Q:The diameter of 20 solid round steel bend into a circle, what machine bending?
Worm and worm type steel bar benderStructure: worm and worm type steel bending machine, mainly each family, motor, transmission system, work mechanism (work disk, insert seat, gripper, shaft, etc.) and control system. A walking wheel is arranged under the frame for easy movement.Working principle: the power of the motor is rotated by the V belt pulley, the two straight gear and the worm gear rod, and then drives the working disk to rotate. The working disk usually has 9 shafts, the center hole is used to insert the central shaft, and the 8 hole seats around each have 6 holes, which are used to insert the retaining shaft. In order to move the reinforcing steel bar, two times of each work table is also provided with a feeding roller. When working, according to the bending shape of the steel bar, the square of the reinforcing steel bar is arranged between the central axis of the work disc and the corresponding forming shaft, and the inner side of the iron block is blocked. When the working disc is rotated, one end of the reinforcing bar is prevented from rotating by the iron blocking shaft, the central shaft position is fixed, and the forming shaft is rotated in an arc direction around the central shaft, and the reinforcing bar is bent.As a result of the specification, the bending diameter of the steel bar shall be no less than 2.5 times of the diameter of the steel bar when it is taken as a 180 degree bending hook. Therefore, the center shaft is also made into 16~100mm in 9 different specifications to meet the requirements of bending different diameter steel bars.
Q:Can steel bars be replaced by large screws in the concrete floor?
Tensile strength, extensibility, yield point! The same thread can be used instead!Of course, the number of roots must also be the same ~ only specifications vary!
Q:Why can't the grounding device be replaced by steel bar instead of round steel?
Steel is known as hot rolled ribbed bar. Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the brand. H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words. Hot rolled ribbed bar is divided into two levels, HRB335 (old No. 20MnSi), three HRB400 (20MnSiV, 20MnSiNb, old No. 20Mnti), four grade HRB500 three grade.
Q:What is the difference between cast iron and round steel?
Is also called round billet cast iron or iron by calcination with heavy machinery forging into steel (called the moral is toughened and hardened into steel or steel), the main component of alloy is composed of iron, carbon and silicon steel just according to the different areas in the use of alloy in carbon and silicon content in different precipitation in steel forging process of carbon and silicon was decreased to different areas of demand.
Q:Is there a steel bar of 6 diameter on the market?
There is no rebar of 6 diameter on the market.
Q:What's the difference between round steel and screw steel? Which is cheaper than steel on the market these days?
Round steel and thread steel are mainly made of different materials and purposes, so prices are different, and they need to be chosen according to actual needs.
Q:Excuse me and steel disc round what is the difference?
Wire rod refers to the hot-rolled steel bar of 5-22mm diameter or the special-shaped steel of this section. As a result of wire rod delivery, it is also known as wire rod.
Q:20 round bars are of several grades
No. 20 cold drawn steel belongs to high quality low carbon steel, cold extrusion, carburizing hardened steel. The steel has low strength, toughness, plasticity and weldability. The tensile strength is 355-500MPa, elongation is greater than or equal to 24%.
Q:What is the difference between gcr12 round bar and Cr12 round bar? Can it be used in general?
The chromium content of the two is very different, and the range of application is different.
Q:1, three, two, steel, wire rod, round steel what is the difference?
Steel is commonly known as hot rolled ribbed bar, belonging to the small steel steel, mainly used for steel reinforced concrete structure frame. In use, some mechanical strength, bending deformation property and welding performance are required. The raw steel billet for the production of threaded steel is carbon structural steel or low alloy structural steel which is treated by calm melting, and the finished steel bar is delivered in hot rolling forming, normalizing or hot rolling state.
