Description

Technical Field

[0001] This invention is an integrated automated device for processing rectangular metal pipe fittings. Background Technology

[0002] Pipe fittings are parts used to connect pipes into pipelines. Based on the connection method, they can be divided into four categories: socket fittings, threaded fittings, flange fittings, and welded fittings. They are mostly made of the same material as the pipes. Examples include elbows, flanges, tees, crosses, and reducers. Elbows are used where pipes turn; flanges are used to connect pipes to each other, attached to the pipe ends; tees are used where three pipes converge; crosses are used where four pipes converge; and reducers are used where two pipes of different diameters are connected.

[0003] Automated pipe welding equipment is indispensable for pipe installation, and automation technology can completely replace manual operation. Automated pipe welding equipment is currently widely used in pipe installation.

[0004] In the general pipe fittings processing industry, punching machines are typically used for cutting, deburring machines for brushing corners, and manual or robotic welding to complete the entire product processing. This process requires multiple machines, numerous workers, and multiple material transfers, consuming a large amount of labor time, resulting in high production costs, low efficiency, and inconsistent product quality. Summary of the Invention:

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an integrated automated device for processing rectangular metal pipe fittings.

[0006] An integrated automated device for processing rectangular metal pipe fittings includes a main body, which includes a processing part, a suspension plate, a frame, a transfer mechanism, at least two arc-shaped punching mechanisms, a deburring brush mechanism, and a welding mechanism.

[0007] The processed part is a tubular object, and the upper and lower bottom surfaces of the processed part are flat rectangular shapes; the suspension plate is a rectangular metal plate bent at right angles;

[0008] The aforementioned arc-shaped punching mechanism is used to perform arc-shaped punching on both sides of the opening of the workpiece.

[0009] The aforementioned burr roller brush mechanism is used to remove burrs from the pipe opening after arc punching.

[0010] The welding mechanism is used to weld the suspension plate to the upper bottom surface of the workpiece;

[0011] The aforementioned transfer mechanism is used to move the workpiece to the processing area of ​​the processing mechanism for processing;

[0012] The frame includes a first section, a second section, and a connecting section. The first section and the second section are connected by the connecting section. The height of the second section is lower than that of the first section. The arc-cutting mechanism and the deburring brush mechanism are symmetrically distributed on both sides of the first section of the frame. The welding mechanism is symmetrically distributed on both sides of the second section of the frame. The transplanting mechanism is located in the middle of the frame and passes through the arc-cutting mechanism, the deburring brush mechanism, and the welding mechanism in sequence.

[0013] Working principle: The present invention arranges the arc punching mechanism, the burr roller brush mechanism and the welding mechanism in sequence on the frame, and realizes the movement of the workpiece in each processing mechanism through the transfer mechanism, thereby realizing automatic feeding in each processing structure.

[0014] The arc-shaped punching mechanism utilizes the downward pressure of a bench press, combined with the V-block's oblique cutting structure and the cooperation between the pressure block and the inclined surface of the slider, to change the direction of the originally vertically downward thrust, providing lateral power and pushing the slider to slide along the track.

[0015] Meanwhile, after the tube opening is punched, inward burrs are easily left, which will affect the unloading process and prevent the workpiece from being properly detached from the positioning fixture. Therefore, an unloading mechanism is added, which is connected to a push rod and a cylinder. The push rod passes through the rear end face of the punching base and is installed inside the punching base. There are two push rods, one above the other. The upper push rod pushes the upper part of the workpiece tube opening, and the lower push rod pushes the lower part of the tube opening, pushing the workpiece forward. At the same time, the cylinder connected to the floor will also pull the base plate to move the punching mechanism backward, realizing the automatic unloading of the workpiece.

[0016] Furthermore, the base plate is connected to the cylinder, and the cylinder controls the entire punching mechanism to slide back and forth along the track. When the workpiece moves to the processing position, the cylinder pushes the punching mechanism to slide forward, so that the positioning fixture is embedded in the workpiece tube opening. When the processing is completed, the cylinder pulls the entire punching mechanism to move backward, and cooperates with the unloading mechanism to make the positioning fixture disengage from the tube opening.

[0017] The burr roller brush mechanism uses a steel wire wheel to brush the burrs on the nozzle of the workpiece. The steel wire wheel is fixed to the seat through a centrally fixed shaft. At the same time, a gear is fitted on one end of the shaft, which is connected to the gear driven by the motor behind it through a belt to achieve transmission.

[0018] The welding section is divided into a feeding section and a welding section. The feeding section uses a vibratory feeder to feed the material. When the hanging plate moves to the linear feeder, it is attracted by the electromagnet above. The rotating plate is controlled to rotate by the rotating cylinder. The hanging plate is placed in the predetermined position by the lifting cylinder. Then, it is moved to the welding section by the transfer mechanism for welding.

[0019] Both ends of the rotating plate are equipped with electromagnets. Therefore, after rotating to the appropriate position, the lifting cylinder descends, which can simultaneously adsorb the hanging plate at one end and place the hanging plate at the other end. After placement, the rotating plate is rotated again to adsorb and place the plate. This process is repeated. Compared with using only one end to adsorb and place the material, working at both ends simultaneously effectively improves work efficiency.

[0020] To securely weld the suspension plate to the pipe opening, three edges of the contact surface between the suspension plate and the workpiece need to be welded. These three edges are one horizontal and two vertical. Achieving two-way welding using a single welding gun places excessively high precision requirements on the machine structure. Furthermore, this type of automatic welding mechanism has limited applicability and can only be used for workpieces with the same processing requirements.

[0021] Therefore, the present invention divides the welding work into horizontal welding and vertical welding. Horizontal welding is connected by a first translation mechanism and a lifting mechanism. The lifting mechanism is connected to the welding gun in a fixed structure. During welding, the first translation mechanism and the lifting mechanism move to a suitable position. At the same time as the welding gun is started, the first translation mechanism drives the first welding part to move horizontally to achieve horizontal pull welding.

[0022] Vertical welding is connected by a second translation mechanism and a lifting mechanism. The lifting mechanism is connected to the welding gun through a fixed structure. When the welding gun moves to the appropriate position, the second translation mechanism drives the second welding part to move in the back and forth direction to achieve vertical welding. The second welding part includes two symmetrically arranged welding guns, a second welding gun and a third welding gun, which can simultaneously weld the vertical edges on both sides of the suspension plate, thus improving work efficiency.

[0023] Meanwhile, the fixing structure includes a fixing base, a connecting sleeve assembly, and a fixing connecting rod assembly. The first welding gun, the second welding gun, and the third welding gun are connected to a connecting column that can rotate around an axis. The connecting column is fixed on a mounting block, and the mounting block has a third fixing connecting rod embedded in it. The third fixing connecting rod is connected to the second fixing connecting rod by being embedded in the third fixing sleeve. The second connecting rod is located in the second fixing sleeve. By adjusting the position of the second connecting rod in the second fixing sleeve, the height of the welding gun can be adjusted. The second fixing sleeve is connected to the fixing block of the first fixing sleeve by bolts through a fixing block. Therefore, the angle between the second fixing sleeve and the first fixing sleeve can be adjusted to change the relative angle of the second fixing connecting rod. The first fixing sleeve is fitted onto the first fixing connecting rod, and the first fixing connecting rod is installed laterally in a through hole on the side of the fixing base. By adjusting the position of the fixing sleeve, the lateral position of the welding gun can be changed. Through the fixing structure, the actual working position of the welding gun can be adjusted to adapt to different processing requirements.

[0024] The transplanting mechanism includes a first feeding mechanism, a second feeding mechanism, and a transition frame mechanism. The first feeding mechanism delivers the workpiece to the processing area of ​​the burr roller brush mechanism. The burrs at the pipe end are removed by the steel wire wheel. After removal, the first feeding mechanism continues to move the workpiece forward. When it reaches the transition frame, the working range of the first feeding mechanism ends. At this time, the workpiece is delivered to the transition frame by inertia. The workpiece slides down the transition frame onto the platform. During the process, due to the structure of the upper and lower frames, the workpiece will not roll or rotate during the descent. At the same time, the upper frame is equipped with a buffer cylinder to stop the workpiece from sliding during the descent, thus slowing down the speed and preventing it from sliding off the platform too quickly.

[0025] After the workpiece falls onto the platform, the cylinder pushes the platform forward to the predetermined position. The electromagnet above the platform descends via a lifting cylinder to attract the workpiece. Then, the platform moves backward via a cylinder, and the electromagnet descends again via a cylinder to place the workpiece into the fixture of the second feeding mechanism. The second fixture is used to limit the suspension plate. The suspension plate has a right-angle bend structure and is therefore divided into two sections. One section is connected to the upper end face of the workpiece, and the other section is suspended. The suspended section is located between the front stop and the rear stop of the second fixture. At the same time, the suspension plate is also located in the groove on the upper end face of the front stop. The groove limits the lateral freedom of the suspension plate, while the front stop and the rear stop limit the front and rear freedom. The protrusions on the inner wall of the groove limit the vertical freedom.

[0038] To prevent the workpiece from rolling off the platform due to excessive gravitational potential energy when falling from the transition frame, and to prevent the workpiece from not being able to lie flat on the platform due to friction and inertia, the transition frame includes an upper frame and a lower frame.

[0057] The lifting mechanism includes two lifting cylinders, which are symmetrically installed on both sides of the cylinder fixing plate. The lifting cylinders are perpendicular to the upper end face of the frame and face the upper end face of the frame. The second welding gun and the third welding gun are respectively connected to the lifting cylinders through the fixing mechanism.

[0058] To ensure that the workpiece does not move during processing and thus avoids errors, a limiting fixture is also included. The limiting fixture includes a first limiting fixture and a second limiting fixture. The first limiting fixture includes a mounting rod, which is positioned directly above the processing area of ​​the first welding part. The bottom of the mounting rod has two cylinders perpendicular to the mounting rod.

[0059] To fix the welding torch to the lifting cylinder, the fixing mechanism includes a fixing base.

[0060] In order to perform arc-shaped forming on the workpiece, the cutting tool is in the shape of a cuboid, the front end face of the cuboid is a convex arc-shaped surface, and the right side face of the cuboid is a concave arc-shaped surface.

[0061] Beneficial effects: Compared with the prior art, the present invention arranges the arc punching mechanism, the burr roller brush mechanism and the welding mechanism in sequence on the frame, and realizes the movement of the processed parts in each processing mechanism through the transfer mechanism, thereby realizing automatic feeding in each processing structure.

[0062] The arc-shaped punching mechanism utilizes the downward pressure of a bench press, combined with the V-block's oblique cutting structure and the cooperation between the pressure block and the inclined surface of the slider, to change the direction of the originally vertically downward thrust, providing lateral power and pushing the slider to slide along the track.

[0063] Meanwhile, after the tube opening is punched, inward burrs are easily left, which will affect the unloading process and prevent the workpiece from being properly detached from the positioning fixture. Therefore, an unloading mechanism is added, which is connected to a push rod and a cylinder. The push rod passes through the rear end face of the punching base and is installed inside the punching base. There are two push rods, one above the other. The upper push rod pushes the upper part of the workpiece tube opening, and the lower push rod pushes the lower part of the tube opening, pushing the workpiece forward. At the same time, the cylinder connected to the floor will also pull the base plate to move the punching mechanism backward, realizing the automatic unloading of the workpiece.

[0064] Furthermore, the base plate is connected to the cylinder, and the cylinder controls the entire punching mechanism to slide back and forth along the track. When the workpiece moves to the processing position, the cylinder pushes the punching mechanism to slide forward, so that the positioning fixture is embedded in the workpiece tube opening. When the processing is completed, the cylinder pulls the entire punching mechanism to move backward, and cooperates with the unloading mechanism to make the positioning fixture disengage from the tube opening.

[0065] The burr roller brush mechanism uses a steel wire wheel to brush the burrs on the nozzle of the workpiece. The steel wire wheel is fixed to the seat through a centrally fixed shaft. At the same time, a gear is fitted on one end of the shaft, which is connected to the gear driven by the motor behind it through a belt to achieve transmission.

[0066] The welding mechanism is divided into a feeding section and a welding section. The feeding section uses a vibratory feeder to feed the material. When the hanging plate moves to the linear feeder, it is attracted by the electromagnet above. The rotating plate is controlled to rotate by the rotating cylinder. The hanging plate is placed in the predetermined position by the lifting cylinder. Then, it is moved to the welding section by the transfer mechanism for welding.

[0067] Both ends of the rotating plate are equipped with electromagnets. Therefore, after rotating to the appropriate position, the lifting cylinder descends, which can simultaneously adsorb the hanging plate at one end and place the hanging plate at the other end. After placement, the rotating plate is rotated again to adsorb and place the plate. This process is repeated. Compared with using only one end to adsorb and place the material, working at both ends simultaneously effectively improves work efficiency.

[0068] To securely weld the suspension plate to the pipe opening, three edges of the contact surface between the suspension plate and the workpiece need to be welded. These three edges are one horizontal and two vertical. Achieving two-way welding using a single welding gun places excessively high precision requirements on the machine structure. Furthermore, this type of automatic welding mechanism has limited applicability and can only be used for workpieces with the same processing requirements.

[0069] Therefore, the present invention divides the welding work into horizontal welding and vertical welding. Horizontal welding is connected by a first translation mechanism and a lifting mechanism. The lifting mechanism is connected to the welding gun in a fixed structure. During welding, the first translation mechanism and the lifting mechanism move to a suitable position. At the same time as the welding gun is started, the first translation mechanism drives the first welding part to move horizontally to achieve horizontal pull welding.

[0070] Vertical welding is connected by a second translation mechanism and a lifting mechanism. The lifting mechanism is connected to the welding gun through a fixed structure. When the welding gun moves to the appropriate position, the second translation mechanism drives the second welding part to move in the back and forth direction to achieve vertical welding. The second welding part includes two symmetrically arranged welding guns, a second welding gun and a third welding gun, which can simultaneously weld the vertical edges on both sides of the suspension plate, thus improving work efficiency.

[0071] The fixing structure includes a fixing base, a connecting sleeve assembly, and a fixing connecting rod assembly. The first, second, and third welding torches are connected to a connecting column that can rotate around an axis. The connecting column is fixed to a mounting block, and a third fixing connecting rod is embedded within the mounting block. The third fixing connecting rod is connected to a second fixing connecting rod by being embedded in a third fixing sleeve. The second connecting rod is located within the second fixing sleeve, and the height of the welding torches can be adjusted by adjusting the position of the second connecting rod within the second fixing sleeve.

[0072] The second fixing sleeve is connected to the fixing block of the first fixing sleeve by bolts through the fixing block. Therefore, the angle between the second fixing sleeve and the first fixing sleeve can be adjusted to change the relative angle of the second fixing connecting rod. The first fixing sleeve is fitted onto the first fixing connecting rod, and the first fixing connecting rod is installed laterally in the through hole on the side of the fixing seat. By adjusting the position of the fixing sleeve, the lateral position of the welding gun can be changed. Through the fixing structure, the actual working position of the welding gun can be adjusted to adapt to different processing requirements.

[0073] The transplanting mechanism includes a first feeding mechanism, a second feeding mechanism, and a transition frame mechanism. The first feeding mechanism delivers the workpiece to the processing area of ​​the burr roller brush mechanism. The burrs at the pipe end are removed by the steel wire wheel. After removal, the first feeding mechanism continues to move the workpiece forward. When it reaches the transition frame, the working range of the first feeding mechanism ends. At this time, the workpiece is delivered to the transition frame by inertia. The workpiece slides down the transition frame onto the platform. During the process, due to the structure of the upper and lower frames, the workpiece will not roll or rotate during the descent. At the same time, the upper frame is equipped with a buffer cylinder to stop the workpiece from sliding during the descent, thus slowing down the speed and preventing it from sliding off the platform too quickly.

[0074] After the workpiece falls onto the platform, the cylinder pushes the platform forward to the predetermined position. The electromagnet above the platform descends via a lifting cylinder to attract the workpiece. Then, the platform moves backward via a cylinder, and the electromagnet descends again via a cylinder to place the workpiece into the fixture of the second feeding mechanism. The second fixture is used to limit the suspension plate. The suspension plate has a right-angle bend structure and is therefore divided into two sections. One section is connected to the upper end face of the workpiece, and the other section is suspended. The suspended section is located between the front stop and the rear stop of the second fixture. At the same time, the suspension plate is also located in the groove on the upper end face of the front stop. The groove limits the lateral freedom of the suspension plate, while the front stop and the rear stop limit the front and rear freedom. The protrusions on the inner wall of the groove limit the vertical freedom. Attached Figure Description

[0136] In this embodiment, the cutting tool is in the shape of a cuboid, with the front end face of the cuboid being a convex arc surface and the right side face of the cuboid being a concave arc surface.

[0137] Instructions for use: Place the workpiece 69 on the inclined hopper. The workpiece falls from the inclined hopper to the vertical hopper. The transfer mechanism moves the workpiece 69 to the processing position of the arc-shaped punching mechanism 2. Then, the cylinder 28 pushes the base plate to move the arc-shaped punching mechanism 2 forward as a whole. The end of the workpiece 69 is fitted onto the positioning fixture 38. At the same time, the bench press operates.

[0138] The pressure block presses down, and the oblique cutting mechanism of the pressure block and the slider converts the downward pushing force into an oblique force and provides a lateral pushing force, pushing the slider to slide laterally, so that the cutter cuts the tube opening. After the cutting is completed, the slider is reset by the elastic reset member. At the same time, the cylinder 28 of the ejection mechanism moves forward, and the first push rod and the second push rod push the workpiece 69 out. The cylinder 28 connected to the base plate pulls the punching mechanism to move backward to realize the ejection.

[0139] Afterwards, the first feeding mechanism sends the workpiece 69 to the processing area of ​​the burr roller brush mechanism 4. The burr at the pipe end is removed by the steel wire wheel. After the removal is completed, the first feeding mechanism continues to move the workpiece 69 forward. When it reaches the transition frame 5, the working range of the first feeding mechanism ends. At this time, the workpiece 69 is sent to the transition frame 5 by inertia. The workpiece 69 slides down the transition frame onto the platform 27. During the process, due to the structure of the upper and lower frames 25, the workpiece 69 will not roll or rotate during the descent. At the same time, the upper frame 24 is equipped with a buffer cylinder 28, which makes the workpiece 69 stop sliding first during the descent, so that the speed is slowed down and it is prevented from sliding off the platform 27 too fast.

[0140] After the workpiece 69 falls onto the platform 27, the cylinder 28 pushes the platform 27 forward to a predetermined position. The electromagnet 50 above the platform 27 descends via the lifting cylinder 47 to attract the workpiece 69. Subsequently, the platform 27 moves backward via the cylinder 28, and the electromagnet 50 descends again via the cylinder 28 to place the workpiece 69 into the fixture of the second feeding mechanism. The second fixture is used to limit the suspension plate 70. The suspension plate 70 has a right-angle bend structure and is therefore divided into two sections. One section is connected to the upper end face of the workpiece 69, and the other section is suspended. The suspended section is located between the front stop 21 and the rear stop 22 of the second fixture. At the same time, the suspension plate 70 is also located in the groove on the upper end face of the front stop 21. The groove limits the lateral freedom of the suspension plate 70, while the front stop 21 and the rear stop 22 limit the front and rear freedom. The protrusions on the inner wall of the groove limit the vertical freedom.

[0141] Furthermore, the suspension plate 70 is fed through the feeding part of the welding mechanism 6. The electromagnet 50 moves up and down through the lifting mechanism 53 to attract the suspension plate 70. Then, the suspension plate 70 is positioned above the workpiece 69 by the rotating cylinder. The suspension plate 70 is then placed on the workpiece 69 by the lifting cylinder. After that, the workpiece 69 and the suspension plate 70 are sent to the first welding part and the second welding part for welding reinforcement by the second feeding mechanism. Finally, the workpiece 69 and the suspension plate 70 are sent into the slide frame 7 by the second feeding mechanism and slide into the unloading bin 8.

[0142] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
