Abstract
The utility model relates to a kind of thin-wall circular and describes device hemmer, comprise the compression roller be pressed in the cylinder outer end edges of High Rotation Speed, the outer circumference surface of described compression roller is provided with the annular groove with required crimping mating shapes, the position that the inner limit of cylinder is relative with described compression roller is arranged and the carrying roller of annular groove mating shapes on compression roller, to make in turn-up process compression roller and carrying roller from common extrusion cylinder end limit, the both sides on cylinder end limit.Remain that relative position is constant at turn-up process middle idler roller and compression roller, cylindrical shell end limit produces distortion along the gap between compression roller and carrying roller, therefore alleviates the excessive scratching of roller groove to overlay, has also contained the generation of gauffer simultaneously.
Description
Technical field
The utility model relates to a kind of device of machining, and especially a kind of thin-wall circular describes device hemmer.
Background technology
Traditional thin-wall circular describes flange, the flanging process of device, and as shown in Figure 1, thin cylinder 1 High Rotation Speed in figure, compression roller 2 is pressed on the end limit of cylinder 1, and presses down gradually, forces cylinder 1 end limit according to the distortion of compression roller 2 groove shape, completes flange.But when carrying out flange to PCM, VCM color steel, because surface of steel plate scribbles polyester layer, very easily causing coating scratch and easily cause gauffer 5 in turn-up process, having a strong impact on the quality of flange.
Utility model content
Problem to be solved in the utility model is to provide in a kind of turn-up process can not cause coating scuffing and be not easy to draw crimped thin-wall circular describes device hemmer.
For solving the problems of the technologies described above, thin-wall circular of the present utility model describes device hemmer, comprise the compression roller be pressed in the cylinder outer end edges of High Rotation Speed, the outer circumference surface of described compression roller is provided with the annular groove with required crimping mating shapes, the position that the inner limit of cylinder is relative with described compression roller is arranged and the carrying roller of annular groove mating shapes on compression roller, to make in turn-up process compression roller and carrying roller from common extrusion cylinder end limit, the both sides on cylinder end limit.Compression roller is from while the extruding of the outside of cylinder, and the carrying roller matched with annular groove shape extrudes from the inner side of cylinder, better can make that cylinder end limit is rolled and coat does not produce fold.
Improve as one, described carrying roller and compression roller are obliquely installed.Carrying roller and compression roller inclination certain angle, the effect of extruding can be better.
Preferably, described carrying roller and extrusion roll shaft between inclination angle be 20 degree-40 and spend.
Improve as one, described carrying roller is arranged on the elevating mechanism that can move up and down relative to cylinder.After flange completes, carrying roller departs from cylindrical shell, is convenient to cylindrical shell and takes out.
After adopting such structure, thin-wall circular of the present utility model describes at turn-up process middle idler roller and compression roller, device hemmer remains that relative position is constant, cylindrical shell end limit produces distortion along the gap between compression roller and carrying roller, therefore alleviate the transition scratching of roller groove to overlay, also contain the generation of gauffer simultaneously.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation that in prior art, thin-wall circular describes device hemmer.
Fig. 2 be thin-wall circular of the present utility model describe device hemmer overturning process start before schematic diagram.
Fig. 3 is the schematic diagram of thin-wall circular of the present utility model when describing that device hemmer overturning process carries out.

Detailed description of the invention
As shown in Figure 2, Figure 3 and Figure 4, thin-wall circular of the present utility model describes device hemmer, comprise the compression roller 2 be pressed in cylinder 1 outer end edges of High Rotation Speed, the outer circumference surface of compression roller 2 is provided with the annular groove 3 with required crimping mating shapes, the position that the inner limit of cylinder 1 is relative with described compression roller 2 is arranged and the carrying roller 4 of annular groove 3 mating shapes on compression roller 2, to make in turn-up process compression roller 2 and carrying roller 4 from the common extrusion cylinder 1 end limit, both sides on cylinder 1 end limit.Compression roller 2 is from while the extruding of the outside of cylinder 1, and the carrying roller 4 matched with annular groove 3 shape extrudes from the inner side of cylinder 1, better can make that cylinder 1 end limit is rolled and coat 5 does not produce fold.Inclination angle between carrying roller 4 and compression roller 2 axis is 20 degree-40 and spends.Carrying roller 4 is arranged on the elevating mechanism 6 that can move up and down relative to cylinder.After flange completes, carrying roller 4 departs from cylindrical shell 1, is convenient to cylindrical shell 1 and takes out.
Before overturning process starts, the position on compression roller 2 and carrying roller 4 and cylinder 1 end limit as shown in Figure 2, when starting flange, compression roller 2 and carrying roller 4 move in a direction indicated by the arrow, as shown in Figure 3, cylinder 1 High Rotation Speed, cylinder 1 edge is out of shape in the gap between compression roller 2 and carrying roller 4.After cylindrical shell flange completes, cylindrical shell stops the rotation, and carrying roller 4 moves in a direction indicated by the arrow, as shown in Figure 4, is convenient to cylindrical shell and takes out.
Claims (4)
