Embodiment Construction

[0056] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0057] figure 1 An embodiment of the heat exchange fin manufacturing machine of the present invention is shown. In the heat exchange fin manufacturing machine, a strip-shaped thin metal plate 10 is extended from a coil 12 and fed to a punching unit 18 , and a regulated tension or the like is applied to the strip-shaped metal plate 10 . In the punching unit 18, a plurality of ringed through-holes are formed in the strip-shaped metal plate 10 by a pair of punching dies. Then, the band-shaped metal plate 10 is cut with the cutter 26 of the punching unit 18 to form a plurality of elongated fin pieces having a prescribed width. The elongated fin members are fed sequentially to the air suction unit 14 . When feeding the elongated fin member to the suction unit 14 with a prescribed length, the cutter of the punching unit 18 cuts the elongated fin me...

Abstract

The tension device comprises: a feeding unit for feeding a band-shaped metal plate to a press unit; and a holding unit for applying tension to the band-shaped metal plate. The feeding unit is constituted by a moving member and a feeding pin. The front end of the feeding pin has a slope face so as to engage with a collared through-hole of the band-shaped metal plate when the moving member moves in a feeding direction of the band-shaped metal plate and so as to disengage therefrom when the moving member stops and moves in the reverse direction. The holding unit has a holding member, which holds and applies prescribed tension to the band-shaped metal plate when the moving member stops and which releases the band-shaped metal plate when the moving member starts to move in the feeding direction.

Description

technical field [0001] The present invention relates to a tensioning device and a heat exchange fin manufacturing machine, and more particularly to a tensioning device comprising a feeding unit and a holding unit for intermittently feeding a band-shaped metal plate to a punching unit to form a belt loop through hole thereon, and a holding unit for applying tension to a portion of the strip-shaped metal sheet between the feeding unit and the holding unit when the punching unit stops feeding the strip-shaped metal sheet to the punching unit, the present The invention also relates to a heat exchange fin manufacturing machine with a tensioning device. Background technique [0002] Heat exchange fins used in air conditioners etc. by e.g. Figure 6 Shown heat exchange fin manufacturing machine to manufacture. The heat exchange fins are formed by processing a band-shaped metal plate 10 made of, for example, aluminum. A strip of metal sheet 10 extends from a roll 12 . A strip-sha...
