Abstract

The utility model provides a novel automatic steel pipe flaring machine. A pull bar round steel (7) traverses through a first hollow iron disc (9), a ring-shaped oil cylinder (1), and a second hollow iron disc (8), and then is sleeved by a first hollow single-cone-shaped die (4) and a second hollow single-cone-shaped die (5). A hollow double inner inclining die (6) is connected to a spring and is sleeved between the first hollow single-cone-shaped die (4) and the second hollow single-cone-shaped die (5). Two ends of the pull bar round steel (7) are respectively fixed by a first nut (2) and a second nut (3).

Description

New automatic steel pipe pipe-expanding machine
Technical field
The utility model provides a kind of new automatic steel pipe pipe-expanding machine, is specifically related to the advance and retreat material technology in great dynamics cold extrusion enlarging technology and fast and convenient saving man-hour.
Background technology
Existing pipe-expanding machine is generally all bulky and the enlarging dynamics is little, and processing steel pipe caliber is little, and power consumption is big, and many with the workman.Given this, a kind of new automatic steel pipe pipe-expanding machine of special invention, it can carry out enlarging processing to the 80mm-1000mm thin-wall steel tube.This utility model electricity consumption is few, and workman and process time are saved in the enlarging great efforts, and be time saving and energy saving, and volume is little easy to use.
Summary of the invention
At the deficiency of existing pipe-expanding machine, the purpose of this utility model is to provide a kind of great dynamics enlarging system that has, the new automatic steel pipe pipe-expanding machine that Workpiece length is not limit.
For reaching goal of the invention, the utility model by the following technical solutions:
A kind of new automatic steel pipe pipe-expanding machine, pull bar round steel 7 is from the first cored iron disk 9, pass in annular cylinder 1, the second cored iron disk 8, put first hollow single prod cast tool 4 and second hollow single prod cast tool 5 again, hollow two interior tiltedly mould 6 usefulness spring adapter sleeves are between first hollow single prod cast tool 4 and second hollow single prod cast tool 5; Pull bar round steel 7 two are fixed with first nut 2, second nut 3 respectively.
Described annular cylinder 1 is the hydraulic jack of an intermediate hollow.
The tapered cylinder mould that described first hollow single prod cast tool 4 is intermediate hollows can be changed according to the steel pipe model of processing.
The tapered cylinder mould that described second hollow single prod cast tool 5 is intermediate hollows can be changed according to the steel pipe model of processing.
Described hollow two in tiltedly moulds 6 are hollow cylinder moulds by two inner conical, be divided into polyliths such as 6,8,10, can change according to the steel pipe model of processing.
Described pull bar round steel 7 is the threaded round steel in two, can change according to the steel pipe model of processing.
The described first cored iron disk 9 is circular steel of an intermediate hollow, can change according to the steel pipe model of processing.
The described first cored iron disk 8 is circular steel of an intermediate hollow, can change according to the steel pipe model of processing.
With respect to existing pipe-expanding machine, the new automatic steel pipe pipe-expanding machine that the utility model provides has following advantage:
(1), the new automatic steel pipe pipe-expanding machine that provides of the utility model uses hollow annular cylinder to do the technology that thrust realizes the internal expansion type enlarging, it comes transferring power by the pull bar round steel, and change is subjected to force direction, by first hollow single prod cast tool and the second hollow single prod cast tool of furthering, hollow two interior tiltedly mould is evenly outwards opened, thereby reach the enlarging purpose.Its mutual active force is offset at annular cylinder, does not so just need the outer steel grillage, greatly alleviates machine construction weight.
(2), the new automatic steel pipe pipe-expanding machine that provides of the utility model, its hollow two in tiltedly the mould design inner expanding force several times are increased, greatly improved the enlarging dynamics.、
(3), the new automatic steel pipe pipe-expanding machine that provides of the utility model is simple in structure, processes fast efficient height
The utility model uses 4 kilowatt motors to do power, can process steel pipe, and the electric system automatic control program is realized working time saving and energy saving less manpower automatically.
Description of drawings
Fig. 1 is new automatic steel pipe pipe-expanding machine structural representation
The 1-annular cylinder; 2-first nut, 3-second nut; 4-first hollow single prod cast tool; 5-second hollow single prod cast tool; The hollow two interior tiltedly moulds of 6-, 7-pull bar round steel, the 8-second cored iron disk, the 9-first cored iron disk.
The specific embodiment
As shown in Figure 1, a kind of new automatic steel pipe pipe-expanding machine, pull bar round steel 7 is from the first cored iron disk 9, pass in annular cylinder 1, the second cored iron disk 8, put first hollow single prod cast tool 4 and second hollow single prod cast tool 5 again, hollow two interior tiltedly mould 6 usefulness spring adapter sleeves are between first hollow single prod cast tool 4 and second hollow single prod cast tool 5; Pull bar round steel 7 two are fixed with first nut 2, second nut 3 respectively.
The concrete operations step is as follows:
The first step, earlier the workpiece steel pipe socket hollow two on the oblique mould 6.
In second step, annular cylinder 1 ejects to the right, drives pull bar round steel 7 by the first cored iron disk 9 and first nut 2 and moves right.Pull bar round steel 7 promotes first hollow single prod cast tool 4 by second nut 3 and moves right.First hollow single prod cast tool 4 when moving right and actionless second hollow single prod cast tool 5 actings in conjunction make hollow two in tiltedly mould 6 expand outwardly uniformly, thereby the bore of workpiece steel pipe is outside overlapped in expansion.
