Abstract

The invention aims to provide a straight fluted drill, which is long in service life so that production cost is reduced. The straight fluted drill comprises a handle and an edge, a side edge and a chip flute are axially arranged at the edge, and pivotally, a platform is arranged at the bottom of the chip flute. By the aid of the special fluted design, on the premise of ensuring a large core thickness, more chip containing spaces are available, double edges formed by the platform are fine in guidance, and the quality of a machined product can be ensured more effectively. The straight fluted drill is ingenious in structural design, large in core thickness, large in chip containing space and fine in guidance, and a drill bit cannot break, so that production cost is reduced.

Description

A kind of straight-flute drill
Technical field
The invention belongs to cutter manufacturing technology field, specially refer to a kind of straight-flute drill.
Background technology
Drill bit with an important component part in the cutter, is mainly used in the roughing in hole as machining.Along with the development of mechanical industry, the user is to having proposed requirements at the higher level delivery date of the crudy of product, process reliability, working (machining) efficiency, cutter etc.Traditional straight-flute drill grooved angle is generally 90 °, and chip space is little.Adding man-hour, the contact area of its front end and workpiece is big, and drill bit ruptures when receiving the resistance of unexpected increase easily, and working (machining) efficiency and crudy are caused negative effect, therefore can increase processing cost.
Summary of the invention
The objective of the invention is to propose a kind of straight-flute drill of long service life, to reduce production costs.
Straight-flute drill of the present invention comprises shank and blade, and said blade is along himself being axially arranged with side edge and chip pocket, and key is that the bottom land of said chip pocket is provided with platform.The special grooved design of this kind is guaranteeing under the thick prerequisite of big core more chip space is arranged, and formed pair of seamed edge of platform has good guidance quality simultaneously, more can guarantee the quality of product to be processed.
Further, the grooved angle of said chip pocket is 105 °, and the tapering of the thick positive cone of core of straight-flute drill is 1:16, is drilled with the thick and more chip space of bigger core to guarantee straight trough.
Further, two straight in cold hole cooperate the type of cooling of gathering sill structure, improved working (machining) efficiency greatly, be both cutter and workpiece cooled off.Make cutter have higher life-span workpiece that better quality is arranged.
Straight-flute drill structural design of the present invention is ingenious, and big core is thick and chip space is big, and guidance quality is good, guarantees that drill bit can not rupture, thereby reduces production costs.
Description of drawings
Fig. 1 is the structural representation of straight-flute drill of the present invention.
Fig. 2 is the head end structural representation of straight-flute drill of the present invention.
The specific embodiment
Contrast accompanying drawing below; Through the description to embodiment, the effect of mutual alignment between the shape of specific embodiments of the invention such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are done further to specify.
Embodiment 1:
As shown in Figure 1, the straight-flute drill shank 2 and the blade 1 of present embodiment, blade 1 is along himself being axially arranged with side edge 3 and chip pocket 4, and the bottom land of chip pocket 4 is provided with platform 5.The special grooved design of this kind is guaranteeing under the thick prerequisite of big core more chip space is arranged, and formed pair of seamed edge of platform has good guidance quality simultaneously, more can guarantee the quality of product to be processed.
The grooved angle of chip pocket 4 is 105 °, and the tapering of the thick positive cone of core of straight-flute drill is 1:16, is drilled with the thick and more chip space of bigger core to guarantee straight trough.
This special structural design improve greatly working (machining) efficiency, cutter also has the higher life-span.Further practiced thrift production cost.
