Description

Technical Field

[0001] The utility model relates to the technical field of steel profile processing equipment, in particular to a length-fixing device for steel profiles. Background Art

[0002] Steel profiles, also known as steel sections, refer to strip-shaped steel with certain cross-sectional shapes and sizes. They are widely used in various building structures and engineering structures. In the process of using steel profiles, in order to meet people's needs, they usually need to be cut. However, when cutting, since people usually have specific requirements for their length, a fixed-length device is needed to limit the length required for cutting.

[0003] The inventor discovered during the process of implementing the utility model:

[0004] The patent document with announcement number CN217414190U discloses a length-fixing device for plastic-steel profiles, which can quickly position the plastic-steel profiles through a rapid shaping device provided on the equipment, and then quickly cut the plastic-steel profiles by a fixed-length cutting mechanism. In addition, the servo operation system increases the accuracy of the equipment during operation, facilitating better processing of materials.

[0005] However, in actual applications, in order to facilitate the subsequent splicing of steel profiles, the cross-section of the steel profile after cutting is usually required to be inclined. However, in the technical solution of the above-mentioned patent, since there is no angle adjustment function for the cutting device, the cross-section of the steel profile after cutting can only be a vertical surface, which not only limits the scope of application of the device, but also reduces its practical value. At the same time, in the existing technology, people cannot observe the length after cutting more intuitively, which brings great inconvenience to people's use. Summary of the invention

[0006] In order to solve the problems existing in the prior art, the utility model provides a length fixing device for steel profiles.

[0007] To this end, the technical solution of the utility model is: a length-fixing device for steel profiles, comprising a workbench, characterized in that: a fixing frame is provided on one side of the workbench, and an inclined cutting mechanism is provided inside the fixing frame.

[0008] The inclined cutting mechanism comprises a bearing plate, which is connected to the inner top surface of the fixing frame through symmetrically arranged fixing legs, a motor is installed on the top surface of the bearing plate, the output end of the motor passes through the bearing plate and is fixedly connected to a bevel gear 1, a U-shaped pad is oppositely arranged on the bottom surface of the bearing plate, a rotating rod is rotatably connected between the two U-shaped pads, a bevel gear 2 is fixedly connected to the outer surface of the rotating rod, and the bevel gear 1 is meshed with the bevel gear 2;

[0009] Connecting plates are fixed on both sides of the rotating rod, a mounting plate is fixed on the other end of the connecting plate, a hydraulic telescopic cylinder extending in the opposite direction is installed on the side of the mounting plate away from the connecting plate, and a cutting assembly is installed on the output end of the hydraulic telescopic cylinder.

[0010] A further improvement to the above technical solution is that: a positioning plate is also provided on the workbench, and a threaded block is fixedly connected to the bottom surface of the positioning plate. The threaded block is slidably connected to a slide groove in the length direction of the workbench and extends to the bottom of the workbench; the threaded block is slidably connected to the inner wall of the workbench through a reserved slide groove and extends to the bottom of the workbench. When cutting the steel profile, one end of the steel profile must be in contact with the surface of the positioning plate.

[0011] A further improvement to the above technical solution is that a threaded screw is arranged under the workbench, and a threaded block is threadedly connected to the threaded screw; as the threaded screw rotates, the threaded block can be driven to move, thereby adjusting the position of the positioning plate to determine the required length of the steel profile.

[0012] A further improvement to the above technical solution is that: the two ends of the threaded screw are rotatably connected to two fixed blocks, the fixed blocks are fixed to the bottom surface of the workbench, and one end of the threaded screw is fixedly connected to a handle. By setting the handle, the threaded screw can be controlled more conveniently, and the fixed block can support the threaded screw.

[0013] A further improvement to the above technical solution is that: the positioning plate is installed with relatively arranged electric telescopic rods on one side close to the fixed frame, and the output ends of the two electric telescopic rods are fixed with inverted T-shaped clamping plates; when cutting the steel profile, the electric telescopic rod must be started to drive the two clamping plates closer to each other, thereby achieving the fixation of the steel profile during the cutting process.

[0014] A further improvement to the above technical solution is that: pointers extending in opposite directions are provided at the lower parts of both ends of the positioning plate, and scales are provided on the front and rear end surfaces of the workbench; the movement of the positioning plate can drive the movement of the pointer, and the scale indicated by the pointer on the scale enables people to more intuitively observe the length of the steel profile after cutting.

[0015] Beneficial effect: The utility model can adjust the angle of the cutting assembly through the coordinated arrangement among the workbench, the fixing frame, the inclined cutting mechanism, the positioning plate, the pointer and the scale, so that the cross-section of the steel profile after cutting is inclined, which not only expands the application scope of the device, but also further improves the practical value of the device, and at the same time enables people to observe the length after cutting more intuitively, making it more convenient for people to use; through the coordinated arrangement among the threaded block, the threaded screw, the positioning plate, the pointer and the scale, people can observe the length of the steel profile after cutting more intuitively, and the rotation of the threaded screw can drive the movement of the threaded block, thereby realizing the adjustment of the position of the positioning plate. At this time, the pointer can move with the positioning plate. When people need to observe the length of the steel profile after cutting, they only need to observe the scale value indicated by the pointer on the scale to intuitively observe the length of the steel profile after cutting.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings, but this embodiment should not be understood as a limitation to the present invention.

[0022] The utility model Figures 1 to 4 As shown:

[0023] A device for fixing the length of steel profiles, comprising a workbench 1, a reserved slide groove is provided on the upper surface of the workbench 1, a fixing frame 2 is provided on one side of the workbench 1, an inclined cutting mechanism 3 is provided inside the fixing frame 2, and the inclined cutting mechanism 3 is provided so that the cross section of the steel profile after cutting can be inclined, the inclined cutting mechanism 3 comprises a bearing plate 301, a rotating rod 305 and a mounting plate 309, and the outer surface of the bearing plate 301 is fixedly connected with symmetrical fixing legs 302, and the two fixing legs 302 are fixedly connected to the inner top surface of the fixing frame 2;

[0024] A motor 303 is installed on the top surface of the bearing plate 301. The output end of the motor 303 penetrates the bearing plate and is fixedly connected with a bevel gear 1 304. The output end of the motor 303 penetrates the bearing plate 301 and is rotatably connected to the bearing plate 301. By starting the motor 303, the bevel gear 1 304 can be driven to rotate. The outer surface of the rotating rod 305 is rotatably connected with a symmetrical U-shaped pad 306. Both U-shaped pads 306 are fixedly connected to the bottom surface of the bearing plate 301. The U-shaped pad 306 can support the rotating rod 305. The outer surface of the rotating rod 305 is fixedly connected with a bevel gear 2 307. The bevel gear 1 304 is meshed with the bevel gear 2 307. As the bevel gear 2 307 rotates, the bevel gear 1 304 can be driven to rotate.

[0025] A symmetrical connecting plate 308 is fixedly connected to the outer surface of the mounting plate 309, and the two connecting plates 308 are fixedly connected to the outer surface of the rotating rod 305. A hydraulic telescopic cylinder 310 is installed on the outer surface of the mounting plate 309, and a cutting component 311 is installed on the output end of the hydraulic telescopic cylinder 310. When cutting, the cutting component 311 can be driven to move downward as the hydraulic telescopic cylinder 310 is started, thereby completing the cutting of the steel profile. A cutting knife is installed inside the cutting component 311, and the power source is a motor. With the rotation of the cutting knife and the pushing action of the hydraulic telescopic cylinder 310, the steel profile can be cut.

[0026] like Figure 3 As shown, a positioning plate 4 is also provided on the workbench 1, and a threaded block 5 is fixedly connected to the bottom surface of the positioning plate 4. The threaded block 5 is slidably connected to the inner wall of the workbench 1 and extends to the bottom of the workbench 1. The threaded block 5 is slidably connected to the inner wall of the workbench 1 and extends to the bottom of the workbench 1 through a reserved groove opened on the upper surface of the workbench 1. When cutting the steel profile, one end of the steel profile must be in contact with the surface of the positioning plate 4.

[0027] like Figure 3 As shown, a threaded screw 6 is provided below the workbench 1, and a threaded block 5 is threadedly connected to the outer surface of the threaded screw 6. As the threaded screw 6 rotates, the threaded block 5 can be driven to move, thereby adjusting the position of the positioning plate 4 to determine the required length of the steel profile;

[0028] The two ends of the threaded screw 6 are rotatably connected to two fixed blocks 7, and the two fixed blocks 7 are fixedly connected to the bottom surface of the workbench 1. One end surface of the threaded screw 6 is fixedly connected to a handle 8. By setting the handle 8, the threaded screw 6 can be more conveniently controlled, and the fixed block 7 can support the threaded screw 6.

[0029] like Figure 3 As shown, symmetrical electric telescopic rods 9 are installed on the outer surface of the positioning plate 4, and the output ends of the two electric telescopic rods 9 are fixedly connected to the clamping plates 10. When cutting the steel profile, the electric telescopic rods 9 must be started to drive the two clamping plates 10 to move closer to each other, thereby achieving the fixation of the steel profile during the cutting process.

[0030] like Figure 1 As shown, a symmetrical pointer 11 is fixedly connected to the outer surface of the positioning plate 4, and a symmetrical scale 12 is fixedly connected to the outer surface of the workbench 1. The movement of the positioning plate 4 can drive the movement of the pointer 11. The scale indicated by the pointer 11 on the scale 12 allows people to more intuitively observe the length of the steel profile after cutting.

[0031] The working principle of this utility model:

[0032] When in use, first rotate the threaded screw 6 through the handle 8, thereby driving the movement of the threaded block 5 to adjust the position of the positioning plate 4. At this time, the scale indicated by the pointer 11 on the scale 12 must match the required length of the steel profile. Then the steel profile is passed through the bottom of the fixed frame 2, and one end is in contact with the outer surface of the positioning plate 4. The electric telescopic rod 9 is started to drive the clamping plate 10 to move, and the steel profile is clamped by the two clamping plates 10, thereby achieving a fixed length of the steel profile.

[0033] When people need to cut the cross section of the steel profile into an inclined shape, they only need to start the motor 303 to drive the rotation of the bevel gear 1 304, and then drive the rotation of the bevel gear 2 307, thereby driving the rotation of the rotating rod 305, and then the mounting plate 309 can be driven to flip until the cutting knife in the cutting assembly 311 is parallel to the required inclined cross-sectional angle, and then by starting the hydraulic telescopic cylinder 310 and the cutting assembly 311, under the driving action of the hydraulic telescopic cylinder 310 and the rotation action of the cutting knife inside the cutting assembly 311, the cross section of the steel profile after cutting is made inclined, which not only expands the scope of application of the device, but also further improves the practical value of the device. When people need to observe the length of the steel profile after cutting, they only need to use the scale value indicated by the pointer 11 on the scale 12, so that people can more intuitively observe the length of the steel profile after cutting, which makes it more convenient for people to use.

[0034] Parts not described in detail in this specification are well-known technologies in the art.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
