Description

The roll-in device of chute

Technical field

The utility model relates to cold pressing roller technical field, is specifically related to the roll-in device of chute.

Background technology

Chute guide rail is the matching component on arrangements for automotive doors, and chute guide rail need to adopt cold rolling processing. Because chute is very narrow, processing has stone top layer with cold pressing roller, and cold pressing roller bears very large pressure wearing and tearing simultaneously, and cold pressing roller heating is larger. Therefore, the cold pressing roller on existing market exists after long-term use, and cold pressing roller can be due to the overheated shortcoming that occurs fatigue flake.

Summary of the invention

The utility model provides the roll-in device of chute, and the utility model has solved the cold pressing roller on existing market due to the overheated problem that occurs fatigue flake。

For addressing the above problem, the utility model adopts following technical scheme: the roll-in device of chute, comprises roller shell, roll body, the spindle nose of integrative-structure; Roll body is solid cylinder, and roller shell is positioned at roll body periphery, and roller shell and roll body junction are step-like and arc transition; Roll body two ends are fixedly installed shaft head structure, and the outer wall of spindle nose has annular groove, and roll body and spindle nose junction are step-like and arc transition; Roller shell periphery has louvre, has the heat radiation through hole of horizontally set in roll body, and heat radiation through hole two ends connect to two end faces of roll body, and louvre is communicated with heat radiation through hole; Louvre is manhole. The diameter of louvre is 1-3 millimeter. Have eight heat radiation through holes and be uniformly distributed on the same circumference of roll body end face, have eight row's louvres at roll body periphery, eight row's louvres are communicated with respectively eight heat radiation through holes.

Advantage of the present utility model: the utility model is provided with louvre on roller shell surface, be provided with the heat radiation through hole of horizontally set in roll body inside, can be in the time that cold pressing roller carries out repeatedly moulding compacting to chute guide rail, effectively the dissipation of heat of generation is gone out, overcome long-time use of cold pressing roller and there will be the shortcoming that occurs fatigue flake due to overheated, meanwhile, because chute guide rail need to carry out moulding press process repeatedly, therefore louvre can not exert an influence to detent surface shape.

Detailed description of the invention

With best embodiment, the utility model is described in detail below。

As shown in Figure 1-2, the roll-in device of chute, comprises roller shell 1, roll body 2, the spindle nose 3 of integrative-structure; Roll body 2 is solid cylinder, and roller shell 1 is positioned at roll body 2 peripheries, and roller shell 1 is step-like and arc transition with roll body 2 junctions; Roll body 2 two ends are fixedly installed spindle nose 3 structures, and the outer wall of spindle nose 3 has annular groove, and roll body 2 is step-like and arc transition with spindle nose 3 junctions; Roller shell 1 periphery has louvre 4, has the heat radiation through hole 5 of horizontally set in roll body 2, and heat radiation through hole 5 two ends connect to 2 two end faces of roll body, and louvre 4 is communicated with heat radiation through hole 5; Louvre 4 is manhole. The diameter of louvre 4 is 1-3 millimeter. Have eight heat radiation through holes 5 and be uniformly distributed on the same circumference of roll body 2 end face, have eight row's louvre 4, eight row's louvres 4 to be communicated with respectively eight heat radiation through holes 5 at roll body 2 peripheries.

In use, the heat that cold pressing roller comes out is delivered to heat radiation through hole 5 by louvre 4 to the utility model, then is delivered to the external world by heat radiation through hole 5, reaches the object that reduces cold pressing roller temperature, and cold pressing roller can be used for a long time. Because chute guide rail need to carry out moulding press process repeatedly, therefore louvre 4 can not exert an influence to detent surface shape.

The utility model provides the roll-in device of chute, the utility model solved the cold pressing roller on existing market after long-term use due to the overheated shortcoming that causes fatigue flake。

Finally it should be noted that: obviously, above-described embodiment is only for the utility model example is clearly described, and the not restriction to embodiment. For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description. Here without also giving exhaustive to all embodiments. And the apparent variation of being amplified out thus or variation are still among protection domain of the present utility model.
