Ultra-large coil pipe production system and production method thereof

Abstract

The invention relates to an ultra-large coil pipe production system which comprises a discharging device, a straightening device, a length measuring device, an ink-jet drying device, a forming device,a winding and discharging device, a roller hearth furnace and a transferring device. The transferring device comprises a carrying forklift and a transferring table, and the winding and discharging device winds a pipe on a stainless steel support; the pipe forms an ultra-large coil pipe on the stainless steel support; the roller hearth furnace is used for performing annealing treatment on the ultra-large coil pipe on the stainless steel support; the carrying forklift is used for carrying the annealed stainless steel support loaded with the ultra-large coil pipe to the transferring table, and the transferring table is used for separating the ultra-large coil pipe from the stainless steel support; and the carrying forklift is used for carrying the separated ultra-large coil pipe onto a woodsupport. The self-contained roller hearth furnace is adopted for annealing the pipe, the production cost of the pipe is reduced, the separation process of the pipe is completed through the transferring table with protrusions, and practicability is high.

Description

technical field [0001] The invention relates to a copper pipe processing technology, in particular to a production system and a production method for super large coil pipes. Background technique [0002] In the production process of precision seamless copper pipes, the online induction annealing super large plate production of the online annealing soft state super large plate unit is becoming more and more mature, and various copper pipe manufacturers have realized large quantities of supply. The traditional super large plate unit is as attached figure 1 As shown, the hard or semi-hard copper tube in the basket material 40 is passed through the straightening machine 12, the length measuring device 13, the online induction heating furnace 17, the heat preservation and cooling device 18, the tension device 19, the spraying tube by the discharging device 11. The ink drying device 14, the forming device 15 and then the production mode of the winding and unloading device 16, the ...

Problems solved by technology

[0003] Therefore, the traditional process adopts the online annealing and wooden support winding process for production. The production method is that the material frame coil is annealed and then the wooden support soft state winding finished product. Although the production process is short, each set of equipment needs online induction annealing. The investment cost is high and it is difficult to control the stability and consistency of the pipe performance. In addition, the energy consumption of induction online annealing is also higher than that of roller hearth furnace annealing of finished products (in production, the power consumption per ton of induction heating copper pipe is more than 200 degrees, and the roller The bottom furnace is below 120 degrees), and the production speed is limited due to the purge inside the pipe (in principle, the online annealing method does not exceed 200m / min), so this production method will increase the cost and efficiency of pipe production
