Abstract
The utility model relates to a steel billet gripping shear, which is positioned between a heating furnace outlet and a first rolling mill to grip the steel billet. The structure of the utility model is that: the steel billet gripping shear consists of a shear body 1, an upper shear arm 2, a lower shear arm 3, connecting bars, a gas cylinder and a bracket; the length of the upper shear arm is equal to the length of the lower shear arm; one ends of the upper shear arm and the lower shear arm are respectively articulated with the shear body, the other end thereof is articulated with the connecting bars, the lengths of the upper and lower shear arms are equal to the lengths of the connecting bars articulated with the upper and lower shear arms; the other ends of two connecting bars are articulated together with a gas cylinder rod, the gas cylinder is fixed on the bracket. The lengths of the upper and lower shear arms are equal and are also equal to the length of the connecting bars that are articulated with the upper and lower shear arms, thus achieving simultaneous action of two shear arms and ensuring the coincidence of shear blades to grip the steel billet. The utility model is characterized by reasonable structure, convenient use, improving shearing accuracy and shearing quality, etc.
Description
Technical field: the utility model relates to that a kind of steel billet card is disconnected to be cut, and is placed between furnace outlet and first rolling mill card steel billet that breaks.
Background technology: along with the continuous development of continuous casting installation for casting, a lot of steel rolling factories adopt continuous casting billet, rolling various steel.Between the furnace outlet and first rolling mill, install all generally that a decometer is disconnected to be cut, its effect is, during next procedure generation problem that the steel billet card is disconnected, remaining steel billet melts down, and cuts uselessly thereby reduce, and improves lumber recovery.Because the steel billet sectional dimension is bigger, in order to block disconnected steel billet, make that card is disconnected cuts a bigger entrance angle, the disconnected arm of cutting of cutting of card is done very longly usually, like this, control in lower shear arm the time action difficult with regard to comparing.Disconnected the cutting of present card generally all adopted long connecting rod control, promptly make a galianconism vertical with cutting arm at the revolution position of upper shear arm, the another side of lower shear arm is also made a galianconism, with a long connecting rod diagonal angle galianconism is linked up then, cut the arm lengths sum for two about the length of long connecting rod is equivalent to, when upper shear arm moves, its galianconism also follows by action, the pulling long connecting rod drives the lower shear arm action, and the cutting edge on the lower shear arm is lumped together, and cuts off steel billet.The disadvantage of this structure is, when wearing and tearing take place at the bearing pin position of long connecting rod, because it is longer to cut arm, causes the action error of long connecting rod to amplify, and mismatch appears in last lower scissor blade, steel billet can not be cut off, and causes the accident.
The utility model content: the utility model purpose provides that a kind of steel billet card is disconnected to be cut, and improves shear precision and shearing quality, solves the problems referred to above that prior art exists.
Technical scheme by cut body, go up lower shear arm, connecting rod, cylinder, support form the steel billet card and break and cut, the equal in length of upper shear arm and lower shear arm, their end is with to cut body hinged, the other end and rod hinge connection, the pitman arm equal in length hinged with last lower shear arm, the other end of two connecting rods and cylinder rod are hinged jointly, and cylinder is fixed on the support.
Because the equal in length of last lower shear arm, the pitman arm length hinged with last lower shear arm also equate, realized two actions when cutting arm, guaranteeing that cutting edge overlaps breaks the steel billet card.
The utlity model has rational in infrastructure, easy to use, improve characteristics such as shear precision and shearing quality.
Description of drawings: accompanying drawing is the utility model example structure schematic diagram.
Cut body 1 among the figure, upper shear arm 2, lower shear arm 3, last connecting rod 4, lower link 5, guide rail 6, cylinder 7, cylinder rod 8, upper scissor blade 9, lower scissor blade 10, support 11.
The specific embodiment:, further specify the utility model by embodiment below in conjunction with accompanying drawing.The equal in length of upper shear arm 2 and lower shear arm 3, their end is with to cut body 1 hinged, the other end and connecting rod 4,5 are hinged, the pitman arm equal in length hinged with last lower shear arm, and the other end of two connecting rods and cylinder rod 8 are hinged jointly, cylinder is fixed on the support 11, upper scissor blade 9, lower scissor blade 10 are separately fixed on upper shear arm 2, the lower shear arm 3, for guaranteeing shearing quality, guide rail 6 and cylinder rod 8 couplings are set, cylinder rod and two rod hinge connections can slide along guide rail together.Because the physical dimension of last lower shear arm is the same substantially, cylinder is positioned at the outside of cutting body and with to cut body vertical.When normal steel rolling, cylinder cylinder bar promotes two connecting rods simultaneously, will go up lower shear arm and open, and steel billet passes from last lower scissor blade with in the middle of cutting body, and when the needs card broke steel billet, cylinder spurs connecting rod and drives went up lower shear arm while closure, and the steel billet card is disconnected.
