Description

Technical Field

[0001] This utility model relates to the fields of mechanical manufacturing and metal processing, and in particular to a drawing device for the production of hand sewing needles. Background Technology

[0002] The drawing device used in the production of hand sewing needles is the core equipment in the hand sewing needle manufacturing process to achieve precise reduction of the diameter of the metal wire and preliminary shaping of its shape. By forcing a metal wire through a series of progressively narrowing, hard die holes with powerful tensile force, its diameter is precisely compressed and reduced. Simultaneously, the internal crystalline structure becomes denser and more fibrous, significantly improving the wire's strength, hardness, surface finish, and straightness. This equipment is a crucial foundation for the front end of hand-sewing needle manufacturing, providing qualified raw materials for subsequent processes such as sharpening, needle eye stamping, and polishing, directly determining the final sewing needle's mechanical properties, durability, and quality. In existing technologies, the diameter of the drawn metal wire is extremely fine (usually only the basic thickness of the finished hand sewing needle). When handled manually, the wire is prone to slipping and bending, which not only wastes raw materials but also causes the operator's hands to be scratched due to the wire's bounce, posing a safety hazard. Therefore, a drawing device for hand sewing needle production is proposed to solve the above problems. Utility Model Content

[0010] Reference Figures 1 to 3 The present invention provides an embodiment of a drawing device for hand sewing needle production, comprising a main body 1, wherein a clamping mechanism 4 is slidably connected inside the main body 1, the clamping mechanism 4 can stably clamp the metal wire and realize the drawing action, ensuring that the wire maintains a stable posture during the drawing process; a feeding mechanism 2 is fixedly connected to the top of the main body 1, the feeding mechanism 2 can efficiently complete the gripping and transfer of the wire after drawing, improving the feeding efficiency; a quick-release mechanism 3 is fixedly connected to the outside of the main body 1, the mechanism can quickly realize the disassembly and assembly of related components, facilitating maintenance and replacement; and a processing table 5 is fixedly connected to the top of the main body 1, used for pre-processing the wire before drawing and guiding it during drawing. The unloading mechanism 2 includes an electric slide 21, which provides power and guidance for the movement of the slide plate 22, ensuring its smoothness and precision. The bottom of the electric slide 21 is fixedly connected to the top of the main body 1. The slide plate 22 is slidably connected inside the electric slide 21. The slide plate 22 can drive the connected components below to move horizontally, achieving position adjustment. An auxiliary plate 23 is fixedly connected to the bottom of the slide plate 22. The auxiliary plate 23 acts as a pneumatic cylinder 24, providing fixation and support, enhancing structural stability. A pneumatic cylinder 24 is fixedly connected to the bottom of the auxiliary plate 23, providing vertical driving force to drive the components below to rise and fall. The drive end of the pneumatic cylinder 24 is fixedly connected to... The connecting plate 25 can transmit the driving force of the pneumatic cylinder 24 to the connecting plate 26. The two ends of the connecting plate 25 are fixedly connected to the connecting plate 26. The connecting plate 26 can drive the rotating plate 27 to move, thereby controlling the opening and closing of the clamp 28. There are two rotating plates 27 rotatably connected inside the connecting plate 26. The rotating plates 27 can change the angle and position of the clamp 28 by rotating, so that it can better complete the clamping action. The clamp 28 is rotatably connected inside the rotating plate 27. The clamp 28 is a component that directly contacts the wire and realizes clamping. It can stably grasp the wire. The auxiliary block 29 is fixedly connected inside the clamp 28. The auxiliary block 29 can enhance the clamping force of the clamp 28 on the wire and prevent the wire from slipping. The auxiliary block 29 includes 291, which can enhance the friction between the clamp 28 and the wire and improve the stability of clamping. The external fixed connection of 291 is to the outside of the clamp 28. The internal rotatable connection of the clamp 28 is a connecting rod 292, which can limit and guide the rotation of the clamp 28, making the opening and closing action of the clamp 28 more precise. The external fixed connection of the slide plate 22 is an auxiliary rod 293, which provides a fixed fulcrum for the connecting rod 292 and ensures the stability of the position of the connecting rod 292. The external part of the connecting rod 292 is fixed inside the auxiliary rod 293. This fixing method can ensure that the connecting rod 292 does not shift during operation, providing stable support for the movement of the clamp 28. The external part of the rotating plate 27 is slidably connected to the external part of the connecting plate 25, so that the rotating plate 27 can slide and rotate smoothly under the drive of the connecting plate 25, ensuring the normal operation of the clamp 28. Reference Figure 1 , Figure 2 and Figure 4The quick-release mechanism 3 includes an auxiliary platform 31, which provides an installation base for other components of the quick-release mechanism 3, ensuring the stability of the overall structure. The auxiliary platform 31 is externally fixed to the outside of the main body 1. A fixing plate 32 is fixedly connected to the top of the auxiliary platform 31. The fixing plate 32 is used to fix the fixing rod 33 to keep its position stable. The fixing rod 33 is externally fixed to the fixing plate 32, providing installation space and support for the pneumatic cylinder 34. The pneumatic cylinder 34 is internally fixed to the fixing rod 33. The pneumatic cylinder 34 is the quick-release mechanism. The power source of mechanism 3 can drive the slider 35 to move. The drive end of the pneumatic cylinder 2 34 is fixedly connected to the slider 35. The slider 35 can transmit the power of the pneumatic cylinder 2 34 to the sliding ring 36, causing it to move. The external side of the slider 35 is fixedly connected to the sliding ring 36. The movement of the sliding ring 36 can drive the fixed block 37 to move, thereby controlling the state of the support plate 1 38. The external side of the sliding ring 36 is fixedly connected to multiple fixed blocks 37. The fixed blocks 37 serve to connect the sliding ring 36 and the support plate 1 38, converting the movement of the sliding ring 36 into the rotation of the support plate 1 38. The fixed block 37 is externally rotatably connected to two support plates 38. The support plates 38 can change their own angle by rotating, thereby driving the connecting block 39 and the second support plate 310 to move. The other end of the support plate 38 is rotatably connected to the connecting block 39. The connecting block 39 can coordinate the movement of the two support plates 38, so that the second support plate 310 can move smoothly. The other end of the connecting block 39 is fixedly connected to the second support plate 310. The second support plate 310 can lift or lower the fixed cylinder 311 during the movement, so as to realize the quick assembly and disassembly of the fixed cylinder 311. The second support plate 310 is externally connected to a fixed cylinder 311, which is used to fix the drawing die. It can be quickly replaced by the movement of the second support plate 310, improving maintenance efficiency. The first support plate 38 is externally slidably connected to the outside of the sliding ring 36. This connection method can ensure that the first support plate 38 can rotate smoothly when the sliding ring 36 moves, ensuring the normal operation of the quick release mechanism 3. Reference Figure 1 and Figure 2 The clamping mechanism 4 includes a sliding base 43, which can drive the upper component to slide inside the main body 1 to realize the pulling action of the wire. The sliding base 43 is slidably connected inside the main body 1. A fixing plate 2 42 is fixedly connected to the top of the sliding base 43. The fixing plate 2 42 is used to fix and support the motor 41 and the clamp 2 44 to ensure their stable position. The second fixing plate 42 is externally slidably connected to a second clamp 44. The second clamp 44 can clamp the wire under the drive of the motor 41 and move with the sliding base 43 to complete the pulling. The other end of the second fixing plate 42 is fixedly connected to a motor 41. The motor 41 provides power for the clamping action of the second clamp 44 to ensure that it can stably clamp the wire.

[0011] Working principle: When the drawing device is working, the drawing die is first installed and fixed by the quick release mechanism 3: start the pneumatic cylinder 34, drive the slider 35 to move along the fixed rod 33, drive the sliding ring 36 to slide synchronously, so that the fixed block 37 pulls the support plate 38 to rotate around the fixed block 37 as the fulcrum, and transmit the force to the support plate 310 through the connecting block 39, so that it opens the fixed cylinder 311. After the die is put in, the reverse operation can be used to complete the fixing, which is convenient for quick replacement of dies of different specifications.

[0012] During the pulling process, after the hand sewing needle thread is guided by the processing table 5, the motor 41 drives the clamp 44 to close and hold the thread, and the sliding base 43 slides along the inside of the main body 1, driving the thread through the mold to complete the pulling. After pulling, the thread is cut off.

[0013] Then the unloading mechanism 2 is activated: the electric slide 21 drives the slide plate 22 to move to the designated position, the pneumatic cylinder 24 pushes the connecting plate 25 down, so that the connecting plate 26 drives the rotating plate 27 to rotate, and at the same time the connecting rod 292 pulls the clamp 28 under the limit of the auxiliary rod 293, and the auxiliary block 291 accurately clamps the wire. Finally, the slide plate 22 moves to transfer the wire to the collection point, realizing automated unloading.
