Description

Technical Field

[0001] The invention relates to the technical field of hardware stamping production, in particular to a high-strength hardware forming die and a forming method. Background Art

[0002] Metal stamping parts are widely used in various fields of our lives. Stamping parts use mold pressure to deform the sheet material to obtain parts with certain shapes, sizes and performances. The plastic processing technology is called stamping, and the parts obtained after stamping are called stamping parts. The production of metal stamping is completed by metal stamping workers, and metal stamping dies are produced by machine tools or mold factories. Some machine tools and mold factories also produce stamping parts. For example, metal gaskets and various fasteners commonly used in the machinery manufacturing process can be processed by metal stamping.

[0003] The existing metal stamping equipment has the following problems: on the one hand, the opening and closing of the mold and the ejection of the material both require the cooperation of independent actuators, which will undoubtedly reduce the production efficiency for hardware that needs to be mass-produced. On the other hand, the metal stamping process uses the stamping mold to achieve the stamping work, so the stamping mold determines the final product of the metal stamping. When the mold needs to be replaced during metal stamping, it is a complicated process that requires shutdown and various disassembly to complete the mold replacement. The shutdown for mold changing is an important reason for the decline in production capacity in the metal stamping process, and the existing technology is not easy to solve such problems.

Secondly, when the upper sliding pin 504 breaks away from the other side inclined surface of the "V"-shaped cam groove of the upper groove cam 3, the upper sliding pin 504 drives the punch body 506 to lift up through the sliding rod 503 to achieve mold separation with the die body 407. Finally, the lower sliding pin 410 slides through the circumferential cam groove of the lower groove cam 1, and when it passes through the "V"-shaped cam groove with the notch facing downward in the lower groove cam 1, the lower sliding pin 410 drives the ejector rod 409 to lift up in the through hole in the middle of the die body 407, and then lifts up and discharges the molded material retained in the die cavity of the die body 407 after mold separation.

A high-strength hardware forming die according to claim 7, characterized in that: A mold changing assembly (12) is arranged inside the sleeve (10), and the mold changing assembly (12) comprises an electric cylinder (1201), a mounting plate (1202) and a connecting rod (1203). The electric cylinder (1201) is bolted to the top of the sleeve (10), and the output end of the electric cylinder (1201) is fixedly connected to the mounting plate (1202), and the connecting rod (1203) is rotatably connected to both sides of the recess of the mounting plate (1202).

9. A high-strength hardware forming die according to claim 8, characterized in that: The mold changing assembly (12) also includes a telescopic plate (1204), an insert rod (1205) and a fixed plate (1206); the end of the connecting rod (1203) facing away from the mounting plate (1202) is rotatably connected to the telescopic plate (1204), and the insert rods (1205) are fixedly connected to the front sides of the telescopic plate (1204); the insert rods (1205) correspond to the positions of the insert holes (408) provided on the concave mold body (407) and the convex mold body (506), and the insert rods (1205) are slidably installed inside the through holes on both sides of the fixed plate (1206), and the fixed plate (1206) is welded and fixed to the side wall of the sleeve (10).

10. A high-strength hardware forming die according to any one of claims 1 to 9, characterized in that: The molding method comprises the following steps: Step 1: The upper sliding pin (504) fixed to the top of the sliding rod (503) slides in the circumferential cam groove of the upper groove cam (3). When the upper sliding pin (504) enters the inclined surface of the "V"-shaped cam groove with the notch facing upward, the upper sliding pin (504) presses down the convex mold body (506) through the sliding rod (503) to achieve mold closing with the concave mold body (407), thereby stamping and forming the hardware in the mold cavity of the concave mold body (407); Step 2: When the upper sliding pin (504) is separated from the other side inclined surface of the "V"-shaped cam groove of the upper groove cam (3), the upper sliding pin (504) drives the male mold body (506) to be lifted through the sliding rod (503) to achieve mold separation with the female mold body (407); Step 3: The lower sliding pin (410) slides through the circumferential cam groove of the lower groove cam (1). When passing through the "V"-shaped cam groove with the notch facing downward of the lower groove cam (1), the lower sliding pin (410) drives the ejector rod (409) to lift up in the through hole in the middle of the die body (407), thereby lifting and discharging the molding material retained in the die cavity of the die body (407) after mold separation.
