Detailed Description
The invention is further described below with reference to fig. 2 to 6:
as shown in fig. 2, the present invention provides a scrap-jumping prevention stamping die, which includes an upper die and a lower die that are relatively movable up and down.
The upper die comprises an upper die base 1, a stripping assembly, an elastic element 8, a mounting plate and a punch 7. The upper die holder 1 is connected with the stripping assembly through a connecting element 2, and the upper die holder 1 and the stripping assembly can move up and down relatively. The stripping component comprises a stripping plate 6 and a sub-baffle 5, and the stripping plate 6 is fixedly connected below the sub-baffle 5 and used for pressing. The connecting element 2 is a bolt, one end of the connecting element is connected with the upper die holder 1, and the other end of the connecting element penetrates through the mounting plate to be connected with the sub-baffle 5.
The mounting plate is arranged between the upper die holder 1 and the stripping assembly and is fixedly connected with the upper die holder 1. Specifically, the mounting panel includes upper padding plate 3 and splint 4, and the upside and the upper die base 1 fixed connection of upper padding plate 3, downside and splint 4 fixed connection.
The elastic element 8 is connected with the upper die base 1 and can press the stripping component along the up-down direction. Specifically, the elastic element 8 penetrates through the mounting plate, one end of the elastic element is fixedly connected with the upper die holder 1, and the other end of the elastic element is pressed above the sub-baffle 5. The elastic element 8 may be in a compressed state at all times.
The punch 7 can move up and down to penetrate through the stripping assembly and is connected with the mounting plate for punching. Specifically, the upper end of the punch 7 passes through the clamping plate 4 and is fixedly connected with the upper backing plate 3. The lower end of the punch 7 penetrates through the stripper plate 6 and the sub-baffle 5 and can extend downwards from the stripper plate 6.
The lower die is provided with a blanking blade 11 matched with the punch 7 and a waste material channel 17 communicated with the blanking blade 11. The blanking edge 11 is used for forming a product in cooperation with the punch 7, and the scrap channel 17 is used for discharging the scrap 16 formed by blanking. Referring to fig. 3, the blanking blade 11 has a blanking section with an inverted frustum shape, i.e. the transverse dimension (e.g. radius) of the lower portion of the blanking section is smaller than the transverse dimension of the upper portion. The blanking section can be in the shape of an inverted cone frustum or an inverted multi-pyramid frustum. In this embodiment, the punched section has an inverted truncated cone shape. When blanking, the formed scrap 16 is caught at a position where the transverse dimension of the blanking section is minimum, and does not jump out from above the lower die, so that the scrap-jumping prevention stamping die can be prevented from being damaged at the time of continuous blanking.
The lower die comprises a lower die plate 14, a lower die base 12, a lower cushion plate 13 and a lower die knife edge inlet block 15, wherein the lower cushion plate 13 is fixedly installed above the lower die base 12, the lower cushion plate 14 is fixedly installed above the lower cushion plate 13, and the radiuses of the lower cushion plate 14 and the lower cushion plate 13 are approximately equal and smaller than the radius of the lower die base 12. The lower die blade insert 15 is mounted in the lower die plate 14, and the blanking blade 11 is opened on the lower die blade insert 15. Specifically, the lower die blade insert 15 and the lower die plate 14 may be detachably connected to facilitate replacement of different lower die blade inserts 15 for different products. The waste channel 17 is opened on the lower die holder 12 and the lower backing plate 13 and penetrates through the lower die holder 12 and the lower backing plate 13, and the radius of the waste channel 17 can be larger than that of the blanking blade 11, so that the waste 16 can be discharged easily. The scrap channel 17 is located just below the blanking edge 11 and, when the scrap 16 is punched from the stamping part 10, it can fall down into the scrap channel 17 and be discharged again.
Referring to fig. 2, the blanking blade 11 further includes a scrap section below the blanking section, the scrap section having a frustum shape and communicating with the scrap passage 17 for discharging the scrap 16 to the scrap passage 17. Because the punching section is in the shape of an inverted frustum and the waste section is in the shape of a frustum, the junction of the punching section and the waste section is the minimum transverse dimension (radius), and the waste 16 is clamped at the junction of the punching section and the waste section. The taper of the scrap section is greater than the taper of the blanking section.
Referring to fig. 1, when the upper die is in a free state (i.e., not stamped state), a gap is formed between the mounting plate and the stripper plate, and the lower end of the punch 7 is located in the stripper plate, that is, the lower end of the punch 7 does not protrude from the lower surface of the stripper plate 6. When the upper die is in a free state, a gap is formed between the clamping plate 4 and the sub baffle plate 5. The elastic element 8 is a gas spring, which may be a nitrogen gas spring, for example.
When stamping is carried out on the stamping part 10 by the anti-jumping waste stamping die, the stamping part 10 is firstly placed between an upper die and a lower die, the front end and the rear end of the stamping part are limited and fixed through a stamping part pressing limiting mechanism A, an upper die base 1 is pressed down under the action of a punch press, and a stripping component is pressed down along with the upper die base. As the upper die holder 1 continues to be pressed down, the stripper plate 6 presses the stamping 10 against the lower die plate 14. The upper die holder 1 continues to press downwards, the elastic element 8 starts to compress, the punch 6 extends out of the stripper plate 6 and is matched with the blanking blade 11 to blank the punch 10, and the blanking shape is the shape of the punch 7. During the downward movement of the punch 7, the punch 10 is first blanked, by the action of the blanking edge 11, forming a slug 16. In the process, because the blanking blade 11 is in the shape of an inverted frustum, when the punch 7 drives the scrap 16 to move downwards, the blanking blade 11 extrudes the periphery of the scrap 16 to deform the scrap, and the shape of the blanking blade 11 changes along with the shape of the scrap.
When the upper die is completely closed, namely the clamping plate 4 is completely attached to the sub baffle 5, the downward movement of the upper die is finished, meanwhile, the movement of the punch 7 is finished, the punch 7 drives the waste 16 formed by the blanking stamping part 10 to the lower end part of the blanking section of the blanking blade 11, so that the waste 16 formed by the blanking stamping part 10 is clamped by the narrowest part of the blanking blade 11, and the waste 16 cannot be ejected upwards out of the blanking blade 11 under the action of the punch 16, so that the waste can be prevented from jumping.
Then, the upper die moves upwards under the drive of the punch press, firstly, the punch 7, the upper die holder 1, the upper base plate 3 and the clamping plate 4 move upwards, the elastic element 8 resets, when the punch 7 returns to a proper position in the stripper plate 6, the sub baffle 5 and the stripper plate 6 also start to move upwards under the drive of the connecting element 2, when the punch press drives the upper die to move to the uppermost limit, the stamping part 10 is detached from the stamping part pressing limiting mechanism A, so that a blanking process is completed, and the repeated movement enables the die to continuously work.
According to the scrap jumping prevention stamping die provided by the invention, the blanking section of the blanking notch is set to be in the inverted frustum shape, so that scrap jumping can be effectively prevented, and the die is prevented from being damaged.
