Abstract
The utility model discloses a push-disc type air bag for a steel mill flying shear. The push-disc type air bag for the steel mill flying shear comprises an air bag body which is provided with an air mouth and is in a circular ring shape, in addition, the air bag body is formed by an outer rubber layer, a framework layer and an inner rubber layer in a composite mode, a cross section of the air bag body is in a flat shape, and two sides of an inner cavity of the air bag body are respectively provided with a circular arc end. The push-disc type air bag for the steel mill flying shear is arranged between a friction chassis of a friction clutch and a gear disc of the friction clutch and fixed through the adoption of bolts. After the push-disc type air bag for the steel mill flying shear is gas-filled, the air bag pushes the gear disc to be fully contacted with a gear disc at the other end, force of friction is generated, and a function of torque transmission is achieved. Inflation pressure of the air bag is larger, the friction force between the gear discs is larger, when the friction force is larger than or equal to force of radial rotation, the flying shear can move, steels are cut off, and working efficiency is high.
Description
Technical field:
The utility model relates to a kind of pressure-bearing air bag, particularly relates to a kind of steel mill flying shears pusher-tray type air bag.
Background technique:
The shear action of steel mill's flying shears is controlled by friction clutch, and this friction clutch is axially work, is comprised of the chassis that rubs, two fluted discs, connecting bolt and springs.When two fluted discs were subject to External Force Acting, both fully contact, produced larger frictional force, plays the transmission torsional interaction, and during more than or equal to the power of radial rotating, flying shear will move when frictional force, the cut-out steel, thus finish the work.Promote at present external force means complex structure and dismounting inconvenience that fluted disc moves, inefficiency and workman's labor intensity is large.
The model utility content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, steel mill's flying shears pusher-tray type air bag of a kind of simple in structure, easy to use, high working efficiency and long service life is provided.
The technical solution of the utility model is:
A kind of steel mill flying shears pusher-tray type air bag contains air sac, is provided with valve on described air sac, and described air sac is circular, and described air sac is composited by outer glue-line, framework layer and inner glue layer, and the cross section of described air sac is flat.
Described valve is four and is uniformly distributed along the circumference.
The inner chamber both sides of described air sac are respectively arranged with arc end.
The beneficial effects of the utility model are:
1, the utility model is arranged between the friction chassis and fluted disc of friction clutch, adopts bolt to fix, and after airbag aeration, air bag promotes fluted disc and fully contacts with the other end fluted disc, produces frictional force, plays the transmission torsional interaction.Air bag inflation pressure is larger, and the frictional force of fluted disc and fluted disc is just larger, and during more than or equal to the power of radial rotating, flying shear will move, and cuts off steel, thereby finishes the work when frictional force.
2, the utility model air sac adopts flat, has increased lifting surface area, has strengthened the impacting force of air bag, better impels two fluted discs fully to contact.
3, four valves of the utility model employing, and four valves are uniformly distributed along the circumference, and can realize fast aeration and venting, increase work efficiency.
4, simple in structure, easy to use, the high working efficiency of the utility model and long service life, be widely used in the fields such as cold shears, cold bed, press machine, building machinery, oil, boats and ships, harbour, forging and pressing, printing, weaving, welding, be easy to promotion and implementation, economic benefit is good.
Description of drawings:
Fig. 1 is the structural representation that steel mill's flying shears are used the pusher-tray type air bag;
Fig. 2 is the plan view that steel mill shown in Figure 1 flying shears are used the pusher-tray type air bag.
Embodiment:
Embodiment: referring to Fig. 1-Fig. 2, in figure, 1-valve, the outer glue-line of 2-, 3-framework layer, 4-inner glue layer, 5-air sac, 6-arc end.
Steel mill's flying shears contain air sac 5 with the pusher-tray type air bag, are provided with valve 1 on air sac 5, and wherein: air sac 5 is circular, and air sac 5 is composited by outer glue-line 2, framework layer 3 and inner glue layer 4, and the cross section of air sac 5 is flat.
Valve 1 is four and is uniformly distributed along the circumference, and valve 1 also can adopt one, two, three etc. certainly, determines according to need.The inner chamber both sides of air sac 5 are respectively arranged with arc end 6, make air sac 5 loads more even, and stress surface is larger.
During use, the utility model is arranged between the friction chassis and fluted disc of friction clutch, adopts bolt to fix, and after airbag aeration, air bag promotes fluted disc and fully contacts with the other end fluted disc, produces frictional force, plays the transmission torsional interaction.Air bag inflation pressure is larger, and the frictional force of fluted disc and fluted disc is just larger, and during more than or equal to the power of radial rotating, flying shear will move, and cuts off steel, thereby finishes the work when frictional force.
The above is only preferred embodiment of the present utility model, is not the utility model is done any pro forma restriction, and every any brief modification of doing according to the utility model all still belongs to protection domain of the present utility model.
Claims (3)
1. steel mill's flying shears pusher-tray type air bag, contain air sac, is provided with valve on described air sac, it is characterized in that: described air sac is circular, and described air sac is composited by outer glue-line, framework layer and inner glue layer, and the cross section of described air sac is flat.
