Abstract

The invention relates to a double-faced sloping grain thread rolling die which comprises a base plate (1). The top and the bottom of the base plate (1) are respectively provided with a thread rolling face (2). The two thread rolling faces (2) are respectively provided with at least one thread (3) which is a sloping grain thread. A scrap groove (4) is formed between two adjacent threads (3). Scrap grooves are formed in the double-face sloping grain thread rolling die and can be used for collecting surplus scraps produced in the machining process so as to ensure the quality of bolts, and the two thread rolling faces can be used in turn, so that the service life of the thread rolling die is prolonged.

Description

(1) Technical field [0001] The invention relates to a double-sided twill thread rubbing board. (2) Background technology [0002] The thread rolling board is a tool that uses metal plastic deformation to roll out threads on the thread rolling machine. It is suitable for processing ordinary bolts and high-strength bolts. Thread rubbing boards include twill thread rubbing boards. During the processing of bolts, excess waste will be generated on the thread rolling boards, which affects the processing effect of bolts to a certain extent, and the quality of produced bolts is not good; in addition, the current rubbing boards There is only one side of the thread rolling surface on the thread plate, and when the thread rolling surface is damaged, the whole thread rolling plate must be discarded, which will cause waste. (3) Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a double-sided twill thread rubbing b...
