SHEARING & PRESS AKE - KAWA HYDRAULIC PRESS AKE Frame : The frame is of heavy duty design and hot rolled welded steer plate construction. The shearing table is Integral wi e basic machine frame to ensure maximum rigidity. Ram and Guidance : Ram is so designed for minimum deflection, for parallelism of ram travel wiout servo / Hydro electronic etc. a pair of hydraulic cylinders are synchronized by a heavy duty torsion bar made from heavy walled steel tube. Welded to e levers result absolute parallelism between ram and table. Slide is so design wi brass liner fitted inside wi ram and runs on saddle perfectly housed wi frame. Pins, Pivots and Slide : All pins and bushes are made from alloy steel material wi hardened ground after machining for accurate
and long working life. All Pivots, pin, bushes and slides are lubricated by centralized hand operated lubrication systems. Hydraulic Cylinders : The Hydraulic Cylinder are made from high resistant steel wi chromium plated rod wi imported seal kit for perfect and long working life and is so design to change or replace e seal kits wiout any oer dismantling like ram tool etc. Tooling : Kawa K series Press Brake machine are equipped wi punch and die consist wi carbon steel material machined and ground but wiout hardened. Hardened and Ground standard Punch and Die Block or any special tooling can be offer as an optional. Power Pack Unit: : The low noise Hydraulic system is designed as per International practices and assembled wi internationally reputed make components. The Hydraulic valves are mounted on e especially compact designed manifold block to minimize of piping and to avoid any leakages. The large size oil reservoir is provided for adequate cooling and increase oil life. Operating Mode : The Kawa press brake machine is facilitate wi 3 working mode Inching, Single Stroke and Continuous operation, consist wi electrical hard wiring logic of electrical panel. Electrical panels & components are provided as per international reputed brands. Inching : This mode is used for setting blade angle dep stroke. The ram movement (up down) can be controlled at any described Position from foot switches. Auto : The cycle (Approach-Pressing-return) is continuously Repeated once is cycle is selected. This mode is useful for Continuous repetitive work where stroke leng can be adjusted to suit e job and e operators speed and rhym. Single : This mode is used for single operation. Air Bending : In air bending e dies are made at more of an acute angle (85 degrees or less) an angle to be formed. The only contact between e dies and e material occurs at e tip of male punch and e edges of e female die. The material is air bent raer an coined or bottom bent. The advisable Vee die openings for air bending are: V = 6 to 8 x material ickness(t), when t < 4 V = 6 to 12 x material ickness(t), when t < 4 Bottom Bending (Bottoming):
In bottom bending e upper and lower dies are usually made wi an included angle of 90 degrees to ensure sharp corners on e formed part. In e forming process, e dies strike solidly and squeeze e metal at stroke bottom. This process requires 3 to 5 times e tonnage needed in air bending. Since more tonnage is required bottoming is seldom performed on steel greater an 12 gauge. The advisable Vee die openings for Bottoming are V = 5 to 6 x material ickness Bottoming dies are made in matched pairs, according to e ickness and tensile streng of e stock to be formed and e radius needed. The upper and lower dies may require an included 88 or 89 degrees to overcome e spring back of materials wi high tensile streng.

The bending chart given on e next page covers all major bending for plates of 45 Kg/2 ultimate tensile streng. The figures given by e chart refer to 1 meter leng so ey must be multiplied by total plate leng to obtain e final required force in Metric Tonnes. odel os. 20 20 Tonnage Mt Bending Capacity ) In Ms UTS 45 Kg/2 Table Size ) Clear Passing ) Ram Strokes ) Open Height ) Closed Height ) Throat Dept ) Appro ach Ram Speeds /sec Pres sing Retu rn Motor (KW) HP Over all Dimensions 30 2X2000 1x2000 1700 100 280 180 200 30 7 30 (2.5)3 2200 1110 1750 00 40 2X00 1x2000 2000 100 280 180 200 50 6 50 (2.5)5 2650 10 1800 3000 50 2X2000 170x00 1500 100 280 180 200 48 6 48 (3.75)5 2200 1300 18 3000 50 2.5X00 3X00 (32 V ) Len g ) Wid ) Heig ) 170x00 2000 100 280 180 200 48 6 48 (3.75)5 2700 1300 18 3500 Wei
