Description

Technical Field

[0001] The present invention relates to the field of forming of battery core poles, and in particular to a pole forging mechanism and a forging method. Background Art

[0002] The battery cell pole is the terminal on the new energy battery cell that is connected to the external conductor.

[0003] In the past, battery cell poles were stamped from a piece of solid pole material. The formed battery cell poles needed to undergo multiple punching and shaping processes. This method has a disadvantage. The pole material is in plate form, and the shape of the battery cell pole is flat, which means that the number of punching processes will be very large. Moreover, the shape and position of each punching are different, and the punched scraps are also of various shapes. The pole material is relatively expensive, and this production method will increase its output cost. Summary of the Invention

[0004] To solve the above problems, the present invention provides a pole forging mechanism and a forging method, which provides a new way to produce battery poles and reduces output costs.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a pole forging mechanism, characterized in that it includes:

[0006] The lower die assembly has a working surface divided into a blanking area, an avoidance area, and a stamping area in sequence, and is also provided with a guide component for guiding the material strip through the stamping area, the avoidance area, and the blanking area;

[0007] The upper die assembly is arranged above the lower die assembly and is provided with die cores corresponding to the stamping area and the blanking area;

[0008] The vibrating feeder has a feeding track on the output end extending to the avoidance area;

[0009] The lifting mechanism is embedded in the avoidance area, and its output end is opposite to the pole material discharged from the feeding track.

[0010] Furthermore, the guide component is a guide column with a channel provided on the side, and the two ends of the material strip are respectively mounted in the channel, and the guide column is rotatably connected to the above-mentioned working surface.

[0011] Furthermore, the mold core includes a first mold core and a second mold core located in the stamping area. The first mold core has a shape of a first opening punched on the material strip, and both ends of each circumferential surface of the first mold core are concave inward toward the center. The second mold core has a shape of a second opening formed around the first opening, so that the edge of the first opening protrudes into the second opening when deformed after being engaged with the battery cell.

[0012] Furthermore, the mold core includes a plurality of third mold cores arranged in the stamping area.

[0013] Furthermore, the feeding track is embedded in the working surface.

[0014] Furthermore, the blanking area is provided with discharge ports corresponding to the first mold core and the second mold core.

[0015] Beneficial effects of the present invention:

[0016] The pole forging mechanism of the present invention provides a new forging method. This forging method directly uses cylindrical pole materials, fixes the pole materials to the material strips by punching, and then punches the positioned pole materials. This method of producing battery cell poles saves the punching process, so the loss of pole materials is very small.

[0017] In addition, the material strip used in the present invention is based on the conversion of the pole material from a plate form to a cylindrical form. The traditional pole material is an integrated plate and will not shift. At this stage, the material strip is used to fix the cylindrical pole material.

[0018] A forging method comprises the following steps:

[0019] S1, the feeding belt mechanism pushes the material belt so that the material belt enters the channel on the guide column;

[0020] S2, performing the first mold closing, the first mold core forms a first opening in the material strip;

[0021] S3, the feeding belt mechanism pushes the material belt forward, performs secondary mold closing, and the second mold core punches out two second openings around the first opening;

[0022] S4, executing step S3 again, punching out second openings in two other directions around the first opening;

[0023] S5, the feeding belt mechanism pushes the material belt forward until the first opening and the pole material are opposite to each other, and the lifting cylinder pushes the pole material out from the discharge port so that the pole material is stuck in the first opening.

[0024] S6, the pole material is driven by the material strip and corresponds to the plurality of third mold cores respectively, and the pole material is pressed and formed by the third mold cores. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The pole forging mechanism of the present invention mainly provides a new pole preparation method.

[0034] like Figure 1-8 As shown, the above-mentioned pole forging mechanism includes:

[0035] The lower die assembly 1 has a working surface divided into a blanking area 102, an avoidance area 101, and a stamping area 100 in sequence, and is also provided with a guide component for guiding the material strip through the stamping area 100, the avoidance area 101, and the blanking area 102;

[0036] The upper die assembly 2 is arranged above the lower die assembly 1 and is provided with die cores corresponding to the stamping area 100 and the blanking area 102;

[0037] The vibrating feeder 3 has a feeding track 31 on its output end extending to the avoidance area 101;

[0038] The lifting mechanism is embedded in the avoidance area 101, with its output end facing the pole material 7 discharged from the feeding track 31;

[0039] The driving mechanism 5 has an output end connected to the upper mold assembly 2 to control the upper mold assembly 2 and the lower mold assembly 1 to close the mold.

[0040] The pole forging mechanism of the present invention provides a new forging method, which directly uses cylindrical pole material 7, fixes the pole material 7 to the material strip 6 by punching, and then punches the positioned pole material 7. This method of producing battery cell poles saves the punching process, so the loss of pole material 7 is very small.

[0041] In addition, the material strip 6 used in the present invention is based on the conversion of the pole material 7 from a plate form to a cylindrical form. The traditional pole material 7 is an integrated plate and will not shift. At this stage, the material strip 6 is used to fix the cylindrical pole material 7.

[0042] Furthermore, the guiding component is a guiding column 8 with a channel 81 on the side, and the two ends of the material belt 6 are respectively mounted in the channel 81, and the guiding column 8 is rotatably connected to the above-mentioned working surface; its purpose is to improve the smoothness of the movement of the material belt 6 on the lower mold assembly 1 and guide the moving direction of the material belt 6. Secondly, the volume of the guiding column 8 is relatively small, and the impact on the original design of the upper mold assembly 2 is relatively small; in addition, the material belt 6 can be suspended on the working surface of the lower mold assembly 1, avoiding the feeding track 31 of the vibrating feeder 3, and avoiding interference between the two.

[0043] Furthermore, the mold core includes a first mold core 100a and a second mold core located in the stamping area 100, the first mold core 100a has a shape of a first opening 61 punched on the material strip 6, and both ends of each peripheral surface of the first mold core 100a are concave toward the center, and the second mold core has a shape of a second opening 62 formed around the first opening 61, so that the edge of the first opening 61 is deformed after being engaged with the pole material to bulge into the second opening 62; the use of the first mold core 100a and the second mold core is to highlight the formation of a clamping structure on the material strip 6 specifically for clamping the pole material 7, and this clamping mechanism is composed of a plurality of second The opening 62 is combined with the first opening 61; this design is used in conjunction with a lifting mechanism to lift the pole material 7 so that when the pole material 7 passes through the first opening 61, the pole material 7 and the first opening 61 are interference fit; that is, the first opening 61 and the second opening 62 punched out by the first mold core 100a and the second mold core share the same frame, and the diameter of the pole material 7 is larger than the aperture of the first opening 61. When the pole material 7 squeezes into the first opening 61, the frame of the first opening 61 will deform and bulge into the first opening 61. At this time, the internal space of the second opening 62 provides space for the frame to deform.

[0044] Furthermore, the mold core includes a plurality of third mold cores arranged in the stamping area 100 , and different third mold cores have stamping openings of different shapes for stamping different parts of the pole material 7 respectively.

[0045] It should be noted that a mold sleeve corresponding to the third mold core is provided on the working surface of the lower mold assembly 1.

[0046] Furthermore, a groove is provided on the working surface, and the feed track 31 is arranged in the groove so that the feed track 31 is embedded in the working surface as a whole; its purpose is to fix the feed track 31 and ensure that the discharge port of the feed track 31 is located above the jacking mechanism.

[0047] The lifting mechanism is a lifting cylinder, the piston rod of which passes through the discharge port and pushes the pole material 7 into the first opening 61.

[0048] Furthermore, the blanking area 102 is provided with discharge ports corresponding to the first mold core 100a and the second mold core.

[0049] The above-mentioned driving mechanism 5 and vibrating feeder 3 are prior art, and their specific structures are not described in detail.

[0050] The forging method of the present invention:

[0051] S1, the feeding belt mechanism pushes the material belt 6 so that the material belt 6 enters the channel 81 on the guide column 8;

[0052] S2, performing the first mold closing, the first mold core 100a forms the first opening 61 in the material strip 6;

[0053] S3, the feeding belt mechanism pushes the material belt 6 forward, performs secondary mold closing, and the second mold core punches out two second openings 62 around the first opening 61;

[0054] S4, executing step S3 again, punching out second openings 62 in two other directions around the first opening 61;

[0055] S5 , the feeding belt mechanism pushes the material belt 6 forward until the first opening 61 and the pole material 7 are opposite to each other, and the lifting cylinder pushes the pole material 7 out from the discharge port, so that the pole material 7 is stuck in the first opening 61 .

[0056] S6 , the pole material 7 , driven by the material strip 6 , corresponds to the plurality of third mold cores respectively, and the pole material 7 is pressed and formed by the third mold cores.
