Embodiment Construction
[0008] Referring to the accompanying drawings, the groove-shaped clamping frame 2 is made by cutting a whole piece of 10mm thick manganese steel, and the depth of the groove shape is 180mm; Above; the hand handle 3 is made of Φ12mm round steel, welded in a groove shape above the clamping frame, and the size is 150mm×90mm; the saddle-shaped pressing block 4 is processed from a round steel with a diameter of 50mm and a length of 54mm, and its rear end is A hole with a diameter of 40mm, an inner diameter of 30mm, and a depth of 30mm, and a 5mm screw hole is drilled at 10mm from the rear end of the compression block, so that the screw goes deep into the groove on the screw rod 5 to prevent the compression block from coming off the screw rod. The front end of the saddle-shaped pressing block is processed into a 150° arc, the diameter of the screw 5 is 30mm, and the length is 300mm. The front end of the screw is processed into a diameter of 28mm and a length of 30mm, and a 5mm×5mm gr...

The invention relates to a steel coil jig, in particular to a steel coil sampling jig to prevent the steel coil from loosening applicable for vertical coil sampling production of high tensile steel coils. The invention primarily solves the technical problem that the coils are loosened when the high tensile steel is sampled and cut. The technical proposal of the invention is that the steel coil sampling jig to prevent the steel coils from loosening comprises a groove-shaped clamping frame, and is characterized in that battens are fixed on both ends of the inner side of the clamping frame; a nut is fixed below the back end of the clamping frame; a lead screw is screwed inside the nut; a saddle-shaped impaction piece is fixed on the front end of the lead screw; a shrinkage control crank is fixed on the back end of the lead screw; the front end of the saddle-shaped impaction piece is cambered; a hand-held handle is fixed on the upper surface of the groove-shaped clamping frame. The invention is primarily used to prevent the steel coil from loosening during vertical coiling, sampling and production of high tensile steel.
Description
Technical field: [0001] The invention relates to a steel coil clamp, in particular to a steel coil sampling and anti-loose coil clamp suitable for the production of high-strength steel coil vertical coil sampling. Background technique: [0002] Steel coil sampling is a technical requirement of iron and steel enterprises, mainly for the detection of product performance and chemical composition, especially for high-strength steel with high sampling density and large cutting volume. In the past, steel coils were sampled in the way that the steel coils leaned against each other, which seriously damaged the surface of the steel coils. As a result, the loose coils after sampling were very serious, and the sampling parts did not meet the requirements, resulting in repeated samples. Increase, the cost of cutting or repairing during material preparation will increase, and it will have an adverse effect on the roll shape. The overall yield of hot-rolled steel coils has been reduced. ...
