Technical Field

The invention relates to the technical field of gasket processing equipment, in particular to a deburring mechanism for a metal gasket.

Background

The washer is a member that is placed between the member to be connected and the nut, and is generally a flat metal ring that protects the surface of the member to be connected from being scratched by the nut and distributes the pressure of the nut against the member to be connected. The edge of the contour of the gasket is usually provided with a lot of burrs after being subjected to stamping forming, the phenomenon is particularly prominent under the condition that the thickness of the gasket is thick, the appearance of the gasket is not good, the feel is rough, and the mechanical performance of the gasket is influenced sometimes, so that the deburring treatment of the surface of the gasket is generally carried out after the gasket is subjected to the stamping forming.

The existing gasket deburring device comprises a support and a closed cylinder body which is arranged in a regular polygon prism shape, a motor is fixed on the support, an output shaft of the motor extends axially along the cylinder body and is fixedly connected to the cylinder body, a material door which can be opened and closed is arranged on the side portion of the cylinder body, and sawdust is also placed in the cylinder body. In the deburring process, the motor will drive the barrel rotatory, and the packing ring in the barrel will collide each other, and the packing ring still rubs with the saw-dust each other for burr on the packing ring is got rid of, and the greasy dirt on the packing ring can also be got rid of to the saw-dust, has improved the luminance brightness of packing ring.

However, after burr and greasy dirt on the saw-dust will be got rid of the packing ring, if directly fall all saw-dust in the barrel, then comparatively extravagant, if use the saw-dust secondary in the barrel, be used for getting rid of burr and greasy dirt on the follow-up packing ring, then the effect of deoiling dirt and burring is relatively poor, for satisfying the quality requirement, this part packing ring need use the saw-dust of two to three section of thick bamboos secondary uses to deoil dirt and burring for the machining efficiency of packing ring is comparatively low, consequently needs to improve.
