Description
Technical field
The present invention relates to a kind of instrument for expanded material boring, particularly relate to the hollow blade getting hole for soft material rule that one is applied to soft material on workpiece (as macromolecular materials such as polyurethane) boring or reaming, the regular circular hole through hole being applied to the foaming rear box such as white domestic appliances refrigerator, refrigerator, showcase makes.
Background technology
The reamer that existing market is sold, mostly be hole enlarging broach, be generally applied to the hole enlarging broach with circle trimming function of tubing etc. and the reaming of hard material circle trimming function, this reamer heavier-weight, when the flow work, labor strength is large, and everyone per tour 8 hours is passable; Production in conjunction with present household appliances enterprise is actual, a kind of reamer is not yet had to be specially adapted for the removing of soft material as technique clouts such as foamed materials, therefore generally all fluted drill is adopted, there is the defects such as adhesion, hole irregularity, breakage in spiral bit when being applied to soft material boring on workpiece, and large to parts harm, serious causes scrapping of casing.
Summary of the invention
The present invention, in order to solve weak point of the prior art, provides a kind of and gets the hollow blade in hole for soft material rule, and it is to adhesion when soft material boring or reaming, bore or expand the hole gauge come whole, without damaged.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of hollow blade getting hole for soft material rule, comprise handle of a knife, cutter hub and cutter head, handle of a knife is fixedly located at the front end of cutter hub, and cutter head is located at the rear end of cutter hub, and described cutter hub is the columnar structured of hollow, cutter hub open rearward end, be provided with the tapping channel be communicated with open rearward end in cutter head, cutter hub is provided with the clear material hole be communicated with tapping channel, and described cutter head is evenly provided with at least two along the rounded back end face of cutter hub.
Described handle of a knife, cutter hub and cutter head are processed one-body molded by medium carbon steel, be HRC40-45 through Quenching Treatment.
The cylinder of described handle of a knife to be external diameter be 6mm.
Described clear material hole is provided with two about cutter hub Central Symmetry, expects that clearly hole is the elongated hole arranged along cutter hub length direction for two.
Described cutter head is provided with four, the thickness of cutter head is identical with the wall thickness of cutter hub, each bit interface is made up of periphery, inner headed face, rear end face, trailing flank and leading flank, rear end face is connected with trailing flank and leading flank respectively, connecting line between rear end face and leading flank forms sharp sword, the angle of rear end face and cutter hub sagittal plane is 6 °, and the angle of trailing flank and cutter hub sagittal plane is 45 °, and the angle of leading flank and cutter hub sagittal plane is 37 °; Form the breach of a rear end opening between the leading flank of a cutter head and the trailing flank of an adjacent cutter head, breach reduces from front to back gradually, and the bottom of breach is arc-shaped structure.
Adopt technique scheme, handle of a knife adopts column structure, and during installation, throw can Automatic-clamping, and easily lays down, and does not need screw fixedly to screw.Cutter head of the present invention is evenly located on cutter hub rear end face, finally by two symmetries on cutter hub, can the exporting forward from the tapping channel in cutter hub of material when fraising or drilling operation, expects that clearly hole is discharged.
Cutter hub can be processed into different size and process the specification of different-diameter, different length.The hardness of cutter head and cutter hub is high, and wearability is good, long service life.Handle of a knife can install on the throw such as electric hand drill or air pressure gun.Cutter hub is according to removing clear material hole pore diameter size, the degree of depth difference of clout and processing different-diameter, length specification.
The above-mentioned specific structural features of cutter head is softer for quality specially material boring, fraising, makes the circular hole design of the regular all size of rule and the degree of depth, adhesion, bore or expand the hole gauge come whole, without damaged.
Structure of the present invention is simple, be easy to processing and manufacturing, lightweight, be convenient to discharge clout, reduce labor strength.Be specially adapted to the drain tube holes of the foaming box body such as refrigerator, refrigerator-freezer, showcase on household electric appliances streamline, evaporimeter outlet hole through hole or the regular making of blind hole, and the removing of foamed material in it, also can be used for other associated plastic, chemical industry.
