Diameter.By change lower die adjustment ring height (i.e. change lower die movable matrix realized with lower die adjustment ring distance l3) at
The limitation that upper mold movable matrix is displaced during shape.Lower template is the cylindrical part with flange, and periphery and lower die are living
Dynamic cavity plate is clearance fit.The depth being screwed by adjusting guide rod adjusting screw adjusts the opposite position of guide rod middle cone
It sets.The second lower die spring lever and lower die adjustment screw are evenly arranged on lower template flange, quantity needs to set according to forming
Meter.It is connected between lower die movable matrix and lower template by the second lower die spring lever.The second lower die is covered on second lower die spring lever
Spring and the second lower die spring adjust gasket, are realized by changing the height of the second lower die spring adjustment gasket to the second lower die
The adjustment of the distance between spring load, lower die movable matrix flange and lower template flange L4.Push-down head is located at lower template cylinder
On the end face in face, push-down head is open circles column, and internal diameter is slightly larger than guide rod taper end outer diameter, and outer diameter is less than in lower die movable matrix
Bore dia and 2 times of pipe wall thickness.Push-down head head uses conical surface, and cone angle needs to design according to forming.It is adjusted in lower die
Lower die adjusting nut and lower die locking nut are provided on screw rod, by adjusting lower die movable matrix flange and lower template flange it
Between distance L4 and lower die adjusting nut and cope plate distance l4 realize the control of the compression distance to push-down head in forming.
The advantage of the invention is that the following:
(1) forming for being completed ripple using movable matrix and pressure head cooperation in forming process, is reduced needed for forming
The pressure of granule medium, while also avoiding lacking due to loading the formings such as generated pipe Compressional buckling in original blank end
It falls into, reduces the control difficulty of technological parameter.
(2) forming that can be realized simultaneously two ripples in a loading procedure, improves forming efficiency.
(3) it only needs to load cope plate in entire forming, it is no longer necessary to which other external applied loads are reduced to forming
The dependence of equipment.
