[0027] At present, most of the links in the production process of embedded casing structures require manual operation or rely on multiple independent processing equipment to be completed in sequence. The labor cost is high, and the coordination between multiple production links is poor. The embedded casing structure needs to be frequently switched between different processing equipment, and the production process has poor continuity, resulting in low production efficiency.

[0028] The present invention proposes a production line for a pre-embedded casing structure, which is used to produce the pre-embedded casing structure. The pre-embedded casing structure includes a casing 100, a spiral rib 200 and a fixed tube 300. The production line for the pre-embedded casing structure includes a casing feeding mechanism 10, a spiral rib forming machine 20, a cutting mechanism, a screwing mechanism 30, a first clamping mechanism 40, a second clamping mechanism 50, a first conveyor belt 60 and a second conveyor belt 70. The cutting mechanism and the screwing mechanism 30 are arranged at intervals on the first conveyor belt 60; the casing feeding mechanism 10 includes a feeding port 11 and a discharging port 12, and the discharging port 12 is aligned with the first conveyor belt 60. The casing feeding mechanism 10 is used to place the casing 100 on the first conveyor belt 60, and the first conveyor belt 60 can convey the casing 100 to the cutting mechanism. The cutting mechanism is used to cut the casing 100 to form a thread on the outer wall of the casing 100. The spiral rib forming machine 20 is used to Bending into a spiral rib 200, the first clamping mechanism 40 is arranged between the spiral rib forming machine 20 and the first conveyor belt 60, the first clamping mechanism 40 is used to clamp the spiral rib 200 formed by the spiral rib forming machine 20 and place the spiral rib 200 in the screwing mechanism 30, the first conveyor belt 60 can convey the sleeve 100 cut by the cutting mechanism to the screwing mechanism 30, the screwing mechanism 30 is used to screw the spiral rib 200 into the thread so that the spiral rib 200 is sleeved on the outside of the sleeve 100, the second clamping mechanism 50 is arranged between the first conveyor belt 60 and the second conveyor belt 70, the second clamping mechanism 50 can clamp the sleeve 100 with the spiral rib 200 sleeved on the first conveyor belt 60 and place it on the second conveyor belt 70, and the second clamping mechanism 50 can clamp the fixing tube 300 and sleeve the fixing tube 300 on the outside of the spiral rib 200 to form a pre-buried sleeve structure.

[0029] See also Figure 1The first conveyor belt 60 is arranged in an annular shape. The sleeve feeding mechanism 10, the cutting mechanism (not shown), and the screwing mechanism 30 are respectively arranged on the outer periphery of the first conveyor belt 60. The first clamping mechanism 40 is arranged between the spiral bar forming machine 20 and the screwing mechanism 30. The spiral bar forming machine 20 is used to process the steel bar into the spiral bar 200. The first clamping mechanism 40 can clamp the formed spiral bar 200 and move it to the screwing mechanism 30. The sleeve feeding mechanism 10 is used to sequentially supply the sleeves 100 to the first conveyor belt 60. The sleeves 100 are transported by the first conveyor belt 60 and enter the cutting mechanism. The cutting mechanism cuts the side wall of the sleeve 100 to form a thread. The first conveyor belt 60 then transports the threaded sleeve 100 to the screwing mechanism 30. The screwing mechanism 30 can screw the spiral rib 200 onto the sleeve 100 along the thread, so that the spiral rib 200 is wound around the outside of the sleeve 100. The second clamping mechanism 50 is arranged between the first conveyor belt 60 and the second conveyor belt 70. The second clamping mechanism 50 clamps the sleeve 100 with the spiral rib 200 and moves it to the second conveyor belt 70. The second clamping mechanism 50 can clamp the fixed tube 300 and sleeve the fixed tube 300 on the outside of the spiral rib 200, so that the sleeve 100, the spiral rib 200 and the fixed tube 300 are sequentially sleeved from the inside to the outside to form a pre-buried sleeve structure, and are conveyed to subsequent processing equipment through the second conveyor belt 70.

[0030] In the production line for the embedded casing structure proposed in the present invention, the casing feeding mechanism 10 continuously supplies casing 100 to the first conveyor belt 60. The cutting mechanism precisely cuts threads on the outer wall of the casing 100. The spiral rib forming machine 20 processes the steel bars into spiral ribs 200. The first clamping mechanism 40 transfers the formed spiral ribs 200 to the screwing mechanism 30, where they are screwed and fixed to the threads on the outer surface of the casing 100. The second clamping mechanism 50 transfers the casing 100, with the spiral ribs 200, to the second conveyor belt 70. A fixing cylinder 300 is installed on the outer surface of the screwing mechanism, ultimately forming the embedded casing structure. By integrating the sleeve feeding mechanism 10, the spiral rib forming machine 20, the cutting mechanism, and the screwing mechanism 30 into one, the entire process from sleeve 100 feeding, sleeve 100 cutting, spiral rib 200 forming, spiral rib 200 installation to fixing tube 300 installation can be automated, thereby realizing the automated production of the embedded sleeve structure. The various mechanisms have good coordination, which can significantly improve the production efficiency of the embedded sleeve structure, effectively reduce labor costs, and ensure the consistency and stability of the production quality of the embedded sleeve structure.

[0031] In one embodiment, the spiral rebar forming machine 20 includes a winding drum 21, a straightening assembly 22, a hydraulic cutting device, a bending assembly 23 and a feeding drive arranged in sequence. The feeding drive is used to transfer the steel bars wound by the winding drum 21 to the straightening assembly 22, the hydraulic cutting device and the bending assembly 23 in sequence. The straightening assembly 22 is used to straighten the steel bars, the hydraulic cutting device is used to cut the steel bars into steel bar segments, and the bending assembly 23 is used to bend the steel bar segments into spiral rebars 200.

[0032] See also Figure 2 The steel bars are received on the winding drum 21, and the feeding drive transmits the steel bars to the straightening assembly 22. The straightening assembly 22 can straighten the steel bars and eliminate the bending deformation caused when the steel bars are received on the winding drum 21; the straightened steel bars can be transmitted to the bending assembly 23 under the drive of the feeding drive, so that the ends of the steel bars enter the bending assembly 23, and the middle part of the steel bars are passed through the hydraulic cutting device; the hydraulic cutting device can cut the continuous steel bars into steel bar segments of preset lengths, and the bending assembly 23 can bend the steel bar segments according to the preset bending angle to form spiral bars 200. Through the coordinated operation of the straightening assembly 22, the hydraulic cutting device, the bending assembly 23 and the feeding drive, from the winding of the winding drum 21 to the straightening of the straightening assembly 22, and then to the cutting by the hydraulic cutting device and the bending forming by the bending assembly 23, the automated continuous operation of the spiral bar 200 processing is realized, effectively improving the production efficiency.

[0033] In one embodiment, the straightening assembly 22 includes a plurality of rollers 221 , which are arranged in two rows at intervals, with a straightening channel for the steel bars to pass through formed between the two rows of rollers 221 .

[0034] Furthermore, in the process of the steel bars passing through the straightening channel, the upper and lower rows of rollers 221 rotate synchronously towards each other, providing multi-point support and compression to the steel bars, so that the bending stress of the steel bars caused by the winding of the winding drum 21 is gradually eliminated, and the steel bars are output from the straightening channel in a straightened state, so as to facilitate entering the subsequent hydraulic cutting device and bending component 23.

[0035] In one embodiment, the bending assembly 23 includes a bending roller 231, a pressure block 232 and a servo slide. The pressure block 232 is spaced apart from the bending roller 231, and the pressure block 232 can swing toward or away from the bending roller 231. The servo slide is connected to the rotating shaft of the bending roller 231. The servo slide can drive the bending roller 231 to rotate, and the servo slide can drive the bending roller 231 to slide along its axial direction.

[0036] Please continue reading Figure 2The pressing block 232 is swingably disposed within the bending assembly 23. After the rebar enters the bending assembly 23, the pressing block 232 swings toward the bending roller 231 to compress the rebar between the pressing block 232 and the bending roller, bending the rebar at a preset angle. Simultaneously, the servo slide drives the bending roller 231 to slide axially, causing the rebar to bend and displace axially simultaneously, forming the spiral rebar 200. By changing the swinging direction of the pressing block 232, the spacing between the pressing block 232 and the bending roller 231 is changed, thereby adjusting the bending angle of the rebar, thereby meeting the production requirements of spiral rebars 200 of different sizes.

[0037] In one embodiment, the sleeve feeding mechanism 10 includes a hopper 13 and a feeding trough 14. The hopper 13 is tapered from top to bottom. A feeding port 15 is provided at the bottom of the hopper 13. The feeding trough 14 is connected between the feeding port 15 and the first conveyor belt 60, and the bottom of the feeding trough 14 is tilted downward from the feeding port 15 to the first conveyor belt 60.

[0038] See also Figure 3 The hopper 13 is configured to stack the sleeves 100. The hopper 13 is tapered from top to bottom, allowing the sleeves 100 stacked in the hopper 13 to gradually slide toward the feed port 15 at the bottom under the action of gravity and enter the feed chute 14. The feed chute 14 is tilted, allowing the sleeves 100 to slide along the feed chute 14 toward the first conveyor belt 60 under the action of gravity after exiting the feed port 15, ensuring smooth sliding of the sleeves 100. By changing the tilt angle of the feed chute 14, the sliding speed of the sleeves 100 can be adjusted to match the feeding speed of the sleeves 100 with the conveying speed of the first conveyor belt 60, ensuring stable and smooth loading of the sleeves 100.

[0039] In one embodiment, the first clamping mechanism 40 includes a first robotic arm 41, a connecting disk 42, a first driving member and a plurality of first clamping claws 43. The connecting disk 42 is connected to the first robotic arm 41. The plurality of first clamping claws 43 are installed on the side of the connecting disk 42 away from the first robotic arm 41. The first driving member can drive the plurality of first clamping claws 43 to move closer to or away from each other to correspondingly clamp or release the sleeve 100.

[0040] See also Figure 4The first driving member drives each first clamping claw 43 to move synchronously to clamp or release the sleeve 100. Specifically, when clamping the sleeve 100, the first driving member drives the first clamping claws 43 to move closer to each other. The multiple first clamping claws 43 are evenly distributed on the edge of the connecting plate 42, and can simultaneously apply clamping force to the sleeve 100 from different directions, so that the sleeve 100 is stably clamped. When releasing the sleeve 100, the first driving member drives the multiple first clamping claws 43 away from each other, loosening the clamping of the sleeve 100, and facilitating the removal and placement of the sleeve 100. Through the cooperation of the first driving member and the multiple first clamping claws 43, the sleeve 100 can be clamped and released quickly and stably.

[0041] In one embodiment, the screwing mechanism 30 includes a bracket, a lifting rod, a third clamping assembly, a lifting motor and a screwing motor. The bracket is arranged on the first conveyor belt 60, the lifting motor is installed on the bracket, the movable end of the lifting motor is connected to one end of the lifting rod, the lifting motor can drive the lifting rod to rise and fall, and the screwing motor is arranged at the other end of the lifting rod. The output shaft of the screwing motor is connected to the third clamping assembly that can clamp or loosen the spiral rib 200, and the screwing motor can drive the third clamping assembly to rotate.

[0042] It should be noted that the bracket is connected to the edge of the first conveyor belt 60, so that the screwing mechanism 30 is fixed relative to the first conveyor belt 60, and a screwing channel is formed in the bracket for the first conveyor belt 60 to pass through. After the first conveyor belt 60 conveys the threaded casing 100 into the bracket, the third clamping assembly clamps the spiral rib 200, and the lifting motor drives the lifting rod to lower, driving the third clamping assembly connected to the lifting rod to lower, so that the spiral rib 200 clamped by the third clamping assembly contacts the casing 100. As the third clamping assembly is lowered, the screwing motor drives the third clamping assembly to rotate, gradually screwing the spiral rib 200 into the thread, thereby sleeved the threaded rib on the outside of the casing 100. Through the coordinated work of the bracket, lifting rod, third clamping assembly, lifting motor and screwing motor, the precise screwing operation of the spiral rib 200 is achieved, ensuring that the screwing depth and force of the spiral rib 200 are uniform, avoiding structural loosening or damage caused by improper screwing, and effectively improving the installation accuracy of the spiral rib 200, thereby ensuring the molding quality of the sleeve 100 structure.

[0043] In one embodiment, the third clamping assembly includes a third driving member and a plurality of third clamping claws. The third driving member can drive the plurality of third clamping claws to move closer to or farther from each other to clamp or release the spiral rib 200 accordingly.

[0044] It can be understood that there are multiple third clamping claws, and the third driving member can drive the multiple third clamping claws to move closer to or away from each other to clamp or loosen the spiral rib 200 accordingly, thereby achieving precise clamping and installation of the spiral rib 200, effectively improving the mechanization level of the screwing mechanism 30, thereby improving the assembly efficiency of the sleeve 100 structure and reducing labor intensity.

[0045] In one embodiment, a positioning cavity is opened in the sleeve 100, and a positioning hole connected to the positioning cavity is formed at the bottom end of the sleeve 100. The first conveyor belt 60 and the second conveyor belt 70 are both provided with positioning pins that can be plugged into the positioning cavity.

[0046] It can be explained that the sleeve 100 is firmly connected to the first conveyor belt 60 and the second conveyor belt 70 through the plug-in cooperation between the positioning cavity and the positioning pin. When the sleeve 100 is subjected to operations such as cutting, the displacement of the sleeve 100 structure is avoided, thereby effectively ensuring the molding quality of the sleeve 100 structure.

[0047] The present invention also provides a track plate production line, which includes a production line for a pre-embedded casing structure. The specific structure of the production line for the pre-embedded casing structure is similar to that of the above-mentioned embodiments. Since the production line for the track plate adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described in detail here. Among them, the production line for the pre-embedded casing structure can continuously produce the pre-embedded casing structure, achieve stable material supply to the production line of the track plate, and realize automated production of the track plate, effectively improving the production efficiency of the track plate.
