Description

Technical Field

[0001] This utility model relates to the field of metal stamping die technology, and in particular to a multi-station die blanking structure. Background Technology

[0002] In the field of metal stamping, progressive dies are widely used due to their high efficiency, high precision, and ease of automation. Traditional single-station dies require multiple sets of dies and multiple presses to produce a single part, resulting in low production efficiency, large footprint, and problems with semi-finished product turnover and accumulated positioning errors. Progressive dies, by setting up multiple stations within a single die to sequentially complete various processes such as punching, bending, and drawing, significantly improve production efficiency.

[0003] However, in the practical application of progressive dies, problems such as complex structure and large amount of waste still exist. After the die performs stamping, blanking or forming, the edges of the workpiece usually have excess waste or burrs remaining. In order to ensure forming accuracy, progressive dies need to maintain a certain distance between adjacent stations, which often leads to waste retention, thus affecting the accuracy of progressive die closing and the forming effect. Utility Model Content

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figures 1 to 6 The multi-station die blanking structure of this utility model is illustrated in the following embodiments: A multi-station die blanking structure includes an upper die holder 100 and a lower die holder 200. The upper die holder 100 is located above the lower die holder 200, and a floating upper die 110 is provided on the lower side of the upper die holder 100. A fixed lower die 210 is provided on the upper side of the lower die holder 200 and is vertically aligned with the floating upper die 110.

[0023] The floating upper mold 110 has an upper forming part 111 on its lower side, and the fixed lower mold 210 has a plurality of lower forming parts 211 on its upper side that correspond one-to-one with the upper forming part 111.

[0024] The upper mold base 100 and the lower mold base 200 are configured to be able to close or separate from each other in the vertical direction to perform molding processing on the material.

[0025] The lower forming part 211 is provided with a plurality of forming holes 212, and the upper forming part 111 is provided with forming blocks 121 corresponding to the forming holes 212 one by one. The lower forming part 211 is provided with a material discharge channel 220 on its lower side, and the plurality of forming holes 212 are all connected to the material discharge channel 220.

[0026] In practical use, the upper mold base 100 and the lower mold base 200 either close towards each other or separate away from each other. When the upper mold base 100 and the lower mold base 200 close towards each other, the floating upper mold 110 and the fixed lower mold 210 abut against each other. The upper forming part 111 and the lower forming part 211 form the material between them. At the same time, the forming block 121 of the upper forming part 111 and the forming hole 212 of the lower forming part 211 shear the material. The sheared material can fall into the material discharge channel 220 along the forming hole 212, avoiding accumulation or affecting mold closing and ensuring molding quality.

[0027] In this embodiment, the floating upper mold 110 is adjustablely disposed on the upper mold base 100 in the vertical direction, and the forming block 121 is movably connected to the upper forming part 111. During the mold closing process, the upper forming part 111 and the lower forming part 211 abut against each other to form the material, and then the relative movement between the forming block 121 and the floating upper mold 110, in conjunction with the forming hole 212, achieves shearing and blanking processing.

[0028] Specifically, in this embodiment, the upper mold base 100 is provided with a shearing mold 120. The shearing mold 120 is adjustablely mounted on the upper mold base 100 along a first direction. The first direction is inclined to the vertical direction, and the forming block 121 is disposed on the shearing mold 120 and slides along a second direction with the floating upper mold 110.

[0029] In this embodiment, both the first direction and the second direction are inclined relative to the vertical direction. The floating upper mold 110 is provided with a groove extending along the second direction, and the forming block 121 slides through the groove. When the floating upper mold 110 moves vertically relative to the upper mold base 100, the shearing mold 120 moves relative to the upper mold base 100 along the first direction, thereby causing the shearing mold 120 to move relative to the floating upper mold 110 along the second direction. The end of the forming block 121 protrudes from the upper forming part 111 and passes through the forming hole 212 to achieve shearing and blanking processing of the material.

[0030] The shearing die 120 is elastically slidably connected to the upper die base 100 along the first direction, so that the shearing die 120 tends to move away from the floating upper die 110 along the first direction. Specifically, the upper die base 100 is provided with a nitrogen spring arranged along the first direction. The two ends of the nitrogen spring abut against the upper die base 100 and the shearing die 120 respectively, so that the shearing die 120 abuts against the floating upper die 110 along the first direction under the action of elastic force.

[0031] When the shearing die 120 is elastically pressed against the floating upper die 110 along the first direction and moves away from the floating upper die 110, the end of the shearing block is flush with the upper forming part 111.

[0032] In this embodiment, the shearing die 120 is further provided with a shearing portion 122 extending along the edge of the upper forming portion 111, and the shearing portion 122 and the upper forming portion 111 slide against each other along the second direction. When the shearing die 120 elastically presses against the floating upper die 110 along the first direction and moves away from the floating upper die 110, the shearing portion 122 is flush with the edge of the upper forming portion 111. When the shearing die 120 moves relative to the floating upper die 110 along the second direction, the shearing portion 122 and the shearing block extend synchronously relative to the upper forming portion 111 along the second direction, realizing the shearing and blanking at the corresponding position of the shearing block and the edge trimming of the formed product.

[0033] Correspondingly, at least a portion of the upper end of the material discharge channel 220 is vertically aligned with the shearing section 122. The shearing section 122 precisely trims the edges of the product, allowing edge waste to fall into the material discharge channel 220, preventing accumulation.

[0034] Furthermore, the shearing die 120 is provided with a first driving part 123, and the fixed lower die 210 is provided with a second driving part 213. Both the first driving part 123 and the second driving part 213 have mutually parallel driving planes, and these driving planes are aligned vertically. The first driving part 123 and the second driving part 213 are inclined relative to the first direction and the vertical direction.

[0035] In this embodiment, the floating upper mold 110 achieves this by having the first driving part 123 and the second driving part 213 approach each other during the mold closing process of the upper mold base 100 and the lower mold base 200. When the upper forming part 111 and the lower forming part 211 clamp and form the material, the first driving part 123 and the second driving part 213 abut against each other. After this, the upper mold base 100 and the lower mold base 200 continue to close towards each other, the floating upper mold 110 moves upward, and the shearing mold 120 moves relative to the upper mold base 100 towards the floating upper mold 110 in a first direction under the interaction of the first driving part 123 and the second driving part 213, so that the shearing mold 120 moves relative to the floating upper mold 110 in a second direction, thereby allowing the shearing part 122 and the shearing block to extend relative to the upper forming part 111 in a second direction, achieving edge trimming and blanking.

[0036] Referring to the accompanying drawings, in this embodiment, a plurality of first driving units 123 and second driving units 213 are arranged in a one-to-one correspondence. Each first driving unit 123 may have one or more driving planes, and the shape of the second driving unit 213 matches that of the first driving unit 123.

[0037] In this embodiment, both the upper mold base 100 and the lower mold base 200 are rectangular plates. Both the upper mold base 100 and the lower mold base 200 are rectangular in shape when projected vertically.

[0038] To ensure the mold closing accuracy of the upper mold base 100 and the lower mold base 200, the upper mold base 100 and the lower mold base 200 are respectively provided with vertically aligned positioning guide posts 130 and corresponding positioning guide sleeves 230, which are respectively located at the four corners of the upper mold base 100 and the lower mold base 200.

[0039] In this embodiment, the upper mold base 100 has four positioning guide posts 130 extending in the vertical direction at the four corners of its lower side, and the lower mold base 200 has four positioning guide sleeves 230 at the four corners of its upper side. The positioning guide sleeves 230 and the positioning guide posts 130 are coaxially arranged in a one-to-one correspondence.

[0040] In a further embodiment, the floating upper mold 110 and the fixed lower mold 210 are each provided with multiple pairs of vertically aligned positioning cones 214 and positioning conical grooves 112. The relative positioning accuracy of the floating upper mold 110 and the fixed lower mold 210 is improved by the matching conical surfaces between the positioning cones and positioning conical grooves 112.

[0041] In this embodiment, the material discharge channel 220 is inclined. The upper end of the material discharge channel 220 has a discharge port communicating with the forming hole 212, and the lower end of the material discharge channel 220 has a discharge port communicating with the side of the lower mold base 200. Sheared waste material falls from between the upper forming part 111 and the lower forming part 211 to the upper end of the material discharge channel 220, and slides down the material discharge channel 220 to the discharge port under its own weight, thus achieving waste material discharge.

[0042] The number of the material discharge channels 220 is multiple, and the discharge ports of the multiple material discharge channels 220 are respectively located on both sides of the opposite end of the lower mold base 200. The positions of the multiple material discharge channels 220 can be set according to the waste shearing position of the molded product, and this application does not impose specific limitations.

[0043] The lower mold base 200 is provided with a material discharge groove to form the material discharge channel 220. A slide rail sheet is embedded in the material discharge groove, forming the bottom end face of the material discharge channel 220. The slide rail sheet prevents scrap from scratching the lower mold base 200. Simultaneously, it improves the smoothness of the material discharge channel 220, reduces the processing requirements of the lower mold base 200, and decreases the friction experienced by the scrap within the material discharge channel 220, allowing it to be discharged more smoothly.
