Description

Technical Field

[0001] The invention relates to the technical field of metal profile laser cutting processing, and in particular to a metal profile multi-station laser cutting device. Background Art

[0002] When producing rectangular door and window frames (composed of two sets of symmetrical profiles, with both ends of each profile requiring chamfering), in order to make the splicing of the door and window frames more beautiful and easier to install, it is generally necessary to cut the edges and corners of the profiles that make up the door and window frames. Common cutting methods include manual cutting, power tool cutting, laser equipment cutting, and many others.

[0003] Among them, the cutting method using laser equipment has higher processing accuracy, its cut surface is relatively smooth and easy to splice. The current process of producing door frames using laser cutting equipment is as follows: each profile is placed on the laser cutting equipment in turn manually. Before cutting, the laser cutting equipment first positions the profile. After positioning, the laser cutting equipment cuts the two ends of the profile in turn. After cutting, the profile is removed and a new profile is placed. The above process is repeated to complete the cutting of multiple profiles.

[0004] The above cutting process still has the following problems: since the laser cutting equipment has relatively independent processing processes for each profile, there may be certain errors in the chamfers cut, and there may be gaps when the cuts of the two profiles are subsequently spliced ​​together, which in turn affects the strength of the frame after welding; at the same time, when this processing method is used to cut profiles, the above-mentioned loading, positioning, cutting and unloading need to be carried out separately, and the next process cannot be carried out when the previous process is not completed, which reduces the processing efficiency.

DETAILED DESCRIPTION

[0032] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

[0033] See also Figure 2 and Figure 3 A multi-station laser cutting equipment for metal profiles comprises a base, a center rod 1 is fixedly connected to the base, a connecting frame 2 is rotatably sleeved on the center rod 1, a driving mechanism 3 is connected to the center of the connecting frame 2, three clamping mechanisms 4 are evenly connected to the edge of the connecting frame 2 along the circumferential direction, a positioning mechanism 5 is connected to the center rod 1 and located above the driving mechanism 3, a cutting mechanism 6 for cutting profiles is connected to the top of the center rod 1, and a collecting container 7 is fixedly sleeved on the center rod 1 and located below the connecting frame 2.

[0034] See also Figure 2-Figure 4The driving mechanism 3 includes a central gear 31, and the central gear 31 is fixedly connected to the center of the connecting frame 2. The central gear 31 is rotatably sleeved on the central rod 1, and an incomplete gear 32 is meshed at the edge of the central gear 31. A circular plate 33 is fixedly sleeved on the central rod 1 and located above the central gear 31. The incomplete gear 32 is rotatably connected to the bottom of the circular plate 33. A driving motor 34 is fixedly connected to the upper end of the circular plate 33, and the driving shaft of the driving motor 34 is fixedly connected to the incomplete gear 32.

[0035] For specific work, see Figure 4 The positions of the clamping mechanisms 4 are as follows: one of the clamping mechanisms 4 is located in the loading area M, the clamping mechanism 4 next to the loading area M in the counterclockwise direction is located in the processing area N, the clamping mechanism 4 next to the loading area M in the clockwise direction is located in the unloading area P, and an arc plate 8 is fixedly connected to the outer wall of the collecting container 7 and located below the unloading area P.

[0036] The staff places two profiles to be processed in the clamping mechanism 4 in the loading area M, and aligns their ends through the corresponding positioning mechanism 5. Then, as the driving motor 34 rotates, the incomplete gear No. 1 32 is driven to rotate synchronously, thereby driving the center gear 31 and the connecting frame 2 to rotate counterclockwise by 120 degrees synchronously, so that the clamping mechanism 4 originally located in the loading area M moves to the processing area N together with the profiles thereon.

[0037] After the profile reaches the processing area N, the cutting mechanism 6 first descends to a certain height, and then cuts along the set path on the surface of the profile. At the same time, the clamping mechanism 4 will drive the profile to rotate 90 degrees intermittently while clamping the profile, so that the cutting mechanism 6 can cut each outer surface of the profile in turn (the state change of the profile before and after cutting is shown in FIG. Figure 1 As shown in the figure), after the cutting is completed, the center gear 31 and the connecting frame 2 are driven by the No. 1 incomplete gear 32 to continue to rotate counterclockwise by 120 degrees, and then the processed profile is transferred to the unloading area P. During this process, the clamping mechanism 4 holding the profile will move a certain distance outward along the center of the connecting frame 2 under the action of the arc plate 8, so that the main part of the profile is separated from the cut-off part. The cut-off part is separated from the positioning mechanism 5 under the action of its own gravity and falls into the collection container 7. After the above steps are completed, the staff located in the unloading area P takes the profile out of the clamping mechanism 4, and the processing of the profile is completed.

[0038] See also Figure 3 and Figure 7The clamping mechanism 4 includes a T-shaped plate 41, and the lower end surface of the T-shaped plate 41 is symmetrically fixedly connected to two rectangular plates, and a sliding rod 42 is fixedly connected between the two rectangular plates, and the sliding rod 42 is slidably connected to the connecting frame 2, and a return spring 43 is sleeved on the sliding rod 42. The return spring 43 is connected between the connecting frame 2 and the rectangular plate on the side close to the center rod 1. Under the action of the return spring 43, when the T-shaped plate 41 rotates with the connecting frame 2, except for the position directly above the arc plate 8, the T-shaped plate 41 is close to the center rod 1. The end surface of the rectangular plate close to the center rod 1 on the side away from the center rod 1 is fixedly connected with a semicircular block 81 that cooperates with the arc plate 8. The upper end surface of the T-shaped plate 41 is symmetrically fixedly connected to two vertical plates 44, and an intermittent rotating component 45 is commonly connected between the two vertical plates 44. The end surface of the vertical plate 44 away from the center rod 1 is connected to two symmetrical clamping tube components 46.

[0039] See also Figure 7 The clamping tube assembly 46 includes a rotating plate 461, which is rotatably connected to the end face of the vertical plate 44 away from the center rod 1 and corresponds to the position of the reversing gear 451. The end face of the rotating plate 461 away from the center rod 1 is fixedly connected to a cylindrical shell 462. The inner wall of the cylindrical shell 462 is symmetrically fixedly connected to two mounting rods 463. The two mounting rods 463 are parallel to each other and the angle between them and the upper end face of the T-shaped plate 41 is 45 degrees. The mounting rods 463 in the two cylindrical shells 462 are symmetrically arranged. The two mounting rods 463 in the same cylindrical shell 462 are fixedly connected to the inner wall of the cylindrical shell 462. A tooth plate 464 is slidably sleeved on the mounting rod 463, and a linkage gear 465 is meshed between the two tooth plates 464. An electric slider 466 is fixedly connected to the end of any one of the tooth plates 464, and the electric slider 466 is slidably sleeved on the mounting rod 463. A square housing 467 is fixedly connected to the front end of the cylindrical housing 462. A circular groove is commonly formed through the rotating plate 461, the cylindrical housing 462, the linkage gear 465 and the square housing 467, and a clamping module 468 is commonly connected to the cylindrical housing 462 and the square housing 467.

[0040] See also Figure 7The clamping module 468 includes a linkage rod 4681, and the front end surface of the tooth plate 464 is fixedly connected with the linkage rod 4681. The side walls of the cylindrical shell 462 and the square shell 467 are provided with a sliding groove with the same length direction as the length direction of the tooth plate 464. The linkage rod 4681 is slidably connected in the sliding groove and is centrally symmetrically distributed with the axis of the circular groove as the center of symmetry. Two right-angle frames 4682 are symmetrically fixedly connected to the rod body close to the lower linkage rod 4681 and located in the square shell 467, and a right-angle frame 4682 is also fixedly connected to the upper linkage rod 4681. The right-angle frame 4682 on the upper linkage rod 4681 is staggered with the two right-angle frames 4682 located on the lower linkage rod 4681 and located between the two. The end surfaces of the horizontal section and the vertical section of the right-angle frame 4682 and close to the axis of the circular groove are rotatably connected with clamping rollers 4683.

[0041] See also Figure 2 , Figure 5 and Figure 7 During specific operation, when the profile is not inserted, the right-angle frames 4682 on the two linkage rods 4681 on the clamping mechanism 4 of the loading area M are far away from each other. After the staff located in the loading area M inserts the two steel pipes to be cut into the circular groove in turn, the tooth plate 464 on it is pushed to move along the mounting rod 463 by the No. 1 electric slider 466, thereby driving the other tooth plate 464 to move synchronously. While moving, the two tooth plates 464 drive the two linkage rods 4681 to approach each other, and further, the two right-angle frames 4682 also approach each other, and then the profile can be clamped by the clamping roller 4683. After the profile is clamped by the clamping roller 4683, the profile is exactly located in the center of the circular groove. At this time, the profile is manually pushed to continue to move toward the position of the center rod 1, so that the profile can be docked with the positioning mechanism 5, and then the profile can be positioned and further clamped by the positioning mechanism 5.

[0042] See also Figure 3 and Figure 8 The intermittent rotation component 45 includes a reversing gear 451. Two symmetrically arranged reversing gears 451 are rotatably connected between the two vertical plates 44. The two reversing gears 451 are meshed with each other. Any one of the reversing gears 451 is meshed with a second incomplete gear 452. The second incomplete gear 452 is rotatably connected between the two vertical plates 44. The second incomplete gear 452 is connected to an actuator motor that drives it to rotate. The actuator motor is fixedly connected to the vertical plate 44 away from the center rod 1. A through groove is opened on the reversing gear 451 from front to back, and a connecting pipe module 453 is connected in the through groove.

[0043] See also Figure 8The connecting pipe module 453 includes a wedge block 4531, and the wedge block 4531 is slidably embedded in the through groove along the circumferential direction. The wedge block 4531 is connected to the reversing gear 451 through a contact spring 4532, and the end surface of the wedge block 4531 away from the center rod 1 is provided with an inclined surface.

[0044] See also Figure 3 , Figure 7 and Figure 8 During specific operation, after the profile is clamped and fixed at the center of the circular groove by the clamping roller 4683, the four wedge blocks 4531 abut against various surfaces of the profile under the action of the abutment spring 4532. After the profile is positioned by the positioning mechanism 5, the positioning mechanism 5 and the profile are driven to move synchronously to the processing area N through the connecting frame 2. Then the cutting mechanism 6 descends and moves along the set trajectory to cut the upper surface of the profile. When the upper surface cutting is completed, the second incomplete gear 452 is driven clockwise by the execution motor, thereby driving the reversing gear 451 on one side to rotate counterclockwise by ninety degrees, and the reversing gear 451 on the other side to rotate clockwise by ninety degrees. While the reversing gear 451 rotates, the profile is driven to rotate synchronously by ninety degrees through the wedge block 4531 and remain stationary for a period of time, so that the unprocessed surface of the profile can be switched to the top, so that the cutting mechanism 6 can cut the remaining surfaces.

[0045] In the above process, since the rotating plate 461 is rotationally connected to the vertical plate 44, when the profile rotates under the action of the reversing gear 451 and the wedge block 4531, the clamping roller 4683 also rotates synchronously, thereby ensuring that the profile is always located in the center of the circular groove, thereby ensuring the normal rotation of the profile.

[0046] See also Figure 2 , Figure 5 and Fig.11 The positioning mechanism 5 includes a mounting frame 51, a center rod 1 and two mounting frames 51 are fixedly sleeved above the center gear 31, an annular plate 52 is connected to the two mounting frames 51 for common rotation, and three inner support components 53 corresponding to the clamping mechanism 4 are connected to the outer wall of the annular plate 52 along the circumferential direction, and an annular guide plate 54 is fixedly connected to the outer side of the lower mounting frame 51, and the thickness of the annular guide plate 54 located below the unloading area P is less than the thickness of the annular guide plate 54 located below the processing area N and the loading area M.

[0047] See also Figure 5The inner support assembly 53 includes two connecting members 531 fixed on the outer wall of the annular plate 52, the end of the connecting member 531 away from the center rod 1 is rotatably connected to a hinge plate 532, the lower end surface of the hinge plate 532 is fixedly connected to a ball seat 533 through a round rod, the end of the hinge plate 532 away from the connecting member 531 is fixedly connected to a positioning plate 534, the end of the positioning plate 534 away from the connecting member 531 is connected to a connecting rod 535 through damping rotation, and the end of the connecting rod 535 away from the connecting member 531 is connected to an abutment module 536 for fixing the profile.

[0048] See also Figure 5 , Figure 6 , Figure 7 and Fig.10 The abutment module 536 includes a rectangular seat 5361, which is fixedly connected to the end of the connecting rod 535 away from the connecting member 531. Trapezoidal blocks 5362 are slidably embedded on the four end faces of the rectangular seat 5361. The trapezoidal blocks 5362 are connected to the rectangular seat 5361 through a connecting spring 5363. A No. 1 rope 5364 is slidably penetrated through the interior of the connecting rod 535 and the hinged plate 532. One end of the No. 1 rope 5364 close to the center rod 1 is fixedly connected to the connecting member 531, and the other end of the No. 1 rope 5364 away from the center rod 1 is fixedly connected to four No. 2 ropes 5365 corresponding to the four trapezoidal blocks 5362, and the corresponding No. 2 ropes 5365 and the trapezoidal blocks 5362 are fixedly connected.

[0049] During operation, the lower end of the ball seat 533 is always overlapped on the annular guide plate 54. Due to the height difference of the upper surface of the annular guide plate 54, when the ball seat 533 is located in the loading area M and the processing area N, the hinge plate 532 is in a horizontal state under the support of the ball seat 533 (see Figure 5 The state change of the middle connecting rod 535), after the profile is clamped and fixed in the center of the circular groove by the clamping roller 4683, when the staff pushes the profile to contact the positioning plate 534, the rectangular seat 5361 can be inserted into the profile. At the same time, the trapezoidal block 5362 abuts against the inner wall of the profile under the action of the connecting spring 5363, further clamping the profile.

[0050] After the profile is cut by the cutting mechanism 6, when the profile moves to the unloading area P along with the movement of the connecting frame 2, the semicircular block 81 will contact the arc plate 8 and slide along its side wall, thereby compressing the reset spring 43, and the connecting rod 535 slides outward along the connecting frame 2, and drives the main part of the profile to move outward synchronously through the clamping roller 4683 and the wedge block 4531. Since the thickness of the annular guide plate 54 in the unloading area P is thinner than that in the loading area M and the processing area N, It is impossible to form horizontal support for the bottom of the ball seat 533. When the ball seat 533 moves along the upper surface of the annular guide plate 54 to the unloading area P, the hinged plate 532 will tilt downward. During the tilting process, the No. 1 rope 5364 is stretched due to the rotation of the hinged plate 532, thereby driving the No. 2 rope 5365 to be stretched synchronously, and the traction connecting spring 5363 and the trapezoidal block 5362 to shrink synchronously, thereby releasing the pressure on the inner wall of the profile, so that the cut part of the profile can fall smoothly from the rectangular seat 5361.

[0051] See also Fig. 9 The cutting mechanism 6 includes an electric lifting slide 61, and the upper end of the center rod 1 is slidably connected to the electric lifting slide 61, the front end of the electric lifting slide 61 is fixedly connected to an electric push rod 62, the movable section of the electric push rod 62 is fixedly connected to a mounting seat 63, and a guide frame 64 is fixedly connected to the mounting seat 63, and sliding seats 65 are symmetrically slidably connected on the guide frame 64 and on both sides of the mounting seat 63, and the lower end of the sliding seat 65 is fixedly connected to a laser cutting machine 66 for cutting profiles, and the upper end of the sliding seat 65 and the upper end of the rectangular seat 5361 are jointly connected with a moving component 67, and the moving component 67 includes a No. 2 electric slider 671, and the No. 2 electric slider 671 is slidably connected to the upper end of the mounting seat 63 along the telescopic direction of the electric push rod 62, and the No. 2 electric slider 671 is hinged to the two sliding seats 65 through a connecting plate 672, and the two connecting plates 672 are symmetrical on the left and right.

[0052] During specific operation, when the two profiles move to the bottom of the processing area N mounting seat 63 and remain stationary, the electric lifting slide 61 descends, and the two laser cutting machines 66 are driven to descend synchronously through the electric push rod 62, the mounting seat 63, the guide frame 64 and the sliding seat 65. At the same time, the movable section of the electric push rod 62 automatically retracts and extends to adjust the two laser cutting machines 66 to the starting point of cutting. Then, during cutting, the electric push rod 62 drives the mounting seat 63 to retract and move during the retraction process. At the same time, the No. 2 electric slider 671 drives the two sliding seats 65 on the guide frame 64 to move in the same or opposite direction through the connecting plate 672 during the sliding process on the mounting seat 63. Under the joint action of the electric push rod 62 and the sliding seat 65, the laser cutting machine 66 can cut along any path on the profile surface within a certain range, and the moving paths of the two laser cutting machines 66 are symmetrical with each other with the retraction direction of the electric push rod 62 as the center axis.

[0053] Since the profile can rotate under the action of the wedge block 4531 and the reversing gear 451, and the two profiles rotate in opposite directions, by cooperating with the above-mentioned two laser cutting machines 66 that move along symmetrical paths, symmetrical chamfers can be cut at the ends of the two profiles at the same time, thereby improving processing efficiency.
