Technical Field

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

[0002] Steel is a crucial metal alloy composed of iron, a small amount of carbon and other elements. It has the characteristic of high strength and can bear great pressure and tensile force, which makes it an ideal material for building large building structures such as high-rise buildings and bridges, as well as manufacturing various mechanical equipment. Steel has excellent workability and can be processed by a variety of technological means. For example, casting can create complex shapes, forging can improve its strength and performance, welding can connect different parts together, and cutting can give it specific dimensions and shapes, which enables steel to be processed into various products from fine parts to huge structures.

[0003] In the existing cutting machine for steel processing, when cutting steel, one hand needs to hold and stabilize the steel, and the other hand swings the cutting machine to cut. However, the way of holding and fixing the steel by hand has insufficient stability, which affects the cutting accuracy. Moreover, only one piece of steel can be held manually, resulting in low cutting efficiency. In addition, a large amount of metal chips will be generated during the steel cutting process. The current cutting machine cannot automatically clean the chips and requires manual cleaning, which is time-consuming and laborious and reduces the efficiency of steel processing. Content of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figure 1 and Figure 2, An embodiment provided by the present utility model: A positioning and cutting device for steel profiles, including a bearing plate 1. On both the front and rear sides of the bearing plate 1, there are movable grooves 2. Inside the movable grooves 2, there is a bidirectional screw 5 rotatably connected. On the right end of the bidirectional screw 5, there is a first driven bevel gear 3 fixedly connected. On both the left and right sides of the bidirectional screw 5, there are movable blocks 4 threadedly connected. On the top of the movable blocks 4, there are clamping plates 6 fixedly connected. On the opposite ends of the clamping plates 6, there are bearing platforms 12 fixedly connected. Inside the bearing platforms 12, there are multiple conveyor wheels 13 arranged. In the middle of the right side inside the bearing plate 1, there is a double-shaft motor 20 fixedly connected. On the driving shafts of the double-shaft motor 20, there are transmission rods 21 fixedly connected. On the opposite ends of the transmission rods 21, there are first driving bevel gears 22 fixedly connected. The outer walls of the first driving bevel gears 22 are all meshed with the outer walls of the first driven bevel gears 3.

[0026] Specifically, start the double-shaft motor 20 to drive the transmission rod 21 to rotate. The transmission rod 21 drives the first driving bevel gear 22 to rotate. The first driving bevel gear 22 cooperates with the first driven bevel gear 3 to drive the bidirectional screw 5 to rotate. The rotation of the bidirectional screw 5 drives the movable blocks 4 to move towards the middle. The movable blocks 4 drive the clamping plates 6 at their upper ends to move towards the middle to clamp and fix the steel plate.

[0027] Refer to Figure 3 and Figure 4 , On the top ends of the clamping plates 6, there are fixing blocks 7 fixedly connected. In the middle of the upper side of the fixing blocks 7, there is a bolt 9 threadedly connected. On the top end of the bolt 9, there is a rotating handle 8 fixedly connected. On the bottom end of the bolt 9, there is a frustum 10 rotatably connected. On the bottom end of the frustum 10, there is a sphere 11 movably connected.

[0028] Specifically, rotate the rotating handle 8 to drive the bolt 9 to rotate and descend. The bolt 9 drives the frustum 10 and the sphere 11 to move downward to fix the upper side of the steel plate, preventing the steel from moving up and down. The function of the sphere 11 is to facilitate the front and back movement of the steel plate driven by the conveyor wheels 13 when clamping the steel plate up and down.

[0029] Refer to Figure 3 , Below the clamping plates 6, there is a cleaning roller 14. The cleaning roller 14 is rotatably connected to the inside of the movable block 4. On the right end of the cleaning roller 14, there is a second driven bevel gear 15 fixedly connected. Inside the movable block 4, there is a rotating shaft 16 rotatably connected. On the bottom end of the rotating shaft 16, there is a circular gear 18 fixedly connected. On the upper side of the front end of the bearing plate 1, there are racks 19 arranged. The outer wall of the circular gear 18 is meshed with the outer wall of the rack 19. On the top end of the rotating shaft 16, there is a second driving bevel gear 17 fixedly connected. The outer wall of the second driving bevel gear 17 is meshed with the outer wall of the second driven bevel gear 15.

[0030] Specifically, during the movement of the movable block 4, the internal circular gear 18 contacts the rack 19 and rotates. The circular gear 18 drives the rotary shaft 16 to rotate, and the rotary shaft 16 drives the second driving bevel gear 17 to rotate. The second driving bevel gear 17 cooperates with the second driven bevel gear 15 to drive the cleaning roller 14 to rotate. The cleaning roller 14 sweeps the debris falling on the upper end of the bearing plate 1 into the dust inlet 23 to clean the upper surface of the bearing plate 1.

[0031] Refer to Figure 1 and Figure 5 At the top end of the bearing plate 1, a U-shaped frame 27 is fixedly connected. In the middle of the top of the U-shaped frame 27, an electric telescopic rod 28 is fixedly connected. At the bottom end of the electric telescopic rod 28, a cutting mechanism 29 is fixedly connected. A plurality of dust inlets 23 are arranged inside the bearing plate 1. At the bottom end of the bearing plate 1, a base 24 is fixedly connected. On the upper side of the inner wall of the base 24, an aggregate table 25 is fixedly connected. At the bottom end of the aggregate table 25, a waste collection box 26 is arranged.

[0032] Specifically, start the electric telescopic rod 28 to drive the cutting mechanism 29 to lift and lower, so as to adjust the height of the cutting mechanism 29 up and down according to the thickness of the steel. The aggregate table 25 converges the debris falling from the dust inlet 23, and the waste collection box 26 arranged at the bottom end of the aggregate table 25 is used for collection.

[0033] Working principle: When in use, place the steel plate on the bearing table 12, start the double-shaft motor 20, the double-shaft motor 20 drives the transmission rod 21 and the first driving bevel gear 22 to rotate. The first driving bevel gear 22 drives the first driven bevel gear 3 and the bidirectional screw 5 to rotate. The bidirectional screw 5 drives the movable block 4 and the clamping plate 6 to move towards the middle to clamp and fix the steel. Rotate the rotary handle 8 to drive the bolt 9 to rotate. The bolt 9 drives the round table 10 and the sphere 11 to descend and contact the top of the steel. The steel moves forward under the drive of the conveyor wheel 13. Start the electric telescopic rod 28 to drive the cutting mechanism 29 to descend to cut the steel. After cutting, start the double-shaft motor 20 to drive the movable block 4 to move left and right. While the movable block 4 is moving, the circular gear 18 cooperates with the rack 19 to drive the rotary shaft 16 and the second driving bevel gear 17 to rotate. The second driving bevel gear 17 cooperates with the second driven bevel gear 15 to drive the cleaning roller 14 to rotate to sweep the debris falling on the upper end of the bearing plate 1. The debris enters the inside of the aggregate table 25 through the dust inlet 23 and finally enters the waste collection box 26 to complete the collection of the debris.
