Problems solved by technology

However, the motor, crank, connecting rod and other parts of the utility model are all located in the middle and upper part of the punching machine, with a high center of gravity and unbalanced mass distribution, which makes the body of the punching machine very heavy and requires high installation requirements.
At the same time, the lateral force in the horizontal direction that the slider bears in the process of reciprocating up and down is relatively large, and it changes periodically. The lateral force will cause friction between the slider and the slider guide seat, resulting in meaningless friction losses and power consumption, while wear significantly reduces the service life of the slider and slider guide

Abstract

The invention discloses a dual-elbow-rod punch, which comprises a punch. The dual-elbow-rod punch comprises a driving gears and two driving mechanisms, wherein each driving mechanism consists of a driven gear, a connecting rod and a dual-elbow-rod mechanism; one end of the connecting rod is eccentrically hinged on the driven gear, and the other end of the connecting rod is hinged with an upper elbow rod of the dual-elbow-rod mechanism; the two driven gears of the two driving mechanisms are symmetrically and externally meshed at two sides of the driving gear; and hinge points between the connecting rods in the two driving mechanisms and the driven gear are centrally symmetrical relative to a rotating center of the driving gear. The dual-elbow-rod mechanism drives the punch to move, horizontal resultant force stressed on the punch is zero, only force in a vertical direction is stressed, the punch is guaranteed to reciprocate stably in the vertical direction, no friction is formed between the punch and a punch guide seat; and the punch has low energy loss and long service life. A motor is arranged below the punch, the center of gravity of the punch is lowered, whole mass distribution of the punch is even, and the punch is conveniently mounted and fixed.

Description

technical field [0001] The invention relates to a mechanical stamping equipment, in particular to a double toggle punch press. Background technique [0002] Punch presses are important equipment for sheet metal stamping. At present, punches with better performance mostly use the combination of crank linkage mechanism and toggle mechanism to drive the reciprocating movement of the punch. For example, the Chinese utility model patent CN2686800Y discloses a toggle-type main transmission device for CNC turret punch presses, which mainly includes servo motors. , crank, connecting rod one, toggle one, toggle guide seat, connecting rod two, toggle two, toggle three, slider and slider guide seat, the toggle one is mounted on the toggle guide seat, sliding The block is installed on the guide seat of the slider, the servo motor is connected with the connecting rod one through the crank and the joint, the other end of the connecting rod one is connected with the toggle one through the...
