CONSTITUTION:It is necessary for a steel plate 1 to be polished that both short and long sides of the steel plate 1 are chamfered, and burrs which are projected from the upper or lower surface of the steel plate 1 at holes formed in both ends of the steel plate 1 are removed. Then, a rectangular transferring path is formed provided with longitudinal paths 3, 4 and transverse paths 5, 6. A short side chamfering device 57 is arranged in opposite to the upstream end of the longitudinal path 4, and a long side chamfering device 90 is disposed downstream of an upper surface polishing machine 57 provided in the intermediate section of the longitudinal path 4. Further, a short side chamfering device 103 is arranged in opposite to the downstream end of the longitudinal path 4, and a reversing device 105 is disposed in the intermediate section of the transverse path. Thus the chamfering and deburring of a steel may be efficiently made.

Description

[Detailed description of the invention] The present invention relates to a steel polishing device.

For example, when manufacturing steel materials for bridges, it is necessary to chamfer the short and long sides to make it convenient for welding the steel materials on site. Also, holes on both ends of the steel material? If a hole is drilled, it is necessary to scrape off the area around the hole. In the past, this work was performed separately, resulting in inefficiency.

Therefore, the present invention provides a steel material polishing device that completely eliminates such problems, and its feature 1 is ζ
A transfer device that forms a rectangular steel material conveyance path with the first and second vertical paths and the first and second horizontal paths, and transfers the steel materials on each path to the downstream path. A short side chamfering device that chamfers the four short sides of the steel material at the end of a suitable route?
A long side chamfering device for chamfering the long sides of the steel material 9 and a top surface polishing device for completely cleaning the top surface of the steel material are installed in the middle of an appropriate route. Conversion @ all steps are completed.

According to this configuration, it is possible to efficiently chamfer the short and long sides of the steel material and deburr the top and bottom surfaces in order, and it is possible to completely clean a large number of steel materials in a short time. It has excellent fertility.

Hereinafter, one embodiment of the present invention will be explained with reference to Example 1. What is shown in Fig. 1 is the steel JFA' to be polished, with both short sides (IA) (IB) and both long sides (1
