[0002] In industrial fields such as shelving manufacturing that involve square tube cutting, circular saws are commonly used cutting equipment, and their cutting efficiency and stability directly affect the overall production process and product quality.

[0003] Currently, circular saws on the market have significant technical shortcomings in square tube cutting. Specifically, current circular saws typically only have the capability to cut single square tubes one at a time. Faced with the large demand for square tube processing and cutting in large-scale production scenarios such as shelving manufacturing, this single-tube cutting method is extremely inefficient and cannot meet the urgent need for efficient processing in actual production.

[0004] Meanwhile, during the cutting process, existing circular saws lack effective workpiece fixing devices, requiring operators to manually press down on both sides of the square tube to maintain workpiece stability. This operation method not only increases the labor intensity of workers, but also, because the force and stability of manual pressing are difficult to guarantee, it is very easy for the square tube to shift or shake during the cutting process, thereby affecting the cutting accuracy and causing quality problems such as cutting size deviation and uneven cut. In severe cases, it may even damage the circular saw equipment, increasing production costs and posing production safety hazards. Utility Model Content

Detailed Implementation

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0019] Please see Figure 1-7 The present invention provides the following technical solution: Example 1: For applications with high demand for square tube processing and cutting, existing circular saws typically only allow for sequential cutting of single square tubes, presenting a technical limitation in simultaneously cutting multiple square tubes. Furthermore, during the cutting process, operators must manually press down on both sides of the square tube to maintain workpiece stability, resulting in low cutting efficiency and a high degree of manual intervention.

[0020] The circular saw includes a housing 1, a baffle mechanism, a material blocking mechanism 2, and a cutting mechanism 3. The material blocking mechanism 2 is located on the top of the housing 1. The material blocking mechanism 2 includes a first limiting part 21, a displacement part 22, a locking part 23, and a pressing part 24. The first limiting part 21 has multiple parts and is slidably disposed on the top of the housing 1. The displacement part 22 has multiple parts and is disposed on the side of each first limiting part 21. The multiple displacement parts 22 are fixedly connected to the first limiting part 21, and the multiple displacement parts 22 and the first limiting part 21 together form a structure for abutting against both sides of the workpiece to be cut. The material blocking chamber is provided, and the top of the housing 1 is provided with a limiting groove for limiting the horizontal sliding of the displacement part 22; multiple locking parts 23 are respectively rotatably disposed on the top of the displacement part 22, and the locking parts 23 can drive the displacement part 22 to abut against the top of the housing 1 by screwing in; a pair of pressing parts 24 are respectively slidably disposed on the housing 1, and when the pair of pressing parts 24 slide, they can abut the top of the workpiece to be cut located between the first limiting part 21 and the displacement part 22; the cutting mechanism 3 is slidably disposed on the top of the housing 1.

[0021] In this embodiment, the workpiece to be cut is a square tube constituting a shelf. The operator first places the square tube to be cut into the retaining chamber formed by the first limiting part 21 and the displacement part 22, where the displacement part 22 serves to abut the workpiece. When multiple square tubes need to be cut, the operator first rotates the locking part 23 to release the tight connection between the first limiting part 21 and the displacement part 22 and the top of the housing 1; then, the paired first limiting part 21 and displacement part 22 are driven to slide closer together along the limiting groove on the top of the housing 1, thus adjusting the spacing between the square tubes by reducing the space of the retaining chamber. When the cutting mechanism 3 performs the cutting operation, the pressing part 24 descends synchronously and presses and fixes the tops of both sides of the square tube placed in the retaining chamber, effectively preventing the square tube from detaching or shifting due to force on the middle during the cutting process, ensuring the stability and accuracy of the cutting operation. This solves the technical problem that existing circular saws cannot cut multiple square tubes simultaneously and require manual pressing to maintain stability.

[0022] See Figure 2 and Figure 3 The material blocking mechanism 2 also includes a first telescopic cylinder 25 and a pushing part 26; the first telescopic cylinder 25 has a pair and is respectively disposed on the top of the housing 1, and the pair of first telescopic cylinders 25 are located on both sides of the cutting mechanism 3; the pushing part 26 has a pair and is respectively disposed at the output end of the pair of first telescopic cylinders 25, and the pair of pushing parts 26 are located on the side of the cutting mechanism 3, and the pair of pushing parts 26 are used to abut against the side of the workpiece to be cut.

[0023] In this embodiment, when the first telescopic cylinder 25 is activated, it drives the pushing part 26 to move horizontally, making it closely abut against the side of the workpiece to be cut. By applying lateral pressure to the workpiece through the pushing part 26, the lateral displacement of the workpiece during the cutting process is further restricted, enhancing the stability of the workpiece in the baffle chamber and ensuring cutting accuracy.

[0024] See Figure 6 The material blocking mechanism 2 also includes a mounting frame 27 and a second telescopic cylinder 28; the mounting frame 27 has a pair and is respectively disposed on the top of a pair of first limiting parts 21; the second telescopic cylinder 28 has a pair and is respectively disposed on the top of the mounting frame 27, and the output ends of the pair of second telescopic cylinders 28 are respectively connected to the top of a pair of pressing parts 24.

[0025] When the second telescopic cylinder 28 is activated, it drives the pressing part 24 to slide vertically, thereby pressing or releasing the top of the workpiece. By controlling the movement of the pressing part 24 with a cylinder, the automation level and response speed of the pressing operation are improved, further ensuring the fixation effect of the workpiece during the cutting process.

[0026] See Figure 7 The cutting mechanism 3 includes a first linear guide rail 31, a first linear slide 32, a positioning frame 33, a rotating frame 34, a rotary motor 35, and a cutting blade 36. The first linear guide rail 31 is a pair and is respectively disposed on the top of the housing 1. The first linear slide 32 is a pair and is respectively slidably disposed on the top of the first linear guide rail 31. The positioning frame 33 is disposed on the top of the pair of first linear slides 32. The rotating frame 34 is rotatably disposed on the top of the positioning frame 33. The rotary motor 35 is disposed on the top of the rotating frame 34. The cutting blade 36 is rotatably disposed on the top of the rotating frame 34, and the cutting blade 36 is located beside the rotary motor 35.

[0027] In this embodiment, the output end of the rotary motor 35 is connected to the input end of the cutting blade 36 via a synchronous pulley and a synchronous belt. The rotary motor 35 is preferably a servo motor. When the rotary motor 35 starts, it drives the cutting blade 36 to rotate via the synchronous pulley and synchronous belt, thereby enabling the cutting of the workpiece. Furthermore, to cut multiple square tubes, the first linear slide 32, under the constraint of the first linear guide rail 31, moves the rotary motor 35 and the cutting blade 36, thus completing the cutting of the multiple square tubes.

[0028] See Figure 7 The cutting mechanism 3 also includes an electric push rod 37 and a hinge rod 38. The electric push rod 37 is slidably disposed on the top of the housing 1, and the top of the housing 1 has an opening for moving the electric push rod 37. The end face of the electric push rod 37 is fixedly connected to the bottom of the positioning frame 33. The hinge rod 38 is rotatably disposed on the rotating frame 34. One end of the hinge rod 38 is rotatably connected to the bottom of the rotating frame 34, and the other end of the hinge rod 38 is rotatably connected to the top of the electric push rod 37. When the electric push rod 37 is started, the rotating frame 34 can be driven to flip through the hinge rod 38.

[0029] To allow the rotary motor 35 and the cutting blade 36 to descend and cut the tube, in this embodiment, the bottom of the housing 1 is provided with a cutting slot for the cutting blade 36 to pass through, and this cutting slot is located in the middle of the workpiece to be cut. When the electric push rod 37 is activated, it can drive the rotating frame 34 to flip on top of the positioning frame 33 through the rotatably connected hinge rod 38, thereby driving the rotary motor 35 and the cutting blade 36 to flip synchronously.

[0030] See Figure 7 The cutting mechanism 3 also includes a linear motor 39 and a ball screw 391; the linear motor 39 has a pair and is respectively disposed on the side of the first linear guide rail 31; the ball screw 391 has a pair and is respectively disposed on the side of the first linear guide rail 31, and the input ends of the pair of ball screws 391 are respectively connected to the pair of linear motors 39, and the pair of ball screws 391 are threadedly connected to the pair of first linear slides 32.

[0031] In this embodiment, when the linear motor 39 starts, it drives the ball screw 391 to rotate. Through the threaded engagement between the screw and the first linear slide 32, the rotational motion is converted into the linear movement of the first linear slide 32, thereby realizing the feed control of the rotary motor 35 and the cutting blade 36.

[0032] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
