Aperture is slightly less than the embossing tooth of self-clinching nut, and the flower tooth of self-clinching nut is made to squeeze into plate by pressure generates the periphery for leading to hole
Plastic deformation, deformations are squeezed into guide groove, so as to generate the effect of locking.
It presses when product carries out pressing nut riveting because nut progress is single, riveting nut generally use outer diameter is determined
Position, product are usually positioned by positioning mold, and such mode has following defect：1st, because of riveting equipment and riveting nut and product
With the presence of slight change, (riveting machine pressure transient has certain float value, pressing nut tolerance variation and material not to plank
With heat (batch) number or the nuance of steel mill) can all have an impact to pressing, nut is caused to be changed with respect to the verticality at riveting interface, finally
Product relative opening position is caused to deviate, and influences the quality that presses；2nd, the positioning accuracy of positioning mold can also produce the position of relative opening
It is raw to influence so that riveting precision is difficult control；3rd, each single hole carries out the operation that presses, particularly with multiple on a product
Hole needs the situation of self-clinching nut, and production efficiency is not also high.
Utility model content
The purpose of this utility model is to provide a kind of synchronous pressure riveting tool, to solve mentioned above in the background art ask
Topic.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：
A kind of synchronous pressure riveting tool, including upper mold seat and die holder, the upper mold seat bottom surface is equipped with briquetting, the lower die
Be provided with the bar that presses on seat, the briquetting with the bar that presses is vertically opposite on the upper mold seat and the die holder respectively sets
It puts, briquetting lower surface planar structure, it is not straight at one that at least three is respectively equipped on the upper mold seat and the die holder
The opposite briquetting and the bar that presses on line, the bar top surface that presses be equipped with equipped with circular groove, in the circular groove elastic component and
Positioning column, it is described positioning column bottom be fixedly connected with the elastic component, can in the circular groove elastic telescopic, the circular groove and institute
It is coaxial to state positioning column, the positioning column outer diameter matches with riveting nut internal orifice dimension.
Further, the positioning column includes guide plate and cylinder, is additionally provided with partition board in circular groove, the cylinder pass through it is described every
Upward, positioning action, the guide plate is slidably connected plate with the circular groove.The guide plate is located on the inside of the partition board, the column
Body may pass through the through-hole protrusion and the baffle surface.
Further, the positioning column cross section generally " soil " font.
Further, the elastic component is spring.
Further, at the top of the positioning column it is taper or arc-shaped.
Further, the briquetting basal diameter is more than the bar top surface diameter that presses.
The beneficial effect that the utility model generates：1st, by original excircle orientation mode to self-clinching nut, make into
Positioning method is led to by the internal diameter of positioning column by self-clinching nut, improves positioning accuracy, also ensures that nut internal diameter hangs down with riveting face
Straight degree avoids it integral inclined when processing, improves the quality that presses of product.2nd, one is carried out to positions multiple on product
The secondary molding that presses, improves operating efficiency.3rd, positioning column can directly play the role of positioning product, determine without being further added by product
Position device (refering in particular to have at least three preprocessing holes not point-blank on product herein) simplifies the structure of tooling.4、
By at least three, point-blank positioning column can not only not position riveting nut, but also pass through self-clinching nut pair
Preprocessing hole similarly positions on product, avoids the position offset between preprocessing hole and riveting nut on product, improves
The precision of product riveting processing improves the controllability of precision.5th, the design that briquetting bottom surface is more than the shank diameter that presses solves
Existing equipment generates vibration at work, easily easily causes walking for upper mold seat so that briquetting cannot be aligned precompressed position, must
The problem of vertically-guided bar must be used, upper module is slightly offset, and can't influence the effect that presses.
