Abstract
The invention provides an alloy steel bit. The technical scheme includes that the alloy steel bit structurally comprises a bit body, main scrapers are transversely arranged on the front end face of the bit body, auxiliary scrapers are longitudinally arranged on the side wall of the bit body, the bit body is further provided with chip guide grooves, and a chip guide hole is arranged in the center of the bit body.
Description
Technical field
The present invention relates to a kind of alloy tool steel bit.
Background technology
On heavy castings, often have the slotted hole structure, this slotted hole needs molding sand is wherein cleaned out after casting is accomplished, and conventional now method for cleaning is to use long steel bar to be inserted in slotted hole inland river molding sand and discloses; But this method for cleaning is difficult to the molding sand in the slotted hole is cleaned out; And, in the process of disclosing, be difficult to hold the center of long steel bar; Very easily with the inwall scratch of slotted hole, even cause product rejection.
Summary of the invention
For solving above-mentioned technical problem, it is a kind of easy and simple to handle that the present invention provides, and is used to clear up the alloy tool steel bit of the interior molding sand of slotted hole on the foundry goods.
Technical scheme of the present invention is; A kind of alloy tool steel bit with following structure is provided; It comprises drill main body, and the front end face of drill main body is provided with the main scraper of lateral arrangement, and the sidewall of drill main body is provided with the auxilliary scraper of vertical layout; Also be provided with dregs guiding groove on the drill main body, the center of drill main body is provided with crump guiding hole.
After adopting said structure, the present invention has following remarkable advantage and beneficial effect:
When the slotted hole on the foundry goods was cleared up, drill bit was installed on the stock, and the rotation through main scraper scrapes molding sand; The effect of auxilliary scraper is that the inwall of slotted hole is cleared up, and the rotary speed of drill bit does not need very fast, can use manual rotation square steel yet; Operation is very easy; When cleaning, rectangular steel does not need in slotted hole, to move repeatedly, can avoid like this disclosing the inwall of slotted hole bad.
Preferable, main scraper and auxilliary scraper are one and are 90 ° of angles.Like this, be convenient to when slotted hole is cleared up, the cooperation between two scrapers, more clean to the cleaning of slotted hole.
Preferable, the afterbody of drill main body also is provided with and handles the location structure that stock is connected.Be convenient to the installation and the use of drill bit.
Preferable, described location structure is meant that the afterbody at drill main body is provided with square locating hole, this square locating hole and crump guiding hole connect.The dismounting of stock is all very easy.
Description of drawings:
Fig. 1 is the structural representation of alloy tool steel bit of the present invention;
Fig. 2 is the cutaway view of alloy tool steel bit of the present invention;
The specific embodiment:
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further.
Like Fig. 1, shown in Figure 2, alloy tool steel bit of the present invention, it comprises drill main body 1; The front end face of drill main body 1 is provided with the main scraper 2 of lateral arrangement; The sidewall of drill main body 1 is provided with the auxilliary scraper 3 of vertical layout, also is provided with dregs guiding groove 4 on the drill main body 1, and the center of drill main body 1 is provided with crump guiding hole 5.
Wherein, main scraper 2 all has 4 and evenly distribution with auxilliary scraper 3, and main scraper 2 is one and is 90 ° of angles with auxilliary scraper 3.
For ease of the dismounting of drill bit, the afterbody of drill main body 1 also is provided with and handles the location structure that stock is connected, and this location structure is meant that the afterbody at drill main body 1 is provided with square locating hole 6, and this square locating hole 6 connects with crump guiding hole 5.
