Vertical multi-link toggle cold (warm) extruder Product application: Vertical multi-link toggle cold (warm) extruder is suitable for cold or warm extrusion of metal billets.Product performance characteristics: 1. Multi-link toggle mechanical motion mechanism.The mechanism has a larger extrusion stroke, 25-80 mm; the nominal force stroke is longer, 20-48 mm.2. The speed of the sliding block gradually slows down between the nominal force strokes, which reduces the speed of the mold contacting the workpiece and prolongs the service life of the mold.3. When the slider travels, the extrusion force gradually increases between the nominal force strokes. When the slider travels to the bottom dead center, the extrusion force reaches about 1.5 times the nominal force (commonly known as a booster press), and there is a pressure holding time of about 0.35 seconds. This ensures the plastic deformation of the metal blank when it is cold extruded, reduces the deformation and rebound of the extruded product when it is discharged, and makes the grain structure of the product denser.4. The sliding block and the pendulum rod are connected by the guide post and guide sleeve structure to reduce the lateral force; the shape and strength of the relevant components are adjusted by finite element analysis to enhance the rigidity of the bed; the main parts adopt high-precision machining technology; the transmission pair adopts thin oil force Lubrication technology, high machine precision.5. Equipped with a high-slip variable frequency speed-regulating motor; a flywheel with a high energy storage wedge-shaped belt groove is designed, and the driving force of the machine tool is strong, which is suitable for extruding ferrous metals.6. The number of working strokes is divided into different speeds and grades to meet the extrusion forming requirements of different products, and the upper and lower ejection devices are designed with high strength and strength, which is conducive to the ejection of products.Main technical parameters: Project unit value (JA89-315) Value (JA89-630) Value (JA89-1250) Nominal force KN 3150 6300 12500 Nominal force stroke mm 16 38 58 Extrusion stroke mm 25 50 68 Slider stroke mm 340 420 520 Slider stroke times min-1 36 28 15-24 Maximum die height mm 500 800 1000 Die height adjustment mm 15 15 15 Slider bottom surface size (front and rear*left and right) mm 700*700 900*900 1250*1000 Working Platen size (front and rear*left and right)) mm 900*850 1050*1050 1250*1000 Worktable thickness mm 160 350 300 Main motor power Kw 45 90 132 Upper ejection force KN 160 320 500 Upper ejection stroke mm 35 70 75 Under the top material force KN 315 630 1250 under the top material stroke mm 60 160 180
