Pipe straightening press

(TDW98Y-1250/1422*12200)

Features:
Gantry moving straightening machine.
Main parts consists of over-length working table of fixed-type, moving frame of gantry type, upper die, movable V-shaped support ,hydraulic system and electrical system.
1. Two groups V-shaped lower die of variable position on the working table to adjust mechanically to left or right. 2 groups lifting rotating rollers and 3 groups lifting conveying roller in the middle of working table.
2. The main pressure-head is equipped on the gantry. The pressure-head can straighten for over all bar stock at 360° round so that the straightening bar stock meets its requirements.
3. The main hydraulic system is located in top of machine frame to control the pressing of main pressure-head. Auxiliary hydraulic system is located at side of working table and it control rotating and lift of conveying roller, to meet requirements of  360° rotating and left-right conveying of bar stock.  
4. This machine has  the function of inching, single and keeping pressure, which can meet the requirement of work-piece straightening.
5. Rotating roller of straightening machine ascends to hold up and rotate the  work-piece to the position where the high point of straightening aims at 12 o' clock position. At the same time, all of 4 groups conveying roller ascend a certain height under the rotation roller.
6. Rotating roller of straightening machine falls to carry the work-piece on the conveying roller. The conveying roller rotates to carry the part of covering straightening high point to between the  2 V-shaped lower die. The work-piece is laid on 2 V-shaped lower die when Conveying roller falls.
7. Move the gantry  so that the pressing-head aims straightening high point of work-piece. Then the gantry is locked. The main cylinder of straightening machine pull upper die down to straighten the work-piece. The work-piece is straightened step by step until it meets requirements.
8. Main cylinder of straightening machine returns drawn upper die.

9. The process repeats until the overall length of work-piece is straightened around 360°.
10. To survey the linearity of work-piece by seeing or setting a line. If the linearity is in excess of the standards, the work-piece will straighten again until it meets the requirements.
11. After straighten, the rotating roller of straightening machine ascend to hold up the work-piece. At the same time, all of 5 groups conveying roller go up to a certain height under the rotation roller.
12.Rotating roller of straightening machine goes down to lay the work-piece on conveying roller.
