technical field

The invention relates to the technical field of hardware accessories, in particular to an angle steel cutting device capable of accurately positioning the cutting length.

Background technique

Hardware usually refers to the five metal materials of gold, silver, copper, iron and tin. Products made of hardware materials are usually divided into two categories: large hardware and small hardware. Angle steel belongs to large hardware, and angle steel is commonly known as angle steel. Iron is a long strip of steel whose two sides are perpendicular to each other. The angle steel can be composed of various stress-bearing components according to the different needs of the structure. The angle steel can also be used as a connector between the components. Angle steel is often seen.

The angle steel is often in a long size when it leaves the factory. The user needs to use the machine to cut such long angle steel into smaller angle steel one by one before they can be used. The general angle steel cutting device is used for angle steel cutting work. , Since there is no proper fastening device, the user needs to hold the angle steel in one hand to stabilize it, and the other hand needs to operate the cutting machine synchronously. During this period, the angle steel is easily deformed, the cutting end face is not neat, which affects the use effect, and the cutting device cannot be accurate. To locate the cutting length, users need to use their own experience to cut the appropriate length.
