Multi-blade rotary feeding pipe cutting cutterhead and pipe cutter

Abstract

The invention relates to the technical field of cutting tools, in particular to a multi-blade rotary feeding pipe cutting cutterhead and a pipe cutter. The multi-blade rotary feeding pipe cutting cutterhead comprises a shell, a cutterhead body, a cutterhead driving device used for driving the cutterhead body to rotate in the shell, a plurality of cutter rests and blades arranged on the cutterhead body, and a blade feeding mechanism used for driving the blades to rotate along with the cutterhead body in the forward direction to conduct synchronous stepping feeding. The cutterhead has the advantages that the multiple blades are arranged, the multiple blades can be driven to be synchronously fed in an electric driving mode, the blade feeding process and the cutterhead rotating process are synchronously carried out, and each blade can synchronously carry out tiny stepping type feeding every time the cutterhead rotates by a circle. The pipe cutter comprises the multi-blade rotary feeding pipe cutting cutterhead and a clamping device which are coaxially and fixedly connected together. The pipe cutter has the advantage that it can be guaranteed that pipes cannot accidentally slide relative to the cutterhead in the pipe cutting process.

Description

technical field [0001] The invention relates to the technical field of cutting tools, in particular to a multi-blade rotary feed pipe cutting cutter head and a pipe cutter. Background technique [0002] The pipe cutter is mainly a cutting tool for stainless steel pipes, copper pipes, and plastic pipes. It generally includes a cutter head and a cutting blade arranged on the cutter head. When working, it is necessary to continuously move the cutting blade toward the axis of the cutter head (ie Blade feed), and the cutter head drives the blade to rotate around the pipe to achieve cutting of the pipe. Existing pipe cutters are generally driven by hand, so that the pipe cutter rotates around the pipe to achieve cutting. This kind of pipe cutter cannot be used in some relatively narrow occasions, and the work efficiency is low. Operators use it for a long time. It is easy to cause damage to the wrist. In addition, although there are some electric pipe cutters at present, there a...

AI Technical Summary

Problems solved by technology

Existing pipe cutters are generally driven by hand, so that the pipe cutter rotates around the pipe to achieve cutting. This kind of pipe cutter cannot be used in some relatively narrow occasions, and the work efficiency is low. Operators use it for a long time. Easy to cause damage to the wrist

In addition, although there are some electric pipe cutters at present, there are usually the following problems: ①There is only one blade, and if multiple blades are used, it is difficult to feed multiple blades synchronously; ②It is difficult to synchronize the blade feeding process and the cutterhead rotation process ; ③ It is difficult to make the cutting blade perform uniform and small step-by-step feeding with the rotation of the cutter head; the above problems will also lead to problems such as low cutting efficiency and poor quality of pipe cutting

In addition, the existing pipe cutters generally have the problem that the position of the pipe is difficult to fix during the pipe cutting process, which leads to misalignment of the cutting position due to the accidental sliding of the pipe relative to the cutter head during pipe cutting, which affects the quality of pipe cutting
