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.

DDH 400T ZW-3700 Machine Features

1. three-section combination structure, twice the nominal force tensioning, good overall rigidity, deflection value control in 1/18000, to ensure the long-term stable operation of the punch press.

2. high-quality alloy castings, after stress relief treatment, excellent vibration damping performance, to ensure long-term accuracy.

3. key castings after finite element analysis, reasonable force, small deformation.

4. The slider adopts pre-stressed eight-face circular needle roller guide to ensure the perpendicularity and parallelism of the up and down movement of the slider, and improve the mold production cycle and durability.

5. reverse symmetry dynamic balancing device, balance the horizontal and vertical inertia force generated during operation, to ensure the smooth operation of the machine.

6. the connecting rod and six-point super close support part adopts high-speed and heavy-duty sliding bearing structure, which ensures the precision of the lower dead point and the stability in the stamping process.

7. large oil volume thin oil lubrication device, effectively take away the heat generated in the process of operation, to ensure the stability of the whole machine under the dead point precision.

8. airbag type static balance device, to ensure smooth operation, and in the die height adjustment of the transmission parts of the wear and tear of the effective control, improve the die adjusting mechanism.
