Description
Technical field
The utility model relates to a kind of vertical conical wear resistant roll, particularly a kind of combined type vertical conical wear resistant roll being convenient for changing abrading section.
Background technology
Modern industry fast development makes the wearability of equipment to parts have higher requirement, as cement, mine, metallurgical, the grinding roller of the vertical grinder used in power station or various similar industry, mill and plate hammer for crusher etc., the hardness of conventional steel iron material and toughness normally contradiction, prior art many employings bimetallic compound and ceramet complex technique improve the wearability of material, the main wear-resisting position of this series products consumes completely, because wearability is lower, use value reduces at ductile metal position, but because itself and wear-resisting position are linked together by metallurgical binding and cannot realize dismantling, usually will as waste disposal, this will cause a large amount of wastings of resources.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of combined vertical taper wear resistant roll being convenient for changing abrading section fan-shaped wear-resistant block and the split of grinding roller body arranged, and can reach the effect of recycling grinding roller body.
To achieve these goals, the technical solution of the utility model is as follows: a kind of combined vertical taper wear resistant roll being convenient for changing wear-resistant block, comprise the grinding roller body of taper, it is characterized in that: the outer circumference surface of described grinding roller body is distributed with some axially extended grooves, the width of the notch of described groove is greater than the width of bottom land, the bore of described groove reduces from the osculum end of grinding roller body gradually to big opening end, and the both sides cell wall of described groove is provided with axially extended semicircle pin groove;
Fan-shaped wear-resistant block is installed in groove, all fan-shaped wear-resistant block composition conical rings, the middle part of the lower surface of described fan-shaped wear-resistant block is provided with the boss that cross section mates with the cross section of groove, described fan-shaped wear-resistant block is arranged in groove by this boss, semicircle pin groove on the corresponding groove cell wall in both sides of the lower boss of described fan-shaped wear-resistant block is provided with semicircle groove, when fan-shaped wear-resistant block is assemblied in groove, semicircle pin groove docking on semicircle groove on fan-shaped wear-resistant block and groove cell wall forms the through hole passed for pin, the pin coincide with this through hole is through this through hole, described fan-shaped wear-resistant block and pin are also spacing by the ring baffle being arranged on grinding roller body big opening end.
Preferred: the cross section of described groove is trapezoidal.
Wear-resisting for entirety roller shell is divided into the fan-shaped wear-resistant block of fritter by the utility model, only fan-shaped for fritter wear-resistant block need be put into groove, then insertion pin during installation just can realize being assembled into one with on grinding roller body, solve the problem of large-scale vertical taper grinding roller installation and removal difficulty.
When partial sector wear-resistant block damages, only can change the fan-shaped wear-resistant block of this partial destruction, can reuse for unspoiled fan-shaped wear-resistant block and grinding roller body, avoid the waste causing resource, reduce manufacturing cost.
It is spacing that fan-shaped wear-resistant block and grinding roller body pass through pin, avoids fan-shaped wear-resistant block upwards to exit.In addition because the structure of large-scale vertical taper grinding roller itself causes in use, fan-shaped wear-resistant block and pin easily move to big opening end, the osculum end of the bore of groove from grinding roller body reduces to big opening end by gradually, that is groove is cone tank, can avoid like this sliding to fan-shaped wear-resistant block to big opening end in use procedure.Play the effect of axial location.Meanwhile, we arrange ring baffle at the big opening end of grinding roller body, play the effect avoiding pin and fan-shaped wear-resistant block to slide to big opening end.
Finally we are by wear-resisting roller shell fritter, split casting, reduce the difficulty of the operations such as shaping, processing, heat treatment, improve yield rate.
In such scheme: described fan-shaped wear-resistant block is made up of antifriction metal (AFM) or metal alloy or ceramet high-abrasive material.
In such scheme: described fan-shaped wear-resistant block is made up of rich chromium cast iron or ni-hard cast iron or steel alloy, or described fan-shaped wear-resistant block has the ceramic-metal composites of ceramic oxide particle or carbide ceramic particles or compound ceramic particle to make by Near Surface Mounted.Fan-shaped wear-resistant block anti-wear performance obtained is thus good.
In such scheme: described grinding roller body is made up of cast iron or cast steel.
Preferred: described grinding roller body is made up of spheroidal graphite cast-iron or graphitic steel.These materials have obdurability simultaneously.
In such scheme, the surface that described grinding roller body contacts with fan-shaped wear-resistant block is coated with one deck viscoloid.The connection of the fan-shaped wear-resistant block of such increase and grinding roller body.
Beneficial effect: the utility model is by wear-resisting roller shell and grinding roller body split design, and wear-resisting roller shell is divided into some fan-shaped fritters, reduce difficulty of processing, improve yield rate, avoid the phenomenon causing because of the wearing and tearing of roller cover directly also being scrapped by grinding roller body simultaneously, reduce costs, the installation and removal of fan-shaped wear-resistant block and grinding roller body are convenient and simple.
