Twin-screw electric screw press

Abstract

A double-screw electric screw press comprises a rack, a slider mounted on a rack guide rail, a left copper nut, a right copper nut, a left screw, a right screw, a left gear-type flywheel, a right gear-type flywheel, four motors, left driving gears, right driving gears, a left flywheel brake, a right flywheel brake and a return cylinder. The left copper nut and the right copper nut are mounted in the slider in an embedded manner. The left screw and the right screw both mounted on the rack are mounted on the left copper nut and the right copper nut respectively. The left gear-type flywheel and the right gear-type flywheel are mounted at the upper ends of the left screw and the right screw respectively. The motors are vertically mounted on the rack. Two left driving gears and two right driving gears are mounted on the output shaft of each motor. The left flywheel brake and the right flywheel brake are positioned above the left gear-type flywheel and the right gear-type flywheel respectively and mounted on the rack. The return cylinder is mounted in the rack and on the slider. The double-screw electric screw press is small in screw diameter, easy to produce, large in equipment size, high in unbalance loading capacity, large in working table top, multiple in impression and stamp forging, high in transmission efficiency, good in energy-saving effect, simple in structure, few in part, short in transmission chain, small in part loss, low in cost, simple to operate and convenient to maintain, and can be widely applied to a forging and stamping forming industry.

Description

technical field [0001] The invention relates to a twin-screw electric screw press, which can be widely used in forging and pressing forming industries. Background technique [0002] Existing electric screw presses are all single-screw structures, and the ability of the slider to withstand eccentric loads is poor, so it is not suitable for multi-cavity die forging. For large-scale presses, the diameter of the screw is large, and it is difficult to hoist, transport and manufacture, which restricts the development of large-scale electric screw presses. Contents of the invention [0003] The purpose of the present invention is to provide a screw with small diameter, easy manufacture, large-scale equipment, strong anti-eccentric load capacity, large working table, multi-cavity die forging, high transmission efficiency, good energy-saving effect, simple structure, few parts, Twin-screw electric screw press with short transmission chain, small loss of parts, low cost, simple ope...
