Groove, intermediate dynamic model are made of two pieces of mutually independent dynamic model monomers 3, and two dynamic model monomers 3 are placed in the groove of lower cavity die 2, and two
The opposite side of dynamic model monomer 3 is arc surface 301, and two arc surfaces 301 can constitute the great circle cambered surface that central angle is more than 180 °
305,305 radius of the great circle cambered surface is sheet member thickness, the lower cavity die 2 with 1 lower face arc surface of upper male mould, 101 semidiameter
The two opposite side walls of groove are respectively equipped with a through-hole 6, and a bolt 4 is equipped in the through-hole 6, and bolt 4 is passed through by 2 outside of lower cavity die
Through-hole 6 is fixedly connected with 3 outside of dynamic model monomer of respective side, a bullet is equipped between 2 lateral surface of 4, the bolt and lower cavity die
Spring 5.
In the present embodiment, one is equipped at the minimum point of 1 lower face arc surface 101 of the upper male mould to be recessed upwards to keep away
Allow the groove 103 of copper pipe in sheet member, 101 top both sides of arc surface are respectively equipped with an acclivitous inclined-plane 102.
In the present embodiment, 3 upper side of dynamic model monomer be by the outside of dynamic model monomer 3 inclined inclined-plane 303 inwardly,
The inclined-plane 303 is identical as the gradient on 1 arc surface both sides inclined-plane 102 of upper male mould.
In the present embodiment, the lateral surface of the dynamic model monomer 3 is vertical plane 302, and outer bottom is horizontal plane 304, described
Two medial surfaces of lower cavity die 2 are the inclined-plane 201 being inclined outwardly, and 2 inner bottom surface of lower cavity die is horizontal plane 202.
In the present embodiment, the included angle A of 2 liang of medial surfaces of the lower cavity die and vertical plane is gone to the bottom at least more than dynamic model monomer 3
The included angle B of arc surface peak tangent line and vertical direction when face is in horizontality.
In the present embodiment, the through-hole of 2 groove two side of the lower cavity die is long kidney-shaped hole 6, and 5 one sections of the spring is against
2 lateral surface of lower cavity die, the other end are against the lower face of 4, bolt.
The operation principle of above structure is as follows：
Under non-punching press state, the spring 5 between 2 lateral surface of bolt 4 and lower cavity die is in compressive state, in 5 bullet of spring
Under the action of power, bolt 4 pulls out the dynamic model monomer 3 of connection fixed thereto, and hinge of the dynamic model monomer 3 around lower section rotates,
To make intermediate dynamic model be flared out, and bolt 4 is oblique in the first inclination of heeling condition bolt 4 in long kidney-shaped hole 6 at this time
Downwards.
Aluminum alloy thin plate to be processed is placed on the upper surface of lower cavity die 2, and upper male mould 1 moves downward, to the aluminium of lower section
Latten part carries out punching press, and during 1 downward punching press of upper male mould, dynamic model monomer 3 can be made by the pressure of sheet member
Two dynamic model monomers 3 respectively overcome the pulling force of bolt 4 and rotate in opposite directions, until intermediate dynamic model arc surface is bonded with sheet member, complete
Punching press to sheet member.
During dynamic model monomer 3 rotates in opposite directions, bolt 4, which is pulled, gradually to be tended to be horizontal, and spring 5 is received
It is gradually compressed to 4 pressure of 2 lateral surface of lower cavity die and bolt.
When being molded, upper male mould 1 moves upwards, and is gradually reduced the pressure to dynamic model monomer 3 during the motion, and two
Dynamic model monomer 3 can be rotated backward gradually under the action of 5 elastic force of spring in the state outwardly opened.Due to 2 liang of insides of lower cavity die
The angle of face and vertical plane therefore works as dynamic model at least more than the angle of 3 arc surface peak tangent line and vertical direction of dynamic model monomer
When 3 lateral surface of monomer is bonded with 2 medial surface of lower cavity die, the circular arc of machine-shaping can take out out of intermediate dynamic model.
For the absorber plate used on solar heat-collection plate, welding medium can be followed on plate before carrying out punch process
Ring copper pipe M, and copper pipe M is needed to be located at the medial surface of absorber plate circular arc, therefore opened up at the minimum point of 1 arc surface of upper male mould
Groove, to avoid the copper pipe M being welded on plate in punching course.
