Abstract

The invention discloses a miniature table press of a ball screw driven by an AC servo direct drive motor. The miniature table press comprises an AC servo motor, wherein the AC servo motor drives a driving wheel to rotate through a planet wheel speed reducer, a belt transmits the torque of the driving wheel to a driven wheel and a nut, threads are arranged at the outside of the upper end of a nut sleeve to be matched with the nut, the nut sleeve is installed on a ball screw, the nut sleeve rotates in situ and drives the ball screw to rotate, the other end of the ball screw is connected with a ball screw pressing plate, the ball screw pressing plate is limited by a guide post to rotate and only perform linear motion, an upper mould is connected with the ball screw, the rotation motion of the nut sleeve is converted into linear motion through the ball screw pressing plate, the ball screw and the upper mould linearly reciprocate according to the direction of the guide post to stamp a plate to be formed, the plate is formed in a lower mould, a grating ruler monitors the position of the upper mould, and the miniature table press disclosed by the invention can realize a plurality of kinds of pressing curves, improve the pin forming quality of electronic chips and reduce the waste product rate.

Description

technical field [0001] The invention relates to the field of pressure processing equipment for materials, in particular to a small desktop press machine with an AC servo direct drive motor driving a ball screw. Background technique [0002] The pressure processing of materials includes a mechanical processing method in which metal and non-metal materials are separated, formed, extruded, and rolled under the constraint of a mold and the action of forging pressure. For example, stamping of sheet metal in the automotive industry, metal sheet stamping of household appliances, stamping of military chip products, etc. Especially with the advent of the information age and the rapid development of the electronics industry, various chips emerge in endlessly. Generally, the pins of electronic chips sold on the market are basically pre-formed and can be used immediately after purchase. However, in the field of military industry, most electronic chips are not processed, and need to go ...
