Embodiment
The present invention is further elaborated and illustrated with reference to specific embodiment and Figure of description：Please refer to Fig.1, scheme
2nd, Fig. 3 and Fig. 4, a kind of double water route stamping dies, including board gland 13, upper mounted plate 14, bottom plate 17, cope plate
18th, lower template 21 and stretching head 24, board gland 13 are fixed on 14 top of upper mounted plate, through hole are equipped among cope plate 18,
18 screw of cope plate is fixed on 14 lower part of upper mounted plate, and stretching head 24 is arranged in 18 through hole of cope plate and is fixed on upper mounted plate 14
Lower part, lower template 21 are fixed on 17 top of bottom plate, and lower template 21 is arranged on immediately below cope plate 18, and upper mounted plate 14 4 is angular
Guide post 15 is had, 17 4 jiaos of bottom plate is equipped with guide sleeve 16 upwards, and guide post 15 can slide up and down in guide sleeve 16, pass through guide post
15 and guide sleeve 16 carry out the guiding of open mold, upper mounted plate 14 and upper stretching head 24 are internally provided with the first thermal cycle water route 11 and the
One SAPMAC method water route 12, lower template 21 are internally provided with the second thermal cycle water route 20 and the second thermal cycle water route 19,24 He of stretching head
Offer die cavity between lower template 21, forcing press be fixed on by board gland 13, by forcing press drive upper mounted plate 14,
Stretching head 24 and cope plate 18 move down, and are closed stretching head 24 and 21 die cavity of lower template, pass through the first thermal cycle water route 11
Heated with the second thermal cycle water route 20 to stretching head 24 and 21 die cavity of lower template, the sheeting in die cavity is softened, can
Destruction to sheeting when reducing punching press, the generation for phenomena such as preventing uniaxial direct tensile first 24 from thrusting sheeting, thin slice into
After type, cooled down by the first SAPMAC method water route 12 and the second thermal cycle water route 19 to stretching head 24 and lower template 21, by thin slice temperature
Degree is reduced to below room temperature, and the internal stress for making thin slice be produced by deformation and heating, discharges during cooling.
First SAPMAC method water route 12 is arranged on below the first thermal cycle water route 11 inside stretching head 24, the second SAPMAC method water route
19 are arranged on above the second thermal cycle water route 20 inside the lower template 21, make in heating process, because of the first thermal cycle water route 11 and the
There is certain distance in two thermal cycle water routes 20 with die cavity, can be more uniformly distributed stretching head 24 and the heated of the die cavity of lower template 21, together
When the first SAPMAC method water route 12 and the second SAPMAC method water route 19 it is nearer from die cavity, accelerate the cooling of die cavity, accelerate sheeting
Shaping.
The lower section of cope plate 18 offers location hole, and the above-mentioned top of lower template 21 is equipped with positioning pin, is played in clamping process
Positioning action.
Stretching head 24 is equipped with anti-with the interface in 14 first SAPMAC method water route 12 of upper mounted plate and the first thermal cycle water route 11
Hydrosphere 23, increases the waterway seal between stretching head 24 and upper mounted plate 14.
Cope plate 18 is equipped with elastic component 22 with fixed plate screw connection, protrudes cope plate 18 by 22 elastic force of elastic component
Stretching head 24, elastic component 22 is spring herein, in clamping process, first passes through cope plate 18 and lower template 21 is positioned, keep away
Exempt from stretching head 24 and the die cavity of lower template 21 does not align.
First thermal cycle water route 11 and the first SAPMAC method water route 12 are respectively made of and by importing and exporting pipeline a plurality of aquaporin
Connect, the first thermal cycle water route 11 and the first SAPMAC method water route 12 are in concave shape, and the first thermal cycle water route 11 is followed arranged on the second heat
In 19 groove of ring water route, make the first thermal cycle water route 11 and the first SAPMAC method water route 12 non-intersect, and a plurality of pipeline makes first
11 and first SAPMAC method water route 12 of thermal cycle water route and 24 contact surface bigger of stretching head, make the die cavity on stretching head 24 add hot and cold
But evenly and more rapidly.
Second thermal cycle water route 20 and the second thermal cycle water route 19 are respectively made of and by importing and exporting pipeline a plurality of aquaporin
Connect, the second thermal cycle water route 20 and the second thermal cycle water route 19 are in respectively bamboo row-like arrangement, and bamboo row-like arrangement makes the second thermal cycle
20 and second thermal cycle water route 19 of water route and 21 contact surface bigger of lower template, be die cavity heating in template and cooling evenly and
More rapidly.
First thermal cycle water route 11 inlet and outlet are arranged on 14 the same side of upper mounted plate, and the second thermal cycle water route 20 inlet and outlet are arranged on
21 the same side of lower template.
First SAPMAC method water route 12 inlet and outlet are arranged on the opposite both sides of upper mounted plate 14, and the second thermal cycle water route 19 is imported and exported
Set the opposite both sides of template 21.
First thermal cycle water route 11 and the second thermal cycle water route 20 lead to hot steam, the first SAPMAC method water route 12 and second
Thermal cycle water route 19 leads to cold air, makes the heating of die cavity and cools down more rapidly.
In such scheme, board gland 13 is fixed on forcing press, sheeting is positioned over to the die cavity of lower template 21
Interior, forcing press drives stretching head 24 to press down, and the first thermal cycle water route 11 and the second thermal cycle water route 20 is connected, to stretching head 24
Heated with the die cavity of lower template 21, make sheet soft, continuing to press on stretching head 24 by forcing press moves down, and passes through stretching head
24 and lower template 21 die cavity by slice forming, stop the heating in the first thermal cycle water route 11 and the second thermal cycle water route 20, connect
Logical first SAPMAC method water route 12 and the second thermal cycle water route 19, cool down to stretching head 24 and the die cavity of lower template 21, drop thin slice
The inside bending stress of temperature and releasable material, after thin slice cooling, stops the first SAPMAC method water route 12 and the second thermal cycle water route
19 cooling, forcing press drive stretching head 24 and cope plate 18 to move up, and take out the thin slice after shaping, complete a punching press, thin slice
The internal stress produced by deformation in die cavity cool down when discharge, take out the thin slice finished product after mould deformation it is small, so as to carry
The formed precision of high sheeting.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected
The limitation of scope is protected, although being explained with reference to preferred embodiment to the present invention, those of ordinary skill in the art should
Work as understanding, can be to technical scheme technical scheme is modified or replaced equivalently, without departing from the reality of technical solution of the present invention
Matter and scope.
