DETAILED DESCRIPTION

[0032] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0033] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0034] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0035] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0036] Those skilled in the art should know that, taking a vulcanizer as an example, when designing the cooling of a conventional hydraulic system, the cooling power is generally designed according to the full load condition of the vulcanizer; that is, the vulcanizer is designed to be cooled when it is operating at maximum power and the ambient temperature is at the highest temperature. However, the temperature generated by the vulcanizer in different working conditions is different, and the working condition of the vulcanizer will be affected by factors such as the working condition, the vulcanization steps, the amount of the product to be vulcanized, and the environment.

[0037] Specifically, when the vulcanizer is started, the return oil temperature of the hydraulic system begins to rise gradually until it is in a relatively stable range. If the hydraulic system is always in the maximum cooling state during this process, it will cause a large waste of resources in the early stage.

[0038] The working power of the vulcanizer is mainly determined by the amount of products to be vulcanized. The greater the amount of products to be vulcanized, the greater the working power of the vulcanizer and the higher the temperature generated, and vice versa. If the hydraulic system is always in the maximum cooling state, it will cause a waste of resources with a small amount of products.

[0039] The cooling of hydraulic system is generally carried out by water circulation, and the temperature of cooling water in the water circulation corresponds to the external environment temperature. In summer, when the temperature is high, the temperature of cooling water in the water circulation may be 20℃~25℃, while in winter, the temperature of cooling water in the water circulation may be below 10℃, and there will be a temperature difference of more than ten degrees Celsius between the two; and the ambient temperature generated by the vulcanizer itself will also be affected by the environment, making the return oil temperature in summer higher than that in winter. If the hydraulic system is always in the maximum cooling state, it will cause a large waste of resources in non-winter.

[0040] Based on the above analysis results, the present application can control and adjust the cooling power of the hydraulic system according to the working state of the vulcanizer. Compared with the traditional full-power cooling method, it can effectively reduce energy loss and save costs.

[0041] In order to solve the above technical problems, the present application provides a cooling circulation pipeline structure of a cooling device, such as Figure 2As shown, one preferred embodiment includes a housing 21, a plurality of cooling components 22, at least one pair of water pipes 24 and at least one driving device 2. The housing 21 is used to support the entire cooling device, and the housing 21 can be installed on the upper end surface of the oil tank 100. The cooling component 22 is installed on the housing 21, and the cooling component 22 can extend into the oil tank 100 to cool the oil. By setting up a plurality of cooling components 22, it is possible to achieve synchronous cooling of various areas in the oil tank 100, thereby ensuring the stability of the oil outlet temperature of the oil tank 100. The water pipe 24 can be movably installed on the housing 21 and connected to the cooling component 22 to circulate water to cool the oil in the oil tank 100. The driving device 25 is installed on the housing 21 and is drivingly connected to the corresponding water pipe 24. The driving device 25 can drive the water pipe 24 to perform corresponding actions according to the power set by the cooling device, thereby cutting off the water circulation of some cooling components 22.

[0042] It should be known that the cooling power of the cooling device for the oil in the oil tank 100 is equivalent to the sum of the cooling powers of each cooling assembly 22; thus, the cooling power of the cooling device can be controlled by controlling the number of working cooling assemblies 22. In order to ensure stable cooling of the oil in the oil tank 100, the cooling assemblies 22 need to be evenly arranged; this ensures that the cooling assemblies 22 cool down the oil in each area of ​​the oil tank 100 at the same time, thereby ensuring that the oil temperature in each area of ​​the oil tank 100 tends to be consistent, so as to ensure the temperature of the oil outlet temperature, and avoid or reduce the error of the temperature difference compensation calculation of the hydraulic system.

[0043] In this embodiment, there are many specific structures of the cooling device 2 that can achieve the above functions. For the sake of easy understanding, one of the structures will be described in detail below. Figure 2 As shown, the cooling device 2 includes a housing 21, a plurality of cooling components 22, at least one sealing component 24 and at least one pipeline regulating component 25. The housing 21 is used to support the entire cooling device 2, and the housing 21 can be installed on the upper end surface of the oil tank 100. The cooling component 22 is installed on the housing 21, and the cooling component 22 can extend into the oil tank 100 to cool the oil. Through the arrangement of multiple cooling components 22, it is possible to achieve synchronous cooling of various areas in the oil tank 100, thereby ensuring the stability of the oil outlet temperature of the oil tank 100. The sealing component 24 is installed on the housing 21, and the sealing component 24 can drive the cooling components 22 at the corresponding position to seal with the housing 21, thereby forming a cooling cavity connected to the oil circuit network to meet the oil cooling requirements of specific actuators. The pipeline regulating component 25 can be connected to each cooling component 22 for water circulation, and the pipeline regulating component 25 can cut off the water circulation of some cooling components 22 according to the set cooling power.

[0044] It should be known that the cooling power of the cooling device 2 for the oil in the oil tank 100 is equivalent to the sum of the cooling powers of the cooling components 22; thus, the cooling power of the cooling device 2 can be controlled by controlling the number of cooling components 22 in operation. In order to ensure stable cooling of the oil in the oil tank 100, the cooling components 22 need to be evenly arranged; this ensures that the cooling components 22 cool down the oil in each area of ​​the oil tank 100 at the same time, thereby ensuring that the oil temperature in each area of ​​the oil tank 100 tends to be consistent, so as to ensure the stability of the oil outlet temperature and avoid or reduce the error in the temperature difference compensation calculation of the hydraulic system.

[0045] In this embodiment, the oil tank 100 of the hydraulic system generally adopts a barrel-shaped structure or a rectangular structure; in order to give full play to the cooling efficiency of the cooling component 22, such as Figure 1 As shown, in this embodiment, a rectangular structure is preferably used for the oil tank 100. The rectangular structure of the oil tank 100 can be divided into multiple equal volume areas in a horizontal and vertical manner, and multiple cooling components 22 can correspond to each divided area, thereby ensuring that the cooling components 22 cool the oil in the oil tank 100 uniformly. At this time, the arrangement of the multiple cooling components 22 is an array arrangement.

[0046] It is understandable that the cooling assembly 22 can radiate to adjacent areas when performing cooling work, so there are cooling redundant positions in the areas divided by the oil tank 100. In layman's terms, the oil in the cooling redundant position will be cooled to a certain extent by the cooling radiation of the cooling assembly 22 in multiple adjacent areas, so the cooling efficiency requirements for the corresponding cooling assembly 22 are relatively low. Specifically, at least three other cooling assemblies 22 are arranged around the cooling assembly 22 located at the cooling redundant position. Based on the characteristics of the above-mentioned cooling redundant position, cutting off the cooling assembly 22 at the cooling redundant position will not have a significant impact on the overall cooling level of the oil in the oil tank 100.

[0047] It should be noted that the cooling power of the cooling device can be regarded as the water supply per unit time, and the cooling efficiency of the cooling device can be regarded as the cooling temperature of the oil in the oil tank 100 per unit time. The cooling efficiency and cooling power of the cooling device are not necessarily the same, that is, if the water supply of the cooling device is reduced by 50%, it does not mean that the cooling efficiency of the cooling device for the oil in the oil tank 100 is reduced by 50%.

[0048] In this embodiment, the cooling assembly 22 that is cut off when the gear position of the cooling device is adjusted can be any. However, in actual applications, people in this field hope to improve the cooling efficiency of the cooling device as much as possible while reducing the cooling power of the cooling device. Therefore, in this embodiment, the cooling assembly 22 that is cut off when the cooling power of the cooling device is adjusted is preferably a cooling assembly 22 located at a cooling redundant position.

[0049] More specifically, since only two surfaces of the corner position of the oil tank 100 can be connected to the rest of the area according to the divided area, that is, the fluidity of the oil at the corner position is average, the corner position of the oil tank 100 can also be used as a characteristic with a certain cooling redundancy. Therefore, the cooling assembly 22 located at the corner position of the array can also be cut off by the pipeline adjustment assembly 25 to achieve the cooling power adjustment of the cooling device.

[0050] In this embodiment, Figures 5 to 12 As shown, the plurality of cooling components 22 are arranged in m rows and n columns, and the values ​​of m and n are both odd numbers. The cooling components 22 that are blocked by the pipeline regulating components 25 are symmetrically arranged along the middle rows and middle columns of the array.

[0051] It should be known that, in order to ensure the cooling efficiency of the cooling components 22 on the oil in the oil tank 100, the cut-off cooling components 22 are preferably distributed symmetrically, and the cut-off cooling components 22 are preferably arranged at intervals, so that the remaining cooling components 22 in working state can basically achieve uniform cooling of the oil in the oil tank 100. Therefore, in order to facilitate the symmetrical arrangement of the cut-off cooling components 22, the multiple cooling components 22 included in the cooling device in this embodiment preferably use odd rows and odd columns, and then the middle row and middle column can be used as the symmetry axis.

[0052] In this embodiment, Figures 5 to 12 As shown, when adjusting the power of the cooling device, the driving device 25 can drive the water pipe 24 to cut off the water circulation of different numbers of cooling components 22 in the selected area, so that the cooling power of the cooling device can be adjusted in multiple gears between 50% and 100%, that is, at most nearly half of the cooling components 22 can be cut off. However, according to the characteristics of the cooling redundancy position, the cooling efficiency of the cooling device can be guaranteed to be greater than 50%, or even greater than 70%.

[0053] For ease of understanding, the following will provide a detailed description using specific examples. Figures 5 to 12 As shown, taking m=3, n=5 and a total of fifteen cooling components 22 as an example, the cooling power of the cooling device can be divided into eight gears from 50% to 100%, that is, corresponding to eight combination modes. Each combination mode will be described in detail below in conjunction with the accompanying drawings. It should be noted that in Figures 5 to 12 In the figure, each cooling component 22 is represented by a circle, the cut-off cooling component 22 is bolded and marked with ×, and the position of each cooling component 22 is represented by the coordinates (i, j) of the corresponding m×n array, then the value of i is {1, 2, 3}, and the value of j is {1, 2, 3, 4, 5}.

[0054] Combination mode 1: Figure 5As shown, all fifteen cooling assemblies 22 are in working state, and the cooling power of the cooling device is 100%.

[0055] Combination mode 2: Figure 6 As shown, one cooling assembly 22 among the fifteen cooling assemblies 22 is cut off, and the coordinate position of the cut off cooling assembly 22 is (i=2, j=3); at this time, the cooling power of the cooling device is 14 / 15, which is about 93%.

[0056] Combination mode three: Figure 7 As shown, two cooling components 22 among the fifteen cooling components 22 are cut off, and the coordinate positions of the cut off cooling components 22 are (i=2, j=2) and (i=2, j=4) respectively; at this time, the cooling power of the cooling device is 13 / 15, which is about 87%.

[0057] Combination mode 4: Figure 8 As shown, three cooling components 22 among the fifteen cooling components 22 are cut off, and the coordinate positions of the cut off cooling components 22 are (i=2, j=1), (i=2, j=3) and (i=2, j=5) respectively; at this time, the cooling power of the cooling device is 12 / 15, that is, 80%.

[0058] Combination mode 5: Fig. 9 As shown, four cooling components 22 among the fifteen cooling components 22 are cut off, and the coordinate positions of the cut-off cooling components 22 are (i=1, j=2), (i=1, j=4), (i=3, j=2) and (i=3, j=4), respectively; at this time, the cooling power of the cooling device is 11 / 15, which is about 73%.

[0059] Combination mode six: Fig.10 As shown, five cooling components 22 out of fifteen cooling components 22 are cut off, and the coordinate positions of the cut-off cooling components 22 are (i=1, j=2), (i=1, j=4), (i=2, j=3), (i=3, j=2) and (i=3, j=4); at this time, the cooling power of the cooling device is 10 / 15, which is about 67%.

[0060] Combination mode seven: Fig.11 As shown, six cooling components 22 out of fifteen cooling components 22 are cut off, and the coordinate positions of the cut-off cooling components 22 are (i=1, j=2), (i=1, j=4), (i=2, j=2), (i=2, j=4), (i=3, j=2) and (i=3, j=4); at this time, the cooling power of the cooling device is 9 / 15, that is, 60%.

[0061] Combination mode eight: Fig.12As shown, eight cooling components 22 out of fifteen cooling components 22 are cut off, and the coordinate positions of the cut-off cooling components 22 are (i=1, j=1), (i=1, j=3), (i=1, j=5), (i=2, j=2), (i=2, j=4), (i=3, j=1), (i=3, j=3) and (i=3, j=5); at this time, the cooling power of the cooling device is 7 / 15, which is about 47%.

[0062] In this embodiment, Figure 1 As shown, there are multiple pairs of water pipes 24, and each pair of two water pipes 24 corresponds to a driving device 25. There are multiple specific ways for the driving device 25 to cut off the cooling component 22 by driving the water pipe 24; for example, the driving device 25 can drive the water pipe 24 to rotate in a circle to achieve the cutoff of the cooling component 22, and for example, the driving device 25 can drive the water pipe 24 to move axially to achieve the cutoff of the cooling component 22. For the convenience of understanding, the following will be described in detail by taking the driving device 25 driving the water pipe 24 to rotate in a circle as an example. The driving device 25 can synchronously drive the corresponding two water pipes 24 to rotate, thereby cutting off the water circulation of the corresponding cooling component 22; multiple pairs of water pipes 24 can adjust different gears of cooling power through different rotation angles.

[0063] Specifically, Figure 1 and Figure 4 As shown, the water pipe 24 is rotatably mounted on the housing 21 and communicated with the interface 210 provided on one side of the housing 21. In each pair of two water pipes 24, the cooling water in the external water tank (not shown) can be passed into the corresponding water pipe 24 through the interface 210 until it flows to the corresponding cooling assembly 22; at the same time, the warm water that absorbs heat in the cooling assembly 22 can flow from the other water pipe 24 along the interface 210 to the recovery tank (not shown). There are many transmission structures for the drive device 25 to drive the two water pipes 24 to rotate synchronously, and the common ones are belt drive, chain drive and gear drive. For the convenience of understanding, a specific example will be used for detailed description below. The output end of the drive device 25 is equipped with a main gear 251, and the same side ends of the two water pipes 24 are both equipped with a sub-gear 241. The main gear 251 and the sub-gear 241 are connected by a toothed synchronous belt 26, and then the drive device 25 drives the two water pipes 24 to rotate in the same direction at the same time by driving the rotation of the main gear 251. The synchronous belt 26 has the advantages of high transmission accuracy and low transmission noise.

[0064] It should be known that the specific structure and working principle of the driving device 25 are well-known technologies to those skilled in the art, so they will not be elaborated in detail here; common driving devices 25 include motors, rotary cylinders, and rotary hydraulic cylinders, etc., and motors are preferably used in this embodiment.

[0065] In this embodiment, Figures 1 to 3 As shown, the cooling assembly 22 includes a cooling pipe 221, a pair of hoses 222 and a connecting seat 224. When installing the cooling assembly 22, the cooling assembly 22 can be supported and installed on the lower end surface of the shell 21 through the connecting seat 224. The cooling pipe 221 can be a metal pipe, such as a copper pipe; it can also be a non-metallic pipe, such as a glass pipe or a plastic pipe; the cooling pipe 221 has a certain rigidity and is spirally arranged to provide a larger contact area to accelerate cooling; the cooling pipe 221 can be extended into the oil tank 100 as a cooling section of the cooling assembly 22. The cooling pipe 221 is generally formed by winding a whole pipe. The two ends of the cooling pipe 221 can be connected to the lower end of the corresponding hose 222. The hose 222 can be connected or cut off with the corresponding water pipe 24 through the upper end, thereby realizing the conduction or cutoff of the cooling assembly 22.

[0066] In this embodiment, there are many specific structures of the water pipe 24 that can cut off the cooling assembly 22. For ease of understanding, one of the structures will be described in detail below. Figure 4 , Figures 13 to 15 As shown, the number of pairs of water pipes 24 takes the minimum value of m and n; multiple pairs of water pipes 24 are equidistantly distributed along the row or column direction. The water pipes 24 are connected to the cooling components 22 of the corresponding rows or columns for water inlet and drainage through multiple connection areas arranged at intervals along the axial direction. The upper end of each hose 222 in the cooling component 22 is connected with a connector 223, and the connector 223 is connected to the hose 222 through a through hole 2231. The connector 223 can be stably positioned and installed on the shell 21 and sleeved with the corresponding water pipe 24. Each connection area of ​​the water pipe 24 is arranged at intervals along the circumferential direction with at least one water receiving hole 240, and the water pipe 24 can be connected to the through hole 2231 set in the connector 223 through the water receiving hole 240, or the water pipe 24 cuts off the through hole 2231 of the connector 223 through the pipe wall at the non-water receiving hole position. The number and circumferential position of the water receiving holes 240 corresponding to each connection area are not all the same. The water pipe 24 is driven to rotate by the driving device 25; different driving devices 25 rotate the corresponding water pipe 24 at a set angle, thereby performing different amounts of cutoffs on the cooling components 22 at the cooling redundant position and the array corner position.

[0067] It should be known that when the water pipe 24 rotates, the connector 223 and the interface 210 remain stationary relative to the housing 21 and always maintain a sealed fit with the water pipe 24. The interface 210 can be fixedly connected to the housing 21 by fastener connection, and the connector 223 can be positioned and connected with the positioning seat 211 provided on the housing 21, that is, the connector 223 remains relatively stationary in the circumferential direction under the action of the positioning seat 211. There are many specific connection methods between the connector 223 and the positioning seat 211, which can be that the outer wall cross-sectional profile of the connector 223 is non-circular, and the positioning seat 211 is adapted to the outer wall profile of the connector 223; or the outer side of the connector 223 is provided with an inwardly concave positioning groove 2230, and when the connector 223 is sleeved on the positioning seat 211, it can be engaged with the positioning block on the positioning seat 211 through the positioning groove 2230.

[0068] It is understandable that the minimum value of m and n can be selected for the logarithm of the water pipes 24 to reduce the number of water pipes 24 used, thereby reducing costs. Figures 5 to 12 As shown, the value of m is 3, the value of n is 5, and the number of pairs of water pipes 24 is three; accordingly, the number of connection areas corresponding to each water pipe 24 is the value of n being 5. Figures 5 to 12 The combination mode of the cooling assembly 22 shown describes the specific working process of the water pipe 24 in detail.

[0069] It should be noted that the three pairs of water pipes 24 can correspond according to the value of the parameter i corresponding to m, and each connection area in each pair of water pipes 24 can correspond according to the value of the parameter j corresponding to n. The structures of the two water pipes 24 in the same pair are the same or symmetrical, so only one of the water pipes 24 needs to be described. And from the above content, it can be seen that the cut-off cooling components 22 are symmetrically arranged along the middle row and the middle column, so the working process of the water pipes 24 corresponding to i=1 and i=3 is the same, so only one of them needs to be described in the subsequent content.

[0070] It is also important to know that Figures 5 to 12 As shown, there are three working modes of the water pipe 24 corresponding to i=1 and 3, and there are four working modes of the water pipe 24 corresponding to i=2; therefore, there are at least four setting angles for the water pipe 24 to rotate in the circumferential direction; for the convenience of the description of subsequent content, the subsequent content will take the single rotation angle of the water pipe 24 in the circumferential direction as 90° as an example.

[0071] 1. For the water pipe 24 corresponding to i=2, the four working modes generated by the water pipe 24 based on the combination mode of the cooling component 22 are respectively mode 1 to mode 4. In mode 1, if Fig.15 As shown in (1), the five connection areas of the water pipe 24 are all connected to the corresponding cooling components 22. In mode 2, as Fig.15 As shown in (2), the connection area corresponding to position j=3 of the five connection areas of the water pipe 24 is disconnected from the corresponding cooling assembly 22, and the remaining connection areas are connected to the corresponding cooling assembly 22. In mode 3, as Fig.15 As shown in (3), among the five connection areas of the water pipe 24, two connection areas with j=2 and 4 are disconnected from the corresponding cooling components 22, and the remaining connection areas are connected to the corresponding cooling components 22. In mode 4, as Fig.15 As shown in (4), among the five connection areas of the water pipe 24, three connection areas with j=1, 3 and 5 are disconnected from the corresponding cooling components 22, and the remaining connection areas are connected to the corresponding cooling components 22.

[0072] Specifically, Fig.15 As shown, the connection area structures corresponding to positions j=1 and 5 are the same, and three water receiving holes 240 are continuously arranged along the circumferential direction, and the interval angle of adjacent water receiving holes 240 in the circumferential direction is 90°. The connection area structures corresponding to positions j=2 and 4 are the same, and three water receiving holes 240 are continuously arranged along the circumferential direction; and the connection area structures at this position differ from the connection area structures at positions j=1 and 5 by 90° in the counterclockwise direction in the circumferential direction. The connection area corresponding to position j=3 is provided with two water receiving holes 240 at intervals of 180° in the circumferential direction.

[0073] Based on mode 1: Fig.15 As shown in (1), in the connection areas corresponding to j=1 and 5, the water receiving hole 240 at one end is aligned and connected with the through hole 2231 of the corresponding connection head 223, and the remaining water receiving holes 240 are continuous in the counterclockwise direction. In the connection areas corresponding to j=2 and 4, the water receiving hole 240 at the middle position is aligned and connected with the through hole 2231 of the corresponding connection head 223. In the connection area corresponding to j=3, one of the water receiving holes 240 is aligned and connected with the through hole 2231 of the corresponding connection head 223. At this time, all five connection areas are in a conductive state.

[0074] Based on Mode 2: Fig.15 As shown in (2), based on the arrangement of mode 1, the water pipe 24 is rotated 90° in a clockwise direction to obtain the corresponding mode 2.

[0075] Based on model three: Fig.15 As shown in (3), based on the arrangement of mode 1, the water pipe 24 is rotated 180° in a clockwise direction to obtain the corresponding mode 3.

[0076] Based on mode 4: Fig.15 As shown in (4), based on the arrangement of mode 1, the water pipe 24 is rotated 270° clockwise or 90° counterclockwise to obtain the corresponding mode 4.

[0077] It should be known that in Fig.15 In the figure, the direction indicated by the dashed arrow indicates the rotation direction of the water pipe 24, and the view in the dashed line frame is a schematic diagram of the partial cross-sectional structure of each connection area of ​​the water pipe 24 and the corresponding connector 223. The partial cross-sectional view of the connection area and the cooling assembly 22 is indicated by a thick dashed line.

[0078] 2. For the water pipe 24 corresponding to i=1 and 3, the three working modes generated by the water pipe 24 based on the combination mode of the cooling component 22 are mode 1 to mode 3. In mode 1, if Fig.13 and 14 As shown in (1), the five connection areas of the water pipe 24 are all connected to the corresponding cooling components 22.

In mode 3, as Fig.13 and 14 As shown in (3), among the five connection areas of the water pipe 24, three connection areas with j=1, 3 and 5 are disconnected from the corresponding cooling components 22, and the remaining connection areas are connected to the corresponding cooling components 22. Based on the above working mode, there are two specific structures of the water pipe 24 corresponding to i=1 and 3, which will be described in detail below.
