Description
Technical Field
[0001] This utility model relates to the field of textile consumables processing technology, specifically a stamping device for heddle yarn production. Background Technology
[0002] Steel heddles are a consumable material used in the production of textile fabrics. During the production process, the steel heddles need to be punched to create an opening in their body for mounting inserts. Traditional punching processes are mostly done manually, which is not only slow and inaccurate, but also labor-intensive and costly. Therefore, automated punching equipment for plastic heddles has emerged on the market.
[0003] For example, Chinese Patent Publication No. CN 222036485 U discloses a stamping device for continuous feeding of heddles. The device passes the heddles sequentially from left to right through the gaps between two clamping plates on the right, the gap between the right pressure plate and the support plate, the gap between the upper and lower molds, the gap between the left pressure plate and the support plate, and the gap between the two clamping plates on the left. Then, two cylinders are activated to drive two drive plates downwards. The two drive plates, through corresponding arc-shaped connecting rods, drive four clamping plates to rotate and clamp the heddles in the front-to-back direction. A servo motor is then activated to rotate the turntable. The turntable, through a connecting plate, drives a moving frame to the left. The moving frame, through a vertical plate and clamping plates, drives the heddles to the left. After the turntable has rotated half a circle, the servo motor stops. Two electric push rods are then activated to move the base frame downwards, and four pull rods drive two pressure plates downwards to further press and fix the heddles, ensuring a tighter clamping effect. Finally, a hydraulic cylinder is activated to move the mounting plate and the upper mold downwards, thereby stamping the heddles.
[0004] However, the existing stamping equipment for plastic heddles has a complex automatic feeding structure and is inconvenient to control the accuracy of automatic feeding, making it inconvenient for users. Utility Model Content

[0018] Example 1: Please see Figures 1-4 This utility model provides a stamping device for heddle wire production, the technical solution of which is as follows: A stamping device for producing heddles includes a workbench 1. A lower die 2 is fixedly mounted on the upper end of the workbench 1. A top plate 4 is fixedly connected to the upper end of the workbench 1 via a support column 3. A hydraulic telescopic cylinder 5 is fixedly mounted on the upper end of the top plate 4. The telescopic end of the hydraulic telescopic cylinder 5 passes through the top plate 4 and is fixedly connected to an upper die 6. Stamping grooves 7 are provided on the upper surface of the lower die 2 and the lower surface of the upper die 6. Fixed brackets 8 and movable brackets 9 are respectively provided at both ends of the upper end of the workbench 1 located at the lower die 2. A sliding block 10 is fixedly mounted on the bottom end of the movable bracket 9. The sliding block 10 is slidably mounted in a sliding groove 11.
[0019] In a preferred embodiment, a stamping head is fixedly provided at the bottom end of the upper mold 6, and a stamping hole is provided in the stamping groove 7 directly below the stamping head. A guide rod 15 is fixedly provided above the upper mold 6, and the upper end of the guide rod 15 is slidably connected to the top plate 4. The stamping head can perform stamping operations on the workpiece, and the guide rod 15 can limit the movement of the upper mold 6, making the movement of the upper mold 6 more stable.
[0020] In a preferred embodiment, the inner side of the fixing seat 8 is provided with two first arc-shaped clamping plates 16. A spring 18 is provided at the ends of the two first arc-shaped clamping plates 16 that are far apart from each other. A through hole 25 is provided at the upper end of the fixing seat 8. A downward pressing rod 19 is fixedly provided on one side of the upper mold 6. The downward pressing rod 19 is located directly above the through hole 25. A limit rod 20 is provided at the ends of the two first arc-shaped clamping plates 16 that are far apart from each other. One end of the limit rod 20 is slidably disposed on the inner wall of the fixing seat 8. The plastic heddle wire is located between the two first arc-shaped clamping plates 16. When the upper mold 6 moves downward, it can drive the downward pressing rod 19 downward. When the downward pressing rod 19 moves to a certain position, it can pass through the through hole 25 and enter the fixing seat 8. As the downward pressing rod 19 continues to descend, it can drive the first arc-shaped clamping plate 16 at the upper end of the fixing seat 8 to descend, using the first arc-shaped clamping plate 16 to press and fix the plastic heddle wire, thus achieving the fixed stamping of the plastic heddle wire.
[0021] In a preferred embodiment, two second arc-shaped clamping plates 21 are provided on the inner side of the movable clamping seat 9. The upper second arc-shaped clamping plate 21 is fixedly mounted on the telescopic end of the first electric push rod 22, which is fixedly mounted on the upper end of the movable clamping seat 9. The lower second arc-shaped clamping plate 21 is fixedly mounted on the inner wall of the movable clamping seat 9. The first electric push rod 22 drives the upper second arc-shaped clamping plate 21 to press down, thereby pressing and fixing the plastic heddle wire.
[0022] In a preferred embodiment, the inner sides of the first arc-shaped card plate 16 and the second arc-shaped card plate 21 are both provided with anti-slip textures 23, and the fixed card seat 8 and the movable card seat 9 are located on the same horizontal line. The anti-slip textures 23 can provide a better pressing effect on the plastic heddle wire.
[0023] In a preferred embodiment, a second electric push rod 24 is fixedly installed inside the slide groove 11. The telescopic end of the second electric push rod 24 is fixedly connected to the sliding block 10. The second electric push rod 24 can push the sliding block 10 to move. When the sliding block 10 moves, it can drive the plastic heddle wire to be fed.
[0024] The working principle of this utility model is as follows: In use, the plastic heddle wire is passed sequentially through the movable bracket 9, the stamping groove 7 at the upper end of the lower mold 2, and the fixed bracket 8. Then, the first electric push rod 22 is opened, which drives the second arc-shaped clamping plate 21 at the upper end of the movable bracket 9 to press down, so that the two second arc-shaped clamping plates 21 move closer to each other and clamp one end of the plastic heddle wire. After clamping one end of the plastic heddle wire, the hydraulic telescopic cylinder 5 is opened, which drives the upper mold 6 to move downward. When the upper mold 6 moves downward, it can drive the upper pressure rod 19 to move. When the upper mold 6 moves downward to a certain extent, the upper pressure rod 19 passes through the through hole 25 and the first arc-shaped clamping plate 16 at the upper end of the fixed bracket 8. As the upper mold 6 continues to descend, the two first arc-shaped clamping plates 16 move closer to each other and clamp the other end of the plastic heddle wire. Then, the stamping head on the upper mold 6 stamps the plastic heddle wire.
[0025] Example 2: Please see Figures 1-2 A toothed plate 12 is fixedly provided on one side of the upper end of the sliding block 10, and a gear 13 is meshed on one side of the toothed plate 12.

The control panel 17 is electrically connected to the measuring wheel 14, the hydraulic telescopic cylinder 3, the first electric push rod 22, and the second electric push rod 24.
[0026] After stamping, the first electric push rod 22 is opened, causing the two second arc-shaped clamping plates 21 to move away from each other. The movable clamping seat 9 releases the restriction on the plastic heddle wire. Then, the second electric push rod 24 is opened, pushing the sliding block 10 to move. When the sliding block 10 moves, it can drive the toothed plate 12 to move, thereby causing the gear 13 and the meter wheel 14 to rotate. When the preset length of the meter wheel 14 is reached, the control panel 17 closes the second electric push rod 24. Then, the hydraulic telescopic cylinder 5 is opened to drive the upper mold 6 to move upward. The upper pressure rod 19 separates from the first arc-shaped clamping plate 16, and the fixed clamping seat 8 releases the fixation on one end of the plastic heddle wire. Then, the first electric push rod 22 is used to drive the second arc-shaped clamping plate 21 to fix one end of the plastic heddle wire again. The second electric push rod 24 is opened, pulling the sliding block 10 and the movable clamping seat 9 to move. Thus, the movable clamping seat 9 drives the plastic heddle wire to move, realizing the automatic quantitative feeding of the plastic heddle wire.
