Description
Technical field
The utility model relates to a kind of mold, in particular to a kind of accurate flanging die.
Background technique
Existing stamping die is generally made of punch-pin and cavity plate, but punching machine can be only done a stamping procedure, is carried out
Flanging die is recycled to carry out flange after stamping procedure, process is many and diverse, and the mold and equipment used is all more, greatly influences life
The efficiency of production.
Utility model content
The precision die with flange can be punched out simultaneously the technical problem to be solved by the present invention is to provide one kind.
The technical solution of the utility model are as follows:
A kind of precision flanging die, including the upper mold core and lower mold core matched, the upper mold core includes cope plate and company
Connect the stake of rushing below cope plate, described to rush stake and be from top to bottom successively made of upper overturning section and punching section, the upper overturning section
Round table-like for arc, top side face is tangent with cope plate, and bottom side and punching section are tangent；It is offered in the lower mold core and punching section
The punching of cooperation, the punching top are punching step, the punching step lower flange section and lower die round table-like by arc
The connection of core upper surface；The punching bottom side is equipped with pile jacking.
Further, lower flange section and lower mold core upper surface are tangent.
Further, upper overturning section and lower flange section its section in be punched state are isocentric circular arc, and circular arc partly
Diameter difference is the thickness of steel plate.
Further, punching section bottom edge opens up fillet.
Further, fillet is 10-15 ° of fillet.
The utility model has the beneficial effect that
The process that the utility model can complete punching and flange using a set of equipment, is not required to be turned over again after being first punched
Side simplifies process, improves the efficiency of production, and steel plate extends in lower flange section under the punching press of punching section to lower recess,
Steel plate is punched out until punching section reaches punching top position, is punched undershoot blank.Then it rushes stake to continue traveling downwardly, at this time steel
The remainder that plate extends in lower flange section to lower recess completes overturning process under the extruding of upper overturning section and lower flange section,
Utilize pile jacking by punching material ejection after the completion of flange, pile jacking can be designed as hydraulic-driven.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is utility model works schematic illustration.
In figure: 1- upper mold core, 11- cope plate, 12- flange section, 13- are punched section, 2- lower mold core, 21- bending section, 22- punching
Cut step, 23- punching, 3- pile jacking, 4- steel plate, 41- flange, 42- punching material.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
It is as shown in Figs. 1-2:
A kind of precision flanging die, including the upper mold core 1 and lower mold core 2 matched, the upper mold core 1 includes cope plate 11
It is described to rush stake and be from top to bottom successively made of upper overturning section 12 and punching section 13 with the stake of rushing for being connected to the lower section of cope plate 11, institute
Stating upper overturning section 12 is that arc is round table-like, and top side face and cope plate 11 are tangent, and bottom side and punching section 13 are tangent；The lower mold core
The punching 23 cooperated with punching section 13 is offered in 2,23 top of punching is punching step 22, and the punching step 22 passes through
The round table-like lower flange section 21 of arc is connect with 2 upper surface of lower mold core；23 bottom side of punching is equipped with pile jacking 3.
As shown in Fig. 2, first the steel plate for needing piercing and flanging is placed in lower mold core 2 when use, upper mold core 2 is then depressed,
Steel plate 4 extends in lower flange section 21 under the punching press of punching section 13 to lower recess first, until punching section 13 reaches punching 23
Top position is punched out steel plate, is punched undershoot blank 42.Then it rushes stake to continue traveling downwardly, steel plate 4 extends to lower recess at this time
Remainder in lower flange section 21 completes overturning process under the extruding of upper overturning section 12 and lower flange section 21, and flange is completed
Afterwards using pile jacking 3 by 42 ejection of punching material, pile jacking 3 can be designed as hydraulic-driven.
Specifically, in order to which flange being capable of even transition, the stress reduction for being as far as possible subject to material, lower flange section 21 and lower die
2 upper surface of core is tangent.
Unevenly cause wall thickness at flange inconsistent specifically, not will cause material stretching during for flange, on
Flange section 12 and lower flange section 21 its section in the state of punching are isocentric circular arc, and the semidiameter of circular arc is the thickness of steel plate 4
Degree, ensures that the thickness of the thickness and steel plate 4 of flange 41 is consistent during flange in this way.
Specifically, entering punching for the ease of punching section 13, punching 13 bottom edge of section opens up fillet.
Specifically, fillet is 10-15 ° of fillet.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
