Description

Round steel clamping, fixing and conveying device

Technical Field

The utility model relates to a round steel processing technology field specifically is a round steel presss from both sides tight fixed conveyor.

Background

The wedge cross rolling means that the cylindrical blank is continuously and locally deformed between dies of two rollers or between two flat dies, and the shape of the rolled part is consistent with that of a groove at the bottom of the die. When the cross wedge rolling production operation is carried out, round steel needs to be conveyed to a heating furnace through a conveying device for heating treatment, and the heated round steel is further conveyed into a cross wedge rolling mill for rolling. Devices for carrying out the transport by means of the cooperation of a pushing cylinder and a clamping wheel have been developed in the day before for this operation. However, the device has the following defects in the use process: firstly, in order to ensure the rolling precision and reduce the waste head output rate of the round steel to the maximum extent during heating and rolling, the length of each feeding needs to be accurately limited, and the length of each feeding of a pushing cylinder is not easy to control, so that the waste head output rate is too high, and the waste of steel is caused; secondly, in the rolling process, the blank can generate axial deformation under the action of the two rollers, the round steel needs to move backwards for a certain distance to ensure the rolling accuracy, and the operation cannot be accurately realized by a conveying device in the day before

Chinese patent (No. CN 204934212U) discloses a round steel clamping and conveying device, but the conveying distance of the round steel can be effectively and accurately limited by a stepping motor, so that the rolling precision is ensured, the yield of the waste heads of the round steel is reduced to the greatest extent, and steel is saved; however, the patent also has certain defects, and the whole device cannot be consistent with the conveying mechanism when the device is limited.
