Description

Technical Field

[0001] This utility model belongs to the field of steel sheet stamping die technology, and specifically relates to a steel sheet composite stamping die. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are made by applying pressure to the material using dies mounted on a press, causing it to separate or plastically deform, thereby obtaining the desired parts. The steel sheets are made of original imported stainless steel that has been heat-treated and precision-ground, and have the characteristics of high precision, strong tensile strength, good surface finish, toughness and not easy to break. Therefore, when steel sheets are formed by stamping steel plates, the scrap around the steel sheets is difficult to fall off under the pressure, which increases the workload for subsequent cutting.

[0003] Chinese patent CN202323546112.0 discloses a composite die for punching gaskets, including a base plate mounted on the worktable of a punch press, an upper die connected to the punch press slide, and a lower die mounted on the base plate. The upper die includes an outer punch, an inner punch, and an inner rubber pad. The top of the outer punch is fixedly connected to the punch press slide by bolts, and its bottom center is hollow. The inner punch is fixed inside the hollow position at the bottom of the outer punch. The inner rubber pad is sleeved on the outside of the inner punch and located inside the bottom of the outer punch. The lower die includes a lower die, a positioning rod, and an outer rubber pad. The lower die is fixed on the base plate by a pressure block. The positioning rod is installed on the lower die by an interference fit. The outer rubber pad is sleeved on the outside of the lower die and located on the pressure block.

[0004] In current stamping dies, the die is usually removed after extrusion molding for subsequent operations. However, since the stamped steel sheet is still on the steel plate, it needs to be cut to separate the steel sheet from the steel plate when it is removed. This causes inconvenience for subsequent cutting, does not reduce the workload of subsequent cutting, and easily wastes time and resources.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a steel sheet composite stamping die to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a composite steel sheet stamping die, comprising a fixed base, a worktable connected to the top of the fixed base, a driving assembly and a cutting assembly respectively arranged on the worktable, a fixed frame connected to the top of the fixed base, a third driving source connected to the top of the fixed frame, a support plate connected to the power output end of the third driving source, a reinforcing rod connected to the bottom end of the support plate, and an upper die connected to the bottom end of the reinforcing rod.

[0030] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0032] Please see Figures 1-6 As shown, this utility model is a composite steel sheet stamping die, including a fixed base 1. A worktable 4 is connected to the top of the fixed base 1. A driving assembly 2 and a cutting assembly 3 are respectively arranged on the worktable 4. A fixed frame 5 is connected to the top of the fixed base 1. A third driving source 6 is connected to the top of the fixed frame 5. A support plate 7 is connected to the power output end of the third driving source 6. A reinforcing rod 8 is connected to the bottom end of the support plate 7. An upper die 9 is connected to the bottom end of the reinforcing rod 8.

[0033] The bottom end of the support plate 7 is connected to four connecting rods 10, and a composite spring 12 is sleeved on the outer side of each of the four connecting rods 10. The bottom end of the four composite springs 12 is connected to a connecting plate 11. The inner side of the workbench 4 is connected to a reinforcing plate 16. The top end of the reinforcing plate 16 is connected to a fourth drive source 17. The power output end of the fourth drive source 17 is connected to a lower mold 18.

[0034] The surface of the drive assembly 2 is connected to the inner side of the worktable 4 to drive the drive assembly 2 to rotate.

[0035] The surface of the cutting component 3 is poweredly connected to the power output end of the driving component 2, so as to drive the cutting component 3 to rotate around the driving component 2 to cut the scraps of the steel sheet.

[0036] First, the steel sheet to be stamped is placed on the workbench 4, directly below the upper mold 9. Then, the support plate 7 and the reinforcing rod 8 are driven to move downwards by the third drive source 6. The upper mold 9 is driven to move downwards by the reinforcing rod 8, gradually squeezing the steel sheet until the upper mold 9 moves downwards and engages with the lower mold 18. At this time, the steel sheet is stamped. When the upper mold 9 moves downwards, the slot opened inside the bottom end of the connecting plate 11 will correspond to and fit with the stop rod 13. The composite spring 12 will contract when squeezed, which not only does not affect the downward movement of the connecting plate 11, but also plays a buffering role, avoiding the situation where the connecting plate 11 moves downwards and fits with the steel sheet, thus affecting the stamping. At the same time, the cutting component 3 is driven to revolve around the driving component 2 by the operation of the drive component 2, thereby cutting the corners of the formed steel sheet, which is convenient for reducing the workload of subsequent cutting steps. Then, the upper mold 9 is driven to move upwards by the third drive source 6, and the lower mold 18 is driven to move upwards by the fourth drive source 17, so that the finally formed steel sheet can be moved upwards and taken out.

[0037] The drive component 2 facilitates the driving of the cutting component 3 to revolve around the drive component 2, which facilitates the rotation of the cutting component 3 to cut the stamped steel plate, thereby removing most of the scrap material from the steel sheet. This reduces the workload for subsequent cutting steps and improves the practicality of use. The fourth drive source 17 facilitates the upward movement of the lower mold 18 to push out the cut steel sheet, making it easier to remove the steel sheet.

[0038] In one embodiment, the drive assembly 2 includes a first drive source 21 and four support blocks 24. The first drive source 21 is disposed inside the worktable 4, and the power output end of the first drive source 21 is poweredly connected to a drive gear 22. The four support blocks 24 are all disposed inside the worktable 4, and the top ends of the four support blocks 24 are slidably connected to a transmission gear 23, which meshes with the drive gear 22.

[0039] First, the steel plate to be stamped is placed on the workbench 4, directly below the upper die 9. Then, the support plate 7 and the reinforcing rod 8 are driven downward by the third drive source 6. The reinforcing rod 8 drives the upper die 9 downward, gradually compressing the steel plate until the upper die 9 engages with the lower die 18. At this point, the steel sheet is stamped. When the upper die 9 moves downward, the groove inside the bottom end of the connecting plate 11 will correspond and fit with the stop rod 13. The composite spring 12 will contract under compression, not only not affecting the downward movement of the connecting plate 11 but also acting as a buffer to prevent the connecting plate 11 from fitting against the steel plate and affecting the stamping. At the same time, the first drive source 21 is driven to operate, through the third drive source 6... A drive source 21 drives the drive gear 22 to rotate, which in turn drives the transmission gear 23 that meshes with it to rotate. The bottom end of the transmission gear 23 is slidably connected to four support blocks 24. Therefore, the transmission gear 23 is supported by the four support blocks 24, which improves the stability of the rotation of the transmission gear 23. At this time, the transmission gear 23 drives the cutting component 3 to revolve around the transmission gear 23 as the center, thereby cutting the edges and corners of the formed steel sheet, which reduces the workload for subsequent cutting steps. Then, the upper mold 9 is driven to move upward by the third drive source 6, and the lower mold 18 is driven to move upward by the fourth drive source 17, so that the finally formed steel sheet after cutting can be moved upward and taken out.

[0040] The first drive source 21 facilitates the rotation of the meshing drive gear 22 and transmission gear 23, which in turn drives the cutting assembly 3 to revolve around the transmission gear 23. This facilitates the rotation of the cutting assembly 3 to cut the stamped steel sheet, removing most of the scrap material. This reduces the workload for subsequent cutting steps and improves the practicality of the product. The fourth drive source 17 facilitates the upward movement of the lower mold 18 to push out the cut steel sheet, making it easier to remove the steel sheet.

[0041] In one embodiment, the cutting assembly 3 includes a fixing plate 31 and a cutting blade 33. The fixing plate 31 is disposed inside the transmission gear 23. A second drive source 32 is connected to the top of the fixing plate 31. The cutting blade 33 is disposed on the power output end of the second drive source 32, thereby facilitating the cutting of steel sheets by the cutting blade 33 and reducing the workload of subsequent cutting.

[0042] In one embodiment, the connecting plate 11 has four circular grooves on its surface, and the inner side of each groove is slidably connected to the surface of each connecting rod 10, thereby facilitating the sliding of the connecting plate 11 on the surface of the connecting rod 10 and improving the stability of the movement of the connecting rod 10.

[0043] In one embodiment, for the aforementioned composite springs 12, the top ends of all four composite springs 12 are connected to the bottom end of the support plate 7, thereby facilitating the provision of buffering force for the movement of the upper mold 9.

[0044] In one embodiment, for the workbench 4, the top of the workbench 4 is connected to two stop bars 13, and the bottom of the connecting plate 11 is provided with two slots, and the two stop bars 13 are respectively located directly below the two slots, so as to facilitate the limiting of the connecting plate 11 and prevent the connecting plate 11 from contacting the steel plate below and affecting the stamping of the steel plate.

[0045] In one embodiment, for the aforementioned fixed base 1, the top of the fixed base 1 is connected to two limiting plates 14, and a collection bucket 15 is slidably connected between the two limiting plates 14, thereby facilitating the placement of the collection bucket 15, which is beneficial for collecting the cut scraps, and also facilitates pushing the collection bucket 15 out for centralized processing of the scraps.

[0046] In summary, using the above-mentioned technical solution of this utility model, the steel plate to be stamped is first placed on the workbench 4, directly below the upper mold 9. Then, the support plate 7 and the reinforcing rod 8 are driven to move downward by the third drive source 6. The upper mold 9 is driven to move downward by the reinforcing rod 8, gradually squeezing the steel plate until the upper mold 9 moves downward and engages with the lower mold 18. At this time, the steel sheet is stamped. When the upper mold 9 moves downward, the groove opened inside the bottom end of the connecting plate 11 will correspond to and fit with the stop rod 13. The composite spring 12 will contract when squeezed, which not only does not affect the downward movement of the connecting plate 11, but also plays a buffering role, avoiding the situation where the connecting plate 11 moves downward and fits with the steel plate, thus affecting the stamping. At the same time, the first drive source 21 is driven to operate, which drives the drive gear 22 to rotate, and then the drive gear 22 drives the transmission gear 23 that meshes with it to rotate. The bottom end of the transmission gear 23 is slidably connected to four support blocks 24. Therefore, the support blocks 24 support the transmission gear 23, improving the stability of its rotation. At this time, the transmission gear 23 drives the fixed plate 31, the second drive source 32, and the cutting blade 33 to revolve around the transmission gear 23 as the center, and synchronously drives the second drive source 32 to operate. The second drive source 32 drives the cutting blade 33 to rotate, thereby cutting the edges and corners of the formed steel sheet, which reduces the workload for subsequent cutting steps. Then, the third drive source 6 drives the upper mold 9 to move upward, and the fourth drive source 17 drives the lower mold 18 to move upward, so that the finally formed steel sheet can be moved upward and taken out. The scraps after cutting will fall into the collection bucket 15 below. Simply slide the collection bucket 15 between the limiting plates 14 to collect and clean the scraps. The operation is simple.

[0047] Through the above technical solution, the first drive source 21 facilitates the rotation of the meshing drive gear 22 and transmission gear 23, which in turn drives the cutting blade 33 to revolve around the transmission gear 23. The second drive source 32 facilitates the rotation of the cutting blade 33 to cut the stamped steel sheet, thereby removing most of the scrap material from the steel sheet. This reduces the workload for subsequent cutting steps and improves the practicality of use. The fourth drive source 17 facilitates the upward movement of the lower mold 18 to push out the cut steel sheet, which is convenient for removing the steel sheet.
