DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] As Figures 1 to 4 indicated, the utility model embodiment provides a section bar cutting machine, include: base 1, the upper surface one end of base 1 is provided with arm 5, one side of arm 5 is provided with grinding wheel 3, one side of arm 5 is provided with protection assembly 4, protection assembly 4 is located the outer surface of grinding wheel 3, and one end of base 1 is provided with spark baffle 2;Limiting mechanism 7, limiting mechanism 7 is arranged on the upper surface one end of base 1, and limiting mechanism 7 and arm 5 are correspondingly arranged to be used for fixing arm 5;

[0024] Specifically, as Figure 1 and Figure 2 indicated, when using, the section bar needing cutting is placed on base 1, and the position of grinding wheel 3 can be changed by rotating arm 5 at one end of base 1, so that grinding wheel 3 contacts the section bar to cut the section bar. In the cutting process, sparks are generally generated. In order to avoid the splashing of sparks, the protection assembly 4 and the spark baffle 2 are used to block and reduce the splashing range of sparks, thereby improving the practicability. The protection assembly 4 can protect grinding wheel 3, which can not only avoid the damage of grinding wheel 3 due to collision when not in use, but also prevent the damage of grinding wheel 3 to the human body.

[0025] In use, in order to avoid the situation that the machine arm 5 is overturned too much to cause the machine to fall down, when the machine arm 5 is erected by the elasticity of the reset spring 705, the machine arm 5 is limited by the limiting mechanism 7, so that it cannot rotate backward, but only can make downward cutting action forward. When not in use, the one end of the machine head of the machine arm 5 is in contact with the base 1, and the machine arm 5 is limited by the limiting mechanism 7, so that the function of the traditional profile cutting machine which can be realized by two parts is realized by the limiting mechanism 7, the structural complexity is reduced, and the use convenience is improved.

[0026] It should be noted that the spark arrester plate 2 is provided with double radii, and the sparks generated during cutting will roll along the radii of the spark arrester plate 2 and will not rebound, so that the effect of effectively avoiding spark rebound is achieved, and therefore the threat to the body injury of the operator is eliminated, and the use safety is improved.

[0027] Further, the limiting mechanism 7 comprises a sleeve 701 and a limiting boss, one end of the upper surface of the base 1 is provided with a mounting seat 11, one end of the machine arm 5 is rotatably installed in the mounting seat 11, the sleeve 701 is arranged on one side of the mounting seat 11, the sleeve 701 is internally provided with a limiting pin 702, the limiting pin 702 is connected with the limiting boss, and the limiting boss is arranged on one end of the machine arm 5; the limiting boss comprises a first limiting block 703, one end of the first limiting block 703 is provided with a second limiting block 704, and the first limiting block 703 and the second limiting block 704 are both provided with an arc surface on one side, and the arc surfaces are arranged in correspondence with the limiting pin 702;

[0028] Specifically, as shown in Figures 1 to 3 in use, the limiting pin 702 is pulled out, one end of the limiting pin 702 abuts against the arc surface on one side of the first limiting block 703 of the machine arm 5 when the machine head of the machine arm 5 is lifted to the highest position, so that the machine head of the machine arm 5 is positioned at the highest position, the limiting pin 702 is inserted when the machine head of the machine arm 5 needs to be pressed down for recovery, and one end of the limiting pin 702 abuts against the arc surface on one side of the second limiting block 704, so that the machine head is positioned at the lowest position, so that the opening and closing of the machine arm 5 are limited by the limiting pin 702, and the use convenience is improved.

[0029] Further, the other side of the machine arm 5 is provided with a driving motor 6, one end of the output shaft of the driving motor 6 is arranged on one side of the grinding wheel 3, a gap is formed on the connecting position between the machine arm 5 and the shell of the driving motor 6 to form an air outlet, and a plurality of guide vanes 10 are arranged at the gap and correspond to the driving motor 6;

[0030] Specifically, as shown in Figure 3As shown, the driving motor 6 is started to drive the grinding wheel 3 to work, and a plurality of guide vanes 10 are driven to rotate, so that the driving motor 6 can be assisted in heat dissipation, and the air outlet of the driving motor 6 can be guided to blow on the cutting part of the machine, so that dust on the cutting part is cleaned and does not accumulate, and the practicability is improved. It should be noted that the guide vane 10 has an arc, which can achieve the guiding effect. Compared with the traditional profile cutting machine, the air outlet of the motor heat dissipation structure is only a window for air outlet. The utility model can better perform cutting work.

[0031] Further, the protection assembly 4 comprises a fixed cover 401, one end of the fixed cover 401 is provided with a movable cover 404, one end of the upper surface of the fixed cover 401 is provided with a square nut 403, both ends of one side of the movable cover 404 are provided with positioning iron sheets 402, and the positioning iron sheets 402 are clamped with the square nut 403

[0032] The rotation and the up-down position limiting of the traditional profile cutting machine movable cover are completed by a rotating screw and a limiting screw.

[0033] Specifically, as shown in Figures 1 to 4 As shown, a square nut 403 is welded on the fixed cover 401, and two iron positioning iron sheets 402 are welded on the movable cover 404 to abut against the square nut 403 at the up-down positions, so that the up-down limiting effect is achieved.

[0034] In specific implementation, when the movable cover 404 is rotated to the position below the grinding wheel 3, the iron sheet welded on one side of the movable cover 404 hooks the square nut 403 on the fixed cover 401 to position the movable cover 404 at the lowermost position. Conversely, when the movable cover 404 is rotated to the upper surface of the fixed cover 401, the other positioning iron sheet 402 welded on the movable cover 404 abuts against the square nut 403 below the fixed cover 401 to position the movable cover at the uppermost position. The structure is simple and the operation is convenient.

[0035] Further, the upper surface of the machine arm 5 is provided with a plug wire sleeve 8, and the plug wire sleeve 8 is provided with a wrench 9.

[0036] Specifically, as shown in Figure 2 and Figure 3 As shown, the plug wire sleeve 8 can store the wrench 9, which can be taken out for use when the user replaces the saw blade, and is inserted into the plug wire sleeve 8 after use. The operation is convenient. Compared with the traditional profile cutting machine, the wrench 9 for disassembling the saw blade is not stored on the machine, but is an accessory separated from the machine, so that the plug wire sleeve 8 provided by the utility model can prevent the wrench 9 from being easily lost after use.

[0037] The above description of the embodiments is only used to help understand the method of the utility model and its core idea. It should be pointed out that for ordinary skilled persons in the art, without departing from the principles of the utility model, the utility model can be improved and modified in several ways, and these improvements and modifications also fall within the protection scope of the utility model claims.
