Description

Technical Field

[0001] This utility model relates to the field of stamping dies for the production of nuts, and more specifically, to a stamping die for the production of nuts. Background Technology

[0002] A nut is a common name for a bolt, a part with an internally threaded hole, usually used in conjunction with the external threads of a bolt or screw to achieve a fastening connection of mechanical parts by tightening. The standard term should be "nut," while "nut" is more commonly used in informal settings, primarily serving a fastening and connecting function, and is widely used in machinery manufacturing, construction, equipment installation, and other fields. Some specially designed nuts (such as lock nuts) can also prevent loosening caused by vibration. Stamping refers to a processing method that uses a press and dies to apply external force to sheet metal, strip, pipe, and profiles, causing plastic deformation or separation to obtain workpieces of the desired shape and size. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. Stamping technology is widely used in modern times; however, existing stamping processes often have the following shortcomings in the production of electrical nuts: axial vibration often occurs during the stamping process of electrical nuts, easily leading to high wear and tear on stamped electrical nut products and affecting production efficiency.

[0003] In existing technologies, such as the nut stamping process disclosed in patent announcement CN213409983U, an electrical nut stamping forming device includes a base and an upper plate mounted on the base. A hydraulic telescopic cylinder is fixedly mounted on the upper plate via connecting fasteners. A connecting rod is fixedly connected between the base and the upper plate. A shelf is provided between the base and the upper plate. A guide groove is provided on the base, and a baffle is slidably connected within the guide groove. A side support rod is driven between the bottom end of the baffle and the bottom end of the base via a rotating shaft. A limiting slider is fixedly connected to the top end of the baffle. A limiting groove is provided at the bottom end of the shelf, and the limiting groove is slidably connected to the limiting slider. In this invention, a linkage rotation transmission mechanism is used, making the downward displacement process of the shelf more stable and effective. A spiral pressing installation structure is used to facilitate the quick and stable replacement of the extrusion cutter.

[0004] In the aforementioned patent, after the nut is formed and stamped, the nut workpiece can be stuck in the mold groove and cannot be quickly unloaded. In the existing nut stamping process, the workpiece is ejected from the bottom to the top, which requires a separate drive ejection mechanism, which is costly and inconvenient to use. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a stamping die for nut production. The die is formed directly by a nut molding stamping head. After forming, since the nut molding stamping head is made of magnetic material, it can directly attract and pull out the formed nut after stamping. When it rises, the stripper rod can be placed against the top seat of the die, which can drive the stripper strip to push the nut down. The stripper strip is convenient to remove material, does not require additional driving equipment, and has low cost.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A stamping die for producing nuts includes a stamping base, characterized in that: a support rod is fixedly connected to the upper surface of the stamping base, a die top seat is fixedly connected to the upper surface of the support rod, a die holder is provided on the upper surface of the stamping base, a nut die cavity is provided on the surface of the die holder, a hydraulic cylinder is fixedly connected to the upper surface of the die top seat, a nut die pressing head is fixedly connected to the end face of the hydraulic rod of the hydraulic cylinder, and the outer surface of the nut die pressing head presses against the inner surface of the nut die cavity. A stripper bar is slidably connected to the lower end of the stamping head. A stripper rod is fixedly connected to the upper surface of the stripper bar. A protrusion is provided on the surface of the stripper rod, and a spring is sleeved on the outer surface of the stripper rod. The nut is directly stamped by the nut molding stamping head. After forming, since the nut molding stamping head is made of magnetic material, it can directly attract and pull out the formed nut after stamping. When it rises, the stripper rod can push against the top seat of the mold, which can drive the stripper bar to push the nut down. The stripping is convenient, does not require additional driving equipment, and has low cost.

[0008] Furthermore, the nut molding stamping head is made of magnetic material, and the stripper bar is made of stainless steel.

[0009] Furthermore, the stripping rod is distributed on the upper surfaces of the left and right sides of the stripping bar, and the surface of the nut molding stamping head is provided with an insertion hole, and the outer surface of the stripping rod is slidably connected to the inner surface of the insertion hole.

[0010] Furthermore, support seats are provided on both sides of the nut molding stamping head.

[0011] Furthermore, the outer surface of the support base is provided with a positioning notch, and the inner surface of the positioning notch of the support base slides against the outer surface of the support rod.

[0012] Furthermore, the lower end surface of the nut molding stamping head is provided with a positioning groove, and the outer surface of its stripper bar is slidably connected to the inner surface of the positioning groove.

[0013] Furthermore, the outer surface of the nut molding stamping head is slidably engaged with the inner surface of the nut cavity of the mold base.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) The nut is formed by direct stamping with a nut molding stamping head. After forming, since the nut molding stamping head is made of magnetic material, it can directly attract and pull out the formed nut after stamping. When it rises, the stripping rod can be pushed against the top seat of the mold, which can drive the stripping strip to push the nut down. It is convenient to strip the material, does not require additional driving equipment, and has low cost. Attached Figure Description
