Technical Field

[0001] The utility model relates to the technical field of I-beam web punching processing, in particular to a limiting wheel set of an I-beam web punching machine. Background Art

[0002] Arc-shaped I-beams are a type of I-beams, which refer to long strips of steel with an I-shaped cross-section. The I-beams are mainly composed of general wing plates and webs. Considering that they need to be fixed to mechanical equipment by bolts later, a punching machine is generally required to punch holes in the webs of the arc-shaped I-beams. In fact, when the existing punching machines perform punching operations on the arc-shaped I-beams inserted from the side ends, the arc-shaped I-beams need to be pushed forward along the center point position for multiple times during processing in order to perform multiple punchings. The unrestricted arc-shaped I-beams lose weight at their side ends, and are very likely to deviate and slide on the processing table, which also affects the continued normal operation of the punching machine. Therefore, in view of the above problems, a limiting wheel set for an I-beam web punching machine is proposed. Utility Model Content

[0006] Preferably, a die seat is fixedly installed at the middle position of the top end of the punching base plate, and an arc-shaped I-beam body is placed directly above the die seat, and the die seat is arranged at the center position of the three limiting wheels.

[0007] Preferably, the front end of the column is fixedly connected with an inclined plate, and the inclined plate and the transfer tray are fixedly connected, the two sides of the central slide groove are adjacent to each other and the side slide groove and the transfer tray are integrally formed, the transfer tray is slidably connected to the side slide groove through the side guide column, and the lower half of the side slide groove is slidably connected to the inside of the side slide groove.

[0008] Preferably, a shaft retaining spring is provided on the upper outer part of the short cylinder, and a hole retaining spring is provided on the lower outer part of the short cylinder. The inner side of the limiting wheel is provided with grooves that are engaged with the bearing and the hole retaining spring, respectively.
