Problems solved by technology

The former still needs to be assembled and combined to complete the fixture structure, so the defect of inconvenient and time-consuming assembly has not been effectively improved, while the latter has no assembly action, but the structural strength of the fixture is poor, and it is difficult to have wide applicability

Embodiment Construction

[0026] see figure 1 As shown, the present invention relates to a manufacturing method of a metal simple clip, which includes the following processes in sequence: taking the substrate (10), fixing the hole (11), trimming the edge (12), forming the unit piece (13), folding the lip (14), warping (15), molding elastic portion (16), bending (17), closing (18) and truncation (19) etc. a series of connected processes.

[0027] see figure 1 , 2 As shown, the base plate (21) is a metal plate, and for subsequent continuous processing operations, the metal plate has a considerable length, and can be a coiled metal sheet if necessary.

[0028] Since continuous processing will be carried out on the substrate (21), in order to facilitate the smooth automatic advancement of the substrate, a plurality of central holes (22) arranged in a straight line are provided at the center of the substrate (21). In order to facilitate the cutting action during subsequent processing, several cutting hol...

Abstract

The present invention relates to a production method of simple metal clip, and is characterized by using a base plate and adopting the following steps: defining hole, cutting edge, forming unit sheet, folding lip, warping, forming elastic portion, bending, closing-in and cutting so as to obtain the invented integrally-formed simple clip. It can reduce working time, and can raise production efficiency.

Description

【Technical field】 [0001] The invention relates to a manufacturing method of a metal simple clip. 【Background technique】 [0002] A general metal clamp (sub) is mainly composed of a first clip, a second clip and a spring. Wherein the first clamping piece and the second clamping piece are pivotally connected, and the spring assembly is arranged at the pivotal joint position, and the two ends of the spring respectively abut against the first clamping piece and the second clamping piece. Although the first clamping piece and the second clamping piece can provide a clamping function, it is obviously quite inconvenient and time-consuming to assemble. [0003] As for clamps made of plastic materials, some have a first clamping piece and a second clamping piece like the above-mentioned metal clamping piece, and a spring is arranged between the first clamping piece and the second clamping piece, while some are Made into one piece. The former still needs to be assembled and combine...
