Vertical forging press LZK 1000 – 1600
Vertical forging press LZK is used for production of precise die forgings with utilization in the automotive industry, for hot and semi-hot forging with forming forces of 10-65 MN, with high stiffness and extensive diagnostics, including modern, precise and solid fixtures and other extensive equipment.
Frame is casting from one piece of casting steel, it is thermaly treated for eliminating of the material tension. His firm box design does not ask for using of anchors. Ram is casting from one piece of alloyd steel for castings. The leading of ram in laths of the frame has shape „O“. Ram adjustment is driven by a hydraulical mechanism and i tis controlled by buttons from controlling panel. Countershaft is placed in the upper part of the frame on the right side in the sliding bearings. Countershaft is placed in upper part of the frame on right side in sliding bearings.
The press is equipped by multi-plate frictional clutch, which is controlled by electropneumatical valve. The press is equipped by multi-plate frictional brake also, which is controlled by electropneumatical valve. Used frictional material is asbestosless. The press is equipped with upper pneumatic and lower hydraulic ejectors. Power of the lower hydraulic ejector is 800 kN with stroke 60 mm.
The lower hydraulic ejector conducts 5 stroke per minute with maximal power. Power of the upper pneumatic ejector is 130 kN with stroke 50 mm. Basic span of pegs of both ejectors is 380 mm. The press is equipped with an automatical independent oil circulatory lubricating system of sliding bearings of crank mechanism and with an automatical independent fatty lubricating system of laths of ram guiding and of die holder. Hydraulic system of the press is utilized only for ram adjustment. Pneumatical system of the press works with the air pressure from the distribution system of the forging plant.
