DETAILED DESCRIPTION

[0027] The utility model will be further described in combination with the drawings and specific embodiments, so that the technical idea of the utility model claimed is more clearly understood. Only this declaration, the up, down, left, right, front, back, inside, outside and other orientation words appearing in the text or about to appear in the utility model, only with the drawings of the utility model as the base, it is not the specific limitation of the utility model.

[0028] As Figures 1 to 9 Indicated, the utility model embodiment of an aluminum plate blanking die, including die seat 1 and install on die seat 1 and be used for to aluminum plate stamping blanking cutter 2. Actually, the die seat 1 is used to install the aluminum plate blanking die of the utility model to the external punch press, the layout of blanking cutter 2 is customized according to the aluminum plate shape and size required to cut, ensure that in blanking operation can accurately contact with aluminum plate, thereby realizing the accurate cutting of aluminum plate. The detailed configuration and layout of blanking cutter 2 on die seat 1 is to ensure the high efficiency and accuracy of blanking process, and the specific setting of blanking cutter 2 on die seat 1 will not be described one by one.

[0029] The aluminum plate blanking die provided by the utility model further comprises an oil injection head 3 installed on the die holder 1 and used for spraying lubricating oil on the blanking tool 2 and a gas injection head 4 installed on the die holder 1 and used for spraying gas on the blanking tool 2. In fact, the spraying direction of the oil injection head 3 and the spraying direction of the gas injection head 4 are both directed to the blanking tool 2. The oil injection head 3 can be communicated with a liquid storage tank containing lubricating oil through an oil pipeline and a liquid pump, so as to spray oil on the blanking tool 2. The gas injection head 4 can be communicated with a gas supply device through a gas pipeline, so as to spray gas on the blanking tool 2.

[0030] The specific working principle of the aluminum plate blanking die is as follows: before the external punch prepares to drive the die to implement the blanking action on the aluminum plate, the oil injection head 3 provided by the die will spray lubricating oil on the blanking tool 2 in advance, the lubricating oil can form a protective film between the blanking tool 2 and the aluminum plate, so as to reduce the friction when the two are in contact, thereby effectively reducing the risk of cracking of the aluminum plate in the blanking process and improving the qualified rate of the product. After the blanking action is completed, the gas injection head 4 will spray gas on the blanking tool 2. The function of this gas is to remove the metal debris adhered to the blanking tool 2. By blowing away these debris, it can prevent them from interfering with the blanking action in the subsequent blanking process, thereby ensuring the stability of the blanking quality. In addition, this measure can also reduce the damage of the debris to the blanking tool 2, thereby prolonging the service life of the blanking tool 2.

[0031] The aluminum plate blanking die can reduce the cracking of the aluminum plate during blanking, improve the qualified rate of the product, prevent the debris from interfering with the blanking process, improve the blanking quality, reduce the damage to the blanking tool 2 and prolong the service life of the blanking tool 2 by the cooperation of the die holder 1, the blanking tool 2, the oil injection head 3 and the gas injection head 4.

[0032] Specifically, the oil injection head 3 is preferably arranged on one side of the blanking tool 2, the oil injection head 3 is provided with an oil injection nozzle 5 with a spraying direction directed to the blanking tool 2, the oil injection nozzle 5 is provided with a circular arc groove 6 with an opening directed to the blanking tool 2 and a communication hole 7 communicating the oil outlet of the oil injection head 3 with the circular arc groove 6. In fact, when the oil injection head 3 is started and sprays lubricating oil, the oil liquid will form a diverging oil mist after leaving the oil injection head 3. This design enables the lubricating oil to adhere uniformly to the blanking tool 2. The lubricating oil enters the circular arc groove 6 through the communication hole 7 and is further ensured to be uniformly dispersed and limited in the diffusion range under the guidance and wrapping of the groove, not only enabling the lubricating oil to adhere more targetedly to the key parts of the blanking tool 2, but also improving the lubricating efficiency and ensuring the smoothness in the blanking process and the protection of the blanking tool 2.

[0033] More specifically, the circular arc groove 6 is preferably arranged to extend vertically, taking into account that the punching knife 2 will move up and down during the punching process and come into contact with the aluminum plate, wherein one vertical face of the punching knife 2 is the working face that comes into contact with the aluminum plate. By designing the circular arc groove 6 in the form of vertical extension, the lubricating oil can be more accurately sprayed onto the working side of the punching knife 2. Preferably, the central angle of the arc edge of the cross section of the circular arc groove 6 is greater than 90 degrees and less than 180 degrees. Since the central angle is greater than 90 degrees, the lubricating oil will be concentratedly guided when passing through the circular arc groove 6, thereby more effectively covering the working face of the punching knife 2 and enhancing the lubricating effect. At the same time, the central angle less than 180 degrees avoids excessive concentration of lubricating oil and further diffusion. If the central angle reaches or exceeds 180 degrees, the lubricating oil may be excessively concentrated in the circular arc groove 6, resulting in uneven dispersion to the entire working face of the punching knife 2. By limiting the central angle below 180 degrees, it can be ensured that the lubricating oil can maintain a certain divergence while covering the punching knife 2, so as to achieve more extensive lubricating coverage.

[0034] It should be noted that the mold base 1 is preferably provided with a first connecting vertical plate 8, which is provided with a guide hole 9 and a threaded hole 10 which is perpendicular to and communicates with the guide hole 9, the axis of the guide hole 9 is parallel to the spraying direction of the oil spraying head 3, the oil spraying head 3 is provided with a guide rod 11 which is in sliding connection with the guide hole 9, and the threaded hole 10 is threadedly connected with a locking bolt 12 which is used to abut against the guide rod 11. As Figure 3 shown, the operator can release the guide rod 11 by rotating the locking bolt 12, and then slide the guide rod 11 to adjust the distance between the oil spraying head 3 and the punching knife 2, and optimize the oil spraying effect. After adjustment, the locking bolt 12 is tightened again to fix the guide rod 11, so as to ensure the stability of the position of the oil spraying head 3, meet different punching requirements, and improve the punching efficiency and quality.

[0035] It is worth mentioning that, as Figure 2 shown, the two air blowing heads 4 are preferably used to blow air to one punching knife 2, and the punching knife 2 is arranged in the middle of the two oppositely arranged air blowing heads 4, that is, when blowing air, the two air blowing heads 4 blow air to the punching knife 2 in the middle position at the same time, so that the two air flows meet on the working face of the punching knife 2 to generate turbulent flow effect, which helps to more effectively separate the metal scraps from the surface of the punching knife 2, because the mutual impact and chaotic movement of the air flows can increase the possibility of the scraps being blown away from the surface of the punching knife 2. Such air flow layout not only improves the efficiency of blowing air to remove scraps, but also ensures the cleanliness of the punching knife 2, thereby maintaining the punching quality and reducing the potential damage to the punching knife 2. Through the synergistic effect of the two air blowing heads 4, the working performance of the punching knife 2 can be more reliably maintained, and the service life of the punching knife 2 can be prolonged.

[0036] Specifically, as Figure 6As shown, the jet head 4 is preferably provided with a jet nozzle 13 whose jet direction is towards the blanking tool 2, and the jet nozzle 13 is provided with a strip-shaped gas outlet hole 14 which is arranged in an up-down direction and whose opening is towards the blanking tool 2. Since one vertical surface of the blanking tool 2 is the working surface which is in contact with the aluminum plate, the gas jetted out of the strip-shaped gas outlet hole 14 arranged in an up-down direction can more easily cover the working surface of the blanking. Through the arrangement of the strip-shaped gas outlet hole 14 arranged in an up-down direction, the gas can uniformly and continuously act on the whole area of the blanking tool 2 which is in contact with the aluminum plate. Such comprehensive gas coverage helps to more thoroughly remove the metal scraps attached to the working surface of the blanking tool 2, thereby improving the cleanliness and efficiency of the blanking.

[0037] More specifically, the die holder 1 is preferably provided with a second connecting vertical plate 15 which is provided with a mounting hole 16, and the jet head 4 is provided with a connecting stud 17 which is used to pass through the mounting hole 16, and the connecting stud 17 is threadedly connected with two connecting nuts 18 which respectively abut against two sides of the second connecting vertical plate 15. As shown, Figure 5 and Figure 7 As shown, first, the abutment between the connecting nut 18 and the second connecting plate is loosened, so that the connecting nut 18 no longer abuts against the second connecting plate. After the connecting nut 18 is loosened, the operator can adjust the position of the jet head 4 by using the cooperation between the connecting stud 17 and the mounting hole 16, so as to change the relative position between the jet head 4 and the blanking tool 2. This adjustment process allows the operator to accurately position the jet head 4 according to actual needs, so as to ensure that the relative position between the jet head 4 and the blanking tool 2 can satisfy the best blowing effect, thereby improving the removal efficiency of the metal scraps in the blanking process. After the adjustment is completed, the operator needs to tighten the connecting nut 18 again, so as to fix the position of the jet head 4 and ensure that it remains stable during the blanking process. Preferably, the mounting hole 16 is a long strip hole arranged in an up-down direction, so that the connecting stud 17 can be adjusted in an up-down direction within the mounting hole 16, so as to adjust the up-down position of the jet head 4, thereby adapting to different blanking requirements.

[0038] In addition, the aluminum plate blanking die of the utility model still preferably comprises a ring-shaped oil delivery pipe 19 which is arranged on the die holder 1, an oil storage tank 20 which is filled with lubricating oil, an oil pump 21 which is used to pump the lubricating oil in the oil storage tank 20 into the ring-shaped oil delivery pipe 19, a ring-shaped gas delivery pipe 22 which is arranged on the die holder 1, and an air compressor 23 which is in communication with the ring-shaped gas delivery pipe 22, the ring-shaped oil delivery pipe 19 is connected with a plurality of oil jet heads 3, and the ring-shaped gas delivery pipe 22 is connected with a plurality of jet heads 4. As shown, Figure 1 and Figure 8 As shown, the oil storage tank 20 and the oil pump 21 can be installed outside the die holder 1 and in communication with the ring-shaped oil delivery pipe 19 through a hose. Such arrangement allows the hose to have a certain length, so that when the die holder 1 moves up and down, the hose can stretch and contract along with it, thereby ensuring that the blanking tool 2 can continuously receive oil jet; similarly, as shown,Figure 1 and Figure 9 As shown in the figure, the air jet device can be installed outside the die holder 1 and connected with the air supply pipe through a hose to realize the air jet operation on the punching tool 2. Such design also allows the hose to have a certain range of movement when the die holder 1 moves, ensuring that the air jet system can flexibly blow the punching tool 2 to remove the metal debris generated in the punching process.

[0039] The above is only a specific embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
