Description
Technical Field
[0001] The utility model relates to the technical field of closed-loop punching dies, and more specifically, to a closed-loop punching dies with a gradient blade shape. Background Art
[0002] Punching die is a type of punching die, which uses a closed-loop punching knife to punch out the sheet of the desired outline. The punching knife is generally made by bending a strip of steel, so there must be a joint between the head and the tail of the punching knife. If the head and the tail are not tightly connected, it will cause adhesion at this point during punching, that is, incomplete punching and unsmooth material removal. Therefore, the key point of manufacturing the punching knife is to ensure that it forms a closed-loop blade. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] like Figures 1 to 5As shown, the utility model provides a closed-loop punching die with a gradient blade shape, including a punching knife 1, a connection head end 2 is fixedly installed in front of the punching knife 1, a mounting opening 3 is opened inside the connection head end 2, a fixing block 1 4 is fixedly installed above the connection head end 2, a connection tail end 5 is fixedly installed in front of the punching knife 1, the connection tail end 5 is located on the right side of the connection head end 2, an insert block 6 is fixedly installed on the left side of the connection tail end 5, a fixing block 2 7 is fixedly installed above the connection tail end 5, a bolt 8 is meshed inside the fixing block 2 7, a nut 9 is meshed on the surface of the bolt 8, and a blade 10 is opened at the bottom of the punching knife 1.
[0028] The plug block 6 is located inside the installation opening 3. Since the connection tail end 5 is fixedly connected to the plug block 6, the plug block 6 is limited and fixed inside the installation opening 3, so that the connection tail end 5 will not be distorted or shaken back and forth when the blade 10 is cutting. At the same time, the bolt 8 is meshed with the fixing block 1 4. The bolt 8 is meshed with the fixing block 1 4 and the fixing block 2 7, so that the distance between the fixing block 1 4 and the nut 9 is shortened, so that the right side of the connection head end 2 is fitted with the left side of the connection tail end 5, achieving a fully connected effect.
[0029] A bevel block 11 is fixedly mounted on the left side of the punching knife 1 , and a bevel blade 12 is provided at the bottom of the bevel block 11 .
[0030] The oblique edge 12 is connected to the blade 10 and is mainly used to punch out the electronic label of the required shape to achieve an irregular shape.
[0031] A support pad 13 is fixedly installed on the right side of the punching blade 1 , a telescopic rod 14 is fixedly installed on the right side of the support pad 13 , and a spring 15 is sleeved on the outer side of the telescopic rod 14 .
[0032] The support pad 13 is in the shape of a rectangular parallelepiped, and its main function is to support the right side of the punching blade 1 through the telescopic rod 14 and the spring 15 to prevent the punching blade 1 from being distorted due to its thinness during the punching process.
[0033] A buffer pad 16 is sleeved on the outer side of the punching blade 1 , and a connecting hole 17 is opened inside the right side of the buffer pad 16 , through which the spring 15 and the telescopic rod 14 pass.
[0034] The diameter of the connecting hole 17 is greater than the diameters of the telescopic rod 14 and the spring 15. The main function of the buffer pad 16 is to provide a lateral buffering effect for the punching knife 1 on the outside of the buffer pad 16 to prevent the punching knife 1 from being broken due to a large force.
[0035] The outer side of the buffer pad 16 is sleeved with a bottom plate 18 , the punching blade 1 , the telescopic rod 14 and the spring 15 are all located inside the bottom plate 18 , and the inside of the bottom plate 18 is hollow.
[0036] The bottom plate 18 is fixedly connected to the telescopic rod 14 and the spring 15, and its main function is to provide support for the entire device to ensure that the punching knife 1 can perform punching and cutting normally.
[0037] The installation opening 3 is in the shape of a rectangular parallelepiped and is located inside the connection head end 2 . The punching knife 1 is surrounded by the connection head end 2 , the connection tail end 5 and the inclined block 11 to form a closed loop.
[0038] The installation opening 3 is inserted into the insert block 6 so that the connection head end 2 and the bottom connection of the connection tail end 5 will not deviate, so that the electronic tag will not stick after punching.
[0039] Among them, the bolt 8 is located above the connecting head end 2 and the connecting tail end 5, and the nut 9 is located on the left side of the fixing block 4.
[0040] The nut 9 has a certain limiting effect on the fixing block 4. When the device works for a long time, the engagement between the fixing block 4 and the bolt 8 may become loose. At this time, the nut 9 will block it, thereby preventing the fixing block 4 and the bolt 8 from loosening, resulting in a loose connection between the connection head end 2 and the connection tail end 5.
[0041] The buffer pad 16 is in a broken shape as a whole, and the broken part is in front of the connection between the connecting head end 2 and the connecting tail end 5 .
[0042] The main function of the buffer pad 16 not being connected at the first position is to leave a certain space for the disassembly of the connection head end 2 and the connection tail end 5, so as to prevent the situation that it is difficult to disassemble the connection head end 2 and the connection tail end 5 when grinding the blade 10.
[0043] The working principle and use process of this utility model:
[0044] First, insert the insert block 6 into the installation opening 3, and then mesh the fixing block 1 4 and the fixing block 2 7 through the bolt 8, so that the distance between the connection head end 2 and the connection tail end 5 is shortened, until the right side of the connection head end 2 contacts the right side of the connection tail end 5, so that the connection head end 2 and the connection tail end 5 are tightly connected, so that the punching knife 1, the connection head end 2 and the connection tail end 5 form a closed loop, so that there is no gap between the connection head end 2 and the connection tail end 5, so that there is no adhesion during punching;
[0045] Secondly, the buffer pad 16 is sleeved on the outside of the punching knife 1 and connected to the bottom plate 18 at the same time, so as to ensure that when the device is punching, the support pad 13 and the buffer pad 16 can buffer the punching knife 1, so as to prevent the punching knife 1 from bending and breaking due to the high pressure encountered during punching;
[0046] Finally, the buffer pad 16 is in a broken state at the connection between the connecting head end 2 and the connecting tail end 5, which can leave a certain space for the disassembly of the connecting head end 2 and the connecting tail end 5, thereby preventing the situation in which it is difficult to disassemble the connecting head end 2 and the connecting tail end 5 when the blade 10 is repaired and polished.
