Overload protecting electric screw press

Abstract

An overload protecting electric screw press comprises a body, a platform arranged above the body, a special driving motor vertically disposed and installed at the cross beam of the body, a small driving gear directly mounted on the output shaft of the special driving motor, a friction slipping big flywheel driven by the small driving gear through the joggled transmission, a screw fixed at the flywheel through a pin, a nut driven by the screw, a slide block fixed together with the nut, and an external brake shoe brake installed at the platform for braking the flywheel. The invention has simple structure, a few components, short transmission chain, high mechanical strength, easy manufacturing, convenient maintenance, low cost, simple operation, low loss of components, anti-waving by buffering, good coaxiality, stable running, high beating force and deformation energy, high forming accuracy, strong unbalance loading resistance ability, overload protecting property, safety and reliability, long service life, energy saving and wide application range. The electric screw press can be widely used in forging forming industry.

Description

Technical field [0001] The invention relates to an overload protection type electric screw press, which can be widely used in the forging and pressing forming industry. Background technique [0002] Existing electric screw presses are generally not equipped with overload protection drive devices. Only large-scale equipment in foreign countries is equipped with hydraulic overload protection drive devices, but the response is slow, the structure is complicated, the manufacture is difficult, the failure rate is high, and the maintenance is difficult. . Contents of the invention [0003] The purpose of the present invention is to provide a simple structure, few parts, short transmission chain, high mechanical strength, easy manufacture, convenient maintenance, low cost, simple operation, small loss of parts, buffer and anti-swing, good coaxiality, running It is an overload-protected electric screw press that is stable, has high impact force and deformation energy, high formin...
