At the same time, the push block is used to fix the sheet metal desk legs, and the telescopic spring is used to press the sheet metal desk legs downward, so as to push away the cut sheet metal desk legs to achieve separation, avoid one side from tilting during cutting, and thus improve cutting efficiency and stability.

[0044] 2. The cutting device for processing sheet metal office desk legs is provided with a heat dissipation mechanism. When cutting downward, the push block is forced to squeeze the telescopic spring to move upward, and the expansion and contraction of the telescopic spring is shortened, thereby increasing the pressure on the sheet metal office desk legs to improve the fixing effect. At this time, during the movement of the push block, the spray pipe is synchronously driven to deflect through the action of the connecting rod, the double-ball connecting rod, and the pull ring, thereby achieving a cooling effect when cutting with a reciprocating saw, avoiding local overheating, affecting the life of the reciprocating saw, and reducing the rigidity of the sheet metal office desk legs.

[0045] 3. The cutting device for processing sheet metal office desk legs, through the heat dissipation mechanism, uses the cleaning sleeve to move up and down, and then moves relative to the reciprocating saw. The cleaning sleeve slides on the outer wall of the reciprocating saw, thereby cleaning the outer wall of the reciprocating saw to prevent dust from adhering to the outer wall and thus affecting its life.

[0046] 4. The cutting device for processing sheet metal desk legs uses a movable mechanism to fix the sheet metal desk legs horizontally using a clamp block, and simultaneously uses a second clamp plate to fix the sheet metal desk legs longitudinally, thereby improving stability during cutting.

[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] See also Figure 1-10 One embodiment of the present invention is: a cutting device for processing sheet metal desk legs, comprising a processing table 1, and also comprising:

[0060] Two slide rails 2 are fixedly connected to the front and rear sides of the top of the processing table 1;

[0061] The moving mechanism 3 is arranged on the slide rail 2 and is used to fix the sheet metal desk legs;

[0062] A cutting mechanism 4, arranged on the slide rail 2, for cutting the sheet metal desk legs;

[0063] The heat dissipation mechanism 5 is arranged on the cutting mechanism 4 and is used to dissipate heat from the sheet metal desk legs during cutting;

[0064] Wherein, the cutting mechanism 4 comprises:

[0065] A door frame 41 is fixedly connected to the two slide rails 2;

[0066] The motor 42 is mounted on one side of the door frame 41;

[0067] A reciprocating saw 43, mounted at the output end of the motor 42, is used to cut sheet metal desk legs;

[0068] A plurality of mounting blocks 45 are movably connected to both sides of the outer wall of the door frame 41, and the motor 42 is mounted on the mounting blocks 45;

[0069] A top fixing block 46 is fixedly connected to two adjacent mounting blocks 45 and is used to push the mounting blocks 45 to move on the portal frame 41;

[0070] Two telescopic push rods 44 are respectively fixedly connected to the top of the door frame 41, and the output ends thereof are connected to the top of the top fixed block 46.

[0071] The cutting mechanism 4 also includes:

[0072] A connecting plate 47, fixedly connected between the two mounting blocks 45;

[0073] The push block 48 is connected to the lower side of the connecting plate 47 through two telescopic springs 49 to resist the sheet metal desk legs.

[0074] Working principle: When cutting the sheet metal desk legs, first fix the sheet metal desk legs through the moving mechanism 3, and then move them to the cutting mechanism 4 for cutting. At this time, start the motor 42, and then drive the reciprocating saw 43 to work, so as to cut the sheet metal desk legs. When the sheet metal desk legs move to the cutting position, start the telescopic push rod 44, and then push the top fixed blocks 46 on both sides to move downward synchronously through its output end. At this time, the installation block 45 will be pushed and the motor 42 and the reciprocating saw 43 will be driven downward to cut the sheet metal desk legs, so as to achieve a uniform length of the sheet metal desk legs.

[0075] At the same time, when the reciprocating saw 43 moves downward, the push block 48 will contact one end of the sheet metal desk leg to fix it, so as to improve its stability during cutting. At the same time, when moving downward and cutting, the sheet metal desk leg is squeezed downward by the telescopic spring 49 to push away the cut sheet metal desk leg to achieve separation and improve cutting efficiency and stability.

[0076] See also Figure 1-10 Based on the above embodiment, in another embodiment of the present invention, the heat dissipation mechanism 5 includes:

[0077] The box 51 is fixedly connected above the connecting plate 47 and is used to store cutting fluid;

[0078] A spray pipe 52 is fixedly connected to the outer wall of the box body 51 and connected to the spray pipe 52 through a water pump for spraying;

[0079] A pull ring 53 is fixedly connected to the outer wall of the spray pipe 52;

[0080] One end of the connecting rod 55 is connected to the outer wall of the push block 48 , and the other end is connected to the pull ring 53 through a double-ball connecting rod 54 .

[0084] The L-shaped connecting rod 56 is fixedly connected between the connecting rod 55 and the cleaning sleeve 57 , and is used to push the cleaning sleeve 57 to move and clean the reciprocating saw 43 .

[0085] The two ends of the double-ball connecting rod 54 are rotatably connected to the pull ring 53 and the connecting rod 55 respectively, and are clamped and rotated through the spherical grooves provided on the pull ring 53 and the connecting rod 55.

[0086] An inclined groove is provided on the top of the processing table 1 for collecting cutting fluid and the cut sheet metal desk leg scraps.

[0087] Working principle: When cutting, the push block 48 will contact the sheet metal desk leg through downward extrusion and cutting, and produce resistance to squeeze the telescopic spring 49, which will push the push block 48 to move upward, thereby further improving the extrusion and fixation of the sheet metal desk leg. At the same time, during the upward movement of the push block 48, it will move upward through the connecting rod 55, thereby driving the double-ball connecting rod 54 to move upward, and driving the pull ring 53 to move upward, thereby realizing the deflection of the spray pipe 52 and changing the spray position, so as to improve the cooling effect of the reciprocating saw 43 during cutting, avoid local overheating, affect the life of the reciprocating saw 43 and reduce the rigidity of the sheet metal desk leg;

[0088] At the same time, during the cutting process, the cleaning sleeve 57 will be pushed upward by the L-shaped connecting rod 56 to facilitate the reciprocating saw 43 to disengage from the cleaning sleeve 57 and realize cutting of the sheet metal desk legs. At the same time, after the cutting is completed, the push block 48 will disengage from the support for the sheet metal desk legs. At this time, it will move downward under the push of the telescopic spring 49, and the L-shaped connecting rod 56 will be driven downward by the connecting rod 55, thereby pushing the cleaning sleeve 57 to move downward. The cleaning sleeve 57 slides on the outer wall of the reciprocating saw 43, thereby realizing the cleaning of the outer wall of the reciprocating saw 43 to prevent dust from adhering to the outer wall and thus affecting its life.

[0099] Working principle: By placing the sheet metal desk leg that needs to be cut on the slider 31, the two-way screw 34 is rotated to push the two clamping blocks 32 closer to each other, so as to clamp the sheet metal desk leg for fixation. At the same time, during the movement of the two clamping blocks 32, the top of the sheet metal desk leg will be clamped by the second clamping plate 38 to fix the sheet metal desk leg from above. At this time, the spring 37 is used to pull the second clamping plate 38 to slide downward on the round rod 36 to fix the sheet metal office leg from top to bottom, thereby improving its stability during cutting.
