- the invention relates to a rotary apparatus for the rotary forming of various formations and openings in a sheet metal work piece.
- the apparatus provides a means of positioning the openings, and a means of temporarily skipping an opening so as to leave a greater length of sheet metal, across which the cut may be made.
- the work piece (W) has a central web (10), and two side edge bends (12) and (14).
- the central web (10) is formed with a series of openings (16). These openings, in this case, are of generally triangular shape and the orientation of each triangle alternates along the length of the web.
- struts (18) of sheet metal are defined between the adjacent openings (26). These struts (18) form a generally zigzag or diagonal shape along the length of the work piece (W).
- Edge flanges (20) are formed around the openings (16).
- the longitudinal side edge bends (12) and (14) are formed lengthwise continuously along the length of the work piece (W).
- One such bend may be sufficient or in other cases, there may be two or three such bends to provide greater strength or for various different applications.
- one of the side edges may be bent outwardly to form a hook (22) as shown in phantom.
- a hook (22) is used in the formation of composite concrete and stud building panels.
- the embedment formations (22) are used when forming thin shell concrete panels to enclose a building.
- the studs or work pieces (W) are being embedded at spaced intervals for example 16" or two feet apart along the length of a panel, and upper and lower work pieces are also associated from a rectangular grid.
- FIG (1) and (2) illustrate a rotary apparatus (30).
- the rotary apparatus (30) comprises upper and lower main rotor assemblies (32) and (34).
- Each rotor has two die carriers (36) in this embodiment.
- Each die carrier (36) supports a die (38).
- Dies (38) are similar in most respects to conventional male and female dies used in stationary presses i.e. presses which reciprocate vertically but do not rotate.
- Each of the central rotors (32) and (34) in this embodiment, comprises a relatively slender central shaft portion (40), and two massive end bearing shafts (42).
- Each of the end bearing shafts (42) is mounted in a respective bearing systems (44) , and the bearing systems (44) are mounted in end plates (46) and (48) .
- End plates (46) and (48) will typically be mounted on bases (50) so that they may be placed in position in a production line.
- the upper and lower rotors (32) and (34) are coupled together by means of a lower drive gear (52) mounted on an end extension (54) of lower rotor end bearing shaft (42) , and an upper gear assembly (56) mounted on an end extension (58) of upper rotor end bearing shaft (42).
- the lower rotor end shaft extension (54) is adapted to be connected to any suitable prime mover (60) and gear box.
- the prime mover in this case will be a direct current electric motor ( Figure 26).
- the motor (60) will be of the type having a speed control (62) so that its rotational speed may be precisely controlled and varied.
- Speed control (62) in turn is controlled by a CPU.
- the upper gear assembly (56) comprises a main gear portion (64) and an outer back lash compensator gear (66).
- the back lash compensator gear (66) may be adjustably rotated relative to the main gear portion (64) and fastened so as to eliminate any back lash between the upper gear assembly (56) and the lower drive gear (52).
- Each of the four end bearing shaft (42) is formed in essentially the same manner as shown in Figure (2), apart from the shaft extensions.
- Each of the end bearing shaft (42) is provided with two bearing recesses (68), spaced apart angularly around the axis of each rotor by 180°. Within each bearing recess (68) there is a bearing or bushing (70) , which is held in position by a suitable cap.
- Each of the die carriers (36) in Figures 5, 6 and 7 is provided with an end stub shaft (74), at each end thereof. The end stub shafts (74) are received in the bearings (68) in the bearing recesses (68) of the end bearing shaft portions (42) . In this way, each of the die carriers (36) is swingable about the axis extending between the two stub shafts (74) .
- Each die carrier (36) is formed along its length with a generally planar die receiving area (76) in Figure 5, facing outwardly with respect to the rotors (32) and (34). On the reverse side of each die carrier (36), a generally convex profile (78) is formed, for each die carrier (36).
- Each of the upper and lower rotors (32) and (34) will carry two separate die carriers (36), each of which is adapted to receive a forming die (38) thereon.
- the invention is not however restricted to the use of two die carriers per rotor. Four die carriers have been used in same cases.
- the two rotors rotate, in opposite directions, one being clockwise and the other anti ⁇ clockwise, being connected by the gears (52) and (56) .
- the upper and lower dies (38) on the die carriers (36) will thus be brought into registration with one another at approximately the closest point of the two rotors (32) and (34), ie at about 180 degs and 360 degs respectively, and will then progressively move away from one another.
- the die carriers will be farthest away from one another at approximately 90° and 270°.
- the dies (38) on the die carriers (36) on the upper rotor (32) will usually be the male dies, and the dies (38) on the lower rotor (34) will usually be female or recess dies.
- Portions of sheet metal which are actually blanked out of the sheet metal workpiece will form waste or what are known as "slugs", and those slugs will remain temporarily in the recesses of the dies (38) on the lower rotor (34) and will be ejected by suitable slug ejector pins (80) to be described below.
- Die ejector pins (80) are operated by transverse ejector rods (82) mounted in the lower rotor (34) and having end portions (82) extending outwardly to one end of the lower rotor (34).
- the inner ends (84) of the rods (82) are formed with an angled surface (86), and when the rods (82) are moved inwardly, the angled surfaces (86) engage the ejector pins (80) and cause them to eject a slug from the die (38).
- the rod (82) is operated in the reverse direction by springs and the ejector pins (80) are also retracted by springs. Operation of each of the die ejector rod (82 ) in sequence is achieved by means of an operating roller (88) mounted on end plate (48 ) Fig 2. Die Carrier Guidance
- the guidance of the die carriers (36) includes first cams (90) and second cams (92) are mounted on end plates (46) and (48) adjacent to each end of each of the rotors (32) and (34).
- First cams (90) are one piece plates formed in a generally oval shape as shown.
- the second cams (92), Figure (12 ), (13) and Figure (14 ) comprises a first generally oval shape centre cam portion (94), and a second semi-arcuate cam portion (96), Figs 15, 16 and 17.
- the oval portion (94) and the semi-arcuate portion (96) define a roller channel (98) between them, and at each end of the space there is what is in effect a "gate" (100) and (102). The function of the gates will be explained below.
- the first and second cams (90) and (92) and arcuate portions (96) are found on both right and left side bearing plates (46) and (48), arranged as mirror images of each other, and also arranged in registration with both the lower rotor (34) and the upper rotor (32). There are thus, four first cams (90) and four second cam portions (94) and four arcuate portions (96).
- Each of the die carriers (36) is provided with leading guide rollers (104) and trailing guide rollers (106), arranged in registration with the leading and trailing edges of their respective die carriers (36), and spaced equally on opposite sides of the central axis of the die carriers stub shaft (40).
- the leading guide rollers (104) are mounted on shafts (108), which displace the leading guide rollers outwardly with respect to their respective die carriers (36).
- the trailing guide rollers (106) are mounted on shafts (110), which position the trailing guide rollers (106) more closely adjacent to their die carriers (36), than are the leading guide rollers (104).
- leading and trailing guide rollers The displacement of the leading and trailing guide rollers in this way permits the leading and trailing guide rollers to ride on respective first and second cams (90) and (92), and thus follow leading and trailing guide paths which have different profiles from one another, being defined by the respective first and second guide cam (90) and (92).
- first and second guide cam 90 and (92)
- the die carriers (36) will be rotated around 360 degrees with their respective leading and trailing guide rollers (104) and (106) engaging the respective first and second cams (90) and (92).
- the guide paths defined by the leading and trailing guide rollers (104) and (106) will cross twice in each 360° revolution. The cross over of these two paths occur at the gates (100) and (102) defined between the second cam plate (94) and the semi-arcuate cam portion (96).
- the semi arcuate cam portions (96) are formed with additional guidance bars (112), for the leading and trailing guide rollers, at the point of closure and openings of the die carriers, shown in Figures 15, 16 and 17.
- Such guide bars (112) are formed with two upper and two lower shallow semi-arcuate guide surfaces (114) and (116), which are oriented to engage the leading and trailing guide rollers (104) and (106) respectively from the point just prior to closure, and continue during closure, and to release upon opening.
- Such guide bars (112) are formed integrally with semi arcuate cam portions (96) and are mounted along side the first and second guide cams (90) and (92) as shown in Figure (19).
- the lower and upper rotors (32) and (34) rotate in opposite directions, as shown for example by arrows in Figure 1 , and a sheet metal workpiece indicated as (W) passes between them.
- their respective lower and upper die carriers (36) will be rotated, and in sequence pair of lower and upper die carriers (36) will approach to contact the sheet metal.
- they close the dies (38) will punch it and/or form it, and then open again separating away from each side of the sheet metal (W).
- the linear speeds of the die carriers (36) will vary slightly and will not be precisely matched to the linear speed of the sheet metal which is moving at a constant speed.
- the die carriers (36) Just prior to closure on the sheet metal, the die carriers (36) will be moving in a linear manner at a slower speed. At the top and bottom dead centre positions of the rotors (32) and (34) 180 degs and 360 degs, the linear speed of the die carriers will then match the linear speed of the workpiece (W). The linear speeds of the carriers (36) will then slow down relative to the workpiece as they open again.
- the motor (60) is controlled through the speed control (62) and the CPU so as to momentarily speed up the rotation of the lower and upper rotors (32) and (34) at a point just prior to closing, and then progressively slow down the rotation of the rotors as the rotors bring the die carriers (36) to bottom and top dead centres, and then the motor once again speeds up the rotors as the die carriers open.
- the speed control (62) then functions to return to the motor to its regular speed, until the next pair of die carriers (36) is just approaching the closing location.
- This control feature also enables the rotors (32) and (34) to be momentarily stopped or skipped, to provide for a gap between the formations in the sheet metal workpiece. Studs must be made in specific lengths. At the top and bottom end of each stud the metal must be unbroken by any opening. By means of programming the CPU, the motor can be momentarily stopped, at a point where for example the die carriers are positioned approximately 90° and 180° on either side of top and bottom dead centre. At this point, the sheet metal workpiece (W) will be able to pass freely between the rotors (32) and (34). The sheet metal workpieces will normally be cut to desired lengths by a suitable form of shear (not shown) located downstream of the rotor (32) and (34). The timing and operation of the shear will take place in timed relation to the "skipping" of openings being formed in the workpiece to make the desired lengths.
- a suitable form of shear not shown
- a further feature of the controllability of the motor controlling the speed of rotation of the rotors (32) and (34) is that it enables variations to be made in the spacing of the centres of the opening and formations formed in the workpiece (W).
- the CPU is reprogrammed to operate the rotors (32) and (34) at a sufficient speed, between top and bottom dead centres, with brief pauses while the die carriers are at the 90° and 270° position.
- an open sided rotary apparatus in which the rotors are supported at one end only, leaving the other end of the rotors unsupported.
- the basic formation of the rotors (32) and (34) and the die carriers (36) all substantially the same as described above, with the exception that the die carriers (36) will be provided with leading and trailing guide rollers , and cams and cam portions only in one end plate
- the outward ends of the lower and upper rotors (32) and (34) will be supported by massive cross beams (120 ) and (122 ), and support arms (124 ) and (126 ), providing bearings for the outer end of the rotors (32) and (34).
- a metal workpiece (W) may be placed in position through the open side of the apparatus as shown in Figure 21 , and the formations will be made, by the rotors and die carriers and dies in essentially the same manner as described above.
- a swing arm or bridge (130) may be swingably mounted on each of the semi-arcuate cam portions (96) .
- the bridge (130) is swingable between open and closed positions and guides the leading and trailing guide rollers (104) and (106) as they transition from contact with the semi-arcuate cam portions (96) to the guidance bars (116) .
- the bridge (130) has a lobe (132) which extends into the path of the trailing guide roller (106).
- a spring (134) connects between bridge (130) and guide bar (112).
- Figs 25 and 26 show the bridge in two positions, namely open , in the upper bridge, and closed in the lower bridge.
- Spring (134) biasses the bridge (130) into the closed (lower) position as shown in Fig (25) , and permits it to swing open (upper) in Fig 25 when required for either forward, or reverse rotation.
