Description
Technical Field
The utility model relates to a disc spring type quick ejection device of a screw press, which can be widely applied to screw presses.
Background
The main problems of the existing ejection device on the screw press are that: the hydraulic upper ejection mode is generally adopted, and due to the influence of the temperature of the hot forging environment, the service life of a sealing ring of the hydraulic upper ejection device is extremely short, the conditions of insufficient upper ejection force, oil channeling and oil leakage are easily caused, the hydraulic upper ejection speed is low, the contact time of a workpiece and a die is long, and the service life of the die is seriously influenced. There are also mechanical link type upper ejection devices which are complex in structure, inconvenient to repair and maintain, and require professional technicians to repair and maintain.
Disclosure of Invention
The utility model aims to provide the disc spring type quick ejection device of the screw press, which has the advantages of simple structure, convenient maintenance, no influence of the temperature of the hot forging environment, high ejection speed, greatly shortened contact time between a die and a workpiece and effectively prolonged service life of the die.
In order to achieve the purpose, the disc spring type quick ejection device of the screw press comprises a sliding block with a step hole at the center of the bottom surface, a stop plate arranged close to the top surface of the step hole of the sliding block, a spring clamping groove at the lower part, a positioning guide sleeve arranged close to the bottom surface of the stop plate, a disc spring group arranged in the spring clamping groove of the positioning guide sleeve, a cross-shaped cylindrical ejector rod inserted into the inner holes of the disc spring group and the positioning guide sleeve and used for supporting the disc spring group, a step hole and an exhaust hole, a boss bottom surface close to the cross-shaped cylindrical ejector rod and a compression flange arranged on the sliding block through a fastening bolt.
The utility model relates to a disc spring type quick ejection device of a screw press, wherein disc spring groups are stacked in a involution mode.
The utility model relates to a disc spring type quick ejection device of a screw press, wherein an ejection mounting hole is formed in the bottom surface of a sliding block, a stop plate is arranged at the bottom of the mounting hole to protect the sliding block, a positioning guide sleeve is arranged at the lower part of the stop plate, a disc spring group is stacked in a involution mode, a round rod at the upper part of a boss of a cylindrical cross ejector rod penetrates through an inner hole of the disc spring group to enter a guide hole of the positioning guide sleeve, a round rod at the lower part of the boss of the cylindrical cross ejector rod penetrates through a central hole of a compression flange, and the compression flange is pre-tightened with the sliding block through bolts.
The utility model relates to a disc spring type quick ejection device of a screw press, which has the following working principle: when the screw press sliding block forges the workpiece, the screw press die cavity is closed, the cylindrical cross ejector rod compresses the disc spring group under the action of the forgeing force, the lower part of the cylindrical cross ejector rod is retracted to compress the central hole of the flange under the guiding action of the positioning guide sleeve, after the forgeing is finished, the screw press sliding block is lifted to drive the die cavity on the die to lift up instantly, and the cylindrical cross ejector rod is extended instantly to rapidly eject the workpiece out of the die cavity due to the counteractive disc spring force of the disc spring group, so that a working cycle is completed.
The utility model relates to a disc spring type quick ejection device of a screw press, which is characterized in that the impact force on a sliding block is reduced by the stop plate so as to protect the sliding block.
Compared with the prior art, the disc spring type quick ejection device of the screw press has the following beneficial effects: the die has the advantages of simple structure, convenient maintenance, no influence of the temperature of the hot forging environment, high ejection speed, capability of greatly shortening the contact time between the die and the workpiece and effectively prolonging the service life of the die.
