The invention relates to an open type direct-drive electric screw press, wherein a direct-drive motor is a switched reluctance motor.
The invention relates to an open type direct-drive electric screw press, which has the working principle that: the direct-drive motor drives the lower rotating body to rotate and drives the upper rotating body and the flywheel which are connected with the lower rotating body into a whole to rotate, so that the screw rod is driven to rotate, the sliding block is driven to move downwards under the action of the screw rod and the screw nut pair, the forging is struck by means of energy generated by the moving system, and when a die on the sliding block is in contact with a workpiece, one-time striking is completed. After the striking is finished, the direct drive motor rotates in a reversing way, and the screw rod rotates reversely to drive the sliding block to move upwards in a straight line. When the sliding block returns to the preset stroke distance, the friction block type brake presses the flywheel to complete braking, so that the sliding block is stopped at the initial position, and a working cycle is completed.
The open type direct-drive electric screw press adopts the direct-drive motor to directly drive, directly transmits the torque to the screw, has no intermediate transmission link of belt transmission or gear transmission, does not need an intermediate transmission chain, and has the advantages of simplified structure, less parts and simple structure, thereby having short transmission chain.
The open type direct-drive electric screw press is energy-saving due to the fact that the transmission chain is short, the number of easily-damaged parts is small, and the energy loss is small.
Compared with the traditional indirect drive electric screw press, the open type direct drive electric screw press has the advantages that the response speed is high, the transmission efficiency is improved by more than 20 percent, and therefore, the transmission efficiency is high.
The open type direct-drive electric screw press disclosed by the invention has the advantages that the defect of short service life of a traditional motor and a traditional gear is overcome due to the fact that a belt transmission or gear transmission intermediate transmission chain is not adopted, and therefore, the transmission reliability is high.
The open type direct-drive electric screw press has the advantages that the movement noise is greatly reduced because the open type direct-drive electric screw press does not have an intermediate transmission chain link, and therefore, the noise is low.
The open type direct-drive electric screw press adopts an open type machine body structure, is arranged on an open type workbench, is convenient to install a die, has large space, and is easy to realize automatic production.
The invention relates to an open type direct-drive electric screw press, wherein a direct-drive motor is a reversible motor and performs reversing motion in the positive and negative directions.
The open type direct-drive electric screw press is directly driven by the direct-drive motor, and does not need to increase primary belt transmission or gear transmission compared with an indirect-drive electric screw press; compared with a friction screw press, the friction screw press does not need a rotating cross shaft, a friction disc and two support arms; compared with a hydraulic screw press, no complex and demanding hydraulic system is required. Therefore, the device has the advantages of few parts, simple structure, small equipment volume, stable action, small transmission noise, short transmission chain, easy manufacture, light weight, convenient installation and low manufacturing cost.
