Problems solved by technology
[0004] ①. The ball screw is a slender shaft with poor rigidity, and there is vibration during operation. When running at high speed, the vibration is more severe, which seriously affects the transmission accuracy. Especially the X-axis travel is long, and the required ball screw is also Longer, lower rigidity, and lower rotational speed, which seriously restricts the increase of feeding speed
[0005] ②. The Y-axis ball screw nut is directly connected to the beam, and the driving force of the Y-axis increases the vibration of the beam, causing the screw and the beam to resonate, so that the feeding speed cannot be increased.
In order to meet this demand, the feeding mechanism of the CNC turret punch press needs to have high speed and high dynamics. The original feeding mechanism can no longer meet the new market requirements for the CNC turret punch press.

Embodiment Construction
[0020] Such as Figure 1-4 As shown, it is a high-speed feeding mechanism, which includes a feeding table 11 set on the frame. The feeding table 11 is provided with a Y-axis driving mechanism. In the shaft drive mechanism, the length direction of the beam 4 is perpendicular to the Y axis and parallel to the X axis.
[0021] The structure of the Y-axis drive mechanism: it includes two Y-axis linear guide rails 12 arranged in parallel on the front and rear sides of the feeding workbench 11. The Y-axis linear guide rails 12 are equipped with a Y-axis slider 9 connected to the Y-axis slider 9. The connecting plate 8; the bottom of the beam 4 is connected and fixed with the two connecting plates 8 through the reinforcing plate 7, and the front and rear sides of the reinforcing plate 7 are provided with reinforcing ribs 18 connected with the beam 4; The ball screw corresponding to the linear guide rail 12, the screw seat 14 of the ball screw is fixed to the feeding workbench 11, th...

The invention relates to a high-speed feeding mechanism belonging to the field of press machines, and comprising a feeding workbench arranged on a stand, wherein a Y-axis driving mechanism is arranged on the feeding workbench; the upper side of the Y-axis driving mechanism is connected with a beam; the beam is connected with an X-axis driving mechanism; the length direction of the beam is vertical to the Y axis and parallel to the X axis; the Y-axis driving mechanism is a driving mechanism with double servo motors and double lead screws; and the X-axis driving mechanism is a gear rack transmission mechanism. The high-speed feeding mechanism can reduce the vibration of the whole device and ensure smooth running of the device. Matched with a weight reduction design of the beam, the whole feeding mechanism is light in weight, thus ensuring high-speed, accurate and smooth feeding. The high-speed feeding mechanism provided by the invention can feed materials at high speed smoothly, obviously improves the work efficiency, and can be used on a numerical control turret punch press.
Description
technical field [0001] The invention relates to a press, in particular to a feeding mechanism on a numerical control turret punch press. Background technique [0002] The feeding axis of the CNC turret punch press includes the X axis in the left and right movement direction of the carriage and the Y axis in the front and back movement direction of the beam; its structure mainly includes three parts: the X axis transmission mechanism, the Y axis transmission mechanism and the beam. At present, the two feeding axes of the CNC turret punch press generally adopt a drive structure directly connected by a single servo motor and a single ball screw; among them, the X axis: the ball screw is installed on the beam, and the beam is also equipped with a linear guide rail, and the carriage is installed On the linear guide rail slider, guided by the linear guide rail, the carriage is rigidly connected with the ball screw nut through a connecting piece; the servo motor rotates positively ...
