Abstract

The invention discloses a pressure machine capable of driving a balance mechanism. The pressure machine comprises sliding blocks, upper beams, dynamic balance mechanisms; one ends of first transmission shafts of the dynamic balance mechanisms are connected with driving gears, one ends of second transmission shafts are connected with driven gears, the driving gears mesh with the driven gears, the first transmission shafts and the second transmission shafts are symmetrically arranged according to the horizontal center of the sliding blocks, the vertical center of each sliding block is taken as the center, force application bearings are symmetrically arranged on the two sides of the first transmission shafts and the second transmission shafts respectively, the force application bearings are eccentrically arranged, the two sides of each force application bearing are symmetrically provided with support bearings, and the support bearings support the first transmission shafts and the second transmission shafts. First balance blocks take the vertical center of the sliding blocks as the center, the two sides of the first balance blocks are arranged on the first transmission shafts and the second transmission shafts correspondingly, second balance blocks are arranged on the other sides of the first transmission shafts and the second transmission shafts; second balance blocks take the horizontal center of the sliding blocks as the center and are symmetrically arranged, third balance blocks are arranged on the two sides of the driving gears and driven gears as the symmetric center according to the gear thickness, and the first balance blocks, the second balance blocks and the third balance blocks are opposite to the eccentric direction of the force application bearings.

Description

technical field [0001] The invention relates to components of a press, in particular to a dynamic balance mechanism for eliminating the inertia force of the press. Background technique [0002] With the continuous improvement of production enterprises' requirements for the speed of presses, high-speed presses have been widely used, but the press will inevitably generate inertial force when running at high speed. The higher the speed, the greater the inertial force. A well-balanced inertial force will make the dynamic performance of the bottom dead center of the press slider very poor, which will affect the precision of the press and the life of the mold at the slightest, and may damage the press and the mold and make it unusable. Therefore, it is very necessary to balance the inertial force of the high-speed press. Among the dynamic balance mechanisms used in existing presses, the most ideal is the anti-slider mechanism, which can basically balance the inertial force genera...

Problems solved by technology

Among the dynamic balance mechanisms used in existing presses, the most ideal is the anti-slider mechanism, which can basically balance the inertial force generated during the operation of the press. However, due to its complex structure, difficult processing, and troublesome assembly, it must be limited its scope of application

[0003] In addition, in the existing presses, the slider is usually driven by two points of force, and its balance is also poor
