Background
The tooth punching process is an important ring in the metal card clothing manufacturing process, the tooth punching machine for card clothing processing comprises a tooth punching mechanism and a material pulling mechanism, three to four punching knives, namely upper cutting dies, are fixed on the periphery of a cutter head in the tooth punching mechanism at equal intervals, each upper cutting die comprises a fixed base part and a cutter body part, the top end of the cutter body part is a tooth punching circular arc, and the two sides of the tooth punching circular arc are a tooth punching inclined plane and a tooth punching straight plane. When the upper cutting die runs from top to bottom during tooth punching, the card clothing is pulled forwards at a constant speed by the pulling mechanism. The tooth punching straight surface of an upper cutting die of the existing grinding machine tool is basically ground vertically, and the width of the tooth punching straight surface of the upper cutting die is usually about 0.8cm, so that the upper cutting die with the width cannot instantly leave card clothing when continuously running downwards after tooth punching, and in fact, the tooth punching straight surface of the upper cutting die after tooth punching gradually increases resistance generated by the card clothing which does uniform motion after tooth punching when moving downwards, namely the motion of extruding the card clothing, and the resistance, namely the extrusion force disappears until the upper cutting die is completely separated from the card clothing. The upper cutting die with the vertically polished straight surface of the punching tooth is blocked by the upper cutting die when the card clothing is punched with teeth, namely, the extrusion force is gradually increased to generate the phenomena of straight edge bending deformation or burrs and the like, so that the card clothing is produced to be an unqualified product.
The upper cutting die is easy to wear or damage in the process of processing the card clothing, so the upper cutting die needs to be frequently processed or re-polished during the production of the card clothing, a fixed clamping seat for fixing the upper cutting die and a circular grinding wheel for polishing the upper cutting die are usually arranged on a polishing machine tool, and the upper cutting die fixed by the rotating circular grinding wheel can only be vertically polished from top to bottom. If the circular grinding wheel is inclined at a certain angle, namely the circular grinding wheel is manually rotated to grind the upper cutting die, the straight tooth punching surface of the upper cutting die is inclined at a certain angle to eliminate the defects of straight edge bending or burr and the like generated when the card clothing is used for punching teeth, the upper cutting die is vertically fixed on a fixed clamping seat of a grinding machine tool, only one upper cutting die can be ground each time, the operation not only causes low efficiency, but also is difficult to avoid large errors generated by the inclined angle of the straight tooth punching surface of each upper cutting die in each manual operation.
