Description

Technical Field

[0001] The invention relates to the technical field of groove cutting, and in particular to a universal groove cutting intelligent device. Background Art

[0002] Bevel cutting is an important process in the welding preparation process, which is mainly used to ensure the quality and strength of the welded joint. The welding edge of the workpiece is processed and treated to form a certain angle or shape to provide sufficient filling space for the welding material and ensure that the two pieces of metal can be fully fused. When welding round tubes vertically, the existing general-purpose automatic laser or plasma cutting machine will be used for bevel processing. The cutting head moves according to the preset trajectory of the program, and the pipe is rotated in the forward or reverse direction according to the preset program to cooperate with the movement of the cutting head to cut out the appropriate bevel shape.

[0003] When pipe fittings are welded vertically, it is often necessary to cut multiple grooves on one pipe fitting, and then cut grooves on the ends of other pipe fittings (generally an X-shaped groove is cut at this time). The pipe fittings after the pipe end treatment are butt-jointed with the corresponding grooves for welding. When multiple grooves are cut continuously on the pipeline, a large amount of slag will splash around. These slags will fall into the pipeline through the adjacent grooves (the cut pieces of waste will fall out of the grooves as the pipe fittings rotate). Especially when flame or plasma cutting is used, these slags will adhere to the inner wall of the pipeline to a certain extent. After cutting, the inner wall of the pipe fitting needs to be cleaned, which is troublesome. If covering materials are used manually to cover the formed grooves, it will be detrimental to efficient automated processing.

[0004] Therefore, in response to the above problem, if the cut waste is used as the covering material of the formed bevel groove, it can not only avoid manual intervention in the automated cutting process, but also do not require the use of additional covering materials. The cost is relatively low and the protection effect on the inside of the pipe is good. Therefore, a device can be designed to prevent pieces of waste from falling out of the bevel groove when multiple bevels are cut continuously, thereby reducing the possibility of slag splashing into the pipe. Summary of the invention

[0005] In order to overcome the problem that when performing continuous multi-groove cutting on a pipe fitting, the splashed slag will fall into the pipe fitting through the adjacent groove grooves, making it inconvenient to clean.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. Through the arrangement of the retaining component and the first inflation component, during the cutting point transfer process of the cutting machine, it automatically extends to block the groove formed by the previous cutting point, preventing the scrap pieces from falling out of the corresponding groove. In this way, when cutting at the next cutting point, a large amount of molten slag will not splash into the adjacent groove, achieving a good internal protection effect for the pipe fittings.

[0018] 2. Through the arrangement of the steering component, the retaining component can be controlled to rotate to the side of the pipe fitting away from the groove. In this way, when performing the first groove cutting on the pipe fitting, the retaining component will not block the cutting point.

[0019] 3. The retaining component automatically expands and contracts with the movement of the cutting machine. When in the contracted state, the retaining component has a small structural size and occupies little space.

[0020] 4. The buffer component provided on the retaining component can elastically support the scrap pieces in the groove, avoiding the scrap pieces separated from the groove due to the rotation of the pipe fitting during the cutting process and hitting the retaining component, causing damage to the retaining component.

[0021] 5. The retaining component that can elastically support the scrap pieces through the buffer component can leave a certain distance from the outer wall of the pipe fitting. Compared with the form of closely abutting against the outer wall of the pipe fitting to block the scrap, there will be no frictional resistance during the rotation of the pipe fitting, and the pipe fitting rotates more smoothly.

[0022] 6. Through the cooperation of the second driving component and the knocking component, during continuous multi-point cutting, the scrap in the formed groove can be continuously knocked, and by vibrating, it can be avoided that the molten slag in the gap between the groove and the corresponding scrap is melted again due to heat, resulting in the scrap adhering to the pipe fitting again.

[0023] 7. Through the cooperation of the knocking component and the buffer component, the scrap will not fall out of the groove during vibration, maximizing the effect of blocking and protecting the groove.

[0024] 8. Through the third inflation component and the air outlet component, a linkage is formed with the movement of the knocking component. When knocking the waste, an air flow can be blown from the bottom up through the gap between the waste and the corresponding groove, blowing off the remaining slag, which can prevent the slag from falling into the pipe fitting through the gap. In addition, it can also reduce the situation where the slag is heated and melted again during continuous cutting. BRIEF DESCRIPTION OF THE DRAWINGS

A first inflation assembly is installed on the track frame 1. When the moving machine 2 moves along the track frame 1, gas flows between the first inflation assembly and the retaining assembly. The first inflation assembly is used to control the shortening or elongation of the retaining assembly; a first driving assembly is installed on the auxiliary deflection assembly, a follow-up assembly is installed on the output end of the first driving assembly, a second inflation assembly is installed on the follow-up assembly, and a buffer assembly is movably installed in the retaining assembly. The first driving assembly is used to drive the follow-up assembly to move along the axis direction of the pipe fitting.

The second inflation assembly is used to control the movement of the buffer assembly in the retaining assembly. The pipe fitting includes a main pipe 19, and a plurality of bevel cutting points are provided on the main pipe 19. The cutting machine cuts out a bevel groove 20 at the corresponding bevel cutting point; when gas flows into the retaining assembly from the first inflation assembly, the retaining assembly elongates; when gas flows from the retaining assembly into the first inflation assembly, the retaining assembly shortens; when gas flows into the retaining assembly from the second inflation assembly, the buffer assembly approaches the outer wall of the main pipe 19; when gas flows from the retaining assembly into the second inflation assembly, the buffer assembly moves away from the outer wall of the main pipe 19;The auxiliary deflection assembly includes a No. 1 motor 501 mounted on the bracket 4, a deflection sleeve 502 mounted on the output end of the No. 1 motor 501, a clamping module 503 arranged in the deflection sleeve 502, a guide rod 504 fixedly connected at one end to the deflection sleeve 502, and an end block 505 fixedly connected at the other end of the guide rod 504.

The end of the pipe fitting can be clamped by a cylinder or a stepper motor in actual application, so that the pipe fitting can rotate with the deflection sleeve 502. The pipe fitting can be a main pipe 19 or a branch pipe 18. The method for processing the main pipe 19 is to perform continuous cutting processing at multiple groove cutting points on it. The method for processing the branch pipe 18 is to cut its pipe end, generally cutting it into an X-shaped groove. The cutting machine in this solution can use a laser cutting machine 3 or a flame cutting machine. According to two sets of preset programs, the main pipe 19 and the branch pipe 18 are respectively subjected to universal cutting processing. The steering component, the support component, the landing component and the first drive component are mainly for the main pipe 19. The processing of the main pipe 19 plays a corresponding role), the deflection sleeve 502 is driven by the No. 1 motor 501 in the auxiliary deflection assembly to drive the main pipe 19 to rotate forward or reverse according to the preset program (synchronously, the cutting machine drives the cutting head to move along the established route on the main pipe 19 for cutting according to the preset program), the mobile machine 2 (in actual application, existing linear motors and other equipment can be used) drives the cutting machine to move along the track frame 1 to move the cutting point.

The other end of the second return spring 1303 is connected in the air cavity 705. When the gas in the second air hood 1201 flows into the air cavity 705, the plunger 1301 and the buffer head 1302 approach the main pipe 19;When the gas in the air chamber 705 flows into the second air hood 1201, the plunger 1301 and the buffer head 1302 move away from the main pipe 19. During the process of the moving machine 2 controlling the cutting machine to move from the previous groove cutting point to the next groove cutting point, the industrial computer synchronously sends a signal to the control unit of the fourth motor 1001, causing the second screw 1002 to rotate. With the guiding function of the guide rod 504, the sliding sleeve base 1101 is controlled to move synchronously (in the N1 direction) to the previous groove cutting point. By the relative movement of the end plate 1102 and the end block 505, the second air hood 1201 is squeezed, and the gas in the second air hood 1201 flows into the air chamber 705 through the second gas pipeline 1202. The air pressure in the air chamber 705 increases, pushing the plunger 1301 to move, and making the buffer head 1302 (which can be made of high-temperature resistant flexible materials such as glass wool) approach the main pipe 19 (the groove 20 and the waste therein) until the buffer head 1302 abuts against the waste (when the waste is impacted, part of the gas in the air chamber 705 will flow back into the second air hood 1201, causing a small radial expansion of the second air hood 1201). When the sliding sleeve base 1101 moves in the N2 direction, the gas in the air chamber 705 flows back into the second air hood 1201. Under the action of the second return spring 1303, the plunger 1301 drives the buffer head 1302 away from the pipe fitting.;

[0046] Please refer to Figures 1-4 、 Figure 7 、 Figures 9-10 and Figure 14, a second driving component is installed on the follower component, a knocking component is movably connected to the follower component, the input end of the knocking component is connected to the output end of the second driving component, and the second driving component is used to drive the knocking component to approach or move away from the inner wall of the pipe fitting; a third air inflation component and an air outlet component are installed in the follower component, and the knocking component is used to control the flow of gas between the third air inflation component and the air outlet component. When the knocking component approaches the inner wall of the pipe fitting, the gas flows from the third air inflation component into the air outlet component; when the knocking component moves away from the inner wall of the pipe fitting, the gas flows from the air outlet component into the third air inflation component. When the follower component moves to the corresponding groove cutting point, the second driving component is started to control the knocking component to swing reciprocally and impact the waste in the corresponding groove 20 (when the groove is cut by the cutting machine, part of the slag formed by metal melting will remain in the gap between the groove 20 and the waste. In subsequent multiple thermal cutting processes, the newly generated high-temperature area may reheat the slag that has cooled but not completely solidified, increasing its fluidity, resulting in their re-adhesion between the waste and the groove 20 again, making the waste block re-connect to the pipe. Moreover, there is roughness between the groove and the waste block, and it is easier for the slag to adhere locally after remelting. Therefore, it is necessary to set up a knocking component. During the multi-point continuous groove cutting process, the waste in the groove 20 at the groove cutting point that has been cut is frequently knocked, and the melting and adhesion of the slag are relieved through vibration). When hitting the waste, through the elastic buffering effect of the buffer component, the waste vibrates in the groove 20 (when the waste block vibrates, a gap will be generated between it and the groove 20, and the slag is easily stuck in the gap. Continuous impact vibration will cause the slag to fall into the main pipe 19 through this gap. Therefore, it is necessary to set up an air outlet component to blow air intermittently, and through the gap between the waste and the groove 20, part of the slag is blown away).

[0047] Please refer to Figures 2-4 , Figure 7 , Figures 9-10 and Figure 14, the second driving component includes a fifth motor 1401 installed on the sliding sleeve base 1101 and a linkage main gear 1402 installed on the output end of the fifth motor 1401. The fifth motor 1401 is used to drive the linkage main gear 1402 to rotate. The input end of the knocking component is connected to the linkage main gear 1402, and the linkage main gear 1402 is used to drive the knocking component to approach or move away from the inner wall of the main pipe 19; the knocking component includes a knocking rod 1501 movably connected in the receiving groove 1103, a linkage secondary gear 1502 fixedly connected to the knocking rod 1501 and a wing rod 1503, and a pressing plate 1504 installed on the wing rod 1503. The linkage secondary gear 1502 meshes with the linkage main gear 1402. The wing rod 1503 is movably connected in the track groove 1104. A cavity communicating with the track groove 1104 is provided in the sliding sleeve base 1101. The pressing plate 1504 is arranged in the cavity. The linkage main gear 1402 drives the knocking rod 1501, the wing rod 1503 and the pressing plate 1504 to rotate through the linkage secondary gear 1502. The pressing plate 1504 is used to control the flow of gas between the third inflating component and the air outlet component; the third inflating component includes a third air hood 1601 installed on the pressing plate 1504 and a third air pipe 1602 with one end connected to the third air hood 1601. The other end of the third air pipe 1602 is connected to the air outlet component, and gas flows between the third air hood 1601 and the air outlet component; when the knocking rod 1501 approaches the inner wall of the main pipe 19, the gas in the third air hood 1601 flows into the air outlet component; when the knocking rod 1501 moves away from the inner wall of the main pipe 19, the gas in the air outlet component flows into the third air hood 1601; the air outlet component includes an air ring 1701 installed on the sliding sleeve base 1101 and a plurality of air holes 1702 opened on the air ring 1701. The other end of the third air pipe 1602 is connected to the air ring 1701, and gas flows into or out of the air ring 1701 through the air holes 1702; when the knocking rod 1501 approaches the inner wall of the main pipe 19, gas flows out of the air ring 1701 through the air holes 1702; when the knocking rod 1501 moves away from the inner wall of the main pipe 19, gas flows into the air ring 1701 through the air holes 1702. The fifth motor 1401 outputs power (outputs power in a positive and negative direction cycle) to the linkage main gear 1402, and transmits the power to the linkage secondary gear 1502 through the linkage main gear 1402, controlling the knocking rod 1501 to swing reciprocally (driving the wing rod 1503 and the pressing plate 1504 to move in the same direction together). When the knocking rod 1501 swings towards the inner wall of the main pipe 19, it will approach the waste material in the corresponding groove 20, causing vibration by impact. When the knocking rod 1501 approaches the waste material and the pressing plate 1504 moves accordingly, it cooperates with the inner wall of the cavity of the sliding sleeve base 1101 to exert a squeezing effect on the third air hood 1601, causing the gas therein to flow into the air ring 1701 through the third air pipe 1602 and blow out from the air holes 1702 (towards the groove 20. At this time, the waste material is impacted by the knocking rod 1501, and the gap between the waste material and the groove 20 expands, facilitating the exposure and blowing out of the slag).

[0048] Please refer to Figure 15 When machining the branch pipe 18, similarly, one end of the branch pipe 18 is installed on the auxiliary deflection assembly. The first motor 501 in the auxiliary deflection assembly drives the deflection sleeve 502 to drive the pipe fitting to rotate forward or backward according to a preset program. Synchronously, the cutting machine drives the cutting head to move along a predetermined path at the end of the branch pipe 18 for cutting to form an X-shaped groove adapted to the groove 20 of the groove opening.

[0049] Working principle: Insert one end of the main pipe 19 into the deflection sleeve 502, bite and fix the end of the main pipe 19 through the clamping module 503. Start the cutting machine to drive the cutting head to move along a predetermined path at the first groove cutting point on the main pipe 19 for cutting. At the same time, the first motor 501 drives the deflection sleeve 502 to drive the main pipe 19 to rotate forward or backward according to a preset program, so that a groove 20 is formed at the first groove cutting point on the main pipe 19, and a whole piece of waste material remaining in the groove 20 is generated;

[0050] Then, the moving machine 2 drives the cutting machine to move along the track frame 1 to the position of the second groove cutting point. During the movement, the first air hood 901 is compressed, and the gas therein flows into the stop rod 702 through the first air pipe 902, so that two adjacent sleeve rods 704 move relative to each other, and the stop rod 702 gradually extends. At the same time, the second motor 603 outputs power to the gear ring 601 through the transmission gear 604, and drives the stop rod 702 to rotate to the first groove cutting point through the rotation of the gear ring 601. Moreover, the third motor 801 outputs power to the output bevel gear 802, and controls the input bevel gear 803 and the first screw rod 804 to rotate through the output bevel gear 802. The rotating first screw rod 804 controls the base 701 to move along the guide groove 602, so that the stop rod 702 approaches the outer wall of the main pipe 19 to prevent the waste material in the groove 20 at the first groove cutting point from falling out;

[0051] When the cutting machine moves to the second groove cutting point, the fourth motor 1001 outputs power to the second screw rod 1002. The rotating second screw rod 1002 controls the sliding sleeve base 1101 to move to the first groove cutting point. The second air hood 1201 is compressed, and the gas therein flows into the corresponding air chamber 705 through the second air pipe 1202, so that the plunger 1301 in the air chamber 705 moves, driving the buffer head 1302 to abut against the waste material at the first groove cutting point;

[0052] When the cutting machine cuts at the second bevel cutting point, the fifth motor 1401 starts, and the power is transmitted to the linkage secondary gear 1502 through the linkage main gear 1402, controlling the knocking rod 1501 to reciprocally impact the corresponding waste material. The vibration of the waste material is caused by the impact, and the pressing plate 1504 follows the movement, exerting an extrusion effect on the third air hood 1601, causing the gas therein to flow into the air ring 1701 through the third air pipe 1602 and blow out from the air holes 1702, passing through the gap between the bevel groove 20 and the waste material to blow away the remaining slag.
