Description

Technical Field

[0001] This utility model relates to the field of aluminum profile equipment technology, and in particular to a fixed-length aluminum profile sawing device. Background Technology

[0002] As is well known, in the production process of aluminum profiles, the aluminum profiles need to be cut into the required lengths, and then cold-bent, welded, etc., according to the processing procedures.

[0003] Chinese patent CN222199109U describes a fixed-length sawing machine, including a frame, a conveyor, a trigger, and a saw. The conveyor is mounted on the frame, and the trigger end is slidably mounted on the frame. The trigger works in conjunction with the saw blade of the saw to cut the material. However, in actual use, the following problems still exist:

[0004] During the sawing process of aluminum profiles, the impact force causes damage to the profile cut when the saw blade contacts the aluminum profile. During continuous cutting of the aluminum profile, the friction generates vibration, resulting in an uneven cut surface. When the aluminum profile is cut off, the impact force disappears instantly, causing the saw blade to wobble and damage the aluminum profile cut. Therefore, the existing technology is difficult to maintain the dynamic stability of the saw blade during the entire sawing process, which affects the yield of aluminum profiles.

[0005] Therefore, a fixed-length aluminum profile sawing device is proposed. Utility Model Content

[0010] The stabilizing support includes a spherical slider and an elastic telescopic column. The fixed flange has an annular sliding groove on its side away from the saw blade. The annular sliding groove is close to the edge of the fixed flange, and its central axis is coaxial with the central axis of the fixed flange. The cross-section of the annular sliding groove is arc-shaped. The spherical slider is located in the annular sliding groove and is slidably connected to the fixed flange. One end of the elastic telescopic column is hinged to the spherical slider by a pin, and the other end of the elastic telescopic column is hinged to the outer wall of the bearing ring by a pin. The vibration damping member is connected to the outer wall of the elastic telescopic column.

[0011] The vibration damping component includes a clamp block, a steel strand, and two hammers. The two hammers are respectively connected to both ends of the steel strand.

A second limiting spring 25 is provided in the second hinge groove 23, and the top of the second connecting rod 20 is connected to the inner wall of the second hinge groove 23 through the second limiting spring 25.

[0033] The work process is as follows:

[0034] S1, when starting the equipment, the power assembly 5 is activated, which drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the saw blade 6 to rotate through the fixed flange 7. The pressure spring 11 is in a compressed state, pushing the bearing ring 10 to press the elastic telescopic column 13 towards the saw blade 6. The elastic telescopic column 13 is in a compressed state, and the pressure elastic telescopic column 13 presses the fixed flange 7 through the spherical slider 12. Since the pressure elastic telescopic column 13 and the spherical slider 12 are evenly distributed circumferentially along the central axis of the fixed flange 7, the outward component of the pressing force of the spherical slider 12 on the fixed flange 7 is in a balanced state. The radial component of the pressing force of the spherical slider 12 on the fixed flange 7 increases the friction between the fixed flange 7 and the saw blade 6. At the same time, the annular sliding groove 14 on the fixed flange 7 is close to the edge of the fixed flange 7 and is coaxially set with its central axis. When rotating, the spherical slider 12 rotates around the central axis of the fixed flange 7 in the annular sliding groove 14 relative to the fixed flange 7. This improves the stability of the fixed flange 7 driving the saw blade 6 to rotate when starting the equipment.

[0035] S2, during use, the aluminum profile to be cut is placed on the first conveying mechanism 1 and conveyed to the second conveying mechanism 2. When the aluminum profile reaches a fixed length, the pushing mechanism 3 is activated. The pushing mechanism 3 pushes the adaptive stable sawing component 26 forward. When the saw blade 6 just contacts the aluminum profile, the aluminum profile generates an impact force on the saw blade 6. At this time, the impact force travels along the saw blade 6 through the fixed flange 7 to squeeze the spherical slider 12. The contact surface of the multiple spherical sliders 12 and the fixed flange 7 is squeezed in the opposite direction to the impact force. The pressure spring 11, the elastic telescopic column 13 and the spherical sliders 12 squeeze the fixed flange 7 to generate a reaction force in the opposite direction to the impact force to counteract the impact force. This prevents the impact force generated when the saw blade 6 contacts the aluminum profile from causing the saw blade 6 to wobble and damage the profile cut, thereby improving the yield of the cut aluminum profile.

[0036] S3, during the continuous cutting of aluminum profiles, the side of the saw blade 6 continuously rubs against the aluminum profile, generating vibration. At this time, the vibration is transmitted to the wire clamp block 15 through the saw blade 6, the fixed flange 7, the spherical slider 12 and the elastic telescopic column 13. The wire clamp block 15 converts the vibration into the swing of the hammer head 17 through the steel strand 16 and the hammer head 17, which consumes the vibration energy to suppress the vibration amplitude of the saw blade 6, prevents the vibration generated by the friction between the saw blade 6 and the aluminum profile from causing the vibration amplitude to be too large, resulting in uneven aluminum profile cut surface, and improves the yield of aluminum profile sawing.

[0037] S4, when the saw blade 6 cuts the aluminum profile, the impact force of the aluminum profile on the saw blade 6 disappears instantly, which disrupts the rotational balance of the saw blade 6 and causes the shaft 8 to wobble. The wobble force of the shaft 8 is restricted to one end of the shaft 8 through the bearing bearing 9. The wobble force is converted into the swing of the first pendulum 19 through the bearing ring 10 and the hinged first connecting rod 18. At the same time, the first pendulum 19 causes the second pendulum 21 to swing through the lower hinged second connecting rod 20. In this way, the energy of the wobble is quickly consumed, preventing the instantaneous disappearance of the impact force of the aluminum profile on the saw blade 6 during the sawing process from causing the saw blade 6 to wobble and damage the cut of the aluminum profile, thereby improving the yield of the cut aluminum profile.

[0038] By setting the first hinge groove 22 and the second hinge groove 23, the swing planes of the first pendulum 19 and the second pendulum 21 are orthogonal, achieving decoupling of the two degrees of freedom. This allows for rapid adaptation to the forces generated in all directions of the swing and rapid suppression of the swing. By setting the first limiting spring 24 and the second limiting spring 25, the swing amplitude of the first pendulum 19 and the second pendulum 21 can be limited to avoid collisions with other components. Furthermore, the springs can quickly dissipate the kinetic energy generated by the swing through the hysteresis energy dissipation effect, further preventing the swing. During the fixed-length sawing process, a clamp is needed to limit or translate the aluminum profile. The adaptive stabilizing sawing component 26 is used to make the saw blade 6 and the aluminum profile move synchronously. These are all existing technologies and therefore are not described in detail in the specification.

[0039] The parts of this utility model not described in detail are prior art. Although this utility model has been specifically shown and introduced in conjunction with preferred embodiments, there are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. However, those skilled in the art should understand that various changes in form and detail can be made to this utility model without departing from the spirit and scope of this utility model as defined by the appended claims, and all such changes shall be within the protection scope of this utility model.
