Description

Technical Field

[0001] The utility model relates to a straightening and cutting device, in particular to a straightening and cutting device based on titanium alloy medical materials, belonging to the technical field of medical material processing. Background Art

[0002] Titanium alloy medical materials refer to materials used for medical purposes to diagnose, treat, repair or replace human tissues and organs or enhance their functions. Medical materials used to make various artificial joints and artificial bones in orthopedics include polymer materials, metal materials, non-metallic materials and composite materials, but these materials need to be straightened and cut before they can be made into various human tissues.

[0003] In the prior art, for example, a device for straightening and cutting steel bars for precast concrete parts and manhole covers disclosed in announcement number CN215392219U, when it is necessary to straighten and cut the steel bars, the steel bars are first inserted into the straightening roller set, and then pass through the straightening channel into the traction roller set; the traction roller set is driven by a driving motor to rotate, and driven by the traction roller set, the steel bars continue to enter the straightening roller set and the straightening channel for straightening.

[0004] When the above technical solution is in use, the steel bar is first placed into the straightening roller group, then passes through the straightening roller group into the straightening channel, and then enters the traction roller group through the straightening channel. After the steel bar enters the traction roller group, the traction roller group is driven to rotate by the driving motor to pull the steel bar so that the steel bar can be straightened by the straightening roller group and the straightening channel. However, in actual use, since the distance and size between the rollers are fixed and the size of the traction channel is fixed, only steel bars of fixed size can be straightened. When straightening steel bars of different thicknesses, the rollers of fixed size and distance will make the straightening effect of the device on the steel bar worse, thereby resulting in the problem of low device utilization. In view of this, a straightening and cutting device based on titanium alloy medical material is provided to overcome the above defects. Utility Model Content
