Description
Technical field
The present invention relates to the plant equipment for crop flying shear, more particularly to a kind of speed-differential drum flying shear blade locking system
System, belongs to steel rolling equipment field.
Background technology
Need to set a crop flying shear in hot steel strip continuous rolling unit, before finishing mill, shear head and the tail of made-up belt
Portion, bites beneficial to finishing mill to made-up belt, reduces impact of the made-up belt to roll, prevents occurring steel-fastening accident in the operation of rolling.Make
Coil of strip afterbody is concordant, it is easy to batches and ties up.
Rotary flying shears are a kind of conventional hot continuous rolling crop flying shears, and its is simple in construction, and weight of equipment is light, and rotary drum is around rotation
Central rotation, dynamic balance performance is good, can improve the shear rate of made-up belt, meets the use requirement of finishing mill.Fly in drum-type
Two pairs of cutting edges can be filled on the rotary drum cut, cutting head cutting tail are carried out respectively, using reliable.But upper and lower cutting edge can not vertically cut made-up belt,
Shear history blade clearance is change, and shearing is not substantially to completely cut through but squeeze and cut and deposit, and shearing quality is not high, is adapted to
For thinner thickness made-up belt, but thickness can be cut at present by technological transformation can reach 50mm made-up belt.Hot strip continuous-rolling machine
Conventional crop flying shear drum-type has two kinds of same peripheral speed, different peripheral speed.Different peripheral speed is the revolution of rotary drum cutting edge above and below differential speed type flying shear
Radius is different, is rotated with identical angular speed, and the linear velocity of cutting edge is different.This structure makes shearing force smaller, made-up belt cut-out
Effect more preferably, is applied widely on hot continuous rolling production line at present.
, it is necessary to more renew cutting edge after being worn and torn using a period of time cutting edge, cutting edge under changing again can be again after reconditioning
It is secondary to use, therefore need that a set of reliable cutting edge retaining mechanism is installed on rotary drum, cutting edge and rotary drum during flying shear work should be ensured
Connection is reliable, ensures that cutting edge can be separated quickly with rotary drum when changing cutting edge, more renew cutting edge again.
Former locking wedge block is connected by top locking nut with butterfly spring pull bar, and cutting edge retaining mechanism is when changing cutting edge
Easily voussoir occur can not open, and changing cutter is difficult；Former cutting edge locking cylinder is connected by point half clamp with rotary drum, cutting edge locking
When cylinder changes spare part, the phenomenon such as cutting edge locking cylinder dismounting difficulty.Former locking cylinder piston is split-type structural with butterfly spring pull bar.
Cutting edge fastening system of the present utility model using bolt holding type by locking cylinder be arranged on rotary drum on, locking wedge block with
Butterfly spring pull bar is connected using T-slot, and locking cylinder piston uses monoblock type with butterfly spring pull bar, and new construction locking cylinder is easy to
Change, cutting edge locking effect is good, and locking cylinder ejecting force is bigger, and changing cutter smoothly facilitates, save the advantage of replacing construction.

Be connected as a single entity composition frame structure；Upper rotary drum is respectively supported in frame with lower rotary drum with a pair of bearings, and left end installs a pair of operations
Side meshing gear, right-hand member installs a pair of transmission side meshing gears；Main motor drives lower rotary drum by reductor, and lower rotary drum is by passing
The dynamic upper rotary drum of side meshing gear driving, and fore side meshing gear reversely engages to eliminate gear clearance, makes rotary drum forward and reverse flat
It is steady to rotate；Respectively equipped with a pair of circumferentially 180 ° of cutting edges for being arranged symmetrically on upper rotary drum, lower rotary drum；Upper rotary drum cutting edge cutting edge is arc
Shape, for crop；Lower rotary drum cutting edge is a pair of staight scissors swords, for back-end crop；It is characterized in that described backing plate II, cutting edge, voussoir,
Backing plate I leans on wedge clamping, and cutting edge is fixed on rotary drum；The free voussoir that each wedge is arranged on 6 width is constituted, each wedge
Block is connected with the T connector of a locking cylinder by T-slot and realizes quick-replaceable cutting edge；Locking cylinder is fixed on rotary drum by screw；
Locking cylinder cylinder is built with the disk spring group of compression, the voussoir clamping cutting edge that the tension of clamping piston pull bar is connected with T connector；Change
During cutting edge, movable hydraulic station respectively by upper rotary drum, lower rotary drum fore side shaft end oilhole through hydraulic cylinder oil supplying hole to locking cylinder
Hydraulic oil is filled with, pitch brace is compressed disk spring group and is displaced outwardly, T connector ejection voussoir is promoted, loosens cutting edge, with special
Cutting edge is hung away with suspender, new cutting edge is installed, after movable hydraulic station pressure release, the disk spring group clamping piston pull bar of compression
Hold the voussoir being connected with T connector, the new cutting edge of wedging.
Compared with prior art, it is an advantage of the invention that it will be apparent that being mainly manifested in：
1st, cutting edge was connected reliably with rotary drum when speed-differential drum flying shear blade fastening system both can guarantee that flying shear work, and energy
Ensure that cutting edge can be separated quickly with rotary drum when changing cutting edge.
2nd, locking cylinder is arranged on rotary drum using bolt holding type, locking wedge block uses T-slot with butterfly spring pull bar
Connection, locking cylinder uses monoblock type with butterfly spring pull bar, it is easy to change, cutting edge locking effect is good, locking cylinder ejecting force is bigger,
