Raw material ：
l Specifications: Φ15~Φ40mm,mainly 15-25mm, Length:2.5-7.3m
l Material composition: All kind of Alloy Steel, Stainless Steel, Spring Steel, Bearing Steel，heat treated steel, free cutting steel, valve steel, hardened & tempered steel.
l Speed & productivity chart as follows:
|Input voltage||three phase 380v 50-60HZ|
The main processing machine is pre-stress structure with four-pillars. There is a straightening roller on upper and lower machine boy separately. The upper roller is concave, the lower roller is convex. According to the diameter and characteristics of raw material, we need to adjust the two rollers angle separately. For electrical lift part, we need to adjust the gap between two rollers. Start the cooling and lubrication system, the straightening and polishing of raw material is finished at one time under the driving of main transport device.
l There is a hydraulic protection system near the bottom rolls. It is the biggest difference between pre-straightening machine and precision straightening machine.
Remark: there is hydraulic cylinder +piston body. The hydraulic oil controls the pressure and action, to protect the straightening roller if any suddenly accident.
The hydraulic cylinder stroke is about 20mm( more or less).
l There is a V-type guide bushing ,which can ensure raw materials smoothly .
l Overloading protection device & scram botton.
l Sound in running is about 105db. Generally, during the main machine is running, only very slight sound. Only when the material fall down on the loading and unloading table , it can cause bigger sound.
1 The equipment should be designed and manufactured strictly as the relative standard, technology agreement, etc.
2 The System will be guaranteed for Performance, Workmanship & Material of Construction for a period of 12 months from the date of commissioning or 18 months from the date of last dispatch, which ever, is earlier.
3 Remark：Straightening rolls ----material( SKD11)，hardness:60-62HRC
1.Our guarantee for straightening rolls is 6 months( Internal standard ). It service life is about 1-2 years. It depends on the operation and maintenance. Besides, for one set rolls, its curvature can be reconditioned three times at most.
2. Because of the long production time, generally, we suggest our clients to buy one extra set straightening rolls. ( The following rolls is only for reference.)
3. Rolls drawing: We COULD NOT supply rolls drawings. In this issue, we are so sorry that we could not make any concession. But we can give the template of the straightening rolls and tell some skills of survey –draw straightening rolls. Some of our clients use this method to prepare straightening rolls by themselves.
