摘要
针对100kN万能材料试验机现有的弯曲机具不能满足型材弯曲试验的要求,进行了弯曲机具的研制。新机具由上压头、下压板、机具架和标尺组成。试验时,可以很方便地装卸试样,正面观察角度好,用透明标尺测量压下量,弯心的压下尺寸便于控制,完全满足了GB/T701-1997《低碳钢热轧圆盘条》标准中的具体要求,保证了型材弯曲试验的准确性。
In view of the fact that the bending tool for 100kN universal testing machnie can not satisfy the requirement of high qualified bending testing of section materials. It is prosposed to develope a kind of bending tools for 100kN universal testing machine in this paper. The new tool consists of up-pressing head, down-pressing board, tool frame and scale. When testing, the specimen can be easily loaded and unloaded also can be observed clearly from the front. The transparent scale is used to measure the amount of pressing deflection and the amount of core dimensions can be easily controlted. It completely meets the requirement of standards for hot rolled and low carbon wire rod (GB/T 701-1997) and ensure the accuracy of bending tests on section meterials.
