Water stop sheet folding former

Abstract

The invention discloses a water stop sheet folding former, which relates to a device for producing a water stop sheet used in water-power engineering. The water stop sheet folding former comprises a feed positioning platform and a power device, wherein the power device is connected with a carrier gear; the carrier gear is connected with a feed roller set, upper flanging roller sets and lower flanging roller sets through a gear set; the feed roller set is arranged on a rack through a bearing block; the upper flanging roller sets are symmetrically arranged on two sides of the rack through bearing blocks; the lower flanging roller sets are correspondingly arranged under the upper flanging roller sets through bearing blocks; and an adjustable raised blade is arranged between rollers on the two sides. The water stop sheet folding former provided by the invention realizes the raised size of the water stop sheet in a certain range on the premise of ensuring the flanging quality, and does not need to replace a roller set die so as to improve the work efficiency and lighten the labor intensity.

Description

technical field [0001] The invention relates to a device for producing water-stop sheets used in hydropower projects, in particular to a folding forming machine for water-stop sheets by rolling. Background technique [0002] Chinese patent 200510018571.9 discloses a "concrete face dam water-stop copper sheet rolling forming machine", which produces water-stop copper sheets by rolling and forming the rolling wheel group, which has high production efficiency and is easy to use, avoiding the need for water-stop sheets The uneven thickness and easy torsion and thinning phenomenon avoid the waste of materials. The existing problems are: the weight of the equipment is heavy, the length is long, and it is inconvenient to move, hoist and adjust the posture according to the slope of the dam surface; different specifications need to be produced It is very troublesome to replace the mold of the rolling wheel when the water stop is used; the equipment adopts chain transmission, the work...
