[0002] The magnetic guide sheet is an important part on the horn. The processing of the magnetic guide sheet in the prior art mainly adopts precision machine tools or molds for production, and its existing problems are: on the one hand, the c...

Method used

It can be seen that, in the lower mold structure of the present invention, an adjusting mechanism is adopted to adjust the horizontal displacement of the die 9, so that the gap between the die 9 and the punch 6 can be even, so as to improve the precision of the blanking magnetic sheet. The smoothness and precision of the section, and the use of a stripping mechanism to strip the punch 6 relative to the die 9 after stamping, avoids the problem of the upper mold being stuck when unloading.

Referring to shown in Fig. 1, the lower die structure of a kind of magnetic sheet blanking mold provided by the invention comprises die 9 and lower template 11, wherein, die 9 is installed on the ...

Abstract

The invention relates to the technical field of dies and discloses a lower die structure of a magnetic-conducting piece blanking die. The lower die structure comprises a female die and a lower formwork, and the female die is installed on the lower formwork. The lower die structure further comprises an adjusting mechanism and a material-stripping mechanism, wherein the adjusting mechanism is installed on the lower formwork to be used for adjusting horizontal displacement of the female die, and the material-stripping mechanism is arranged at the upper end of the female die to be used for material stripping after stamping. The adjusting mechanism comprises an adjusting ring and a plurality of adjusting screws, wherein the adjusting ring is installed on the lower formwork and located on the outer side of the female die, and the adjusting screws are installed in the circumferential direction of the adjusting ring. According to the lower die structure, on one hand, the adjusting mechanism is adopted to adjust horizontal displacement of the female die, so that intervals between the female die of the whole die and a male die are uniform so as to improve cross section smoothness and precision of blanking magnetic-conducting pieces, on the other hand, the material-stripping mechanism is adopted to perform material stripping, and the problem of blockage in material discharging is solved.

[0013] The invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0014] Refer to figure 1 As shown, the lower mold structure of a blanking mold for a magnetic conductive sheet provided by the present invention includes a concave mold 9 and a lower template 11, wherein the concave mold 9 is mounted on the lower template 11, and the present invention also includes the lower mold The adjustment mechanism on 11 is used to adjust the horizontal displacement of the concave mold 9 and the unloading mechanism is arranged on the upper end of the concave mold 9 for stripping after punching. In this way, on the one hand, the present invention uses an adjusting mechanism to adjust the horizontal displacement of the concave mold, so that the gap between the concave mold 9 and the convex mold of the entire mold can be made uniform, so as to improve the surface finish and accuracy of the punching magnetic conductive sheet. The stripping mechanism is used for stripping, which avoids the phenomenon of jamming during discharge.

[0015] Specifically, the adjustment mechanism for adjusting the horizontal displacement of the concave mold 9 includes an adjustment ring 10 installed on the lower template 11 and located outside the concave mold 9, and a plurality of adjustment screws 12 installed in the circumferential direction of the adjustment ring 10. In addition, the die 9 and the adjusting ring 10 are both installed on the lower template 11 by screws, and there is a gap between the screw and the screw hole on the die 9 and the screw hole on the adjusting ring 10, so that the adjustment When the screw 12 is adjusted, the end of the adjusting screw 12 can be made to abut the side surface of the concave mold 9 so that the concave mold 9 can be fine-tuned for displacement in the horizontal direction.

[0016] Specifically, the aforementioned stripping mechanism includes a guide plate 8 mounted on the upper end of the adjusting ring 10, the guide plate 8 is located at the upper end of the die 9, and the guide plate 8 is also provided with a guide hole, and the guide plate 8 needs to be made of rigid material. During use, the guide plate 8 can block the material from the upper mold, which solves the problem of jamming of the upper mold during unloading.

[0017] Refer to figure 2 with image 3 As shown, it is a structural diagram of a magnetic sheet blanking mold composed of a lower mold structure of the present invention. The mold also includes an upper mold device corresponding to the above-mentioned lower mold structure, wherein the upper mold device includes a mold handle 1, an upper template 2. The outer guide column 3, the upper backing plate 4, the fixed plate 5 and the punch 6, the mold handle 1 is installed on the upper mold plate 2, and the upper mold plate 2 can be mounted on the lower mold device through the outer guide pillar 3, and the upper pad The board 4 is installed at the lower end of the upper template 2, the fixed board 5 is installed at the lower end of the upper backing board 4, and the punch 6 is installed on the lower end of the upper backing board 4 through the fixed board 5.

[0018] It can be seen that the lower mold structure of the present invention adopts an adjusting mechanism to adjust the horizontal displacement of the concave mold 9 so that the gap between the concave mold 9 and the convex mold 6 can be made uniform, so as to improve the smoothness and smoothness of the section of the punching magnetic conductive sheet. Accuracy, and a stripping mechanism is used to strip the punch 6 relative to the recess 9 after punching, so as to avoid the problem of the upper mold jamming during discharge.

[0019] The following is attached Figure 1 ~ Figure 3 The working principle of the magnetic conductive sheet blanking mold composed of the lower mold structure of the present invention is further explained:

[0020] The blanking die for the magnetic conductive sheet composed of the lower die structure of the present invention is blanked with negative gap (that is, the diameter of the concave die 9 is slightly larger than the diameter of the convex die 6). When working, install the entire die on the press. When adjusting the die, The gap between the female mold 9 and the male mold 6 is adjusted by adjusting the screw 12 to make it uniform. As a result, the slider of the press drives the punch 6 to punch down the blank 7 to obtain products with higher punching section finish and precision. When the die is working, the upper die moves down with the press for punching. When the press reaches the bottom dead center, the punch just breaks the product (due to negative gap punching, the punch 6 cannot enter the die 9) , The press moves up, and the sheet material stuck on the punch 6 is unloaded through the rigid guide plate 8, and the press returns to the top dead center to complete a working cycle.

[0021] Although the embodiments of the invention are described in conjunction with the drawings, the patent owner can make various changes or modifications within the scope of the appended claims, as long as they do not exceed the scope of protection described in the claims of the invention. Within the scope of protection.
