[0001] IMPROVED ROLLING APPARATUS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rolling apparatus, and more particularly, to a rolling apparatus that automates the entire process of transferring a material such as a screw or a bolt to a roller,

Generally, machining of parts such as bolts, screws, rings, screws, gears, spline shafts and the like is performed by a rolling process in which the surface shape of the tool is stamped on the material by rotating the cooling material or the roll or both.

Such a roiling process has a large strength of the product because the fibers of the material produced by rolling or extrusion are not cut as compared with the cutting process. Since the material and the tool are locally contacted, the process can be performed with a relatively small processing force. since the chip is not produced, the utilization rate of the material is high, the product is hardened by the plastic deformation, and the structure is dense and the mechanical strength is large, which is widely used for part processing.

As an example of such a rowing machine, a Korean Registered Utility Model No. 20-0321586 (registered on Jul. 16, 2003) discloses that a thread rolling die is provided with an invitation ball and a fixing bolt on a support table on which an inclination angle is adjusted through an invitation ball and a fixing bolt A pair of front and rear receiving plates arranged to be able to adjust the spacing width and both front and rear receiving plates are connected to the rear receiving plate and the support table There is disclosed a material automatic feeding device for a rotary launderer in which a workpiece receiving portion including a support rod for being connected and supported to a fixed bracket is provided.

When the cam 15 rotates, the cam protrusion 15b pushes the operation roller 13, and the right side of the operation space 10 rotates downward so that the left side of the operation space 10 rotates upward in the drawing The stopper bar 16 is moved forward by the elasticity of the spring (not shown) to block the material 17 while the stopper bar 16 rotates upward, An automatic material supply apparatus of a machine is disclosed.
In the drawings, reference numeral 3 denotes a rotary shaft, 4 denotes a rouler, 6 denotes a conveying passage, 7 denotes a discharge passage, and A1 to A3 denote introduction, processing and discharge paths of the material.

However, since materials such as bolts, which have been subjected to primary rolling in the above-described conventional technology, may be injured by burrs generated during the thread forming process, burrs generated during thread formation are removed to prevent worker injury, There is a need for a post-treatment to remove coagulated excess rust-preventive corrosion-resistant paint deposits on the surface of the material due to deposit in the rust-preventive corrosion-resistant paint. Conventionally, as described above, the post-processing for removing burrs of the same material as the bolts and the surplus rustproof corrosion-resistant paint residues on the surface is performed manually, but the work efficiency is very low, And to develop a technology to automate the re-routing process.
