Embodiment 1

[0041] Embodiment 1: a kind of thread rolling board, such as image 3 As shown, including the base plate 1, the top of the base plate 1 is provided with a thread rolling surface 2, and the thread rolling surface 2 is provided with a thread, and the height of the thread from the feed end to the discharge end first gradually increases and then remains straight.

[0042] The feeding end of thread rolling surface 2 ( image 3 The right side of the center is the feed end, and the left side is the discharge end) is provided with a pressing plane 7, the thread on the thread rolling surface 2 is connected with the pressing plane 7, and the length of the pressing plane 7 is 1 / of the length of the bottom plate 1 10-1 / 4.

[0043] in. Anti-slip grooves 6 intersecting the feeding direction are provided on the pressing plane 7 and the feeding end of the thread rolling surface 2 .

[0044] Two pressing knives 3 are arranged on the top of the bottom plate 1, and the two pressing knives 3 ...

Embodiment 2

[0048] Embodiment 2: a kind of silk rolling process, comprises the following steps:

[0049] S1, material selection, raw materials are selected, the diameter of the threaded column processing section of the raw material is greater than the diameter of the finished threaded column, and the length of the threaded column of the raw material is less than the length of the finished threaded column;

[0050] S2, the thread rolling plate is installed, the thread rolling plate in the installation embodiment 1 is installed as follows Figure 5 As shown, the distance between the two pressing planes 7 on the two thread rolling boards is smaller than the diameter of the threaded column processing section of the raw material.

[0051]Working principle: The raw material enters the two thread rolling boards for thread rolling. Initially, the thread column processing section is firstly located between the pressing planes 7 of the two thread rolling boards, and is crushed and lengthened in the...

Abstract

The invention discloses a thread rolling die and a thread rolling process using the thread rolling die. The thread rolling die comprises a bottom plate, a thread rolling face is arranged at the top ofthe bottom plate, tooth patterns are arranged on the thread rolling face, two pressing cutters arranged on the two sides of the thread rolling face in parallel are arranged at the top of the bottom plate, the cross sections of the cutting edges of the two pressing cutters are gradually increased from the feeding ends to the discharging ends of the pressing cutters, and the cutting edges, facing the washout thread machining side of the bottom plate, of the two pressing cutters are obliquely arranged. During thread rolling, a corresponding annular groove is machined in the bolt raw material through the pressing cutters, one-time machining is achieved, and efficiency is high. According to the thread rolling die, the annular groove is machined in a cold pressing mode, redundant materials in the position of the annular groove in the raw material are guided to move towards the end of the threaded column through inclined arrangement of the cutting edge, the redundant materials in the annulargroove are finally pressed to the end of the threaded column, the threaded column is lengthened instead of being cut off, and materials are saved.

Description

technical field [0001] The invention relates to the technical field of thread processing, in particular to a thread rolling board and a thread rolling process using the thread rolling board. Background technique [0002] The thread rolling board is the most commonly used thread tool for processing screws and bolts in the standard fastener industry. It is divided into two pieces, one long and one short, with tooth patterns on it. It has the advantages of high efficiency, low processing cost, high thread precision and strength, and good surface quality, and has been widely used. [0003] Existing thread rolling boards are mostly only suitable for processing bolts with threads, and cannot process non-standard bolts and special bolts with structures such as annular grooves. like figure 2 The bolt shown has grooves at both ends of the threads. The raw material used is optical shaft material. In order to produce the above-mentioned bolts, the existing production method is to fi...
