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

1. General Introduction on RH1000 Strip Edge Rounding Machine:

1) Background: The attached photos show a set of Wuxi JACK RH1000 model Strip Edge deburring and Rounding Machine, which is applied for being used in Bridge Construction Industry;

2) Development: Like other product family, RH1000 is the smallest standard model and also the starting point of our development on RH series machine. We develop it based on technology experience on welding equipment research and special characteristic of plate rounding operation;

3)  With years of accumulation, RH1000 model is a very mature and developed product, and one of the most popular models.

2. Structure and Main Units of RH1000 Automatic Strip Edge Trimming Machine:

1) Composition: Please check attached photos. The RH1000 model machine consists of:

a) One set of mechanical main body; 

b) Input and output conveyors roller table;

c) Hydraulic pump station, its control valves and oil hoses;

d) Electrical system and control board, operating panal and pendant;

2) Mechanical Main Frame of RH1000 Edge Rounding Machine: (Fig.1)

This is mainly composed of:

a) Solid base bed for central working area;

b) One set of stationary and one set of movable edge rounding units respectively, deployed at left and right side of the machine body;

c) Horizontal guiding unit, for alignment on edge rounding rollers, accommodating on different size of working parts;

d) Side fending roller for alignment of working parts in the machine;

3) The solid base bed is welded into box structure, of which its rigidity and strength has been calculated and validated by Wuxi JACK engineering team, during design and production period of the Edge Trimming Rounding Machine.

3. Rounding Operation Steps in RH1000 Strip Edge Deburring and Rounding Machine:

1) Stationary and Movable Rounding Rollers in Edge Rounding Machine:

a)  The stationary edge rounding unit drives its bottom rounding roller into revolve, under the drive of cycloidal motor reducer through coupler, leading and driving workpiece plate being rounded continuously:

b) The movable edge rounding unit also drives its bottom edge rounding roller into revolve, driven under another set of cycloidal motor reducer by means of coupler:

c) Besides, the movable edge rounding unit can move horizontally along guiding bush, under the drive of oil cylinder, which in turn adjust on edge rounding roller span, based on different width of steel plate in the Edge Rounding Machine;

2) Top and Bottom Rounding Rollers in Edge Trimming and Rounding Machine:

a) Quantity of Edge Rounding Rollers: 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 rounding rollers in the form of two pairs, in one set of the RH1000 model machine: 

Top and bottom one pair of edge rounding rollers in RH1000 model machine: (Fig.4)

b) 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 position edge rounding rollers into rotation. The pieces of bottom edge rounding rollers are driven with cycloidal gear motors and reducers:

c) Degree of Freedom: Comparatively, in Edge Deburring and Rounding Machine, the two pieces of top position 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 for machining, driven with corresponding hydraulic oil cylinders; And in terms of revolve, they are of idle type, driven with its counterpart of driving section bottom position edge rounding rollers;

d) Slant Edge Rounding Capability: Still further, in Wuxi JACK Edge Rounding Machine, the two pieces of top position edge rounding rollers can also move in inching mode, in horizontal direction, driven with another set of hydraulic cylinder, making the edge rounding rollers being pressed against rounding edges of workpiece plate firmly, even this rounding edge is slant in certain degrees:

3)  In this way, all function cells of the machine work together, realizing the deburring and edge rounding operation and effect in the RH1000 strip model machine;

4)  Please note here we do not mention the downward pressing rollers, as introduced in the product models of RH1500, RH2000 and RH3000. This unit is not equipped in RH1000 model machine, because the workpiece plate width of 1000mm and less does not entail this downward pressing unit, for keeping on flatness of narrow plate surface..
