[0037] The utility model provides a flattening tool, which can be used to flatten bulging, warping, etc. of the coating layer of metal parts such as aluminum copper bars, but is not limited here.

[0038] Reference Figures 1 to 3In one embodiment of the utility model, the flattening tool 100 includes a supporting component 10 and a flattening component 20. The flattening component 20 and the supporting component 10 can be relatively far away from or close to each other. The flattening component 20 and the supporting component 10 have opposing surfaces formed with a mimetic receiving portion 11 suitable for at least matching the shape of the bulge section of the workpiece to be flattened. A flow channel is provided in the flattening component 20 and / or the supporting component 10, and the flow channel is suitable for passing a heat exchange medium for heating and / or cooling the workpiece to be flattened.

[0039] In this embodiment, the support component 10 may be a block or plate-shaped structure, etc., and the flattening component 20 may be roughly the same shape as the support component 10, and the opposing surfaces of the two are recessed to form a contoured cavity for accommodating the bulging section of the piece to be flattened or the entire piece to be flattened.

[0040] It should be noted that the heat exchange medium can be a liquid heat exchange medium such as water or oil, or a gas heat exchange medium, which is not limited here. The heat exchange medium plays different roles at different temperatures. The heat exchange medium introduced by the flattening tool 100 of the utility model can have only a cooling effect, or only a heating effect, or both cooling and heating effects, which is not limited here.

[0041] When making the flattening tool 100, the 3D printing technology can be used to make a conformable water channel mold, and the upper mold and the lower mold, that is, the flattening component 20 and the supporting component 10, can be made separately. The utility model can realize rapid heat transfer between the plastic surface and the heating mold, improve production efficiency, and reduce heat damage.

[0042] In this embodiment, water is preferably used as the heat exchange medium. Water is easily available and inexpensive. The large specific heat capacity of water can be used to achieve rapid heating and cooling of the plastic surface through alternating circulation of hot and cold water. The temperature can be kept within a smaller range so that the plastic properties will not change and the performance of the copper and aluminum busbars will not be affected.

[0043] It can be understood that the utility model provides a flattening tool 100, which can realize semi-automation or full automation of flattening operations, can reduce the intensity of manual work, and even eliminate the need for manual operation, which helps to save labor costs; and, mechanized flattening operations can effectively ensure the stability of the pressing force, which is beneficial to improving the flattening effect, and production efficiency can also be greatly improved, and product quality is better.

[0044] In order to further improve production efficiency and ensure the stability of pressing force, so as to further improve product quality, refer to Figures 1 to 3 In one embodiment, the flattening tool 100 may further include a driving member, which is drivingly connected to the flattening component 20 to drive the flattening component 20 away from or close to the supporting component 10.

[0045] In this embodiment, the driving member may be a motor, a cylinder, or an oil cylinder, etc., which is not limited here.

[0046] In one embodiment, if Figure 1 and Figure 2 As shown, the flattening tool 100 may also include a plurality of temperature sensors 30, which are arranged on the flattening component 20 and / or the supporting component 10 and are used to detect the temperature of the flattening component 20 and / or the supporting component 10, so as to adjust the real-time temperature of the medium introduced, thereby ensuring the heating and cooling effect, so that the outer bulge of the aluminum copper bar can be better flattened. In addition, the automatic opening and closing of the mold can be realized by detecting the mold temperature, which is conducive to improving production efficiency.

[0047] In one embodiment, if Figure 1 and Figure 2 As shown, the flattening tool 100 may also include a fixed base plate 40, a support column 50 disposed on the fixed base plate 40, and a fixed seat 60 disposed on the support column 50. The flattening component 20 may be slidably disposed on the fixed seat 60 via a heat insulating block 70, and the support component 10 may be fixed on the fixed seat 60 via the heat insulating block 70. In this way, the flattening component 20 may slide open and close more stably, and more than two sets of molds (support component 10 and flattening component 20) may be disposed in the height direction of the support column 50 to simultaneously process more than two workpiece flattening operations, which may greatly improve production efficiency.

[0048] In this embodiment, in order to make it easier for manual or mechanical hands to pick up and place workpieces, the fixing seat 60 can be adjusted in height and position on the support column 50. Specifically, a strip groove extending along the length direction of the support column 50 can be provided, and the fixing seat 60 can be clamped on the support column 50 through a clamp block and locked by a locking member such as a bolt or a screw. A slider is protruded at a position corresponding to the strip groove on one side of the clamp block connected to the fixing seat 60. When the height of the fixing seat 60 needs to be adjusted, it is only necessary to loosen the locking member, slide the clamp block to the target position, and then lock the locking member.

[0049] In some application scenarios, when the heat exchange medium is only used as a cooling medium or the heating effect is relatively limited, an electric heating element such as a heating rod or sheet can be set in the flattening tooling 100. The electric heating element can be set on the flattening component 20 and / or the supporting component 10 and used to heat the workpiece to be flattened. This can meet the heating requirements of the bulge on the workpiece to be flattened, and can further improve the product performance, size and appearance requirements of the workpiece to be flattened.

[0050] The present invention further proposes an automatic flattening device, which includes a flattening tool 100. The specific structure of the flattening tool 100 refers to the above-mentioned embodiment. Since the automatic flattening device proposed by the present invention includes all schemes of all embodiments of the above-mentioned flattening tool 100, it has at least the same technical effects as the above-mentioned flattening tool 100, which will not be elaborated here one by one.

[0051] Reference Figures 1 to 3 In one embodiment of the utility model, the automatic flattening device includes a flattening tool 100, a frame 200 and a medium supply device (not shown); wherein, the number of the flattening tool 100 is at least one, and the flattening tool 100 is arranged on the frame 200; the flow channel of the medium supply device and the flattening tool 100 can be connected through a pipeline, and a manual valve, an electric valve, a sensor, a flow meter, etc. can be arranged on the pipeline, and the medium supply device can be arranged on the frame 200, and can also be arranged next to the frame 200, which is not limited here.

[0052] In order to make the heat exchange medium have both heating and cooling functions, and make the tooling temperature of the heat exchange medium more accurate, so as to improve the bulge flattening effect, such as Figure 1 As shown, in one embodiment, the automatic flattening device may further include a temperature controller, which is disposed between the medium supply device and the flattening tool 100 and is used to control the temperature of the heat exchange medium. In this embodiment, the temperature controller is preferably a cold-hot conversion water temperature controller, which is not limited here.

[0053] In this embodiment, the automatic flattening device may further include a control device 400 with a touch screen or a non-touch screen, and the control device 400 is electrically connected to the flattening tool 100 and the medium supply device, respectively, to control the flattening tool 100 and the medium supply device to work. It can be understood that such a setting can further improve the flattening efficiency and help to achieve a fully automated flattening operation.

[0054] In order to meet the requirements of flattening the bulge of the aluminum copper busbar, the volume of the flattening tool 100 is reduced, such as Figure 1 and Figure 3 As shown, in one embodiment, the automatic flattening equipment may further include a product positioning seat 300, which is disposed on the frame 200 and located on one side of the flattening tooling 100. A limiting groove 301 may be recessed on the product positioning seat 300 to support and position the non-bulging processing section of the piece to be flattened.

[0055] In addition, the main reference Figure 1 In some embodiments, the automatic flattening equipment can also be provided with a plurality of flattening tools 500 to flatten the warped and other deformed parts on the workpiece to be flattened. The flattening tools 500 can also include an upper and lower mold part. The opposing surfaces of the upper mold and the lower mold can be set as a plane to flatten the warped and other deformed parts.

[0056] In the utility model, the product is positioned by the product positioning seat 300, and the corresponding contoured flattening tooling 100 is placed according to the bulging conditions of each bending point of the product. The product positioning seat 300 and the flattening tooling 100 are a multi-layer stacking structure to improve the product flattening rhythm. The flattening tooling 100 has multiple sets of temperature sensors 30 built in to trigger and control the clamping and releasing actions of the flattening process. The flattening tooling 100 is designed with a 3D flow channel conformal design based on the shape of the product, which ensures strength while increasing the flow channel surface area to meet the realization of extremely cold and extremely hot functions. The flattening tooling 100 can quickly replace and fix the corresponding tooling according to the flattening requirements of products of different specifications, which can reduce debugging time and cost.

[0057] When the automatic flattening equipment of the present invention is used for flattening operation, the specific process is as follows: first, a person or a robot puts the product into the product holder 60, and starts the switch button with both hands; then, the system is triggered according to the selected or default program, and the temperature controller adjusts the temperature of the heat exchange medium to the corresponding set target temperature, and then controls each flattening tool 100 to perform the corresponding flattening action according to the corresponding setting; after the product bulge is softened and flattened by heat, the hot and cold conversion water temperature control machine quickly outputs heat exchange media such as low-temperature and high-pressure water or oil to the flattening tool 100, and performs extremely cold solidification on the product; when the cooling temperature reaches the corresponding set value, the system controls each flattening tool 100 to perform the corresponding loosening action according to the corresponding setting, and then a person or a robot takes out the product and puts it into the corresponding collection place. At the same time, the hot and cold conversion water temperature control machine can quickly output high-temperature and high-pressure water or oil to the flattening tool 100, and extremely heat the tool in preparation for the next round of flattening operation.

[0058] It can be understood that the automatic flattening equipment of the utility model can accurately control the temperature of the heat exchange medium delivered to the flattening tooling 100, so that the plastic surface of the metal part can be quickly heated and softened without destroying the plastic molecular structure due to too high a temperature. After the plastic surface is quickly hardened, the surface is smooth and the thickness dimension data meets the requirements.

[0059] The results of the aluminum copper busbar cladding bulge flattening test performed by the utility model automatic flattening equipment are shown in Table 1 below:

[0060] Table 1 Aluminum copper busbar coating bulge flattening test table

[0061]

[0062] It can be found from the above table that the utility model adopts extremely cold and extremely hot processes to flatten the bulges of the aluminum-copper busbar coating. When the target heating temperature is 115-165°C, the bulge flattening effect of the automatic flattening equipment is better, and the flattening effect and method are better.

[0063] In addition, by adopting the automatic flattening equipment and process of the utility model, production efficiency is significantly improved and costs are greatly reduced:

[0064] The manual tightening tooling process of 111.2s (5 people) and the disassembly tooling process of 35.26s (1 person) are cancelled, and replaced with the automatic pressing process of the utility model, with a production cycle of 120s; the tunnel furnace operation mode is cancelled, energy consumption is reduced, and the operation site is saved.

[0065] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
