Abstract

The utility model discloses a continuous pitch positioning die which comprises a convex die plate and a concave die plate, wherein a pitch punch head is arranged on the convex die plate; a material belt depression bar and positioning shifting blocks are arranged on the concave die plate; a punch hole keeping away from the pitch punch head is formed in the material belt depression bar; the positioning shifting blocks are installed on the concave die plate by a spring; the pitch punch head and the concave die plate are vertical to each other; the positioning shifting blocks are vertical to the pitch punch head and vertical to the travel direction of a material belt. According to the continuous pitch positioning die, under the condition that the structure and the strength of the die are not changed, the pitch punch head and the positioning shifting blocks are added, so that the problem of inaccurate positioning of the continuous die during stamping of a shear plate material is completely solved, and then the processing efficiency and the finished product yield are improved and the single piece cost of a product is reduced.

Description

The pitch location progressive die

Technical field

The utility model relates to a kind of pitch location progressive die.

Background technology

Nowadays, hardware dies has 40% for continuous mould in manufacturing, and the advantage that the progressive die is high with its output, efficiency is high, precision is high has played the effect can not be substituted in five metals processing.

Existing continuous mould is in production and processing, consider that Cost Problems often replaces the coiled strip of standard to reduce costs with shear material, and in cost, the bad phenomenon that manually error of feeding causes occurs repeatedly, thereby makes many companies have to abandon cheap shear materials processing and continue to use relatively expensive standard coiled material and produce.

Therefore, feeding error how to avoid low cost shear material to exist in progressive die process, becomes the problem of needing solution badly.

Utility model content

For solving the problems of the technologies described above, the utility model provides a kind of pitch location progressive die, and the feeding error when avoiding progressive die processing shear material realizes the object of accurate feeding in reducing costs.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of pitch location progressive die, comprises convex template and concave template,

On described convex template, be provided with pitch drift, on described concave template, be provided with material strip press strip and be positioned at the location shifting block in described pitch drift downstream, on described material strip press strip, be provided with the punching of avoiding described pitch drift, described location shifting block by spring fitting on described concave template and with described punching at a distance of a pitch;

Described pitch drift is vertical with described concave template to be arranged, and shifting block setting vertical with described pitch drift in described location is also vertical with material strip direct of travel.

Wherein, described location shifting block is provided with two, described in one of them, locate shifting block and be positioned at pitch place, one, downstream of described pitch drift, described in another, locate shifting block be positioned at the end of material strip direct of travel and with described in first, locate shifting block at a distance of N pitch, wherein N is natural number, and N >=1, preferred, between two described location shifting blocks at a distance of 5 pitch.

Pass through technique scheme, the pitch location progressive die that the utility model provides, it is not in the situation that changing mould structure and intensity, after increasing pitch drift and locating shifting block, solve continuous mould completely and in the time of punching press shear material, located inaccurate problem, thereby improve working (machining) efficiency and finished product yield, reduced the cost per unit of product.

Accompanying drawing explanation

In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described.

Fig. 1 is the plan structure schematic diagram of the disclosed pitch of the utility model embodiment location progressive die.

Numeral in figure:

11. concave template 12. material strip press strips 13. are located shifting block 14. pitch drifts

15. material strip 16. pitch breach 17. springs

The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.

With reference to figure 1, the pitch location progressive die that the utility model provides, comprise convex template and concave template 11, the pitch drift 14 being provided with on convex template, on concave template 11, be provided with material strip press strip 12 and be positioned at the location shifting block 13 in pitch drift 14 downstreams, on material strip press strip 12, be provided with the punching of avoiding pitch drift 14, location shifting block 13 is arranged on concave template 11 and with punching at a distance of a pitch by spring 17; Pitch drift 14 setting vertical with concave template 11, location shifting block 13 setting vertical with pitch drift 14 vertical with material strip direct of travel.

Wherein, location shifting block 13 is provided with two, and one of them location shifting block 13 is positioned at pitch place, one, 14 downstream of pitch drift, and another location shifting block 13 is positioned at the end of material strip direct of travel and locates shifting block 13 at a distance of 5 pitch with first.

Operation principle of the present utility model:

First manually material strip 15 is sent in the track of material strip press strip 12;

In the time that material strip 15 enters concave template 11, pitch drift 14 is gone out pitch breach 16 in the first step;

Manual continuation feeding, in the time that contacting with first location shifting block 13, pitch breach 16 has obvious resistance, now just stopping feeding carrying out die-cut and second pitch breach 16 is gone out, then continue feeding, utilize pitch breach 16 and the location circular arc between shifting block 13 to coordinate to force and locate shifting block 13 Compress Springs 17 and retreat, until contacting when first locates shifting block 13, second pitch breach 16 meet obstructions, stop feeding die-cut the 3rd pitch breach 16, so come and go processing feeding until last sheet stock is sent from the location shifting block 13 of afterbody;

Repeat above-mentioned steps and carry out the processing of all the other material strips.

To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to the multiple modification of above-described embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
