Digital Control and Intelligent Application--In-depth Analysis of HOWFIT DDH 400T ZW-3700 Electronic Control System
Share to : 
Introduction
With the continuous progress of science and technology, digital control is more and more widely used in modern industry, especially in equipment such as punching machines, the importance of digital control is more and more prominent. In this paper, we will discuss the application of digital control and intelligent application in the electronic control system of HOWFIT DDH 400T ZW-3700 high-speed precision punching machine, as well as its impact on the improvement of the degree of intelligence and production efficiency.
Electronic control system design
HOWFIT DDH 400T ZW-3700 adopts the design of stand-alone electric control box + mobile operating station and eight groups of batch control, which not only makes the press have a higher degree of intelligence, but also improves the production efficiency. The structure of stand-alone electric control box + mobile operation desk makes operation more convenient, while the eight groups of batch control enables the press to carry out multiple processes at the same time, which greatly improves the production efficiency.
Safety System Analysis
As a powerful production equipment, the safety of the press is of utmost importance. DDH 400T ZW-3700 is equipped with safety light grating and front and rear safety gate devices, which are designed to guarantee the safe operation of the press. The safety encoder monitors the safety zone around the press and stops the system as soon as it detects the entry of a person or object, ensuring the safety of the operator. The front and rear safety gates provide a physical barrier to prevent people from accidentally entering the work area while the press is in operation, thus further enhancing operational safety.
