Drive system applicable to large-tonnage servo direct-driven hot die forging press

Abstract

Disclosed is a drive system applicable to a large-tonnage servo direct-driven hot die forging press. The drive system comprises four sets of drive mechanisms and two sets of actuating mechanisms. The drive mechanisms are in multilateral layout, each set of the drive mechanism comprises a servo motor, an output shaft of each servo motor is connected with a large belt wheel through a small belt wheel and a drive belt, the outer side of each large belt wheel is connected with a brake, and the inner side of each large belt wheel is connected with an input shaft of a planetary gear reducer. Two sets of toggle link mechanisms are adopted as the actuating mechanisms, each set of toggle link mechanism is composed of a crank, a triangular connecting link, an upper toggle link and a lower toggle link which are connected, output ends of the four planetary gear reducers are connected with two ends of the two cranks respectively, one end of each triangular connecting link is directly sleeved on the corresponding crank, the upper end of each triangular connecting link is connected onto an upper crossbeam of the hot die forging press through the corresponding upper toggle link, and the lower end of each triangular connecting link is connected with a slider through the corresponding lower toggle link and a guide plunger type connecting link. By the drive system, torque needed for forging can be lowered remarkably, the requirement on motor power is lowered, and bearing capacity and working efficiency of the hot die forging press are improved.

Description

technical field [0001] The invention belongs to the technical field of servo direct-drive hot die forging press manufacturing, and in particular relates to a transmission system suitable for a large-tonnage servo direct drive hot die forging press. Background technique [0002] The servo direct-drive hot die forging press can realize servo control of the forging process, and is an advanced forging equipment that realizes hot forming of metal blanks by means of molds. Various hot forging processes of metal profiles such as ordinary die forging, eccentric die forging and extrusion can be completed on hot forging presses. Hot die forging presses are commonly used die forging equipment in industrial production. With the rapid development of my country's machinery industry, the demand for high-performance forgings is increasing. At the same time, the requirements for energy saving, servoization and precision of die forging equipment are getting higher and higher. At present, th...

Problems solved by technology

However, since large flywheels and clutches are no longer used, current servo presses have high requirements for motor power and torque. If the original transmission system is not improved and the servo motor is directly used, the cost of the press will increase significantly

Due to the limitation of servo motor technology, the power of the servo motor that can be put into use is relatively small, which is far from meeting the requirements of the current large-tonnage hot die forging press for the direct drive of the servo motor

In addition, the price of the servo motor is expensive, and the greater the power of the servo motor, the higher the price, which has caused many manufacturers to dare not choose high-power servo motors in actual production.

At present, for large-tonnage hot die forging presses, many technicians have spent a lot of energy on researching the transmission system to reduce the press's demand for high-power servo motors, but with little success
