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.
Two groups V-shaped lower die of variable position on the working table to adjust mechanically to left or right. 2 groups lifting rotatingrollers and 3 groups lifting conveying roller in the middle of working table.
The main pressure-head is equipped on the gantry. The pressure-head can straighten for over all bar stock at 360°round so that thestraightening bar stock meets its requirements.
The main hydraulic system is located in top of machine frame to control the pressing of main pressure-head. Auxiliary hydraulic systemis located at side of working table and it control rotating and lift of conveying roller, to meet requirements of 360°rotating and left-rightconveying of bar stock.
This machine has the function of inching, single and keeping pressure, which can meet the requirement of work-piece straightening.
Rotating roller of straightening machine ascends to hold up and rotate the work-piece to the position where the high point ofstraightening aims at 12 0′ clock position. At the same time, all of 4 groups conveying roller ascend a certain height under the rotationroller.
Rotating roller of straightening machine falls to carry the work-piece on the conveying roller. The conveying roller rotates to carry thepart of covering straightening high point to between the2 V-shaped lower die. The work-piece is laid on 2 V-shaped lower die whenConveying roller falls.
Move the gantry so that the pressing-head aims straightening high point of work-piece. Then the gantry is locked. The main cylinder ofstraightening machine pull upper die down to straighten the work-piece. The work-piece is straightened step by step until it meetsrequirements.
Main cylinder of straightening machine returns drawn upper die.
The process repeats until the overall length of work-piece is straightened around 360°
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 willstraighten again until it meets the requirements.
After straighten, the rotating roller of straightening machine ascend to hold up the work-piece. At the same time, all of 5 groupsconveying roller go up to a certain height under the rotation roller.
Rotating roller of straightening machine goes down to lay the work-piece on conveying roller.
