Description

Technical Field

[0001] The utility model relates to the technical field of forging auxiliary equipment, in particular to a device for removing oxide scale on the surface of forgings by multi-directional spraying. Background Art

[0002] When a forging is being upset, the forging pressure will separate the oxide layer on its surface to form oxide scales. These oxide scales are either adhered to the forging or have been separated from the forging but still cover the forging. During the next forging, these oxide scales (especially the oxide scales on the top of the forging) may be pressed into the forging and destroy the metal layer on the surface of the forging, causing defects such as folding, slag inclusions, and cracks on the surface of the forging. Therefore, when upsetting forgings, it is necessary to remove the oxide scales on the surface of the forging (especially the top of the forging).

[0003] The commonly used removal method is for workers to use a handheld spray gun to spray high-pressure air to clean it. This method consumes manpower and is often not cleaned thoroughly. For example, if the spray gun cannot spray in place on the side against the wall, it is difficult to clean. Patent CN201320395876 is a billet upsetting descaling device. An airflow nozzle is set obliquely upward on the upsetting lower die, which can automatically spray and clean, but cannot clean the top scale of the forging. Therefore, how to save manpower and quickly remove the surface of the forging, especially the scale on the top of the forging, is of great significance to the quality of the upsetting forging.

[0004] The utility model aims to address the deficiencies of the prior art and to provide a device for removing oxide scale on the surface of forgings by multi-directional spraying. A device for spraying toward the forgings from all sides is arranged on the upper press of the forging equipment, so that the spraying device can rise with the upper press and spray the forgings from bottom to top in sequence during the rising process, thereby fully cleaning the oxide scale on the surface of the forgings, especially on the top.

[0005] The utility model solves the technical problem by adopting the following technical solution: a device for removing oxide scale on the surface of forgings by multi-directional spraying, comprising an upper press and a workbench, wherein the upper press is provided with at least two nozzles for spraying at the forgings from different directions, the nozzles are connected to a pressure pump through a pipeline, and a switch device for controlling on-off and flow is provided on the pipeline.

[0006] Preferably, the upper press is provided with an upsetting upper die, the workbench is provided with an upsetting lower die, and the nozzle is flush with the bottom of the upsetting upper die.

[0007] Preferably, an annular tube is provided on the outer periphery of the upsetting upper die, and the annular tube has four nozzles evenly distributed circumferentially. The annular tube is connected to the pressure pump through the pipeline, and the annular tube is fixedly connected to the upper press through a suspension rod.

[0008] Preferably, the switch device comprises a solenoid valve arranged on the pipeline, and the solenoid valve is electrically connected to a foot switch.

[0009] Preferably, the nozzle is directed toward the center of the annular tube and downward at an angle of 15° to 45° with the horizontal plane.

[0010] The beneficial effects of the utility model are: a device for removing oxide scale on the surface of forgings by multi-directional spraying, which includes an upper press and a workbench, the upper press is provided with at least two nozzles for spraying at the forgings from different directions, the nozzles are connected to a pressure pump through a pipeline, and a switch device for controlling on-off and flow is provided on the pipeline. The utility model sets the nozzle on the upper press, so that the nozzle can be raised and lowered with the upper press, so that the forgings can be sprayed from bottom to top when rising, especially the top of the forgings, thereby improving the efficiency and quality of removing oxide scale on the surface of the forgings, and also borrowing forging equipment, saving manpower.
