Definitions

  • the present invention relates directly to an improvement of a connecting apparatus for the driving shaft of a cold-roll forming machine. More particularly, the present invention relates to a connecting apparatus for a driving shaft in a cold-roll machine in which a coupling being connected by means of a driving unit and an expandable type universal joint is attached to a coupling holder which is attached to a linear guide which is able to slide in a vertical direction in such a manner that said coupling can move fine-adjustably in both horizontal and vertical directions. Moreover, in the presently invented connecting apparatus, the coupling holder is pushed downward while sliding an intermediate stand which is supporting aforementioned coupling and coupling holder on a common base to locate the coupling at an opposing position against a roll shaft end portion.
  • a connection of holder with said roll shaft can be completed through one operational procedure.
  • said coupling can be free along the vertical direction, so that the present invention can provide a mechanism to freely conduct a fine-adjustment of the pushing-down force during the roll-forming operation, regardless of a distance between upper and lower roll shafts.
  • a cold-roll forming machine (hereinafter, which is merely referred as to a roll forming machine) has been widely employed for various types of industrial and structural metallic components to form into numerously different shapes.
  • a roll forming system which consists of various forming roll stands (hereinafter, which are merely referred as to a roll stand)
  • an attached facility for supplying raw metallic materials to be formed is equipped at an upper stream side of the forming line and subsequent processing equipment for drilling, cutting as well as bending procedures are arranged and connected sequentially at a down stream of the forming line.
  • a cassette-type cold-roll forming machine has been developed and utilized.
  • a plurality of roll stands are mounted on a sub-base which is structured on a common base in an attachable/detachable manner.
  • the forming rolls can be exchanged and said adjustments can be conducted, in advance, in an off-line manner. Therefore, after exchanging the sub-base, said cold-roll forming machine can be operated by simply connecting said sub-base to a driving unit which is provided at the common base.
  • an energy-saving type roll-forming machine has been proposed and developed.
  • said roll forming machines a plurality of the aforementioned sub-bases are prepared, and an exclusive forming roll reserved for a specified shape of raw materials to be formed is equipped for the respective shape, so that a certain type of sub-base can be exchanged according to the targeted final shapes.
  • a mechanism has been proposed by which the sub-base can be connected to the roll shafts by one operational procedure by a sliding movement of the sub-base on the common base.
  • This mechanism can be achieved by providing an intermediate stand on the common base side to support the coupling which is provided at the distal end portion of the universal joint.
  • the aforementioned mechanism when particularly, the distance between the upper and lower shafts is altered during exchanging the forming rolls, a satisfactory connection is not able to be achieved by one operational procedure if the coupling position of the intermediate stand is not accurately adjusted according to the above-mentioned exchanging procedures.
  • the number of the roll stands being mounted on the sub-base becomes larger, it would be extremely difficult to accomplish a connection procedure by just one operational procedure.
  • the coupling center should properly correspond to any degree of changes in height in the roll shafts.
  • the roll forming system in such a way that either (i) said system possesses a degree of freedom with respect to the height position, or (ii) said system can conduct simultaneously the necessary position change in corresponding to the adjustment of the pushing-down force of the roll stands.
  • the coupling being connected by a driving unit and an expandable type universal joint is attached in a fine-adjustable manner to a coupling holder in both horizontal and vertical directions; said coupling holder is provided at a linear guide which is slidable in the vertical direction.
  • said mechanism while the intermediate stand connecting the coupling and coupling holder slides over a common base, the coupling holder which was previously pulled upward is descending until it stops at a guide for the automatic center-positioning to oppose said coupling against the roll end portion.
  • a perfect connection with the roll shaft can be achieved by one operational procedure while adjusting the height automatically without a read-out and control procedures of the coupling height.
  • said coupling procedure is completely free along the vertical direction, and an adjustment for the pushing-down force can be accomplished freely during the forming operation regardless of the distance between the upper and lower roll shafts.
  • the present invention provides a connecting apparatus for a cold-roll forming machine which connects a driving unit being connected at the common base side and a roll shaft of roll stands; said connecting apparatus is furthermore characterized by (i) providing an intermediate stand - which supports a coupling being attached at the other end portion of an expandable type universal joint to connect the driving unit - on a common base in a slidable manner along the roll shaft direction, (ii) loosely-supporting a coupling in a slidable manner in both horizontal and vertical directions at the coupling holder; a spline groove is formed in said coupling along an axial direction on the inner peripheral surface, and a guide being formed by said spline groove at an inlet portion of the coupling is mounted in an attachable/detachable manner at said coupling, (iii) attaching a linear guide, which can slide the coupling holder in a vertical direction, to make it possible to move up and down through a cylinder apparatus, (iv) positioning a guide bar

  • Fig. 2 is a figure to explain the intermediate stand of the connecting apparatus for the cold-roll forming machine of the present invention when looking from a roll shaft direction.
  • Fig. 3 is a figure to explain an engaging condition between the coupling and roll shaft.
  • Fig. 4 is a figure to explain a relationship between heights of the upper and lower roll shaft centers and heights of the upper and lower coupling centers in the connecting apparatus for the cold-roll forming machine according to the present invention.
