Description

Technical Field

[0001] The utility model relates to the technical field of water pipe processing devices, in particular to an electric hole expanding device. Background Art

[0002] During the production and processing of water pipes, reamer may be used. The main function of the reamer is to expand the diameter of existing holes or create new holes through its specific design, such as adjustable blades and tapered guide rods, to accommodate pipes of different specifications, ensuring that the connection between pipes is tight and stable to prevent leakage.

[0003] Existing production workshops generally use manual reamers, which usually consist of the following main parts: a handle, a rod and a reamer head; the working principle of the manual reamer is mainly based on cutting and extrusion forces. When the operator holds the handle and applies force, the force is transmitted through the rod, causing the reamer head to start rotating. During the rotation process, the blade or teeth of the reamer head cut along the hole wall toward the center, and at the same time, the extrusion force between the reamer head and the hole wall is used to extrude the material from the center of the hole wall to the outside, causing it to flow plastically, thereby expanding the diameter of the hole; since the staff needs to manually turn the knob handle, there are problems of high work intensity and low work efficiency.
