Description

Technical Field

[0001] This utility model relates to the field of metal heat treatment technology, and in particular to a saw blade tempering tensioning guide fixture. Background Technology

[0002] A saw blade is a widely used tool in metal cutting, typically made of high-strength alloy steel, and features continuously arranged toothed cutting edges. In practical use, saw blades need to possess good hardness, toughness, and wear resistance to ensure cutting efficiency and service life. To achieve these performance requirements, saw blades must undergo a heat treatment process during manufacturing, with tempering being a key step. Tempering, by controlling the heating temperature and cooling rate, allows the saw blade to achieve an appropriate balance of hardness and toughness, while simultaneously eliminating internal stress and preventing breakage or deformation during use.

[0003] Utility model patent CN 208121136 U discloses a tensioning guide fixture for a saw blade tempering device, comprising a strip-shaped base plate, mounting base plates fixed at both ends of the base plate, mounting holes formed at both ends of the mounting base plates, and several guide wheels fixed in the middle of the base plate. Each guide wheel includes a hinge seat, and rollers are hinged to the hinge seat via hinge shafts. Tensioning seats are fixed at both ends of the base plate, and each tensioning seat includes a base. Two opposing smooth slide plates are inserted into the base. T-shaped guide posts are inserted into the upper and lower ends of the base. The ends of the guide posts are fixed to the smooth plate. Insertion holes are formed on the base between the guide posts. An external threaded sleeve opposite to the insertion hole is fixed on the outer wall of the base. An adjusting cap is screwed onto the external threaded sleeve. A support shaft is inserted into the adjusting cap and fixed to the smooth plate. A compression spring is inserted into the support shaft, with one end of the compression spring pressing against the smooth plate and the other end pressing against the adjusting cap. This device can guide and tension both ends of the saw blade to a certain extent, reducing the chance of the saw blade colliding with the heating high-frequency tube.

[0004] However, there are still prominent problems in practical applications: there is a certain gap between the rollers in the device. During the operation of the saw blade, due to its own gravity, the saw blade is prone to bending downwards or even partially losing support at the gap between the rollers, which causes the saw blade to "lift" during operation, affecting the stability of the guide and the uniformity of tempering.

[0005] Therefore, to address the shortcomings of existing technologies, we urgently need a saw blade tempering tensioning guide fixture to solve this problem. This fixture should significantly improve the stability of the guide and the uniformity of tension, while better meeting the demands of modern high-precision and high-efficiency production, providing strong support for the sustainable development of the saw blade processing industry. Utility Model Content

[0006] The purpose of this invention is to provide a saw blade tempering tensioning guide fixture, which solves the problem in the prior art where there is a certain gap between several rollers. During the operation of the saw blade, due to its own weight, the saw blade is prone to bending downwards or even partially losing support at the gap between the rollers, resulting in the saw blade tilting up during operation, which affects the stability of the guide and the uniformity of tempering.

[0007] To achieve the above objectives, this utility model provides a saw blade tempering tensioning guide fixture, including a guide table and a mounting frame disposed at the top center of the guide table. Several guide rollers are rotatably connected inside the mounting frame, and a guide belt that is wound and cooperates with the several guide rollers is disposed at the top of the mounting frame.

[0008] Two mounting plates are provided on both sides of the top of the guide platform. Both mounting plates are connected to the top of the guide platform through a support structure. A limit plate is provided on the side of the two mounting plates that are close to each other. The limit plate is connected to the mounting plate through a horizontal pushing structure.

[0009] The mounting plate is made of metal, and the length of the limiting plate is greater than the length of the mounting plate.

[0010] The bottom of the mounting bracket is bolted to the top of the guide platform. The supporting structure includes a connecting bracket, one end of which is connected to the mounting plate and the other end of which is connected to the top of the guide platform.

[0011] The horizontal pushing structure includes an adjusting screw rotatably connected to one side of the limiting plate, with one end of the adjusting screw threaded through the mounting plate.

[0012] The guide platform has fixed rods bolted to both sides of its top, and the two ends of the fixed rods are respectively connected to the adjacent connecting brackets.

[0013] The adjusting screw has guide rods on both sides of its bottom. One end of the guide rod is connected to the limiting plate, and the other end slides through the mounting plate. The adjusting screw has a compression spring on its top. One end of the compression spring is connected to the limiting plate, and the other end is connected to the mounting plate.

[0014] This utility model discloses a saw blade tempering tensioning guide fixture. By setting multiple guide rollers in the mounting frame and using them in conjunction with a guide belt, it effectively eliminates the gap problem between traditional rollers, avoids the saw blade sagging and "head lifting" phenomenon caused by gravity during operation, significantly improves the stability of guidance, ensures uniform heating of the saw blade in the high-frequency heating tube, and thus improves the tempering quality. Secondly, the traction method of the guide belt is more continuous and stable than the traditional spring tensioning structure, reducing the impact of tension fluctuations on the saw blade, helping to improve the uniformity of tension during tempering, and reducing the risk of saw blade breakage or jamming. Thirdly, by setting an adjustable limit plate and a horizontal pushing structure, it effectively constrains the saw blade's running path, preventing lateral deviation during high-speed operation, further improving guidance accuracy and safety.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention. Example

[0023] Please see Figure 1-5As shown, a saw blade tempering tensioning guide fixture of this embodiment includes a guide table 1 and a mounting frame 3 set at the top center of the guide table 1. Support frames 2 are connected to both sides of the bottom of the guide table 1. Several guide rollers 13 are rotatably connected inside the mounting frame 3. A guide belt 12 that is wound and cooperates with several guide rollers 13 is provided on the top of the mounting frame 3.

[0024] Two mounting plates 5 are provided on both sides of the top of the guide platform 1. Both mounting plates 5 are connected to the top of the guide platform 1 through a support structure. A limit plate 6 is provided on the side of the two mounting plates 5 that is close to each other. The limit plate 6 is connected to the mounting plate 5 through a horizontal pushing structure.

[0025] First, the fixture is installed in a suitable position on the tempering equipment. The guide table 1 serves as the basic support structure for the entire device. A mounting frame 3 is fixedly installed at the center of its top. Several guide rollers 13 are rotatably connected inside the mounting frame 3. These guide rollers 13 are evenly arranged along the saw blade's running direction and are connected to the guide belt 12 by a winding mechanism. The guide belt 12 is driven to rotate by a drive mechanism, which drives the guide rollers 13 to rotate synchronously during operation, thereby achieving continuous traction and stable conveying of the saw blade. At the same time, two mounting plates 5 are fixed on the top of each side of the guide table 1. The mounting plates 5 are connected to the guide table 1 through a support structure to ensure the stability and rigidity of the overall structure. Each mounting plate 5 has an adjustable limiting plate 6 on one side. The limiting plate 6 is connected to the mounting plate 5 through a horizontal pushing structure, and its lateral position can be adjusted according to the saw blade of different width specifications, thereby achieving lateral limiting of the saw blade during operation and preventing it from deviating or tilting. When the saw blade passes through the guide fixture, the guide roller 13 provides continuous support, avoiding the saw blade sagging caused by the gap between traditional rollers, while the guide belt 12 plays an auxiliary traction and tensioning role, further improving the smoothness of the saw blade operation. In addition, the adjustable design of the limiting plate 6 also enables the device to adapt to various specifications of saw blades, improving its versatility and applicability. Example

[0026] Please see Figure 1-5 As shown in the figure, in this embodiment of a saw blade tempering tensioning guide fixture, the mounting plate 5 is made of metal, and the length of the limiting plate 6 is greater than the length of the mounting plate 5. Specifically, by making the mounting plate 5 of metal and setting the length of the limiting plate 6 to be greater than the length of the mounting plate 5, it is ensured that the mounting plate 5 has sufficient strength and rigidity to support the entire fixture structure. At the same time, the longer limiting plate 6 can provide a wider range of lateral restraint to accommodate saw blades of different widths, thereby achieving the effect of enhancing the overall structural stability and improving the versatility of the equipment.

[0027] The horizontal pushing structure includes an adjusting screw 9 rotatably connected to one side of the limiting plate 6. One end of the adjusting screw 9 is threaded through the mounting plate 5. Specifically, by including the adjusting screw 9 rotatably connected to one side of the limiting plate 6 and having one end threaded through the mounting plate 5, the operator can rotate the adjusting screw 9 as needed to precisely adjust the position of the limiting plate 6 to accommodate saw blades of different specifications. This design makes adjusting the position of the limiting plate 6 simple and quick, without the need for complex tools or lengthy adjustments, thus improving work efficiency and flexibility.

[0028] Guide rods 11 are provided on both sides of the bottom of the adjusting screw 9. One end of the guide rod 11 is connected to the limiting plate 6, and the other end slides through the mounting plate 5. A compression spring 10 is provided on the top of the adjusting screw 9. One end of the compression spring 10 is connected to the limiting plate 6, and the other end is connected to the mounting plate 5. Specifically, by providing guide rods 11 on both sides of the bottom of the adjusting screw 9, with one end connected to the limiting plate 6 and the other end sliding through the mounting plate 5, and by providing compression spring 10 on the top of the adjusting screw 9, with one end connected to the limiting plate 6 and the other end connected to the mounting plate 5, the guide rods 11 provide additional support for the limiting plate 6, ensuring its straightness during movement. The compression spring 10 can absorb vibration to a certain extent, reducing the impact on the limiting plate 6, thereby further improving the accuracy and stability of the limiting plate 6's movement. At the same time, this also reduces errors caused by mechanical wear and extends the service life of the equipment. Example

[0029] Please see Figure 1-5 As shown, this embodiment of a saw blade tempering tensioning guide fixture has a mounting frame 3 bolted to the top of the guide platform 1. The supporting structure includes a connecting bracket 4, one end of which is connected to the mounting plate 5, and the other end to the top of the guide platform 1. Specifically, the bolted connection between the bottom of the mounting frame 3 and the top of the guide platform 1, along with the connecting bracket 4 in the supporting structure, allows for adjustment of the mounting frame 3's positional accuracy during installation. Furthermore, the connecting bracket 4 enhances the overall stability of the device. This design not only simplifies the assembly process but also makes maintenance more convenient, ultimately improving the fixture's structural stability and ease of maintenance.

[0030] Both sides of the top of the guide table 1 are bolted with fixing rods 8. The two ends of each fixing rod 8 are connected to adjacent connecting brackets 4. Specifically, this bolted connection of fixing rods 8 to both sides of the top of the guide table 1, with each end of the fixing rod 8 connected to an adjacent connecting bracket 4, strengthens the connection between the guide table 1 and the connecting brackets 4, improving the rigidity and stability of the entire device. This helps prevent structural deformation caused by vibration or other external forces, ensuring the smooth operation of the saw blade and increasing the equipment's service life and reliability.

[0031] This solution includes the following work process:

[0032] First, the entire fixture is installed in the appropriate position on the tempering equipment via the guide table 1. As a basic support structure, the guide table 1 bears all the upper components and provides a stable installation platform for the entire assembly. A mounting frame 3 is fixedly installed at the center of the top of the guide table 1. The bottom of the mounting frame 3 is connected to the guide table 1 via bolts, facilitating installation, adjustment, and subsequent maintenance. Several guide rollers 13 are rotatably connected inside the mounting frame 3. These guide rollers 13 are evenly arranged along the saw blade's running direction to provide continuous support for the saw blade, avoiding the problem of saw blade sagging caused by gaps between traditional rollers. Simultaneously, a guide belt 12 is wound around the outside of multiple guide rollers 13 and driven to rotate by a drive mechanism. During operation, it drives the guide rollers 13 to rotate synchronously, thereby achieving continuous traction and stable conveying of the saw blade and effectively improving the uniformity of tension. Two mounting plates 5 are fixed to the top of each side of the guide table 1. The mounting plates 5 are made of metal, possessing good strength and rigidity. They are connected to the guide table 1 via a support structure, which includes a connecting bracket 4. One end of the connecting bracket 4 is connected to the mounting plate 5, and the other end is connected to the guide table. 1. The top is fixed, further enhancing the stability of the overall structure. Each mounting plate 5 has an adjustable limiting plate 6 on one side. The limiting plate 6 is longer than the mounting plate 5, covering a wider range to accommodate saw blades of different widths. The limiting plate 6 is connected to the mounting plate 5 via a horizontal pushing structure, which includes an adjusting screw 9, a guide rod 11, and a compression spring 10. The adjusting screw 9 is rotatably connected to one side of the limiting plate 6 and threaded through the mounting plate 5. The operator can precisely control the position of the limiting plate 6 by rotating the adjusting screw 9. At the same time, the guide rod 11 is set on both sides of the bottom of the adjusting screw 9. One end is connected to the limiting plate 6, and the other end slides through the mounting plate 5 to ensure the straightness and stability of the limiting plate 6 during movement. The compression spring 10 is set on the top of the adjusting screw 9. One end is connected to the limiting plate 6, and the other end is connected to the mounting plate 5. It can absorb vibration to a certain extent and reduce displacement errors caused by impact. In addition, there are also fixing rods 8 on both sides of the top of the guide table 1. The two ends of the fixing rods 8 are connected to the adjacent connecting brackets 4, which strengthen the structural connection strength and improve the overall rigidity.

[0033] The saw blade tempering tensioning guide fixture provided by this utility model has the following detailed and significant beneficial effects: First, through the cooperative design of the guide roller 13 and the guide belt 12, the technical problem of saw blade sagging and unstable operation caused by excessively large roller spacing in traditional methods is solved. The guide roller 13 is continuously distributed, providing full-process support, while the guide belt 12 assists in traction, improving the stability and heat uniformity of the saw blade operation, thereby improving the tempering quality. Second, the horizontal pushing structure composed of the limiting plate 6, adjusting screw 9, guide rod 11, and compression spring 10 effectively restricts the saw blade's running path, preventing lateral deviation or tilting. The adjusting screw 9 makes the adjustment of the limiting plate 6 more precise and convenient, the guide rod 11 ensures the straightness of the limiting plate 6 during movement, and the compression spring 10 plays a crucial role in... The device provides buffering and shock absorption, improving guiding accuracy and stability. Furthermore, the metal construction of the mounting plate 5 and the longer length of the limiting plate 6 not only enhances structural strength but also expands its applicability, allowing the device to accommodate various saw blade specifications and improving versatility and flexibility. Additionally, the connection method between the connecting bracket 4 and the mounting plate 5 and the guide table 1, as well as the connection structure between the fixing rod 8 and the connecting bracket 4, all enhance the overall stability and vibration resistance of the device, preventing structural deformation caused by external vibration or load changes, thereby extending the equipment's service life. Finally, the bolted connection between the mounting frame 3 and the guide table 1, and the adjustable structure between the adjusting screw 9 and the limiting plate 6, simplify assembly and maintenance processes, reduce operating costs, and improve production efficiency.
