Problems solved by technology

The thread rolling board includes straight grain thread rolling board and serrated thread rolling board. During the processing of bolts, excess waste will be generated on the thread rolling board, which affects the processing effect of bolts to a certain extent, and the quality of the produced bolts Not good; in addition, the current thread rolling board has only one thread rolling surface, and can only process one type of bolt, and when the thread rolling surface is damaged, the entire thread rolling plate has to be discarded, which will cause waste

Abstract

The invention relates to a thread rolling plate with two-sided threads. The thread rolling plate comprises a bottom plate (1), wherein the top and the bottom of the bottom plate (1) are provided with thread rolling surfaces (2); at least one thread I (3) and at least one thread II (4) are respectively arranged on the two thread rolling surfaces (2); the threads I (3) are straight threads; the threads II (4) are sawtooth threads; attle slots (5) are formed between every two adjacent threads I (3) as well as between every two adjacent threads II (4). The thread rolling plate with the two-sided threads is provided with the attle slots, and can be used for collecting residual attles generated in a processing process and ensuring the bolt quality; the two thread rolling surfaces can be used alternately, so that the service life of the thread rolling plate is prolonged.

Description

(1) Technical field [0001] The invention relates to a thread rolling board with double-sided thread. (2) Background technology [0002] The thread rolling board is a tool that uses metal plastic deformation to roll out the thread on the thread rolling machine. It is suitable for processing ordinary bolts and high-strength bolts. The thread rolling board includes straight grain thread rolling board and serrated thread rolling board. During the processing of bolts, excess waste will be generated on the thread rolling board, which affects the processing effect of bolts to a certain extent, and the quality of the produced bolts Not good; in addition, the current thread rolling board has only one side of the thread rolling surface, and can only process one type of bolt, 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 purpose of the present invention is to overco...
