Description
Technical Field
[0001] This utility model relates to the field of hydraulic press technology, and in particular to a servo motor drive system. Background Technology
[0002] A hydraulic press is a device that uses specialized hydraulic oil as its working medium and a hydraulic pump as its power source. The pump forces the hydraulic oil through hydraulic lines into a cylinder or piston. Inside the cylinder or piston, there are mating seals that separate the hydraulic oil at different locations, creating varying pressures. These pressures are then transmitted to other actuators to achieve different process flows. The working principle of a hydraulic press is to use a hydraulic pump to convert the mechanical energy of an electric motor into the pressure energy of a liquid. This pressure energy is then transmitted through a series of control elements to the actuator, where it is further converted into mechanical energy to drive the load. In a hydraulic press, the hydraulic oil serves as both the energy transfer medium and a lubricant and coolant.
[0003] However, existing hydraulic presses have oil leakage issues with their hydraulic components and cylinders' relative moving surfaces, requiring regular maintenance and inspection, which increases maintenance costs. Furthermore, the complex structure of hydraulic presses makes it difficult to detect problems in a timely manner. The hydraulic drive system has a relatively complex structure, requiring the sequential disassembly of multiple components such as the hydraulic pump, hydraulic cylinder, and oil pipes, making installation and maintenance quite difficult.

[0024] In this embodiment, the driving gear 4 and the driven gear 12, in cooperation with the chain 13, drive the connecting assembly 10 to move, while the connecting mechanism drives the platform 9 to move up and down; the two support assemblies 2 are used for limiting and supporting the main drive shaft 1 in the horizontal direction, and can adjust the main drive shaft 1 to keep it in a horizontal state, thereby driving the chains 13 on both sides to move up and down smoothly and evenly; the servo motor 7, in conjunction with the reducer 5, can reduce vibration and noise, achieve higher precision, save unnecessary output, and improve production efficiency.
[0025] Furthermore, the two support components 2 are respectively located between the two drive boxes 6, and the reducer 5 is located between the two support components 2.

The support components 2 not only prevent deformation of the main drive shaft 1 due to excessive length, but also adjust and maintain it in an absolutely horizontal state, thereby ensuring that the kinetic energy transmitted on both sides is the same. The servo motor 7 and the reducer 5 work together to generate kinetic energy, which is transmitted through the main drive shaft 1 to the drive box 6, driving the drive gear 4 in the drive box 6 to rotate. Chain 13 passes through the drive box 6 fixed on the bracket 3 and drives the driven gear 12. The connecting assembly 10 connects the two ends of the chain 13, and the spacing of the chain 13 is adjusted to ensure that the chain 13 is vertical, so that the table 9 can be connected into a whole through the chain 13. After the program is set for the servo motor 7, the servo motor 7 drives the main drive shaft 1 to rotate. The main drive shaft 1 transmits kinetic energy to the chain 13 through the drive gear 4. The chain 13 drives the connecting assembly 10 to move up and down, thereby driving the table 9 to move up and down.
[0036] In this utility model, the design can reduce the space required for product installation while ensuring maintenance space is available, thereby reducing overall costs. It also makes it easier to identify problems, greatly saving manpower and resources. At the same time, it is simple to operate and not prone to damage, thus reducing safety hazards and after-sales maintenance costs.
