二、Main Technical Performance of Production Line

1. Overview: the production line is to produce diameter Ф 19— Ф 50mm, wall thickness 0.7-2.0mm, special equipment for high-frequency Longitudinal Welded Pipe and corresponding square pipe and special-shaped pipe. The equipment composition is from feeding to cutting and blanking, and the pipe making speed is adjusted accordingly with the change of pipe making specification.

2. Raw Materials: the applicable strip steel materials are hot-rolled or cold-rolled, pre galvanized strip steel coils such as ordinary carbon steel Q195 and Q235 (in accordance with GB700-88 or gb1591-88)

3. Production Capacity: Pipe Making Range

4. Strip Steel Specification (raw material): the applicable strip steel materials are hot-rolled or cold-rolled strip coils of ordinary carbon steel Q195 and Q235, pre galvanized strip steel, etc.

5. Square Pipe Production Mode: round to square, angle out

6. Unit Production Mode: continuous

7. Unit Operation Direction: left or right (determined by the process layout of the user's workshop)

8. Bottom Line of Pipe Making: + 760mm (can also be customized according to customer requirements)

9. Welding Mode: high frequency induction welding, 200KW.

10. Speed of Pipe Making: 30-120m / min

11. Total Power of Production Line: 430KW

三、Process Flow of Production Line: raw material (strip steel coil) → uncoiling → material storage → passive leveling → forming and rolling → high frequency welding → external burr removal → zinc supplement → spray cooling → sizing and shaping → rough straightening → fixed length cutting → pipe collection and binding.

四、Brief introduction to equipment configuration of each unit of the unit:

1. Double cone pneumatic uncoiler:

The function of uncoiler is to support and expand the coil, and the strip can enter the forming rolling smoothly The coil is opened pneumatically, and the feeding frame can be forward and reverse The opening speed of the coil can be adjusted, and the design of the brake device is to press the rubber skin with the cylinder, which is safe and stable.

2. Shear butt welding machine: it is used to cut the irregular parts of the head and tail of two rolls of strip steel and weld the two rolls of strip steel, so the machine can work continuously without shutdown and touch screen operation.

(1) width of strip : ≤ 160mm; Thickness of strip: 0.7-2.0mm

(2) Shear butt welding time : not more than 3 minutes

(3) Floor area (length) × (width) : 1200mm × 1200mm

(4) Feeding direction : according to user needs

(5) Production line elevation: 1200mm

(6) Pneumatic shearing, air pressure tightening;

(7) Welding speed range: 500-1000mm / min

3. Cage Silo:

The function of this part sleeve is to store a certain amount of steel strip for main machine rolling during steel strip feeding and head to tail welding, so as to ensure continuous production without shutdown.

Charging Motor: 5.5kw

Speed of Feeding : max200m / min

Storage Capacity: 400 ~ 600m

4. Molding Machine:

4.1 molding host

The function of this part is to press the passing strip steel into the required tube blank by using the forming die roll.

4.2 guiding, extruding and scarring mechanism:

The function of this part sleeve is to center the formed pipe blank weld and send it to the extrusion mechanism to close the pipe seam for welding, and then remove the external welding scar with a planer, so as to obtain a flat and smooth welding surface.

4.3 cooling water tank: the water tank spray type is adopted to fully cool the welded pipe blank. Widening type

4.4 sizing host:

The function of this part set is to finish the tube blank after forming and cooling, so as to meet the geometric dimensions required by the drawing or users.

4.5 straightening device: function: conduct on-line rough straightening to achieve ideal flatness.

5. Computer flying saw: (cold saw) this product is used to cut the formed steel pipe without hairy thorn to a fixed length

6. Blanking raceway, pneumatic unilateral material pulling and unloading rack: the function is to transport the finished steel pipe cut by fixed length sawing.

7. High frequency Induction Heating Welding Machine: the high frequency of the unit is 200 KW
