Compact Heavy Plate Bending Press for 20mm Carbon Steel Short

ZYCO

1.This type of press brake utilizes a single-cylinder design, which simplifies the hydraulic system and results in a more compact overall structure that occupies less workshop space. Additionally, the reduced number of components lowers both procurement and maintenance costs, making it an ideal choice for projects with limited workspace or flexible budget requirements.

2.Due to the short working bed (typically around 1 meter in length) and the high rigidity of the ram, the concentrated force from the single cylinder is evenly distributed across the entire ram. This ensures synchronized downward movement at both ends, resulting in stable and reliable bending precision.

3.For "short, thick plates," the single-cylinder structure offers the advantage of direct force output. Precise control is achieved via electro-hydraulic servo or pump-controlled servo systems, enabling stable bending of short, thick plates while ensuring consistent bending angles.

Control system

The E21 system is a dual-axis CNC controller designed specifically for economical press brakes; it meets both the machine's CNC functional requirements and precision control standards.

It supports the storage of 40 programs, with each program allowing for up to 25 steps, enabling the processing of complex workpieces in a single run and significantly boosting production efficiency.

Equipped with a high-definition LCD screen, it displays all programming parameters on a single page, ensuring intuitive and convenient operation.

Tooling

To form 20mm thick plates, the V-opening of the bottom die is typically sized at 8–10 times the plate thickness (e.g., V > 160mm) to prevent material cracking and accommodate the immense tonnage requirements.

The tooling itself is massive and heavy; it undergoes processes such as CNC deep-case hardening to achieve a high hardness of HRC 56–60, with a hardened layer depth of up to 4mm, enabling it to withstand repeated impacts of hundreds of tons.

Back gauge

Utilizes a ball screw paired with a servo motor to achieve high rigidity, rapid response, and micron-level repeatability.

The backgauge beam is constructed from high-strength steel with an optimized cross-sectional profile to resist deflection, ensuring long-term precision stability.

Reducer

The reducer is a core component of the press brake's drive system; its precision directly determines the machine's stability and accuracy.

It efficiently transmits power from the motor to the actuating mechanism with minimal energy loss.
