Description

Technical Field

[0001] The utility model relates to the field of hardware processing technology, in particular to a hardware material strip with a pre-cut structure. Background Art

[0002] In order to meet the needs of automated processing, some smaller hardware parts need to be formed through material strips, and then processed together with the material strips. After the processing is completed, the hardware parts can be removed from the material strips. For example, the terminals in the connector are small in size. In order to meet the needs of automated processing, they need to be formed on the material strips, and then automated assembly and splicing processes are carried out. When the assembly is completed and the terminals need to be removed, just shake the terminals or the tail material strips up and down repeatedly.

[0003] In order to facilitate the removal of hardware, a pre-cutting portion is provided at the connection between the hardware and the material strip on the hardware material strip. The existing pre-cutting portion is a "V"-shaped pre-cutting groove. However, in order to prevent the hardware from falling off during the automated processing, the thickness of the pre-cutting groove is generally shallow. However, such a structure not only requires multiple bendings when cutting the hardware, which affects the speed of cutting the hardware, but also forms long strips of metal wire when broken. When the hardware is installed on the outside, the metal wire is easily in contact with external components and conductive, thereby forming a short circuit and causing electrical faults. In severe cases, the entire product may be damaged. Therefore, it is necessary to further improve the existing material strip structure. Utility Model Content

[0004] In view of this, the present invention aims to improve the deficiencies in the prior art, and its main purpose is to provide a hardware material strip with a pre-cut structure, which can effectively solve the problems of the existing hardware material strips such as slow material cutting speed, easy formation of long metal wires, easy formation of short circuits and damage to the entire product.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A hardware material strip with a pre-cutting structure comprises a material strip and hardware, wherein a plurality of hardware connected to the material strip are arranged at intervals on each material strip, and a pre-cutting portion is provided at the connection between the hardware and the material strip, wherein the upper and lower surfaces of the pre-cutting portion are respectively integrally inwardly provided with a "V"-shaped pre-cutting groove, the pre-cutting grooves are symmetrically arranged up and down, and the two ends of each pre-cutting groove respectively penetrate the left and right side walls of the pre-cutting portion; the upper and lower surfaces of the pre-cutting portion are also integrally inwardly provided with a plurality of symmetrically arranged pre-cutting cavities connected to the pre-cutting grooves, the inner bottom surface of the pre-cutting cavity is located on the inner side of the pre-cutting groove, and the plurality of pre-cutting cavities are arranged at intervals along the extension direction of the pre-cutting groove.

[0007] As a preferred embodiment, the bottom of the pre-breaking cavity is a plane, and the front and rear sides of the bottom of the pre-breaking cavity are connected to the outer surface of the pre-breaking portion by obliquely extending connecting surfaces, and the angle between the two connecting surfaces and the outer surface of the pre-breaking portion is greater than the angle between the side wall of the pre-breaking groove and the outer surface of the pre-breaking portion.

[0008] As a preferred solution, the two connecting surfaces are symmetrically arranged on the front and rear sides of the pre-breaking groove.

[0009] As a preferred solution, the upper and lower surfaces of the pre-cutting portion are both provided with two pre-cutting cavities which are arranged in a transverse interval.

[0010] As a preferred solution, the distance between the deepest parts of the two pre-breaking grooves arranged symmetrically up and down is half of the overall thickness of the pre-breaking part, and the distance between the two inner bottom surfaces of the two pre-breaking cavities arranged symmetrically up and down is one third of the overall thickness of the pre-breaking part.

[0011] As a preferred solution, a plurality of positioning holes are provided on the material strip, and the positioning holes are arranged at intervals along the extension direction of the material strip.

[0012] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0013] The upper and lower surfaces of the pre-breaking part are integrally formed with a plurality of pre-breaking cavities that are symmetrically arranged up and down and connected to the pre-breaking grooves. The inner bottom surface of the pre-breaking cavity is located on the inner side of the pre-breaking groove, and the plurality of pre-breaking cavities are arranged at intervals along the extension direction of the pre-breaking groove. When the hardware is unloaded through the deeper pre-breaking cavity, the pre-breaking cavity is easier to break, thereby driving the entire pre-breaking part to break, making the unloading process of the hardware more convenient and the unloading speed is also improved. At the same time, the pre-breaking groove is interrupted by the pre-breaking cavity, so that when the hardware is bent and broken, only point-shaped metal wires will be formed at the pre-breaking place, and no long metal wires will be generated. The point-shaped metal wires are difficult to contact with external components and cause short circuits, thereby avoiding electrical failures and not damaging the entire product due to electrical failures.
