The specific embodiment

The present invention relates to a kind of slewing, be used for various structures of rotary forming and opening on sheet-metal work.

For example, form, between two openings, must realize Cutting Length so if opening passes the metal stud stamping-out.This equipment provides the device of locating aperture and has temporarily crossed opening to keep the device of bigger metallic plate length, strides across this metallic plate length and just can cut.

Workpiece W has central web 10 and dual-side bending 12 and 14.This central web 10 is formed with series of openings 16.In this case, these openings are normally leg-of-mutton, and each leg-of-mutton direction is alternately to change along the length of this web.Like this, the pillar 18 of metallic plate is defined between the adjacent opening 16.These pillars 18 form zigzag or oblique line shape along the length of workpiece W usually.Open 16 around be formed with flanging 20.

Length direction along workpiece W vertically forms vertical side bending 12 and 14 continuously.Such bending just may be enough, perhaps in other cases, can have two or three such bendings that bigger intensity is provided or be suitable for various application.In some cases, side can outwardly-bent formation crotch 22, shown in the dotted line among the figure.This crotch 22 is used to form the building panel (composite concrete and stud building panel) of mix concrete and stud.

The exemplary embodiments of flange is shown in the United States Patent (USP) 4602467.This patent relates to the stud of traditional C tee section.

With around building the time, use the structure 22 of this embodiment at the thin outer crust that forms concrete slab.Stud or workpiece W along the length of plate with for example 16 " or two feet interval embed, and top workpiece and following workpiece also combine with rectangular grid.

Workpiece W or metal stud have been illustrated in United States Patent (USP) 2088781 and 2167666.

Yet the stud of this general type only is a kind of in the multiple different product that can produce.Its speed of production height, forming accuracy is fabulous, and has flexibility, has different in width producing, different length and a heteroid workpiece.

Fig. 1 and Fig. 2 have described a kind of slewing 30.This slewing 30 comprises main rotating body component 32 and following main rotating body component 34.In this embodiment, each rotary body all has two mould bases 36.Each mould bases 36 supporting mould 38.Mould 38 all is similar with the traditional formpiston and the former that use fixedly punching press (promptly carry out up-and-down movement and be not rotated punching press) aspect most.

In this embodiment, each center rotary body 32 and 34 comprises relative elongated center axial region 40 and two thick and heavy end reach (end bearing shaft) 42.Each end reach 42 all is installed in separately the bearing system 44, and bearing system 44 is installed on end plate 46 and 48.Typically, end plate 46 and 48 is installed on the base 50, thereby they can be placed on the production line.Last rotary body 32 and following rotary body 34 link together by following driven wheel 52, this time driven wheel 52 is installed on down on the end extension (end extension) 54 of the end reach 42 of rotary body, and the assembly 56 that cogs is installed on the end extension 58 of end reach 42 of rotary body.The extension 54 of the end reach of following rotary body is suitable for being connected on any suitable prime mover 60 and the transmission case.Typically, in this case, this prime mover is dc motor (Figure 27).This motor 60 can be the motor with any kind of speed control unit 62, thereby its rotary speed can be accurately controlled and change.Speed control unit 62 is controlled by CPU again.The assembly 56 that cogs comprises main gear section 64 and outside backlash compensation gear 66.These backlash compensation gear 66 adjustable grounds are with respect to main gear section 64 rotations and fixing, so that eliminate at any backlash that cogs between assembly 56 and the following driven wheel 52.Except the extension of axle, four ends each in the reach 42 all forms in mode same as shown in Figure 2 basically.

Each end reach 42 all is provided with two carrying dimples 68, spends with 180 around the axle of each rotary body to separate angularly.All have bearing or axle sleeve 70 in each carrying dimple 68, it is supported in position by suitable top cover (cap).

Each mould bases 36 among Fig. 5,6 and 7 all is provided with end-journal (end stub shaft) 74 at its each end.This end-journal 74 be placed in the end reach 42 carrying dimple 68 in bearing 70 in.Like this, each mould bases 36 can be around the axle swing of extending between two axle journals 74.As shown in Figure 5, each mould bases 36 all is formed with the mould disposal area 76 that is generally the plane along its length direction, and it with respect to

rotary body

32 and 34 outward.For each mould bases 36, on the opposition side of each mould bases 36, be formed with common crowning (convex profile) 78.

Each of last rotary body 32 and following rotary body 34 will support two mould bases that separate 36, and each mould bases 36 all is suitable for ccontaining shaping dies 38 thereon.Yet the present invention is not limited to the occupation mode of two mould bases of each rotary body.Under identical situation, can use four mould bases.

Two rotary bodies rotate in opposite direction, and a rotary body turns clockwise, and another rotary body is rotated counterclockwise, and are connected with 56 by gear 52.Therefore, the upper die and lower die 38 on the mould bases 36 separate then each other gradually in the position (registration) aligned with each other of the closest approach (promptly respectively at 180 degree and 360 degree) of about two rotary bodies 32 and 34.Mould bases will be farthest apart in the position of about 90 degree and 270 degree.Mould 38 on the mould bases 36 on the last rotary body 32 is formpiston normally, and the mould 38 on following rotary body 34 normally former or die.

The metal plate sections that the actual stamping-out of sheet-metal work is gone out will form waste material or be called " metal derby (slug) ", and these metal derbies will temporarily be retained in down in the cavity of the mould 38 on the rotary body 34, and eject by the suitable metal derby knock pin 80 that below will describe.The knock pin 80 of mould moves by the horizontal knock-pin 82 that is installed on down in the rotary body 34, and has the end of an end that extends out to down rotary body 34.The inner 84 of this bar 82 is formed with angled surperficial 86, and when bar 82 moves inward, and angled surperficial 86 cooperate with knock pin 80 and metal derby is ejected from mould 38.This bar 82 moves in opposite direction by spring, and knock pin 80 is also withdrawn by spring.

The operation of the knock-pin 82 of each mould will realize by the manipulation roller 88 that is installed on Fig. 2 end plates 48 successively.

The mould bases guiding

The guiding of mould bases 36 comprises first cam 90 and second cam 92, and it is installed on the

end plate

46 and 48 adjacent with each end of each rotary body 32 and 34.As shown in the figure, first cam 90 forms an oval-shaped basically plate, shown in Figure 12,13 and 14, as can be seen, second cam 92 comprises the first oval-shaped basically center cams portion 94 and the second half arc cam part 96, shown in Figure 15,16 and 17.Elliptical section 94 and half arch portion 96 define roller passage 98 betwixt, and each end in this space all has actual " gateway " 100 and 102.The function of gateway will be described below.First cam 90 and second cam 92 and half arch portion 96 are positioned on right side loading plate 46 and the left side loading plate 48, and its mirror images of each other are provided with, and also are arranged to aim at following rotary body 34 and last rotary body 32.Therefore, have four first cams 90 and four second cam part 94 and four and half arch portion 96.

Each mould bases 36 is provided with all that leading it is arranged to aim at the leading edge and the trailing edge of they mould bases 36 separately to roller 104 and back molgogger 106, and with the opposite side spaced at equal intervals of the central axis 40 of mould bases axle journal.This is leading to be installed on the axle 108 to roller 104, and axle 108 is leadingly outwards setovered this about its mould bases 36 separately to roller.This back molgogger 106 be installed in the axle 110 on, this 110 make the back molgogger 106 be positioned at the position of more approaching their mould bases 36 to roller 104 than leading.Like this biasing leading to roller and back molgogger allow leading to roller and back molgogger be centered around separately first cam 90 and second cam 92 on rotate, and difform along having each other thus, by leadingly moving that separately first guide cam 90 and second guide cam 92 limit to path and back guide path.As can be seen, along with the rotation of rotary body 32 and 34, mould bases 36 will leadingly revolve three-sixth turn to roller 104 and back molgogger 106 with what match with separately first guide cam 90 and second guide cam 92.To in rotations of each 360 degree, intersect twice by the leading guide path that limits to roller 104 and back molgogger 106.This two paths crossing appears at by gateway 100 that limits between second lobe plate 94 and the half arc cam part 96 and 102 position.

This half arc cam part 96 location point closed at mould bases and that open is formed with and is used for leading additional guide rod 112 to roller and back molgogger, as Figure 15, shown in 16 and 17.These guide rods 112 are formed with two and go up shallow half arc spigot surfaces and two shallow down half arc spigot surfaces 114 and 116, its respectively before being about to closure, the closing course and the position that will open release is oriented to cooperate respectively to roller 104 and back molgogger 106 with leading.These guide rods 112 and half arc cam part 96 integrally form, and install along the side of first guide cam 90 and second guide cam 92, as shown in figure 19.

Operation

In when operation, last rotary body 32 rotates in opposite direction with following rotary body 34, for example shown in the arrow among Fig. 1, and therefrom passes with the sheet-metal work that W represents.Along with the down rotation of rotary body and last rotary body, their following mould bases and top mold frame 36 separately can rotation, and next, a pair of mould bases down and top mold frame 36 will be near to contact with metallic plate.Approaching along with them, mould 38 will carry out stamping-out and/or shaping to sheet-metal work, and then open and separate from each side of metallic plate W.Closed and open under when mould bases and top mold frame 36, minor variations will take place in the linear velocity of mould bases 36, and can not accurately mate with the linear velocity of the metallic plate that moves with fixed speed.Be about to before closure on the metallic plate, mould bases 36 will move with linear mode with slower speed.In 180 degree and the top dead-centre of 360 degree rotary bodies 32 and 34 and the position of bottom dead centre, the linear velocity of mould bases will be complementary with the linear velocity of workpiece W.Then, along with mould bases 36 is opened once more, the linear velocity of mould bases 36 will descend with respect to workpiece.

In order to overcome this problem, control motor 60 by speed control unit 62 and CPU, so that before being about to closure, rotary body 32 and following rotary body 34 temporary transient acceleration are rotated, along with rotary body makes mould bases 36 to bottom dead centre and top dead-centre, reduce the rotary speed of rotary body gradually, afterwards then, along with the unlatching of mould bases, motor makes rotary body quicken once more.Then, speed control unit 62 makes motor turn back to its fixedly rotary speed, till down a pair of mould bases 36 is about near closing position.Temporarily the rising gradually of this speed, descend afterwards, rise afterwards, descending afterwards produces according to increment, maximum increment appears at the position with respect to the maximum angular displacement of 180 degree and 360 mould bases of spending.In closure or opening process, along with the angular displacement of mould bases 36 gradually the location point before the contact reduce gradually to the dead point, each increment reduces gradually, then, putting from the dead point to the enable possition once more increases gradually.The increment of velocity variations is shown in the chart of Figure 24.Like this, make mould bases to move along bow-shaped route at the location point before being about to closed and unlatching, wherein its linear velocity is identical with the speed of sheet-metal work.

This control feature can also make

rotary body

32 and 34 temporarily stop or crossing, to provide the gap between the structure of sheet-metal work.Stud must be made length-specific.In the top and bottom of each stud, metal must not damaged by any opening.By to CPU programming, the positions that motor can be on the either side such as top dead-centre and bottom dead centre, mould bases is in about 90 degree and 180 degree temporarily stop.In this position, sheet-metal work W can freely pass between rotary body 32 and 34.This sheet-metal work can cut into desirable length by the cutter (not shown) of the suitable form that is positioned at

rotary body

32 and 34 downstreams usually.The timing of this cutter and operation are the time correlations that is formed at the opening in the workpiece with " crossing ", processing desirable length.

Another feature of the control ability of the motor of control

rotary body

32 and 34 rotary speed is: change in the distance between the opening that it can form in workpiece W and the center of structure.CPU is reprogramed, make

rotary body

32 and 34 between top dead-centre and bottom dead centre, move, when mould bases is in the position of 90 degree and 270 degree, have of short duration pause with enough speed.This will allow workpiece to pass through between the rotary body more or less, and mould does not contact and form structure with workpiece.

Other embodiment

In some cases, it is desirable to provide the slewing of open type, wherein, rotary body is only at one end supported, and the other end of rotary body is not supported.The another kind of form of this slewing is shown among Figure 21, Figure 22 and Figure 23.Except mould bases 36 is provided with leadingly to roller and back molgogger, and cam and cam part be only outside on the end plate, rotary body 32 with 34 and the essential structure of mould bases 36 basically with described above identical.The outer end of last rotary body 32 and following rotary body 34 by thick and

heavy crossbeam

120 and 122 and

support arm

124 and 126 support, provide bearing with outer end to

rotary body

32 and 34.

Like this, metal works W can pass the open side of equipment shown in Figure 21 and be placed in position, and can adopt with the essentially identical mode of above description and form structure by rotary body, mould bases and mould.

One side of workpiece can extend out between

arm

124 and 126.

This provides very big flexibility for the use of this equipment.

In some cases, it is desirable to the guidance system that provides different, to obtain the smooth conversion of arc cam part 96 from the surface to half of second cam 94.For this variation, as Figure 25 and shown in Figure 26, swing arm or bridgeware 130 are installed on each half arc cam part 96 swingably.This bridgeware 130 can open and closing position between swing, and contact from contact to be transformed into to roller 104 and back molgogger 106 with guide rod 112 with half arc cam part 96 along with leading, this is leadingly led to roller 104 and back molgogger 106.

Bridgeware 130 has protuberance 132, and it extends in the path of back molgogger 106.Spring 134 is connected between this bridgeware 130 and the guide rod 112.

Figure 25 and Figure 26 show the bridgeware of two positions, and promptly bridgeware is up opened, and below the bridgeware closure.

As shown in figure 25, spring 134 is biased in closure (below) position with bridgeware 130, and when the needs forward or reverse, allows it to swing to unlatching (top) position, as shown in figure 25.
