Description

Technical Field

[0001] The utility model relates to the field of material connection structures, in particular to a one-line positioning punch rod material connection structure. Background Art

[0002] The one-shaped positioning punch is used to position and fix the cold-forged blank when it is moving to the next station, so as to prevent the blank from rotating when it is ejected. The one-shaped positioning punch of the next station first positions the blank so that it can be smoothly fed into the die without rotating. However, for cold-forged blanks with external drive for automotive external thread fasteners, the external drive may be rubbed during the cold forging process, making the external drive function unusable and causing the product to be scrapped. For this reason, we have proposed a one-shaped positioning punch material receiving structure. Utility Model Content

[0003] 1. Technical issues to be solved

[0005] (II) Technical solution

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a straight-line positioning punch connecting material structure, comprising a main mold and a directional main mold pad connected together, the directional main mold pad and the main mold are provided with transversely penetrating holes, the hole of the directional main mold pad is inserted into the inside of the main mold push rod, and a lower punch is provided at one end of the main mold push rod located inside the hole, and the lower punch has a straight-line shape, and the inside of the hole of the main mold is used to insert the preceding blank.

[0007] Preferably, a positioning hole is provided on one side of the main mold and the directional main mold cushion block which are close to each other, and a positioning pin is provided inside the positioning hole.

[0008] Preferably, a threaded hole connected to the inner hole of the main mold cushion block is provided at the end of the main mold cushion block, and a ball screw is connected to the inner thread of the threaded hole.

[0009] Preferably, a 120-degree notch is provided at the front end of the internal hole of the main mold.

[0010] (III) Beneficial effects

[0011] Compared with the prior art, the utility model provides a one-line positioning punch rod material receiving structure, which has the following beneficial effects:

[0012] 1. The one-shaped positioning punch receiving structure can first position and fix the blank through the one-shaped lower punch when it moves to the next station, so as to prevent the blank from rotating when it is ejected. The one-shaped positioning lower punch of the next station can first position the blank so that it can enter the die smoothly without rotating, so as to solve the problem of drive edge scraping of external drive cold heading blank during continuous operation, which makes the external drive unusable and the product scrapped.
