Description

A profile cutter for construction sites Technical Field

[0001] This invention relates to the field of profile processing equipment technology, specifically a profile cutter for construction sites. Background Technology

[0002] Profiles are made of iron or steel, as well as materials with certain strength and toughness (such as plastics, aluminum, and fiberglass), through processes such as rolling, extrusion, and casting. Profiles have fixed dimensions, a specific cross-sectional shape, and certain mechanical and physical properties. They can be used alone or further processed into other manufactured products and are commonly used in building structures and manufacturing installations.

[0003] During construction, profiles need to be cut using a cutting machine. Most existing cutting machines can only perform straight-line cutting, which is difficult to meet the needs of cutting at different angles. Therefore, there is an urgent need for a profile cutter for construction sites to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a profile cutter for construction sites to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A profile cutter for construction sites includes a fixed base plate and a cutting blade. The cutting blade is disposed on the top of the fixed base plate and connected to the output end of a drive component. The cutting blade is rotatably connected to a fixed sleeve, and the fixed sleeve is connected to one end of a telescopic component. The device also includes:

[0007] An angle adjustment mechanism, with one end connected to the fixed base plate and the other end connected to the other end of the telescopic component, is used to adjust the cutting angle of the cutting blade;

[0008] The support mechanism is connected to the fixed base plate and is located at the bottom of the fixed base plate to support the profile.

[0009] The fixing mechanism, connected to the fixing base plate, is used to fix the profile;

[0010] The protective mechanism, with one end connected to the cutting blade and the other end connected to the angle adjustment mechanism, is used to protect the cutting blade when it is not in use.

[0011] The angle adjustment mechanism includes:

[0012] The transverse angle adjustment component is connected to the fixed base plate and is used to adjust the transverse cutting angle of the cutting blade.

[0013] The fixed folding rod is connected to the lateral angle adjustment component and the protective mechanism;

[0014] The longitudinal angle adjustment component is connected to a fixed folding rod at one end and to a telescopic component at the other end, and is used to adjust the longitudinal cutting angle of the cutting blade.

[0015] As a further aspect of the present invention: the lateral surface angle adjustment component includes:

[0016] A rotating disk is located at the center of a fixed base plate and is rotatably connected to it. A cutting groove is provided at the center of the rotating disk, and the cutting groove and the cutting blade are in the same vertical plane.

[0017] The first threaded rod is threadedly connected to the fixed base plate;

[0018] The first fixed arc plate is rotatably connected to the first threaded rod and slidably connected to the fixed base plate. The first fixed arc plate is used to abut and fix the rotating disk.

[0019] As a further aspect of the present invention: the longitudinal plane angle adjustment component includes:

[0020] The rotating block is rotatably connected to the fixed folding rod and to the other end of the telescopic component;

[0021] The second threaded rod is rotatably connected to the rotating block;

[0022] A threaded sleeve, which is threadedly connected to the second threaded rod;

[0023] The limiting telescopic rod is connected to the rotating block at one end and to the threaded sleeve at the other end. It is used to limit the movement of the threaded sleeve and ensure its stable movement.

[0024] The second fixed arc plate is connected to the threaded sleeve and abuts against the fixed folding rod.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] In the initial state, the protective mechanism protects the cutting blade. When cutting the profile, the support mechanism supports the profile, the transverse angle adjustment component adjusts the transverse cutting angle of the cutting blade, the longitudinal angle adjustment component adjusts the longitudinal cutting angle of the cutting blade, the fixing mechanism fixes the profile, the driving component drives the cutting blade to rotate, the telescopic component drives the fixing sleeve to move longitudinally, and thus drives the cutting blade and the protective mechanism to move longitudinally. At the same time, the protective mechanism opens, exposing the cutting blade, which then cuts the profile. This solves the problem that most existing cutters can only perform straight-line cutting and cannot meet the needs of cutting at different angles. Attached Figure Description

[0043] As an embodiment of the present invention, please refer to FIG1, the lateral surface angle adjustment component 61 includes:

[0044] A rotating disk 611 is located at the center of a fixed base plate 1 and is rotatably connected to it. A cutting groove is provided at the center of the rotating disk 611, and the cutting groove and the cutting blade 2 are in the same vertical plane.

[0054] Rotating block 631 drives cutting blade 2 to rotate, adjusting its cutting angle. After adjustment, rotating second threaded rod 632 drives threaded sleeve 633 to move longitudinally under the limit of telescopic rod 634. Threaded sleeve 633 drives second fixed arc plate 635 to move, causing second fixed arc plate 635 to abut against fixed folding rod 62, thereby limiting and fixing rotating block 631, and thus limiting and fixing cutting blade 2.

[0066] The fixing block 86 is connected to the U-shaped slide bar 85.

[0067] The profile is placed on the rotating disk 611 and abuts against the limiting plate 81. The rotating sleeve 84 is rotated and the U-shaped slide bar 85 is slid, thereby adjusting the fixed position of the fixing block 86. The threaded rotating sleeve 83 is rotated, causing the threaded rotating sleeve 83 to move longitudinally, which in turn drives the fixing block 86 to move longitudinally, so that the fixing block 86 abuts against the profile and fixes it.

[0068] As one embodiment of the present invention, please refer to Figures 1 and 3. The protective mechanism 9 includes:

[0069] The first protective cover 91 is rotatably connected to the cutting blade 2, and the first protective cover 91 is a semi-circular arc cover;

[0072] When the cutting blade 2 is not in use, the first protective cover 91 and the second protective cover 92 work together to protect the cutting blade 2, preventing it from being exposed to the air and preventing workers from accidentally touching the cutting blade 2 and getting injured. When the cutting blade 2 needs to cut, the telescopic component 5 drives the fixed sleeve 4 to move longitudinally, which in turn drives the cutting blade 2, the first protective cover 91 and the second protective cover 92 to move longitudinally. Under the pulling force of the return spring 93, the first protective cover 91 and the second protective cover 92 rotate simultaneously, exposing the cutting blade 2 for cutting.

[0073] In one embodiment of the present invention, the fixed base plate 1 is provided with a first angle scale line, which is coaxially arranged with the rotating disk 611. The rotating disk 611 is provided with a first pointer for precisely controlling the rotation angle of the rotating disk 611. The fixed folding rod 62 is provided with a second angle scale line, which is coaxially arranged with the rotating block 631. The rotating block 631 is provided with a second pointer for precisely controlling the rotation angle of the rotating block 631.

[0074] The working principle of this invention is as follows: when the cutting blade 2 is not in use, the first protective cover 91 and the second protective cover 92 work together to protect the cutting blade 2, preventing the cutting blade 2 from being exposed to the air and preventing workers from accidentally touching the cutting blade 2 and getting injured.

[0075] During cutting, the rotating disk 611 rotates, causing the fixed bending rod 62 to rotate, which in turn drives the cutting blade 2 to rotate, adjusting its transverse angle. After adjustment, the first threaded rod 612 rotates, causing the first fixed arc plate 613 to move, so that the first fixed arc plate 613 abuts against the rotating disk 611, fixing the rotating disk 611. The rotating block 631 rotates, causing the cutting blade 2 to rotate, adjusting its cutting angle. After adjustment, the second threaded rod 632 rotates. Under the limitation of the limiting telescopic rod 634, the second threaded rod 632 drives the threaded sleeve 633 to move longitudinally, and the threaded sleeve 633 drives the second fixed arc plate 635 to move, making... The second fixed arc plate 635 abuts against the fixed folding rod 62, thereby limiting and fixing the rotating block 631, and thus limiting and fixing the cutting blade 2. The sliding support rod 72 is pulled out from the fixed cylinder 71. The pulling distance of the sliding support rod 72 is controlled according to the length of the profile. The profile is placed on the rotating roller 73 and the rotating disk 611 to support the profile. The profile is placed on the rotating disk 611 and abuts against the limiting plate 81. The rotating sleeve 84 is rotated and the U-shaped sliding rod 85 is slid, thereby adjusting the fixed position of the fixed block 86. The threaded rotating sleeve 83 is rotated, causing the threaded rotating sleeve 83 to move longitudinally, thereby driving the fixed block 86 to move longitudinally, so that the fixed block 86 abuts against the profile and fixes it.

[0076] The telescopic component 5 drives the fixed sleeve 4 to move longitudinally, which in turn drives the cutting blade 2, the first protective cover 91 and the second protective cover 92 to move longitudinally. Under the pulling force of the return spring 93, the first protective cover 91 and the second protective cover 92 rotate simultaneously, exposing the cutting blade 2. The driving component 3 drives the cutting blade 2 to rotate and cut the profile.
