The chamfering buffer area is equipped with conveyor rollers in two directions. One conveyor roller is set along the production line direction to receive strips from the strip feeding area, while the other conveyor roller buffer uses a magnetic attraction mechanism to separate the strips and then transport them to the slag cleaning and chamfering area. The slag removal and chamfering area is equipped with a feeding roller conveyor, a grinding and slag removal machine, a chamfering machine, and a discharge roller conveyor. The feeding roller conveyor feeds the strip material, while the grinding and slag removal machine and the chamfering machine grind and chamfer the four corners of the strip panel. The discharge roller conveyor transports the strip material to the cutting buffer area. A profile feeding area is located on the side of the slag removal and chamfering area, where profiles are fed. The cutting buffer area includes a first cutting buffer area and a second cutting buffer area that are symmetrically arranged from left to right. The first and second cutting buffer areas are respectively equipped with a transverse conveyor chain and a marking and engraving gantry. The transverse conveyor chain conveys the strips or profiles from the discharge roller conveyor to the marking and engraving gantry. The marking and engraving gantry is equipped with a laser marking and engraving unit, which marks and engraves the strips or profiles. The marked and engraved strips or profiles are buffered on the transverse conveyor chain and then conveyed to the cutting and loading area. The cutting and feeding area includes a first cutting and feeding area and a second cutting and feeding area that are symmetrically arranged from left to right. The first cutting and feeding area and the second cutting and feeding area are respectively provided with a feeding conveyor roller line and a clamping and feeding mechanism. The clamping and feeding mechanism clamps one end of the strip or profile and feeds it to the cutting area along the feeding conveyor roller line. The cutting area includes a first cutting area and a second cutting area that are symmetrically arranged from left to right. Each of the first and second cutting areas is equipped with a cutting robot, which cuts strips or profiles. The short material discharge area includes a first short material discharge area and a second short material discharge area that are symmetrically arranged on both sides. The first short material discharge area and the second short material discharge area are respectively equipped with a length detection mechanism, a pusher rod, and a conveying device.

[0008] Furthermore, the clamping and feeding mechanism in the cutting and feeding area adopts precision guide rail guidance and gear rack transmission, and the feeding of the feeding conveyor roller line is controlled by a servo motor. The servo motor is the external axis of the cutting robot and is controlled by the cutting robot.

[0009] Furthermore, the first cutting area and the second cutting area are respectively equipped with a cutting chamber and a fume processor. The cutting chamber controls the fume from cutting strips or profiles inside, and the fume from the cutting chamber is discharged after being treated by the fume processor.

[0010] Furthermore, the length detection mechanism defines strips or profiles with a length less than 4m as short materials and strips or profiles with a length greater than 4m as long materials.

Detailed Implementation

[0015] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] This invention discloses an automated production line for cutting strips and profiles, such as... Figure 1 As shown, it includes, from front to back, the strip feeding area 1, the chamfering buffer area 2, the slag cleaning and chamfering area 3, the cutting buffer area, the cutting and feeding area, the cutting area, the short material discharge area, the long material grinding area, and the long material discharge area.

[0017] The strip cutting area 1 is equipped with a multi-head cutting machine and a rolling worktable. The multi-head cutting machine can use flame cutting, plasma cutting or laser cutting to cut the whole steel plate into strips of the required width. After cutting, the rolling worktable works to transport the strips to the chamfering buffer area.

[0018] The chamfering buffer area 2 is equipped with conveyor rollers or chains in two directions. One conveyor roller or chain is set along the flow line to receive the strips from the strip feeding area 1. The other conveyor roller or chain buffers the strips and separates them through a magnetic attraction mechanism before conveying them to the slag cleaning and chamfering area 3. One of the conveyor rollers or chains is equipped with a lifting mechanism to avoid the other conveyor roller or chain.

[0019] The slag removal and chamfering zone 3 is equipped with a feeding roller conveyor, a grinding and slag removal machine, a chamfering machine, and a discharge roller conveyor. The feeding and discharge roller conveyors in the slag removal and chamfering zone 3 adopt roller conveyor lines. The grinding and slag removal machine uses abrasive belts and grinding wheels for grinding, so as to avoid being squeezed into the parent material by the subsequent chamfering machine and affecting the quality. The feeding roller conveyor feeds the strip material, and the grinding and slag removal machine and the chamfering machine grind and chamfer the four corners of the strip panel. The chamfering machine completes the chamfering of the four corners of the panel, and the chamfering radius is about R2-R3. The grinding and slag removal machine and the chamfering machine are arranged in series, and the two processes are completed in one line.

[0020] like Figure 1 As shown, the side of the slag cleaning and chamfering zone 3 is provided with a profile feeding zone 16. Profiles are directly fed in the profile feeding zone 16. When passing through the slag cleaning and chamfering zone 3, the grinding and slag cleaning machine and the chamfering machine do not work. The profiles are directly conveyed to the chamfering discharge roller conveyor. The subsequent process flow is the same as that of the strip material.

[0021] The processed strips or profiles that are directly fed are conveyed to the cutting buffer area via the discharge roller conveyor. The cutting buffer area includes a first cutting buffer area 4 and a second cutting buffer area 10 that are symmetrically arranged on the left and right. The first cutting buffer area 4 and the second cutting buffer area 10 are respectively equipped with a transverse conveyor chain and a coding and marking gantry. The transverse conveyor chain conveys the strips or profiles from the discharge roller conveyor to the coding and marking gantry for positioning and clamping, ensuring the workpiece position of the strips or profiles.

[0022] The inkjet marking and marking gantry has the freedom to move along the length of the strip or profile and to rise and fall vertically. The inkjet marking and marking gantry is equipped with a position detection sensor to detect the position of the strip or profile. The inkjet marking and marking gantry is equipped with a laser engraving and marking unit to inkjet mark and mark the strip or profile. The inkjet-marked strip or profile is buffered on the transverse conveyor chain and then conveyed to the cutting and feeding area.

[0023] like Figure 1 As shown, the cutting and feeding area includes a first cutting and feeding area 5 and a second cutting and feeding area 11 that are symmetrical from left to right. The first cutting and feeding area 5 and the second cutting and feeding area 11 are respectively provided with a feeding conveyor roller line and a clamping and feeding mechanism. The feeding is controlled by a servo motor. The clamping and feeding mechanism clamps one end of the strip or profile and feeds it to the cutting area along the feeding conveyor roller line.

[0024] The cutting area includes a first cutting area 6 and a second cutting area 12 that are symmetrical from left to right. Each of the first cutting area 6 and the second cutting area 12 is equipped with a cutting robot. The cutting robot cuts strips or profiles. The clamping and feeding mechanism of the cutting and feeding area adopts precision guide rail guidance and gear rack transmission. The feeding of the feeding conveyor roller line is controlled by a servo motor. The servo motor is the external axis of the cutting robot and is controlled by the cutting robot.

[0025] The first cutting zone 6 and the second cutting zone 12 are also equipped with a cutting chamber and a fume processor, respectively. The cutting chamber controls the fume from cutting strips or profiles inside, and the fume from the cutting chamber is discharged after being treated by the fume processor.

[0026] The short material discharge area includes a first short material discharge area 7 and a second short material discharge area 13, which are symmetrically arranged on the left and right. The first short material discharge area 7 and the second short material discharge area 13 are respectively equipped with a length detection mechanism, a pusher rod and a conveying device. The length detection mechanism divides the cut strips or profiles into long materials and short materials according to the set length. The length detection mechanism defines strips or profiles with a length of less than 4m as short materials and strips or profiles with a length of more than 4m as long materials. Long materials are conveyed to the long material grinding area by the conveying device, and short materials are pushed into the material frame by the pusher rod.

[0027] The long material grinding area includes a first long material grinding area 8 and a second long material grinding area 14 that are symmetrically arranged on the left and right. The first long material grinding area 8 and the second long material grinding area 14 are respectively equipped with a long material turning mechanism and a long material grinding mechanism. The long material grinding machine grinds the cut surface of strips or profiles. In actual operation, manual grinding can also be used to grind the cut surface of the workpiece.

[0028] like Figure 1 As shown, the long material discharge area includes a first long material discharge area 9 and a second long material discharge area 15 that are symmetrically arranged on the left and right. The first long material discharge area 9 and the second long material discharge area 15 are respectively equipped with discharge push rods. The processed long material is pushed into the tray through the discharge push rods.

[0029] When using, such as Figure 1 As shown, the first cutting buffer area 4 and the second cutting buffer area 10, the first cutting feeding area 5 and the second cutting feeding area 11, the first cutting area 6 and the second cutting area 12, the first short material discharge area 7 and the second short material discharge area 13, the first long material grinding area 8 and the second long material grinding area 14, the first long material discharge area 9 and the second long material discharge area 15 can all be...

Step 6) The strip is conveyed to the marking and engraving gantry in the cutting buffer area. The laser marking and engraving unit is started to perform marking and engraving (QR code, Chinese and English characters). The workpiece after marking and engraving is moved laterally and buffered on the transverse conveyor chain. Step 7) The clamp carriage pushes the strip to be cut into the cutting area, where the plasma cutter performs the cutting in a closed space; Step 8) The length detection mechanism divides the cut strips into long and short pieces according to the set length; Step 9) The short material is pushed into the material frame by the pusher rod for unloading; Long materials are conveyed to the long material grinding area, and after grinding, they are conveyed to the long material discharge area for unloading.

[0030] The production method of profiles includes the following steps: Step 1) Use the workshop overhead crane to lift the profiles to the profile loading area 16; Step 2) After the profile passes through the slag removal and chamfering zone 3, the grinding and slag removal machine and the chamfering machine are not working, and the profile is directly conveyed to the discharge roller conveyor; Step 3) The profile is conveyed to the inkjet marking gantry in the cutting buffer area, and the laser marking unit is started to perform inkjet marking (QR code, Chinese and English characters).
