Description

Technical Field

[0001] The utility model relates to a punching machine, in particular to a split side hole punching machine for wide plates. Background Art

[0002] Before C-shaped steel is roll-formed, a punching machine is needed to punch holes on both sides of the sheet. The punching machines currently used in production lines are mainly Figure 6 The column-type integrated punching machine shown in the figure comprises a top plate and a bottom plate. The top plate and the bottom plate are fixedly connected at their four corners by columns. The cylinder body of the punching cylinder is installed outside the top of the top plate. The telescopic cylinder of the punching cylinder is located under the top plate and a punching die is installed. This punching machine is mainly suitable for narrow plates with a small width. One punching cylinder and a set of punching dies can be used to complete the punching of the edge holes on both sides of the plate. For wide plates with a slightly larger width, a punching cylinder and a set of punching dies need to be respectively provided on both sides of the wide plate. See Figure 7 At this time, the two punching cylinders and two sets of punching dies are mainly supported by the top plate. Since the middle part of the top plate is suspended without support, in order to improve the strength of the top plate, the top plate needs to be thickened, resulting in a heavier overall weight and high cost. In addition, when the width of the sheet changes, the general method is to disassemble the punching cylinder and the punching die, adjust the position along the horizontal adjustment hole, and then fix it with bolts after adjustment, which is more troublesome to disassemble.

Before punching the wide plate A, first adjust the position of the two split plate frames 2 through the sliding drive device 9 so that the wide plate channel is larger than the width of the wide plate A, ensuring that the wide plate A can pass through the punching machine. When the positions of the two split plate frames 2 are adjusted, place the wide plate A through the wide plate channel and place it on the upper surface of the punching lower die 6, and use the vertical roller adjustment device 8 to respectively abut against the two side ends of the wide plate A to limit the longitudinal position of the wide plate A. At this time, the punching positions of the punching upper die 5 and the punching lower die 6 are just located on the side of the wide plate A. Then punching starts, and the two long hole cylinders descend at the same time, driving the punching upper die 5 to punch the wide plate A downward, forming side holes on both sides of the wide plate A.
