Thread roller device capable of avoiding thread lost caused by overhigh cutting speed

Abstract

The invention relates to the technical field of thread rollers, and discloses a thread roller device capable of avoiding thread lost caused by overhigh cutting speed. The thread roller device comprises a knob and a conveying mechanism, wherein the bottom of the knob is fixedly connected with a threaded rod, the outer side of the threaded rod is in threaded connection with a sliding block, and theright side of the sliding block is fixedly connected with a baffle. According to the thread roller device capable of avoiding thread lost caused by the overhigh cutting speed, the knob is rotated, a circular ring moves up and down between a first conical shaft and a second conical shaft at the moment, the rotating speed between the second conical shaft and the first conical shaft is further changed, and then the rotating speed of a thread rolling cutter driven by a rotating shaft is also changed at the moment, so that the effect that the cutting speed can be adjusted according to different metal materials is achieved. When a rotary disc is rotated, a first connecting block and a second connecting block can drive a movable plate to periodically move up and down, and a stop lever can periodically release workpieces to be machined on the conveying mechanism, so that the effect of automatic feeding is achieved.

Description

technical field [0001] The invention relates to the technical field of thread rolling machines, in particular to a thread rolling machine device for avoiding tooth loss caused by excessive cutting speed. Background technique [0002] The thread rolling machine is a multi-functional cold extrusion forming machine tool. The thread rolling machine can process the thread, straight grain and oblique grain rolling of the workpiece in the cold state within its rolling pressure range. Straight teeth, helical teeth and helical spline teeth rolling; straightening, reducing, rolling and various forming rolling. [0003] The existing thread rolling machine usually needs to manually insert the metal rod between the two thread rolling wheels. This feeding method is not only inefficient, but also has certain safety hazards, and the existing thread rolling machine has a thread hobbing knife The rotation speed cannot be adjusted. When targeting metals with different hardness, too fast rotat...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a thread rolling machine device that avoids tooth loss caused by excessive cutting speed, which has the advantages of automatic feeding and adjustment of cutting speed according to different metal materials, and solves the problem of existing thread rolling machine. The machine usually needs to manually insert the metal rod between the two thread rolling wheels. This feeding method is not only inefficient, but also has certain safety hazards. In addition, the speed of the thread hobbing knife of the existing thread rolling machine cannot be adjusted. When targeting metals with different hardness, too fast rotation speed may cause tooth loss at the end of the metal rod, which not only increases the production cost, but also reduces the quality of the product
