VIBRATION SUPPRESSING APPARATUS OF FORGING HAMMER

摘要

FIELD: plastic working of metals, possibly in percussion-action machines. ^ SUBSTANCE: under anvil bed of hammer cylinder is arranged. Piston of said cylinder is rigidly joined through rod with anvil bed. Cylinders whose pistons whose pistons are rigidly joined with trough rods with struts of hammer housing are arranged under said struts. All cylinders are secured to metallic frame of foundation. Upper cavity of cylinder arranged under anvil bed of hammer is communicated with atmosphere. Upper cavities of cylinders arranged under struts of housing and lower cavity of cylinder arranged under anvil bed are filled with liquid and mutually communicated through ducts. Lower cavities of cylinders arranged under struts are communicated with pneumatic main pipeline and with atmosphere through inlet and outlet controlled valves. ^ EFFECT: improved efficiency of suppressing vibration of working forging hammer transferred to ground. ^ 1 dwg
