Factory Price Metal Steel Frame Full Auto/Automatic Changed Type C and Z Purlin Profile Cold Roll Forming Machine Construction Material

Components description of C Purlin roll forming machine  

1. Guide device 
Feeding material guide device, use high speed steel on both sides; its feature of
High hardness, high wear resistance and high heat resistance to guarantee long life of machine.

2. Rollers of cz purlin roll forming machine

All Rollers are made from Cr12MOV.,Hardness 58-60HRC.
CNC machines can improve rollers precision.
Chromate finish on surface to add hardness of rollers.

3. High Accuracy Shafts

Solid shafts dia. 82 or 90mm for different material thickness.
All shafts are tooled twice by cylindrical grinding machine to ensure final precision.
Guarantee buyers get high accuracy deck sheet from Zhongyuan made machine.

4.Design bearings inside forming rollers

Design bearings inside the rollers to allow machine run with less loading so that rollers not easy to damage.
Ensure the same speed between all the rollers, no speed difference between rollers, improve the forming accuracy.
Bearings are helping to prolong machine life. Our made forming machines are allowed using more 15 years.

5. Main new type c purlin roll forming machine body

CZ purlin roll forming machine frame made from H450 type steel by welding,planned on surface to guarantee precision
Side wall thickness: 45mm

Motor Driving, Worm gear driving transmission, about 15-steps stations to form
Main Motor=7.5KWx3, Frequency speed control
All the screw bolts with grade 8.8(Some other factories use low grade4.8) to ensure fix the machine structure tightly and long life during the machine long time running.
Forming speed 18m/min.

All processed rollers are assembled on the carpet to avoid scratching on the rollers’ surface.

6. Automatic Cutting system
Automatic pre-cutting style, no need change cutter for different purlin sizes.
All cutting frame are heat treatment to remove the original stress of steel, reduce deformation, improve stability
Cutting tool material: Cr12MoV,hardness can reach 58-60Hrc.
Machine can cut as buyers wanted sheet length,full automatically.
7. Automatic PLC Control System
Control The Quantity And Cutting Length Automatically
Input the production data(such as production quantity,Length,etc.)on the touch screen , machine can finish the set production plan automatically.
One time buyer can set 20 batch data in the programme.

Components of control system	PLC, Inverter, Touch Screen, Encoder, relays, etc
PLC	Mitsubishi (Japanese brand) (Siemens for option)
Inverter	Mitsubishi (Japanese brand) (Siemens for option)
Touch screen	Mitsubishi (Japanese brand) (Siemens for option)
Encoder	OMRON or NEMICON (Japan brand)
Limit switch	Cut-to-Length Tolerance≤±1 mm

Advantages of this CZ purlin machine
This CZ roll forming machine is one automatic purlin rolll former. When user wants to make different sizes of Cee or Zee or U shape purlin , people key in and then the control system adjusts the different sizes automatically. Just push the button and the rollers will automatically adjust the required sizes without being adjusted by people.
Change of C type or Z type, change the turnover device manually. Within 20 minutes finish change from C to Z purlin.
