Abstract

The invention provides an online roller lateral wall polishing device for hot rolling of forklift frame channel steel. The online roller lateral wall polishing device comprises two supporting arms (4) and two grinding wheel disks (5), wherein the grinding wheel disks (5) are fixed to the supporting arms (4) and symmetrically and vertically arranged on two sides of a roller (6); the two supporting arms (4) are installed on a guide on an inlet side of the roller (6). The online roller lateral wall polishing device for hot rolling of the forklift frame channel steel can shorten the time for stopping a machine and polishing the lateral wall of the roller during rolling of the forklift frame channel steel, reduce the defects of bonding steel, improve production efficiency and improve the surface quality of the frame channel steel.

Description

A kind of online arrangement for grinding of hot rolling forklift door frame Channel Bar Steel Roller side wall
Technical field
The invention belongs to steel rolling equipment technical field, and in particular to a kind of hot rolling forklift door frame Channel Bar Steel Roller side wall is repaiied online Mill apparatus.
Background technology
Forklift door frame channel-section steel is used for making forklift door frame, and roller is arranged in the middle of the inside groove of forklift door frame channel-section steel, with inside groove Sidewall contact, is to ensure that pallet fork is steadily lifted, it is necessary to assure interior rooved face is smoothed.In the course of hot rolling of forklift door frame channel-section steel, Under finisher, horizontal roller angle of sides is less, steel bonding phenomenon easily occurs, cause gantry channel-steel medial wall not in course of hot rolling Smooth, after installing guide wheel, door frame is in lifting process interim card, it is impossible to use.In course of hot rolling, after there is steel bonding, need to shut down to enter and roll The wall reconditioning of roll side is carried out below machine with polishing machine.
At present, steel mill rolling forklift door frame channel-section steel when more than using shutdown reconditioning roll by the way of, have a strong impact on rolling efficiency.
The content of the invention
It is an object of the invention to when overcoming rolling forklift door frame channel-section steel at present, the efficiency that shutdown reconditioning roll is caused is low Defect, there is provided a kind of online arrangement for grinding of hot rolling forklift door frame Channel Bar Steel Roller side wall, the device overcome to solve the operation of rolling In there is steel bonding after need shut down reconditioning roll, affect rhythm of production problem.
To achieve these goals, the present invention provides a kind of hot rolling forklift door frame Channel Bar Steel Roller side wall online arrangement for grinding, Described device includes:Two support arms 4 and two grinding wheels 5, it is characterised in that the grinding wheel 5 is fixed on support arm 4, The both sides of roll 6 are vertically arranged at symmetrically;Described two support arms 4 are arranged in 6 entrance side guide and guard of roll.
In above-mentioned technical proposal, described device still further comprises base-plate 3 and bearing gusset 7;The base-plate 3 Bolt hole 11 is provided with, for bearing 3 is fixed to milling train;The bearing gusset 7 is elongate configuration, is provided with two screw rods 8, Every screw rod 8 is provided with two fixing nuts 9 and two adjusting nuts 10;The fixing nut 9 is used for 7 He of hold-down support gusset Screw rod 8, the adjusting nut 10 are used for fixation fork car gantry channel-steel passage and base-plate 3, by adjusting adjusting nut 10, i.e., The adjusting nut 10 of 8 the same side of screw rod is unclamped simultaneously, is tightened the adjusting nut 10 of opposite side, is realized that forklift door frame channel-section steel passage exists Bearing horizontal direction is moved, so as to grinding wheel 5 described in lateral adjustments and 6 sidewall contact of roll.
In above-mentioned technical proposal, each grinding wheel 5 is 4-6mm with 6 side wall distance range of roll.
In above-mentioned technical proposal, the support arm 4 is arranged on the gusset 1 of 6 entrance side guide and guard of roll.
It is an advantage of the current invention that:The device of the present invention can be reduced when shutting down reconditioning roll side wall when gantry channel-steel is rolled Between, steel bonding defect is reduced, improve production efficiency improves gantry channel-steel surface quality.

Fig. 2 is the overlooking structure figure of the device of the present invention;
Fig. 3 is the side block diagram of the device of the present invention;
Fig. 4 is the sectional structure chart in Fig. 2 along line A-A.
Specific embodiment
The present invention is described in further details with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of online arrangement for grinding of hot rolling forklift door frame Channel Bar Steel Roller side wall, described device includes:Two Support arm 4 and two grinding wheels 5, are respectively symmetrically the both sides for being vertically arranged at roll 6;For reconditioning roll side wall;Wherein, it is described Grinding wheel 5 is fixed on support arm 4.
Preferably, each grinding wheel 5 is 4-6mm with 6 side wall distance range of roll.
As shown in figure 1, in order to guide forklift door frame channel-section steel smoothly to nip roll, being provided with fork truck in the entrance side of roll Gantry channel-steel passage, the passage include:Gusset 1 and base plate 2, the gusset 1 are groove-like structure, for holding forklift door frame groove Bottom web;The support arm 4 is arranged on gusset 1;The base plate 2 is slab construction, along forklift door frame channel-section steel passage Length direction extends, i.e., along the introducing side of forklift door frame channel-section steel;The base plate 2 is used for holding the lower limb end of forklift door frame groove;Institute The end face for stating gusset 1 and base plate 2 is downward-sloping, is easy to rolled piece to enter forklift door frame channel-section steel passage from transfer roller, smoothly enters Milling train.In other embodiments, forklift door frame channel-section steel passage is tower structure.
During use, first base-plate 3 and bearing gusset 7 are installed on rolling mill frame window, and pass through bolt hole 11 It is fixed.1 head of the gusset is contacted with 6 roll surface of roll, and the grinding wheel 5 is fixed on support arm 4, and the support arm 4 is installed On gusset 1,6 side wall both sides of roll are symmetricly set on.Can be allowed by the forklift door frame channel-section steel passage that gusset 1, base plate 2 are constituted and be rolled Part smoothly enters milling train, when steel bonding occurs in roll side side wall, adjusts adjusting nut 10, grinding wheel 5 and 6 side side wall of roll Contact, realizes coping roller, realizes that grinding wheel 5 is departed from 6 side wall of roll by adjusting adjustment nut 10 after reconditioning is complete, and reduction is rolled Roller surface is worn and torn.Reach and realize the wall reconditioning of roll side, improve hot rolling gantry channel-steel surface quality, while improving rolling effect Rate.
As known by the technical knowledge, the present invention can be by other essence without departing from its spirit or the embodiment party of essential feature Case is realizing.Therefore, embodiment disclosed above, for each side, is all merely illustrative, and is not only.Institute Have within the scope of the present invention or be included in the invention in the change being equal in the scope of the present invention.
