Electrostatic spraying process device for fine blanking machine

Abstract

The invention relates to an electrostatic spraying technology device for a fine blanking machine. The electrostatic spraying technology device comprises a bracket, an electrostatic spraying system anda swing reciprocating mechanism; the electrostatic spraying system comprises an oil storage box, spraying system motors, pressure pump shafts, pressure valves and electrostatic spray guns; the oil storage box communicates with the pressure valves through an oil feeding pipeline, the pressure valves communicate with the electrostatic spray guns through spray gun pipelines, the spraying system motors are installed on the bracket, output shafts of the spraying system motors are connected with the pressure valves through the pressure pump shafts, the spraying system motors drive the pressure pumpshafts to rotationally squeeze the pressure valves, fine blanking lubricating oil is conveyed from the oil storage box to the electrostatic spray guns, and accordingly, the lubricating oil is sprayedonto to-be-sprayed plates; and the swing reciprocating mechanism is arranged on the bracket, the electrostatic spray guns are fixed to the swing reciprocating mechanism, and the swing reciprocating mechanism drives the electrostatic spray guns to do horizontal reciprocating motion. According to the electrostatic spraying technology device, synergistic action of the swing reciprocating mechanism and the spraying system motors is controlled through a PLC control system, and full-automatic electrostatic spraying of the to-be-sprayed plates can be achieved.

Description

technical field [0001] The invention relates to the technical field of spraying devices, in particular to an electrostatic spraying process device for a fine blanking machine. Background technique [0002] Fine blanking is to use the fine blanking die on a special press or a refitted press to make the sheet material be purely sheared and separated along the required contour under the three-way pressure state, so that the section of the punched part is smooth, vertical, and has good flatness. High precision. The dimensional accuracy can reach IT6-IT9, the hole distance tolerance is 0.01-0.05mm, the shear surface roughness is Ra0.4-1.6, and the bright band can reach 100% of the plate thickness. Using the precision blanking process instead of cutting to manufacture disc-shaped precision contour parts, the processing efficiency can be increased by more than ten times, and the production cost is greatly reduced. At present, the application field of fine blanking technology has ...
