The cutting device solves the problems that a cutting device is not provided with an anti-deviation mechanism, when the cutting device cuts an extruded sheet, the cut extruded sheet is prone to inclining, and the cut extruded sheet is unqualified, and solves the problem that a user cannot accurately cut the extruded sheet at a fixed length due to the fact that the cutting device is not provided with a positioning mechanism.

The utility model discloses a plastic pipe clamp forming device, belongs to the technical field of plastic pipe clamp production, solves the problem that a formed pipe clamp is unqualified due to the fact that a movable die and a fixed die of an existing device are prone to dislocation during die assembly, and comprises a U-shaped plate, and the movable die and the fixed die are arranged on the top face and the bottom face of the U-shaped plate respectively. A conical table is fixedly installed on the top face of the fixed mold, an inclined face is arranged on the edge of the top face of the fixed mold, a conical cavity with the same specification as the conical table is formed in the middle of the bottom face of the movable mold, a guide ring is fixedly installed on the bottom face of the movable mold, and an inner ring of the guide ring is an inclined face with the same inclination degree as the inclined face. The movable mold is pushed downwards through the air cylinder, the fixed mold and the movable mold are closed, during mold closing, the movable mold is guided through the conical table and the inclined face, finally, the conical table can be clamped in the conical cavity, the guide ring can be attached to the inclined face, the situation of dislocation between the fixed mold and the movable mold is avoided, and the yield of pipe clamp production can be increased.

The invention relates to a clamping method for stabilizing a weak-rigidity cantilever part, the weak-rigidity cantilever part is provided with a fixing part and a cantilever part, the fixing part can be fixed on a machining plane, and the cantilever part is suspended relative to the machining plane; according to the clamping method, a wedge-shaped supporting block and a dial indicator are used, the bottom of the wedge-shaped supporting block can horizontally move and slide on the machining plane, the wedge-shaped supporting block can be fixed on the machining plane when moving to a proper position, the upper portion of the wedge-shaped supporting block is an inclined face, and an included angle larger than zero degree is formed between the inclined face and the horizontal plane.

The utility model relates to the technical field of heating furnaces, and discloses a PLC-control-based shape-maintaining quenching automatic heating furnace oxygen introducing device which comprises a furnace body, a heating pipe, an oxygen probe, a main path oxygen supply pipeline, a branch path oxygen supply pipeline, an electromagnetic valve, a furnace door and a driving part. In the using process, the driving piece is controlled to work, and the furnace door can open or close the heating chamber. When the heating chamber is in a closed state, the workpiece loaded on the tray can be heated. When the heating pipe continuously generates heat to heat the workpiece, the oxygen probe can detect the oxygen content in the heating chamber in real time. When the oxygen content is lower than a standard value, the electromagnetic valve is controlled to be switched on, and oxygen can be conveyed into the heating chamber through the main oxygen supply pipeline and the branch oxygen supply pipeline. And after oxygen is conveyed for a set time, the electromagnetic valve is controlled to be blocked, so that the exhausted oxygen in the heating chamber can be supplemented. The problem that heated workpieces are often unqualified due to the fact that the oxygen content in the heating furnace is too low is solved, and the qualification rate of the workpieces is increased.
