Abstract
The utility model provides a kind of thermal treatment feeding roller rod, comprise cylindrical roll surface and grind coating with the increasing being sprayed on roll surface, cylindrical roll surface is square hatching knurling, comprise and two move towards groove and square projection, groove trend and roller rod axially angle at 45 °, the difference angle moved towards between groove is 90 °, a diagonal lines of square projection is axially parallel with roller rod, another diagonal lines is axially vertical with roller rod, the spray material increasing the use of mill coating is WC-TiC-Co cemented carbide powder, and the method for spraying is thermospray.The utility model, by increasing roller rod skin friction force, overcomes the deficiency that prior art causes feed rate slow because of the little skidding of frictional force, improves reinforced efficiency.
Description
Technical field
The utility model relates to a kind of roller rod, particularly a kind of for the feeding roller rod in thermal treatment feeding unit.
Background technology
Feed roller rod is a kind of common components in roller-way streamline, uses roller rod that the blank process that circulates can be made to become more smooth, guarantees carrying out smoothly of thermal treatment process.Present feed roller rod is all be made by heat-resisting steels, smooth surface, no matter is adopt hand-fed, or automatically feed in raw material, all can affects feed rate in reinforced process.And along with using the increase of duration, its surface flatness can be increasing, makes heat treatment efficiency step-down.
Current hot-spraying techniques is widely used, and hot-spraying techniques comprises flame plating, oxygen second flame spray welding, HVOF (High Velocity Oxygen Fuel), electric arc spraying, plasma spraying, air plasma spraying, low-voltage plasma spraying etc.Adopt hot-spraying techniques body material unrestricted, it can be metal and nonmetal, can spray on various body material, hot-spraying techniques can be used to spray nearly all solid engineering materials, operating procedure is flexible, do not limit by workpiece shapes, easy construction, coat-thickness can from 0.01 to several millimeters.In addition, hot-spraying techniques flow process is simple, saves tooling cost.
Utility model content
In view of the above in prior art due to roller rod smooth surface, cause material transferring difficulty, be not easy to control, the deficiency of wasting manpower and material resources, the utility model provide a kind of surface be carved with annular knurl roller rod.
For achieving the above object and other relevant objects, the utility model provides a kind of feeding roller rod.
A kind of thermal treatment feeding roller rod, comprise cylindrical roll surface and grind coating with the increasing being sprayed on described roll surface, cylindrical roll surface is square hatching knurling, comprise and two move towards groove, with square projection, described groove trend and roller rod axially angle at 45 °, the difference angle moved towards between groove is 90 °, a diagonal lines of described square projection is axially parallel with roller rod, another diagonal lines is axially vertical with roller rod, the described spray material increasing the use of mill coating is WC-TiC-Co cemented carbide powder, and the method for spraying is thermospray.
As preferably, the groove shapes on described thermal treatment feeding roller rod is semicircle, and the degree of depth is 3 ~ 8mm.Avoid material in fill process to remain in inside grooves, cause the waste of material.
As preferably, the groove of described thermal treatment feeding roller rod is circumferentially evenly distributed, and its spacing is 2 times of depth of groove.
As preferably, the granularity of described WC-TiC-Co cemented carbide powder is between 200 ~ 500 orders.
As preferably, described thermal treatment feeding roller rod surface increases the thickness of mill coating at 100 ~ 300 μm.
Groove and the increasing mill coating on the utility model roller rod surface reduce surface smoothness, increase the frictional force between roller rod surface and material, make fill process more smooth and easy, also avoid the waste of material to a certain extent, improve working efficiency.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is shown as the thermal treatment feeding roller rod Facad structure schematic diagram of the utility model embodiment.
Fig. 2 is shown as the enlarged view of A in Fig. 1.
Fig. 3 is shown as the thermal treatment feeding roller rod bottom construction partial view of the utility model embodiment.
Piece mark explanation
1,2 grooves,
3 projections.
Embodiment
Below by way of specific specific examples, embodiment of the present utility model is described, those skilled in the art the content disclosed by this specification sheets can understand other advantages of the present utility model and effect easily.The utility model can also be implemented or be applied by embodiments different in addition, and the every details in this specification sheets also can based on different viewpoints and application, carries out various modification or change not deviating under spirit of the present utility model.
A kind of thermal treatment feeding roller rod with reference to the accompanying drawings shown in 1, comprising cylindrical roll surface and grind coating with the increasing being sprayed on described roll surface. cylindrical roll surface is square hatching knurling, comprise and two move towards groove 1,2, with square projection 3, groove trend and roller rod axially angle at 45 °, the difference angle moved towards between groove is 90 °, and a diagonal lines of square projection 3 is axially parallel with roller rod, another diagonal lines is axially vertical with roller rod, refers to accompanying drawing 2.The spray material increasing the use of mill coating is WC-TiC-Co cemented carbide powder, and the method for spraying is thermospray.The groove of thermal treatment feeding roller rod is circumferentially evenly distributed, and its spacing is 2 times of depth of groove.
With reference to the accompanying drawings shown in 3, the groove shapes on thermal treatment feeding roller rod is semicircle, and the degree of depth is 5mm.Prevent material from remaining among groove, avoid waste.
In addition, the granularity of thermal treatment feeding roller rod surface increasing mill coating WC-TiC-Co cemented carbide powder is being 300 orders.
In addition, thermal treatment feeding roller rod surface increases the thickness of mill coating is 200 μm.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
