Anyone that runs the excellent machines will be winner in the vehement competition with the successive updated technology. It is such a good example to manage 2D3B-XP2 multi-station heading machine to manufacture flowering hobnails. The shoes sold on market are one of daily necessities. With 1,3 billion population, China is a great country for the largest amount of products to manufacture and export. Various shoes are the most common ones that people like to wear and also the quantity and change frequency of woman shoes exceed men's. However, people rarely know that flowering hobnails connecting the bottom of high-heel shoe belong to fasteners. Requiring high technology and quality, this kind of hobnails is in large demand.

There are two modes of manufacture in current technologies: one is using ordinary double heading machine to produce blank firstly. And flowering forming process is made on punch machine, however, it is inefficient with complicated procedure and the disability of automatization, meanwhile requiring more machines and workers. In addition lacking of stations for the heading machine, the dies will bear larger counterforce and result in large abrasion of dies and so that the production cost is very high. At that time, the price of this kind of hobnail was fairly high, manufacturers could benefit a lot. When multi-station heading machine is produced, this technology can't exist any more and tends to fall into disuse. Besides, with the improvement of technology and more vehemence of competition, some manufacturers introduce special multi-station machine (such as 2 die 4 blow machine) to produce, automatize forming production of this kind of hobnails, enhance the production efficiency largely, save the investment to punch and increase the competitive power of products comparatively. But still some equipment needs large investment (just one machine needs more than RMB0.2 million) and high operation level, die expenses and wage of workers are high. Are there better machine and technology to produce this kind of hobnails? People are seeking and searching.

Not very long ago, we found an enterprise using the patented 2D3B- XP2 cold heading machine of Shixi Enterprise (international) Organization to produce this kind of hobnail. They happily told us that the patent worked well. The machine adopts non-clamp feeding technology and takes out the complex gears and cam operation clamp system. Although punch is less than those of 2 die 4 blow machine, it still has the capability of 2 die 4 blow machine, no other than easier structure of machine but stronger function. The requirement of adjusting and testing as well as operation level is lower, production speed is higher, die expense is decreased and efficiency is higher. Furthermore, price of the machine is much lower than that of import, its products have more powerful competitive capacity, as a result the machine brings more profits to hobnail manufacturers.

The followings are cold heading processes of hobnail and figures
1. The cutter cuts off the wire rod and brings it into the 1st die, see figure 1 for the form.
2. The first punch obtrudes a hole to one bottom of blank and make the other bottom shrink, see figure 2.
3. The second punch brings the blank with hole from 1st die to 2nd die, strikes out the form of figure
4. The third punch makes the hole broken as flowering form, see figure 4.
