Detailed implementation manners

[0037] The core of the present invention is to provide a vulcanization workbench for a composite jacket lightning arrester to improve the vulcanization efficiency of the composite jacket lightning arrester, reduce the labor cost, and improve the utilization efficiency of the automation equipment;

[0038] Another core of the present invention is to provide a composite jacket lightning arrester vulcanization system having the above-mentioned vulcanization workbench for a composite jacket lightning arrester, and a composite jacket lightning arrester vulcanization process using the composite jacket lightning arrester vulcanization system.

[0039] Hereinafter, the embodiments will be described with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the content of the invention described in the claims in any way. In addition, all the contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the invention described in the claims.

[0040] An embodiment of the present invention discloses a vulcanization workbench for a composite outer sheath lightning arrester, which is used for vulcanizing a lightning arrester core body and includes a frame, a rotating workbench and a vulcanization mold.

[0041] Among them, those skilled in the art can understand that the lightning arrester core body is a common lightning arrester core body in the prior art, which is assembled by resistor chips, gaskets, upper and lower electrodes, insulating cylinders, and bolts. The specific structure of the lightning arrester core body will not be elaborated herein. The vulcanization workbench for a composite outer sheath lightning arrester disclosed in the embodiment of the present invention is used for vulcanizing the assembled lightning arrester core body to form an outer insulation umbrella sleeve 401 on the outer layer of the lightning arrester core body, as Figure 1 shown.

[0042] Among them, the frame plays a supporting role and is used to support the vulcanization workbench for a composite outer sheath lightning arrester. Those skilled in the art can understand that the frame only needs to ensure a stable supporting effect, and the specific structure and material are not limited herein.

[0043] As Figures 2 - 3 shown, the rotating workbench is rotatably arranged on the frame and includes a rotating lower seat 101 and a rotating upper seat 102 arranged on the upper part of the rotating lower seat 101. The rotating lower seat 101 and the rotating upper seat 102 cooperate, that is, the rotating lower seat 101 and the rotating upper seat 102 can be buckled or separated. Four working stations are formed at intervals around the rotating workbench. The four working stations are respectively a loading and unloading station 301, a silicone rubber injection station 302, a first mold clamping and heating station 303, and a second mold clamping and heating station 304. The four working stations are evenly arranged around the rotating workbench, that is, every time the rotating workbench rotates 90°, the corresponding mold is transferred to the next working station. And the loading and unloading station 301, the silicone rubber injection station 302, the first mold clamping and heating station 303, and the second mold clamping and heating station 304 are arranged in sequence clockwise or counterclockwise.

[0044] In the following, the case where the loading and unloading station 301, the silicone rubber injection station 302, the first mold clamping and heating station 303, and the second mold clamping and heating station 304 are arranged in the clockwise direction will be taken as an example for description. Among them, the loading and unloading station 301 is used to take out the finished lightning arrester and load the lightning arrester core body; the silicone rubber injection station 302 is used to inject vulcanized silicone rubber; the first mold clamping and heating station 303 and the second mold clamping and heating station 304 are used to heat the vulcanized silicone rubber. During the rotation of the rotating workbench, the mold set on it is sequentially conveyed in the order of the loading and unloading station 301, the silicone rubber injection station 302, the first mold clamping and heating station 303, and the second mold clamping and heating station 304 to complete the corresponding technological processes at the corresponding working stations.

[0045] As Figures 4 - 5As shown in the figure, there are four sets of vulcanization molds, which are evenly arranged on the rotary table along the rotation center of the rotary table. That is, the four sets of vulcanization molds can rotate synchronously with the rotary table. During the rotation of the four sets of vulcanization molds, they are sequentially switched among four stations. That is, during the rotation of the vulcanization molds, if the first vulcanization mold sequentially passes through the loading and unloading station 301, the silicone rubber injection station 302, the first mold clamping and heating station 303, and the second mold clamping and heating station 304 to complete a cycle process, then the second vulcanization mold downstream of the first vulcanization mold sequentially passes through the second mold clamping and heating station 304, the loading and unloading station 301, the silicone rubber injection station 302, and the first mold clamping and heating station 303. The same applies to the other two vulcanization molds and will not be elaborated here. The difference between any two adjacent ones of the four sets of vulcanization molds is one station. That is, as the rotary table rotates once, the four sets of molds respectively perform the operations of loading and unloading, silicone rubber injection, first mold clamping and heating, and second mold clamping and heating. When the rotary table rotates four times, the four sets of molds respectively complete the production of a finished lightning arrester.

[0046] The vulcanization mold includes the lower mold 201 of the vulcanization mold and the upper mold 202 of the vulcanization mold. The lower mold 201 of the vulcanization mold is arranged on the rotary lower seat 101, and the upper mold 202 of the vulcanization mold is arranged on the rotary upper seat 102. The lower mold 201 and the upper mold 202 of the vulcanization mold are buckled together to form a complete vulcanization mold. Those skilled in the art can understand that the specific connection manner between the lower mold 201 and the upper mold 202 of the vulcanization mold is a common connection manner and will not be elaborated here.

[0047] The composite jacket lightning arrester vulcanization workbench provided by the present invention has a rotary table rotatably arranged on the frame. The rotary table includes a rotary lower seat 101 and a rotary upper seat 102. The lower mold 201 of the vulcanization mold is arranged on the rotary lower seat 101, and the upper mold 202 of the vulcanization mold is arranged on the rotary upper seat 102. The four directions of the rotary table are four stations, which are sequentially the loading and unloading station 301, the silicone rubber injection station 302, the first mold clamping and heating station 303, and the second mold clamping and heating station 304. Four sets of vulcanization molds are evenly arranged along the rotation center of the rotary table to drive each vulcanization mold to switch among the four stations. The composite jacket lightning arrester vulcanization workbench provided by the present invention enables the vulcanization process of the composite jacket lightning arrester to be concentrated on one workbench, realizes the integrated manufacturing of the composite jacket lightning arrester vulcanization, can achieve the continuity of the composite jacket lightning arrester vulcanization process, and can also realize the simultaneous vulcanization of multiple lightning arresters, solving the problems of single-mold vulcanization equipment and single-station intermittent vulcanization in the prior art.

[0048] In order to facilitate the mold closing and mold opening processes of the vulcanization mold, that is, the opening and closing of the vulcanization mold, in a specific embodiment of the present invention, such as Figure 2As shown, the upper mold 202 of the vulcanization mold is set on the rotating upper seat 102 through a lifting slider, and the lifting slider is driven by a lifting drive device to slide up and down to complete mold closing and mold opening. The arrangement of the lifting slider and the lifting drive device makes the mold closing and mold opening process of the vulcanization mold simple and convenient. It will be understood by those skilled in the art that there are many types of lifting drive devices, such as linear motors, cylinders, etc. As long as it can drive the lifting slider to slide up and down, thereby driving the upper mold 202 of the vulcanization mold to slide up and down on the rotating upper seat 102 to achieve mold closing and mold opening, the specific type of lifting drive device can be selected by those skilled in the art according to actual conditions.

[0049] To improve vulcanization efficiency, the present invention provides a vulcanization mold with multiple vulcanization cavities. This means that a single vulcanization mold can accommodate multiple arrester cores and vulcanize them simultaneously. Specifically, the cavities within the vulcanization mold can be arranged in a rectangular array or other configurations.

[0050] like Figure 2 As shown, in a specific embodiment of the present invention, the curing mold has eight curing cavities. This means that one curing mold can simultaneously accommodate eight arrester cores, arranged in a rectangular array. Specifically, the rectangular array is a 4×2 array. Of course, the rectangular array can be arranged in other ways, and those skilled in the art can configure it based on actual needs. This rectangular array arrangement reduces the overall size of the curing mold, saving space and improving production efficiency.

[0051] In order to realize online monitoring and data tracking and recording during the vulcanization process of the arrester core, in a specific embodiment of the present invention, the vulcanization mold is provided with a thermocouple for detecting temperature and a pressure sensor for detecting pressure. The thermocouple can measure the temperature inside the vulcanization mold and perform temperature measurement on the vulcanization molds at different stations, thereby realizing temperature monitoring; the pressure sensor can measure the pressure inside the vulcanization mold and perform pressure measurement on the vulcanization molds at different stations, thereby realizing pressure monitoring. The provision of thermocouples and pressure sensors realizes online monitoring of the production and vulcanization of the arrester core and full tracking of production and vulcanization information, thereby improving the uniformity and reliability of the arrester products. Thermocouples are commonly used temperature measuring elements, and pressure sensors are commonly used sensors for measuring pressure. Their specific temperature measurement principles and pressure measurement principles will not be repeated in this article.

[0052] The embodiment of the invention discloses a composite jacket arrester vulcanization system, which comprises a composite jacket arrester vulcanization workbench and an injection machine.

[0053] Among them, the vulcanization workbench for composite jacket arresters is the vulcanization workbench for composite jacket arresters provided in the above embodiment. The injection machine is arranged at the silicone rubber injection station 302 and is used to inject and vulcanize the arrester core body in the vulcanization mold at the silicone rubber injection station. The injection machine is a commonly used injection instrument in the prior art, and its injection principle and structure will not be elaborated here.

[0054] In a specific embodiment of the present invention, the heating temperatures of the vulcanization molds at the first mold clamping and heating station 303 and the second mold clamping and heating station 304 are the same or different. That is, the heating temperature can be set to the same temperature. The settings of the first mold clamping and heating station 303 and the second mold clamping and heating station 304 are only to meet the requirements of the heating time; the heating temperature can also be set to different temperatures. The different heating temperatures set for the first mold clamping and heating station 303 and the second mold clamping and heating station 304 meet the vulcanization requirements of the corresponding arresters. For the specific temperature setting, those skilled in the art can make corresponding settings according to the specific vulcanization process of the arrester core body.

[0055] The embodiment of the present invention discloses a vulcanization process for composite jacket arresters, which uses the composite jacket arrester vulcanization system provided in the above embodiment to vulcanize the arrester core body, including the steps:

[0056] Loading and unloading the arrester core body; since there is no finished arrester product in the vulcanization mold at the loading and unloading station when the composite jacket arrester vulcanization system is first used, the arrester core body can be loaded into the vulcanization mold at the loading and unloading station. After the composite jacket arrester vulcanization system goes through successive cycles, there is a vulcanized and formed finished arrester product in the vulcanization mold at the unloading station. At this time, it is necessary to first take out the vulcanized finished arrester product in the vulcanization mold at the loading and unloading station, and then load the arrester core body to be vulcanized into the vulcanization mold at the loading and unloading station.

[0057] When the composite jacket arrester vulcanization system is first used, that is, when there is no finished arrester product in the vulcanization mold at the loading and unloading station, the vulcanization mold at the loading and unloading station first opens the mold, the arrester core body is loaded, and then the vulcanization mold at the loading and unloading station closes the mold to complete the loading step. After the composite jacket arrester vulcanization system operates, this step successively includes unloading and loading, that is, first taking out the vulcanized finished arrester product in the vulcanization mold at the loading and unloading station, and then loading the arrester core body into the vulcanization mold at the loading and unloading station. Specifically, the vulcanization mold at the loading and unloading station first opens the mold, the finished arrester product is taken out, then the arrester core body is loaded, and then the vulcanization mold at the loading and unloading station closes the mold to complete the unloading and loading steps.

[0058] To facilitate the description of the steps of the vulcanization process of the composite jacket lightning arrester, hereinafter, when the vulcanization system of the composite jacket lightning arrester starts to work, the vulcanization mold at the loading and unloading station is the first vulcanization mold, the vulcanization mold at the silicone rubber injection station is the second vulcanization mold, the vulcanization mold at the first mold clamping and heating station is the third vulcanization mold, and the vulcanization mold at the second mold clamping and heating station is the fourth vulcanization mold for illustration.

[0059] Injection vulcanization;

[0060] After the lightning arrester core is loaded onto the first vulcanization mold, the four sets of vulcanization molds rotate clockwise along the rotation center of the rotary table. At this time, the first vulcanization mold rotates to the silicone rubber injection station 302, the second vulcanization mold rotates to the first mold clamping and heating station 303, the third vulcanization mold rotates to the second mold clamping and heating station 304, and the fourth vulcanization mold rotates to the loading and unloading station 301. The injection machine injects vulcanized silicone rubber into the first vulcanization mold to complete the injection vulcanization step. The lightning arrester core is loaded at the loading and unloading station 301 and loaded onto the fourth vulcanization mold.

[0061] Mold clamping and heating;

[0062] After the injection vulcanization step of the lightning arrester core in the first vulcanization mold is completed, the four sets of vulcanization molds continue to rotate clockwise along the rotation center of the rotary table. The first vulcanization mold rotates to the first mold clamping and heating station 303, the second vulcanization mold rotates to the second mold clamping and heating station 304, the third vulcanization mold rotates to the loading and unloading station 301, and the fourth vulcanization mold rotates to the silicone rubber injection station 302. The first vulcanization mold conducts the first heating on the vulcanized silicone rubber inside the vulcanization mold. The injection machine injects vulcanized silicone rubber into the fourth vulcanization mold. The loading and unloading station 301 loads the lightning arrester core and loads it onto the third vulcanization mold.

[0063] After the first mold clamping and heating step of the lightning arrester core in the first vulcanization mold is completed, the four sets of vulcanization molds continue to rotate clockwise along the rotation center of the rotary table. The first vulcanization mold rotates to the second mold clamping and heating station 304, the second vulcanization mold rotates to the loading and unloading station 301, the third vulcanization mold rotates to the silicone rubber injection station 302, and the fourth vulcanization mold rotates to the first mold clamping and heating station 303. The first vulcanization mold conducts the second heating on the vulcanized silicone rubber inside the vulcanization mold. The loading and unloading station 301 loads the lightning arrester core and loads it onto the second vulcanization mold. The injection machine injects vulcanized silicone rubber into the third vulcanization mold. The fourth vulcanization mold conducts the first heating on the vulcanized silicone rubber inside the vulcanization mold. At this time, there are lightning arrester cores in the first vulcanization mold, the second vulcanization mold, the third vulcanization mold, and the fourth vulcanization mold.

[0064] After the second mold clamping and heating step of the arrester core in the first vulcanization mold is completed, the vulcanization process of the arrester core in the first vulcanization mold is completed, and the finished arrester product after vulcanization is obtained. The four vulcanization molds continue to rotate clockwise along the rotation center of the rotary table. The first vulcanization mold rotates to the loading and unloading station 301, the second vulcanization mold rotates to the silicone rubber injection station 302, the third vulcanization mold rotates to the first mold clamping and heating station 303, and the fourth vulcanization mold rotates to the second mold clamping and heating station 304. The finished arrester product in the first vulcanization mold is taken out at the loading and unloading station 301, and then the arrester core is loaded into the first vulcanization mold; the injection machine injects vulcanized silicone rubber into the second vulcanization mold, the third vulcanization mold heats the vulcanized silicone rubber inside the vulcanization mold for the first time, and the fourth vulcanization mold heats the vulcanized silicone rubber inside the vulcanization mold for the second time. At this step, the vulcanization process of the arrester core in the first vulcanization mold is completed, and the finished arrester product is taken out. As the four molds continue to rotate clockwise along the rotation center of the rotary table, the steps of loading the arrester core from the mold at the loading and unloading station 301, rotating to the silicone rubber injection station 302 for injection vulcanization, rotating to the first mold clamping and heating station 303 for the first heating, rotating to the second mold clamping and heating station 304 for the second heating, and rotating to the loading and unloading station 301 to take out the finished arrester product are cycled on the composite outer sheath arrester vulcanization system.

[0065] It should be noted that the vulcanization mold itself has a heating function, and it heats and keeps warm the arrester core inside or the arrester after injecting vulcanized silicone rubber at all four stations, not only heating and keeping warm the arrester after injecting vulcanized silicone rubber at the first mold clamping and heating station 303 and the second mold clamping and heating station 304. Since the main work of the first mold clamping and heating station 303 and the second mold clamping and heating station 304 is heating and keeping warm, the main work of the loading and unloading station 301 is loading and unloading, and the main work of the silicone rubber injection station 302 is injecting silicone rubber, so when introducing the solution, for the convenience of understanding, the heating functions of the first mold clamping and heating station 303 and the second mold clamping and heating station 304 are mainly introduced.

[0066] The composite outer sheath arrester vulcanization process provided by the present invention realizes the continuity of the vulcanization treatment process of the arrester core, and can also vulcanize multiple arrester cores simultaneously, without vulcanizing multiple arrester cores sequentially, improving the production efficiency and reducing the labor cost.

[0067] In order to ensure the continuity of the vulcanization process of the arrester core, on the basis of the above embodiments, the feeding and discharging steps, injection vulcanization step, and mold clamping and heating steps of the arrester core are carried out simultaneously. That is, while the first vulcanization mold completes the discharging of the finished arrester and the feeding of the arrester core, the second vulcanization mold completes the injection vulcanization step, the third vulcanization mold completes the first mold clamping and heating process, and the fourth vulcanization mold completes the second mold clamping and heating process, ensuring the continuity of the vulcanization process of the arrester core.

[0068] In order to further reduce labor costs and improve production efficiency, in a specific embodiment of the present invention, in the feeding and discharging steps of the arrester core, a robot is used to feed the arrester core into the vulcanization mold at the feeding and discharging station, and a robot is used to take out the finished arrester after vulcanization in the vulcanization mold at the feeding and discharging station. Through the operation of the robot, labor costs are reduced, production efficiency is improved, and at the same time, the automation of the vulcanization process of the composite outer sheath arrester is realized.
