Eccentric sleeve locking mechanism of hot die forging press

Abstract

The invention discloses an eccentric sleeve locking mechanism of a hot die forging press, wherein the eccentric sleeve locking mechanism of the hot die forging press has the advantages of simple structure and fast response. The eccentric sleeve locking mechanism of the hot die forging press comprises an eccentric sleeve, a pull rod and an annular connecting rod, wherein the annular connecting rod is provided with an opening; one end of the pull rod is connected to the opening stressed end of the annular connecting rod and the other end of the pull rod is connected to the opening forcing end of the annular connecting rod, so that the annular connecting rod and the pull rod form a closed annular structure; the eccentric sleeve is sleeved in the closed annular structure formed by the connecting rod and the pull rod; the pull rod is connected to a locking driving device; the locking driving device is a hydraulic and pneumatic power cylinder; one end of the hydraulic and pneumatic power cylinder is fixedly connected to the opening forcing end of the annular connecting rod; the other end of the hydraulic and pneumatic power cylinder acts on the pull rod. A complicated transmission mechanism is unnecessary to be arranged behind the whole hot die forging press, so that the mechanism is greatly simplified and the space behind the hot die forging press is increased; the eccentric sleeve locking mechanism of the hot die forging press not only can be used for manufacturing newly designed hot die forging presses, but also can be used for reforming existing hot die forging presses.

Description

technical field [0001] The invention relates to a locking device, in particular to a locking mechanism of an eccentric sleeve of a hot die forging press. Background technique [0002] At present, because it is considered that a set of mechanisms should be used to adjust the closed height, and to clamp and loosen the connecting rod device of the hot forging press, the closed height adjustment mechanism of the hot forging press in the prior art is as follows: Figure 1 to Figure 3 As shown, during adjustment, the hydraulic motor A drives a pair of reduction gears B, and then the inner hexagon on the gear cooperates with the outer hexagon of the worm shaft C on the connecting rod device to drive the worm shaft C to rotate, and the two sides of the worm shaft C One ball nut D is distributed on each side, the outside of the ball nut D is a worm gear tooth shape, and the inside of one of the ball nuts D is a left-hand thread, and the inside of the other ball nut D is a right-hand t...

Problems solved by technology

However, this mechanism needs to arrange hydraulic motor A, reduction gear pair B, worm shaft C and other mechanisms behind the hot die forging press, and even a supporting platform for hydraulic motor A and reduction gear pair B, resulting in the transmission chain of the entire transmission mechanism Long, not only the equipment is huge, but also affects the layout of other line equipment in the rear, such as the layout of robots; in addition, due to the cumbersome mechanism of the whole mechanism, the response of the transmission process is slow; at the same time, it is not conducive to the maintenance of equipment
