Description

Technical Field

[0001] The invention relates to the technical field of pipe pile processing, and in particular to a riveting device for riveting a skirt plate to an end plate. Background Art

[0002] Prestressed concrete precast piles (pipe piles) are a kind of concrete products, which are widely used in industrial and civil construction, highways, railways, water conservancy, ports and docks and other fields. In order to facilitate the connection of prestressed concrete precast piles, end plates need to be installed at both ends of the concrete precast piles. Before making prestressed concrete precast piles, the end plates need to be riveted or welded to the strip steel (skirt plate). Among them, the side circumferential surface of the end plate is provided with a groove. After the end plate is inserted into the skirt plate, the skirt plate part needs to be pressed into the groove of the end plate to form a groove structure, so as to make the connection between the two more firmly. At present, the above operation is generally performed manually, which is inefficient.

[0003] In order to solve the above technical problems, the Chinese invention patent application with application number CN201710220823.9 (publication number CN107008813A) discloses "A kind of clamp riveting equipment for producing various specifications", including: a frame, an end plate placing table, a clamp skin placing table, an end plate transfer mechanism, a clamp skin transfer mechanism, a riveting mechanism, a clamp skin positioning mechanism, and an end plate positioning and rotating mechanism; the end plate transfer mechanism travels back and forth between the riveting mechanism and the end plate placing table through a linear track to transfer the end plate; the clamp skin transfer mechanism travels back and forth between the riveting mechanism and the clamp skin placing table through a linear track to transfer the clamp skin; the clamp skin positioning mechanism and the end plate positioning and rotating mechanism are both arranged at the riveting mechanism, and the riveting mechanism rivets and fixes the positioned end plate and the clamp skin. The riveting process is as follows: after the end plate is loaded and positioned, it is automatically transported to the riveting station. Then the cylindrical strip is loaded and positioned, and is automatically transported to the riveting station. It is riveted with the end plate in one go. After the riveting is completed, the finished clamp is automatically sent to the finished product unloading place. The whole process is fully automated. At the same time, after adjustment, the whole set of equipment can realize the production of clamps of various specifications.

[0004] The riveting equipment in the above patent still has certain shortcomings in actual use. First, the end plate and the skirt plate (hoop skin) need to be transported to the riveting station through the corresponding end plate transfer mechanism and the hoop skin transfer mechanism. The structure of the end plate and hoop skin transfer mechanism is relatively complex, and the transfer process is relatively cumbersome, resulting in low efficiency of the riveting process. Secondly, when the riveting equipment is used for riveting of pipe piles of different specifications (i.e., the sizes of the end plates and skirt plates are different), it is necessary to replace the corresponding positioning mechanism or adjust the positioning mechanism. The replacement or adjustment process is relatively complicated, so the adaptability is relatively poor, and it is difficult to meet the diverse processing needs of producers.

[0005] Therefore, the existing riveting equipment for pipe pile processing needs to be further improved. Summary of the invention

[0006] The first technical problem to be solved by the present invention is to provide a riveting device for riveting the skirt plate to the end plate, which can effectively simplify the loading process, realize the rapid positioning of the end plate and the skirt plate, and thus improve the riveting processing efficiency.

[0007] The second technical problem to be solved by the present invention is to provide a riveting device for riveting the skirt plate to the end plate, which can be applied to the riveting process of pipe piles of different specifications, in view of the current status of the prior art.

[0008] The technical solution adopted by the present invention to solve the first technical problem is: a riveting device for riveting a skirt plate to an end plate, comprising a frame, an end plate clamping mechanism, a skirt plate supporting mechanism and a riveting mechanism, the frame having a riveting station for positioning the end plate and the skirt plate, the end plate clamping mechanism and the skirt plate supporting mechanism are both arranged on the frame and close to the riveting station, the end plate clamping mechanism comprises a rotating disk for pressing the end surface of the end plate, the skirt plate supporting mechanism is used to fix the skirt plate placed on the riveting station, and can drive the skirt plate to move toward the end plate clamping mechanism, so that the skirt plate is sleeved outside the end plate to form a pre-pressed member, and the end plate clamping mechanism is used to fix the skirt plate placed on the riveting station, and can drive the skirt plate to move toward the end plate clamping mechanism, so that the skirt plate is sleeved outside the end plate to form a pre-pressed member, and the end plate clamping mechanism is used to fix the skirt plate placed on the riveting station, and can drive the skirt plate to move toward the end plate clamping mechanism, so that the skirt plate is sleeved outside the end plate to form a pre-pressed member, and the end plate clamping mechanism is used to fix the skirt plate The pre-pressing part is pressed on the rotating disk, and the rotating disk can rotate around its own axis, thereby driving the pre-pressing part to rotate. The riveting mechanism is arranged on the frame and is located on one side of the riveting station, including a pressing wheel that can act laterally on the pre-pressing part. The pressing wheel can press the skirt plate into the groove of the peripheral edge of the end plate during the rotation of the pre-pressing part. The end plate pressing mechanism and the skirt plate supporting mechanism are respectively located on the left and right sides of the riveting station. The riveting station is provided with a positioning notch for vertical placement of the end plate and the skirt plate. The front and rear sides of the positioning notch can be limited on the peripheral edge of the end plate and the circumferential part of the skirt plate, thereby forming support for the end plate and the skirt plate upward.

[0009] In order to form the above positioning notch, simplify the structure of the riveting equipment, and reduce production costs, the frame has two first support rods arranged side by side and at intervals, and the two first support rods are respectively located at the front and rear sides of the riveting station, so that the positioning notch is jointly defined by the two first support rods. The spacing between the above two first support rods can be flexibly set according to the specifications and dimensions of the corresponding workpieces (end plate and skirt plate), and assembly is very convenient. It can be imagined that the setting of the positioning notch is not limited to the above first support rods, for example, it can also be formed by cutting on a flat plate.

[0010] In order to realize the loading of the skirt board, it also includes a loading platform for conveying the skirt board to be processed to the positioning notch of the riveting station. The loading platform is arranged on the frame and located upstream of the positioning notch.

[0011] In order to realize automatic feeding of the skirt board, the feeding platform can be in the form of a conveyor belt for transmission, but in order to simplify the structure of the feeding platform and adapt to the above-mentioned positioning notch, the feeding platform is a transmission plate arranged downwardly from the back to the front, and the height of the front edge of the transmission plate is basically consistent with the height of the first support rod located at the rear side of the riveting station, so that the skirt board can roll along the transmission plate to the positioning notch under the action of its own gravity. This structural design can replace other existing conveyor belts or manipulator devices, which not only saves production costs, but also eliminates the conventional manipulator grabbing and transfer actions, and improves feeding efficiency.

[0012] In order to prevent the skirt plate, especially the end plate, from deflecting or tipping over during the rolling process and failing to smoothly enter the corresponding riveting station, an end plate guide channel and a skirt plate guide channel are provided on the frame corresponding to the riveting station. The length directions of the end plate guide channel and the skirt plate guide channel are consistent with the extension direction of the conveying plate, the width of the end plate guide channel matches the thickness of the end plate, and the width of the skirt plate guide channel matches the axial length of the skirt plate.

[0013] In order to simplify the structure of the end plate guide channel and the skirt plate guide channel, a guide frame that can be lifted up and down is provided on the frame, and the guide frame includes two first limit rods which are arranged in parallel and whose length direction is consistent with the extension direction of the conveying plate. The two first limit rods are located above the riveting station, thereby jointly defining the skirt plate guide channel. The rotating disk of the end plate clamping mechanism and the adjacent first limit rods jointly define the end plate guide channel.

[0014] In order to realize automatic unloading after the riveting process is completed, it also includes a lifting platform device arranged in the positioning notch for receiving the end plate and the skirt plate, the lifting platform device includes a lifting plate arranged to be tilted downward from the back to the front, and the lifting plate can rise to a position consistent with the edge height of the positioning notch, so that the pre-tightening part can roll forward under its own gravity after the riveting process is completed, and move away from the riveting station.

[0015] In order to realize automatic loading of the end plate, an end plate loading device is also included, and the end plate loading device includes:

[0016] The material storage rack comprises a strip slide with a material discharge port, and the end plates are arranged vertically in sequence along the length direction of the strip slide;

[0017] An end plate conveying mechanism is provided on the material storage rack and can act on the end plates placed in the strip slide of the material storage rack, so as to push the end plates to the discharge port of the strip slide in the order in which they are placed;

[0018] The end plate transfer mechanism includes a first driving device and a pusher rack. The pusher rack is arranged at the discharge port of the strip slideway and is used to receive the end plate coming out of the discharge port of the strip slideway. The power output end of the first driving device is connected to the pusher rack, so as to drive the end plate shifted to the pusher rack away from the discharge port of the strip slideway. The end plate on the pusher rack can roll into the end plate guide channel and finally enter the positioning notch of the riveting station of the frame.

[0019] The technical solution adopted by the present invention to solve the second technical problem is: at least two riveting stations are arranged on the frame from back to front, the spacing of the positioning notches on each riveting station in the front-to-back direction matches the end plates and skirt plates of different specifications, the height of the positioning notch located at the front riveting station is lower than the height of the positioning notch located at the rear riveting station, and a transition platform inclined from back to front is provided between the two riveting stations, so that the pre-tightening parts on the previous riveting station can enter the next riveting station along the transition platform under the action of their own gravity after the riveting process is completed.

[0020] In order to make the loading process of the end plate and the skirt plate more stable and reliable, a blocking and releasing mechanism is also provided on the frame, and the blocking and releasing mechanism includes a blocking rod movably arranged on one side of the riveting station, and the blocking rod can be shifted to the front side of the positioning notch to block the end plate and the skirt plate, and can be moved away from the front side of the positioning notch to release the blocking of the end plate and the skirt plate.

[0021] In order to drive the above-mentioned baffle rod to achieve the purpose of blocking and releasing the end plate and skirt plate, the first end of the baffle rod is hinged on the frame, and the power output end of the fifth drive device is connected to the baffle rod through a linkage rod, thereby driving the baffle rod to swing up and down.

[0022] Compared with the prior art, the advantages of the present invention are as follows: the positioning notches provided on the riveting station of the frame enable the end plates and skirt plates to be placed vertically, and when the end plates and skirt plates enter the positioning notches, they can automatically achieve accurate positioning of the two, and then the pre-assembly of the end plates and skirt plates can be achieved by the end plate clamping mechanisms and skirt plate support mechanisms provided on the left and right sides of the riveting station, and finally the riveting process can be completed by the side action of the clamping wheel of the riveting mechanism on the pre-assembled skirt plate. This structural setting effectively simplifies the loading process of the end plates and skirt plates, and can achieve rapid positioning of the end plates and skirt plates, thereby improving the riveting process efficiency. In particular, in the preferred embodiment, it is only necessary to set up a plurality of riveting stations, and to set positioning notches of different sizes on each riveting station, so as to achieve riveting of pipe piles of different specifications, thereby greatly saving production costs and meeting the riveting process requirements of producers for pipe piles of different specifications.

[0046] The present invention is further described in detail below with reference to the accompanying drawings.

[0047] See also Figure 1-Figure 23 A riveting device for riveting a skirt plate to an end plate includes a frame 60, an end plate clamping mechanism 70, a skirt plate supporting mechanism 80, a riveting mechanism 90, an end plate feeding device 1, a blocking and releasing mechanism 92 and a lifting platform device.

[0048] See also Figure 1 The frame 60 has at least one riveting station 600, and the riveting station 600 has a positioning notch 601 for vertical placement of the end plate 1a and the skirt plate 1b. The front and rear sides of the positioning notch 601 can be limited on the periphery of the end plate and the circumference of the skirt plate, thereby supporting the end plate and the skirt plate upward and achieving positioning of the two. "Vertical placement of the end plate and the skirt plate" means that the axis of the end plate and the skirt plate is basically horizontal.

[0049] See also Figure 2 The frame 60 is a rectangular frame on which a plurality of riveting stations 600 can be arranged. As shown in this embodiment, three riveting stations 600 are arranged in sequence and spaced apart along the length direction of the frame 60.

[0050] See also Figure 3 and Figure 4 In order to form the positioning notch 601, the frame 60 has two first support rods 61 arranged side by side and spaced apart, and the two first support rods 61 are respectively located at the front and rear sides of the riveting station 600, so that the positioning notch 601 is jointly defined by the two first support rods 61. The spacing between the two first support rods 61 can be flexibly set according to the specifications and dimensions of the corresponding workpieces (end plate and skirt plate), and assembly is very convenient.

[0051] In order to facilitate the rotation of the end face and the skirt plate during the riveting process and reduce resistance, the first support rod 61 of this embodiment itself can rotate around its own axis, or a rotating body that can rotate freely around the first support rod is provided on the first support rod 61, and the circumferential edge of the end face and the circumferential part of the skirt plate are in contact with the rotating body.

[0052] See also Figure 1A loading platform is also provided on the frame 60 at the upstream of the positioning notch 601, and the loading platform can be used to transfer the skirt board 1b to be processed to the positioning notch 601 of the riveting station 600. In order to realize the automatic loading of the end plate 1a and the skirt board 1b, the loading platform can be in the form of a conveyor belt for transmission, but in order to simplify the structure of the loading platform and adapt to the positioning notch 601, the loading platform is a conveying plate 62 arranged to be tilted downward from the back to the front, and the height of the front side edge of the conveying plate 62 is substantially consistent with the height of the first support rod 61 located at the rear side of the riveting station 600, so that the skirt board can roll along the conveying plate 62 to the positioning notch 601 under the action of its own gravity.

[0053] See also Figure 1 The two side edges of the conveying plate 62 are folded upward to form two retaining edges, thereby preventing the skirt plate from deflecting or falling during the rolling process.

[0054] The end plate of this embodiment is also loaded in a rolling manner, and the end plate loading device and the end plate loading process are described in detail below.

[0055] See also Figure 3 In order to prevent the skirt plate, especially the end plate, from deflecting or tipping during the rolling process and failing to smoothly enter the corresponding riveting station 600, the frame 60 is further provided with an end plate guide channel 631 and a skirt plate guide channel 632 corresponding to the riveting station 600. The length directions of the end plate guide channel 631 and the skirt plate guide channel 632 are consistent with the extension direction of the conveying plate 62, the width of the end plate guide channel 631 matches the thickness of the end plate, and the width of the skirt plate guide channel 632 matches the axial length of the skirt plate.

[0056] Combination Figure 4 and Figure 5 In order to simplify the structure of the end plate guide channel 631 and the skirt plate guide channel 632, a guide frame 633 capable of being lifted up and down is provided on the frame 60. The guide frame 633 includes two first limit rods 634 arranged in parallel and having a length direction consistent with the extension direction of the conveying plate 62. The two first limit rods 634 are located above the riveting station 600, thereby jointly defining the skirt plate guide channel 632. The rotating disk 71 of the end plate pressing mechanism 70 and the adjacent first limit rods 634 jointly define the end plate guide channel 631.

[0057] See also Figure 5, a vertical bracket 602 is provided on the frame 60 corresponding to the left side of the riveting station 600, and the bracket 602 has an auxiliary arm 6021 extending horizontally to the top of the riveting station 600, and the auxiliary arm 6021 is provided with an eighth driving device 635, and the power output end of the eighth driving device 635 is connected to the above-mentioned two first limiting rods 634 through a vertically arranged suspension rod. The eighth driving device 635 of this embodiment can be selected as a driving cylinder. The guide frame 633 can be moved to different height positions under the action of the driving cylinder, so as to realize the guiding and limiting of skirt boards and end boards of different specifications.

[0058] See also Figure 1 and Fig.13 The end plate feeding device includes a storage rack 10, an end plate conveying mechanism 20 and an end plate transfer mechanism 50. The storage rack 10 has a strip slide 101, and the strip slide 101 allows the end plates 1a to be placed vertically in sequence along the length direction of the strip slide 101, that is, the ends are stacked from back to front in the strip slide 101, and the front part of the strip slide 101 has an opening, which is the discharge port 100 for the end plates to be moved out, see Fig.16 .

[0059] See also Fig.14 The strip slide 101 of the storage rack 10 is tilted upward from the back to the front, wherein the angle between the strip slide 101 and the horizontal plane is α, specifically, 5°<α<45°, preferably, α is 15°. The strip slide 101 is tilted upward so that the end plate placed in the strip slide 101 is slightly tilted backward, thereby preventing the end plate from tipping forward after being transported to the right position and stopping during the transport process, thereby causing a material blockage problem at the discharge port 100.

[0060] See also Fig.15 In order to simplify the structure of the storage rack 10, the storage rack 10 of this embodiment includes a rectangular frame 11. The rectangular frame 11 has a second limiting rod 111 extending longitudinally to limit the left and right sides of the end plate, and a second supporting rod 112 longitudinally arranged to support the bottom of the end plate, wherein the spacing between the two second limiting rods 111 is equal to or slightly smaller than the diameter of the corresponding end plate. The two second limiting rods 111 and the second supporting rod 112 together define the above-mentioned strip slide 101.

[0061] The end plate conveying mechanism 20 is arranged on the storage rack 10 and can act on the end plates 1a placed in the strip slide 101 of the storage rack 10, so as to push the end plates to the discharge port 100 of the strip slide 101 in the order of placement.

[0062] See also Fig.13 and Fig.14 The end plate conveying mechanism 20 includes a second motor 22 , a transmission mechanism 30 and a push plate 21 .

[0063] See also Fig.19 The push plate 21 is slidably arranged in the strip slide 101, and can abut against the end plate placed at the rearmost position in the strip slide 101. Specifically, the periphery of the push plate 21 in this embodiment is a semicircular arc, and its curvature is basically consistent with the curvature of the periphery of the end plate.

[0064] See also Fig.17 The transmission mechanism 30 includes a first transmission unit located at the bottom and a second transmission unit located at the top. The first transmission unit corresponds to the two second limit rods 111 and is connected to the upper side of the push plate 21. The second transmission unit corresponds to the second support rod 112 and is connected to the lower side of the push plate 21.

[0065] The first transmission unit includes a first transmission rod 31 and a first transmission chain 32. The first transmission rod 31 is arranged at the rear position of the rectangular frame 11, arranged along the width direction of the strip slide 101, and rotatably connected to the rectangular frame 11. Specifically, both ends of the first transmission rod 31 are connected to the above-mentioned rectangular frame 11 through bearings. The first transmission rod 31 is coaxially provided with a first sprocket 33, a second sprocket 34 and a third sprocket 35. The power output shaft of the second motor 22 is provided with a driving sprocket 220, which is connected to the first sprocket 33 through a chain, thereby driving the first transmission rod 31 to rotate around its own axis. The first transmission chain 32 is arranged along the length direction of the strip slide 101, the rear end of the first transmission chain 32 is connected to the second sprocket 34 of the first transmission rod 31, and the front end of the first transmission chain 32 is connected to the auxiliary sprocket provided on the rectangular frame 11. More specifically, the first transmission chain 32 is also connected to the above-mentioned push plate 21 through the first connecting plate 36 , so that when the first transmission chain 32 is in motion, it can drive the push plate 21 to move along the strip slide 101 .

[0066] The second support rod 112 of this embodiment adopts a channel steel structure, and the first transmission chain 32 adopts a double-row large roller chain with a U-shaped cover plate, and is accommodated in the notch of the channel steel. The lower part of the end plate 1a is placed on the U-shaped cover plate of the first transmission chain 32, and the roller of the first transmission chain 32 acts on the channel steel. When the first transmission chain 32 pushes the end plate 1a forward, the roller can roll on the wall surface of the channel steel. In order to clearly show other related components in the figure, the first transmission chain 32 is not shown in full.

[0067] The second transmission unit includes a second transmission rod 40 and a second transmission chain 41. The second transmission rod 40 is also arranged at the rear position of the rectangular frame 11, and the second transmission rod 40 is arranged along the width direction of the strip slide 101, and is rotatably connected to the rectangular frame 11. Specifically, the two ends of the second transmission rod 40 are connected to the above-mentioned rectangular frame 11 through bearings. The second transmission rod 40 is coaxially provided with a fourth sprocket 42 and two fifth sprockets 43. The fourth sprocket 42 is transmission-connected to the third sprocket 35 through a chain. There are two second transmission chains 41 in this embodiment, extending along the length direction of the strip slide 101. The two second transmission chains 41 correspond to the second limit rods 111 one by one, and the two second transmission chains 41 are transmission-connected to the two fifth sprockets 43 on the second transmission rod 40 respectively. The two second transmission chains 41 in this embodiment are both connected to the two sides of the push plate 21 through the second connecting plate 44. The two second limit rods 111 of this embodiment are of channel steel structure, and the notches of the two channel steels are arranged oppositely. Correspondingly, the two second transmission chains 41 are roller chains and are received in the notches of the channel steels. In order to clearly show other related components in the figure, the second transmission chain 42 is not shown completely.

[0068] The second motor 22 is disposed at the bottom of the rectangular frame 11. When the second motor 22 is in motion, it can drive the first transmission unit and the second transmission unit to move synchronously, thereby pushing the end plate placed in the strip slide 101 to move forward. This transmission mode makes the movement process of the end plate in the strip slide 101 more reliable and stable.

[0069] See also Fig.15 and Fig.16 The end plate transfer mechanism 50 is correspondingly arranged at the front position of the storage rack 10, and specifically includes a first driving device 51 and a pushing rack 52. The pushing rack 52 is correspondingly arranged at the discharge port 100 of the strip slide 101, and is used to receive the end plate coming out of the discharge port 100 of the strip slide 101. The power output end of the first driving device 51 is connected to the pushing rack 52, so that the end plate shifted to the pushing rack 52 can be driven away from the discharge port 100 of the strip slide 101.

[0070] See also Fig.16 In order to better utilize the circular outer peripheral structural characteristics of the end plate and simplify the structure of the end plate transfer mechanism 50, the pusher frame 52 is a strip frame, which is arranged along the width direction of the strip slide 101. The first end of the strip frame is hinged to one side of the discharge port 100 of the strip slide 101, and the power output end of the first driving device 51 is connected to the second end of the strip frame, so that the strip frame can be driven to swing up and down. In the process of the second end of the strip frame swinging upward, it is in an inclined state, and the end plate shifted to the strip frame can roll to one side under the action of its own gravity and away from the discharge port 100 of the strip slide 101.

[0071] See also Fig.18 The pusher frame 52 includes a baffle plate 521, a horizontal push plate and a limit plate 523. The baffle plate 521 is vertically extended corresponding to the discharge port 100 of the strip slide 101. The horizontal support plate 522 is formed by bending from the lower edge of the baffle plate 521 toward the discharge port 100. When the strip frame moves down to a low position, the horizontal support plate 522 is flush with or lower than the edge of the discharge port 100 of the strip slide 101. The limit plate 523 is also vertically arranged and connected to the rear side of the horizontal support plate 522, so as to be spaced relative to the baffle plate 521, wherein the height position of the upper part of the limit plate 523 is lower than the height position of the upper part of the baffle plate 521. Specifically, the limit plate 523 in this embodiment is located at the side of the discharge port 100 of the strip slide 101, so as to avoid interference with the process of the end plate in the strip slide 101 moving to the horizontal support plate 522 of the push rack 52. The width of the horizontal support plate 522 is adapted to the thickness of one end plate. Specifically, the limit plate 523, the horizontal support plate 522 and the baffle plate 521 together form a rolling groove 524 for only one end plate to be vertically accommodated therein. When the push rack 52 moves upward, the end plate can roll along the length direction of the rolling groove 524 and move away from the discharge port 100 of the strip slide 101, thereby achieving the purpose of single transfer and loading of the end plates stacked on the push rack 52. Among them, the rolling groove 524 is connected with the end plate guide channel 631 described below.

[0072] In order to allow the end plate to smoothly enter the rolling groove 524, the side edge of the limiting plate 523 close to the discharge port 100 is bent and extended toward the side away from the baffle plate 521 to form a bending portion 525, and a guide opening 526 for guiding the end plate to enter the rolling groove 524 is formed between the bending portion 525 and the baffle plate 521.

[0073] The first driving device 51 of this embodiment can be selected as a first motor or a cylinder. For the flexibility of the end plate transfer process and cost considerations, the first driving device 51 is preferably a cylinder. The cylinder body of the cylinder is rotatably connected to the storage rack 10, and the end of the piston rod of the cylinder is rotatably connected to the second end of the strip rack.

[0074] See also Figure 4 and Fig. 20The lifting platform device is arranged in the positioning notch 601, and is used to receive the end plate and skirt plate transferred from the upstream of the riveting station 600. The lifting platform device includes a lifting plate 64 and a third driving device 641. The third driving device 641 adopts a cylinder, which is connected to the frame 60, and the end of the piston rod of the cylinder is connected to the bottom of the lifting plate 64. When the cylinder is in motion, it can drive the lifting plate 64 to move up and down. The lifting plate 64 of this embodiment is tilted downward from the back to the front. Among them, the lifting plate 64 can rise to a position consistent with the edge height of the positioning notch 601, so that the end plate and the skirt plate can roll forward under their own gravity after the riveting process is completed, and move away from the riveting station 600, so as to realize automatic unloading. On the other hand, when loading, the lifting plate 64 rises and is in a high position. At this time, the end plate and the skirt plate can roll onto the lifting plate 64, and be limited on the front side of the positioning notch 601 by the blocking rod 920 of the release mechanism 92. After the end plate and the skirt plate stay on the lifting plate 64 , the lifting plate 64 moves downward until the end plate and the skirt plate fall on the two first support rods 61 , thereby realizing rapid positioning of the end plate and the skirt plate.

[0075] Since the positioning notch 601 of the present embodiment is defined by two first support rods 61, when the lifting plate 64 rises to the set position, the height of the rear edge of the lifting plate 64 is substantially consistent with the height of the first support rods 61 on the rear side of the positioning notch 601, and the height of the front edge of the lifting plate 64 is substantially consistent with the height of the first support rods 61 on the front side of the positioning notch 601.

Specifically, the first end of the linkage rod 921 is hinged to the power output end of the cylinder, and the second end of the linkage rod 921 is connected to the first end of the blocking rod 920. Under the driving action of the cylinder, the blocking rod 920 can swing downward to the front side of the positioning notch 601 to block the end plate and the skirt plate, and can swing upward and away from the front side of the positioning notch 601, thereby releasing the blocking of the end plate and the skirt plate. The setting of the blocking direction mechanism makes the loading process of the end plate and the skirt plate more stable and reliable, see for details. Figure 6 .

Specifically, at least two riveting stations 600 are arranged on the frame 60 from back to front.

The spacing of the positioning notches 601 on each riveting station 600 on the frame 60 in the front-to-back direction matches the end plates and skirt plates of different specifications, and the height of the positioning notch 601 located at the front riveting station 600 is lower than the height of the positioning notch 601 located at the rear riveting station 600.

[0097] See also Figure 6 In this embodiment, a transition platform 65 tilted from the back to the front is provided between two adjacent riveting stations 600, so that the pre-compressed parts on the previous riveting station 600 can enter the next riveting station 600 along the transition platform 65 under the action of their own weight after the riveting process is completed. On the other hand, if the frontmost riveting station 600 is used for processing, the end plate and the skirt plate can be smoothly loaded into the riveting station 600 by passing through the lifting plate 64 of the previous riveting station 600 and the transition platform 65 in sequence under the action of their own weight.

[0098] The action process of the riveting device for riveting the skirt plate to the end plate in this embodiment is as follows:

[0099] Loading process of end plate and skirt plate:

[0100] 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 to transmit synchronously through the chain. At the same time, the first transmission chain 32 and the second transmission chain 41 are driven by the above two transmission rods to rotate cyclically, and the end plate 1a stacked on the storage rack 10 is driven by the push plate 21 to move gradually from back to front. After the end plate located at the front side of the strip slide 101 shifts to the position of the discharge port 100, it will slide onto the push rack 52, and then, the cylinder is actuated to drive the push rack 52 to rotate upward. After the push rack 52 rotates (tilted state) to a certain extent, the end plate on the push rack 52 will enter the rolling groove 524 of the push rack 52 under the action of its own gravity, and roll to one side from the push groove away from the discharge port 100 of the strip slide 101, and then enter the end plate guide channel for the frame, and finally be positioned in the positioning notch of the riveting station. After the skirt plate 1b is rolled and welded in the previous process, it can enter the skirt plate guide channel for the frame through the loading platform under its own gravity, and finally be positioned in the positioning notch of the riveting station. Under the action of the fifth driving device of the blocking and releasing mechanism, the blocking rod can be shifted to the front side of the positioning notch to block the end plate and the skirt plate, thereby achieving effective positioning of the end plate and the skirt plate.

[0101] Skirt board support rounding and crimping process:

[0102] Driven by the seventh drive device, after the skirt board rounding device extends into the skirt board and is in place, the pressing plate of the skirt board rounding device abuts against the end of the end plate, the cylinder of the skirt board rounding device is actuated, and the piston rod of the cylinder extends, driving the expansion plate 84 to rotate around the support shaft 81. During the rotation of the expansion plate 84, the eccentric protrusions 842 (vertex parts) of the expansion plate 84 can act on the inner edge of each support plate 83, thereby driving each support plate 83 to move radially outward relative to the fixed plate 82, thereby achieving the purpose of rounding the skirt board. After the skirt board is rounded in place, the seventh drive device drives the skirt board to continue to move toward the end plate clamping mechanism, and presses the end plate in the positioning notch on the rotating disk of the end plate clamping mechanism. At the same time, the skirt board is set outside the end plate to form a pre-pressing member, and the pre-pressing member is pressed on the rotating disk. Then, the ninth drive device of the end plate clamping mechanism is actuated, and the rotating disk rotates, thereby driving the pre-pressing member to rotate. At the same time, the fourth driving device of the riveting mechanism is activated, driving the clamping wheel to act on the skirt plate of the pre-pressing member from top to bottom. In this way, during the rotation of the pre-pressing member, the clamping wheel presses the skirt plate into the groove on the peripheral edge of the end plate, completing the crimping process between the two.

[0103] Before the riveting action, the cylinder of the skirt board supporting device 800 is reset, the expansion plate 84 rotates in the opposite direction and resets to the initial position, and each supporting plate 83 moves radially inward relative to the fixed disk 82 under the elastic force of the corresponding elastic member 85 and resets to the initial state, releasing the tension state of the skirt board, that is, the skirt board supporting device 800 does not rotate.

[0104] After the crimping is completed, the clamping wheel of the riveting mechanism resets upward, the rotating disk of the end plate clamping mechanism stops rotating, and then the seventh driving device of the skirt plate supporting mechanism can be activated to drive the skirt plate supporting device to move rightward to the initial position.

[0105] Finally, the fifth driving device of the blocking and releasing mechanism is actuated to drive the blocking rod away from the front side of the positioning notch, thereby releasing the obstruction to the finished product after processing. The three riveting stations in this embodiment correspond to end plates and skirt plates of three different specifications. After the riveting process is completed, the lifting plate 64 rises to lift the finished product after processing. Since the lifting plate is inclined, the finished product after crimping moves away from the riveting station on the frame under the action of its own gravity and rolls into the stacking station.
