[0002] Blanking is a processing technology in the manufacturing industry, mainly used to cut metal sheets into required shapes through impact force. It usually uses a punching press and a die. The material is placed on the die, and pressure is applied through a punch to cut it.

[0003] The waste generated during the blanking process is usually not convenient for direct recycling. Therefore, most blanking devices are equipped with a waste treatment module for collecting and treating waste after blanking. The waste treatment process takes a long time and is prone to generating powder chips. Summary of the Utility Model

[0028] The present utility model provides a blanking device. Figures 1 to 4 This is a specific embodiment of the blanking device provided by the present utility model.

[0029] Referring to Figures 1 to 4 , the blanking device includes a tearing assembly and a cutting assembly; the tearing assembly includes a first die 11 and a second die 12. The first die 11 is provided with a punching hole 111 that cooperates with the second die 12. The strip 10 is fixed to one side of the second die 12 close to the first die 11. The first die 11 is used to move towards the second die 12 to blank the strip 10; the cutting assembly includes a cutting knife 21 provided on one side of the second die 12. The first die 11 drives the blanked strip towards the cutting knife 21 to cut off the waste 20.

[0030] For convenience of explanation, taking Figure 1 as an example, the first die 11 is located above the second die 12, the cutting knife 21 is located on the circumferential side of the second die 12 and is in contact with the second die 12. After the strip 10 is blanked, it is formed into two parts. One part is the product obtained by blanking, which is located on the upper side of the second die 12, and the other part is the waste 20, which is located below the first die 11. After the first die 11 is blanked, it continues to push the waste 20 towards the cutting knife 21 to cut off the waste 20.

[0031] In this embodiment, during the process of the first die 11 moving towards the second die 12, the strip 10 can be blanked by the shearing force between the first die 11 and the second die 12. After blanking is completed, the first die 11 pushes the waste 20 to continue moving towards the cutting knife 21, and the cutting knife 21 cuts off the waste 20. Blanking and cutting off the waste 20 are completed in one step, and the waste 20 is processed quickly, which can greatly reduce the generation of powder chips.

[0032] The tearing assembly further includes a pressing member 13 sleeved on the first die 11, and the pressing member 13 is used to press and fix the strip 10 on the second die 12. In this embodiment, the pressing member 13 is slidably connected to the first die 11. By the pressing member 13, the strip 10 can be effectively fixed on the second die 12, preventing the strip 10 from displacing during the processing, ensuring the quality of the final product, reducing the defect rate, and improving the qualified rate of the finished product.

[0033] Wherein, both the first die 11 and the pressing member 13 are connected to a punching press, and the punching press provides power to drive the first die 11 and the pressing member 13 to move.

[0034] The pressing member 13 is provided with a limiting hole 131 for inserting into the first die 11, and a contact block 132 inserted into the punching hole 111 is arranged in the limiting hole 131. During blanking, the contact block 132 is in contact with the strip 10. In this embodiment, the contact block 132 and the second die 12 are arranged at an interval, and the interval therebetween is not greater than the thickness of the strip 10. The contact block 132 is used to press the strip 10 onto the second die 12 when the pressing member 13 moves towards the second die 12. Specifically, the punching press drives the pressing member 13 and the first die 11 to move towards the second die 12 at the same time. The contact block 132 first contacts the strip 10 and presses and fixes the strip 10 on the second die 12, and then the first die 11 contacts the strip 10 and blanks the strip 10.

[0035] The tearing component further includes a fixing member 14, and the fixing member 14 is provided with an installation groove 141. The second die 12 and the cutting knife 21 are installed in the installation groove 141. In this embodiment, the second die 12 and the cutting knife 21 are installed in one groove and are in mutual contact, which can ensure that the cutting knife 21 cuts off the waste material 20 cut off during the blanking process. Both the second die 12 and the cutting knife 21 are in contact with the side wall of the installation groove 141, so as to provide a fixing effect on the second die 12 and the cutting knife 21 through the installation groove 141, which can effectively reduce the movement or displacement of the second die 12 and the cutting knife 21 during use and improve the blanking accuracy; and the fixing method through the installation groove 141 has a simple structure.

[0036] A clamping groove 142 is provided on the side of the installation groove 141, and the second die 12 is provided with a clamping block 121 that is engaged with the clamping groove 142. In this embodiment, through the engagement of the clamping block 121 and the clamping groove 142, the second die 12 is further fixed, the stability of the second die 12 is increased, and it is ensured that the second die 12 does not displace during the blanking process, thereby improving the blanking accuracy.

[0037] The second die 12 is located at the bottom side of the first die 11. Guide blocks 15 are provided on the bottom sides of the second die 12 and the cutting knife 21. First inclined surfaces 151 are provided on the left and right sides of the guide block 15, and the first inclined surfaces 151 are inclined outward from top to bottom. In this embodiment, when the waste material 20 is cut off by the cutting knife 21, the waste material 20 falls on the first inclined surface 151 and then slides downward on the first inclined surface 151. The first inclined surface 151 can reduce the falling speed of the waste material 20 and prevent a large amount of powder from being blown up due to the friction between the waste material 20 and the air during the falling process.

[0038] Second inclined surfaces 143 that are inclined outward from top to bottom are provided on the left and right sides of the fixing member 14, and the second inclined surfaces 143 are located below the first inclined surfaces 151. In this embodiment, when the waste material 20 slides out from the first inclined surface 151, it can fall on the second inclined surface 143 and continue to slide downward on the second inclined surface 143 to reduce the falling speed of the waste material 20 and prevent a large amount of powder from being blown up due to the friction between the waste material 20 and the air during the falling process.

[0039] The present utility model also proposes a blanking device. The blanking device includes a blanking device, and the specific structure of the blanking device refers to the above embodiment. Since the blanking device proposed by the present utility model includes all the solutions of all the above embodiments of the blanking device, therefore, it has at least the same technical effects as the blanking device, and will not be elaborated one by one here.

[0040] The above are only alternative embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the inventive concept of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
