Abstract
The utility model relates to a hot rolling batches the production field, especially relates to prevent flat book screw rod device, a serial communication port, including threaded sleeve, lead screw one, lead screw two and fagging, the threaded sleeve both ends are equipped with lead screw one and lead screw two respectively, and lead screw one all is equipped with the fagging with two tip of lead screw, the screw thread of lead screw one and lead screw two revolves to opposite, the fagging is the arc, and the camber is unanimous with the coil of strip internal diameter. The threaded sleeve is provided with a through hole which is convenient for prying operation. Compared with the prior art, the beneficial effects of the utility model are that: 1) simple structure, low cost, convenient to use, through the supporting role of lead screw device, can alleviate or avoid the coil of strip flat package to a certain extent. 2) The adjusting function of the threaded sleeve can be suitable for steel coils with various specifications. 3) The rejection rate can be effectively reduced, and the production cost is reduced.
Description
Technical field
The utility model relates to the hot rolling reeling production field, relates in particular to a kind of anti-flat curled hair lever apparatus.
Background technology
Flat volume defective after in hot rolling is produced, often occurring batching, the reasons such as its main cause is loosening owing to supplied materials volume layer, high temperature stacking, stacking extruding cause, to be judged to useless when flat volume is serious, bring negative effect to production cost, urgent need is taken measures, flat volume defective appears when avoiding batching, the rate of reducing the number of rejects and seconds.
Summary of the invention
The purpose of this utility model provides a kind of anti-flat curled hair lever apparatus, provides support in the coil of strip inner radius, prevents flat volume defective, and the rate of reducing the number of rejects and seconds reduces production costs.
For solving the problems of the technologies described above, the technical solution of the utility model is:
Anti-flat curled hair lever apparatus, comprise screw shell, screw mandrel one, screw mandrel two and fagging, the screw shell two ends are respectively equipped with screw mandrel one and screw mandrel two, screw mandrel one and screw mandrel two ends are equipped with fagging, the thread rotary orientation of described screw mandrel one and screw mandrel two is opposite, described fagging is arc, and curvature is consistent with the coil of strip internal diameter.
Described screw shell is provided with the through hole of convenient sled roller operation.
Compared with prior art, the beneficial effects of the utility model are: 1) simple in structure, with low cost, easy to use, by the supporting role of lead screw device, can to a certain degree alleviate or avoid the flat volume of coil of strip.2) by the regulating action of screw shell, can be fit to the coil of strip of plurality of specifications.3) rate of effectively reducing the number of rejects and seconds reduces production costs.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is the utility model application state schematic diagram.
Among the figure: 1-screw shell 2-screw mandrel one 3-screw mandrel two 4-fagging 5-coil of strip 6-through holes
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, Fig. 2, it is the anti-flat curled hair lever apparatus example structure schematic diagram of the utility model, comprise screw shell 1, screw mandrel 1, screw mandrel 23 and fagging 4, screw shell 1 two ends are respectively equipped with screw mandrel 1 and screw mandrel 23, screw mandrel 1 and screw mandrel 23 ends are equipped with fagging 4, the thread rotary orientation of described screw mandrel 1 and screw mandrel 23 is opposite, and described fagging 4 is arc, and curvature is consistent with coil of strip 5 internal diameters.Screw shell 1 is provided with the through hole 6 of convenient sled roller operation.
Take 1780 production lines as example, in order to guarantee the support strength of lead screw device, the diameter of screw mandrel 1 and screw mandrel 23 is 130mm, Q345A material, normalized treatment.Fagging 4 thickness are 3mm.Because the internal diameter of coil of strip 5 is 762mm, so the length of screw shell 1 selection 510mm, the adjustable range of this lead screw device is 550-900mm, meets the demands fully.
