Description

Stainless steel bar fixing clamp Technical Field The utility model relates to the technical field of stainless steel rod machining, in particular to a stainless steel rod fixing clamp holder. Background The main characteristics of stainless steel are stainless steel, corrosion resistance, chromium content is at least 10.5%, carbon content is at most 1.2%, the steel is short for stainless acid-resistant steel, weak corrosion medium such as air, steam, water and the like or steel with stainless property is called stainless steel, the steel with corrosion resistance of chemical corrosion medium (acid, alkali, salt and the like) is called acid-resistant steel, the corrosion resistance of the common stainless steel is different due to the difference of chemical compositions, the common stainless steel is not corrosion resistant of the chemical medium, the acid-resistant steel is generally stainless, the better steel also contains nickel, molybdenum can be added to further improve atmospheric corrosion resistance, particularly corrosion resistance of chlorine-containing compound atmosphere, and the hardness of part of the stainless steel is higher than that of aluminum alloy, but the cost is higher than that of the aluminum alloy, wherein the stainless steel bar is required to be positioned and clamped in the processing process. When the stainless steel piece needs to be moved, the clamping device and the moving device need to be adjusted and then pulled, so that the stainless steel piece is conveyed and moved, and the conveying efficiency of the stainless steel piece is low. Through retrieving, chinese patent with bulletin number CN222779164U discloses a fixed holder is used in processing of stainless steel bar material, when needs carry stainless steel bar material, start the cylinder for the inner circle of friction plate breaks away from with the outside of rod, and then makes the rod become flexible, then through screw mechanism, make the arc break away from the outside of rod, further make the rod become flexible, then start up the motor, under the effect of motor, can drive first conveying roller and rotate, thereby make, the rod can drive the turning ball and rotate in the inside of first soft board, and then be convenient for the staff transport and remove the rod.
