Single wall corrugated pipe forming machine equipment installation and debugging and technical process

Single wall corrugated pipe forming machine equipment installation and debugging process

1. The equipment in accordance with the schematic installed, more levels, a seed screw (if required).

2. Connect the water electricity gas, pay attention to the difference between inlet and outlet pipe.

3. Change the gear oil. The inside of the gear box oil should be replaced before boot, oil added to the glass window, special gear oil, local good buy. Every 3 ~ 6 months after replacement.

4. Extruder single electric test.

5. After extrusion machine electricity heating to set temperature, extrusion test

6. Forming machine electricity empty machine test

7. Winding machine electricity No-load test

More than 8. Separate test is completed, the extrusion machine, sealing gas rod installation, extrusion test.

Note: do not heat up before completion, must pay attention to the use of different materials of different process temperature, do not heat in extruder without material or not to set temperature under the condition of extruder operation!

Single wall corrugated pipe forming machine process

A heating.

(1) extruder and head body heat, according to the set temperature of the heating, in 1.5 2

Hour or so.

(2) the mouth mould parts, with uniform burner barbecue to working temperature, attention must be uniform, otherwise

Can cause deformation of the mould, core mould.

(3) module of heating, with uniform burner barbecue to 40 ℃ or so.

2. The adjustment of the die

After heating normal can boot, boot speed first, see if mouth mould of billet material evenly around, such as uneven adjustable screw until evenly. At the same time, have a look at the material temperature is in line with the extrusion temperature, after a period of time will machine stop.

3. The wire imported

Reliable billet uniformity and normal after extrusion temperature, stopped the machine and the wire from the wire import import, export mode about 30 mm.

4. Check the gas path

Open the manual valve to see if air permeability, check the gas pressure at the same time.

5. Adjust the machine before and after the position, push the machine to finish mold exports, there are two of the intermediate position of the corrugated piece of closed completely, bolted to death, check if there is a knock against phenomenon around the nose.

6. Boot

Gas mouth through gas pole screw twist on the mandrel, gas screw rod, screw, from behind the machine must be two people, a person holding a gas in front of the mouth to in the center of the core rod, the one will stem from behind the machine through the gas, screw on the core rod, the machine quickly and then be moved to the specified location, open the host at the same time, the release valve, pay attention to this a few movement must be coherent, remember to pay attention to safety at the same time, and then in the wire rod from gas don't wear out on the material base, have a look at the products shape, if corrugated too full and flash, proved that air pressure is too great, will air a little. On the other hand, if you don't molding corrugated, proved that air pressure is too small, will be up the pressure. If the corrugated tube wall thickness is too thick, can machine drive a bit faster, or extruder to drive slowly, on the other hand, if the corrugated pipe is too thin, can machine will slow down a little, or drive faster extrusion machine, the after being normal to synchronous speed slowly.

Seven coiling. After waiting for the pipe out of the normal, but in the take-up reel, pay attention to the winding knob and adjust the reel, don't roll is too tight, don't pull corrugated width deformation.
