Angle steel processing combined production line
The invention relates to the technical field of machining equipment, in particular to angle steel machining equipment, and particularly relates to an angle steel machining combined production line.
In the industries of electric power systems, bridges, telecommunications, geology, buildings and the like, mechanisms such as columns, brackets, frames and the like formed by processing angle steels are often used.
When the angle steel is used as an upright post, one end of the angle steel is usually subjected to sharpening processing and then used for convenience in use. Along with the development of the industry, the demand of angle steel needing to be cut to be sharp is increased year by year, because the traditional angle steel is generally cut and machined by a cutting machine, an operator needs to hold the angle steel on the cutting machine during cutting, after one side of the point of the angle steel needing to be cut is positioned, the cutting machine is used for cutting one side of the angle steel, then the other side of the point of the angle steel workpiece needing to be cut is turned by an angle and is repositioned, and then the cutting machine is used for cutting and machining the other side of the point of the angle steel needing to be cut. The cutting processing speed is low, the noise is high, and the cutting quality is greatly influenced by human factors of operators.
In order to improve the efficiency and quality of angle steel cutting, a new machining method has been proposed for angle steel cutting, and patent document No. CN206550196U discloses a cutting device named as a "cutting tool" which abandons the method of machining by a cutting machine and performs machining by a shearing method, thus greatly improving the quality and efficiency of angle steel cutting. However, according to the processing method provided in the patent document, in order to reduce the cost, the processing method is not favorable for the large-scale production of angle steel sharpening because the angle steel needs to be processed by the fixed placing device at one end and the workpiece needs to be unloaded from the end during processing, and the angle steel sharpening device which is more convenient to process and is favorable for industrial production is required at present.
When the angle steel is used as a bracket or a frame, the angle steel often needs to be subjected to angle folding processing, in order to fold the angle steel, a right-angle notch is processed on one side surface of the position, where the angle steel needs to be folded, of the angle steel, and then the angle steel is manually bent at the notch.
In the existing angle steel bevel processing equipment, a punch press can be used for punching right-angle notches on angle steel, but the subsequent bevel still needs manual bevel folding, so that the defects of low processing efficiency, unreliable quality and high labor intensity exist.
Because the existing angle steel processing equipment can provide punching and cutting processing operations, if the existing angle steel processing equipment can be further designed to be simultaneously suitable for processing angle steel punching, sharpening, cutting and bending angles, the efficiency of angle steel processing can be greatly improved, and the labor intensity of workers can be effectively reduced.
