Background technology
When the work of finishing units such as the pickling of the cold rolling unit and the roll coil of strip, annealing, shearing, coating, to finish usually the roll coil of strip transportation, material loading, rolling, batch, unload actions such as volume and weighing, constitute the serialization operation process.
In the process of rolled strip, this type of pull reel not only is used for spooling, also is used for finishing the work of uncoiling sometimes; And rely on this type of pull reel can set up the front and back tension force of band, can reduce draught pressure like this, improve the rolling stability of roll.But in the existing coiled up device, reel is unified to adopt the hydraulic pressure guide rod structure, because the hydraulic pressure guide rod is processed, the restriction of installation and usage condition, occurs the leakage of oil of jaw place easily and not tight situation is stung in the jaw material folding, causes inconvenience to activity in production.
Summary of the invention
In order to overcome the deficiency in the background technology, the invention provides a kind of flexible jaw swing arm non-expansion drum device, described flexible jaw swing arm non-expansion drum, when hydraulic cylinder piston moves, drive arc motion by connector, thereby realize adjustable clamp oralia and fixation clamps oralia open and, promptly jaw clamps and unclamps, realization work purpose; The present invention has overcome the problem of jaw leakage of oil and jaw material folding, has satisfied production technology greatly, and is easy to use.
For achieving the above object, the present invention adopts following technical scheme:
A kind of flexible jaw swing arm non-expansion drum device comprises jaw engine installation, jaw registration device, jaw engine installation bearing, jaw registration device bearing; Described jaw engine installation passes hydraulic actuating cylinder otic placode hole by bearing pin c and is hinged on the jaw engine installation bearing and forms, and described jaw engine installation bearing is made up of in reel one side bolt d and pin fixed bearing; Described jaw registration device is set to arc, and top, arc upper end is provided with the fixing adjustable clamp oralia by bolt b; The fixation clamps oralia is fixed on reel upper end by bolt c and in adjustable clamp oralia corresponding position; Bottom, described arc lower end is hinged on the jaw registration device bearing by bearing pin a, and jaw registration device bearing is fixedly installed on the reel opposite side by bolt a with baffle plate; The hydraulic cylinder piston rod end of jaw engine installation is connected by connector with arc upper end of jaw registration device; When hydraulic actuating cylinder is withdrawn, drive arc lower end and be rotated down around jaw registration device bearing, the fixing adjustable clamp oralia in arc upper end is separated with the fixation clamps oralia; When hydraulic actuating cylinder stretches out, drive arc lower end and rotate up around jaw registration device bearing, make arc upper end fixing adjustable clamp oralia and regular jaw plate closing.
Described flexible jaw swing arm non-expansion drum device, the hydraulic cylinder piston rod end is connected by nut with connector.
Described flexible jaw swing arm non-expansion drum device, arc upper end is hinged by bearing pin b and connector.
Because the beneficial effect that has adopted technique scheme, the present invention to have is:
1, can regulate the cylinder pressure size and change the jaw gripping power according to the actual production demand, the adjustment mode is flexible.
2, since hydraulic cylinder piston when motion drive arc motion by connector, thereby realize adjustable clamp oralia and fixation clamps oralia open and, promptly jaw clamps and unclamps, and has solved the leakage of oil problem at reel jaw place fully.
3, the present invention is simple in structure, makes, installation requirement is low; And operation is simple, is easy to control and maintenance.
