[0022] See also Figure 1-5 The utility model provides a steel pipe cutting device for construction with a fixing function, comprising a cutting table 1, a positioning table 2 is fixedly installed on the surface of the cutting table 1, and a steel pipe blank 12 is arranged on the surface of the positioning table 2, and a fixing structure 11 is installed on the outer side of the positioning table 2, and the steel pipe blank 12 on the positioning table 2 is limited and fixed by the fixing structure 11; a support seat 4 is inserted into the right end of the steel pipe blank 12, and the end of the support seat 4 is fixed to a connecting column 9, and a transmission column 91 is welded and fixed on the side wall of the connecting column 9, and the end of the transmission column 91 away from the connecting column 9 is fixed to a positioning pin 92;

[0023] The fixing structure 11 includes a fixing frame 115, and the bottom of the fixing frame 115 is screwed to the surface of the positioning platform 2. At the same time, a mounting stud 114 is screwed on the top wall of the fixing frame 115, and the bottom of the stud 114 is movably connected to the mounting frame 112. Two sets of pressure wheels 111 are movably installed on the lower side of the mounting frame 112. A positioning groove 3 matching the size of the steel pipe blank 12 is opened on the surface of the positioning platform 2, and a receiving hole 6 is opened on the right side of the positioning platform 2.

[0024] Working principle: When in use, first rotate the rotating wheel 116 to rotate the stud 114, so that the two sets of pressing wheels 111 respectively cover the two sides of the surface of the steel pipe blank 12 to press it. At this time, the high-speed rotating cutting blade 10 cuts the steel pipe blank 12. When cutting the steel pipe blank 12, hold the end of the steel pipe blank 12 and slowly rotate the steel pipe blank 12 to achieve ring cutting of the steel pipe blank 12.

[0025] As a preferred embodiment, two groups of pressing wheels 111 are arranged in parallel, and the two groups of pressing wheels 111 respectively cover both sides of the surface of the steel tube blank 12 to press it.

[0026] like Figure 1-4 As shown: two sets of pressing wheels 111 respectively cover both sides of the surface of the steel tube blank 12 to press it, and the two sets of pressing wheels 111 are set to roll, so that they can rotate slowly when the steel tube blank 12 is cut.

[0027] As a preferred implementation, the top of the stud 114 is fixedly connected to the rotating wheel 116 , and guide rods 113 are installed on both sides of the stud 114 , and the guide rods 113 are inserted into the guide holes opened on the fixing frame 115 .

[0028] A side opening 5 is provided on the outer side of the support seat 4 , and the side opening 5 is arranged in a ring shape along the outer circumferential position of the support seat 4 , and the side opening 5 , the cutting blade 10 and the positioning needle 92 are arranged opposite to each other.

[0029] When the mounting frame 112 is lifted or lowered, the four guide rods 113 thereon are inserted into the guide holes provided on the fixing frame 115, so as to limit and guide the mounting frame 112 during the lifting or lowering process, thereby preventing the mounting frame 112 from tilting during the lifting or lowering process;

[0030] When the mounting frame 112 is operated to be lowered, it is prevented that the two sets of pressing wheels 111 press down the steel tube blank 12 too tightly to prevent the steel tube blank 12 from being unable to rotate.

[0031] As a preferred embodiment, the end of the connecting column 9 passes through the through hole on the fixing seat 7 and is locked by two sets of nuts 8, and the bottom of the fixing seat 7 is fixedly connected to the cutting table 1.

[0033] The support seat 4 is inserted into the cut part inside the steel tube blank 12. At this time, when the cut part of the steel tube blank 12 is subjected to force, the cut surfaces on both sides of the cutting point are limitedly supported by the cylindrical support seat 4 to prevent the side wall at the cut surface from being sunken. At the same time, the setting of the side opening 5 can prevent the cutting blade 10 from impacting the support seat 4 and causing damage to the support seat 4. The side opening 5 is arranged opposite to the positioning pin 92. The position of the positioning pin 92 can be used to locate the position of the side opening 5 inside the steel tube blank 12.

[0034] The position of the support seat 4 inside the steel tube blank 12 can be adjusted by the fixing seat 7 and the nut 8 to change the cutting position of the steel tube blank 12 .

[0035] The cutting blade 10 is a saw blade on a J3GA-400 profile cutting machine.
