Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 2, the punching apparatus for the curved corrugated plate includes: arc support 1, puncher 2, closing device 3, supporting beam 4. The arc support includes an arc surface and a base rail. The arc surface of arc support 1 is used for placing the arc buckled plate, and the buckled plate ripple direction is the same with arc surface extending direction. The area of the arc surface of the arc support 1 is larger than or equal to the area of the single arc corrugated plate. The upper surface of the arc-shaped support can be a plane and can also be provided with a surface with corrugated grooves, and the grooves have the same direction with the lines of the corrugated plates and can play a role in fixing the corrugated plates.
A supporting beam is arranged on the inner side of the arc-shaped support 1, the supporting beams are at least two and are arranged in a mutually staggered mode, and the strength and the stability of the arc-shaped support can be improved by arranging the supporting beam 4. The support beam can also have a certain angle, further strengthen the stability of house type support.
The arc-shaped support 1 and the support beam 4 are made of metal, preferably steel.
One side of arc support 1 is equipped with puncher 2, and puncher 2 punches a hole on the ripple of buckled plate outside. The quantity and the interval of the punching machines 2 are the same as those of the bolt holes needing to be punched, and the plurality of punching machines work simultaneously, so that the bolt holes are formed at one time, and the punching efficiency is improved. The perforating machine can also be arranged on two sides of the arc-shaped bracket at the same time, and the two sides are perforated at the same time.
The punch 2 is specifically configured as shown in fig. 3, and includes a punch 5 and a die base 6.
The cross section of the punch 5 is round or kidney-shaped, and a round hole or a kidney-shaped hole can be punched.
The die base 6 is located below the punch 5, and the upper surface of the die base 6 has a radian which is the same as the radian of the corrugation of the corrugated plate. The curved surface is attached to the corrugation of the corrugated plate, so that the corrugated plate can be stably placed on the punching die base 6. The die base 6 may be a separate table or may be integrally formed with the punch base.
The centre of the die base is also provided with a perforation or recess 7 which is able to fully accommodate the punch when it falls to its extreme end.
