Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a continuous stamping mold for automotive ABS cover. Background Art

[0002] Currently, the processing of automotive ABS covers all adopts stamping technology. The existing stamping process is basically carried out in stages according to the stamping process. First, the blanking process is to blank the sheet into a round blank as required. Then, the blanked round blank is stamped into shape under the stamping machine. Finally, the edge trimming process is to remove the excess sheet material around the outer perimeter of the stamped cover. In this process, the materials between each process must be manually transferred.

[0003] This stamping method, which completes one process in a single step, has low production efficiency and high labor costs. It is generally only suitable for small-batch processing. However, existing stamping processes obviously cannot meet the processing requirements for large-batch production. Utility Model Content

A matrix arrangement of push springs is provided between the upper die and the pressure plate.

[0006] To prevent the material strip from shifting during movement, conical positioning molds are installed at a distance from front to back on the bottom left end of the pressure plate.

[0007] To better facilitate the dropping of the trimmed cover into the storage bin, a pusher die head is fixed on the bottom surface of the upper die on the right side of the trimming die head to push the trimmed cover downward out of the lower die.

[0008] Preferably, the cross-section of the punching die is an X shape composed of two circular arcs, wherein the left circular arc of the punching die forms the right semicircular arc of the circular blank, and the right circular arc of the punching die forms the left semicircular arc of the circular blank.

[0009] Because effective support for the strip material is required during the stamping process, several pairs of support columns are provided at intervals on the lower die on the left side of the forming die head. The outer periphery of each support column has an annular groove, and the front and rear sides of the moving strip material are locked in the annular groove. Several pairs of clamping components are provided at intervals on the lower die on the right side of the forming die head, which cooperate to clamp the front and rear sides of the strip material. The clamping components include an L-shaped clamp fixed on the lower die. The inner side of the L-shaped clamp has a downward-facing stepped surface. A circular support column is provided on the lower die on the right side of the L-shaped clamp. The stepped surface is pressed against the upper plane of the front and rear sides of the strip material, and the circular support column is supported on the lower plane of the front and rear sides of the strip material.

[0010] Furthermore, a through hole is provided in the lower mold where the support column is located, the gap between the support columns is provided in the through hole, and a compression spring elastically supported on the bottom surface of the support column is provided in the through hole below the support column.

[0011] To facilitate the up-and-down movement of the upper mold, the lower mold has guide holes corresponding to the position of the lifting rod. The lower end of the lifting rod extends out of the bottom surface of the pressure plate and slides in cooperation with the guide holes. Guide sleeves are installed at the four corners of the upper mold, and guide posts that slide in cooperation with the guide sleeves are fixed at the four corners of the lower mold.

[0012] To facilitate waste collection, the lower mold template has a lower cutter on its right side, and the pressure plate has an upper cutter on its right side that works with the lower cutter to cut off the waste material after punching the cover.

[0013] The beneficial effects of this utility model are: by fixing a punching die head, a forming die head, a trimming die head and a pushing die head sequentially on the bottom surface of the upper die along the material strip moving direction, this utility model can realize continuous processing of the cover, improve processing efficiency, reduce production costs, and is suitable for the requirements of mass production.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] like Figures 1 to 6 The diagram shows a continuous stamping die for an ABS cover for automobiles, mounted on the worktable of a stamping machine. It includes an upper die 1 and a lower die 2. The upper die 1 is fixed to the punch of the stamping machine and moves up and down, while the lower die 2 is fixed to the worktable of the stamping machine. The lower die 2 works in conjunction with the upper die 1 to complete the stamping process of the cover. The material used for stamping the cover is steel strip. The strip to be stamped moves from the left side of the die to the right side, close to the upper surface of the lower die 2.

[0024] Along the direction of material strip movement, a punching die head 4, a forming die head 3, a trimming die head 5, and a pushing die head 10 are fixed sequentially on the bottom surface of the upper die 1. The punching die head 4 punches the moving material strip into a circular blank, and the front and rear ends of the circular blank are still attached to the material strip. The forming die head 3 punches the circular blank into a cover. The trimming die head 5 cuts off the excess edge material around the formed cover, so that the cover is separated from the material strip. The pushing die head 10 pushes the trimmed cover downward out of the lower die 2.

[0025] A forming die base 20 is fixed on the lower die 2 corresponding to the position of the forming die head 3, and a cutting die base 21 is fixed on the lower die 2 corresponding to the position of the cutting die head 5. A material dropping hole is opened on the lower die 2 corresponding to the position of the pushing die head 10. A storage bin corresponding to the position of the material dropping hole is set below the worktable of the stamping machine. The stamped cover falls into this storage bin through the material dropping hole.

[0026] The cross-section of the punching die 4 is an X shape composed of two circular arcs, the left circular arc of the punching die 4 forms the right semicircular arc of the circular blank after punching, and the right circular arc of the punching die 4 forms the left semicircular arc of the circular blank after punching. The lower die 2 has an arc-shaped punch that corresponds to the position of the punching die 4 and has the same shape.

[0027] A pressure plate 6 is provided between the upper mold 1 and the lower mold 2. Six hanging rods 7 are arranged in a matrix between the upper mold 1 and the pressure plate 6. The upper end of the hanging rod 7 is fixed to the upper mold 1. The pressure plate 6 and the hanging rod 7 are slidably engaged, and the lower end of the hanging rod 7 extends through the bottom surface of the pressure plate 7. A retaining ring is provided at the junction of the hanging rod 7 and the bottom surface of the pressure plate 7 to prevent the pressure plate 6 from sliding down. Through holes corresponding to the positions of the aforementioned mold heads are opened on the pressure plate 6.

The upper end of the push spring 8 is engaged in a countersunk hole opened in the upper mold 1, and the lower end of the push spring 8 is engaged in a countersunk hole opened on the pressure plate 7.

[0029] Conical positioning molds 9 are installed at a distance from each other on the left end of the pressure plate 6. When the material belt is conveyed, two small holes are first punched on the material belt at a distance from each other. In this way, when conveying, the two positioning molds 9 are inserted into the two small holes respectively, so that the length of the material belt can be controlled by positioning and feeding through the positioning molds 9.

[0030] The lower mold 2 is provided with three pairs of support columns 11 spaced apart from each other, with two columns arranged front and back in each pair. The support columns 11 are located on the left side of the forming die head 3. A through hole is opened in the lower mold 2 where the support columns 11 are located. The support columns 11 are spaced apart in the through hole. A compression spring 14 is provided in the through hole below the support column 11, which is elastically supported on the bottom surface of the support column 11. An annular groove 11-1 is opened on the outer periphery of each support column 11. The annular grooves 11-1 on each pair of support columns 11 are opposite to each other. The front and rear sides of the material strip are locked in the annular grooves 11-1 and limited in movement.

[0031] Three sets of clamping components are provided on the lower mold 2 located to the right of the forming die head 3, which are arranged in a lateral distance to clamp the front and rear sides of the material strip. Each set of clamping components includes two L-shaped clamps 12 and two round pillars 13 arranged in a lateral distance. The L-shaped clamps 12 are fixed on the lower mold 2, and the round pillars 13 are located to the right of the L-shaped clamps 12 and fixed on the lower mold 2. The inner side of the L-shaped clamps 12 has a downward step surface 12-1. The height of the step surface 12-1 is higher than the top surface of the round pillars 13. In this way, during the material strip conveying process, the step surface 12-1 is pressed against the upper plane of the front and rear sides of the material strip, and the round pillars 13 are supported on the lower plane of the front and rear sides of the material strip.

[0032] To ensure the accurate vertical movement of the upper mold 1 relative to the lower mold, the lower mold 2 is provided with guide holes 15 corresponding to the position of the lifting rod 7. The lower end of the lifting rod 7 extends out of the bottom surface of the pressure plate 6 and slides in cooperation with the guide holes 15. Guide sleeves 16 are installed at each of the four corners of the upper mold 1, and guide posts 17 that slide in cooperation with the guide sleeves 16 are fixed at each of the four corners of the lower mold 2.
