Description

Technical Field

[0001] The utility model relates to the technical field of spring manufacturing, in particular to a molding die and molding equipment for a stretch-molded spring with an inner ring warping structure. Background Art

[0002] CN201910204229.X discloses a spring stretching process comprising the following steps: feeding; compacting; stretching a steel strip into shape; varying the diameter of the strip; and cutting. The stretching process stabilizes the dimensions of the formed steel strip spring, minimizing the error in the spring force, thereby expanding the application range of the spring. In particular, by varying the spring's forming dimensions, constant-force springs, variable-force springs, and special-force springs can be manufactured, broadening the application range of springs manufactured using the stretching process.

[0003] CN202410770587.8 discloses an automatic coil spring stretching machine, comprising a base and a steel strip pressing mechanism, a steering wheel, a first elastic trimming mechanism, a steel strip pulling mechanism, and a mold forming and cutting mechanism disposed on the base. The connecting line of the steel strip pressing mechanism, the steering wheel, the first elastic trimming mechanism, and the steel strip pulling mechanism forms a Z-shaped broken line structure. The first elastic trimming mechanism comprises a transverse cylinder, a first wheel frame, a first top wheel, a second top wheel, and a steering fixed shaft. The first wheel frame is connected to the transverse cylinder, and the first and second top wheels are disposed on the first wheel frame and are used to cooperate with the steering fixed shaft to apply stress to the steel strip. Compared with the prior art, the coil spring produced by the present invention has the advantage of stable elastic force.

[0004] The above technical solutions are all for forming coil springs, but they cannot meet the requirements under special working conditions. For example, when the inner ring of the spring needs to be raised and three-dimensionally shaped, the above-mentioned spring stretching forming process and the technical solutions of the automatic coil spring stretching forming machine cannot achieve this.

[0005] Regarding spring molding, existing spring forming processes typically manufacture the spring without pre-deforming it. Currently, there is no solution for forming the spring after stress has been applied. This limits the flexibility of spring manufacturing and the variety of functions that can be achieved, making it difficult to meet specific engineering needs or product design requirements. Utility Model Content

[0006] The purpose of the utility model is to provide a molding die and molding equipment for stretching and molding a spring with an inner ring warping structure, which can realize the molding of the spring inner ring warping structure.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions:

[0008] A molding die for a stretch-forming spring with an inner ring warping structure comprises a die body and a forming movable component, the die body being provided with a transverse channel for a steel strip to pass through and an action channel group for the forming movable component to move, the action channel group being vertically arranged and connected to the transverse channel, a molding structure being provided at a position corresponding to the action channel group on the transverse channel, the forming movable component comprising a warping structure cutting rod and a warping structure forming rod, the action channel group comprising a warping structure forming channel and a warping structure cutting channel, the warping structure forming rod being arranged in the warping structure forming channel, the warping structure cutting rod being arranged in the warping structure cutting channel, the die body comprising a warping die upper block, a warping die middle block and a warping die lower block, the warping die upper block, the warping die middle block and the warping die lower block being arranged in sequence from top to bottom, and the transverse channel being arranged between the warping die upper block and the warping die middle block.

[0009] In a preferred embodiment, the forming structure includes a tilting structure cutting hole and a tilting structure forming hole, the tilting structure cutting hole is connected to the tilting structure cutting channel, and the tilting structure forming hole is connected to the tilting structure forming channel.

[0010] In a preferred embodiment, the lower end surface of the tilting structure forming rod is provided with an inclined portion.

[0011] In a preferred embodiment, an upper surface edge of the middle block of the warping mold is provided with an arc surface corresponding to the position of the cutting hole of the warping structure, and the lower surface shape of the upper block of the warping mold is adapted to the arc surface.

[0012] In a preferred embodiment, a tilting forming mounting block is provided on the top of the tilting structure forming rod, and a tilting cutting mounting block is provided on the top of the tilting structure cutting rod.

[0013] In a preferred embodiment, the upper block of the warping mold, the middle block of the warping mold and the lower block of the warping mold are provided with through holes for installing the warping mold.

[0014] In a preferred embodiment, a mounting and fixing groove is provided on the side of the mold body.

[0015] A forming device comprises the forming die for stretching and forming a spring with an inner ring warping structure.

[0016] Compared with the prior art, the present invention provides a molding die for a spring with a raised inner ring structure, which has the following technical effects:

[0017] First, the steel strip used as the spring material carries inherent stress, which can significantly interfere with the spring's three-dimensional formation. However, the transverse channel constrains the steel strip, strictly limiting its range of motion as it passes through, ensuring it remains relatively straight. This constraint fundamentally prevents curling caused by the strip's stress, ensuring the correct spring formation.

[0018] Secondly, as the steel strip moves along the transverse channel, the warping structure forming rod gradually applies force to the steel strip according to a pre-set procedure or shape requirement. In this way, it can shape the steel strip into the required warping structure, thus ensuring the accurate formation of the warping structure of the spring inner ring.

[0019] Furthermore, once the steel strip has been shaped by the forming element, the tilting structure's cutting lever intervenes promptly, severing the strip with highly accurate cutting action. The accuracy of this action is crucial to the precision of spring production, ensuring that the formed steel strip meets the spring production requirements in terms of length and other aspects.

[0020] Finally, the block setting of the mold body brings great convenience. This block includes the upper block of the warping mold, the middle block of the warping mold and the lower block of the warping mold, which are arranged in sequence from top to bottom. This block setting is conducive to the production of the mold. During the production process, each module can be manufactured separately, which improves the efficiency and flexibility of production. At the same time, when a certain block is damaged, this block setting is conducive to repair and replacement. Compared with an integral mold, if a problem occurs in a certain part, it may need to be replaced as a whole or undergo complex repairs, while this block mold only needs to deal with the damaged module, reducing the cost and difficulty of repair.

DETAILED DESCRIPTION

[0026] The present invention will be described in further detail below with reference to the accompanying drawings.

[0027] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0028] Example 1:

[0029] like Figures 1 to 3 As shown, a molding die for a stretch-forming spring with an inner ring warping structure comprises a mold body 1 and a molding movable component, the mold body 1 is provided with a transverse channel 8 for the steel strip to pass through and an action channel group for the molding movable component to move, the action channel group is vertically arranged and connected to the transverse channel 8, a molding structure is provided on the transverse channel 8 at a position corresponding to the action channel group, the molding movable component comprises a warping structure cutting rod 13 and a warping structure molding rod 15, the action channel group comprises a warping structure molding channel 11 and a warping structure cutting channel 12, the warping structure molding rod 15 is arranged in the warping structure molding channel 11, the warping structure cutting rod 13 is arranged in the warping structure cutting channel 12, the mold body 1 comprises a warping mold upper block 2, a warping mold middle block 3 and a warping mold lower block 6, the warping mold upper block 2, the warping mold middle block 3 and the warping mold lower block 6 are arranged in sequence from top to bottom, and the transverse channel 8 is arranged between the warping mold upper block 2 and the warping mold middle block 3.

[0030] The molding die for stretching and forming a spring with an inner ring warping structure of this embodiment has the following technical effects:

[0031] First, the steel strip used as the spring material carries inherent stress, which can significantly interfere with the three-dimensional formation of the spring. However, transverse channel 8 constrains the steel strip, strictly limiting its range of motion as it passes through, ensuring that the strip remains relatively straight. This constraint fundamentally prevents curling caused by the stress in the strip, laying the foundation for the correct spring formation.

[0032] Secondly, as the steel strip moves along the transverse channel 8, the tilting structure forming rod 15 gradually applies force to the steel strip according to a pre-set procedure or shape requirement. In this way, it can shape the steel strip into the required tilting structure, thereby ensuring the accurate formation of the tilting structure of the spring inner ring.

[0033] Furthermore, once the steel strip has been shaped by the forming member, the tilting structure cutting rod 13 intervenes in a timely manner to cut the steel strip with a highly accurate cutting action. The accuracy of this action is of great significance to the precision of spring production, as it ensures that the length and other aspects of the formed steel strip meet the requirements of spring production.

[0034] Finally, the block arrangement of the mold body 1 brings great convenience. This block arrangement includes the upper block 2 of the warping mold, the middle block 3 of the warping mold, and the lower block 6 of the warping mold, which are arranged in sequence from top to bottom. This block arrangement is conducive to the production of the mold. During the production process, each module can be manufactured separately, which improves the efficiency and flexibility of production. At the same time, when a certain block is damaged, this block arrangement is conducive to repair and replacement. Compared with an integral mold, if a problem occurs in a certain part, it may need to be replaced as a whole or undergo complex repairs, while this block mold only needs to deal with the damaged module, reducing the cost and difficulty of repair.

[0035] Furthermore, the forming structure includes a tilting structure cutting hole 9 and a tilting structure forming hole 10, wherein the tilting structure cutting hole 9 is connected to the tilting structure cutting channel 12, and the tilting structure forming hole 10 is connected to the tilting structure forming channel 11. The tilting structure cutting hole 9 and the tilting structure forming hole 10 are connected to the tilting structure cutting channel 12 and the tilting structure forming channel 11, respectively. They provide the necessary space for the movement of the tilting structure forming rod 15 and the tilting structure cutting rod 13. This allows the tilting structure forming rod 15 and the tilting structure cutting rod 13 to fully perform their actions within the space constructed by their respective corresponding holes and channels, ensuring that the mold can smoothly perform the tilting structure forming and cutting operations on the steel strip.

[0036] Furthermore, the lower end surface of the tilting structure forming rod 15 is provided with an inclined portion 16. The setting of the inclined portion 16 can better form the tilting structure, ensure that the cavity structure is formed in accordance with the pre-designed concept during the spring manufacturing process, and help improve the accuracy and quality of spring forming.

[0037] Furthermore, the upper edge of the tilting mold middle block 3 is provided with a curved surface 4 at the location corresponding to the tilting structure cutting hole 9, and the lower surface of the tilting mold upper block 2 is shaped to conform to this curved surface 4. The curved surface 4 cooperates with the inclined portion 16 on the lower end of the tilting structure forming rod 15, and the two work together to accurately form the tilting structure that meets the design goals during the spring manufacturing process.

[0038] Furthermore, a tilting forming mounting block 5 is provided on the top of the tilting structure forming rod 15, and a tilting and cutting mounting block 14 is provided on the top of the tilting structure cutting rod 13. The tilting forming mounting block 5 and the tilting and cutting mounting block 14 can mount the tilting structure forming rod 15 and the tilting structure cutting rod 13 on the forming equipment. These two mounting blocks are connected to an actuating component such as a cylinder or an electric push rod, and the actuating component is mounted on the forming equipment. This structural design realizes the effective connection between the various components of the mold and the forming equipment, ensuring that the actuating component can accurately drive the forming rod and the cutting rod to work, thereby ensuring the smooth progress of the spring manufacturing process and improving overall work efficiency and stability.

[0039] Furthermore, the tilting mold upper block 2, the tilting mold middle block 3 and the tilting mold lower block 6 are provided with a tilting mold mounting through hole 7. The main function of the tilting mold mounting through hole 7 is to achieve assembly. When the mold is installed on the molding equipment, the rod of the molding equipment can pass through the through hole, thereby conveniently achieving the assembly and matching between the various mold blocks, effectively improving the efficiency of mold installation.

[0040] Furthermore, the side of the mold body 1 is provided with a mounting fixing groove 17. During the installation process, the moving fixing component of the molding equipment can be snapped into the mounting fixing groove 17, through which the mold body 1 is effectively fixed, ensuring the stability of the mold during operation.

The mold for forming a spring with an inner ring warping structure and a stretching structure is mounted on the molding device. To cooperate with the mold, the molding device is equipped with an electric push rod or a cylinder to drive the mold.

[0043] The above description of the embodiments is intended to facilitate understanding and use of the present invention by those skilled in the art. It is apparent that those skilled in the art can readily make various modifications to the embodiments and apply the general principles described herein to other embodiments without requiring creative effort. Therefore, the present invention is not limited to the above-described embodiments.
