Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of punching chamfering, in particular to a chamfering device for electrode post processing. BACKGROUND

[0002] The battery post is a core component in the battery system that realizes the electrical connection between the internal cell and the external circuit, which not only affects the current transmission efficiency, but also directly relates to the safety, reliability and service life of the battery.

[0003] The core function of the post is to conduct electricity and seal. As the "gateway" for current to enter and exit the battery, it must maintain low resistance and high current carrying capacity throughout its life cycle, while strictly isolating the battery interior from the external environment to prevent electrolyte leakage and external contaminants from entering.

[0004] Therefore, the battery post is composed of a base part (responsible for connecting with the battery and cooperating with the seal) and a cylindrical part (responsible for wiring, external output or power input). During actual assembly, the side edge of the base part is relatively sharp, which can easily extrude burrs during assembly. The burrs are not only impurities, but also can pierce the seal, causing the battery seal to fail, so the surface needs to be chamfered.

[0005] In the prior art, chamfering is mostly done by cutting. It is relatively easy to chamfer a circular base, but it is difficult to cut a non-circular shape (such as a rectangular or irregular shape), and the size is not easy to control.

[0006] Therefore, the present application proposes a chamfering device for electrode post processing. SUMMARY

[0017] Meanwhile, the lower die is provided with one air hole at the middle of each of the two sides, and the lower die is provided with another air hole at the inner wall on the same side of the two air holes.

[0018] As a more preferred scheme of the application, the other side of the air hole is connected with a solenoid valve, the other end of the solenoid valve is connected with a multi-way pipe, and the other side of the multi-way pipe is connected with a high-pressure gas tank through a hose.

[0033] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0034] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] Example 1: A chamfering device for machining electrode posts, such as Figures 1-8 As shown, the system includes a workbench 1. A gantry frame 6 is bolted to the outer wall of the workbench 1. An upper hydraulic rod 4 is bolted to the top outer wall of the gantry frame 6. An upper plate 5 is bolted to the telescopic end of the upper hydraulic rod 4. An upper mold 7 is bolted to the bottom outer wall of the upper plate 5. A lower hydraulic rod 11 is bolted to the bottom outer wall of the workbench 1 located below the upper mold 7. A lower plate 10 is bolted to the telescopic end of the lower hydraulic rod 11. A lower mold 9 that mates with the upper mold 7 is bolted to the top outer wall of the lower plate 10. A chamfering blade 12 for extruding and chamfering one side of the electrode post is provided at the bottom of the upper mold 7. A chamfering blade 23 for chamfering the other side of the electrode post is provided on the inner wall of the lower mold 9.

[0036] When using this device, the electrode post to be processed can be inserted into the lower mold 9 first. Then, the upper hydraulic rod 4 and the lower hydraulic rod 11 extend synchronously, so that the upper mold 7 and the lower mold 9 gradually approach each other until the upper mold 7 and the lower mold 9 apply impact pressure to the electrode post from both sides. Then, the electrode post is stamped and chamfered using chamfering cutter 12 and chamfering cutter 23.

[0037] This device, by setting up an upper mold 7 and a lower mold 9, uses chamfering cutter 12 and chamfering cutter 13 on the upper mold 7 and the lower mold 9 respectively to chamfer the two ends of the electrode post. Compared with the traditional cutting process for chamfering, the die stamping forming can be applied to chamfering forming under different shapes.

[0038] likeFigure 1 As shown, the side outer wall of the workbench 1 is provided with a vibrating feeder 2 for vibrating feeding, and the discharge port of the vibrating feeder 2 is provided with a material guide frame 3 for guiding the electrode column, and the workbench 1 is provided with a group of material receiving and limiting assemblies 8 for preliminarily limiting the electrode column at the stamping positions on both sides of the upper die 7 and the lower die 9.

[0039] The material receiving and limiting assembly 8 comprises a support frame 16, a guide rod 17, a spring 18 and a limiting baffle 19, the support frame 16 is fixed on the top outer wall of the workbench 1 by bolts, the limiting baffle 19 is slidably connected to the side wall of the support frame 16 by the guide rod 17, the outer wall of the guide rod 17 is sleeved with the spring 18, one end of the spring 18 is buckled to the side wall of the limiting baffle 19, and the other end of the spring 18 is buckled to the side wall of the support frame 16, and the limiting baffle 19 is matched with the outer shape of the electrode column.

[0040] The material receiving and limiting assembly 8 further comprises a baffle 14 and a telescopic rod 15, the telescopic rod 15 is fixed on the outer wall of the support frame 16 by bolts, and the baffle 14 is fixed on the telescopic end of the telescopic rod 15 by bolts.

[0041] The vibrating feeder 2 can vibrate the electrode column, and the electrode column after feeding is arranged and falls along the material guide frame 3 until it falls to the two limiting baffles 19 combined and matched, the two limiting baffles 19 limit the electrode column, and at the same time the telescopic rod 15 extends to drive the baffle 14 to extend, which separates the adjacent two electrode columns, then the lower die 9 rises and the upper die 7 descends until the bottom of the electrode column is inserted into the hole of the lower die 9 to obtain a certain limiting, then the two limiting baffles 19 are quickly separated, the electrode column falls into the lower die 9, then the upper die 7 and the lower die 9 continue to approach and cooperate to stamp and chamfer.

[0042] The device, based on the vibrating feeding of the vibrating feeder 2, further utilizes the limiting of the limiting baffle 19 and the material separation of the baffle 14, so as to realize the full-automatic processing of the whole stamping and chamfering process by programming control of the movement timing of the upper die 7, the lower die 9, the baffle 14 and the limiting baffle 19.

[0043] In order to solve the driving problem; such as Figure 5 , 6As shown, the lower plate 10 is slidably connected to the workbench 1 by the guide rod two 20, and the bottom outer wall of the guide rod two 20 is fixed with a connecting plate 27 by bolts, one of the guide rod one 17 is engaged with the gear 24 through the tooth groove 26 at the bottom thereof, one side of the gear 24 is coaxially fixed with the winding drum 23, the winding drum 23 is rotatably connected to the side wall of the support frame 16 by the wheel shaft 25, the bottom outer wall of the workbench 1 is rotatably connected with the reversing wheel 22, the bottom side of the connecting plate 27 is fixed with the hoisting rope 21, the other end of the hoisting rope 21 is fixed to the outer wall of the winding drum 23 after being fitted to the outer wall of the reversing wheel 22.

[0044] When the lower plate 10 moves to the bottom, the hoisting rope 21 is arranged to be inclined downward from the reversing wheel 22 to the connecting plate 27 at this time, and the two limiting baffle plates 19 are fitted to each other at this time, then when the lower plate 10 is driven to rise by the lower hydraulic rod 11, the hoisting rope 21 will first relax due to the mutual abutting limiting of the two limiting baffle plates 19, until the connecting plate 27 continues to rise with the lower plate 10, and the bottom of the electrode column is inserted into the inside of the lower die 9 to preliminarily limit, then the hoisting rope 21 is taut, and then the connecting plate 27 continues to rise, which will pull the hoisting rope 21 and drive the winding drum 23 to rotate, thereby driving the gear 24 to rotate, and then driving the two limiting baffle plates 19 to separate and avoid the stamping space through the engagement of the gear 24 and the tooth groove 26 and the guide rod one 17 after the stamping is completed, the lower plate 10 is lowered, and the limiting baffle plates 19 are gradually reset to abut by the elastic force of the springs 18.

[0045] The device, by setting the hoisting rope 21, the gear 24, the tooth groove 26 and other components, the separating and combining movements of the limiting baffle plates 19 are integrated into the lifting of the lower plate 10, so that it can be realized by the driving of the lower hydraulic rod 11, which increases the synchronization of the whole device, and through the length setting of the hoisting rope 21, it can also realize that the limiting baffle plates 19 are driven to move only after the electrode column is partially inserted into the inside of the lower die 9 to limit, thereby ensuring the reliability of the electrode column stamping chamfering.

[0046] In this embodiment, the vibratory feeder 2 vibrates and feeds the electrode posts. After feeding, the electrode posts are arranged and fall along the guide frame 3 until they fall to the two combined limiting baffles 19. The two limiting baffles 19 limit the electrode posts, and at the same time, the telescopic rod 15 extends to drive the baffle 14 to extend, which separates two adjacent electrode posts. Then, the upper hydraulic rod 4 and the lower hydraulic rod 11 drive the lower mold 9 to rise and the upper mold 7 to fall, respectively. At the same time, when the lower plate 10 moves to the bottom, the winch 21 is arranged inclined downward from the reversing wheel 22 toward the connecting plate 27, and the two limiting baffles 19 are in close contact with each other. Then, the lower plate 10 is driven to rise by the lower hydraulic rod 11. At that time, due to the two limiting baffles 19 and their mutual contact limiting, the twisted rope 21 will first loosen until the connecting plate 27 continues to rise with the lower plate 10 and the bottom of the electrode post is inserted into the interior of the lower mold 9 for initial limiting. Then the twisted rope 21 will straighten. Subsequently, the connecting plate 27 will continue to rise, which will pull the twisted rope 21 and drive the drum 23 to rotate, thereby driving the gear 24 to rotate. Then, through the meshing of the gear 24 and the tooth groove 26, the guide rod 17 will pull the two limiting baffles 19 to separate and avoid the stamping space. Then the upper mold 7 and the lower mold 9 will gradually approach each other until the upper mold 7 and the lower mold 9 apply impact pressure to the electrode post from both sides. Then, the chamfering knife 12 and the chamfering knife 23 will be used to stamp and chamfer the electrode post.

[0047] Example 2: A chamfering device for machining electrode posts, such as... Figure 7 As shown, in order to solve the problem of automatic feeding, this embodiment makes the following improvements based on embodiment 1: an air hole 28 is opened on each side of the middle part of the lower mold 9, and another air hole 28 is opened on the inner wall of the lower mold 9 on the same side as the two air holes 28. A solenoid valve 29 is connected to the other side of the air hole 28, and a multi-port pipe 30 is connected to the other end of the solenoid valve 29. A high-pressure air tank 32 is connected to the other side of the multi-port pipe 30 through a hose 31.

[0048] In this embodiment, after the stamping is completed, the electrode post will be inside the lower die 9 due to gravity. At this time, the solenoid valve 29 connected to the two central air holes 28 is first opened, and the high-pressure gas in the high-pressure gas tank 32 is ejected from the air hole 28 to push the electrode post out. Then it is immediately closed. Next, the solenoid valve 29 connected to the air hole 28 on the other side is opened, and the high-pressure gas in the high-pressure gas tank 32 is transmitted to this air hole 28, thereby applying a force to one side of the electrode post and blowing the electrode post away from the lower die 9 to achieve material unloading.

[0049] This device, by setting up components such as air holes 28 and high-pressure air tanks 32, can, on the one hand, use the blowing of gas to make the electrode post separate longitudinally from the lower mold 9, and on the other hand, can also make the electrode post separate laterally relative to the lower mold 9 by opening the sequence of air holes 28, thereby realizing the automatic feeding function.

[0050] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
