Description

Technical Field

[0001] This invention belongs to the field of machining technology, specifically relating to a pipe cutting and chamfering device and method. Background Technology

[0002] Hollow tubing is widely used in various products, such as steel cables in automobiles, where hollow tubing is often used as an outer sheath. Depending on the product requirements, hollow tubing may require multiple processing steps, such as cutting and chamfering. Existing equipment with these functions typically cuts the hollow tubing to a specified length and then transfers it to the next processing station. This design suffers from numerous components, a complex structure, and a large footprint. For example, such equipment often requires multiple transfer units to move the tubing between different stations, increasing complexity. If processing is needed at both ends of the tubing, even more transfer units are required, further complicating the equipment. Therefore, simplifying the structure of tubing cutting and chamfering equipment is a key technical challenge that needs to be addressed. Summary of the Invention

[0003] The purpose of this invention is to provide a pipe cutting and chamfering device and method, which has the advantages of simple structure and small footprint.

[0004] To achieve the aforementioned objectives, the technical solution adopted by this invention is as follows: In one aspect, an embodiment of this application provides a pipe cutting and chamfering device, including a frame, a feeding assembly, two processing assemblies, a cutting assembly, and a clamping assembly. The feeding assembly is movably connected to the frame along a first direction and outputs the processed part along a second direction, the first direction being perpendicular to the second direction. The two processing assemblies are spaced apart on the frame along the first direction, with their processing sides facing each other along the second direction. One processing assembly's processing side faces the feeding assembly along the second direction, while the other processing assembly is arranged with the feeding assembly along the first direction. The cutting assembly is positioned between the two processing assemblies along the first direction. Along the second direction, the clamping assembly is positioned between the two processing assemblies and is movably connected to the frame along the first direction.

[0005] In some embodiments, the feeding assembly includes a first base, an extension tube, a guide tube, and a conveying component. The first base is movably connected to the frame along a first direction, the extension tube is connected to the first base, and the axial direction of the extension tube extends along the first direction. The guide tube is connected to the first base, and the axial direction of the guide tube extends along the first direction. The extension tube and the guide tube are spaced apart along a second direction. The conveying component is disposed between the extension tube and the guide tube.

[0006] In some embodiments, a clamping cylinder is provided at the output end of the guide tube.

[0007] In some embodiments, the conveying component includes two movable plates, which are movably connected to a first base in a direction perpendicular to the axial direction of the guide tube. The movable plates are rotatably equipped with a plurality of pulleys, which are spaced apart along the axial direction of the guide tube, and a conveyor belt is wound around the outer periphery of the plurality of pulleys.

[0008] In some embodiments, the processing components include an outer chamfering component, an inner chamfering component, and a deburring component, wherein the outer chamfering component, the inner chamfering component, and the deburring component of the two processing components are arranged along a first direction.

[0009] In some embodiments, the outer end chamfering component includes a second base, an adjusting seat, a rotating seat, and a grinding wheel. The second base is movably connected to the frame along a second direction. The adjusting seat is rotatably connected to the second base, and the rotation axis of the adjusting seat is parallel to the second direction. The adjusting seat includes two opposing arms, each arm having a first fixing hole and a second fixing hole. The second fixing hole is arc-shaped, and its center is located at the axis of the first fixing hole. The rotating seat is disposed between the two arms and has two mating holes, which are respectively opposite to the first and second fixing holes. The grinding wheel is rotatably connected to the rotating seat.

[0010] In some embodiments, the cutting assembly includes a drive unit, a cutting wheel, a base plate, and a pressing unit. The drive unit is movably connected to the frame in a third direction and includes a rotating end. The cutting wheel is connected to the rotating end. The base plate is connected to the frame and configured such that when the workpiece moves to the cutting station, the workpiece is placed on the base plate. The pressing unit is disposed above the base plate and is movably connected to the frame in a third direction.

[0011] In some embodiments, the clamping assembly includes a body, two clamping arms, and two grippers. The body is movably connected to the frame along a first direction. Each clamping arm includes two spaced-apart first connecting portions and a second connecting portion connecting the two first connecting portions. The body is disposed between the two first connecting portions, with the first connecting portions rotatably connected to the body, and the second connecting portions and the body in clearance fit. The two grippers are respectively connected to the second connecting portions of the two clamping arms.

[0012] In some embodiments, the frame is provided with a feeding ramp along a first direction, the feeding ramp is provided on one side of the frame, and the feeding ramp is provided with a notch for accommodating a clamping component.

[0013] On the other hand, this application provides a pipe cutting and chamfering method, applied to the pipe cutting and chamfering equipment in the above embodiments, including:

[0014] The workpiece is conveyed along the second direction by the feeding assembly, so that the first end of the workpiece can be located on the processing side of the processing assembly that is opposite to the feeding assembly;

[0015] The feeding assembly moves along the first direction, and the first end of the workpiece is processed by the processing assembly.

[0016] The feeding assembly continues to move along the first direction until it reaches the cutting assembly. The feeding assembly then continues to convey the workpiece along the second direction until the discharge length of the workpiece reaches the set value.

[0017] The movable clamping assembly clamps the workpiece, and the cutting assembly cuts the workpiece.

[0018] The clamping assembly continues to move along the first direction, and the second end of the workpiece is processed by the processing assembly which is spaced apart from the feeding assembly along the first direction.

[0019] The present invention has the following beneficial effects:

[0020] 1. The feeding assembly serves both as a material feeder and a means of moving the workpiece. Compared to traditional processing equipment, it reduces the number of times the workpiece needs to be transferred and the number of intermediate transfer components required, thereby significantly simplifying the equipment structure.

[0021] 2. By reducing the number of times the workpiece needs to be transferred, the positional error of the workpiece is reduced.

[0022] 3. The feeding assembly fixes the workpiece, allowing one end to be processed. The feeding assembly then moves to the cutting assembly, which cuts the pipe. Simultaneously, the clamping assembly holds the cut workpiece and moves it, allowing the other end to be processed. The overall processing flow is efficient and fast. Furthermore, this structure ensures that the clamping point is close to the end of the workpiece being processed, improving processing stability and guaranteeing processing quality.

[0023] 4. By controlling the feeding of the feeding component, the length of the workpiece can be adjusted when the cutting component cuts the workpiece. That is, in a batch of processing, workpieces of different lengths can be processed without adjusting the equipment.

[0024] 5. The cost of expanding and modifying the equipment is very low. Specifically, the processing components can include multiple processing parts. When adding or removing processing parts, only the travel of the feeding component and the clamping component needs to be adjusted. Attached Figure Description

Detailed Implementation

[0039] 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. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0040] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0041] On one hand, this application provides a pipe cutting and chamfering device, including a frame 1, a feeding assembly 3, two processing assemblies 2, a cutting assembly 4, and a clamping assembly 8. The feeding assembly 3 is movably connected to the frame 1 along a first direction, and outputs the processed part 7 along a second direction, the first direction being perpendicular to the second direction. The two processing assemblies 2 are spaced apart on the frame 1 along the first direction, with their processing sides facing each other along the second direction. One processing assembly 2 has its processing side facing the feeding assembly 3 along the second direction, while the other processing assembly 2 is arranged with the feeding assembly 3 along the first direction. The cutting assembly 4 is positioned between the two processing assemblies 2 along the first direction. The clamping assembly 8 is positioned between the two processing assemblies 2 along the second direction and is movably connected to the frame 1 along the first direction.

[0042] The first direction can be the direction shown by the X-axis in the figure, and the second direction can be the direction shown by the Y-axis in the figure.

[0043] The processed part 7 in this embodiment can be a hollow tube or a similar slender strip product.

[0044] The processing side of processing component 2 refers to the side on which the workpiece 7 is processed.

[0045] In this embodiment, the two processing components 2 can be arranged as follows: one processing component 2 and the feeding component 3 are arranged opposite each other along a second direction, with its processing side facing the feeding component 3. The other processing component 2 and the feeding component 3 are arranged along a first direction, with its processing side offset towards the previous processing component 2, and the processing side of this processing component 2 can be arranged opposite to the clamping component 8.

[0046] Cutting component 4 is used to cut workpiece 7.

[0047] The clamping assembly 8 is used to clamp the workpiece 7. The clamping assembly 8 clamps the end of the workpiece 7 facing the processing side of the processing assembly 2, which improves the processing stability of the workpiece 7.

[0048] The advantages of the device in this embodiment are as follows: First, the feeding component 3 can both feed the workpiece 7 and move its position. Compared with traditional processing equipment, this reduces the number of times the workpiece 7 needs to be transferred and the number of intermediate transfer components required, thus significantly simplifying the equipment structure. Second, reducing the number of times the workpiece 7 needs to be transferred reduces the positional error of the workpiece 7. Third, the feeding component 3 fixes the workpiece 7, allowing one end of the workpiece 7 to be processed. The feeding component 3 then moves to the cutting component 4, where the pipe is cut. Simultaneously, the clamping component 8 clamps the cut workpiece 7 and moves it, allowing the other end of the workpiece 7 to be processed by the processing component 2. The overall processing flow is efficient and fast. Furthermore, this structure ensures that when the clamping component 8 clamps the workpiece 7, the clamping point is close to the end of the workpiece 7 being processed, improving processing stability and guaranteeing processing quality. Fourth, by controlling the feeding of the feeding component 3, the length of the processed part 7 can be adjusted when the cutting component 4 cuts the processed part 7. That is, in a batch processing flow, processed parts 7 of different lengths can be processed without adjusting the equipment. Fifth, the cost of expanding and modifying the equipment is very low. Specifically, the processing component 2 can include multiple processing parts. When adding or removing processing parts, only the travel of the feeding component 3 and the clamping component 8 needs to be adjusted (for example, the feeding component 3 is slidably connected to the frame 1 via a rail, and the length of the rail can be adjusted).

[0049] In some embodiments, the feeding assembly 3 includes a first base 31, an extension tube 35, a guide tube 36, and a conveying component. The first base 31 is movably connected to the frame 1 along a first direction, the extension tube 35 is connected to the first base 31, and the axial direction of the extension tube 35 extends along the first direction. The guide tube 36 is connected to the first base 31, and the axial direction of the guide tube 36 extends along the first direction. The extension tube 35 and the guide tube 36 are spaced apart along a second direction. The conveying component is disposed between the extension tube 35 and the guide tube 36.

[0050] The axes of extension tube 35 and guide tube 36 can be collinear. Extension tube 35 and guide tube 36 form a channel for conveying the processed part 7.

[0051] The extension tube 35 is used to input the workpiece 7, and the guide tube 36 is used to output the workpiece 7.

[0052] The conveying component is disposed between the extension tube 35 and the guide tube 36, so that the conveying component can apply force to the workpiece 7, thereby allowing the workpiece 7 to move along the extension tube 35 and the guide tube 36.

[0053] In some embodiments, a clamping cylinder 37 is provided at the output end of the guide tube 36.

[0054] The clamping cylinder 37 output from the guide tube 36 is used to clamp the workpiece 7 so that the workpiece 7 can be processed by the processing component 2 facing the feeding component 3.

[0055] The clamping cylinder 37 can be selected from the existing technology, and its structure and working principle are well known to those skilled in the art, and will not be described in detail here.

[0056] In some embodiments, the conveying component includes two movable plates 32, which are movably connected to the first base 31 in a direction perpendicular to the axial direction of the guide tube 36. The movable plates 32 are rotatably provided with a plurality of pulleys 33, which are spaced apart along the axial direction of the guide tube 36. A conveyor belt 34 is wrapped around the outer periphery of the plurality of pulleys 33.

[0057] For example, the movable plate 32 can move along a third direction, which can be perpendicular to the first direction and the second direction. When the first direction and the second direction are parallel to the horizontal plane 225, the third direction can be perpendicular to the first direction and the second direction and extend in the vertical direction.

[0058] The movable plate 32 is movable, so that the spacing between the conveyor belts 34 on the two movable plates 32 can be adjusted.

[0059] The conveyor belt 34 is used to contact the workpiece 7, and the conveyor belt 34 of the two movable plates 32 can cooperate to clamp the workpiece 7. When the conveyor belt 34 moves, the workpiece 7 can be pushed and moved.

[0060] The pulley 33 can be driven to rotate by a motor.

[0061] In some embodiments, the processing component 2 includes an outer chamfering component 21, an inner chamfering component 22, and a deburring component 23, and the outer chamfering component 21, the inner chamfering component 22, and the deburring component 23 of the two processing components 2 are arranged along a first direction.

[0062] The outer end chamfering component 21, the inner end chamfering component 22, and the deburring component 23 of the two processing components 2 are arranged in the same order. The advantage of this arrangement is that when the workpiece 7 moves in one direction, the processing of both ends of the workpiece 7 can be completed, which improves the processing efficiency of the workpiece 7.

[0063] In some embodiments, the outer end chamfering component 21 includes a second base 211, an adjusting seat 212, a rotating seat 213, and a grinding wheel 214. The second base 211 is movably connected to the frame 1 along a second direction. The adjusting seat 212 is rotatably connected to the second base 211, and the rotation axis of the adjusting seat 212 is parallel to the second direction. The adjusting seat 212 includes two opposing arms 215, each arm 215 having a first fixing hole 217 and a second fixing hole 216. The second fixing hole 216 is arc-shaped, and its center is located at the axis of the first fixing hole 217. The rotating seat 213 is disposed between the two arms 215 and has two mating holes 218, which are respectively opposite to the first fixing hole 217 and the second fixing hole 216. The grinding wheel 214 is rotatably connected to the rotating seat 213.

[0064] The second base 211 is movably connected to the frame 1 along the second direction, so that the position of the grinding wheel 214 relative to the end of the workpiece 7 can be adjusted.

[0065] The first fixing hole 217, the second fixing hole 216, and the mating hole 218 can be used for fasteners to pass through. For example, the mating hole 218 can be a threaded hole. When connecting the adjusting seat 212 and the rotating seat 213, a bolt can be passed through the first fixing hole 217 and threadedly connected to the mating hole 218 opposite to the first fixing hole 217. Similarly, another bolt can be passed through the second fixing hole 216 and threadedly connected to the mating hole 218 opposite to the second fixing hole 216. This allows the rotating seat 213 to be connected to the two arms 215 of the adjusting seat 212.

[0066] Of course, when selecting other types of fasteners in the prior art, the types of the first fixing hole 217, the second fixing hole 216 and the corresponding mating hole 218 can be adjusted.

[0067] The rotating base 213 may be equipped with a motor, or the rotating base 213 itself may be a motor, to drive the grinding wheel 214 to rotate.

[0068] When the fastener passes through the first fixing hole 217 and connects to the corresponding mating hole 218, the rotating seat 213 can rotate relative to the wall of the adjusting seat 212. When the fastener passes through the second fixing hole 216 and connects to the corresponding mating hole 218, the rotating seat 213 can be locked to the adjusting seat 212. This allows the installation angle of the rotating seat 213 to be adjusted, thereby allowing the rotation axis of the grinding wheel 214 and the rotation axis of the adjusting seat 212 to be in an intersecting state. This allows the grinding wheel 214 to chamfer the outer diameter of the end of the workpiece 7.

[0069] The axis angle of grinding wheel 214 can be referenced from the state shown in the attached figure.

[0070] During processing, the axis of the workpiece 7 can be parallel to the axis of rotation of the adjusting seat 212.

[0071] The advantages of the outer end chamfering component 21 in this embodiment are as follows: First, the hollow structure of the adjusting seat 212 reduces the risk of abrasive shavings accumulating on the rotating seat 213, thereby reducing the risk of damage to the rotating seat 213. Second, during chamfering, the adjusting seat 212 rotates while the grinding wheel 214 rotates, which completes the chamfering process, making it easier to control and reducing the risk of abrasive shavings adhering to the adjusting seat 212 and the rotating seat 213. Simultaneously, the workpiece 7 does not need to move during the chamfering process, improving the positioning accuracy of the workpiece 7. Third, because the axis of the grinding wheel 214 is inclined relative to the rotation axis of the adjusting seat 212, the abrasive shavings generated during the grinding wheel 214 have a speed that deviates from the workpiece 7 in the second direction. On the one hand, since the grinding wheel 214 processes the workpiece 7 multiple times, this reduces the risk of abrasive shavings accumulating on the surface of the workpiece 7, causing surface damage due to secondary cutting. On the other hand, to facilitate the collection of grinding debris, for example, the frame 1 can be provided with a dustproof chamber 9. Along the second direction, the dustproof chamber 9 includes two opposing side walls, each with a through hole, allowing the grinding wheel 214 and the workpiece 7 to extend into the dustproof chamber 9. Since the grinding wheel 214 has a speed deviating from the workpiece 7, the grinding debris can impact the two side walls of the dustproof chamber 9, facilitating the deceleration of the grinding debris and making it easier to collect. Third, the hollow structure of the adjusting seat 212 facilitates air circulation, which helps to cool the grinding wheel 214 and the motor that drives the grinding wheel 214. Fourth, the adjusting seat 212 and the rotating seat 213 can form overload protection. That is, the rotating seat 213 is fixed to the adjusting seat 212 by friction under the action of fasteners. When the grinding wheel 214 is subjected to excessive force exceeding the limit, the rotating seat 213 can rotate relative to the adjusting seat 212, forming overload protection.

[0072] In some embodiments, the inner chamfering component 22 and the deburring component 23 may each include a drive structure that moves along a second direction and a cutter 221 and a wire brush 231 wheel disposed on the drive structure. Of course, the two side walls of the dustproof chamber 9 are also provided with through holes for the cutter 221 and the wire brush 231 wheel to enter.

[0073] In some embodiments, the cutting tool 221 may have the following structure:

[0074] The cutting tool 221 may include a tool holder 222, which is connected to the drive structure. The tool holder 222 is provided with a cutting tool body, which may be triangular in shape. Along the thickness direction of the cutting tool body, the cutting tool body includes two opposing front cutting surfaces 223, connected by an inclined side cutting surface 224. The side cutting surface 224 and one front cutting surface 223 form a pointed structure, which forms the cutting edge. The side cutting surface 224 includes a plane 225, which connects to the tool holder 222 and the pointed structure. This plane 225 serves two purposes: firstly, it can be used for mounting and positioning the cutting tool 221; secondly, it can act as an impact buffer, absorbing impact energy when the cutting tool body encounters a sudden load, reducing the risk of chipping or breaking of the cutting edge.

[0075] In some embodiments, the cutting assembly 4 includes a drive unit 41, a cutting wheel 44, a base plate 42, and a pressing unit 43. The drive unit 41 is movably connected to the frame 1 along a third direction and includes a rotating end. The cutting wheel 44 is connected to the rotating end. The base plate 42 is connected to the frame 1 and is configured such that when the workpiece 7 moves to the cutting station, the workpiece 7 is placed on the base plate 42. The pressing unit 43 is disposed above the base plate 42 and is movably connected to the frame 1 along a third direction.

[0076] The drive unit 41 may include a motor for driving the cutting wheel 44 to rotate.

[0077] The third direction can be the direction shown by the Z-axis in the figure. As mentioned above, the third direction can be parallel to the vertical direction.

[0078] When the feeding assembly 3 carries the workpiece 7 to the cutting assembly 4, the feeding assembly 3 outputs the workpiece 7 along the second direction, and the end of the workpiece 7 can be supported by the base plate 42. After the workpiece 7 is output to the set length, the pressing part 43 moves down and presses the workpiece 7 onto the base plate 42, fixing the workpiece 7 to the base plate 42. At this time, the cutting wheel 44 can move down to cut the workpiece 7.

[0079] In some embodiments, the clamping assembly 8 includes a main body 81, two clamping arms, and two grippers 84. The main body 81 is movably connected to the frame 1 along a first direction. Each clamping arm includes two spaced-apart first connecting portions 82 and a second connecting portion 83 connecting the two first connecting portions 82. The main body 81 is disposed between the two first connecting portions 82, the first connecting portions 82 are rotatably connected to the main body 81, and the second connecting portions 83 are clearance-fitted to the main body 81. The two grippers 84 are respectively connected to the second connecting portions 83 of the two clamping arms.

[0080] The clamping arm has a U-shaped structure.

[0081] The second connecting part 83 and the main body 81 are fitted with a clearance, which increases the rotation range of the clamping arm. The advantage of this arrangement is that the two clamping arms can be fully separated to loosen the workpiece 7.

[0082] In some embodiments, the frame 1 is provided with a feeding ramp 5. Along the first direction, the feeding ramp 5 is provided on one side of the frame 1. The feeding ramp 5 is provided with a notch 51, which is used to accommodate the clamping assembly 8.

[0083] The inclined surface 5 is used to discharge the finished workpiece 7.

[0084] A baffle 6 is rotatably installed above the unloading ramp 5. The baffle 6 is used to prevent the workpiece 7 from sliding down or to release the workpiece 7 so that it slides down the unloading ramp 5 as needed.

[0085] The notch 51 can be located on the higher side of the unloading slope 5. The opening of the notch 51 is located on the highest side of the unloading slope 5. When the clamping assembly 8 moves the workpiece 7 into the notch 51, the clamping arm separates, and the workpiece 7 can fall on the unloading slope 5 and slide down the unloading slope 5.

[0086] In this embodiment, the second connecting part 83 of the clamping assembly 8 and the main body 81 are fitted with a clearance, which allows the clamping arm to be fully separated and rotated to the bottom of the inclined surface, reducing the risk of the clamping arm obstructing the downward movement of the workpiece 7.

[0087] On the other hand, this application provides a pipe cutting and chamfering method, applied to the pipe cutting and chamfering equipment in the above embodiments, including:

[0088] The workpiece 7 is conveyed along the second direction by the feeding assembly 3, so that the first end of the workpiece 7 can be located on the processing side of the processing assembly 2, which is opposite to the feeding assembly 3.

[0089] When conveying the workpiece 7, the output length should not be too long, just enough to ensure that the first end of the workpiece 7 can be processed by the feeding component 3.

[0090] The feeding assembly 3 moves along the first direction and the first end of the workpiece 7 is processed by the processing assembly 2.

[0091] The feeding assembly 3 continues to move along the first direction until it reaches the cutting assembly 4. The feeding assembly 3 then continues to convey the processed part 7 along the second direction until the discharge length of the processed part 7 reaches the set value.

[0092] The movable clamping assembly 8 clamps the workpiece 7, and the cutting assembly 4 cuts the workpiece 7.

[0093] The clamping assembly 8 continues to move along the first direction and processes the second end of the workpiece 7 by the processing assembly 2, which is spaced apart from the feeding assembly 3 along the first direction.

[0094] The workpiece 7 can be processed simultaneously at both ends by moving in one direction along the first direction, reducing the path that the workpiece 7 needs to take and simplifying the overall structure of the equipment. In addition, with this processing method, the feeding assembly 3 and the clamping assembly 8 do not need to be adjusted to ensure that their fixing points to the workpiece 7 are close to the end of the workpiece 7 being processed, which improves the fixing effect of the workpiece 7 and thus ensures the processing quality of the workpiece 7.

[0095] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
