Abstract
Description
Technical Field
[0001] This invention relates to the field of welded pipe processing equipment technology, specifically to a high-efficiency welded pipe deburring and breaking equipment suitable for the machinery industry. Background Technology
[0002] In the large-scale production process of welded pipe (also known as welded steel pipe), in order to ensure the accuracy of the end dimensions and facilitate subsequent connection or welding, the pipe ends usually need to be cut by flattening, chamfering and other processes. This process will inevitably produce metal cutting residues that curl inward or rise up in the end area of the inner wall of the welded pipe, which is commonly referred to as "internal burrs". If these burrs are not removed, they will seriously affect the performance and appearance quality of the welded pipe.
[0003] Currently, the industry commonly uses automated deburring equipment based on the air-blowing principle. The basic workflow and structure of such equipment are as follows: First, a stepping conveyor mechanism (such as a servo motor-driven roller conveyor or grippers) precisely and individually transports the welded pipes to a specific "blowing station." Upon arrival, a clamping cylinder installed at the station actuates, pressing and positioning the welded pipe from the outside to prevent movement during the blowing process. Then, an air-blowing pipe (usually a slender metal tube) connected to a high-pressure air source moves forward and extends into the processed end of the welded pipe, driven by another drive mechanism (such as a cylinder or motor), until it approaches the burr area. At this point, high-pressure gas (usually compressed air) is ejected instantaneously or continuously from the air-blowing pipe, and the powerful airflow impact blows away the burrs adhering to the pipe wall. The blown-out burrs are discharged from the pipe opening with the airflow direction and eventually fall into a mobile collection trolley or simple chip collection box located below the equipment.
[0004] Although the above technical solutions have achieved the mechanization of the deburring process, they have obvious defects in actual long-term operation: due to the lack of an "instant and effective pre-treatment" step for the blown burrs, the blown burrs are often long strips or flakes, large in volume and long in length, and easily get tangled in the collection device, making cleaning difficult, causing equipment blockage, affecting the efficiency of continuous operation, and requiring frequent shutdowns for cleaning, which increases manual maintenance costs and safety hazards. Summary of the Invention
[0005] To address the problems existing in the background technology, the present invention provides a welded pipe deburring and breaking machine, which integrates a burr collection and crushing mechanism to mechanically crush the burrs the moment they are blown out, transforming them from difficult-to-handle "long strips" into easily conveyed and cleaned "granular" shapes, thus achieving continuous operation, greatly improving production efficiency and equipment utilization. Moreover, the device has a high degree of integration, a compact structure, and is easy to integrate into existing production lines.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] This invention provides a welded pipe deburring and breaking machine, including a frame. The frame has a clamping and blowing mechanism at both ends along its length for clamping one end of the welded pipe and blowing high-pressure gas into the pipe, and a burr collecting and crushing mechanism for receiving and crushing burrs blown out from the other end of the welded pipe. The frame has a stepping feed mechanism in the middle for clamping the welded pipe and conveying it to the clamping and blowing mechanism, and a transfer drive mechanism for driving the burr collecting and crushing mechanism to move along the length of the frame. A chip conveyor is provided directly below the frame for connecting to the discharge port of the burr collecting and crushing mechanism.
[0008] The burr collection and crushing mechanism includes a waste collection box. The bottom of the waste collection box is slidably mounted on the frame and can be moved along the length of the frame by a transfer drive mechanism. A crushing component is installed inside the waste collection box. An installation groove is provided on the side of the waste collection box facing the clamping and blowing mechanism. A first upper clamp and a first lower clamp are rotatably mounted at the upper and lower positions inside the installation groove, respectively. Under the drive of the drive cylinder, the distal ends of the first upper clamp and the first lower clamp can be opened and closed to clamp and position one end of the welded pipe. A waste collection pipe that can be connected to the end of the welded pipe is provided inside the first upper clamp and the first lower clamp. The end of the waste collection pipe extends inward into the waste collection box.
[0009] The above technical solution is adopted:
[0010] The frame is equipped with a clamping and blowing mechanism and a burr collection and crushing mechanism at both ends, a stepping feeding mechanism and a transfer drive mechanism in the middle, and a chip conveyor at the bottom. The above layout structure forms a clear linear process flow (feeding-clamping-blowing-collecting and crushing-chip removal), with a compact structure, the shortest logistics path, high space utilization, and easy integration into existing production lines.
[0011] Through structural design and optimization of the burr collection and crushing mechanism, its structure is compact, which not only achieves clamping of one end of the welded pipe, but also hides the waste collection pipe between the first upper clamp and the first lower clamp, and links with the clamping action to form a burr collection inlet at the end of the welded pipe that is exactly connected to the welding end.
[0012] A further improvement is that both the first lower clamp and the first upper clamp are plate-shaped structures. The upper side of the first lower clamp has multiple parallel limiting grooves. The lower side of the first upper clamp is equipped with inverted conical waste collection pipes corresponding to the limiting grooves. The outer side of the first upper clamp is provided with protrusions that correspond to the ends of the limiting grooves. When the first upper clamp and the first lower clamp are closed by the drive cylinder, the protrusions cooperate with the ends of the limiting grooves to clamp and position one end of the welded pipe, and the waste collection pipe is housed in the limiting groove.
[0013] By engaging the limiting groove end of the first lower clamp with the protrusion at the end of the first upper clamp, the outer side of the welded pipe end is positioned and clamped. In addition, the limiting groove on the upper side of the first lower clamp can also provide a storage point for the waste collection tube. When the outer ends of the first upper clamp and the first lower clamp are joined together to clamp the welded pipe, an inverted conical structure is formed between them. The inverted conical waste collection tube is precisely hidden in the limiting groove on the upper side of the first lower clamp. This structural design is ingenious and reasonable. The structure of the inverted conical waste collection tube can not only match the structure of the first upper and lower clamps well, but its flared end design can also tightly surround the end of the welded pipe, which is conducive to efficiently capturing the burrs and airflow ejected from the welded pipe, playing a converging and guiding role, and improving the collection efficiency.
[0014] A further improvement is that the shape and size of the limiting groove match the shape and size of the waste collection pipe, and the outer end of the limiting groove of the first lower clamp has a V-shaped structure.
[0015] The outer end of the limiting groove of the first lower clamp is set with a V-shaped structure, which cooperates with the protrusion at the end of the first upper clamp to provide stable and flexible three-point positioning and clamping of the outer wall of the welded pipe, adapting to a certain range of pipe diameter changes. At the same time, the clamp and structural design can also provide a collection point for the waste collection pipe to collect and properly dock (to dock with the end of the welded pipe).
[0016] A further improvement is that a rectangular mounting frame is provided at the mounting slot of the waste collection box, and the ends of the inner sides of the first lower clamp and the first upper clamp are respectively embedded into the rectangular mounting frame. A driving cylinder is driven and connected to the opposite side of the first upper clamp and the first lower clamp. The driving cylinder is installed on the outer side of the waste collection box. A connecting member is also provided on the opposite side of the first upper clamp and the first lower clamp, and the inner end of the connecting member is rotatably installed on the outer side of the waste collection box.
[0017] The opening and closing of the first lower clamp and the first upper clamp are achieved through the cooperation of a rectangular mounting frame, a drive cylinder, and a rotating connector. The rectangular mounting frame provides a stable mounting reference and motion guide for the clamps. The drive cylinder drives the clamps to rotate around the pivot at the end of the connector, ensuring sufficient and controllable clamping force between the first lower clamp and the first upper clamp. The rotating structure at the end of the connector, in conjunction with the drive cylinder, enables reliable opening and closing movements between the first lower clamp and the first upper clamp.
[0018] A further improvement is that the length of the rectangular mounting frame is slightly greater than the length of the first upper and lower clamps, the width of the rectangular mounting frame is slightly greater than the sum of the thicknesses of the first upper and lower clamps, and the first upper clamp and the first lower clamp are provided with an avoidance angle on the side facing each other.
[0019] By designing the size and shape of the rectangular mounting frame, as well as the "avoidance angle," when the first upper clamp and the first lower clamp are driven by the cylinder to close, their inner ends fit together to the maximum extent while allowing the end of the waste collection pipe to pass through. This forms a maximum sealing structure with the rectangular mounting frame, preventing mechanical interference during the closing process of the first upper clamp and the first lower clamp, ensuring the smooth operation, and also preventing debris from splashing out from the rectangular mounting frame when the crushing components inside the waste collection box are operating.
[0020] A further improvement is that the front end of the waste collection pipe is an inverted conical structure that extends to near the avoidance angle, and the end of the waste collection pipe is cylindrical that extends backward from the avoidance angle into the interior of the waste collection box.
[0021] The waste collection pipe is made of flexible hose, which has a certain degree of elasticity and can better adapt to the closing operation of the first upper clamp and the first lower clamp.
[0022] A further improvement is that the waste collection box is provided with an inverted conical feeding element inside, the large end of the feeding element is fitted into the mounting groove near the waste collection box, and the small end of the feeding element is located near the crushing component.
[0023] The feeder further guides and gathers the burrs initially collected by the waste collection pipe to the inlet of the crushing component, ensuring that the burrs can smoothly enter the crushing area and avoid being dispersed and accumulated inside the box, thereby improving crushing efficiency and processing reliability.
[0024] A further improvement is that the clamping and blowing mechanism includes a bracket, on which a second upper clamp and a second lower clamp are mounted side by side. The vertical distance between the second upper clamp and the second lower clamp is adjustable, and the second upper clamp and the second lower clamp can move in the lateral direction. The bracket is also equipped with a first blowing component and a second blowing component, and both the first blowing component and the second blowing component can move in the lateral direction, the vertical direction, and the front-back direction.
[0025] The adjustable mounting structure of the second upper clamp and the second lower clamp enables precise and stable clamping of the welded pipe end. In conjunction with the clamp at the collection end, it ensures that the welded pipe maintains straightness and stability during the purging process.
[0026] Both the first and second air-blowing components are multi-directionally movable, allowing for precise adjustment of the position and angle of the air-blowing ends. This ensures optimal insertion into welded pipes of different diameters, targeting burr-generating areas for improved purging. Furthermore, they can sequentially blow air onto multiple welded pipes held side-by-side by a clamp, increasing work efficiency. Additionally, the two air-blowing components are used for step-by-step purging (such as coarse and fine blowing), ensuring a cleaner interior for the welded pipes.
[0027] A further improvement is that the blowing ends of the first blowing assembly and the second blowing assembly are located on the side of the second upper clamp and the second lower clamp away from the burr collection and crushing mechanism.
[0028] A further improvement is that the second upper clamp and the second lower clamp are each provided with multiple positioning grooves facing one side, and the cross-section of the positioning grooves is a V-shaped structure.
[0029] The V-groove has a self-centering effect, which can better adapt to and accommodate cylindrical welded pipes of different diameters, provide a more uniform clamping force distribution, reduce the risk of pipe deformation, and enhance clamping stability.
[0030] Compared with the prior art, the present invention has the following beneficial effects:
[0031] (1) This invention creatively integrates burr collection, instant crushing and automatic chip removal functions into one unit. The whole machine adopts a linear layout, and the functional modules are orderly distributed along the frame. The collection and crushing mechanism is vertically connected to the chip removal machine below, which makes the structure compact, occupies a small area, and is easy to integrate into existing production lines. The equipment integrates a full-process functional unit such as step feeding, bidirectional clamping and positioning, high-pressure blowing, collection and crushing and automatic chip removal. Through the coordinated work of the movable burr collection and crushing mechanism (driven by the transfer drive mechanism) and the multi-directional adjustable clamping and blowing mechanism, it can automatically adapt to welded pipes of different lengths and diameters, complete precise alignment, stable clamping and efficient blowing, realize fully automated precision operation, and greatly improve production efficiency.
[0032] (2) By setting up a dedicated burr collection and crushing mechanism, the long strips of burrs blown out of the welded pipe are mechanically crushed into short particles that are easy to transport at the moment of discharge, thus achieving efficient collection and cleaning. This eliminates the problems of burr entanglement, accumulation, and blockage of the collection device in the traditional method, greatly reducing the difficulty of cleaning and the frequency of equipment maintenance, and realizing the cleanliness and continuity of the production process.
[0033] (3) The waste collection pipe adopts a unique structural design to optimize the material path and ensure efficient collection. Specifically, it adopts an integrated collection pipe with an inverted cone shape at the front end and a cylindrical shape at the rear end. The inverted cone opening can tightly surround the end of the welded pipe, efficiently capturing and converging the scattered burrs and airflow. The cylindrical section establishes a stable conveying channel to ensure that the burrs are smoothly introduced into the crushing zone. The first upper and lower clamps clamp one end of the welded pipe by cooperating with the V-shaped limiting groove and the protrusion. In addition, the limiting groove on the upper side of the first lower clamp can also provide a storage point for the waste collection tube. When the outer ends of the first upper clamp and the first lower clamp are put together to clamp the welded pipe, they form an inverted conical structure. The inverted conical waste collection tube is just hidden in the limiting groove on the upper side of the first lower clamp. This structure is ingenious and reasonable. The structure of the inverted conical waste collection tube can not only match the structure of the first upper and lower clamps well, but also its end flaring design can tightly surround the end of the welded pipe, which is conducive to efficiently capturing the burrs and airflow ejected from the welded pipe, playing a converging and guiding role, and improving the collection efficiency. The inverted conical feeder set inside the waste collection box further guides the burrs to the crushing component, avoiding the dispersion and accumulation inside the box.
[0034] (4) The distance between the second upper and lower clamps of the air-blowing mechanism is adjustable, and it is equipped with first and second air-blowing components that can move in multiple directions. It can accurately adjust the air-blowing position and angle to ensure that the high-pressure gas is accurately applied to the burr area of the inner wall of the welded pipe, and the blowing effect is more thorough. The secondary air-blowing design further ensures the cleanliness of the inside of the welded pipe. Attached Figure Description

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0050] An embodiment of the present invention discloses a welded pipe deburring and breaking machine, such as... Figure 1 and Figure 2 As shown, the machine includes a frame 1. The frame 1 is provided with a clamping and blowing mechanism 3 at both ends along the length direction for clamping one end of the welded pipe and blowing high-pressure gas into the welded pipe, and a burr collecting and crushing mechanism 2 for receiving and crushing burrs blown out from the other end of the welded pipe. The frame 1 is provided with one or more stepping feeding mechanisms 4 for clamping the welded pipe and conveying it to the clamping and blowing mechanism 3, and a transfer driving mechanism 5 for driving the burr collecting and crushing mechanism 2 to move along the length direction of the frame 1. The frame 1 is provided with a chip conveyor 6 directly below the frame 1 for connecting to the discharge port of the burr collecting and crushing mechanism 2.
[0051] The burr collection and crushing mechanism 2 includes a waste collection box 201. The bottom of the waste collection box 201 is slidably mounted on the frame 1 and can be moved along the length of the frame 1 by the transfer drive mechanism 5. A crushing component 203 is installed inside the waste collection box 201. An installation groove 206 is opened on the side of the waste collection box 201 facing the clamping and blowing mechanism 3. A first upper clamp 208 and a first lower clamp 212 are rotatably mounted at the upper and lower positions inside the installation groove 206, respectively. Driven by the driving cylinder 215, the first upper clamp 208 and the first lower clamp 212 can open and close at their distal ends to clamp and position one end of the welded pipe. The first upper clamp 208 and the first lower clamp 212 are equipped with a waste chip collection pipe 214 that can be connected to the end of the welded pipe. The end of the waste chip collection pipe 214 extends inward into the waste chip collection box 201. The bottom of the waste chip collection box 201 is an inverted cone structure and has a discharge port. The chip conveyor 6 is located directly below the discharge port.
[0052] The frame 1 has a clamping and blowing mechanism 3 and a burr collection and crushing mechanism 2 at both ends, a stepping feeding mechanism 4 and a transfer drive mechanism 5 in the middle, and a chip conveyor 6 at the bottom. The above layout forms a clear linear process flow (feeding-clamping-blowing-collecting and crushing-chip removal), with a compact structure, shortest material path, high space utilization, and easy integration into existing production lines. Through the structural design and optimization of the burr collection and crushing mechanism 2, its structure is compact, which not only achieves clamping of one end of the welded pipe, but also hides the waste chip collection pipe 214 between the first upper clamp 208 and the first lower clamp 212, and is linked with the clamping action to form a burr collection inlet at the end of the welded pipe that is exactly connected to the welding end.
[0053] In specific operation, the middle part of the welded pipe is first fixed by the stepping feed mechanism 4, and then the end of the welded pipe is clamped and limited by the first upper clamp 208 and the first lower clamp 212. At this time, the flared end of each waste collection pipe 214 is exactly connected with the corresponding end of the welded pipe. The welded pipe is moved by the transfer drive mechanism 5 and the stepping feed mechanism 4 until the other end of the welded pipe is located at the clamping mechanism position of the clamping air blowing mechanism 3. The other end of the welded pipe is clamped and fixed by adjusting the clamping mechanism of the clamping air blowing mechanism 3, and the crushing component 203 is turned on. Then the first air blowing and the second air blowing are performed, so as to realize the full closed-loop burr treatment process of "positioning clamping - two high-pressure blowing - in-situ collection - instant crushing - automatic chip removal".
[0054] Among them, such as Figure 2 and Figure 3As shown, both the first lower clamp 212 and the first upper clamp 208 are plate-shaped structures. The upper side of the first lower clamp 212 has multiple parallel limiting grooves 213. The lower side of the first upper clamp 208 is equipped with inverted conical waste collection pipes 214 corresponding to the limiting grooves 213. The outer side of the first upper clamp 208 is provided with protrusions 211 that correspond to the ends of the limiting grooves 213. When the first upper clamp 208 and the first lower clamp 212 are closed by the drive cylinder 215, the protrusions 211 and the ends of the limiting grooves 213 cooperate to clamp and position one end of the welded pipe, and the waste collection pipes 214 are housed in the limiting grooves 213. The positioning and clamping of the outer side of the welded pipe end is achieved by the engagement of the limiting groove 213 on the first lower clamp 212 with the protrusion 211 on the end of the first upper clamp 208. Additionally, the limiting groove 213 on the upper side of the first lower clamp 212 provides a storage location for the waste collection tube 214. When the outer ends of the first upper clamp 208 and the first lower clamp 212 are joined together to clamp the welded pipe, an inverted conical structure is formed between them. The inverted conical waste collection tube 214 is precisely hidden within the limiting groove 213 on the upper side of the first lower clamp 212, ensuring that the end of the waste collection tube 214 is precisely aligned with the end of the welded pipe held by the clamps. This structural design is ingenious and reasonable. The inverted conical waste collection tube 214 not only matches the structure of the first upper and lower clamps well, but its flared end design tightly surrounds the end of the welded pipe, facilitating the efficient capture of burrs and airflow ejected from the welded pipe, thus acting as a convergence and guide, and improving collection efficiency.
[0055] In a specific embodiment, the shape and size of the limiting groove 213 match the shape and size of the waste collection tube 214, and the outer end of the limiting groove 213 of the first lower clamp 212 has a V-shaped structure. The outer end of the limiting groove 213 of the first lower clamp 212 is set as a V-shaped structure, which cooperates with the protrusion 211 at the end of the first upper clamp 208 to provide stable and flexible three-point positioning and clamping of the outer wall of the welded pipe, adapting to a certain range of pipe diameter changes. At the same time, the clamp's structural design also provides a collection point for the waste collection tube 214 to be stored and properly docked (docked with the end of the welded pipe).
[0056] Preferably, a rectangular mounting frame 207 is provided at the mounting slot 206 of the waste collection box 201. The inner ends of the first lower clamp 212 and the first upper clamp 208 are respectively embedded into the rectangular mounting frame 207. A drive cylinder 215 is driven and connected to the opposite side of the first upper clamp 208 and the first lower clamp 212. The drive cylinder 215 is installed on the outer side of the waste collection box 201. A connector 210 is also provided on the opposite side of the first upper clamp 208 and the first lower clamp 212. The inner end of the connector 210 is rotatably installed on the outer side of the waste collection box 201. The opening and closing of the first lower clamp 212 and the first upper clamp 208 are achieved through the cooperation of the rectangular mounting frame 207, the drive cylinder 215, and the rotatable connector 210. The rectangular mounting frame 207 provides a stable mounting reference and motion guide for the clamp. The drive cylinder 215 drives the clamp to rotate around the pivot at the end of the connector 210, ensuring that a sufficient and controllable clamping force is formed between the first lower clamp 212 and the first upper clamp 208. The rotating structure at the end of the connector 210 cooperates with the drive cylinder 215 to realize reliable opening and closing movements between the first lower clamp 212 and the first upper clamp 208.
[0057] More preferably, the length of the rectangular mounting frame 207 is slightly greater than the length of the first upper and lower clamps, the width of the rectangular mounting frame 207 is slightly greater than the sum of the thicknesses of the first upper and lower clamps, and the first upper clamp 208 and the first lower clamp 212 are provided with a clearance angle 209 facing each other on one side. By designing the size and shape of the rectangular mounting frame 207 and the "clearance angle 209", when the first upper clamp 208 and the first lower clamp 212 are closed by the drive cylinder 215, the inner ends of the first upper clamp 208 and the first lower clamp 212 fit together to the maximum extent while forming a passage for the end of the waste collection pipe 214. This forms a maximum sealing structure with the rectangular mounting frame 207, which will not cause mechanical interference to the closing process of the first upper clamp 208 and the first lower clamp 212, ensuring the operation process, and also preventing the debris from splashing out from the rectangular mounting frame 207 when the crushing component 203 inside the waste collection box 201 is operating.
[0058] The front end of the waste collection pipe 214 is an inverted conical structure, extending to near the clearance angle 209. The end of the waste collection pipe 214 is cylindrical, extending rearward from the clearance angle 209 into the interior of the waste collection box 201. The waste collection pipe 214 is made of flexible hose, which has a certain degree of elasticity and can better adapt to the closing operation of the first upper clamp 208 and the first lower clamp 212.
[0059] The waste collection bin 201 is equipped with an inverted conical feed guide 202. The larger end of the feed guide 202 is fitted into the mounting groove 206 near the waste collection bin 201, while the smaller end is located near the crushing assembly 203. This feed guide 202 further guides and gathers the burrs initially collected by the waste collection pipe 214 to the inlet of the crushing assembly 203, ensuring that the burrs can smoothly enter the crushing area and avoid scattering and accumulating inside the bin, thereby improving crushing efficiency and processing reliability.
[0060] Among them, the crushing component 203 adopts a conventional structural component with crushing function, such as Figure 4 As shown, the structure consists of an upper crushing roller 204 and a lower crushing roller 205. The distance between the upper crushing roller 204 and the lower crushing roller 205 is adjustable to adjust the degree of crushing. The upper crushing roller 204 is driven by a motor, and the upper crushing roller 204 and the lower crushing roller 205 are connected by gear transmission.
[0061] The chip conveyor 6 can be a chain-plate chip conveyor or a screw chip conveyor. In a specific embodiment, such as... Figure 5 As shown, a chain plate type chip conveyor is used to receive the crushed burrs and transport them by belt line 601 to the waste chip collection bin 602.
[0062] Among them, such as Figure 6As shown, the clamping and blowing mechanism 3 includes a bracket 301. A second upper clamp 302 and a second lower clamp 303 are mounted side-by-side on the bracket 301. The vertical distance between the second upper clamp 302 and the second lower clamp 303 is adjustable, and both the second upper clamp 302 and the second lower clamp 303 can move laterally. A first blowing assembly 304 and a second blowing assembly 305 are also mounted on the bracket 301, and both the first blowing assembly 304 and the second blowing assembly 305 can move laterally, vertically, and forward / backward. The adjustable mounting structure of the second upper clamp 302 and the second lower clamp 303 (specifically, they can be moved vertically and laterally by a lifting drive assembly and a lateral drive assembly) achieves precise and stable clamping of the welded pipe end. In conjunction with the clamp at the collection end, it ensures that the welded pipe maintains straightness and stability during the blowing process. Both the first air blowing assembly 304 and the second air blowing assembly 305 can move in multiple directions (using existing multi-dimensional drive components to drive the air blowing assemblies in multi-dimensional movement; the air blowing assemblies can adopt existing structural components capable of controlling the blowing of high-pressure gas, such as a combination structure of high-pressure gas source + air blowing pipe + air blowing end). The position and angle of the air blowing ends in the first air blowing assembly 304 and the second air blowing assembly 305 can be precisely adjusted to optimally extend into the interior of welded pipes of different diameters, aligning with the burr-generating area, optimizing the blowing effect, and enabling sequential blowing of multiple welded pipes held by a fixture side-by-side, improving work efficiency. Furthermore, the use of two air blowing assemblies for step-by-step blowing (such as coarse blowing and fine blowing) ensures a cleaner interior for the welded pipes.
[0063] In a specific embodiment, the air-blowing ends of the first air-blowing assembly 304 and the second air-blowing assembly 305 are located on the side of the second upper clamp 302 and the second lower clamp 303 opposite to the burr collection and crushing mechanism 2, facilitating the movement of the air-blowing ends of the first air-blowing assembly 304 and the second air-blowing assembly 305. The second upper clamp 302 and the second lower clamp 303 each have multiple positioning grooves facing one side, and the cross-section of the positioning grooves is a V-shaped structure. The V-shaped groove has a self-centering effect, which can better adapt to and accommodate cylindrical welded pipes of different diameters, providing a more uniform clamping force distribution, reducing the risk of pipe deformation, and enhancing clamping stability.

[0064] This invention creatively integrates burr collection, instant crushing, and automatic chip removal into one unit. The entire machine adopts a linear layout, with functional modules orderly distributed along the frame 1. The collection and crushing mechanism is vertically connected to the chip conveyor 6 below, resulting in a compact structure, small footprint, and easy integration into existing production lines. The equipment integrates a full range of functional units, including stepping feed, bidirectional clamping and positioning, high-pressure blowing, collection and crushing, and automatic chip removal. Through the coordinated operation of the movable burr collection and crushing mechanism 2 (driven by the transfer drive mechanism 5) and the multi-directionally adjustable clamping and blowing mechanism 3, it can automatically adapt to welded pipes of different lengths and diameters, achieving precise alignment, stable clamping, and efficient blowing, realizing fully automated and precise operation, and significantly improving production efficiency. By setting up a dedicated burr collection and crushing mechanism 2, the long strip-shaped burrs blown out of the welded pipe are mechanically crushed into short particles that are easy to transport, achieving efficient collection and cleaning. This eliminates the problems of burr entanglement, accumulation, and blockage of the collection device in traditional methods, greatly reducing the difficulty of cleaning and the frequency of equipment maintenance, and realizing a clean and continuous production process. The waste collection pipe 214 adopts a unique structural design to optimize the material path and ensure efficient collection. Specifically, it adopts an integrated collection pipe with an inverted conical front end and a cylindrical rear end. The inverted conical opening can tightly surround the end of the welded pipe, efficiently capturing and converging the scattered burrs and airflow. The cylindrical section establishes a stable conveying channel to ensure that the burrs are smoothly introduced into the crushing zone. The first upper and lower clamps clamp one end of the welded pipe by cooperating with the V-shaped limiting groove 213 and the protrusion 211. In addition, the limiting groove 213 on the upper side of the first lower clamp 212 can also provide a storage point for the waste collection tube 214. When the outer ends of the first upper clamp 208 and the first lower clamp 212 are put together to clamp the welded pipe, they form an inverted conical structure. The inverted conical waste collection tube 214 is just hidden in the limiting groove 213 on the upper side of the first lower clamp 212. This structure is ingenious and reasonable. The structure of the inverted conical waste collection tube 214 can not only match the structure of the first upper and lower clamps well, but also its end flaring design can tightly surround the end of the welded pipe, which is conducive to efficiently capturing the burrs and airflow ejected from the welded pipe, playing a converging and guiding role, and improving the collection efficiency. The inverted conical feeder 202 set inside the waste collection box 201 further guides the burrs to the crushing component 203, avoiding the dispersion and accumulation inside the box. The spacing between the second upper and lower clamps of the air-blowing mechanism 3 is adjustable, and it is equipped with first and second air-blowing components 305 that can move in multiple directions. This allows for precise adjustment of the air-blowing position and angle, ensuring that the high-pressure gas is accurately applied to the burr area on the inner wall of the welded pipe, resulting in a more thorough cleaning effect. The secondary air-blowing design further guarantees the cleanliness of the inside of the welded pipe.
