Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of profile of tooth shaped device; This device comprises framework 201, profile of tooth molding roller 202, level and smooth roll 203, and described profile of tooth molding roller 202 is rotationally connected by drive shaft and described framework 201, and described level and smooth roll 203 is rotationally connected by drive shaft and described framework 201.Described profile of tooth molding roller 202 is arranged at the top of described level and smooth roll 203, and the plane be connected between the central shaft of described profile of tooth molding roller 202 with described level and smooth roll 203 central shaft and described metal belting 101 perpendicular.In the utility model, adopt described profile of tooth molding roller 202 to be arranged at above described level and smooth roll 203, be, when facilitating described high-frequency welding, easily see gap clearly like this; Described profile of tooth molding roller 202 also can be arranged at the below of described level and smooth roll 203 in fact, is not limited to above-mentioned set-up mode.
As shown in Figure 1 and Figure 2, described profile of tooth molding roller 202 comprises profile of tooth molding roller body 204 and is arranged at the side roll 205 of described profile of tooth molding roller body 204 both sides; The periphery of described profile of tooth molding roller body 204 is provided with many spiral-shaped helicla flutes 206, is provided with boss 207 between described helicla flute 206; The two ends of described profile of tooth molding roller body 204, be provided with the ring-shaped groove 208 (for whole profile of tooth molding roller 202, ring-shaped groove 208 is symmetricly set in the two ends of profile of tooth molding roller 202) around outer circumference surface with the boudary portion of described side roll 205.
Preferred: the two ends of described helicla flute 206 are crossing with the described ring-shaped groove 208 of described profile of tooth molding roller body 204 both sides respectively.
As shown in Figure 3, the effect of ring-shaped groove 208 is: by profile of tooth molding roller 202 on metal belting 101 along the both sides of the edge of metal belting and the first protruding muscle 003 that had the position of certain distance to roll out and the second muscle 004, first muscle 003 and the second muscle 004 are formed in the total length of metal belting 101.In this implementation process, the state of the cross section of ring-shaped groove 208 can be level and smooth circular shape also can be triangle.
The outer circumference surface at the middle part of described profile of tooth molding roller body 204 is the positive face of cylinder (the positive face of cylinder is relative and taper seat, and its external diameter is constant).Described profile of tooth molding roller body 204 is taper seat at the outer circumference surface of the two side portions of axis direction and is the taper seat towards the reduced diameter on roll 205 direction, described side.Therefore, the thickness of the metal belting 101 at spiral grooves 006 two ends is set to increase progressively towards the direction of the first muscle 003 and the second muscle 004: be also that the wall thickness of the described metal tube 001 in described first area 02 thickeies along with the minimizing of the distance between described first muscle 003; The wall thickness of the described metal tube 001 in described 3rd area 04 thickeies along with the minimizing of the distance between described second muscle 004.
The degree of depth of described helicla flute 206 reduces gradually towards the two ends of described profile of tooth molding roller body 204, and in addition, the boss 207 for profile of tooth molding roller body 204 carries out chamfering with the edge of helicla flute 206 whether can.Therefore, with the height of the helical tooth 005 on the metal belting 101 of roll roll forming, along with the trend just presenting minimizing close to the first muscle 003 of projection and the second muscle 004.
The outer circumference surface of described molding roller is circular cone profile, and the outer circumference surface of described molding roller reduces along axis direction gradually towards outside external diameter.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
