Abstract
The utility model discloses a steel pipe school circle mould, including relative last mould and the lower mould that sets up, go up mould and lower mould all including installing die body dull and stereotyped and isosceles trapezoid, the narrow limit and the dull and stereotyped body coupling of installation of die body, the broadside of die body inwards caves in and has convex die cavity, the die cavity matches to be had a plurality of independences and can paste the adjustment circular arc board on the die cavity inner wall, and the internal surface of die cavity outwards extends has convex mould to follow to the mould extends to both sides respectively along both ends has flat following, adjustment circular arc board both ends are provided with the turn -ups, the turn -ups is with flat along being connected through the bolt. The beneficial effects of the utility model are that: simple structure, the installation of being convenient for, and can select the suitably adjustment circular arc board of size of installation according to steel pipe diameter's size to reach the purpose of adjustment die cavity size, improved round precision and the efficiency in steel pipe school.
Description
Technical field
This utility model relates to a kind of steel pipe school circle mould.
Background technology
At present, iron tower of power transmission line or communications tower are generally adopted steel tube tower, and the steel pipe that steel tube tower adopts needs to be attached installing, owing to the connected mode adopted between steel pipe is dock, therefore that the required precision of steel pipe school circle is higher.Traditional steel pipe school circle mode is to adopt manual operations, it is placed on forcing press by steel pipe, the circularity of steel pipe is corrected by rule of thumb and range estimation, but this mode does not ensure the circularity of steel pipe, even plane often occurs through the steel pipe pipe shaft of forcing press extruding.
Summary of the invention
For solving above technical deficiency, this utility model provides a kind of simple in construction, it is possible to increase the precision of steel pipe school circle, it is adaptable to the steel pipe school circle mould of different size steel pipe.
This utility model is realized by following measures:
A kind of steel pipe school of the present utility model circle mould, including the upper die and lower die being oppositely arranged, described upper die and lower die all include the die body installing flat board and isosceles trapezoid, the narrow limit of described die body is connected with installing flat board one, the broadside of die body caves inward the die cavity of circular arc, described die cavity coupling has adjustment arc plate that is some independent and that can be attached on mould intracavity wall, the inner surface of die cavity extends outward the mould edge of circular arc, and mould is extended with flat edge to both sides respectively along two ends, described adjustment arc plate two ends are provided with flange, described flange is connected by bolt with flat edge.
Above-mentioned installation flat board is provided with some long gains.
The beneficial effects of the utility model are: simple in construction, utilize long gain that upper die and lower die can be installed on the forcing press seat of honour easily, make to be formed between upper die and lower die the die cavity suitable with steel pipe profile during matched moulds, namely can normal operation；And can selecting appropriately sized adjustment arc plate is installed according to the size of diameter of steel tube, thus reaching to adjust the purpose of die cavity size, improve precision and the efficiency of steel pipe school circle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation after upper mould mounting and adjusting arc plate.
Wherein: mould on 1,2 counterdies, 3 install flat board, 4 mould edges, 5 flat edges, 6 long gains, 7 die bodys, and 8 adjust arc plate, 9 flange.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is done further detailed description:
As shown in Figure 1, 2, a kind of steel pipe school of the present utility model circle mould, including the upper mould 1 being oppositely arranged and counterdie 2, upper mould 1 and counterdie 2 all include the die body 7 installing flat board 3 and isosceles trapezoid, install and are provided with some long gains 6 on flat board 3.Easily upper mould 1, counterdie 2 can be installed on the forcing press seat of honour by long gain 6.
The narrow limit of die body 7 is connected with installing flat board 3 one, and the broadside of die body 7 caves inward the die cavity of circular arc, and the inner surface of die cavity extends outward the mould of circular arc along 4, and mould is extended with flat edge 5 respectively along 4 two ends to both sides.Upper mould 1 is relative with counterdie about 2, and the upper die cavity that between mould 1 and counterdie 2, formation is suitable with steel pipe profile during matched moulds, thus the steel pipe being placed in die cavity carries out school circle.
Die cavity coupling has adjustment arc plate 8 that is some independent and that can be attached on mould intracavity wall, adjusts arc plate 8 two ends and is provided with flange 9, and flange 9 is connected by bolt with flat edge 5.Adjust arc plate 8 size different, but all concentric with mould intracavity wall, if the diameter of steel tube justified by school is less, it is possible to increase one or more adjustment arc plate 8 on mould intracavity wall, thus reducing the diameter of die cavity, adapt to corresponding steel pipe.
The above is only the preferred implementation of this patent; it should be pointed out that, for those skilled in the art, under the premise without departing from the art of this patent principle; can also making some improvement and replacement, these improve and replace the protection domain that also should be regarded as this patent.
Claims (2)
1. a steel pipe school circle mould, it is characterized in that: include the upper die and lower die being oppositely arranged, described upper die and lower die all include the die body installing flat board and isosceles trapezoid, the narrow limit of described die body is connected with installing flat board one, the broadside of die body caves inward the die cavity of circular arc, described die cavity coupling has adjustment arc plate that is some independent and that can be attached on mould intracavity wall, the inner surface of die cavity extends outward the mould edge of circular arc, and mould is extended with flat edge to both sides respectively along two ends, described adjustment arc plate two ends are provided with flange, described flange is connected by bolt with flat edge.
