Description

Technical Field

[0001] This application relates to the field of battery manufacturing equipment technology, and more specifically, to a shaping device. Background Technology

[0002] In the manufacture of battery pack covers or other tray products for new energy vehicles, compression molding is typically used. After molding, the battery pack cover or other tray product is usually removed from the mold and then shaped.

[0003] Current shaping methods typically involve static shaping, where the workpiece after demolding is placed on a machine or table to stand and shape. This process lacks mold shaping and pressure shaping, resulting in long standing times and poor shaping effects. Utility Model Content

[0004] In view of the above-mentioned shortcomings, this application provides a shaping device that can place the workpiece after demolding into a conformal die that matches the shape of the workpiece, and use a pressing mechanism to press and shape the circumferential edge of the workpiece, thereby improving the shaping quality and shaping efficiency.

[0005] This application is implemented as follows:

[0006] An example of this application provides a shaping apparatus for pressing and shaping a workpiece. The shaping apparatus includes a frame and a pressing mechanism. A conformal die is disposed on the frame, the conformal die having a receiving cavity for placing and fitting the workpiece. The pressing mechanism includes a drive member, multiple pressure plates, and multiple connecting arms. Each pressure plate is connected to at least one end of a connecting arm, and the multiple connecting arms are spaced apart around the circumferential edge of the conformal die and rotatably connected to the frame. The drive member is disposed on the frame and connected to the end of each connecting arm away from the pressure plate. The drive member can selectively drive the multiple connecting arms to rotate so that the multiple pressure plates press against the circumferential edge of the workpiece.

[0007] Because the dimensions of workpieces such as battery pack covers or other tray products obtained by compression molding vary significantly at their edges, they often require rounded transitions or reinforcing ribs. Furthermore, due to thermal expansion and contraction during compression molding, the pressing effect on the workpiece edges is often poor after demolding. Therefore, this application provides a molding apparatus that, during workpiece shaping, places the workpiece in a conformal die, which limits the workpiece's position. Then, a driving component drives the connecting arms to rotate, pressing multiple pressure plates connected to the connecting arms against the four perimeters of the workpiece. The conformal die can restrict the shape and size of the workpiece during the pressing and shaping process, improving the shaping quality and efficiency of the workpiece edges when using pressure plates to press and shape the four perimeters. Furthermore, each pressure plate in the shaping device is individually connected by multiple connecting arms, and the multiple pressure plates can be individually flipped at different positions in the circumferential direction of the conforming die. Compared with connecting multiple pressure plates into an integral frame and using a driving component to drive the connecting arms to flip the integral frame, the rotation amplitude of the pressing mechanism in this application embodiment is smaller, thereby reducing the space occupancy rate of the shaping device during operation.

[0008] In conjunction with the first aspect, in one alternative embodiment, the connecting arm is bent and has staggered first and second connecting segments, and a hinged segment located between the first and second connecting segments. The hinged segment is hinged to the frame, a pressure plate is disposed on the first connecting segment, and a drive member is connected to the second connecting segment. The drive member can selectively drive multiple second connecting segments to rotate so that the pressure plate connected to the first connecting segment presses against the circumferential edge of the workpiece.

[0009] In the above implementation process, when it is necessary to press and shape the workpiece within the conformal die, the driving component can be used to push the second connecting section, causing the second connecting section to rotate around the hinge section. This, in turn, causes the first connecting section and the pressure plate disposed on the first connecting section to rotate, so that the pressure plate presses against the four edges of the workpiece, thus shaping the workpiece. Setting the connecting arm in a bent shape facilitates the driving component to drive the second connecting section of the connecting arm to rotate and reduces the space occupancy of the entire connecting arm during rotation.

[0010] In conjunction with the first aspect, in an alternative implementation, the drive member may selectively drive the second connecting segment to flip so that the first connecting segment is located outside the circumferential edge of the conformal die.

[0011] In the above implementation process, before and after pressing, the driving member can drive the second connecting segment to rotate around the hinge segment, so that the first connecting segment connected to the hinge segment flips to outside the circumferential edge of the conformal die, so as to put the workpiece into the conformal die or take out the workpiece from the conformal die.

[0012] In conjunction with the first aspect, in an alternative embodiment, each pressure plate is connected to a first connecting segment of at least two connecting arms, and the first connecting segments of the two connecting arms are located at both ends of the pressure plate.

[0013] In the above implementation process, a connecting arm is connected to each end of each pressure plate. When the workpiece is pressed and shaped, multiple connecting arms press against the pressure plate together, which can make the pressure of the pressure plate on the workpiece more uniform and improve the problem of poor workpiece shaping quality caused by pressure plate warping and deformation.

[0014] In conjunction with the first aspect, in one alternative implementation, among a plurality of connecting arms connected to the same pressure plate, a plurality of second connecting segments are connected to the drive member via connecting beams.

[0015] In the above implementation process, when multiple connecting arms are used to connect the same pressure plate, the multiple second connecting segments of the multiple connecting arms connected to the same pressure plate are connected into a whole by connecting beams, so that the driving component can simultaneously drive the multiple connecting arms to rotate through the connecting beams, thereby improving the rotation consistency of the multiple connecting arms, improving the pressure uniformity of the pressure plate on the edge of the workpiece, and thus improving the shaping quality.

[0016] In conjunction with the first aspect, in one alternative embodiment, the drive unit includes a plurality of telescopic cylinders, each of which is hinged to a plurality of connecting beams in a corresponding manner.

[0017] In the above implementation process, a telescopic cylinder is connected to each connecting beam, and the movable end of the telescopic cylinder is hinged to the connecting beam. Therefore, the telescopic movement of the telescopic cylinder can push the connecting beam to rotate, thereby driving the second connecting section connected to the connecting beam to rotate, so that the first connecting section drives the pressure plate to rotate and press against the edge of the workpiece.

[0018] In conjunction with the first aspect, in an optional embodiment, a mounting frame is provided on the side of the frame away from the conformal die, the mounting frame and the conformal die are spaced apart, and a telescopic cylinder is provided on the mounting frame, the telescopic cylinder selectively causing the connecting beam to extend into the gap between the mounting frame and the conformal die.

[0019] In the above implementation process, the telescopic cylinder is set on the mounting frame on the back of the conformal die. This not only makes it easier for the telescopic cylinder to drive the connecting beam to rotate so that the connecting arm can press the pressure plate against the edge of the workpiece, but also allows the telescopic cylinder to telescopically move on the back of the conformal die. When pressing is not required, the connecting beam can extend into the gap between the mounting frame and the conformal die, thereby reducing the space occupancy rate of the entire shaping device during operation.

[0020] In conjunction with the first aspect, in one optional embodiment, at least one edge of the workpiece is stepped, having a first stepped surface and a second stepped surface. A pressure plate corresponding to the stepped edge includes a first pressure plate and a second pressure plate. A connecting arm has a protrusion corresponding to the position of the first pressure plate, with the first pressure plate disposed on the protrusion and the second pressure plate disposed on the connecting arm. A driving member drives the connecting arm to rotate so that the first pressure plate abuts against the first stepped surface and the second pressure plate abuts against the second stepped surface.

[0021] In the above implementation process, when the edge of the workpiece has two stepped pressing surfaces with uneven heights, the pressure plate can be divided into a first pressure plate and a second pressure plate. A protrusion is set at the position of the connecting arm corresponding to the first pressure plate. The first pressure plate is set at the protrusion, and the second pressure plate is set at the connecting arm, so that there is a certain height difference between the first pressure plate and the second pressure plate. When the driving component drives the connecting arm to rotate, the first pressure plate can press against the first step surface, and at the same time, the second pressure plate can press against the second step surface, thereby pressing and shaping the stepped edge of the workpiece.

[0022] In conjunction with the first aspect, in one optional embodiment, the workpiece has a quadrilateral groove structure, and flanges are provided around the groove opening. A conformal die cavity is used to accommodate the groove, and the flanges overlap the circumferential outer wall of the conformal die corresponding to the opening of the cavity. A second step surface is located on the flange, and a first step surface is located at the bottom of the groove structure.

[0023] In the above implementation process, when the workpiece is a quadrilateral groove structure with flanges on all four sides, the receiving cavity of the conforming die can be set to fit the shape of the groove structure, and the circumferential outer wall of the conforming die corresponding to the opening of the receiving cavity overlaps with the flange. When the pressure plate presses and shapes the four sides of the workpiece, the receiving cavity can limit the shape and size of the groove to prevent the groove from being deformed by pressing. In addition, the circumferential outer wall of the conforming die can support the flange of the groove structure, so that the pressure plate can press the flange more evenly, thus improving the problem of flange deformation during pressing.

[0024] In conjunction with the first aspect, in one optional embodiment, the workpiece has two sets of adjacent first and second sides, the length of the second side being greater than the length of the first side. A pressing mechanism is provided with two pressure plates corresponding to the positions of the second sides and one pressure plate corresponding to the positions of the first sides. Each pressure plate is connected to at least one connecting arm. A driving member can selectively drive multiple connecting arms to rotate so that multiple pressure plates press against the two sets of first and second sides.

[0025] In the above implementation process, when the lengths of two adjacent sides of a workpiece with a quadrilateral groove structure are inconsistent, in order to improve the shaping quality of the longer side, two pressure plates are set at the position of the pressing mechanism corresponding to the second side. The two pressure plates can be pressed against the second side of the workpiece by the corresponding connecting arm driven by the driving component. Attached Figure Description

Detailed Implementation

[0033] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this application; the terms “comprising” and “having”, and any variations thereof, in the specification and the foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0035] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0036] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0037] Because the dimensions of the edges of workpieces such as battery pack covers or other tray products obtained by compression molding vary considerably, rounded transitions or reinforcing ribs are often incorporated. Furthermore, due to thermal expansion and contraction during compression molding, the edges of the workpiece are not well-pressed after demolding. If the workpiece is left to stand still after demolding, the setting time is long, and the workpiece is prone to deformation during the setting process, resulting in poor setting quality.

[0038] Therefore, this application provides a shaping device 1, please refer to... Figure 1 and Figure 2 The shaping device 1 includes a frame 10 and a pressing mechanism 30. A conformal die 20 is mounted on the frame 10, having a receiving cavity 21 for placing and fitting the workpiece 2. The pressing mechanism 30 includes a drive member 31, multiple pressure plates 32, and multiple connecting arms 33. Each pressure plate 32 is connected to at least one end of a connecting arm 33. The multiple connecting arms 33 are spaced apart around the circumferential edge of the conformal die 20 and rotatably connected to the frame 10. The drive member 31 is mounted on the frame 10 and connected to the end of each connecting arm 33 away from the pressure plate 32. The drive member 31 can selectively drive the multiple connecting arms 33 to rotate so that the multiple pressure plates 32 press against the circumferential edge 201 of the workpiece 2.

[0039] When shaping the workpiece 2 using the forming apparatus provided in this application embodiment, the workpiece 2 can be placed in the receiving cavity 21 of the conformal die 20, and the conformal die 20 can limit the workpiece 2. Then, the driving member 31 drives the connecting arm 33 to rotate, so as to press the multiple pressure plates 32 connected to the multiple connecting arms 33 against the four peripheral parts 201 of the workpiece 2.

[0040] The conformal die 20 can restrict the shape and size of the workpiece 2. When the pressure plate 32 is used to press and shape the four peripheral parts 201 of the workpiece 2, it can avoid the problem of deformation of the edges 201 of the workpiece 2 caused by the pressure plate 32, thus improving the shaping quality of the workpiece 2. Moreover, compared with conventional static shaping, pressing with the pressure plate 32 can also improve the shaping efficiency.

[0041] In addition, each pressure plate 32 in the shaping device 1 is individually connected by multiple connecting arms 33. The multiple pressure plates 32 can be individually flipped at different positions in the circumferential direction of the conformal die 20. Compared with connecting multiple pressure plates 32 into an integral frame and using the driving member 31 to drive the connecting arms 33 to flip the integral frame, the rotation amplitude of the pressing mechanism 30 in this embodiment is smaller, thereby reducing the space occupancy rate of the entire shaping device 1 during the working process.

[0042] The following describes in further detail, with reference to the accompanying drawings, the frame 10, the conformal die 20, and the pressing mechanism 30 in the shaping device 1 provided in the embodiments of this application.

[0043] The frame 10 supports the conformal die 20 and the pressing mechanism 30, providing a mounting position for them to ensure a relatively stable positional relationship. This application does not limit the specific structure of the frame 10. In some embodiments, the frame 10 is provided with a mounting platform for fixing the conformal die 20. Four legs are provided below the mounting platform to support it.

[0044] Furthermore, in some embodiments, for ease of installation of the pressing mechanism 30, see further... Figure 2 , Figure 3 , Figure 4 and Figure 5 Alternatively, a mounting frame 11 can be provided below the mounting platform. The mounting frame 11 and the conformal die 20 are spaced apart to form a certain gap, allowing the drive component 31 to be mounted on the mounting frame 11, thus reducing the space occupancy of the entire shaping device 1. It is understood that the drive component 31 needs to drive the connecting arm 33 to rotate, and the mounting frame 11 will not interfere with the rotation of the connecting arm 33. In some embodiments, the mounting frame 11 includes multiple longitudinally and transversely arranged support beams, the ends of which are connected to the four legs of the frame 10.

[0045] Furthermore, to facilitate the circumferentially spaced arrangement of multiple connecting arms 33 around the conformal die 20 on the frame 10 and to enable the connecting arms 33 to be rotatably connected to the frame 10, in some embodiments, multiple hinge seats can be provided on the circumferential sidewall of the mounting platform. Each hinge seat includes two spaced-apart mounting plates that protrude outwards circumferentially toward the conformal die 20. The two mounting plates have opposing through holes for the hinge shaft to pass through. The connection between the hinge shaft and the through holes enables the rotatable connection between the connecting arms 33 and the machine platform.

[0046] The conformal die 20 refers to a die whose shape is consistent with the shape of the workpiece 2 to be shaped. When the workpiece 2 is placed in the receiving cavity 21 of the conformal die 20, the receiving cavity 21 can fit the workpiece 2. This application does not limit the specific shape of the conformal die 20, and it can be adjusted accordingly according to the shape of the workpiece 2 to be shaped.

[0047] As an example, when workpiece 2 is a quadrilateral groove structure and the groove opening is surrounded by flanges, please refer to... Figure 1 and Figure 2 The receiving cavity 21 of the conformal groove can be configured as a quadrilateral structure, and the depth of the receiving cavity 21 is consistent with the height of the workpiece 2. The flange of the workpiece 2 can overlap the circumferential outer wall of the conformal groove corresponding to the opening of the receiving cavity 21. When the pressure plate 32 is used to press and shape the edge 201 around the bottom of the groove of the workpiece 2, the receiving cavity 21 can restrict the shape and size of the groove structure to prevent deformation of the groove structure. When the pressure plate 32 is used to press and shape the flange of the workpiece 2, the circumferential outer wall of the conformal die 20 corresponding to the opening of the receiving cavity 21 can support the flange and reduce the deformation of the flange.

[0048] Furthermore, in some embodiments, to facilitate further definition of the size and shape of the flange, the conformal die 20 can be configured as a stepped groove structure, and the receiving cavity 21 includes a first chamber and a second chamber that are interconnected. The shape of the first chamber is consistent with the groove structure of the workpiece 2, and it is used to receive the groove of the workpiece 2. The shape of the second chamber is consistent with that of the flange, and it is used to receive the flange.

[0049] This application does not limit the workpiece 2 to a quadrilateral groove structure with flanges. In some embodiments, the workpiece 2 can also be a circular plate structure or a cylindrical structure with flanges.

[0050] This application does not limit how the conformal die 20 is set on the frame 10. In some embodiments, mounting holes can be provided at the machine base of the frame 10, and the conformal die 20 can be embedded in the mounting holes of the machine base.

[0051] The pressing mechanism 30 is provided with multiple pressure plates 32, each pressure plate 32 is connected to at least one connecting arm 33, and the multiple connecting arms 33 are spaced apart around the circumferential edge of the conformal die 20 and are rotatably connected to the frame 10 so that the multiple connecting arms 33 can be selectively driven to flip by the driving member 31 so that the multiple pressure plates 32 press against the circumferential edge 201 of the workpiece 2 to shape the workpiece 2.

[0052] It is understood that this application does not limit the shape or size of each pressure plate 32, and the number of pressure plates 32 can be selected as needed, as long as multiple pressure plates 32 can press against the workpiece 2 around the circumferential edge 201. For example, when the edge 201 of the workpiece 2 is quadrilateral, multiple pressure plates 32 can be enclosed to form a quadrilateral to press against the quadrilateral edge 201 of the workpiece 2. As another example, when the edge 201 of the workpiece 2 is a pentagonal ring structure, multiple pressure plates 32 can be enclosed to form a pentagonal ring structure to press against the pentagonal ring edge 201 of the workpiece 2. As yet another example, when the edge 201 of the workpiece 2 is a circular ring structure, multiple pressure plates 32 can be enclosed to form a circular ring structure to press against the circular ring edge 201 of the workpiece 2.

[0053] Furthermore, when the edge 201 of workpiece 2 has multiple pressing surfaces of different heights, multiple pressing plates 32 can be provided opposite to the edge 201. For example, when workpiece 2 is a quadrilateral groove structure with flanges, please refer to [reference needed]. Figure 4 The workpiece 2 of the groove structure has four edges 201 in different directions, namely two sets of adjacent first edges 202 and second edges 203. Each edge 201 is stepped, including a second stepped surface 205 at the flange and a first stepped surface 204 at the bottom wall of the groove, the first stepped surface 204 being lower than the second stepped surface 205. Accordingly, the pressure plate 32 at the connecting arm 33 corresponding to the edge 201 can be set as a first pressure plate 321 and a second pressure plate 322. A protrusion 335 can be provided at the position of the connecting arm 33 corresponding to the first pressure plate 321, the first pressure plate 321 is placed on the protrusion, and the second pressure plate 322 is placed on the connecting arm 33, so that there is a height difference between the first pressure plate 321 and the second pressure plate 322, which is consistent with the height difference between the first stepped surface 204 and the second stepped surface 205. Therefore, please refer to Figure 2 When the driving member 31 drives the connecting arm 33 to rotate, it can press the first pressure plate 321 against the first step surface 204, and at the same time press the second pressure plate 322 against the second step surface 205.

[0054] If each edge 201 has more stepped surfaces, more pressure plates 32 of different heights can be provided at the connecting arm 33 corresponding to the edge 201.

[0055] Furthermore, when the workpiece 2 includes two sets of adjacent first side portions 202 and second side portions 203, and the second side portion 203 is longer than the first side portion 202, multiple pressure plates 32 can be provided at the location corresponding to the second side portion 203, and each pressure plate 32 is connected to at least one connecting arm 33. Therefore, the driving member 31 can drive the multiple pressure plates 32 at the multiple connecting arms 33 to press against the second side portion 203.

[0056] Of course, this application does not limit the second side 203 to be pressed by only two pressure plates 32. For example, only one long pressure plate 32 can be set at the second side 203, or the second side 203 can be pressed by three pressure plates 32. The first side 202 can also be pressed by one pressure plate 32 or by multiple pressure plates 32, as long as the multiple pressure plates 32 can surround and press the four sides 201 of the workpiece 2.

[0057] This application does not limit the specific structure of the connecting arm 33. In some embodiments, please refer to [link to relevant documentation]. Figure 2 , Figure 3 , Figure 4 and Figure 5 The connecting arm 33 is bent and has staggered first connecting segments 331 and second connecting segments 332, as well as a hinge segment 333 located between the first connecting segments 331 and the second connecting segments 332. The hinge segment 333 is hinged to the frame 10. A pressure plate 32 is disposed on the first connecting segment 331, and a drive member 31 is connected to the second connecting segments 332. The drive member 31 can selectively drive multiple second connecting segments 332 to rotate so that the pressure plate 32 connected to the first connecting segment 331 presses against the circumferential edge 201 of the workpiece 2.

[0058] By setting the connecting arm 33 in a bent shape, the length of the connecting arm 33 can be reduced, and the rotation space occupied by the connecting arm 33 can be reduced when the driving component 31 drives the connecting arm 33 to rotate.

[0059] This application does not limit how the hinge segment 333 is hinged to the frame 10. In some embodiments, the end of the hinge segment 333 facing the inner corner may be provided with a through hole. The hinge segment 333 is inserted between two mounting plates disposed at the machine base, and a rotating shaft passes sequentially through the mounting plate and the through hole at the hinge segment 333, allowing the hinge segment 333 to rotate relative to the mounting plate around the hinge shaft. Please refer to [link to relevant documentation]. Figure 2 and Figure 3 When the driving member 31 drives the connecting arm 33 to rotate so as to press the pressure plate 32 against the circumferential edge 201 of the workpiece 2, the first connecting section 331 is approximately parallel to the pressing surface of the workpiece 2, and the second connecting section 332 is approximately perpendicular to the pressing surface of the workpiece 2.

[0060] Furthermore, in some embodiments, after pressing and setting, please refer to [the documentation / reference]. Figure 4 and Figure 5 ( Figure 5 (Driver 31 omitted). Driver 31 can selectively drive the second connecting segment 332 to flip so that the first connecting segment 331 is outside the circumferential edge of the conformal die 20. At this time, the first connecting segment 331 is located approximately vertically outside the circumferential edge of the conformal die 20, and the second connecting segment 332 is flipped to the underside of the conformal die 20. Flipping the first connecting segment 331 outside the circumferential edge of the conformal die 20 facilitates the placement of the workpiece 2 into the conformal die 20 or the removal of the workpiece 2 from the conformal die 20.

[0061] Furthermore, in some embodiments, please continue to refer to Figures 1-5 Each pressure plate 32 can be connected to two connecting arms 33. The two first connecting segments 331 of the two connecting arms 33 are respectively connected to the two ends of the pressure plate 32, and the two second connecting segments 332 are connected by a connecting beam 334. The driving member 31 is connected to the connecting beam 334 so that the driving member 31 can drive the connecting beam 334 to rotate, thereby causing the two connecting arms 33 to rotate, and together causing the pressure plate 32 to press against the edge 201 of the workpiece 2.

[0062] Furthermore, this application does not limit the specific type of the driver 31; in some embodiments, please refer to [reference needed]. Figure 3 The driving component 31 includes multiple telescopic cylinders, which are mounted on the mounting bracket 11 and are hinged to multiple connecting beams 334 one by one. The telescopic cylinders push the connecting beams 334 to rotate by extending and retracting, thereby causing the connecting arm 33 and the pressure plate 32 connected to the connecting arm 33 to flip.

[0063] As an example, a protruding connecting plate is provided on the side of the connecting beam 334 facing the telescopic cylinder in the middle, and a U-shaped clamp is provided on the movable end of the telescopic cylinder. The connecting plate is inserted into the U-shaped clamp, and the rotating shaft passes through the through holes of the U-shaped clamp and the connecting plate in sequence to realize the hinge connection between the telescopic cylinder and the connecting beam 334.

[0064] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
