Round pipe end flattening device and round pipe flattening structure
The invention relates to the technical field of round pipe end flattening, in particular to a round pipe end flattening device and a round pipe flattening structure.The round pipe end flattening device comprises a round pipe end, and the round pipe end is sequentially provided with an inclined part and a horizontal part in the direction towards the tail end of the round pipe end; the end part of the round pipe is provided with the inclined part, the horizontal part, the side edge curled parts and the through holes, the inner side of the inclined part is provided with the inclined part, the horizontal part, the side edge curled parts and the through holes, the inside of each side edge curled part is hollow, and the inner side of each side edge curled part is hollow. The side edge curled parts are arranged on the two sides of the penetrating hole, on one hand, the bolt penetrating through the penetrating hole can be limited through the arrangement of the side edge curled parts, due to the fact that the side edge curled parts are hollow, the side edge curled parts can deform to a certain degree after being stressed, and bolt heads used for connection can be conveniently embedded into the side edge curled parts; and the bolt is prevented from being stressed, rotated and loosened after long-time use.
本发明涉及圆管端部打扁技术领域，尤其为一种圆管端部打扁装置及圆管打扁结构，包括圆管端部，所述圆管端部朝向其末端的方向依次设置有倾斜部和水平部，所述倾斜部和水平部的两侧均固定连接有用于增加刚度和起到限位作用的侧边卷曲部，所述水平部的内侧设置有用于起到连接作用的穿孔，本发明中的圆管端部设置有倾斜部、水平部、侧边卷曲部和穿孔，侧边卷曲部内部中空，侧边卷曲部设置在穿孔的两侧，侧边卷曲部的设置一方面能够起到对穿过穿孔内的螺栓进行限位，其中，因为侧边卷曲部内部中空，侧边卷曲部受力后，能够产生一定的形变，便于用于连接的螺栓头嵌入在侧边卷曲部内，防止螺栓长时间使用后受力旋转松脱。
