[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation modes.

[0022] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, an intelligent diameter-expanding machine for stainless steel pipes;

[0023] It includes a support platform 1, a diameter-expanding component 3 and a moving shell 18. Two groups of electric slide rails 8 are arranged on the top of the support platform 1. The output end of the electric slide rail 8 is provided with a slider 9. One side of the slider 9 is connected with a connecting frame 10. A first electric push rod 11 is arranged inside the connecting frame 10. The output end of the first electric push rod 11 is provided with a second electric push rod 12. The output end of the second electric push rod 12 is provided with a support rod 13. A threaded rod 17 is threadedly penetrated through the inside of the moving shell 18. The bottom end of the threaded rod 17 is provided with a drive motor 16. A flow guide block 14 is arranged on the top of the support platform 1, and the flow guide block 14 is in a right-angled triangle shape. The flow guide block 14 is located between the two groups of electric slide rails 8. The flow guide block 14 is located in front of the moving shell 18. Two groups of mounting plates 15 are arranged on the back of the support platform 1. The drive motor 16 is arranged at the bottom end of the mounting plate 15.

[0024] The slider 9 is the output end of the electric slide rail 8. The connecting frame 10 is used to connect between two groups of sliders 9. After using the controller 2 to control the simultaneous operation of the two groups of electric slide rails 8, the two groups of sliders 9 can adjust their usage positions on the electric slide rails 8. After the slider 9 slides to both sides of the lower positioning block 7, the operation of the first electric push rod 11 can push the second electric push rod 12 to adjust the usage height. When the second electric push rod 12 operates, the support rod 13 can extend a certain length, and the support rod 13 can be inserted into the lower positioning block 7 to support the inside of the steel pipe after diameter expansion. By the coordinated operation of the electric slide rail 8, the first electric push rod 11 and the second electric push rod 12, the steel pipe after diameter expansion can be placed on the top of the diversion block 14. The diversion block 14 is used to divert and move the steel pipe after diameter expansion, so that the steel pipe rolls into the moving shell 18 on the back of the support table 1 for storage. By operating the drive motor 16 to rotate the threaded rod 17 to drive the moving shell 18 to move downward, the usage height of the moving shell 18 is reduced, which is convenient for discharging the steel pipe after diameter expansion processing;

[0025] Similarly, after discharging, place the steel pipe to be processed by diameter expansion into the moving shell 18. By operating the drive motor 16, rotate the threaded rod 17 to drive the moving shell 18 to rise to the lower part of the electric slide rail 8. By the coordinated operation of the electric slide rail 8, the first electric push rod 11 and the second electric push rod 12, the steel pipe to be processed by diameter expansion can be placed into the lower positioning block 7, thus completing the auxiliary feeding of the steel pipe.

[0026] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, intelligent diameter expansion machine for stainless steel pipes;

[0027] One side of the support table 1 is provided with a controller 2. Two groups of diameter expansion assemblies 3 are symmetrically arranged on the top of the support table 1. The top of the support table 1 is provided with a support frame 4. The top of the support frame 4 is provided with a cylinder 5. The output end of the cylinder 5 is detachably provided with an upper positioning block 6. The top of the support table 1 is provided with a lower positioning block 7, and the lower positioning block 7 is located below the upper positioning block 6.

[0028] The support platform 1 is the main support component of the intelligent pipe diameter expanding machine for stainless steel pipes. After the controller 2 is electrically connected to the internal electrical components of the intelligent pipe diameter expanding machine for stainless steel pipes, the controller 2 can be used to regulate the operation of the internal electrical components of the intelligent pipe diameter expanding machine for stainless steel pipes. The pipe diameter expanding component 3 is an existing technology and is composed of two expanding columns with different diameters. The pipe diameter expanding component 3 can move back and forth, left and right on the top of the support platform 1, so that the expanding columns with different diameters are inserted into the inside of the steel pipe placed inside the lower positioning block 7. The support frame 4 provides a suitable support height for the air cylinder 5. When the air cylinder 5 operates, the use position of the upper positioning block 6 can be adjusted. By using the combined support of the upper positioning block 6 and the lower positioning block 7, the steel pipe that needs to be subjected to pipe diameter expansion treatment can be squeezed and positioned, facilitating the pipe diameter expanding component 3 to perform pipe diameter expansion treatment on the steel pipe. The upper positioning block 6 is detachably arranged at the bottom end of the output end of the air cylinder 5 by means of threads, and the lower positioning block 7 is assembled and detachably arranged at the top end of the support platform 1, facilitating the subsequent disassembly and assembly of the upper positioning block 6 and the lower positioning block 7.

[0029] During use, place the steel pipe that needs to be subjected to pipe diameter expansion treatment inside the moving shell 18. By operating the driving motor 16, the threaded rod 17 rotates to drive the moving shell 18 to rise to the lower part of the electric slide rail 8. By using the coordinated operation of the electric slide rail 8, the first electric push rod 11 and the second electric push rod 12, the steel pipe that needs to be subjected to pipe diameter expansion treatment can be placed inside the lower positioning block 7, thus completing the auxiliary feeding of the steel pipe.

[0030] When the air cylinder 5 operates, the use position of the upper positioning block 6 can be adjusted. By using the combined support of the upper positioning block 6 and the lower positioning block 7, the steel pipe that needs to be subjected to pipe diameter expansion treatment can be squeezed and positioned, facilitating the pipe diameter expanding component 3 to perform pipe diameter expansion treatment on the steel pipe.

[0031] After the steel pipe is subjected to pipe diameter expansion, the electric slide rail 8 drives the slider 9 to slide to both sides of the lower positioning block 7. The first electric push rod 11 operates to adjust the use height of the second electric push rod 12. The second electric push rod 12 operates to insert the support rod 13 into the inside of the lower positioning block 7 to support the inside of the steel pipe after pipe diameter expansion. By using the coordinated operation of the electric slide rail 8, the first electric push rod 11 and the second electric push rod 12, the steel pipe after pipe diameter expansion can be placed on the top of the diversion block 14. By using the diversion block 14 to divert and move the steel pipe after pipe diameter expansion, the steel pipe rolls into the moving shell 18 on the back of the support platform 1 for storage. By operating the driving motor 16 to rotate the threaded rod 17 to drive the moving shell 18 to move downward, the use height of the moving shell 18 is reduced, facilitating the feeding of the steel pipe after pipe diameter expansion treatment.
