The invention discloses an efficient method for controlling the ejection of a cam of a mechanical press. The cross section of the cam of the mechanical press includes a plurality of arcs with different diameters and the same center, and the mechanical press is provided with a connection end, the speed of the connecting end relative to the cam surface of the mechanical press is calculated. Compared with the uniform speed operation of the cam in the prior art, the ejection effect of the efficient mechanical press cam ejection control method of the present invention is higher, and the ejection accuracy is effectively guaranteed according to the diameters and speeds of different parts of the cam. Experimental verification obtains good technical effect, meanwhile, in the control method of the present invention, the speed formula of the connecting end relative to the cam surface of the mechanical press is further optimized, and a correction item is added according to the radian of the arc, so that the result of the speed formula is more accurate. excellent.
Description
technical field [0001] The invention relates to an efficient control method for cam ejection of a mechanical press. Background technique [0002] In the prior art, the cam structure of the mechanical press has a great influence on the precision of the mechanical press. At the same time, the applicant found that the speed of the cam when it works in different parts also has a greater impact on the precision of the mechanical press. big impact. Therefore, how to find a suitable mechanical press cam structure and find a corresponding control method is the object of the present invention. [0003] Therefore, there is a need for a new and efficient cam ejection control method for mechanical presses to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a high-efficiency cam ejection control method for a mechanical press with high ejection precision, aiming at the shortcomings of the high-efficiency cam ejection contro...
