Description
Technical Field
[0001] This invention relates to the field of sawing technology, and more specifically, to a multi-angle adjustable guide head for saw blades. Background Technology
[0002] Band saws are indispensable mechanical equipment in machining and industrial production, used to cut workpieces and materials. Band saw blades are the most commonly used type of saw blade on band saws. During the cutting process, band saw blades can deform. To ensure the smoothness of the cut and the cutting effect, the band saw blade needs to be guided to guarantee a smooth cut surface. Currently, commonly used guide heads cannot adjust the guide angle. When the band saw blade is used at an angle, it cannot be guaranteed that the band saw blade will always be in a vertical direction for cutting, resulting in poor cutting effect and a high risk of saw breakage. Summary of the Invention
[0003] To overcome the above shortcomings, the present invention provides a multi-angle adjustable guide head for saw blades, which can adjust the guide angle and guide position, so that the saw blade is always cutting in a vertical direction. Moreover, the guide head is suitable for guiding saw blades of different widths, has good versatility, and ensures the stability of cutting.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multi-angle adjustable guide head for saw blades, including a fixed end plate and a deflection seat, a pressure roller and two oppositely arranged guide rollers are installed on the deflection seat, the saw blade is clamped between the two guide rollers for guidance, and the pressure roller presses on the upper edge of the saw blade; a longitudinal plate and a transverse plate are installed between the fixed end plate and the deflection seat, the longitudinal plate is installed on the fixed end plate and can move longitudinally, the transverse plate is installed on the longitudinal plate and can move laterally, and the deflection seat is installed on the transverse plate and can deflect.
[0005] When a strip saw blade is mounted on saw teeth, the entire oval-shaped blade is tilted. Since the blade needs to be fed perpendicularly to the workpiece or material during cutting, it requires correction and positioning. This application utilizes guide heads to achieve this correction and positioning. Guide heads are installed on both sides of the workpiece or material on the saw teeth, and the blade is clamped between two guide wheels for positioning and guidance. This ensures that the blade at the corresponding point on the workpiece or material is always fed perpendicularly to the workpiece or material, guaranteeing the cutting effect.
[0006] The longitudinal plate can move longitudinally, the transverse plate can move laterally, and the deflector seat can deflect, thereby enabling multi-angle adjustment of the positions of the guide wheel and pressure wheel to ensure that the saw blade can cut perpendicularly. When the saw blade cuts, it receives an upward counterforce, causing the upper edge of the saw blade to contact and position itself with the pressure wheel, ensuring the downward cutting force of the saw blade on the workpiece and material, and guaranteeing the cutting effect.
[0007] The guide head of this patent application can adjust the guide angle and guide position, so that the saw blade is always cutting in a vertical direction. Moreover, the guide head is suitable for guiding saw blades of different widths, has good versatility, and ensures the smoothness of cutting.

[0009] Rotating the longitudinal screw drives the longitudinal push block to move along the longitudinal push groove. The longitudinal inclined block moves synchronously with the longitudinal push block. As the longitudinal inclined block slides along the longitudinal inclined groove, it drives the longitudinal plate to move longitudinally, thereby realizing the longitudinal movement of the deflection seat.
[0010] Preferably, a longitudinal guide structure is installed between the longitudinal moving plate and the fixed end plate. The longitudinal guide structure includes longitudinally arranged longitudinal moving ribs and longitudinal moving grooves, which are slidably connected.
[0011] During the longitudinal movement of the longitudinal plate, the longitudinal convex strip and the longitudinal sliding groove slide against each other to ensure the accuracy of the longitudinal movement of the longitudinal plate and avoid deviation.

The transverse assembly includes a transverse push block driven by a transverse screw, a transverse inclined block is provided on the transverse push block, a transverse inclined groove is provided on the transverse plate, the transverse inclined block and the transverse inclined groove are slidably connected, and a transverse push groove is provided on the longitudinal plate, the transverse push block and the transverse push groove are slidably connected.
[0013] Rotating the transverse screw drives the transverse push block to move along the transverse push groove. The transverse inclined block moves synchronously with the transverse push block. As the transverse inclined block slides along the transverse inclined groove, it drives the transverse plate to move laterally, thereby realizing the transverse movement of the deflection seat.
[0014] Preferably, a transverse guide structure is installed between the transverse plate and the longitudinal plate. The transverse guide structure includes a transverse ridge and a transverse groove that are transversely arranged, and the transverse ridge and the transverse groove are slidably connected.

The deflection assembly includes a deflection push block driven by a deflection screw, a deflection column on the deflection push block, a deflection groove on the deflection seat, the deflection column and the deflection groove being slidably connected, and a deflection push groove on the transverse plate, with the deflection push block and the deflection push groove being slidably connected.
[0017] Rotating the deflection screw drives the deflection push block to move along the deflection push groove. The deflection column moves synchronously with the deflection push block. As the deflection column slides along the deflection inclined groove, it drives the deflection block to rotate and deflect.
[0018] Preferably, a deflection guide structure is installed between the deflection seat and the transverse plate. The deflection guide structure includes an arc-shaped deflection ridge and a deflection groove, which are slidably connected.
[0019] During the deflection process, the deflection cam and the deflection groove slide against each other to ensure the accuracy of the deflection and avoid deviation.
[0020] Preferably, longitudinal locking screws are installed between the longitudinal moving plate and the fixed end plate, transverse locking screws are installed between the transverse moving plate and the longitudinal moving plate, and deflection locking screws are installed between the deflection seat and the transverse moving plate.
[0021] Before longitudinal adjustment, loosen the longitudinal locking screw to allow for longitudinal movement of the longitudinal plate; after longitudinal movement is completed, tighten the longitudinal locking screw to lock and position the longitudinal plate.

[0024] Preferably, the outer wall of the guide wheel is provided with at least two annular grooves.
[0025] During the process of the guide wheel clamping and guiding the saw blade, the annular groove can collect the chips remaining on the surface of the saw blade. Furthermore, the annular groove reduces the contact area between the guide wheel and the saw blade, thus reducing saw blade wear. When the saw blade is wide, the saw teeth on the blade extend downwards beyond the guide wheel. When the saw blade is narrow, the saw teeth on the blade align with the annular groove below, preventing the saw teeth from scratching the outer wall of the guide wheel.
[0026] Preferably, one guide wheel is fixedly mounted on the deflection seat, and a buffer seat that can be moved and adjusted is provided on the deflection seat and the other guide wheel respectively. The other guide wheel is rotatably mounted on the buffer seat, and a buffer spring is installed between the buffer seat and the deflection seat. A lifting seat that can be raised and lowered is provided on the deflection seat, and a pressure wheel is mounted on the lifting seat.
[0027] The buffer seat can be moved and adjusted to change the distance between the two guide wheels, thus accommodating saw blades of different thicknesses for clamping and guiding. A buffer spring is installed between the buffer seat and the deflection seat to allow the guide wheels to move smoothly and prevent the saw blade from getting stuck between the two guide wheels, ensuring the smooth operation of the saw blade.
[0028] Compared with the prior art, the beneficial effects of the present invention are: (1) The guide head of the present patent application can realize the adjustment of the guide angle and the guide position, so that the saw blade is always cutting in the vertical direction.

[0072] The deflector 2 is connected to the auxiliary guide block 10, which has a downward-facing guide groove 11 through which the saw blade 65 passes. A driven wheel 56, driven by the pressure roller 3, is mounted on the auxiliary guide block 10. A transmission belt connects the driven wheel 56 and the pressure roller 3. A driving pulley is mounted on the pressure roller 3, and a driven pulley 57 is mounted on the driven wheel 56. The transmission belt connects the driving pulley and the driven pulley 57. A laterally movable air curtain 58 is mounted on the auxiliary guide block 10, covering the saw blade 65. The air curtain 58 has several air curtain grooves 59 that blow air towards the saw blade 65. A return spring 60 is installed between the air curtain 58 and the auxiliary guide block 10. Several inclined push bars 61 are circumferentially spaced on the end face of the driven wheel 56. A top post 62 is installed on the air curtain 58, resting against the end face of the driven wheel 56 and sliding over the push bars 61. The rotation of the driven wheel 56 causes the push bars 61 to continuously slide over the top post 62, thus achieving the reciprocating movement of the air curtain 58. This causes the air curtain groove 59 to blow air towards the saw blade 65, continuously changing its position to thoroughly clean the chips remaining on the saw blade 65. An isosceles trapezoidal guide rail 63 is installed on the auxiliary guide block 10. A guide groove adapted to the guide rail 63 is installed on the air curtain 58, connecting the air curtain 58 to the guide rail 63 via the guide groove.

A pressure accumulator 64 is provided inside the air curtain 58, and all air curtain slots 59 are connected to the pressure accumulator 64. The pressure accumulator 64 is connected to the high-pressure airflow through a pipe.
[0073] When the strip saw blade 65 is mounted on the saw teeth, the entire oval-shaped saw blade 65 is in an inclined state. Since the saw blade 65 needs to be fed perpendicularly to the workpiece and material direction when cutting, it requires correction and positioning. This application utilizes guide heads to achieve this correction and positioning. Guide heads are installed on both sides of the workpiece or material on the saw teeth, and the saw blade 65 is clamped between two guide wheels 4 for positioning and guidance. This ensures that the saw blade 65 at the corresponding position on the workpiece or material always feeds perpendicularly to the workpiece or material direction, guaranteeing the cutting effect.
[0074] The longitudinal plate 15 can move longitudinally, the transverse plate 16 can move laterally, and the deflector 2 can deflect, thereby enabling multi-angle adjustment of the positions of the guide wheel 4 and the pressure wheel 3 to ensure that the saw blade 65 can cut vertically. When the saw blade 65 cuts, it receives an upward reverse force, causing the upper edge of the saw blade 65 to contact and position with the pressure wheel 3, ensuring that the saw blade 65 exerts a downward cutting force on the workpiece and material, and ensuring the cutting effect.
