In order to solve the problems of the prior art, the utility model provides a kind of roller nail to protect the removable roller of roller press of tooth with limit, avoids the excessive wear of roller surface, improves the service life of running roller, reduces rehabilitation expense.
In order to achieve the above object, the technical solution adopted in the utility model is:
Roller of roller press, the surface of described running roller is provided with several roller nails, and the place, surperficial both sides of the edge of described running roller is respectively provided with a row limit and protects tooth; The surface of described running roller is provided with several and follows closely the roller nail hole of matching with described roller, and described roller is followed closely correspondence one by one and is fixedly installed in described roller nail hole; The end face of described running roller and the surperficial intersection of described running roller are provided with several and protect with described limit the limit that tooth matches and protect perforation, described limit protect tooth one by one correspondence be fixedly installed on described limit and protect in perforation.
Further, described roller nail is fixedly connected with by gluing mode with described roller nail hole.
Further, bottom, described roller nail hole is arcuate bottom.
Further, one end of described roller nail is that tack, the other end are round end.
Further, the gap between described roller nail and described roller nail hole is 10 μ m～60 μ m.
Further, the surperficial open-minded hole communicating with described rectangular wedge groove that perforation comprises the rectangular wedge groove of the end face that is arranged on described running roller and is arranged on described running roller is protected on described limit.
Further, described limit is protected tooth and is protected perforation with described limit and be fixedly connected with by gluing mode.
Further, to protect the gap of tooth and described limit protecting between perforation be 10 μ m～60 μ m on described limit.
Compared with prior art, the technique effect that the technical solution adopted in the utility model produces is:
The utility model protects roller nail and limit from tooth by gluing mode and is fixed on running roller, when roller nail and limit are protected odontotripsis and are changed to needs, by the mode of heating running roller, tooth can be protected in the roller nail of wearing and tearing and limit extracts from running roller, tooth is protected on the roller nail and the limit that more renew, thereby avoid the surface of running roller to be worn, extended the service life of running roller; It is short repair time that more the shutdown of tooth is protected on roll change nail and limit, and rehabilitation expense is low.
Accompanying drawing explanation
The structural representation of the roller of roller press that Fig. 1 provides for the utility model embodiment;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are described in detail.
As depicted in figs. 1 and 2, the utility model embodiment provides a kind of roller of roller press, the surface 1 of running roller is provided with several roller nails 3,1 place, both sides of the edge, surface of running roller is respectively provided with a row limit and protects tooth 2, two row limits are protected between tooth 2 and are uniformly distributed many row's roller nails 3, and the magnitude setting of roller nail 3 is selected according to roll squeezer specification.The surface 1 of running roller is provided with several roller nail holes of matching with roller nail 3, and roller nail 3 is corresponding to be one by one fixed in roller nail hole by gluing mode, and the gap between roller nail and roller nail hole is 10 μ m～60 μ m.The end face 4 of running roller and surface 1 intersection of running roller are provided with several and protect with limit the limit that tooth 2 matches and protect perforation, limit protect tooth 2 by gluing mode one by one correspondence be fixed on limit and protect in perforation, it is 10 μ m～60 μ m that the gap of tooth and limit protecting between perforation is protected on limit.Particularly, the open-minded hole 6 communicating with rectangular wedge groove 5 that perforation comprises the rectangular wedge groove 5 of the end face 4 that is arranged on running roller and is arranged on the surface 1 of running roller is protected on limit, and the opening of rectangular wedge groove 5 is towards the end face 4 of running roller.
Further, bottom, described roller nail hole is arcuate bottom.Arcuate bottom adds the contact area of big roller nail and bottom, roller nail hole on the one hand, is difficult for crushing roll nail bottom margin when pressure at right angle is large; Guarantee on the other hand larger cement plane, make cementing more firm of roller nail.One end of described roller nail is that tack, the other end are round end, according to material requirement, determines to be by tack or round end is exposed.
Further, the material of roller nail is according to material difference, and the chrome molybdenum tungsten nickel material that can adopt hardness and wearability to take into account, meets need of production.
Further, limit is protected tooth and is comprised of upper and lower two parts, and the material of bottom is chrome-moly steel, the material on top is carbide alloy, upper and lower two parts connect by welding and bolt, have both guaranteed that limit protected the wearability of tooth, have significantly reduced again the material cost that tooth is protected on limit.
Assembling of the present utility model and repair process are as follows:
First, by the inserting paragraph gluing of roller nail 3, insert in roller nail hole, knock in rubber hammer; Then limit is protected to tooth 2 gluings and driven in from the rectangular wedge groove 5 of running roller end face 4, limit is protected the part that tooth 2 exposes roller surface 1 and is leant out from the hole 6 of slitting.When roller nail 3 and limit are protected tooth 2 and be may wear to a certain degree, replaceable roller nail 3 protects tooth 2 with limit, and roller surface 1 is not worn.When needs are pulled down roller when nail, with cutting torch baking roller nail hole roller surface around, because glue-line produces gas after being heated, roller screw top can be gone out, with pliers, extract roller nail subsequently.
Compared with prior art, tool has the following advantages the utility model:
(1) roller nail material can be for material difference, and the chrome molybdenum tungsten nickel material that adopts hardness and wearability to take into account, meets need of production, and need not consider welding factor.
(2) to protect tooth material be chrome-moly steel and carbide alloy on limit, by welding and bolt, connect two parts are combined, both guaranteed that limit protects the wearability of tooth, significantly reduced again the material cost that tooth is protected on limit, it is also by cementing combination that limit protects that tooth and limit protect between perforation, is convenient to change.
(3) roller nail glueds joint combination with roll surface employing, when roller nail may wear to a certain degree, can dismantle roller nail by warm-up mill wheel surface, to realize more roll change nail, can not make roll surface be worn, and shutdown is very short repair time; Owing to not needing to repair roll surface, rehabilitation expense is very low.
(4) roller nail and limit are protected the tooth life-span and are generally 6-10 month, on more roll change nail and limit, protect under the condition of tooth, and running roller can not wear and tear, and the life-span of running roller can reach more than 60 months.
Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model the utility model.Like this, if within of the present utility model these are revised and modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model is also intended to comprise these changes and modification interior.
