[0022] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0023] The preferred embodiments of the present invention are now further described in conjunction with the accompanying drawings. Figures 1 to 3 As shown, a bevel punching structure for a hardware component in a bevel die includes a hardware component 10 and a die body 20. An extending portion 11 for bevel punching is extended along one side of the hardware component 10. One side of the extending portion 11 is integrally formed with the hardware component 10, and a protrusion 12 is provided on the other side away from the hardware component 10. The die body 20 includes a punch fixing block 100. The punch fixing block 100 includes an accommodating cavity 110 for accommodating a bevel punch 200. The accommodating cavity 110 forms a notch 120 on the punch fixing block 100. The bevel punch 200 protrudes from the notch 120 of the punch fixing block 100, and the bevel punch 200 can be lifted and lowered in the accommodating cavity 110. A supporting block 500 is arranged 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 extending 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 a reference.

[0024] 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 respect to the vertical direction of the punch fixing block 100, when the bevel punch 200 obliquely punches the extension portion 11 off the hardware 10, a standard inclined surface will be left on the hardware 10.

[0025] Compared with the prior art, the present invention adds an oblique punch structure in the die to ensure that the punch is at an angle when punching, thereby ensuring that the cross section of the punched product is oblique, solving the problem of the stability of the oblique punching of the hardware 10 and ensuring the product quality. At the same time, the die has high strength and the punching speed is accelerated, which can greatly improve production efficiency.

[0026] On the basis of the above embodiments, 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 from 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.

[0027] In some embodiments, in combination 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 .

[0028] On the basis of the above embodiments, Figure 2 and Figure 3As shown, connecting ends 230 are respectively provided on both sides of the travel portion 210, and third chambers 113 are respectively provided on both sides of the first chamber 111. When the travel portion 210 is tightly accommodated in the first chamber 111, the connecting end 230 is located at the top of the third chamber 113, and a resetting elastic member 130 is provided between the connecting end 230 and the third chamber 113. The function of the elastic member 130 is to separate the bevel punch 200 from the support block 500 after the bevel punch 200 completes the punching action. The spring can provide power for the support block 500, so that the support block 500 can timely push out the hardware 10 sleeved on the punch.

[0029] In some embodiments, in combination 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.

[0030] On the basis of the above embodiments, 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 a reference, and has a consistent slope with the vertical direction of the bevel punch 200 and the punch fixing block 100. In this way, when the bevel punch 200 obliquely punches the extension portion 11 off the hardware 10, the extension portion 11 will fall into the discharge chute 510.

[0031] On the basis of the above embodiments, 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 cooperating with the guide groove 221a is provided in the discharge chute 510. When the bevel punch 200 obliquely punches the extension portion 11 off 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, so that it leaves a more standard inclined surface on the hardware 10.

[0032] In some embodiments, 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).

[0033] On the basis of the above embodiments, 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 punching space 300, the positioning rods 13 abut against the side wall of the punch fixing block 100 to ensure that the extension portion 11 is located below the impact block 221.

[0034] The details of the exemplary embodiments described above are not limited to the embodiments described above, and the invention may be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive in all respects, and the scope of the invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
