Description

Annular pad one-shot forming cutting machine

Technical field

The utility model relates to a kind of relevant pipeline, valve type equipment is tightly connected with the improvement of the cutting tool of annular gasket, specifically a kind of annular pad one-shot forming cutting machine.

Background technology

The annular pad is existing pipeline, valve type equipment junction seal, this seal rapid wear, and the turnover rate height, demand is big.The source of annular pad is purchased the part except that the special annular pad of part adopts, and the overwhelming majority needs to make by hand by the demand size at the construction field (site).Therefore, the annular pad is made at the scene by hand becomes the technical ability that each maintenance personal must grasp.Usually the step of making the annular pad by hand is: the size of measuring channel or the inside and outside diameter of valve flanges at first; Measure the size of planing between the two arm pull tops again; Making the inside and outside circle that draws on the flitch then; Once shear out required annular pad along inside and outside circle respectively with scissors at last.This deficiency of making the annular pad by hand is: Production Time is long, efficiency is low, the making error is big, waste of material is many, and when material hard with quality especially, that thickness is bigger is made (as the hard tetrafluoro plate of 5mm, asbestos board), manufacture difficulty is just bigger, and bowlder in cutting, often need cut out long shearing guide groove earlier, cause great waste of material, the requirement of engineerings such as incompatible modernization installation repairing.A kind of annular pad one-shot forming pressing mold is also arranged at present, though can one-shot forming, can not the random variation size, the specification difference then needs different moulds, so use inconvenient.

Summary of the invention

The purpose of this utility model is to provide a kind of simple in structure, easy to use, time saving and energy saving, convenient for maintaining operation, reduce labour intensity, reduce the annular pad one-shot forming cutting machine of pad cost of manufacture.

For reaching above purpose, the technical scheme that the utility model adopted is: this annular pad one-shot forming cutting machine, constitute by center of circle pilot pin and center rotating shaft, center rotating shaft is fixed on the seat end of center of circle pilot pin, and, the axis of center rotating shaft and center of circle pilot pin point-blank, it is characterized in that fixing crossfoot on the needle stand of center of circle pilot pin, the axis normal of crossfoot and center of circle pilot pin, fixing inside and outside round cutter head respectively by inside and outside transparent sliding sleeve on the crossfoot, fix turning handle in the outer end of crossfoot.The utility model is also implemented by following measure: sheathed hand-held cover on center rotating shaft, establish upper and lower retainer ring respectively at the upper and lower end of hand-held cover; Travelling gear is established in upper end at center rotating shaft; On inside and outside transparent sliding sleeve, set the position bolt respectively; Described center of circle pilot pin is a hemicone; The lower end of circle cutter head is and center of circle pilot pin hemicone in opposite directions in described; Described cylindrical cutter head also is a hemicone, and the plane of its hemicone is towards the center of circle; It is that 2mm, thickness are the spiral bit of 1mm that inside and outside circle cutting crop can adopt width.

The beneficial effects of the utility model are: compare with making the annular pad at present by hand, owing to can once finish concentrically ringed cutting, so, can reduce labour intensity, save time, to increase work efficiency, size Control is accurate, reduces waste of raw materials.Can be widely used in pipeline, the valve type maintaining equipments.

The specific embodiment

Make the utility model with reference to accompanying drawing 1.This annular pad one-shot forming cutting machine, constitute by center of circle pilot pin 1 and center rotating shaft 2, center rotating shaft 2 is fixed on the seat end of center of circle pilot pin 1, can be made as an integral body, and, the axis of center rotating shaft 2 and center of circle pilot pin 1 point-blank, it is characterized in that fixing crossfoot 3 on the needle stand of center of circle pilot pin 1, the axis normal of crossfoot 3 and center of circle pilot pin 1, on the crossfoot 3 by inside and outside transparent sliding sleeve 4,4 ' respectively fixing inside and outside round cutter head 5,5 ', in the outer end of crossfoot 3 fixing on turning handle 6.Sheathed hand-held cover 7 on center rotating shaft 2, the upper and lower end of hand-held cover 7 establish respectively upper and lower retainer ring 8,8 '; Establish travelling gear 9 in the upper end of center rotating shaft 2,, the driving chain of motor can be connected with travelling gear 9 if when adopting electric motor operated; Inside and outside sliding sleeve 4,4 ' above set respectively a position bolt 10,10 '; Described center of circle pilot pin 1 is the semicircle cone; The lower end of circle cutter head 5 is and center of circle pilot pin 1 hemicone in opposite directions in described; Described cylindrical cutter head 5 ' also be hemicone, the plane of its hemicone is towards the center of circle; Inside and outside round cutter head 5,5 ' can adopt width is that 2mm, thickness are the spiral bit of 1mm.Trouble during the sum of errors cutting that brings for circle cutter head 5mm width in eliminating, with mechanical zero be positioned crossfoot 3-2mm place, when making annular pad, just need not consider the error that causes because of interior round cutter head 5 width like this.In when operation inside and outside sliding sleeve 4,4 ' is directly moved to required size,,, can disposablely cut out required annular pad by rotation turning handle 6 with bolt 10,10 ' fixing.When using the utility model, if rotate the turning handle cutting by hand, its operating procedure is: (1) obtains its radius respectively after measuring the inside and outside footpath of installation workpiece connecting portion size; (2) by move inside and outside transparent sliding sleeve 4,4 ', make inside and outside cutter head 5,5 ' to the radius distance value point of inside and outside footpath, usefulness bolt 10,10 ' location; (3) at last center of circle pilot pin 1 is placed the center of circle, a hand-held cover 7 compresses, and the another hand-screw is walked around 6 one weeks of fixed handle, can cut inside and outside circle simultaneously.If adopt the motor cutting, the motivation driving-belt that can Connect Power on travelling gear 9 gets final product.
