As the preferred scheme of one, upper bolster is provided with two pieces of location-plates paralleled between two upper end modules, upper intermediate module comprises the some patrix inserts be arranged on upper bolster between location-plate, is arranged with some adjustment keys between location-plate and patrix insert.
As the preferred scheme of one, lower intermediate module is respectively equipped with binder balance weight perpendicular to the both sides of tubing, and on upper bolster, relevant position is also provided with binder balance weight; Upper bolster is provided with some binder balance weights on upper end module side, die shoe is also provided with binder balance weight in corresponding position.
As the preferred scheme of one, upper bolster is respectively equipped with the stroke cover plate of restriction upper end module stroke in upper end module perpendicular to the both sides of tubing, and module both sides, upper end are provided with corresponding limited block; On die shoe under lower intermediate module is respectively equipped with restriction perpendicular to the both sides of tubing the stroke cover plate of intermediate module stroke, lower intermediate module both sides are provided with corresponding limited block.
As the preferred scheme of one, upper end module surrounding is respectively equipped with wear-resistant block, and lower intermediate module surrounding is respectively equipped with wearing plate.
The invention has the beneficial effects as follows: because upper end module activities is arranged on upper bolster, the movement travel of upper end module be shaping after the axis in tubing stage casing add 5-20cm to the distance of tube end section axis, when upper bolster moves down, upper end module can contact compression pipe end in advance with bottom module, and the location of the section of being beneficial to tubing also prevents bend at end place to be out of shape; Coordinating of upper intermediate module tubing stage casing is supported owing to have employed movable lower intermediate module with fixing, and the movement travel of lower intermediate module be shaping after the axis in tubing stage casing to the distance of tube end section axis, thus make the pipe deformations Minimum Energy after punch forming reach processing request.
Because upper intermediate module comprises the some patrix inserts be arranged on upper bolster between location-plate, the use amount of the high strength steel needed for pattern can be reduced to like this thus reduce die cost, and being convenient to processing; Owing to being arranged with some adjustment keys between location-plate and patrix insert, by suitable adjustment key, each patrix insert can be installed accurately quickly and easily.
Owing to being provided with binder balance weight, by selecting highly suitable binder balance weight to control the tightness of upper molding compound.
The arranging of stroke cover plate can ensure lower intermediate module or upper end module can not displacement excessive.
