Description

Technical Field

[0001] This utility model belongs to the field of flat wire pressing technology, and more specifically, relates to a pressing device for flat wires. Background Technology

[0002] Flat wire, also known as flat yarn, flattened wire, flat-angle wire, or ultra-narrow strip, refers to irregularly shaped metal wire with a cross-section that is approximately rounded rectangular. Flat wire is generally produced using a rolling mill through hot rolling or cold rolling processes.

[0003] Before processing flat wire, it needs to be crimped. The flat wire crimping device stretches and compresses the flat wire to achieve the appropriate thickness and width. However, existing flat wire crimping devices have poor clamping effect and lack guiding and limiting functions during the wire guiding process, which may lead to problems such as wire misalignment. Utility Model Content

[0004] This invention provides a crimping device for flat wires, which can stabilize the crimping of flat wires and improve the crimping effect.

[0005] This utility model discloses a pressing device for flat wire, comprising: a winding mechanism for carrying and releasing the flat wire; a lead wire mechanism disposed at the rear end of the winding mechanism, including a tensioning part, a lead wire limiting part, and a pressing part; wherein, the tensioning part includes an adjustable movable arm and a pressing wheel assembly for adjusting the tension of the flat wire and forming a limiting path; the lead wire limiting part includes multiple staggered lead wire wheels with lead wire grooves on their outer circumferences to limit the width of the flat wire; the pressing part includes multiple opposing second pressing wheels with pressing guide grooves on their outer circumferences for pressing the thickness of the flat wire; and a pressing mechanism disposed at the rear end of the lead wire mechanism, including a main rotating wheel, a pressing wheel, and a support member; wherein, the main rotating wheel has a pressing groove on its outer circumference, and the pressing wheel has a pressing protrusion on its outer circumference that matches the pressing groove, and the distance between the two is less than the thickness of the flat wire; the support member connects to the pressing wheel and maintains its rotational engagement with the main rotating wheel to achieve continuous pressing of the flat wire.

[0006] As a further improvement of this utility model, the tensioning part also includes a mounting frame and a limiting wheel. The limiting wheel is arranged in pairs in the hollow part of the mounting frame to guide the flat wire to move along a preset path.

[0007] As a further improvement of this utility model, the pressing wheel set includes a pair of wheel bodies arranged opposite each other, and a wheel set limiting groove is provided in the middle of the outer periphery of each wheel body to form a limiting channel for the flat wire.

[0008] As a further improvement of this utility model, the lead wire reels are S-shaped when viewed from above, and a limiting path for the flat wire to pass through is formed between adjacent lead wire reels.

[0009] As a further improvement of this utility model, the clamping mechanism also includes a drive motor and a driven wheel. The drive motor is connected to the main rotating wheel, and the driven wheel rotates synchronously with the main rotating wheel to drive the flat wire to move.

[0010] As a further improvement of this utility model, the support member includes a connecting plate, the two ends of which are rotatably connected to the machine base and the pressure wheel respectively, so as to maintain the stable pressure state of the pressure wheel.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The flat wire is released by the winding mechanism, the tensioning part of the lead wire mechanism adjusts the tension and forms a limiting path, the lead wire limiting wheel and lead wire groove of the lead wire limiting part restrict the width deviation of the flat wire, and the second pressing wheel and pressing guide groove of the pressing part uniformly compact the thickness of the flat wire; the main rotating wheel and the pressing wheel of the pressing mechanism, through concave-convex cooperation and spacing control, combined with the stable support of the support component, achieve efficient and continuous pressing of the flat wire.

Detailed Implementation

[0020] Specific Implementation Example 1: Please refer to Figures 1-5 A wire pressing device for flat wire includes a winding mechanism 1, a wire guiding mechanism 2, and a pressing mechanism 3. The above mechanisms are installed sequentially, and the flat wire is wound around the winding mechanism 1 and led out through the winding mechanism 1 into the wire guiding mechanism 2 and the pressing mechanism 3 to complete the wire pressing.

[0021] Specifically, the winding mechanism 1 includes a mounting base 11 and a winding roller 12. The mounting base 11 is mounted on the bottom surface, and the winding roller 12 is mounted on the mounting base 11. The winding roller 12 is rotatably connected to the mounting base 11, and the flat wire is wound around the winding roller 12.

[0022] Specifically, the lead wire mechanism 2 includes a tensioning part 21, a lead wire limiting part 22, and a pressing part 23. The tensioning part 21 is located at one end near the winding mechanism 1. The tensioning part 21 is used to adjust the tension of the flat wire. The tensioning part 21 includes a mounting frame 211, a movable arm 212, a first wheel body 213, a limiting wheel 214, a pressing wheel group 215, and a wheel group limiting groove 216. The mounting frame 211 has a hollow center, and the movable arm 212 is mounted on both sides of the mounting frame 211, and the movable arm 212 is rotatably connected to the mounting frame 211. The first wheel body 213 is mounted between the two movable arms 212, and the first wheel body 213 is rotatably connected to the two movable arms 212. The limiting wheel 214 is installed in the hollow center of the mounting frame 211, and a pair of limiting wheels 214 are provided. The limiting wheels 214 are rotatably connected to the mounting frame 211 so that the flat wire passes between the pair of limiting wheels 214 for limiting. The pressure roller assembly 215 is installed at the end of the mounting frame 211 away from the winding mechanism 1 within the cutout. The pressure roller assembly 215 has a pair of upper and lower rollers to create a limiting space for the flat wire between the two rollers. A roller limiting groove 216 is formed on the outer periphery of the middle of each roller in the pressure roller assembly 215, creating a limiting path for the flat wire to pass through on each roller. The tensioning part 21 is used to adjust the tension and path of the flat wire, allowing the flat wire to move along the path set by the tensioning part 21. The lead wire limiting part 22 is installed in the middle of the lead wire mechanism 2, and is located at the rear end of the tensioning part 21. The lead wire limiting part 22 includes multiple lead wire rollers 221 and lead wire grooves 222 correspondingly provided on each lead wire roller 221. Multiple lead-wire reels 221 are staggered (distributed in an S-shape from a top view), forming a path for the flat wire to pass through between the multiple opposing lead-wire reels 221, and this path limits the width of the flat wire. Lead-wire grooves 222 are formed at the center of the outer periphery of the corresponding lead-wire reel 221, and are circumferentially formed. The lead-wire reels 221 are rotatably connected to the lead-wire mechanism 2, so that the lead-wire reels 221 provide assistance when the flat wire passes through the path. A wire-pressing part 23 is installed at the end of the lead-wire mechanism 2, and is located at the rear end of the lead-wire limiting part 22. The wire-pressing part 23 includes second wire-pressing wheels 231 and wire-pressing guide grooves 232. Multiple second wire-pressing wheels 231 are provided, staggered and oppositely arranged, so that a path for the flat wire to pass through is formed between two opposing second wire-pressing wheels 231. The pressing guide groove 232 is formed in the middle of the outer periphery of the second pressing roller 231, and the pressing guide groove 232 is arranged around the periphery. The inner wall of the pressing guide groove 232 of each second pressing roller 231 is in contact with the flat wire, so as to limit the path of the flat wire through the staggered arrangement.

[0023] Specifically, the clamping mechanism 3 is installed at the rear end of the lead wire mechanism 2. The clamping mechanism 3 includes a base, a drive motor, a main rotating wheel 31, a driven wheel 32, a pressing wheel 33, and a support member 34. The base is located at the rear end of the lead wire mechanism 2, and the drive motor is installed on the side end of the base. The main rotating wheel 31 is mounted inside the base and is connected to the output end of the drive motor to drive the main rotating wheel 31 to rotate. A clamping groove 311 is formed around the outer circumference of the center of the main rotating wheel 31, and the clamping groove 311 matches the flat wire. The driven wheel 32 is installed on the side end of the base away from the drive motor and is fixedly connected to the main rotating wheel 31. The driven wheel 32 is rotatably connected to the end face of the base so that the main rotating wheel 31 rotates to drive the driven wheel 32. The pressure roller 33 is located at the upper end of the main rotating roller 31. A pressing protrusion 331 is circumferentially formed around the center of the pressure roller 33. The pressing protrusion 331 matches the pressing groove 311, and the distance between the pressing protrusion 331 and the pressing groove 311 is less than the thickness of the flat wire, so that the flat wire is pressed by the pressing protrusion 331 within the pressing groove 331. The support member 34 includes a plate body and a connecting plate 341. The plate body is mounted on the upper end of the machine base. The connecting plate 341 protrudes downwards on both sides within the machine base. The distal end of the connecting plate 341 is rotatably connected to the pressure roller 33, and the pressure roller 33 rotates relative to the main rotating roller 31, so that the flat wire is pressed and moved in the same direction by the pressing mechanism 3.

[0024] Working principle:

[0025] The pressing device releases the flat wire through the winding mechanism (1), and the flat wire passes through the lead wire mechanism (2) and the pressing mechanism (3) in sequence to complete the pressing. Specifically, the tensioning part (21) of the lead wire mechanism (2) adjusts the tension of the flat wire through the adjustable movable arm (212) and the pressing wheel group (215), and forms a limiting path using the wheel group limiting groove (216); the lead wire limiting part (22) limits the width of the flat wire through the staggered lead wire wheel body (221) and its lead wire groove (222); the pressing part (23) compacts the thickness of the flat wire through the relatively arranged second pressing wheel (231) and the pressing guide groove (232). The main rotating wheel (31) of the pressing mechanism (3) cooperates with the pressing wheel (33) to continuously press the flat wire by utilizing the concave-convex structure of the pressing groove (311) and the pressing protrusion (331) and the spacing smaller than the thickness of the flat wire, under the rotational cooperation of the support member (34).
