Abstract
The invention belongs to the field of metallurgical machinery, which consists of a mandrel 1, a roller sleeve 2, a positioning wedge 4 and a positioning sleeve 3, and is characterized in that: the roller sleeve 2 is arranged on the mandrel 1 after being heated and expanded, and is firmly combined with the mandrel 1 after being cooled; the positioning wedge 4 is placed in the groove 5 of the mandrel 1; the positioning sleeve 3 is arranged on the positioning step 7 of the mandrel 1 after being heated and expanded, and a part of the positioning sleeve 3 clamps the positioning wedge 4; the roller has no key groove and thread, is simple to process and can bear larger alternating stress; the outer diameter of the roller sleeve 2 can reach 300-600 mm, the service life can be prolonged by more than 2 times, and the cost is reduced by 30%.
Description
The invention belongs to field of metallurgical machine, be applicable to the roll of steel, copper material, aluminium rolling machinery.
The rolling common use solid roll of metal material.Its shortcoming is:
1. the waste of material is big.Roll uses through repeatedly repairing, and diameter is reduced to has in the end when scrapping most, and the material of being discarded is greater than 60% of whole roll.
2. the roll material therefor is difficult for selecting.Adopt high alloy material, the roll cost is too high; Adopt low alloy material, roll is too short again service life.Adopt bimetal composite casting, because the roll sectional dimension is bigger, cause heat treated cooling velocity too slow, thereby the case depth on roll top layer is not enough, the performance of high alloy material can not get fully playing.
The rolling existing assembly roller of metal material is to be formed by mandrel, roller shell, driving key, nut combinations.Its shortcoming is:
1. mandrel and roller shell are combination mutually, respectively have a keyway.Keyway not only makes the local thickness of roller shell reduce, and the sharp corner of keyway easily produces stress and concentrate, and makes roller shell be easy to generate crackle.Therefore roller shell can not bear the big alternate stress in the operation of rolling, the diameter of roller shell and all be restricted with the selection of material.
2. the nut loading and unloading difficulty that size is big.
3. the processing of keyway and nut is complicated.
The objective of the invention is to design a kind of assembly roller simple, easy to loading and unloading, that use reliably, can bear big alternate stress of processing.
Reaching of above-mentioned purpose of the present invention, the technical scheme of employing is: roll is made of mandrel 1, roller shell 2, locating wedge 4, positioning sleeve 3, and an end of mandrel 1 has a positioning step 6, and the other end has a positioning step 7 and ring-like detent 5; Roller shell 2 is contained on the mandrel 1 after adding thermal expansion, and firmly make up with mandrel 1 the cooling back, relies on the frictional force of contact-making surface to transmit moment; Two or many locating wedges 4 are put into the groove 5 of mandrel 1, stop the axial displacement of roller shell 2: positioning sleeve 3 is contained on the positioning step 7 after adding thermal expansion, firmly make up with mandrel 1 the cooling back, and the part of positioning sleeve 3 is blocked locating wedge 4, stops the radial displacement of locating wedge 4.
Compared with the prior art hot-mounted roll sleeve type combined roll of the present invention has the following advantages:
1. hot-mounted roll sleeve type combined roll does not have keyway, no screw thread, has reached the purpose that processing is simple, can bear big alternate stress;
2. adopt the induction coil local heat, reached purpose easy to loading and unloading;
3. positioning step on the mandrel 16,7 and detent 5 and locating wedge 4, positioning sleeve 3 actings in conjunction have reached roller shell service-strong purpose.
4. the roller shell 2 of hot-mounted roll sleeve type combined roll can be made of the high-alloy steel of high rigidity, also can make of high alloy iron, and the external diameter of roller shell can reach 300～600mm, and can improve more than 2 times the service life of roll, reduces cost 30%.
Be further described below in conjunction with accompanying drawing and embodiment:
Fig. 1 is the structural representation of hot-mounted roll sleeve type combined roll of the present invention.
Fig. 2 is the structural representation of hot-mounted roll sleeve type combined roll of the present invention.
Fig. 3 is the structural representation of hot-mounted roll sleeve type combined roll of the present invention.
Embodiment:
Embodiment 2: as shown in Figure 2, mandrel 1 usefulness 40Cr makes, the different roller shell 2 of diameter totally seven make with High-Hardness Cast Iron, 4 two of locating wedges are made with 45 steel, 3 one of positioning sleeves are made with 45 steel.The mandrel 1 of packing into after 2 heating of seven roller shells, two locating wedges 4 of in the annular groove 5 of mandrel 1, packing into then, the positioning sleeve 3 of on mandrel 1, packing into and having heated at last, and make the part of positioning sleeve 3 block locating wedge 4.After the cooling, the roll firm combination.This roll improves 3 times service life, is used for the rolling of channel-section steel.
Embodiment 3: as shown in Figure 3, a location step 6 is established in the centre of mandrel 1, and an annular groove 5 is respectively established at mandrel 1 two ends.Mandrel 1 usefulness 40Cr steel is made, and 2 two of roller shells are made with High-Hardness Cast Iron, and 4 four of locating wedges are made with 45 steel, and 3 two of positioning sleeves are made with 45 steel.At an end of mandrel 1 roller shell that has heated 2 of packing into, two locating wedges 4 of packing in annular groove are loaded onto a positioning sleeve that has heated 3; Then at the other end of mandrel pack in the same way a roller shell 2, two locating wedges 4, a positioning sleeve 3.Be used for rolling angle iron, roll improves 3 times service life.
