Definitions
- THIS INVENTION relates, broadly, to the crimping of detonators for detonating explosives. More specifically, the invention relates to a device and a method for crimping the mouth of a metal detonator housing around an initiating element such as a shock-tube, fuse or electrical lead protruding into the housing.
- a device for crimping the mouth of a metal detonator housing around an initiating element protruding into the housing through the mouth comprising a pair of opposed jaws, at least one which is movable relative to the other and is reciprocally mounted so that at least one of the jaws is reciprocally movable alternately towards and away from the other jaw to successively bring the jaws tightly into contact with each other and then to space the jaws apart from each other; a plurality of toothed segments arranged side-by-side in series on each jaw, at least some of the segments being moveable and at least some of the segments of each jaw being located in one or more cavities provided therefor in the jaw, each segment having a pair of side faces whereby the segment abuts an adjacent segment when the jaws are tightly in contact with each other so that the segments of the jaws together form a segmented ring, the side faces of each segment converging from a broad radially outer end of the segment towards a toothed radially
- Each jaw may have the same number of segments.
- the number of segments in each jaw may be selected by routine experimentation, bearing in mind difficulties in obtaining a desirably circular toothed passage when the jaws are tightly closed, when there are too few segments, and difficulties associated with expense and complexity of construction, when there are too many segments.
- the number of segments in each jaw may thus be in the range of 2 to 8, more preferably 3 to 5, and conveniently 3.
- each jaw may have an odd number of segments, for example 3,5 or 7, the preferred number again being 3, so that there are, in each jaw, a central segment and one or more additional segments on each side of the central segment.
- At least one segment in each jaw may be fixed and hence immovably connected or integral with the remainder of its associated jaw, with a cavity being provided in the jaw on each side of the fixed segment for receiving one or more movable segments.
- all of the segments may be movable, being in the nature of movable inserts, a single cavity being provided in each jaw for receiving the inserts, in which cavity the inserts are located.
- Each cavity may provide one or more abutment faces for abutting respectively against the broad ends of the movable segments.
- the abutment faces may be flat and the broad ends of the movable segments may have radially outwardly facing surfaces which are also flat.
- Each abutment face and the radially outer surface of the associated segment may be provided with a radial projection which projects into an associated tangential slot, relative to the ring.
- the projection may be a radially outward projection from the outer surface of the broad end of the segment and the tangential slot may be provided in the abutment face of the recess, or in principle vice versa, with the projection projecting radially inwardly from the abutment face of the recess and the tangential slot being provided in the outer surface of the broad end of the segment.
- Each biasing element may be an elastomeric block which is held captive in a cavity provided therefor in the side face of one of the segments of the pair of segments between which it acts.
- the elastomeric block may project tangentially outwardly from its cavity relative to the axis of the ring, when the jaws are spaced apart from each other, the block thereby acting to space apart the segments of the pair, and is compressed and forced into its associated cavity by the side face of the other segment of the pair when the jaws are tightly in contact with each other.
- Each elastomeric block may be cylindrical in shape, being located in a correspondingly part-cylindrical cavity having an axis which is parallel to the axis of the ring.
- the axes of the polygons may be parallel to the axis of the ring, and each cavity may in turn also extend from one major face of the bar to the other.
- Each major face of each bar may be enclosed by a cover plate, which acts to hold the segments and biasing elements in place against axial movement thereof in the direction of the ring axis.
- the device may include a guide pin protruding from at least one of the segments, into a complementary guide slot in the cover plate which abuts that segment.
- each of the segments may be provided with such a guide pin, with each guide pin then located in its own complementary guide slot.
- the jaws may further be provided respectively on their side edge faces which abut when the jaws are tightly in abutment, with a guide pin and an opposed tubular guide socket, the pin entering the socket when the jaws approach each other, and leaving the socket when the spacing between the jaws is increased sufficiently, as the jaws leave each other.
- a succession of detonator housings are moved intermittently in series along a path extending between the jaws, in a direction perpendicular to the axis of the ring, with their associated initiating elements in place, optionally held there by a resiliently flexible sleeve or ferrule located coaxially between the mouth of the detonator housing and the initiating element, the detonator housings being aligned parallel to the ring axis, while the jaws are spaced apart, with each detonator housing being placed between the jaws and coaxially aligned with the ring axis, before the jaws are moved together into tight abutment with each other to clamp the detonator housing mouth between the jaws by means of the segments, the segments moving radially inwardly towards the ring axis to crimp the mouth of the detonator housing around the initiating element.
- the invention accordingly extends to a method of crimping the mouth of a metal detonator housing around an initiating element, the method including the steps of: moving a succession of detonator housing in series intermittently along a path extending between a pair of opposed jaws, the detonator housings being in turn located in a stationary condition between the jaws; and moving the jaws into abutment with each other to grip a mouth of the stationary detonator housing located therebetween by means of toothed segments mounted on the jaws which, when the jaws are tightly in abutment with each other, form a segmented ring defining, at its centre, a passage having a toothed circumferential outline, the segments being arranged simultaneously to move radially inwards towards and into contact with the mouth of the housing located between the jaws as the jaws approach each other, to crimp the housing against the initiating element by the time the jaws are in tight abutment with each other, the detonator housing being coaxially aligned with
- moving the jaws into abutment may be against a bias which acts to space the segments apart from one another and to space the segments radially outwardly, automatically to enlarge the ring, as the jaws move apart.
- a bias which acts to space the segments apart from one another and to space the segments radially outwardly, automatically to enlarge the ring, as the jaws move apart. It is a feature of the invention that it allows the series of detonator housings intermittently to be moved, typically in a straight line, along a path extending between the jaws and perpendicular to the ring axis, while the jaws are reciprocated in synchronisation with the intermittent movement of the detonator housings, between a tightly abutting condition with their segments located around a crimped detonator housing mouth, and a condition spaced apart to allow subsequent movement of the detonators along the path, thereby permitting low crimping cycle times, as short as about 2s or less, for the crimping of each deton
- FIGURE 1 shows a sectional plan view of a device in accordance with a first embodiment of the invention, in a direction parallel to the axis of its ring of segments, with its jaws spaced apart;
- FIGURE 2 shows a view corresponding to Figure 1 , with the jaws tightly in abutment; and FIGURE 3 shows an exploded three-dimensional view from the bottom and side, of a device in accordance with a second embodiment of the invention.
- reference numeral 10 generally designates a device in accordance with a first embodiment of the invention for crimping the mouth of a metal detonator housing (not shown).
- the device 10 comprises, broadly, a pair of opposed elongate-rectangular hardened mild steel jaws 12, 14, having a length of 120 mm, a width of 40 mm and a thickness of 20 mm.
- the jaws thus have 120 x 40 mm 2 major faces, 120 x 20 mm 2 side edge faces designated 16, and 40 x 10 mm 2 end edge faces designated 18.
- the jaws 12, 14 are viewed face-on to their major faces and are shown with their major faces co-planar, one face 16 of the jaw 12 being opposed to one face 16 of the jaw 14, the opposed faces 16 being shown tightly in abutment at 20 in Figure 2, and spaced apart by a spacing "S" in Figure 1 .
- the jaws 12, 14 are reciprocably mounted on a hydraulic reciprocating mechanism (not shown) arranged to reciprocate them simultaneously between a closed condition, shown in Figure 2, and a fully open condition in which they are spaced apart sufficiently to allow a series of detonator housings to be crimped to pass between the jaws in a direction parallel to their edge faces 16.
- the direction of reciprocation is normal to the faces 16 and is shown by arrow 22, and the direction of movement of the detonator housings is shown by arrow 24.
- the jaws 12, 14 are not shown fully spaced apart, but only partly spaced apart, the jaws in their fully spaced-apart condition permitting a succession of detonator housings to pass therebetween in the direction of arrow 24, midway between their opposed side edge faces 16, without being interfered with by the guide pin 26 (described hereunder) provided on the jaw 12.
- the jaws may be movable by a pneumatic reciprocating mechanism or by a mechanical reciprocating mechanism such as a crank; and it will be appreciated that in other examples only one of the jaws 12, 14 need reciprocate, the other being stationary.
- the detonator housings are carried past the jaws 12, 14 by a conveyor mechanism (not shown) situated below the jaws 12, 14, the edge faces 16, 18 being vertical and the major faces being horizontal, with the detonator housings projecting upwardly from the conveyor mechanism to present their mouths at a desired elevation between the opposed side edge faces 16.
- the conveyor mechanism moves a succession of detonator housings intermittently in the direction of arrow 24 when the jaws 12, 14 are sufficiently spaced apart, and holds the detonator housings stationary at other times.
- the pin 26 is held captive in a passage 28 in the jaw 12, by a screw 30 which screws axially into the inner end of the pin 26 and engages with a tapped extension 32 of the passage 28.
- the jaw 14 is in turn provided with a passage 34 which receives the part of the pin 26 which projects from the jaw 12, when the jaws 12, 14 are sufficiently closely spaced from each other, to guide accurate movement of the jaws into face-to-face abutment of their side edge faces 16.
- Each jaw 12, 14 is provided, in its side edge face 16 which faces the other jaw, with a semi-regular-hexagonal indentation 36 (see Figure 1 in particular) which is broadly C-shaped and provides three abutment faces 38, namely a central abutment face and a pair of lateral abutment faces respectively on opposite sides of the central abutment face.
- the faces 38 are flat and are directed radially inwardly towards the axis 40 of the hexagon of which they form part.
- Each of the lateral abutment faces 38 is provided with a slot 42.
- Each slot 42 is located midway between the major faces of the associated jaw 12, 14 and extends in a tangential direction relative to the associated axis 40.
- Each central abutment face is provided with a centrally positioned passage 44 which receives a sleeve 46 as described hereunder (see Figure 2).
- Each hardened mild steel segment 48 is provided in each indentation 36, namely a central segment and a pair of lateral segments on opposite sides of the central segment.
- Each segment 48 when viewed in a direction parallel to the axes 40, is broadly equilateral-triangular in outline, having a broad end 49 which is radially outermost, for abutment against an associated abutment face 38, a pair of side faces 51 for abutment against adjacent segments 48, and a toothed inner narrow end 53, having teeth which extend parallel to the axes 40, the abutment in question taking place when the jaws 12, 14 are in abutment, as shown in Figure 2.
- the broad ends 49 of the lateral segments 48 remain at all times, however, in abutment with the lateral abutment faces 38 having the slots 42.
- Each of the lateral segments 48 has an insert 50 screwed into a tapped socket in the broad end 49 of the segment 48, the insert 50 providing a projection which projects radially outwardly, relative to the associated axis 40, from the broad end of the segment 48, into the associated slot 42 in the associated abutment face 38. Location of this projection in the associated slot 42 holds the lateral segments 48 captive in the associated indentation 36, the lateral segments in turn holding the respective central segments 48 captive in said indentations 36.
- One side face of each segment 48 is provided with a part-cylindrical cavity 52 which holds a cylindrical rubber biassing element in the form of a cylindrical block 54 press-fitted into the cavity 52.
- each sleeve 46 contains a coil spring 56 under compression, each sleeve 46 projecting into a socket 58 provided therefor in the central segment 48 associated with the central abutment face 38 having the passage 44 receiving said sleeve 46.
- Each sleeve 46 thus projects from the socket 58 in the associated central segment 58, into the associated passage 44 in the associated abutment face 38, being a press fit in the socket 58, but being slidable in the passage 44.
- the coil spring 56 acts against segment 48 at the inner end of the socket 58, and against a plug 60 held in an extension of the passage 44 by a grub screw 62.
- the springs 56 are omitted from Figure 2 for ease of illustration.
- Two plastics cover plates are provided to cover the major faces respectively of each jaw 12, 14. Minor projections of the lower cover plate can be seen in Figure 1 at 64.
- the cover plates are bolted to the jaws 12, 14 by bolts 66 provided with washers 68, the positions of the bolts 66 and washers 68 being illustrated schematically.
- the cover plates act to enclose the segments 48 to prevent unwanted movement of the rubber blocks 54 and the segments 48 in the direction of axes 40, while protecting against the ingress of dirt.
- each central segment 48 abuts its associated abutment face 38, the side faces 51 of adjacent pairs of the segments 48 all being in abutment and the rubber blocks 54 all being under lateral compression and forced laterally into their respective cavities 52.
- the axes 40 will coincide and the segments 48 will form a segmented ring around a central axis, also designated 40 in Figure 2, provided by the coinciding axes 40 of Figure 1 .
- the conveyor mechanism when the jaws 12, 14 are sufficiently spaced apart, successively and intermittently moves the detonator housings into position, in the direction of arrow 24, to place them at the position of the central axis 40 shown in Figure 2, with the projections of the inserts 50 being located at the ends of their respective slots 42 which are closest to the opposed edge faces 16 of the jaws 12, 14, and with the rubber blocks 54 spacing the side faces of the segments 48 apart.
- the springs 56 are compressed to bring the broad ends of the central segments 48 into abutment with their associated abutment faces 38; and the lateral segments 48 slide along their respective abutment faces 38 until the projections of their inserts 50 are at the ends of their associated slots 42 furthest from the opposed faces 16 of the jaws 12, 14, at which stage the situation shown in Figure 2 is reached, with the opposed faces 16 in abutment.
- the toothed radially inner narrow ends of the segments 48 converge axially inwardly towards the axis 40 and towards one another, until they form the substantially circular central passage shown around the central axis 40 in Figure 2.
- said toothed radially inner ends act to crimp the mouth of the housing around the initiating element (and any sleeve or ferrule holding the initiating element) projecting in the housing.
- the rubber blocks 54 act automatically to space the side faces of the segments 48 apart in each jaw 12, 14, while the springs 56 automatically move the central segments 48 away from their respective abutment faces 38, the projections of the inserts 50 of the lateral segments 48 moving back to the ends of the associated slots 42 closest to the opposed faces 16 of the jaws 12, 14, the outer ends of the lateral segments 48 sliding along their respective abutment faces 38.
- reference numeral 100 generally designates a device in accordance with a second embodiment of the invention, for crimping the mouth of a metal detonator housing (not shown).
- the pin 26 in the jaw 12 and the complementary passage 34 in the jaw 14, have been dispensed with.
- the device 100 includes upper cover plates 102, 104 and lower cover plates 106, 108.
- Bolts 66 protrude inwardly from the lower cover plates 104, 108, through passages 1 10 in the jaws 12, 14, and engage threaded sleeves 1 12 protruding inwardly from the upper cover plates 102, 104.
- the device 100 also includes a guide pin 1 14 protruding from each of the segments 48, with each guide pin nestling or located movingly in a guide slot 1 16 provided in one of the lower cover plates 106, 108.
- the guide pins 1 14 and guide slots 1 16 ensure accurate and consistent movement of the segments 48.
- the detonators are described as moving in the direction of arrow 24, in other examples they can move in a direction perpendicular or normal to the direction of arrow 24, and parallel to the direction of arrow 22.
- the jaws 12, 14 will not only be reciprocated towards and away from each other in the direction of arrow 22, but will also be indexed simultaneously in a direction parallel to the direction of arrow 24 into crimping stations in which they can reciprocate towards and away from each other, and out of said crimping stations in a direction parallel to the direction of arrow 24, to allow subsequent movement of the series of detonators, in a direction parallel to the direction of arrow 22.
