Description
Technical field
The utility model relates to a kind of improved cold roll forming strip productions to fly saw guide wheel device.
Background technique
In the winged saw system of original 76 welded pipe units, every set system configuration flies 4 sets of guide wheel device of saw, and function is mainly
It ensures and flies saw safe transmission.When flying saw operation, the axletree and vehicle frame being oriented in wheel assembly are mutually generated mill by vibration influence
Damage causes interference fit to fail, and generates gap；Running gap is beated so that baffle and axle sleeve abrasion, cause axletree along axis
To play, the interference fit for being oriented to wheel and bearing is influenced, failure is easily led to.In guiding wheel assembly the guiding wheel that wears and
Bearing must carry out replacement processing restorer running precision；In operation replacement, guiding wheel assembly before transformation, wear-out part
(axletree, wheel, bearing) need to carry out destructive disassembly, and time-consuming for maintenance replacement, and four after replacement guiding wheel leads circle
The depth of parallelism of rail adjusts, and installation accuracy is hard to reach the technical requirements of wheel 4 flatnesses in bottom.Guiding wheel before flying saw transformation
Equipment operation bounce and driving bring product quality problem and security risk seriously constrain production direct motion, average every before being transformed
It the 4-5 month must fly saw guiding wheel to problem and carry out primary adjustment maintenance replacement.Maintenance cost expense: (1) replacement is single flies saw
It is oriented to wheel, compressor emergency shutdown is needed, arranges three maintenance workers, average 6 hours used times, average cost of labor 3*210/8*6=472.5
Member；(2) goods, materials and equipments spare part expense 1250*4=5000 yuan, 5472.5 yuan of subtotal；(3) annual charge 5472*3=16416 yuan.
Summary of the invention
The purpose of this utility model is to provide a kind of improved cold roll forming strip productions to fly saw guide wheel device, maintenance
The replacement wear-out part used time greatly reduces, and four guiding wheels replace three check mans by original 6 hours, and it is small to reach improved 2
When, improve working efficiency.
The purpose of this utility model is achieved in that a kind of improved cold roll forming strip production flies saw directive wheel dress
It sets, the wheel carrier including being equipped with axletree, wheel carrier top is installed with a upper cover plate by bolt, and the bottom end of wheel carrier is spacious
It opens, engagement sleeves are equipped with an axle sleeve on the axletree in wheel carrier, and fly saw directive wheel and is mounted on by bearing on the axle sleeve,
Axletree end outside wheel carrier side is installed with fixed interstage sleeve, and grease channel is arranged in half axletree, profit
The outlet of oil pathway is arranged in the middle part of axletree, and keyway is arranged on the other half axletree axial surface, and it is another to be located at wheel carrier
Be equipped with winged saw directive wheel fixed ring on axletree outside side, the nut of axletree end setting by washer and
Axletree is carried out axially position by the winged saw directive wheel fixed ring.
Using in the open mouth in wheel carrier lower end, installation easy to disassemble is conducive to intense adjustment wheel flatness.Province is changed when maintenance
When it is convenient, adjust round guide contact plane degree up and down after solving the problems, such as installation.Wheel carrier top movable upper end cover is set, it is convenient
Point inspection, which is opened, to be checked.It uses flying saw axletree one end with cover locking is fixed, the other end is tightened by bolts, and controls axial float；
Simultaneously by bolt lock release, is exited along axial one direction, be convenient for changing part wear-out part wheel, axle sleeve and bearing.Using list
The straight-through connection flat key in side, transmission is more reliable, and dismounting is more convenient.The maintenance replacement wear-out part used time greatly reduces, four guiding wheels
Three check mans are replaced by original 6 hours, reaches improved 2 hours, improves efficiency 66%.Increase axis on flying saw axletree
Set reduces strength character requirement, disposes as vulnerable part, improve the Acceptable life of bearing.Using the utility model
Structure, (1) maintenance cost expense: replacement is single to fly saw guiding wheel, and year, replacement number was by former 3 adjustment of maintenance down
It is 2 times/year, reduces the repair time 33%.(2) it saves expense and arranges three maintenance workers according to inspection standard, the average used time 2 is small
When, average cost of labor 3*210/8*2=157.5 yuan, goods, materials and equipments spare part expense 1000*4=4000 yuan, 4157.5 yuan of subtotal.(3) fly
It is total to saw directive wheel maintenance cost: 4157.5*2=8315 yuan.Utility model device has simple installation, structurally reasonable, maintenance
The advantages that quick, can be widely used for the winged saw operation operation of the cold bending processing industry strip of sheet metal strip, ensure winged saw
Directive wheel equipment operation stabilization and efficiently.
Detailed description of the invention
The utility model is described in further detail below in conjunction with attached drawing.
Fig. 1 is the schematic view of the front view of the utility model.
