Abstract

The utility model relates to an electroplating diamond thin-wall toothed drill bit which comprises a base body of the drill bit, one end of the base body of the drill bit is provided with a clamping handle, the other end of the base body of the drill bit is provided with a drilling body, water inlet holes are arranged on the thin wall of the drilling body and the front end of the drilling body is a cutting edge. Differently, concave-convex designs which are molded by mechanical extrusion are arranged on the peripheral thin wall of the cutting edge, and the concave-convex designs are arrayed into an acute angle in a reverse connecting mode around the peripheral thin wall of the cutting edge. The concave sections vertically fall from the top end of the cutting edge, the concave depth is less than or equal to two-thirds of the depth of the thin wall of the drilling body, the convex sections form a tooth shape on the end of the cutting edge, the top of the tooth forms an irregular arc shape, a tooth-shaped cutting edge is formed from the tooth and the concave-convex designs, and carborundum is electroplated on the thin wall of the tooth-shaped cutting edge. When the utility model processes a drilling hole, the utility model has no need to be arduously extruded, and the utility model has the advantages of quick drilling speed, strong abrasive resistance, high efficiency for drilling a hole, good quality and long service life, and is suitable for the further processing of various materials, such as glass, stone, etc.

Description

Electroplated diamond thin-walled indented chisel

(1) technical field:

The utility model relates to the processing drilling machine, particularly a kind of electroplated diamond thin-walled indented chisel.

(2) background technology:

Be generally used for the electroplated diamond bit of glass deep processing and processing of stone, its cutting edge is horizontal line shape, decorative pattern on the thin-walled of cutting edge one side is the perpendicular parallel lines of uniform shallow trace, only play the small bits effect that goes out, not only the diamond that adheres on the cutting edge is few, and in fact the diamond on the parallel decorative pattern does not play the effect that help is crept into.Therefore, when creeping into, not only speed is slow, and work efficiency is low, output is few, processing work easily breaks, and the diamond on the parallel decorative pattern becomes unnecessaryly because of not bringing into play the effect of creeping into, and is worn very soon, wasted, drill bit is easily blunt, and service life is short, has also caused drill bit to use the increase of the loss amount of steel material simultaneously.

(3) utility model content:

The purpose of this utility model is exactly will a kind of drilling efficiency height, converted products quality are good, the electroplated diamond thin-walled indented chisel of long service life for the public provides.

The utility model comprises bit matrix, one termination of bit matrix is a clamp holder, another termination is a drill body, the drill body thin-walled is provided with the inlet opening, the front end of drill body is a cutting edge, the periphery thin-walled of different is cutting edge is provided with the ridge design that the mechanical presses moulding is arranged in order, described ridge design is the acute angle reverse graft around cutting edge periphery thin-walled and arranges, flat edge top, recessed position head vertically descends, protrude the position and form dentation in the cutting edge termination, the top of tooth is irregular arc, and tooth and ridge design form the dentation cutting edge, are coated with diamond dust on dentation cutting edge thin-walled.

The recessed degree of depth of ridge design is smaller or equal to 2/3 of the drill body thin-walled degree of depth on the described dentation cutting edge.

The utility model electroplated diamond thin-walled indented chisel is set as the dentation cutting edge of being with ridge design at bit matrix top cutting edge, and following advantage is arranged:

1, whole drill bit, the projection of ridge design also just is equivalent to a spark on the dentation cutting edge, connect together but be one independently whole, when creeping into, the extruding of need not requiring great effort, proper as long as weight is held, boring is justified and is not split, positive back side unanimity, and product quality is fully ensured;

2, the recessed degree of depth of drill bit dentation cutting edge ridge design is smaller or equal to 2/3 of walled thickness, concave, convex partly becomes the state of tearing by inches, diamond dust is fully attached easily firmly, strengthened the top power of creeping into, the top of dentation cutting edge tooth is irregular arc, also increased the fixed area of diamond dust and strengthened the hardness of tooth, thereby increased the scuff resistance of electroplated diamond thin-walled indented chisel and crept into strength;

3, the ridge design on the dentation cutting edge, when creeping into, after the tooth of cutting edge front end wears down, the diamond dust that the recess of cutting edge thin-walled adheres to begins to play a role, because the decorative pattern recess on the thin-walled is thinner than dentation cutting edge, the diamond dust of filling is more, it is more firm to adhere to, at this moment creep into appearance thin more with cutting edge more continuously, hard more whetstone, rate of penetration is fast more, short more phenomenon consuming time;

4, this new drill is because above structural design is ingenious, the tooth on cutting edge thin-walled top, ridge design and plating diamond dust thereon can be slowly continuous, orderly common consumption, diamond dust can not occur is worn earlier, and the very fast rust of cutting edge and the situation that can't use, thereby the work efficiency of this novel electroplated diamond thin-walled indented chisel and wearability are strengthened, prolonged service life greatly.

(4) description of drawings:

Fig. 1 is an overall structure schematic diagram of the present utility model;

Fig. 2 is a bit matrix structural representation of the present utility model.

(5) specific embodiment:

The utility model bit matrix is a hollow cylindrical shell, select for use 45# high-quality steel to process, the one end is clamp holder (1), the other end is drill body (2), the interior open circles coaxial inner conductor of clamp holder (1) and drill body (2), diameter is less than drill body (2) diameter, on drill body (2) thin-walled, be provided with inlet opening (3), drill body (2) walled thickness is 0.25mm-0.6mm, the front end of drill body (2) is a cutting edge, on the periphery thin-walled of cutting edge by special special equipment repeatedly embossing form the ridge design (4) that the acute angle reverse graft is arranged in order, protrude the position and form tooth (4-1) in the cutting edge termination, the top of tooth (4-1) is irregular arc, flat edge top, recessed position (4-2) head vertically descends, the recessed degree of depth is smaller or equal to 2/3 of the drill body thin-walled degree of depth, and tooth (4-1) and ridge design (4) form dentation cutting edge (5), promptly finish the processing of bit matrix, through electroplating technology processing, plated with gold emery (6) gets final product on dentation cutting edge (5) thin-walled of drill body (2) again.

This novel ridge design (4) not necessarily is the ridge design that acute angle is arranged in order, also the concavo-convex decorative pattern of other shape.

This new drill is by practice, compare with general drill bit processing same size, the glassy phase of thickness: general drill bit can only bore the 20-30 hole, cutting edge can't use with regard to rust, and electroplated diamond thin-walled indented chisel of the present utility model, existing minimumly reach 200-300, and the positive back side, the hole unanimity of processing brill, quality is good, and the processed glass fracture phenomena can not occur.According to the difference of rapidoprint in the middle of using, the product of this novel all size that is designed to vary in size.
