Clutch and electric compound transmission type pneumatic screw press with bottom dead center

Abstract

The invention provides a clutch-motor composite transmission type pneumatic screw press with a bottom dead center. The pneumatic screw press comprises a machine body, a screw rod, a lower carrying bearing mounted in a groove formed in the upper plane of a cross beam mounted on the machine body, a nut, an intermediate body, a nut gland, a middle carrying bearing, a main motor, a belt pulley, a big flywheel, an upper bearing, a friction plate, a friction disk type clutch, a pneumatic cylinder body, a cap-like annular piston, a reset spring, a reversible type reciprocating driving motor, a driving gear, a small flywheel, a sliding block, a bottom dead center buffer block mounted on a machine body base and balanced hoisting cylinders vertically mounted on the two sides of the machine body, and piston rods of the balanced hoisting cylinders are connected with extension bodies of the sliding block. The clutch-motor composite transmission type pneumatic screw press has the fixed bottom dead center and is reliable and safe in operation, friendly to environment and high in hitting speed. The die contact time is short. The die service life is long. The production efficiency is high. The unbalance load resistant capacity is high. Multi-position die forging is realized. The requirements for large energy and large hitting force are met. The clutch-motor composite transmission type pneumatic screw press can be extensively applied to the forging process of hot die forging forming.

Description

technical field [0001] The invention relates to a clutch and electric compound transmission type pneumatic screw press with a bottom dead point, which can be widely used in hot die forging forming forging technology. Background technique [0002] The existing screw press cannot meet the demand for large energy due to the small transmission ratio and short stroke. Generally, hydraulic control is adopted. If there is a deviation during processing, production and installation, it will cause oil leakage and other phenomena, endangering personal safety and causing environmental pollution. Secondly, because the equipment has no fixed bottom dead point, once the slider exceeds the bottom dead point during equipment use or maintenance, it will cause serious problems such as the separation of the screw and the slider, which will bring serious safety hazards to the equipment and staff. question.
