Problems solved by technology

However, the existing two-row continuous stretching production method cannot well control the stretching process of the metal sheet, which will cause unbalanced stretching or shearing of the metal sheet, causing the stretched material to break, and the material to be stretched during stretching. The width will shrink, and the distance will change after stretching; in addition, there will be material grabbing when the left and right sides are stretched, poor fluidity of the metal sheet, and the stretched button will burst during the stretching process, etc.
The above-mentioned defects reduce the yield of products and cause waste of raw materials
Moreover, there is still the problem of low production capacity in double row continuous stretching production

Embodiment 1

[0045] Embodiment 1, as shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4:

[0046] In this embodiment, what needs to be stretched is a metal button connector called button bead B, as shown in Figure 4, which includes the following process steps:

[0047] A. Positioning hole on stamping edge:

[0048] In this embodiment, the width of one beer and five outs is used to select the metal sheet. First, according to the size of the buckle connector to be stretched, use the punching pins 111, 33 on the mold to punch out the edge positioning holes 1, 33 on both sides of the metal sheet. 3. The positioning hole of the fork needle in this step is used to fix the material belt stroke, ensure the accuracy of material belt feeding, ensure the stability of product quality and the service life of the production mold, and can also prevent the hole from being stretched and grab the material. Process protection The width of the material tape will not shrink during stretching, ensuring that the distance...

Embodiment 2

[0061] Embodiment 2, as shown in Fig. 5, Fig. 6, Fig. 7:

[0062]In this embodiment, the stretched buckle connector is meson C, and what is used is also a metal sheet with five outs. In the embodiment, the punching edge positioning hole, the punching fastener positioning hole, the center cutting knife, The splitting of the trimmings, the forming of the cups and the blanking of the trimmings are the same as those in Example 1. The difference is the step-by-step stretching process. In this embodiment, according to the final forming requirements of the meson, firstly, it will go through ordinary stretching of the edge plate and three rows of stamping columns, and then divide it into eight equal parts with a chopping knife. , and then carry out three separate stretches, and through the reverse position, punching, reverse eight-petal forming, eight-petal forming and then enter the drawing cup forming process to form the finished product of the meson. The reverse position, punching...

Embodiment 3

[0063] Embodiment 3, as shown in Fig. 8, Fig. 9, Fig. 10:

[0064] The buckle connectors stretched in this embodiment are corns D, and the metal plates with one beer and five outs are also used as raw materials. Processes such as material, flash conjoined notch splitting, cup drawing molding and notch blanking are the same as in embodiment 1.

[0065] The difference in this embodiment is that five-stage stretching is used, and after step-by-step stretching, punching is performed again, and then R-stretching is used to form the final corn product. Step-by-step stretching and punching as well as the R-stretch forming technology can all adopt the process methods in the prior art.

Abstract

The invention relates to a process method making use of a metal plate to extend a fastener connecting part, belonging to the metal extending technology field. The invention is characterized in that the method includes the following process steps: edge positioning holes are punched: a punching needle is used for punching edge positioning holes on the two sides of a metal plate; fastener positioning holes are punched: the punching needle is adopted to punch a plurality of fastener positioning holes at the two sides of the metal plate, and the distribution of the fastener positioning holes appear as a regular polygon and form a basic figure for the extending of fastener connecting parts crossed and staggered; material is distributed by a central cutting die: a cutting die is adopted to cut out a material distribution gap between two fastener positioning holes, and the distribution gap is parallel to the end of the metal plate and the distribution gap is cut out between two neighboring fastener positioning holes; material is distributed by flowed head integrated with pruning wound: a punching column is adopted to carry out flowed head and pruning wound material distribution between two distribution gaps to pull out a material distribution line; the stretching is carried out step by step; cup stretching forming: after the stretching is carried out step by step, the other edge-pressing plate provided with a punching hole is adopted for the stretching forming in the end, and then blanking are conducted by the pruning wound.

Description

Technical field: [0001] The invention relates to a process method for stretching buckle connectors by using metal sheet materials, which belongs to the technical field of metal button products using a stretching method. Background technique: [0002] About 95% of the current button manufacturing process is designed for single-row continuous stretching production, and 5% is designed for double-row continuous stretching production. The single-row continuous stretching production method is a universal production process, which can only complete the production and molding of single-row buttons each time, and its production efficiency is low, and the quality of the formed buttons cannot be guaranteed. The existing double-row continuous stretching production method is an improved production process, which can complete the stretching of two rows of metal buttons through one process, which improves the production efficiency. However, the existing two-row continuous stretching produ...
