[0002] As a representative steel type of ferritic stainless steel, 430 stainless steel has the characteristics of good corrosion resistance, oxidation resistance, low thermal expansion rate and good thermal conductivity. In addition, 430 stainless steel also shows good thermal fatigue resistance and mechanical properties of weld parts, which makes it widely used in many fields. Especially in occasions that require certain corrosion resistance and mechanical strength, such as architectural decoration, home appliance parts, chemical equipment, fuel burner parts and household appliances, 430 stainless steel shows its unique advantages. In textile machinery, 430 stainless steel is often used to make reed wires, which not only need to have sufficient strength and corrosion resistance, but also require a smooth surface to reduce friction and wear and increase service life.

[0003] The linear drawing of stainless steel reed wire is an important metal plastic processing method. It pulls the stainless steel billet out of a die hole smaller than the billet section under the action of the drawing force to obtain a product of the desired shape and size. This method can not only improve the mechanical properties and surface quality of the material, but also meet the requirements of the material shape and size for specific applications. In the production process of stainless steel reed wire, the linear drawing technology is particularly important because it is directly related to the straightness, surface finish and overall quality of the product.

[0010] Preferably, a limiting sliding groove is formed through the connecting triangle plate, a fixed block is fixed on the outer side between the two fixed vertical plates at each end, the fixed block slides along the limiting sliding groove, and a pressure spring is fixed inside the limiting sliding groove along one side of the fixed block.

[0011] Preferably, the lower support frame comprises a bottom bracket, an inner end surface of the bottom bracket is provided with a collecting groove, and a return pipe is installed on one side of the bottom bracket along the inclined direction of the collecting groove.

[0012] Preferably, the lower support frame further includes an upper bracket, and the cross direction between the upper bracket and the bottom bracket is fixed by a vertical bracket.

[0013] Preferably, a weight-reducing groove is formed through the mold body, and a limiting sliding member is fixed to the front and rear ends of the mold body. The limiting sliding member slides along the sliding groove on the upper bracket and is clamped and fixed by a fixed clamping member.

[0015] A stainless steel reed wire straight line drawing bright surface process, comprising the following steps: Step 1: The stainless steel billet is pulled through the input conveying roller, the lubrication channel on the rough drawing die, the transition channel on the rough drawing die, the drawing channel on the rough drawing die, the lubrication channel on the fine drawing die, the transition channel on the fine drawing die, the drawing channel on the fine drawing die, the lubrication channel on the shaping die, the transition channel on the shaping die, the drawing channel on the shaping die and the output conveying roller in sequence; Step 2: The water-based composite lubricant is pumped by the external pumping structure, passes through the lubricant inlet pipe, the delivery hose, the C-shaped distribution pipe, the longitudinal distribution pipe and the spray branch pipe in sequence, and then sprayed from the lubricant nozzle, sprayed on the upper and lower surfaces of the stainless steel billet to form a uniform film layer; Step 3: After lubrication, the stainless steel blank enters the drawing channel. The drawing channels of the rough drawing die and the fine drawing die gradually reduce the size of the stainless steel blank, and the drawing channel of the shaping die reduces the drawing surface roughness of the stainless steel blank. Step 4: The polishing conveyor roller polishes the stainless steel blank led out from the drawing channel.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) In this invention, a three-level die set of a rough drawing die, a fine drawing die and a shaping die is used, and the drawing channels on the rough drawing die and the fine drawing die are channels with gradually decreasing apertures. The inlet angle of the drawing channel on the rough drawing die is greater than the inlet angle of the drawing channel on the fine drawing die, and the aperture of the drawing channel on the shaping die remains consistent, so that the force acting on the stainless steel billet gradually increases each time it is drawn, avoiding a single drawing transition. In addition, a water-based composite lubricant is sprayed at the lubrication channel position. By optimizing the die design and the lubricant spraying system, continuous drawing and surface brightening treatment of the wire are achieved, significantly improving the yield and quality of the wire. This solves the problem that the stainless steel reed wire needs to be pulled out from a die hole smaller than the cross section of the billet during the drawing process, and the die will have a certain impact on the billet surface, resulting in the surface not being smooth and flat.

[0017] (2) In the present invention, after the stainless steel blank is drawn in the drawing channels of the rough drawing die, the fine drawing die and the shaping die, it passes through two polishing conveying rollers. The two polishing conveying rollers polish the upper and lower end surfaces of the drawn stainless steel blank, thereby further improving the surface smoothness.

[0018] (3) In the present invention, a safety limit unit and a limit sliding design of the polishing conveyor roller are introduced. When the stainless steel billet breaks, the polishing conveyor roller loses its force and rotates toward the input direction under the action of the pressure spring. At the same time, the two polishing conveyor rollers rotate inward under the action of the torsion spring, driving the action limit plate to rotate. The inclined limit surface moves toward the direction of the stainless steel billet, pressing the stainless steel billet to avoid the situation where the two ends of the broken side of the stainless steel billet are subjected to force during the drawing fracture, causing the stainless steel billet to move disorderly. This effectively prevents the occurrence of unexpected situations after the wire breaks and improves the safety of the production process. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] See also Figure 1-Figure 7 , an embodiment provided by the present invention: (1) Lower support frame and three-stage mold assembly, such as Figure 1-Figure 5 As shown: The design of the input conveying roller 7 and the output conveying roller 8 realizes the automatic input and output of the wire and improves the production efficiency.

[0023] A lower support frame 1 is designed, and a rough drawing die 9, a fine drawing die 10 and a shaping die 11 are integrated inside. The three have the same structure but different functions, and are used for preliminary drawing, fine drawing and final shaping of the wire respectively. A lubrication channel 14, a transition channel 15 and a drawing channel 16 are cleverly designed inside the die body 12. The lubrication channel 14, the transition channel 15 and the drawing channel 16 are connected. The drawing channels 16 on the rough drawing die 9 and the fine drawing die 10 are channels with gradually decreasing apertures. The inlet angle of the drawing channel 16 on the rough drawing die 9 is greater than the inlet angle of the drawing channel 16 on the fine drawing die 10, and the aperture of the drawing channel 16 on the shaping die 11 remains consistent; ensuring that the wire is fully lubricated and drawn multiple times during the drawing process, reducing friction and wear.

[0024] Lubricant nozzles 24 are installed in an array from front to back along the upper and lower ends of the lubrication channel 14 on the die body 12. The outer ends of the lubricant nozzles 24 are connected to spray branch pipes 23. The other ends of the multiple spray branch pipes 23 at each end extend outward and are commonly connected to the longitudinal distribution pipe 22. Each group of two longitudinal distribution pipes 22 are connected to the two ends of the C-shaped distribution pipe 21. The rear ends of the three C-shaped distribution pipes 21 are commonly connected to the delivery hose 20, and the rear end of the delivery hose 20 is connected to the lubricant inlet pipe 19. The lubricant nozzles 24 evenly spray lubricant through the multi-stage distribution pipes to ensure that a uniform film layer is formed on the surface of the wire, significantly improve the drawing effect, reduce the roughness of the wire surface, and at the same time ensure the uniform distribution of the lubricant, extending the service life of the die.

[0025] A 430 stainless steel reed wire straight line drawing bright surface process, comprising the following steps: Step 1: The stainless steel blank is pulled through the input conveying roller 7, the lubrication channel 14 on the rough drawing die 9, the transition channel 15 on the rough drawing die 9, the drawing channel 16 on the rough drawing die 9, the lubrication channel 14 on the fine drawing die 10, the transition channel 15 on the fine drawing die 10, the drawing channel 16 on the fine drawing die 10, the lubrication channel 14 on the shaping die 11, the transition channel 15 on the shaping die 11, the drawing channel 16 on the shaping die 11 and the output conveying roller 8 in sequence; Step 2: The water-based composite lubricant is pumped by the external pumping structure, passes through the lubricant inlet pipe 19, the delivery hose 20, the C-shaped distribution pipe 21, the longitudinal distribution pipe 22 and the spray branch pipe 23 in sequence, and then sprayed from the lubricant nozzle 24, sprayed on the upper and lower surfaces of the stainless steel blank, forming a uniform film layer; Step 3: The stainless steel blank enters the drawing channel 16 after lubrication. The drawing channels 16 of the rough drawing die 9 and the fine drawing die 10 gradually reduce the size of the stainless steel blank, and the drawing channel 16 of the shaping die 11 reduces the drawing surface roughness of the stainless steel blank. Step 4: Polishing The conveying roller 32 polishes the stainless steel blank drawn out from the drawing channel 16 .

[0026] (2) Safety limit unit, such as Figure 1 , Figure 4 , Figure 6 and Figure 7 As shown: The safety limit unit 25 is introduced, including a fixed bracket 35, an intermediate fixed frame 36, an action limit plate 37 and other components. The two ends of the fixed bracket 35 are welded and fixed to the upper and lower ends of the lubrication channel 14 on one side of the mold body 12. The fixed bracket 35 is connected with an intermediate fixed frame 36 from front to back. The upper and lower ends of the intermediate fixed frame 36 are connected with an action limit plate 37 through an axis rotation. It can respond quickly when the wire breaks to prevent the broken wire from splashing and causing safety hazards. The action limit plate 37 forms an inclined limit surface 38 in the direction of the lubrication channel 14. A clamping plate is fixed on the inclined limit surface 38. The inclined limit surface 38 and the clamping plate design on the action limit plate 37 can clamp the wire when the wire breaks to prevent it from continuing to move, effectively improving the safety of the production process and reducing the risk of safety accidents caused by wire breakage.

[0027] Four fixed vertical plates 26 are welded and fixed at the front and rear ends of the other side of the mold body 12. A connecting triangular plate 29 is arranged between the two fixed vertical plates 26 at each end. Polishing conveying rollers 32 are arranged at the upper and lower ends between the two connecting triangular plates 29, which can polish the wire during the wire drawing process to further improve the surface quality of the wire.

[0029] A limiting sliding groove 30 is formed through the connecting triangle plate 29, and a fixed block 27 is fixed on the outer side between the two fixed vertical plates 26 at each end. The fixed block 27 slides along the limiting sliding groove 30, and a pressure spring 28 is fixed inside the limiting sliding groove 30 along one side of the fixed block 27. The existence of the pressure spring 28 allows the connecting triangle plate 29 to slide relative to the fixed vertical plate 26, matching the rotation of the action limiting plate 37.

[0030] A safety limiting method for linear drawing of a 430 stainless steel reed wire comprises the following steps: Step 1: During the drawing process, the stainless steel blank exerts a force on the polishing conveying roller 32, so that the polishing conveying roller 32 moves in the drawing direction under the limiting sliding relationship between the limiting sliding groove 30 and the fixed block 27, and at the same time, each group of two polishing conveying rollers 32 rotate outward under the drawing action of the stainless steel blank; Step 2: The action limiting plate 37 is driven to rotate to a horizontal state through the connection between the first central axis 31, the vertical connecting plate 34 and the second central axis 39; Step 3: When the stainless steel blank breaks during the drawing process, the polishing conveying roller 32 loses its force, and the polishing conveying roller 32 rotates toward the input direction under the action of the pressure spring 28, and at the same time, the two polishing conveying rollers 32 rotate inward under the action of the torsion spring 33; Step 4: The action limiting plate 37 is driven to rotate by connecting the first central axis 31, the vertical connecting plate 34 and the second central axis 39, and the inclined limiting surface 38 moves toward the direction of the stainless steel blank to press the stainless steel blank; Step 5: While the action limiting plate 37 rotates to press the stainless steel blank, the presence of the pressure spring 28 causes the connecting triangle plate 29 to slide relative to the fixed vertical plate 26 to match the rotation of the action limiting plate 37 .

[0031] (3) Other basic structures, such as Figure 1-Figure 3 As shown: The bottom bracket 2, the collecting tank 3 and the reflux pipe 4 are designed to collect the excess lubricant dripping during the drawing process to achieve the recycling of resources.
