Patent number: 9744584Abstract: The present invention relates to a hot coiling machine, and an object of the invention is to provide a hot coiling machine that produces coil springs having various coil shapes and diameters from a heated wire without a mandrel. The present invention provides a hot coiling machine including: a center roll rotating by a drive unit; a feeding roll disposed near the center roll and facing an external surface of the center roll, the center roll being configured to move by a first positioning unit and being rotated by a drive unit thus moving a wire together with the center roll; a forming roll for forming the wire into a coil shape; and a pitch control unit disposed near the forming roll to come into contact with the coiled wire and pushing the coiled wire to provide the coiled wire with a desired pitch.Type: GrantFiled: March 27, 2014Date of Patent: August 29, 2017Assignee: DAE WON KANG UP CO., LTD.Inventors: Chan-Gi Jung, Ui-Seuk Yoon

Patent number: 9718162Abstract: Disclosed herein is an apparatus for grinding a compression line spring. The apparatus includes a lower chain conveyor (100), an upper chain conveyor (200), and grinding units (300). The lower chain conveyor includes chain units each having first support blocks (115) for supporting compression line springs. The upper chain conveyor includes chain units each having second support blocks (215) for compressing downward upper portions of the compression line springs and thus supporting the compression line springs. The grinding units grind seat surfaces formed on opposite ends of the compression line springs that are moved by the upper and lower chain conveyors. A V-shaped depression (115a) is formed in each first support block so that each of the compression line springs is seated onto the corresponding V-shaped depression. A lower surface (215a) of the second support block that compresses the compression line springs has a planar structure.Type: GrantFiled: April 17, 2013Date of Patent: August 1, 2017Assignee: DAE WON KANG UP CO., LTD.Inventors: Chan-Gi Jung, Ui-Seuk Yoon
