Description
Technical field
The present invention relates to steekle mill production line field, and in particular to a kind of steekle mill product line device.
Background technology
Steekle mill is a kind of Heavy Plate Production equipment for being configured with rolling mill both sides and batching heating furnace.The curling of configuration
Steel billet can be always held at the condition of high temperature by heating furnace, so as to roll out the steel plate kind of lower thickness or high intensity.Generally
Heavy and medium plate mill be to prevent temperature from reducing that the specification of thickness of thin can not be produced, shorter blank can only be taken to carry out Rolling Production.
Therefore, steekle mill can be very good the thin steel plate kind of rolling thickness, its steel plate length can more than more than 500 meters,
It is 10 times of common heavy and medium plate mill.
In order to the steel plate collecting under the steekle mill rolling state by overlength gets up, need the steel after rolling by flying shear
Plate, collects according to after cold bed length segmentation.General steel plate sectional is 50 meters or so of the length of motherboard.
At present common cut deal cold bed collection system, the time that steel plate is transferred to from rollgang to be needed on cold bed is
More than 12 seconds.Common cut deal takes piecemeal to roll, and rolling time collects the time for needing considerably beyond cold bed, also would not be sudden and violent
Expose cold bed and collect the problem for not catching up with rhythm.
At present steekle mill is derived from common heavy and medium plate mill, and cold bed collection system structure is the same on its rear portion.It is former
Carry out the steel plate of one piece of entirety after segmentation, front block of steel plate must be accelerated to pull open considerably long distance with back steel plate by roller-way, no
Then steel plate can knock into the back in transfer during cold bed, or collide the accidents such as upper cooling bed device, that is, do not catch up with rhythm.
In order to ensure in limited distance, steel plate originally together is pulled open into required distance, current steekle mill is only
Last mill speed can be reduced, 7m/s is rolled by normal curling, be reduced to below 1.5m/s.
The content of the invention
To overcome the deficiency, it is an object of the invention to provide a kind of steekle mill product line device, improves steckel rolling
Mill speed during machine rolling, reduces workshop building cost, it is to avoid production accident occurs.
The technical solution adopted for the present invention to solve the technical problems is：A kind of steekle mill product line device, including it is defeated
Roller-way, cart slideway, flat c-type dolly, the flat c-type dolly is sent to be provided with upper strata bracing frame, lower layer support frame and connection board, institute
State and undertaking roller-way is equipped with above the bracing frame of upper strata, the space to be preserved between upper strata bracing frame and lower layer support frame is conveyed to steel plate
Roller-way, the flat c-type dolly bottom both sides are equipped with a wheel, and wheel is assemblied in cart slideway, can move along cart slideway
It is dynamic, chain is equipped with the flat c-type dolly, chain connects into closed loop system with flat c-type dolly, and chain one end is assemblied in dolly
On drive sprocket, chain opposite side is transferred on dolly tensioner sprocket wheel, and so flat c-type dolly can be moved in cart slideway,
Pull by chain or so, and driven by dolly drive sprocket, the cart slideway is arranged below lifting frame.
Further, two ends are arranged with connecting lever under the lifting frame, connecting lever and connecting rod assembly connection, one end of connecting rod with
Lifting hydraulic cylinder assembly connection.
Further, it is equipped with undertaking roller-way reducing motor on the undertaking roller-way.
Further, the undertaking roller-way reducing motor is set to reducing motor with encoder, and drive control is realized accurately determining
Position.
Further, the dolly drive sprocket and chain wheel drive reducing motor assembly connection, the chain wheel drive is slowed down electric
Machine is set to reducing motor with encoder, and drive control is realized being accurately positioned.
The invention has the advantages that：Simple structure, mill speed when improve steekle mill rolling improves production
Efficiency, reduces workshop building cost, can be prevented effectively from the situation that two pieces of steel plate head rear-end collisions hit, it is to avoid production accident is carried
High finished product rate.

Its working method is：
From accompanying drawing 3 to 6, under steel plate is acted in flat c-type dolly in rapid lift frame, two steel plate skies are constructed
Between.Fig. 3 is the schematic diagram of low-end trim one, and lifting frame 8 and flat c-type dolly 2 accept roller-way 31 also low in low-end trim a period of time
In rollgang 1, steel plate 4 can be freely accessible to cold bed area；Fig. 4 is the schematic diagram of low-end trim two, and when steel plate 4 is moved to system is needed
Dynamic moment, lifting frame 8 and flat c-type dolly 2 rapidly hold up steel plate 4, and rollgang is kept in the flat inner space of c-type dolly 2
1, without any stop, follow-up steel plate 4 can not slow down into cold bed area as previous piece；Fig. 5 illustrates for high-end trim one
Previous block of steel plate 4 is braked on figure, lifting frame 8 and the flat side of c-type dolly 2, while steel plate 4 is moved on cold bed wheel disc 11 under a high position
Portion, latter block of steel goes successively to rollgang 1.The schematic diagram of Fig. 6 positions high-end trim two, lifting frame 8 and flat c-type dolly 2 will be quiet
Previous block of steel plate 4 after only is steadily discharged on the face of cold bed wheel disc 11, then is returned in low level.
Previous block of steel plate 4 is held up and departs from former for 31 seconds under pre- deceleration regime by the undertaking roller-way of same linear velocity rotating speed
The plane of rollgang 1, and flat c-type car interior space accommodates original rollgang 1 just, it is allowed to the follow-up Freely input of steel plate 4.
Braking moment is needed when steel plate 4 is moved to, lifting frame 8 and flat c-type dolly 2 rapidly hold up steel plate 4, flat c-type
Rollgang 1 is kept in the inner space of dolly 2, and without any stop, follow-up steel plate 4 can not slow down entrance as previous piece
