Abstract
The utility model relates to a speed increasing mechanism of a hydraulic piercing press, which comprises a piercing needle seat, a piercing needle and a motion rod, wherein a male slide seat is fixed on the motion rod and the male slide seat and the female slide seat make sliding contact with each other. The end part of the motion rod can be rotationally connected to one end with a rocker arm, the rocker arm can be rotationally connected to a rocker arm rotation seat by a second rotary shaft, the other end of the rocker arm is rotationally connected with a hydraulic oil cylinder by a first rotary shaft, wherein the length of the rocker arm segment between the first rotary shaft and the second rotary shaft is the first length, and the length of the rotation junction between the second rotary shaft to the motion rod and the rocker arm is the second length and the second length is larger than the first length. Therefore, a minor stroke of the hydraulic oil cylinder can result in a larger stroke of the motion rod, the translatory velocity of the motion rod can be quickened and workpieces can be pierced rapidly.
Description
Technical field
The utility model relates to a kind of hydraulic piercing press.
Background technology
In the prior art, hydraulic piercing press is used for workpiece is carried out punching, comprise towards needle stand, be fixed in and describedly on needle stand, dash pin, described motion bar on needle stand is fixed in one end, be fixed with public slide on the described motion bar, described public slide and the contact slidably mutually of female slide, usually adopt pneumatic air cylinder driven motion bar, but the impulsive force that pneumatic cylinder produces is less, under some occasions, can't carry out punching to workpiece, although and hydraulic cylinder has bigger pressure, but the speed that hydraulic cylinder is advanced is too slow, causes the efficient of punching to reduce.
Summary of the invention
The object of the present invention is to provide a kind of speed increasing mechanism of fireballing hydraulic piercing press.
The technical solution of the utility model is: a kind of speed increasing mechanism of hydraulic piercing press, comprise towards needle stand, be fixed in and describedly on needle stand, dash pin, described motion bar on needle stand is fixed in one end, be fixed with public slide on the described motion bar, described public slide and the contact slidably mutually of female slide, the other end of described motion bar is connected with an end of rocking arm rotationally, described rocking arm is connected by second turning cylinder rotationally with the rocking arm rotation seat, the other end of described rocking arm rotates with hydraulic jack by first turning cylinder and is connected, the length of the rocking arm section between described first turning cylinder to the second turning cylinder is first length, described second turning cylinder is second length to the length at the place of being rotationally connected between motion bar and the rocking arm, and described second length is greater than first length.
The other end of described motion bar has jack, and an end of described rocking arm is inserted in the described jack.
A described end that is positioned at the rocking arm of jack has sphere.
The utility model compared with prior art has following advantage:
Because second length is greater than first length, so the less stroke of hydraulic jack can cause the bigger stroke of motion bar, and then the point-to-point speed of motion bar is accelerated, and can carry out punching to workpiece apace, and the pressure of punching is big.
Description of drawings
Accompanying drawing 1 is for the utlity model has two structural front view of overlapping the speed increasing mechanism of hydraulic piercing presses;
Accompanying drawing 2 is for the utlity model has two structural front view (structural front view after hydraulic jack drives) of overlapping the speed increasing mechanism of hydraulic piercing presses; Wherein:
