Description
Technical field
The utility model relates to a kind of polishing machine for inner wall of steel pipe.
Background technology
Along with terminal client is more and more higher to steel pipe 8 surface quality requirements, as middle manufacturer steel pipe 8 produced and also need to improve constantly its surface quality.Under the demand of market conditions, current steel pipe 8 inwall glossing, completes by steel pipe 8 inner wall-burnishing machine mostly.Its primary structure of steel pipe 8 inner wall-burnishing machine of the prior art comprises some roller frames 1 be disposed adjacent, the round steel pipe 8 of strip is positioned between two adjacent roller frames 1, roller frame 1 rotates and drives the round steel pipe 8 of top to rotate (frictional force drive), the side of roller frame 1 is provided with the coaxial conduit 2 arranged with steel pipe 8, seesawed by driving mechanisms control conduit 2, conduit 2 is made to be arranged in steel pipe 8, conduit 2 opposite side is connected with drive motors, control conduit 2 to rotate backward with steel pipe 8, and then formation relative motion carries out polishing to steel pipe 8 inwall.
But in actual production process, the general length of round steel pipe 8 is all very long, and then makes conduit 2 also very elongated, in the process of front and back feeding and rotation, easily there is sideslip and arch upward up and down, the interior quality of finish of impact in conduit 2.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of polishing machine for inner wall of steel pipe, can play spacing effect better, prevents conduit in the process of front and back feeding and rotation, there is left and right sideslip and arch camber, and then quality of finish in improving.
For achieving the above object, the utility model provides following technical scheme: a kind of polishing machine for inner wall of steel pipe, comprise some roller frames, conduit and frame, described frame is connected with guide roller perpendicular to conduit setting direction, described guide roller outer surface is arranged with two pieces of catch, pressure roller is arranged with in parallel above described guide roller, described pressure roller and two pieces of catch surround the confined space that a described conduit of confession passes jointly, and described conduit is tangential on described confined space, be provided with pinch roller directly over adjacent two roller frames, each pinch roller and steel pipe are all tangent.
By adopting technique scheme, conduit passes and is arranged in round steel pipe again from confined space, guide roller and pressure roller play effect spacing up and down, prevent conduit from occurring arch camber, the catch be sheathed on outside guide roller plays the spacing effect in left and right, prevent conduit from the process of front and back feeding, occurring sideslip, conduit and confined space tangent, and then make conduit and catch, guide roller, the laminating of pressure roller outer surface is tightr, play position-limiting action better, and due to guide roller, conduit, rolling friction is between pressure roller, greatly can reduce the frictional force of conduit in feeding process, also pinch roller is provided with above steel pipe, steel pipe height can be made constant, and then prevent conduit from arching upward in the middle of the process of rotating.This technical scheme can play spacing effect better, prevents conduit in the process of front and back feeding and rotation, left and right sideslip and arch camber occur, and then quality of finish in improving.
The utility model is set to further: described frame is also provided with backing roll, and described backing roll is positioned at the lower surface of described conduit and arranges perpendicular to conduit.
By adopting technique scheme, because conduit is more elongated, the effect of support can be played, preventing conduit sagging.
The utility model is set to further: described guide roller is outside equipped with three groups of catch, often organizes catch and includes two pieces of catch.
By adopting technique scheme, interior polishing can be carried out to three round steel pipes simultaneously, raising the efficiency.
The utility model is set to further: all pinch rollers are interconnected by connecting plate, and is provided with its elevating mechanism moved up and down of control above described connecting plate.
By adopting technique scheme, the lifting of all pinch rollers can be controlled simultaneously, save time, enhance productivity.
This technical scheme compared with prior art has: can play spacing effect better, prevents conduit in the process of front and back feeding and rotation, left and right sideslip and arch camber occur, and then quality of finish in improving.

Detailed description of the invention
Referring to figs. 1 through Fig. 2, a kind of steel pipe 8 inner wall-burnishing machine of the utility model embodiment is described further.
A kind of steel pipe 8 inner wall-burnishing machine, comprise some roller frames 1, conduit 2 and frame 3, described frame 3 is connected with guide roller 4 perpendicular to conduit 2 setting direction, described guide roller 4 outer surface is arranged with two pieces of catch 5, pressure roller 6 is arranged with in parallel above described guide roller 4, described pressure roller 6 and two pieces of catch 5 surround the confined space that a described conduit 2 of confession passes jointly, and described conduit 2 is tangential on described confined space, be provided with pinch roller 7 directly over adjacent two roller frames 1, each pinch roller 7 is all tangent with steel pipe 8.
By adopting technique scheme, conduit 2 passes and is arranged in round steel pipe 8 again from confined space, guide roller 4 and pressure roller 6 play effect spacing up and down, prevent conduit 2 from occurring arch camber, the catch 5 be sheathed on outside guide roller 4 plays the spacing effect in left and right, prevent conduit 2 from the process of front and back feeding, occurring sideslip, conduit 2 is tangent with confined space, and then make conduit 2 and catch 5, guide roller 4, the laminating of pressure roller 6 outer surface is tightr, play position-limiting action better, and due to guide roller 4, pressure roller 6, rolling friction is between conduit 2, greatly can reduce the frictional force of conduit 2 in feeding process, also pinch roller 7 is provided with above steel pipe 8, steel pipe 8 can be made highly constant, and then prevent conduit 2 from arching upward in the middle of the process of rotating.This technical scheme can play spacing effect better, prevents conduit 2 in the process of front and back feeding and rotation, left and right sideslip and arch camber occur, and then quality of finish in improving.
Described frame 3 is also provided with backing roll 9, and described backing roll 9 is positioned at the lower surface of described conduit 2 and arranges perpendicular to conduit 2.
By adopting technique scheme, because conduit 2 is more elongated, the effect of support can be played, preventing conduit 2 sagging.
Described guide roller 4 is outside equipped with three groups of catch 5, often organizes catch 5 and includes two pieces of catch 5.
By adopting technique scheme, interior polishing can be carried out to three round steel pipes 8 simultaneously, raising the efficiency.
