Tapping equipment for inner wall of plastic pipeline

Abstract

The invention discloses plastic pipeline inner wall tapping equipment which comprises a mounting base, a plurality of mounting blocks are fixedly connected to the side wall of the mounting base, a plurality of mounting holes are formed in the mounting blocks, a pair of supporting rods is fixedly connected to the surface of the mounting base, a fixing straight plate is fixedly connected to the supporting rods, and a connecting base is mounted on the fixing straight plate; a limiting mechanism is fixedly mounted on the surface of the fixed straight plate, a tapping mechanism is fixedly mounted on the surface of the connecting seat, and a pair of supporting vertical rods is fixedly connected to the surface of the mounting base; compared with the prior art, when a plastic pipe is clamped between limiting plates, the inner wall of a threaded pipe can mutually extrude one end of a tapping shaft, a movable plate can be driven to move, an elastic strip can be driven to deform, a fixed spring can pull the limiting plates, and the clamping force on the surface of the plastic pipe can be increased; and the situation of thread slipping caused by deviation in the tapping process can be avoided, and the stability of the plastic pipe is improved.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a device for tapping the inner wall of a plastic pipe. Background technique [0002] In pipeline laying and other projects, it is often necessary to connect pipes. The plastic pipe and the plastic pipe are usually connected by a socket, while the connection between the metal and the plastic pipe needs to be threaded or frictionally connected by wrapping raw tape. The friction connection structure between the metal and the plastic pipe is not reliable enough, and the plastic pipe and the metal are prone to detachment, and for the threaded connection, it is necessary to first select a tapping knife with the same diameter as the metal threaded pipe, and then tap the plastic pipe. This method is not only complicated to operate, but also has low tapping efficiency, and the plastic thread is prone to slippage during the tapping process. For this reason, we propose a plastic ...

Problems solved by technology

[0002] In projects such as pipeline laying, it is often necessary to connect pipelines. The connection between plastic pipes and plastic pipes usually adopts a socket method, while the connection between metal and plastic pipes requires threaded connection or friction connection by wrapping raw tape. , the friction connection structure between the metal and the plastic pipe is not reliable enough, the plastic pipe and the metal are prone to detachment, and the threaded connection needs to first select a tapping knife with the same diameter as the metal threaded pipe, and then tap the plastic pipe. This method is not only complicated to operate, but also has low tapping efficiency, and the plastic thread is prone to slippage during the tapping process. Therefore, we propose a plastic pipe inner wall tapping equipment to solve the above problems
