Abstract
The utility model discloses a double-cutter girdling gauge for flange pads with adjustable circle center height, which belongs to the technical field of machinery manufacturing. A circle center needle is fixed at one end of a rod-shaped gauge body, and an inner cutting knife and an outer cutting knife are movably installed in the other end of the rod-shaped gauge body. The distance between the inner cutting knife and the circle center needle is adjusted to be equal to the inner diameter of the flange pad, and the distance between the outer cutting knife and the circle center needle is equal to the outer diameter of the flange pad. Annular flange pad blanks can be cut in one step by rotating the girdling gauge. Therefore, the work efficiency doubles that of a single-cutter girdling gauge. The double-cutter girdling gauge is used for manufacturing the flange pad blanks.
Description
Technical field
Machine-building.
Background technology
Need to make various flange gasket bases in the machine-building, current methods has two big types: one type is the stamping method, and another kind of is the ring cutting method, and what use the most extensively is the ring cutting method, and the ring cutting method is used to such an extent that be ring cutting rule, and promptly on shaft-like rule body, an end is being fixed center of circle pin; The other end is being fixed cutting knife, on sealing plate, with the same center of circle, draws circle as compasses, rotates cutting knife, and cutting out two annular plates between concentric circles is flange gasket bases, and existing hilted broadsword ring cutting rule need ring cutting twice, just can make, and efficient is low.
Summary of the invention
On the high adjustable double-pole ring cutting rule in the flange gasket center of circle two cutting knifes are housed, rotate and once can be cut into a flange gasket base, the high adjustable double-pole ring cutting rule in the flange gasket center of circle (accompanying drawing) are made up of rule body 2, center of circle pin 1, inner cutter 3, outer cut 4, jackscrew 5, locknut 6.Center of circle pin 1 is fixed on an end of rule body 2.Inner cutter 3, outer cut 4 removable mountings are at the other end of advising body 2, and both all are slidingly matched with rule body 2, are fixed in rule body 2 arbitrfary points after the slip positioning.
Before the use, rotate center of circle pin 1 adjusting center of circle height, make the needle point of confirming the center of circle and inner cutter 3, outer cut 4, the point of a knife line that exists together, and locked with locknut 6.During use, set up the distance of inner cutter 3 points of a knife and center of circle pin 1 needle point earlier according to the inside radius of flange gasket.Set up the distance of outer cut 4 points of a knife and center of circle pin 1 needle point again according to the flange gasket outer radius.On sealing plate, select the center of circle then, an eye punching pin is got center of circle eye.Pin sealing plate on the other hand, another holds center of circle pin 1 one ends of rule body 2, and pin 1 needle point in the center of circle is pricked on the center of circle eye that just has been washed into, and rotates rule body 2, just on sealing plate, cuts out a sealing gasket base.
The advantage of the high adjustable double-pole ring cutting rule in the flange gasket center of circle is: production efficiency doubles than hilted broadsword ring cutting rule, and the pad base size that is cut into is accurate.
Description of drawings
Accompanying drawing is the high adjustable double-pole ring cutting rule structural representation in the flange gasket center of circle.
