Description

Technical Field

[0001] This utility model relates to the technical field of shearing machines or shearing devices that use rotary disc cutters for cutting, and particularly to a profile cutting machine that uses an iron bracket limiting device. Background Technology

[0002] Profile cutting machines, also known as abrasive wheel saws, are suitable for use in construction, hardware, petrochemical, machinery and metallurgy, and water and electricity installation industries. They are commonly used equipment for cutting materials such as metal square and flat tubes, square and flat steel, I-beams, channel steel, carbon steel, and round tubes. Chinese utility model patent, authorized publication number "CN221658081U," discloses a profile cutting machine using an iron bracket limiting device. This utility model controls the downward pressure of the handle motor, causing the slider to move downwards along the groove, thus facilitating the cutting of profiles of different heights and effectively improving cutting efficiency.

[0003] While the above-mentioned technical solution effectively reduces manufacturing costs and improves operational convenience through the integrated design of the iron bracket and the limiting device, it still has shortcomings in terms of protective structure. During operation, this type of cutting machine often generates a large amount of debris and sparks, posing a potential threat to the safety of operators. At the same time, the protective structure is prone to wear and tear under long-term operation, and once damaged, the replacement process is often complicated and time-consuming, affecting the overall efficiency of the equipment. Therefore, we propose a profile cutting machine with an iron bracket limiting device. Utility Model Content

Although the integrated design of the iron bracket and the limiting device effectively reduces manufacturing costs and improves the ease of operation, there are still shortcomings in the protective structure. During operation, such cutting machines often generate a large amount of debris and sparks, which pose a potential threat to the safety of operators. At the same time, the protective structure is prone to wear and tear under long-term operation. Once damaged, the replacement process is often complicated and time-consuming, which affects the overall efficiency of the equipment.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a profile cutting machine using an iron bracket limiting device, comprising:

[0028] Profile cutting table 1, the top of profile cutting table 1 is provided with a cutting groove;

[0029] A cutting protection structure is located on the profile cutting table 1.

[0030] The cutting protection structure includes a support frame 2, a connecting arm 15, a tool mounting shell 12, a protective plate 10, and an arc-shaped plate 16. The support frame 2 is fixedly connected to the top of the profile cutting table 1. The connecting arm 15 is rotatably connected inside the support frame 2. The end of the connecting arm 15 away from the support frame 2 is fixedly connected to the tool mounting shell 12. An arc-shaped groove 14 is provided on one side of the tool mounting shell 12. The arc-shaped plate 16 is slidably connected inside the arc-shaped groove 14. The protective plate 10 is fixedly connected to the side of the arc-shaped plate 16 away from the tool mounting shell 12. The protective plate 10 is fixedly installed on the tool mounting shell 12 by bolts.

[0031] The cutting blade 9 is installed inside the tool mounting housing 12. A drive motor 13 is fixedly installed on the side of the tool mounting housing 12 away from the protective plate 10. The output end of the drive motor 13 rotates and extends into the interior of the tool mounting housing 12 and is fixedly connected to the cutting blade 9. A limit mounting bracket 3 is fixedly connected to the top of the support frame 2. A spring 17 is fixedly connected inside the limit mounting bracket 3. The end of the spring 17 away from the limit mounting bracket 3 is fixedly connected to the connecting arm 15.

[0032] The top of the profile cutting table 1 is rotatably connected to a telescopic rod 4. The top end of the telescopic rod 4 is rotatably connected to the side of the connecting arm 15 away from the spring 17. A handle 11 is fixedly connected to the outer surface of the tool mounting housing 12. A fixed clamping plate 5 and a fixed plate 7 are fixedly connected to the top of the profile cutting table 1. An electric push rod 8 is fixedly installed on the side of the fixed plate 7 away from the fixed clamping plate 5. The telescopic end of the electric push rod 8 slides through the fixed plate 7 and is fixedly connected to a movable clamping plate 6.

[0033] Furthermore, when using the device, by connecting an external power source to start the drive motor 13 and the electric push rod 8, the electric push rod 8 will drive the movable clamping plate 6 to move, so that the movable clamping plate 6 can clamp and fix the profile on the clamping plate 5, thereby facilitating the clamping and fixing of the profile. The drive motor 13 will drive the cutting blade 9 to rotate, so that the operator holds the handle 11 and moves the tool mounting housing 12 downward. The tool mounting housing 12 will drive the connecting arm 15 to rotate around the rotation point with the support frame 2. The rotation of the connecting arm 15 will drive the telescopic rod 4 to rotate and retract simultaneously. To facilitate the cutting of the profile by the cutting blade 9, the connecting arm 15 rotates and pulls the spring 17 to stretch it. After the cutting blade 9 finishes cutting, the tool mounting shell 12 will return to its original position under the pull of the spring 17, so that the telescopic rod 4 can limit the rotation angle of the tool mounting shell 12. When disassembling the protective plate 10, the operator removes the two bolts on the protective plate 10. Then, the protective plate 10 drives the arc plate 16 to slide inside the arc groove 14, which makes it easy to remove the protective plate 10 and facilitate the maintenance of the internal parts of the protective device.

[0034] With the cooperation of the tool mounting shell 12, the arc plate 16 and the protective plate 10, the tool mounting shell 12 and the protective plate 10 can protect the cutting blade 9 when cutting. Since the protective plate 10 is detachable, it can be easily removed from the cutting machine, which facilitates the maintenance of the internal parts of the protective plate 10 and the tool mounting shell 12 and the replacement when necessary. This reduces the reliance on professional technicians, greatly shortens the replacement time, and improves the convenience of replacing the protective plate 10.

[0035] Structural description: Support frame 2: It can support the tool mounting shell 12 and facilitate the rotation of the connecting arm 15 inside it;

[0036] Limiting mounting bracket 3: It has a "C" structure and is used to install spring 17;

[0037] Telescopic rod 4: It is composed of multiple telescopic sliding rods and can limit the rotation angle of the tool mounting shell 12;

[0038] Protective plate 10: It can protect the operator from sparks and debris when the cutting blade 9 is cutting;

[0039] Handle 11: makes it easy for the operator to hold and operate the cutting blade 9;

[0040] Tool mounting housing 12: facilitates the installation of the cutting blade 9;

[0041] Arc groove 14: can limit the arc plate 16, thereby facilitating the installation of the protective plate 10.

[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
