Bar conveying device

The utility model discloses a bar conveying device which comprises a rack, at least one pair of conveying wheels are movably connected on the rack, and a clamping part is arranged on the conveying wheel. In use, a bar penetrates through the clamping part, and the surface of the clamping part is tightly contacted with the surface of the bar. Then one conveying wheel rotates to one direction, the other conveying wheel rotates to the opposite direction, the clamping part rotates along with the conveying wheels, and in rotation, friction force between the clamping part and the bar pushes the bar to move to one side to enter a punch press so as to punched to be broken off. A machine drives the conveying wheels to convey the bar, the feeding is steady, the situation that the feeding is not in place is not easy to occur, and the percent of pass of the product is greatly improved. The speed of machine feeding is much higher than that of manual feeding, and the production efficiency can be improved. Furthermore, manua
