Rotary centrifugal multi-blade cutting machine

Abstract

The invention relates to the field of pipe material feeding, in particular to a rotary centrifugal multi-blade cutting machine. The machine comprises a machine base and a cutting unit; the machine base comprises a motor, a control panel, a driving gear, an auxiliary gear, a supporting gear and a supporting bearing; the cutting unit comprises a gear cutter head, a knife seat mechanism, a centrifugal mechanism and a connecting rod, various sliding grooves are formed in the surface of the gear cutter head for respectively mounting the knife seat mechanism and the centrifugal mechanism, the knifeseat mechanism includes a base, a cutter head sliding block, a blade, a return spring, a limit block and the like, the cutter head sliding block is connected to the base through a sliding through, a circular groove formed in the middle after connection is used for mounting the spring, and the connecting rod is connected to the cutter head sliding block and the centrifugal mechanism. The structureof the machine is simple, only a single motor is required to drive the cutter head to rotate, the centrifugal force of the centrifugal mechanism is converted into the axial cutting force of the bladeduring the rotary cutting process, no other power is provided, the blade replacement is convenient, the contact area of the annular blade and a pipe material is large, and the quality of the incisionis ensured.

Description

technical field [0001] The invention relates to a pipe material cutting tool, in particular to a rotary centrifugal multi-blade cutting machine. Background technique [0002] At present, most of the pipe cutting operations at home and abroad are completed by using grinding wheels or saw blades. Although the cutting speed of the grinding wheel saw is fast, the cutting accuracy is low. During the process of cutting metal pipes, a large number of sparks will be generated, and burrs or flashes are likely to be generated at the incision of the pipe. If the pipe with a larger diameter is cut, the pipe may be broken. The grinding wheel saw machine usually uses a motor to drive the saw blade to rotate, and the tangential force is provided by manpower. It is difficult to provide a suitable tangential force during the cutting process. Excessive tangential force will affect the shape of the pipe. If the tangential force is too high If it is small, it will take a long time to cut and a...

Problems solved by technology

However, the action of the entire cutting process is completed by two mechanisms, so the structure of the transmission system is complicated, resulting in high cost of machine equipment, high precision of parts manufacturing, and difficult operation. At the same time, the cutter is installed on the cutter holder, and it is difficult to replace the blade after it is damaged.
