Abstract
The invention relates to a U-shaped nail symmetric punching and positioning mechanism which comprises gear seats; two positioning devices are symmetrically arranged in the gear seats; any one positioning device respectively comprises a positioning arm and a support seat; the upper end of the positioning arm is fixedly provided with a gear; the gears on the upper ends of the two positioning arms are mutually engaged; the gears are arranged in the gear seats through gear shafts; a spring is connected between the symmetric positions of the two positioning arms; the lower ends of the positioning arms are provided with shifting forks; the opposite side surfaces of the two shifting forks are in oblique surface shapes; the lower ends of the shifting forks are in arc-shaped surface shapes; the upper ends of the support seats are respectively provided with a roller through a connecting shaft; and the outer peripheries of the rollers are respectively tangential to the arc-shaped surfaces of the shifting forks above the rollers. According to the U-shaped nail symmetric punching and positioning mechanism, the two positioning devices which are symmetrically arranged adjust a central point of a U-shaped nail to be processed to a punching central path of a punch, so that the pin height is kept consistent when in formation, and the product quality is improved.
Description
Technical field:
The present invention relates to mechanical field, particularly relate to the device being manufactured U-shaped nail by process for stamping, particularly a kind of U-shaped nail symmetric punching detent mechanism.
Background technology:
In prior art, when manufacturing U-shaped nail by process for stamping, punching press is carried out at the middle part that U-shaped nail directly aimed at by drift, can not ensure that punching press point is positioned at the symmetrical centre of U-shaped nail, easily occurs the situation of U-shaped nail HEM NOT LEVELED after punching press.
Summary of the invention:
The object of the present invention is to provide a kind of U-shaped nail symmetric punching detent mechanism, described this U-shaped nail symmetric punching detent mechanism will solve the technical problem easily occurring HEM NOT LEVELED when punching press in prior art is U-shaped follows closely.
This U-shaped nail symmetric punching detent mechanism of the present invention, comprise pinion stand, wherein, two positioners are symmetrically arranged with in described pinion stand, positioner described in any one all each freedom registration arm and a supporting seat are formed, the upper end of the registration arm described in any one is all fixedly installed a gear, the described gear of two registration arm upper ends engages each other, the circle centre position of any one gear is provided with gear hole, gear shaft is provided with in gear hole described in any one, gear shaft described in any one is all arranged in pinion stand, a spring is connected with between the symmetric position of the registration arm in two positioners, the lower end of any one registration arm is provided with a fork, the side in opposite directions of the fork in two positioners is all in inclined-plane, the lower end of fork is all in cambered surface, the upper end of the supporting seat described in any one is all provided with a roller each via connecting axle, the excircle of the roller described in any one respectively with its above fork lower end cambered surface tangent.
Further, the side in opposite directions of two described forks is trapezoidal profile, and described is trapezoidal wide at the top and narrow at the bottom.
Further, the mid point of described spring is positioned in the symmetrical center line of two positioners.
Operation principle of the present invention is: put between the fork of two positioners by U-shaped nail to be processed, drift is along the U-shaped nail punch pressure of symmetrical centre alignment of two positioners, when U-shaped nail is subject to the pressure of drift, transfer the pressure to fork, if the point midway of U-shaped nail departs from the symmetrical center line of two positioners, the fork discontinuity equalization on both sides, fork is by the mutual transmitting forces of pitch wheel of registration arm and registration arm upper end, U-shaped nail is adjusted position on the inclined-plane in opposite directions of two forks, until both sides fork stress equalization, the point midway of U-shaped nail is positioned at the symmetrical center line of two positioners this moment, drift continues punching press, complete the shaping of U-shaped nail, HEM NOT LEVELED is there is not when ensureing shaping.
The present invention compares with prior art, and its effect is actively with obvious.The mid point of U-shaped nail to be processed is adjusted on the punching press center path of drift by two symmetrically arranged positioners by the present invention, does not occur HEM NOT LEVELED when can ensure shaping, improves the quality of product.
