Description

Technical Field

[0001] This utility model relates to the field of manufacturing technology, specifically to a cutting die blade block with rapidly adjustable gap. Background Technology

[0002] Currently, stamping dies are designed and developed based on the stamping and shearing principle, and are only designed for fixed material thicknesses. That is, after the die is developed, it can only be used for mass production of specific raw materials. When the process is exactly the same but the material thickness is different, another set of dies must be developed and processed. If the process is complex, such cost investment is acceptable. However, if it is a simple uncoiling and cutting process, it is not only very costly for a manufacturer to develop different dies for different material thicknesses, but also the dies must be replaced every time the material thickness is changed. This also results in a lot of wasted production time. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model proposes a cutting die blade block for quick gap adjustment, comprising an I-shaped blade block, wherein the four corners of the I-shaped blade block are respectively provided with a first cutting edge, a second cutting edge, a third cutting edge, and a fourth cutting edge, and bolt locking through holes are provided on both sides of the I-shaped blade block, and a Z-shaped positioning key is embedded in the lower notch of the I-shaped blade block.

[0004] As a further improvement of this utility model, a Z-shaped positioning key is movably embedded in the lower notch of the I-shaped blade block.

[0005] The beneficial effects of this utility model are: A single shearing die can be quickly adjusted to accommodate different gaps, thus meeting the shearing requirements of materials of varying thicknesses.

[0006] The core mechanism consists of an I-shaped cutting block and a Z-shaped positioning key. Through different combinations of the two, it can provide 12 different blanking gaps to meet the blanking requirements of all sheet thicknesses in a stamping plant.

[0007] It can be applied to the design and development of stamping dies and the mass production of corresponding shearing dies, effectively reducing the cost of die development, reducing the time lost due to die replacement during production, and thus improving production efficiency.

[0010] To facilitate understanding of this application, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate the described embodiments. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this application.

[0011] like Figure 1 As shown, a cutting die blade block for quick gap adjustment includes an I-shaped blade block 5. The four corners of the I-shaped blade block 5 are respectively provided with a first cutting edge 1, a second cutting edge 2, a third cutting edge 3, and a fourth cutting edge 4. Both sides of the I-shaped blade block 5 are provided with bolt locking through holes 7. A Z-shaped positioning key 6 is movably embedded in the lower notch of the I-shaped blade block 5.

[0012] The I-shaped cutter block 5 is the main structural component used to achieve rapid adjustment of the clearance. All four edges of this cutter block are cutting edges, namely cutting edge 1, cutting edge 2, cutting edge 3, and cutting edge 4. By flipping and installing the I-shaped cutter block 5, four different clearances can be quickly switched. Furthermore, the upper and lower positioning grooves of the I-shaped cutter block 5 are eccentrically treated to different degrees, so that when the four edges of the cutter block are used as cutting edges, they form four different dimensions with the cutting edge position of the upper die, thus achieving four different punching clearances.

[0013] The Z-shaped positioning key 6 is a crucial component ensuring the relative positional accuracy of the I-shaped cutter block 5 within the lower die. It also ensures that the I-shaped cutter block 5 does not shift relative to the die under stress during shearing operations, thus guaranteeing smooth die operation. Furthermore, by rotating the Z-shaped positioning key 6, the number of quickly switchable gaps for the I-shaped cutter block 5 can be doubled; that is, the I-shaped cutter block 5 and the Z-shaped positioning key 6 working together can achieve rapid switching of 12 gaps. By modifying the traditional rectangular positioning key into a Z-shape and flipping it, the four gaps of the I-shaped cutter block 5 can be expanded to 12. In other words, the four gaps of the I-shaped cutter block 5 itself, plus the eight gaps added by rotating the Z-shaped positioning key 6, work together to achieve rapid switching of 12 gaps, thereby meeting the factory's production needs for a wider range of sheet metal thicknesses.

[0014] In use, the I-shaped blade block 5 and the Z-shaped positioning key 6 are fixed to the lower mold of the mold by fixing bolts. When the thickness of the material to be cut changes, the fixing bolts are removed and the I-shaped blade block 5 and the Z-shaped positioning key 6 are rotated and flipped to create the gap required for the corresponding thickness. Then the fixing bolts are tightened to start the cutting production.

[0015] like Figures 2-4 As shown, by changing the usage of the Z-shaped positioning key 6, three different gaps can be achieved for a single cutting edge. At the same time, by flipping the I-shaped cutting block 5 horizontally or in a mirror image, all four cutting edges can be used as blanking cutting edges. Combined with the usage of the Z-shaped positioning key 6 above, a total of 12 gaps can coexist in one blanking die and can be quickly switched.

[0016] exist Figure 2 In the middle, the Z-shaped positioning key 6 is in its initial placement state, which corresponds to the first type of gap; Figure 3 In the middle, after rotating the Z-shaped positioning key 6 90 degrees and placing it, the gap changes for the first time, corresponding to the second type of gap; in Figure 4 Inside, the Z-shaped positioning key 6 is placed after being mirrored and flipped, and the gap changes again, that is, a third change occurs, corresponding to the third type of gap.

[0017] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
