Description
1 Technical parameters
2 The characteristics of this machine are as follows：
1) This machine adopts the overall frame plus tensioning bolts and pre-tensioning, which increases the stiffness of the fuselage.
2) The operation of the machine adopts manual operation method, which is sensitive and reliable.
3) In the lower part of the beam, there is a buffer device, which can buffer the collision and protect the equipment when the brake fails.
3 Structural features and working principle
This machine belongs to a traditional structural form of screw press, and its main feature is that the flywheel is driven by a friction mechanism. The transmission chain of the machine is composed of a first-stage belt drive, an orthogonal disc friction drive and a spiral slider mechanism. Its working principle is: the main motor drives the drive shaft to rotate in one direction through a V-belt (from the left side of the machine, it rotates counterclockwise), and the left and right friction discs mounted on the drive shaft rotate together with the drive shaft. When the joystick is pressed, the main shaft is moved axially by the lever system, and the friction wheel compresses the flywheel. Relying on friction, the flywheel is driven to rotate (from the top of the machine, it rotates clockwise), and the circular motion of the flywheel is transformed into the linear motion of the slider by a spiral mechanism. After the slider contacts the workpiece through the mold, all the energy accumulated by the flywheel and the slider in motion is released, and the moment of inertia of the flywheel is converted into the forging force of the slider on the workpiece through the spiral mechanism. When the forging is over, lift the control handle and press the flywheel together with the lever system, the right friction disc and the drive shaft. The flywheel rotates in reverse, the slider returns, and when the slider rises to a predetermined position, the handle returns to the middle position, so that the friction disc returns to the middle position, and the slider enters the braking stroke, which stops the slider at the set upper dead point. At this time, a work cycle of this machine is completed.
