Description
Technical field
The utility model relates to steel tube fabrication technique field, relates to a kind of coolable ratio-frequency welded tube compression roller device in particular.
Background technology
Current most of HFW welded pipe factory, for roll rolipass design, particularly to compression roller, all generally directly spray roll outer surface to reach cooling roll and bearing with cooling water, the shortcoming of this form is: one, cooling water directly sprays in roller surface and easily causes cooling fluid to flow to the weld edge of heating, produce hydrogen crackle, cause weld defect.Two, cooling water act on roller surface can only breaker roll surface cool, heat is passed to Bearing inner and very easily damages bearing.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art, a kind of coolable ratio-frequency welded tube compression roller device is provided, this device improves by carrying out design to extrusion roll shaft, cooling water can be circulated and enter extrusion roll shaft inside, so both ensureing the service life of roll and bearing, again without the need to carrying out external refrigeration to compression roller, eliminating because directly spray roll outer surface easily causes cooling fluid to flow to the weld edge of heating, produce the drawback of hydrogen crackle, improve product quality.
The utility model is reach the technical scheme that above-mentioned order adopts to be:
A kind of coolable ratio-frequency welded tube compression roller device, comprise a pair upper compression roller arranged side by side and an offside compression roller, the upper extrusion roll shaft part hollow of described upper compression roller, the side extrusion roll shaft of described side compression roller is provided with a through hole, upper extrusion roll shaft axle mouth is provided with a snap joint, snap joint is provided with water inlet pipe mouth and outlet pipe, and water inlet pipe mouth connects water inlet pipe, and effluent pipe mouth connects one end of outlet pipe; Extrusion roll shaft mouth place, described side is provided with outlet pipe interface, connects the other end of described outlet pipe.
Described snap joint is provided with the rigid conduit being communicated with water inlet pipe mouth, rigid conduit stretches into the hollow space of extrusion roll shaft, when utility model works, cooling water enters this rigid conduit by water inlet pipe mouth, then the hollow space of extrusion roll shaft is entered, the effect of this pipeline prevents cooling water from refluxing, and makes the process of recirculated cooling water more unobstructed.
The cooling procedure during work of this utility model: cooling water enters in upper extrusion roll shaft by water inlet pipe, enters in outlet pipe through snap joint, the through hole through side extrusion roll shaft flows into backwater ditch, completes a circulation.
The beneficial effects of the utility model are: this device effectively raises welding quality and product lumber recovery after using, and extends the service life of roll and bearing, decreases the replacing of roll and bearing, reduce production cost.

Detailed description of the invention
Embodiment 1
Below in conjunction with drawings and Examples, the utility model is further illustrated.
A kind of coolable ratio-frequency welded tube compression roller device, comprises a pair upper compression roller 6-1,6-2 arranged side by side and offside compression roller 7-1, a 7-2;
Upper extrusion roll shaft 1-1,1-2 part hollow of described upper compression roller 6-1,6-2, is used for splendid attire cooling water during work; The side extrusion roll shaft 7-1 of described side compression roller 5-1,5-2,7-2 is provided with a through hole, and through hole is used for trickling cooling water; Upper extrusion roll shaft 1-1,1-2 axle mouth is provided with snap joint 3-1,3-2 snap joint 3-1, a 3-2 and is provided with water inlet pipe mouth 8 and effluent pipe mouth 9, water inlet pipe mouth 8 connects water inlet pipe 2-1,2-2, effluent pipe mouth 9 connects one end of outlet pipe 4-1,4-2, and the other end connects outlet pipe interface 10-1,10-2 of being positioned at extrusion roll shaft 7-1,7-2 mouth place, side.
Described snap joint 3-1,3-2 are provided with the rigid conduit 11 being communicated with water inlet pipe mouth 8, this rigid conduit 11 stretches into the hollow space of extrusion roll shaft when utility model works, cooling water enters this rigid conduit 11 by water inlet pipe mouth, then the hollow space of extrusion roll shaft 1-1,1-2 is entered, the effect of this pipeline prevents cooling water from refluxing, and makes the cyclic process of cooling water more unobstructed.
The cooling procedure during work of this embodiment: cooling water enters in upper extrusion roll shaft 1-1,1-2 by water inlet pipe 2-1,2-2, enter in outlet pipe 4-1,4-2 through snap joint 3-1,3-2, through hole through side extrusion roll shaft 7-1,7-2 flows into backwater ditch, completes a circulation.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
