Problems solved by technology
Since the outlines of the chain pieces 92 vary in various ways, they cannot fit together when they are arranged, so there will be gaps 911 between the chain pieces 92 in each horizontal row, and the chain pieces 92 will be punched out. Finally, it remains and becomes waste, resulting in a waste of resources
In addition, since punching is to make the chain piece 92 directly separate from the plate 91, the general forming method of the chain piece 92 still cannot be modified in detail.
[0003] It can be seen that the above-mentioned existing chains obviously still have inconvenience and defects in method and use, and need to be further improved urgently.

Embodiment Construction
[0017] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation methods, methods, steps, Features and their functions are described in detail below.
[0018] refer to figure 2 , 3 , a preferred embodiment of the chain piece forming method of the chain of the present invention can form several chain pieces 1, and includes the following steps:
[0019] Go to step 70: Prepare an elongated substrate 2 made of metal material. The substrate 2 of this embodiment is a disk element with a circular cross section, and the diameter of the cross section is 22 centimeters (mm).
[0020] Go to step 71: reduce the size of the cross-section of the substrate 2 by drawing a wire. In this preferred embodiment, after the base material 2 is drawn, the diameter of the cross section of the base material 2 is 20.3 ...

Abstract
The invention relates to a chain sheet forming method of a chain. A plurality of chain sheets can be formed, and the method comprises the steps that: firstly, a longitudinal extending processing substrate made of metal materials is molded in a line pulling mode, and a longitudinal extending chain sheet substrate with the cross section in the chain sheet shape is formed; then, the chain sheet substrate is forged and cut for producing a plurality of chain sheet bodies; next, the chain sheet bodies are forged and punched for being regulated into preset shapes, and the thickness of the chain sheet bodies are identical; and finally, the chain sheet bodies are forged and punched, in addition, two penetrated through holes are generated on each chain sheet body at intervals, and the chain sheets are formed. The chain sheet forming method has the advantages that the cross section of the substrate can correspond to the outline of the chain sheets in a line pulling mode, the chain sheet bodies are generated in a forging and cutting mode, and the chain sheet is generated through processing, so the goals of reducing waste materials and avoiding resource waste are reached.
Description
technical field [0001] The invention relates to a chain, in particular to a chain formed by a chain piece forming method. Background technique [0002] figure 1 It is the chain piece 92 of the chain that can be punched continuously disclosed in Patent Publication No. 370904, utilizes a plate 91, and forms several chain pieces 92 directly with the mode of punching. During molding, the chain pieces 92 are closely side by side side by side, and each row is spaced up and down from each other. Since the outlines of the chain pieces 92 vary in various ways, they cannot fit together when they are arranged, so there will be a gap 911 between the chain pieces 92 in each horizontal row, and the chain pieces 92 will be punched out. Finally, it remains and becomes waste, resulting in a waste of resources. In addition, since the die-cutting is to make the chain piece 92 directly separate from the board 91 , the general forming method of the chain piece 92 still cannot be modified in d...
