Abstract

Device for cooling bits, which being intended to cool bits in order to avoid heating them as far as possible, is characterized in that it comprises a main body (1) that incorporates an internal compartment (2) containing a coolant liquid, which communicates to the outside through a passage where a bit portion (6) is located during the drilling operation of a part (8), so that at least a flat portion of one face of the main body (1) where the drill bit (6) appears, said flat portion sits on the surface to be drilled of the respective piece (8).

Description

Device for cooling drills.

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a device to cool drill bits that aims to cool drill bits, essentially when working hard materials, as per example porcelain materials, in which the drill suffers a high wear

Background of the invention

Currently, within the methods and devices used for drill cooling usually resort to devices that print a water jet or any  other coolant on the cutting tool or drill to decrease its temperature. This way of reducing the temperature has the disadvantage of needing a system of impulsion of this fluid impacting on the cost of carrying out the operation, not being profitable when a use is made particular.

Another of the known systems is based on drill bits with channels for refrigerants, (Invention Patent with number of publication 2123752) however, the manufacturing cost of This type of drill does not make it viable for a particular use or domestic.

Description of the invention

In order to achieve the objectives and avoid the drawbacks mentioned in the previous sections, the invention proposes a device for cooling bits that are characterized because it is determined from a main body, essentially prismatic-rectangular, which is of sufficient dimensions to be able to hold it by hand while drilling operation is performed. It is constructed of a material that allows to obtain smooth faces or at least one smooth face that will coincide with the one that will rest on the surface of the piece pierce, since what is intended is that said face make a Approximately tight seal with the surface to be drilled. Obviously the main body may present any other different configuration.

The device will have a compartment hollow inside that will be filled with the corresponding coolant

This compartment will be available in one of its ends of two openings communicated with each other and each of the which will lead to the respective face of the prism that will pass through the drill bit precisely in correspondence with said openings.

The opening facing the surface to drill will be large enough to cover the area of drilling, allow the extraction of dust from the drilling and have releases, at all times, the drill bit and the coolant This opening can be surrounded by a joint toric or similar, which helps to achieve tightness wanted.

Instead, the other even opening, implemented on the face of the opposite prism, it will adjust approximately to the bit size, being able to have some system of bearings, which avoid friction between the drill and the walls of said opening.

To use the device it will be filled the internal compartment with a coolant, leaning then on the surface to practice the drill with the face that it has the largest opening and, it will be pressed against said surface, for later, introduce the drill bit through the openings and perform the corresponding drilling. In cases where the drilling hole is practiced on surfaces vertical, the device will then rest on the surface to drill with the prism body facing the ground, to do not spill the coolant and once the pressure on the device and inserted the drill bit, will be rotated 180º in order to that the coolant falls on the drill without spill.

Next to facilitate a better understanding of this descriptive report and being an integral part of the same accompany some figures in which with character illustrative and not limiting the object of the invention.

Brief description of the drawings

Figure 1.- Shows an elevation view of the Drill cooling device, object of the invention.

Figure 2.- Shows a profile view of the device of the invention.

Figure 3.- Shows a view of the application Of the device.

Description of the preferred embodiment

Considering the numbering adopted in the figures, the device for cooling bits is determined to start from a main body with a configuration prismatic-rectangular 1 that incorporates a internal compartment 2 that communicates to the outside through two openings facing opposite faces and coinciding with drilling hole direction: a front opening of larger size 3 and a later one of smaller size 4 adapted to drill diameter 6. Obviously in said compartment internal 2 the coolant will be located to cool the drill during your drilling job.

The major opening 3 has dimensions enough to cover the drilling hole 7 and also the surrounding area where dust and chips remain extracted in the drilling operation.

The realization of the main body 1 will allow that at least the face resting on the surface of the piece to drilling 8 will preferably be smooth, at least in the area where find the major opening 3, which will obviously be located in That smooth face.

On the other hand, the edge or perimeter zone that surrounding the major opening 3 may incorporate an o-ring 5 or another type, which facilitates the tightness between the device of the invention and the free surface of the piece 8 to be drilled.

The joint will fit in a groove Complementary ring configuration 9.

Instead, the other minor couple opening size 4 has enough dimensions to fit approximately to the diameter of the drill 6 and whose walls can there are elements that prevent friction with adequate means, such as bearings or others.
