Prestressed concrete prefabricated piles (pipe piles), as a concrete product, are widely used in industrial and civil buildings, roads, railways, water conservancy, port terminals and other fields. In order to facilitate the connection of prestressed concrete precast piles, the two ends of the concrete precast piles need to be installed with end plates. Before making the prestressed concrete prefabricated pile, the end plate and the strip steel (skirt plate) need to be riveted or welded first. Wherein, the side circumferential surface of the end plate is provided with a groove. After the end plate is clipped into the skirt plate, the skirt plate part needs to be pressed into the groove of the end plate to form a pressure groove structure, so that the connection between the two is more convenient. It is firm. Currently, the above operations are generally carried out manually, and the efficiency is low.

In order to solve the above technical problems, the Chinese utility model patent application with the application number CN202022634971.5 (authorized announcement number is CN213968673U) discloses a riveting machine for riveting the skirt plate to the end plate, including a frame, an end plate press The frame has a riveting station, and the skirt plate support mechanism is used to fix the skirt plate, and can drive the skirt plate to move toward the end plate pressing mechanism, so that the skirt plate is sleeved A pre-pressing part is formed outside the end plate, and the rotating disk can rotate around its own axis to drive the pre-pressing part to rotate, and the pressing wheel of the riveting mechanism can act on the pre-pressing part laterally to realize the connection between the end plate and the skirt The crimping, end plate pressing mechanism and skirt plate supporting mechanism are respectively located on the left and right sides of the riveting station. The riveting station has a positioning gap for the vertical placement of the end plate and skirt plate. The side edge can be limited on the peripheral edge of the end plate and the peripheral portion of the skirt plate, so as to support the end plate and the skirt plate upward.

After the skirt plate is rounded in place, the second cylinder 32 drives the skirt plate to continue moving towards the end plate pressing mechanism 2, and press the end plate in the positioning gap 120 onto the rotating disk 20 of the end plate pressing mechanism 2, At the same time, the skirt plate is sheathed outside the end plate to form a pre-pressing part, and the pre-pressing part is pressed on the rotating disk 20 . Then, the first motor 21 of the end plate pressing mechanism 2 operates, and the rotating disk 20 rotates, thereby driving the pre-pressing part to rotate. At the same time, the sixth cylinder 42 of the riveting mechanism 4 acts to drive the pressing wheel 41 to act on the skirt plate of the pre-pressing part from top to bottom, so that during the rotation of the pre-pressing part, the pressing wheel 41 will The skirt plate is pressed into the groove on the periphery of the end plate to complete the crimping process between the two.

During the riveting process, each support plate 333 of the skirt plate rounding assembly can always be in an exposed state, that is, maintain a rounded state for the skirt plate, thereby improving the riveting effect. After the riveting is completed, the third cylinder 335 is reset, and the expansion plate rotates in the opposite direction, and resets to the initial position. Under the action of the elastic force of the corresponding elastic member 336, each support plate 333 moves inward relative to the radial direction of the fixed plate 332. Reset to the initial state and release the tight state of the skirt.

After the crimping is completed, the pressure wheel 41 of the pressure riveting mechanism 4 resets upwards, and the rotating disk 20 of the end plate pressure mechanism 2 stops rotating. Then, the second cylinder 32 of the skirt board supporting mechanism can move to drive the skirt board to support the circle. The component moves position to the right to the original position.

The skirt board support mechanism of the riveting machine of this embodiment includes at least two skirt board support assemblies 31. When skirt boards of different sizes need to be rounded and fixed to be assembled with corresponding end boards, the corresponding skirt boards can be supported The assembly 31 moves to a position corresponding to the riveting station 10 of the frame 1, that is, the rounding operation of skirt plates of different sizes can be carried out at a fixed position, so that there is no need to set multiple Riveting station 10, the overall volume of the riveting machine is reduced, saving space; on the other hand, since the rounding operation of skirt plates of different sizes can be performed at a fixed position, the end plate and skirt board feeding process The moving path in the machine can be shortened as much as possible, which improves the efficiency of the riveting process.
