Description
Technical field
This utility model relates to seamless steel pipe technical field, especially a kind of auto parts machinery finish rolling seamless steel pipe.
Background technology
Auto parts machinery is to constitute the overall each unit of automobile and serve the product of automobile, automobile brand gets more and more now, car category also gets more and more, generally automobile can be divided into heavy-duty car, minicar, passenger vehicle three major types, raising along with people's living standard, the consumption of automobile is also got more and more by people, and this market of auto parts machinery becomes increasing, and auto parts machinery manufactured factory also in development at full speed in recent years.
Vehicle vent gas discharging pipe typically uses seamless steel pipe at present, long-time use along with automobile, dirt can be gradually adhered on the inwall of exhaustor, affect the output of electromotor, time serious, dirt can cause the blocking of exhaustor, the electromotor causing automobile cannot normally work, existing exhaustor is typically difficult to clean up when blocking, the mode cleaning mode one usually used is for soaking a period of time in exhaustor is placed on alkali liquor, another way is the exhaustor directly more renewed, and the cost used of both modes is the highest.
Utility model content
The technical problems to be solved in the utility model is: in order to solve in prior art the problem that the dirt in the seamless steel pipe used by motor vehicle exhaust emission is difficult to clean up, and existing provides a kind of auto parts machinery finish rolling seamless steel pipe.
This utility model solves its technical problem and be the technical scheme is that a kind of auto parts machinery finish rolling seamless steel pipe, including steel pipe body, there is on described steel pipe body the ladder hole that middle thin two ends are thick, the axis of described ladder hole linearly type, the annular inner core matched with it it is provided with in the thin segment of described ladder hole, gap is offered along its axis direction on the sidewall of described annular inner core, an interior ancient piece of jade, round, flat and with a hole in its centre for described annular inner core is provided with the strip block piece for covering described gap, the thin segment of described ladder hole forms step surface with the junction of thick section, it is equipped with annulus in the thick section of described ladder hole, described annulus is fixed on described step surface, the internal diameter of described annulus is equal with the internal diameter of described annular inner core.
When there is dirt in the annular inner core in this programme, annular inner core can be extracted out from steel pipe body, then annular inner core is broken into two with one's hands along its gap, therefore, can be the most easily by clean for the dirt removal on annular inner core, being installed on steel pipe body, block piece is possible to prevent dirt to be attached to steel pipe body again
Ladder hole inwall on, the annulus at ladder hole two ends can effectively prevent dirt enter annular inner core and steel pipe body between gap in.
Further, the two ends of described block piece are provided with pressing plate, and described pressing plate is provided with screw, and described screw is threadeded through described pressing plate with described steel pipe body.
In order to improve the service life of steel pipe, further, the outside of described steel pipe body is provided with antirust coat.
Further, described annulus is fixed by screws on described step surface.
Further, the material of described annular inner core is rustless steel.
The beneficial effects of the utility model are: auto parts machinery finish rolling seamless steel pipe of the present utility model, when there is dirt in its annular inner core, remove annulus and pressing plate, then annular inner core is extracted out from steel pipe body, then annular inner core is broken into two with one's hands along its gap, therefore, can realize the most easily by clean for the dirt removal on annular inner core, then be installed on steel pipe body.
