Definitions

  • Such operating heads are employed in uid powered (hydraulic and pneumatic, for example) tools which are used for a Wide variety of purposes, such as crimping of electrical connectors, where it is not possible or convenient to .axially remove the work piece fro-rn the tool.
  • the opposed force applying jaws of these operating heads are commonly provided with a pair of removable crimping dies which may be interchanged to accommodate work pieces of varying size. Due to the magnitude and nature of the stresses developed in use, C-shaped or open-side operating heads are generally of massive construction in order to provide the necessary support for the dies and sufficient rigidity to prevent deflection and consequent die misalignment; they are therefore usually extremely heavy.
  • a still further object is to provide the foregoing advantages in a construction which is applicable to both mechanical and hydraulic compression tools.
  • FIGURE l is a cross sectional view of a hydraulic tool compression head incorporating this invention.
  • FIGURE 2 is a partially sectioned top view of the C- head of FIGURE l;
  • FIGURE 3 is a side section View of another embodiment of this invention.
  • the C-head of this invention is provided with means for providing a balancing 'force which is in opposition to the forces ygenerated by the jaws of the head in compressing work piece.
  • a balancing 'force which is in opposition to the forces ygenerated by the jaws of the head in compressing work piece.
  • the balancing forces may be made equal in effect to the forces generated by closing of the compressing jaws and may be varied in proportion to the load, as shown by the construction illustrated in FIGURE l; alternatively, the balancing forces may be selected to obtain ya specific predetermined value suflicient to counterbalance the forces likely to Abe encounteredin a specific application.
  • variable balancing force compression head of FIGURE l may be seen to comprise a lower body portion and an upper opposed body portion 12 which are joined together by one or more axial tension bolts 14. -In the ernlbodiment shown, the upper and lower body portions are spaced apart by a pair of tubular spacers such as 16,
  • Pressure fluid inlet 26 is operatively connected to fluid passages 28 and 30 for applying fluid pressure to the force applying rams within the two bores 18 and 20.
  • Each of the rams 22 and 24 may be provided with a piston ring 32 and 34 respectively to seal the ram to the bore wall.
  • the upper part of ram 22 is provided with :a seat 36 for receiving one half-section 38 of compressing die.
  • the opposed part of upper body portion 12 similarly includes a seat ⁇ 40 for removably receiving a mating die half-section 42.
  • an electrical connection such as 44 (shown in dot dash lines) between the substantially channel-shaped die surfaces 46 and 48, in a well known manner.
  • the die-receiving upper portion of the ram includes a puojection 48 which extends between the spacers 16 on the -bolts 14 as shown in FIGURE 2.
  • the opposed trans-A verse edges ⁇ 50 of the projection 48 form a pair of bearing surfaces (only one being shown in FIGURE 2) which engage the spacers or col-lars 16 in sliding relationship to permit longitudinal movement of the ram . While preventing axial rot-ation.
  • the portion of the head corresponding to the area rbetween the axes of the bolts 14 and the axis of the balancing r-am 24 might be formed ⁇ of a solid mass of material integral with the upper and lower body portions 10 and 12.
  • the neutral axis of such a structure would be substantially to the left of the effective neutral axis 'of this invention, the indio cated mass of material would be in tension to the right of the neutral axis and in compression to the left, and the resultant total reflection of the upper die section relative to the lower die section would correspondingly be substantially greater than in the compression headl of this invention.
  • any elongation of the tension bolts 14 during operation which tends to permit upper body portion 12 to tilt relative thereto as a result of the force applied in compressing the connector, is fully compensated by the corresponding displacement of the body along the axis of the balancing force applying ram.
  • the operating head comprises a lower body portion110 and an upper body portion 112 which are joined together by tension bolt v11d, and spaced apart by a spacing collar 116.
  • Body portion 11G is provided with a cylindrical bore 118 having a compression torce applying ram 122 itted therein; and both the ram and the upper body portion 112 are litted with complementary die halt sections 132 and 134 respectively. Compression forces are transmitted to any connector disposed between the die half sections 132 and 134i by means of fluid pressure applied through ⁇ fluid inlet passage 126, to ram 122 in the Well-known manner described with reference to the ernbodiment of FIGURES l and 2.
  • 'I-'he balancing ram arrangement of the embodiment of FIGURE l uses tubular element merely to space body portions 1t) and 12; in'the present embodiment, body 112 is pro-vided with a balancing force receiving pad 160 which rests upon the surface of a corresponding oiset portion 162 of the lower body portion 110, and the tension bolt 114 is preloaded, by tightening tension bolt nut 150 beyond the force necessary merely to secure the upper and lower body portions together, in order to seat pad 160 securely on portion 162.
  • the initial deflection of the entire head assembly due to preloading of the bolt is then relieved during compressio-n of a connector to thereby limit the maximum total detiection caused by compression.
  • the force applied to the died parts may be developed bymeans others than the uid power mechanisms selected for illustration in the drawings.
  • the force may be derived for example, from electric motors or from manually operated linkages employing well known techniques for obtaining the necessary mechanical advantage and for moving one die section relative to the other.
  • An operating head fora compression tool comt prising: a rst body portion supporting a die section, a second body portion supporting a complementary die section; means tor holding the first body portion to the second body portion; means on one side of said holding means for advancing one die section toward the other die section independently of said body portions; and means for applying ya counterbalancing force, on substantially the opposite side of said holding means, to resist tilting of the two body portions with respect to each other.
  • said holding means includes at least a tension bolt disposed intermediate said advancing means ram and said counterbalancing means ram, and said advancing means ram includes means engaging said bolt for preventing rotation of said advancing ram.
  • said holding means includes a pair of parallel spaced-apart tension bolts disposed intermediate said counterbalancing force applying means and said advancing means, said bolts being disposed in a plane which is substantially perpendicular to the plane defined by the axes of said force applying and advancing means.
  • said counterbalancing force means includes a portion of said rst body portion directly engaging an opposed portion of said second body portion; and, said tension bolt is pretightened to hold said engaging body portions together with a force substantially equal to the maximum force applied by said die section advancing means duringr compression.
