Description

Technical Field

[0001] This invention relates to the technical field of metal insert grinding equipment, specifically to an integrated processing equipment for long-life rubber skeleton metal inserts. Background Technology

[0002] In the production process of rubber skeleton metal inserts such as shock absorber bearings and suspension bushings, the core process is to bond the surface-treated metal skeleton and the mixed rubber in a mold at high temperature. Existing equipment mostly adopts a single-cavity hot-press vulcanization method. After the metal skeleton is put into the mold cavity, the mold is closed and the rubber is injected. Heat is conducted through the upper and lower hot plates to vulcanize the rubber and bond it to the metal surface. However, after long-term storage or pretreatment, the surface of the metal skeleton is prone to forming a micro-oxidation layer or adsorbing moisture. If it is not fully activated before vulcanization, the rubber and metal interface will be difficult to form a strong chemical bond and physical interlock. This interface defect is not obvious in the early stage of product stress, but under long-term alternating load and thermo-oxidative aging, the defect will gradually develop into microcracks and extend along the interface, eventually causing the rubber layer to peel off and de-adhere from the metal skeleton, significantly shortening the service life of the product. In addition, the single hot plate conduction heating method results in a large temperature gradient in the thick-walled mold cavity. The vulcanization rate in the central area far from the heat source lags behind that of the surface layer, causing uneven crosslinking density in different parts of the same product. This further aggravates the risk of interfacial stress concentration and fatigue failure, becoming the main technical bottleneck restricting the long-term reliable service of rubber skeleton inserts. To address this, we propose an integrated processing equipment for long-life rubber skeleton metal inserts. Summary of the Invention

[0003] One of the technical problems to be solved in this application is: how to design a long-life integrated processing equipment for rubber skeleton metal inserts that ensures stability when the rubber and metal skeleton are in contact.

[0004] To address the aforementioned technical problems, this application provides an integrated processing equipment for long-life rubber skeleton metal inserts, comprising a base, a collection cylinder and an activation cylinder disposed on the top of the base, wherein the top of the activation cylinder is provided with a discharge hopper communicating with its interior, a rotating disk is movably disposed inside the activation cylinder, and a motor is disposed on the top of the base to drive the rotating disk to rotate, and further comprising: Multiple air pumps are provided on the top of the base. A grooving removal cylinder is disposed inside the activation cylinder, and multiple cylinders are provided therein, for scraping off the oxide layer on the outer surface of the metal skeleton; A rotary scraping mechanism is located between the motor and the rotating disk. It is used to drive multiple slotted removal cylinders to rotate inside the activation cylinder to remove the oxide layer on the metal skeleton and to introduce an inert protective gas to prevent secondary oxidation of the metal surface after activation. The extrusion mechanism is located inside the activation cylinder and is used to apply radial elastic force to each slotted removal cylinder, so that it elastically fits against the outer surface of the metal skeleton.

[0005] In some embodiments, the rotary scraping mechanism includes a mounting plate disposed at the end of the rotating disk, a support rod disposed at the end of the mounting plate, an inert gas driving device disposed at one end of the support rod, and a straight rod disposed at the end of the inert gas driving device.

[0006] In some embodiments, a rotating disk is provided at the end of the straight rod, one end of the rotating disk is connected to the output end of the motor, and the outer surface of the rotating disk is provided with connecting rods corresponding to a plurality of slotted removal cylinders, the ends of the plurality of connecting rods being connected to the outer surface of the corresponding air cylinder.

[0007] In some embodiments, the end of the connecting rod connected to the air cylinder is telescopic, which is used to buffer and limit the movement of the groove removal cylinder by telescopic extension of the end of the connecting rod and suppress large shaking when the air cylinder drives the groove removal cylinder to move.

[0008] In some embodiments, one end of the air cylinder is connected to the slotted removal cylinder, the other end of the air cylinder is provided with an installation cylinder, the end of the installation cylinder is provided with a hose, the outer surface of the hose is covered with a protective tube, the end of the protective tube passes through a connecting rod and is connected to the inert gas driving device, and the end of the hose is connected to the interior of the inert gas driving device.

[0009] In some embodiments, an inner cylinder is movably disposed inside the air cylinder, the end of the inner cylinder is connected to the slotted removal cylinder, the end of the inner cylinder is provided with a plurality of inclined rods, the end of the plurality of inclined rods is provided with a central disk, the end of the central disk is provided with a shaft, and the outer surface of the shaft is provided with a plurality of blades.

[0010] In some embodiments, the extrusion mechanism includes a collar sleeved on the outer surface of the air cylinder, a second side plate is provided at one end of the mounting plate, a spring is provided on the side of the second side plate, a first side plate is provided at the other end of the spring, and a push plate is provided on the side of the first side plate.

[0011] In some embodiments, the push plate has an arc-shaped groove on its side, the inner side of the arc-shaped groove is movably disposed on the outer surface of the collar, the end of the rotating disk has a sliding groove, and the outer side of the slotted removal cylinder is movably disposed on the inner side of the sliding groove.

[0012] This invention has at least the following beneficial effects: 1. By setting a slotted removal cylinder to rotate at high speed inside the activation cylinder along with the rotating disk, the oxide layer on the outer surface of the metal skeleton is removed by centrifugal friction. At the same time, an inert gas driving device supplies gas into the slotted removal cylinder through a hose and a gas cylinder, so that the inert gas is evenly discharged from the slot and coats the surface of the metal skeleton. This not only achieves surface activation treatment but also prevents secondary oxidation of the metal surface after activation, effectively enhancing the chemical bonding strength of the rubber-metal interface in the subsequent vulcanization process.

[0013] 2. By setting a spring in the extrusion mechanism to elastically connect side plate one and side plate two, when the contact between the grooving removal cylinder and the metal skeleton is obstructed, the collar drives the push plate to slide along the slide and compress the spring to produce elastic yielding, so that the grooving removal cylinder can adapt to the outer surface of the metal skeleton of different shapes and sizes, avoiding rigid collision damage caused by the misalignment or shape deviation of the metal skeleton. At the same time, the spring rebound force can ensure that the grooving removal cylinder always adheres to the skeleton surface with constant pressure, ensuring uniform and consistent oxide layer removal effect.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] For examples, please refer to Figure 1-7 This invention provides a technical solution: a long-life rubber skeleton metal insert integrated processing equipment, including a base 1, a collection cylinder 2 and an activation cylinder 6 disposed on the top of the base 1, a discharge hopper 4 connected to the inside of the activation cylinder 6, a rotating disk 8 movably disposed inside the activation cylinder 6, and a motor 3 disposed on the top of the base 1 to drive the rotating disk 8 to rotate, and further including: Air pump 5 is located on the top of base 1, and multiple of them are provided; The grooving removal cylinder 10 is located inside the activation cylinder 6, and there are multiple of them, used to scrape off the oxide layer on the outer surface of the metal skeleton. The rotary scraping mechanism 7 is located between the motor 3 and the rotating disk 8. It is used to drive multiple slotted removal cylinders 10 to rotate inside the activation cylinder 6 to remove the oxide layer on the metal skeleton and to introduce inert protective gas to prevent secondary oxidation of the metal surface after activation. The extrusion mechanism 9 is located inside the activation cylinder 6 and is used to apply radial elastic force to each slotted removal cylinder 10 so that it elastically fits against the outer surface of the metal frame. The base 1 is also equipped with a motor 3. The output axis of the motor 3 extends upward and is connected to the rotating disk 8 through the rotating disk 71 to provide rotational power for the entire processing system. The inside of the activation cylinder 6 forms a closed processing cavity. Each slotted removal cylinder 10 has an axially extending slotted cutting edge on its outer surface, which is used to contact the outer surface of the metal skeleton during rotation and remove the micro-oxide layer and adsorbed impurities formed on the metal skeleton during storage or pretreatment by mechanical scraping, so as to provide a clean and activated metal surface for subsequent rubber vulcanization bonding.

[0018] The rotary scraping mechanism 7 includes a mounting plate 76 disposed at the end of the rotating disk 8. A support rod 75 is disposed at the end of the mounting plate 76. An inert gas driving device 74 is disposed at one end of the support rod 75. A straight rod 73 is disposed at the end of the inert gas driving device 74.

[0019] A rotating disk 71 is provided at the end of the straight rod 73. One end of the rotating disk 71 is connected to the output end of the motor 3. The outer surface of the rotating disk 71 is provided with connecting rods 72 corresponding to multiple slotted removal cylinders 10. The ends of the multiple connecting rods 72 are all connected to the outer surface of the corresponding air cylinder 5. The other end of the gas cylinder 5 is connected to the inert gas driving device 74 through the mounting cylinder 78 and the hose 77. The protective gas generated by the inert gas driving device 74 enters the inner cavity of the gas cylinder 5 through the hose 77 and the mounting cylinder 78, and is then transported by the gas cylinder 5 to the inside of the slotted removal cylinder 10. Finally, it is evenly discharged from the slotted part of the slotted removal cylinder 10 into the activation cylinder 6 to form an inert atmosphere protective barrier.

[0020] The end of the connecting rod 72 connected to the air cylinder 5 is telescopic, which is used to buffer and limit the movement of the grooving removal cylinder 10 when the air cylinder 5 drives it to move. The end of the connecting rod 72 connected to the air cylinder 5 adopts a telescopic structure design and has a hydraulic damping structure inside. When the grooving removal cylinder 10 encounters a protrusion or irregular shape on the surface of the metal skeleton during the scraping process, the end of the connecting rod 72 can extend and retract slightly to absorb the impact displacement, play a limiting and buffering role, prevent the cylinder from shaking or the surface of the metal skeleton from being damaged due to rigid connection, and at the same time ensure that the relative position accuracy between each grooving removal cylinder 10 is not affected.

[0021] The end of the air cylinder 5 is connected to the slotting removal cylinder 10. The other end of the air cylinder 5 is provided with an installation cylinder 78. The end of the installation cylinder 78 is provided with a hose 77. The outer surface of the hose 77 is covered with a protective tube 714. The end of the protective tube 714 passes through the connecting rod 72 and is connected to the inert gas driving device 74. The end of the hose 77 is connected to the inside of the inert gas driving device 74.

[0022] The air cylinder 5 has an inner cylinder 79 that is movable inside. The end of the inner cylinder 79 is connected to the slotted removal cylinder 10. The end of the inner cylinder 79 is provided with multiple inclined rods 712. The end of the multiple inclined rods 712 is provided with a central disk 713. The end of the central disk 713 is provided with a shaft 711. The outer surface of the shaft 711 is provided with multiple blades 710. When the inert gas flows through the inner cavity of the cylinder 5, the airflow drives the blades 710 to rotate the shaft 711. The shaft 711 drives the inner cylinder 79 to rotate via the central disk 713 and the inclined rod 712, thereby driving the slotted removal cylinder 10 to rotate on its own axis while revolving around the center, so that the inert gas is evenly rotated and sprayed out from the slot.

[0023] The extrusion mechanism 9 includes a collar 94 fitted onto the outer surface of the air cylinder 5. A second side plate 96 is provided at one end of the mounting plate 76, and a spring 97 is provided on the side of the second side plate 96. A first side plate 95 is provided at the other end of the spring 97, and a push plate 92 is provided on the side of the first side plate 95. An arc-shaped groove 93 is formed on the side of the push plate 92, and the arc-shaped groove 93 slides in contact with the outer cylindrical surface of the collar 94. When the slotted removal cylinder 10 is subjected to a reverse thrust from the metal frame, the collar 94 drives the push plate 92 to compress the spring 97, resulting in elastic release.

[0024] The push plate 92 has an arc-shaped groove 93 on its side. The inner side of the arc-shaped groove 93 is movably disposed on the outer surface of the collar 94. The end of the rotating disk 8 has a sliding groove 91. The outer side of the grooving removal cylinder 10 is movably disposed on the inner side of the sliding groove 91. When the workpiece passes through, the spring 97 pushes the grooving removal cylinder 10 to reset and re-adhere to the surface of the metal skeleton with constant pressure, ensuring the uniformity and consistency of oxide layer removal.

[0025] Working principle: When using this device, the metal skeleton is first fed into the activation cylinder 6 through the feeding hopper 4. At this time, the motor 3 will drive the rotating disk 71 to rotate. The rotating disk 71 will drive the connecting rod 72 on the outer surface to rotate. The connecting rod 72 will drive the air cylinder 5 to rotate. The air cylinder 5 will drive the end slotted removal cylinder 10 and the rotating disk 8 to rotate, so as to scrape off the oxide layer on the outer surface of the metal skeleton inside the activation cylinder 6. Then, the inert gas driving device 74 will operate, venting internal gas into the hose 77, which then enters the mounting cylinder 78, and finally into the inner side of the gas cylinder 5. The gas is then delivered to the grooving removal cylinder 10 via the gas cylinder 5, and finally to the activation cylinder 6. Inside the gas cylinder 5, the grooving removal cylinder 10 rotates under the influence of the gas, causing the blades 710 to drive the internal shaft 711 to rotate. The shaft 711 drives the central disk 713 to rotate, which in turn drives the multiple inclined rods 712 on the outer surface to rotate. The inclined rods 712 drive the inner cylinder 79 to rotate. The inner cylinder 79 is connected to the grooving removal cylinder 10, thus driving the grooving removal cylinder 10 to rotate. This ensures that the inert gas is discharged as evenly as possible from the grooves of the grooving removal cylinder 10, guaranteeing a uniform coating on the outer surface of the metal frame and preventing metal debris and oxide layer fallout from entering the grooves of the grooving removal cylinder 10.

[0026] When the grooving removal cylinder 10 scrapes the outer surface of the metal skeleton, there will be metal skeletons of different shapes. At this time, there is a certain distance between the grooving removal cylinder 10 and the inner wall of the activation cylinder 6. When the grooving removal cylinder 10 directly and forcibly contacts the metal skeleton, it may cause deformation of the grooving removal cylinder 10 or the metal skeleton. Therefore, after the grooving removal cylinder 10 is squeezed, when the metal skeleton is not aligned, in order to avoid damage to the grooving removal cylinder 10 and the metal skeleton, the grooving removal cylinder 10 will slide inside the groove 91, thereby driving the collar 94 to be fixed. The collar 94 will drive the push plate 92 to be fixed. The push plate 92 will drive the side plate 95 set on the side to squeeze the spring 97. After completion, the grooving removal cylinder 10 will reset under the action of the spring 97.
