Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] This embodiment provides an electric screw press, such as figure 1 and figure 2 Shown, comprise fuselage 1, motor 16 of even number, screw rod 5, slide block 2 and the inertial wheel that outer ring is gearwheel 10, four guide rails 34 are arranged on fuselage 1, slide block 2 can be made along fuselage guide rail 34 Reciprocating linear motion. The nut 8 is connected with the fuselage 1 as a whole through the flange 6 and the key 7, and the screw rod 5 and the nut 8 are threaded. The lower end of screw rod 5 is equipped with thrust bearing 3, and cooperates with slide block 2 through bearing 4. The screw rod 5 drives the slider 2 to move linearly by forming a helical pair with the nut 8 . The inertia wheel is composed of disk 9, gear wheel 10, friction block 11, wheel hub 12, bolt 13, spring 14 and positioning ring 15, and the inertia wheel...

Abstract

The invention relates to the field of mechanical industrial equipment and particularly relates to an electric screw press which comprises a machine body, motors with an even number, a screw rod, a slide block and an inertia wheel with an outer ring as a large gear, wherein the motors are installed on the machine body, an extension shaft of each motor is provided with a small gear, the screw rod is connected with the inertia wheel to form a whole body and carries out linear motion by forming a spiral auxiliary drive slide block with a nut, each small gear is meshed with each large gear through a transition gear shaft, each transition gear shaft is installed on a swinging arm through a lower bearing and an upper bearing, each swinging arm is installed on a support arm through a pin shaft, and a pair of swinging arms which are symmetric around the rotation center of each large gear are connected together by a pull rod through a pull rod pin shaft. According to the invention, a novel electric screw press is manufactured and a friction screw press in the traditional structure can be reformed into the electric screw press.

Description

technical field [0001] The invention relates to the field of mechanical industrial equipment, in particular to an electric screw press. Background technique [0002] The electric screw press with a screw diameter less than 560 mm described in the German Muller-Weingarten company sample adopts the direct drive mode of the motor, the stator of the motor is fixed on the top of the press frame, and the rotor of the motor is the inertia wheel of the press. It is necessary to prepare a dedicated motor for each type of press machine, so the manufacturing difficulty is relatively large and the manufacturing cost is relatively high. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide an electric screw press that can reduce manufacturing costs. It uses a motor to drive the inertia wheel to rotate through gear reduction, and the screw pair converts the rotation of the inertia wheel to the linear motion of the slid...
