The Lefthand Scrolling Photos: Function units and components of Wuxi JACK Angle Iron Straightening Machine
For achieving on satisfactory straightening effect on Angle Steels:
1) Input and Output Conveyors: There are conveying roller tables being installed at front and rear ends of the machine main frame. The conveyors can be swapped as input or output function at will anytime, if it is necessary to change;
2) Manual Push on Angle Steels: Both input and output of conveyor roller tables are idle running. So, after loading workpiece Angle Steels onto conveyors, operator need to push it forward into central working area inside the machine main frame.
1) Importance: This is the key step in achieving on proper straightening effect from the machine;
2) Idle Test: First, validate on downward stroke of each piece of straightening roller, in the way of idle running (No Angle Steel sent in);
3) Wuxi JACK Empirical Data: For recommended downward moving stroke of each piece of straightening roller, for each model of the Angle Steel Straightener machine, there is rule of thumb accumulated by Wuxi JACK engineering team for over 15 years. We share with customers these precious data as part of technical documents, when making delivery on each model of the machine;
1) Intuitive Operation: Downward stroke of each piece of straightening roller can be manipulated individually;
2) Working Lamp: During operation process, there is indicating lamp illuminating on top of the machine mechanical main frame, thus cautioning working staff to be at certain distance away from the machine.
Here we take Wuxi JACK ASM63 model machine as an example to explain:
1) Straightening Rollers Quantity and Arrangement: As shown in the above 1st photo, there are 5 pieces of downward acting straightening rollers, and 4 pieces of bottom assembled stationary straightening rollers, in a set of Wuxi JACK ASM series Angle Steel Straightener Machine;
2) Workpiece Going Through Way: The working parts Angle Steel come into mechanical main frame of the machine, either from its righthand or lefthand side. Shown in below:
In below design sketch, Angle steel goes into the machine for being straightened, moving in the direction of from right side to left side: (Fig.1)
3) Rule of Thumb on Critical Process Parameters:
a) Wuxi JACK has rich accumulation of empirical data, on suggested downward stroke of each piece of the 5 downward acting straightening rollers, for straightening on each specification of Angle steel. This is very valuable data for customer, and can help customer acquiring on satisfactory operation performance of the Angle Iron Straightening Machine. For example:
b) Empirical data chart of Wuxi JACK ASM63 model Rolled Angle Straightening Machine, for downward moving stroke of each piece of straightening roller, for each specification of Angle Steel: (Fig.2)
4) Fulfil Satisfactory Straightening Effect: You can find that with the Angle Steel going forward through central working unit of our Angle Steel Straightener Machine, it gradually grows flattened. The straightening target on Angle Steel can be attained automatically and effectively.
1) Drive and Transmission on Downward Straightening:
a) As shown in the above 2nd photo, the downward movement of straightening rollers are transmitted with worm gear reducer, which are installed at top of mechanical main frame of the machine:
b) Vertical view on worm gear reducers installed on central function cell of Wuxi JACK Angle Steel Straightening Machine: (Fig.3)
2) Drive Force Source on Straightening Rollers Downward Movement:
This is the most important force for Angle Steel straightening operation:
a) For light to medium models ASM63/ 100/ 130, the power on turning worm gear reducers is realized with manual turning handwheels by operator;
b) For large heavy duty models ASM160/ 200, the power on turning worm gear reducers is driven with A.C. motors and reducers --- Manual turning can not attain on such job.
1) Significance and Function: Downward stroke of straightening rollers determine on straightening effect and efficiency on Angle Steel, which can be observed by operator conveniently:
2) As shown in the above 3rd photo, being pasted onto front wall of machine main frame, alongside each piece of the downward moving straightening roller, there is a piece of indicating ruler indicating on downward stroke:
Indicating ruler on downward moving stroke of straightening roller: (Fig.4)
3) Operation: Before straightening operation, operator can check on actual downward stroke of each of the straightening roller with this ruler, and make adjustment accordingly if necessary.
1) Finally, as shown in the above 4th photo, the straightening operation on workpiece Angle Steels is implemented in working cell, which is right inside mechanical main frame of the machine;
2) Side view on central operating unit, straightening and conveying Angle Steel out of the machine: (Fig.5)
One set of Wuxi JACK ASM model machine for Angle Steel straightening is composed of 4 main systems of:
1) Motor Drive Through Straightening Cavity: As shown in the above 1st photo. In ASM models Rolled Angle Straightening Machine, sending forward of workpiece is driven with A.C. cycloidal motor reducer, and transmitted with chain and sprocket;
2) Sending Together with Straightening: Working parts (Angle steel) moves through straightening unit inside cavity of mechanical main frame, and got straightened simultaneously;
3) Manual Loaded onto Conveyor: Meanwhile, on the conveyors, the workpiece Angle Steel is pushed forward toward straightening cavity by manual job, in conventional models of the machine (Motor drive sending is available);
4) For safe operation purpose, transmission chains are covered with steel cover, and painted with alarming bright yellow color, to avoid operator hands being entangled.
1) Appearance: As shown in the above 2nd photo, which was taken from lateral side of the central working zone: Straightening working mechanism of each pair of the straightening rollers, are integrated into cavity of the machine main frame;
2) Formation: The pair of downward straightening rollers and bottom supporting rollers form the straightening couple, totally 5 pairs in one set of the machine. With moving forward of Angle steel through this cavity, the Angle steel got flattened out in high efficiency and effect.
1) Role: As shown in the above 3rd photo. Straightening rollers are the most critical function element in any set of the machine, for fulfilling on high standard Angle Steel straightening effect;
2) Material and Process Technology: In Wuxi JACK produced machine for Rolled Angle straightening, every piece of straightening roller is made of Alloy Steel, precisely machined, and treated with strictly managed heat treatment: Surface tempered, and integral quenched, to guarantee on its strength and toughness.
1) Drive Form: As shown in the above 4th photo. In the machine, input and output conveyor roller tables are idle form, which means Angle steel conveying are pushed by operator forward;
2) Movement Guide: There are guiding rollers distributed along the entire length of conveyors, to facilitate Angle steel being pushed forward smoothly.
From customer point of view, the Max. sizes of Angle steels that can be straightened, the machine can be grouped into below 3 categories of:
1) Conventional light to medium duty ASM63/ ASM100/ ASM100 models;
2) Economical version light duty ASM63 model;
