Description

Technical Field

[0001] The invention belongs to the technical field of slotting construction, and in particular relates to a one-time forming construction method of a controllable slot size and a forming slotting machine. Background Art

[0002] Grooving is an important part of electromechanical installation engineering. It directly affects the subsequent secondary piping construction and the stability of the secondary structure. Currently, there are two main machines used for grooving: traditional grooving machines and one-shot grooving machines. Traditional grooving machines are the main grooving tools used in China. They use a single blade and can only cut a slit at a time. During construction, it is necessary to accurately mark the line twice, then use the grooving machine to cut twice, and then remove the middle part to complete this construction. During the construction process, there is a situation where the groove width is uneven, and the groove depth cannot be controlled.

[0003] The existing one-shot slotting machine has multiple blades and can slot once, but it cannot effectively control the slot width. After slotting once, some areas can be piped normally, but the required slot width cannot be reached. In order to save time and cost, some workers will not choose to widen the slot a second time, and the slot is difficult to widen a second time, resulting in the inability to complete the acceptance. Or some workers will deliberately widen the part with insufficient slot width when slotting, creating the illusion that the slot width is sufficient, which poses a safety hazard. In addition, the slot width opened by the existing one-shot slotting machine is generally narrow. Therefore, a one-shot slotting machine that can control the slot depth and slot width is particularly important. Summary of the invention
