Technical Field

The invention relates to the technical field of punching machines, in particular to a punching closing height adjusting device.

Background

In the high-precision stamping process, the fluctuation of the stamping height is easily caused by the abrasion of the bearing and the change of stress, the fluctuation is called as height deviation, and in the actual working condition, the height deviation needs to be compensated to meet the requirement of high-precision stamping. The maximum pressure of a common crimping machine is more than ton, which causes that the upper dead center on the press needs to bear a large stamping acting force, however, under the actual working condition, the situation of dead pressure or die seizure is sometimes encountered, and the acting force is even stronger under the situation. In order to achieve the purpose of height adjustment, adjustment of common screws or lead screws cannot or barely bear, the special conditions of punching cannot be adapted, the crimping height cannot be adjusted under the condition of pressure application, and damage to devices and workpieces is easily caused.

According to the problems, the invention provides a stamping closing height adjusting device, which adopts a mechanical and electric control mode to compensate height deviation, meets the requirement of high-precision stamping, has small bearing stress, is suitable for long-term work, and prolongs the maintenance time and the service life of a press.

disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a stamping closing height adjusting device.

In order to solve the technical problems, the invention provides the following technical scheme:

The invention provides a stamping closing height adjusting device which comprises an adjusting slide block and an upper stop point slide block, wherein a lead screw mounting hole is formed in the adjusting slide block, one end of a ball screw penetrates through the lead screw mounting hole to be connected with a lead screw nut, the other end of the ball screw is fixedly connected with a servo motor, an adjusting assembly is arranged at the joint of the ball screw and the servo motor, and the adjusting assembly is fixedly arranged on a press frame; the connecting part of the upper dead point sliding block and the adjusting sliding block is provided with a first oblique angle, the inner side of the first oblique angle is provided with a limiting hole, a limiting stop block penetrates through the limiting hole to fixedly install the upper dead point sliding block on the inner wall of the press frame, and one end, far away from the oblique angle, of the upper dead point sliding block is connected with the air cylinder through a force applying mechanism.

As a preferred technical scheme of the invention, a second bevel angle is arranged at the joint of the adjusting slide block and the upper stop slide block.

As a preferable technical scheme of the invention, the inclination angle of the first bevel is consistent with that of the second bevel and is 5 degrees.

As a preferable technical scheme of the invention, the inclination angles of the second bevel angle arranged on the adjusting slide block and the first bevel angle arranged on the upper stop slide block are opposite, one bevel angle is inclined from top to bottom, and the other bevel angle is inclined from bottom to top.

The invention has the following beneficial effects: the adjusting slide block drives the ball screw to rotate through the servo motor so as to achieve the purpose of sliding the adjusting slide block up and down, and the adjusting slide block slides up and down so that the second oblique angle arranged on the adjusting slide block moves along the first oblique angle arranged on the upper dead point slide block in the same step, thereby achieving the purpose of driving the upper dead point slide block to move left and right; the invention adopts a mechanical and electric control mode to compensate the abrasion deviation and the elastic deformation deviation of the press, meets the requirement of high-precision stamping, enables the press to adapt to the stamping of workpieces with different heights by adjusting the closing height, and expands the multi-purpose function of one machine.
