Abstract
The utility model relates to a cold extrusion pipe bending die which comprises an upper die body, a lower die body and a die core. The cold extrusion pipe bending die is characterized in that a positioning boss is arranged at one end of the die core; step positioning notches are respectively formed on the upper and lower die bodies; and when the upper and lower die bodies are folded, the step positioning notches on the upper and lower die bodies are mutually connected to form a complete step positioning groove. The cold extrusion pipe bending die has the benefits that through the arrangement of the positioning boss at one end of the die core and the step positioning notches on the upper and lower die bodies, when the upper and lower die bodies are folded, the step positioning notches on the upper and lower die bodies are mutually connected to form the complete step positioning groove, the phenomena that pipe fittings are deformed when being extruded, and the thickness of the wall of a pipe is not uniform are effectively prevented, and product quality and output are improved.
Description
Technical field
The utility model relates to a kind of cold extrusion bend pipe mould.
Background technology
What each at present domestic pipe fitting factory all adopted when processing carbon steel, stainless steel elbow is the production technology of radially colding pressing; But we find core rod and the concrete circle control that forms of upper and lower mould in actual production process; Can not guarantee same circularity, cause the bending tube forming effect bad, pipe fitting is prone to produce concavo-convex; Increase the reparation amount, had a strong impact on the quality and the output of product.
The utility model content
The utility model technical problem to be solved provides a kind of cold extrusion bend pipe mould.
The technical scheme that the utility model solves the problems of the technologies described above is following:
A kind of cold extrusion bend pipe mould comprises that patrix is concrete, counterdie concrete, core rod, and said core rod one end is provided with positioning boss; Be respectively equipped with the notch cuttype positioning recess on the said upper and lower mold, when upper and lower mold closed up, the notch cuttype positioning recess on the said upper and lower mold was interconnected to a complete notch cuttype locating slot;
The complete notch cuttype locating slot that said notch cuttype locating slot is interconnected to form equates with the width of core rod termination positioning boss;
The height of said notch cuttype locating slot equates with the height of core rod termination positioning boss.
The beneficial effect of the utility model is: be respectively equipped with the notch cuttype positioning recess on positioning boss through the core rod termination and the upper and lower mold; When upper and lower mold closes up; Notch cuttype positioning recess on the said upper and lower mold is interconnected to a complete notch cuttype locating slot; Prevent phenomenons such as pipe fitting deforms, and pipe wall thickness is inhomogeneous effectively when extruding, improved the quality and the output of product.
Description of drawings
Fig. 1 and Fig. 2 are the structural representation of the utility model mould;
In the accompanying drawing, the list of parts of each label representative is following:
1, patrix is concrete, and 2, counterdie is concrete, 3, core rod, 4, locating slot, 5, positioning boss.
The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
The specific embodiment of the utility model bend pipe mould is:
A kind of cold extrusion bend pipe mould comprises that patrix is concrete 1, counterdie is concrete 2, core rod 3, and said core rod one end is provided with positioning boss 5; Be respectively equipped with the notch cuttype positioning recess on the said upper and lower mold, when upper and lower mold closed up, the notch cuttype positioning recess on the said upper and lower mold was interconnected to a complete notch cuttype locating slot 4;
The complete notch cuttype locating slot 4 that said notch cuttype locating slot is interconnected to form equates with the width of core rod termination positioning boss 5;
The height of said notch cuttype locating slot 4 equates with the height of core rod termination positioning boss 5.
The utility model when in use; The notch cuttype positioning recess that is respectively equipped with on positioning boss through the core rod termination and the upper and lower mold; When upper and lower mold closed up, the notch cuttype positioning recess on the said upper and lower mold was interconnected to a complete notch cuttype locating slot, had prevented that effectively pipe fitting from deforming when extruding; Phenomenons such as pipe wall thickness is inhomogeneous have improved the quality and the output of product.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
Claims (3)
1. a cold extrusion bend pipe mould comprises that patrix is concrete, counterdie concrete, core rod, and it is characterized in that: said core rod one end is provided with positioning boss; Be respectively equipped with the notch cuttype positioning recess on the said upper and lower mold, when upper and lower mold closed up, the notch cuttype positioning recess on the said upper and lower mold was interconnected to a complete notch cuttype locating slot.
