Description

TECHNICAL FIELD

[0001] The application relates to the technical field of profile cutting, and in particular to a cutting device for aluminum profile machining. BACKGROUND

[0002] A profile refers to metal or other materials with certain strength and toughness, and the cross-sectional shape of the profile is various, including I-shaped, circular, U-shaped or some specific contours. In actual application, the profile needs to be cut to meet specific size requirements for subsequent processing operations.

[0003] A cutting device for aluminum profiles is disclosed in the patent application file with the publication number CN119870585A, which comprises a support assembly, a cutting assembly and a fixing assembly. The cutting assembly is arranged inside the support assembly, and the fixing assembly is arranged on the upper part of the support assembly. The fixing assembly is configured to fix the aluminum profile. The support assembly is provided with an operating table and a support mechanism. The operating table is arranged on the upper part of the support mechanism, and the operating table is provided with a cutting groove. The fixing assembly is provided with two fixing mechanisms, which are symmetrically arranged along the cutting groove. The fixing mechanism is provided with a fixing chamber, and the aluminum profile passes through the fixing chamber. The cutting assembly is provided with a cutting knife and a tool bearing mechanism. The cutting knife is connected with the tool bearing mechanism, and the cutting knife is connected with the cutting groove. The tool bearing mechanism is connected with the support mechanism through a transmission assembly. The transmission assembly is configured to drive the tool bearing mechanism to move. The support assembly further comprises two fixing frames, two guide rollers, a plurality of vertical columns and a support bottom frame. The fixing frame and the guide roller are arranged on the operating table. A plurality of vertical columns are arranged between the support bottom frame and the operating table. The support mechanism is connected with the vertical column. During cutting, the fixing chamber provides support for the aluminum profile.

[0004] In the process of profile cutting and machining, clamping and fixing is a key pre-process to ensure the subsequent cutting accuracy. Its core function is to offset the vibration and cutting force generated during cutting through the clamping force of the clamping assembly, so as to ensure that the profile maintains a stable posture during machining.

[0005] However, there are still the following problems in the scheme. When cutting the thin-walled U-shaped profile, due to the thin wall thickness, the rigidity and strength are relatively weak. When clamping the profile through the clamping mechanism, if the clamping force is not properly controlled, two core problems will be directly caused. On the one hand, if the clamping force is increased to pursue stability, the excessive pressure will be concentrated on the weak parts of the profile thin wall and the U-shaped notch, which will easily cause irreversible plastic deformation of the profile, such as notch shrinkage, side wall depression or overall warping, which will not only damage the original size accuracy of the profile, but also may cause the subsequent cutting surface to be inclined, the burr to increase, and even the workpiece to be directly scrapped. On the other hand, if the clamping force is reduced to avoid deformation, a small gap will be generated between the profile and the clamping assembly. During the high-speed rotation cutting process of the cutting tool, the cutting force and vibration will cause the profile to shift and move, resulting in cutting size deviation exceeding the allowable range, which cannot meet the assembly or use requirements.

[0006] In addition, when clamping different specifications of thin-walled U-shaped profiles, the clamping force needs to be adjusted in time, and it is more difficult to control the size of the clamping force, and it is not convenient to cut the thin-walled U-shaped profile and different specifications of thin-walled U-shaped profiles.

DETAILED DESCRIPTION

[0040] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0041] As Figures 1 to 10 shown, the cutting device for aluminum profile machining of the present application comprises a workbench 1, a cutting blade 2, an abutting rod 3 and a pushing piece 4, the U-shaped piece 01 is placed on the workbench 1, the cutter holder of the cutting blade 2 is slidingly arranged on the workbench 1 towards the direction of the U-shaped piece 01, the pushing piece 4 can be arranged as a pneumatic cylinder, the pushing piece 4 is arranged on the workbench 1, a mounting groove 11 is formed on the workbench 1, the abutting rod 3 is arranged in the mounting groove 11 along the direction towards the U-shaped piece 01, and the opening side of the U-shaped piece 01 is placed on the workbench 1, the abutting rod 3 can be moved to abut against the inner side of the U-shaped piece 01 through the opening of the U-shaped piece 01, at the same time, the pushing piece 4 abuts against the outer side of the U-shaped piece 01 to clamp and fix the U-shaped piece 01 through the abutting rod 3, so that the cutting blade 2 can cut the U-shaped piece 01. At the same time, the inner and outer sides of the U-shaped piece 01 are clamped at the same time, which reduces the deformation of the U-shaped piece 01 when it is clamped, and improves the cutting effect of the U-shaped piece 01.

[0042] Referring to Figures 4 to 7A control guide rod 5 is slidably mounted on the abutment rod 3, and the sliding direction of the control guide rod 5 is the same as that of the abutment rod 3. A control component 6 is mounted on the abutment rod 3. A drive component 7 and a drive component 71 are mounted inside the worktable 1. The control component 6 can cooperate with the drive component 7 and the drive component 71 respectively. When the control component 6 cooperates with the drive component 7, it also cooperates with the control guide rod 5. The drive component 7 drives the abutment rod 3 and the control guide rod 5 to move simultaneously through the control component 6. After the control guide rod 5 separates from the control component 6, the control component 6 cooperates with the drive component 71. In the initial state, the end of the control guide rod 5 near the U-shaped part 01 extends to the outside of the abutment rod 3. The drive component 1 7 drives the abutment rod 3 and the control guide rod 5 to move synchronously through the control component 6 until the control guide rod 5 abuts against the inner wall of the U-shaped part 01 and stops moving. The abutment rod 3 continues to move, driving the control guide rod 5 to move relative to the abutment rod 3. The control component 6 separates from the drive component 1 7 and simultaneously cooperates with the drive component 2 71. The drive component 2 71 only drives the abutment rod 3 to move. After the abutment rod 3 abuts against the inner side of the U-shaped part 01, the push component 4 starts synchronously. The push component 4 abuts against the outer side of the U-shaped part 01 to clamp and fix the U-shaped part 01. After the control guide rod 5 stops moving, the second drive component 71 drives the abutment rod 3 to move. When clamping U-shaped parts 01 of different specifications, the distance that the second drive component 71 drives the abutment rod 3 to move is the same. After the abutment rod 3 abuts against the U-shaped part 01, the push component 4 then cooperates with the outside of the U-shaped part 01 to reduce the deformation of the U-shaped part 01, so as to clamp U-shaped parts 01 of different specifications.

[0043] Reference Figures 7 to 10 The control component 6 includes a first rack 61, a second rack 62, and a first spring 63. The first rack 61 and the second rack 62 are connected and are arranged along the sliding direction of the abutment rod 3, and slide in a direction perpendicular to the abutment rod 3. The first rack 61 and the second rack 62 are respectively arranged near the two sides of the abutment rod 3. The first drive component 7 and the second drive component 71 are respectively arranged on the two sides of the abutment rod 3. The first spring 63 can be set as a spring, and the spring is connected to the inside of the first rack 61 and the abutment rod 3 respectively. The first spring 63 is used to drive the first rack 61 to slide in a direction toward the second rack 62. A stop block 611 is provided on the first rack 61, and a clearance groove 51 is opened on the control guide rod 5. The clearance groove 51 is located on the side of the control guide rod 5 near the stop block 611.

[0044] In the initial state, the spring drives the stop 611 to abut against the side of the control guide rod 5. The first toothed rod 61 cooperates with the first drive member 7. The drive member moves the first toothed rod 61 and the abutting rod 3 at the same time. Simultaneously, the control guide rod 5 moves under the action of the stop 611. After the control guide rod 5 abuts against the U-shaped part 01, the control guide rod 5 moves relative to the abutting rod 3. When the clearance groove 51 moves to the stop 611, the first spring member 63 drives the stop 611 to move into the clearance groove 51 and drives the first toothed rod 61 to move and separate from the first drive member 7. At the same time, it drives the second toothed rod 62 to cooperate with the second drive member 71. When the second drive member 71 drives the abutting rod 3 to move, the stop 611 moves in the clearance groove 51, and the control guide rod 5 remains stationary so that the abutting rod 3 can cooperate with the U-shaped part 01 later. In this embodiment, the stop block 611 abuts against the control guide rod 5 to drive the control guide rod 5 to move synchronously with the abutting rod 3. That is, the abutting force applied by the stop block 611 to the control guide rod 5 can only drive the control guide rod 5 to move with the abutting rod 3. This makes it easy for the control guide rod 5 to slide relative to the abutting rod 3 after it abuts against the U-shaped part 01. This allows the control guide rod 5 to play a guiding role when clamping U-shaped parts 01 of different specifications. That is, after the control guide rod 5 stops moving, the distance that the driving member 2 71 drives the abutting rod 3 to move is the same.

[0045] Reference Figures 7 to 10 The first toothed rod 61 and the second toothed rod 62 are spaced apart, and an intermediate rod 612 is provided between the first toothed rod 61 and the second toothed rod 62. The intermediate rod 612 is used to connect the first toothed rod 61 and the second toothed rod 62. The control guide rod 5 is provided between the first toothed rod 61 and the second toothed rod 62. The stop block 611 is provided on the side of the first toothed rod 61 close to the control guide rod 5. By providing the stop block 611 between the first toothed rod 61 and the second toothed rod 62, the stability of the stop block 611 when it engages with the control guide rod 5 is improved.

[0046] Reference Figure 5 and Figure 6 The drive component 7 and drive component 71 have the same structure. Drive component 7 includes a power component 72 and a drive gear 73. The power component 72 can be a motor. The drive gear 73 is located at the output end of the power component 72. The drive gears 73 in drive component 7 and drive component 71 are respectively located on both sides of the abutment rod 3. The two drive gears 73 are used to mesh with the first rack 61 and the second rack 62, respectively. When the first rack 61 meshes with the drive gear 73, the second rack 62 disengages from the corresponding drive gear 73. That is, at the same time, only the first rack 61 or the second rack 62 meshes with the drive gear 73.

[0047] Reference Figure 4 and Figure 5The abutment rod 3 has a groove 31 for placing the control guide rod 5, which slides within the groove 31. A push rod 8 is fixedly installed in the mounting groove 11, and the push rod 8 is positioned along the sliding direction of the abutment rod 3. The end of the push rod 8 extends into the groove 31, and a slope 511 is provided on the side wall of the clearance groove 51 near the push rod 8. After cutting, the second drive component 71 moves the abutment rod 3 to the initial position, while the push rod 8 moves relative to the groove 31 within the groove 31 until the end of the push rod 8 abuts against the control guide rod 5. The push rod 8 then moves the control guide rod 5 relative to the abutment rod 3, causing different positions on the slope 511 to abut against the stop block 611. This causes the stop block 611 to move and abut against the side of the control guide rod 5, while simultaneously engaging the first gear 61 with the drive gear 73. The first drive component 7 then moves the abutment rod 3 and the control guide rod 5 to the initial position to clamp the U-shaped piece 01 again.

[0048] Reference Figures 1 to 4 Two sets of pushers 4 and abutment rods 3 are provided on both sides of the cutting blade 2, and the two sets of pushers 4 are arranged along the length direction of the U-shaped part 01. Each set of multiple pushers 4 and abutment rods 3 is set as a group. Multiple abutment rods 3 correspond to multiple side walls of the U-shaped part 01 respectively. Multiple pushers 4 are also arranged at intervals around the U-shaped part 01. In this embodiment, three abutment rods 3 are set as a group, and the three abutment rods 3 correspond to three side walls of the U-shaped part 01 respectively. By clamping multiple positions on the U-shaped part 01, the stability of the U-shaped part 01 is improved.

[0049] Reference Figure 5 and Figure 6 The two adjacent abutment rods 3 are arranged at an included angle. Multiple drive gears 73 and multiple abutment rods 3 are correspondingly arranged. A first gear 731 is arranged between every two adjacent drive gears 73, and the first gear 731 is rotatably arranged within the mounting groove 11. A second gear 732 is coaxially arranged on the drive gear 73. The first gear 731 simultaneously meshes with the second gear 732 on two adjacent drive gears 73. This allows the multiple drive gears 73 to rotate synchronously in the same direction. In the initial state, the power component 72 simultaneously drives multiple first racks 61 to move, which in turn drives multiple control guide rods 5 to move. After the multiple control guide rods 5 successively abut against the inner side of the U-shaped part 01, all the first racks 61 separate from the drive gear 73. At this time, all the second racks 62 mesh with the drive gear 73 in the second drive component 71. Then, the second drive component 71 drives the abutting rod 3 to move. At this time, the abutting rod 3 moves the same distance as the U-shaped part 01 when it abuts. It is only necessary to control the power component 72 in the second drive component 71 to drive the second rack 62 to move the corresponding distance each time, so as to quickly clamp and fix the U-shaped part 01.

[0050] Reference Figures 5 to 6In order to improve the clamping effect of the abutment rod 3 on the U-shaped part 01, a top block 9 is provided at one end of the abutment rod 3 near the U-shaped part 01. The top block 9 is arranged along the arrangement direction of the multiple abutment rods 3, that is, the top blocks 9 on the multiple abutment rods 3 are arranged in the same plane. The abutment rod 3 cooperates with the U-shaped part 01 through the top block 9. At the same time, after the top block 9 cooperates with the U-shaped part 01, the U-shaped part 01 is subjected to uniform force, which improves the stability of the U-shaped part 01 when it is clamped.

[0051] Reference Figures 4 to 6 A through slot 91 is provided on the top block 9, penetrating the top block 9. The control guide rod 5 passes through the through slot 91 and is spaced apart from the inner wall of the through slot 91. A second spring 92 is provided on the abutment rod 3. The second spring 92 can be a spring. The end of the spring away from the abutment rod 3 is connected to the top block 9. By providing the spring, after the pusher 4 abuts against the U-shaped part 01, the abutment rod 3 can be moved again, compressing the second spring 92 and improving the clamping effect on the U-shaped part 01. In addition, the side of the top block 9 near the U-shaped part 01 is arc-shaped, and the arc side of the top block 9 abuts against the inner wall of the U-shaped part 01, so that the top block 9 at different positions can cooperate with the U-shaped part 01 to fix the U-shaped part 01.

[0052] The implementation principle of this invention is as follows: In the initial state preparation, when the device is in the initial position, the abutment rod 3 and the control guide rod 5 remain relatively stationary. The end of the control guide rod 5 near the U-shaped part 01 extends to the outside of the abutment rod 3. In the control member 6, the first toothed rod 61 meshes with the drive gear 73 of the drive member 7 under the action of the first spring 63, while the second toothed rod 62 is in a disengaged state from the drive gear 73 of the drive member 71. The pusher 4 is in a retracted state, the blade holder of the cutting blade 2 is located in the initial position away from the U-shaped part 01, and the mounting groove 11 on the worktable 1 provides space for the movement of each component.

[0053] Then, the U-shaped part 01 is placed on the workbench 1 with its open side facing down, so that its inner sidewall aligns with the moving direction of the abutment rod 3 and the control guide rod 5. The power component 72 of the drive component 7 is activated, driving the gear 73 to rotate and move the first rack 61. Since the stop block 611 on the first rack 61 is in contact with the side of the control guide rod 5 at this time, the control guide rod 5 moves synchronously towards the U-shaped part 01 along with the abutment rod 3. During this process, multiple abutment rods 3 move synchronously under the meshing transmission of the first gear 731 and the second gear 732, ensuring that the control guide rod 5 simultaneously approaches different inner sidewalls of the U-shaped part 01.

[0054] When the end of the control guide rod 5 abuts against the inner wall of the U-shaped part 01, the control guide rod 5 stops moving, while the abutting rod 3 continues to move under the action of the drive member 7, causing the control guide rod 5 to slide relative to the groove 31 of the abutting rod 3. As the control guide rod 5 moves, the clearance groove 51 on it gradually aligns with the stop block 611, the first spring member 63 releases its elastic force, pushing the first toothed rod 61 to slide towards the second toothed rod 62, so that the stop block 611 is engaged in the clearance groove 51. At the same time, the first toothed rod 61 separates from the drive gear 73 of the drive member 7, and the second toothed rod 62 moves synchronously and meshes with the drive gear 73 of the drive member 71, completing the switching of the power source from the drive member 7 to the drive member 71.

[0055] Subsequently, the second drive unit 71 is activated, and its drive gear 73 drives the second rack 62 to move, which in turn drives the abutment rod 3 to continue moving towards the U-shaped part 01. At this time, the control guide rod 5 remains stationary because the stop block 611 slides in the relief groove 51. Since multiple abutment rods 3 move synchronously through gear linkage, and the travel distance set by the second drive unit 71 is fixed, the top block 9 at the end of the abutment rod 3 finally makes precise contact with the inner wall of the U-shaped part 01. The arc-shaped design of the top block 9 adapts to the inner wall curvature of U-shaped parts of different specifications, and the second spring 92 is compressed to generate pre-tightening force to ensure stable contact.

[0056] After the abutment rod 3 completes its inner abutment, the pusher 4 starts simultaneously, and its output end moves towards the outer wall of the U-shaped part 01, forming a combined internal and external clamping force with the abutment rod 3. The two sets of pushers 4 and abutment rods 3 are arranged along the length of the U-shaped part, and multiple clamping points are evenly distributed to avoid deformation of the U-shaped part due to excessive local stress and to ensure the structural stability of the cutting position.

[0057] After the U-shaped part 01 is securely clamped, the blade holder of the cutting blade 2 slides along the worktable 1 to cut the U-shaped part. After cutting, the pusher 4 retracts and resets, and the drive component 2 71 drives the abutment rod 3 to move in the opposite direction to the initial position. During this process, the pusher 8 in the mounting groove 11 moves relative to the slide groove 31, and its end abuts against the control guide rod 5, pushing the control guide rod 5 to slide in the opposite direction. The inclined surface 511 of the control guide rod 5 presses against the stop block 611, so that the first toothed rod 61 overcomes the elastic force of the first spring 63 and resets, re-engaging with the drive gear 73 of the drive component 1 7. The control guide rod 5 also returns to the initial position with the abutment rod 3, preparing for the next cutting cycle.

[0058] After the control guide rod 5 abuts against the inner side of the U-shaped part 01, the first spring 63 drives the first toothed rod 61 to separate from the drive gear 73. At the same time, the second toothed rod 62 meshes with the drive gear 73 in the second drive member 71. After the first toothed rod 61 in multiple abutting rods 3 has separated from the drive gear 73, the second drive member 71 drives the abutting rod 3 to move to abut against the inner side of the U-shaped part 01. Then, the pusher 4 is activated. The output end of the pusher 4 cooperates with the abutting rod 3 to clamp the U-shaped part 01. The control guide rod 5 is set to clamp U-shaped parts 01 of different specifications. At the same time, before the pusher 4 is activated, the abutting rod 3 is moved to cooperate with the inner side of the U-shaped part 01 to reduce the deformation of the U-shaped part 01 when it is clamped, so as to cut the U-shaped part 01 and U-shaped parts 01 of different specifications.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
