1, during the shank collar forging and molding of taper drill steel; Need forge the position to the taper drill steel and carry out the shank collar that in forging die, is shaped after the intermediate frequency spot heating; This local Forge Heating makes the taper drill steel body of rod stand once to add the thermosetting heat affected zone to cause the body of rod tissue odds of taper drill steel even more; If the elimination heat affected zone has increased manufacturing cost; The present domestic heat affected zone of not eliminating basically, therefore, the application life that the technology of forging corselet has reduced the taper drill steel.
2, during the shank collar moulding be forging and molding on the raw material cored steel basis of taper drill steel; Therefore; When forging shank collar deformation, be prone to form wedge angle, folding, defective such as " horn mouth ", thereby cause the distortion of shank collar part endoporus, the shank collar water hole is too small or block at the shank collar endoporus.
Owing to have above-mentioned shortcoming, when adopting existing method to forge shank collar, tend to cause taper drill steel initial failure ratio very big.Therefore, use the method for forging the shank collar of making the taper drill steel very undesirable, can not satisfy the needs of use.
Summary of the invention
The purpose of the utility model is: provide that a kind of manufacture craft is simple, easy to operate, production efficiency and yield rate is high, the taper drill steel of long service life, to overcome the deficiency of prior art.
The utility model is achieved in that a kind of taper drill steel of the utility model does, this taper drill steel comprises the taper drill steel that is not manufactured with shank collar, be not manufactured with the shank collar that is fixed with employing plastics or elastomeric material making on the taper drill steel of shank collar.
On the external surface of the shank collar of plastics on the taper drill steel or elastomeric material, also be with the steel pipe that thickness is 1mm～8mm in said fixing.
The external surface shape of above-mentioned shank collar is cylindrical shape or is the polygon cylindrical shape.
The polygon cylindrical shape of above-mentioned shank collar is the shape of quadrangle cylinder, regular hexagon cylinder, octagon cylinder or dodecagon cylinder.
The length of above-mentioned shank collar is respectively 10～30 millimeters, 30～60 millimeters, 60～90 millimeters, 90～120 millimeters, 120～150 millimeters or 150～200 millimeters.
Owing to adopted technique scheme, the utility model on the taper drill steel of making, to adopt plastics or elastomeric material to produce shank collar again, and the shank collar of plastics or elastomeric material be fixed on the drill steel to replace the effect of traditional shank collar.Can make drill steel like this after carrying out conventional heat treatment; Carry out the manufacturing of shank collar at normal temperatures; The stability and the uniformity of the tissue of drill steel have been guaranteed effectively, the drill steel initial failure that makes drill steel avoid drill steel to cause, thereby application life of having improved the taper drill steel greatly because of the inefficacy of shank collar.And; The plastics that the utility model adopted or the shank collar of elastomeric material can be changed it after in a single day losing efficacy at an easy rate, thereby greatly reduced the use cost of drill steel; Make its raw-material availability improve 50%～70%, the production qualification rate can reach more than 99%.Therefore; The utility model compared with prior art; The utility model has not only that manufacture craft is simple, production efficiency and yield rate is high, the advantage of long service life, but also have process operation convenient, and can on used taper drill steel, change advantage such as shank collar easily more again.
