Description

Automatic screw press convenient to maintain

Technical Field

The invention relates to the technical field of presses, in particular to an automatic screw press convenient to maintain.

Background

The die forging piece is widely applied to the industrial fields of automobiles, aviation, national defense and the like, in recent years, the requirement on the precision of the die forging piece is higher and higher, the die forging process is developed towards the precision forming direction, and a die forging hammer and a hot die forging press which are used for producing the die forging piece in the past cannot meet the requirement. The screw press is known to be an optimal forging device for performing precision die forging on parts such as blades and the like by virtue of good force performance characteristics, and is an ideal forming device for powder forming products. As a die forging device, compared with a die forging hammer, a hot die forging press and the like, the screw press has the advantages of simple structure, convenience in use and maintenance, wide process application range and the like, is a general name of a press machine which generates a pressurizing form by rotating more than one group of outer bolts and inner bolts in a frame, and basically consists of a flywheel, a screw rod, a nut, a sliding block and a machine body. The flywheel is accelerated and rotated through a transmission device such as friction, hydraulic pressure or direct drive of a motor, energy is accumulated, meanwhile, the rotation motion of the flywheel is converted into the up-and-down linear motion of the sliding block through a screw pair, and the accumulated energy is released at the end of a down-going segment, so that the workpiece is promoted to be formed. According to the nature of the forming force, the forming force can be divided into two categories, impact force and static pressure. The screw press is usually referred to mainly as impact force and works like a hammer, and is therefore also called a screw press. Screw presses are also known as friction presses, the largest friction press in china being 25 mn, because the flywheel is typically rotated by an electric motor driving a flywheel rim through a friction disc. The electric screw press has the characteristics of lower noise during operation, higher striking frequency, accurate control of striking energy and the like compared with screw presses in other forms such as friction presses, hydraulic screw presses and the like, so that the electric screw press is widely applied to manufacturing industries such as automobiles, high-speed railway locomotives, aerospace and the like, and is novel universal die forging equipment. When the sliding block contacts with the workpiece, the flywheel is forced to decelerate to stop completely, the stored rotational kinetic energy is converted into impact energy, and the workpiece is hit by the sliding block to be deformed. After the striking is finished, the motor enables the flywheel to rotate reversely, and the sliding block is driven to ascend and return to the original position. The specification of the screw press is expressed in terms of nominal working force. The screw press is forging equipment using screw and nut as transmission mechanism to transfer flywheel energy. In actual work of the existing electric screw press, when a nut drives a sliding block to move downwards, a large impact force is applied to a pressed workpiece, the force acts on the workpiece to deform the workpiece, but the workpiece is metal, the impact force is transmitted to a die table below, vibration and energy loss are caused, and the machine is possibly damaged due to long-time vibration.
