Description

Technical Field

[0001] This utility model belongs to the field of gasket processing technology, specifically relating to a composite gasket processing and molding equipment. Background Technology

[0002] Composite gaskets are high-performance sealing elements made by combining a metal skeleton layer and a flexible sealing layer through a hot-pressing process. Their core lies in achieving both mechanical strength and sealing performance through the synergistic effect of different materials.

[0003] Layer alignment is a core process in the manufacturing of composite gaskets. Misalignment between the metal skeleton and the sealing layer can lead to localized stress concentration, causing interfacial delamination or leakage at the sealing surface. In addition, the difference in the thermal expansion coefficients of dissimilar materials may exacerbate interlayer misalignment during hot pressing, further reducing sealing reliability. Therefore, to ensure the sealing performance and service life of composite gaskets, when they have a large number of layers or contain a large amount of flexible, thin-layer materials, a pre-compression process is used to improve the alignment of the material layers.

[0004] However, in the existing technology, when producing composite gaskets of various specifications, if it is necessary to pre-press the materials used in the composite gaskets to pre-fix each material layer or to make the materials between each layer initially interlock to form a mechanical interlocking structure, it is necessary to frequently change the corresponding size mold according to the specifications of different composite gaskets in order to ensure the alignment of the material layers during pre-pressing. Therefore, a composite gasket processing and forming equipment is proposed. Utility Model Content

[0032] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0033] like Figures 1-6 As shown, a composite sealing gasket processing and forming equipment includes a material transfer component 1 that can adjust the position of the gasket material within the equipment, a pre-compression component 2 that can meet the pre-compression requirements of gasket materials of various specifications, and a material placement component 3 that can place the gasket material below the pre-compression component 2.

[0034] In this embodiment: the material transfer assembly 1 includes a frame 101, a bearing seat 102 is fixedly connected to the lower part of the frame 101, a rotating shaft 103 is movably installed in the bearing seat 102, a turntable 104 is fixedly connected to the upper end of the rotating shaft 103, a motor 105 is fixedly installed in the rear of the frame 101, a first pulley 106 is fixedly connected to the output end of the motor 105, a second pulley 107 is fixedly connected to the lower end of the rotating shaft 103, and a belt 108 is provided between the first pulley 106 and the second pulley 107;

[0035] The frame 101 is rotatably connected to the turntable 104, the bearing seat 102 is rotatably connected to the rotating shaft 103, the first pulley 106 and the second pulley 107 are both toothed synchronous pulleys, and the belt 108 is a toothed synchronous belt.

[0036] The frame 101 provides mounting positions for components such as the bearing seat 102 and the column 201. The rotating shaft 103, whose movable range is limited by the bearing seat 102, is connected to the turntable 104, further limiting the movable range of the turntable 104 on the frame 101 and transmitting power to the turntable 104. The power from the motor 105 is transmitted to the rotating shaft 103 through the first pulley 106, the belt 108, and the second pulley 107.

[0037] In this embodiment: the pre-compression component 2 includes a limiting member that can fully align the gasket materials before being compressed, a pressure applying member that can initially combine the gasket materials, and a lifting member that can cause the limiting member to surround and align the gasket materials after the pressure applying member is running.

[0038] The lifting components include a lifting frame 203 mounted above the frame 101, and a limiting component including a ring frame 204 mounted below the lifting frame 203. Multiple transmission frames 205 are movably connected to the ring frame 204. A limiting plate 206 is fixedly connected to one end of each transmission frame 205 near the ring frame 204. A limiting rod 207 is provided between the ring frame 204 and the transmission frames 205. A second spring 208 is movably connected to the outer side of the limiting rod 207. A support rod 209 is fixedly installed inside the transmission frame 205. A slider 210 is provided between the transmission frame 205 and the support rod 209. A third spring 211 is provided between blocks 210. A connecting rod 212 is movably connected between the lifting frame 203 and the slider 210. The lifting component also includes columns 201 fixedly installed on both sides of the frame 101. A first spring 202 is movably connected to the outer side of the column 201. The lifting frame 203 is provided above the first spring 202. The pressure application component includes a bracket 213 fixedly installed on the frame 101. A hydraulic cylinder 214 is fixedly installed below the bracket 213. An extension rod 215 is fixedly connected below the lifting frame 203. An upper mold 216 is fixedly connected below the extension rod 215.

[0039] The first spring 202 and the lifting frame 203 are slidably connected to the column 201. The ring frame 204, the limiting rod 207, and the slider 210 are slidably connected to the transmission frame 205. The limiting rod 207 is slidably connected to the second spring 208. The slider 210 and the third spring 211 are slidably connected to the support rod 209. The lifting frame 203 and the slider 210 are rotatably connected to the connecting rod 212. The center lines of the ring frame 204, the extension rod 215, and the upper mold 216 coincide. The lower side of the ring frame 204 is integrally formed with multiple positioning grooves 217. The number of positioning grooves 217 is the same as the number of positioning blocks 305 on the same lower mold 304. The inner contour of the positioning groove 217 is the same as the outer contour of the part of the positioning block 305 located above the lower mold 304.

[0040] The first spring 202, whose movement direction is restricted by the column 201, causes the lifting frame 203, located between the two columns 201, to tend to move upward when not subjected to external force. The lifting frame 203 provides an installation position for components such as the extension rod 215 and drives the lifting of the limiting member composed of components such as the connecting rod 212. The ring frame 204, which can rise and fall with the lifting frame 203, contacts the lower mold 304, which can rotate with the turntable 104. This allows the limiting plate 206 to surround the pad material on the lower mold 304 when the ring frame 204 contacts and aligns with a certain lower mold 304. The transmission frame 205, which can slide relative to the ring frame 204, makes the distance from the limiting plate 206 to the center line of the ring frame 204 variable. The limiting rod 207 and the second spring... 208 restricts the movable range of the transmission frame 205 relative to the ring frame 204, and makes the transmission frame 205, which is not subjected to external force, tend to drive the limiting plate 206 to fit against the inner wall of the ring frame 204. The support rod 209 and the third spring 211 jointly restrict the movable range of the slider 210 within the transmission frame 205, and make the slider 210, which is not subjected to external force, tend to move away from the ring frame 204. The lifting frame 203 and the slider 210 are connected by the connecting rod 212. The hydraulic cylinder 214, which is mounted on the upper part of the lifting frame 203 by the bracket 213, can apply pressure to the lifting frame 203 during operation. The pressure transmitted by the hydraulic cylinder 214 to the lifting frame 203 is further transmitted downward through the extension rod 215 and the upper mold 216 set below the lifting frame 203.

[0041] In this embodiment: the material placement component 3 includes multiple positioning rings 301 fixedly installed on the turntable 104, a plug-in plate 302 is provided inside the positioning ring 301, multiple fourth springs 303 are provided between the inner side of the positioning ring 301 and the outer side of the plug-in plate 302, a lower mold 304 is movably connected to the plug-in plate 302, and multiple positioning blocks 305 are fixedly connected above the lower mold 304.

[0042] The insert plate 302 is slidably connected to the lower mold 304; the insert plate 302 is installed in the positioning ring 301 by the fourth spring 303, so that it can move together with the positioning ring 301 with the turntable 104, and can also move slightly inside the positioning ring 301. The insert plate 302 provides an installation position for the lower mold 304, which can place the gasket material. When the ring frame 204 descends, the positioning block 305, which can be inserted into the positioning groove 217, ensures that the ring frame 204 and the positioning block 305 can be aligned.

[0043] Working principle: When this equipment is installed and used for the processing and forming of composite sealing gaskets, before the gasket material is hot-pressed, the motor 105 and the hydraulic cylinder 214 can work intermittently to pre-press the materials belonging to the same composite sealing gasket.

[0044] Specifically, when the motor 105 works intermittently, it can drive the turntable 104 and the various material placement components 3 above it to rotate intermittently through the first pulley 106 and other components, so that each material placement component 3 passes under the ring frame 204 in sequence.

[0045] When the hydraulic cylinder 214 operates, it can press down the lifting frame 203, causing it to move the limiting component composed of the ring frame 204 and other parts to the lower mold 304 below the ring frame 204. When the ring frame 204 is lowered to the height that fits against the lower mold 304 and the positioning block 305 is inserted into the positioning groove 217, the lifting frame 203, which continues to move down, will translate the slider 210, which is pushed at the same height as the ring frame 204, through the connecting rod 212. Since the translation of the ring frame 204 is restricted by the positioning block 305, each connecting rod 212 can stably push the connected slider 210 to move towards the center of the ring frame 204. During the movement of the slider 210, the compressed third spring 211 will, while overcoming the elastic force of the second spring 208, smoothly push the transmission frame 205 and the limiting plate 206 towards the center of the ring frame 204, so that each limiting plate 206 clamps the pad material placed on the lower mold 304 from multiple directions. After the limit plate 206 contacts the pad material and can no longer move, if the lifting frame 203 continues to move downward, the slider 210 can only continue to compress the second spring 208.

[0046] Conversely, when the lifting frame 203 rises, if the lower mold 304 contacts the ring frame 204, then under the action of the second spring 208 and the third spring 211, the ring frame 204 will only rise with the lifting frame 203 when the limiting plate 206 is in contact with the inner side of the ring frame 204 and the side of the slider 210 away from the third spring 211 is in contact with the transmission frame 205.

[0047] Therefore, by adjusting the single-run duration and interval of the motor 105 and hydraulic cylinder 214, the turntable 104 can drive each material placement component 3 to pass and stop sequentially under the ring frame 204 when the hydraulic cylinder 214 is paused. Conversely, when the hydraulic cylinder 214 is running, the motor 105 is paused. Furthermore, by selecting an extension rod 215 of appropriate length and an upper mold 216 of appropriate diameter, the limiting plate 206 can be made to contact and clamp the limiting gasket material first during the pre-pressing process of the upper mold 216 on the lower mold 304, thus fully aligning the multiple layers of material belonging to the same gasket. After the pre-pressing is completed, the limiting plate 206 can continue to clamp all the gasket material for a certain period of time while gradually reducing the force, to prevent the gasket material from sticking to the upper mold 216.

[0048] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
