Pipe piles, as an important foundation component, are widely used in various civil engineering projects, and square end plates, as an important component of pipe piles, are becoming increasingly diversified. However, the traditional processing and production of square end plates still relies on a large number of manual operations, including manual cutting into long strips, manual cutting into blind plates, manual punching, manual flattening, manual planing, and manual corner punching.

[0020] Embodiment 1 The present invention provides a full-process automatic manufacturing production line for pipe pile square plates. Figures 1 to 9 The shearing device 1 includes a shearing machine 101 and a shearing positioning mechanism 102. The shearing device 1 is used to shear the steel plate into a long strip; the shearing machine 101 includes a frame 101a, a shearing knife seat 101b arranged on one side of the frame 101a, a shearing knife 101c installed in the shearing knife seat 101b, a plurality of pressing plates 101d arranged on one side of the shearing knife seat 101b, a pair of hooks 101e arranged on one side of the frame 101a, and a first driving member 101f arranged on one side of the frame 101a.

[0021] The shear positioning mechanism 102 includes a baffle 102a, a pair of connecting arms 102b fixed on one side of the baffle 102a, a pair of sliding rods 102c arranged on one side of the frame 101a, a connecting block 102d arranged on one side of the connecting arm 102b, and a positioning motor 102e arranged on one side of the connecting block 102d; the connecting arm 102b is placed on the hook 101e, and the connecting arm 102b can drive the baffle 102a to slide on the hook 101e; the shearing machine 101 is arranged between the conveyor belt 701 and the conveyor belt 701; the blade of the shear knife 101c is installed at an angle, and its inclination angle is 5 degrees to 15 degrees; the first driving member 101f uses a hydraulic press as the power output.

[0022] It should be noted that the shearing device 1 is installed between the conveyor belts 701 and 701. The raw material of the pipe pile end plate is sheared from a rectangular steel plate material with an extra-large area. This large steel plate is first lifted to the top of the conveyor belt 701 by a crane, and then passes through the shearing port of the shearing machine 101 after transportation. The width of the long steel plate is then controlled by the shearing positioning mechanism 102. This width should be slightly larger than the side length of the finished square plate to facilitate subsequent milling and reduce errors. The shearing knife 101c is driven by the hydraulic press at its top to press down and shear.

[0023] The working principle of the shear positioning mechanism 102 is as follows: after the large steel plate passes through the shearing opening, it will push the baffle 102a facing the shearing opening. The baffle 102a is fixedly connected to the connecting arm 102b and will move outward as a whole along with the shear positioning mechanism 102. At the same time, the connecting block 102d will slide on the slide bar 102c. When the connecting block 102d moves to a certain position of the slide bar 102c, the position sensor there will be triggered. This process is monitored by the PLC and fed back to the shearing machine 101. The pressing plate 101d falls to press down and fix the steel plate. The bottom of the pressing plate 101d is composed of multiple The pressing block is composed of pressing blocks to evenly press the steel plate to prevent the steel plate from shifting during shearing, resulting in errors caused by uneven shearing. The shear knife 101c then shears the steel plate through hydraulic drive. The shear knife 101c is installed at an angle, which can reduce the contact area between the tool and the steel plate and reduce the cutting resistance, thereby improving the cutting speed and efficiency. After the shearing is completed, the shear positioning mechanism 102 is reset by the positioning motor 102e to repeat the shearing process. After the shearing is completed, the long steel plate is pushed by the steel plate at the rear and falls onto the conveyor belt 701 for transportation to the next process.

[0024] The secondary shearing device 2 includes a plate feeding mechanism 201, a cutting machine 202, and a side-changing mechanism 203 arranged on one side of the cutting machine 201. The secondary shearing device 2 is used to shear the long steel plate into a square blind plate; the plate feeding mechanism 201 includes a conveying platform 201a, a push plate platform 201b arranged above the conveying platform 201a, and a push plate assembly 201c arranged on one side of the push plate platform 201b.

[0025] The push plate platform 201b slides on the conveying platform 201a and is pushed by the second driving member 201d; the push plate assembly 201c includes a bottom plate 201c-1, a bite plate 201c-2 arranged above the bottom plate 201c-1, a lifting rod 201c-3 arranged between the bottom plate 201c-1 and the bite plate 201c-2, and a bite opening 201c-4 arranged on one side of the bite plate 201c-2. The push plate assembly 201c is used to bite the plate material to fix and push it for transportation; the cutting machine 202 includes a lower waste port 202a arranged on its inner bottom surface; the lower waste port 202a is connected to the conveyor belt 701, and the conveyor belt 701 transports the cut waste to the waste well 8; the edge changing mechanism 203 is arranged on the conveying platform 201a, which includes a support platform 203a, and a lifting and rotating member 203b arranged at the bottom of the support platform 203a.

[0026] It should be noted that the transfer from the shearing device 1 to the secondary shearing device 2 is carried out by the robot arm 702. The robot arm 702 uses four electromagnetic suction cups to absorb the four corners of the long square plate, lift and rotate it to the conveyor table 201a, and the landing point is fixed on the conveyor table 201a. The push plate table 204b slides on the conveyor table through the slide rail and is pushed by the second driving member 201d. The second driving member 201d is a cylinder. The bottom plate 201c-1 of the push plate assembly 201c is fixedly connected to the push plate table 204b, and the push plate table 204b pushes the push plate assembly 201c to engage the long steel plate and push it into the cutting machine 202 for feeding and cutting.

[0027] Better, such as Figure 5As shown, the push plate assembly 201c is composed of a bottom plate 201c-1 and a bite plate 201c-2 overlapped up and down, and the two are connected by a lifting rod 201c-3. The position of the bottom plate 201c-1 is kept fixed relative to the push plate platform 204b, and the lifting rod 201c-3 is also controlled by the cylinder to rise and fall to adjust the angle between the two plates, and at the same time to adjust the opening and closing of the bite mouth 201c-4. A layer of anti-slip silicone is attached to the bite mouth 201c-4 to prevent the steel plate from slipping after biting. When the steel plate falls on the conveying platform 201a, the steel plate is fixed and pushed by the sliding rail of the push plate platform 204b and the biting of the lifting rod 201c-3, and is sent into the cutting machine 20 in sequence. 2 is used for cutting, and the cutting is carried out until the last square plate. At this time, the other end of the square plate is not cut, and it is necessary to reverse the cutting to ensure the flatness of the cut. By moving the push plate platform 204b to the other side of the edge-changing mechanism 203, the steel plate is just stopped on the support platform 203a. At this time, the lifting rod 201c-3 descends to release the bite mouth 201c-4 and stays away from the steel plate. The lifting rotating part 203b drives the steel plate to lift and rotate 180 degrees, and then descends to complete the edge-changing. The push plate assembly 201c then pushes the bite steel plate for cutting. Finally, the remaining scraps fall onto the conveyor belt 701 through the lower waste port 202a beside the cutting machine 202 and are transported to the waste well 8.

[0028] Preferably, a leveling device 10 and a long square plate temporary storage device 11 are also provided between the shearing device 1 and the secondary shearing device 2. The long square plate temporary storage device 11 can be a plurality of parallel chain conveyor lines. Because the first cutting process takes a short time, but the subsequent process takes a long time, the long steel plate after the first cutting can be placed on the long square plate temporary storage device, so that a primary shearing machine can match multiple secondary shearing devices. The leveling device uses multiple flattening rollers to simply flatten the long steel plate to ensure the stability of the robot arm 702 during electromagnetic adsorption. The long square plate temporary storage device is composed of a stacking platform made of multiple square steel strips. The long steel plates can be stacked on the stacking platform before the secondary shearing to control the process time and ensure the stable operation of the production line.

[0029] The punching device 3 includes a positioning mechanism 301 and a punching machine 302 arranged above the positioning mechanism 301, and the punching device 3 is used to punch holes on the square blind plate according to product requirements; the positioning mechanism 301 includes a limit rod 301a, limit members 301b arranged on both sides of the limit rod 301a, and a pressure plate 301c arranged above the limit rod 301a, and the pressure plate 301c is provided with a circular hole in the center, and the punching machine 302 is punching the circular hole; the limit rod 301a has an arc edge at the entrance for adjusting the angle of the square plate, and the pressure plate 301b is used to press down the square plate to fix it; the limit member 301b is driven by the cylinders on both sides to open and close; a conveyor belt 701 is arranged below the through hole of the punching machine 302, which is used to transport the waste generated by punching to the waste well 8.

[0030] It should be noted that the positioning mechanism 301 is divided into three directions of positioning, namely, horizontal positioning by the limit rod 301a, positioning of the advancement depth by the limit member 301b, and positioning of the height of the square plate by the pressure plate 301c during the transportation from the conveyor belt 701 to the punching table, so that the position can be fixed during punching to prevent the square plate from shifting during punching and causing a decrease in accuracy. A through hole is opened in the center of the pressure plate 301c to accommodate the punching head through the through hole for punching. There is a pair of limit members 301b, which are respectively located on both sides of the punching machine 302. The limit members 301b are controlled by the cylinder, and the cylinder is pushed, and the limit members 301b are stretched to limit the travel direction of the square plate. At the same time, the pressure plate 301c presses down on the square plate to fix it, and then the punching machine 302 presses down on the square plate to punch. The waste generated by punching falls onto the conveyor belt 701 through the through hole in the center and is transported to the waste well 8.

[0031] The milling device 4 includes a milling table 401, a propulsion mechanism 402 for feeding and pushing, and a conical cylinder 403 for changing edges. The conical cylinder 403 is provided with a pair for rotating the square plate 90 degrees to change edges. The milling device 4 is used to mill the edges of the square plate; the milling table 401 and the propulsion mechanism 402 each include two parts, which respectively mill the two sets of opposite edges of the square plate, and the two parts are separated by a conveyor belt 701; the milling table 401 includes a pair of limit blocks 401a, a milling passage 401b arranged at the bottom of the limit block 401a, a plurality of milling cutter grooves 401c penetrating the limit block 401a, and a plurality of milling cutters 401d arranged in the milling cutter grooves 401c. When the square plate is transported to the top of the milling table 401, the propulsion mechanism 402 will push the square plate through the milling passage 401b, and the square plate will be milled by the milling cutter 401d to mill the edges on both sides of the square plate.

[0032] The propulsion mechanism 402 includes a slide frame 402a, a mounting block 402b fixed to one side of the slide frame 402a, and a strip block 402c hinged to the mounting block 402b; the slide frame 402a is driven by cylinders installed on both sides of the milling table 401 and can slide on the milling table 401; the mounting block 402b includes a stopper 402b-1 facing the side of the inlet drum, which is used to limit the strip block 402c so that the strip block 402c can only be deflected toward the outlet side; the cone cylinder 403 is a conical cylinder, two of which are arranged on the conveyor belt in an upper and lower manner. When the cone cylinder 403 rotates, its nearest surface always remains parallel, and the spacing between them is consistent with the thickness of the square plate. When the square plate passes by, it passes between the two cone cylinders 403, and the upper and lower surfaces contact its nearest surface at the same time, making a steering adjustment of 90 degrees.

[0033] It should be noted that there are two milling tables 401, which respectively mill two pairs of opposite sides of the square plate. The two milling tables 401 are adjusted by 90 degrees of steering through two cones 403. In this embodiment, the opening angle of the cone 403 is 30 degrees. This angle can usually make the square plate generate enough torque when passing through the cone, so as to achieve effective steering. In practical applications, it is recommended to conduct experiments and make adjustments based on the experimental results. You can try different angles and observe the steering effect of the square plate to find the best design parameters. In general, the best method is to conduct prototype testing, adjust the angle and position of the cone according to the actual situation to achieve the desired steering effect, and move to the milling passage 401b of the next milling table 401 after steering, and align the direction with its movement direction after the position of the limit block 401a is adjusted.

[0034] Preferably, the milling cutter groove 401c is opened in the limit block 401a, and six milling cutters 401d are installed on both sides in the milling cutter groove 401c. The milling cutter 401d is fixed by fastening bolts. The required shape of the edge of the square plate can be adjusted by changing the blade shape and installation depth of the milling cutter 401d. In this embodiment, three pairs of milling cutters 401d are used to mill the edge of the square plate into a certain shape, and this shape is used for welding between pipe piles.

[0035] Preferably, after the square plate is transported to the milling passage 401b, the pushing mechanism 402 is used to push the square plate so that it passes through the milling cutter 401d for edge milling. The slide frame 402a in the pushing mechanism 402 is installed above the milling table 401 and can be driven by a motor to slide on the milling table 401.
