Изобретение относитс к металлообработке и может быть использовано при модернизации горизонтальных ленточнь1х пил дл разрезани материалов, преимущественно панелей из алюминиевых сплавов.The invention relates to metalworking and can be used to retrofit horizontal band saws for cutting materials, mainly aluminum alloy panels.

Известна ленточна пила, включающа станину с направл ющими, несущими гидравлически перемещаемую пильную раму с пильной лентой, установленной на ведущем и направл ющем дисках, и гидроприжимы с балками, расположенными на станине 1.A known band saw includes a frame with guides carrying a hydraulically movable saw frame with a saw band mounted on the drive and guide discs, and hydraulic clamps with beams located on frame 1.

Недостатками данного устройства вл ютс низка точность разрезани и низкое качество поверхности крупногабаритных заготовок из-за больщих упругих смещений пильной ленты.The disadvantages of this device are low cutting accuracy and poor surface quality of large-sized workpieces due to the large elastic displacements of the saw band.

Поставленна цель достигаетс тем, что ленточна пила снабжена установленными на направл ющих станины механизмами прижима, выполненными в виде попарно соединенных подпружиненных стержней с балками, при этом одна из балок снабжена ос ми, сопр женными посредством амортизаторов с кронщтейнами, установленными на балке гидроприжима.The goal is achieved by the fact that the band saw is equipped with clamping mechanisms mounted on the guide beds, made in the form of pairwise connected spring-loaded rods with beams, while one of the beams is equipped with axles that are coupled by means of shock absorbers to the hydraulic clamp.

На фиг. 1 изображена ленточна пила, общий. вид; на фиг. 2 - вид А на фиг. 1; на фиг. 3 - разрез Б-Б на фиг. 2.FIG. 1 shows a band saw, common. view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. 2

Ленточна пила содержит станину 1 с направл ющими 2, в которых установлена гидравлически перемещаема пильна рама 3 с пильной лентой 4, установленной на направл ющем 5 и ведущем. 6 дисках. Пильна лента 4 в нижней части повернута вертикально с помощью направл ющих роликов 7, закрепленных на пильной ра10 ме 3. В направл ющих 8 и 9 станины 2 установлены с возможностью вертикального перемещени соединенные попарно в нижней части стержни 10 и 11, подпружиненные со стороны станины в сторонуThe band saw comprises a frame 1 with guides 2 in which a hydraulically movable saw frame 3 is installed with a saw band 4 mounted on the guide 5 and leading. 6 drives. The saw band 4 in the lower part is turned vertically with the help of guide rollers 7 mounted on the saw section 3. In the guides 8 and 9, the frame 2 is mounted with the possibility of vertical movement connected in pairs in the lower part of the rods 10 and 11, spring-loaded from the side of the frame the side

Claims

15 sawband 4 by springs 12, to which upper ends beams 13 and 14 are fixed with a gap between them for passing sawband 4. Axles 15 with heads 16 at the end are passed to the beam 14, passed into hole 17 of brackets 18 attached to beams 19 hydraulic clamps 20 Between the beam 14 and the brackets 18, shock absorbers 21 mounted on the axle 15 are mounted. The tape saw has a drive of 22 saw tape 4. The tape saw works as follows. The cut product is installed on the bed 1. Hydraulic clamp 20 clamp it. In this case, the bracket 18 acts through the shock absorbers 21 on the beam 14. The beams 13 and 14 are lowered onto the product being cut, they are also clamped. Then the saw frame 3 with the included drive 22 of the saw belt 4 is lowered down by means of hydraulic cylinders (not shown). The saw blade 4 passes into the gap between the beams 13 and 14, ensuring its direction along the cutting line. After the end of the cutting, the hydraulic clamps 20 are raised, while the beams 13 and 14 under the influence of the springs 12 and hydraulic clamps 20 also rise to the upper position. An invention of a band saw comprising a frame with guides carrying a hydraulically movable saw frame with a saw band mounted on the drive and guide discs, and hydraulic clamps with beams located on the frame, characterized in that, in order to improve the accuracy and reliability of cutting with a band saw with a large length of the cutting part of the saw band, the band saw is equipped with clamping mechanisms mounted on the guide beds, made in the form of pairwise connected spring-loaded rods with beams, with ohm odes of the beams is provided on the axles, conjugated by means of shock absorbers with brackets mounted on the beam gidroprizhima.
