Description
Technical field
The present invention relates to stepping punching mould, specifically refer to for existing progressive die carry out it is anti-breaking fall technological transformation, use
Anti-breaking fall to hanging the progressive die punch device of bolt in a kind of being provided with for eliminating secondary destruction hidden danger of breaking.
Background technology
Stepping punching mould abbreviation progressive die, banding Metal plate abbreviation strip;Progressive die is a kind of multistation, continuous punching
Pressure, by the mould of the strip punch forming sheet metal product of the grading movement of substep, the progressive stamping frequency of progressive die can reach often
Minute tens to hundreds of times, a secondary progressive die generally has numerous punch-pin and cavity plate corresponding with punch-pin, in real work,
The punch-pin of progressive die can occur brisement because of fatigue of materials at the connection end being connected with punch-pin support plate, and the punch-pin of brisement can be along
The pilot hole for being oriented to holding pad drops down between cavity plate and strip, and is continued by the strip entrainment of continuous grading movement is mobile
Expand damage envelope, i.e. produce secondary damage, because the progressive stamping frequency of progressive die is quite fast, when member to be operated realizes,
Whole progressive die receives cannot repair the damage of degree already.
Fall to causing secondary damage to prevent punch-pin fatigue from breaking, prior art starts to use for the progressive die of new production
The hanging platform method of recent invention is taken precautions against, i.e. one is set at the connection end that punch-pin is connected with punch-pin support plate and is pressed more than guiding
The hanging platform of the pilot hole of flitch, when punch-pin occurs unexpected fracture, the punch-pin of fracture is hooked on guiding holding pad by the hanging platform
Pilot hole in, prevent the punch-pin of fracture from continuing the generation secondary damage that drops down, by the way that control will be damaged at primary place, protect
Other reparations of intact part in order to after of progressive die entirely;
Because hanging platform method needs to carry out accessory processing transformation to punch-pin and punch-pin support plate simultaneously, for having shaped, it is difficult to
Using hanging platform method carry out it is anti-breaking fall technological transformation progressive die, i.e. existing progressive die, prior art using mechanical resistant fatigue
Material makes punch-pin, and takes the measure for regularly updating punch-pin to be taken precautions against, nonetheless, due to progressive die real work operating mode
Uncertainty, punch-pin is still present the risk hidden danger of the disconnected raw secondary damage of shaving one's head of fatigue;Therefore, it is grading for existing
Mould, prior art exist break fall secondary damage risk, be difficult to it is anti-breaking fall technological transformation problems and shortcomings.
The content of the invention
For the problems and shortcomings that above-mentioned prior art is present, the present invention is using by punch-pin, extension bolt and punch-pin support plate structure
Into device, wherein, above the connection end of punch-pin set a blind screwhole, hang bolt top be provided with hook flange, punch-pin
Support plate sets a support plate perforation corresponding with the blind screwhole, after punch-pin is connected with punch-pin support plate, hangs bolt and slides from top to bottom
It is dynamic to be fixedly connected with the blind screwhole through support plate perforation, below the hook flange with punch-pin support plate above between
It is provided with hook gap;
When punch-pin occurs unexpected fracture, the extension bolt hooks the punch-pin for being broken tenesmus, makes the punch of punch-pin
Remain at and be oriented in the pilot hole of holding pad, prevent the punch-pin of fracture from continuing the generation secondary damage that drops down;Between hook
The effect of gap is:When punch-pin is broken, it is ensured that the extension bolt does not stress, it is to avoid hang bolt in company with the fracture of punch-pin
It is broken simultaneously;Additionally, hooking gap also has indicative function, when punch-pin is broken, the convex of fracture tenesmus is hooked because hanging bolt
Mould makes to be contacted with above punch-pin support plate below the hook flange, hooks gap and disappears, and this is easy to operator to realize in time,
Fault spread is avoided, working drawing is also easily accessible for service and is really found impaired punch-pin;The present apparatus is saved from damage by will damage control at primary place
Other intact parts of progressive die are particularly suitable for needing the existing progressive die for regularly updating punch-pin to be prevented in order to repair
Break the technical scheme of technological transformation of falling, there is provided a kind of being provided with anti-breaking falls to hanging the progressive die punch device of bolt, it is intended to make existing
Progressive die, reach avoid secondary damage, be convenient for it is anti-breaking fall technological transformation purpose.
The object of the present invention is achieved like this:It is a kind of be provided with it is anti-breaking fall to hanging the progressive die punch device of bolt, it is including convex
