The technical solutions provided by the embodiments of the present application are described below with reference to the accompanying drawings.

Referring to fig. 1 to 6, an embodiment of the present disclosure provides a device and a method for removing burrs of a rubber seal ring.

As shown in fig. 1, a rubber packing burr removing apparatus may include a lifting plate 5, a protection plate 4, and a cutting part 3.

The protective plate 4 is provided with a groove which is arranged along the length direction and used for positioning the sealing ring, and the bottom of the groove is provided with a gap which is arranged along the length direction of the protective plate 4; the cutting part 3 is arranged on the protective plate 4, and the cutting part 3 moves back and forth from one end to the other end of the gap along the length direction of the gap; wherein, lift 5 partial sealing washers of lifting and move to the groove to make the outer wall laminating of sealing washer at the inslot, and the produced deckle edge of sealing washer in the course of working passes the gap, deckle edge protrusion in protection shield 4, and 3 walking along the gap of cutting portion cut deckle edge.

It should be noted that, the opening direction in groove is towards lifting plate 5, lifting plate 5 arranges the below of protection shield 4 in, take partial sealing washer in lifting plate 5's top, and place on lifting plate 5 along lifting plate 5's length direction, lifting plate 5 laminates partial sealing washer in the cell wall after removing to the groove, the deckle edge on the sealing washer can pass the gap of tank bottom, so that deckle edge protrusion in protection shield 4, staff operates the cutting end of cutting portion 3 so that cutting portion removes to the other end by the one end in gap, the deckle edge excision that will pass the gap.

When making cutting portion 3 cut deckle edge through above-mentioned structure, only need the workman to hand cutting portion 3, reciprocating motion cutting portion 3 can, protect the workman through protection shield 4, need not the handheld sealing washer of workman, improved and got rid of deckle edge efficiency, avoided getting rid of the danger that deckle edge in-process can hinder the workman's hand.

As shown in fig. 4 and 5, in one embodiment, the protection plate 4 may include a first side plate and a second side plate, the first side plate and the second side plate forming a groove; the first side plate and the second side plate are separated by a certain distance to form a gap; the width of the gap is smaller than the section diameter of the sealing ring.

Large-scale non-standard article O type sealing washer can be at the outer wall of O type sealing washer at the in-process of processing, leaves the deckle edge on the annular compound die line, and the deckle edge is that can't avoid in the O type sealing washer course of working, and the deckle edge of O type sealing washer is rejected and is mostly needed workman's manual work to get rid of, needs workman's technique moreover comparatively skilled, if workman's operation is not skilled, can amputate and then influence the airtight effect of O type sealing washer with the outer wall part of O type sealing washer.

Because large-scale nonstandard article O type sealing washer is in the in-process of production, and not a large amount of productions are processed production according to customer's required length and cross-sectional diameter, consequently to conventional standard O type sealing washer deckle edge rejection equipment not be applicable to nonstandard piece.

For the above reasons, in intensive research and improvement of the rubber packing burr removing apparatus, the protection plate 4 and the lifting plate 5 are designed, and the protection plate 4 is designed to be composed of the first and second bead plates.
