Problems solved by technology

[0002] At present, some of the original domestic galvanized pipes are produced by electroplating, and some are welded by galvanized sheets. The galvanized pipes are galvanized by electro-galvanizing. The thickness of the coating is difficult to control, the coating is thin, the production speed is slow, and the cost is high. Most of the hot-dip galvanizing adopts the cage dip galvanizing method. The steel pipe is cut into the required length, placed in the cage and immersed in a zinc pot. In this way, the zinc layer is coated on both sides, but the actual application is only The outer surface of the steel pipe needs to be galvanized, and the waste of double-sided galvanizing is serious; in addition, the welding process of the galvanized sheet is to roll-form the hot-dip galvanized sheet and weld it. Seam repair galvanized layer
Galvanized on steel pipes, the production efficiency of these methods is low, continuous production is not possible, the process is complicated, the production cost is high, and the labor intensity is high.

Embodiment Construction

[0011] Entrance section: first place the steel coil on the uncoiler 1 with the steel coil car, cut off the plate head with the head and tail cutter 2, flatten through the first pinch roller 3 and pass through the steel plate welding machine 4, and the previous steel coil Cut the head and tail of the coil 2 to cut off the irregular tails of the steel plates and weld them together, change the position and direction of the steel strip through the pinch roller 5, so that the steel strip enters the disc looper 6 from the horizontal direction to the vertical direction , the steel strip enters the disc looper 6, when the coil is normally uncoiled, the disc looper 6 stores the material, and when the coil is changed and welded, the disc looper 6 discharges the material, which meets the requirements of continuous production of the unit;

[0012] Process section: The steel strip comes out of the disc looper 6 and is turned by the second pinch roller 7, so that the steel strip changes from...

Abstract

The invention provides a device for continuously hot dip galvanizing a pipe. A continuous production line device is adopted to solve the problem that a steel pipe cannot be continuously galvanized in the prior art. The device for continuously hot dip galvanizing the pipe comprises an uncoiling machine 1, cropping tail scissors 2, a first withdrawal roll 3, a steel plate welder 4, a withdrawal roll 5, a disc-type loop 6, a second withdrawal roll 7, a straightening device 8, a rolling molding machine 9, a straight welding machine 10, a pre-heating cleaner 11, a zinc groove 12, an annular air knife 13, a cold air blower 14, a steel pipe clamping and delivering device 15, fixed-length rear scissors 16 and a stacking apparatus. The stacking apparatus is provided with two stackers, one of which is put into operation while the other is for later use. The device for continuously hot dip galvanizing the pipe improves the production efficiency and saves cost.
