  • Patent number: 8573014
    Abstract: A quill supporting member supporting a quill may include a movable body, e.g. Z-axis movable body that moves in a Z-axis direction of an XYZ orthogonal coordinate system representing a shaft core of the quill as an Z-axis. A tool holder supporting member supporting a tool holder for holding a tool may include the other movable bodies, e.g. an X-axis movable body that moves in an X-axis direction and a Y-axis movable body that moves in a Y-axis direction. Therefore, the quill is shortened in the Z-axis direction, and a contact area is reduced between a guide path of the quill and a wire rod.

    Abstract: A chuck and arbor apparatus for a spring coiling machine implements an accurate alignment of the block wire guide with the feed line guides from the wire supply rolls. The chuck is modified to provide for discrete, axial clamping positions which correspond to selected wire alignment positions. The arbor is preferably D-shaped to establish a repeatable angular orientation in the chuck, and avoid the need to clamp the arbor while clamping the chuck.

  • Patent number: 5127247
    Abstract: A coiling device for spring coiling machines, having exchangeable elements that contain adjusting screws. Each coiling pin is mounted in a receptacle so as to rotate therewith and so as to be able to rotate therein about its longitudinal axis after a clamping screw is loosened, and to be capable of moving in its longitudinal direction by means of a set screw, and whereby each coiling pin receptacle is mounted in or on a coiling pin holder, by means of which the coiling pin held in the receptacle can be pivoted in a controlled manner by means of set screws, and can be changed in position by means of an adjusting slide that mounts the coiling pin holder, by means of at least one set screw. One or two such coiling devices are preset in one finger or two finger spring coiling machines to produce helical springs from endless wire. An adjusting device is also provided for coiling tools on spring coiling machines having a coiling device.

  • Patent number: 5105641
    Abstract: This invention relates to an apparatus for the forming of wire, namely a leg or spiral spring winding and bending machine.It is an object of the present invention to reduce the expenditure for the production of the apparatus and to universalize the forming operations which can be carried out with each tool.The apparatus including a plurality of tools (86, 88, 90, 92 or 142; 162, 190, 192) on a tool holder (74; 160) which is fixed at the free end of a longitudinally displaceable shaft (12) resembling the known winding spindle and is replaceable. Every existing tool can be brought into the pathway of the wire and hence into operation by positioning the shaft by rotation and longitudinal displacement by means of a drive which is known from the conventional winding spindle but differently controlled.The advantage of this apparatus is that it is of simplified construction and enables the same tools to be used for producing different forms of springs.

  • Patent number: 4312387
    Abstract: A starter motor field winding comprises an uninterruptedly continuous conductor edge wound to encircle a plurality of core elements. The core elements are on a mandrel to which the leading end of a length of strapping is secured. The mandrel is rotated about a first axis to locate successive core elements in position to have coils wound therearound and rotated about a second axis to edge wind the strapping into coils about the core elements.

  • Patent number: 4030327
    Abstract: A spring coiling machine with an improved drive means has a pair of feed rolls for advancing wire from a source of supply to a coiling station. Coiling tools at the station obstruct feed movement and form coil springs and a cut-off tool successively severs the springs. The coiling tools and cut-off tool are operated from a camshaft driven by a first electric motor and a second electric motor drives the feed rolls. Continuous rotation for both camshaft and feed rolls is provided by the electric motors and a mechanism operated by the camshaft lifts an upper feed roll to terminate feed roll gripping action on the wire and to thus terminate wire feed at the completion of each spring. The first or camshaft motor serves as a lead motor and the feed roll motor as a follower. A digital feedback from the first motor is introduced to the control system therefor and also as an input to a second control system for the feed roll motor.

  • Patent number: 4022640
    Abstract: A method of cold-working and stress-relieving iron-chromium ferritic stainless steels of non-heat hardenable type in the AISI 400 series, thereby increasing the ultimate tensile strength while maintaining good tensile ductility. Cold-working is effected by peripherally contacting the steel, i.e., extruding and/or die drawing, to produce a "cellular structure" not attainable in cold rolling. Repetitive cold-working and stress-relief anneals between about 750.degree. and 1200.degree. F increase the ultimate tensile strength in increments and restore the tensile ductility substantially to that of the hot rolled and annealed material, while maintaining the tensile to yield ratio substantially constant. Ultimate tensile strength up to about 400 ksi in small diameter wire is attainable.

  • Patent number: 3988915
    Abstract: A method and apparatus for producing prestressed coil springs whereby the wire is fed about a rotating spindle and taken up or drawn in with a predetermined spacing from the front end of the coils and guided to a point ahead of the front end of the coils in the form of an expanded helix. A stop block is movable along the spindle, fixed against rotation and provided with a plurality of wire grooves at different angles of inclination so that the wire passes beneath the already formed coil as it passes through one of the grooves to produce the desired stress.

  • Patent number: 3934445
    Abstract: A dual purpose spring coiling machine adapted for two point and single point coiling and particularly adapted for convenient and rapid convertibility from one form of coiling to the other. The machine comprises a coiling tool slide assembly mounted on a frame generally opposite a wire feed and guide means and adjacent a coiling station. The tool slide assembly comprises a coiling tool slide and a guide mountable selectively on the frame in three discrete positions. Right and left-hand two point coiling positions respectively employ mounting of the guide in first and second positions inclined upwardly and downwardly 221/2.degree. from the horizontal. Single point coiling is achieved with the guide mounted horizontally. Coiling tool holders mounted on the slide may be selectively moved from one position to another for right and left-hand coiling with a first holder mounted on and movable with the slide.
