Description

Technical Field

[0001] The invention relates to the technical field of machining, in particular to an automatic production line for sawing profiles. Background Art

[0002] When the profile moves on the sawing machine, it rests against the backing plate to ensure the cutting rules. However, since the profile needs to move and adjust relative to the backing plate, the backing plate is easily worn out after long-term use, resulting in a decrease in the horizontality of the backing plate and affecting the processing accuracy. The backing plate needs to be replaced frequently. Therefore, a sawing machine that can effectively prevent the backing plate from wearing the profile has appeared on the market.

[0003] For example, patent publication number CN219944808U discloses a wear-resistant sawing machine head. The wear-resistant sawing machine head comprises a frame, on which a head is mounted. The head comprises a horizontal worktable and a vertical fixed seat. The worktable is used for left-right movement of feeding. The fixed seat is fixed to the frame, and a sliding plate is mounted on the fixed seat for left-right sliding. By sliding the sliding plate on the fixed seat, relative movement of the profile with respect to the sliding plate is effectively prevented, thereby preventing wear of the profile or the left support plate of the sliding plate.

[0004] The problem with the above technology is that when the profile is sawed by the machine head, it needs to be fixed in position against the left support plate on the sliding plate. When the profile needs to be moved, the sliding plate needs to be moved so that the profile will not wear against the left support plate during the movement. When the profile moves to the corresponding position, the sliding plate will reset and make the left support plate contact with the profile. However, the sliding plate is likely to push the profile when resetting, causing the profile to shift, and the reset sliding plate has high requirements for precision, which is prone to errors.

[0005] Therefore, an automatic production line for sawing profiles is proposed to solve the above technical problems. Summary of the Invention

[0035] The sawing device 3 is provided with a slide rail arranged along the moving direction of the movable seat 33, and the sawing device 3 is also provided with a motor, an air cylinder or an oil cylinder for driving the movable seat 33 to move;

[0036] As reference Figure 11When processing the profile, the feeding device 2 can transport the profile to the sawing device 3, the clamping mechanism 35 can clamp the profile, the bottom of the profile abuts against the base 34, the pressing device 32 presses the end of the profile, and the saw blade 311 cuts the profile by moving the machine head 31 left and right;

[0037] As reference Figure 12 When the profile is cut and needs to be moved backward, the pressing device 32 can loosen the profile, and the driving device 331 drives the base 34 to rotate rightward around the shaft 341 to tilt the profile, so that the profile rotates 32 relative to the pressing device, so that the profile and the pressing device 32 are disengaged, and the profile can be driven to move backward by moving the movable seat 33 backward.

[0057] In a preferred embodiment, as shown in FIG. Figure 7-10 A detection mechanism 44 is provided on the side of the conveyor belt 42.

[0058] When the profile moves to the detection mechanism 44 and the image recognition device identifies that the profile has defects, the lifting platform 411 can rise and lift the profile to separate the profile from the conveyor belt 42. Then the push rod 442 can push the profile on the lifting platform 411 to the material return portion 443, and the profile is discharged to the outside through the material return portion 443. The material return portion 443 is an inclined plate arranged at an angle.

[0062] The first moving part 51 , the second moving part 52 and the clamping head 53 are all driven by a motor, an air cylinder or an oil cylinder.

[0063] Instructions:

[0064] S1, the robotic arm 25 can clamp the profile on the rack 1, place the profile on the feeding part 22, and push the profile to the clamping mechanism 35 through the pushing assembly 26;

[0065] S2. When the profile is located at the clamping mechanism 35, the base 34 is supported by the bottom of the profile, and the right clamping portion 352 can move to the left, so that the left clamping portion 351 and the right clamping portion 352 clamp the profile in the horizontal direction. The upper clamping portion 353 can move downward, so that the upper clamping portion 353 and the base 34 clamp the profile in the vertical direction. Then, the driving device 331 can drive the base 34 to rotate to the right around the shaft 341, thereby driving the profile to tilt. Then, the movable seat 33 can drive the profile to move toward the pressing device 32.

[0066] S3. When the movable seat 33 drives the profile to move to the corresponding position, it stops moving. The driving device 331 can drive the base 34 to rotate leftward around the shaft 341, so that the base 34 is restored to the horizontal position, thereby driving the profile to be restored. At this time, the profile abuts against the left leaning plate 323 and the bottom plate 321. Then the right leaning plate 324 can move leftward, so that the right leaning plate 324 and the left leaning plate 323 press the profile in the horizontal direction. The top plate 322 can move downward, so that the top plate 322 and the bottom plate 321 press the profile in the vertical direction. At this time, the machine head 31 can drive the saw blade 311 to move rightward to cut the profile. The cut profile can be moved to the fixed seat 411.

[0067] S4. After the profile is cut, the machine head 31 can drive the saw blade 311 to move to the left and reset, the right support plate 324 can move to the right and reset, and the top plate 322 can move upward and reset, thereby releasing the profile. Then, the driving device 331 can drive the base 34 to rotate to the right around the shaft 341, thereby driving the profile to tilt, so that the profile is out of contact with the left support plate 323 and the bottom plate 321. Then, the movable seat 33 can drive the profile to continue to move toward the pressing device 32, and continue to repeat steps S3 and S4.

[0068] S5. When the profile is cut to the remaining tailings, the pressing device 32 can press the profile, and then the right clamping portion 352 can be moved to the right and reset, and the upper clamping portion 353 can be moved upward and reset, thereby releasing the tailings, and the driving device 331 can drive the base 34 to move to the left around the shaft 341, so that the base 34 and the left support plate 323 are separated from the contact with the tailings, and then the movable seat 33 can be moved to the initial position, and the driving device 331 can drive the base 34 to move to the right around the shaft 341, so that the base 34 is reset to the horizontal position, and the steps of S1 and S2 are repeated. When the tailings are unloaded, the pressing device 32 can release the tailings and unload them manually or by a robotic arm;

[0069] S6. After receiving the profile, the fixed seat 411 can move to the grinding wheel 412, where the profile is polished by the grinding wheel 412. The profile then passes through the chip blower 43, where the air blowing head 431 removes the iron chips on the profile. The profile then moves to the conveyor belt 42, where it is transported to the detection mechanism 44.

[0070] S7. When the profile moves to the detection mechanism 44, the detection mechanism 44 can detect whether the profile is qualified. When there are defects in the profile, the lifting platform 411 can rise to lift the profile, so that the profile is separated from the conveyor belt 42. Then the push rod 422 can push the fixed profile of the lifting platform 411 to the material return part 443, and the defective profile is discharged to the outside through the material return part 443. Then the push rod 422 and the lifting platform 411 can be reset. When the profile is qualified, it can continue to move along the conveyor belt 42 to the stacking device 5, and the profile is stacked by the stacking device 5.
