Description

Technical Field

[0001] This utility model relates to the field of hardware forming technology, specifically to a three-sided spring sheet forming structure. Background Technology

[0002] Stamping technology is a high-speed, automated metal forming process suitable for large-scale production. The stamping dies are manufactured with high precision, ensuring the dimensional and shape accuracy of the forming dies. It is currently widely used in parts processing in various fields.

[0003] For example, Chinese patent CN218517544U discloses a metal stamping forming die. In use, the upper die and the lower die are brought close to each other, and the metal parts are stamped and formed by the conformal structure inside the upper die and the lower die.

[0004] However, when processing hardware parts with multiple spring clips in the middle, the existing mold forming structure has difficulty in achieving one-time forming while ensuring smooth demolding after forming.

[0005] Based on this, the present invention designs a three-sided spring sheet forming structure to solve the above problems. Utility Model Content

A moving groove is provided in the middle of the upper mold base and the upper pad. The upper end of the force transmission ejector pin slides within the moving groove. The lower end of the force transmission ejector pin passes through the upper clamping plate and the stop plate and is connected to the three-sided force transmission module. The top of the force transmission ejector pin is fixedly connected to one end of the force transmission spring, and the top of the force transmission spring is fixedly connected to the upper mold base.

[0014] Furthermore, the three-sided force transmission module includes three-sided force transmission rods and inclined platform guide blocks.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0030] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-2 and Figure 5 A three-sided spring sheet forming structure includes an upper mold base 1, a synchronous stripping plate 2, a lower mold base 3, and a forming mechanism 4;

[0031] The upper mold base 1 is fixedly installed with an upper pad 11, an upper clamping plate 12, a stop plate 13 and a synchronous stripping plate 2 from top to bottom on the lower side; the lower mold base 3 is fixedly installed with a lower pad 31 and a lower template 32 from bottom to top on the upper side.

[0032] The upper mold base 1 and the synchronous stripping plate 2 are equipped with a forming mechanism 4 for forming hardware parts 5;

[0033] like Figure 2 and Figure 3 As shown, the forming mechanism 4 includes a main forming module 41, a three-sided force transmission structure 42, and a three-sided forming structure 43; the main forming module 41 for forming the main body of the hardware part 5 is installed on the lower template 32; the three-sided forming structure 43 for forming the three circumferentially distributed spring pieces 51 on the hardware part 5 is installed on the synchronous stripping plate 2; the three-sided force transmission structure 42 for synchronously driving the three-sided forming structure 43 to move is installed on the upper mold base 1.

[0034] In this embodiment, when the three-sided spring forming structure is working normally, the annular metal sheet for forming the hardware part 5 is placed between the lower template 32 and the synchronous stripping plate 2. The metal sheet for forming the hardware part 5 is located on the upper side of the main body forming module 41 on the lower template 32.

The main body of the metal sheet for forming the hardware part 5 is initially formed through the main body forming module 41. Then the synchronous stripping plate 2, the three-sided force transmission plate 42, and the three-sided spring forming structure 43 move vertically downward. The force structure 42 and the three-sided forming structure 43 continue to press down. Through the cooperation of the main forming module 41, the three-sided force transmission structure 42 and the three-sided forming structure 43, the three spring pieces 51 in the middle of the hardware part 5 are formed in a circular array. The upper mold base 1 drives the synchronous stripping plate 2 and the three-sided force transmission structure 42 and the three-sided forming structure 43 to move vertically upward through the upper pad plate 11, the upper clamping plate 12 and the stop plate 13, so that the three-sided force transmission structure 42 and the three-sided forming structure 43 are reset and the three-sided forming structure 43 is separated from the spring piece 51. Thus, while realizing the one-time forming of the hardware part 5 and the spring piece 51, it ensures smooth demolding after forming.

[0035] Example 2: In some embodiments, as a preferred embodiment of the present invention, such as... Figures 4-6 As shown, the main body forming module 41 includes a pad block 411 and a limiting block 412. The pad block 411 is fixedly installed on the upper side of the lower template 32. A forming groove 413 for forming the main body of the hardware 5 is opened on the upper side of the pad block 411. Three clearance grooves 414 are evenly spaced on the inner wall of the forming groove 413. The limiting block 412 is fixedly installed at the bottom of the forming groove 413.

[0036] The three-sided force transmission structure 42 includes a force transmission reset module and a three-sided force transmission module. The force transmission reset module is installed on the upper mold base 1, and the three-sided force transmission module is installed on the force transmission reset module.

[0037] The force transmission reset module includes a force transmission ejector pin 421 and a force transmission spring 422. A moving groove is provided in the middle of the upper mold base 1 and the upper pad 11. The upper end of the force transmission ejector pin 421 slides within the moving groove. The lower end of the force transmission ejector pin 421 passes through the upper clamping plate 12 and the stop plate 13 and is connected to the three-sided force transmission module. The top of the force transmission ejector pin 421 is fixedly connected to one end of the force transmission spring 422. The top of the force transmission spring 422 is fixedly connected to the upper mold base 1.

[0038] The three-sided force transmission module includes a three-sided force transmission rod 423 and a ramp guide block 424. The lower end of the force transmission pin 421 passes through the upper clamping plate 12 and the stop plate 13 and is fixedly connected to the upper end of the three-sided force transmission rod 423. Two sets of guide modules are arranged in a circular array on the three-sided force transmission rod 423. The guide module includes two ramp guide blocks 424. The ramp guide blocks 424 are fixedly installed on the three-sided force transmission rod 423.

[0039] The three-sided forming structure 43 includes a limiting movement module and a forming module. The limiting movement module is installed on the synchronous stripping plate 2, and the forming module is installed on the limiting movement module.

[0040] The limiting movement module includes a mounting base 431, a forming spring 432, and a forming slider 433. The mounting base 431 is fixedly mounted on the synchronous stripping plate 2. Three forming grooves 434 are evenly spaced and arranged in a circular array on the mounting base 431. The forming slider 433 is slidably mounted in the forming grooves 434. One end of the forming spring 432 is fixedly connected to the forming slider 433, and the other end of the forming spring 432 is fixedly connected to the synchronous stripping plate 2.

[0041] The molding module includes a spring forming protrusion 435 and a ramp guide groove 436. The spring forming protrusion 435 for forming the spring 51 is fixedly installed on the outer side of the bottom of the molding slider 433. Multiple ramp guide grooves 436 are provided on the inner side of the molding slider 433. The ramp guide grooves 436 slide in contact with the ramp guide block 424.

[0042] The stop plate 13 is also equipped with a stop spring and a stop block; a stop block for blocking the three-sided force transmission rod 423 is slidably installed on the lower side of the stop plate 13; one end of the stop spring is fixedly connected to the stop plate 13, and the other end of the stop spring is fixedly connected to the stop block.

[0043] In this embodiment, when the main body forming module 41, the three-sided force transmission structure 42, and the three-sided forming structure 43 are working normally, the metal sheet for forming the hardware part 5 is placed between the lower template 32 and the synchronous stripping plate 2. The metal sheet for forming the hardware part 5 is located on the upper side of the forming groove 413 on the lower template 32. The upper mold base 1 drives the synchronous stripping plate 2, the inclined guide block 424, and the spring forming protrusion 435 to move vertically downward through the upper pad 11, the upper clamping plate 12, and the stop plate 13, thereby pressing the metal sheet into the forming groove 413, and the main body of the metal sheet for forming the hardware part 5 is initially formed; until the three-sided force transmission rod 423 contacts the limiting block 412, the synchronous stripping plate 2 continues to move downward. The downward movement causes the inclined guide block 424 on the three-sided force transmission rod 423 to move relative to the inclined guide groove 436 on the inner side of the forming slider 433, compressing the force transmission spring 422. Through the cooperation of the inclined guide groove 436 and the inclined table surface on the inclined guide block 424, the forming slider 433 moves outward, and the spring forming protrusion 435 on the forming slider 433 presses the hardware 5 outward. The spring forming protrusion 435 cooperates with the forming groove 413 and the relief groove 414 to form the spring 51. The forming spring 432 is compressed. Then, the synchronous stripper plate 2 moves vertically upward, the force transmission spring 422 and the forming spring 432 reset, causing multiple forming sliders 433 to move inward, and then the hardware 5 is moved upward to achieve demolding.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
