How to Adjust the Hydraulic Guillotine Shear Blade Gap

If the gap between the upper and lower blades is too large, it can damage the edge of the material that the shearing machine is cutting. Alternatively, it can also make the product wool roll over or have severe burring.

Therefore, it is important to properly adjust the hydrauilc guillotine shear blade gap before using. This will help to ensure that the blade is in good condition and will provide a smooth cut.

1. Loosen the left and right four bolts of the lower blade table.

The hydraulic guillotine shear blade gap is an important part of a shearing machine that helps maintain accuracy and quality during the cutting process. If the gap is too large, it can cause the material to roll over during the cutting operation.

This can result in burring and uneven cuts. The shearing gap can also be adjusted to fit different materials and thicknesses of material.

To adjust the gap, first loosen the left and right four bolts of the lower blade table. You may need a torque wrench to help you do this.

2. Manually turn the upper blade down to the proper position.

The gap between the upper and lower blades of a hydraulic swing beam shear blade is very important for obtaining good Shear quality. Therefore, it is necessary to adjust the gap of the shear blade regularly.

The gap should be 1 / 10-1 / 20 of the desired sheet metal thickness. This can be adjusted according to the needs of different sheets.

In addition, the rake angle should be adjusted periodically to avoid problems in the cut-off section of the material. These problems include bowing, where the material curves up higher than the center; cambering, where the material stays flat but the ends curve away from the shear blade; and twisting, where the material “corkscrews” so that opposite corners are higher than the center.

A high-efficiency Hydraulic guillotine shear machine is a valuable addition to any metal fabrication facility. It offers many benefits, including high efficiency and increased safety.

3. Use a feeler gauge to roughly adjust to 0.5 mm from the unoccupied part of the left hand and upper blade.

A feeler gauge is a linear measurement tool that can be used to accurately measure and mark gaps. It is commonly used to establish tappet clearances, spark plug gaps, and bearing clearances.

A typical feeler gauge set contains a series of graded metal leaves or blades calibrated to specific thicknesses. They are joined at one end with a pin or rivet and fold back like a fan into a handle.

They can be either steel, wire mesh or brass. All types have a weighting scale designed to suit their intended purpose.

There are also feeler gauge sets with bent blades, which can be useful when accessing smaller gaps is restricted or if space limitations are an issue. Some are even tapered, meaning the width of each blade narrows towards the tip.

4. Manually turn the blade up to the right position where the upper and lower blades are not disengaged.

The hydraulic guillotine shear blade gap is an important adjustment to ensure the best cutting quality and performance. If the gap between the upper and lower blades is too large or too small, damage to the material edge may occur during a cut.

This is especially true for thin sheet metals where too little gap can result in the blade being rolled over or having severe burring.

A guillotine shear blade has an adjustable gap that can be set to work with various types and thicknesses of sheet metal. Typically, the blade gap is adjusted to be between 0.05mm and 3mm for thin sheets, and progressively increases for thicker shear capacity.

5. Fine-tune until the feeler gauge can enter three wires and five wires can not enter.

A feeler gauge is a measuring and marking tool that can be used to check gaps between blades, shims, etc. They are typically available in a range of sizes and thicknesses, with some being colour coded for easier differentiation between specific shim thicknesses.

Some feeler gauges like fiber laser cutting machine are also angled - which can be useful for accessing harder to reach gaps. They are often labelled with the measurement units in either metric or imperial, but you should always make sure that you're buying a feeler gauge that will be suitable for your needs.

As with most tools, there is a technique to using a feeler gauge, and once you've got the hang of it it can become instinctive. If you're not confident using a feeler gauge, you may want to invest in a spark plug gap tool or a standard pair of pliers, which will allow you to manually measure and test the distance between the ground electrode and central electrode.
