Description
Technical field
The utility model relates to rolling the rolling tightly, reel or the secondary process field of uncoiling of sheet metal strip, is specially a kind of coil car coil collapse prevention device.
Background technology
In the cold rolled strip steel production process, from annular furnace thin steel roll out because through high-temperature heat treatment, cause coil of strip more slack, after being turned into horizontal roll by vertical volume, the coil of strip gross distortion, if skip car does not have auxiliary coil collapse prevention device, coil of strip even can't place on the saddle of coil of strip car, reel of uncoiler more can't insert the function that the steel coil heart is finished uncoiling.Coil collapse prevention device adopts the single hydraulic cylinder rod chamber to shrink to reach the purpose of holding coil of strip tightly on the present coil of strip car, and enclasping force is not enough and cause slack coil of strip can't reach the state of proper circle; In addition, when arm was held tightly the major diameter coil of strip, secter pat was positioned at coil of strip center line below, and slack coil of strip can't be held into tightly the proper circle state, caused the scrolling difficulty of making comparisons, and had increased the production operation difficulty, had reduced production efficiency.
The utility model content
In order to overcome the defective of prior art, a kind of simple in structure, easy to use, strong rolling mill auxiliary equipment of the tight power of newspaper is provided, the utility model discloses a kind of coil car coil collapse prevention device.
The utility model reaches goal of the invention by following technical solution:
A kind of coil car coil collapse prevention device, comprise base and hydraulic cylinder, the cylinder body of hydraulic cylinder is fixed on the base, it is characterized in that: also comprise connecting rod, arm, synchronous gear, briquetting, hold piece and liner tightly, hydraulic cylinder, connecting rod, arm, synchronous gear and briquetting all respectively have two, two hydraulic cylinders are fixed on the base in the relative and symmetrical mode in the bottom of cylinder body, the top of two hydraulic cylinder piston rods connects respectively an end of two connecting rods by bearing pin, the other end of two connecting rods is welded on the middle part of two arms, one end of two arms and two synchronous gears are fixed on the base by bearing pin respectively, the gearteeth of two synchronous gears, briquetting is " C " font, the middle part of two briquettings is separately fixed at the other end of two rocking arms, briquetting can freely rotate, and an end of each briquetting respectively connects one by bearing pin and holds piece tightly, and the outside of holding piece tightly is the arc surface of indent, liner is separately fixed at the inboard of rocking arm and the inboard of holding piece tightly, and the outside of liner is the arc surface of indent.
Described coil car coil collapse prevention device is characterized in that: synchronous gear is fan-shaped, and the central angle of synchronous gear is at 15 °～45 °.
Described coil car coil collapse prevention device is characterized in that: comprise that also displacement transducer, displacement transducer are arranged on the piston rod of one of them hydraulic cylinder, displacement transducer is used for the stroke of control hydraulic cylinder.
When the utility model uses, the utility model is installed on the coil of strip car, shrink first the piston rod of hydraulic cylinder, make two rocking arms be flared to laterally extreme position, subsequently coil of strip is put into the coil of strip car, make the piston rod of hydraulic cylinder outwards promote connecting rod, and promote to the inside rocking arm through connecting rod; rocking arm passes through briquetting successively; hold piece and liner transmission of pressure tightly to compress coil of strip; it is free to rotate to hold piece tightly; the outer surface of the coil of strip of therefore can better fitting, two synchronisms that rocking arm rotates when synchronous gear guarantees hydraulic cylinder extension, liner can assist coil of strip after holding tightly near the proper circle state.As be provided with displacement transducer, then can according to the stroke of the signal controlling hydraulic cylinder of displacement transducer, can guarantee better to hold tightly precision and security.
The beneficial effects of the utility model are: simple in structure, easy to use, flexible for installation, and other equipment report tight power strong without interference, hold rear coil of strip tightly near the proper circle state, safe and reliable.
