Embodiment

[0030] When starting the whole mechanism, firstly, the motor drives the transmission gear 11, the transmission gear 11 drives the rotating shaft 6, the rotation of the rotating shaft 6 makes the middle large gear 9 rotate, and the rotation of the middle large gear 9 drives the connecting pin 7 to rotate around the center of the central large gear 9 , the connecting pin 7 drives the rocking bar 8 to rotate again, because the other end of the rocking bar 8 is fixedly connected with the transmission shaft 5, so the rocking bar 8 rotates around the transmission shaft 5, and the transmission shaft 5 will rotate with the rotation of the rocking bar 8, and the transmission The rotation of the shaft 5 drives the rotation of the intermediate gear 3, the rotation of the intermediate gear 3 drives the rotation of the left eccentric gear 1 and the right eccentric gear 4, the rotation of the left eccentric gear 1 and the right eccentric gear 4 drives the two connecting rods 2 to move up and ...

Abstract

The invention relates to a double-point eccentric gear type multi-linkage mechanism for a punch press. A rotary shaft connected with a big intermediate gear is installed on one side of the big intermediate gear. A connecting pin which is perpendicular to the end face of the big intermediate gear is installed on the portion, close to an outer ring, of the interior of the big intermediate gear. The middle of the connecting pin is connected with one end of a rocker. The other end of the rocker is connected with a transmission shaft which is installed in the middle eccentric position of the interior of the big intermediate gear. One end of the transmission shaft vertically penetrates through the middle of the front end face of the big intermediate gear, and an intermediate gear is installed at the end. A left eccentric gear and a right eccentric gear which are engaged with the intermediate gear are symmetrically installed on the two sides of the intermediate gear. Connecting rods are installed on the front end face of the left eccentric gear and the front end face of the right eccentric gear. Guide columns are installed at the lower ends of the connecting rods. The double-point eccentric gear type multi-linkage mechanism for the punch press has the characteristics that the structure is simple, the production cost is low, the punching speed during punching can be effectively decreased, rapid returning is guaranteed, and the punching efficiency of the punch press is guaranteed.

Description

technical field [0001] The invention relates to the technical field of a multi-link mechanism for a punching machine, in particular to a double-point eccentric gear multi-link mechanism for a punching machine. Background technique [0002] In the general punching machine transmission system, the slider crank mechanism is used, and the slider is faster in the stamping process, which causes some defects in some products during molding. In order to solve this problem, low-speed stamping is adopted during the stamping process, which can ensure good forming and further protect the service life of the mold. In order to realize the characteristics of low-speed punching and fast return, it is necessary to develop a double-point eccentric gear multi-link punching machine. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a double-point eccentric gear multi-linkage mechanism for a punching machine, which has a simple struct...
