Abstract
The utility model discloses a step-type flanging die which comprises a male die, a left female die, a right female die, a lower die base and an ejecting block. The lower die base is provided with a left side wall and a right side wall. The left female die is movably arranged on the left side wall of the lower die base through a first shaft. The right female die is movably arranged on the right side wall of the lower die base through a second shaft. The left female die and the right female die are symmetrically arranged. The upper surface of the left female die is step-shaped. The structure of the right female die and the structure of the left female die are in mirror symmetry. The bottom of the male die is in a step shape which is matched with the left female die and the right female die. The ejecting block is arranged at the bottom of the middle junction between the left female die and the right female die. A locating groove is formed in the lower die base, and the ejecting block slides up and down in the locating groove. An elastic body is arranged between the ejecting block and the bottom of the locating groove. The step-type flanging die is capable of accomplishing step-type flanging operation in one stroke of a punch press, and is low in production cost and high in production efficiency.
Description
Technical field
The utility model relates to the cold punching technology processing technique field, is specifically related to a kind of step flanging die.
Background technology
The cold punching technology processing technique field for step multiple tracks flange, is generally repeatedly flanging forming and just can finishes processing; Also can adopt the compound die once-forming, the compound die of existing step multiple tracks flange is made up of punch, multistage die, is provided with spring or rubber spring between the dies at different levels.There is inefficiency in multiple working procedure processing, the problem that processing cost is high, and the compound die of once-forming also exists spring or rubber spring price height, composite die manufacturing cost height, and compound die short problem in service life, in addition, multistage spring or rubber spring repeatedly use the back because flexibility decrease, cause the workpiece fold easily, processing effect is not good.Therefore the mould that needs the exploitation new construction is to overcome the problems referred to above.
Summary of the invention
The purpose of this utility model is to provide a kind of step flanging die, can finish the operation of step multiple tracks flange in the one stroke of punch press or hydraulic press, and production cost is low, the production efficiency height, and simple in structure, need not to use multistage spring, long service life, the Mold Making cost is low.
To achieve these goals, the technical scheme that the utility model proposes is:
A kind of step flanging die, comprise punch, left side die, right die, die shoe, jacking block, described die shoe is provided with left side wall and right side wall, described left die is movably set in the left side wall of described die shoe by axle one, described right die is movably set in the right side wall of described die shoe by axle two, and described left die and described right die are for being symmetrical arranged, described left die upper surface is a step, the structure of described right die becomes the mirror image symmetry with left die, the step of described punch bottom for matching with described left die and right die, the middle meet bottom of described left die and right die is provided with jacking block, described die shoe is provided with the locating slot that slides up and down for described jacking block, is provided with elastomer between described jacking block and the described locating slot bottom.
Before the processing, described left die and right die are upturned under described jacking block effect, after described punch was descending, described left die and right die be upset downwards gradually, finally finished the processing operation of step flange workpiece under the common pressing effect of punch and left die, right die.The step flanging die of described structure can be realized flanging forming by the turnover working sheet, has reduced the material shifts and the discontinuity that flow and cause thus of material, is out of shape the generation of bad phenomenon such as inhomogeneous.
As the further improved step flanging die of the utility model, the described elastomer that is provided with between described jacking block and the described locating slot bottom is spring or rubber spring.
Step flanging die provided by the utility model can be finished the operation of step multiple tracks flange in the one stroke of punch press or hydraulic press, production cost is low, the production efficiency height, and simple in structure, need not to use multistage spring, long service life, the Mold Making cost is low.
Description of drawings
Fig. 1, the structural representation the during pressing of step flanging die;
Fig. 2, the structural representation before the pressing of step flanging die.
1 is punch, and 2 is left die, and 3 is right die, and 4 is die shoe, and 5 is jacking block, and 6 is left side wall, and 7 is right side wall, and 8 is that axle one, 9 is that axle two, 10 is a locating slot, and 11 is elastomer.
The specific embodiment
In order to deepen to understanding of the present utility model, the utility model is done describing in further detail below in conjunction with drawings and Examples, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Shown in Fig. 1-2, the step flanging die that present embodiment provided, comprise punch 1, left side die 2, right die 3, die shoe 4, jacking block 5, described die shoe 4 is provided with left side wall 6 and right side wall 7, described left die 2 is movably set in the left side wall 6 of described die shoe 4 by axle 1, described right die 3 is movably set in the right side wall 7 of described die shoe 4 by axle 29, and described left die 2 and described right die 3 are for being symmetrical arranged, described left die 2 upper surfaces are step, 2 one-tenth mirror image symmetries of the structure of described right die 3 and left die, the step of described punch 1 bottom for matching with described left die 2 and right die 3, the middle meet bottom of described left die 2 and right die 3 is provided with jacking block 5, described die shoe 4 is provided with the locating slot 10 that slides up and down for described jacking block 5, is provided with elastomer 11 between described jacking block 5 and described locating slot 10 bottoms.
Before the processing, described left die 2 and right die 3 are upturned under described jacking block 5 effects, after described punch 1 was descending, described left die 2 and right die 3 be upset downwards gradually, finally finished the processing operation of step flange workpiece under the common pressing effect of punch 1 and left die 2, right die 3.The step flanging die of described structure can be realized flanging forming by the turnover working sheet, has reduced the material shifts and the discontinuity that flow and cause thus of material, is out of shape the generation of bad phenomenon such as inhomogeneous.
Further improve as present embodiment, the described elastomer 11 that is provided with between described jacking block 5 and described locating slot 10 bottoms is spring or rubber spring.
The step flanging die that present embodiment provided can be finished the operation of step multiple tracks flange in the one stroke of punch press or hydraulic press, production cost is low, the production efficiency height, and simple in structure, need not to use multistage spring, long service life, the Mold Making cost is low.
