Description

  The present invention relates to a processing deburring device, and more particularly to a processing deburring device that removes processing deburring from a plate-like workpiece.

  When a plate material such as an aluminum alloy plate is cut or punched, a processing burr is generated on the cut surface. For example, as schematically shown in FIG. 13, when a plate material such as an aluminum alloy plate is cut with a rotary blade of a cutting machine, a so-called end mill, the edge Wa of the cut surface Wc of the cut workpiece W and the back surface Wa side or the back surface A processing burr We projecting to the Wb side is generated. Further, when drilling is performed with a drill or the like, a processing burr We drilled so-called hole burr that is drilled and protrudes from the edge of the hole Wd to the front surface Wa side or the back surface Wb side is generated.

  The processing burr We projectingly formed on the cutting surface Wc of the workpiece W or the edge of the hole Wd causes the quality of the workpiece W to deteriorate, and thus is removed by various methods.

  For example, as shown in FIG. 14, the processing deburring device disclosed in Patent Document 1 has an upper surface on which a polishing belt 113 is wound endlessly by rollers 114a, 114b, and 114c above a workpiece conveyor 111. Grinding devices 112 are arranged to face each other. A lower surface grinding device 115 and a work carry-out belt conveyor 119 in which a polishing belt 116 is wound endlessly around rollers 117a, 117b, and 117c are arranged in order on the downstream side in the conveyance direction of the workpiece conveyor 111. A workpiece holding belt conveyor 118 is disposed above the grinding device 115.

  Then, the workpiece W is conveyed by the workpiece conveyor belt conveyor 111, and the upper surface, for example, the surface Wa is polished by the polishing belt 113 of the upper surface grinding device 112 to remove the processing burr protruding to the surface Wa side. Further, the back surface Wb is polished by the polishing belt 116 of the lower surface grinding device 115 while being conveyed by the work holding belt conveyor 118, and the processing burr protruding to the back surface Wb side is removed. The processed product W from which the processing burrs have been removed is carried out by the workpiece conveyor belt conveyor 119.

To do. Thereby, the processing burr | flash which protrudes to the surface Wa side of the moving workpiece | work W is rubbed by the buffalo 72, and can be efficiently divided and removed from the workpiece | work W.

  On the other hand, the machining burrs separated from the workpiece W by the buffalos 46 and 72 are dropped downward to suppress adhesion to the workpiece W, and the machining burrs and dust adhering to the buffaloes 46 and 72 are removed by the cleaning liquid supply device 2. It is removed by the cleaning liquid to be sprayed, and clogging of the bafloras 46 and 72 can be prevented or suppressed. Further, it is possible to prevent or suppress the problem of damaging the workpiece W by the processing burr attached to the buffaloa 46 and 72.

  The workpiece W from which the processing burrs protruding toward the front surface Wa and the rear surface Wb are removed by the first polishing mechanism 21 and the second polishing mechanism 50 is the downstream conveyor belt 37 of the downstream conveyor belt conveyor 31 and the downstream conveyor. It is sandwiched between the conveyor belt 68 on the downstream side of the belt conveyor 62, transported along the work transport path L, and transported from the work transport outlet that opens to the safety cover 80 and collected. Thereafter, by sequentially loading the workpiece W from the workpiece unloading port 81, the processing burrs protruding from the front surface Wa and the back surface Wb of the workpiece W are removed, and the workpiece W from which the processing burrs have been removed is unloaded from the workpiece unloading port. Collected.

  Therefore, according to the present embodiment, the processing burrs protruding from the front surface Wa and the rear surface Wb of the workpiece W are continuously generated by a simple operation of loading the plate-shaped workpiece W from the workpiece loading port 81 opened to the safety cover 80. As a result, the work of the operator is simplified, the work load is greatly reduced, and the work deburring work efficiency of the work W is improved.
