Description

Technical Field

[0001] The utility model relates to the technical field of lithium-ion battery equipment, in particular to a novel quick-adjustment necking size tooling. Background Art

[0002] In the process of rapid development of new energy, cylindrical lithium-ion batteries have become the main choice in many industries such as the automotive industry and power tools. In the process of producing cylindrical batteries, one of the processes is to neck the steel shell. Most current manufacturers use flared steel shells. In order to make the winding core enter the steel shell more smoothly, after the winding core enters the steel shell, the mouth of the steel shell needs to be necked so that its size is the same as that of the lower part of the steel shell, which requires high equipment precision. After necking, the battery cell is placed on the upper insulating sheet and flows to the next process of rolling grooves.

[0003] The steel shell necking equipment generally includes a guiding component at the upper part and a necking component at the lower part. The guiding component is used to guide and position the steel shell so that the necking component can operate accurately on the steel shell, avoiding abnormal processing of the steel shell due to the concentricity deviation between the steel shell and the necking component. When adjusting the necking size of the existing steel shell necking equipment, it is necessary to remove all the upper guiding components for adjustment, which is time-consuming and affects product output. The installation precision of the upper guiding components is very high. When reinstalling after removal, it is difficult to debug the concentricity and it is easy to adjust poorly, resulting in marks on the steel shell and batch abnormalities.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model. Embodiment

[0022] As Figures 1-3As shown in the figure, a new type of tooling for quickly adjusting the necking size includes a steel shell necking mechanism and a steel shell guiding mechanism. The steel shell guiding mechanism includes a guiding mounting member 11 and a guiding member 12. The guiding mounting member 11 is arranged on the steel shell necking mechanism. A guiding mounting position is provided on the guiding mounting member 11. The guiding member 12 is arranged at the guiding mounting position and is detachable. A guiding channel is provided on the guiding member 12. The guiding channel is located at the necking operation end of the steel shell necking mechanism. The guiding channel is concentric and communicated with the necking operation port of the steel shell necking mechanism.

[0023] The guiding mounting member 11 provides a guiding mounting position suitable for the installation and connection of the guiding member 12 at the necking operation end of the steel shell guiding mechanism. The guiding member 12 is detachably mounted on the guiding mounting member 11 and the guiding channel of the guiding member 12 is concentric and communicated with the necking operation port of the steel shell necking mechanism. When it is necessary to adjust the necking size, the guiding member 12 can be removed and replaced with a guiding member 12 with a guiding channel that meets the requirements. The position of the guiding mounting position on the guiding mounting member 11 is fixed. After the guiding member 12 is installed at the guiding mounting position, its position relative to the guiding mounting member 11 is determined, and the position of the guiding mounting member 11 relative to the steel shell necking mechanism is determined. Therefore, when replacing the guiding member 12, it is not necessary to perform additional adjustment to make the guiding channel concentric with the necking operation port, thus effectively improving the adjustment of the necking size of the steel shell necking tooling.

[0024] Figure 1 and Figure 2 In the above, the upper end face of the steel shell necking mechanism is its necking operation end, and the guiding member 12 is arranged at the guiding mounting position and is located above the steel shell necking mechanism.

[0025] As a specific implementation manner of this embodiment, a guiding mounting hole is provided on the guiding mounting member 11 corresponding to the necking operation port of the steel shell necking mechanism. At least one connecting hole is circumferentially arranged around the guiding mounting hole on the guiding mounting member 11. The guiding mounting hole and each connecting hole form a guiding mounting position. The guiding member 12 includes a connecting disk. The connecting disk is an annular structure with a central hole provided at the center. The connecting disk is provided with through holes. When the connecting disk is arranged at the guiding mounting position, the through holes correspond to the connecting holes. The connecting disk is fixedly mounted at the guiding mounting position through connecting components such as bolts passing through the through holes and the connecting holes, and after the connecting disk is mounted at the guiding mounting position, its central hole is in a concentric state with the necking operation port. The inner wall of the central hole forms a guiding channel.

[0026] When performing a necking operation on the steel shell 3, the flared end of the steel shell 3 is passed through the guiding channel and extended into the necking operation port of the steel shell necking mechanism. After the steel shell necking mechanism performs a necking operation on the steel shell 3, the steel shell necking mechanism clamps the steel shell 3 and the steel shell 3 is in a state concentric with the guiding channel.

[0027] As a further implementation, a guiding tube is provided on the connecting disc. The guiding tube is perpendicularly connected to one end face of the connecting disc and communicates with the central hole. The inner diameter of the guiding tube is the same as the aperture of the central hole. The inner wall of the guiding tube forms an extended channel, and the extended channel communicates with the guiding channel. The function of the extended channel is the same as that of the guiding channel, which serves to extend the guiding channel. A longer guiding channel can achieve a better guiding effect on the steel shell 3. The guiding tube can be provided on the end face of the connecting disc away from the steel shell necking mechanism, or on the end face of the connecting disc facing the steel shell necking mechanism. Of course, connecting tubes can also be provided on both end faces of the connecting disc.

[0028] At least two parallel waist holes are provided on the guiding mounting member 11. The steel shell necking mechanism is provided with fastening holes suitable for connecting with the guiding mounting member 11. A connecting member passing through the waist holes is connected to the fastening holes, thereby mounting the guiding mounting member 11 to the steel shell necking mechanism. The fastening holes are preferably threaded holes, and the connecting member is a bolt adapted to the threaded holes. The bolt passes through the waist holes and is connected to the threaded holes to mount the guiding mounting member 11. The waist holes provided on the guiding mounting member 11 enable the guiding mounting member 11 to move and adjust relative to the steel shell necking mechanism, ensuring that after the guiding member 12 is mounted to the guiding mounting position, the guiding channel is concentric with the necking operation port.

[0029] Please refer to Figures 1-3 , the guiding mounting member 11 is preferably plate-shaped, and the guiding mounting member 11 is a guiding mounting plate.

[0030] At least one side position of the guiding mounting member 11 at the guiding mounting position is provided with a sensor mounting position 13. The sensor mounting position 13 can be several holes suitable for sensor mounting and connection. Sensors such as proximity switches can be mounted at the sensor mounting position 13 to detect whether there is a steel shell 3 in the guiding channel, which is convenient for the tooling of the present application to be connected to an automated production line for use.

[0031] To avoid the blocking of the sensor by the connecting disc or the guiding tube, a mounting pad is provided at the sensor mounting position 13. The sensor can be mounted on the mounting pad, and after the sensor is mounted on the mounting pad, it is in a state suitable for detecting the guiding channel opening.

[0032] Please refer to Figures 1-3, the steel shell necking mechanism includes a necking seat 21, a die mounting member 22, and a necking die 23. A die cavity is provided on the necking operation end face of the die mounting member 22. At least 3 separation grooves are circumferentially and equally spaced on the necking operation end face of the die mounting member 22. Each separation groove does not completely penetrate the die mounting member 22 axially. Each separation groove radially communicates with the inside of the die cavity and the outside of the die mounting member 22. Under the action of each separation groove, at least 3 necking members are formed on the part of the die mounting member 22 close to the necking operation end. Each necking member forms a multi-petal structure that can contract and expand on the part of the die mounting member 22 close to the necking operation end. The outer end face of each necking member is provided with a necking inclined surface.

[0033] A receiving cavity is provided on the necking seat 21. The steel shell guiding mechanism is arranged at the mouth of the receiving cavity. The guiding mounting member 11 is connected to the necking seat 21. The die mounting member 22 is arranged in the receiving cavity. The necking inclined surfaces of each necking member are in abutting fit with the mouth of the receiving cavity. The die mounting member 22 moves axially and drives each necking member to contract or expand. The necking inclined surface is a conical surface. The necking inclined surfaces of each necking member form an inverted frustum shape along the circumference. When the die mounting member 22 moves axially into the receiving cavity, the mouth abuts against each necking inclined surface, causing each necking member to contract and gather towards the center simultaneously. When the die mounting member 22 moves axially out of the receiving cavity, the squeezing and restraining effect of the mouth on each necking member becomes worse, and each necking member expands and diffuses outwards simultaneously.

[0034] The necking die 23 includes die components. Die components are provided on each necking member. The die components are in the die cavity and the inner end faces of each die component enclose a steel shell necking area. The steel shell necking area is a cylindrical cavity area. The flared part of the steel shell 3 to be necked is necked in the steel shell necking area. When the die mounting member 22 moves axially to make each necking member contract towards the center simultaneously, each die component approaches each other and simultaneously abuts against the steel shell 3 in the steel shell necking area. Each die component contracts towards the center simultaneously to perform a necking operation on the steel shell 3. When the die mounting member 22 moves axially to make each necking member expand towards the outside simultaneously, each die component moves away from each other and simultaneously releases the steel shell 3 in the steel shell necking area.

[0035] As an implementation method, a necking driving member is provided on the die mounting member 22. The necking driving member can be a linear driving component such as an oil cylinder or a cylinder. The action part of the necking driving member is connected to the die mounting member 22 and drives the die mounting member 22 to move axially to realize the necking operation on the steel shell 3.

[0036] As another implementation method, please refer to Figure 2The accommodating cavity is a circular cavity with an inner wall provided with an internal thread. A rotating member is provided in the accommodating cavity. The outer end surface of the rotating member is provided with an external thread. The rotating member cooperates with the accommodating cavity thread. The rotating member can also move along the axial direction of the accommodating cavity while rotating in the accommodating cavity. The mold mounting member 22 is connected to the rotating member. The rotating member can be driven to rotate by rotating the mold mounting member 22, thereby realizing the axial movement of the mold mounting member 22. It should be noted that Figure 2 The necking seat 21 is perspectively processed in the figure so as to better show the installation structure of the mold mounting part 22 in the necking seat 21.

[0037] Furthermore, the rotating part is a cylindrical structure with an external thread on the outer end face, the rotating part is concentric with the mold mounting part 22 and the end of the rotating part is connected to the mold mounting part 22, the rotating part and the mold mounting part 22 are an integrated structure, under the stress of the parts of the rotating part and the mold mounting part 22 that are not penetrated by the dividing groove, the multi-petal structure formed by each shrinking part can expand after losing the extrusion constraint of the accommodating cavity, and a rotating dial 24 is provided on the shrinking operation end face of the mold mounting part 22, and the mold mounting part 22 can be conveniently rotated by rotating the dial 24 to realize the shrinking operation of the steel shell 3.

[0038] The rotating member 24 may be a protruding structure or a groove structure provided on the mold mounting member 22 . The rotating member 24 may be driven to rotate by manually moving the protruding structure or by using a hexagonal wrench or other components to move the groove structure.

[0039] The guide mounting member 11 is provided with a shrinking operation avoidance hole 14 on the side of the guide mounting position, through which the rotating dial 24 can be operated to drive the mold mounting member 22 to rotate. The shrinking operation avoidance hole 14 is preferably two and distributed on both sides of the guide mounting position, so as to facilitate the operation of each rotating dial 24 to drive the shrinking mounting member to rotate.

[0040] In addition, the steel shell shrinking mechanism can be a shrinking component of an existing similar form of steel shell shrinking equipment.
