Description
Technical field
The utility model relates to machine die production field, especially a kind of positioning for progressive die punching is filled
It sets.
Background technique
At present in die industry, the punching of progressive die mostly uses greatly the positioning form of pilot pin, the correcting before blanking
Pin is introduced into pre- made hole, is made pre-punched hole and pilot pin position alignment, is played the role of positioning to punching, then blanking
Molding, however punching is in the case where progressive die high-speed punching, it is single that correcting is carried out to punching by pilot pin
Positioning form easily causes the deformation of pre-punched hole, causes positioning inaccurate, so that mould punching goes out rejected part.
Utility model content
The goal of the invention of the utility model is: for the prior art exist: it is single by pilot pin to punching into
Row positioning, will cause pre-punched hole deformation for a long time, and the inaccurate problem of punching positioning provides a kind of for progressive die stamping material
The positioning device of band.
To achieve the goals above, the technical solution adopted in the utility model are as follows:
A kind of positioning device for progressive die punching, including punching and template, the template side setting
There is fixed block, intercept locating piece is placed in the fixed block, is provided with spring in the U-shaped structure of the intercept locating piece, it is described
The rear end of spring is fixedly mounted in the circular hole of fixed block, and the front end of the spring acts on intercept locating piece, the stamping material
The side of band rushes jagged, the front end of the intercept locating piece and notch cooperation in advance.It should be noted that the present apparatus is in punching
System is rushed after notch and pre-punched hole in advance, before blanking punched molding, so that it is guaranteed that after punching is accurately positioned in a mold
The punching press of blanking forming etc. is carried out again.In addition, notch size and the cooperation of intercept positioning block front end shape, it is ensured that intercept locating piece pair
Punching plays the role of just positioning, spring be intercept locating piece can in fixed block resilient movement, while it is right
Intercept locating piece and notch play a buffer function when acting on.
Further, the fixed block by pin, screw is arranged in a crossed manner is fixed in template.Wherein pin 2, screw
Two are arranged alternately and guarantee that fixed block and intercept locating piece are secured firmly in template.
Further, the shape of the notch is arc-shaped structure shallow after preceding depth.The specific shape of notch, in the device bullet
Under the cooperation of spring, it ensure that moving process of the punching in mold cannot can only retreat forward.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1, the effect of utility model device use and pilot pin alignment by union, it is fixed with utility model device intercept first
Position block and notch cooperation carry out coarse positioning, then are accurately positioned by pilot pin and pre-punched hole cooperation, and beneficial effect is: this reality
The error that inaccuracy is sent in punching feeding during mold high frequency time punching is eliminated or reduced with the coarse positioning of new device,
Reach pilot pin and when pre-punched hole cooperation positions punching, protection to pre-punched hole reaches pinpoint effect, thus
Solve the problems, such as that progressive die punching positioning under continuous high speed punching is inaccurate.

Specific embodiment
With reference to the accompanying drawing, the utility model is described in detail.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
Embodiment 1 such as Fig. 1-6
A kind of positioning device for progressive die punching, including punching 1 and template 5,5 side of template are set
It is equipped with fixed block 4, intercept locating piece 2 is placed in the fixed block 4, is provided with bullet in the U-shaped structure of the intercept locating piece 2
The rear end of spring 3, the spring 3 is fixedly mounted in the circular hole of fixed block 4, and front end acts on intercept locating piece 2, the stamping material
Side with 1 rushes jagged 6 in advance, and the front end of the intercept locating piece 2 and notch 6 cooperate.
Fixed block 4 by pin 7, screw 8 is arranged in a crossed manner is fixed in template 5.
The shape of the notch 6 is arc-shaped structure shallow after preceding depth.
Specific embodiment: utility model device is mounted on the front end of progressive die mold, and progressive die upper mold is under first
Mould is in discrete state, and punching 1 carries out feeding toward feed direction, when the good notch 6 of punching preparatory on material strip reaches this dress
It sets and is cooperated at intercept locating piece 2, play coarse positioning.Then the upper mold of progressive die pushes, and the pilot pin in upper mold enters
The cooperation of pre-punched hole 9 is accurately positioned, and subsequent upper mold, which continues to push, to be carried out accurate punching press with lower die closed pair punching 1, falls
The processes contents such as material molding.Last progressive die upper mold is separated with lower die again, that is, completes primary complete punching press.In upper mold and lower die
While separation, under the action of feeding thrust, notch 6 is cut punching 1 by handle at the bevel edge cooperation with intercept locating piece 2
It is pushed back away from locating piece 2, spring 3 is now in pressured state, 1 straight line of punching after intercept locating piece 2 by reaching again under
One notch 6 carries out notch cooperation therewith, carries out coarse positioning, and subsequent progressive die upper mold, which pushes, carries out second of accurate punching press.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
