What Is Notching Machine? Types, Features & Operation

What is notching machine?

Notching machine is a kind of equipment for cutting metal plates.

Notching machine are divided into angle adjustable and non adjustable types.

Adjustable angle range: 40 ° ~ 135 °.

It can be adjusted arbitrarily within the angle range to achieve the ideal state.

What Is Notching Machine? Types, Features & Operation 1

The main structure is made of steel plate, which is solid and durable.

Only the tools provided by the standard machine can meet the processing needs of general sheet metal processing plants.

It is not necessary to make a set of molds to process a workpiece with an angle or a certain thickness like a common punch press.

Compared with punch press, angle notching machine has the following advantages:

1. Reduce the use cost;

2. Reduces the trouble of frequent die change and clamping of ordinary punch;

3. Improve work efficiency;

4. Reduce the labor intensity of workers;

5. Reduce the risk factor of workers;

6. At the same time, low noise processing creates a quiet working environment for the factory and workers.

The angle notching machine is suitable for shearing metal plate materials.

It is widely used in many fields such as automobile manufacturing plants, ship berths, elevators, electrical equipment, pipes, cookware and stainless steel products.

Types of notching machine

Notching machine can be divided into three types, namely: pedal notching machine, pneumatic notching machine and hydraulic notching machine.

According to the angle of the blades at both ends, the notching machine can be divided into adjustable angle notching machine and fixed angle notching machine.

Adjustable angle hydraulic notching machine have a wide range of cutting angles and high cutting accuracy.

The cutting angle is generally 40-135 degrees.

Any adjustment within this range can achieve a relatively ideal cutting state;

It can be adjusted and processed according to symmetry or asymmetry to adapt to various thicknesses and materials.

The cut edge of the plate is smooth.

The fixed angle hydraulic notching machine has a shearing angle of 90 degrees, high cutting speed, compact structure, small volume and convenient operation.

Pedal notching machine:

As the name implies, the pedal mode is used to work, which not only saves labor, but also greatly improves the efficiency of work.

At the same time, the scissors of the pedal nothing machines are made of silicon, and the blades are not easily damaged and do not collapse.

Pneumatic notching machine:

It mainly adopts pneumatic transmission and is used to shear square metal boxes and metal disc box corners.

The main feature is that the weight is relatively light, the style is good-looking and novel, and the quality of shearing is not worried.

Hydraulic notching machine:

It mainly adopts hydraulic transmission and is a new special cutting machine, which can quickly and accurately cut triangular notches on the edges and corners of metal plates.

It not only has sufficient strength but also has certain toughness, so it is suitable for various needs of various hardware processing industries, and it is also the most common type of notching machines in the current market.

Double station hydraulic notching machine

The double station hydraulic notching machine is an addition to the original angle cutting machine.

With the special die, the functions of punching, grooving, bending and corner cutting can be realized.

So that its application range is wider.

Features of notching machine

Notching machine mainly include fixed angle notching machine and adjustable angle notching machine.

The performance characteristics are as follows:

1) The structure is compact, the mechanical structure ensures the rigidity of the machine tool, and the solid guide ensures the cutting accuracy and blade life.

2) Foot switch control for easy operation;

Jog or cycle mode can be selected for operation.

3) The angle scale indicates that it is very convenient to adjust the angle with the hand wheel.

4) The stroke can be adjusted to improve the shearing speed.

5) Equipped with shear length ruler, the position of positioning stopper can be adjusted and the shear length can be set.

6) The surface of the worktable is ground to be smooth and flat without damaging the workpiece.

7) The cutter is suitable for cutting carbon steel and stainless steel.

8) It is equipped with presser foot to eliminate the distortion and deformation of the sheet during shearing.

9) The plastic protective cover can avoid contacting the shearing part and ensure the safety of operators and equipment.

10) Automatic lubrication of guide post reduces maintenance requirements.

1. The blade clearance is automatically adjusted according to the thickness of the shear plate.

2. Adopt hydraulic transmission mode.

3. The fixed shear angle is 90 °.

4. Adjustable angle scale device.

5. The whole machine is used for the overall welding structure of steel plate.

6. Centralized lubrication system.

Operating procedures for angle notching machine

1. Basic operation steps

1.1 Startup:

① Turn the main power switch to “on”;

② Turn clockwise to open the emergency stop button;

③ Press the oil pump start button;

④ Selector switch (inching and single time);

⑤ Adjust the ruler according to the shear angle size, lock and put the workpiece;

⑥ Press the foot shear switch to cut;

1.2 Commissioning:

Before angle cutting, it is necessary to conduct a test run.

Select the selection switch for a single time, and step on the foot shear switch to see whether the up and down movements of the white steel knife are normal, otherwise the knife and the machine will be damaged.

Then operate continuously for 1-2 times, and confirm that there is no abnormal sound before working.

1.3 Gear confirmation and adjustment:

Before angle cutting, check whether the gear is adjusted to the specified position.

1.4 Angle cutting

1.4.1 Remove the burrs on the edge of the plate before corner cutting;

1.4.2 The angle cutting shall be close to the gear surface;

1.4.3 After the corner cutting is completed, the residual materials will fall into the residual material box behind the machine body (it must be cleaned regularly)

1.5 Shutdown

Step on the foot switch → press the emergency stop button → turn the main power supply to the “off” state.

2. Safety operation procedures

2.1 Strictly observe the safety operation regulations and wear labor protection articles as required;
