The roll surface of the roller press, disclosed by the utility model, comprises the roll surface and pillar nails, wherein pillar holes are formed on the roll surface, and the pillar nails are fixed in the pillar holes; the pillar nails are in transition fit with the pillar holes; the fit tolerance of the pillar nails and the pillar holes is in the range of (minus 0.5mm to plus 0.5mm). The roll surface of the roller press has the advantages that the embedding fit between the roller nails and the roll surface is reliable, the structure is reliable, the safety and the reliability are high, the installation is convenient; and the pillar nails are convenient to replace, so that the roll surface can be used repeatedly, the maintenance cost is reduced and the service life is extended.
Description
Technical field
The utility model relates to a kind of roll surface of rolling device, particularly a kind of roll squeezer of the roll-in milling equipment that is used for industries such as building material cement, metallurgical mine, coal, chemical industry.
Background technology
Along with the development of grinding technology in recent years, roll squeezer (or claiming high-pressure roller mill) based on material bed grinding principle has been widely used in grinding fields such as clinker, cement slurry, slag, slag, iron ore, chemical industry, has obtained tangible Increasing Production and Energy Saving effect.
Usually the roll squeezer roll surface adopts the method build-up wear-resistant layer of welding.But when roll squeezer roller tribulation grind materials, as slag, iron ore, quartz mine etc., the wearing layer of roll surface built-up welding can not satisfy wear-resisting and impact requirement, and roll surface often adopts the method for tungsten carbide button's post nail, to guarantee the service life of roll surface.The brill tooth of using for reference oil bit requires and method for embedding, is applied on the roll-in column nail roll surface, and the post nail adopts the brill teeth material of oil bit, adopts interference fit with cooperating of roll surface, and staggered gathering is embedded in roller surfaces.The roll-in column nail roll surface that adopts these methods to produce can satisfy instructions for use in a short time, but because the post nail adopts interference fit when assembling, for post bind be fitted on the position and do not deviate from use, the frictional force of post nail outer surface must be greater than the air drag in the sealing frame, this needs the post nail to adopt big interference fit to match with matrix, this not only needs special-purpose assembler's utensil, and since post nail when assembling, adopt big interference fit made the post nail bear huge extruding force, also need bear huge pinch shock power in use, often short-term inner prop nail will fracture, so can not satisfy the requirement in service life the service life of the post nail roll surface of producing by this method.Simultaneously, when the nail of the post on the roll surface damages beginning is limited several, will soon damage a sheet of, whole roller shell is just scrapped in the extremely short time, the employing interference fit can not be changed the post nail that has damaged, have only the post nail of waiting for whole roll surface all to damage, and whole roller shell is scrapped, change roller shell again.The replacing method of roller shell is: shut down, remove feed system, take the roll squeezer frame apart, take out the roller system at roller shell place, remove bearing block, roller is transported to specialized factory's heating remove old roller shell, the new roller shell of hot charging is inlayed the post nail and is increased some protection again; And then the bearing block of removing above, roller system, frame, the reduction of feed system dress, and just can reuse after testing, not only cost height, and downtime is quite long, and influence is produced normally.
Application number is 201020146215.1, the applying date is on March 23rd, 2010, name is called a kind of Chinese utility model patent of novel post nail formula roll surface structure, with application number be 201010136778.7, the applying date is on March 23rd, 2010, and title is a kind of Chinese invention patent application of post nail formula roll surface structure and post nail replacing method of roll-in mill, all discloses a kind of post nail formula roll surface structure, by with post nail and plunger hole matched in clearance, utilize bonding agent to connect.When the post nail damages, though can be convenient to the replacing of post nail by said method, owing to the connected mode of its bonding agent that adopts, when bonding agent is heated when reaching 180-200 ° of C, bonding agent promptly loses viscosity, therefore rub and the temperature rising when the post nail is in for a long time, when environment temperature was higher in addition, the post nail just can reach 180-200 ° of C easily with the plunger hole junction, at this moment along with the rotation of roll surface, the post nail is easy to come off, and influence is produced normally, even causes catastrophic failure.
