Description

The correcting device that a kind of small-caliber steel pipe external diameter is less than normal
Technical field
The utility model relates to cold drawing steel tube production technical field, the correcting device that specifically a kind of small-caliber steel pipe external diameter is less than normal.
Background technology
In small-caliber steel pipe production process, because technological design is improper or production link control is improper, be everlasting and find the phenomenon of outer diameter of steel pipes (general little several or tens) less than normal in product inspection, sometimes still large batch of, steel pipe is caused directly to scrap, product can not delivery just-in-time, causes great economic loss and irremediable impact to company.
Utility model content
The purpose of this utility model is the correcting device providing a kind of small-caliber steel pipe external diameter less than normal, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
The correcting device that small-caliber steel pipe external diameter is less than normal, comprises for compressing and the V-shaped groove roller-way of supporting steel pipe and V-shaped groove pressing plate; For expanding the expander die of pipe diameter; Described V-shaped groove pressing plate is positioned at above V-shaped groove roller-way, is provided with pull bar in V-shaped groove pressing plate; Described pull bar left end is provided with locking nut; Being provided with the overhead gage for withstanding steel pipe and lower baffle plate on the right side of V-shaped groove pressing plate, offering circular hole between overhead gage and lower baffle plate, described Circularhole diameter is greater than pull bar diameter and is less than outer diameter of steel pipes.
As further program of the utility model: the length of described pull bar is greater than the length of steel pipe.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple to operate, easy to use, consume seldom, diameter of steel tube can be expanded slightly, meet quality requirement.Can reduce rear portion solid solution, aligning operation, direct pickling, albefaction obtain finished product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-V shape grooved roller road, 2-locking nut, 3-small-caliber steel pipe, 4-expander die, 5-V shape groove pressing plate, 6-overhead gage, 7-pull bar, 8-lower baffle plate.
Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
Referring to Fig. 1, the correcting device that a kind of small-caliber steel pipe external diameter is less than normal, comprising for compressing and the V-shaped groove roller-way 1 of supporting steel pipe and V-shaped groove pressing plate 5; For expanding the expander die 4 of pipe diameter; Described V-shaped groove pressing plate 5 is positioned at above V-shaped groove roller-way 1, is provided with pull bar 7 in V-shaped groove pressing plate 5, and the length of pull bar 7 is greater than the length of steel pipe; Described pull bar 7 left end is provided with locking nut 2; Being provided with the overhead gage 6 for withstanding steel pipe and lower baffle plate 8 on the right side of V-shaped groove pressing plate 5, offering circular hole between overhead gage 6 and lower baffle plate 8, described Circularhole diameter is greater than pull bar diameter and is less than outer diameter of steel pipes.
Operation principle of the present utility model is:
In use, fix steel pipe with a set of compression supporting steel pipe device, withstand steel pipe with overhead gage 6 and lower baffle plate 8, then hold expander die 4 by steel tube inner hole with pull bar 7, carry out micro-expanding distortion.Simple to operate, easy to use, consume low, rear portion solid solution, aligning operation can be reduced.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, various change can also be made under the prerequisite not departing from this patent aim.
