Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, a rough forming tool for producing an elastic pin comprises a main shaft 1; the device also comprises an upper die 2, wherein the upper die 2 is fixed at the lower end of the main shaft 1 through a bolt; in order to collect the pressed and formed workpieces, the press forming machine further comprises a turnover box 3, the turnover box 3 corresponds to the main shaft 1, and a feeding hole 4 is formed in the surface of the turnover box 3, so that the workpieces can fall off directly; still include lower mould 5, lower mould 5 passes through the bolt fastening in turnover case 3 surface, with go up the mould 2 position and correspond.

In order to enable a flat workpiece to be pressed into a U shape at one time, the upper die 2 comprises a fixed end 6 and a forming end 7, the fixed end 6 is connected with the main shaft 1, and the forming end 7 is a long rod with a spherical head and is attached to the bottom of the U-shaped workpiece.

In order to be can directly fall into turnover case 3 after the work piece is press formed, need not staff's operation, lower mould 5 includes bottom plate 8, two arc briquetting 9 and two locating plates 10, have unloading passageway 11 in the middle of the bottom plate 8, with pan feeding hole 4 is linked together, arc briquetting 9 set up in unloading passageway 11 both sides, locating plate 10 is through the bolt fastening in arc briquetting 9 surface. The opposite surfaces of the two arc-shaped pressing blocks 9 are arc-shaped.

The outside of the turnover box 3 is provided with a discharge port 12 to ensure that the finished products are removed in batches when the turnover box 3 is loaded more or less.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
