Description

Technical Field

[0001] This utility model relates to the field of valve steel bar processing technology, specifically a valve steel bar straightening and cutting device. Background Technology

[0002] Currently, valve steel refers to a type of steel suitable for manufacturing various valves. It is an essential material for manufacturing intake and exhaust valves of gasoline and diesel engines and a key material in the entire engine. After production, valve steel inevitably requires straightening and cutting.

[0003] The authorized publication number "CN220679011U" describes "a device for straightening and cutting a valve steel bar, the key technical points of which include: a load-bearing plate, a straightening box fixedly installed on the top surface of the load-bearing plate, two rollers inside the straightening box, limit holes inside the rollers, two rotating rods inside the straightening box, the outer circular wall of the rotating rods being fixedly fitted with the inner wall of the limit holes, the operator inserts the valve steel bar through the straightening inlet, and the rotating rods are driven to rotate by a first drive motor, which in turn drives the rollers to rotate, and the rotation of the two rollers generates compression to effectively straighten the valve steel bar, the straightening guide tube can effectively prevent the valve steel bar from deforming and damaging other structures inside the straightening box due to the lack of a fixing device when it is straightened inside the straightening box, and the protective cover can effectively prevent metal fragments generated by the cutting blade when cutting the valve steel bar from injuring people."

[0004] The aforementioned patent allows the valve steel rod to be inserted into the straightening inlet. A first drive motor is set up to drive the rotating rod to rotate, which in turn drives the roller to rotate. The rotation of the two rollers generates compression, thereby effectively straightening the valve steel rod. However, in practice, this straightening method is too simplistic, only able to straighten the valve steel rod in the vertical direction, lacking straightening on the left and right sides.
