Abstract
The utility model relates to a sealing ring punching head, comprising a punching head body, the upper end of the punching head body is provided with a punching head handle, and the lower end of the punching head body is provided with a circular outer cutter and a circular inner cutter; the punching head handle can be arranged on a clamping head of a bench drill, the punching head can be kept a vertical movement to punch the sealing ring, a notch of the punching sealing ring is regular and smooth, and the demands of the shape and the size can be totally satisfied; furthermore, the utility model has the advantages of no waste, labour saving, and speediness. The utility model is suitable for rectangular sealing rings which are made of materials, such as punching leather, plastic, rubber, felt, etc.
Description
The utility model relates to a kind of drift of punching out seal ring.
In the prior art, stay dash can beyond, interior punching out respectively goes out the square RunddichtringO, is exactly not guarantee internal diameter and the requirement of external diameter coaxality, the seal ring of going out has the problem of width inequality on circumference, the pressure inequality of then bearing on equipment influences its sealability and working life.Stay to dash and use hammering, productive labor intensity is higher, and safety inadequately.
The purpose of this utility model is to provide a kind of seal ring drift, can carry out the seal ring of punching out various sizes on bench drill, but especially punching out goes out the square RunddichtringO that shape and size all can meet the demands, and boosts productivity and reduces labor intensity.
For achieving the above object, the utility model adopts following technical proposals:
A kind of seal ring drift comprises a punch body, it is characterized in that there is punch-holder shank the punch body upper end, and there are annular outer cut and annular inner cutter in the lower end.
Above-mentioned annular inner cutter and punch body are made one, annular outer cut and punch body drive fit, and by screw.
In the above-mentioned annular inner cutter and between annular outer cut and the annular inner cutter, the annular retaining ring by the spring supporting is housed respectively.
Bottom support is on the screw flange in the annular retaining ring in the above-mentioned annular inner cutter, and inner by the spring supporting, the annular retaining ring between annular outer cut and the annular inner cutter has convex shoulder to be supported on the internal shoulder of annular outer cut, and inner by yielding support.
The utility model compared with prior art, have following conspicuous characteristics and advantage: (1) this drift has punch-holder shank, can directly be contained on the bench drill chuck, make drift keep vertical motion, fill up parallel nylon sheet on the bench drill worktable, the moving bench drill handle of plate just can carry out the punching out seal ring, saves time, laborsaving.(2) there is the annular outer cut and the annular inner cutter of concentric the drift lower end, thereby can punching out go out the satisfactory seal ring of shape and size.(3) in the annular inner cutter and between annular outer cut and the annular inner cutter, back-up ring by the spring supporting is housed respectively, can increase annular inner cutter and the stability of annular outer cut in the punching out process, guarantee the quality of punching out seal ring, and in the punching out process, dash good seal ring and can from drift, eject automatically.The square RunddichtringO of the utility model punching out, otch is neat, smooth, and shape and size can both meet the demands, and do not have waste product, laborsaving, quick, less investment.Be applicable to the square RunddichtringO that materials such as punching out leather, plastics, rubber, felt constitute.
Accompanying drawing is an embodiment's of the utility model a structural representation.
An optimum implementation of the present utility model is: referring to accompanying drawing, this seal ring drift includes a punch body 2, and there is punch-holder shank punch body 2 upper ends, and there are annular outer cut 3 and annular inner cutter 6 in the lower end.Annular inner cutter 6 is made one with punch body 2, annular outer cut 3 and punch body 2 drive fits, and fixing by screw 10.In the annular inner cutter 6 and between annular outer cut 3 and the annular inner cutter 6, be equipped with respectively by spring 9,4 flexibly mounted annular retaining rings 8,5.Annular retaining ring 8 interior bottom supports are on screw 7 flanges, and the inner is by spring 9 yielding supports.Annular retaining ring 5 has convex shoulder to be supported on the internal shoulder of annular outer cut 3, and inner by spring 4 yielding supports.
