Technical Field

[0001] This invention relates to the technical field of molding equipment, and in particular to a battery conductive sheet molding and processing equipment and its molding process. Background Technology

[0002] Battery conductive plates are conductive metal strips on batteries used for connecting to other electrical devices. To facilitate connection, conductive plates come in various shapes, such as... Figure 12 The conductive sheet structure shown is mainly used in battery storage devices in the field of solar power generation. The conductive sheet is right-angled, with a spherical protrusion on one right-angled face and an opening in the center of the spherical protrusion. The right-angled face has two inclined side wings, and a window is opened on the other right-angled face. A right-angled retaining plate is installed in the window, and the front and back sides of the right-angled retaining plate are vertically provided with retaining edges. In traditional processing methods, conductive sheets of this shape generally need to undergo multiple bending and stamping processes. Due to its complex shape, the processing steps are long and the process is cumbersome.

[0018] Preferably, the top of the pressure plate is Z-shaped, and the lateral width of the pressure plate is greater than the width of the placement groove, so that the pressure plate can contact the top of the mold support table.

[0022] The present invention provides a molding process for a battery conductive sheet, comprising the following steps:

[0023] a. Insert the conductive sheet blank between the top of the mold support table and the pressure plate along the top surface of the mold support table. With the help of the inclined surface on the pressure plate, the blank can be inserted smoothly. The two pressure plates and one positioning plate can be used to position and pre-fix the conductive sheet.

[0024] b. The pressure mold table is pushed down by the hydraulic cylinder. The bottom of the pressure mold table contacts the blank and pushes the support mold table down through the blank. The elastic reset mechanism deforms. When the blank moves to the top position of the side plate, the bottom edge of the pressure mold table squeezes the blank, so that the blank bends and deforms on the side plate. At this time, the initial deformation of the blank is achieved.

[0025] c. As the mold support table moves down, the limiting post contacts the right-angle base plate. At this time, the pressure plate stops moving and separates from the mold support table.

[0026] d. The pressing platform continues to move down, and the top of the top column and the top of the mold column gradually extend to the outside of the mold support platform. The top column squeezes the blank on it into the spherical mold groove, and the inclined plate squeezes the blank placed at the top of the groove onto the mold column. At this time, the blank achieves two-stage deformation.

[0027] e. The corner plate is moved by the first cylinder. The corner plate moves the horizontal column laterally and the punch rod downward. The bottom of the punch rod punches the blank in the spherical mold groove. The horizontal column drives the push plate to move synchronously through the locking mechanism. The push plate presses the blank on it into the through hole and fits with the baffle. The unlocking mechanism unlocks the locking mechanism. At this time, the end of the horizontal column squeezes the blank on it through the gap between the inner wall of the through hole and the side wall of the baffle, thereby realizing the three-stage deformation of the blank. At this time, the blank is formed.

[0028] f. The first cylinder pushes the horizontal column and push plate to reset, the push cylinder pulls the pressure mold table upward in the opposite direction, and the second cylinder is controlled to extend. The extended end of the second cylinder contacts the protrusion and presses the mold support table so that it cannot move. At this time, the mold support table separates from the pressure mold table and the blank is taken out.

[0029] g. The second cylinder gradually contracts, and the mold support table is gradually reset through the elastic reset mechanism.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows: by adopting a continuous processing and one-time molding method to form the conductive sheet into a specified shape, the processing steps can be greatly reduced, the processing of the conductive sheet can be simplified, and a rapid prototyping processing method can be achieved, which effectively improves the processing efficiency, simplifies the processing method, and saves the cost and manpower investment required by the traditional method of using multiple machines to cooperate in processing.

[0045] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0046] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0047] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0048] like Figures 1 to 11 As shown, a battery conductive sheet forming and processing equipment of the present invention includes a pressing mold structure 1 and a supporting mold structure 2 distributed vertically.

[0049] The molding structure 1 includes a molding platform 3, a spherical mold groove 4 is provided at the middle of the bottom of the molding platform 3, a punch 5 is vertically slidably inserted in the middle of the molding platform 3, inclined plates 6 are provided on the front and rear side walls of the molding platform 3, two horizontal columns 7 are arranged horizontally on the molding platform 3, the two horizontal columns 7 are distributed in a front and rear manner, the horizontal columns 7 pass through the molding platform 3 and are slidably connected to each other, a groove is provided on the side wall of the molding platform 3, a push plate 8 is provided in the groove, and the bottom of the push plate 8 is coplanar with the bottom of the molding platform 3;

[0050] The mold support structure 2 includes a mold support platform 9. A through hole 10 is vertically opened in the middle of the mold support platform 9. A top post 11 is slidably arranged in the through hole 10. The top of the top post 11 is spherical and a material hole is vertically opened in the middle of the top post 11. Placement grooves 12 are opened on the front and rear side walls of the mold support platform 9. The top of the placement groove 12 extends to the top of the mold support platform 9. A mold post 13 is slidably arranged in the placement groove 12. The top of the mold post 13 is inclined. A side plate 14 is slidably contacted on the outer side wall of the mold support platform 9. The side plate 14 is located between the two placement grooves 12. An opening 15 is opened in the middle of the side plate 14. A baffle 16 is vertically arranged in the middle of the opening 15.

[0051] Specifically, the spherical mold groove 4 corresponds to the position of the top pillar 11, the punch 5 corresponds to the position of the material hole on the top pillar 11, the mold column 13 corresponds to the position of the inclined plate 6, the position of the horizontal column 7 corresponds to the position of the gap between the side wall of the baffle 16 and the inner wall of the through 15, and the position of the push plate 8 corresponds to the position of the baffle 16.

[0052] In use, the blank cut to the specified shape is placed on top of the mold support table 9, and the pressing mold structure 1 is pushed downward to press the blank. The position of the top post 11 is fixed. At this time, the ground of the pressing mold table 3 contacts the blank and pushes the mold support table 9 downward through the blank. The mold support table 9 slides relative to the side plate 14. When the blank moves to the top position of the side plate 14, the bottom of the pressing mold table 3 pushes the blank to bend on the side plate 14, so that the blank is bent into a right angle shape. Then the pressing mold table 3 continues to move downward, and the top of the mold post 13 gradually extends to the outside of the placement groove 12 and contacts the blank. The inclined plate 6 presses the blank onto the mold post 13. Because the top of the mold post 13 is inclined, the blank at this position is bent into an inclined state. At the same time, the top post 11 gradually extends to the outside of the through hole 10. The spherical surface of the top of the top post 11 presses the blank on the top post 11 into the spherical mold groove 4. This causes the blank at that position to form a spherical shape, pushing the punch 5 downwards. The punch 5 cuts a round hole in the center of the spherical blank, and the cut-off tail material enters the material hole in the center of the top column 11 and is discharged through the bottom of the material outlet. At the same time, the bottom of the punch 5 is inserted into the material hole. At this time, the pressure plate 3 and the support plate 9 stop moving, pushing the horizontal column 7 and the push plate 8 to move laterally. The horizontal column 7 and the push plate 8 both enter the through 15, and the push plate 8 presses the blank onto the baffle 16, so that the blank achieves right-angle deformation in the through 15, realizing the deformation of the right-angle clamping plate on the conductive sheet. At the same time, the two horizontal columns 7 squeeze and push the blank between the side wall of the baffle 16 and the inner wall of the through 15 to the right, so that the blank at this position bends and deforms and is fastened onto the baffle 16, realizing the deformation of the two clamping edges on the right-angle clamping plate. Thus, the one-time forming process of the conductive sheet is realized.

[0053] During unloading, since part of the formed conductive sheet is stuck in the opening 15, it is necessary to keep the position of the mold support 9 still and move the pressure mold 3 upward so that the conductive sheet can be removed.

[0054] In actual use, in order to avoid the bottom edge of the pressing table 3 cutting off the blank on the side plate 14, the top of the side plate 14 can be set as an arc surface to facilitate the smooth deformation of the blank.

[0055] By adopting a continuous processing and one-time molding method to form conductive sheets into the specified shape, the processing steps can be greatly reduced, the processing complexity of conductive sheets can be reduced, and a rapid prototyping processing method can be achieved, which effectively improves processing efficiency, simplifies processing methods, and saves the cost and manpower investment required by the traditional method of using multiple machines to process.

[0056] Preferred, such as Figure 5 and Figure 7As shown, a locking mechanism is provided between the horizontal column 7 and the push plate 8. The locking mechanism is used to make the horizontal column 7 drive the push plate 8 to move. An unlocking mechanism is provided in the gap between the side wall of the baffle 16 and the inner wall of the through 15. The unlocking mechanism is used to unlock the locking mechanism to separate the horizontal column 7 from the push plate 8.

[0057] The locking mechanism includes slots on each side wall of the front and rear sides of the push plate 8. The side wall of the cross column 7 is provided with a plug 17. The plug 17 is slidably inserted into the cross column 7, and the sliding direction of the plug 17 is horizontal and perpendicular to the moving direction of the cross column 7. A first leaf spring 18 is connected between the plug 17 and the cross column 7. A wedge hole 19 is provided on the side wall of the plug 17 facing the end of the cross column 7. A process port 20 is provided at the end of the cross column 7.

[0058] The unlocking mechanism includes a support plate 21 fixed to the side wall of the side plate 14. The support plate 21 is provided with a rod 22, which slides through the support plate 21. One end of the rod 22 is set as an inclined surface, and the other end of the rod 22 is provided with a limit plate 23. A second leaf spring 24 is connected between the support plate 21 and the rod 22.

[0059] Specifically, in its natural state, the first leaf spring 18 pushes the insert block 17 into the slot on the push plate 8. At this time, when the horizontal column 7 moves, it can push the first leaf spring 18 to move synchronously via the insert block 17. The insert block 17 pushes the first leaf spring 18 into the through-hole 15, thereby causing the first leaf spring 18 to extrude and deform the blank. Simultaneously, as the insert block 17 gradually approaches the insert rod 22, the inclined end of the insert rod 22 is inserted into the wedge hole 19 through the process port 20. The inclined surface of the insert rod 22 contacts the inclined surface of the inner wall of the wedge hole 19, and the insert rod 22 pushes the insert block 17 into the horizontal column 7 through the inner wall of the wedge hole 19. Inside, the first leaf spring 18 undergoes elastic deformation, at which point the insert block 17 gradually pulls out of the slot. When the push plate 8 contacts the baffle 16, the insert block 17 disengages from the push plate 8, and the horizontal column 7 continues to move. The end of the horizontal column 7 squeezes and deforms the blank in the gap between the inner wall of the through-hole 15 and the side wall of the baffle 16 and passes through the gap. At this time, the end of the horizontal column 7 passes through the gap, and the horizontal column 7 can push the insert rod 22 to slide on the support plate 21 through the insert block 17. The second leaf spring 24 undergoes elastic deformation, and the limiting plate 23 can limit the position of the insert rod 22 on the support plate 21, thereby realizing the unlocking of the horizontal column 7 and the push plate 8.

[0060] When the horizontal column 7 moves in the opposite direction, the end of the horizontal column 7 passes through the gap and gradually approaches the push plate 8, and the insertion rod 22 gradually withdraws from the wedge hole 19. The insertion block 17 on the horizontal column 7 gradually gets into the slot on the push plate 8, so that the horizontal column 7 and the push plate 8 re-establish a locking state.

[0061] Preferred, such as Figure 5 As shown, the insert block 17 has a sub-plate 25 on its end face facing the push plate 8.

[0062] Specifically, when the insert block 17 separates from the push plate 8, the secondary plate 25 remains in the slot. At this time, the horizontal column 7 moves through the gap between the through-hole 15 and the baffle 16, and the horizontal column 7 drives the secondary plate 25 to move in the slot through the insert block 17. The secondary plate 25 gradually contacts the inner wall of the slot, thereby generating additional squeezing force on the push plate 8 again through the secondary plate 25, preventing the insert block 17 from completely separating from the push plate 8. Furthermore, by setting the secondary plate 25, it is convenient for the secondary plate 25 to contact the inner wall on the other side of the slot and push the push plate 8 to move synchronously in the opposite direction when the horizontal column 7 moves in the opposite direction. Thus, the secondary plate 25 realizes the limiting and guiding function of the insert block 17 and the push plate 8.

[0063] Preferred, such as Figures 2 to 3 As shown, it also includes a corner plate 26. One side wall of the corner plate 26 is vertical, and the other side wall of the corner plate 26 is inclined. The vertical side wall of the corner plate 26 is connected to the horizontal column 7, and a first cylinder 27 is connected between the vertical side wall of the corner plate 26 and the pressure mold table 3. A slider 28 is slidably provided on the inclined side wall of the corner plate 26 along the inclined direction. The slider 28 is fixedly connected to the top of the punch 5.

[0064] An arc-shaped frame 30 is fixed on the outer wall of the pressing table 3, and a propulsion cylinder 31 is provided on the top of the arc-shaped frame 30;

[0065] An auxiliary arm 29 is fixed on the inclined side wall of the corner plate 26, and the bottom of the auxiliary arm 29 is slidably mounted on the top of the pressing table 3.

[0066] Specifically, when the first cylinder 27 extends or retracts, the first cylinder 27 can drive the corner plate 26 to move synchronously. At this time, the vertical side wall of the corner plate 26 can directly push the horizontal column 7 to move, thereby providing horizontal power to the horizontal column 7. In addition, the inclined side wall of the corner plate 26 can push the punch 5 to move downward through the slider 28, thereby providing vertical pushing force to the punch 5 synchronously. The punch 5 pushes the slider 28 to slide on the inclined side wall of the corner plate 26 in the opposite direction.

[0067] By propelling the extension and retraction of the hydraulic cylinder 31, the pressure mold table 3 can be moved up and down, thereby providing a vertical driving force for the pressure mold structure 1.

[0068] By setting up the auxiliary arm 29, the inclined sidewall of the corner plate 26 can be easily guided and supported, preventing the inclined sidewall of the corner plate 26 from bending and deforming during movement, thus improving the strength of the equipment. The bottom of the auxiliary arm 29 can slide on the top of the pressing table 3.

[0069] Preferred, such as Figure 3 and Figure 10 As shown, the front and rear side walls of the pressing table 3 are provided with second cylinders 32, and the front and rear side walls of the mold support table 9 are provided with protrusions 33.

[0070] Specifically, after the conductive sheet is processed, the push cylinder 31 drives the pressing platform 3 to move upward. At this time, the second cylinder 32 extends and the extended end of the second cylinder 32 contacts the protrusion 33. Through the second cylinder 32 and the protrusion 33, the position of the support platform 9 can be fixed. At this time, the pressing platform 3 moves upward, thereby separating the pressing platform 3 from the support platform 9. At this time, the conductive sheet can be directly removed. This avoids the conductive sheet causing jamming when the support platform 9 moves upward, which would otherwise cause the support platform 9 to squeeze the conductive sheet and form a jam. This avoids the problem of the conductive sheet being unable to be removed.

[0071] After the conductive sheet is removed, the second cylinder 32 retracts and separates from the protrusion 33, and the mold support table 9 moves up to the initial position.

[0072] Preferred, such as Figure 6 As shown, it also includes a right-angled base plate 34, a mold support table 9 passes through the right-angled base plate 34 and slides relative to it, an elastic reset mechanism is provided between the bottom of the mold support table 9 and the right-angled base plate 34, and the bottom of the side plate 14 is fixed to the top of the right-angled base plate 34.

[0073] The mold support table 9 is provided with pressure plates 35 on both the front and rear sides. The bottom of the pressure plate 35 passes through the right-angle base plate 34 and slides relative to it. A third leaf spring 36 is connected between the pressure plate 35 and the right-angle base plate 34. A limiting post 37 is provided on the side wall of the pressure plate 35. A positioning plate 38 is provided on the side wall of the mold support table 9. The top of the positioning plate 38 extends to the top of the mold support table 9.

[0074] Specifically, two pressure plates 35 and a positioning plate 38 position the blank in three directions, placing the blank on top of the mold support table 9. The pressure plates 35 compress the blank, thus fixing it on the mold support table 9 and preventing the blank from deviating during the process of the pressure mold structure 1 approaching the mold support structure 2. The third leaf spring 36 provides auxiliary elastic tension to the pressure plate 35. When the bottom of the pressure mold table 3 contacts the blank, the pressure mold table 3 pushes the mold support table 9 downward through the blank. At this time, the third leaf spring 36 pulls the pressure plate 35 downward. When the limiting post 37 contacts the right-angle base plate 34, the limiting post 37 and the pressure plate 35 stop moving, thus preventing the pressure plate 35 from contacting and colliding with the mold post 13.

[0075] When positioning the billet, the three side walls of the billet contact the side walls of the two pressure plates 35 and the side wall of the positioning plate 38, respectively.

[0076] Preferred, such as Figure 6 As shown, the top of the pressure plate 35 is Z-shaped, and the lateral width of the pressure plate 35 is greater than the width of the placement groove 12, so that the pressure plate 35 can contact the top of the mold support table 9. The bottom part of the pressure plate 35 that contacts the top of the mold support table 9 is set as a plane, and the remaining part is set as an inclined surface, and the inclined surface is tilted in the direction away from the positioning plate 38.

[0077] Specifically, since the width of the pressure plate 35 is greater than the width of the placement groove 12, the top of the mold support table 9 and the pressure plate 35 can make contact. At this time, the blank is squeezed through the contact position, thereby achieving the pre-fixation of the blank. By setting an inclined surface on the pressure plate 35, the blank can be pushed horizontally between the top of the pressure plate 35 and the top of the mold support table 9 during feeding. At this time, the blank can push the pressure plate 35 upward through the inclined surface of the pressure plate 35, thereby achieving the feeding and clamping work.

[0078] To prevent the pressure plate 35 from contacting the inclined plate 6, the projection of the inclined plate 6 on the horizontal plane is located between the two pressure plates 35. In order for the inclined plate 6 to contact the column 13, the depth of the placement groove 12 is greater than the longitudinal length of the pressure plate 35, that is, the top part of the placement groove 12 is exposed on the outside of the pressure plate 35.

[0079] Preferred, such as Figure 8 and Figure 10 As shown, notches 39 are provided on the front and rear side walls of the mold support table 9. The bottom of the notches 39 extends to the bottom of the mold support table 9 and is connected to the through hole 10. Two fixing plates 40 are fixed to the bottom of the right-angle base plate 34. The fixing plates 40 pass through the notches 39 and are fixedly connected to the outer wall of the top column 11.

[0080] The outer side wall of the fixing plate 40 is provided with multiple vertical ribs 41, and the inner side wall of the notch 39 is provided with multiple vertical guide grooves, and the vertical ribs 41 are slidably installed in the guide grooves.

[0081] Specifically, when the mold support table 9 moves up and down, the fixing plate 40 slides within the notch 39, thereby causing the fixing plate 40 to move relative to the mold support table 9. The fixing plate 40 fixes the top column 11. By setting the vertical rib 41 and the guide groove, the fixing plate 40, the top column 11 and the mold support table 9 can be easily guided.

[0082] Preferred, such as Figure 8 As shown, the elastic reset mechanism includes a plurality of threaded rods 42 rotatably mounted on the side wall of the right-angle base plate 34. A torsion spring 43 is connected between the threaded rods 42 and the right-angle base plate 34. A threaded sleeve 44 is screwed onto the threaded rods 42. A connecting plate 45 is connected between the threaded sleeve 44 and the bottom of the mold support table 9.

[0083] Specifically, when the mold support table 9 moves downward, the mold support table 9 can push the threaded sleeve 44 to move downward through the connecting plate 45. The threaded sleeve 44 pushes the threaded rod 42 to rotate. At this time, the threaded rod 42 pushes the torsion spring 43 to undergo elastic deformation, thereby providing an upward reset force for the mold support table 9 through the torsion spring 43.

[0084] The present invention provides a molding process for a battery conductive sheet, comprising the following steps:

[0085] a. Insert the conductive sheet blank along the top surface of the mold support table 9 between the top of the mold support table 9 and the pressure plate 35. With the help of the inclined surface on the pressure plate 35, the blank can be inserted smoothly. The two pressure plates 35 and one positioning plate 38 can be used to position and pre-fix the conductive sheet.

[0086] b. The pressing platform 3 is pushed down by the hydraulic cylinder 31. The bottom of the pressing platform 3 contacts the blank and pushes the supporting platform 9 down through the blank. The elastic reset mechanism is deformed. When the blank moves to the top position of the side plate 14, the bottom edge of the pressing platform 3 squeezes the blank, so that the blank bends and deforms on the side plate 14. At this time, the initial deformation of the blank is achieved.

[0087] c. As the mold support table 9 moves down, the limiting post 37 contacts the right-angle base plate 34. At this time, the pressure plate 35 stops moving and the pressure plate 35 separates from the mold support table 9.

[0088] d. The pressing table 3 continues to move down, and the top of the top of the top column 11 and the top of the mold column 13 gradually extend to the outside of the mold support table 9. The top column 11 squeezes the blank on it into the spherical mold groove 4, and the inclined plate 6 squeezes the blank on the top of the placement groove 12 onto the mold column 13. At this time, the blank achieves two-stage deformation.

[0089] e. The corner plate 26 is moved by the first cylinder 27. The corner plate 26 moves the horizontal column 7 laterally and the punch 5 downward. The bottom of the punch 5 punches the blank in the spherical mold groove 4. The horizontal column 7 moves the push plate 8 synchronously through the locking mechanism. The push plate 8 presses the blank on it into the through 15 and fits with the baffle 16. The unlocking mechanism unlocks the locking mechanism. At this time, the blank on the end of the horizontal column 7 is squeezed out through the gap between the inner wall of the through 15 and the side wall of the baffle 16, thereby realizing the three-stage deformation of the blank. At this time, the blank is formed.

[0090] f. The first cylinder 27 pushes the horizontal column 7 and the push plate 8 to reset, the push cylinder 31 pulls the pressure mold table 3 upward in the opposite direction, and controls the extension of the second cylinder 32. The extended end of the second cylinder 32 contacts the protrusion 33 and presses the mold support table 9 so that it cannot move. At this time, the mold support table 9 separates from the pressure mold table 3 and the blank is taken out.

[0091] g. The second cylinder 32 gradually contracts, and the mold support table 9 is gradually reset through the elastic reset mechanism.

[0092] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
