Abstract

The utility model provides a multi-station gear-shaving fine punching mold, which is used for punching multi-gear parts step by step by using a plurality of punching stations, reducing a sunk angle of a punching piece and improving the mechanical performance of the punching piece. The multi-station gear-shaving fine punching mold for a multi-gear punching piece comprises an upper die and a lower die, which clamp the punching piece and are in convex-concave fit, wherein the upper die comprises an upper template, an upper pad plate and a male die; the upper pad plate is fixed on the upper template; the male die is arranged below the upper pad plate; punches are arranged on the male die; the lower die comprises a lower template, a lower pad plate and a female die; the lower pad plate is fixed on the lower template; the female die is arranged on the lower pad plate; a plurality of punching stations are arranged on the male die and face a multi-gear part of the punching piece; each punch is arranged at each station; a plurality of edge-cutting punches and a final molding punch are sequentially arranged from outside to inside; the dimension which is punched by each edge-cutting punch is approximate to the dimension of the multi-gear part of the punching piece; and the dimension of the final molding punch is equal to that of the punching piece. By adoption of the multi-station gear-shaving fine punching mold, the quality of a punching section can be improved, the sunk angle of the multi-gear part of the punching piece is reduced, and the mechanical performance of the punching piece is improved.

Description

The multistation of using for multiple tooth stamping parts picks the tooth fine blanking die

Technical field

The utility model relates to a kind of reducing with the tooth stamping parts fine blanking die at angle that collapses, and is specially adapted to reduce the collapse fine blanking die at angle of multiple tooth stamping parts tooth section.

Background technology

Diel is that material is carried out the equipment that pressure processing is used, and its operation principle generally is to drive the folding of patrix and counterdie and the setting such as raw material between with it cut, punching, stretching under the effect of punching press by mould, the formation stamping parts.According to the operation principle of forcing press, can be divided into mechanical press and hydraulic press.Mechanical press is to finish punching course by the Motor Drive slide block movement, and hydraulic press is by hydraulic principle, drives the hydraulic cylinder reciprocating motion and finishes punching course.Mechanical press work reciprocating frequence is fast, and speed is high, and efficient is high, but the power that produces is less, generally is used for mini-type punching equipment, and punching, shearing technique.The force rate that the hydraulic pressure function produces is larger, but speed is slower, and is general for stretching, moulding production, also is used for punching press and the shearing of heavy parts.

Fine blanking die is that present existing product is made the novel mould in field.It is combined by the punch-die that cooperates up and down usually, and punch-die is fixed by upper padding plate, and upper padding plate and cope match-plate pattern are fixed.At present the multiple tooth part of punching press all adopts to settle punching type at one go, and the angle of collapsing of the part tooth section after the punching press is larger like this, and this mode can not satisfy the part of being had relatively high expectations in the angle of collapsing.

The utility model content

Technical problem to be solved in the utility model is the technical deficiency for above-mentioned existence, provide a kind of employing a plurality of punching press stations, progressively punching press is carried out at multiple tooth part position, reduced the angle of collapsing of stamping parts, the multistation that improves the mechanical property of stamping parts picks the tooth fine blanking die.

The technical scheme that its technical problem that solves the utility model adopts is:

The multistation of using for multiple tooth stamping parts picks the tooth fine blanking die, include the upper and lower mould of the convex-concave cooperation that clamps stamping parts, patrix comprises cope match-plate pattern, upper padding plate and punch, be fixed with upper padding plate on the cope match-plate pattern, install punch under the upper padding plate, punch is provided with drift, counterdie comprises lower bolster, lower bolster and die are fixed with lower bolster on the lower bolster, install die on the lower bolster, it is characterized by: the multiple tooth position over against stamping parts on punch is provided with a plurality of punching press stations, each station is equipped with drift, is followed successively by from outside to inside a plurality of cutting edge drifts and last forming punching head, and the size after each cutting edge drift stamping-out, close to the size at the multiple tooth position of stamping parts, size and the stamping parts of last forming punching head are measure-alike successively.

In such scheme, described punching press station has three at least.

In such scheme, the profile of tooth that the first in the described punching press station rushes tooth is apart from the stamping parts castellated edge surplus of 5mm at least.

Principle of the present utility model is to utilize the method for progressively picking tooth to realize punching press to multiple tooth parts, shear stress in the time of with the minimizing punching press, the profile of tooth of at first punching press has more the above surplus of 5mm than the castellated edge that stamping parts requires, then utilize follow-up punching press station to gradually reduce surplus, last punch shape and stamping parts are identical, finish the punching press to part.

The beneficial effects of the utility model are: can improve the stamping-out cross section quality, reduce the angle of collapsing at the multiple tooth position of stamping parts, improve the mechanical property of stamping parts.

The specific embodiment

Below in conjunction with the specific embodiment, the utility model is further described:

The multistation for multiple tooth stamping parts used shown in Figure 3 such as Fig. 1 Fig. 2 picks the tooth fine blanking die, include the upper and lower mould of the convex-concave cooperation that clamps stamping parts 7, patrix comprises cope match-plate pattern 1, upper padding plate 2 and punch 3, be fixed with upper padding plate 2 on the cope match-plate pattern 1, upper padding plate is installed punch 32 times, punch 3 is provided with drift, counterdie comprises lower bolster 4, lower bolster 5 and die 6, be fixed with lower bolster 5 on the lower bolster 4, install die 6 on the lower bolster 5, wherein the multiple tooth position over against stamping parts 7 is provided with three punching press stations on punch 3, is separately installed with from outside to inside to be equipped with the first drift 8, the second drift 9, the 3rd drift 10, wherein the first drift 8, the second drift 9 is the cutting edge drift, the 3rd drift 10 is forming punching head, and the size after each cutting edge drift stamping-out, descending successively close to the size at stamping parts 7 multiple tooth positions, the 3rd drift 10 shapes and stamping parts 7 are identical.

In the present embodiment, the profile of tooth that described the first drift 8 rushes tooth is apart from the stamping parts 7 castellated edge surplus of 5mm at least.

The utility model is to utilize the method for progressively picking tooth to realize punching press to multiple tooth parts, shear stress in the time of with the minimizing punching press, the profile of tooth of at first the first drift 8 punching presses has more the above surplus of 5mm than the castellated edge that stamping parts 7 requires, then utilize follow-up punching press station to gradually reduce surplus, last the 3rd drift 10 shapes and 7 of punching presses are identical, finish the punching press to part.

The utility model can improve the stamping-out cross section quality, reduces the angle of collapsing at stamping parts 7 multiple tooth positions, improves the mechanical property of 7 of punching presses.
