Abstract

The invention provides a bottom dead center adjusting mechanism for a high-speed press, and relates to the bottom dead center adjusting mechanism for the high-speed press. A pair of connecting rod devices is connected with the top part of a slide block of the press, wherein each connecting rod device comprises a ball connecting rod, a ball cup, an adjusting screw, a worm gear, a worm, a worm driving mechanism, a guide pillar and a guide pillar bearing, wherein the guide pillar bearing is fixedly connected with a body, and is connected with the guide pillar; the guide pillar is provided with a screwed hole towards the direction of the ball connecting rod; the lower part of the adjusting screw is provided with a screw connecting section; the adjusting screw is connected with the screwed hole through the screw connecting section on the lower part of the adjusting screw; the top part of the adjusting screw is provided with a ball cup connecting hole; the ball cup is arranged in the ball cup connecting hole to ensure that the ball connecting rod is connected with the adjusting screw through the ball cup; the worm gear is fixedly connected outside the adjusting screw, and is coaxial with the adjusting screw; and the worm driving mechanism is engaged with the worm gear through the worm. A motor drives the worm gear and the worm, and drives the adjusting screw, the adjusting screw and the guide pillar are in threaded connection, and corresponding rotation of the adjusting screw ensures that the guide pillar can move up and down so as to realize die set height adjustment.

Description

technical field [0001] The invention relates to a press, in particular to a bottom dead center adjustment structure of a high-speed press, and belongs to the technical field of presses. Background technique [0002] During the transition from low speed to high speed, from cold machine to hot machine, the accuracy of the bottom dead point of the slider changes greatly in high-speed presses, which cannot meet the needs of precision stamping. In order to reduce the defective rate, the bottom dead center of the slider must be finely adjusted. [0003] In the existing press technology, the general high-speed press adopts an ordinary disc motor as the driving device for the height adjustment structure of the mold. This structure is low in price and low in cost. The bottom dead center cannot be finely adjusted, which cannot meet the needs of precision stamping. Contents of the invention [0004] The purpose of the present invention is to provide a bottom dead point adjustment m...
