Abstract
The utility model discloses an external screw thread cold extruding forming device which at least comprises one top cover, a bottom cover, a plurality of cylinders and three groups of cylindrical die rolls, wherein the plurality of cylinders are used for fixing the top cover and the bottom cover, the three groups of the cylindrical die rolls are rotatably connected between the top cover and the bottom cover, and a forming space is formed among the three groups of the cylindrical die rolls. The external screw thread cold extruding forming device is capable of reducing labor cost and material cost.
Description
Technical field
The utility model relates to the cold extrusion shaped equipment of a kind of external screw thread.
Background technology
The mode of existing external gear moulding is machining, at first, the raw material of Production Example such as column, then adopt cutter that these raw material are processed, processing also molds the external gear that needs, the problem of its existence is apparent: at first, the precision of the external gear that the means by machining obtain is difficult to guarantee, depend on especially artificial judgment and workman's familiarity, and consummate workman's cost is generally higher, also increases product cost from the another one angle, be more in addition, mechanical processing process is difficult to avoid the generation of waste material, and this also causes the further raising of processing cost, demands urgently improving.
The utility model content
For the problem that prior art exists, the purpose of this utility model is to propose the cold extrusion shaped equipment of a kind of external screw thread, can reduce cost of labor and material cost.
For reaching this purpose, the utility model by the following technical solutions:
The cold extrusion shaped equipment of a kind of external screw thread, this equipment comprises at least
One top cover;
One bottom;
The cylinder of some fixing described top covers and described bottom;
Be rotatably connected on three groups of cylindrical die rolls between described top cover and the described bottom;
Form molding space between three groups of described cylindrical die rolls.
Also comprise and be rotationally connected turning of described bottom;
Described the first gear of turning of axial restraint;
Described the first gear of interlock and axial off-centre are fixed the second gear of one group of described cylindrical die roll.
Offer the groove of spacing described cylindrical die roll on the described bottom, the cross-sectional area of described groove is greater than the cross-sectional area of described cylindrical die roll.
Described top cover is offered the through hole that is communicated with described molding space.
Comprise three groups of described cylinders.
Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:
The utility model adopts the mode moulding external screw thread of colding pressing, thereby can not produce waste material, can reduce cost and drop into, because the precision of external screw thread final molding relies on three cylindrical die rolls to hold, can not cause Product Precision not high because of artificial reason, thereby can reduce cost of labor.

The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment:
Embodiment 1
Propose the cold extrusion shaped equipment of a kind of external screw thread, this equipment comprises a top cover 1 at least; One bottom 4; The cylinder 2 of some fixed roofs 1 and bottom 4; Be rotatably connected on the three groups of cylindrical die rolls 31,32,33 between top cover 1 and the bottom 4; Form molding space between three groups of cylindrical die rolls 3.Also comprise be rotationally connected bottom 4 turn 5; Turn the first gear 6 of 5 of axial restraint; Interlock the first gear 6 and axial off-centre are fixed the second gear 7 of one group of cylindrical die roll 3.Offer the groove 41 of spacing cylindrical die roll 3 on the bottom 4, the cross-sectional area of groove 41 is greater than the cross-sectional area of cylindrical die roll 3.Top cover 1 is offered the through hole 11 that is communicated with molding space.Comprise three groups of cylinders 21,22,23.
To stretch into molding space by through hole 11 for processing parts 8, and make between part 8 and three groups of cylindrical die rolls 3 relative motion occurs, thereby make part 8 test pencil generation deformation, form the external screw thread that needs.
The above; it only is the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, all should be encompassed within the protection domain of the present utility model.
