Description

Technical Field

[0001] This utility model relates to the field of rigid pipe fitting connection technology, specifically to an automated riveting and slag-removing device for a movable joint of a pipe fitting base. Background Technology

[0002] Pipe fittings are frequently used in the construction of frames or supports. Movable joints are used in areas requiring rotation, and these joints are connected via riveting. A movable joint is a pipe connector that is easy to install and disassemble. It is commonly used to distribute the load transmitted by the frame uprights, enhancing the overall stability of the frame. It is frequently found at the bottom of ground-supported scaffolding or frames to ensure stability and safety. This component includes a metal base with ground mounting holes at the bottom, which is bolted to the ground for stable support; it also includes a cylindrical connecting sleeve for fitting onto the frame uprights. Connecting plates on the two components are connected by rivets, enabling a rotatable connection between the uprights and the base.

[0003] Ideally, when riveting equipment connects a metal base and a connecting sleeve, the rivet's end continuously extends and deforms during the impact and extrusion molding process, gradually forming a smooth, rounded arc-shaped rivet head under the action of the mold. However, in actual production, due to factors such as the stability of the rivet material, fluctuations in the riveting machine's working condition, and mold matching, the final rivet often has a lot of burrs and residues adhering to the edge of the rivet head, affecting the product's aesthetics, posing safety hazards during use, and being prone to corrosion. To remove these burrs and residues, manufacturers need to assign dedicated personnel to manually clean each connector using wire brushes, which is labor-intensive, time-consuming, and creates a poor working environment at the processing station. Summary of the Invention

[0004] To address the aforementioned issues, this utility model provides an automated riveting and slag-removing device for movable joints of pipe fitting bases. This device automatically removes burrs and residues from riveted and assembled movable joints of pipe fitting bases, and centrally collects and processes the removed burrs and residues. This improves product quality and production efficiency while ensuring a superior working environment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automated riveting and slag-removing device for a movable joint of a pipe fitting base, used to connect a metal base 1 and a connecting sleeve 2 together by rivets, and to clean burrs and residues from the riveting area, characterized in that it includes an automatic tabletop riveting mechanism, an automatic parts feeding mechanism, and a slag-removing mechanism for the riveting area.

[0006] The automatic tabletop riveting mechanism includes a machine body 3, a power motor 4, an upper riveting die 5, a lower riveting die 6, and a working platform 7. The machine body 3 is the basic carrier of the entire equipment, providing support for other components, and the front of the machine body 3 has reserved space to accommodate the working platform 7 and the riveting die assembly. The power motor 4 is installed on the top of the machine body 3, with its output shaft facing downwards, and is connected to the transmission gearbox 8 and the upper riveting die 5. The working platform 7 is located directly below the power motor 4. The working platform 7 has a flat surface and is provided with a T-shaped positioning groove for adjusting and fixing the lower riveting die 6. A hydraulic cylinder is installed below the working platform 7, and the vertical position of the working platform 7 and the lower riveting die 6 installed on it can be adjusted by lifting. The upper riveting die 5 and the lower riveting die 6 are axially aligned, and both of their contact surfaces are provided with concave forming holes. A control panel is also provided on the side of the machine body 3, which integrates a digital display screen, control buttons, and knobs to display working parameters in real time.

[0007] The automatic parts feeding mechanism includes two parts, left and right, respectively arranged on both sides of the automatic table riveting mechanism. The part on the left side of the automatic table riveting mechanism is a vertically arranged metal base feeding mechanism, and the part on the right side of the automatic table riveting mechanism is a horizontally arranged connecting sleeve feeding mechanism.

[0008] The metal base feeding mechanism includes an open-type feed hopper 9, a discharge channel 10, and a telescopic feeding arm 11. The bottom of the open-type feed hopper 9 is provided with a discharge port, the shape of which is consistent with the side projection shape of the metal base 1, but slightly larger in size. The operator puts the metal base 1 into the discharge port one by one, so that it enters the discharge channel 10 and moves downward along the discharge channel 10 under its own gravity. At the bottom of the discharge channel 10, there is a hollow section. The bottom of the hollow section is provided with a receiving plate 10-1. The right side of the hollow section is hollowed out, and a telescopic feeding arm 11 is provided. The hollow area is the horizontal movement space of the telescopic feeding arm 11. An elastic baffle 10-2 is provided on its left side, which can be bent and reset, and is responsible for stabilizing the metal base 1 that falls on the receiving plate 10-1.

[0009] The telescopic feeding arm 11 includes a cylinder fixed to the outside of the bottom of the material drop channel 10, and a telescopic rod connected to the telescopic shaft of the cylinder. The telescopic rod includes two horizontal conical rods 11-1, which are smaller in the front and larger in the back, and a mounting base 11-2 for the horizontal conical rods 11-1. The axes of the two horizontal conical rods 11-1 coincide with the ground mounting holes provided on the metal base 1, and can pass through the ground mounting holes to move the metal base 1 forward as a whole.

[0010] At the upper edge of the hollow section at the bottom of the material feeding channel 10, a damped one-way feeding wheel 10-3 is installed on the side wall. Feeding teeth are distributed on the wheel, and a metal base 1 is accommodated between any two feeding teeth. Rotating the feeding wheel one standard increment feeds a metal base 1 downwards. Simultaneously, a one-way spring 11-3 is installed on the upper surface of the mounting base 11-2 of the horizontal conical rod 11-1 located below the material feeding channel 10. This spring 11-3 can retract downwards and lock upwards. Moving the conical rod 11-1 forward pushes the metal base 1, which rests on the receiving plate 10-1, forward. When the one-way spring 11-3 contacts the feeding gear 10-3, it will retract downwards, and the feeding gear 10-3 will not be moved and will not rotate, and the metal base 1 in the dropping channel 10 will remain stable; when the conical rod 11-1 is retracted, the one-way spring 11-3 will lock when it encounters the feeding gear 10-3 in the opposite direction, causing the feeding gear 10-3 to rotate one standard scale, and the dropping channel 10 will convey one metal base 1 downwards to fall onto the receiving plate 10-1, and the remaining metal bases 1 will move down in sequence and wait for the next rotation of the feeding gear 10-3.

[0011] The connecting sleeve feeding mechanism adopts a horizontal structure, including a rotary conveyor belt 12. Each unit of the rotary conveyor belt 12 is equipped with an air-expanding sleeve 13 to grasp and release the connecting sleeve 2. The rotary conveyor belt 12 rotates, sending the connecting plate of the connecting sleeve 2 to the upper mold 6 of the rivet head, where it aligns with the connecting plate on the metal base 1 sent by the metal base feeding mechanism. The power motor 4 and the working platform 7 work simultaneously, and the upper mold 5 and the lower mold 6 of the rivet head press against each other. The upper mold 5 of the rivet head rotates simultaneously, connecting the metal base 1 and the connecting plate on the connecting sleeve 2 together with rivets.

[0012] The slag removal mechanism at the riveting part includes two slag removal brushes 14 installed at the rear end of the rotary conveyor belt 12, facing each other. Both brushes are connected to a motor and driven to rotate. After the metal base 1 and the connecting sleeve 2 are riveted together, they become a movable joint. The upper mold 5 and the lower mold 6 of the riveting joint separate, and the movable joint continues to be clamped by the air-expanding sleeve 13 on the rotary conveyor belt 12, which then conveys one end of the connecting sleeve 2 backward. When the riveting part of the movable joint rotates between the upper and lower slag removal brushes 14, the slag removal brushes 14 rotate to clean the two rivet heads on the movable joint. After cleaning, the rotary conveyor belt 12 continues to rotate and rotates to the top of the collection box 15. The air-expanding sleeve 13 then releases, and the movable joint falls into the collection box 15, thus completing the entire process.

[0013] The cleaning brush 14 is surrounded by a semi-circular dust cover, with a dust collection box below it. Beneficial effects

[0014] This utility model achieves high efficiency, high quality, and cleanliness in the production of movable joints for pipe fitting bases through automated integrated design, precise structural optimization, and environmentally friendly treatment mechanisms, significantly improving overall production efficiency. The equipment described in the application integrates three core functions: riveting, feeding, and slag removal, realizing full automation from parts loading to finished product collection, reducing manual intervention and labor intensity.

[0015] First, the riveting and slag removal processes are carried out simultaneously, which can shorten the processing time per station. The metal base feeding mechanism, through the cooperation of the telescopic feeding arm 11 and the unidirectional feeding wheel 10-3, achieves precise feeding one by one. The connecting sleeve feeding mechanism uses the conveyor belt 12-1 and the rotary conveyor track 12 in coordination to ensure positioning accuracy and avoid manual placement errors. The concave forming hole design of the upper and lower molds of the riveting joint ensures the precise alignment of the rivet and the connecting plate, reducing riveting deformation and burr generation. The slag removal brush 14 adopts an up-and-down relative rotation design, which can simultaneously clean the burrs and residues of the two rivet heads, ensuring that the surface finish meets the requirements.

[0016] In addition, this application also includes a residue collection mechanism, with a dust collection box installed below the cleaning brush 14, which, together with a dust cover, effectively collects the metal burrs and dust generated during the cleaning process, thus avoiding environmental pollution.

[0017] Furthermore, the riveting, feeding, and slag removal mechanisms in this application are independently installed, which facilitates maintenance and component replacement; the working platform 7 is vertically adjustable via a hydraulic cylinder to adapt to the riveting requirements of parts of different specifications and improve the equipment's versatility; the telescopic feeding arm 11 adopts a conical rod 11-1 design to reduce friction with the mounting holes of the metal base 1 and extend its service life.
