Description

Technical Field

[0001] The present application relates to the technical field of automobile parts, and specifically to an automobile decorative strip, a processing method and processing equipment. Background Art

[0002] At present, with the development of social economy, vehicles are no longer just a simple means of transportation, and their social attributes are becoming more and more obvious. A set of beautiful interior and exterior decoration can effectively improve the grade of the vehicle and increase the riding experience of the driver and passengers. Therefore, many cars will have a variety of decorative designs. For example, stainless steel car decorative strips are added to the outer edge of the window, making the side of the car body more beautiful and elegant.

[0003] In the prior art, stainless steel automobile decorative strips are generally fixed with double-sided tape. However, this fixing method has the following main defects: (1) Before the finished automobile decorative strips are packaged, they need to be glued, that is, workers need to manually stick one side of the double-sided tape on the back of the automobile decorative strips. Especially for automobile decorative strips located at the triangular window of the car, their shapes are irregular, which makes the double-sided tape unable to be arranged in a straight line, that is, the double-sided tape needs to be cut at the corners. The gluing operation has many steps and low production efficiency. Moreover, the uniformity of the glue sticking is uneven, which makes consumers have the first impression of poor workmanship, seriously affecting the consumer experience and increasing the rate of negative reviews. (2) Because the double-sided tape at the corners of the automobile decorative strips is cut off, it is easy to cause water or dust to enter the corners on the back of the automobile decorative strips during later use, which can easily affect the viscosity of the double-sided tape, and in severe cases, it may even cause the automobile decorative strips to fall off. (3) Since the car decorative strips are fixed by double-sided tape, the alignment accuracy of the car decorative strips must be ensured during installation, and hand shaking must not occur, which makes installation difficult. Otherwise, once there is an error in the installation position, it will be difficult to perform a secondary installation, which is very inconvenient for novice operators. (4) Before the stainless steel car decorative strips are stamped and formed, the 3mm thick stainless steel raw materials need to be repeatedly stretched, alkali washed and annealed to obtain a stainless steel blank with a thickness of 0.3mm to 0.6mm. Among them, during the last annealing process, the thickness of the stainless steel blank is only 0.3mm to 0.6mm. When heated by the heating coil, the stainless steel blank is prone to bending deformation, which leads to a reduction in the local thickness of the stainless steel blank, and then local damage is prone to occur during stamping, resulting in a high scrap rate.

When punching after leveling, no waste will occur due to uneven thickness, and the yield rate of the automotive decorative strip is fully improved. BRIEF DESCRIPTION OF THE DRAWINGS

Compared with the traditional installation method, this installation method does not need to use double-sided tape, thereby avoiding various adverse effects caused by the use of double-sided tape, which is beneficial to improving production efficiency and reducing the rate of bad reviews from consumers.

[0051] Reference Figure 3The present application also provides a processing device for processing the above-mentioned automobile decorative strips, including a stretching mechanism, a traction mechanism 1, a bending mechanism 2, a heating mechanism 3, a conveying mechanism 4, a flattening mechanism 5, a punching mechanism, a stamping mechanism and a bending mechanism arranged in sequence from left to right; the stretching mechanism is used to stretch the stainless steel raw material into a stainless steel coil 200 of target thickness, the traction mechanism 1 is used to pull the stainless steel coil 200 to the right through the bending mechanism 2; the bending mechanism 2 is used to bend the stainless steel coil 200 along the width direction to form a wavy structure without changing the thickness of the stainless steel coil 200; the heating mechanism 3, the conveying mechanism 4, the flattening mechanism 5, the punching mechanism, the punching mechanism and the bending mechanism; the stretching mechanism is used to stretch the stainless steel raw material into a stainless steel coil 200 of target thickness, the traction mechanism 1 is used to pull the stainless steel coil 200 to the right through the bending mechanism 2; the bending mechanism 2 is used to bend the stainless steel coil 200 along the width direction to form a wavy structure without changing the thickness of the stainless steel coil 200; The heating mechanism 3 is used to heat the wavy structure, the conveying mechanism 4 is used to convey the heated wavy structure to the flattening mechanism 5, and the wavy structure is gradually cooled on the conveying mechanism 4; the flattening mechanism 5 is used to fully flatten the wavy structure to form a blank without changing the thickness of the wavy structure; the punching mechanism is used to punch the blank to form a decorative strip body 100, and at the same time extend one side of the decorative strip body 100 to form a straight extension section; the stamping mechanism is used to stamp out a protrusion 102 on the side wall of the decorative strip body 100, and the bending mechanism is used to bend the extension section to form a plug-in portion 101.

[0052] Reference Figure 4 as well as Figure 5 In some embodiments of the present application, the traction mechanism 1 includes a base 11, two lower brackets 12, two upper brackets 13, at least one lower traction roller 14, at least one upper traction roller 15 and at least two first elastic members 16; the two lower brackets 12 are symmetrically arranged on the base 11 front and back, and the two upper brackets 13 can be slidably connected to the two lower brackets 12 up and down respectively; the two ends of the lower traction roller 14 can be rotatably connected to the two lower brackets 12 respectively, and the two ends of the upper traction roller 15 can be rotatably connected to the two upper brackets 13 respectively; at least one first elastic member 16 is provided between the upper bracket 13 and the lower bracket 12, and the first elastic member 16 is used to make the upper bracket 13 slide downward, so that the stainless steel coil 200 is clamped between the upper traction roller 15 and the lower traction roller 14, so that the stainless steel coil 200 can be moved to the right by rotating the upper traction roller 15 and / or the lower traction roller 14. Among them, the method of driving the upper traction roller 15 or the lower traction roller 14 to rotate is the existing technology, for example, a driving motor is set at one end of the upper traction roller 15 or the lower traction roller 14, and the upper traction roller 15 or the lower traction roller 14 is driven to rotate by the output shaft of the driving motor; or other driving structures are used, which are not illustrated here one by one.

[0053] The specific working principle of the traction mechanism 1 is as follows: Figure 5As shown, the stainless steel coil 200 is passed from left to right between the upper traction roller 15 and the lower traction roller 14. Under the elastic force of the first elastic member 16, the upper bracket 13 (i.e., the upper traction roller 15) slides downward, so that the stainless steel coil 200 is clamped between the upper traction roller 15 and the lower traction roller 14. When the upper traction roller 15 or the lower traction roller 14 is driven to rotate, the stainless steel coil 200 can be moved to the right. In addition, since the first elastic member 16 can be compressed, the upper bracket 13 (i.e., the upper traction roller 15) is allowed to move upward during actual operation, so as to prevent the stainless steel coil 200 from being stuck between the upper traction roller 15 and the lower traction roller 14 due to deformation along its width (i.e., front and back) direction. Otherwise, if the upper traction roller 15 is not allowed to move upward, and the stainless steel coil 200 is deformed along its width direction under the action of the bending mechanism 2 on the right side of the traction mechanism 1, the deformation is likely to cause the stainless steel coil 200 at the position of the traction mechanism 1 to also produce local deformation, and the local deformation will cause the stainless steel coil 200 to increase in thickness, so that it is easy to get stuck between the upper traction roller 15 and the lower traction roller 14. Under the action of the first elastic member 16, even if local deformation occurs and the size in the local thickness direction increases, the upper traction roller 15 can further compress the first elastic member 16 through the upper bracket 13, so that the upper traction roller 15 slides upward to match the size change in the thickness direction. Of course, this upward sliding feature of the upper traction roller 15 can also be used to traction stainless steel coils 200 of different thicknesses. In addition, since the upper traction roller 15 needs to be allowed to slide upward, the pressure of the first elastic member 16 on the upper bracket 13 cannot be too large, which will inevitably lead to insufficient friction between the stainless steel coil 200 and the upper traction roller 15 and the lower traction roller 14, thereby affecting the reduction of the traction force on the stainless steel coil 200. For this reason, a rubber sleeve made of elastic material (such as rubber) can be sleeved on the upper traction roller 15 and the lower traction roller 14 to increase the friction between the stainless steel coil 200 and the rubber sleeve, so that sufficient traction is generated on the stainless steel coil 200. Moreover, the multiple upper traction rollers 15 and the multiple lower traction rollers 14 can not only improve the traction force on the stainless steel coil 200, but also fully reduce the influence of the bending mechanism 2 on the left side of the traction mechanism 1 on the tying operation of the tying mechanism 1 when the bending mechanism 2 on the right side of the traction mechanism 1 performs the bending operation.

[0054] In order to adjust the pressure of the first elastic member 16 on the upper bracket 13, Figure 5 and Figure 6As shown, a guide column 121 is provided on the lower bracket 12, and the upper bracket 13 is slidably connected to the guide column 121 up and down; the first elastic member 16 includes a spring 161 and an adjusting bolt 162, and the adjusting bolt 162 penetrates the upper bracket 13 and is then threadedly connected to the lower bracket 12; the spring 161 is sleeved on the adjusting bolt 162, and the spring 161 is located between the upper bracket 13 and the large head end of the adjusting bolt 162; when the adjusting bolt 162 is rotated, the initial compression amount of the spring 161 can be changed, thereby generating different pressure effects on the upper bracket 13.

[0055] Reference Figure 5 as well as Figure 6 In some embodiments of the present application, the traction mechanism 1 also includes a support member 17, the upper end of the support member 17 is hinged to the lower bracket 12, and the lower end of the support member 17 is protruded with a clamping portion 171; a stopper portion 131 is provided at a position corresponding to the support member 17 on the upper bracket 13, and a clamping groove 132 is provided on the lower end surface of the stopper portion 131; when the upper bracket 13 is forced to slide upward by external force and the support member 17 is rotated upward until the clamping portion 171 is clamped in the clamping groove 132, the upper bracket 13 is restricted from sliding downward, and the gap between the upper traction roller 15 and the lower traction roller 14 is greater than the thickness of the stainless steel coil 200. When a stainless steel coil 200 needs to be replaced after using it, the upper bracket 13 is lifted upward by external force, and the propping member 17 is rotated upward, so that the clamping portion 171 is clamped in the clamping groove 132, so that the gap between the upper traction roller 15 and the lower traction roller 14 is increased, so that it is convenient to pass the starting end of the stainless steel coil 200 through the upper traction roller 15 and the lower traction roller 14, which not only reduces the difficulty of the coil replacement operation, but also avoids the operator's fingers being pinched during the coil replacement operation; and after completing the coil replacement, it is only necessary to lift the upper bracket 13 upward, rotate the propping member 17 downward, and then slowly put down the upper bracket 13. In other words, the pressure of the first elastic member 16 (i.e., spring 161) on the upper bracket 13 will not be changed after the coil replacement operation, and there is no need to readjust it.

[0056] Reference Figures 7 to 9 as well as Figures 13 to 17In some embodiments of the present application, the bending mechanism 2 includes a fixed frame 21 and a plurality of bending components 22 arranged in sequence from left to right; each bending component 22 includes an upper roller body 221, a lower roller body 222, a first roller 223 and a second roller 224, and the front and rear ends of the upper roller body 221 and the lower roller body 222 are rotatably arranged on the fixed frame 21, and the gap between the upper roller body 221 and the lower roller body 222 is greater than the thickness of the stainless steel coil 200; the first roller 223 is coaxially arranged in the middle of the upper roller body 221, and the second roller 224 is coaxially arranged in the middle of the lower roller body 222 (wherein, the positions of the first roller 223 and the second roller 224 can be The outer ring surface of the second roller 224 is coaxially provided with an annular groove 2241, and a V-shaped area is formed between the annular groove 2241 and the corresponding first roller 223, and the gap of the V-shaped area is greater than the thickness of the stainless steel coil 200; the number of the first roller 223 and the second roller 224 on the leftmost bending assembly 22 is one, and the number of the first roller 223 and the second roller 224 on each bending assembly 22 from left to right increases by two; a clamping wheel 225 is coaxially provided between the two adjacent first rollers 223, and the clamping wheel 225 and the corresponding two second rollers 224 are suitable for clamping the stainless steel coil 200. Among them, the method of driving the upper roller body 221 and the lower roller body 222 to rotate is the existing technology, for example, the same as the method of driving the upper traction roller 15 to rotate, and will not be described in detail here.

[0057] The specific working principle of the bending mechanism 2: When the stainless steel coil 200 passes through ( Figure 7 ) When the leftmost bending component 22 is Fig.14 and Fig.15 As shown, under the action of the first roller 223 and the annular groove 2241 on the second roller 224, a V-shaped structural deformation will be generated in the middle of the stainless steel coil 200; because the gap between the upper roller body 221 and the lower roller body 222 and the gap in the V-shaped area are greater than the thickness D of the stainless steel coil 200, during the deformation process, the two sides of the stainless steel coil 200 are displaced toward the middle, so the thickness of the stainless steel coil 200 itself will not be changed.

[0058] Similarly, when the stainless steel coil 200 then passes through ( Figure 7 ) when a bending component 22 is in the middle, such as Fig.16 and Fig.17As shown, the V-shaped area formed between a first roller 223 and a second roller 224 located in the middle just fits the deformation of a V-shaped structure in the middle of the stainless steel coil 200; at the same time, under the action of the other two first rollers 223 and the other two second rollers 224, two new V-shaped structural deformations can be further generated on the passing stainless steel coil 200; in addition, since the gap between the upper roller body 221 and the lower roller body 222 and the gap in the V-shaped area are both greater than the thickness D of the stainless steel coil 200, but under the action of the clamping wheel 225, that is, the clamping wheel 225 and the corresponding two second rollers 224 can just clamp the stainless steel coil 200, that is, when a new V-shaped structural deformation is generated, only the two sides of the stainless steel coil 200 can be further displaced toward the middle, so the thickness of the stainless steel coil 200 itself will not be changed. By analogy, after the stainless steel coil 200 passes through each bending assembly 22 from left to right in sequence, the stainless steel coil 200 can be bent along its width direction to form a wavy structure without changing its own thickness, thereby increasing its strength and preventing it from bending and deforming when passing through the heating mechanism 3.

[0059] Reference Figures 7 to 11 In some embodiments of the present application, in order to facilitate the adjustment of the gap between the upper roller body 221 and the lower roller body 222, the bending mechanism 2 also includes a first positioning assembly 23, the first positioning assembly 23 includes an upper positioning block 231, a lower positioning block 232, a limit block 233, an adjusting bolt 234 and a second elastic member 235; the two ends of the upper roller body 221 are rotatably connected to the two upper positioning blocks 231, and the two ends of the lower roller body 222 are rotatably connected to the two lower positioning blocks 232; the upper positioning block 231 and the lower positioning block 232 are respectively slidable up and down and connected to the fixed The fixed frame 21 and the upper position of the corresponding upper adjustment block 231 on the fixed frame 21 are both threadedly connected with an adjustment bolt 234, and the lower position of the corresponding lower adjustment block 232 on the fixed frame 21 is provided with a limit block 233; at least one second elastic member 235 is provided between the corresponding upper adjustment block 231 and the lower adjustment block 232, so that the corresponding upper adjustment block 231 and the lower adjustment block 232 slide in opposite directions through the second elastic member 235 until the upper adjustment block 231 slides upward to contact the adjustment bolt 234, and the lower adjustment block 232 slides downward to contact the limit block 233. Figure 7As shown, since the lower end of the lower adjusting block abuts against the limit block 233, the lower adjusting block (i.e., the lower roller body 222) cannot continue to slide downward; therefore, when the adjusting bolt 162 continues to be tightened, the adjusting bolt 162 pushes the upper adjusting block 231 (i.e., the upper roller body 221) to slide downward, thereby reducing the gap between the upper roller body 221 and the lower roller body 222; similarly, when the adjusting bolt 162 is loosened, under the action of the second elastic member 235, the upper adjusting block 231 (i.e., the upper roller body 221) slides upward, thereby increasing the gap between the upper roller body 221 and the lower roller body 222.

[0060] Reference Figure 7 , Fig.11 , Fig.12 , Fig.16 as well as Fig.18 In some embodiments of the present application, in order to facilitate the stainless steel coil 200 to pass through the upper roller body 221 and the lower roller body 222 when changing the coil, the lower end of the lower adjustment block 232 is provided with a first inclined surface 2321; the limit block 233 can be slidably connected to the fixing frame 21 forward and backward, and the limit block 233 is provided with a second inclined surface 2331 for adapting to the first inclined surface 2321; the first adjustment assembly 23 also includes a driving member 236, and the driving member 236 is used to drive the limit block 233 to slide forward and backward; when the driving member 236 drives When the movable limit block 233 slides away from the lower adjustment block 232 until it is separated from the lower adjustment block 232, the second elastic member 235 forces the lower adjustment block 232 to slide downward, thereby increasing the gap between the upper roller body 221 and the lower roller body 222; when the driving member 236 drives the limit block 233 to slide toward the lower adjustment block 232, the second inclined surface 2331 forces the lower adjustment block 232 to slide upward through the first inclined surface 2321 until the limit block 233 is supported on the lower end of the lower adjustment block 232. Fig.16 and Fig.18 As shown, when changing the roll, the limit block 233 is driven by the driving member 236 to slide in the direction away from the lower adjustment block 232 until the limit block 233 is separated from the lower adjustment block 232. The lower adjustment block 232 (i.e., the lower roller body 222) loses the support of the limit block 233, and thus continues to slide downward under the action of the second elastic member 235, thereby increasing the gap between the lower roller body 222 and the upper roller body 221, thereby facilitating the passage of the starting end of the stainless steel coil 200. After changing the roll, the limit block 233 is driven in the reverse direction by the driving member 236, so that the limit block 233 moves in the direction close to the lower adjustment block 232, and the second inclined surface 2331 is able to force the lower adjustment block 232 (i.e., the lower roller body 222) to gradually slide upward through the first inclined surface 2321 until the limit block 233 is re-supported under the lower adjustment block 232, and the gap between the lower roller body 222 and the upper roller body 221 before the roll changing can be restored. In other words, the gap between the upper roller body 221 and the lower roller body 222 will not be changed after the roll changing operation, and there is no need to readjust it.

[0061] It should be noted that the present application does not limit the specific structure of the driving member 236, which can be driven by manual, electric, hydraulic, etc. The following only provides a preferred manual driving method for reference: Fig.11 , Fig.12 , Fig.16 as well as Fig.18 As shown, the driving member 236 includes a rotating shaft 2361, two connecting frames 2362 and two sliders 2363; each limit block 233 located on the front side of the fixed frame 21 is fixed to a connecting frame 2362, and each limit block 233 located on the rear side of the fixed frame 21 is fixed to another connecting frame 2362; the two sliders 2363 are respectively fixed to the two connecting frames 2362, and the two sliders 2363 are respectively threadedly connected to the rotating shaft 2361, and the thread direction between the two sliders 2363 and the rotating shaft 2361 is suitable for reverse setting, and at least one end of the rotating shaft 2361 is suitable for being provided with a handle 2364. That is to say, the rotating shaft 2361 can be rotated by turning the handle 2364, and under the action of the two sections of reverse threads, the two sliders 2363 can be forced to slide toward each other or slide away from each other; when the two sliders 2363 slide toward each other, the two connecting frames 2362 will also move toward each other, that is, the limit blocks 233 located on the front side of the fixing frame 21 and the limit blocks 233 located on the rear side of the fixing frame 21 will also move toward each other at the same time, thereby gradually separating from the corresponding lower adjustment blocks 232; similarly, when the two sliders 2363 slide away from each other, the limit blocks 233 located on the front side of the fixing frame 21 and the limit blocks 233 located on the rear side of the fixing frame 21 will also slide away from each other at the same time, thereby re-supporting the lower adjustment blocks 232. It should be understood that in order to prevent the slider 2363 from rotating with the rotating shaft 2361, the slider 2363, the connecting frame 2362 or the limit block 233 can be slidingly limited. The specific sliding limiting method is the existing technology and will not be described in detail here.

[0062] Reference Figure 20 to Figure 22In some embodiments of the present application, the leveling mechanism 5 includes a mounting frame 51, a plurality of first leveling components 52, and a plurality of second leveling components 53; the first leveling components 52 are arranged in sequence from left to right, and each first leveling component 52 includes an upper pressing roller 521 and a lower pressing roller 522, and both the upper pressing roller 521 and the lower pressing roller 522 are rotatably arranged on the mounting frame 51; the gaps between the upper pressing roller 521 and the lower pressing roller 522 on the first leveling components 52 from left to right decrease in sequence, the gap between the upper pressing roller 521 and the lower pressing roller 522 on the leftmost first leveling component 52 is less than the height of the wavy structure, and the gap between the upper pressing roller 521 and the lower pressing roller 522 on the rightmost first leveling component 52 is greater than the thickness of the stainless steel coil 200; the second leveling components 53 are arranged in sequence from left to right on the right side of the first leveling components 52, and each second leveling component 53 includes an upper leveling roller 531 and a lower leveling roller 532, and both the upper leveling roller 531 and the lower leveling roller 532 are rotatably arranged on the mounting frame 51, and the gap between the upper leveling roller 531 and the lower leveling roller 532 is greater than or equal to the gap between the upper pressing roller 521 and the lower pressing roller 522 on the rightmost first leveling component 52; a pressing ring 5311 protrudes radially in the middle of the upper leveling roller 531 (the pressing ring 5311 can also be arranged in the middle of the lower leveling roller 532), and the gap between the pressing ring 5311 and the lower leveling roller 532 is equal to the thickness of the stainless steel coil 200, the axial widths of the pressing rings 5311 on the second leveling components 53 from left to right increase in sequence, and the axial width of the pressing ring 5311 on the rightmost second leveling component 53 is greater than or equal to the width of the stainless steel coil 200. Among them, the method of driving the upper pressing roller 521, the lower pressing roller 522, the upper leveling roller 531, and the lower leveling roller 532 to rotate is the prior art, for example, the same as the method of driving the upper traction roller 15 to rotate, and will not be elaborated in detail here.

[0063] Specific working principle of the leveling mechanism 5: As Fig. 20 and Fig.21 shown, taking three first leveling components 52 as an example, since the gaps between the upper pressing roller 521 and the lower pressing roller 522 on the first leveling components 52 from left to right decrease in sequence (i.e., H1 > H2 > H3), and the gap between the upper pressing roller 521 and the lower pressing roller 522 on the leftmost first leveling component 52 is less than the height of the wavy structure (i.e., H1 < H); therefore, when the wavy structure moves from left to right (from left to right in Fig.21 and Fig. 22When passing through each first leveling component 52 from top to bottom in sequence, the height of the wavy structure gradually decreases, that is, the width of the wavy structure gradually increases, and the wavy structure gradually tends to be flat. Also, since the gap between the upper pressing roller 521 and the lower pressing roller 522 on the rightmost first leveling component 52 is greater than the thickness of the stainless steel coil 200 (i.e., H3 > D), that is to say, when the wavy structure passes between the upper pressing roller 521 and the lower pressing roller 522, the upper pressing roller 521 and the lower pressing roller 522 do not clamp the stainless steel coil 200, so that the stainless steel coil 200 itself can stretch along its width direction, and thus the thickness of the stainless steel coil 200 will not change. After being leveled by each first leveling component 52, the height of the wavy structure is smaller, which is convenient for further leveling operation by the second leveling component 53.

[0064] As Figure 20 to Figure 23 shown, since the gap between the pressing ring 5311 and the lower leveling roller 532 is equal to the thickness D of the stainless steel coil 200, the axial width of the pressing ring 5311 on each second leveling component 53 from left to right increases in sequence (L1 < L2), and the axial width of the pressing ring 5311 on the rightmost second leveling component 53 is greater than or equal to the width of the stainless steel coil 200 (usually the axial width of the pressing ring 5311 on the rightmost second leveling component 53 is equal to the axial width of the upper leveling roller 531, that is, it is equivalent that the entire upper leveling roller 531 is the pressing ring 5311); therefore, when the wavy structure after passing through the first leveling component 52 passes through each second leveling component 53 from left to right in sequence, the pressing ring 5311 on each second leveling component 53 will gradually press the wavy structure from the middle to both sides to be flat. Also, since the gap between the upper leveling roller 531 and the lower leveling roller 532 is greater than or equal to the gap between the upper pressing roller 521 and the lower pressing roller 522 on the rightmost first leveling component 52 (M ≥ H3), therefore, during the process that each pressing ring 5311 gradually presses the wavy structure to be flat, the wavy structure gradually stretches from the middle to both sides, so the thickness of the stainless steel coil 200 will not be changed. Of course, in order to further improve the leveling effect, the number of the rightmost second leveling components 53 (i.e., the pressing ring 5311 with the axial width equal to the axial width of the upper leveling roller 531) is at least two (as Fig. 20 shown).

[0065] Referring to Fig. 20 , in some embodiments of the present application, in order to facilitate the adjustment of the gap between the upper pressing roller 521 and the lower pressing roller 522 and the gap between the upper leveling roller 531 and the lower leveling roller 532, and at the same time, facilitate the coil changing operation, the leveling mechanism 5 further includes a second position adjusting component 54. The structure and working principle of the second position adjusting component 54 are the same as those of the first position adjusting component 23, and will not be described in detail here.

[0066] It should be noted that the heating mechanism 3 and the conveying mechanism 4 are prior art. For example, the heating mechanism 3 is a heating coil (such as Fig.19 As shown in FIG. 1 , the conveying mechanism 4 is a roller conveyor. In the case of heating by the heating coil, by bending the stainless steel coil 200 into a wavy structure, the width of the stainless steel coil 200 is reduced, and the size of the stainless steel coil 200 in the thickness direction is increased, so as to avoid the heating channel formed on the heating coil being too flat, thereby facilitating the improvement of the heating efficiency of the heating coil.

[0067] In addition, the stretching mechanism, the punching mechanism, the stamping mechanism and the bending mechanism themselves are all existing technologies, and their specific structures and working principles will not be described in detail here.

[0068] The present application also provides a method for processing an automobile decorative strip, comprising a stretching step, a bending step, an annealing step, a flattening step and a forming step.

[0069] Rolling step: The stainless steel raw material is subjected to at least one rolling process by the rolling mechanism to obtain a stainless steel coil 200 with a thickness of 0.3 mm to 0.6 mm.

[0070] Bending steps: The stainless steel coil 200 with a thickness of 0.3 mm to 0.6 mm is pulled through the bending mechanism 2 by the pulling mechanism 1. While keeping the thickness of the stainless steel coil 200 unchanged, the stainless steel coil 200 is bent along the width direction by the bending mechanism 2 to form a wavy structure.

[0071] Annealing step: The stainless steel coil 200 with a corrugated structure is input into the heating mechanism 3 for heating. The heated stainless steel coil 200 continues to be transported along the conveying mechanism 4 and gradually cooled on the conveying mechanism 4, thereby completing the annealing process.

[0072] Leveling step: The annealed stainless steel coil 200 is fed into the leveling mechanism 5 , and the stainless steel coil 200 is leveled along the width direction by the leveling mechanism 5 while keeping the thickness of the stainless steel coil 200 unchanged.

[0073] Forming steps: the flattened stainless steel coil 200 is input into the punching mechanism for punching, so as to obtain the decorative strip body 100 and the extension section extending along the side of the decorative strip body 100; then, a protrusion 102 is punched on the side wall of the decorative strip body 100 by the punching mechanism, and the extension section is bent by the bending mechanism to form the plug-in portion 101.

[0074] In summary, when the automobile decorative strip is processed by the processing method and processing equipment provided by the present application, before the annealing operation (i.e., heating), the stainless steel coil 200 is bent along the width (i.e., front and back) direction to form a wavy structure through the bending mechanism 2 without changing the thickness, thereby increasing the strength of the stainless steel coil 200, so that it will not bend and deform when passing through the heating mechanism 3 (i.e., during the annealing process), thereby ensuring the uniformity of the thickness of the stainless steel coil 200; after annealing, the wavy structure is re-flattened through the flattening mechanism 5 without changing the thickness, so that during punching and forming, no waste will be produced due to uneven thickness, and the yield rate of the automobile decorative strip is fully improved.

[0075] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
