Description
Technical field
The present invention relates to bend pipe plug connector fields, and in particular to a kind of bend pipe plug gear chain type connector.
Background technique
Metallic thin wall hollow pipe fitting due to answering with advantages such as intensity height, light weight, easily molded, good appearances extensively
For fields such as Aeronautics and Astronautics, vehicle, ship and petrochemical industries.However, big radius-thickness ratio (D/t>50), small-bend radius (R/D<
2) thin-wall tube, since bend pipe inner tube wall is pressurized, is very easy to Instability wrinkling in numerical control bending forming；Outside tension is thinned,
It is easy to drawing crack；The resultant force of the two makes bend pipe section fasciation distort, or even collapses, therefore forming is difficult.
In order to reduce the bending forming defect of big radius-thickness ratio, thin-wall tube of small bend radius, need to install inside thin-wall tube
Plug provides internal support.Most common mandrel-type has ball-and-socket type plug and chain type plug.The plug pearl of ball-and-socket type plug
Ball and nest between there are larger gaps, there are biggish gap between the axis and chain piece of chain type plug, Shi Xin club because from
It naturally droops again, some specific position cannot be fixed on.And there is also gaps between plug and thin-wall tube, make plug to thin
The support accuracy of wall pipe is not high, to influence big radius-thickness ratio, the bending precision of thin-wall tube of small bend radius.
Summary of the invention
Object of the present invention is to naturally droop for the core club for solving existing plug because of self weight, some spy cannot be fixed on
Fixed position and existing plug is not high to the support accuracy of thin-wall tube influences big radius-thickness ratio, thin-wall tube of small bend radius bending essence
The problem of spending proposes that one kind has certain versatility, use and round tube bend in one direction plug are bent suitable for rectangular tube, supports essence
Spend high bend pipe plug gear chain type connector.
The purpose of the present invention is realized by following technical solution:
A kind of bend pipe plug gear chain type connector, which is characterized in that the gear chain type connector includes being respectively set
In each unilateral gear board group at connector both ends and pair of the no less than a pair being connected between two unilateral gear groups
Side gear board group；
The unilateral gear board group includes the unilateral gear plate of the arch door shape of a pair of opposing, setting a pair of unilateral
Long stop collar between gear plate and the axis through the connection unilateral gear plate and long stop collar.
The bilateral gear board group includes the bilateral gear plate of the endless track shape of a pair of opposing, is arranged in a pair
Short stop collar between bilateral gear plate and the axis through the connection bilateral gear plate and short stop collar；
Half nose circle of the unilateral gear plate is processed into tooth form, and two and half nose circles of the bilateral gear plate are all processed
At tooth form, two bilateral gear plates between the unilateral gear plate and adjacent bilateral gear plate, adjacent pass through tooth engagement,
And it is connected by connection sheet in the interior outside of engagement place.
Further, the long stop collar and short stop collar are the cylindrical body of Intermediate Gray through-hole.
Further, the connection sheet is also endless track shape, the connection sheet, unilateral gear plate and bilateral gear
Through-hole there are two opening up on the length direction of plate, between adjacent unilateral gear plate and bilateral gear plate, the axis is successively
Across connection sheet, unilateral gear plate or the bilateral gear plate in first outside, the connection sheet of first inside, short stop collar, the
The connection sheet of connection sheet, unilateral gear plate or bilateral gear plate, second outside on the inside of two is carried out through connection；Adjacent
Between bilateral gear plate, the axis is the connection sheet for sequentially passing through first outside, bilateral gear plate, first inside
Connection sheet, short stop collar, second inside connection sheet, bilateral gear plate, second outside connection sheet carry out through connection.
It further, is clearance fit between the axis and its part for running through connection.
Further, two through-holes on the unilateral gear plate be provided with respectively semi arch end center and non-semicircle
Two through-holes of the center at arc end, the bilateral gear plate and connection sheet are provided with the center at two semi arch ends.
Beneficial effects of the present invention are as follows:
(1) by the engagement of gear between unilateral gear plate and bilateral gear plate upper half knuckle-tooth, realize plug core ball and
Connection and constraint between mandrel, core ball and core ball, make core ball can be positioned at any position, improve plug to thin-wall tube
Support accuracy, so that the bending precision of thin-wall tube can be improved.
(2) it ensure that between unilateral gear plate and bilateral gear plate by the distance between 4 connection sheet connections and constraint
Meshing relation between two neighboring gear plate.
(3) gear chain type connector is modularized design, can according to actual needs, the gear of number needed for installing or length
Chain type connector.

Hole 32, third short stop collar 5, one of them 32, second bilateral gear of the second axis installation through-hole in the 7th connection sheet 3
First axle installation through-hole 12 where another half knuckle-tooth 11 of plate 2, one of them second axis installation in the 8th connection sheet 3
Through-hole 32.
According to the number or length of required gear chain type connector, second step operation is repeated.
Finally, the gear chain type connector 3 of installation outermost end.According to above-mentioned same method, if intermediate bilateral gear
Plate 2 is three pairs, then another the second axis installation through-hole 32, third being successively inserted in the 9th axis 6 in the tenth three pieces connection sheet 3
Another the second axis installation through-hole in 12, the 14th connection sheets 3 of first axle installation through-hole on a 1 center of circle of unilateral gear plate
32,32, the 4th unilateral gear plates of another the second axis installation through-hole in the 8th short 5, the 15th connection sheets 3 of stop collar
Another the second axis installation through-hole 32 in 12, the 16th connection sheets 3 of first axle installation through-hole on 1 center of circle.So that the 5th
Another half knuckle-tooth 11 of a bilateral gear plate 2 is engaged with the first axle installation through-hole 12 on 1 center of circle of third unilateral gear plate
It is connected；So that the first axle on another half knuckle-tooth 11 and the 4th 1 center of circle of unilateral gear plate of the 6th bilateral gear plate 2 is pacified
The engagement of through-hole 12 is filled to be connected.Then the first axle installation through-hole 12 by third unilateral gear plate 1 far from the center of circle is inserted in the tenth
On axis 6, then by second long stop collar 4 be packed into the tenth axis 6 on, then by the 4th unilateral gear plate 1 far from the center of circle first
Axis installation through-hole 12 is inserted on the tenth axis 6.
It will appreciated by the skilled person that being not used to limit the foregoing is merely the preferred embodiment of invention
System invention, although invention is described in detail referring to previous examples, for those skilled in the art, still
It can modify to the technical solution of aforementioned each case history or equivalent replacement of some of the technical features.It is all
