Abstract
The utility model discloses a kind of tube bending machine roll wheel assembly, comprise and support pedestal and be located at the back shaft supporting on pedestal, on back shaft, be set with without oily lining, on without oily lining, be set with nylon roller, nylon roller with without oily lining, be interference fit, this tube bending machine forms by the structure of roll wheel assembly abandoning tradition roll wheel assembly, adopt copper alloy without oily lining as sliding bearing to substitute rolling bearing, make its longer service life in adverse circumstances; Roller adopts nylon material to make simultaneously, the roller that alternative original carbon steel is material, make it when with tube fraction, be unlikely to steel pipe to fray, the utility model roll wheel assembly is simplified the structure of traditional roll wheel assembly, quick and easy for installation, more traditional roll wheel assembly longer service life, is subject to the impact of working environment little, reliable operation simultaneously.
Description
Technical field
the utility model relates to tubing technical field of processing equipment, particularly a kind of for the roll wheel assembly on tube bending machine.
Background technology
the charging and discharging roll wheel assembly of existing tube bending machine is mainly comprised of roller and bearing two parts, wherein roller portion adopts carbon steel material to make mostly, and be positioned at inner bearing, conventionally adopt rolling bearing, in use, during due to steel pipe material forming, exist a large amount of oxide skin to come off, work under bad environment, the oxide skin coming off easily enters in rolling bearing, causes that bearing blocks or damages; Meanwhile, because roller portion is carbon steel material, while rubbing with steel pipe, easily cause steel tube surface to scratch, cause quality accident.
Utility model content
Technical problem to be solved in the utility model is to provide the tube bending machine roll wheel assembly of a kind of simple in structure, long service life, reliable operation.
For solving the problems of the technologies described above adopted technical scheme: a kind of tube bending machine roll wheel assembly, comprise and support pedestal and be located at the back shaft supporting on pedestal, on described back shaft, be set with without oily lining, described, be set with nylon roller on without oily lining, described nylon roller with without oily lining, be interference fit.
Further, described is that copper alloy is without oily lining without oily lining.
Further, describedly without oily lining flangikng, form shoulder, the recess that the shoulder of being and not being oil lining matches is established at described nylon roller middle part, at described back shaft two ends, is provided with gland to support the shoulder without oily lining.
Beneficial effect: this tube bending machine forms by the structure of roll wheel assembly abandoning tradition roll wheel assembly, adopt copper alloy without oily lining as sliding bearing to substitute rolling bearing, make its longer service life in adverse circumstances; Roller adopts nylon material to make simultaneously, the roller that alternative original carbon steel is material, make it when with tube fraction, be unlikely to steel pipe to fray, the utility model roll wheel assembly is simplified the structure of traditional roll wheel assembly, quick and easy for installation, more traditional roll wheel assembly longer service life, is subject to the impact of working environment little, reliable operation simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further;
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
With reference to Fig. 1, a kind of tube bending machine roll wheel assembly of the utility model, comprises and supports pedestal 1 and be located at the back shaft 2 supporting on pedestal 1, is set with without oily lining 3 on back shaft 2, on without oily lining 3, be set with nylon roller 4, nylon roller 4 with without oily lining 3, be interference fit.
In the present embodiment, what without oily lining 3, adopt is that copper alloy is without oily lining, without oily lining 3 be two respectively symmetry be arranged on back shaft 2 both sides, back shaft 2 with without oily lining 3, are matched in clearance, assurance can flexible rotating, nylon roller 4 with without oily lining 3 interference fit formation one, between nylon roller 4 in both sides and support pedestal 1, to leave gap, while guaranteeing to roll, be not in contact with one another each other friction, as preferably, in the flangikng without oily lining 3, form shoulder, the recess that the shoulder of being and not being oil lining 3 matches is established at nylon roller 4 middle parts, the axial location that realizes roller that coordinates by nylon roller 4 recesses with shoulder without oily lining 3, at back shaft 2 two ends, be provided with gland 5 to support the shoulder without oily lining 3 simultaneously, prevent from deviating from without oily lining 3.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken possessing at described technical field those of ordinary skill, can also under the prerequisite that does not depart from the utility model aim, make various variations.
Claims (3)
