STT50F Automatic Electric 1300W Metal Rolling Pipe Threading Machine
Introduction
This machine is applicable to cutting, threading and inner hole chamfering (the chamferer is optional) of pipes for water, electricity and gas, and has the copying device able to automatically cut the standard taper pipe thread, with a reliable clamping device and an advanced cooling & lubrication system. Therefore, adopting this machine can lengthen the service life of the threading die, and avoid the deformation & slipping of the pipe clamp, so as to obtain the high-quality taper pipe thread. This machine is widely used in equipment installation, building and other industries, regarded as the ideal equipment to improve work efficiency, accelerate project progress, guarantee project quality and reduce labor intensity. (It is an ordinary round-steel threading machine, only applicable to the ordinary round-steel threading. The operating mode and machine structure are basically the same.)
Features
1. 1300W copper sensing motor, small noise, long use life,
fulfillment of full-dimension thread at one time.
2. Exclusive hard tooth-surface high-speed gearbox, with small
noise, long use life and high efficiency.
3. Jagged hammer panel design, firm clamp pipe, convenient
operation.
4. Standard collocation of 50A multi-functional die head, die is
replaced to process the round steel and wire pipe thread.
5. Double guide post cutting knife is accurate and durable.
6. Enhance type guide post trunnion can upgrade the stable
properties of machine.
7. Large modulus oblique gear main shaft gear, super-large torque
for easy transmission.
8. Selection of high efficiency, quality and performance-price
ratio.

How to Threading
(1) Pull the cutting knife frame and chamferer; put down die head to touch the copying block. After reliable positioning of die head, press the button to start the machine.
(2) Rotate the pipe in anti-clockwise direction, rotate the hand wheel of cutting feed, and make die head get close to the pipe.
(3) Apply force to the hand wheel of cutting feed, until die head makes 3 ~4 threads on the pipe.
(4) Then, loosen the hand wheel of cutting feed, so the machine starts automatic threading. When roller of die head goes over copying block and falls down, threading die will open automatically and the threading is completed (Z13 T–M18 threading machine is required to turn back to make the threading die exit). Z1T–50A threading die shall be loosened manually.
(5) Machine halt. Return to the carriage, until the whole die head exits pipe end. Pull out die head, lock the handle and pull up the die head.
Important Notice
1. This machine shall be used with reliable grounding and anti-creep device.
2. Children are prohibited from touching this machine to avoid injury.
3. This machine shall not use the same socket with large-power machines, such as electric welding machine.
4. Pipe clamps shall not be installed on the machine, to avoid cracking of main components such as the cabinet.
5. Saponified solution shall not be used for cooling, such as water.
6. When above 2½″ pipe thread is made, it is required to adopt the low-gear processing mode,
7. When leaving factory, centrality of the machine has been measured, but pipes on the market have certain ovality at present. After machining, screw threads may be deep on one side and shallow on the other side. If they affect use, please check the quality of pipes.
Common Faults and Solutions
Common faults | Reasons | Solutions |
---|---|---|
1. Motor doesn’t work or work with intermittent sound | 1. Fuse is burnt down 2. The plug is not well connected 3. The internal part of the cable is broken 4. The button switch is not well connected 5. 100UF Capacitor breakdown 6. Environment temperature is too low, and lubricating grease solidifies. | 1. Detect the broken part with a multimeter and use a new fuse 2. Replace the plug or socket 3. Replace the power cord 4. Replace the switch 5. Use a new capacitor 6. Operate indoor or help it to start up |
2. Pipe fails to be fixed and slips during threading | 1. Insufficient hammering force 2. Clamping jaw tip turns over 3. One clamping jaw tip breaks or has a gap | 1. Hammer hard 2. Adjust clamping jaw tip 3. Use a new clamping jaw tip |
3. Cutting knife fails to cut, and fails to produce proper threads | 1. Sharp corner of cutting knife is worn out and becomes an arc 2. Pin roll of cutting knife is worn out 3. Cutting force is insufficient | 1. Replace cutting knife blade 2. Replace pin roll 3. Cut more vigorously |
4. Knife cannot cut during threading | 1. Opening of threading die is too small at the start of threading 2. Several teeth of knife head are broken 3. Knife head doesn’t match 4. There is scrap iron in die groove | 1. Use threading die correctly 2. Replace knife 3. Re-install knife head 4. Clean threading die head |
5. Front chuck loosens and falls down | Screws loosen due to long-term use | Inspect them timely |
