Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of MPP pipe forming and blanking tools, and in particular to MPP pipe forming and blanking mechanisms. Background Technology
[0002] In the process of MPP pipe forming and processing, the blanking stage is a key step to ensure product quality and production efficiency. Traditional MPP pipe blanking methods often rely on manual assistance or simple mechanical structures, which have many shortcomings in the process of pipe transportation and cutting. Specifically, existing feeding mechanisms for MPP pipes lack stable and effective clamping and guiding structures, making the pipes prone to shifting during transport. This shift not only leads to deviations in the subsequent cutting position, affecting the dimensional accuracy of the product, but also increases safety hazards during processing due to pipe swaying. Furthermore, the instability of the pipes during the cutting stage further exacerbates fluctuations in cutting quality, making it difficult to meet the requirements of high-precision processing. Among these issues, the problem of pipe shifting during transport is particularly prominent, severely restricting the overall efficiency of MPP pipe forming and feeding and the product qualification rate. Therefore, these problems need to be addressed. Utility Model Content

[0016] Working principle: When using this invention, power is supplied to the device, and the servo motor 7, the first transmission motor 11, and the second transmission motor 23 are started. The rotation speed of the servo motor 7 will be similar to that of the first transmission motor 11. The servo motor 7 drives the limit wheel 8 to rotate. The first transmission motor 11 drives the first transmission belt 13 mounted on the first drive platform 12 to rotate. The first transmission belt 13 drives the first transmission roller 9 and the second transmission roller 10 mounted on the transmission platform 2 to rotate, thereby driving the first transmission belt 26 to rotate. The second transmission motor 23 drives the belt mounted on the second drive platform 27 to rotate. The second transmission belt 28 rotates, which drives the third transmission roller 24 and the fourth transmission roller 25 to rotate, thereby driving the second transmission belt 29 to rotate. The pipe is placed on the top surface of the first transmission belt 26. The limit electric push cylinders 5 installed on both sides of the inner cavity of the contact platform 1 are activated. The limit electric push cylinders 5 drive the limit block 6 to move, so that the limit wheel 8 is in contact with the limit pipe. At the same time, the lifting cylinder 16 installed on the top surface of the first limit platform 14 and the cutting motor 17 installed at the output end of the lifting cylinder 16 through a right-angle tube are activated. The cutting motor 17 drives the cutting disc 18 to rotate. The pipes transported by the first transmission belt 26 are cut. Before the pipes enter the cutting process (i.e., when the pipes are located in the inverted trapezoidal groove opened in the feeding box 3), the servo motor 7, the first transmission motor 11, and the second transmission motor 23 will stop working. The first abutting cylinder 19 installed on the top surface of the first limiting platform 14 will start to abut the first abutting block 20 against the outside of the pipe. At the same time, the second abutting cylinder 21 installed on the top surface of the second limiting platform 15 will start to abut the second abutting block 22 against the outside of the pipe. (The installation position of the second limiting platform 15 can be opened on the top surface of the feeding box 3 according to the requirements of different batches of pipes.) After the pipe fitting is fixed in the sliding groove, the cutting motor 17 is started. The cutting motor 17 drives the cutting disc 18 to rotate. The lifting cylinder 16 drives the cutting motor 17 and the cutting disc 18 to move down to cut the pipe fitting. After the cutting is completed, the lifting cylinder 16 drives the cutting motor 17 and the cutting disc 18 to reset. The first abutting cylinder 19 and the second abutting cylinder 21 are reset. The servo motor 7, the first transmission motor 11 and the second transmission motor 23 are started, which drive the cut pipe fitting to the slot of the collection platform 4 to slide down for collection. That is, the above steps complete the cutting cycle of one pipe fitting.
