Abstract
The invention relates to an exceeding-type shearing die structure which comprises an upper shearing die sleeve and a lower alloy die. A shearing die is arranged inside the upper shearing die sleeve, and a hole is formed at the center of the shearing die. An alloy insert is embedded in the end portion of the lower alloy die. A material returning bar is arranged in the middles of the lower alloy die and the alloy insert. A shearing boss is formed at the head of the alloy insert. The outer diameter of the shearing boss is smaller than the diameter of the internal hole of the shearing die. Through the structure, edges can be cut off by one step during shearing, and tearing caused by pulling is avoided, so that products are prevented from being pulled and bent, cuts are burr-free, product qualification rate is increased, product quality is improved, and product cost is reduced.
Description
Technical field
The present invention relates to a kind of mould structure in the five metals manufacturing, especially relate to a kind of override type shaving die structure.
Background technology
At present, in the five metals manufacturing, it is different according to demand that to need the shape of the head of screw also be of all kinds, so just need to be to the processing of cutting edge of the head of semi-finished product screw, traditional side cut shape technique edger 2 and alloy counterdie 6 die orifice end faces maintain the spacing about 0.5mm as shown in Figure 1, edger 2 die orifices do not allow to run on the alloy counterdie 6, as the easily damage edger 2 that collides, and the part of spacing is torn to withdraw from when realizing the material returned by material returned rod 7 and is realized cutting the haircut type, yet partially thin for head dummy, capitiform thickness only has 1.5mm, and the capitiform broadside reaches 20mm, and thickness and Length Ratio reach more than 13 times, use above explained hereafter, cut rear product 5 heads and break the required power meeting of spacing stretch bending head, particularly long limit owing to tearing, bending can reach more than the 1.5mm.Can not reach drawing requirement at all, only have the operation of increasing smoothing, increase like this cost, product quality is unsecured again, and the ratio of scrapping reaches about 15%.
Summary of the invention
Technical problem to be solved by this invention provides a kind of easy to operate override type shaving die structure simple in structure, does not need to increase operation during use, can reduce product cost, and can guarantee the quality of product.
The present invention solves the technical scheme that its technical problem takes: a kind of override type shaving die structure, comprise side cut Upper Die-sleeve and alloy counterdie, described side cut Upper Die-sleeve inside is provided with the porose edger of center band, described alloy counterdie end is embedded with alloy and inserts, the centre position of inserting at alloy counterdie and alloy is provided with material returned rod, the described alloy head of inserting is provided with the side cut boss, and the external diameter of side cut boss is less than the diameter of edger internal holes.
Further concrete, the gap between described side cut boss and the edger is 0.05～0.08mm.
Further concrete, the height of described side cut boss is 10mm.
Further concrete, described side cut boss and edger endoporus are rectangle.
The invention has the beneficial effects as follows: adopt after the said structure, in cutting, can cut away the limit is disposable, can not occur pullling and tear phenomenon, so product can not pullled bending, otch has improved the qualification rate of product and the quality of product without burr, has reduced the cost of product.
Description of drawings
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present invention;
Fig. 3 is the structural representation that alloy of the present invention is inserted.
Among the figure: 1, side cut Upper Die-sleeve; 2, edger; 3, screw; 4, smear metal; 5, product; 6, alloy counterdie; 7, material returned rod; 8, alloy is inserted; 9, side cut boss.
The specific embodiment
A kind of override type shaving die structure as shown in Figure 2, comprise side cut Upper Die-sleeve 1 and alloy counterdie 6, the described side cut Upper Die-sleeve 1 inner porose edger 2 of screw 3 fixed center bands that passes through, described alloy counterdie 6 ends are embedded with alloy and insert 8, be provided with material returned rod 7 in insert 8 centre position of alloy counterdie 6 and alloy, shown in described alloy 8 heads of inserting be provided with sharp side cut boss 9, the external diameter of side cut boss 9 is less than the diameter of edger 2 internal holes.
Use as shown in Figure 3 override type side cut structure, the square size design of alloy counterdie 6 head lengths is less by 0.12～0.15 than product capitiform size, high 10mm (reserves 1～3 millimeter that surmounts, the thickness that also has 2～3 products also has some gaps) side cut boss 9 is 0.05～0.08mm with the gap of edger 2.Allow edger 2 nibs surmount 1～3mm on the side cut boss 9 that is inserted in alloy counterdie 6, product 5 heads are cut entirely cut, produce to tear when fundamentally not having the material returned again and break, material returned rod 7 is just released edger 2 to product 5 and is finished production, product is smooth and perpendicular to bar section, and otch is without burr.
In the time of work, side cut Upper Die-sleeve 1 is done mould assembling action with edger 2 and alloy counterdie 6, product 5 is placed on alloy and inserts in 8 interstitial holes, edger 2 and 9 combinations of side cut boss are with product 5 cutting rectangularities, and smear metal 4 is pushed on side cut boss 9 necks, by material returned rod 7 product 5 is ejected afterwards, namely finish whole operating process.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
