Referring to fig. 5, when the moving block 26 moves along the sliding groove 25, a situation that the moving block moves perpendicular to the longitudinal direction of the sliding groove 25 may occur, so that the pressing process cannot be performed, and in order to avoid the situation, the cross section of the sliding groove 25 perpendicular to the longitudinal direction thereof is set to be an inverted "T" shape, a portion of the moving block 26 corresponding to the sliding groove 25 is attached to the inner wall of the sliding groove 25, and a portion of the pressing plate 41 corresponding to the sliding groove 25 is attached to the inner wall of the sliding groove 25. Through the arrangement, the moving block 26 cannot move in the direction perpendicular to the length direction of the sliding groove 25, so that the stability of the moving block 26 sliding in the sliding groove 25 is improved, and the smooth operation of hole opening is ensured.

The implementation principle of the embodiment is as follows: when processing packing box installing support, the first step is buckled at the station of buckling and is processed: the pushing plate 14 is pushed vertically upwards by using an ejector rod of a machine tool until the upper surface of the placing plate 12 is flush with the top surfaces of the lower pressing block I10 and the lower pressing block II 11, the plate is placed on the placing plate 12, the limiting column 29 is inserted into the limiting hole 31, then the upper die base I3 is moved vertically downwards, when the upper pressing block I6 is attached to the plate, the placing plate 12 and the upper pressing block I6 synchronously move vertically downwards, so that the upper pressing block I6 presses the plate into the placing groove 9, and the plate is finally clamped by the upper pressing block I6, the lower pressing block I10, the lower pressing block II 11 and the placing plate 12, so that bending processing is completed; and step two, hole opening processing is carried out at a punching station: the bent plate is placed on the placing table 21, the upper die base II 15 is vertically moved downwards, the upper pressing block II 19 is vertically moved downwards to press the plate on the placing table 21, the cutting block 38 is vertically moved downwards to cut off the limiting piece 30, the extruding block 28 is vertically moved downwards to push the moving block 26, the ejector rod 27 and the pressing plate 41 to move towards the direction close to the placing table 21, the pressing plate 41 is firstly pressed on the plate, then the ejector rod 27 penetrates through the pressing plate 41 and the plate and is finally inserted into the first insertion groove 22, and therefore hole opening operation of the plate is completed. To sum up, at first buckle the station to panel and buckle the processing and obtain the panel after buckling, then carry out the trompil operation to the panel after buckling at the station that punches a hole, can obtain the packing box installing support, because buckle the operation earlier and carry out the trompil operation again, consequently the position of mounting hole 2 can not change, the utility model discloses have the effect that can not change the position of mounting hole 2 when processing packing box installing support.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
