Abstract
The utility model provides a flexible chamfering tool of blade formula of floating, including blade disc, handle of a knife, blade, its characterized in that: be equipped with the screw hole on the blade disc, the blade adopts the mode of floating to inlay on the sword groove of blade disc, the one end that the blade is arranged in the centre bore is equipped with down hook limb, and messenger's blade drops in can not following the sword groove, a polyurethane elastomer arranges blade disc inner chamber, the medial surface and the polyurethane elastomer contact of blade in, it is as an organic whole handle of a knife, polyurethane elastomer, cutter connection that mounting screws passes handle of a knife, polyurethane elastomer. Use the utility model discloses, the blade can compress elastic element ( polyurethane elastomer ) is proper amount according to mouth of pipe shape, and the blade can float under elastic element's effect to this can evenly cut the oval mouth of pipe or the mouth of pipe that loses behind the circle, obtains even chamfer, this cutter all can be got rid of the pipe mouth of pipe and the orificial closed angle burr of elliptical tube, can realize the flexible processing of multiple specification mouth of pipe chamfer.
Description
Technical field
The utility model belongs to a kind of instrument to cast part pipe orifice burr chamfering, and to removing, metal material type pipe is all applicable with the pipe orifice burr moulding pipe, and it is the flexible chamfering tool of a kind of floating knife chip.
Background technology
Cast part is widely used in the liquid of the industry such as automobile and household electrical appliances, gas conveying and anatomical connectivity, mainly makes the anatomical connectivity part of the parts such as the liquid line of automobile, tracheal tube and air-conditioning, the liquid line of refrigerator and automobile.Wedge angle burr after cast part needs line up to process in process carries out chamfering removal, otherwise affects body flow path and Assembly of the parts.
Existing cutter can even chamfering to circular ports, but loses the uneven or burr of the mouth of pipe chamfering after circle to elliptical tube or processing and remove thoroughly (as shown in Figure 1, chamfering A is uneven).Existing cutter adopts single blade soldering to fix or bolt is fixed, and the easy tipping of blade damages, and non-exchange or replacing difficulty after blade abrasion.Existing cutter, is often only suitable for the close mouth of pipe chamfering of a few specification cutter.
Summary of the invention
The utility model proposes the flexible chamfering tool of a kind of floating knife chip, can even chamfering to the pipe mouth of pipe and the elliptical tube mouth of pipe.Can quick-replaceable blade after blade abrasion.The mouth of pipe specification limit that cutter is suitable for is larger.
The technical solution of the utility model is: the flexible chamfering tool of a kind of floating knife chip, comprises cutterhead, handle of a knife, blade, elastomer, it is characterized in that: cutterhead is provided with screwed hole, and blade adopts floating structure to be embedded on the cutter groove of cutterhead; One end that blade is arranged in centre bore is provided with barb arm, and blade can not be come off from cutter groove; A polyurethane elastomer is placed in cutterhead inner chamber, and the inner side end of blade contacts with polyurethane elastomer; A mounting screw connects as one handle of a knife, polyurethane elastomer, cutterhead through handle of a knife, polyurethane elastomer.
Beneficial effect: use the utility model, blade can compress flexible member (polyurethane elastomer) in right amount according to orifice configuration, blade can float under the effect of flexible member, evenly can cut, obtain uniform chamfer dimesion with this to the oval mouth of pipe or the mouth of pipe after losing circle; The wedge angle burr of this cutter to the pipe mouth of pipe and the elliptical tube mouth of pipe all can be removed, and chamfering is even, can realize the Flexible Manufacture of plurality of specifications mouth of pipe chamfering, and one larger for the mouth of pipe specification limit that cutter is applicable.
Accompanying drawing explanation
Fig. 1 is the chamfering state diagram of existing cutter to the oval mouth of pipe.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the chamfering state diagram of the utility model to the oval mouth of pipe.
Detailed description of the invention
As shown in Figure 2, further describe the utility model as follows: the flexible chamfering tool of a kind of floating knife chip: comprise cutterhead 1, polyurethane elastomer 2, handle of a knife 3, mounting screw 4, blade 5, cutterhead 1 is provided with screwed hole, and blade 5 adopts floating structure to be embedded on the cutter groove of cutterhead 1; One end that blade 5 is arranged in centre bore is provided with barb arm (as shown in Figure 3), and blade 5 can not be come off from cutter groove; Polyurethane elastomer 2 is placed in the inner chamber of cutterhead 1, and the inner side end of blade 5 contacts with polyurethane elastomer 2, and mounting screw 4 connects handle of a knife 3, polyurethane elastomer 2, cutterhead 1 and is integrated through handle of a knife 3, polyurethane elastomer 2.
Use the utility model, blade 5 can compress flexible member (polyurethane elastomer 2) in right amount according to orifice configuration, because blade 5 can float under the effect of flexible member, evenly can cut the oval mouth of pipe or the mouth of pipe after losing circle with this, obtain uniform chamfer dimesion; As shown in Figure 3, be exactly adopt the utility model to the chamfering state of the oval mouth of pipe, chamfering B is uniform.
As shown in Figure 2, the floating structure of blade 5: blade and cutter groove matched in clearance.The gap of blade and cutter groove is generally selected in the scope of 0.05-0.15 millimeter.
As shown in Figure 2, adopt 6 blades, the most stable during chamfering.In the utility model, the quantity of blade is selected more than 3, can achieve the goal.
The advantage that the utility model possesses:
1) can to the even chamfering of the oval mouth of pipe;
2) cost of charp tool more than 50% is saved.Compare existing blade fixed tools, a nut only dismantled by this cutter just to all blade exchanges, can avoid the whole tool failure because of blade abrasion;
3) make the cutter of 70% less, enhance productivity 6%, one larger for the tubing model scope that cutter is applicable; The cutter of specification as shown in Figure 2 to the mouth of pipe chamfering of internal diameter 15-60mm, can reduce the quantity purchase of cutter, reduces tool changing tool number of times, enhances productivity.
