Description

Technical Field

[0001] The invention relates to the technical field of profile cutting equipment, in particular to an automatically assembled cold-bending forming and cutting mechanism for warehouse door tracks. Background Art

[0002] The warehouse door track is a C-shaped component made of steel strips through a cold-bending machine using a die. After the track is processed, it needs to be stacked for easy placement and transportation. However, during stacking, since the track has an opening, it is difficult to control the accuracy of stacking by directly stacking, which easily takes up more space. Moreover, after direct stacking, each track exists independently and has no restraining force between each other, which leads to low stability of the entire stack and is prone to falling apart.

[0003] Therefore, based on the above two problems, after the rails are processed, the two rails are currently fastened together to achieve the purpose of reducing space and improving the stability of the entire stack. However, the existing fastening method is through manual fastening. When fastening, the whole rail is cut to a fixed length, and the cut rail is fastened manually. Since the rail needs to bear the weight of the entire warehouse door during use, the wall thickness of the rail is generally more than 4 mm, and the length is also more than 3000 mm. This leads to a high labor intensity when fastening, and the fastening efficiency is reduced as physical strength is consumed. In addition, manual fastening requires at least one staff member to be specially equipped, which increases labor costs.

[0004] Therefore, there is an urgent need for an automatic assembly warehouse door track cold bending forming cutting mechanism, which is used to automatically complete the buckling assembly by mechanical means after the track is cut, so as to reduce labor intensity and labor costs and improve buckling efficiency.

[0033] See attached Figure 1-4 , shown is an automatically assembled cold-bending cutting mechanism for warehouse door rails, including a cutting unit and a transfer unit, wherein the cutting unit includes a support frame 1, a cutting saw 2 is hinged on the support frame 1 through a hinge seat, and a cutting drive cylinder 10 is hinged on the support frame 1, and the output end of the cutting drive cylinder 10 is hinged to the cutting saw 2. When cutting, the entire cutting saw 2 is driven to rotate along the hinge seat by the cutting drive cylinder 10, and the cutting of the rail 34 is completed by the saw blade of the cutting machine. At the same time, a cutting table 11 is provided on the support frame 1 at the saw blade position of the cutting machine, and a material loading table 14 and a clamping drive cylinder 12 are provided on the cutting table 11. A clamping plate 13 is provided at the output end of the clamping drive cylinder 12. When cutting, the rail 34 is placed on the material loading table 14, and then the clamping drive cylinder 12 drives the clamping plate 13 to complete the clamping of the rail 34;

[0034] At the same time, a ground rail 4 is provided at the bottom of the support frame 1 through a pulley, and a lead screw is provided at the bottom of the support frame 1 along the length direction of the ground rail 4, and a drive motor 6 is provided at one end of the lead screw. When the track 34 passing through the saw blade reaches a set length during cutting, the track 34 is clamped by the clamping drive cylinder 12, and the drive motor 6 is used to drive the cutting saw 2 to move along the track 34 and complete the cutting while clamping;

[0035] The transfer unit includes a frame 3, and the frame 3 is bolted to the support frame 1 through a connecting plate 5, thereby connecting the frame 3 and the support frame 1 as a whole, ensuring that the position of the track 34 on the frame 3 is consistent each time;

[0036] Furthermore, a plurality of conveying rollers 7 are provided on the frame 3, and the plurality of conveying rollers 7 are connected by a driving chain 8 and rotated by a conveying motor 9. When the rail 34 is cut to a fixed length and falls onto the conveying roller 7, the conveying roller 7 conveys the rail 34 forward through the conveying motor 9.

[0037] A push unit is provided on one side of the frame 3, and the push unit includes two mounting frames 29 arranged on one side of the frame 3. A push drive cylinder 30 is provided on the top of the mounting frame 29. A push head 31 is provided at the output end of the push drive cylinder 30 along the axial direction of the conveying roller 7. When in use, after the track 34 cut for the first time is transported by the conveying roller 7 to between the two push drive cylinders 30, the push drive cylinder 30 drives the push head 31 to push the track 34 to one side of the frame 3, waiting to be fastened and assembled with the track 34 cut for the second time.

[0038] A support plate 15 is horizontally arranged inside the frame 3, and a buckling unit is arranged on the support plate 15. The buckling unit includes two stopper drive cylinders 16 arranged on one side of the support plate 15 and two flip drive cylinders 18 arranged on the other side of the support plate 15, wherein the flip drive cylinder 18 is hinged on the support plate 15, and a connecting rod 19 is hinged on the output end, and a flip arm 20 is respectively arranged at both ends of the connecting rod 19, and the flip arm 20 includes a connecting portion 23, when the track 34 moves on the conveying roller 7, the connecting portion 23 is in a horizontal state, and its position is not higher than the conveying roller 7, a first stop portion 24 and a second stop portion 25 are arranged at one end of the connecting portion 23, and an accommodating opening 26 capable of accommodating the width of a track 34 is arranged between the first stop portion 24 and the second stop portion 25, and the accommodating opening 26 is colinear with the moving direction of the track 34 at the cutting saw 2, when the track 34 coming out of the cutting table 11 is just located in the accommodating opening 26, at the same time, the height of the second stop portion 25 is smaller than the first stop portion 24, and smaller than half of the height of the track 34;

[0039] In addition, the other end of the connecting portion 23 is hinged with a rotating arm 21 through a rotating shaft 22, and the rotating arm 21 is fixed on the supporting plate 15;

[0040] Furthermore, the stopper driving cylinder 16 is vertically arranged on the support plate 15, and a stopper plate 17 is arranged on the output end, the stopper plate 17 is located between two adjacent conveying rollers 7, and the stopper plate 17 is located below the rail 34 falling from the accommodating opening 26, the stopper plate 17 comprises a stopper portion 32 and a lifting portion 33 which are vertically arranged to each other, wherein the width of the lifting portion 33 is greater than the width of the rail 34, when the rail 34 is pushed forward by the pushing driving cylinder 30 and abuts against the side wall of the stopper portion 32, the stopper portion 32 is used to limit and reference the rail 34, at this time, the lifting portion 33 is located below the rail 34, when the next rail 34 is cut, in order to prevent the previous rail 34 from moving with the conveying roller 7, the entire stopper plate 17 is lifted by the stopper driving cylinder 16, and the previous rail 34 is lifted by the lifting portion 33 to achieve separation from the conveying roller 7;

[0041] When fastening, the track 34 after the second cutting falls into the accommodating opening 26. At this time, the flip drive cylinder 18 is started, and the two flip arms 20 are lifted upward by the connecting rod 19. At this time, the two flip arms 20 move in a circular arc along the rotating shaft 22. When the flip arm 20 rotates at an angle greater than 90 degrees, the track 34 located in the accommodating opening 26 is flipped and vertically dropped under the action of gravity, and is fastened and paired with the previous track 34 below. In this way, the fastening and pairing of the front and rear tracks 34 are completed by mechanical means instead of manpower, which further reduces labor intensity and saves labor costs, and can continuously maintain a high fastening efficiency.

[0042] In addition, the connecting portion 23 is provided with an inclined block 27 of a right-angled triangle structure between the first stop portion 24 and the second stop portion 25. The height of the inclined block 27 gradually decreases along one side of the second stop portion 25. When the connection portion 23 is engaged and flipped, the center of gravity of the track 34 can be tilted forward more quickly through the inclined block 27, thereby accelerating the fall of the track 34 from the receiving opening 26 and preventing the track 34 from being retained in the receiving opening 26.

[0043] Furthermore, the highest point of the tilting block 27 on the connecting portion 23 is not higher than the conveying roller 7, and the highest point of the tilting block 27 is flush with the highest point of the second stopper 25, so that the track 34 can be prevented from interfering with the tilting block 27 when moving on the conveying roller 7, and from interfering with the second stopper 25 when the track 34 is pushed outward by the push drive cylinder 30;

[0044] Furthermore, a plurality of adjustment holes 28 are provided on the connecting portion 23 along the length direction, and the second stop portion 25 is threadedly connected to the connecting portion 23 through the adjustment holes 28, and the distance between the first stop portion 24 and the second stop portion 25 can be adjusted through the adjustment holes 28 to adapt to the engagement of rails 34 of different widths.

[0045] Please refer to the attached Figure 5-8As shown, first, the flipping drive cylinder 18 is used to control the flipping arm 20 to be placed in a horizontal state, and then the cutting saw 2 is used to cut the formed rail 34 to a fixed length. The rail 34 after the first cutting falls on the conveying roller 7 and is transported to between the two pushing drive cylinders 30 through the conveying roller 7. Then, the pushing drive cylinder 30 uses the pushing head 31 to push the rail 34 forward and abut against the side wall of the stopper 32. At this time, the stopper drive cylinder 16 controls the stopper plate 17 to rise and uses the lifting part 33 to realize the previous rail 34 is separated from the conveyor roller 7, and then the next track 34 is cut. After the next track 34 is cut and placed in the accommodating port 26, the flip drive cylinder 18 is started to use the connecting rod 19 to lift the two flip arms 20 upward and rotate along the rotating shaft 22. When the flip arm 20 rotates 90 degrees, the track 34 in the accommodating port 26 is quickly flipped and buckled onto the track 34 below with the assistance of the tilting block 27. Then the stop plate 17 falls, and the two paired tracks 34 are carried out for the next step of palletizing.

[0046] It should be noted that when the push drive cylinder 30 is used to push the rail 34, the conveying roller 7 is in a pause position.

[0047] The above description is only a preferred specific implementation manner of the present invention, and is not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made according to the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
