Description

Technical Field

[0001] This invention relates to the field of band saw blade processing technology, and in particular to a band saw blade guiding mechanism. Background Technology

[0002] Band saw blades come in various specifications, including widths of 13, 19, 27, 34, 41, 54, 67, and 80 mm (eight sizes in total). Due to production line scheduling constraints, a single production line needs to meet the production requirements of multiple band saw blade specifications. Existing band saw blade processing lines, especially the quenching process, are quite long. During operation, the band saw blades must remain vertical and not sway left or right, while also requiring reliable support at the bottom. Therefore, guiding mechanisms are necessary in all band saw blade processing steps to move the blades from one workstation to another.

[0003] Currently, the guide mechanism has a simple structure, cannot be adjusted, and can only be used to guide a single specification of band saw blade. If other models of band saw blades are replaced, the matching guide mechanism must be replaced, which increases the workload of changing models and is time-consuming and labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable and highly versatile band saw blade guiding mechanism.

[0005] The technical solution of the present invention is as follows: a band saw blade guiding mechanism, comprising a base and an adjusting seat, wherein the base is provided with a first rotating support and a second rotating support, which are arranged adjacent to each other in the Y direction; one end of the second rotating support is hinged to the adjusting seat through a first hinge point, and the adjusting seat is hinged to both ends of the base in the Y direction through a second hinge point; the second rotating support can rotate along the first hinge point and move closer to or away from the first rotating support through a first adjusting mechanism provided on its side; both the first and second rotating supports are provided on the adjusting seat, and the pitch angle of the first and second rotating supports along the Y axis is adjusted through the second hinge point, and the adjusting position is limited by a limiting member; both the first and second rotating supports are provided with rollers that rotate relative to each other along the Z axis, and a guide cavity is formed between the two rollers.

[0006] In the above scheme, the structural design of the first hinge point and the second hinge point can realize the adjustment of the rotation, displacement and pitch of the second rotary support installed on the adjustment seat, which can meet the guiding requirements of band saw blades of different sizes and improve versatility.

[0007] In this invention, XYZ constitutes a Cartesian coordinate system.

[0008] Preferably, the first hinge point and the second hinge point have a self-locking function to achieve an adjustment state or a locking state.

[0009] Preferably, both the first and second rotary supports include a support plate, a rotating shaft, spacers, a bearing, and a first cover plate. The lower end of the rotating shaft is fitted onto one end of the support plate, and the upper end of the rotating shaft is fitted with at least two spacers. The bearing is placed between the two spacers, or at the bottom of the two spacers, or at the top of the two spacers. The first cover plate is fixed to the top of the rotating shaft. The inner ring of the bearing is limited by the first cover plate, and the outer ring of the bearing forms the wheel. The support plate of the first rotary support is fixed on the adjusting seat, and the support plate of the second rotary support is connected to the adjusting seat through a first hinge point.

[0010] Preferably, the first hinge point includes a mounting shaft, a second cover plate, and a first locking bolt. The mounting shaft is installed in the support plate of the adjusting seat and the second rotary support. The second cover plate is located on the top of the mounting shaft and contacts the end face of the support plate. The first locking bolt passes through the second cover plate and is threadedly connected to the mounting shaft. When the first locking bolt is tightened, the second cover plate is tightly attached to the support plate to achieve locking.

[0011] Preferably, the first adjusting mechanism includes a first support, a first threaded rod, a second support, a spring, and a handle. The first support is fixed to the adjusting seat. The first threaded rod is threadedly connected to the first support. One end of the first threaded rod is connected to the handle, and the other end is connected to the second support. The second support is connected to a second rotary support. The spring is fitted onto the first threaded rod and abuts against the first and second supports. The first threaded rod extends in the Y direction.

[0012] Preferably, the second hinge point includes a third support and a second locking bolt. The third support is fixed on the base, the adjusting seat is placed beside the third support, and the second locking bolt passes through the third support and is threadedly connected to the adjusting seat.

[0013] Preferably, the limiting member is threadedly connected to the adjusting seat in the Z direction and away from the second hinge point, and the limiting member includes a locking screw for holding the adjusting seat in a horizontal position and an adjusting screw for holding the adjusting seat in an inclined position.

[0014] Preferably, a second adjustment mechanism is provided at one end of the base in the X direction, and a third adjustment mechanism is provided at the other end of the base in the X direction; both the second and third adjustment mechanisms are provided with rollers that can rotate along the Y axis, and the rollers are respectively located on both sides of the guide cavity.

[0015] Preferably, the second adjustment mechanism and the third adjustment mechanism are symmetrically arranged in the X direction.

[0016] Preferably, both the second and third adjusting mechanisms include a fourth support, a rotating plate, a second threaded rod, a fifth support, a connecting shaft, and a third locking bolt. The fourth support is connected to the base, and the rotating plate is mounted on the fourth support by means of the third locking bolt in a rotating or locking manner. One end of the rotating plate is equipped with the roller through the connecting shaft, and the other end of the rotating plate abuts against the second threaded rod. The fifth support is fixed on the fourth support, and the second threaded rod is threadedly connected to the fifth support.

[0017] Compared with related technologies, the beneficial effects of the present invention are as follows:

[0018] 1. The second rotary support in the band saw blade guide mechanism can be adjusted in the X and Y directions by rotating the support plate, thereby increasing the adjustment range;

[0019] 2. The adjusting seat in the band saw blade guiding mechanism realizes the pitch angle adjustment of the first and second rotary supports through the second hinge point, so that the two wheels are in an inclined position. The inclined wheels apply a pressure to the traveling band saw blade to prevent the band saw blade from detaching from the guiding mechanism during operation.

[0020] Third, two rollers are added to the band saw blade guide mechanism to support the bottom of the band saw blade. The rollers are adjusted in the Z direction by rotating on the rotating plate. The rollers and the rotating wheel work together on the band saw blade to keep the band saw blade in a vertical state during operation, ensuring stable and reliable operation.

[0021] Fourth, the adjustment function of the band saw blade guiding mechanism can meet the technical requirements of various band saw blade operations without the need for replacement, thereby improving production efficiency and saving manpower. Attached Figure Description

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" used below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0031] like Figure 1 , Figure 2 As shown, the band saw blade guiding mechanism provided in this embodiment includes a base 1, a first rotating support 2, a second rotating support 3, an adjusting seat 4, a first adjusting mechanism 5, a second adjusting mechanism 6, a third adjusting mechanism 7, a rotating wheel 8, a limiting member 9, a guide cavity 10, a first hinge point 11, a second hinge point 12, and a roller 13.

[0032] The base 1 is provided with a first rotating support 2 and a second rotating support 3, which are arranged adjacent to each other in the Y direction. The adjusting seat 4 is hinged to both ends of the base 1 in the Y direction via a second hinge point 12. The second rotating support 3 moves closer to or away from the first rotating support 2 by rotating along the first hinge point 11 via a first adjusting mechanism 5 provided on its side. Both the first rotating support 2 and the second rotating support 3 are provided on the adjusting seat 4, and the pitch angle of the first rotating support 2 and the second rotating support 3 along the Y axis is adjusted by the second hinge point 12, and the adjustment position is limited by a limiting member 9; both the first rotating support 2 and the second rotating support 3 are provided with a rotating wheel 8 that rotates relative to each other along the Z axis, and a guide cavity 10 is formed between the two rotating wheels 8, through which the band saw blade 100 passes (e.g., Figure 5(As shown).

[0033] like Figure 4 As shown, both the first rotating support 2 and the second rotating support 3 include a support plate 31, a rotating shaft 32, a spacer 33, a bearing 34, and a first cover plate 35. The lower end of the rotating shaft 32 is fitted onto one end of the support plate 31, and the upper end of the rotating shaft 32 is fitted with at least two spacers 33.

[0034] Because the widths of the band saw blades 100 vary, and the roller 8 formed by the bearing 34 needs to be clamped below the tooth grooves when it rolls into contact with the band saw blade 100, this is achieved by adjusting the position between the spacer 33 and the bearing 34. Figure 5 As shown, the bearing 34 is positioned between the two spacers 33, suitable for band saw blades with a width of 27cm-41cm. Figure 6 As shown, the bearing 34 is positioned at the bottom of the two spacers 33, suitable for band saw blades with a width of 13cm-19cm. Figure 7 As shown, the bearing 34 is placed on top of the two spacers 33 and is suitable for band saw blades with a width of 54cm-80cm.

[0035] like Figure 4 As shown, the first cover plate 35 is fixed to the top of the rotating shaft 32 by the fourth locking bolt 36, the inner ring of the bearing 34 is limited by the first cover plate 35, and the outer ring of the bearing 34 forms the rotating wheel 8. Figure 1 As shown, the support plate 31 of the first rotary support 2 is fixed on the adjusting seat 4. Figure 1 , Figure 3 As shown, the support plate 31 of the second rotary support 3 is connected to the adjusting seat 4 through the first hinge point 11.

[0036] like Figure 4 As shown, the first hinge point 11 includes a mounting shaft 111, a second cover plate 112, and a first locking bolt 113. The mounting shaft 111 is installed in the support plate 31 of the adjusting seat 4 and the second rotating support 3. The second cover plate 112 is located on the top of the mounting shaft 111 and contacts the end face of the support plate 31. The first locking bolt 113 passes through the second cover plate 112 and is threadedly connected to the mounting shaft 111. When the first locking bolt 113 is tightened, the second cover plate 112 is tightly attached to the support plate 31 to achieve locking.

[0037] like Figure 1As shown, the first adjusting mechanism 5 includes a first support 51, a first threaded rod 52, a second support 53, a spring 54, and a handle 55. The first support 51 is fixed to the adjusting seat 4. The first threaded rod 52 is threadedly connected to the first support 51. One end of the first threaded rod 52 is connected to the handle 55, and the other end is connected to the second support 53. The second support 53 is connected to the support plate 31 of the second rotary support 3. The spring 54 is fitted onto the first threaded rod 52, and the spring 54 abuts against the first support 51 and the second support 53. The first threaded rod 52 extends in the Y direction.

[0038] like Figure 3 As shown, the second hinge point 12 includes a third support 121 and a second locking bolt 122. The third support 121 is fixed on the base 1, and the adjusting seat 4 is placed beside the third support 121. The second locking bolt 122 passes through the third support 121 and is threadedly connected to the adjusting seat 4. Similarly, when the second locking bolt 122 is tightened, the relative position of the adjusting seat 4 and the third support 121 is fixed.

[0039] like Figure 1 , Figure 2 As shown, the limiting member 9 is threadedly connected to the adjusting seat 4 in the Z direction and away from the second hinge point 12. The limiting member 9 includes a locking screw 91 for holding the adjusting seat 4 in a horizontal position and an adjusting screw 92 for holding the adjusting seat 4 in an inclined position.

[0040] like Figure 1 , Figure 2 , Figure 3 As shown, a second adjustment mechanism 6 is provided at one end of the base 1 in the X direction, and a third adjustment mechanism 7 is provided at the other end of the base 1 in the X direction. The second adjustment mechanism 6 and the third adjustment mechanism 7 are symmetrically arranged in the X direction.

[0041] Both the second adjustment mechanism 6 and the third adjustment mechanism 7 include a fourth support 61, a rotating plate 62, a second threaded rod 63, a fifth support 64, a connecting shaft 65, and a third locking bolt 66. The fourth support 61 is connected to the base 1. The rotating plate 62 is mounted on the fourth support 61 by means of the third locking bolt 66 in a rotating or locking manner. One end of the rotating plate 62 is equipped with the roller 13 through the connecting shaft 65, and the roller 13 rotates along the Y-axis. The other end of the rotating plate 62 abuts against the second threaded rod 63. The fifth support 64 is fixed to the fourth support 61, and the second threaded rod 63 is threadedly connected to the fifth support 64. The end of the second threaded rod 63 is fixedly connected to the rotating plate 62 so that the position of the rotating plate 62 is limited by the threaded connection between the second threaded rod 63 and the fifth support 64. The height of the roller 13 can be adjusted by the spiral extension or retraction of the second threaded rod 63 to accommodate the bottom support of band saw blades 100 of different widths.

[0042] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
