Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, in particular to a steel pipe cutting and pushing device. Background Art

[0002] At present, the process of cutting and transporting steel pipes is that the steel pipes are first cut from the cutting machine and then fall on the feed end of the conveyor belt. A baffle and a pushing mechanism are provided at the discharge end of the conveyor belt. The conveyor belt transports the steel pipe until it is blocked by the baffle and stops. Then the pushing mechanism pushes the steel pipe off the conveyor belt. The problem is that there are burrs on the edges of the steel pipes after they are cut. When the steel pipes are blocked by the conveyor belt, the burrs on the edges of the steel pipes will hang on the baffle, causing the steel pipes to be offset when being pushed by the pushing mechanism, and cannot be correctly pushed to the next process.

[0003] For example, the utility model patent with application number CN201721924600.2 records a steel pipe pushing mechanism, which records that when the steel pipe moves to contact the baffle, the baffle blocks the steel pipe, preventing it from moving forward. At the same time, the controller receives the signal and controls the motor to rotate one circle, the motor drives the turntable to rotate, the turntable drives the slider to reciprocate through the connecting rod, and the slider sends the steel pipe transported by the conveying unit into the collection tube. In this comparative document, when there are burrs on the edge of the steel pipe, they will hang on the baffle, causing the slider to fail to correctly push the steel pipe into the collection tube.

[0004] In summary, it is necessary to design a steel pipe cutting and pushing device to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problems existing in the above-mentioned prior art and provides a steel pipe cutting and pushing device. A liftable baffle is installed at the discharge position of the conveyor belt. When the steel pipe contacts the baffle, the baffle is slightly lifted and lowered reciprocatingly, so that the burrs of the steel pipe hung on the baffle are separated from the baffle, so that the pushing mechanism can correctly push the steel pipe to the next process.

[0006] The utility model adopts a technical solution to solve its technical problems: the steel pipe cutting and pushing device comprises a bottom plate, a pair of baffles fixed on the bottom plate, a conveying channel arranged between the pair of baffles, a conveying belt arranged in the conveying channel, and a steel pipe cutting machine arranged at the inlet of the conveying belt; the conveying channel is provided with a steel pipe baffle located at the outlet of the conveying belt and can be raised and lowered, and the pair of baffles are provided with steel pipe outlets and pushing pieces corresponding to the steel pipe outlets.

[0007] For further improvement, the baffle includes a front baffle and a rear baffle, the steel pipe outlet is opened on the front baffle, and the pusher is installed on the rear baffle.

[0008] For further improvement, a material guide slope located below the steel pipe outlet is provided on the outside of the front baffle.

[0009] For further improvement, the conveyor belt includes a number of mounting rollers rotatably connected between the front baffle and the rear baffle, a rotating wheel fixed on the outside of the mounting roller, and a belt sleeved on the outside of the rotating wheel. The mounting roller passes through the rear baffle, and a motor connected to the mounting roller is fixed on the rear baffle, and the motor drives the mounting roller to rotate.

[0010] For further improvement, the steel pipe material blocking member includes a fixed plate arranged in the conveying channel and located above the conveyor belt outlet, a material blocking plate arranged below the fixed plate and located at the conveyor belt outlet, a connecting rod fixed on the top of the material blocking plate and passing through the fixed plate, and a lifting cylinder installed on the top of the fixed plate and connected to the connecting rod.
