Wherein like elements in different embodiments are numbered with like associated elements. In the following description, numerous details are set forth in order to provide a better understanding of the present application. However, those skilled in the art will readily recognize that some of the features may be omitted or replaced with other elements, materials, methods in different instances. In some instances, certain operations related to the present application have not been shown or described in detail in order to avoid obscuring the core of the present application from excessive description, and it is not necessary for those skilled in the art to describe these operations in detail, so that they may be fully understood from the description in the specification and the general knowledge in the art.
Furthermore, the features, operations, or characteristics described in the specification may be combined in any suitable manner to form various embodiments. Also, the various steps or actions in the method descriptions may be transposed or transposed in order, as will be apparent to one of ordinary skill in the art. Thus, the various sequences in the specification and drawings are for the purpose of describing certain embodiments only and are not intended to imply a required sequence unless otherwise indicated where such sequence must be followed.
The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning. The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).
At present, two modes of normal-temperature cold die stamping and heating hot die stamping are mainly adopted in the industry, and plate blanks with high heat conductivity coefficient and poor ductility, such as aluminum alloy, are manufactured into an upper-layer liquid-cooled plate; the normal-temperature cold die stamping has the problems of difficulty in controlling flatness, easiness in cracking of plates, poor size precision and the like, while the heating hot die stamping can solve the problems of difficulty in controlling flatness, easiness in cracking of plates and the like to a certain extent, but has the problems of high energy consumption, low operation efficiency and the like; meanwhile, no matter the normal-temperature cold die stamping or the heating hot die stamping is adopted, when the upper-layer liquid-cooled plate is stamped, a plate blank is required to be placed between a male die head and a female die head of a stamping machine, and a runner structure is stamped on the plate blank by utilizing opposite stamping movement between the male die head and the female die head, so that the forming processing of the upper-layer liquid-cooled plate is completed; however, when the structure or layout of the flow channel designed on the upper liquid cooling plate changes, the male die head and the female die head matched with the structural layout of the preset flow channel need to be replaced or configured, so that the manufacturing cost of the liquid cooling plate can be greatly increased.
According to the forming method of the liquid cooling plate of the battery, the electromagnetic pulse technology is adopted, and the runner structure can be punched on the plate blank only by utilizing the pressure-bearing template with the runner model, so that the upper layer liquid cooling plate is manufactured; when the structural layout of the runner changes, only the pressure-bearing template needs to be selected or replaced, compared with a driving die stamping method, the manufacturing cost of the upper-layer liquid cooling plate can be effectively reduced, the forming speed is high, the production efficiency is high, and the method is suitable for a clean production process.
Referring to fig. 1 to 6, an embodiment of a method for forming a liquid cooling plate of a battery mainly uses an electromagnetic pulse technology, and a pressure-bearing template 10 having a flow channel model a is used to stamp a flow channel cavity structure adapted to the flow channel model a on a metal plate blank 20, so as to complete the forming operation of the upper layer liquid cooling plate of the battery; referring to fig. 1, the molding method includes steps 101 to 103, which are described below.
Referring to fig. 2, 3 and 4, in one embodiment, the pressure-bearing die plate 20 is mainly a die head structure similar to the conventional stamping device, that is: the pressure-bearing template 10 has two parts, namely a plane part b and a runner model a, wherein the runner model a adopts a concave structure distributed in the plane part b, and the specific size, shape, trend and the like of the runner model a can be selectively arranged according to a pre-designed runner, for example, a raised strip structure form with the shape of snake shape, spiral shape, F shape, W shape and the like is adopted. When the pressure-bearing die plate 10 is placed in parallel with the metal slab 20 at an interval, the plane portion b is used to contact the metal slab 20 so that the metal slab 20 can entirely cover the runner model a, and an interval of a certain distance is formed between the metal slab 20 and the runner model a to create a condition for deformation of a region portion of the metal slab 20 opposite to the runner model a.
Referring to fig. 5, in another embodiment, the pressure-bearing die plate 20 is mainly a punch head structure similar to the conventional punching device, that is: the pressure-bearing template 10 has two parts, namely a plane part b and a flow channel model a, wherein the flow channel model a adopts a convex structure distributed in the plane part b, and the specific size, shape, trend and the like of the flow channel model a can be selectively arranged according to a pre-designed flow channel, for example, a groove-shaped structure form with the shape of snake shape, spiral shape, F shape, W shape and the like is adopted. The runner pattern a is used to contact the metal slab 20 when the pressure-bearing form 10 is spaced apart from the metal slab 20 in parallel, so that the metal slab 20 can be supported on the upper side of the pressure-bearing form 10, and a certain distance is formed between the metal slab 20 and the runner pattern a to allow for deformation of a portion of the metal slab 20 located at the periphery of the runner pattern a.
And 102, pressing the metal plate blank 20 against the pressure-bearing template 10 at a high speed under the action of electromagnetic induction, and realizing the contact die attachment of the metal plate blank 20 and the pressure-bearing template 10.
Referring to fig. 3 and 6, an electromagnetic pulse generator is provided by the components of the discharge coil 30, the capacitor 40, the switch 50, the power supply 60, and the associated charge/discharge management circuit; the power source 60 may be a 220V ac power source, one end of the discharge coil 30 is connected to the switch 50 through the power source 60, the other end of the discharge coil 30 is directly connected to the switch 50, and the capacitor 40 is connected in parallel to the power source 60 through the charge and discharge management circuit. In this way, the discharge coil 30 may be placed on the side of the metal slab 20 away from the pressure-bearing die plate 10 in advance, so that the discharge coil 30 is directly opposite to the metal slab 20, and the discharge coil 30 and the metal slab 20 are vertically distributed in parallel at a certain interval distance.
Before the switch 50 is closed (or turned on), the capacitor 40 is charged to saturation using the power supply 60, and then closes (or turns on) the switch 50, so that the capacitor 40 instantaneously discharges the discharge coil 30, thereby forming a varying pulse excitation current in the discharge coil 30 and then forming a strong magnetic field around the discharge coil 30, which, according to the principle of electromagnetic induction, the strong magnetic field causes the discharge coil 30 to generate eddy currents (i.e. induced currents in opposite directions) near the surface side of the metal slab 20, thereby forming another pulse magnetic field, the two electromagnetic fields with opposite directions generate electromagnetic repulsion force (i.e. electromagnetic force), the repulsive magnetic force (i.e., electromagnetic force) drives a partial region (i.e., a region spaced from the pressure-bearing formwork 10) of the metal slab 20 to move, so that the metal slab is pressed against and attached to the pressure-bearing formwork in a full-face manner, and the metal slab is deformed at a high speed.
Specifically, in the embodiment that the flow channel model a is a convex structure, because the portion of the metal slab 20 in contact with the flow channel model a has no interval or the distance of the interval does not satisfy the condition that the metal slab 20 deforms under the action of electromagnetic induction, the region of the metal slab 20 located at the periphery of the flow channel model a can perform height motion towards the direction of the plane portion b of the pressure-bearing template 10 under the pushing of electromagnetic force, so that after the local region of the metal slab 20 deforms, a flow channel cavity structure aligned with the flow channel model a can be punched on the metal slab 20; based on the same principle, in the embodiment that the flow channel model a is a concave structure, because the portion of the metal slab 20 in contact with the planar portion a has no interval or the distance of the interval does not satisfy the condition that the metal slab is deformed under the action of electromagnetic induction, the region of the metal slab 20 corresponding to the flow channel model a moves at a high speed towards the concave space of the flow channel model a under the pushing of the electromagnetic force, so that the local region of the metal slab 20 is deformed, and the corresponding flow channel cavity structure is punched.
It should be noted that: the metal plate blank 20 is preferably made of a high-conductivity material such as copper, copper alloy, aluminum alloy, magnesium alloy, or the like; the pressure-bearing template 10 is preferably made of materials with poor conductivity and high strength or hardness, such as tool steel, cold-punching die steel and the like; so as to prevent the pressure-bearing die plate 10 from generating negative influence on the electromagnetic field formed between the discharge coil 30 and the metal plate blank 20 by using the material performance difference between the metal plate blank 20 and the pressure-bearing die plate 10.
In one embodiment, to ensure the effectiveness of the electromagnetic force, the distance d between the discharge coil 30 and the metal plate blank 20 is preferably controlled within 1 ± 0.5 mm.
And 103, separating the metal plate blank 20 from the pressure-bearing template 10 to finish the forming processing of the metal plate blank 20.
Referring to fig. 5, after the metal slab 20 and the pressure-bearing template 10 are contacted and attached to each other, the switch 50 is turned off, the metal slab 20 is separated from the pressure-bearing template 10, so that the metal slab 20 with the runner cavity structure can be obtained, and after the metal slab 20 is subjected to subsequent processing by technological means such as cutting and polishing, the upper-layer liquid-cooled plate can be formed.
First, compared with a punching machine and a convex die head and a concave die head thereof adopted in the traditional die punching method, the pressure-bearing template 10 is lower in manufacturing cost and more diversified in structural design, and when a preset runner structure is changed, only one part of the pressure-bearing template 10 which is matched with the part needs to be replaced or configured, so that the configuration and use cost of related matched dies can be effectively reduced in the forming and processing process of the liquid-cooled plate. Secondly, the electromagnetic pulse technology is adopted, so that the forming speed and the forming quality of the liquid cooling plate can be improved, the method is more suitable for clean processing production, and favorable conditions are created for improving the processing efficiency because only the pressure-bearing template 10 needs to be matched, replaced and adjusted.
Referring to fig. 3, 4 and 5, in some embodiments, according to the structural configuration of the runner model a on the metal slab 10, an exhaust hole c may be formed on the runner model a or the planar portion b; wherein, under the embodiment that the flow channel model a adopts a concave structure, the exhaust hole c is arranged in the flow channel model a; in the embodiment of the flow channel model a with a convex structure, the exhaust hole c is opened on the plane part b. In the process that the metal plate blank 20 and the pressure-bearing template 10 deform due to contact with the die, air existing between the metal plate blank and the pressure-bearing template often generates resistance after compression, so that the contact between the metal plate blank and the pressure-bearing template is prevented; therefore, the air between the metal plate blank 20 and the pressure-bearing template 10 can be smoothly discharged by the arranged exhaust holes c, so that the smooth operation of contact die attachment can be ensured, and favorable conditions can be created for improving the forming precision of the metal plate blank 20. In order to ensure the surface quality of the molded metal slab 20, the diameter of the vent hole c should be as small as possible, preferably 1mm or less.
Referring to fig. 3, 4 and 5, in one embodiment, the vent hole c is preferably located in the area where the metal slab 20 and the pressure bearing formwork 10 finally contact the formwork; due to the non-uniformity of the electromagnetic field distribution, the metal plate blank 10 cannot uniformly bear the pressure of the template 10 to be pressed and contacted; therefore, the air between the upper layer liquid cooling plate and the lower layer liquid cooling plate flows along the area contacting the sticking die in sequence, namely the air flows from the area contacting the sticking die firstly to the area contacting the sticking die secondly, and the air can be exhausted finally by utilizing the exhaust holes c arranged in the area, the arrangement number of the exhaust holes c can be reduced to the maximum extent, the distribution area of the exhaust holes c can be reduced, and favorable conditions are created for enhancing the surface quality of the final upper layer liquid cooling plate. Taking the runner model a as a concave structure as an example, the exhaust holes c may be provided on the bottom surface of the runner model a and communicate the concave space with the space of the pressure-bearing die plate 10 on the side away from the metal slab 20.
The present invention has been described in terms of specific examples, which are provided to aid understanding of the invention and are not intended to be limiting. For a person skilled in the art to which the invention pertains, several simple deductions, modifications or substitutions may be made according to the idea of the invention.
