|20150298277||APPARATUS AND METHOD FOR GRINDING COMPRESSION LINE SPRING - Disclosed herein is an apparatus for grinding a compression line spring. The apparatus includes a lower chain conveyor (||10-22-2015|
|20150273565||HOT FORMED COILING MACHINE - 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.||10-01-2015|
|20110119920||TAPERED STABILIZER BAR HAVING CONTINUOUSLY CHANGING CROSS-SECTION AND METHOD FOR MANUFACTURING THE SAME - A method for manufacturing a stabilizer bar for a vehicle includes cutting a stabilizer bar material having a round bar-shaped configuration, heating both end portions of the cut stabilizer bar material to be formed as leg bars of the stabilizer bar, rolling both side surfaces of each of both heated end portions of the stabilizer bar material so that both side surfaces are tapered, rotating the stabilizer bar material about an axis thereof between rollers to taper both remaining non-rolled side surfaces of each of both end portions of the stabilizer bar material to be formed as the leg bars of the stabilizer bar, so that each or both end portions of the stabilizer bar material has an elliptical cross-section, forming eyes on distal ends of the stabilizer bar material, and bending the stabilizer bar material into the shape of the stabilizer bar.||05-26-2011|
|20110053471||APPARATUS FOR STRESS SHOT PEENING OF COIL SPRING - An apparatus for stress shot peening of a coil spring is disclosed. The apparatus of the present invention is constructed such that coil springs, which are compressed and clamped by corresponding spring clamping units (||03-03-2011|
|20100243098||APPARATUS AND METHOD FOR MANUFACTURING BARREL COIL SPRING - An apparatus and method for manufacturing a barrel coil spring make it possible to coil opposite sides of a spring material at the same time so as to considerably reduce manufacturing processing, thereby remarkably reducing the time required to manufacture the coil barrel spring, thus improving productivity.||09-30-2010|
|20100225083||TAPERED STABILIZER BAR HAVING CONTINUOUSLY CHANGING CROSS-SECTION AND METHOD FOR MANUFACTURING THE SAME - A stabilizer bar includes a parallel bar which is secured with respect to a frame via fasteners in each of which a bush is fitted, and leg bars which extend from both ends of the parallel bar with distal ends of the leg bars connected to suspension arms. Each leg bar is tapered from an upper end toward a lower end thereof to continuously decrease a section modulus of the leg bar from the upper end toward the lower end thereof so that the stress generated by a load applied to the lower end of the leg bar is not concentrated on a bent part of the stabilizer bar and is distributed over the entire leg bar so as to prevent the stabilizer bar from being broken at the bent part.||09-09-2010|
