Referring now to accompanying drawing,, wherein, in all different views, with the part of same reference number TYP, more definite, referring to Fig. 1 a and 1b, reference number 10 total representatives are used for the feeding station of continuous feed band, and it comprises that one is wound with the roll coil of strip 11 of band thereon.The roll coil of strip 11 comprises that by one the driving mechanism 12 of driven roller 13 rotates.Aligning unit 14 comprises preferably staggered each other last backer roll 15 and following backer roll 15 ', any distortion, crimping or bending that these backer rolls may produce on band when being intended to remove on the roll coil of strip 11 winding strips.What align unit 14 downstreams is a feed unit 16, and it provides the continuous feed of band 111 and comprises last feed rolls 17 and the following feed rolls 17 ' with traditional structure.Operation with control module 18 usefulness electronic-controlled machine various pieces of traditional structure.Thus, the speed of roller members 13 is controlled by a lever arm 19 with a servo-actuated member 19 ', and this servo-actuated member straddles on the band 111 and with a potentiometer and links to each other, so that control the speed of roller members 13 by lead 18a.Schematically show a total loose degree control module that marks with reference number 20 in the drawings, maximum loose amount 111 in its control band " and minimum loose amount 111 '; this loose degree is essential owing to adopted continuous feed in feeding station 10; and in contrast; the stamping procedure in stamping station 40 then needs feeding band off and on, so that can go out the evil spirit lock when band stops.Loose degree control module 20 can have any traditional structure, and for example can comprise and to be connected to each other and to be fixed on firmly at its top with two vertical component 22a on the bottom of label 23 representatives and 22b.Therefore, to connect a limit switch 24 on the top of vertical component 22b, its switching mechanism is moved by a detection component 25 that is used for engaging with loose part that stretches out downwards, when loose part 111 ' reaches its predetermined minimum loose amount, make the switch motion in the switching mechanism 24, and give control module 18 with information by lead 24a, to accelerate continuous feed.Maximum predetermined loose amount is also detected by a for example metal sheet 26 by limit switch, this metal sheet insulate with respect to the earth and is contained on the preposition, preferably adjustable ground is contained on vertical component 22a and the 22b, and lead 27a and 27b are contained on vertical component 22a and the 22b.Band 111 usually by any conventional apparatus electrical ground, so that when loose part 111 " when surpassing maximum predetermined loose amount; band just makes plate 26 ground connection of originally insulating with respect to the earth; thus; the ground connection of plate 26 just acts on the control module by terminal box 28 and lead 28a, and continuous feed is slowed down.Thus, use to send the information of control module 18 to by

lead

24a and 28a and control the speed of

feeding station

10,11,12,13,15 and 16, to remain in the predetermined scope with loose by the speed that changes the feeding station lentamente.Certainly, also can adopt any other known layouts to go to carry out 25,24,24a and 26,28, the limitation function of 28a.One total index(ing) feed unit with reference number 30 representatives by one total with the oiling station of reference number 35 representatives to a total punching unit of representing with reference number 40 feeding band 111 off and on, this oiling station is pressed the upper surface and the lower surface that need lubricate bands from fuel tank 36 of making ide by pipeline 37 and arm 38 and 39.Therefore, oiling station 35 will be positioned as close to punching unit 40.Punching unit 40 comprises a drift member 41 and a fixing basic component 42, this basic component supports upright column ways 43 securely, and drift member 41 can reciprocally be supported on the ways by means of make holistic short supporting member 44 with it.The making ide (not shown) is contained in in two the bearing 45, and this bearing comprises making ide (correctly saying) (not shown), to obtain the preferably mechanical connection of magic lock.Making ide comprises four parts, and wherein two is following former formula member, and two is top with the perforating die member of any traditional mode by 41 actions of drift member.Therefore, when when the direction of feed of band is looked, the following former formula member of back directly is not bearing on the fixing basic component 42, but use the brute spring elastic bearing, but the following former formula member of front then directly is bearing on the fixing basic component 42, and the last perforating die member of front is also owing to getting in touch the reason spring-loaded that punching operation describes later on, this punching operation requires in succession blank to do the connection once more of part, so that further the band that punching press is come out is delivered to total distortion station of representing with reference number 50 (exactly) from stamping station.

Exactly, there are three axial locations at bending station or distortion station along the direction of the direction of feed from stamping station 40 to distortion station 50 perpendicular to band.Respectively the blank of mechanical connection that has sun preferably and a cloudy evil spirit lock configuration at fore-end and rear end part by means of the sliding component that can vertically move back and forth 52 and 53 of bottom, be suitable for the lateral sliding member 60 that moves back and forth along the slightly downward-sloping direction of side direction and 61 and the sliding component that can vertically move back and forth 70 on top around core member 51 distortion.Therefore, each

sliding component

52,53,60,61 and 70 all is made up of interconnected rigidly each other a plurality of parts of arranging vertically in a given sliding component, and the axial location on its quantity and the texturing machine is identical with the quantity of its textured surface.Lower slider member 52 is directed in ways 54, and lower slider member 53 then is directed in ways 55, thus, both sides in each sliding

component

52 and 53 all will be provided with ways, but, for convenience's sake, in some figure, only show one of them.Like this, sliding component 52 moves back and forth by the connecting rod 56 and 57 (Fig. 1 b) that links to each other with cam follower with 53, this cam follower moves along the suitable cam face of cam member, and all cam members are all synchronously driven with mechanical system in machine.Similarly, sliding

component

60 and 61 is activated by the execution member 64 that can swing and 65, the lower end of described execution member links to each other with 61 with sliding component 60 with 65a by connecting rod 64a, and its upper end then is provided with the cam follower that moves along the cam face of the cam 66 that is mechanically driven and 67.Each carries out

member

64 and 65 therefore can be around

fulcrum

64b and 65b swing.Last sliding component 70 is carried out member 72 actions by one, carries out it and moves back and forth, and this is carried out member 72 and operationally links to each other with the cam (not shown) that drives with mechanical system by a cam follower.

The mechanical connection of compression ring can be any known pattern, for example as United States Patent (USP) 5 the applicant, 001,816 and 5,185, described in 908 like that, has evil spirit lock configuration, but preferably as also more fully disclosed the sort of improved evil spirit lock configuration in the applicant's the application of examining that is entitled as " improved magic lock compression ring ", this application is submitted on April 17th, 1996, series number is No.60/015,700 (D/21569), and its theme will all be incorporated among the application herein.Total male portion branch with reference number 400 (Fig. 3 B, 3C and 3D) expression of this magic lock mechanical connection comprises a tongue 401 (Fig. 5) that stops with the head 402 that strengthens and is provided with two ledge portion 403 and 404 that are positioned at the side.Total concave portions with reference number 420 (Fig. 3 B, 3C and 3D) expression of this magic lock mechanical connection has the shape with 400 complementations of convex part.Although preferentially having selected for use on each different angle is the angle at right angle basically, so that the bearing-surface 431,432,433,434,435 and 436 along horizontal expansion to be provided, but side bearing face 437 in the scope of the head 402 that strengthens and the 438 supporting end faces 439 that will enter by the bearing-surface 440 and 441 of band fillet along horizontal expansion, described bearing-surface 440 and 441 has greatly improved the clamping ability of mechanical connection as what illustrate more fully in the aforementioned application of examining.In addition, the zone 410,411 and 412 that with dashed lines is pointed out will be subjected to the swaged forging effect, moving the material in the bonding pad of the bearing-surface that is bonded with each other 432,434 of horizontal expansion and 439, thus the mechanical connection that improves compression ring transportation and/or with it clamping ability when the fastening for example flexible pipe on pipe joint, minor axis etc., pipe spreader or analog.

All the other details of machine will be got in touch the operation of machine and be described.Therefore, a circulation of this operation comprises to be delivered to stamping station 40 off and on band and leaves stamping station and be sent to the distortion station, at this place, stamp out mechanical connection with preferred evil spirit lock configuration, and meanwhile index(ing) feed is in the state of resting, this circulation also comprises the adjacent convex cutting off and partly be connected magic lock mechanical connection again partly and concave portions, and the

sliding component

50,52,53,60,62 that will be explained in more detail later on and 70 periodicity move.But, should further point out, when on bending machine or texturing machine, making compression ring, need the same stage, i.e. the so much operation cycle of carrying out in order in core member 50 position in the axial direction.When sliding component has been represented with

reference number

52,53,60,61 and 71 in the schematic diagram of Fig. 1 b, each this sliding component comprises many parts that connect rigidly mutually of arranging vertically, and the number of these parts is corresponding to the axial position number along the core member on the different distortion surface with corresponding number.For the ease of understanding the operation of machine, in Fig. 7,8,9,10,11 and 12, will represent with the reference number of corresponding 100,200 and 300 series corresponding to the core member of first, second and the 3rd position and the various piece of sliding component.

Operation

Operation according to machine of the present invention is as follows.

By launching band from the roll coil of strip 11 and band 111 being sent from feeding station 10 continuously, the roll coil of strip by driving mechanism 12 and roller members 13 with continuous velocity action by control module 18 controls, thus this continuous speed itself again by straddle on the band 111 with its servo-actuated member 19 ' and the position of the lever arm 19 that links to each other with a potentiometer definite.Because the electronic circuit of control module 18 is to be known traditional of those of skill in the art, and does not become a part of the present invention, has therefore omitted detailed description thereof herein.The band 111 that is uncoiled from the roll coil of strip 11 continuously is sent to aligning unit 14, at this place, removes any distortion, crimping or bending, the band of delivering to continuous feed unit 16 with assurance is fully straight.The feed rolls 17 and 17 ' of feed unit 16 provides the continuous feed of band 111.Detect maximum loose amount 111 by plate 26 " and the loose degree control module 20 that detects minimum loose amount 111 ' by servo-actuated member 25 when the maximum or minimum loose amount of band surpasses preestablished limit, pass through

lead

24a and 28a with information back to control module 18.For the band length that makes each circulation institute feeding is all the same, this loose degree control must be arranged, so that the speed of the speed of continuous feed unit 16 and index(ing) feed unit 30 is got in touch.In other words, must be greater than the feed rolls 17 of operation continuously and 17 ' speed by lead 33 by the speed of the feed rolls 31 of control module 18 control and 33, resting during with the compensation punching operation.Total comprises a fuel tank 36 with reference number 35 oiling stations that represent, close punching unit 40 settings of near-earth as far as possible, it is used for by pipeline 37 and

arm

38 and 39 lubricating oil being delivered to the end face and the bottom surface of the band of feeding off and on, and its amount is decided according to the needs of making ide.

Punching unit 40 comprises a drift member 41 that moves back and forth, and it moves back and forth on upright column ways 43 by means of its short member 44, as in this punching unit of routine.Punching unit 40 further comprises a fixing basic component 42, and its upper support has upright ways 43.One bearing in two 45 that is bearing in securely on the basic component 42 includes making ide (correctly saying) (not shown), to realize being used for the preferably cutting of the mechanical connection of magic lock.Therefore, each cutting of the punching operation of this mechanical connection provides the evil spirit lock configuration of a spill in the rear end of band, and a kind of evil spirit lock configuration of convex is provided at the front end of band.For the blank that can will cut in stamping station with the feed unit 30 that can operate off and on be delivered to bending station or distortion station 50 from stamping station 40, must be in a given operation cycle when resting, couple together once more by two strip sections successively of punching operation cut-out.For this reason, making ide comprises the last perforating die member (not shown) that two following former formula part (not shown) and two match with separately following former formula member.Thus, when the direction of feed of band is looked, the following former formula member of back is with one or more brute spring elastic bearings, and simultaneously, the last perforating die member of last right front is also used spring-loaded.Like this, a pair of last perforating die member in back operationally directly links to each other with drift member 41, and last right following former formula member then directly is bearing on the basic component 42.The part of the magic lock configuration of the cutting-out that is being obtained by cutting when resting in a press cycle like this, connects again will be as partly being reconnected of schematically illustrating in Figure 14 once more.The part of evil spirit lock forces together and is shown in the step 2 of Figure 14, and it is finished by the effect of the brute spring of a pair of following former formula member in supporting back.The blank that Figure 14 shows the front in step 4 further is in distortion station and separating again at the blank of the back that step 2 partly reconnects.For this reason, originally one spring-loading plunger member or pin member are pressed on the next blank subsequently in the distortion station under the stage of resting at index(ing) feed, finish completely by plunger member on the sun evil spirit lock configuration that acts on next blank subsequently or pin member then and separate again, and next blank is subsequently pushed down by spring-loading plunger member or pin member, until now with the separation like this of reference number 111a representative at preceding blank by the fingers 80a shown in Fig. 2 A and the 3A, 80b, 80c moves along the direction perpendicular to direction of feed.Should be understood that, Fig. 1 a, 1b, 2A, 2B, 2C and 2D are the side views that axially obtains along core member 51, and Fig. 3 A, 3B, 3C, 3D and 4A are the planes of signal, thus in Fig. 2 A, 3A and 4A, in Fig. 2 B and 3B, in Fig. 2 C and 3C and in Fig. 2 D and 3D, the position of various piece is always corresponding.Therefore, at first, second and the 3rd position of machine, use reference number 111a, 111b and 111c represent blank, and the blank that is sent is represented with reference number 111d.On texturing machine, comprise a little slope,, and can not hindered because of running into bearing-surface so that next blank subsequently is increased to the level height of the blank of front in next feeding circulation in the feeding path of separation place fully again.The step 1 of Figure 14,2,3 and 4 is side views of signal, and the step 5 in Figure 14 is planes of signal.

Laterally moving of blank shown in the step 5 in Figure 14 is to be realized by three fingers 80a, 80b that can move back and forth and 80c, and they are with the primary importance of blank immigration on core member 51 of separating.In this primary importance, make the blank predeformation that finally will be formed compression ring, thereby accurately being met, its end makes the closed needed circular contour of magic lock mechanical connection.Can clearly be seen that in Fig. 2 a and Fig. 7 the first 151 of core member 51 is slightly oval, it has the profile of apple shape.The blank that originally partly reconnects separate fully with fingers 80a, 80b and the laterally mobile blank 111a that separates of 80c after,

lower slider member

52 and 53 side by side moves up basically so that have its textured surface that engages with

band

158 and 159 part 152 and 153 by one from zero through the path of 1,2,3,4 to Figure 15 position 5 with blank deformation.After this, having part 160 and 161

sliding component

60 and 61 partly engages with upwardly extending point-blank band basically with its textured surface that engages with

band

168 and 169, make band be deformed into position 6 ' through position 1 ', 2 ', 3 ', 4 ' and 5 ', at this place, the part 170 of last sliding component 70 just engages with band with its textured surface that engages with band 173 when moving down, and the end that will comprise the mechanical connection of evil spirit lock configuration is deformed into position 6 ".When all sliding components are all return, because material is flexible and by by the help at dimple 191a and the spring 192a among the 191b and the flexibly mounted L shaped fingers 190a of 192b and the 190b (Fig. 7) of fuse part 151, so the blank of predeformation will be back to position 6 rapidly.Short leg 194a and the 194b of fingers 190a and 190b determined the maximum protruding of these fingers.If necessary, the maximum of these fingers 190a and 190b is stretched out also and can be conditioned, and this will get in touch Fig. 9 afterwards and be described.

Fig. 2 A shows the position of sliding component when its retracted position at the beginning of the cycle.A circulation finish and blank when its end 6 take the primary importance distortion of the position of rebounding shown in Figure 15, make the blank that passes through predeformation like this move to second axial location on core member 51 from the primary importance on the core member 51 by means of fingers 81a, the 81b, 81c and the 81d that move back and forth.On this position, make blank 111b be deformed into circle, and the mechanical connection of closed evil spirit lock shape.Fig. 8 shows the position of part 252,253,260,261 and 270 when its extended position of sliding

component

52,53,60,61 and 70.In order to obtain making by means of the part 270 of last sliding component 70 the closed necessary overlap joint of mechanical connection configuration of magic lock, the mobile outline that inwardly enters its extended position of sliding component 60 moves prior to sliding component 61.Fingers 290 stretches out from its dimple 291 at first, so that spill evil spirit lock end is in above the convex evil spirit lock end, thus, when the part 261 of sliding component 62 arrives its positions of inwardly stretching out, inwardly promote fingers 290 with regard to the active force of resisting spring 292.Last sliding component part 270 moves down Shi Yiqi at it and is out of shape insert 274 closed evil spirit locks, with distortion and the closure of finishing compression ring.When sliding

component

52,53,60,61 and 71 when second circulation time of complete operation is regained once more, so distortion and closed compression ring are moved into the 3rd position of compression ring 111c from its second place by

fingers

82a, 82b, 82c and 82d.The compression ring 111d that this displacement from position 2 to position 3 of distortion and closed compression ring will originally be clamped on the position 3 simultaneously 3 is subjected to being sent after the swaged forging operation in the position at it, and this will describe afterwards in more detail.

3 (Figure 11) in the position, closed ring 111c is subjected to the swaged forging effect by means of the little dentation 378 on the insertion member 377 of little dentation 376 on the insertion member 374 of the part 370 of last sliding component 70 and insertion fuse part 351.These teeth will so be provided with, and produce so that swaged forging acts on the support rim 432,434 of horizontal expansion of regional inherent magic lock mechanical connections (Fig. 5) of with dashed lines 411,412 and 410 expressions and 439 the zone.As described in the applicant's the application of examining, this swaged forging effect has improved the clamping ability of compression ring widely, and the main contents of above-mentioned application will be cited as reference herein.

Figure 13 shows a total device of representing with reference number 500, and it is used for blank is clamped in its precalculated position on core member 50, so that the swaged forging effect is always carried out on the tram of magic lock mechanical connection.The device 500 be arranged in

Help the predeformation of compression ring on position 1 of mechanical connection closure to require that the compression ring of minor diameter is had different processing, this be because, in the case, the effect of coming to a point that the convex part that is connected by magic lock and the small curvature radius of concave portions cause has bigger meaning, and it is owing to be difficult to make the connection closure along the smaller opening of the inner periphery surface of band body part.In the case, may wish that in the position 1 predeformation contains an end with mechanical connection of evil spirit lock configuration, so that it is straight, then 2 closed straight evil spirits lock configurations in the position, the compression ring with closure is deformed into desired circle then.This work can for example be finished in another stage, so that whole manufacturing need have four operation cycle of four positions.But, thereby also can it be softened obtain good result because of being subjected to heat treatment about 400 ℃ in this case by making the material in the convex of compression ring blank end evil spirit lock configuration district and spill evil spirit lock configuration district.By so with material softening, can be easy to make mechanical connection closure with evil spirit lock configuration with softer material, but, this softer material will processed once more sclerosis when mechanical connection is actual closed, thereby described above just enough three locational three operational phases.

Because the only various piece of each sliding component of needs exchange, thereby machine of the present invention is very effective, might have the compression ring of different radial dimensions with same device fabrication.In addition, the speed of machine operation is very high, allows per minute to produce 55 compression rings.

All sliding components all mechanically move by the cam that drives with mechanical system, and sliding component also can be installed with roller bearing, to guarantee when it moves back and forth that in an operation cycle friction free slides.The different piece of sliding

component

52,53,60,61 and core member 50 also is provided with such surface, with allow fingers 81a～81d and 82a～82d for example as shown in the figure, be that the dimple of circle and the suitable end surface of shape on circular open and

sliding component

52,53 and 60,61 stretch out vertically by the part in the part 151 of fuse shown in Figure 7.If do not need or do not require the swaged forging effect, then above-mentioned machine can be only with two axial locations, rather than three.Sliding component also can drive with other device, rather than with mechanical cam-operated.But, the various mobile coordination of sliding component and their timing can be finished better by the suitable design and the synchronous operation thereof of cam member, and this synchronous operation is for example driven by sprocket wheel-chain drive by a single motor.
