Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 and 2, an embodiment of the present invention is: the utility model provides a steel pipe internal welding muscle remove device, includes tool bit 1, and the front end of tool bit 1 is connected with traction lever 2, and the upper end of tool bit 1 is equipped with blade 3, and tool bit 1 has been seted up by

chip removal passageway

4, 3 intercommunication chip removal passageways 4 of blade, and 1 bottom of tool bit articulates has the cardboard 5 of trapezium structure, the one end on the long base of cardboard 5 with 1 bottom of tool bit is articulated, highly is less than of cardboard 5 the length of cardboard 5, the long base of cardboard is towards traction lever one side. When the clamping plate 5 is unfolded backwards, the overall height of the cutter head 1 and the clamping plate 5 is the inner diameter length of the steel pipe, and when the clamping plate 5 is folded forwards, the overall height of the cutter head 1 and the clamping plate 5 is reduced; after the clamping plate 5 is folded forwards, the traction rod 2 can extend into the steel pipe from one end of the steel pipe and enables the tool bit 1 to move out of the other end of the steel pipe, the clamping plate 5 is unfolded backwards, the tool bit 1 is corrected to enable the cutting edge 3 to be over against the inner welding rib of the steel pipe, the tool bit 1 is pulled back by the traction rod 2 to finish removal of the inner welding rib, the traction rod 2 only needs to be slightly longer than the length of the steel pipe, occupied area of equipment is greatly reduced, cost is saved, and working efficiency is higher.
