Description

Technical Field

[0001] This utility model belongs to the field of shredding technology, and in particular relates to a device for ensuring the quality of shredding. Background Technology

[0002] In the electrode production process, the high-speed wire cutter is the core equipment that determines the quality of wire pretreatment. The accuracy of the cut wire length and the flatness of the cut directly affect the uniformity of the electrode coating, the stability of the electrode's shape dimensions, and the final welding performance. Currently, the mainstream high-speed wire cutters in the industry adopt a "straightener-cutter" direct connection structure, that is, after the wire is straightened by the straightener, it needs to be directly fed into the cutter along a pre-reserved suspended conveying path between the two.

[0003] Because this suspended section lacks effective support and guidance, under high-speed wire cutting conditions (wire cutting speed is generally 80-120m / min), the wire is prone to radial swaying or axial displacement due to its insufficient rigidity, especially when the wire specification is a small diameter wire of φ1.6-φ3.2mm. At the same time, the release of residual minor stress after the wire exits the straightener will also cause irregular fluctuations in the wire conveying trajectory. The above problems directly lead to two major quality defects: first, unstable wire cutting, which is manifested as the wire cutting length deviation exceeding the industry standard requirement of ±0.5mm, with a failure rate of 5%-8%; second, uneven cutting edges, with phenomena such as burrs (height 0.3-0.8mm) and oblique cuts (cutting angle deviation >3°), which not only require additional deburring processes, but also cause the coating to not be tightly wrapped during subsequent flux coating, increasing the risk of cracking after the welding electrode dries, seriously affecting the welding electrode production efficiency and finished product quality. Utility Model Content

[0004] In view of this, the present invention aims to provide a device for ensuring the quality of shredding, so as to solve at least one technical problem in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A device for ensuring shredding quality includes a straightening component, a shredding component, an L-shaped base, and a shredding structure; The straightening component, the wire-dragging component, and the wire-cutting structure are sequentially installed at the vertical end of the L-shaped base; The wire-drawing assembly includes a bottom support plate, an upper cover plate, and a wire guide tube; The bottom support plate is installed on the vertical end of the L-shaped base, and the top cover plate is installed on the bottom support plate. The top cover plate has a through cavity, and the guide wire tube passes through the through cavity of the top cover plate. The wire is conveyed by a conveyor belt and passes through the guide tubes of the straightening component and the wire dragging component in sequence before entering the wire cutting structure for wire cutting.

[0006] Furthermore, the bottom support plate is L-shaped, and the vertical end of the bottom support plate is provided with a first mounting hole; the bottom support plate is set on the vertical end of the L-shaped base by a first locking bolt.

[0007] Furthermore, the upper cover plate has two second mounting holes on both the upper and lower sides, and the upper cover plate is installed on the horizontal end of the bottom support plate by the second locking bolt; The guide wire tube is positioned between the two second mounting holes.

[0008] Furthermore, the inner diameter of the guide tube corresponds to the outer diameter of the wire.

[0009] Furthermore, the straightening assembly includes a straightening plate and straightening components; Several straightening components are evenly arranged on the straightening plate, allowing the wire to pass between them, and the positions of the straightening components correspond to the positions of the wire guide tubes.

[0010] Furthermore, the straightening component includes two straightening rollers and two straightening shafts, with the two straightening shafts fixedly mounted on the straightening plate; The straightening roller is mounted on the straightening shaft.

[0011] Furthermore, the shredding structure includes an upper support plate, a lower support plate, a cutting hydraulic cylinder, and a cutting base; The upper support plate and the lower support plate are vertically set at the vertical end of the L-shaped base, with the upper support plate positioned above the lower support plate; The cutting base is installed above the lower support plate; one side of the cutting base is provided with a through groove that allows the output end of the cutting hydraulic pressure to move, and the bottom of the cutting base is provided with a first arc-shaped hole corresponding to the wire dragging assembly; The inner diameter of the through hole corresponds to the outer diameter of the wire; The mounting end of the cutting hydraulic cylinder is located below the upper support plate, and the output end of the cutting hydraulic cylinder is provided with a cutting blade. The cutting blade is provided with a second arc-shaped hole, and the cutting blade is slidably mounted on the cutting base. The cutting base is equipped with a sliding groove that allows the cutting disc to slide.

[0012] Furthermore, the cutting base is equipped with a guide rod, the other end of which is located below the upper support plate; The guide rod and the output end of the cutting hydraulic cylinder are equipped with a movable block. The output end of the cutting hydraulic cylinder drives the movable block to slide along the guide rod.

[0013] Compared with existing technologies, the device for ensuring shredding quality described in this utility model has the following advantages: 1. The straightening component of this application ensures that the wire is fully straightened before cutting, avoiding problems such as skewed cuts and inconsistent lengths caused by wire bending. The wire guide tube of the wire-drawing component performs a final precise positioning of the wire, effectively suppressing vibration and swaying of the wire during high-speed transport and ensuring the accuracy of the wire's position at the moment of cutting. Ultimately, this results in each cut section of wire having a highly straight shape.

[0014] 2. In this application, because the wire is strictly confined within the through-holes of the wire guide tube and the cutting base, no radial movement or twisting occurs during cutting. The arc-shaped hole design of the cutting blade and the cutting base creates an effect similar to "die shearing," resulting in a flat, smooth cut without burrs or flattening.

[0015] 3. This application achieves stable wire feeding and precise cutting, reducing the scrap rate during the production process. Attached Figure Description

Two straightening rollers are respectively fitted onto the straightening shafts and can rotate freely, used for preliminary straightening of the wire 5.

[0029] The bottom support plate 201 of the wire guide assembly 2 is L-shaped and is fixed to the L-shaped base 3 by the first locking bolt 205. The upper cover plate 202 is installed on the bottom support plate 201 by the second locking bolt 207. The wire guide tube 203 passes through the cavity of the upper cover plate 202, and its inner diameter matches the outer diameter of the wire 5 to ensure that the wire 5 passes smoothly and without swaying.

[0030] The upper support plate 401 and the lower support plate 402 of the shredding structure 4 are vertically fixed to the L-shaped base 3.

[0031] The cutting base 404 is installed on the lower support plate 402 and has a through groove 407 and a first arc-shaped hole 405 for the wire 5 to pass through.

[0032] A sliding groove 408 is used to guide the cutting blade 406 to slide. A cutting hydraulic cylinder 403 is installed below the upper support plate 401, and its output end is connected to the cutting blade 406. The cutting blade 406 has a second arc-shaped hole 410, which cooperates with the first arc-shaped hole 405 to complete the cutting of the wire 5. A guide rod 409 and a movable block ensure a stable and non-deviation-prone cutting process.

[0033] Securely install the L-shaped base 3 onto the equipment platform, ensuring that its vertical end is flat and firm.

[0034] The straightening plate 1 is fixed to the upper vertical end of the L-shaped base 3. Multiple straightening components 6 are mounted on the straightening plate 1 via their straightening shafts. Ensure that the two straightening rollers in each straightening component 6 can rotate freely. The bottom support plate 201 of the L-shape is fastened to the vertical end of the L-shaped base 3, located below the straightening assembly, through the first locking bolt 205 and the first mounting hole 204. The guide tube 203 is fixedly installed in the through cavity of the upper cover plate 202.

[0035] Place the upper cover plate 202 over the horizontal end of the bottom support plate 201 and secure it using the second locking bolt 207 through the second mounting hole 206. At this point, the wire guide tube 203 is tightly pressed between the bottom support plate 201 and the upper cover plate 202. At the lowest vertical end of the L-shaped base 3, vertically install the upper support plate 401 and the lower support plate 402. Install the cutting base 404 on the lower support plate 402, ensuring that the through slot 407 and the first arc-shaped hole 405 on it are concentrically aligned with the outlet of the wire guide tube 203 in the wire-drawing assembly 2. Fix the cutting hydraulic cylinder 403 below the upper support plate 401. Install the cutting disc 406 on the output end of the cutting hydraulic cylinder 403, and simultaneously embed the slider at the lower part of the cutting disc 406 into the sliding groove 408 of the cutting base 404. Install the guide rod 409, one end of which is fixed to the cutting base 404, and the other end passes through the movable block and connects to the upper support plate 401 to ensure the stability of the cutting process.

Ensure that the wire 5 remains smooth and unobstructed throughout the entire path.

[0037] Based on the diameter and curvature of the wire 5, the relative position or tightness of the straightening component 6 in the straightening assembly is finely adjusted so that the wire 5 can achieve an ideal straight state after passing through.

[0038] Operate the cutting hydraulic cylinder 403 and observe whether the second arc-shaped hole 410 of the cutting blade 406 can perfectly overlap with the first arc-shaped hole 405 of the cutting base 404 during the sliding process, forming a complete circular cutting space. Adjust the stroke of the hydraulic cylinder to ensure thorough cutting without excessive compression.

[0039] The conveyor belt is started, and wire 5 is continuously fed into the device. Wire 5 first passes through the straightening assembly, where it is straightened by multiple straightening rollers to eliminate the original bending stress. The straightened wire 5 enters the guide tube 203 of the wire-drawing assembly 2. The guide tube 203 plays a crucial guiding and restraining role, preventing the wire 5 from vibrating or deviating before entering the cutting zone. The straight and stable wire 5 finally enters the wire-cutting structure 4. At this point, the conveyor belt stops moving, and the cutting hydraulic cylinder 403 drives the cutting blade 406 to move rapidly along the sliding groove 408, cooperating with the cutting base 404 to cut the wire 5 like scissors. The conveyor belt continues to move, and the stopping and running of the conveyor belt are adjusted according to the length of the wire 5 being cut.

[0040] The conveyor belt and the cutting hydraulic cylinder 403 are both electrically connected to the controller, which uses existing PLC technology.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
