Abstract
The utility model relates to a cold drawing mould is managed in side, the mould main part is equipped with draws the through -hole, the advancing direction of edge side pipe should draw the through -hole in order including the entry, draw area, calibrating strap and export, enter the mouth and draw the cambered surface of taking smooth transition as an organic whole, enter the mouth and draw the radial cross section in area and the cross -section phase -match of square pipe, the curved surface radius of entry is less than the curved surface radius of drawing the area, the square bore of calibrating strap remains unchanged and the length of calibrating strap is lighter than the length of drawing the area, and the export angle is 40~60. The utility model discloses pipe drawing operation in the side of messenger is more level and smooth smooth and easy, helps obtaining better surface quality's square pipe, the production qualification rate that managed the side of improvementing.
Description
Technical field
This utility model belongs to cold drawing steel tube manufacturing technology field, is specifically related to a kind of square tube cold drawing die.
Background technology
As the cold process of the steel for mechanical structure pipes such as carbon steel, alloy steel or stainless steel, known to have the drawing processing method carried out by drawbench and the rolling processing method carried out by Pierre's form milling train.Wherein, drawbench the drawing processing method carried out, compared with the rolling processing method carried out by Pierre's form bundle machine, cold working steel pipe can be manufactured expeditiously.
The production procedure of cold drawing steel tube is generally heat treatment-pickling-phosphatization-saponification-cold-drawn-annealing, and cold-drawn operation is to ensure that square tube obtains the key link of given size, drawing mould proportioning problem to be considered during drawing, in addition it is also necessary to use the drawing mould of appropriate design.The structure of mould drawing deformation accent designs the surface quality that more direct relation section bar is last.
Utility model content
Technical problem to be solved in the utility model is to provide the mould of a kind of Cold drawing square pipe for above-mentioned prior art, it is ensured that the surface quality of every square tube, improves qualification rate.
The technical scheme in the invention for solving the above technical problem is: a kind of square tube cold drawing die, die main body is provided with drawing through hole, this drawing through hole of direct of travel along square tube sequentially includes entrance, drawing band, calibrating strap and outlet, described entrance and drawing band seamlessly transit the cambered surface being integrated, the radial section of entrance and drawing band matches with the cross section of square tube, the subsequent corrosion of entrance is less than the subsequent corrosion of drawing band, the square bore of described calibrating strap keeps constant and calibrating strap length to be less than the length of drawing band, and exit angle is 40～60 °.
Preferably, exit angle is 45 °.
Compared with prior art, the utility model has the advantage of: provide a kind of square tube cold drawing die, whole drawing through hole smooth, contribute to obtaining the square tube of more preferable surface quality, improve the production qualification rate of square tube.
Accompanying drawing explanation
Fig. 1 is the structural representation of drawing through hole in this utility model embodiment；
Fig. 2 is the sectional view of cold drawing die in this utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As shown in Figure 1, 2, square tube cold drawing die in the present embodiment, die main body is provided with drawing through hole A, this drawing through hole of direct of travel along square tube sequentially includes entrance 1, drawing band 2, calibrating strap 3 and outlet 4, entrance 1 and drawing band 2 seamlessly transit the cambered surface being integrated, the radial section of entrance and drawing band matches with the cross section of square tube, the subsequent corrosion of entrance 1 is 10mm, the subsequent corrosion of drawing band 2 is 180mm, the square bore of calibrating strap 3 keeps the constant and a length of 50mm of calibrating strap, less than the length of drawing band 2, exit angle is 45 °.
The cold drawing die of said structure makes square tube drawing operate more smooth, contributes to obtaining the square tube of more preferable surface quality, improves the production qualification rate of square tube.
In addition to the implementation, this utility model also includes the technical scheme that other embodiments, all employing equivalents or equivalence substitute mode are formed, within all should falling into this utility model scope of the claims.
Claims (2)
1. a square tube cold drawing die, die main body is provided with drawing through hole, this drawing through hole of direct of travel along square tube sequentially includes entrance, drawing band, calibrating strap and outlet, it is characterized in that: described entrance and drawing band seamlessly transit the cambered surface being integrated, the radial section of entrance and drawing band matches with the cross section of square tube, the subsequent corrosion of entrance is less than the subsequent corrosion of drawing band, the square bore of described calibrating strap keeps constant and calibrating strap length to be less than the length of drawing band, and exit angle is 40～60 °.
Square tube cold drawing die the most according to claim 1, it is characterised in that: exit angle is 45 °.
