The present application relates to a kind of Ni-Cu high chromium vanadium alloy cold roll steel and its preparation method, belong to steel preparation technical field.The cold roll steel is composed of the following chemical components according to mass percentage: C:0.76%~0.86%, Si:1.00%~1.20%, Mn:0.30%~0.40%, Cr:4.50%~5.60%, Mo:1.00%~1.20%, V:0.18%~0.25%, Ni:0.20%~0.35%, Cu:0.15%~0.25%, P≤0.015%, S≤0.010%, the rest is Fe and inevitable impurities.The cold roll steel prepared by optimizing alloy chemical composition and adjusting heat treatment parameters effectively adapts to the demand of modern cold rolling production line, greatly reduces the replacement cost of roll body and downtime loss, and provides reliable material and process guarantee for the quality and efficiency of cold rolling industry.

The utility model discloses a quantitative batching device for rice flour raw materials, which comprises a feeding bin, a vibrating feeder, a starch feeding hopper, a baffle plate adjusting mechanism, a box body, a blanking bin, a weighing sensor and a blanking adjusting mechanism, the feeding bin is provided with a first feeding hole and a second feeding hole, the vibrating feeder is used for conveying rice flour into the blanking bin in a vibrating manner, and the starch feeding hopper is used for conveying the rice flour into the blanking bin; the starch feeding hopper is used for conveying starch into the blanking bin, the baffle adjusting mechanism is used for adjusting the opening degree of the starch feeding hopper, the weighing sensor is used for detecting the weight of materials in the blanking bin, and the blanking adjusting mechanism is used for adjusting the opening degree of the blanking bin. The first feeding port and the second feeding port are formed in the feeding bin, so that rice flour and starch can be conveyed independently, and mixing is avoided; the blanking bin is used as a mixing space, and real-time monitoring of the weighing sensor is combined, so that accurate proportioning of raw materials according to a preset proportion can be ensured, the production efficiency and the processing quality of rice noodles are improved, and large-scale production requirements are met.

The utility model discloses a working table for sheet metal working. The working table comprises a supporting table used for bearing a sheet material. One side of the supporting table is movably connected with a first pushing piece, and the other side of the supporting table is movably connected with a second pushing piece; the second pushing piece comprises a supporting seat and a supporting rod rotationally mounted on the supporting seat; a first shaft pin seat is further arranged on the side, away from the supporting seat, of the supporting rod. The first shaft pin seat is connected with a second shaft pin seat; a pressing rod is slidably mounted in the second shaft pin seat, and the bottom of the pressing rod makes contact with the plate on the supporting table through an arranged pressing plate. When the first pushing piece and the second pushing piece are pressed downwards, the pressing plate is promoted to be compacted on the plates through the supporting rods, and the plates above are promoted to be separated from the plates below through movement of the pressing plate. On the basis, the equipment can quickly separate the stacked plates, so that an operator can take the plates conveniently, and the machining efficiency of the plates can be improved.
