Description

Manufacture of handle horseshoes. The production of clip-on handle horseshoes was previously only left to the farrier, who welded a steel plate onto the toe part of a factory-made or hand-made horseshoe and then provided it with a tapered hole that was used to hold the clip-on handle. This work was very time consuming and costly. It also had to be carried out very carefully by a trained blacksmith, as the harder steel plate easily settled the iron when it was welded on, so that the horseshoe very often broke off next to the welded plate during use. The main condition but that the plug handle with its tapered pin completely stuck in a steel jacket, was also hereby not reached, since the steel plate is only 1/3 or more to 1 /, of the journal length constituted of the plug handle. There are now factory-made horseshoes with reinforcements rolled onto the toe part, which therefore only need to be punched. However, these irons have not proven themselves because the reinforcement is made of the same material as the horseshoe itself and is therefore too soft. As a result, the plug-in handles will very quickly become loose and fall out.

All of these shortcomings are eliminated by the method of the invention contained therein consists of a steel core that runs through the entire iron strength of the toe part of a Horseshoe goes, pressed into this, punched and thereby welded to this. Fig. I shows a finished horseshoe seen from the ground surface, Fig. 2 shows a Section along the line A-B, Fig. 3 a section along the line C-D, Fig. Q. a Section through the toe part with a flared hole and a sharp plug-in handle, Fig.5 shows a section through the toe part of a horseshoe, Fig. 6 the one to be pressed in Steel core, Fig. 7, the pressed-in steel core with a raised elevation on the Bottom surface of the horseshoe, Fig. 8 is a top view. Fig. 9 is a side view, Fig. io a front view of the lower die into which the horseshoe is inserted, Fig. Ii, finally, the overall arrangement of the tool, partially drawn in section, with intermediate plate and guide cartridge for inserting the steel core and top plate with pressure stamp.

The working process is described as follows: The still red-hot horseshoe that has been removed from the machine is placed in the lower die with the wing facing up (Fig. 5) (Fig. 8). The toe part of the horseshoe is enclosed here by exchangeable fittings g, h. Underneath these fitting pieces a replaceable die i provided with a recess is let in, which is held down by the fitting pieces g, h. The steel core shown in Fig. 6, which has the shape of a flat-rolled round bar, is now inserted into the guide cartridge k (Fig. Ii), which is interchangeably embedded in the intermediate plate l and connected to the press carriage by four suspension rods n. The plate i is guided by four guide bolts m, which are screwed into the lower die.

When the press is triggered, plate 1 first lowers onto the one in the Horseshoes lying on the die, and after lowering the press slide, it presses In the upper plate, the pressure stamp p fastened the steel core c through the guide cartridge k into the toe part of the glowing horseshoe, as shown in Figure 7. That Metal displaced by the steel core fills the recess during this process in the die i and forms one of the shapes on the bottom surface of the horseshoe Recess corresponding increase b, which is essential for strengthening the horseshoe contributes to the toe part.

After the press slide has gone up, lift the lower ends the suspension rods, c located bundles y the intermediate plate 1 from the lower Die again, at the same time the ejector pin located in the lower die is also removed is actuated in a known manner, which when the carriage reaches its uppermost position lifts the horseshoe out of the die so that it can be easily removed can.

Now the horseshoe on the toe part is brought to the heat of sweat again and then fed to a second press which, with the exception of the intermediate plate owns exactly the same tool. There is a punch in the top plate, which serves to perforate the steel core in the middle. With this pressure the steel core is driven apart by the punch under welding heat, so that it is welded to the iron surrounding it and the steel core is stuck in the iron is included (Fig. z and 3).

The horseshoe is now ready for the farrier to use. He has only necessary when adjusting the horseshoe to the hoof, what the iron for anyway must be heated to drive a mandrel into the existing hole from the bottom surface, to make it capable of receiving the plug-in handle c.

By the fact that the steel core c through the whole thickness of the horseshoe on the toe part, a secure fit of the driven plug-in handle is guaranteed.
