Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a stainless steel wire stamping die. Background Technology

[0002] A punch, also called a punch bar, punch needle, or punch, is a metal part on a stamping die. It is usually installed on the upper die to perform continuous punching, stamping, and cutting operations, causing the processed material to separate or plastically deform, thereby obtaining the desired finished or semi-finished product.

[0003] When a punch is used for stamping, the material is deformed. Operations can be divided into punching, cutting, bending, and trimming. When bending to different sizes, the mold needs to be changed, which is not only costly but also time-consuming and inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a stainless steel wire stamping die to address the shortcomings of existing technologies.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A stainless steel wire stamping die includes an upper die assembly and a lower die assembly, with multiple punching mechanisms and bending mechanisms arranged along the length of the upper and lower die assemblies.

[0007] The punching mechanism includes a punching seat installed on the upper die assembly, a top punching die installed at the bottom of the punching seat, and a bottom punching die installed on the top of the lower die assembly, which is coaxially aligned with the top punching die.

[0008] The bending mechanism includes a top bending seat installed on the upper mold module, a top bending mold installed at the bottom of the top bending seat, and a bottom bending mold that cooperates with the top bending mold installed on the top of the lower mold module. The bottom bending mold includes a pair of spaced-apart bottom bending seats and a mold fixing seat for installing the bottom bending seats. The distance between the two bottom bending seats can be adjusted.

[0009] Furthermore: the upper mold module includes a top fixed seat, a top mounting seat and a top drive seat, with a gap between the top fixed seat and the top drive seat, wherein the top mounting seat is connected between the top fixed seat and the top drive seat, a top positioning plate is installed at the bottom of the top drive seat, the top positioning plate is formed with a top guide hole, and a top guide post passing through the top guide hole is installed on the top drive seat.

[0010] Furthermore: the lower mold module includes a bottom fixed seat, a bottom mounting seat and a bottom drive seat arranged sequentially from bottom to top. The bottom drive seat is formed with a bottom guide hole that is coaxially engaged with the top guide post. A bottom guide sleeve is installed in the bottom guide hole, and the top guide post and the bottom guide sleeve are slidably engaged.

[0011] Furthermore: the bottom of the top drive seat has a recessed top drive groove, and the top drive groove is fitted with a mold fixing plate. The punching seat and the top bending seat are both installed at the bottom of the mold fixing plate.

[0012] Furthermore: the top positioning plate has a top punching hole for the top punching die to pass through and a top bending hole for the top bending die to pass through.

[0013] Furthermore, a top compression spring is provided between the top drive seat and the top positioning plate to elastically move the top positioning plate away from the top drive seat.

[0014] Furthermore: a bottom mold plate is installed at the bottom of the bottom drive seat, and the bottom punching mold and the bottom bending mold are both installed on the top of the bottom mold plate. The bottom drive seat has a bottom bending hole for the bottom bending mold to pass through and a bottom punching hole for the bottom punching mold to pass through.

[0015] Furthermore: the bottom mold plate is formed with an adjustment groove along its length, and the mold fixing seat can be adjusted in position along the length of the adjustment groove.

[0016] Furthermore: One side of the lower mold module is provided with an inlet plate for material entry. The inlet plate is flush with the bottom drive seat, and upright guide plates are provided on both sides of the inlet plate.

[0017] Furthermore, on the other side of the lower mold module, there is a material feeding plate arranged opposite to the entry plate, which is inclined downwards to allow the material to slide and be fed.

[0018] The beneficial effects of this utility model are as follows: When the stainless steel raw material enters between the upper and lower die assemblies, it will be processed by multiple punching and bending mechanisms. When passing through the bending mechanism, the top bending die will contact the top of the raw material and then press the raw material down, achieving the bending effect in conjunction with the bottom bending seat. The distance between the two bottom bending seats can also be adjusted according to requirements. The adjusted bottom bending seats can change the length of the raw material after bending, eliminating the need for custom-made dies and saving costs. Furthermore, the entire stamping die does not need to be disassembled, saving a significant amount of time. Attached Figure Description

[0037] The present invention will now be described in detail with reference to the accompanying drawings.

[0038] like Figure 1-4 As shown, a stainless steel wire stamping die includes an upper die assembly 1 and a lower die assembly 2. The upper die assembly 1 can move up and down to approach or move away from the lower die assembly 2. Multiple punching mechanisms 3, bending mechanisms 4 and punching mechanisms are arranged in the length direction between the upper die assembly 1 and the lower die assembly 2.

[0039] The punching mechanism 3 includes a punching seat 31 installed on the upper die module 1, a top punching die 32 installed at the bottom of the punching seat 31, and a bottom punching die 33 coaxially aligned with the top punching die 32 installed at the top of the lower die module 2.

[0040] The bending mechanism 4 includes a top bending seat 41 installed on the upper mold module 1, a top bending mold 42 installed at the bottom of the top bending seat 41, and a bottom bending mold that cooperates with the top bending mold 42 installed on the top of the lower mold module 2. The bottom bending mold includes a pair of spaced bottom bending seats 43 and a mold fixing seat 44 for installing the bottom bending seats 43. The distance between the two bottom bending seats 43 can be adjusted.

[0041] Stainless steel raw material enters between upper die assembly 1 and lower die assembly 2, where it is processed by multiple punching mechanisms 3, bending mechanisms 4, and punching mechanisms. When passing through bending mechanism 4, the top bending die 42 contacts the top of the raw material, and then presses the raw material down, achieving the bending effect in conjunction with the bottom bending seat 43. The distance between the two bottom bending seats 43 can also be adjusted according to requirements, and the adjusted bottom bending seats 43 can change the length of the raw material after bending. There is no need to customize the die, which can save costs. Moreover, there is no need to disassemble the entire stamping die, which saves a lot of time.

[0042] Specifically, the upper mold module 1 includes a top fixed seat 11, a top mounting seat 12, and a top drive seat 13. A gap exists between the top fixed seat 11 and the top drive seat 13. The top mounting seat 12 connects the top fixed seat 11 and the top drive seat 13. A top positioning plate 14 is mounted on the bottom of the top drive seat 13, and the top positioning plate 14 has a top guide hole 16 formed therein. A top guide post 15 passing through the top guide hole 16 is mounted on the top drive seat 13. The lower mold module 2 includes a bottom fixed seat 21, a bottom mounting seat 22, and a bottom drive seat 23 arranged sequentially from bottom to top. The bottom drive seat 23 has a bottom guide hole 24 coaxially fitted with the top guide post 15. A bottom guide sleeve 20 is mounted in the bottom guide hole 24, and the top guide post 15 slides in conjunction with the bottom guide sleeve 20.

[0043] In this embodiment, the upper die module 1 moves up and down under the drive of the lifting cylinder. The top guide rod installed on the top drive seat 13 slides with the bottom guide sleeve 20 of the bottom drive seat 23, ensuring that the punching mechanism 3 between the upper die module 1 and the lower die module 2 is vertically aligned, the bending mechanism 4 between the upper die module 1 and the lower die module 2 is vertically aligned, and the punching mechanism between the upper die module 1 and the lower die module 2 is vertically aligned. This improves the stability and accuracy of the processing.

[0044] Furthermore, the bottom of the top drive seat 13 is recessed with a top drive groove 25, and a mold fixing plate 26 is installed in the top drive groove 25. The punching seat 31 and the top bending seat 41 are both installed at the bottom of the mold fixing plate 26. The top positioning plate 14 has a top punching hole 27 for the top punching die 32 to pass through and a top bending hole 28 for the top bending die 42 to pass through. When the raw material needs to be bent, the top punching die 32 installed in the mold fixing plate 26 can pass through the top bending hole 28 and protrude to the bottom, cooperating with the material attached to the lower mold assembly 2 to achieve stamping bending.

[0045] In addition, a top compression spring 29 is provided between the top drive seat 13 and the top positioning plate 14 to drive the top positioning plate 14 elastically away from the top drive seat 13. After the upper mold assembly 1 retracts, the elastic force of the top compression spring 29 will drive the top positioning plate 14 to press down, and the top punching die 32 will not be exposed downwards; during punching, the top positioning plate 14 presses down and first fits and positions itself against the top of the raw material, and then the upper mold assembly 1 continues to press down, and the top punching die 32 passes through the top punching hole 27 to punch and shape the raw material, preventing the raw material from shifting during punching.

[0046] A bottom mold plate 34 is mounted on the bottom of the bottom drive base 23. The bottom punching die 33 and the bottom bending die are both mounted on the top of the bottom mold plate 34. The bottom drive base 23 has a bottom bending hole 35 for the bottom bending die to pass through and a bottom punching hole 36 for the bottom punching die 33 to pass through. During stamping, the bottom bending die and the bottom punching die 33 located in the lower die assembly 2 support the raw material to prevent deformation of the raw material after stamping, thereby ensuring the quality of stamping.

[0047] Specifically, the top bending mold 42 has a top inclined surface 45 formed at the bottom, and the bottom bending seat 43 has a bottom inclined surface 46 formed at the top, which is parallel to the top inclined surface 45. During bending, the top inclined surface 45 and the bottom inclined surface 46 slide, so that the bent material abuts against the bottom inclined surface 46 to form a bend.

[0048] Furthermore, the bottom mold plate 34 has an adjusting groove 47 formed along its length, and the mold fixing seat 44 can be adjusted in position along the length of the adjusting groove 47. Through the sliding engagement between the mold fixing seat 44 and the adjusting groove 47, the position of the mold fixing seat 44 can be moved, thereby achieving position adjustment. It should be noted that the adjusting groove 47 has multiple connecting holes formed along its length, and the mold fixing seat 44 is provided with mounting holes that mate with the connecting holes. The mounting holes are connected to one of the connecting holes by bolts to install and fix the mold fixing seat 44.

[0049] Furthermore, an inlet plate 17 for material entry is provided on one side of the lower die module 2. The inlet plate 17 is flush with the bottom drive seat 23. Upright guide plates 18 are provided on both sides of the inlet plate 17. The raw material can enter between the upper die module 1 and the lower die module 2 through the inlet plate 17 and then be stamped. On the other side of the lower die module 2, a blanking plate 19 is provided opposite to the inlet plate 17. The blanking plate 19 is inclined downward to allow material to slide and be unloaded. After stamping, the product slides inclined along the blanking plate 19 to achieve unloading.

[0050] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0051] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
