DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] A tube roll forming device with a welding station, such as Figure 1 , including a processing table 1, a mobile frame 2 and a welding mechanism 3 arranged at the top of the processing table 1 for welding the pipe, the mobile frame 2 is located above the right side of the welding mechanism 3, a support plate 4 is vertically provided at the top of the processing table 1, and a hanging plate 5 is provided on one side of the support plate 4, the mobile frame 2 is arranged on one side of the hanging plate 5 through a moving part, the moving part is used to drive the mobile frame 2 to move rightward on the hanging plate 5 and move downward at the same time, and a cutting mechanism for cutting the pipe is provided on the mobile frame 2.

[0034] like Figure 1 , the pipe is continuously conveyed to the right. After the pipe is welded by the welding mechanism 3, the pipe passes under one side of the moving frame 2. When the pipe with a defective weld moves to the bottom of the cutting mechanism, the moving frame 2 is driven by the moving part to move rightward on the hanging plate 5 while moving downward. At this time, the cutting mechanism on the moving frame 2 can cut the pipe with a defective weld from the pipe with a good weld. At this time, the pipe with a defective weld and the pipe with a good weld before can be reduced to form a whole pipe, which leads to the waste of the entire pipe.

[0035] When the speed of the movable frame 2 moving to the right is C, the speed of the pipe being continuously conveyed to the right is D, and C is equal to D, the pipe with a defective weld can be cut off from the pipe with a good weld during the process of the pipe being continuously conveyed to the right without stopping the conveyance of the pipe, which is simple and convenient to use.

[0036] The welding mechanism 3 may be a welding mechanism in a pipe welding forming mold with application number CN202311442898.3, which will not be described in detail in this application.

[0037] like Figure 1 and Figure 2 and Figure 5 The movable member includes a slide plate 6 horizontally slidably connected to one side of the hanging plate 5, and two opposite rectangular tubes 7 are provided at the bottom end of the slide plate 6, and rectangular rods 8 are vertically slidably connected in the two rectangular tubes 7. The movable frame 2 is arranged at the bottom end of the two rectangular rods 8, and two opposite side plates 9 are provided on the hanging plate 5, and a screw rod 10 is rotatably connected between the two side plates 9. One end of the screw rod 10 passes through the slide plate 6 and is threadedly connected to the slide plate 6. One of the side plates 9 is provided with a first motor 12 for driving the screw rod 10 to rotate. When the slide plate 6 and the movable frame 2 move horizontally in a direction away from the welding mechanism 3, the slide plate 6 is provided with a pushing member for driving the movable frame 2 to move vertically.

[0038] like Figure 1 and Figure 2 and Figure 5 When it is necessary to drive the moving frame 2 to move right on the hanging plate 5, it is only necessary to turn on the first motor 12. The rotating shaft of the first motor 12 drives the screw rod 10 to rotate. Because one end of the screw rod 10 passes through the slide plate 6 and is threadedly connected with the slide plate 6, when the screw rod 10 rotates, the slide plate 6 can be driven to slide right on the hanging plate 5. At this time, the moving frame 2 will follow the slide plate 6 to move right through the cooperation of the rectangular tube 7 and the rectangular rod 8. The rightward movement speed of the slide plate 6 and the moving frame 2 is consistent with the conveying speed of the pipe. In the process of the slide plate 6 and the moving frame 2 moving to the right, the moving frame 2 is driven by the pushing member to move vertically downward. At this time, the cutting mechanism on the moving frame 2 can cut the pipe with defective welds from the pipe with good welds during the conveying process. It is simple and convenient to use.

[0039] like Figure 2 and Figure 3 and Figure 4 and Figure 5The pusher includes a tension spring 13 arranged between the slide plate 6 and the mobile frame 2, the tension spring 13 is located between the two rectangular tubes 7, a groove 14 is provided on the side of the suspension plate 5 close to the mobile frame 2, a telescopic rod 15 is provided on the side of the mobile frame 2 close to the suspension plate 5, and the end of the telescopic rod 15 away from the mobile frame 2 extends into the groove 14, and a first push plate 16, a second push plate 17 and a third push plate 18 in the shape of a right triangle are provided at the bottom of the groove 14, the inclined surfaces of the first push plate 16 and the second push plate 17 are both facing downward, and the second push plate 1 7 is located above one side of the first push plate 16, and the first push plate 16 is flush with the inclined surface of the second push plate 17. The third push plate 18 is arranged above the first push plate 16 and is fixedly connected to the second push plate 17. The inclined surface of the third push plate 18 faces the notch of the groove 14. The telescopic rod 15 is rotatably connected with a swivel 19 located in the groove 14. The swivel 19 is located on the left side of the second push plate 17, and the outer wall of the swivel 19 contacts the inclined surface of the second push plate 17. A ball 20 is provided on one side of the telescopic rod 15 close to the bottom of the groove 14.

[0040] like Figure 2 and Figure 3 and Figure 4 and Figure 5 , the swivel 19 is located on the left side of the second push plate 17, and the outer wall of the swivel 19 contacts the inclined surface of the second push plate 17. This is the initial position of the mobile frame 2 and the telescopic rod 15. When the mobile frame 2 moves, the telescopic rod 15 will move with the mobile frame 2. In the process of the mobile frame 2 moving to the right, the swivel 19 on the telescopic rod 15 cooperates with the inclined surface on the second push plate 17, so that the mobile frame 2 can move downward while moving to the right. At this time, the tension spring 13 is stretched, and the rectangular rod 8 gradually slides out of the rectangular tube 7. When the swivel 19 rolls from the inclined surface on the second push plate 17 to the inclined surface of the first push plate 16, the swivel 19 and the inclined surface on the first push plate 16 are With the cooperation, the mobile frame 2 can continue to move downward while moving to the right. At this time, the cutting mechanism on the mobile frame 2 will cut the pipe. When the pipe cutting is completed, the swivel 19 is in contact with the inclined surface of the first push plate 16. Then, as the mobile frame 2 moves to the right, when the swivel 19 is separated from the inclined surface on the first push plate 16, the swivel 19 is located on the right side of the first push plate 16. At this time, the mobile frame 2 can be driven to move upward by the stretched tension spring 13 until the outer wall of the swivel 19 contacts the top groove wall of the groove 14. Then the mobile frame 2 moves to the left. At this time, the swivel 19 passes over the first push plate 16 until the mobile frame 2 is moved back to its original position.

[0041] When the mobile frame 2 moves to the left, the swivel 19 passes over the first push plate 16 until the mobile frame 2 is moved back to its original position. The ball 20 on the telescopic rod 15 contacts the inclined surface of the third push plate 18. At this time, as the mobile frame 2 moves to the left, the telescopic rod 15 can be squeezed and retracted by the cooperation of the ball 20 and the inclined surface of the third push plate 18. When the ball 20 rolls from the inclined surface of the third push plate 18 to the side of the second push plate 17 away from the bottom of the groove 14, and then as the mobile frame 2 moves to the left, After the ball 20 is separated from the second push plate 17, the telescopic rod 15 is extended, so that the swivel 19 provided on the telescopic rod 15 enters the groove 14. At this time, the telescopic rod 15 and the swivel 19 will be located on the left side of the second push plate 17. Through the above process, the movable frame 2 and the telescopic rod 15 can move downward while moving to the right. After the cutting mechanism on the movable frame 2 completes the cutting of the pipe, the movable frame 2 and the telescopic rod 15 are first moved upward and then moved leftward back to their original positions to facilitate the next cutting of the pipe. It is simple and convenient to use.

[0042] like Figure 4 and Figure 5 The telescopic rod 15 includes a sleeve 21 horizontally arranged on the mobile frame 2, and a slide post 22 is horizontally slidably connected in the sleeve 21, a compression spring 23 is arranged between the slide post 22 and the mobile frame 2, and the compression spring 23 is located in the sleeve 21, and the end of the slide post 22 away from the mobile frame 2 is located outside the sleeve 21 and extends into the groove 14, and the swivel 19 and the ball 20 are both arranged on the slide post 22. The purpose of this arrangement is that through the cooperation of the sleeve 21, the slide post 22 and the compression spring 23, the third push plate 18 can be pushed. When the inclined surface squeezes the ball 20, the slide post 22 slides into the sleeve 21. At this time, the compression spring 23 is compressed, and the telescopic rod 15 formed by the sleeve 21 and the slide post 22 will retract. When the ball 20 rolls from the inclined surface of the third push plate 18 to the side of the second push plate 17 away from the bottom of the groove 14, and then as the mobile frame 2 moves to the left, the ball 20 is separated from the second push plate 17, and the telescopic rod 15 formed by the sleeve 21 and the slide post 22 can be extended through the compressed compression spring 23, which is simple and convenient to use.

[0043] like Figure 1 and Figure 2 The movable frame 2 is inverted U-shaped, and the cutting mechanism includes a rotating shaft 24 rotatably connected between opposite sides of the movable frame 2, and the rotating shaft 24 is misaligned with the pipe, and two saw blades 25 for cutting the pipe are provided on the rotating shaft 24, and a second motor 26 for driving the rotating shaft 24 to rotate is provided on the movable frame 2.

[0044] like Figure 1 and Figure 2The pipe with defective welds is F, and the pipe with good welds is G. When the moving frame 2 moves to the right and moves downward at the same time through the moving member, the second motor 26 is turned on, and the rotating shaft of the second motor 26 drives the rotating shaft 24 to rotate, and the rotating shaft 24 drives the two saw blades 25 to rotate. At this time, when the moving frame 2 moves to the right and moves downward at the same time, F can be completely cut off from G by the two saw blades 25, and F is located between the two saw blades 25;

[0045] like Figure 8 , the number of saw blades 25 can also be one, when the moving frame 2 moves to the right and moves downward at the same time, the end of F connected to G can be cut by the saw blade 25, at this time F is located on the left side of the saw blade 25, and then the moving frame 2 moves back to its original position, and then with the transportation of the pipe, when F is completely located on the right side of the saw blade 25, the moving frame 2 moves to the right and moves downward at the same time again through the moving member, at this time F can be completely cut off from G by the saw blade 25, through the above process, when the moving frame 2 moves twice in a cycle, F can be completely cut off from G;

[0046] The length of F cut by one saw blade 25 is K, the length of F cut by two saw blades 25 is J, and K is greater than J.

[0047] like Figure 1 A collection box 27 is placed on the ground on the right side of the processing table 1, and a transfer piece is provided on the collection box 27. The transfer piece is used to support the pipe cut by the saw blade 25 and transfer the pipe cut by the saw blade 25 to the collection box 27. The purpose of this arrangement is that the cut pipe with defective welds can be transferred to the collection box 27 for collection through the transfer piece. At the same time, the pipe with defective welds is supported by the transfer piece, which reduces the situation where the cut pipe with defective welds is knocked away when it collides or contacts with the side wall of the rotating saw blade 25, thereby improving the safety of use and being simple and convenient to use.

[0048] like Figure 1 and Figure 2The transfer member includes two baffles 28 arranged at the top of the collection box 27, and the two baffles 28 are opposite to each other. A horizontal axis 29 is horizontally arranged between the two baffles 28, and the horizontal axis 29 is parallel to the pipe. A circular ring 30 is sleeved on the horizontal axis 29. Two vertical rods 31 are arranged on the outer wall of the circular ring 30, and the two vertical rods 31 are opposite to each other up and down. One end of the two vertical rods 31 away from the circular ring 30 is provided with a support cylinder 32, and the two support cylinders 32 are both located below between the two saw blades 25. The support cylinder 32 located above the circular ring 30 is sleeved on the pipe. A resistance column 33 is horizontally arranged on one side of the inner wall of the collection box 27. The support cylinder 32 located below the circular ring 30 is coaxial with the resistance column 33 and sleeved on the resistance column 33. When the mobile frame 2 moves in the direction of approaching or away from the welding mechanism 3, a connecting member for driving the circular ring 30 to move along the length direction of the horizontal axis 29 is provided on the mobile frame 2, and a power member for driving the circular ring 30 to rotate along the axis of the horizontal axis 29 is provided on one of the baffles 28.

[0049] like Figure 1 and Figure 2 and Figure 3 When the mobile frame 2 moves left and right to approach or move away from the welding mechanism 3, the ring 30 will follow the mobile frame 2 through the connecting piece. When the mobile frame 2 moves up and down, the ring 30 will not follow the mobile frame 2 up and down through the connecting piece.

[0050] After the pipe is welded by the welding mechanism 3, it passes through the support cylinder 32 located above the circular ring 30. When the support cylinder 32 above the circular ring 30 is located on the pipe with defective welds as the pipe is transported, it moves rightward and downward through the mobile frame 2. At this time, the circular ring 30 and the two support cylinders 32 follow the mobile frame 2 to move rightward along the length direction of the horizontal axis 29. At this time, the support cylinder 32 above the circular ring 30 can always be located on the pipe with defective welds. At this time, the support cylinder 32 located below the circular ring 30 moves out from the abutment column 33. When the mobile frame 2 moves rightward and downward, the pipe with defective welds is cut off from the pipe with good welds by two opposite saw blades 25. The cut pipe is located in the support cylinder 32 above the circular ring 30. At this time, the support cylinder 32 can reduce the occurrence of the cut pipe with defective welds being knocked away when it collides or contacts with the side wall of the rotating saw blade 25.

[0051] After the two saw blades 25 cut the pipe with defective welds from the pipe with good welds, the moving frame 2, the ring 30 and the two support cylinders 32 continue to move to the right. During the process of the moving frame 2, the ring 30 and the two support cylinders 32 continuing to move to the right, after the rotating ring 19 separates from the inclined surface of the first push plate 16, the tension spring 13 moves the moving frame 2 upward, and then the power member drives the ring 30 to rotate 180 degrees along the axis of the horizontal axis 29, so that the upper and lower support cylinders 32 are exchanged, and the cut pipe with defective welds can be transferred to the collection box 27.

[0052] Then, when the rotating ring 19 contacts the top groove wall of the groove 14 and the moving frame 2 moves back to the original position to the left, the support cylinder 32 located below the circular ring 30 will drive the cut pipe in the collection box 27 to move to the left, and the support cylinder 32 located above the circular ring 30 will be sleeved on the pipe delivered subsequently. When the moving frame 2 moves back to the original position, one end of the abutment column 33 will be coaxially inserted into the support cylinder 32 located below the circular ring 30 to push the pipe in the collection box 27 out of the support cylinder 32. At this time, the pipe pushed out of the support cylinder 32 in the collection box 27 will fall to the bottom of the collection box 27.

[0053] like Figure 8 When the number of saw blades 25 is one, the saw blade 25 is located on the left side of the support tube 32. At this time, as the pipe is transported, when the pipe with a defective weld is located on the left side of the saw blade 25, the movable frame 2 moves rightward and downward at the same time through the moving member. At this time, the pipe with a defective weld and the end of the pipe with a good weld can be cut by the saw blade 25, and then the movable frame 2 moves upward and then leftward back to the original position to complete a cycle of movement;

[0054] When the moving frame 2 moves back to the original position to the left, the ring 30 and the support cylinder 32 will move to the left with the moving frame 2. At this time, the support cylinder 32 located above the ring 30 will be sleeved on the pipe with the defective weld. Then, as the pipe is transported, when the pipe with the defective weld is completely located on the right side of the saw blade 25, the moving frame 2 performs a second cycle movement through the moving parts to completely cut the pipe with the defective weld from the pipe with the good weld. At this time, the support cylinder 32 located above the ring 30 will be located on the pipe with the defective weld. At this time, the support cylinder 32 can reduce the situation that the cut pipe with the defective weld collides with the side wall of the rotating saw blade 25 and the cut pipe with the defective weld is blown away.

[0055] During the second rightward and downward movement of the mobile frame 2, after the pipe with defective welds is completely cut off from the pipe with good welds, the mobile frame 2, the ring 30 and the two support cylinders 32 continue to move to the right. During the second rightward movement of the mobile frame 2, the ring 30 and the two support cylinders 32, after the rotating ring 19 is separated from the inclined surface of the first push plate 16, the tension spring 13 moves the mobile frame 2 upward, and then the power member drives the ring 30 to rotate 180 degrees along the axis of the horizontal shaft 29, so that the upper and lower support cylinders 32 are exchanged, and the cut pipe with defective welds can be transferred to the collection box 27.

[0056] Then, when the rotating ring 19 contacts the top groove wall of the groove 14 and the movable frame 2 moves back to the left to complete the second cycle, the support tube 32 located below the ring 30 will drive the cut pipe in the collection box 27 to move to the left, and the support tube 32 located above the ring 30 will be sleeved on the pipe subsequently transported out. When the movable frame 2 moves back to its original position, one end of the abutment column 33 will be coaxially inserted into the support tube 32 located below the ring 30 to push the pipe in the collection box 27 out of the support tube 32. At this time, the pipe pushed out of the support tube 32 in the collection box 27 will fall to the bottom of the collection box 27, which is simple and convenient to use.

[0057] like Figure 6 and Figure 7 The horizontal shaft 29 is rotatably connected to the two baffles 28. The power member includes a sliding groove 34 arranged on the horizontal shaft 29 along the length direction of the horizontal shaft 29. A sliding plate 35 is horizontally slidably connected in the sliding groove 34. The side of the sliding plate 35 away from the bottom of the sliding groove 34 is fixedly connected to the inner wall of the ring 30. One of the baffles 28 is provided with a third motor 36 for driving the horizontal shaft 29 to rotate.

[0058] like Figure 6 and Figure 7 When it is necessary to drive the ring 30 to rotate along the axis of the horizontal shaft 29, it is only necessary to turn on the third motor 36. At this time, the rotating shaft of the third motor 36 will drive the horizontal shaft 29 to rotate. At this time, the horizontal shaft 29 will drive the ring 30 to rotate along the rotating axis of the horizontal shaft 29 through the cooperation of the sliding groove 34 and the sliding plate 35. When the ring 30 follows the moving frame 2 to move along the length direction of the horizontal shaft 29 through the connecting piece, the ring 30 will drive the sliding plate 35 to slide in the sliding groove 34. The connecting piece will not affect the rotation of the ring 30, and it is simple and convenient to use.

[0059] like Figure 2 and Figure 6 The connecting member includes a rotating drum 37 coaxially connected to one side of the ring 30, and an L-shaped connecting rod 38 is provided on one side of the outer wall of the rotating drum 37. A slot 39 is provided at the top end of the vertical edge of the connecting rod 38, and an insertion rod 40 is vertically inserted in the slot 39. The top end of the insertion rod 40 extends to the outside of the slot 39 and is fixedly connected to the bottom end of the movable frame 2.

[0060] like Figure 2 and Figure 6 When the movable frame 2 moves to the right, the movable frame 2 will drive the ring 30 to move through the cooperation of the rotating cylinder 37, the connecting rod 38, the slot 39 and the insertion rod 40. When the movable frame 2 moves downward, the insertion rod 40 will gradually be inserted into the slot 39, and the bottom end of the insertion rod 40 is always located in the slot 39. When the ring 30 rotates, because the rotating cylinder 37 is rotatably connected with the ring 30, the movable frame 2, the insertion rod 40 and the rotating cylinder 37 will not affect the rotation of the ring 30, and it is simple and convenient to use.

[0061] like Figure 1 A plurality of pads 41 are vertically provided at the top of the outer wall of the sleeve 21, and the top of each pad 41 contacts the bottom end of the pipe. Each pad 41 is spaced apart along the length direction of the sleeve 21, and the top surface of each pad 41 is an arc-shaped surface. A support ring 42 is provided at the top of the baffle 28 away from the processing table 1, and the support ring 42 is sleeved on the pipe. The purpose of this arrangement is to support the pipe through the support ring 42 and each pad 41, reduce the influence of gravity on the pipe, and reduce the downward bending of the pipe. It is simple and convenient to use.

[0062] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
