[0002] At present, some materials such as steel pipes have a vertical 90-degree cross-section after being cut or made into semi-finished products. Usually, the 90-degree angle needs to be chamfered to meet application needs. A chamfering machine is a small precision machine tool that is professionally used for chamfering and removing burrs of products processed by milling and planing in mold manufacturing, hardware machinery, machine tool manufacturing, hydraulic parts, valve manufacturing, and textile machinery. A chamfering machine is usually used to chamfer circular steel cross-sections. Most of the chamfering machines on the market are single-head chamfering machines, which can only chamfer one end of circular steel at a time. Double-head chamfering takes a lot of time.

The loading process of the chamfering machine is that the slider first drives the movable clamp to slide to the rearmost end of the slide rail, and multiple round steels in rod shape are placed in the unloading channel to stack the round steels in the vertical direction. Then the slider drives the movable clamp to slide forward, and the movable clamp pushes the round steel at the bottom of the unloading channel to move forward until it abuts against the top material unit, and the round steel is clamped between the movable clamp and the top material unit. The three slide forward together until the round steel abuts against the fixed clamp so that the round steel is fixedly clamped between the movable clamp and the fixed clamp, thereby realizing the loading process of the round steel. After the chamfering processing at both ends of the round steel is completed, the slider moves backward, and the round steel workpiece after the chamfering processing is completed is separated from the movable clamp and the fixed clamp, and the unloading is completed; when the slider passes directly below the unloading channel along the slide rail, the round steel to be processed in the unloading channel falls to the bottom of the unloading channel, and the slider slides forward to drive the movable clamp to move forward, and the movable clamp pushes the round steel at the bottom of the unloading channel to move forward until it abuts against the top material unit, and the cycle is repeated in sequence.

The clamping chamfering device slides in the horizontal direction along the guide rail to increase or decrease the distance between the two clamping chamfering devices on the guide rail.
