[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] like Figures 1-10 As shown, this utility model discloses a continuous processing mold for a fixed connection tensioning component for automobiles, comprising: The lower mold base 1 is a horizontal strip with recesses evenly distributed along its length on its top surface. The recesses include a first punch 111, a second punch 112, a shaping recess 113, a third punch 114, and a blanking hole 115, which are arranged sequentially, axially vertical, and are all through holes. The upper mold base 2 is in the same length direction as the lower mold base 1, and includes upper punches that are correspondingly arranged above the lower recess. The upper punches include a first punch 221, a second punch 222, a shaping punch 223, a third punch 224, and a trimming punch 225. The mold closing assembly 3 drives the upper mold base 2 and the lower mold base 1 to separate and close the mold, and is used to perform first punching, second punching, shaping, third punching and trimming on the strip 6 that passes between the upper mold base 2 and the lower mold base 1 and is in the same length direction as the two. The lifting component 4 is mounted on the lower mold base 1 and is used to lift the strip 6 between the upper mold base 2 and the lower mold base 1 to the bottom, which is higher than the top surface of the lower mold base 1, when the upper mold base 2 and the lower mold base 1 are separated.

[0020] This progressive die, also known as a continuous machining die, is used in the production of automotive fixed connection tension parts (in this invention, an elastic clamp) according to the following steps: S10. The mold closing assembly 3 separates the upper mold base 2 and the lower mold base 1, creating a certain gap between them. The material strip 6 passes through the gap between them, keeping the material strip 6 in the same length direction as the upper mold base 2 and the lower mold base 1. S20, the mold closing assembly 3 controls the upper mold base 2 to descend and close with the lower mold base 1, and punches the strip 6 once through the first punch 221 on the upper mold base 2; S30, the mold closing assembly 3 controls the upper mold base 2 to descend and the lower mold base 1 to separate the mold. The lifting assembly 4 lifts the strip 6 so that the bottom of the strip 6 is higher than the top surface of the lower mold base 1. The strip 6 moves a certain distance along the length of the lower mold base 1. The moving distance is the distribution interval of the recess. S40, the mold closing assembly 3 controls the upper mold base 2 to descend and close with the lower mold base 1, and performs secondary punching on the material strip 6 near the position of the first punching through the second punch 222 on the upper mold base 2; S50, Perform the operation of step S30; S60, the mold closing assembly 3 controls the upper mold base 2 to descend and close with the lower mold base 1, and the shaping protrusion 223 on the upper mold base 2 shapes the material strip 6 near the secondary punching position; S70, Perform the operation of step S30; S80, the mold closing assembly 3 controls the upper mold base 2 to descend and close with the lower mold base 1, and performs three punches on the material strip 6 at the position of the first punching hole through the third punch 224 on the upper mold base 2; S90, Perform the operation of step S30; S100, the mold closing assembly 3 controls the upper mold base 2 to descend and close with the lower mold base 1. The cutting protrusion 225 on the upper mold base 2 cuts the edge of the material strip 6 at the first punch position, so that the product formed on the material strip 6 is discharged downward through the material discharge hole 115 of the lower mold base 1.

[0021] As can be seen from the above operation steps, this continuous processing mold, through the cooperation of the lower mold base 1, the upper mold base 2, the mold closing assembly 3 and the lifting assembly 4, can sequentially perform one punching, two punching, shaping, three punching and trimming operations on the same part of the strip 6 without the need for frequent picking and putting of the strip 6, thereby greatly improving production efficiency.

[0022] A further improvement is that three first punches 111 are provided, and the lines connecting the centers of the top openings of the three first punches 111 form an isosceles right triangle. The right-angled side of the isosceles right triangle is parallel to the width direction of the lower die base 1. The lifting assembly 4 includes lifting units that are evenly distributed along the width direction of the lower die base 1 and whose distribution interval is the same as the distribution interval of the lower recess. The lifting unit includes two push rods 41 that are distributed along the width direction of the lower die base 1 and are axially vertical. The bottom end of each of the two push rods 41 is provided with a compression spring 42. The two push rods 41 correspond to the two ends of the hypotenuse of the right triangle.

[0023] Specifically, the length of the hypotenuse of the isosceles right triangle is the distribution interval of the lower notch of the lower die holder 1 and the distribution interval of the upper punch of the upper die holder 2. The upper die holder 2 is provided with three first punches 221 corresponding one-to-one with the three first punch holes 111. The first punch holes 111 are through holes. After the upper die holder 2 and the lower die holder 1 are closed, the three first punches 221 act on the strip 6, thereby forming on the strip 6 as shown in the figure. Figure 9 The three primary through holes 61 shown are respectively inserted into the three primary punch holes 111 by the three primary punches 221. After the primary punching, the waste material is discharged downward from the three primary punch holes 111. Among the three primary through holes 61, one is the center hole 611 and the other two are positioning holes 612. The center hole 611 is centered on the material strip 6, and the two positioning holes 612 are adjacent to the two sides of the material strip 6 respectively. After the upper mold base 2 and the lower mold base 1 are separated, the bottom end of the compression spring 42 acts on the ejector rod 41, causing the ejector rod 41 to move upward. The ejector rod 41 supports the material strip 6. The two ejector rods 41 are adjacent to the two sides of the material strip 6 respectively and are at the same horizontal distance from the two sides of the material strip 6 to achieve stable support for the material strip 6.

[0024] A further improvement is that the ejector pin 41 is an ejector tube, and the first punch 221 includes three punches that correspond to the three first punch holes 111 and extend in the vertical direction. The upper mold base 2 also includes a positioning rod 212 that slides in the vertical direction and is coaxial with the ejector pin 41. The outer diameter of the positioning rod 212 is consistent with the inner diameter of the ejector tube and the inner diameter of the first punch hole 111. When the mold is closed, the punches seal through the strip 6 and insert into the ejector tube to position the strip 6 in the horizontal direction.

[0025] With the above structure, after three punches form three primary through holes 61 on the strip 6, the strip 6 is lifted by the lifting assembly 4 and the hypotenuse of the isosceles right triangle is moved. When the upper mold base 2 descends and closes with the lower mold base 1 again, the positioning rod 212 of the upper mold base 2 can seal through the two positioning holes 612 and seal the insertion into the inner side of the ejector rod 41, thereby achieving horizontal positioning of the strip 6 and preventing the strip 6 from shifting. In this way, it is ensured that the center position of the subsequent secondary punching, shaping, tertiary punching and trimming corresponds to the axis of the center hole 611 formed during the primary punching, ensuring the subsequent processing accuracy. In order to facilitate the precise insertion of the positioning rod 212 through the positioning hole 612 into the inner side of the ejector rod 41, the bottom end of the positioning rod 212 is chamfered in this utility model, thereby reducing the bottom size of the positioning rod 212 and facilitating the sealing penetration of the positioning hole 612 of the strip 6 from top to bottom.

[0026] A further improvement is that the upper mold base 2 includes an upper mold cylinder 21 and a lifting plate 22 that are slidably connected relative to each other in the vertical direction. The first punch 221, the second punch 222, the shaping protrusion 223, the third punch 224 and the trimming protrusion 225 are all fixedly connected to the lifting plate 22. The upper mold cylinder 21 is sealed and sleeved outside the first punch 221, the second punch 222, the shaping protrusion 223, the third punch 224 and the trimming protrusion 225. The positioning rod 212 is connected to the upper mold cylinder 21.

[0027] With the above design, during mold closing, the upper mold cylinder 21 is first lowered so that the positioning rod 212 of the upper mold cylinder 21 can be inserted into the positioning holes 612 of the strip 6 to horizontally position the strip 6. At the same time, the upper mold cylinder 21 can apply pressure to the strip 6, which is transmitted to the ejector rod 41 supported by the compression spring 42, causing the ejector rod 41 to lower. Finally, the bottom surface of the strip 6 is brought into contact with the top surface of the lower mold base 1, and the lifting plate 22 is lowered, driving the first punch 221, the second punch 222, the forming protrusion 223, the third punch 224, and the trimming protrusion. 225 descends to achieve primary punching, secondary punching, shaping, tertiary punching, and edge trimming at different positions of the strip 6. During mold separation, the lifting plate 22 first drives the first punch 221, the second punch 222, the shaping protrusion 223, the third punch 224, and the edge trimming protrusion 225 to the highest position. Then, the upper mold cylinder 21 slowly rises, so that the lifting component 4 slowly lifts the strip 6, avoiding the upper mold cylinder 21 rising too fast, which would cause the ejector rod 41 to rise too fast, causing the strip 6 to bounce and resulting in a shift in the position of subsequent processing.

[0028] A further improvement is that the upper mold cylinder 21 is provided with an upper sliding hole 211 that extends vertically and corresponds to and seals with the positioning rod 212. The bottom end of the positioning rod 212 protrudes from the bottom surface of the upper mold cylinder 21. The upper sliding hole 211 is a stepped hole. The inner diameter of the top opening of the upper sliding hole 211 is larger than the inner diameter of the bottom opening. A counterweight ring 214 is fixed to the top of the positioning rod 212. The outer diameter of the counterweight ring 214 is consistent with the inner diameter of the top opening of the stepped hole and the two are coaxial.

[0029] With the above structure, in the initial stage of operation, when the material strip 6 corresponding to the upper sliding hole 211 has not yet formed a positioning hole 612, during mold closing, the positioning rod 212 can move vertically relative to the upper mold base 2 through the upper sliding hole 211. The counterweight ring 214 makes the positioning rod 212 maintain the tendency to move downward, so that after mold separation, the positioning rod 212 can descend until the counterweight ring 214 enters the upper part of the stepped hole. Since the outer diameter of the counterweight ring 214 is larger than the inner diameter of the hole at the bottom of the stepped hole, the positioning rod 212 can no longer move downward, thereby achieving the function of limiting the positioning rod 212.

[0030] A further improvement is that a magnetic ring 213 is fixed inside the upper sliding hole 211, and the counterweight ring 214 is magnetically attracted to the magnetic ring 213.

[0031] Specifically, the counterweight ring 214 is made of nickel-iron alloy. On the one hand, this ensures that it has sufficient weight, and on the other hand, it ensures that there is a strong attraction between it and the magnetic ring 213. This ensures that the positioning rod 212 can overcome the friction between itself and the upper sliding hole 211, so that the positioning rod 212 descends to the bottom of the counterweight ring 214 and comes into contact with the top of the magnetic ring 213.

[0032] A further improvement is that the mold clamping assembly 3 includes a first lifting unit 31 and a second lifting unit 32, the output ends of the first lifting unit 31 and the second lifting unit 32 being connected to the upper mold cylinder 21 and the lifting plate 22, respectively.

[0033] With the above structure, the independent lifting movements between the upper mold cylinder 21 and the lifting plate 22 can be easily controlled by the first lifting unit 31 and the second lifting unit 32, ensuring orderly mold closing and mold opening operations between the upper mold base 2 and the lower mold base 1.

[0034] After multiple consecutive processing steps, the material strip 6 changed from its original long strip shape to... Figure 8 The structure shown is, in particular, described below: After one punching, three primary through holes 61 are formed on the strip 6. The three primary through holes 61 are a central hole 611 and two positioning holes 612. As mentioned above, the line connecting the centers of the holes on the same surface of the three primary through holes 61 forms an isosceles right triangle, and the hypotenuse of the isosceles right triangle is parallel to the width of the strip 6. Finally, positioning holes 612 are evenly distributed on both sides of the strip 6, and central holes 611 are evenly distributed at the center of the strip 6. The distance between the above distribution intervals is the length of the hypotenuse of the isosceles right triangle.

[0035] This utility model has three second punches 112 and three corresponding second punches 222. That is, the mold of this utility model performs three repeated secondary punches on the strip 6. After the above-mentioned secondary punching, as Figure 9 As shown, three secondary irregular through holes 62 are formed on the material strip 6. A ring 63 is arranged between the three secondary irregular through holes 62. The inner hole of the ring 63 is the central hole 611. Side arms 64 integrally connected to the material strip 6 are distributed in a ring array on the outer circumferential edge of the ring 63. The side arm 64 includes an inner arm 641, an outer arm 642 and a connecting strip 643 integrally connected from the inside to the outside. The inner arm 641 and the outer arm 642 both extend radially along the ring 63. The width of the inner arm 641 is smaller than the width of the outer arm 642, and the length of the inner arm 641 is greater than the length of the outer arm 642. The connecting strip 643 is a slender zigzag shape.

[0036] The present invention has five shaping notches 113 and five shaping protrusions 223, which correspond one-to-one. That is, the mold of the present invention shapes the strip 6 five times in total. After shaping, a shaping recess 631 is formed at the first punching position of the strip 6. The depth of the shaping recess 631 gradually increases. Finally, the ring 63 is shaped to the bottom of the strip 6 and forms a barrel-shaped structure with an open top. The three inner arms 641 are respectively located on the same cylindrical surface of the barrel-shaped structure. The outer arm 642 is formed at the end of the inner arm 641 away from the ring 63. The connecting strip 643 is deformed and shortened in length.

[0037] The third punch 224 is used to perform a third punching, thereby forming a third through hole 65 on the strip 6, the third through hole 65 coaxially covering the center hole 611.

[0038] The cutting protrusion 225 is used to cut the ring 63, inner arm 641 and outer arm 642 from the connecting belt 643 to form the product, so that the product falls from the discharge hole 115.

[0039] More specifically, the lower mold base 1 includes a horizontal elongated lower module 11. A first punch 111, a second punch 112, a shaping notch 113, a third punch 114, and a blanking hole 115 are all provided on the lower module 11. A convex frame 12 is fixed to the bottom circumferential outer edge of the lower module 11. A support leg 13 is fixed to the bottom end of the convex frame 12. A base 7 is fixed to the bottom end of the support leg 13. The lower module 11 is also provided with a sliding hole 116 through which the ejector rod 41 passes vertically.

[0040] The base 7 is also provided with a waste trough 71 and a finished product trough 72, both with their openings facing upwards and inclined downwards. The higher ends of the two are adjacent to each other, and the lower ends are opposite to each other. The first punch 111, the second punch 112 and the third punch 114 are all located directly above the waste trough 71 to facilitate the discharge of waste formed after punching. The discharge hole 115 is located directly above the finished product trough 72 to facilitate the discharge of the processed product.

[0041] Both sides of the upper mold cylinder 21 are integrally connected with connecting seats 215. The mold closing assembly 3 also includes an inverted U-shaped bracket 33. The two ends of the bracket 33 are fixed above the base 7. The first lifting unit 31 is a first lifting cylinder. Its cylinder is fixed on the bracket 33, the piston rod is vertically downward, and the bottom end is fixedly connected to the connecting seat 215. The second lifting unit 32 is a second lifting cylinder. Its cylinder is fixed on the bracket 33, the piston rod is vertically downward, and the bottom end is fixedly connected to the lifting plate 22.

[0042] The lifting assembly 4 also includes an upper limit tube 43 and a lower limit tube 44, which are fixed below the lower module 11 and above the base 7, respectively. The two ends of the compression spring 42 are respectively located inside the upper limit tube 43 and the lower limit tube 44 to limit the range of motion of the two ends of the compression spring 42.

[0043] A further improvement is that it also includes a limiting component 5, which is located on both sides of the upper mold base 2 to limit the material strip 6 from shifting along the width direction of the upper mold base 2.

[0044] Specifically, the limiting component 5 includes a fixed shaft 51 fixedly connected to the upper mold base 2 and extending vertically, and a limiting tube 52 coaxially sleeved outside the fixed shaft 51 and rotating around its own axis. The limiting tube 52 is in contact with the side wall of the strip 6. The fixed shaft 51 is fixed vertically upward above the base 7. The inner diameter of the limiting tube 52 is the same as the outer diameter of the fixed shaft 51, thus facilitating the sliding of the limiting tube 52 along the fixed shaft 51 and allowing it to rotate around the axis of the fixed shaft 51, facilitating the positioning of the strip 6 and preventing positional displacement of the strip 6 in the width direction of the lower mold base 1.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
