A constant pressure feeding device for continuous nickel sheet stamping

Abstract

This utility model discloses a constant pressure feeding device for continuous nickel sheet stamping, relating to the field of metal strip stamping feeding technology. The utility model includes a feeding box, an adjusting plate fixedly connected to one side of the feeding box, a feeding roller fixedly connected to one side of the adjusting plate, and a guiding mechanism on the top of the adjusting plate. This utility model achieves flexible guidance through the elastic deformation of rubber airbags. When the nickel sheet shifts position during feeding, its edge contacts and squeezes the oppositely positioned rubber airbag, forcing the rubber airbag to undergo radial elastic deformation. This deformation process absorbs impact energy and generates a gentle, uniform reverse pressure on the nickel sheet, guiding it to automatically return to the central feeding path. This movement process replaces traditional hard collisions with elastic contact, effectively reducing the squeezing and scratching of the nickel sheet edges, thereby effectively reducing the probability of edge curling, burrs, or micro-cracks.

Description

Technical Field

[0001] This utility model belongs to the field of metal strip stamping and feeding technology, and in particular relates to a constant pressure feeding device for continuous stamping of nickel sheets. Background Technology

[0002] In the manufacturing of new energy products such as lithium batteries, nickel sheets, as an important conductive connecting material, need to be continuously stamped to prepare structures such as tabs. The constant pressure feeding device for continuous nickel sheet stamping refers to the equipment that can accurately and continuously feed strip nickel sheet material into the mold with constant and stable pressure during the stamping process. Its function is to ensure the accuracy of the feeding length and the stability of the material tension, which is crucial for improving stamping efficiency and ensuring product dimensional consistency.

[0003] In the existing technology of constant pressure feeding device for continuous nickel sheet stamping, there are still some problems in use. For example, the traditional feeding device's guide, clamping and feeding rollers are usually made of hard materials such as metal, which make direct and hard contact with the edge of the nickel sheet. The nickel sheet is relatively thin and the edge structure is particularly fragile. This hard contact can easily cause damage such as curling, burrs or microcracks on the edge of the nickel sheet during the feeding process. These micro defects will become stress concentration points in subsequent stamping processes, greatly increasing the risk of material fracture, leading to production interruption and increased scrap rate.

[0004] To address these issues, we provide a constant-pressure feeding device for continuous nickel sheet stamping. Utility Model Content

[0005] The purpose of this utility model is to provide a constant pressure feeding device for continuous nickel sheet stamping. Through the cooperation of the guiding mechanism and the mounting mechanism, it solves the problem that the existing constant pressure feeding device for continuous nickel sheet stamping has direct and hard contact with the edge of the nickel sheet, which is very easy to cause damage such as curling, burrs or micro-cracks to the edge of the nickel sheet during the feeding process.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a constant pressure feeding device for continuous nickel sheet stamping, comprising a feeding box, an adjusting plate fixedly connected to one side of the feeding box, a feeding roller fixedly connected to one side of the adjusting plate, a guiding mechanism provided on the top of the adjusting plate, the guiding mechanism comprising a guide rod provided on the top of the adjusting plate, a rubber airbag sleeved on the surface of the guide rod, and a limiting component provided between the guide rod and the rubber airbag, and an installation mechanism provided on the surface of the guide rod, the installation mechanism comprising a positioning plate provided on the surface of the guide rod, a fixing ring fixedly connected to one side of the positioning plate, and an insert ring provided inside the fixing ring.

[0008] The present invention is further configured such that there are four guide rods and four rubber airbags, and the guide rods and rubber airbags are designed in pairs facing each other.

[0009] The present invention is further configured such that the limiting component includes a limiting groove formed inside the guide rod, and a limiting rod disposed inside the limiting groove, the limiting rod being fixedly connected inside the rubber airbag.

[0010] The present invention is further configured such that two mounting mechanisms are arranged as a group at the top and bottom of the rubber airbag, and the rubber airbag is circular in shape.

[0011] The present invention is further configured such that the fixing ring has an insertion groove inside that is adapted to the insertion ring, the insertion groove and the insertion ring are both conical in shape, the fixing ring is made of rubber, and the outer diameter of the insertion ring is slightly larger than the inner diameter of the insertion groove in its natural state.

[0012] The present invention is further configured such that a pushing ring is fixedly connected to one side of the fixed ring, and the surface of the pushing ring is provided with anti-slip texture.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model achieves flexible guidance through the elastic deformation of the rubber airbag. When the nickel sheet shifts position during feeding, its edge contacts and squeezes the oppositely positioned rubber airbag, forcing the rubber airbag to undergo radial elastic deformation. This deformation process absorbs impact energy and generates a gentle, uniform reverse pressure on the nickel sheet, guiding it to automatically return to the central feeding path. This movement process replaces the traditional hard collision with elastic contact, effectively reducing the squeezing and scratching of the nickel sheet edge, thereby effectively reducing the probability of edge curling, burrs, or micro-cracks, and effectively ensuring the integrity of the nickel sheet and the subsequent stamping quality.

[0015] 2. This utility model achieves quick assembly and disassembly through the interference fit between the conical insert ring and the rubber fixing ring. During installation, the conical surface of the insert ring is aligned with the conical surface of the fixing ring and inserted into the groove, and an axial thrust is applied. The insert ring relies on its conical surface to self-center and gradually expand the rubber fixing ring, causing it to elastically expand and deform, generating a radial clamping force, thereby firmly locking the entire installation mechanism onto the guide rod. This movement process forms a tool-free elastic interference connection, allowing for quick replacement of worn rubber airbags, greatly improving equipment maintenance efficiency, and ensuring the long-term stability of the working position of the guide mechanism.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figures 1-5 This utility model is a constant pressure feeding device for continuous nickel sheet stamping, including a feeding box 1, an adjusting plate 2 fixedly connected to one side of the feeding box 1, a feeding roller 3 fixedly connected to one side of the adjusting plate 2, a guiding mechanism 4 provided on the top of the adjusting plate 2, the guiding mechanism 4 including a guide rod 41 provided on the top of the adjusting plate 2, a rubber air bag 42 sleeved on the surface of the guide rod 41, and a limiting component 43 provided between the guide rod 41 and the rubber air bag 42, an installation mechanism 5 provided on the surface of the guide rod 41, the installation mechanism 5 including a positioning plate 51 provided on the surface of the guide rod 41, a fixing ring 52 fixedly connected to one side of the positioning plate 51, and an insert ring 53 provided inside the fixing ring 52.

[0027] Specifically: By setting the guide mechanism 4, the nickel sheet is flexibly limited and guided. The nickel sheet passes between two sets of opposing rubber airbags 42. When the position of the nickel sheet is offset, its edge will contact and squeeze the rubber airbag 42. The rubber airbag 42 undergoes radial elastic deformation, absorbs the impact and generates a soft and uniform reverse pressure on the nickel sheet, forcing it to return to the center position, thus realizing non-rigid contact guidance. The elastic deformation of the rubber airbag 42 replaces the rigid impact of the traditional hard roller, effectively reducing the squeezing, scratching and hard impact on the edge of the nickel sheet. This helps to reduce the probability of edge curling, burrs or micro-cracks, ensuring the integrity of the nickel sheet and the quality of subsequent stamping. The installation mechanism 5 enables the quick installation and removal and axial fixation of the rubber airbag 42. When the rubber airbag 42 needs to be installed, the conical face of the insert ring 53 is aligned with the conical face of the inner side of the fixing ring 52 and inserted into the groove 6, and an axial thrust is applied. Since the outer diameter of the insert ring 53 is slightly larger than the inner diameter of the groove in its natural state, the rubber fixing ring 52 will undergo elastic expansion deformation, generating a huge radial clamping force. This force presses the fixing ring 52 tightly against the surface of the guide rod 41, and the overall locking is achieved through friction. During disassembly, the parts can be easily separated by reversing the operation. This process achieves a tool-free, fast, and reliable elastic interference fit. The conical design provides self-centering and progressive locking force, while the elasticity of the rubber material ensures sufficient clamping force and sealing. This allows for the rapid replacement of worn rubber airbags 42, greatly improving equipment maintenance efficiency.

[0028] Example 2

[0029] Please see Figures 1-5 Based on Embodiment 1, there are four guide rods 41 and four rubber airbags 42. The guide rods 41 and the rubber airbags 42 are designed in pairs facing each other. The limiting component 43 includes a limiting groove 431 opened inside the guide rod 41 and a limiting rod 432 set inside the limiting groove 431. The limiting rod 432 is fixedly connected inside the rubber airbag 42. The mounting mechanism 5 is set in pairs at the top and bottom of the rubber airbag 42. The rubber airbag 42 is circular in shape. The fixing ring 52 has an insertion groove 6 that matches the insertion ring 53. The insertion groove 6 and the insertion ring 53 are both conical in shape. The fixing ring 52 is made of rubber. The outer diameter of the insertion ring 53 is slightly larger than the inner diameter of the insertion groove 6 in its natural state. A pushing ring 7 is fixedly connected to one side of the fixing ring 52. The surface of the pushing ring 7 is provided with anti-slip texture.

[0030] Specifically: Four guide rods 41 and rubber airbags 42 are set on both sides of the top of the adjustment plate 2 to limit the two sides of the nickel sheet. The rubber airbags 42 can reduce the hard compression and scratching of the edge of the nickel sheet. The setting of the limiting component 43 limits the rubber airbags 42 to prevent the rubber airbags 42 from rotating on the surface of the guide rods 41 when the guide rods 41 rotate. The setting of the top and bottom mounting mechanism 5 limits the top and bottom of the rubber airbags 42 to prevent the rubber airbags 42 from shaking up and down during use. The setting of rubber material and insert ring 53 with a diameter slightly larger than the outer diameter allows the fixing ring 52 to generate a clamping force by its own elastic deformation when the insert ring 53 is inserted into the groove 6, pressing the fixing ring 52 against the guide rod 41. The rubber airbag 42 is fixed by the extrusion force and friction. The setting of the pushing ring 7 is used to push the insert ring 53 to move.

[0031] The working principle of this utility model is as follows: First, the bottom mounting mechanism 5 is fitted onto the surface of the guide rod 41, and the rubber airbag 42 is fitted onto the guide rod 41, ensuring that the limiting rod 432 inside the rubber airbag 42 is embedded in the limiting groove 431 of the guide rod 41 to prevent its circumferential rotation. Then, the top mounting mechanism 5 is fitted onto the surface of the guide rod 41, and after the rubber airbag 42 is adjusted to a suitable height, the conical end of the insert ring 53 is aligned with the conical insertion groove 6 of the fixing ring 52. By pressing and pushing the ring 7, the insert ring 53 is pushed into the insertion groove 6. Since the outer diameter of the insert ring 53 is slightly larger than the natural inner diameter of the insertion groove 6, the rubber fixing ring 52 undergoes elastic expansion deformation, generating a huge radial clamping force, thereby tightly pressing itself onto the surface of the guide rod 41, and achieving axial locking of the rubber airbag 42 through friction.

[0032] After the equipment is started, the feeding roller 3 rotates, feeding the nickel sheet into the guide channel formed by two sets of oppositely arranged rubber airbags 42. During the feeding process, if the nickel sheet deviates, its edge will contact and squeeze one side of the rubber airbag 42. The rubber airbag 42 undergoes radial elastic deformation, absorbing the impact and generating a gentle and uniform reverse pressure, guiding the nickel sheet to automatically return to the center feeding path. The cooperation between the limiting rod 432 and the limiting groove 431 ensures that the rubber airbag 42 does not rotate and always maintains the correct guiding posture, thereby completing the flexible feeding and correction of the nickel sheet.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
