Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a device for processing sheet metal parts using both progressive dies and engineering dies. Background Technology

[0002] Sheet metal processing is a crucial step in manufacturing. Traditional sheet metal processing typically employs single-operation dies or progressive dies. Single-operation dies have lower processing efficiency, while progressive dies, although more efficient, still have limitations in processing complex shapes or high-precision sheet metal parts. Currently, there is a need to process... Figure 1 The sheet metal part shown is complex. Existing processing technology completes the process through a single-process engineering mold. The material is fed manually, first cut, then placed in a DR mold to press out the shape, then placed in a trimming mold to cut off excess material, then placed in a shaping mold to press out the final shape, and finally placed in a punching mold to complete the punching. This processing method has low efficiency and poor precision.

[0003] Therefore, there is an urgent need for a processing device that can combine the advantages of progressive dies and engineering dies to improve the processing efficiency and quality of sheet metal parts. Summary of the Invention

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] like Figures 2 to 7 As shown, the present invention provides a stamping die for sheet metal parts, comprising a progressive die 1, a conveying mechanism (not shown), and an engineering die 3.

[0022] The connecting mold 1 includes an upper mold 11 and a lower mold 12. The upper mold 11, from top to bottom, includes an upper mounting plate 111, an upper pad 112, an upper mold base 113, an upper pad 114, an upper clamping plate 115, and an upper ejector plate 116. The lower mold 12, from bottom to top, includes a lower mounting plate 121, a lower pad 122, a lower mold base 123, a lower pad 124, and a lower clamping plate 125. The upper clamping plate 115, from left to right, includes a cutting station 4, a drawing station 5, a trimming station 6, a punching station 7, and a separation station 8. Each station is a symmetrically distributed dual-station structure. The upper ejector plate 116 is disposed on the upper clamping plate 115. The upper stripper plate 116 is provided with a floating clearance groove 1161, which is located at the left end of the cutting station 4; a cutting punch 41 is provided at the cutting station 4 located on the upper clamping plate 115, an upper template 51 is provided at the drawing station 5, a trimming punch 61 is provided at the trimming station 6, a punching punch 71 is provided at the punching station 7, and a separation punch 81 is provided at the separation station 8; the separation punch 81 has an "I" shaped structure, and the lower clamping plate 125 of the lower die 12 is provided with a cutting insert 42, a lower template 52, a trimming insert 62, a forming hole 72, and a separation insert 82, respectively. Each of these components corresponds to and cooperates with the cutting punch 41, upper template 51, trimming punch 61, punching punch 71, and separating punch 81, respectively. The lower clamping plate 125 is also equipped with two floating blocks 1251 and a lower floating plate 1252. The floating blocks 1251 are located at the front end of the cutting insert 42 and correspond to the floating relief groove 1161. The lower floating plate 1252 is set on the drawing station 5 and is located between the front and rear lower templates 52. By setting the floating blocks 1251 and the lower floating plate 1252, the strip material 100 can be supported, allowing the strip material to move more smoothly during the stamping process and avoiding friction or jamming. The feeding is not smooth due to the pause; located on the lower mold base 123 and at the front end of the cutting station 4, there are two corresponding guide plates 126. The opposite sides of the guide plates 126 are provided with guide grooves 1261 for guiding the material strip 100 into the connecting mold 1. Located on the lower mold base 123 and corresponding to the cutting station 4, trimming station 6, punching station 7 and separating station 8, there are cutting waste grooves 1231, trimming waste grooves 1232, punching waste grooves 1233 and separating unloading grooves 1234 respectively; the two sides of the lower mounting plate 121 are provided with unloading notches 1211 corresponding to the trimming waste grooves 1232.

[0023] The conveying mechanism (not shown) is used to convey the strip 100 on the continuous die 1.

[0024] The engineering mold 3 is a shaping mold, which includes a core 31 and a cavity 32, and is located at the end of the continuous mold 1.

[0025] Working principle: The strip 100 is introduced from the guide groove 1261 of the guide plate 126 and fed into the cutting station 4. The cutting punch 41 and the cutting insert 42 work together to cut the strip 100. The waste material falls from the cutting waste groove 1231. After cutting, the strip 100 is conveyed to the deep drawing station 5 through the conveying mechanism. The upper template 51 and the lower template 52 are used to draw and press the cut strip 100 into shape. Then the deep-drawn sheet metal part is conveyed to the trimming station 6 and trimmed by the trimming punch 61 to cut off the excess edge material. The edge waste falls out through the trimming waste groove 1232 and the blanking notch 1211. After trimming, the sheet metal part is conveyed to the punching station 7 and punched. The head 71 and forming hole 72 punch the trimmed sheet metal part. After punching, it is conveyed to the separation station 8, where the separation punch 81 and separation insert 82 separate the sheet metal part from the strip 100. Since the separation punch 81 has an "I" shaped structure, it can simultaneously separate the sheet metal part front to back and left to right, separating the two sheet metal parts from the strip. The two parts are then unloaded by the separation unloading groove 1234. Finally, the separated sheet metal part 100' is placed into the engineering mold 3 for shaping. The core 31 and cavity 32 perform the final shaping of the sheet metal part 100', completing the sheet metal part production. This process is simple and convenient, reduces manual feeding, saves labor costs, and can stamp and form two sheet metal parts at the same time, improving work efficiency.

[0026] This invention directly conveys the material strip into the continuous die via a conveying mechanism, completes the processing of sheet metal parts in one stamping, and finally completes the process with a shaping die. It is simple and convenient, eliminating the need for multiple transfers to a single-operation die. Furthermore, the dual-station structure allows for the simultaneous processing of two sheet metal parts, improving work efficiency.

[0027] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
