Description

Technical Field

[0001] The invention relates to the field of mold structures, in particular to an inclined punching structure in an inclined mold of a hardware part. Background Art

[0002] At present, in the field of new energy vehicles, more and more hardware processing parts have more broken parts and high dimensional accuracy. Most of them are made of copper with a thickness of 1.0mm~1.2mm, and the mold breaking stroke is mostly close to 30mm. To achieve stable mass production, very high breaking dimensional accuracy is required.

[0003] When existing hardware parts need to be formed into a bevel after being broken, most of them use a chamfered mold structure to achieve a bevel with a precision of 2.5°+1° / 0. However, when chamfering, the product material is easily squeezed onto the bevel, which may produce iron wire and increase the error at the bevel. Secondly, the dimensions are unstable during the stamping process, and the dimensions of the bevel edge fluctuate greatly, resulting in a large fracture zone on the cut surface.

The terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0031] The preferred embodiments of the present invention will now be further described with reference to the accompanying drawings. Figures 1 to 3 As shown, a structure for oblique punching in a bevel die of a hardware part includes a hardware part 10 and a die body 20. An extension portion 11 for oblique punching is extended along one side of the hardware part 10. One side of the extension portion 11 is integrally formed with the hardware part 10, and a protrusion 12 is provided on the other side away from the hardware part 10. The die body 20 includes a punch fixing block 100. The punch fixing block 100 is provided with a receiving cavity 110 for accommodating a bevel punch 200. The receiving cavity 110 forms a notch 120 on the punch fixing block 100. The bevel punch 200 protrudes from the punch fixing block 100 at the notch 120, and the bevel punch 200 can be lifted and lowered in the accommodating cavity 110. A supporting block 500 is provided below the punch fixing block 100, and an oblique punching space 300 is formed between the supporting block 500 and the bevel punch 200. The extended portion 11 of the hardware 10 is arranged in the oblique punching space 300, and the bevel punch 200 is inclined toward the notch 120 with the vertical direction of the punch fixing block 100 as the reference.

[0032] In the working state of this embodiment, the hardware 10 is first inserted into the oblique punching space 300 between the punch fixing block 100 and the supporting block 500, so that the extension portion 11 is located below the bevel punch 200, and then the bevel punch 200 is driven to move downward in the accommodating cavity 110. Since the bevel punch 200 is inclined toward the notch 120 with the vertical direction of the punch fixing block 100 as the reference, when the bevel punch 200 obliquely punches off the extension portion 11 from the hardware 10, a standard bevel will be left on the hardware 10.

[0033] Compared to the prior art, this application adds an oblique punch structure to the die to ensure that the punch is at an angle during stamping, thereby ensuring that the cross-section of the stamped product is oblique, solving the problem of stability in the oblique stamping of the hardware 10 and ensuring product quality. At the same time, the die has high strength and a faster stamping speed, which can greatly improve production efficiency.

[0034] On the basis of the above embodiment, Figure 4 、 Figure 5 and Figure 6 As shown, the bevel punch 200 includes a stroke portion 210 and an impact portion 220, the stroke portion 210 is arranged on one side of the impact portion 220, the accommodating chamber 110 includes a first chamber 111 and a second chamber 112 which are interconnected, the notch 120 is located in the second chamber 112, the stroke portion 210 is tightly accommodated in the first chamber 111, and the impact portion 220 is arranged in the second chamber 112. When the bevel punch 200 is inclined toward the notch 120 with the vertical direction of the punch fixing block 100 as a reference, one side of the impact portion 220 protrudes from the punch fixing block 100 at the notch 120, and the function of the stroke portion 210 is to guide the stroke of the bevel punch 200 in the punch fixing block 100 to ensure that the impact portion 220 can impact the extension portion 11 when it descends.

[0035] In some embodiments, combined Figure 4 and Figure 5 As shown, the volume of the stroke portion 210 is larger than that of the impact portion 220 , so that the stroke portion 210 has a better effect of guiding the stroke of the bevel punch 200 in the punch fixing block 100 .

[0036] On the basis of the above embodiment, Figure 2 and Figure 3As shown, connecting ends 230 are provided on both sides of the travel portion 210, and third chambers 113 are provided on both sides of the first chamber 111. When the travel portion 210 is tightly accommodated in the first chamber 111, the connecting ends 230 are located at the top of the third chamber 113. A resilient member 130 is provided between the connecting ends 230 and the third chamber 113. The function of the elastic member 130 is to disengage the bevel punch 200 from the support block 500 after the bevel punch 200 completes the punching action. The spring can provide power to the support block 500, enabling the support block 500 to promptly push out the hardware 10 mounted on the punch.

[0037] In some embodiments, combined Figure 4 and Figure 5 As shown, an impact block 221 is protruding downward from the bottom of the impact portion 220 , and the impact block 221 ensures that the energy of the impact portion 220 impacting the extension portion 11 when descending is more concentrated.

[0038] On the basis of the above embodiment, Figure 7 As shown in the figure, a discharge chute 510 is provided in the supporting block 500. The discharge chute 510 is inclined toward the notch 120 with the vertical direction of the supporting block 500 as the reference, and has the same slope as the vertical direction between the bevel punch 200 and the punch fixing block 100. In this way, when the bevel punch 200 obliquely punches the extension part 11 off the hardware 10, the extension part 11 will fall into the discharge chute 510.

[0039] On the basis of the above embodiment, Figure 5 and Figure 7 As shown, a guide groove 221a is provided on one side of the impact block 221, and a limit block 511 that cooperates with the guide groove 221a is provided in the discharge chute 510. When the bevel punch 200 obliquely punches off the extension portion 11 from the hardware 10, the impact block 221 will be inserted into the discharge chute 510 under the action of inertia, so that the limit block 511 is inserted into the guide groove 221a, which guides the stroke of the impact block 221 in the discharge chute 510, leaving a more standard bevel on the hardware 10.

[0040] In some embodiments, as Figure 3 As shown, a splint insert 400 is fixed on the top of the punch fixing block 100, and the splint insert 400 is used to drive the punch fixing block 100 to move downward together with a lifting mechanism (not shown in the drawing).

[0041] On the basis of the above embodiment, Figure 2As shown, on the side of the hardware 10, positioning rods 13 protrude outward along both sides of the extension portion 11. When the extension portion 11 of the hardware 10 is configured in the oblique punch space 300, the positioning rods 13 form abutment with the side wall of the punch fixing block 100 to ensure that the extension portion 11 is located below the impact block 221.

[0042] The foregoing exemplary embodiments are detailed, and the invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and all variations that come within the meaning and range of equivalents of the claims are intended to be embraced therein.
