Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically to an automatic core-setting extrusion device for new energy vehicle cables that requires no adjustment. Background Technology

[0002] With the rapid development of the market economy, the application of wires and cables is increasing. The production of new energy vehicles is also inseparable from the application of cables. In the wire and cable processing process, the use of production molds for flat cables is essential. Flat cables are produced in a standardized manner. The flat structure is particularly suitable for occasions with frequent bending, without twisting, and folds neatly.

[0003] In the production of flat cables, mold adjustment takes a long time and requires mold changes to adapt to different cable specifications. Utility model publication CN210590484U discloses a new energy vehicle cable extrusion mold that does not require adjustment. It connects a set of extrusion plates with U-shaped grooves inside the upper and lower covers, and fixes them with nuts and screws, thus facilitating the replacement of extrusion plates according to different orders. Although this prior art can be applied to the extrusion of cables of different specifications, in actual use, it not only cannot achieve automatic cable core setting, but also requires the replacement of extrusion plates according to cable specifications, resulting in low efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic core-setting extrusion device for new energy vehicle cables that does not require adjustment, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic core-setting extrusion device for new energy vehicle cables, used for processing flat cables, includes a top plate, a lifting plate, and a lower die mechanism. The top plate is connected to the lower die mechanism via at least one guide rod. The lifting plate is slidably connected to the guide rod. A hydraulic rod is fixedly installed at the bottom of the top plate, and the telescopic end of the hydraulic rod is connected to the lifting plate. The lower die mechanism includes a base and two movable plates symmetrically arranged on the left and right sides of the base. The base has a U-shaped structure. A movable seat is slidably installed at the bottom of the movable plate, and the movable seat is slidably connected to the base. A drive mechanism for moving the movable seat is also provided inside the base.

[0007] As a further embodiment of this utility model: a limiting mechanism is also provided between the side of the movable plate and the base. The limiting mechanism includes a crossbar and a sliding sleeve. One end of the crossbar is fixedly connected to the base, and the other end of the crossbar is slidably connected to the sliding sleeve.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 In this embodiment of the utility model, an automatic core-setting extrusion device for new energy vehicle cables without adjustment is used for processing flat cables. It includes a top plate 10, a lifting plate 20, and a lower mold mechanism 30. The top plate 10, the lifting plate 20, and the lower mold mechanism 30 are arranged sequentially from top to bottom. The top plate 10 is connected to the lower mold mechanism 30 through at least one guide rod 12. The lifting plate 20 is slidably connected to the guide rod 12. A hydraulic rod 11 is fixedly installed at the bottom of the top plate 10. The telescopic end of the hydraulic rod 11 is connected to the lifting plate 20. When the telescopic end of the hydraulic rod 11 extends, the lifting plate 20 moves toward the lower mold mechanism 30. After the lifting plate 20 contacts the lower mold mechanism 30, the mold is closed. The cable material can be formed into a flat cable after passing through the extrusion device after the mold is closed.

[0022] In this embodiment, the lower mold mechanism 30 includes a base 31 and two movable plates 32 symmetrically arranged on the left and right sides of the base 31. The base 31 has a U-shaped structure. A movable seat 321 is slidably installed on the bottom of the movable plate 32 and is slidably connected to the base 31. The base 31 is also provided with a drive mechanism for driving the movable seat 321 to move. Before the cable material is extruded, the lifting plate 20 and the lower mold mechanism 30 close the mold. Then, the drive mechanism drives the movable seat 321 to move, so that the movable seat 321 drives the movable plate 32 to move. An extrusion space for the cable material is formed between the two movable plates 32. After the cable material passes through the extrusion space, it can be formed into a flat cable.

[0023] Furthermore, in this embodiment, a limiting mechanism 37 is provided between the side of the movable plate 32 and the base 31. The limiting mechanism 37 includes a crossbar 371 and a sliding sleeve 374. One end of the crossbar 371 is fixedly connected to the base 31, and the other end of the crossbar 371 is slidably connected to the sliding sleeve 374. The crossbar 371 is provided with a plurality of protrusions 373, and the sliding sleeve 374 is provided with a plurality of limiting holes 375 corresponding to the protrusions 373. It should be noted that when the driving mechanism drives the movable seat 321 to move, the movable seat 321 drives the movable plate 32. The moving plate 32 is moved to adjust its position laterally. In actual use, since the cable material has various widths, different sizes of cable material are placed between the two moving plates 32. The cable material squeezes the moving plate 32, causing the moving plate 32 to slide on the moving seat 321, thereby fine-tuning the lateral position of the moving plate 32. After the fine-tuning is completed, the lifting plate 20 and the lower mold mechanism 30 close the mold, and the protrusion 373 on the crossbar 371 enters the limiting hole 375 to prevent the sliding sleeve 374 from moving, thereby limiting the moving plate 32 and preventing the moving plate 32 from moving during the extrusion process.

[0024] Furthermore, in this embodiment, an electromagnetic button 36 is installed on the side of the base 31, and a groove for the protrusion 373 to slide is opened inside the crossbar 371. An electromagnet is provided at the bottom of the groove. The protrusion 373 is made of iron material. When the electromagnet is energized, it attracts the protrusion 373, causing the protrusion 373 to retract into the groove. A power source (not shown in the figure) is provided inside the base 31. The power source is electrically connected to the electromagnetic button 36 and the electromagnet through a wire 377. In the initial state, the electromagnetic button 36 is in the closed state, and the electromagnet is energized. When the lifting plate 20 and the lower mold mechanism 30 close the mold, the lifting plate 20 presses the electromagnetic button 36, and the electromagnetic button 36 changes from the closed state to the open state. The electromagnet is de-energized, and the fine adjustment of the moving plate 32 ends. The protrusion 373 passes into the limiting hole 375, thereby limiting the sliding sleeve 374 and the moving plate 32.

[0025] In this embodiment, the driving mechanism includes an adjusting screw 381 rotatably mounted inside the base 31 and two threaded sleeves 383 symmetrically arranged on both sides of the adjusting screw 381. The threaded sleeves 383 are threadedly connected to the adjusting screw 381 and fixedly connected to the movable seat 321. The adjusting screw 381 has two types of external threads with opposite directions on both sides. When the adjusting screw 381 rotates, the threaded sleeves 383 drive the movable seat 321 and the movable plate 32 to move, thereby adjusting the position of the cable material so that the cable material is at the center of the base 31, thereby realizing automatic core setting of the cable material.

[0026] Furthermore, in this embodiment of the application, the bottom of the base 31 is also equipped with a support leg 33 and a drive motor 38, and the drive motor 38 is connected to the adjusting screw 381 through a bevel gear set 382.

[0027] Furthermore, in this embodiment of the application, the base 31 is provided with a through groove 34 and at least one guide groove 35, the screw sleeve 383 passes through the through groove 34 and is connected to the movable seat 321, and the movable seat 321 is slidably connected to the guide groove 35.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
