RH-1000 High Quality Strip Edge Rounding Machine for Bridge Industry

A. Usage and Application of RH800 and RH1000 Strip Plate Edge Rounding Machine:

1. Applied Industry: The attached photos show a set of Wuxi JACK RH1000 model Strip Plate Edge Deburring and Rounding Machine, which is applied for being used in T Beam/ Shipbuilding/ Bridge Construction Industry;

2. Development: Like other product family, RH1000 is the most popular standard model, and also the starting point of Wuxi JACK development, on RH series machine. We develop the machine on sheet metal edge rounding, based on technology experience on welding equipment research and special characteristic of plate edge rounding operation;

3. Capability of RH800 and RH1000 Strip Plate Edge Trimming Machine:

1) Function: This machine rounds the 4 corners of sheet metal, especially steel plate, from original sharp angle, to smooth and round angle of R2.5mm radius;

2) Great Benefit: In this way, the edge rounded plate grows friendly for handling, operator hands will not be pierced; Besides, painting can have far more better adhesion on corners of steel plates, thanks to its round smooth corners;

b) A piece of small width steel plate, being rounded with R2.5mm corner, from Wuxi JACK RH800 model machine: (Fig.2)

4. With years of accumulation, RH1000 is a very mature and developed model of high efficiency equipment on plate edge trimming. The edge rounding operation speed can be 7,200mm/min.

B. Structure and Main Units of RH800 and RH1000 Automatic Strip Plate Edge Deburring and Rounding Machine:

1. Main Units of Small Model Strip Plate Edge Trimming and Rounding Machine:

As shown in the attached photos, one set of RH1000 and RH800 model machine mainly consists of:

1) Integral open structure mechanical main body;

2) Input and output conveyor;

3) Hydraulic station, with numerous oil cylinders;

4) A.C. motor reducers, for driving on conveyors roller tables, and transmission rollers;

5) Gas cylinder drive edge rounding scrap blowing off units, and blue color air tubes;

6) Electrical system and control box:

2. Mechanical Main Body of Strip Plate Edge Rounding Machine:

Is mainly composes of:

1) Stationary solid base bed, for installing on central working area of edge rounding operation;

2) Edge Rounding Mechanisms: One set of stationary and one set of movable edge rounding units respectively, deployed at left and right side of machine base bed;

3) Horizontal guiding unit, for alignment on edge rounding rollers, accommodating on different widths and thickness of sheet metal plate;

4) Side fending rollers, for alignment on working parts;

3. Integral Bed: The dark color solid base bed is welded into durable box structure, of which its rigidity and strength has been fully calculated and validated, during design and production period of sheet metal steel plate Edge Rounding Machine.

C. Edge Rounding Operation Steps in RH1000 Strip Plate Edge Trimming Machine:

1. Stationary and Movable Edge Rounding Rollers in Strip Plate Edge Rounding Machine:

1) The stationary edge rounding unit drives its bottom position edge rounding roller into revolve, under the drive of A.C. cycloidal motor reducer, through coupler, driving the steel plate being edge rounded continuously;

2) The movable side edge rounding unit also drives its bottom position edge rounding roller into revolve, under the drive of another set of A.C. cycloidal motor reducer, by means of coupler:

3) Based on Plate Width: Besides, the movable edge rounding unit can slide horizontally, along high precision guiding bush, under the drive of oil cylinder, which in turn adjust on left and right edge rounding roller span, based on width of sheet metal plate in the machine;

2. Top and Bottom Position Edge Rounding Rollers in Strip Plate Edge Trimming Rounding Machine:

1) Arrangement: Both the stationary and movable edge rounding units have one piece of top and one piece of bottom roller respectively, which work in pair. Or, in other words, there are totally four pieces of edge rounding rollers in the form of two pairs, in one set of RH1000 model machine:

The left and right 2 pairs (4 pieces) of edge rounding rollers, in Wuxi JACK RH1000 model machine: (Fig.6)

2) Motion and Drive: The two pieces of bottom edge rounding rollers are fixed in terms of vertical movement, and is of driving type in terms of revolve, driving the two pieces of top edge rounding rollers into revolve. The 2 pieces of bottom edge rounding rollers are driven with A.C. cycloidal gear motors and reducers, on its revolve motion:

3) Comparatively, in RH1500 to RH3000 larger models machine, the two pieces of top edge rounding rollers can be moved up and down, as well as leftward and rightward, to be suitable for various thickness and width of workpiece plate, driven with corresponding hydraulic oil cylinders; And in terms of revolve, they are of idle type, driven with its counterpart of driving section bottom edge rounding rollers;

3. Edge Rounding Operation on Slant Edge Plate in Edge Rounding Machine:

1) Oblique Side Plate: In practical use, we can imagine that, not all workpiece plates have perfect straight edge. In other words, corner of steel plate may not in 90° right angle, posing challenge on edge rounding operation. So, how to deal with it?

2) Wuxi JACK Measure: Still further, in Edge Trimming Machine, the two pieces of top position edge rounding rollers can also be adjusted in movement in inching mode, along horizontal direction, under the drive of another set of hydraulic cylinder, making sure the edge rounding rollers pressing against 4 corners of steel plate firmly, even this edge rounding edge is slant in certain degrees:

3) Workpiece plate of slant corner, to be trimmed in Wuxi JACK RH models Edge Deburring and Rounding Machine: (Fig.8)

4) Thus realizes the deburring and rounding operation in RH series machine;

4. Please note here we do not mention the downward pressing rollers. This unit is not equipped in RH1000 and RH800 small models machine, because the workpiece plate width of 1000m and less does not entail the issue of middle protrusion, during edge rounding operation.
