Description

Technical Field

[0001] This invention relates to the field of battery steel shell processing equipment technology, specifically a cylindrical battery steel shell end flange forming mechanism. Background Technology

[0002] With the rapid development of the new energy storage industry, cylindrical lithium batteries are widely used in power batteries, energy storage power stations and other fields due to their advantages such as high production efficiency, good consistency and low cost. In the production process of cylindrical batteries, the flanging and forming of the steel shell end is a key process before sealing. The quality of the flanging and forming directly affects the sealing performance of the subsequent sealing process, the overall structural strength of the battery and its safety in use.

[0003] Currently, most traditional cylindrical battery steel shell flanging forming equipment uses single-stage stamping flanging. This flanging process has some technical problems in actual use: First, after each stamping flanging is completed, the flanged steel shell needs to be manually removed, repositioned, and positioned before the next flanging forming work can continue. This requires a long downtime, reducing flanging efficiency. Second, the mechanisms used to fix the steel shell and the stamping mechanisms used for flanging on traditional equipment have poor versatility. When different models of steel shells need to be flanged, it takes a long time to completely disassemble and replace the positioning and stamping fixtures, which is cumbersome.

[0004] Therefore, it is necessary to provide a new cylindrical battery steel shell port flange forming mechanism to solve the above-mentioned technical problems. Summary of the Invention

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example:

[0021] Please refer to the following: Figures 1-15 The cylindrical battery steel shell end flange forming mechanism includes: a support base 1 and a U-shaped bracket 9 fixed on the top of the support base 1. A horizontal shifting mechanism is provided above the support base 1. The horizontal shifting mechanism includes a first U-shaped bracket 2 fixed on the top of the support base 1. A first vertical shifting shaft 201 is rotatably mounted on the first U-shaped bracket 2. A mounting platform 202 is fixed to the top of the first vertical shifting shaft 201. The top of the mounting platform 202 is fixedly connected to two U-shaped frames 3. A curved shifting groove 203 is formed on the first vertical shifting shaft 201. A first rodless cylinder 204 is fixed to the top of the support base 1. A linkage rod 205 is fixed to the slider of the first rodless cylinder 204. The linkage rod 205 passes through the curved transposition groove 203 and fits against the inner wall of the curved transposition groove 203. In the initial state, the linkage rod 205 fits against the bottom inner wall of the curved transposition groove 203. Through the sliding cooperation between the linkage rod 205 and the curved transposition groove 203, the mounting platform 202 can be rotated 180° quickly, thereby quickly realizing the alternation of the positions of the two hollow sliding platforms 5 proposed below.

[0022] In this embodiment, two orifice frames 3 are provided on the horizontal transposition mechanism. A transverse transposition shaft 301 is rotatably mounted on each of the two orifice frames 3. A bearing beam 303 is fixed to the opposite end of each of the two transverse transposition shafts 301. A support frame 4 is fixed to each of the two bearing beams 303.

Thus, two sets of mechanisms for placing steel shells are formed, and the multiple steel shell placement cylinders 6 on the two hollow sliding platforms 5 correspond one-to-one. Furthermore, by setting multiple steel shell placement cylinders 6 with different diameters, rapid switching according to the size of the steel shell can be achieved, improving operational efficiency. In addition, on the two orifice frames 3... Each of the two transverse shifting shafts 301 is fixedly equipped with a first gear, and a first spur gear is fixedly fitted on the output shaft of each of the two first gears. The two first spur gears mesh with the two second spur gears respectively. A connecting plate 302 is fixed to the two ends of the two transverse shifting shafts 301 that are far apart from each other. Two bearing beams 303 are fixedly connected to the two connecting plates 302 respectively. Two limiting rods are fixed to the outer walls of the two mouth-shaped frames 3 that are far apart from each other. The two corresponding limiting rods form a 120° angle. Limiting blocks are fixed to the two transverse shifting shafts 301. The two limiting blocks are located between the two corresponding limiting rods. In the initial state, the two limiting blocks are in contact with the corresponding limiting rods. By using the blocking of the two limiting rods, the rotation of the transverse shifting shafts 301 is limited, so that the hollow sliding stage 5 can rotate accurately to the specified state.

The steel shell inner wall support rod 1302 passes through the sliding hole and fits against the inner wall of the sliding hole. The lower edge of the sliding hole is rounded. This rounded design is the core structure of the flange and can cooperate with the flanged pressing ring 7. When the top of the steel shell contacts the rounded edge, it automatically deforms to realize the flanged process. A bearing is fixed on the top of the cylindrical outer shell 13. The folding frame 1304 carries an electric push rod 1305, and a connecting piece 1306 is fixed on the output shaft of the electric push rod 1305.

The connecting rods 1307 are slidably connected to the top of the cylindrical shell 13. During the processing, one of the stamping and flanging mechanisms is located directly above the corresponding steel shell placement cylinder 6 to smoothly realize the stamping and flanging process.

[0025] In this embodiment, in order to quickly adjust the corresponding steel shell placement cylinder 6, multiple point adjustment ports 401 are provided on the top of both support frames 4.

Locking slots are provided on one side of each of the multiple second-shaped brackets 8, and locking bolts 805 are threaded onto one side of each of the multiple lifting arms 802. One end of each locking bolt 805 passes through a locking slot and is fixed with a lock head. Each lock head abuts against one side of each of the multiple second-shaped brackets 8, and the diameter of the lock head is larger than the internal size of the locking slot.

Furthermore, standard graduation lines are engraved on each of the multiple lifting rods 803, and guide heads are fixed to the bottom of each of the multiple steel shell placement cylinders 6. These guide heads are matched with the standard graduation lines on the multiple lifting rods 803, thereby improving the accuracy of adjustment.

[0027] In this embodiment, when it is necessary to perform flanging processing on a non-standard sized steel shell, in order to quickly replace the steel shell placement cylinder 6, multiple mounting slots 501 are provided on the top of each of the two hollow sliding platforms 5. Insertion arms 502 are inserted into each of the multiple mounting slots 501, and the insertion arms 502 are fitted against the inner wall of the mounting slots 501. The tops of the multiple insertion arms 502 are respectively fixedly connected to multiple second U-shaped brackets 8. A transverse groove 503 is provided on one side of each of the multiple insertion arms 502. Multiple sliding openings 504 are provided on the top of each of the two hollow sliding platforms 5.

One end of the second return spring 508 is fixedly connected to the sliding plate 506, and the other end is fixedly connected to the inner wall of one side of the sliding opening 504. A first bevel is opened at the bottom of each of the plug arms 502. A second bevel is opened on the side of each transverse insert 507 that is inserted into the corresponding transverse groove 503. The first bevel is adapted to the second bevel.

[0028] In this embodiment, the multiple steel shell placement cylinders 6 and the five stamping and flanging mechanisms are all commonly used processing models, depending on the needs of daily production and processing.

[0029] When it is necessary to perform flanging on the steel shell, first select the corresponding stamping flanging mechanism according to the specifications of the steel shell. The specific operation is as follows: start the second reduction motor, and use the meshing of the two bevel teeth to drive the second vertical shifting shaft 10 to rotate. Every time the second vertical shifting shaft 10 rotates 72°, the switching of one stamping flanging mechanism is completed until the designated stamping flanging mechanism is switched to the top of the steel shell placement cylinder 6. It should be noted that after the second reduction motor rotates forward one revolution, it can be started to reverse, so that forward and reverse rotation are alternated, thereby ensuring that the wires on the turntable 11 will not get tangled.

[0030] Then, select the corresponding steel shell placement cylinder 6 according to the specifications of the steel shell. The specific operation is as follows: First, pull the pull plate 404 close to the ∟-shaped bracket 9 to pull out the corresponding point positioning rod 403 from the corresponding point adjustment through hole 401. At this time, the first return spring 405 is in a compressed state. Then, slide the hollow sliding table 5. After moving the specified steel shell placement cylinder 6 to directly below the stamping and flanging mechanism, the point positioning rod 403 also corresponds up and down with the corresponding point adjustment through hole 401. Immediately release the pull plate 404, and the compressed first return spring 405 rebounds, automatically bringing the point positioning rod 403 into the corresponding point adjustment through hole 401, thus completing the switching of one steel shell placement cylinder 6. Then, switch the steel shell placement cylinder 6 on the other hollow sliding table 5 in the same manner as above.至此,完成两个中空滑移台5上的钢壳放置筒6的位置切换。

[0031] Subsequently, place steel shells of corresponding sizes into the corresponding steel shell placement cylinders 6 away from the ∟-shaped bracket 9. The steel shells fit perfectly with the inner walls of the steel shell placement cylinders 6. Immediately afterwards, adjust the length of the top of the steel shell protruding from the top of the flanging and pressing ring 7. When adjusting, first reverse-rotate the corresponding locking bolt 805 to separate the locking head at its end from the second ∟-shaped bracket 8. Then, rotate the anti-slip rotating handle to drive the corresponding adjusting screw rod 801 to rotate. At this time, the lifting arm 802 raises or lowers the lifting rod 803, and the placed steel shells also rise or fall accordingly. Stop rotating the adjusting screw rod 801 until the top of the steel shell is flush with the top of the flanging and pressing ring 7. At this time, visually observe the position of the guiding head on the scale line and record it. Set this position as the starting scale. Then, continue to rotate the adjusting screw rod 801. At this time, the top of the steel shell gradually protrudes from the top of the flanging and pressing ring 7. Tighten the locking bolt 805 until the guiding head points to the corresponding scale line.至此,钢壳凸出于翻边压合环7顶端的长度便是翻边长度。

[0032] Next, the first rodless cylinder 204 is activated, and its slider, carrying the linkage rod 205, rises. Utilizing its interaction with the curved transposition groove 203, the first vertical transposition shaft 201 rotates, carrying the mounting platform 202, until the linkage rod 205 is in contact with the top inner wall of the curved transposition groove 203. At this point, the two hollow sliding platforms 5 have exchanged positions. The placed steel shell is now directly below the previously switched stamping and flanging mechanism. Then, the corresponding second rodless cylinder 1301 is activated, and its slider, carrying the steel shell's inner wall support rod 1302... The steel shell descends and is eventually inserted directly into the steel shell, perfectly fitting the inner wall of the steel shell. At this time, the steel shell is stably positioned by the inner and outer supports of the steel shell placement cylinder 6 and the inner wall support rod 1302. Then, the output shaft of the corresponding electric push rod 1305 is extended, and the corresponding connecting rod 1307 lowers the corresponding flange stamping ring 1303. When the rounded edge of the flange stamping ring 1303 contacts the top of the steel shell, the steel shell automatically flips. At this time, under the pressure of the flange pressing ring 7 and the flange stamping ring 1303, the steel shell is finally flanged.

[0033] While one side is stamping and flanging, the other side places the steel shell into the corresponding steel shell placement cylinder 6 in the same manner. After the current steel shell stamping and flanging is completed, the electric push rod 1305 and the second rodless cylinder 1301 are activated in sequence to bring the inner wall support rod 1302 and the flanging stamping ring 1303 of the steel shell back to their original positions. Then, the first rodless cylinder 204 is activated again to lower the linkage rod 205, thereby causing the two hollow sliding tables 5 to exchange positions again. At this point, the stamping and flanging work on the previously placed steel shell can continue. On the other side, the corresponding first reduction motor is activated in the forward direction, and its output shaft drives the corresponding horizontal... The transverse shifting shaft 301 rotates, causing the corresponding hollow sliding table 5 to rotate as well. When the limit block on the transverse shifting shaft 301 rotates to engage with another limit bar, the steel shell that has just been flipped tilts downwards and naturally falls into the guide channel steel 14, then into the belt conveyor unit 15 to be conveyed to the next process. After the material is discharged, the corresponding first reduction motor is started in reverse to rotate the hollow sliding table 5 back to its original state, and then the next steel shell is placed. After the previous steel shell is flipped, the same operation is repeated, and so on, so as to achieve the synchronous operation of stamping and flipping while discharging and feeding.

[0034] Furthermore, when processing the same batch of steel shells, only the steel shell placement seat 804 needs to be adjusted before processing to ensure continuous production of steel shells of the same specification. Simultaneously, when switching to other steel shell placement cylinders 6 and stamping and flanging mechanisms, the switch can be quickly completed by adjusting the insertion position of the point insertion rod 403 and starting the second reduction motor. In addition, for processing non-standard sized steel shells, tooling can be quickly disassembled and replaced. Specifically, by pushing the sliding plate 506, the corresponding transverse insert 507 is pulled out of the corresponding transverse groove 503, allowing the insertion arm 502 to be removed, and then the corresponding steel shell can be taken out. Place the tube 6 and insert its plug arm 502 into the mounting socket 501. During the insertion process, the first bevel at the bottom of the plug arm 502 will contact the second bevel on the transverse insert 507. The transverse insert 507 will self-retract and compress the second return spring 508. After the plug arm 502 is inserted into place, the second return spring 508 will rebound and automatically bring the transverse insert 507 into the transverse groove 503, thereby quickly completing the replacement of the steel shell tube 6. At the same time, the corresponding cylindrical shell 13 can be removed and replaced by unscrewing the bolt on the mounting ring 1308, thereby completing the replacement of the stamping and flanging mechanism.
