Abstract
Description
Technical Field
[0001] This utility model relates to the field of profile or pipe cutting technology, and in particular to an automatic length-fixing mechanism and an automatic length-fixing cutting machine. Background Technology
[0002] In the raw material processing sector, particularly in the metalworking industry, the cutting of common profiles and pipes is a common and crucial process. These materials are typically supplied in long strips, but in practical applications, they often need to be cut into finished products of specific lengths according to design requirements. Therefore, the accuracy and efficiency of the cutting operation are vital for improving the overall production line's capacity and product quality.
[0003] Currently, the common practice for cutting ordinary profiles or pipes is to manually mark the length on the material. Workers typically use a measuring tape or similar tool, hooking it at one end of the material and pulling it along its length to the desired position. They then mark the desired length with a pen or other marking tool. This mark serves as a reference for subsequent cutting operations, ensuring that the finished product meets design requirements.
[0004] Although existing manual marking and cutting methods meet production needs to some extent, they still have the following drawbacks: because marking and cutting are carried out separately, they seriously affect operational efficiency. Utility Model Content
[0005] This application provides an automatic length-fixing mechanism and an automatic length-fixing cutting machine, which solves the technical problem of low work efficiency when cutting profiles or pipes in the prior art.
[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: an automatic length-fixing mechanism, including a mounting frame for placing a cutting machine and a length-fixing bracket fixed to one side of the mounting frame. The extension direction of the length-fixing bracket is perpendicular to the plane where the cutting machine saw blade is located. A movable limiting mechanism is installed on the length-fixing bracket. The movable limiting mechanism includes a movable block that can be fixed to the length-fixing bracket. The movable block is provided with a horizontal slide rail, and a sliding column is installed through the horizontal slide rail. The extension direction of the sliding column is perpendicular to the extension direction of the length-fixing bracket. A corner bracket is fixed to one side of the movable block. The corner bracket is provided with a through hole, and a pull wire passes through the through hole. One end of the pull wire is connected to one end of the sliding column, and the other end of the pull wire can be connected to the handle of the cutting machine. A spring is also connected to the end of the sliding column connected to the pull wire, and the other end of the spring is connected to one side of the movable block. Because a fixed length bracket is fixed on one side of the mounting frame, and a movable block is installed on the fixed length bracket, a sliding column is installed through the movable block, and one end of the sliding column is connected to the handle of the cutting machine through a pull wire, and the sliding column is connected to the movable block through a spring, when using the cutting machine to cut profiles or pipes, the sliding column can abut against the end of the profile or pipe to fix the cutting length, thereby improving cutting efficiency. At the same time, when the handle of the cutting machine is pressed down, the sliding column can move horizontally to facilitate the falling of the profile or pipe after cutting.
[0007] As a further improvement to the above solution, the movable block is nested outside the fixed-length bracket. A threaded hole is provided through one side of the movable block, and a fastening bolt is installed at the threaded hole. The end of the fastening bolt can press against one side of the fixed-length bracket. The movable block is nested outside the fixed-length bracket, which allows the movable block to be flexibly adjusted along its extension direction on the fixed-length bracket, thereby adapting to the cutting needs of profiles or pipes of different lengths. At the same time, the operator only needs to rotate the fastening bolt to fix and release the movable block, making the operation simple and quick.
[0008] As a further improvement to the above solution, the length-fixing bracket is equipped with a scale; thus, the operator can directly determine the cutting length by observing and adjusting the position of the movable block on the scale, further simplifying the operation process.
[0009] As a further improvement to the above solution, the mounting frame includes a rectangular frame formed by welding angle steel, a vertical support is installed on one side of the rectangular frame, the vertical support is perpendicular to the plane on which the rectangular frame is located, and the upper end of the vertical support is provided with a through hole for the pull wire to pass through.
[0010] As a further improvement to the above solution, the pull cable includes a conduit and an inner core that passes through the conduit. The two ends of the conduit are fixed to the inner walls of the through holes on the corner bracket and the vertical bracket, respectively. One end of the inner core is connected to the end of the sliding column, and the other end of the inner core can be connected to the handle of the cutting machine. The two ends of the conduit are firmly fixed to the inner walls of the through holes on the corner bracket and the vertical bracket, ensuring that the pull cable will not shift or fall off during the stretching process.
[0011] This utility model also discloses an automatic length-fixing cutting machine, which adopts the automatic length-fixing mechanism described above.
[0012] As can be seen from the above technical solutions, this utility model has at least the following technical effects or advantages:
[0013] 1. Because a fixed length bracket is fixed on one side of the mounting frame, and a movable block is installed on the fixed length bracket, a sliding column is installed through the movable block, and one end of the sliding column is connected to the handle of the cutting machine through a pull line, and the sliding column is connected to the movable block through a spring, when using the cutting machine to cut profiles or pipes, the sliding column can abut against the end of the profile or pipe to fix the cutting length, which improves the cutting efficiency. At the same time, when the handle of the cutting machine is pressed down, the sliding column can move horizontally to facilitate the falling of the profile or pipe after cutting.
[0014] 2. The movable block is nested outside the fixed-length bracket, allowing it to be flexibly adjusted along its extension direction to adapt to the cutting needs of profiles or pipes of different lengths. At the same time, the operator only needs to rotate the fastening bolt to fix and release the movable block, making the operation simple and quick.
[0015] 3. The fixed-length bracket is equipped with a scale, which allows operators to directly determine the cutting length by observing and adjusting the position of the movable block on the scale, further simplifying the operation process. Attached Figure Description

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0019] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this patent.
[0020] like Figure 1 As shown, this utility model discloses an automatic length-fixing mechanism, which includes a mounting frame 1 for placing a cutting machine and a length-fixing bracket 2 fixed to one side of the mounting frame 1. The extension direction of the length-fixing bracket 2 is perpendicular to the plane where the cutting machine saw blade is located. A movable limiting mechanism is installed on the length-fixing bracket 2 to limit the ordinary profile or pipe to be cut before cutting.
[0021] In this embodiment, the movable limiting mechanism includes a movable block 3, which can be fixed to the fixed-length bracket 2. Furthermore, the movable block 3 can be adjusted relative to the fixed-length bracket 2 within a certain range (e.g., by using fastening bolts 8 to achieve relative fixation). The movable block 3 is provided with a horizontal slide rail, and a sliding column 4 is installed through the horizontal slide rail. The extension direction of the sliding column 4 is perpendicular to the extension direction of the fixed-length bracket 2, and the sliding column 4 can move horizontally within the horizontal slide rail. The sliding column can limit the end of the profile or pipe.
[0022] A corner bracket 5 is fixed to one side of the movable block 3, and the corner bracket 5 has a through hole. A pull wire 6 passes through the through hole, one end of the pull wire 6 is connected to one end of the sliding column 4, and the other end of the pull wire can be connected to the handle of the cutting machine. Specifically in this embodiment, as follows... Figure 1 As shown, the sliding column 4 includes a strip-shaped horizontal plate and a strip-shaped baffle. The baffle is used to limit the end of the profile or pipe. When the end of the profile or pipe abuts against the baffle, the horizontal plate can support the bottom of one end of the profile or pipe. This makes the profile or pipe more stable during the cutting process. Thus, when the handle of the cutting machine is pressed to start the cutting operation, the pull wire 6 will pull the sliding column 4 to move relative to the horizontal slide. When the handle of the cutting machine is pressed to its lowest position, the horizontal plate of the sliding column 4 loses its supporting function for the profile or pipe, so that the cut profile or pipe can fall easily.
[0023] Meanwhile, a spring 7 is also connected to one end of the sliding column 4 that is connected to the pull wire 6, and the other end of the spring 7 is connected to one side of the movable block 3. When the cutting operation is completed, the handle of the cutting machine is lifted, and the spring 7 will pull the sliding column 4 back to its original position on the horizontal slide rail by its tension, thereby resetting the sliding column 4. When cutting again, the reset sliding column can limit the end of the profile or pipe again.
[0024] The movable block 3 can be nested outside the fixed-length bracket 2 and fixed by threaded holes and fastening bolts 8. This allows the operator to adjust the position of the movable block 3 on the fixed-length bracket 2 according to actual needs, thereby changing the position of the limiting point. When the position of the limiting point changes, the cutting length of the profile or pipe changes accordingly. Furthermore, the fixed-length bracket 2 can also be equipped with graduations to allow users to more accurately adjust the position of the limiting point.
[0025] On the other hand, the mounting frame 1 includes a rectangular frame formed by welding angle steel, and a vertical bracket 9 is installed on one side of the rectangular frame. The vertical bracket 9 is perpendicular to the plane of the rectangular frame and is used to support and fix the pull wire 6. The upper end of the vertical bracket 9 is provided with a through hole for the pull wire 6 to pass through, so as to ensure that the pull wire 6 can smoothly pull the slide column 4 for limit adjustment.
[0026] Specifically, the pull wire 6 includes a conduit and an inner core that passes through the conduit. Both ends of the conduit are fixed to the inner walls of the through holes on the corner bracket 5 and the vertical bracket 9, respectively, to protect the inner core from external environmental influences. One end of the inner core is connected to the end of the sliding column 4, and the other end can be connected to the handle of the cutting machine.
[0027] This utility model also discloses an automatic length-fixing cutting machine, which adopts the automatic length-fixing mechanism described above. Before the cutting operation, the operator first needs to adjust the movable limit mechanism so that the movable block 3 is aligned with the corresponding length mark on the length-fixing bracket 2. Then, the movable block is fixed with a locking nut. At this time, the distance between the saw blade and the slide column is the required length, and the cutting operation can be started simply by pressing the cutting handle of the cutting machine.
[0028] During the cutting operation, as the handle of the cutting machine is pressed down, the profile or pipe is cut while the pull wire 6 pulls the slide column 4 horizontally along the horizontal slide, which facilitates the falling of the cut material. After the cutting operation is completed, the handle of the cutting machine is lifted, and the spring 7 pulls the slide column 4 back to its original position on the horizontal slide, so as to limit the end of the profile or pipe for the next cut. In this process, there is no need for manual length marking and measurement, which greatly improves the efficiency and accuracy of the operation.
