Abstract
A direct drive crank press comprises a press body, a crank arranged on a press body hole, a connecting rod arranged on the middle part of the crank, a sliding block arranged on the connecting rod, a flywheel arranged on the other end of the crank and used for storing and releasing energy, a brake arranged on the side surface of the press body and used for braking the outer circular surface of the flywheel, a rotor provided with a flange plate and arranged on the flywheel through a fastening bolt, a motor support arranged on the side surface of the press body, and a direct drive motor arranged on the motor support and directly driving the rotor to rotate. The direct drive type crank press has the advantages of short transmission chain, simple structure, few parts, small equipment volume, light weight, simple installation, easy manufacture, low manufacturing cost, stable transmission, high forging precision, low noise, convenient maintenance, long service life and remarkable energy saving. Can be widely applied to the forging forming process of the forge piece.
Description
Technical Field
The invention relates to a direct drive type crank press which can be widely applied to the forging forming process of forgings.
Background
In the existing crank press, a motor drives a crank to rotate through belt transmission or gear transmission, namely a transmission chain is arranged in the middle. The structure is complicated and the cost is high. Due to the existence of the intermediate transmission chain, the forming precision of the forged piece is low.
Disclosure of Invention
The invention aims to provide a direct-drive crank press which has the advantages of short transmission chain, simplified structure, less parts, small equipment volume, light weight, simplicity in installation, easiness in manufacturing, low manufacturing cost, stability in transmission, high forging precision, low noise, convenience in maintenance, long service life and remarkable energy saving.
In order to achieve the purpose, the direct drive crank press comprises a press body, a crank arranged in a hole of the press body, a connecting rod arranged on the middle part of the crank, a sliding block arranged on the connecting rod, a flywheel arranged on the other end of the crank and used for storing and releasing energy, a brake arranged on the side surface of the press body and used for braking the outer circular surface of the flywheel, a rotor provided with a flange and arranged on the flywheel through a fastening bolt, a motor support arranged on the side surface of the press body, and a direct drive motor arranged on the motor support and directly driving the rotor to rotate.
The invention relates to a direct-drive crank press, which has the working principle that: the direct-drive motor directly drives the rotor to rotate, the rotor drives the flywheel connected with the rotor to rotate, the flywheel drives the crank to rotate, and the crank drives the sliding block to move downwards through the connecting rod to realize forging and forming of the forge piece; after striking, the energy of the flywheel and the rotor is completely released, the crank is driven by the direct-drive motor to rotate upwards in a reverse direction, the sliding block is lifted to a preset height, the direct-drive motor is powered off, the brake brakes the flywheel, the sliding block is stopped at an initial position, and a working cycle is completed.
Compared with the prior art, the direct drive type crank press is directly driven by the direct drive type motor, and belt transmission or gear transmission intermediate transmission is reduced, so that the direct drive type crank press is short in transmission chain, simple in structure, few in parts, small in equipment size, light in weight, easy to manufacture and low in manufacturing cost.
Compared with the traditional technology, the direct drive type crank press is directly driven by the direct drive type motor, and belt transmission or gear transmission is omitted, so that the direct drive type crank press is stable in transmission, high in forging precision, reduced by more than 20dB compared with the traditional crank press, and low in noise. Meanwhile, because the direct drive motor and the flywheel do not idle, when forging and pressing are not carried out, noise can be completely avoided.
The direct drive type crank press has the advantages of simple transmission mode, reduced maintenance amount, labor force and maintenance cost saving, and convenient maintenance and repair, thereby being convenient for maintenance. And the loss of parts is small, and the service life is long.
Compared with the traditional crank press, the direct drive crank press has the advantages that the drive motor of the traditional crank press always rotates to drive the flywheel to rotate, the flywheel rotates for inertia, and the clutch controls the sliding block to move. The direct-drive motor drives the press, the direct-drive motor does not need to rotate all the time, the direct-drive motor only rotates when the press is formed and started, the flywheel idles and consumes energy, the flywheel stores and releases energy, and the energy consumption of the clutch is reduced due to the absence of the clutch. Therefore, the energy is saved by more than 50 percent, and the energy is saved remarkably.
In conclusion, the direct drive type crank press has the advantages of short drive chain, simple structure, few parts, small equipment volume, light weight, simplified installation, easy manufacture, low manufacturing cost, stable drive, high precision of forged pieces, low noise, convenient maintenance, long service life and remarkable energy saving.
