Bending Machine Manual

We are a professional bending machine manufacturer with over 10 years of industry experience. Today, we would like to introduce you the difference between manual bending machine and CNC bending machine:

 

1, The basic concept and working principle

 

Manual bending machine is a traditional equipment through human operation of mechanical levers or hydraulic system, the pressure on the metal plate to complete the bending operation. The operator needs to manually adjust the position of the stopper, through observation and experience to control the bending angle. Its power source is mainly the operator's physical strength or a simple hydraulic power system.

 

CNC bending machine adopts computerized digital control system to realize precise bending by servo motor driving hydraulic system or electric servo mechanism. The operator only needs to input the processing parameters, and the machine automatically completes the positioning, pressure control and angle compensation. The system can store hundreds of machining programs for quick switching.

 

2, Structure and composition differences

 

The core structure of manual bending machine includes:

 

(1)Cast iron or steel body frame

 

(2)Manually adjustable mechanical stopping device

 

(3)Simple hydraulic system or purely mechanical transmission mechanism

 

(4)Angle scale and other basic measuring tools

 

Typical configurations of CNC bending machines include:

 

(1)Highly rigid welded machine body

 

(2)CNC control system and human-machine interface

 

(3)Servomotor-driven back stop mechanism

 

(4)Hydraulic proportional valve or electric servo drive system

 

(5)Angle real-time detection and feedback device

 

3,The operation mode comparison

 

The operation process of manual bending machine:

 

(1)Manually measure and adjust the blocking position

 

(2)Test bending through the angle ruler detection

 

(3)Repeatedly adjusted to meet the standards based on experience

 

(4)Continuous monitoring is required in mass production.

 

Operation characteristics of CNC bending machine:

 

(1)Call the preset program or input bending parameters

 

(2)The system automatically calculates and sets the blocking position.

 

(3)Continuous production after the first piece passes the test

 

(4)Automatic compensation of angular deviation during processing

 

4, Processing capacity analysis

 

Manual bending machine processing limitations:

 

(1)The maximum bending length is generally not more than 3 meters

 

(2)Plate thickness is usually limited to less than 3mm

 

(3)Angle control accuracy of about ± 1 ° -2 °

 

(4)Not suitable for complex multi-pass bending

 

Performance advantages of CNC bending machine:

 

(1)Handles long workpieces of 6 meters or more

 

(2)Maximum processing thickness up to 20mm

 

(3)Angular accuracy of up to ± 0.1 °

 

(4)Capable of complex multi-step molding

 

(5)Support asymmetric bending and other special processes

 

5, production efficiency comparison

 

Production characteristics of manual bending machine:

 

(1)Preparation time for a single piece is about 5-10 minutes

 

(2)Dependent on the operator's proficiency

 

(3)Suitable for small batch, multi-species production

 

(4)Daily output usually does not exceed 200 pieces

The efficiency performance of CNC bending machine:

 

(1)Program retrieval time is less than 30 seconds

 

(2)The average cycle time of a single piece is reduced by 50 percent

 

(3)Suitable for medium and large volume production

 

(4)Unattended continuous operation can be realized

 

6, Economic considerations

 

Cost characteristics of manual bending machine:

 

(1)Equipment procurement costs for CNC machine 1/5-1/10

 

(2)Maintenance is simple and inexpensive

 

(3)Lower technical requirements for operators

 

(4)Energy consumption is basically zero (purely mechanical)

 

Return on investment of CNC bending machine:

 

(1)Higher initial investment but long life cycle

 

(2)Requires specialized maintenance team support

 

(3)Operators need basic programming skills

 

(4)Lower cost per piece in the long run

 

7, Applicable Scenario Suggestions

 

Typical scenarios for selecting a manual bending machine:

 

(1)Maintenance workshop and other sporadic processing needs

 

(2)Educational institutions teaching demonstration purposes

 

(3)Start-ups are capital constraints stage

 

(4)Simple single bending operations

 

Recommended application scenarios for CNC bending machines:

 

(1)Professional sheet metal processing enterprises

 

(2)Mass production of automobile parts

 

(3)Scale manufacturing of chassis and cabinets

 

(4)Aerospace parts with high precision requirements

 

8, Technology development trend

 

The improvement direction of manual bending machine:

 

(1)The addition of simple digital display device

 

(2)Optimization of hydraulic power system

 

(3)Modular mold design

 

The technological evolution of CNC bending machines:

 

(1)Artificial intelligence process optimization

 

(2)3D simulation pre-bending technology

 

(3)Internet of Things remote monitoring

 

(4)Adaptive learning compensation system

 

9, Safety precautions

 

(1)Manual bending machines need to focus on prevention:

 

(2)Mechanical pinch risk

 

(3)Workpiece rebound danger

 

(4)Fatigue operating errors

 

CNC bending machine safety management points:

 

(1)Photoelectric protection device effectiveness

 

(2)Program misoperation prevention

 

(3)Area control in automatic mode

 

Enterprises should be based on the actual production needs, capital budget and technical basis for a reasonable choice of equipment type. For a single product, accuracy requirements are not high occasions, manual bending machine still has economic advantages; and in the face of multi-species, high-precision, high-volume production needs, CNC bending machine will significantly improve the quality and efficiency. The two types of equipment is not a complete substitute for the relationship between the specific conditions can be complementary use. It is recommended to conduct a full process evaluation and costing before purchasing, and if necessary, consider a phased upgrade program.
