[0003] In traditional processing methods, the blank pipe fittings need to be cut into fixed length segments first, and then the pipe fittings are sent to an extrusion extrusion machine for extrusion processing to form an extrusion structure 13 on the pipe fittings.

[0022] A processing method for a capillary extrusion drum punching and cutting equipment includes the following specific steps:

[0023] S1: The pipe fittings are straightened by the straightening components;

[0024] S2: The pipe moves towards the extrusion drum flattening and shearing component under the drive of the feeding component. The feeding component conveys the pipe a fixed length each time. The pipe is driven by the feeding component to move and reach the processing position. After reaching the processing position, the pipe passes through the extrusion drum flattening and shearing component and passes between the first and second pull rollers on the pulling component. At this time, the section of the pipe located in the extrusion drum flattening and shearing component is the processing section.

[0025] S3: Extrusion, flattening, and shearing process: The clamping cylinder drives the upper die component to move downwards. The first lower die and the first upper die, the second lower die and the second upper die, the third lower die and the third upper die, and the fourth lower die and the fourth upper die clamp the processing section. The upper flattening die and the lower flattening die punch the pipe fitting, forming a flattened section in the middle of the pipe fitting. Under the action of the punch and the groove, the bending structure is symmetrically processed on both sides of the flattened section. At the same time, the shearing die cuts the processing section from the middle, forming the pre-processed section and the post-processed section.

[0026] Then, the extrusion cylinder pushes the first lower die and the first upper die to move towards the fourth lower die and the fourth upper die, respectively, so that the first lower die is closer to the second lower die, the first upper die is closer to the second upper die, the third lower die is closer to the fourth lower die, and the third upper die is closer to the fourth upper die. Through the movement between the first lower die and the second lower die, the movement between the first upper die and the second upper die, the movement between the third lower die and the fourth lower die, and the movement between the third upper die and the fourth upper die, the extrusion drum structure is symmetrically processed on both sides of the processing section.

[0027] After the extrusion drum mechanism completes its processing, the extrusion drum cylinder resets, and then the clamping cylinder drives the upper mold component to move upward and reset; the cut-off pipe is the processed pipe product.

[0028] The pipe fitting is pulled out from the extrusion drum flattening and shearing component by the rotation of the first pulling roller, thus realizing the unloading; the pre-processing section serves as the second half of the pipe fitting, and the post-processing section serves as the first half of the next pipe fitting to be processed;

[0029] S4: Repeat step S3.

Through the extrusion, flattening, and shearing components, it can simultaneously perform extrusion, stamping, and shearing processes on the pipe, thereby creating the required flattened and bent structures at both ends of the pipe and fabricating an extrusion mechanism on the pipe, completing multiple capillary processing steps in one operation. This invention has a high degree of automation; the entire process requires no manual intervention, reducing labor costs and significantly improving processing efficiency.

[0063] The processing method of the capillary extrusion drum punching and cutting equipment includes the following specific steps:

[0064] S1: The pipe fittings are straightened by the straightening components;

[0065] S2: The pipe moves towards the extrusion drum flattening and shearing component under the drive of the feeding component. The feeding component conveys the pipe a fixed length each time. The pipe is driven by the feeding component to move and reach the processing position. After reaching the processing position, the pipe passes through the extrusion drum flattening and shearing component and passes between the first and second pull rollers on the pulling component. At this time, the section of the pipe located in the extrusion drum flattening and shearing component is the processing section.

[0066] S3: Extrusion, flattening, and shearing process: The clamping cylinder drives the upper die component to move downwards. The first lower die and the first upper die, the second lower die and the second upper die, the third lower die and the third upper die, and the fourth lower die and the fourth upper die clamp the processing section. The upper flattening die and the lower flattening die punch the pipe fitting, forming a flattened section in the middle of the pipe fitting. Under the action of the punch and the groove, the bending structure is symmetrically processed on both sides of the flattened section. At the same time, the shearing die cuts the processing section from the middle, forming the pre-processed section and the post-processed section.

[0067] Then, the extrusion cylinder pushes the first lower die and the first upper die to move towards the fourth lower die and the fourth upper die, respectively, so that the first lower die is closer to the second lower die, the first upper die is closer to the second upper die, the third lower die is closer to the fourth lower die, and the third upper die is closer to the fourth upper die. Through the movement between the first lower die and the second lower die, the movement between the first upper die and the second upper die, the movement between the third lower die and the fourth lower die, and the movement between the third upper die and the fourth upper die, the extrusion drum structure is symmetrically processed on both sides of the processing section.

[0068] After the extrusion drum mechanism completes its processing, the extrusion drum cylinder resets, and then the clamping cylinder drives the upper mold component to move upward and reset; the cut-off pipe is the processed pipe product.

[0069] The pipe fitting is pulled out from the extrusion drum flattening and shearing component by the rotation of the first pulling roller, thus realizing the unloading; the pre-processing section serves as the second half of the pipe fitting, and the post-processing section serves as the first half of the next pipe fitting to be processed;

[0070] S4: Repeat step S3.

[0071] This invention integrates functions such as pipe straightening, automatic feeding, stamping, extrusion, and automatic cutting. Through the extrusion, flattening, and shearing components, it simultaneously performs extrusion, stamping, and shearing on the pipe, thereby creating the required flattened and bent structures at both ends of the pipe and fabricating the extrusion mechanism on the pipe, completing multiple capillary processing steps in one operation. This invention boasts a high degree of automation, requiring no manual intervention throughout the entire process, reducing labor costs and significantly improving processing efficiency.

[0072] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.

7. A processing method based on the capillary extrusion drum punching and cutting processing equipment according to claim 6, characterized in that, The specific steps include the following: S1: The pipe fittings are straightened by the straightening components; S2: The pipe moves towards the extrusion drum flattening and shearing component under the drive of the feeding component. The feeding component conveys the pipe a fixed length each time. The pipe is driven by the feeding component to move and reach the processing position. After reaching the processing position, the pipe passes through the extrusion drum flattening and shearing component and passes between the first and second pull rollers on the pulling component. At this time, the section of the pipe located in the extrusion drum flattening and shearing component is the processing section. S3: Extrusion, flattening, and shearing process: The clamping cylinder drives the upper die component to move downwards. The first lower die and the first upper die, the second lower die and the second upper die, the third lower die and the third upper die, and the fourth lower die and the fourth upper die clamp the processing section. The upper flattening die and the lower flattening die punch the pipe fitting, forming a flattened section in the middle of the pipe fitting. Under the action of the punch and the groove, a curved structure is symmetrically processed on both sides of the flattened section. At the same time, the shearing die cuts the processing section in the middle, forming the pre-processed section and the post-processed section. Then, the extrusion cylinder pushes the first lower die and the first upper die to move towards the fourth lower die and the fourth upper die, respectively, so that the first lower die is closer to the second lower die, the first upper die is closer to the second upper die, the third lower die is closer to the fourth lower die, and the third upper die is closer to the fourth upper die. Through the movement between the first lower die and the second lower die, the movement between the first upper die and the second upper die, the movement between the third lower die and the fourth lower die, and the movement between the third upper die and the fourth upper die, the extrusion drum structure is symmetrically processed on both sides of the processing section. After the extrusion drum mechanism completes its processing, the extrusion drum cylinder resets, and then the clamping cylinder drives the upper mold component to move upward and reset; the cut-off pipe is the processed pipe product. The pipe fitting is pulled out from the extrusion drum flattening and shearing component by the rotation of the first pulling roller, thus realizing the unloading; the pre-processing section serves as the second half of the pipe fitting, and the post-processing section serves as the first half of the next pipe fitting to be processed; S4: Repeat step S3.
