Description

Technical Field

[0001] The present application relates to the technical field of battery pack liquid cooling plate production equipment, and in particular to a liquid cooling plate roll forming mold. Background Art

[0002] Liquid cooling plates are key components in power battery thermal management systems. Liquid cooling systems utilize the high heat transfer coefficient of liquid flow to transfer high amounts of heat. Currently, they are one of the most effective heat dissipation methods, capable of dissipating heat ranging from several hundred watts to several thousand watts. This manufacturer's standard pipe-type liquid cooling plates place coolant pipes directly in contact with the baseplate of the device being cooled. This reduces the number of heat exchange interfaces between the device and the coolant, minimizing thermal resistance and improving performance.

[0003] Generally, liquid cooling plates have to bear weight and dissipate heat. They are generally large in size and often need to be adaptively adjusted as the battery thermal management system is changed. However, due to the large size of liquid cooling plates, the mold opening cost is high and the mold opening cycle is long. At present, the update and iteration of new energy vehicles are accelerating, and the design schemes are often not fully verified due to the cost and cycle. Therefore, it is particularly urgent to find a low-cost liquid cooling plate forming method.

[0004] In related technologies, liquid cooling plates are produced by stamping + cutting + brazing, and the stamping process has the greatest impact on its cost and cycle. Due to the large size of the liquid cooling plate, its molding process requires a large-tonnage press (which requires a large factory area), and the mold structure size is large. Design changes often lead to re-mold opening, which has high costs and long cycles. Summary of the Invention

[0005] An embodiment of the present application provides a liquid cooling plate roller forming mold to solve the problem in the related art that the production and forming process of the liquid cooling plate requires a large-tonnage press, and design changes often lead to secondary mold opening, which has high costs and long cycles.

[0038] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0039] An embodiment of the present application provides a liquid cooling plate roller forming mold, which can solve the problem in the related art that the production and molding process of the liquid cooling plate requires a large-tonnage press, and design changes often lead to secondary mold opening, which has high costs and long cycles.

[0040] See also Figure 1 As shown, the first aspect of the embodiment of the present application provides a liquid cooling plate roll forming mold, comprising:

[0041] The first rolling die set includes a first roller shaft 5 , on the arc surface of which a rolling punch 3 is coaxially and detachably connected. The rolling punch 3 surrounds the outer surface of the first roller shaft 5 and rotates synchronously with the first roller shaft 5 .

[0042] The second roller die set includes a second roller 6, which is spaced apart and parallel to the first roller. A roller die 2, which cooperates with the roller punch 3, is coaxially and detachably connected to the arc surface of the second roller 6. The roller die 2 surrounds the outer surface of the second roller 6 and rotates synchronously with the second roller 6.

[0043] When the first rolling die and the second rolling die move in directions approaching each other and clamp the cut liquid cooling plate blank 4, the first rolling die and the second rolling die rotate synchronously so that the rolling punch 3 and the rolling die 2 cooperate with each other to roll out the set shape of the pattern on the liquid cooling plate blank 4 to form the liquid cooling plate 1.

[0044] The liquid cooling plate roll-forming die of the present embodiment forms the liquid cooling plate product by interlocking the first and second roll-forming dies. By replacing the first roll-forming die 3 and the second roll-forming die 2, products of varying shapes and draw depths can be roll-formed. The specific shapes and draw depths of the roll-forming dies 3 and 2 can be individually designed and molded based on the specific shape of the liquid cooling plate 1; all other components can be shared.

[0045] This forming die leverages the versatility of rollers and their compact footprint, transforming single-direction stamping into continuous, rotary, segmented roll forming. This reduces the forming force and production costs due to the reduced rolling contact area. Furthermore, both the roll punch 3 and roll die 2 can be interchanged to accommodate different liquid cooling plate shapes, reducing the cost of developing new molds.

[0046] In some alternative embodiments: See Figure 2 and Figure 3 As shown, the present embodiment provides a liquid cooling plate roll-forming die. The roll-forming punch 3 of the liquid cooling plate roll-forming die is an arc-shaped sheet structure. The inner arc surface of the roll-forming punch 3 is in contact with the arc surface of the first roller 5, and the outer arc surface of the roll-forming punch 3 is provided with multiple spaced ribs.

[0047] Similarly, the rolling die 2 is an arc-shaped sheet structure, the inner arc surface of the rolling die 2 fits with the arc surface of the second roller shaft 6, and the outer arc surface of the rolling die 2 is provided with a plurality of grooves arranged at intervals, which correspond one to one with the ribs of the rolling punch 3 and are adapted to each other.

[0048] In some alternative embodiments: See Figure 2 and Figure 3As shown, an embodiment of the present application provides a liquid-cooled plate roll-forming mold, wherein the roll-forming punch 3 of the liquid-cooled plate roll-forming mold is provided with multiple pieces, and the multiple roll-forming punches 3 are arranged in sequence along the axial direction and the circumferential direction of the first roller shaft 5, and the roll-forming punch 3 is detachably connected to the first roller shaft 5 through fasteners.

[0049] Similarly, the roller die 2 comprises multiple pieces, which are arranged in sequence along the axis and circumference of the second roller 6. The roller die 2 and the second roller 6 are detachably connected via fasteners. Both the roller die 2 and the roller punch 3 are assembled from multiple pieces, allowing for individual replacement if worn or damaged, reducing processing costs.

[0050] In some alternative embodiments: See Figure 1 and Figure 2 As shown, an embodiment of the present application provides a liquid-cooled plate roll-forming mold, the roll-forming punch 3 of the liquid-cooled plate roll-forming mold is a hollow cylindrical structure, and a plurality of spaced ribs are provided on the outer circular surface of the roll-forming punch 3. The roll-forming punch 3 is sleeved on the first roller shaft 5 and is detachably connected to the first roller shaft 5 by fasteners.

[0051] Similarly, the rolling die 2 is a hollow cylindrical structure with a plurality of spaced grooves on its outer circumference. The rolling die 2 is sleeved on the second roller 6 and is detachably connected to the second roller 6 via fasteners. The rolling die 2 and the rolling punch 3 are both designed as a single piece, ensuring consistent rolling and improving the product quality of the liquid cooling plate 1.

[0052] In some alternative embodiments: See Figure 4 As shown, an embodiment of the present application provides a liquid-cooled plate roll-forming mold, which further includes a frame 8, to which a first roll-forming die set and a second roll-forming die set are both rotatably connected. A drive mechanism (not shown) for driving the first roll-forming die set and the second roll-forming die set to rotate is provided on the frame 8. The drive mechanism can optionally use a servo motor as a power source for the first roll-forming die set.

[0053] The frame 8 is also provided with a longitudinal movement mechanism 9 that drives the first and second rolling dies to move synchronously along the X-axis direction, and a lifting mechanism 10 that drives the first and second rolling dies to move along the Z-axis direction. When the first and second rolling dies are rolling the liquid cooling plate blank 4, the liquid cooling plate blank 4 is in a fixed state to prevent warping and deformation when the liquid cooling plate blank 4 is roll-formed into the liquid cooling plate 1.

[0054] Specifically, the frame 8 includes two parallel and spaced steel side plates, the first rolling die group and the second rolling die group are located between the two steel side plates, and a longitudinal movement mechanism 9 is provided on the side of the two steel side plates that are close to each other to rotate and connect the first rolling die group and the second rolling die group. The longitudinal movement mechanism 9 is used to drive the first rolling die group and the second rolling die group to synchronously reciprocate along the X-axis direction, thereby moving and rolling the fixed liquid-cooled plate blank 4.

[0055] The longitudinal movement mechanism 9 includes two horizontally arranged and parallel transverse slide rails fixed on the steel side plates, and a horizontally arranged transverse slider is slidably connected to each transverse slide rail, and the moving direction of the transverse slider is parallel to the X-axis direction.

[0056] The lifting mechanism 10 includes two longitudinal rails fixedly connected between two horizontally arranged transverse sliders. The longitudinal rails are parallel to each other and spaced apart. Two parallel and spaced lifting sliders are slidably connected to the two longitudinal rails. The lifting sliders move in a direction parallel to the Z-axis.

[0057] A lifting cylinder or hydraulic cylinder is provided between adjacent transverse sliders to drive the lifting sliders to move up and down. The lifting cylinder or hydraulic cylinder drives the lifting sliders to move up and down on the two longitudinal slide rails by extending or shortening the piston rod.

[0058] The first rolling die group and the second rolling die group are respectively installed on two lifting slides that are parallel to each other and spaced apart through bearing seats. When the lifting cylinder or hydraulic cylinder on each lifting slide drives the lifting slide to move up and down on the two longitudinal slide rails, the first rolling die group and the second rolling die group are driven to move in the direction of approaching or moving away from each other.

[0059] The longitudinal movement mechanism 9 also includes a linear module fixed on the steel side plate. The driving slider of the linear module is rotatably connected to the lifting slider through a rocker rod. The connecting rod is rotated to enable the lifting slider to move up and down, and after the lifting slider reaches the set height, the linear module drives the lifting slider, the longitudinal slide rail and the transverse slide rail to move linearly along the X-axis direction relative to the transverse slide rail.

[0060] See also Figure 1 and Figure 5 As shown, the second aspect of the embodiment of the present application provides a liquid cooling plate roll forming mold, comprising:

[0061] The first rolling die set includes a first roller shaft 5 , on the arc surface of which a rolling punch 3 is coaxially and detachably connected. The rolling punch 3 surrounds the outer surface of the first roller shaft 5 and rotates synchronously with the first roller shaft 5 .

[0062] The second rolling die set includes a flat die 7 separated from the outer circumference of the first roller shaft 5 ; a stamping groove adapted to the rolling punch 3 is provided on a side of the flat die 7 facing the rolling punch 3 .

[0063] The first and second rolling dies mesh similarly to a gear and rack structure, rolling to form the cooling plate 1 with a large draw depth. The specific shapes and draw depths of the rolling punch 3 and flat die 7 can be designed and molded separately based on the specific shape of the cooling plate 1, while all other components can be shared.

[0064] When the first rolling die set and the second rolling die set move in directions approaching each other and clamp the liquid cooling plate blank 4, the first rolling die set and the second rolling die set rotate synchronously so that the rolling punch 3 and the rolling die 2 cooperate with each other to roll out a set shape of texture on the liquid cooling plate blank 4 to form the liquid cooling plate 1.

[0065] The liquid cooling plate roll forming mold of the embodiment of the present application realizes the liquid cooling plate product forming by the mutual roll-pressing engagement of the first rolling module group and the second rolling module group. By replacing the rolling punch 3 of the first rolling module group and the flat-plate die 7 of the second rolling module group, the roll forming of different products can be realized.

[0066] This forming die leverages the versatility of rollers and their compact footprint, transforming single-direction stamping into continuous, rotary, segmented roll forming. This reduces the forming force due to the reduced rolling contact area, lowering production costs. Furthermore, both the roll punch 3 and the flat die 7 can be interchanged to accommodate different liquid cooling plate 1 shapes, reducing the cost of redeveloping the mold.

[0067] In some alternative embodiments: See Figure 5 As shown, an embodiment of the present application provides a liquid-cooled plate roller-forming mold, which also includes a frame 8, a first roller-forming module group is rotatably connected to the frame 8, and a second roller-forming module group is fixed on the frame 8. A driving mechanism (not shown in the figure) for driving the first roller-forming module group to rotate is provided on the frame 8, and the driving mechanism can select a servo motor as the power source of the first roller-forming module group.

[0068] Frame 8 is also equipped with a longitudinal movement mechanism 9 that drives the first rolling die set to move synchronously along the X-axis, and a lifting mechanism 10 that drives the first rolling die set to move along the Z-axis. The longitudinal movement mechanism 9 is used to drive the first rolling die set to move linearly relative to the second rolling die set along the X-axis after the first and second rolling dies engage with each other. When the first and second rolling dies are rolling against the liquid-cooling plate blank 4, the liquid-cooling plate blank 4 is fixed, preventing warping and deformation during roll-forming of the liquid-cooling plate blank 4 into the liquid-cooling plate 1.

[0069] The lifting mechanism 10 is used to drive the first and second roller pressing dies to move up and down in a direction toward or away from each other. When the first and second roller pressing dies are driven toward each other, they clamp the liquid cooling plate blank 4. When the first and second roller pressing dies are driven away from each other, they release the liquid cooling plate 1 after roll forming.

[0070] Specifically, the frame 8 includes two steel side plates that are parallel to each other and spaced apart. The first rolling die group and the second rolling die group are located between the two steel side plates. A longitudinal movement mechanism 9 that is rotatably connected to the first rolling die group is provided on the side of the two steel side plates that are close to each other. The longitudinal movement mechanism 9 is used to drive the first rolling die group to synchronously reciprocate along the X-axis direction, thereby moving and rolling the liquid-cooled plate blank 4 fixedly set on the flat-plate die 7.

[0071] The longitudinal movement mechanism 9 includes two horizontally arranged and parallel transverse slide rails fixed on the steel side plates, and a horizontally arranged transverse slider is slidably connected to each transverse slide rail, and the moving direction of the transverse slider is parallel to the X-axis direction.

[0072] The lifting mechanism 10 includes two longitudinal rails fixedly connected between two horizontally arranged transverse sliders. The two longitudinal rails are parallel to each other and spaced apart. A lifting slider is slidably connected to the two longitudinal rails, and the movement direction of the lifting slider is parallel to the Z-axis direction.

[0073] A lifting cylinder or hydraulic cylinder is provided between the transverse slider and the lifting slider to drive the lifting slider to move up and down. The lifting cylinder or hydraulic cylinder drives the lifting slider to move up and down on the longitudinal slide rail by extending or shortening the piston rod.

[0074] The first rolling die set is installed on the lifting slider through the bearing seat. When the lifting cylinder or hydraulic cylinder on the lifting slider drives the lifting slider to move up and down on the two longitudinal slide rails, the first rolling die set and the second rolling die set are driven to move in the direction of approaching or moving away from each other.

[0075] The longitudinal movement mechanism 9 also includes a linear module fixed on the steel side plate. The driving slider of the linear module is rotatably connected to the lifting slider through a rocker rod. The connecting rod is rotated to enable the lifting slider to move up and down, and after the lifting slider reaches the set height, the linear module drives the lifting slider, the longitudinal slide rail and the transverse slide rail to move linearly along the X-axis direction relative to the transverse slide rail.

[0076] How it works

[0077] An embodiment of the present application provides a liquid-cooled plate roller-forming mold. Since the liquid-cooled plate roller-forming mold of the present application is provided with a first roller-forming mold group, the first roller-forming mold group includes a first roller shaft 5, and a roller-forming punch 3 is coaxially and detachably connected to the circular arc surface of the first roller shaft 5; a second roller-forming mold group includes a second roller shaft 6 that is parallel to and spaced apart from the first roller shaft 5; a roller-forming die 2 that cooperates with the roller-forming punch 3 is coaxially and detachably connected to the circular arc surface of the second roller shaft 6.

[0078] Therefore, the liquid cooling plate roll forming mold of the present application realizes the liquid cooling plate 1 product forming by the mutual roll-pressing engagement of the first rolling mold group and the second rolling mold group. By replacing the rolling punch 3 of the first rolling mold group and the rolling die 2 of the second rolling mold group, the roll forming of different products can be realized. The forming mold makes full use of the versatility of the roller and occupies a small space, and converts the single stamping forming in a single direction into continuous rotary segmented forming. Since the rolling contact area is small, the forming force is reduced and the production cost is reduced.
