Description

Steel pipe drawing adjust automatically plug
Technical field
The utility model relates to a kind of steel pipe drawing plugs.
Background technique
Existing drawbench, general composition are made of plug, outer mould base, draw trolley and other corresponding corollary equipments; Cold-drawing machine mandrel, external mold centre bore, fixture are typically all that careful design is fixed, primarily to keeping drawing process same On axle center, so that drawing process is stable, do not generate offset, the equal uniform force of Steel pipe mould etc..The steel tube performance pulled out in this way Stress that is good, generating is small and die life is high, also helpful for wall unevenness control, simultaneously because bending and distortion subtract It is small, there is good help for performance, the aligning etc. of heat treatment.
It due to the bending that can be generated after plug prolonged use, and is difficult to correct, renewal cost is also high.Die holder is due to being Fixed, and adjustment difficulty is big, is generally difficult to adjust.Draw trolley only serves draw, cannot adjust to steel pipe stress It is whole, therefore in the actual process, bending and distortion occur often, greatly reduce efficiency and cost, and the performance after heat treatment It is unstable.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of steel pipe drawings for guaranteeing steel pipe drawing quality to use certainly Dynamic adjustment plug.
In order to solve the above technical problems, the technology employed by the present utility model is steel pipe drawing adjust automatically core The base shaft in plug mounting base is arranged in including one end in stick, and base shaft end is removably equipped with connecting rod, and connection boom end is in ball Planar, connection boom end are movably equipped with molding internal model, and molding internal model is equipped with connection through-hole, the separate link block of connection through-hole End is equipped with spherical groove, and the connection through-hole that locating rod passes through molding internal model is detachably connected with connecting rod, and locating rod is equipped with There are the gap of 1-2mm, molding in the guide pad matched with spherical groove, locating rod and molding internal model between the hole wall of connection through-hole Internal model is equipped with the tube forming guiding angle surface of arc-shaped far from the end periphery of connecting rod, and intermode is even in the connecting rod and molding The dome shape end outer sheath of extension bar is equipped with reset spring.
As a preferred solution, one end that the connecting rod is connected with base shaft is equipped with threaded rod, in the base shaft Equipped with the threaded hole matched.
As a preferred solution, the force section that section is in regular hexagon is equipped in the connecting rod by threaded rod.
As a preferred solution, the molding internal model is equipped with close to one end of connecting rod is embedded in for reset spring Mounting groove also is provided with the mounting groove being embedded in for reset spring in the connecting rod.
As a preferred solution, the molding internal model also is provided with the tubing of arc-shaped close to the end periphery of connecting rod Guiding angle surface is formed, the molding internal model is far from the mounting groove for also being provided with being embedded in for reset spring on one end of connecting rod.
The beneficial effects of the utility model are: connection boom end is in ball since base shaft end is removably equipped with connecting rod Planar, connection boom end are movably equipped with molding internal model, and molding internal model is equipped with connection through-hole, the separate link block of connection through-hole End is equipped with spherical groove, and the connection through-hole that locating rod passes through molding internal model is detachably connected with connecting rod, and locating rod is equipped with There are the gap of 1-2mm, molding in the guide pad matched with spherical groove, locating rod and molding internal model between the hole wall of connection through-hole Internal model is equipped with the tube forming guiding angle surface of arc-shaped far from the end periphery of connecting rod, and intermode is even in the connecting rod and molding The dome shape end outer sheath of extension bar is equipped with reset spring, so that plug position can be with adjust automatically, so that the steel of drawing Thickness of pipe wall is uniform, avoids heat-treated steel pipe from generating bending deformation, ensure that tube quality after drawing.
Since one end that connecting rod is connected with base shaft is equipped with threaded rod, base shaft is equipped with the threaded hole matched, convenient The installation of connecting rod.
Due to being equipped with the force section that section is in regular hexagon in connecting rod by threaded rod, so that the installation of connecting rod is more It is convenient.
Since molding internal model is equipped with the mounting groove that is embedded in for reset spring close to one end of connecting rod, in the connecting rod It also is provided with the mounting groove being embedded in for reset spring, facilitates the installation of reset spring.
Since molding internal model also is provided with close to the end periphery of connecting rod the tube forming guiding angle surface of arc-shaped, internal model is formed The mounting groove being embedded in for reset spring also is provided on one end far from connecting rod, so that being not necessarily to respectively just when molding internal model installation Instead, to improve installation speed.
