Slide block synchronizing mechanism for four cylinder driving hydraulic machine

Abstract

The invention discloses a slide block synchronizing mechanism for a four cylinder driving hydraulic press. The slide block synchronizing mechanism includes slide blocks (1) and machine body columns (2). Gears (3) are arranged on four corners of the slide blocks (1), four machine body columns (2) are provided with racks (4) matching with the four gears to form a gear-rack synchronizing mechanism. According to the slide block synchronizing mechanism for the four cylinder driving hydraulic press, the structure is compact and reasonable, synchro errors among four cylinders can be eliminated effectively so that the slide blocks can operates stably, synchro errors among components can be eliminated again by adjusting positional relations when synchro errors occur after the mechanism operates for a relatively long time. Besides, the service life of the mechanism is relatively long and relatively high synchro accuracy is guaranteed.

Description

Technical field [0001] The invention belongs to the field of hydraulic press structures, and particularly relates to a four-cylinder-driven hydraulic press slide block synchronization mechanism. Background technique [0002] As an important mechanical equipment, hydraulic presses are widely used in forming process fields such as forging and stamping. Commonly used hydraulic presses are generally driven by single or double cylinders, but when such hydraulic presses press some large parts, the product cannot be evenly pressurized due to the cylinder arrangement or even pressure relief occurs, so the performance of the pressed products meets the standard Waiting phenomenon. If four-cylinder drive can effectively avoid these shortcomings, but four-cylinder drive will also bring a problem, because the synchronization between the four cylinders cannot be ensured, which leads to the failure of synchronized and coordinated movement between the driving points of the slider. The operatio...

AI Technical Summary

Problems solved by technology

Commonly used hydraulic presses are generally driven by single or double cylinders. However, when this type of hydraulic press presses some large parts, because the arrangement of the oil cylinders cannot make the product evenly pressurized or even release the pressure, the performance of the pressed product will meet the standard. Isomorphism

If the four-cylinder drive can effectively avoid these shortcomings, but the four-cylinder drive will also bring about a problem, because the synchronization between the four cylinders cannot be ensured, resulting in unsynchronized and coordinated movements between the drive points of the slider, resulting in The slider runs unstable, which affects the service life of the equipment
