Description

Technical Field

[0001] This utility model relates to a cutting device, specifically an improved positioning and protective cutting device, belonging to the field of building engineering technology. Background Technology

[0002] In small-scale projects, when using cutting machines to cut materials such as rebar and steel pipes, it is often necessary to cut the materials to precise lengths according to the drawings. However, many construction sites lack fully automated cutting machines, thus relying on manual operation for the cutting work. This manual control of the cutting length is not only inefficient but also susceptible to human error, leading to material waste or inaccurate cutting. Existing cutting devices lack corresponding workpiece fixing devices during the cutting process, making it easy for the workpiece to move or shift, resulting in inaccurate cutting and failure to meet the precise length required by the drawings. Furthermore, rebar is prone to vibration during cutting, especially at high speeds. Vibration makes the cutting process more difficult to control, and especially during prolonged use, equipment vibration can lead to operational instability, increasing the risk of operator injury; the rebar may also dislocate due to vibration, causing unnecessary danger.

[0003] A search revealed a rebar cutting machine disclosed in Chinese patent document CN206868984U. The machine includes a cutting body and a clamping device mounted on the cutting body. The cutting body includes a base and a cutting tool assembly fixedly connected to the base. The cutting tool assembly includes a saw blade. A measuring device is mounted on the base, comprising a limit ruler and a limit block fixed to one end of the limit ruler near the saw blade. The limit block extends to the front of the clamping device. This rebar cutting machine allows for real-time measurement of the rebar using a measuring device mounted on the cutting body, enabling users to easily and quickly determine the required finished rebar length and improving work efficiency. However, during use, the clamping and fixing efficiency is not high, and for longer rebars, the lack of a corresponding support device easily leads to a shift in the center of gravity, making cutting cumbersome.

[0004] Therefore, the key to solving the above-mentioned technical problems lies in developing a safe, reliable, and highly accurate cutting positioning and protection device. Summary of the Invention

[0005] In view of the many defects and shortcomings existing in the above-mentioned background technology, this utility model has made improvements and innovations, with the aim of providing a cutting positioning and protection device that is simple to operate, safe and reliable, which can improve cutting accuracy and efficiency, and ensure operational safety.

[0095] The fixing mechanism is set on the operating platform 22 at one end of the positioning plate 23, and works with the positioning plate 23 to fix the workpiece 7 to be cut.

[0096] The cutting machine 1 is connected above the other end of the operating platform 22.

[0097] Specifically, the fixing mechanism includes:

[0098] The fixed seat 24 is connected to the upper surface of the operating platform 22 at the end away from the cutting machine 1, and the fixed seat 24 has an internal thread section through the middle;

[0118] In the present utility model, the hanging piece 41 is integrally in a "C" - shaped structure, and a hanging groove adapted to the hanging piece 41 is provided on the hanging seat 42.

[0119] Furthermore, the moving seat 5 is integrally in a "匚" - shaped structure. The moving seat 5 is slidably and snap - connected above the width direction of the support frame 311. Wherein, tightening members 51 are threadedly connected to both ends of the moving seat 5, and the tightening members 51 are used to limit the movement of the moving seat body on the support frame 311.

[0120] Furthermore, the positioning and buffering member 6 includes:

[0121] A positioning seat 61, the lower end of the positioning seat 61 is slidably connected to the moving seat 5, and a threaded locking hole is also through - opened on one side plate at the lower end of the positioning seat 61;

[0122] A locking member 62, which is threadedly connected to the threaded locking hole;

[0123] A sleeve 63, which is connected in a communicating manner to the inner side of the upper side plate of the positioning seat 61;

[0124] A buffering component, which is respectively connected to the sleeve 63 and the upper side plate of the positioning seat 61.

[0125] Specifically, the buffering component includes:

[0126] A buffer rod 64, the middle section of the buffer rod 64 is sleeved in the sleeve 63;

[0127] A stop block 65, which is connected to the end of the buffer rod 64 near the cutting machine operation table 2 end;

[0128] The buffer adjusting nut 66 is threadedly connected to the non-stop end of the buffer rod 64;

[0129] The buffer spring 67 has two ends connected to the buffer adjusting nut 66 and the side plate above the positioning seat 61 via connecting rings.

[0130] Before use, the operator first installs the support frame 3 on the cutting machine operating table 2 through at least one connecting component 4, connecting them as one unit;

[0131] In use: First, the operator adjusts the position of the stop block 65 according to the cutting length requirement of the workpiece 7 to be cut. During adjustment, the operator first moves the movable seat 5 to the designated position, and then uses the clamping member 51 to firmly connect the movable seat 5 to the support frame 311. Then, the operator places the workpiece 7 to be cut on the operating platform 22 and connects it to the positioning plate 23. Then, the operator moves the positioning seat 61 and moves the stop block 65 to the end position of the workpiece 7 to be cut. Then, the locking member 62 firmly connects the positioning seat 61 to the movable seat 5.

[0132] Then, the operator makes contact with the stop block 65 at one end of the workpiece 7 to be cut;

[0133] Next, the operator rotates the adjusting plate 27 to drive the adjusting rod 25 to rotate on the fixed base 24, which in turn drives the clamping plate 26 to move until the clamping plate 26 contacts and connects with the outer wall of the workpiece 7 to be cut.

[0134] Finally, the operator can use the cutting machine 1 to cut the workpiece 7.

[0135] In the above-described process, if a batch of workpieces 7 of the same length and specifications are to be cut, the cutting is performed according to the above method. After the cutting is completed, the cut workpiece can be removed by slightly loosening the adjusting plate 27. When cutting the next workpiece 7, one end of the workpiece 7 is connected to the stop block 65, and then the workpiece 7 is fixed by loosening the adjusting plate 27. The workpiece 7 can then be cut quickly. The above operation procedure can be followed to cut a batch of workpieces 7 of the same length and specifications.

[0136] If you are cutting workpieces 7 of different lengths and the same specifications, you can start cutting them after adjusting them according to the above method.

[0137] If the ground is uneven during the above-mentioned use, the operator can level it by adjusting the support 33 at the bottom of the support frame 3.

[0138] During the above-mentioned use, the operator can adjust the elastic strength of the buffer spring 67 by adjusting the buffer adjusting nut 66 on the buffer rod 64. When adjusting, the operator rotates the buffer adjusting nut 66 to adjust the distance between the stop block 65 and the adjusting nut 66, thereby causing the buffer spring 67 to stretch or contract, thus adjusting the elastic strength of the buffer spring 67. This affects the elastic strength of the buffer spring 67, ensuring that the equipment performs optimized elastic adjustment according to the load and demand during operation to achieve the best buffering effect and avoid problems such as excessive vibration or insufficient buffering.

[0139] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
