The blade of the shearing machine is an important part of the entire shearing machine. Its material and processing directly determine the service life and shearing effect of the blade. The shearing blade is an essential tool for shearing metal sheets. Especially when shearing stainless steel products, the shearing blade must be sharp, wear-resistant, and tough. Therefore, the quality of the shearing machine blade is the key to determining the shearing effect.

(1) What are flat mouth and oblique mouth?

The blades of shearing machine accessories in industrial production are also called cutting knives. There are generally two types of blades that are most commonly used. One is 90°, commonly known as flat mouth; the other is 82°, commonly known as oblique mouth. So, what are the differences between the different designs of these two blades? What are the differences in their performance?

(2) What is the difference between flat mouth and oblique mouth?

The difference between these two types lies in the oblique shearing blade. The cut edge of the plate should be neater and more beautiful than the flat shearing blade at 90°. It is often used to cut thin plates on hydraulic swing shearing machines. However, due to the small force-bearing area of the oblique shear blade, it is particularly prone to chipping when used to cut thick plates. If the customer has a high demand for the cut sheets, it is necessary to choose a bevel shear blade with a particularly good material, so that the customer's needs can be met and the blade will not chip due to the thickness of the sheet.

How to distinguish whether the blade of a shearing machine is beveled or flat? You can use a 90° ruler to measure the blade. If they are parallel, it means it is a flat shearing blade; if there are gaps and angles, it means it is an oblique shearing blade. It should be noted here that the lower edge of the hydraulic shearing machine blade is currently flat on all sides at 90°.
