Abstract

The invention discloses a booster for a servo press, which comprises a frame, four moving branched chains of the same structure, a sliding platform, a guide rod and two links. The four same moving branched chains are symmetrically arranged, wherein two branched chains are jointly connected to one link to form a left mechanism of a symmetric mechanism, the other two branched chains are jointly connected to the other link to form a right mechanism of the symmetric mechanism, each branched chain comprises three connecting rods, one connecting rod is connected to the guide rod, one connecting rod is connected to the sliding platform, and the rest connecting rod is connected to the frame. Four-point output of the four branched chains on the sliding platform can be obtained by means of input of the guide rod. Besides, the booster has a great boosting effect at some positions of the sliding platform, namely a great output force can be obtained at the position of the sliding platform by applying a small input force to the guide rod. The booster is simple in structure, low in manufacturing cost and capable of effectively solving the problem that an existing servo press cannot realize four-point output through single-point input.

Description

technical field

[0001] The invention relates to a forging machinery technology, in particular to a booster device of a servo press with a booster function. Background technique

[0002] Presses are widely used forging equipment in the field of metal forming processing. There are many varieties and quantities, among which mechanical presses are the most widely used. The development of modern manufacturing technology requires that the press can not only operate at high speed, high precision and large load, but also have greater flexibility, and can change the output motion law quickly and conveniently. The traditional mechanical press has single motion characteristics and poor process applicability. In recent years, with the gradual development of AC servo motor-driven forming equipment technology, various AC servo-driven presses with adjustable slider motion curves have appeared, which has greatly improved the working performance and process applicability of the press, and t...
