped by the rising and falling mechanism and is in threaded connection with an upper die, the rising and falling mechanism is connected with a synchronous running mechanism for adjusting synchronous movement of the two sides ofthe rising and falling mechanism, and one side of the rising and falling mechanism is further provided with an overturning mechanism for rotating the overturning plate. The support comprises a horizontally-arranged bottom plate, a horizontal plate is correspondingly arranged above the bottom plate and is parallel to the bottom plate, and supporting rods vertically downwards extending are arrangedat the four corners of the bottom face of the horizontal plate and connected with the top face of the bottom plate. According to the lifting mechanism, synchronous running of two sliding plates is guaranteed through the synchronous running mechanism, precision is improved, an inner cavity of the upper die can be upwards overturned through the overturning mechanism, and maintenance is convenient.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a lifting mechanism of a special machine tool for maintenance of large stamping dies. Background technique [0002] Large-scale stamping dies are mostly used for stamping automobile panels, and the upper die can weigh up to 40 tons. Due to the high stamping strength, the die often needs to be rested during debugging and use to maintain its accuracy. Die manufacturers and users often use Install the mold on a special press for maintenance, because the press is a special stamping operation equipment, the price and the cost of use are expensive, and when the mold is installed on the pressure slider, the press slider has no flip function, and the inner cavity of the upper mold cannot Turn it upside down, making maintenance inconvenient. Contents of the invention [0003] 1. technical problem to be solved [0004] Aiming at the problem in the prior art that the main...
