Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a steel structure cutting device. Background Art

[0002] Steel structure refers to a building structure that uses steel as the main component material. It is usually composed of steel columns, steel beams, steel frames and other components. It has the advantages of light weight, high strength and good durability. It is widely used in industrial plants, commercial buildings, bridges, tower cranes and other fields. At present, when using steel structures, they often need to be cut according to the actual situation at the time of use. When cutting, a cutting machine is generally used to cut the steel structure.

[0003] As in the prior art, the patent with patent authorization announcement number CN214721070U discloses a cutting device for steel structure, including a base, an upper outer surface of the base is movably connected with a motor, a front outer surface of the motor is fixedly connected with a pressing rod, a sliding groove is provided on one side outer surface of the pressing rod, a sliding block is slidably connected inside the sliding groove, a lead block is fixedly connected to the outer surface of the slider on the side away from the sliding groove, a threaded groove is provided on the outer surface of one side of the lead block, a threaded rod is threadedly connected inside the threaded groove, a cutting blade is fixedly connected to the outer surface of one side of the motor, a protective shell is fixedly connected to the corresponding positions of the motor and the cutting blade, a receiving groove is provided on the outer surface of the upper end of the base, sliding grooves are provided on both sides of the inner surface of the receiving groove, a sliding block is movably connected inside the sliding groove, and a storage block is fixedly connected to the outer surface of the sliding block on the side away from the sliding groove, so that cutting no longer requires manual pressing through the lever principle, and the storage block is used to collect iron filings.

[0004] Although the cutting machine in the above patent can use the lever principle to make cutting no longer require manual pressure and use the storage block to collect iron filings, the existing cutting machine can only fix the steel structure material in one state (i.e., a state perpendicular to the cutting blade) with its own clamp during cutting. Therefore, if you want to cut a bevel on the steel structure, you can only manually fix the steel structure material for cutting by workers. This fixing method is not only prone to errors, but also unsafe. Therefore, the existing cutting machine has certain defects. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figure 1-4 A steel structure cutting device comprises a base plate 1 and a cutting machine body 2 connected to the base plate 1, a rotating shaft 3 is rotatably connected to the base plate 1, a fixed clamping block 4 is fixedly connected to the top of the rotating shaft 3, a threaded block 5 is fixedly connected to one side of the fixed clamping block 4, a positioning block 6 is fixedly connected to the bottom of the threaded block 5, a positioning groove 8 matching the positioning block 6 is opened on the base plate 1, a threaded rod 9 is threadedly connected to the middle position of the threaded block 5, and a movable clamping block 10 is rotatably connected to one end of the threaded rod 9 close to the fixed clamping block 4.

[0021] The steel structure cutting device in the utility model can push the threaded rod 9 when it is necessary to cut a bevel at the end of the steel structure material, and the threaded rod 9 can drive the fixed clamp block 4 and the movable clamp block 10 to rotate with the rotating shaft 3 as the axis until the fixed clamp block 4 and the movable clamp block 10 rotate to a suitable angle and then stop, and then the steel structure material is placed between the fixed clamp block 4 and the movable clamp block 10, and the threaded rod 9 is rotated to push the movable clamp block 10 to move in the direction of the fixed clamp block 4, and the steel structure material is clamped and fixed by the fixed clamp block 4 and the movable clamp block 10, so that a certain angle can be formed between the fixed steel structure material and the cutting blade of the cutting machine body 2, thereby cutting a bevel, and the operation is simple and convenient. In addition, the structure of the cutting machine body 2 in the utility model is similar to the structure of a steel structure cutting device disclosed in the patent authorization announcement number CN214721070U, so it will not be elaborated on here.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, the end of the threaded rod 9 away from the fixed clamp block 4 is slidably connected with an indicator block 12. The indicator block 12 indicates the angle of the threaded rod 9, so that the worker can judge the angle between the steel structure material and the cutting blade on the cutting machine body 2.

[0023] like Figures 1 to 4As shown, an arc-shaped slide groove 14 is provided on the top of the base plate 1, and the width of the slide groove 14 matches the length of the indicator card block 12. A card slot 15 is provided on one side of the slide groove 14, and the card slots 15 are equidistantly distributed, and the width of the card slot 15 matches the width of the indicator card block 12.

[0024] Specifically, the angle between each slot 15 is 5°, so the angle between the threaded rod 9 and the cutting blade can be determined based on the slot 15 where the indicator block 12 is located. Since the inclination angle of the bevel that needs to be cut out of the steel structure material is a multiple of 5 or 10, the angle of 5° between adjacent slots 15 does not affect its normal use.

[0025] like Figure 2 and Figure 4 As shown, an elastic member 13 is provided between the indicating block 12 and the threaded block 5 , one end of the elastic member 13 is fixedly connected to the threaded block 5 , and the other end of the elastic member 13 is fixedly connected to the indicating block 12 .

[0026] Specifically, before the threaded rod 9 rotates, the indicating card block 12 is pushed away from the threaded block 5 so that the indicating card block 12 is disengaged from the card slot 15. After the threaded rod 9 rotates to a suitable angle, the indicating card block 12 is released. Under the action of the elastic member 13, the indicating card block 12 moves toward the threaded block 5 and is stuck in the card slot 15, preventing the threaded rod 9 from continuing to rotate around the rotating shaft 3.

[0027] like Figure 4 As shown, an anti-slip plate 7 is fixedly connected to the bottom of the positioning block 6. The anti-slip plate 7 has a limiting effect to prevent the positioning block 6 from escaping from the positioning groove 8.

[0028] like Figure 1 and Figure 4 As shown, a hand wheel 11 is fixedly connected to one end of the threaded rod 9 away from the movable clamping block 10, and an anti-skid pattern is provided on the surface of the hand wheel 11. Rotating the threaded rod 9 by the hand wheel 11 is more labor-saving and convenient.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
