Description

Technical Field

[0001] The utility model relates to the technical field of steel wire cutting, in particular to a steel wire segmentation die. Background Art

[0002] At present, the production of a certain product requires a steel wire with a length of 3mm and an outer diameter of 2.5mm as a component. The steel wire with an outer diameter of 2.5mm is used for cutting, and the cross-section surface is required to be flat. The existing ordinary steel wire cutting tool uses a flat blade to cut the steel wire. The cross-section of the steel wire will form a shear edge, which cannot achieve the effect of a flat cross-section. Subsequent trimming process is required to process the cross-section, affecting production efficiency. Utility Model Content

[0003] Based on this, the purpose of the present invention is to provide a steel wire segmentation die to solve the technical problems raised in the above background.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a steel wire segmentation mold, comprising a handle, a cutting knife mounted on the handle, a base plate located below the handle, and a fixed block mounted on the base plate, wherein a cutting lower die and a cutting length adjustment block are mounted on the fixed block, the cutting length adjustment block is located on one side of the cutting lower die, the cutting lower die is located directly below the cutting knife, the cutting knife is provided with an arc-shaped cutting edge, and the cutting lower die is provided with a circular cutting hole.

[0005] Furthermore, the tool handle is fixedly mounted on the punch press slider.

[0006] Furthermore, the bottom plate is fixedly mounted on the work surface of the punch press.

[0007] The utility model cooperates with the circular cutting edge on the cutting knife and the circular cutting hole on the cutting lower die. The circular cutting edge plays a shaping role on the cut end face during punching and cutting. The steel wire section and cross-section are flattened in one punching process without shearing edge and without the need for subsequent cross-section trimming process.

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0013] The following describes an embodiment of the present invention based on its overall structure.

[0014] like Figures 1-4 As shown, the utility model includes a shank 1, a cutting knife 2, a steel wire 3, a cutting lower die 4, a cut length adjusting block 5, a fixing block 6, and a base plate 7. The steel wire is cut on a punch press. The base plate 7 is bolted to the work surface of the punch press, the bottom die fixing block 6 is bolted to the base plate 7, the cutting lower die 4 is bolted to the bottom die fixing block 6, the cut length adjusting block 5 is bolted to the bottom die fixing block 6 and the mounting position can be adjusted. The shank 1 is bolted to the punch slide, the cutting knife 2 is bolted to the shank 1, the cutting lower die 4 is located directly below the cutting knife 2, the cutting knife is provided with an arc-shaped cutting edge 8, and the cutting lower die 4 is provided with a circular cutting hole 9.

[0015] When the utility model cuts the steel wire into sections, the operator feeds the steel wire from the cutting hole of the cutting lower die 4, and lengthens the steel wire through the cutting length adjusting block 5, starts the punch switch, and the punch slider drives the knife handle 1 and the cutting knife 2 assembly to punch and cut the steel wire into sections. The cut steel wire sections fall out from under the bottom plate 7 and fall into the turnover box. The punch slider drives the knife handle 1 and the cutting knife 2 assembly to lift and reset, and the steel wire continues to be fed, completing the steel wire punching and cutting process. It is achieved that the steel wire can be lengthened and cut in one punching process on the punch, and the cross-section can be flattened. The operation is simple, the die installation and debugging are convenient and fast, and the precision and efficiency are high.

[0016] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
