Description

Technical Field

[0001] The invention belongs to the field of other metal processing machinery manufacturing, in particular to a cutting device for special equipment processing. Background Art

[0002] Forklifts, off-road tourist sightseeing vehicles, and push-top trucks are special equipment. These vehicles often use a large number of L-shaped high-strength welded metal pipes during the manufacturing and equipment process. During the production of L-shaped high-strength welded metal pipes, the ends of the two sets of metal pipes need to be cut at a 45-degree angle. The cutting process usually uses a laser cutting device, which is efficient and highly precise. In addition, this type of laser cutting device used to manufacture special equipment belongs to other metal processing machinery manufacturing.

[0003] The patent with announcement number CN118180663B discloses a laser cutting equipment for processing special vehicle parts, including two groups of support seats, each of which is provided with an installation box, and each of which is provided with multiple groups of clamping and positioning mechanisms for fixing pipe fittings. A laser cutting mechanism is provided on the top of the installation box, and the clamping and positioning mechanism includes a clamping drive group, a positioning column, an internal support assembly and other structures. The laser cutting mechanism includes a guide rail, a support leg, a sliding seat, a laser cutting machine and other structures. This scheme cooperates with the laser cutting mechanism through the clamping and positioning mechanism. When performing oblique integrated cutting on multiple pipe fittings, it also realizes integrated grinding of the cutting edge, removes burrs on the oblique cut of the pipe fitting, further improves the quality of the cutting edge of the pipe fitting, and also improves the joint quality and effect when the two pipe fittings are welded into an L shape, ensuring a firm connection.

[0004] In the above scheme, the laser cutting machine cuts the end of the pipe into a 45-degree angle at one time. This cutting method causes the surface of the pipe to be heated unevenly, and local areas of the pipe may overheat due to heat accumulation, resulting in reduced cutting quality, such as uneven incisions and pipe deformation, resulting in a decrease in product yield. For this reason, the present invention provides a cutting device for special equipment processing. Summary of the Invention

[0007] By rotating the pipe, the laser cutter cuts along the surface of the pipe end, making the surface of the pipe end heat more evenly, which not only improves product quality but also reduces the defective rate of the product.

[0008] Preferably, a feeding mechanism is provided in front of the rotating mechanism, the feeding mechanism includes a fixed frame, the fixed frame is opposite to the fixed ring frame, a storage box fixedly mounted on the fixed frame, a pushing column movably mounted between the storage box and the fixed frame, a screw sleeve fixedly sleeved on one end of the pushing column, a screw screwed with the screw sleeve, a first arc groove is provided at the lower end of the storage box, a second arc groove is provided at the upper end of the fixed frame, the second arc groove and the first arc groove form a material channel, the pushing column is plugged into the material channel, one end of the screw is rotatably connected to the fixed frame, and the other end of the screw is rotatably connected to the support frame, a second motor for driving the screw is installed on the support frame, and the support frame is fixedly mounted on the fixed frame;

[0009] During the loading process, the new pipe fittings push the processed pipe fittings out of the discharge chute, so that the discharge and removal are carried out simultaneously, which not only improves the automation rate of the device, but also improves the efficiency of pipe fitting replacement, thereby improving the efficiency of pipe fitting processing.

[0010] Preferably, the feeding mechanism also includes a blocking mechanism, which includes a receiving plate, the receiving plate is movably mounted below the fixed frame, a blocking plate fixedly mounted on one end of the receiving plate for blocking the pipe fitting, two sets of side plates fixedly mounted on the other end of the receiving plate, the upper end of the receiving rod is fixedly connected to the screw sleeve, the lower end of the receiving rod is provided with a fixed shaft, guide grooves are provided on the side plates, both ends of the fixed shaft are respectively located in the two sets of guide grooves, two sets of through holes are provided on the receiving plate, the through holes are slidably connected to the guide posts, the upper ends of the guide posts are fixedly connected to the fixed frame, and the guide grooves are composed of a first transverse groove, an oblique groove, and a second transverse groove;

[0011] The end of the fixed shaft continues to slide along the oblique groove, causing the side plate, the receiving plate and the baffle to move upward together until the end of the fixed shaft slides into the second transverse groove.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. By rotating the pipe, the laser cutter cuts along the surface of the pipe end, making the surface of the pipe end heat more evenly, which not only improves product quality but also reduces the defective rate of the product.

[0014] 2. When a group of pipe fittings is cut, the fixation of the pipe fitting is first released, and then the second motor drives the lead screw to rotate, so that the screw sleeve drives the pushing column to move along the material channel toward the feed port. At the same time, the pushing column pushes the pipe fitting along the material channel into the feed port, and enters the discharge trough through the feed port. As the pipe fitting enters the discharge trough, the pipe fitting will push the cut pipe fitting to move along the discharge trough, so that the cut pipe fitting is pushed out of the discharge trough, and the new pipe fitting is pushed into the discharge trough. Therefore, during the loading process, the new pipe fitting pushes the processed pipe fitting out of the discharge trough, so that the discharge and material collection are carried out simultaneously, which not only improves the automation rate of the device, but also improves the pipe replacement efficiency, thereby improving the pipe processing efficiency.

[0015] 3. When the pipe fitting enters the discharge chute, the moving screw sleeve drives the receiving rod to move together with the fixed shaft. At the same time, the end of the fixed shaft first slides along the first transverse groove. When the end of the fixed shaft slides to the intersection of the first transverse groove and the oblique groove, the processed pipe fitting is just pushed out of the discharge chute. The end of the fixed shaft continues to slide along the oblique groove, causing the side plate together with the receiving plate and the baffle to move upward until the end of the fixed shaft slides into the second transverse groove. The baffle will stop the pipe fitting from continuing to move. Therefore, the baffle can block the inertial movement of the pipe fitting, thereby ensuring that the pushing column can quickly push the pipe fitting into the discharge chute, thereby ensuring the efficiency of pipe fitting processing.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] Example 1: Figures 1 to 4 As shown, a cutting device for special equipment processing described in an embodiment of the present invention includes an XYZ transport mechanism 1, a laser cutter 2 is provided on the XYZ transport mechanism 1, a rotating mechanism 3 for rotating a pipe 5 is provided in front of the laser cutter 2, the rotating mechanism 3 includes a fixed ring frame 301, the fixed ring frame 301 is located in front of the laser cutter 2, a rotating seat 302 rotatably installed in the fixed ring frame 301, a gear ring 303 fixedly mounted on the end of the rotating seat 302, the gear ring 303 meshing with a gear 304, a first motor 305 fixedly mounted on the fixed ring frame 301 for driving the gear 304, two groups of cylinders 306 symmetrically mounted on both sides of the fixed ring frame 301, a roller 307 rotatably mounted on the output end of the cylinder 306, a receiving plate 308 on one side close to the roller 307, and a receiving plate 308 on one side. Six groups of movable parts 309 are connected, one end of the movable part 309 is provided with a U-shaped spring piece 310, a pressure plate 311 is provided under the movable part 309, the movable part 309 is plugged into the pressure plate 311, and a discharge trough 21 for placing the pipe fitting 5 is provided in the middle of the rotating seat 302, and six groups of rectangular grooves 22 are provided around the discharge trough 21. The movable part 309 and the pressure plate 311 are both slidably connected to the discharge trough 21, and a feed port 81 is provided in the middle of the receiving plate 308. The feed port 81 is opposite to the discharge trough 21, and oblique slide grooves 11 are provided on both sides of the pressure plate 311. A pin shaft 91 is provided at the lower end of the movable part 309, and the two ends of the pin shaft 91 are respectively located in the two groups of oblique slide grooves 11. One side of the U-shaped spring piece 310 is fixedly connected to the movable part 309, and the other side of the U-shaped spring piece 310 is fixedly connected to the inner wall of the rectangular groove 22. A rubber pad 12 is provided on the pressure plate 311.

[0029] Specifically, the XYZ transport mechanism 1 is composed of three sets of synchronous belt drive mechanisms, which enable the laser cutter 2 to move freely in the XYZ axis direction. The inner diameter of the feed port 81 is equal to the outer diameter of the pipe 5, and the inner diameter of the discharge trough 21 is larger than the outer diameter of the pipe 5. In the initial state, the inner diameter of the area enclosed by the six sets of pressure plates 311 is larger than the outer diameter of the pipe 5. When the pipe 5 needs to be cut, the pipe 5 is inserted into the discharge trough 21 from the feed port 81, and then the corresponding rollers 307 are pushed by two sets of cylinders 306 to squeeze the receiving plate 308. The receiving plate 308 drives the six sets of movable parts 309 to slide along the corresponding rectangular groove 22, and the movable parts 309 stretch the U-shaped spring piece 310. At the same time, the movable parts 309 drive the pin shaft 91 to slide along the corresponding oblique slide groove 11, so that the six sets of pressure plates 311 together with the rubber pad 12 move toward the pipe 5. Until the pipe 5 is moved and clamped between the six groups of pressure plates 311, the laser cutter 2 is transported to the top of the end of the pipe 5 by the XYZ conveying mechanism 1, and then the end of the pipe 5 is cut by the laser cutter 2. At the same time, the first motor 305 drives the gear 304 to rotate, and the gear 304 drives the rotating seat 302 to rotate together with the pipe 5 through the gear ring 303. The roller 307 rolls along the receiving plate 308, and cooperates with the XYZ conveying mechanism 1 to move the laser cutter 2 in multiple directions. The laser cutter 2 cuts along the end surface of the pipe 5 until the end of the pipe 5 is cut into a 45-degree angle. Compared with the prior art, by rotating the pipe 5, the laser cutter 2 cuts along the end surface of the pipe 5, so that the end surface of the pipe 5 is heated more evenly, which not only improves the product quality, but also reduces the defective rate of the product.

[0030] like Figure 5 and Figure 6 As shown, a feeding mechanism 4 is provided in front of the rotating mechanism 3, and the feeding mechanism 4 includes a fixed frame 401, the fixed frame 401 is opposite to the fixed ring frame 301, a storage box 402 fixedly mounted on the fixed frame 401, a pushing column 403 movably mounted between the storage box 402 and the fixed frame 401, a screw sleeve 405 fixedly sleeved on one end of the pushing column 403, a screw screw 404 screwed with the screw sleeve 405, a first arc groove 4011 is provided at the lower end of the storage box 402, a second arc groove 4021 is provided at the upper end of the fixed frame 401, the second arc groove 4021 and the first arc groove 4011 form a material channel, the pushing column 403 is plugged into the material channel, one end of the screw screw 404 is rotatably connected to the fixed frame 401, and the other end of the screw screw 404 is rotatably connected to the support frame 406, a second motor 407 for driving the screw screw 404 is installed on the support frame 406, and the support frame 406 is fixedly mounted on the fixed frame 401.

[0031] Specifically, the material channel is opposite to the feed port 81, and the inner diameter of the material channel is equal to the inner diameter of the feed port 81. After processing a group of pipe fittings 5, the pipe fittings 5 ​​need to be taken down before the next group can be placed for processing. The taking and placing of the pipe fittings 5 ​​wastes a lot of time, which reduces the processing efficiency of the pipe fittings 5. Therefore, when a group of pipe fittings 5 ​​is cut, the fixation of the pipe fittings 5 ​​is first released, and then the second motor 407 drives the lead screw 404 to rotate, so that the screw sleeve 405 drives the pushing column 403 to move along the material channel toward the feed port 81. At the same time, the pushing column 403 pushes the pipe fittings 5 ​​along the material channel into the feed port 81, and enters the discharge trough 21 through the feed port 81. As the pipe fittings 5 ​​are cut, the lead screw 404 is driven to rotate by the second motor 407, so that the screw sleeve 405 drives the pushing column 403 to move along the material channel toward the feed port 81. At the same time, the pushing column 403 pushes the pipe fittings 5 ​​into the feed port 81 along the material channel, and enters the discharge trough 21 through the feed port 81. After entering the discharge trough 21, the pipe fitting 5 will push the cut pipe fitting 5 to move along the discharge trough 21, so that the cut pipe fitting 5 is pushed out of the discharge trough 21, and the new pipe fitting 5 is pushed into the discharge trough 21. During this process, the pushing column 403 sliding along the material channel blocks the pipe fitting 5 located in the storage box 402, so that the pipe fitting 5 cannot fall until the pushing column 403 is withdrawn from the material channel. Under the action of gravity, the pipe fitting 5 will automatically fall into the material channel. Therefore, during the loading process, the new pipe fitting 5 will push the processed pipe fitting 5 out of the discharge trough 21, so that the discharge and material collection are carried out simultaneously, which not only improves the automation rate of the device, but also improves the replacement efficiency of the pipe fitting 5, thereby improving the processing efficiency of the pipe fitting 5.

[0032] Example 2: Figures 7 to 9 As shown, in contrast to Example 1, another embodiment of the present invention is as follows: the feeding mechanism 4 further includes a blocking mechanism 408, which includes a receiving plate 4081, which is movably mounted below the fixing frame 401, a baffle 4082 fixedly mounted on one end of the receiving plate 4081 for blocking the pipe 5, two sets of side plates 4083 fixedly mounted on the other end of the receiving plate 4081, and a screw sleeve 4 fixedly connected to the upper end of the receiving rod 4084. 05. A fixed shaft 4086 is provided at the lower end of the receiving rod 4084, and a guide groove 4085 is provided on the side plate 4083. Both ends of the fixed shaft 4086 are respectively located in the two groups of guide grooves 4085. Two groups of through holes 811 are provided on the receiving plate 4081. The through holes 811 are slidably connected to the guide pillars 812. The upper ends of the guide pillars 812 are fixedly connected to the fixing frame 401. The guide groove 4085 consists of a first transverse groove 851, an oblique groove 852, and a second transverse groove 853.

[0033] Specifically, the pushing pin 403 pushes the pipe 5 into the discharge trough 21 too fast, and the fast-moving pipe 5 generates inertia. When the pushing pin 403 stops pushing the pipe 5, the pipe 5 will continue to move under the action of inertia, causing the position of the pipe 5 in the discharge trough 21 to deviate. If the speed at which the pipe 5 enters the discharge trough 21 is reduced, although the inertia is solved, the replacement rate of the pipe 5 is reduced, thereby reducing the processing efficiency of the entire pipe 5. Therefore, during the process of the pipe 5 entering the discharge trough 21, the moving screw sleeve 405 drives the receiving rod 4084 to move together with the fixed shaft 4086, and at the same time, the end of the fixed shaft 4086 first slides along the first transverse groove 851. When the fixed shaft 4086 When the end slides to the intersection of the first transverse groove 851 and the oblique groove 852, the processed pipe 5 is just pushed out of the discharge trough 21, and the end of the fixed shaft 4086 continues to slide along the oblique groove 852, so that the side plate 4083 moves upward together with the receiving plate 4081 and the baffle 4082. During this process, the through hole 811 on the receiving plate 4081 slides upward along the guide column 812 until the end of the fixed shaft 4086 slides into the second transverse groove 853. The baffle 4082 will block the pipe 5 from continuing to move. Therefore, the baffle 4082 can block the inertial movement of the pipe 5, thereby ensuring that the pushing column 403 can quickly push the pipe 5 into the discharge trough 21, thereby ensuring the processing efficiency of the pipe 5.

[0034] Working principle: Insert the pipe 5 into the discharge trough 21 from the feed port 81, and then push the corresponding roller 307 to squeeze the receiving plate 308 through the two groups of cylinders 306. The receiving plate 308 drives the six groups of movable parts 309 to slide along the corresponding rectangular groove 22, and the movable parts 309 stretch the U-shaped spring pieces 310. At the same time, the movable parts 309 drive the pins 91 to slide along the corresponding oblique slide grooves 11, so that the six groups of pressure plates 311 together with the rubber pads 12 move toward the pipe 5 until the pipe 5 is clamped between the six groups of pressure plates 311. The laser cutter 2 is moved to the top of the end of the pipe 5 by the XYZ transport mechanism 1. The end of the pipe 5 is then cut by the laser cutter 2. At the same time, the first motor 305 drives the gear 304 to rotate. The gear 304 drives the rotating seat 302 to rotate together with the pipe 5 through the gear ring 303. The roller 307 rolls against the receiving plate 308. In cooperation with the XYZ transport mechanism 1, the laser cutter 2 is moved in multiple directions. The laser cutter 2 cuts against the surface of the end of the pipe 5 until the end of the pipe 5 is cut into a 45-degree angle.

[0035] After a group of pipe fittings 5 ​​is cut, the fixation of the pipe fitting 5 is first released, and then the second motor 407 drives the lead screw 404 to rotate, so that the screw sleeve 405 drives the pushing column 403 to move along the material channel toward the feeding port 81, and at the same time, the pushing column 403 pushes the pipe fitting 5 along the material channel into the feeding port 81, and enters the discharge chute 21 through the feeding port 81. As the pipe fitting 5 enters the discharge chute 21, the pipe fitting 5 will push the cut pipe fitting 5 to move along the discharge chute 21, so that the cut pipe fitting 5 is pushed out of the discharge chute 21, and the new pipe fitting 5 is pushed into the discharge chute 21. In this process, the pushing column 403 sliding along the material channel blocks the pipe fitting 5 in the storage box 402, so that the pipe fitting 5 cannot fall until the pushing column 403 is withdrawn from the material channel. Under the action of gravity, the pipe fitting 5 will automatically fall into the material channel;

[0036] When the pipe fitting 5 enters the discharge trough 21, the moving screw sleeve 405 drives the receiving rod 4084 to move together with the fixed shaft 4086. At the same time, the end of the fixed shaft 4086 first slides along the first transverse groove 851. When the end of the fixed shaft 4086 slides to the intersection of the first transverse groove 851 and the oblique groove 852, the processed pipe fitting 5 is just pushed out of the discharge trough 21. The end of the fixed shaft 4086 continues to slide along the oblique groove 852, causing the side plate 4083 to move upward together with the receiving plate 4081 and the baffle 4082. During this process, the through hole 811 on the receiving plate 4081 slides upward along the guide column 812 until the end of the fixed shaft 4086 slides into the second transverse groove 853. The baffle 4082 will block the pipe fitting 5 from continuing to move.
