D-axis high-speed bending mechanism

Abstract

The invention relates to a bending mechanism, in particular to a D-axis high-speed bending mechanism. According to the D-axis high-speed bending mechanism, the speed and the needed pressure can be guaranteed at the same time, the bending effect can be improved, and the service life of a ball screw can be prolonged. According to the technical scheme, the D-axis high-speed bending mechanism is characterized by comprising a 3512 rack, an ES3512 lower workbench, a connecting frame, a fixing frame and the like, wherein the ES3512 lower workbench is arranged on the 3512 rack, the connecting frame is arranged on the side, away from the ES3512 lower workbench, of the upper portion in the 3512 rack, and the fixing frame is arranged on the upper portion in the 3512 rack. According to the invention, the rotation of a heavy-load nut is controlled by using the double motors, a fast-down area and a pressurizing area are separated, the speed can be ensured, the required pressure can be achieved; and when a ball screw moves vertically up and down, an internal auxiliary support part has no circumferential friction and no heating problem, so that the service life of the ball screw is prolonged.

Description

technical field [0001] The invention relates to a bending mechanism, in particular to a D-axis high-speed bending mechanism. Background technique [0002] In the industry, it is often necessary to bend some workpieces. The traditional structure is driven by a high-power motor with a reducer. It needs to realize the two functions of fast down and pressurization at the same time. This will cause the problem that the speed and pressure cannot meet the requirements at the same time. When the speed When it is fast, the pressure cannot meet the required requirements. When the pressure reaches the required speed, the speed is slow. In addition, when the traditional structure is pressurized and driven, it uses the ball screw to rotate to drive the workpiece to pressurize. The steel ball of the rod rubs against the groove of the screw, which causes heat generation and shortens the service life of the ball screw. When bending, the unbalanced bending workpiece often leads to unbalanced...
