Abstract

The invention discloses an under-drive punch press which comprises a rack, an upper working platform, a servo drive mechanism, a crankshaft connecting rod mechanism and a toggle rod mechanism, wherein the rack comprises a bottom plate and four upright posts; the upper working platform slides along the upright posts; the servo drive mechanism, the crankshaft connecting rod mechanism and the toggle rod mechanism are arranged at the lower part of the upper working platform; the toggle rod mechanism comprises an upper toggle rod, a lower toggle rod and a toggle shaft; one ends of the upper toggle rod and the lower toggle rod are connected by virtue of the toggle shaft; the servo drive mechanism drives the crankshaft connecting rod mechanism; the other end of the connecting rod of the crankshaft connecting rod mechanism is connected to the toggle shaft of the toggle rod mechanism in a sleeving manner; the other end, namely the upper end, of the upper toggle rod is hung onto a mounting shaft below the upper working platform; the other end, namely the lower end, of the lower toggle rod is fixed on the bottom plate by virtue of a second mounting shaft; and four corners of the upper working platform are arranged on the upright posts in a sleeving manner, and the upper working platform moves up and down along with the upright posts.

Description

1. Technical field [0001] The invention relates to a movement mechanism or a transmission mechanism of a servo press (punch), especially a movement mechanism or a transmission mechanism of a lower transmission punch. 2. Background technology [0002] The servo press is a pressing machine (punch machine) driven by a servo motor. The servo press can precisely control the pressure stroke. At the same time, the press is equipped with a pressing force sensor that can monitor the pressing stroke and pressing force in real time; the servo motor can be directly driven. punch. [0003] Chinese patent publication 101697437A discloses a single servo motor main transmission structure of a CNC turret punching machine, which includes an AC servo motor, a crankshaft, a connecting rod and a slider. The driven crankshaft is connected with the connecting rod, and the connecting rod is connected with the slider to form a planar linkage mechanism. However, the turret punch press is suitable f...
