DETAILED DESCRIPTION

[0026] See also Figure 1-Figure 3In an embodiment of the present invention, a steel structure cutting device includes a bracket 1, a shield 11 is provided at one end of the bracket 1, the shield 11 and the bracket 1 are welded, or can be integrally cast, the shield 11 is a semicircular cover-shaped cavity, and strip grooves are symmetrically embedded on both sides of the bracket 1. The bracket 1 is a strip-shaped rod material, which can be conveniently held through the strip grooves on the bracket 1. A handle bar 12 is fixedly connected to one side of the shield 11, and the handle bar 12 can also be conveniently held, so that manual operation can be convenient for cutting; a first rotating shaft is provided in the shield 11 for rotation connection Shaft 13, one end of the first rotating shaft 13 is drivingly connected to a motor installed on the shield 11, a blade 14 is assembled and connected to the periphery of the first rotating shaft 13, and the upper side of the blade 14 is located in the shield 11, a second rotating shaft 15 is penetrated at one end of the bracket 1 away from the shield 11, and first rotating sleeves 16 are rotatably sleeved at both ends of the second rotating shaft 15, and support rods 17 are fixedly connected to the first rotating sleeves 16 on both sides, and a rotating seat 2 is fixedly connected to the end of the support rod 17 away from the first rotating sleeve 16, and a clamping assembly 3 is rotatably connected to the rotating seat 2.

[0027] The support rods 17 on both sides are fixedly connected, and the preferred connection position is in the middle of the two support rods 17, so that the two support rods 17 will not be affected by the rotation of the two support rods 17 relative to the bracket 1 through the second rotating shaft 15 and the first rotating sleeve 16, and they can be kept synchronous during the rotation. When in use, the clamping assembly 3 can be clamped on the steel structure profile to be cut, and is located on both sides of the cutting position, so that when the bracket 1 and the shield 11 are pressed downward and rotated relative to the support rods 17, the steel structure profile can be gradually approached and cut. As the cutting process progresses, the edges of the steel structure profiles cut on both sides of the blade 14 will not curl due to external forces, so the cutting effect is better and the manual operation is more convenient.

[0028] Further, such as Figure 4-Figure 6 As shown, the clamping assembly 3 includes a third rotating shaft 31 rotatably connected to the rotating seat 2, and the outer periphery of the part of the third rotating shaft 31 extending into the rotating seat 2 is embedded with a tooth groove 33, and the middle outer periphery of the third rotating shaft 31 is fixedly connected with a sleeve 32, and the lower end of the sleeve 32 is fixedly connected with a first clamping plate 34, and the first clamping plate 34 is symmetrically provided with a telescopic sleeve 37, one end of the telescopic sleeve 37 passes through the first clamping plate 34 and the opening is flush with the surface of the first clamping plate 34, and an elastic rod 38 is slidably fitted at one end of the opening of the telescopic sleeve 37, and the elastic rod 38 is connected to the telescopic sleeve 37 by a spring, and the end of the elastic rod 38 away from the telescopic sleeve 37 is fixedly connected with a second clamping plate 35, and a plurality of groups of rollers 36 are rotatably connected to the second clamping plate 35, and the surface of the rollers 36 is movably fitted with the surface of the first clamping plate 34.

[0029] When this embodiment is in use, the third rotating shaft 31 and the rotating seat 2 can be relatively rotated to adjust the angle, and the second clamping plate 35 can be adjusted to a relative distance through the elastic cooperation of the elastic rod 38 and the telescopic sleeve 37, so that it is used to clamp the steel structure profile. The roller 36 can be used to facilitate clamping and placement. When batch processing of steel structure profiles is carried out, the placement efficiency can be improved. Furthermore, in order to improve the efficiency of batch processing and avoid repeated adjustment of the relative distance between the second clamping plate 35 and the first clamping plate 34, a sealing knob 39 is provided on the end of the telescopic sleeve 37 away from the second clamping plate 35 through a threaded connection, and a sealing ring is embedded in the outer periphery of the end of the elastic rod 38 extending into the telescopic sleeve 37. In this way, when adjusting the distance between the second clamping plate 35 and the first clamping plate 34, the sealing knob 39 can be removed in advance. After the adjustment, the sealing knob 39 is screwed on to form a sealed space between the elastic rod 38 in the telescopic sleeve 37 and the bottom of the telescopic sleeve 37. The distance between the elastic rod 38 and the bottom of the telescopic sleeve 37 can be fixed, so that batches of steel structure profiles can be cut and processed conveniently. The first clamping plate 34 and the second clamping plate 35 can clamp the steel structure profiles on both sides of the cutting position to avoid curling caused by force during cutting. After cutting, because the rollers 36 can rotate relative to each other, the first clamping plate 34 and the second clamping plate 35 can be vertically removed to continue processing the next group of steel structure profiles.

[0030] In order to achieve the fixation of the clamping distance, there can also be another set of embodiments, such as Figure 7 As shown, the clamping assembly 3 includes a third rotating shaft 31 rotatably connected to the rotating seat 2, and the outer periphery of the third rotating shaft 31 extending into the rotating seat 2 is embedded with a tooth groove 33, and a sleeve 32 is fixedly connected to the outer periphery of the middle part of the third rotating shaft 31, and a first clamping plate 34 is fixedly connected to the lower end of the sleeve 32, and a guide sleeve 3701 and a threaded sleeve 3703 are symmetrically provided on both sides of the first clamping plate 34, the guide sleeve 3701 passes through the first clamping plate 34, and a guide rod 3702 is slidably provided in the guide sleeve 3701, the threaded sleeve 3703 is rotatably connected to the first clamping plate 34, and a threaded rod 3704 is movably connected in the threaded sleeve 3703 through threaded cooperation, the threaded rod 3704 and the guide rod 3702 are fixedly connected with a second clamping plate 35 on the same side ends, and a plurality of groups of rollers 36 are rotatably connected to the second clamping plate 35, and the surface of the rollers 36 is movably fitted with the surface of the first clamping plate 34.

[0031] In this embodiment, the threaded sleeve 3703 can be rotated to drive the threaded rod 3704 to move relative to each other, and the guide rod 3702 slides in the guide sleeve 3701, thereby adjusting the spacing between the second clamping plate 35 and the first clamping plate 34, and self-locking can be achieved through the threaded cooperation between the threaded sleeve 3703 and the threaded rod 3704. This is simple and convenient to operate, the spacing adjustment is also very simple, and batch matching and processing of steel structure profiles can also be achieved.

[0032] Based on the above two solutions, Figure 8 As shown, the rotating seat 2 includes a second rotating sleeve 21 rotatably connected to the outer periphery of both ends of the third rotating shaft 31, the second rotating sleeve 21 is fixedly connected to the end of the support rod 17, a slide groove 22 is embedded on the upper side of the second rotating sleeve 21, and an elastic clip 23 is slidably provided in the slide groove 22, and the end of the elastic clip 23 extending into the slide groove 22 is provided with teeth corresponding to the tooth groove 33, the elastic clip 23 and the slide groove 22 are connected by a spring, and the end of the elastic clip 23 extending out of the slide groove 22 is fixedly connected with a gasket 24.

[0033] In this embodiment, the length of the support rod 17 is the cutting rotation radius of the device during cutting, that is, the rotating seat 2 is located on the trajectory of the blade 14 rotating and cutting through the bracket 1 and the shield 11, and the curvature of the gasket 24 matches the surface curvature of the first rotating shaft 13. When cutting, the third rotating shaft 31 can freely rotate relative to the second rotating sleeve 21, so that the bracket 1, the shield 11 and the blade 14 can realize relative rotation with the support rod 17 through the cooperation of the second rotating shaft 15 and the first rotating sleeve 16. In this process, the clamping assembly 3 can be freely adjusted through the rotating seat 2, and the cutting is flexible and stable and will not be affected. After processing, the first rotating shaft 13 parts on both sides of the blade 14 can be placed on the gasket 24, and under the action of gravity, the elastic clamping strip 23 is pressed against the tooth groove 33, thereby locking the relative angle between the third rotating shaft 31 and the second rotating sleeve 21, and the third rotating shaft 31 no longer rotates relative to the second rotating sleeve 21, and the placement is more stable.
