Description

Technical Field

[0001] The utility model relates to the field of cutting machines, in particular to a multi-blade cutting machine. Background Art

[0002] With the rapid development of modern industrial production, the demand for cutting and processing of metal materials is increasing day by day. Especially in the construction, machinery manufacturing, metallurgy and mining industries, the cutting of metal materials such as steel bars and steel plates has become an indispensable production link.

[0003] However, in the cutting operation, the wear and replacement of the cutter is a common problem. The current cutting machines usually adopt a single cutter design. Once the cutter becomes blunt or damaged, it needs to be replaced frequently, which not only increases the production cost, but also affects the production efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the utility model provides a multi-blade head cutting machine.

[0005] The technical solution adopted by this utility model:

The outer wall of the turntable is provided with six sliding holes, and the six sliding holes are respectively located on the outsides of the six sliding grooves and penetrate the sliding grooves. A connecting plate is provided on the inner side of the sliding hole. The connecting plate is in the shape of an angle iron. The connecting plate slides with the sliding hole. A bolt is inserted at the top of the connecting plate. The bolt penetrates the connecting plate and is threadedly connected to the rear end of the outer wall of the cutter. The top of the support frame is fixedly connected to a fixing frame, and the top of the front fixing frame is fixedly connected to a square tube. A notch is provided on the rear side of the square tube, and the notch is opposite to the top sliding groove. The top of the rear fixing frame is fixedly connected to a fixing column, and the top of the fixing column is fixedly connected to the outer wall of the cylinder body, and the output shaft of the cylinder faces forward and is opposite to the top connecting plate.

[0007] Beneficial effects of the utility model:

[0008] The utility model adopts cylinder drive and servo motor control, so that the whole cutting process is automated. The rapid extension and retraction of the cylinder can quickly complete the cutting action of the steel bar, and the servo motor can accurately control the rotation angle of the turntable, so that different cutters can be accurately turned to the working position. By arranging multiple slide grooves and cutters on the turntable, when one cutter becomes blunt or damaged, it can be quickly switched to another cutter, avoiding the trouble of frequent replacement of cutters.
