Abstract

The utility model discloses a stamping flanging die which comprises a male die, a female die, a female die base plate, a pressing block, an upper wedge-shaped sliding block and a lower wedge-shaped sliding block. A wedge-shaped plane is formed on the bottom at the right end of the upper wedge-shaped sliding block, and a wedge-shaped plane is formed on the top at the right end of the lower wedge-shaped sliding block. The upper wedge-shaped sliding block and the lower wedge-shaped sliding block are movably arranged on the right side of the male die. A first spring is horizontally arranged between the upper wedge-shaped sliding block and the male die, and a second spring is horizontally arranged between the lower wedge-shaped sliding block and the male die. The lower wedge-shaped sliding block is arranged on the bottom of the male die, and the upper wedge-shaped sliding block is located above the lower wedge-shaped sliding block. The female die is fixedly arranged on the female die base plate and is located on the right side of the male die. The pressing block capable of moving up and down is arranged on the left side wall of the female die. The die is a combined die which can finish flanging operation during a punch press one-time stroke, so that production cost of the flanging operation is reduced, and production efficiency is improved.

Description

A kind of punching press flanging die

Technical field

The utility model relates to the cold punching technology processing technique field, is specifically related to a kind of punching press flanging die.

Background technology

Crooked flanging forming is common a kind of processing technology in the cold punching die processing, the workpiece after the processing of edge flanging process, and the mechanical strength at its edge can be significantly increased, and obtains service life prolonging, and has the advantage of sharp edge abate in addition.

Common flange operation needs multiple working procedure just can finish, so the processing cost height, and working (machining) efficiency is low.Need design and develop a kind of composite die that can in the punch press one stroke, finish the flange operation, to overcome above-mentioned deficiency.

Summary of the invention

The purpose of this utility model is to provide a kind of punching press flanging die, can finish the composite die of flange operation in the punch press one stroke, thereby reduces the production cost of flange operation, and enhances productivity.

To achieve these goals, the technical scheme that the utility model proposes is:

A kind of punching press flanging die, comprise punch, die, the die backing plate, briquetting, last wedge block, following wedge block, described upward wedge block right-hand member bottom is a lozenges, described wedge block right-hand member top down is a lozenges, on described, following wedge block is movably set in described punch right side, and under described, following wedge block respectively and be horizontally disposed with spring one and spring two between the described punch, described wedge block down is positioned at the punch bottom, the described wedge block of going up is positioned at wedge block top down, described die is fixedly arranged on the die backing plate and is positioned at described punch right side, and described die left side wall is provided with briquetting movable up and down.

The mold work principle of said structure is as follows: described workpiece is positioned on the die backing plate, and right-hand member is positioned over the briquetting top, the downward punching press of punch, workpiece bends, following wedge block shrinks left under the ramp effect of workpiece, along with punch continues downward punching press, last wedge block also shrinks left under the ramp effect of workpiece, when the following wedge block of punch bottom arrives the briquetting bottom, under the effect of spring, following wedge block ejects to the right, and makes the workpiece right-hand member form an acute angle with the briquetting acting in conjunction; Punch begins lifting then, and following wedge block shrinks left under the ramp effect of workpiece, along with punch continues upwards lifting, last wedge block ejects to the right under the effect of spring, briquetting is moved downward, thereby it is whole that the acute angle right-hand member of workpiece is driven plain, and promptly finishes whole flange operation.

As the further improved punching press flanging die of the utility model, the described briquetting upper left corner and the lower left corner are arc.Arc is convenient to the power that upper and lower wedge block is converted to the power of vertical direction horizontal direction.

As the further improved punching press flanging die of the utility model, described briquetting left side is semicircle.Semicircle is convenient to processing, and is convenient to the power that upper and lower wedge block is converted to the power of vertical direction horizontal direction.

As the further improved punching press flanging die of the utility model, described die backing plate left end is provided with positioning convex.

As the further improved punching press flanging die of the utility model, also comprise upper bolster and die shoe, described punch is fixedly arranged on described upper bolster, and described die backing plate is fixedly arranged on described die shoe.

Punching press flanging die provided by the utility model can be finished the composite die of flange operation in the punch press one stroke, thereby has reduced the production cost of flange operation, and has improved production efficiency.
