TECHNICAL FIELD

[0001] The utility model relates to straightening machine field, specifically a kind of titanium bar cold-drawing straightening machine. BACKGROUND

[0002] When the bending, distortion and other defects of titanium bar and other metal bars are generated in the cold-drawing process, the titanium bar cold-drawing straightening machine is needed to straighten the defects of the titanium bar bending. The straightening machine straightens the titanium bar after cold-drawing treatment by mechanical or hydraulic means, so that the titanium bar can recover to the specified straightness requirement, thereby improving the product quality and use performance of the titanium bar.

[0003] At present, when the titanium bar is pressed and straightened by hydraulic transmission, the straightening die presses and straightens the titanium bar when it is pressed down. At this time, the titanium bar is pressed and bent by itself. The titanium bar is straightened by reciprocating. However, after the straightening die is separated from the titanium bar, the titanium bar may pop up under the action of the elastic force, which may cause the titanium bar to separate from the lifting platform, thereby affecting the subsequent straightening process and processing efficiency, and even causing safety hazards. Therefore, a titanium bar cold-drawing straightening machine is proposed to solve the above problems. SUMMARY

[0012] The utility model discloses the beneficial effect lies in:

[0013] During the process that the pressing plate moves downward and straightens the titanium rod body, at this time, the two connecting springs approach the titanium rod body, when the pressing plate moves on the line and separates from the titanium rod body, if the titanium rod body rebounds upward at this time, the titanium rod body is limited by the connecting spring, so that the titanium rod body is prevented from separating from the supporting table due to a large rebound amplitude, at this time, the operator does not need to reposition the titanium rod body, the straightening efficiency is improved, in addition, the titanium rod is prevented from rebounding with a large amplitude and hurting the operator, thereby improving the safety.
