[0002] A band saw is a commonly used metal processing equipment. Its working principle is to use a ring-shaped band saw blade to cut at high speed. During the high-speed operation of the band saw blade, its stability and cutting accuracy are directly affected by the guiding device. The function of the guiding device is to support and guide the band saw blade, prevent the saw blade from twisting or swaying, and ensure the smoothness of the cutting process and the accuracy of the cutting section.

[0003] The existing band saw blade guide block is in direct contact with the high-speed moving band saw blade, and is subjected to huge friction and cutting forces. Long-term use will lead to wear of the guide components, especially the guide surface in contact with the saw blade. Wear of the guide components will directly affect the guiding accuracy and effect, and in severe cases, it may cause the saw blade to deviate or even break, affecting the normal operation of the equipment and the processing quality.

[0004] Therefore, it is necessary to provide a new band saw blade guiding device to solve the above-mentioned technical problems. Utility Model Content

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0017] Please see Figures 1 to 2 The present invention provides a band saw blade guiding device, which includes: a fixed plate 1, a movable guide arm 4, a guide seat 5, a guide block 8, an adjusting block 9, and a pad replacement mechanism.

[0018] The upper side wall of the movable guide arm 4 is provided with an adjustment groove 3. The fixing plate 1 passes through the adjustment groove 3 and is slidably connected to it. A locking block 2 is threadedly connected to the outer side of the movable guide arm 4. The inner end face of the locking block 2 penetrates the side wall of the movable guide arm 4 and is rotatably connected to the inner end face of the adjustment groove 3. The bottom end of the movable guide arm 4 is fixedly connected to a guide seat 5 by bolts. The side wall of the guide seat 5 is provided with a guide groove 6. Two opposing guide blocks 8 are provided in the guide groove 6. Two adjustment blocks 9 are threadedly connected to both sides of the guide seat 5. The inner end face of the adjustment block 9 penetrates the side wall of the guide seat 5 and is rotatably connected to the corresponding guide block 8. The inner end face of the guide block 8 is provided with a liner replacement mechanism. The gasket replacement mechanism includes a guide gasket 12 and a clamping block 13. The inner end face of the guide block 8 is provided with a replacement groove 15, and the guide gasket 12 is slidably connected in the replacement groove 15. The inner end face of the guide gasket 12 is fixedly connected with two symmetrically distributed clamping blocks 13. The inner end face of the guide block 8 is provided with a sliding groove that cooperates with the clamping block 13. The clamping block 13 is slidably connected to the sliding groove. The front and rear end faces of the guide block 8 are threaded with detachable mounting blocks 16. The inner end face of the mounting block 16 contacts the clamping block 13. The middle part of the replacement groove 15 is provided with a through groove 14 for adding cooling liquid. The guide gasket 12 is made of engineering plastic filled with polytetrafluoroethylene.

[0019] It should be noted that the sliding connection between the adjustment groove 3 on the upper side wall of the movable guide arm 4 and the fixed plate 1 enables the position adjustment of the guide device along the direction of the fixed plate 1. With the locking block 2 threaded on the outer side of the movable guide arm 4, its inner end face penetrates the side wall of the movable guide arm 4 and is rotatably connected to the inner end face of the adjustment groove 3. Tightening the locking block 2 can lock the position of the movable guide arm 4, thereby conveniently and quickly adjusting the overall position of the guide device to adapt to different cutting environments.

[0020] The guide seat 5 is fixed to the bottom of the movable guide arm 4 by bolts. Two opposing guide blocks 8 are provided in the guide groove 6 on its side wall for the main guidance of the saw blade. By rotating the adjusting block 9 which is threaded to both sides of the guide seat 5, the inner end face of which is rotatably connected to the corresponding guide block 8, the distance between the guide blocks 8 can be precisely adjusted to achieve fine adjustment of the guide gap of the saw blade and ensure high-precision guidance.

[0021] Secondly, the guide pad 12 of this device is extremely easy to replace. The guide block 8 has a replacement groove 15 on its inner end face, and the guide pad 12 is slidably connected therein. The clamping block 13 fixedly connected to the inner end face of the guide pad 12 slides and engages with the sliding groove on the inner end face of the guide block 8 to form a reliable sliding structure. When the guide pad 12 is worn, there is no need for complicated disassembly. Just unscrew the detachable mounting blocks 16 on the front and rear end faces of the guide block 8, and you can directly pull out the old pad along the replacement groove 15 and quickly install the new guide pad 12. Then use the mounting blocks 16 to lock it in place, reducing downtime for maintenance.

[0022] Furthermore, to improve the guiding effect and service life, a through groove 14 is provided in the middle of the replacement groove 15, which facilitates the direct addition of cooling fluid to the contact area between the guide pad 12 and the saw blade, effectively dissipating frictional heat and reducing wear. At the same time, the guide pad 12 is made of engineering plastic filled with polytetrafluoroethylene, which has low friction and high wear resistance, further improving the guiding performance and durability of the device. A pre-guide plate 11 is fixedly connected to the outer side of the guide seat 5. Two pre-guide wheels 10 are fixedly connected to the lower surface of the pre-guide plate 11, and an upper guide wheel 7 is fixedly connected between the inner walls of both sides of the guide groove 6.

[0023] It should be noted that the pre-guide plate 11 fixedly connected to the outer side of the guide seat 5 and the two pre-guide wheels 10 below it are located before the saw blade enters the main guide block 8, and provide initial guidance and stabilization for the saw blade. At the same time, upper guide wheels 7 are fixedly connected between the inner walls on both sides of the guide groove 6 to provide support for the upper end face of the band saw blade. These auxiliary guide wheels work together to enhance the running stability of the band saw blade.

[0024] In summary, the band saw blade guiding device provided by this utility model embodiment includes components such as a fixed plate 1, a movable guide arm 4, and a guide seat 5. The movable guide arm 4 is slidably connected to the fixed plate 1 through an adjustment groove 3, and with the help of a locking block 2, the device position can be quickly adjusted to adapt to different cutting environments. The guide seat 5 is provided with a guide block 8, and the guide gap can be precisely adjusted by an adjustment block 9 to ensure high-precision guidance. The inner end face of the guide block 8 is provided with a pad replacement mechanism. The guide pad 12 is engaged with the sliding groove of the replacement groove 15 through a clamping block 13 and fixed with a mounting block 16, realizing convenient and efficient replacement of the guide pad 12 and reducing maintenance time. The through groove 14 of the replacement groove 15 facilitates the addition of cooling fluid. Combined with the wear-resistant material of the guide pad 12, it effectively reduces wear and extends service life. In addition, the pre-guide plate 11, the pre-guide wheel 10, and the upper guide wheel 7 provide auxiliary guidance and support, enhance operational stability, and improve sawing efficiency and quality.
