Abstract
The utility model discloses an online grinding device for coiling machine pinch rolls. The online grinding device comprises a base, a cylinder, at least two guide rods, a clamp and grinding material disposed on the clamp. The cylinder provided with a piston rod in is disposed on the base. The piston rod is hinged with the clamp. The base is further provided with a guide rod seat. The guide rods are inserted in the guide rod seat and fixedly connected with the clamp. Each guide rod is a phi 40 forged steel fine grinding piece. The clamp is provided with a safety pin. The online grinding device is provided with the cylinder, compressed air is used as a power source, the waterproof grinding materials are used use grinding pieces, feed force is provided by the cylinder, grinding is performed through auto-rotation of the pinch rolls, stability is increased by the guide rods, the grinding materials are adjustable in the clamp, and emergency can be dealt with by the safety pin. The online grinding device is high in grinding efficiency and higher in precision compared with manual grinding.
Description
Technical field
The utility model relates to and belongs to technical field of ferrous metallurgy, relates in particular to the online arrangement for grinding of coiler pinch-roll.
Technical background
Coiler pinch-roll is the main tension device in the strip coiling operation, is used for providing and controlling the tension force of coiling band steel process.Be specially and utilize certain thrust that tension force is provided, control tension force by controlling rotating speed.
Pinch roll working face condition of work is harsh, easily occurs wearing and tearing, peels off, the damage type such as bonding.Wearing and tearing refer under the nominal situation condition, owing to always existing trace to relatively move between pinch roll working face and belt steel surface, produce thus frictional force, make working face wearing and tearing, thus the damage type that causes the roller footpath to reduce.It is not inconsistent actual roller footpath and calibration rollers footpath, affects tension force and controls.
The main cause of peeling off is tired.The coiler pinch-roll working face with the band steel between for line contacts, operating temperature is more than 600 ℃, surface pressure is powerful, operating temperature is high.Along with pinch roll rotates, on its working face, each bus contacts, rolls the band steel repeatedly, causes simultaneously alternate stress and thermal stress.These two kinds of stress make and occur fatigue damage in working face, cause and peel off.Damage belt steel surface.
Bonding refers to the sticky object that occurs on the pinch roll working face, and it generally comes from belt steel surface, produces under the conditions such as suitable temperature, pressure and linear velocity, grows up.Damage belt steel surface.
The online life-span of coiler pinch-roll is determined by wear extent, generally take rolling tonnage as unit of account.The pinch roll to the life-span does not peel off, bonds as occurring, and replacing or artificial reconditioning are consuming time, disturb rhythm of production.
The utility model content
In view of this, the purpose of this utility model is to propose the online arrangement for grinding of a kind of coiler pinch-roll, and grinding efficiency is high, and the more artificial reconditioning of precision is better.
Technical solutions of the utility model realize with following method:
The online arrangement for grinding of a kind of coiler pinch-roll, wherein, by base, cylinder, guide post, fixture, the abrasive material that is arranged on fixture consists of, cylinder is arranged on base, be provided with piston rod in cylinder, piston rod and fixture are hinged, also are provided with the guiding pole socket on base, guide post interts in the guiding pole socket, and guide post is fixedly connected with fixture.
Guide post is at least two.
Guide post is φ 40 forged steel correct grinding parts.
Fixture is provided with safety pin.
The good effect of technical solutions of the utility model is:
Because the utility model is provided with cylinder, take compressed air as power source, being provided with anti-water abrasive material is the grinding part, provide centripetal force by cylinder, produce grinding motion by the pinch roll rotation, be provided with guide post to strengthen stability, abrasive material is adjustable in fixture, be provided with simultaneously safety pin and can tackle emergency case, this device grinding efficiency is high, and the more artificial reconditioning of precision is good.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
