Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and 2, the present invention includes a corrugated steel plate 1, an upper roll shaft 2, a lower roll shaft 3, a hobbing 4, a tooth top 5, a tooth valley 6, a punch 7, a hole groove 8 and a connecting hole 9. As shown in fig. 1, two roll shafts, an upper roll shaft 2 and a lower roll shaft 3, are provided in a direction perpendicular to the traveling direction of the corrugated steel sheet 1. The two roll shafts are driven to rotate (not shown in the figure) through power mechanisms such as a motor, a gear and the like, the rotating directions are opposite, the upper roll shaft 2 and the lower roll shaft 3 are arranged up and down along the corrugated steel plate 1, the axes of the two roll shafts are parallel, and the formed plane is perpendicular to the plane of the corrugated steel plate 1. The rotating directions of the two roll shafts are opposite, and a circle of hobbing 4 is uniformly arranged around each roll shaft and comprises a tooth top 5 and a tooth valley 6. The tooth tops 5 and the tooth valleys 6 are uniformly distributed along the circumferential direction of the roll shaft, and the intervals are equal. The tooth tops 5 and the tooth valleys 6 are both arc-shaped, and the axial line of the arc is parallel to the axial line of the roll shaft and is equal to the axial line of the roll shaft in distance. The circular arc shapes of the tooth crests 5 and the tooth troughs 6 are the same as those of the wave crests and the wave troughs of the corrugated steel sheet 1. The roll shaft and the hobbing are made of steel materials.

As shown in fig. 2, punches 7 or hole grooves 8 for punching are provided on the tooth crests 5 and the tooth valleys 6 of the upper roll shaft 2 and the lower roll shaft 3, respectively, and the punches 7 and the hole grooves 8 on the upper roll shaft 2 or the lower roll shaft 3 are distributed at intervals on the tooth crests 5 and the tooth valleys 6, and the punches located on the upper roll shaft and the lower roll shaft correspond to the hole grooves. For example, the punch on the tooth crest of the upper roll shaft 2 corresponds to the hole groove on the tooth valley of the lower roll shaft 3, and the hole groove on the tooth valley of the upper roll shaft 2 corresponds to the punch on the tooth crest of the lower roll shaft 3. The width of the slot 8 is greater than the width of the punch 7. After the corrugated steel plate 1 enters the hobbing between the upper roller shaft 2 and the lower roller shaft 3, the upper hobbing and the lower hobbing with the punch 7 and the hole groove 8 gradually rotate to press, the punch 7 punches a hole to complete punching, the connecting hole 9 is punched on the corrugated steel plate 1, the punched hole piece falls into the hole groove 8, the punching is completed, after the corrugated steel plate 1 is rotationally transferred out of the upper roller shaft and the lower roller shaft through the roller shafts, the forming of the connecting hole 9 is completed, and the hole piece in the hole groove 8 falls out along with the rotation of the roller shafts.

When the corrugated steel plate enters the hobbing teeth of the upper and lower roll shafts, the upper and lower hobbing teeth with the punch and the hole groove rotate gradually to be pressed, the punch finishes punching, punched hole pieces fall into the hole groove, and punching is finished.
