Abstract
The utility model relates to a core rod assembled trolley for cold-drawn steel pipes. The core rod assembled trolley comprises a trolley body with a core rod inside, wherein one end of the core rod is provided with a thrusting machine, the other end of the core rod is provided with a steel pipe in an adaptive manner, a plurality of bearings adaptive to the core rod are arranged at two sides of the inside of the trolley body, and the core rod is driven to rotate along the inner wall of the trolley body by the bearings. The core rod can be prevented from being fractured, the cost is lowered, and the efficiency is improved.
Description
Technical field
The utility model relates to a kind of dress mandrel trolley, is specifically related to a kind of cold-drawn and has the dress mandrel trolley that inner thread steel pipe is used.
Background technology
When drawbench is produced inner thread steel pipe, when plug carries out drawing through steel pipe, often because twisting plug, screw thread rotation ruptures.The utility model is provided with the dolly of several bearings by inside, make the Mandrel Rotating along with the precession of screw thread, and can bear larger torsion.When producing inner thread steel pipe, easy and simple to handle, cost-saving.
Summary of the invention
The dress mandrel trolley that provides a kind of cold drawing steel tube to use is provided the purpose of this utility model, and inside is provided with the dolly of several bearings, makes the Mandrel Rotating along with the precession of screw thread, when producing inner thread steel pipe, easy and simple to handle, cost-saving.
For achieving the above object, the dress mandrel trolley that the utility model provides a kind of cold drawing steel tube to use, comprises that inside is equipped with the vehicle body of plug, and one end of described plug is provided with thrust machine, and the other end is provided with suitable with it steel pipe; Described interior of body both sides are respectively equipped with the suitable bearing of several and plug, and described bearing makes plug be rotated along vehicle body inwall.Prevent that plug from rupturing, cost-saving, raise the efficiency.
The beneficial effects of the utility model are: easy and simple to handle, simple in structure, raise the efficiency, and cost-saving.
Accompanying drawing explanation
Fig. 1 represents structural representation of the present utility model;
Drawing reference numeral: 1-vehicle body, 2-plug, 3-bearing, 4-thrust machine, 5-steel pipe.
The specific embodiment
In order to deepen, to understanding of the present utility model, below in conjunction with drawings and Examples, the utility model to be described in further detail.
By reference to the accompanying drawings 1, the utility model proposes the dress mandrel trolley that a kind of cold drawing steel tube is used, comprise that inside is equipped with the vehicle body 1 of plug 2, one end of described plug 2 is provided with thrust machine 4, and the other end is provided with suitable with it steel pipe 5; The inner both sides of described vehicle body 1 be respectively equipped with two with the suitable bearing 3 of plug 2, described bearing 3 makes plug 2 be rotated along vehicle body 1 inwall.
When work, thrust machine 4 pushes plug 2 in steel pipe 5, and bearing 3 makes plug 2 be rotated along vehicle body 1 inwall, plug 2, with the internal thread precession of steel pipe 5 inwalls, can bear larger torsion, prevents that plug from rupturing, simple in structure, raise the efficiency, cost-saving.
