Description
Technical field
The utility model is related to steel pipe anchorage technical field, especially a kind of Tube Drawing anchorage.
Background technology
In cold-drawing seamless tube technique, subtract wall expanding and subtract the processing of wall tube reducing is divided into steel pipe, two kinds plus
The main distinction of work is to subtract the expanding processing method of wall, and wall is expanding, and inner disc is born more during subtracting wall subtract
Big resistance of deformation, it is on the contrary then be external disk.Subtract the referred to outer diameter of steel pipes size of wall of wall, expanding diameter institute in the utility model
Finger is the internal diameter size of steel pipe.
Cold-drawn anchorage is formed multigroup corresponding including being an inner disc and an external disk between inner disc outer wall and external disk inner wall
Reducing sizing band for carrying out subtracting wall, expanding processing to steel pipe, during Tube Drawing, inner disc is needed through a branch
Support member fixes operating position, keeps it in reducing sizing band, and wherein support element includes pull rod and nut gasket component, existing
There is the inner disc in technology during drawing is processed, mainly coordinate with nut gasket component, for carrying drawing processing
The pulling capacity generated in the process uses common cylinder since high-carbon-chromium bearing steel steel pipe is big in drawing deformation process resistance of deformation
When shape inner disc drawing, draw elongation percentage is slightly larger than just will produce steel pipe fracture, simultaneously because nut gasket component and inner disc are matched
Conjunction face is mainly its end face, i.e., needs to undertake higher bearing capacity between its nut gasket component corresponding with end face, for solid
The nut gasket component for determining inner disc is easy to happen damage, is unfavorable for the smooth cold-drawn of steel pipe, and in addition support element is usually and one
Case is mounted on what the connecting rod on drawbench was threadedly coupled, since in Cold Drawing Process, meeting is touched in the connection of support element and connecting rod
There is prodigious pulling force, therefore prevented built on the sand using what is be threadedly coupled, in some instances it may even be possible to so that deformed threads cause support element to slip.
Utility model content
Purpose of the utility model is to solve the above problem, a kind of Tube Drawing anchorage is devised, including external disk, interior
Disk, it is characterised in that further include support element, connecting rod, positioning pin, the external disk upper edge external disk center line is equipped with through-hole, described interior
Disk is located in the through-hole of external disk, there is the space for cold drawing steel tube, the inner disc and support element between the external disk and inner disc
Connection, the support element include rod section, round platform portion, transition part, and the rod section, round platform portion and transition part are integrally formed, institute
Round platform portion is stated in inner disc, the round platform portion is connect by transition part with rod section, and the side of the transition part is curved surface,
Described rod section one end passes through the end face of inner disc to be docked with connecting rod, and the connecting rod is equipped with slot, pull rod one end peace
In slot, on the pull rod and it is equipped with location hole in connecting rod, the location hole is vertical with the axis direction of pull rod, institute
It states and fixed block is installed in connecting rod, reinforcing rib is installed between the fixed block and connecting rod, spiral shell is equipped in the fixed block
Hole, the screw hole are threadedly coupled with the top of positioning pin, and the lower part of the positioning pin assigns into location hole.
The connecting rod and the fixed seat of drawbench connect.
Baffle ring is installed, the baffle ring gear is in inner disc side in the rod section.
Advantageous effect：
1 the utility model round platform portion side undertakes bearing capacity when cold-drawn, since the side in round platform portion is in certain taper,
Larger power can be carried, compared with former technology, is avoided by nut come bearing capacity, and round platform portion passes through transition part and rod section
Connection, avoids the appearance of stress concentration；
It is connected and fixed by positioning pin between 2 the utility model connecting rods and rod section, passes through screw thread relative to original
Connection, can bear the pulling force of bigger, and fixed block is connect with rod section by reinforcing rib, and stability is further improved；
