[0002] The collecting pipe is a pipe fitting or a pipe connector, which is a pipe fitting that draws a plurality of branch pipe holes at various positions on a main pipe. The prior art of the production device for drawing a metal collecting pipe is as "One" with the publication number ZL200820120735.8. A Special Equipment for Manifold Drawing Process", discloses a special equipment for manifold drawing process, the working surface of the mold is an irregular spherical body so as to reduce the resistance in the drawing process, but this mold will The extrusion deformation speed of the branch pipe hole is too fast during the drawing process, and the wall thickness thinning rate of the branch pipe is large. Moreover, due to the rebound phenomenon of the branch pipe material, the difference in the vertical and horizontal rebound of the branch pipe hole will cause the dimensional accuracy of the branch pipe hole. Difficult to control, needs to be reshaped after the branch pipe is formed

Abstract
The invention relates to a drawing mould special for metal manifolds, which comprises a drawing mould. The drawing module is an integrated drawing module consisting of an upper part, a middle part and a lower part; the upper part and the lower part of the integrated drawing module are cylinders, the middle part of the integrated drawing module is a conicalness, and the angle alpha of the conicalness of the middle part is 30-35 degrees. The drawing mould special for metal manifolds has the advantages of good drawing effect, low branch pipe thinning rate, energy saving and high dimensional precision.
Description
technical field [0001] The invention relates to a drawing die, in particular to a special drawing die for a metal collecting tube. Background technique [0002] The collecting pipe is a pipe fitting or a pipe connecting piece, which is a pipe fitting that draws a plurality of branch pipe holes at various positions on a main pipe. "Special Equipment for Manifold Drawing Process", which discloses a special equipment for manifold drawing process. The working surface of the mold is an irregular spherical body in order to reduce the resistance in the drawing process, but this mold will This leads to the problems that the extrusion deformation speed of the branch hole is too fast during the drawing process, and the thinning rate of the branch pipe wall thickness is large. Moreover, due to the rebound phenomenon of the branch pipe material, the different rebound amount of the branch pipe hole longitudinally and laterally will cause the dimensional accuracy of the branch pipe hole. ...
