Description

Technical Field

[0001] The invention belongs to the technical field of laser processing equipment, in particular to a pipe laser cutting machine capable of automatic loading and unloading. Background Art

[0002] Metal pipes are tubular objects made of stainless steel, carbon steel, alloy steel, etc., and are widely used in industries such as aircraft manufacturing, engineering machinery, and the automotive industry. During the production and processing of metal pipes, in order to make the metal pipes meet the requirements of subsequent processing and assembly, in some cases, it is necessary to cut the metal pipes into multiple sections at equal distances by laser cutting.

[0003] Patent publication number CN117532178B discloses a pipe laser cutting machine comprising a machine platform, a laser cutting head, a feed rack, and a stock rack disposed on top of the machine platform. The stock rack is used to place the pipe to be processed, and the feed rack is located between the stock rack and the laser cutting head. A transmission drive is provided on top of the machine platform for driving the feed rack toward the stock rack or the laser cutting head. A clamping assembly is provided on top of the feed rack, and a lifting drive is provided on the feed rack for driving the clamping assembly up and down. An alignment assembly is provided on top of the machine platform. The lifting drive and alignment assembly are used to align the clamping midpoint of the clamping assembly with the centerline of the pipe placed on the stock rack. This patent has the effect of improving the quality of laser cutting of pipes.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] Although pipes can be cut automatically, when a complete pipe needs to be cut into multiple sections at equal distances, the number of cut pipes may be large. Therefore, in order to facilitate the transportation and storage of the cut pipes, it is usually necessary to use a pipe receiving box to receive the cut multiple sections of pipes. When the cut multiple pipes fall into the box, they may be piled up in the box in a relatively messy state, which not only fails to reasonably utilize the storage space of the box, but also affects the subsequent further processing of the pipes due to the disorder. Moreover, usually, after the pipe is cut into multiple sections, the cutting quality of each section of the pipe needs to be checked. When the pipes are piled up in the box in a messy state, it is not conducive to the smooth progress of the inspection work. Summary of the Invention

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. The present invention relates to a pipe laser cutting machine capable of automatic loading and unloading. The end of the plum blossom tube to be cut is placed between two clamping plates, and then the motor eight is used to drive the bidirectional threaded rod to rotate, so that the two clamping plates are close to each other to clamp the plum blossom tube. Then, according to the length of the plum blossom tube to be cut, the motor seven is used to drive the threaded rod six to rotate, so that the lifting plate moves up and down, and the distance between the bottom of the plum blossom tube and the laser cutting head can be adjusted. Then, the electric push rod three is used to drive the laser cutting head close to the plum blossom tube, and the laser cutting head is turned on. The laser cutting head is used to cut the plum blossom tube. At the same time, the motor six is ​​used to drive the rotating plate to rotate, so that the plum blossom tube rotates, and the laser cutting head performs circular cutting on the plum blossom tube. By continuously driving the plum blossom tube to descend and using the laser cutting head to perform cutting work, a complete plum blossom tube can be cut into multiple sections, thereby realizing automatic loading and cutting of the plum blossom tube, which is more efficient and convenient.

[0024] 2. The laser cutting machine for pipes with automatic loading and unloading according to the present invention utilizes a positioning and placing mechanism and a material unloading auxiliary mechanism. When the plum blossom pipe is cut at equal intervals, the groove of the cut pipe slides along the adjusting rod, so that the cut multiple sections of pipe are stacked in an orderly manner in the box, realizing automatic unloading and rationally utilizing the storage space of the box, which is beneficial to further transporting and processing the pipes. Moreover, since the box is divided into multiple groups of stacked pipes, and the edges of each group of stacked pipes are aligned due to the limitation of the adjusting rod, it is also beneficial to inspect the cutting quality of each group of pipes, thereby improving the inspection efficiency. Moreover, whenever a pipe starts to slide down the adjusting rod, the push block rotates and extends from the groove of the adjusting rod, and then drives the slider to slide down along the groove of the adjusting rod. The push block can push the pipe in the sliding process, thereby promoting its movement by applying external force to the sliding pipe, thereby avoiding the pipe being stuck when the pipe slides down the adjusting rod due to the rough surface of the pipe. The situation that multiple adjusting rods cannot be lowered normally further ensures the normal collection of pipes, and before the pipes are placed in the box, the box space dividing mechanism can be used to divide the inner cavity of the box into multiple placement channels according to the diameter of the pipes, and then the adjusting rods are used to place the pipes one by one and place them in sequence along the placement channels. The pipes being stacked will be limited by the adjusting rods, and the pipes that have been stacked will be limited by the plate one and the plate two. When multiple groups of stacked pipes are evenly placed in a placement channel, a blocking effect will be exerted between adjacent pipes until a sufficient number of pipes are placed in the multiple placement channels divided by the plate one and the plate two. During the entire placement process, the stacked pipes will be limited by the adjusting rods, the plate one, the plate two, and the edge of the box and will not collapse, thereby avoiding the situation that when the adjusting rod is separated from the pipes that have been stacked, the stacked pipes cannot be limited and collapse, resulting in the neatly stacked pipes still being messy, further ensuring the neatness of the pipes in the box.

[0053] Specifically, in the prior art, although the pipe can be automatically cut, when a complete pipe needs to be cut into multiple sections at equal distances, the number of cut pipes may be large. Therefore, in order to facilitate the transportation and storage of the cut pipes, it is usually necessary to use a pipe receiving box to receive the cut multiple pipe sections. When the cut multiple pipes fall into the box, they may be piled up in a relatively messy state in the box, which not only fails to reasonably utilize the storage space of the box, but also affects the subsequent further processing of the pipes due to the disorder. Moreover, usually, after the pipe is cut into multiple sections, the cutting quality of each pipe section needs to be inspected. When the pipes are piled up in a disorderly state in the box, it is not conducive to the smooth progress of the inspection work.

[0054] Therefore, in order to solve the above problems, this embodiment is used for plum blossom tubes. The plum blossom tube is called plum blossom tube because its cross section is similar to that of a plum blossom. This type of tube is more common in industry. The tube material receiving box for receiving the cut tubes is placed on the carrier 10, and one corner of the box body is aligned with the angle of one side of the clamping block 20. Then, the electric push rod 18 drives the clamping block 19 to move until the clamping block 19 is aligned with the angle of the other side of the box body. Then, with the cooperation of the clamping block 19 and the clamping block 20, the box body can be fixed. Then, the motor 3 12 drives the threaded rod 3 13 to rotate, so that the slot plate 1 2 is lowered. The plurality of adjusting rods 44 are extended into the inner cavity of the box, and the lower ends of the adjusting rods 44 are fitted with the bottom of the inner cavity of the box. Furthermore, the motor 16 drives the threaded rod 15 to rotate, the motor 527 drives the threaded rod 528 to rotate, the motor 11 drives the threaded rod 82 to rotate, and the motor 417 drives the threaded rod 416 to rotate, so that the fixed ring 43 and the rotating plate 38 can move in the X and Y axis directions, and the axis of the fixed ring 43 is coincident with the axis of the plum blossom tube. Then, according to the specifications of the plum blossom tube, the motor 941 is used to drive the gear 42 to rotate, so that the inclined groove ring 59 can be rotated, and the plurality of guide columns 58 can be driven simultaneously through the inclined groove. Move radially, the adjusting rod 44 slides on the fixing ring 43 until the plum blossom tube descends, and the groove on the surface of the plum blossom tube can fit with the surface of the adjusting rod 44, and then the motor 13 57 drives the threaded rod 10 56 to rotate, so that the plum blossom tube to be cut descends and extends between multiple adjusting rods 44, and then the cutting method in the above embodiment is used to perform equidistant cutting, and the cut pipe will slide downward along the adjusting rod 44, so that multiple sections of pipes can be stacked and placed in the box, and because the adjusting rod 44 fits with the groove on the surface of the pipe, no deflection will occur during the descending process of the pipe, which makes the cutting easier. The edges of the multiple sections of pipes are aligned. When the pipes stacked in one area of ​​the box reach a certain height, the position of the adjusting rod 44 is changed to place the subsequently cut pipes in the empty position of the box. Then, the above operation is repeated repeatedly to stack the multiple sections of pipes in the box in an orderly manner, realizing automatic unloading and making reasonable use of the storage space of the box, which is conducive to further transportation and processing of the pipes. In addition, since the box is divided into multiple groups of stacked pipes, and the edges of each group of stacked pipes are aligned due to the limit of the adjusting rod 44, it is also conducive to checking the cutting quality of each group of pipes, thereby improving the inspection efficiency.

[0055] The cut pipes can be slid down the adjusting rods 44 into the box for placement to ensure that the edges of each group of pipes are aligned. However, when the surface of the pipes is relatively rough, the friction between the surface of the pipes and the surface of the adjusting rods 44 is relatively large, and the pipes may be stuck between the multiple adjusting rods 44 and cannot slide down normally. Therefore, in order to avoid this situation, every time a pipe starts to slide down the adjusting rods 44, the motor 14 60 drives the push block 47 to rotate so that it extends out from the groove of the adjusting rod 44, and then the motor 10 46 drives the threaded rod 7 49 to rotate so that the slider 48 slides down along the groove of the adjusting rod 44. The push block 47 can push the pipes in the sliding process, thereby promoting their movement by applying external force to the sliding pipes, thereby avoiding the situation where the pipes are stuck between the multiple adjusting rods 44 and cannot slide down normally when the pipes slide down the adjusting rods 44 due to the rough surface of the pipes, thereby further ensuring the normal collection of the pipes.

[0056] Although the above method can realize the orderly placement of the cut pipes, the adjusting rod 44 needs to be continuously moved to satisfy the placement of the pipes in different positions in the box. Therefore, the stacked pipes can only be kept stable when the pipes are between multiple adjusting rods 44. When the adjusting rod 44 is separated from the stacked pipes, the stacked pipes cannot be limited and are prone to collapse due to external forces, such as vibration, accidental touch, etc., resulting in the neatly stacked pipes still being messy. Therefore, in order to avoid this situation, before the pipes are placed into the box, the motor 12 53 can be used to drive the threaded rod 9 54 to rotate according to the diameter of the pipes, so that the adjusting column 21 at the right end is adjusted. When the adjusting column 21 at the right end moves, the other adjusting columns 21 will also move due to the connecting rod 1 50 and the connecting rod 2 45, and the spacing between adjacent adjusting columns 21 will change equally until the spacing between adjacent adjusting columns 21 is close to the diameter of the pipe. Then, the motor 2 9 is used to drive the threaded rod 2 8 to rotate, so that the supporting platform 10 rises. At the same time, the electric push rod 2 25 is used to drive the push plate 24 to move. The push plate 24 pushes the plate body 2 23 to retract it into the inner cavity of the plate body 1 22. The spring 55 is compressed until the total length of the plate body 1 22 and the plate body 2 23 is equal to the width of the inner cavity of the box. At this time, the plate body 1 22 and the plate body 2 23 can be inserted into the inner cavity of the box and are aligned with the bottom of the inner cavity of the box. Fit, since the left end face of the leftmost plate 1 22 is flush with one side of the clamping block 2 20, the plate 1 22 and the plate 2 23 will also be at the left edge of the box inner cavity, and the plate 1 22 and the plate 2 23 inserted into the box will divide the placement space of the box inner cavity and divide the box inner cavity into multiple placement channels, while the plate 1 22 and the plate 2 23 outside the box will not play a dividing role. At this time, the adjusting rod 44 is used to place the pipes one by one, and they are placed in sequence along the placement channels. The pipes being stacked will be limited by the adjusting rod 44, and the pipes that have been stacked will be limited by the plate 1 22 and the plate 2 23. When a placement channel After multiple groups of stacked pipes are evenly placed inside, there will be a blocking effect between adjacent pipes, and then the above operation is repeated until a sufficient number of pipes are placed in the multiple placement channels divided by plate body 1 22 and plate body 2 23. At this time, plate body 1 22 and plate body 2 23 can be driven to extend from the box body. During the entire placement process, the stacked pipes will be limited by the adjusting rod 44, plate body 1 22, plate body 23, and the edge of the box body and will not collapse, thereby avoiding the situation where the stacked pipes cannot be limited and collapse when the adjusting rod 44 is separated from the stacked pipes, resulting in the neatly stacked pipes still being messy, further ensuring the neatness of the pipes in the box body.

[0057] Working principle: Place the end of the plum blossom tube to be cut between the two clamps 39, and then use the motor eight 36 to drive the bidirectional threaded rod 37 to rotate, so that the two clamps 39 can be brought close to each other to clamp the plum blossom tube. Then, according to the length of the plum blossom tube that needs to be cut, use the motor seven 31 to drive the threaded rod six 35 to rotate, so that the lifting plate 29 moves up and down, and the distance between the bottom of the plum blossom tube and the laser cutting head 32 can be adjusted. Then use the electric push rod three 33 to drive the laser cutting head 32 close to the plum blossom tube, and turn on the laser cutting head 32, and use the laser cutting head 32 to cut the plum blossom tube. At the same time, use the motor six 30 to drive the rotating plate 38 to rotate, so that the plum blossom tube rotates, and the laser cutting head 32 performs circular cutting on the plum blossom tube. By continuously driving the plum blossom tube down and using the laser cutting head 32 performs cutting work, and can cut a complete plum blossom tube into multiple sections, thereby realizing automatic loading and cutting of the plum blossom tube, which is more efficient and convenient. The pipe material receiving box for receiving the cut pipes is placed on the carrier 10, and one corner of the box body is matched with the angle of one side of the clamping block 20, and then the electric push rod 18 drives the clamping block 19 to move until the clamping block 19 is matched with the angle of the other side of the box body, and the box body can be fixed with the cooperation of the clamping block 19 and the clamping block 20, and then the motor 3 12 drives the threaded rod 3 13 to rotate, so that the groove plate 12 is lowered, and the multiple adjusting rods 44 are extended into the inner cavity of the box, and the lower end of the adjusting rod 44 is matched with the bottom of the inner cavity of the box, and the motor 16 drives the threaded rod 15 to rotate, and the motor 5 27 drives the threaded rod 13 to rotate. By rotating the threaded rod five 28, driving the threaded rod eight 52 to rotate by the motor eleven 51, and driving the threaded rod four 16 to rotate by the motor four 17, the fixed ring 43 and the rotating plate 38 can both move in the X and Y axis directions, and the axis center of the fixed ring 43 coincides with the axis center of the plum blossom tube. Then, according to the specifications of the plum blossom tube, the motor nine 41 is used to drive the gear 42 to rotate, so that the inclined groove ring 59 can be rotated, and the inclined groove can simultaneously drive multiple guide columns 58 to move radially at the same time. The adjusting rod 44 slides on the fixed ring 43 until the plum blossom tube descends, and the groove on the surface of the plum blossom tube can fit with the surface of the adjusting rod 44. Then, the motor thirteen 57 is used to drive the threaded rod ten 56 to rotate, so that the plum blossom tube to be cut descends, so that it extends between the multiple adjusting rods 44, and then the above-mentioned cutting method is used. The cut pipes are cut in an equidistant manner, and the cut pipes slide downward along the adjusting rod 44, so that multiple sections of pipes can be stacked and placed in the box. Moreover, since the adjusting rod 44 fits in the groove on the surface of the pipe, no deflection occurs during the falling process of the pipe, which makes the edges of the cut multiple sections of pipes aligned. When the pipes stacked in one area of ​​the box reach a certain height, the position of the adjusting rod 44 is changed to place the subsequent cut pipes in the empty position of the box. Then, the above operation is repeated repeatedly to make the cut multiple sections of pipes stacked in an orderly manner in the box, realizing automatic unloading and making reasonable use of the storage space of the box, which is conducive to further transportation and processing of the pipes. Moreover, since the box is divided into multiple groups of stacked pipes,The edges of each group of stacked pipes are aligned due to the limitation of the adjusting rod 44, which is also conducive to checking the cutting quality of each group of pipes and improving the inspection efficiency. Although the cut pipes can slide down along the adjusting rod 44 into the box for placement to ensure the alignment of the edges of each group of pipes, when the surface of the pipes is relatively rough, the friction between the surface of the pipes and the surface of the adjusting rod 44 is relatively large, and the pipes may be stuck between multiple adjusting rods 44 and cannot slide down normally. Therefore, in order to avoid this situation, every time a pipe starts to slide down along the adjusting rod 44, the motor 14 60 will drive the push block 47 to rotate so that it extends out from the groove of the adjusting rod 44, and then the motor 10 46 drives the threaded rod 7 49 to rotate so that the slider 48 moves along the adjusting rod 44. When the groove slides down, the push block 47 can push the pipe in the sliding process, thereby promoting its movement by applying external force to the sliding pipe, thereby avoiding the situation that the pipe is stuck between multiple adjusting rods 44 and cannot descend normally when the pipe slides down along the adjusting rod 44 due to the rough surface of the pipe, further ensuring the normal collection of the pipe; although the cut pipes can be placed in an orderly manner through the above method, since the adjusting rod 44 needs to move continuously to satisfy the placement of the pipes in different positions in the box, the stacked pipes can only remain stable when the pipes are between multiple adjusting rods 44. When the adjusting rod 44 is separated from the stacked pipes, the stacked pipes cannot be limited and are easily broken by external forces. Collapse, for example, vibration, accidental touch, etc., which causes the neatly stacked pipes to remain messy. Therefore, in order to avoid this situation, before the pipes are placed into the box, according to the diameter of the pipes, the motor 12 53 is used to drive the threaded rod 9 54 to rotate, so that the adjusting column 21 at the right end moves. When the adjusting column 21 at the right end moves, the other adjusting columns 21 will also move due to the connecting rod 1 50 and the connecting rod 2 45, and the spacing between adjacent adjusting columns 21 will change equally until the spacing between adjacent adjusting columns 21 is close to the diameter of the pipe. Then, the motor 2 9 is used to drive the threaded rod 2 8 to rotate, so that the supporting platform 10 rises. At the same time, the electric push rod 25 is used to drive the push plate 24 to move. The push plate 24 pushes the plate body 23 to retract it into the inner cavity of the plate body 1 22, and the spring 55 is compressed until the total length of plate 1 22 and plate 2 23 is equal to the width of the box cavity. At this time, plate 1 22 and plate 2 23 can be inserted into the box cavity and fit with the bottom of the box cavity. Since the left end face of plate 1 22 on the far left is flush with one side of clamp block 2 20, plate 1 22 and plate 2 23 will also be at the left edge of the box cavity. Plate 1 22 and plate 2 23 inserted into the box will divide the placement space of the box cavity and divide the box cavity into multiple placement channels, while plate 1 22 and plate 2 23 outside the box will not play a dividing role. At this time, the adjusting rod 44 is used to place the pipes one by one and place them in sequence along the placement channels. The stacked pipes will be limited by the adjusting rod 44.The stacked pipes will be limited by the plate 1 22 and the plate 2 23. When multiple groups of stacked pipes are evenly placed in a placement channel, the adjacent pipes will have a blocking effect. Then the above operation is repeated until a sufficient number of pipes are placed in the multiple placement channels divided by the plate 1 22 and the plate 2 23. At this time, the plate 1 22 and the plate 2 23 can be driven out of the box. During the entire placement process, the stacked pipes will be limited by the adjustment rod 44, the plate 1 22, the plate 2 23, and the edge of the box and will not collapse. This avoids the situation where the stacked pipes cannot be limited and collapse when the adjustment rod 44 is separated from the stacked pipes, resulting in the neatly stacked pipes still being messy, further ensuring the neatness of the pipes in the box.
