A kind of wire rod rolling roller mill inlet guide structure
Technical field
The invention belongs to steel rolling mill's high-speed rod manufacture field, be specifically related to a kind of wire rod rolling roller mill inlet guide structure.
Background technology
On steel rolling mill's high-speed wire production line h roughing mill, rolled piece is entering in pass before rolling and need be clamped and could be entered in pass smoothly by guide and guards, what usually adopt on three-high mill in current industry is guide plate clamping, on stainless steel high-speed wire production line, because requiring far away higher than the requirement of common iron product quality, rolled piece is before entering pass, it is travelling state, clamping with guide plate the problem brought is scratching, because it is sliding friction, end product quality is impacted, effectively scratching can be avoided as increased guide plate gap, but the phenomenon of rolled piece instability can be caused.
Summary of the invention
The object of the invention is to provide a kind of wire rod rolling roller mill inlet guide structure for solving the problems of the technologies described above.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs:
A kind of wire rod rolling roller mill inlet guide structure, comprise the box body with wire guide passage, described box body comprises the box sidewall being positioned at both sides, the deflector roll for wire rod scratching being positioned at the box diapire at the bottom of box and being symmetricly set on two box sidewalls, and described box body front end is provided with the side guide plate for coordinating with roller mill.
As preferably, described box sidewall is vertically provided with eccentric shaft, and described deflector roll is located on described eccentric shaft by bearing holder (housing, cover).
As preferably, described eccentric shaft comprise the adjustment rotating shaft at top and be connected to regulate bottom rotating shaft and and regulate the deflector roll socked shaft of eccentric setting between rotating shaft, described regulating rotary shaft diameter is greater than described deflector roll socked shaft diameter, described deflector roll is sheathed on described deflector roll socked shaft, described deflector roll socked shaft lower end is arranged with and regulates the concentric eccentric bushing arranged of rotating shaft, and described eccentric bushing is arranged on described box body rotationally.
As preferably, described adjustment rotating shaft top is removably fixed with for driving the connecting plate regulating axis of rotation by screw one, and described connecting plate is removably fixed on described box body by screw two.
As preferably, described connecting plate is ring flange.
As preferably, described deflector roll socked shaft is connected by flat key and described eccentric bushing.
As preferably, described deflector roll is located on described deflector roll socked shaft by bearing holder (housing, cover).
As preferably, the upper and lower two ends of described deflector roll are provided with for bearings mounted installation portion.
As preferably, described bearing outer end is provided with sealing thrust lid.
As preferably, described two box sidewalls are respectively provided with 1-2 deflector roll, described ring flange are provided with the polygon turning cylinder being convenient to rotate ring flange, in the middle part of described polygon turning cylinder, be provided with lubricating cup and the oil pocket for sending oil for eccentric shaft.
In sum, the present invention has following beneficial effect:
1, the application is by being provided with deflector roll at box sidewall thus the friction between wire rod and box sidewall being become rolling friction, thus the scratch avoided between wire rod and box sidewall, use the setting of eccentric shaft to make the deflector roll spacing on two box sidewalls adjustable simultaneously, can mate with rolled piece according to the spacing of the size adjusting rolling deflector roll of actual rolled piece, the clamping effect of guide and guard when ensureing to roll different rolled piece, and then ensureing the quality of finished product, guide and guard can be used for the rolling of multiple size rolled piece.
2, the application's structure is simple, and easy to process, cost is low, and guide and guard are without the need to changing, and deflector roll adjustment flexibly.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
This specific embodiment is only explanation of the invention; it is not limitation of the present invention; those skilled in the art are after reading this description; the amendment not having creative contribution can be made as required, as long as but be all subject to the protection of Patent Law in right of the present invention to the present embodiment.
Embodiment one:
A kind of wire rod rolling roller mill inlet guide structure, comprise the box body 1 with wire guide passage, described box body comprise be positioned at both sides box sidewall 8, be positioned at the box diapire 3 at the bottom of box and be symmetricly set in two on the two box sidewalls deflector rolls 2 for wire rod scratching, described box body front end is provided with the side guide plate 4 for coordinating with roller mill.
Side guide plate is point arc-shaped guide plate out.For being connected better with roller mill.
Described box sidewall is vertically provided with eccentric shaft 5, and described deflector roll is located on described eccentric shaft by bearing holder (housing, cover).
Described eccentric shaft comprise the adjustment rotating shaft 51 at top and be connected to regulate bottom rotating shaft and and regulate the deflector roll socked shaft 52 of eccentric setting between rotating shaft, described regulating rotary shaft diameter is greater than described deflector roll socked shaft diameter, described deflector roll is sheathed on described deflector roll socked shaft, described deflector roll socked shaft lower end is arranged with and regulates the concentric eccentric bushing 53 arranged of rotating shaft, and described eccentric bushing is arranged on described box body rotationally.
Due to eccentric setting between deflector roll socked shaft and adjustment rotating shaft, thus by rotating the change regulating rotating shaft to drive the relative box body position of deflector roll socked shaft, and then the spacing between the deflector roll of change on two box sidewalls, to be applicable to the processing of different size wire rod.Eccentric bushing is concentric with adjustment rotating shaft, ensures the smooth and easy of the firm of deflector roll socked shaft and rotation.
Described adjustment rotating shaft top is removably fixed with for driving the connecting plate regulating axis of rotation by screw 1, and described connecting plate is removably fixed on described box body by screw 2 64.Described connecting plate is ring flange 6.
During use, screw two and box body are unclamped, thus rotatable ring flange, and then drive adjustment axis of rotation by ring flange, and regulate axis of rotation from peripheral operation, easy to adjust.
Described deflector roll socked shaft is connected by flat key 54 and described eccentric bushing.Described deflector roll is located on described deflector roll socked shaft by bearing holder (housing, cover).The upper and lower two ends of described deflector roll are provided with for bearings mounted installation portion.Described bearing outer end is provided with sealing thrust lid 7.
Embodiment two:
Be in different from above-described embodiment is respectively provided with 1 deflector roll on described two box sidewalls, described ring flange is provided with the polygon turning cylinder 61 being convenient to rotate ring flange, in the middle part of institute judge polygon turning cylinder, is provided with lubricating cup 62 and oil pocket for sending oil for eccentric shaft.Polygon turning cylinder is square turning cylinder.
The application is by being provided with deflector roll at box sidewall thus the friction between wire rod and box sidewall being become rolling friction, thus the scratch avoided between wire rod and box sidewall, use the setting of eccentric shaft to make the deflector roll spacing on two box sidewalls adjustable simultaneously, can mate with rolled piece according to the spacing of the size adjusting rolling deflector roll of actual rolled piece, the clamping effect of guide and guard when ensureing to roll different rolled piece, and then ensureing the quality of finished product, guide and guard can be used for the rolling of multiple size rolled piece.
