Description
Technical field
The utility model relates to tank class special purpose vehicle technical fields, and in particular to a kind of pot body closing end stamping die.
Background technique
Tank body apply in daily life it is extremely wide, the end enclosure structure that the front/rear end of tank body uses have it is irreplaceable
Effect.For circular tank end socket, the manufacture craft of special-shaped pot body closing end is complex, more in production at present to adopt
It is realized with process for stamping.End socket made of punching press requires appearance to coordinate well-balanced, the plastic deformation uniformity of boss, end socket
Periphery beauty, rounding off.
Existing pot body closing end punching die structure is as shown in Figures 1 to 4, including upper mold 1 and sealing element 4, and upper mold 1 is by ring
The stiffening ring 11 and spike plate 13 of shape form, wherein stiffening ring 11 and spike plate 13 can be split type structure (see Fig. 2) can also
To be integral structure (see Fig. 3), the annular position of spike plate 13 is provided with several for increasing 5 frictional force of end socket workpiece
Stud 131 slides to hydraulic pressure direction to avoid end socket workpiece 5, and when punching press, end socket workpiece 5 and mold are placed on hydraulic platform 6, envelope
The peripheral edge 51 of head workpiece 5 is located between spike plate 13 and sealing element 4, and hydraulic cylinder 4 downwards presses to stiffening ring 11, then
Water filling pressurization makes end socket workpiece 5 generate deformation below end socket workpiece 5, in order to guarantee that end socket workpiece 5 compresses, main hydraulic cylinder 4
Pressure at least needs the pressure of 25MPa.Due to the fault of construction of existing pot body closing end stamping die itself, determine it to pressure
There is high requirement in terms of power.However, the drawbacks of high pressure be it is very outstanding, mainly have following problems: (1) high pressure is direct
Result in electric cost rising；(2) high pressure directly results in the high performance requirements to sealing element 4, and thickness reaches about 12mm, and
And high pressure makes sealing element 4 that too fast and cost increase be lost；(3) under high pressure effect, in order to ensure compressing end socket workpiece 5,
Have no alternative but increase the compression area i.e. area of 1 annulus of upper mold that mold corresponds to 5 peripheral edge 51 of end socket workpiece, lead indirectly in this way
(peripheral edge 51 of corresponding mold compression end socket workpiece 5 is in finished product by as useless for the rising of cause 5 cost of raw material of end socket workpiece
Expect and cut off)；(4) it in order to cope with high pressure, avoids die deformation and does not press tightly end socket workpiece 5 or pressure leakage, therefore liquidate
The rigidity requirement of compression mould be it is high, the structure that this results in mold body indirectly is relatively bulky and heavy, is unfavorable for worker
The frequently operation such as lifting, adjustment；Meanwhile the labor intensity of operating personnel is increased, also more safety are brought to operator
Hidden danger.
In addition, existing pot body closing end punching die structure only has upper mold 1 without lower die, and the periphery sides of spike plate 13
Edge 51 is planar structure, and when punching press compresses the peripheral edge 51 of end socket workpiece 5 by the planar structure of spike plate 13 (see figure
4), this allows for end socket workpiece 5 and is easy to happen sliding in punching course walking --- and this is quite dangerous under hyperbaric environment
, it may appear that since the high pressure water that end socket workpiece 5 walks and hydraulic platform 6 is caused to inject is produced at 4 edge of sealing element, to draw
Work safety accident is sent out, therefore there are biggish operation safety hidden danger.
Summary of the invention
The purpose of this utility model is that aiming at the shortcomings in the prior art, and a kind of pot body closing end stamping die is provided,
By changing the defects of existing pot body closing end stamping die structure and Sheet Metal Forming Technology, pot body closing end stamping die is reduced to pressure

Sealing consumptive material usage amount is big, workpiece blank waste of raw materials is big and mold deadweight is big, operating personnel's labor intensity is high, operation
The big problem of security risk.
A kind of pot body closing end stamping die is provided, including the upper die and lower die and sealing element matched with end socket workpiece shapes,
The upper die and lower die and sealing element are ring-type；The upper mold includes stiffening ring and the pressure ring that is set to below the stiffening ring；
When punching press, the peripheral edge of end socket workpiece is located between upper die and lower die and sealing element, and is made under the action of the pressure ring
The peripheral edge of end socket workpiece is recessed to downwards in the open circles of the lower die to form one section of peviform curved-surface structure, the peviform
The lower surface of curved-surface structure compresses with the upper surface of sealing element and is bonded.
In above-mentioned technical proposal, the sealing element with a thickness of 2-4mm.
In above-mentioned technical proposal, the lower die, which is located on both sides of the edge opposite on central axis, is provided with positioning pin.
In above-mentioned technical proposal, the stiffening ring, which is located on both sides of the edge opposite on central axis, to be provided with and the positioning
Sell the location hole of cooperation.
In above-mentioned technical proposal, the stiffening ring is fixedly connected with the pressure ring.
The utility model has the beneficial effects that
A kind of pot body closing end stamping die and Sheet Metal Forming Technology of the utility model, wherein stamping die include and end socket workpiece
The upper mold and sealing element that shape matches, further include the lower die matched with end socket workpiece shapes, and upper die and lower die and sealing element are equal
For ring-type；Upper mold includes stiffening ring and the pressure ring that is set to below stiffening ring；When punching press, the peripheral edge sandwiched of end socket workpiece
The peripheral edge of end socket workpiece is set to be recessed to lower die downwards between upper die and lower die and sealing element, and under the action of pressure ring
Open circles in form one section of peviform curved-surface structure, the upper surface of the lower surface of the peviform curved-surface structure and sealing element compresses
Fitting.Compared with prior art, the utility model has the advantage that
(1) the utility model increases lower die, and improves to upper die structure, utilizes the pressure ring of upper mold and matching for lower die
Cooperation is used, and the peripheral edge of end socket workpiece is made to be recessed into downwards in the open circles of lower die to form one section of peviform curved surface knot
Structure, the curved-surface structure can offset the overwhelming majority due to the power that end socket workpiece slides trend to hydraulic pressure direction and generates, to change
It to be apt to mold force-bearing situation, has carried out punching press pot body closing end using the stamping die, operating pressure needed for making punching press substantially reduces,
(operating pressure of prior art stamping die needs about 25MPa, and the operating pressure of the utility model only needs about 16MPa), into
And reduce electric cost；
(3) since the pressure demand of stamping die reduces, then the performance requirement to sealing element is reduced, by the thickness of sealing element
Degree is reduced to 2-4mm by the about 12mm of the prior art, it can meets daily production and application；
(4) the utility model reduces the face for compressing end socket workpiece peripheral edge by the improvement to punching die structure
Product, and then the workpiece blank cost of raw material is reduced, so that the lightweight of mold body is obtained Yu Shixian, but also lifting, more mold exchange
When labor intensity reduce, improve working efficiency while due to being reduced to pressure demand, then it is hidden to effectively reduce production safety
Suffer from.
