Description

Technical Field

[0001] The invention relates to the technical field of cooling pipe processing, and in particular to a coil device for processing cooling pipes. Background Art

[0002] In equipment that requires heat exchange, such as boilers and reactors, spiral cooling pipes are one of the indispensable components. The spiral cooling pipes need to be processed using coil equipment. Existing coil equipment mainly uses a conveying wheel to convey the cooling pipes, and a bending wheel to squeeze the cooling pipes into coils. When coiling, the bent cooling pipes are lifted by a liftable lifting plate, so that the cooling pipes are bent into a three-dimensional spiral shape.

[0003] However, when the existing coil equipment is working, the bent cooling pipe directly contacts the lifting plate and generates friction. After the cooling pipe is produced, its outer surface will be worn, affecting the product quality. After the cooling pipe coil is processed, the surface of the cooling pipe needs to be polished. The grinding operation of the spiral cooling pipe is inconvenient and the processing efficiency is low. In addition, due to the large gravity of the metal cooling pipe itself, after the coil reaches a certain height, the cooling pipe will change its pitch due to its own gravity. After the production is completed, the pitch size of the cooling pipe needs to be corrected, and the process is relatively cumbersome. Therefore, a coil device for processing cooling pipes is needed to solve the above problems. Summary of the invention

[0041] The working process of the present invention is as follows:

[0042] When the cooling pipe 8 needs to be coiled, first adjust the distance between the adjustable conveying wheel 22 and the fixed conveying wheel 25 according to the diameter of the cooling pipe 8, place the cooling pipe 8 between the adjustable conveying wheel 22 and the fixed conveying wheel 25, and rotate the fixed conveying wheel 25 to convey the cooling pipe 8.

[0043] When the front end of the cooling tube 8 reaches the position of the bending assembly 3, the hydraulic cylinder 33 drives the second slider 31 to slide, so that the second slider 31 drives the bending wheel 32 to squeeze the cooling tube 8, so that the cooling tube 8 is bent. The position of the bending wheel 32 is adjusted and maintained according to the set spiral diameter, and the conveying assembly 2 conveys the cooling tube 8 to realize continuous coil processing.

[0044] Guide the front end of the cooling pipe 8 into the driving ring 52 and into between the two grinding blocks 55. Since a spring is arranged in the sleeve 53, the grinding block 55 is pressed against the outer wall of the cooling pipe 8. Start the grinding motor 511. The grinding motor 511 drives the driving shaft 59 to rotate. The driving shaft 59 drives the two gears 58 to rotate through the first belt 510, so that the ring gear 56 drives the driving ring 52 to rotate continuously. The driving ring 52 drives the grinding block 55 to rotate to grind the surface of the cooling pipe 8. At the same time, it prevents the cooling pipe 8 from sliding in contact with the surface of the lifting plate 42 to cause wear.

[0045] Place the front end of the cooling pipe 8 on the fixing plate 72, engage the clamp 73 on the cooling pipe 8, and turn the clamping bolt 74 to clamp and fix the cooling pipe 8; the fixed conveying wheel 25 rotates to drive the lifting and adjusting screw 62 to rotate through the second transmission belt 63, and the lifting and adjusting screw 62 drives the lifting column 61 to move upward, thereby achieving traction on the upper end of the cooling pipe 8 to avoid large deformation of the cooling pipe 8 due to its own gravity.
