Field of the Invention The present invention relates to a polishing machine for a metal round bar and a metal round bar capable of continuously processing a round bar into a high quality round bar. The present invention relates to a linear straightening polishing fixed-length cutting device. 2. Description of the Related Art Conventionally, a straight-line straightening polishing fixed-length cutting device (generally referred to as a continuous drawing machine) for a metal round bar material capable of continuously processing a round bar steel into, for example, a reel Pull out the rolled continuous round bar steel (coil material) and pass it through a shot blasting machine to remove the scale adhering to the round bar material, then straighten it in a straight line with a pair of bender and push pointer (preliminary straightening), Then, draw it straight through a die and reduce it to the required outer diameter, and then pass it through several rollers that press against the upper and lower surfaces of the round steel bar and the left and right side surfaces alternately. The round bar steel is cut into a predetermined length by the shear method by a measuring machine or a tip arrival command by a standard length cutting machine, and then the fixed length cut round bar steel is subjected to a straightening and straightening grinding machine and spiraled by a pair of front and rear polishing disks. It is configured such that it is polished while being fed, and is straightened by an intermediate straightening section to further increase the straightness of the straight line. As described above, the conventional straight-line straightening / polishing apparatus for straight round bar made of metal is provided with the straight-line straightening / polishing machine on the downstream side of the standard length cutting machine. In the conventional straightening and straightening machine, a pair of rotatively driven polishing disks made of die steel or cemented carbide are opposed to each other, and polishing sections are arranged on the upstream side and the downstream side, and are rotated in the middle. A straightening section with free nozzles is arranged.Each polishing section is configured such that the center of each pair of polishing disks is offset to the upper side and the lower side with respect to the round steel bar that is cut and transferred from a pair of polishing disks. It is intended to grind a round steel bar, which has been cut at a fixed length, transferred between the upper part of one disc and the lower part of the other disc by pressing it and rotating it spirally, and the straightening part is rotated by the polishing disc.

(3rd Edition Iron and Steel Handbook VI Secondary Processing / Surface Treatment / Heat Treatment / Welding) on pages 26 and 27 for the outline of continuous drawing machine. Attached as reference material. [0005] [Problems to be solved by the invention] However, the conventional straight-line straightening / polishing device and straight-line straightening / polishing machine for round rods made of metal have the following drawbacks. It is possible to install a fixed-length cutting machine on the upstream side and to cut the fixed-length round bar steel to a straight-line straightening and grinding machine provided on the downstream side, and it is not possible to apply continuous round bar steel to the straight-line straightening and grinding machine. Since the round bar steel that has been cut to a fixed length is passed through a straightening / polishing machine, it is not possible to make a round bar steel with a diameter of about 4 mmφ or less that causes a large deviation phenomenon due to contact entry to a polishing disc or a straightening / straightening nozzle. . Since round bars that have been cut at regular lengths are passed between polishing discs and to the straightening nozzle, increasing the transport speed of the round bars causes a large shock when the leading and trailing ends of the round bars pass through the polishing discs and straightening nozzle. Occurs. Particularly, if the straightness is not made high quality by the preliminary straightening and the straightening performed as the pre-process of the straightening and polishing, a greater shock will occur when passing through the polishing disk and the straightening nozzle. Since a round bar steel that has been cut to a fixed length is passed between the polishing discs and the straightening nozzle, a large shock occurs when the front and rear ends of the round steel bar pass through the polishing disc or the straightening nozzle, which causes The life of the straightening nozzle as a consumable item is extremely short. Since a round bar steel that has been cut to a fixed length is passed between polishing discs and a straightening nozzle, a large shock occurs when the front and rear ends of the round bar pass through the polishing disc and the straightening nozzle,
As a result, it is necessary to constantly check whether scratches are left between the polishing discs or the straightening nozzles. Are all defective. A pair of rotating discs that are driven to rotate are cut into fixed lengths to grind while transporting the round bar steel that is pinched and spirally rotated.If the number of revolutions of the polishing disc is too high, the spiral bar speed will be too fast. As a result, scratches are caused between the polishing discs and the straightening nozzle, so that the number of rotations of the polishing disc cannot be increased, and therefore the polishing ability cannot be improved. Since the round steel bar that has been cut to a fixed length is passed between the polishing discs and the straightening nozzle, the front and rear ends of the round steel bar are subjected to stronger straightening than those other than the front and rear ends. 4/100 to 5/100 mm tends to be finely finished, which is one of the causes of quality deterioration, and this tendency becomes more remarkable as the diameter increases. Since the round bar steel that has been cut to a fixed length is passed through, the guide is large and the equipment line is long and large. The present invention has been devised in view of the above-mentioned points, and by making it possible to continuously straighten and straighten a continuous round bar steel, a metal round bar material capable of eliminating various conventional defects. An object of the present invention is to provide a polishing machine and a straight-line straightening polishing fixed-length cutting device for a metal round bar.

Is a continuous linear metal round bar W, which is respectively transferred in the longitudinal direction, is made into a spiral shape by rotating the spinner 1 with a plurality of nozzles 1a, 1a ,. Alternate to bend to gradually reduce the degree of bending and straighten it. The first polishing machine H and the second polishing machine J are composed of two pairs of polishing disks 8a, 8b, 8 which rotate about a planet and rotate about their own axis.
The continuous linear metal round bar W transported in the longitudinal direction by c and 8d is continuously polished. More specifically, the first polishing machine H and the second polishing machine J are respectively
Two pairs of polishing disks 8a, 8b inside the hollow rotating body 3
A metal round bar W, which is continuous in a straight line with a circular cross section and has a wider space between 8c and 8d, is inserted into the round bar material insertion guide 2 on the upstream side, and is inserted into the hollow rotating body 3 from the hollow shaft portion to the downstream side. The pair of polishing discs 8 are inserted through the round bar insertion guides 1 and 1.
After the metal round bar W is clamped by narrowing the intervals of a, 8b, 8c and 8d to adjust the clamping pressure of the two pairs of polishing disks 8a, 8b, 8c and 8d, the hollow rotary body 3 is rotationally driven. If the hollow rotary body 3 is driven to rotate in synchronization with the longitudinal transport of the metal round bar W, the two pairs of polishing disks 8 are driven.
a, 8b, 8c and 8d are planetarily rotated around the metal round bar W integrally with the hollow rotating body 3, and the continuous metal round bar W is transferred in the longitudinal direction so as not to rotate. From the above, the transfer force of the metal round bar W has two pairs of polishing disks 8
a, 8b, 8c, 8d, each pair of polishing disks 8a and 8b and 8c and 8d are given a planetary rotation opposite to each other, and two pairs of polishing disks 8a, 8b, 8c, 8d are provided.
d is continuous because the rotation of the planetary rotation is added to the rotation of the metal round bar W so that the polishing directions of the metal round bar W are opposite to each other and the continuous metal round bar W is transferred in the longitudinal direction. The metal round bar W can be continuously polished in the longitudinal direction. Next, a polishing machine for a metal round bar according to a second embodiment of the first invention of the present application shown in FIG. 2 will be described. The polishing machines H and J for round bars made of metal are made of resin, such as urethane rubber, which can slidably insert round bars W made of metal having a circular cross section, which are transported in the longitudinal direction. A hollow rotating body 3 is provided between the brackets 25, 25 for inserting and supporting the hollow rotating body 2, 2 and has a cantilever shaft 3a supported by a bearing 24. Two pairs of polishing discs, which are pivotally attached to the hollow rotating body 3 and have one disc upper portion and the other disc lower portion, sandwich and press the metal round bar W in the hollow portion 3b whose one end is open. 8a, 8
b, 8c, 8d. As described above, the metal round bar polishing machine and the straight-line straightening / polishing cutting device for metal round rods according to the present invention have the following excellent effects. Have. Since the polishing disk rotates around the metal round bar while rotating around the planet to polish the metal round bar, the metal round bar can be polished without cutting to a fixed length. It is fundamentally different from a continuous drawing machine using a straightening machine or a straightening and polishing machine. That is, it became possible for the first time to straighten a continuous metal round bar material, polish it, and finally cut it to a fixed length. Since it is possible to straighten a continuous metal round bar material, polish it, and finally cut it to a fixed length,
Polishing discs and straightening pieces will be handled as continuous metal rods instead of regular metal rods with both ends.
Even for round metal rods with a diameter of approximately 4 mmφ or less, the uneven phenomenon that occurs at both ends of the round metal rod when it comes into contact with a polishing disc or straightening piece is eliminated, and a metal rod with a diameter of approximately 4 mmφ or less can be used. It became possible to polish for the first time. Since it becomes possible to straighten and straighten a continuous metal round bar material and finally cut it to a fixed length,
Even if the transfer speed is increased, the processing capacity can be improved without causing a shock as in the conventional case when the front end and the rear end of the round steel bar pass through the polishing disk or the straightening nozzle. Since it is possible to straighten and straighten a continuous metal round bar material and finally cut it to a fixed length,
Even if the transfer speed is increased, there is no shock as before when the front and rear ends of the round steel bar pass through the polishing disc or straightening nozzle, so the life of the polishing disc or straightening nozzle as a consumable item is increased. It is possible to extend the operation period of the machine and to extend the regular inspection period. Since it becomes possible to straighten and straighten a continuous metal round bar material and finally cut it to a fixed length,
Since the front and rear ends of the metal round bar never pass through the polishing disc or straightening piece, the polishing disc or straightening piece will be scratched at the front and back ends of the metal round bar. This is completely solved, and the number of defective metal round bar standard length products due to scratches on the polishing disc and the straightening piece is drastically reduced. Conventionally, the transfer speed of the metal round bar material was dependent on the number of revolutions of the polishing disk, that is, the metal round bar material was spirally transferred by the rotational force of the polishing disk. The transfer speed of the metal round bar and the rotation speed of the polishing disk can be adjusted separately, and the rotation speed of the polishing disk can be made higher than the transfer speed of the metal round bar, and Since it is eliminated that the round bar material scratches between the polishing disks and the correction piece, the number of times of polishing can be greatly improved, and the polishing accuracy is improved, so that the added value of the product can be increased. Conventionally, a round bar steel, which has been cut to a fixed length, is passed between polishing discs and a straightening nozzle, so that the front and rear ends of the round bar steel are subjected to stronger straightening than those other than the front and rear ends. 4/100 to 5/1 at the front and rear ends of
Although it tended to be thinned by 00 mm, which was a cause of deterioration in quality, it became possible to straighten a continuous metal round bar, then polish it, and finally cut it to a fixed length. Will handle continuous metal round bar material instead of regular length metal round bar material with both ends, straightening and polishing will be performed uniformly, and straightness will be improved. Since the diameter becomes uniform at both ends of the steel bar and in the middle thereof, and the polishing accuracy is improved, the added value of the product can be increased.
