Abstract

The invention discloses an electric screw press, belongs to forging forming equipment, solves the problem that a slider is long and has a small travel in the conventional electric screw press, and is used for producing clay bricks, refractory bricks, common die forgings and precision die forgings. The electric screw press comprises a press body, a main gear, a nut, a screw, a slider body, an ejection cylinder, a left motor, a right motor, a front brake cylinder and a rear brake cylinder; and a left piston cylinder and a right piston cylinder which are bilaterally symmetrical are fixed in the press body. The nut and the main gear are tightened and rotate under the drive of the left and right motors; and the screw and the slider body are connected into a whole and driven by the nut to linearly move vertically, the screw can extend out of the upper end face of the main gear, the length of the slider body is consistent with or is even less than the height of a slider of a friction screw press with the same nominal pressure and body dimensions, the travel of the slider body can be increased by more than 100mm, the hammering energy of the slider body is correspondingly increased, and the application range can be widened obviously.

Description

technical field [0001] The invention belongs to forging and pressing forming equipment, which is used for the production of clay bricks and refractory bricks, common die forgings and precision die forgings. Background technique [0002] There are existing electric screw presses at home and abroad. The motor is driven by a first-stage gear, that is, a pinion is installed on the motor shaft. The motor drives the flywheel and the screw connected with the flywheel through the pinion to rotate. The nut on the block makes the slider move up and down in a straight line to realize the forging function; the flywheel can be driven by multiple motors through the pinion at the same time, so the specification can be made very large. At present, the world's largest tonnage reaches 320MN, which is far larger than other die Tonnage of forging equipment. See Xiong Xiaohong et al., "CNC Electric Screw Press", Forging Technology, 2007, vol.32, NO.5: 110-113; Zhang Yuanliang et al., "Research ...
