Abstract

The invention provides an automatic travel regulating device for a pressing machine. A pair of main motors is connected with two sides of a frame symmetrically; an eccentric shaft sleeve mechanism is mounted in the frame; the shaft ends on two sides of the eccentric shaft sleeve mechanism are connected to and inserted into the main motors through splines; a link mechanism is mounted at the middle eccentric part of the eccentric shaft sleeve mechanism through a bearing sleeve; a sliding block mechanism is positioned under the link mechanism and is connected with the link mechanism through dowel pins; a guide mechanism is mounted on the frame in a position under the link mechanism; the sliding block mechanism slides up and down in the guide mechanism; an eccentric sleeve regulating mechanism and a rotary key regulating mechanism are mounted on the frame; the working parts of the eccentric sleeve regulating mechanism and the rotary key regulating mechanism are arranged in the grooves of the frame, which are positioned under support necks on two sides of the eccentric shaft sleeve mechanism. The automatic travel regulating device can be widely applied to modern pressing machines and has the outstanding advantages of simple structure, low cost, small occupied area, quickness in regulation, large transmission moment, high degree of automation and the like.

Description

technical field [0001] The invention belongs to the technical field of presses in mechanical forming equipment, and in particular relates to an automatic stroke adjustment device for presses. Background technique [0002] Most traditional presses adopt a design with a fixed stroke, and a few presses with adjustable strokes also have the disadvantages of time-consuming and laborious adjustment and complicated adjustment mechanisms. It is difficult to meet the requirements of various stamping and forging parts on the market for modern presses. Multi-purpose requirements for one machine. [0003] The eccentric synthesis adjustment method is the most commonly used stroke adjustment method at present. Its principle is: the traditional crank is designed as two parts of the eccentric shaft and the eccentric sleeve (or the outer eccentric sleeve and the inner eccentric sleeve) that can rotate with each other, and the eccentric sleeve (the outer eccentric sleeve) ) of eccentricity e...
