Deng having direct relation with mold design and manufacture.The height of Mould design and manufacturing technical merit, is to weigh a national product
One of important symbol of manufacture level height, largely decides the exploitation energy of the quality, benefit and new product of product
Power.
It is fast in order to be formed in the prior art, it is necessary to carry out step pitch positioning to material strip in the process of continuous stamping die
The step pitch positioning of speed and low cost, can be by the way of being positioned, as shown in figure 1, in material by the both sides side edge to material strip
Both sides cut off breach and form side edge 11 on band 1, so as in the formation step pitch of material strip 1, block 12 then being set on mould, is passed through
Contact between block 12 and the edge of a knife of side edge 11 realizes that step pitch is positioned.But, this step pitch positioning method is needed for material strip
Both sides reserve waste part, the waste part that substantial side edge cuts off out can not be reclaimed substantially, waste material,
Add the cost of processing.
Utility model content
The purpose of this utility model is to be directed to deficiency of the prior art, and provides a kind of continuous punching with step pitch function
Compression mould, can save material strip material using the mould, reduce cost.
The purpose of this utility model is achieved through the following technical solutions：A kind of continuous stamping die with step pitch function, bag
The upper die and lower die set from top to bottom successively are included, in addition to：Upper convex closure drift, its bottom is fixedly mounted on mould, its top
Extend downwardly and be provided with the boss for being molded convex closure；Lower convex closure drift, its bottom is fixedly mounted on lower mould, and its top is prolonged upwards
Stretch and offer the cavity for being molded convex closure；Locating part, its bottom is resiliently attached to the lower mould, and its top is to the bottom of material strip
Portion extends；Along material strip direct of travel, the locating part is located at the rear of lower convex closure drift.
Wherein, the lower mould is additionally provided with floating pin, and the bottom of the floating pin is resiliently attached to lower mould, the floating pin
Top upwardly extends and passes through the cavity.
Wherein, the length of the boss in the height direction is three millimeters.
Wherein, the locating part is gag lever post or limited block.
The beneficial effects of the utility model：The continuous stamping die with step pitch function of the application, in original continuous punching
On the basis of punch die, by adding upper convex closure drift, lower convex closure drift and locating part, when material strip is by mould, pass through
After mould first time matched moulds, under the mating reaction of upper convex closure drift and lower convex closure drift, material strip formation convex closure, then material strip after
Continue into the top of, locating part and to be positioned by contradicting the step pitch of the paired material strip of the convex hull-shaped, then by second of matched moulds of mould after,
It is driven plain at convex closure, now locating part is eliminated to the positioning action of material strip, and material strip is continued on to next process, direct material strip
Positioned, constantly circulated with this, compared with prior art, above-mentioned step pitch positioning method is than the two of material strip by mould step pitch again
Side carries out incised notch mouth and is positioned to save material, reduces and wastes, reduces cost.

Embodiment
The utility model is further described with the following Examples.
A kind of embodiment of continuous stamping die with step pitch function of the present utility model, as shown in Fig. 2 including
The upper mould 2 and lower mould 3 set from top to bottom successively, upper mould 2 can include upper bolster, upper padding plate, train wheel bridge, baffle plate, de- material
Plate etc., lower mould 3 can include lower template, lower bolster and die shoe.Structure of mould 2 and lower mould 3 is all continuous stamping die on these
Generally used in tool, the present embodiment is applied in the improvement of the present embodiment as example and is specifically described.
As continuous stamping die improvement part, as shown in Fig. 2 continuous stamping die also includes upper convex closure drift 4, its bottom
End is fixedly mounted on by way of being spirally connected in upper mould 2, and the top of upper convex closure drift 4 extends downwardly the bottom surface of supreme mould 2 and set
There is the boss 41 for being molded convex closure；Lower convex closure drift 5, its bottom is fixedly mounted on by way of being spirally connected in lower mould 3, under it is convex
The top of bag drift 5 extends upwardly to the top surface of lower mould 3 and offers cavity for being molded convex closure；Locating part 6, its bottom leads to
