Busbar processing machines are key equipment in the power and electrical industry for cutting, punching, and bending metal busbars such as copper and aluminum bars. Standardized operation procedures and strict safety precautions directly affect processing efficiency and personnel safety. As a core step in manufacturing equipment like electrical cabinets and transformers, busbar processing requires precise parameter settings and standardized operating procedures to ensure busbar dimensions meet design requirements, while avoiding safety accidents caused by mechanical failures or operational errors. This article explains key equipment operation points systematically from two aspects: breakdown of operation procedures and safety risk prevention and control.

I. Standardized Operation Procedures: Three-Phase Control from Preparation to Finished Product

1. Pre-processing Preparation Phase

Before operation, inspect the equipment power supply, hydraulic system, and mold condition. For example, confirm that the hydraulic oil level is within the standard scale to avoid unstable pressure due to insufficient oil; check that the punching mold is securely installed to prevent mold detachment during processing, which may damage the equipment. Meanwhile, adjust equipment parameters (such as punching pressure and bending angle) according to the busbar material (copper/aluminum) and thickness, and verify parameter accuracy through trial processing.

2. Core Processing Phase

Busbar processing generally includes three processes: cutting, punching, and bending.

- For cutting: Place the busbar flat on the workbench, input length parameters via the CNC system, then start the cutting module.

- For punching: Select the corresponding mold per drawing requirements and ensure the busbar is aligned with the mold center.

- For bending: Adjust the bending radius based on busbar thickness to avoid busbar breakage caused by over-bending. For instance, when processing a 6 mm thick copper bar, the bending radius is recommended to be set to more than twice the busbar thickness.

3. Finished Product Inspection and Equipment Maintenance

After processing, measure busbar dimensions with a vernier caliper, check whether punching edges are smooth and bending angles meet design requirements. Meanwhile, clean metal debris from the equipment surface, and regularly add lubricating oil to moving parts such as guide rails and lead screws to extend service life.

Warning

Keep hands clear while the machine is in motion.

II. Safety Risk Prevention and Control: Dual Protection from Environment to Behavior

1. Equipment Safety Protection

Busbar processing machines must be equipped with photoelectric sensors, emergency stop buttons, and protective guards.

- Photoelectric sensors automatically stop the machine when detecting a human body or foreign object entering the danger zone.

- Emergency stop buttons should be installed on the operation panel and both sides of the equipment to quickly cut off power in emergencies.

- Protective guards must cover dangerous areas such as punching and bending zones to prevent injuries from flying metal chips.

For example, an operator was scratched by flying copper chips due to lack of a protective guard in a company; after installing the guard, similar accidents were eliminated.

2. Standardized Operating Behavior

Operators must wear protective clothing, anti-smash safety shoes, and goggles. Gloves are prohibited during operation (to prevent gloves from being caught in rotating parts).

- Never put hands into the mold area during processing.

- Power must be cut off and a "Do Not Switch On" sign hung when replacing molds or adjusting equipment.

- For multi-person collaborative work, clear command signals shall be defined to avoid misoperation due to poor communication.

3. Environmental Safety Requirements

The equipment shall be placed in a dry, ventilated indoor environment, away from flammable and explosive materials.

Regularly inspect the hydraulic system for aging oil pipes to prevent fires caused by hydraulic oil leakage.

For example, in a workshop, a broken hydraulic oil pipe was not handled in time, causing oil to seep into the motor and trigger a short circuit, eventually resulting in equipment burnout.

Operation and safety control of busbar processing machines shall run through the entire equipment life cycle. Every link—from standardized operation procedures to detailed safety protection—is related to processing quality and personnel safety. Enterprises can establish a systematic safety management system by regularly organizing operation training, setting up equipment maintenance files, and posting safety warning signs. For new employees, on-the-job mentoring by experienced workers is recommended to ensure they are familiar with equipment performance before independent operation.
