Description
Technical Field
[0001] The utility model relates to the technical field of aluminum cover processing, in particular to a stamping progressive die for a shallow-drawn aluminum cover. Background Art
[0002] Mold processing refers to the processing of forming and blanking tools, and also includes shearing dies and die-cutting dies. Usually, the mold consists of two parts: the upper mold and the lower mold. The steel plate is placed between the upper and lower molds, and the material is formed under the action of the press. When the press is opened, the workpiece determined by the mold shape will be obtained or the corresponding waste will be removed. Workpieces as small as electronic connectors and as large as car dashboards can be formed by molds. Progressive die refers to a set of molds that can automatically move the workpiece from one station to another and obtain the molded part at the last station. When processing aluminum covers, progressive dies are needed.
[0003] When processing the existing aluminum cover, the aluminum sheet is usually stretched, stamped and cut through a progressive die to form the aluminum cover. During the processing, a large amount of metal debris is generated, but the existing progressive die cannot effectively clean the debris, which affects the accuracy of stamping, thereby increasing the yield rate of defective products. At the same time, the metal debris remains for a long time, which easily damages the service life of the mold. Utility Model Content

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example
[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a shallow-drawn aluminum cover stamping progressive die, comprising a lower die base 1, a fixing frame 2 is fixedly installed on one side of the lower die base 1 by two mounting bolts 8, a chip removal bin 3 is arranged on one side of the fixing frame 2, a dustproof net 4 is arranged on one side of the chip removal bin 3, a fixing plate 5 is arranged at the bottom of the dustproof net 4, a plurality of axial flow fans 6 are evenly distributed on the top of the fixing plate 5, and a chip removal bucket 7 is arranged at the bottom of the chip removal bin 3.
[0024] In this embodiment, the axial flow fan 6 generates suction during operation, and the metal debris generated by the processing on the lower mold base 1 is sucked into the chip removal bin 3. The dustproof net 4 can prevent the metal debris from escaping from the chip removal bin 3. When the axial flow fan 6 stops or too much metal debris accumulates in the chip removal bin 3, the influence of the suction on the metal debris is reduced, and the metal debris gradually falls and is discharged from the chip removal bucket 7, thereby cleaning the metal debris on the mold, preventing a large amount of debris from accumulating, reducing the difficulty of cleaning, saving labor costs, improving the processing accuracy in disguise, and extending the service life of the device. Example

[0026] In this embodiment, by inserting the collecting bin 10 into the inner side of the fixed frame 9, the metal debris falling from the chip bucket 7 can be caught, so that the debris can be collected. By grasping and pulling the handle 11, the collecting bin 10 can be pulled out of the fixed frame 9 to process the metal debris. The base frame 12 can improve the stability and prevent the collecting bin 10 from falling off from the fixed frame 9, so as to effectively collect the metal debris and prevent it from escaping into the air and causing air pollution. The aluminum sheet can be put into the mold for processing through the feed port 28. The clamping member 16 can limit the aluminum sheet to prevent its position from shifting.

The discharge hopper 27 can be used to guide the falling aluminum cover into the collection box, thereby improving work efficiency, preventing the finished products from being scattered, and saving labor costs.
[0027] The working principle of this embodiment is as follows: when in use, the aluminum sheet is first put into the mold from the feed port 28 for processing, the aluminum sheet can be limited by the clamp 16, the upper mold 21 is pushed down by a hydraulic press, the aluminum sheet in the first processing area 13 is shallowly stretched by the stretching workpiece 22, the aluminum sheet in the second processing area 14 is stamped and formed by the stamping workpiece 23, the aluminum cover formed in the third processing area 15 is cut off by the cutting workpiece 24, and the aluminum cover falls from the discharge port 25. The discharge hopper 27 can be used to guide the falling aluminum cover to fall into the collection box. During this process, the axial flow fan 6 is started and stopped regularly to suck the metal debris generated by the processing into the chip removal bin 3. When the axial flow fan 6 stops, the debris falls and slides from the chip removal bucket 7 into the collection bin 10. Finally, the handle 11 is grasped and pulled to pull the collection bin 10 out of the fixed frame 9, and the metal debris is centrally processed to complete the processing of the aluminum cover.
