Abstract
The utility model relates to an elbow pipe forming die which is a cylinder driven by a driving mechanism to rotate. The external circle of the cylinder is processed into a spiral groove corresponding to a pipe blank, and the lower end of the cylinder is provided with a fixture for fixing the end of the pipe blank. The elbow pipe forming die provided by the utility model can form a plurality of circular pipes once by utilizing the spiral motion of an elbow pipe mechanism, so that the production efficiency is greatly enhanced.
Description
Technical field
The utility model relates to a kind of bent pipe mold, and it is applied in the moulding that straight tube is made into round tubes such as grading ring specifically.
Background technology
In a lot of occasions, need utilize the large diameter pipe circle, such as the anticorona ring on the power circuit.Traditional anticorona ring is general to adopt a plurality of circular arc ring weldings to form, and making whole poor dimensional precision influences anti-corona effect.In addition, this anticorona ring is made complicated, needs multiple-pass weld.
Application number is that 2009100284318 patent provides a kind of 360 ° of bending machines for this reason, and it carries out bending to pipe end when straight tube is sent to, makes straight tube according to the center of circle, the radius generation plastic deformation set.In order to make canal curvature become complete 360 °, it pinches rod group, guide roller one, guide roller two and tilts respectively, forms spiral trend, makes straight tube when carrying out the circumference plastic deformation, and the spirality distortion also takes place.Behind the disconnected pipe, with tube head press down, dock with fracture full circle, the words of welding have only a weld seam.Improve the precision of Guan Yuan greatly, strengthened anti-corona effect.
360 ° of bending machines that above-mentioned patent application provides once can only pipe of moulding; Treating needs earlier disconnected pipe just can carry out the moulding of next pipe after the shaping round tube, and its processing lacks continuity, and production efficiency is low; Can not satisfy large-scale production demand, need further to improve.
The utility model content
The utility model is to above-mentioned defective, and it is a kind of when guaranteeing the pipe quality that purpose is to provide, a kind of bent pipe mold of further enhancing productivity.
The technical scheme that the utility model adopted for this reason is: the utility model is the cylindrical drum that rotated by drive mechanism, and the cylindrical drum cylindrical is processed into the helicla flute corresponding with pipe, and the fixedly anchor clamps of pipe end are established in the cylindrical drum lower end.
The bending machine of the utility model utilizes the screw of pipe bending mechanism, but a plurality of pipes of disposal molding have improved production efficiency greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the A-A view of Fig. 1.
1 is that anchor clamps, 2 are cylindrical drum among the figure.
The specific embodiment
The utility model is the cylindrical drum 2 that rotated by drive mechanism, and cylindrical drum 2 cylindricals are processed into the helicla flute corresponding with pipe, and the fixedly anchor clamps 1 of pipe end are established in cylindrical drum 2 lower ends.
The pipe 2 of the utility model becomes pipe at cylindrical drum 2 upper edge helicla flute screw spiral formings, then behind the spiral forming anchor clamps 1 dismounting, pipe outwards singly goes out under the effect of self metallic elastic power, breaks away from cylindrical drum 2, and takes out; Last according to circumstances need the pipe that take out be cut, subsequent treatment such as polishing, form required product.
Claims (1)
1. bent pipe mold is characterized in that, is the cylindrical drum that rotated by drive mechanism, and the cylindrical drum cylindrical is processed into the helicla flute corresponding with pipe, and the fixedly anchor clamps of pipe end are established in the cylindrical drum lower end.
