Abstract
The utility model discloses a kind of hard alloy roll, comprise the supporting-point roller with annular groove being arranged on outside rotating shaft, in described annular groove, be inlaid with carbide alloy abaculus, in described rotating shaft and described supporting-point roller, be provided with the cooling duct that is communicated with described annular groove, the inwall in the both sides of described carbide alloy abaculus along described annular groove is respectively arranged with sealing ring.The utility model compared with prior art, can solve existing hard alloy roll because High Rotation Speed is overheated, easily pulls the problem of carbide alloy workpiece.
Description
Technical field
The utility model relates to CEMENTED CARBIDE PRODUCTION equipment technical field, especially a kind of roll for processing rigid alloy.
Background technology
The existing roll for processing rigid alloy comprises the supporting-point roller being arranged on outside rotating shaft, and the outer peripheral axial plane of supporting-point roller is provided with for the fixing annular groove of carbide alloy abaculus.High temperature because roll produces when running up, easily causes sizing on the surface of carbide alloy workpiece, pulls workpiece, and pull-up groove, reduces the precision of workpiece, and impact is used, and also greatly reduces the service life of roll simultaneously.The processing enterprise of many carbide alloy also attempts at the first cooling roll of each first being processed water, temperature while turning round to reduce, owing to can not continue the processing contact-making surface of breaker roll and carbide alloy workpiece in process, carry out coolingly, still can not effectively improve overheated problem of pulling surface of the work.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of hard alloy roll, to solve existing hard alloy roll because High Rotation Speed is overheated, easily pulls the problem of carbide alloy workpiece.
In order to address the above problem, the technical solution of the utility model is: this hard alloy roll comprises the supporting-point roller with annular groove being arranged on outside rotating shaft, in described annular groove, be inlaid with carbide alloy abaculus, in described rotating shaft and described supporting-point roller, be provided with the cooling duct that is communicated with described annular groove, the inwall in the both sides of described carbide alloy abaculus along described annular groove is respectively arranged with sealing ring.
In technique scheme, more specifically scheme can be: the water inlet of described cooling duct and delivery port are located at respectively the two ends of described rotating shaft, described cooling duct is by the intake tunnel being communicated with successively, the first interface channel, the first groove, the second interface channel, circular passage, the 3rd interface channel, the second groove, the 4th interface channel and exhalant canal form, described intake tunnel extends inwardly to the middle part of described rotating shaft vertically from described water inlet, described the first interface channel stretches out and is communicated with the first groove between described rotating shaft and described supporting-point roller from the end footpath of described intake tunnel, the periphery of described circular passage is communicated with described annular groove, the inner side of described circular passage connects respectively described the second interface channel and described the 3rd interface channel, the other end of described the second interface channel is connected with described the first groove, the other end of described the 3rd interface channel is communicated with the second groove between described rotating shaft and described supporting-point roller, described exhalant canal extends to described delivery port from the middle part of described rotating shaft, the two ends of described the 4th interface channel are connected with described exhalant canal with described the second groove respectively.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
This hard alloy roll arranges cooling pipe by inside, and this cooling pipe leads to the annular groove of the fixedly carbide alloy workpiece outside the supporting-point roller of roll, make can the flow through contact-making surface of roll and workpiece of cooling water, can significantly reduce the temperature of roll and workpiece, avoid roll and surface of the work to pull because of overheated, thereby improved surface quality and the precision of hart metal product; Can also reduce significantly the damage of roll, greatly extend the service life of roll simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail:
This hard alloy roll as shown in Figure 1, it comprises the supporting-point roller 3 being arranged on outside rotating shaft 2, the outer peripheral axial plane of supporting-point roller 3 is provided with for the fixing annular groove 5 of carbide alloy abaculus 10.In rotating shaft 2 and supporting-point roller 3, be provided with the cooling pipe through annular groove 5.The water inlet 1 of described cooling duct and delivery port are located at respectively the two ends of rotating shaft 2, described cooling duct is by the intake tunnel 7 being communicated with successively, the first interface channel 8, the first groove 9, the second interface channel 11, circular passage 12, the 3rd interface channel 13, the second groove 14, the 4th interface channel 15 and exhalant canal 16 form, intake tunnel 7 extends inwardly to the middle part of rotating shaft 2 vertically from water inlet 1, the first interface channel 8 stretches out and is communicated with the first groove 9 between rotating shaft 2 and supporting-point roller 3 from the end footpath of intake tunnel 7, the periphery of circular passage 12 is communicated with annular groove 5, the inner side of circular passage 12 connects respectively the second interface channel 11 and the 3rd interface channel 13, the other end of the second interface channel 11 is connected with the first groove 9, the other end of the 3rd interface channel 13 is communicated with the second groove 14 between rotating shaft 2 and supporting-point roller 3, exhalant canal 16 extends to delivery port 6 from the middle part of rotating shaft 2, the two ends of the 4th interface channel 15 are connected with exhalant canal 16 with the second groove 14 respectively.Cooling water flows in whole cooling pipe, this cooling pipe leads to the annular groove 5 of the fixedly carbide alloy abaculus 10 outside the supporting-point roller 3 of roll, the contact-making surface of roll and carbide alloy abaculus 10 so that cooling water can be flowed through, can be constantly cooling in the process of carbide alloy abaculus 10.Annular groove 5 is provided with sealing ring 4 for one week along described cooling pipe.
