Description

Technical Field

[0001] The present application relates to the technical field of metal parts processing, and in particular to an expansion tube assembly processing device and a monitoring method and system thereof. Background Art

[0002] The heat exchanger, as a heat exchange device, has multiple heat exchange tubes inside the device. The working fluid in the heat exchange tubes transfers heat to the medium outside the heat exchange tubes through the heat exchange tubes to achieve heat exchange.

[0003] There is a step in the processing technology of heat exchange tubes: tube expansion; currently, tube expansion is often carried out in groups. The process is briefly described as follows: multiple horizontal solid rods are fixed on a vertical plate surface as a tube expansion structure, the tube sheet with the heat exchange tubes inserted is placed in front and the heat exchange tubes are positioned, and then the vertical plate surface is moved toward the tube sheet. During the process, the solid rods are gradually inserted into the ends of the heat exchange tubes to complete the tube expansion.

DETAILED DESCRIPTION

[0054] The following is combined with Figure 1-5 This application is described in further detail.

[0055] An embodiment of the present application discloses a heat exchanger structure.

[0056] Reference Figure 1The heat exchanger structure includes a tube sheet 4 and a heat exchange tube 5. There are multiple heat exchange tubes 5. The heat exchange tubes 5 are inserted into the pre-opened through holes in the tube sheet 4 and arranged along the length direction of the tube sheet 4. They are then sent to the expansion tube assembly processing device of the present application to expand the ends of the heat exchange tubes to complete the assembly and fixation of the heat exchange tubes.

[0057] It should be noted that compared with the traditional group of single pipe diameter, during use, the group of heat exchange tubes are processed with different pipe diameters. After using them to form a heat exchanger, the staff can adjust the heat exchange efficiency of the heat exchanger in a small range by only changing the flow rate of the pipe with a smaller diameter. At this time, the accuracy is higher and the energy consumption is lower.

[0058] The embodiment of the present application discloses a tube expansion assembly processing device.

[0059] Reference Figure 2-Figure 5 The tube expansion assembly processing device includes a tube expansion mechanism 1, a push block mechanism 2 and a controller 3, wherein the tube expansion mechanism 1 includes a flat push plate 11, a movable block 13 movably mounted on the flat push plate 11 and an expansion rod 15 mounted on the movable block 13, there are multiple movable blocks 13, the number of expansion rods 15 corresponds to the number of the movable blocks 13, the diameters of the multiple expansion rods 15 are divided into multiple groups, and the diameters of the expansion rods 15 in the same group are the same. It can be understood that the outer end of the expansion rod 15 should be fixed with an expansion head (elliptical head, round head) during the use stage to guide the insertion of the heat exchange tube to be expanded.

[0060] When in use, the controller 3 controls the block pushing mechanism 2 to move the movable block 13, thereby changing the expansion rod 15 that has been in effect in previous processing, so as to flexibly match the diverse processing requirements of the heat exchange tube.

[0061] The following is a detailed explanation:

[0062] It can be understood that the present application is part of the production line, so the push plate 11 can be installed on the production line machine base and is horizontally slidably connected; example: a slide groove is formed on the production line machine base, the end of the slide groove is open, and the push plate 11 is slidably connected in the slide groove; the push plate 11 extends vertically.

[0063] The tube expansion mechanism 1 also includes an electric cylinder 12, the cylinder body of which is fixed on the above-mentioned production line machine base with a corresponding seat structure and placed horizontally, and the telescopic end of the electric cylinder 12 is fixed to the flat push plate 11, and is used to push and pull the flat push plate 11 to slide along the above-mentioned slide groove. The interior of the flat push plate 11 is a hollow structure with both ends of the inner cavity open, and the movable block 13 is located in the inner cavity of the flat push plate 11 and is connected in a sliding manner. There are multiple movable blocks 13 and they are arranged in an array. The inner cavity of the flat push plate 11 has at least one position for the movable block 13 vacant, and in this embodiment, one row is preferably vacant.

[0064] The tube expansion mechanism 1 further includes a limit assembly 14, which is used to clamp the movable block 13 and is located between the push plate 11 and the movable block 13, so that the movable block 13 can be located inside the push plate 11 and will not separate from the push plate 11 during operation. An expansion rod 15 is fixed to the movable block 13, and there are multiple expansion rods 15, each expansion rod 15 corresponds to a movable block 13, and the expansion rods 15 have multiple diameters.

[0065] In this embodiment, the expansion rods 15 located at the bottom row are defined as expansion rods 15 used for tube expansion. The multiple movable blocks 13 change positions to combine expansion rods 15 of different diameters to process heat exchange tubes 5 of different diameters (or tube expansion sizes).

[0066] Reference Figure 2 and Figure 3 The push block mechanism 2 includes a cross slide 21, an adsorption component, a push rod 22 and a camera 23.

[0067] Among them, the cross slide 21 is fixed to the above-mentioned production line machine base with a gantry structure. The cross slide 21 has two driving directions, vertical and horizontal, in the embodiment of the present application. The push rod 22 is fixed to the slider of the cross slide 21, and the adsorption component is fixed to the end of the push rod 22 away from the cross slide 21 and is used to adsorb the movable block 13. The camera 23 is installed at any position in the workshop, and its camera end is required to face the flat push plate 11 and can collect the image of the expansion rod 15. The cross slide 21 and the camera 23 are electrically connected to the controller 3.

[0068] In this embodiment, the controller 3 includes a PLC control cabinet and a computer. The PLC control cabinet is electrically connected to the cross slide 21 , and the camera 23 and the PLC control cabinet are electrically connected to the computer to meet the requirements of human-computer interaction and numerical control.

[0069] In this embodiment, an adsorption component is fixed at the end of the push rod 22, so that the present application can move the movable block 13 by adsorbing the movable block 13 to meet the demand of changing the position of the movable block 13; the camera 23 is installed, so that the controller 31 can identify the image transmitted back by the camera 23, analyze and determine which movable block 13 needs to be changed, making the adjustment of the movable block 13 more convenient.

[0070] In one embodiment of the present application, the adsorption assembly includes an electromagnet 24 and an iron sheet, the electromagnet 24 is fixed to the end of the push rod 22, the iron sheet is embedded or buried and fixed to the side of the movable block 13 facing the push rod 22, and the electromagnet 24 is electrically connected to the controller 3 (such as: the above-mentioned PLC control cabinet). During use, the controller 3 controls the electromagnet 24 to be powered on and off to achieve adsorption or non-adsorption of the movable block 13.

[0071] It is understandable that, in addition to adding an iron sheet to the movable block 13, the movable block 13 as a whole can also be designed as a ferromagnetic structure, but considering the weight, a hollow setting is preferably made.

[0072] The movable block 13 slides on the push plate 11, and the expansion rod 15 is fixed on the movable block 13. In conjunction with the adsorption component and the camera 23, the position of the expansion rod 15 can be automatically adjusted by setting the controller 3. Therefore, the present application can relatively conveniently and efficiently arbitrarily combine the expansion rods 15 according to processing requirements to meet diverse processing requirements.

[0073] In another embodiment of the present application:

[0074] The adsorption component includes a suction cup, the adsorption surface of the suction cup faces the movable block 13, the push rod 22 is hollow inside and has an open end, the open end of the push rod 22 is connected to the suction cup, and the other end is fixed to the slider of the cross slide 21, the side wall of the push rod 22 has a hole and is connected to the internal cavity, the push rod 22 is externally connected to an air pump, the air pipe of the air pump is connected to the opening on the side wall of the push rod 22, the air pump is electrically connected to the controller 3, and can cooperate with the information feedback from the camera 23 to control whether the air pump draws air.

[0075] By using the air pump to suck gas, the suction cup can be controlled to adsorb the movable block 13. When the movable block 13 is moved to the specified position, the air pump is controlled to deflate, thereby stopping the adsorption of the movable block 13, so that the movable block 13 and the expansion rod 15 can be more conveniently replaced and combined.

[0076] In another embodiment of the present application, the side wall of the movable block 13 facing the camera 23 is marked with a code, and the code examples are: 1, 2, 3... The code is provided so that the controller 3 can more efficiently identify each movable block 13 to facilitate position adjustment. Because if there is no code, the controller 3 needs to track and record all the trajectories of each movable block 13 to determine which one needs to be moved, or calculate the diameter of the expansion rod 15 through image measurement and then use it to identify the corresponding movable block 13.

[0077] In another embodiment of the present application, because when adjusting the movable block 13 used for expanding the tube, it may be necessary to adjust more than one movable block 13, so it is relatively time-consuming to move them one by one, so the following settings are made:

[0078] A push plate 25 is fixed at the end of the push rod 22 , and multiple electromagnets 24 are evenly fixed on the side of the push plate 25 facing the flat push plate 11 . The multiple electromagnets 24 should be distributed in an array, and the size of the push plate 25 is at least larger than any one of the movable blocks 13 .

[0079] When the camera 23 captures the coded information, the controller 3 determines which movable blocks 13 need to be controlled to move and which ones can move together, and then energizes multiple electromagnets 24 to simultaneously push multiple movable blocks 13, making the expansion tube structure adjust faster and more efficient.

[0080] Reference Figure 5 The limiting assembly 14 includes a clamping block 141 and a clamping block 142. The clamping block 141 is two and is respectively fixed to the inner side wall and the inner top surface of the push plate 11. The clamping block 141 extends toward the movable block 13. A groove 1 corresponding to the clamping block 141 is dug on the movable block 13.

[0081] The second clamping block 142 is fixed to a side wall of the clamping block 141 of the movable block 13 away from the side, and two adjacent movable blocks 13 are clamped through the groove 1 and the clamping block 142. The inner wall of the push plate 11 away from the clamping block 141 is provided with a groove 2, which is clamped with the clamping block 142 of the movable block 13 in conflict. By providing the clamping block 141 and the clamping block 142, the movable block 13 can be clamped in the push plate 11, and the movable block 13 can not fall off the push plate 11.

[0082] According to the above arrangement, the movable block 13 will not fall out unless a complete column and a complete row are vacated.

[0083] The embodiment of the present application also discloses a monitoring method for an expansion tube assembly processing device.

[0084] The monitoring method of the expansion tube assembly processing device includes:

[0085] 1) If the current equipment state meets the preset tube expansion condition, a real-time image of the movable block 13 on the push plate 11 is obtained.

[0086] The device status may be determined by the controller 3, such as: power-on status, power-off status, self-test completion; meeting preset expansion conditions, for example: self-test completion and no faults.

[0087] 2) Perform coding recognition on the real-time image to obtain coding distribution information, and search the preset database to determine the current expansion tube specification distribution information.

[0088] The above database stores the expansion rod 15 and its diameter and applicable processing range corresponding to any code. Identifying codes in images is a prior art, so it will not be described in detail.

[0089] 3) Obtain production demand data and analyze it to obtain target expansion tube specification distribution information.

[0090] Production demand data, example: a group of heat exchange tubes are numbered J1-J3, J1 and J3 are expanded to d1, and J2 is expanded to d2, then the distribution information is d1, d2, d1.

[0091] 4) Based on the preset movement logic, the current expansion tube specification distribution information and the target expansion tube specification distribution information are processed, and the cross slide 21 and the electromagnet 24 are controlled to work.

[0092] According to the above configuration, the device can recognize the expansion tube specification distribution information through images, and automatically control the cross slide 21 and the electromagnet 24 to complete the position adjustment of the expansion rod 15 in effect according to the target expansion tube specification distribution information corresponding to the production demand.

[0093] In another embodiment of the method, the method further comprises:

[0094] 1) Define the current scene as a one-by-one electromagnetic shift scene (i.e., move the active blocks 13 one by one), and generate a shift track 1 based on the movement logic; Example:

[0095] Example: The requirements are 1, 3, 5; currently at the bottom are 1, 3, 6, 5 is above 6, and there is an empty column on the side, then it is determined that 6 needs to be adjusted to 5, and the movement trajectory is: move 6 one step to the empty position, 5 is on 6, and the displacement occurs synchronously; then move 5 one step to the original position, and end; at the end, 5 is suspended in the air without external force, and falls to the original position of 6, completing the displacement.

[0096] According to the above, the movement logic is to absorb one movable block 13 at a time and drive it to move; the generation of previous trajectories refers to the shifting rules of the game "Huarong Road". When manpower is not considered, the staff will exhaustively verify and record the generation history records, and search and compare the history records.

[0097] 2) Calculate the shift time parameter 1 based on the shift trajectory 1 and the preset cross slide working parameters.

[0098] Example: Get the number of moving steps from moving trajectory one, and determine how much time is required for each moving step from the working parameters (design parameters) of the cross slide, thereby calculating the time required to complete moving trajectory one, that is, the above-mentioned shift time parameter one.

[0099] 3) If the displacement time parameter exceeds the preset expansion interval, execute the next step.

[0100] It is understandable that, as an automated equipment of the production line, it needs the cooperation of other equipment during the production process. In order to ensure the continuity of the front and back processing, each device has its own frequency. Therefore, the device of the present application has its own fixed expansion interval. If the shift time parameter is exceeded and other equipment does not have the ability to follow and adaptively adjust, it will cause production errors. Therefore, this method executes the next step.

[0101] 4) Define the current scene as a multi-point synchronous shift scene, and generate a shift trajectory 2 based on the movement logic.

[0102] Example: The requirements are 1, 3, and 5. Currently, the bottom layer is 1, 3, and 6. 5 is one row above 6 and to the side. There is an empty row to the side of 5. At this time, the second moving track is:

[0103] 6 and 5 are selected at the same time (the corresponding ones are attracted by the electromagnet 24), and then moved sideways together by one step, and the end is completed; at the end, 5 is suspended in the air and falls to the original position of 6, and the position is completed.

[0104] According to the above, at this time, the movement logic is to absorb multiple movable blocks 13 at a time and drive them to move; the previous trajectories and the movement trajectory are the same.

[0105] 5) According to the second displacement track, the cross slide 21 and the electromagnet 24 are controlled to work (ie, power on and off, magnetism on and off).

[0106] According to the above configuration, the requirements for other equipment in the production line can be reduced, thereby improving the use effect of the device of the present application.

[0107] In another embodiment of the method, the method further comprises:

[0108] The second shifting time parameter is calculated based on the second shifting trajectory and the preset working parameters of the cross slide; similarly, the calculation is performed based on the number of steps and the time consumption of each step;

[0109] If the second displacement time parameter exceeds the preset expansion interval, the time difference is calculated, and the moving speed of the slider of the cross slide 21 is adjusted according to the time difference; for example: if it exceeds 3s, moves 3 steps, and one step differs by 1s, then the time required for the original slider to move one step is subtracted by 1s to obtain the new time for each step, and then the recorded distance of each step is called to calculate the new speed. The speed adjustment of the slider is the speed adjustment of the motor corresponding to the slider, so it will not be repeated.

[0110] In another embodiment of the present application, the push rod 22 is an electrically controlled telescopic structure, such as an electric cylinder; correspondingly, the method further includes:

[0111] The currently required thrust value is calculated according to the production demand data and the preset expansion thrust calculation rules; for example: the production demand data indicates that three heat exchange tubes need to be expanded, each with a thrust of n, and the currently required thrust value is 3n.

[0112] If the currently required thrust value exceeds the preset deformation risk threshold (thrust that may cause the clamping block 141 and the second clamping block 142 to have an irreversible deformation risk), the push rod 22 and the electric cylinder 12 are controlled to extend and retract synchronously.

[0113] This arrangement allows the aforementioned push plate 25 to be reused, and cooperates with the connection structure of the movable block 13 to reduce the probability of deformation; at the same time, it ensures that the entire push plate 11 is not subjected to a single point of force when moving, thereby reducing the probability of damage.

[0114] It should be noted that in the present application, if the movement logic of the moving activity in the push plate 11 includes moving a certain movable block 13 upward to leave it temporarily vacant underneath, it is either necessary to intervene manually or with a robotic arm to temporarily fix the suspended movable block 13, or to build electromagnetic cores into all the movable blocks 13 to determine whether the movable blocks 13 can be separated from each other by controlling each electromagnetic core.

[0115] The embodiment of the present application also discloses a tube expansion assembly processing system.

[0116] The tube expansion assembly processing system includes the tube expansion assembly processing device described above, and the controller 3 is configured to execute the contents described in the above method.

[0117] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
