Referring to fig. 6, in this embodiment, a transition platform 65 is disposed between two adjacent press-riveting stations 600, and the transition platform is inclined from back to front, so that the pre-pressing member at the previous press-riveting station 600 can enter the next press-riveting station 600 along the transition platform 65 under the action of its own gravity after the press-riveting process is completed. On the other hand, if the front-most press-riveting station 600 is used for machining, the end plate and the skirt plate can smoothly enter the press-riveting station 600 by passing through the lifting plate 64 and the transition platform 65 of the previous press-riveting station 600 in sequence under the action of self gravity when the end plate and the skirt plate are fed.

The main flow of the pipe pile processing production line of the embodiment is as follows:

the discharging wheel 011 of the apron board blank discharging device 01 rotates, and apron board blanks (strip steel) wound on the discharging wheel 011 are sent to the leveling device 02; a straightening roller component 022 of the leveling device 02 levels the strip steel and then sends the strip steel to the cutting device 03 for cutting; the cut skirt board blank is sent into a rolling welding device 04 through a conveyor belt, and the rolling is bent and welded to form an annular skirt board 1 b; the annular apron board is conveyed to a beading device 05 through a first rolling frame 091 to be subjected to beading (indentation) processing treatment, and then is conveyed to a pressure riveting station of the pressure riveting equipment 07 through a second rolling frame 092; meanwhile, the end plate feeding device 06 feeds the end plate to the press riveting station of the press riveting device 07 in a rolling manner; and the end plate 1a and the annular skirt plate 1b are pressed together by the pressing riveting device to finish the pipe pile processing process.

Wherein, the skirtboard is riveted the action process with the end plate pressure and is:

the feeding process of the end plates and the skirting boards comprises the following steps: after the second motor 22 is started, the first transmission rod 31 and the second transmission rod 40 of the transmission mechanism 30 are driven by chains to synchronously transmit, meanwhile, the first transmission chain 32 and the second transmission chain 41 are driven by the two transmission rods to circularly rotate, the material pushing plate 21 drives the end plate 1a stacked on the material storage rack 10 to gradually move from back to front, the end plate at the foremost side of the strip-shaped slideway 101 can slide to the material pushing rack 52 after being shifted to the position of the material outlet 100, then, the air cylinder acts to drive the material pushing rack 52 to rotate upwards, after the material pushing rack 52 rotates (in an inclined state) to a certain degree, the end plate on the material pushing rack 52 can enter the material rolling groove 524 of the material pushing rack 52 under the action of self gravity, roll to one side from the material pushing groove to be far away from the material outlet 100 of the strip-shaped slideway 101, and then enter the end plate guide channel for the riveting rack, and finally, the rivet is positioned in the first positioning notch of the riveting station. After the edge rolling welding is completed in the last process, the apron board 1b can enter an apron board guide channel for a press riveting rack through a feeding platform under the action of self gravity and is finally positioned in a first positioning notch of a press riveting station. Wherein, under the effect of blockking the fifth drive arrangement of clearance mechanism, the pin can shift to the front side of first location breach in order to block end plate and skirtboard to the realization is to the effective positioning of end plate and skirtboard.

The skirtboard rounding and crimping process: under the drive of the seventh driving device 801, after the apron plate rounding device extends into the apron plate and extends in place, the pressing plate of the apron plate rounding device abuts against the end part of the end plate, the cylinder of the apron plate rounding device acts, the piston rod of the cylinder extends out to drive the expansion plate to rotate around the supporting shaft 81, and in the rotation process of the expansion plate, each eccentric convex part 842 (vertex part) of the expansion plate can act on the inner edge of each supporting plate 83, so that each supporting plate 83 is driven to move outwards in the radial direction relative to the fixed plate 82, and the purpose of rounding the apron plate is achieved. After the apron board support circle is in place, the seventh driving device 801 drives the apron board to continue to move towards the end plate pressing mechanism, the end plate in the first positioning notch is pressed on the rotating disc of the end plate pressing mechanism, meanwhile, the apron board is sleeved outside the end plate to form a pre-pressing piece, and the pre-pressing piece is pressed on the rotating disc. Then, the ninth driving device of the end plate pressing mechanism acts, and the rotating disc rotates, so that the pre-pressing piece is driven to rotate. Meanwhile, the fourth driving device of the press riveting mechanism acts to drive the pressing wheel to act on the apron plate of the pre-pressing piece from top to bottom, so that the apron plate is pressed into the groove on the periphery of the end plate by the pressing wheel in the rotating process of the pre-pressing piece, and the press connection process between the apron plate and the pre-pressing piece is completed.

Before the riveting action, the cylinder of the apron plate rounding device 800 is reset, the expansion plate rotates reversely and resets to the initial position, each supporting plate 83 moves inwards in the radial direction relative to the fixed disc 82 under the elastic force action of the corresponding elastic piece and resets to the initial state, the tightening state of the apron plate is released, and the apron plate rounding device 800 does not rotate.

After the crimping is finished, the pressing wheel of the press riveting mechanism resets upwards, the rotating disc of the end plate pressing mechanism stops rotating, and then the seventh driving device of the apron plate supporting mechanism can act to drive the apron plate rounding device to move to the right to reach the initial position.

Finally, block the action of the fifth drive arrangement of clearance mechanism, drive the pin and keep away from the front side of first locating gap, and remove the finished product after accomplishing to process and block, three pressure riveting station in this embodiment corresponds the end plate and the skirtboard of three kinds of different specifications, pressure riveting process is accomplished the back, lifter plate 64 rises, finished product jack-up after accomplishing with processing, because the lifter plate sets up for the slope, the finished product after the crimping is accomplished keeps away from the pressure riveting station in the pressure riveting frame under self action of gravity, roll into the stacking station.
