Abstract
The utility model relates to a cutting tool used on a milling cutting device, in particular to a hard alloy saw blade milling cutter used in cutting pipes and comprises a saw blade body and saw teeth; wherein, the saw blade body is a disc made of alloy tool steel with a hole in the center; a rectangular keyway transferring torques is processed at the periphery of the central hole of the disc, and the saw teeth made of P40 hard alloy is connected with the external circumference of the saw blade body by means of the AG welding; edge parts of the saw teeth can be front angles, back angles, inclination angles and chip breakers. Used on the same milling cutting device, the cutting tool of the utility model can satisfy the processing requirements of cutting the oblique mouths of the steel pipe of Phi 80*5mm in 100s as well as improving the cutting speed greatly and increasing the feed speed correspondently. By adopting the P40 hard alloy cutter teeth material suitable for interrupted and heavy loaded cutting, the saw blade not only reduces the phenomenon of tooth beating and tipping, but also improves the continuous service life for more than 300 times, so the cutting tool can replace the traditional high speed tool steel milling cutters and greatly improve the utilization effect.
Description
Technical field:
The utility model relates to the parting tool that uses on the milling equipment, especially a kind of Pipe Cutting carbide alloy metal saw.
Background technology:
In the milling cutting-off process of steel pipe, workpiece is to be under the room temperature state, and common used material is the above steel grade of moderate strength.Under normal conditions, the user generally uses universal machine tools or the special milling equipment of making to process, and the processing conditions majority belongs to be done cutting or apply a spot of oil lubrication, and traditional machining tool is the high-speed tool steel metal saw, and flute profile is common sawtooth pattern.
Because the hardness of high-speed tool steel is lower, wearability, hear resistance are also poor, therefore are easy to produce wearing and tearing, passivation in milling during high-intensity tube material.Simultaneously high-speed steel its fragility when the above hardness of HRC63 is apparent in view, in the milling process, occurs tipping easily, plays unusual damage such as tooth, has seriously influenced its service life.With Φ 320 * 5 * 90 rack saw slitting milling cutters is example, its cutting speed commonly used is 20-40m/min, when the automobile steel pipe of milling Φ 80 * 5mm, otch is 20 ° a angle, strengthened milling area and stroke, factory requires every 100s to finish-individual milling circulation, can satisfy the operation rhythm of production line, and the fastest milling cycle period of cutting speed that adopts v=40m/min when using the HSS sawblade milling cutter is also about 185s, and can only cut off tens mouthfuls and just cause milling cutter to damage.
Summary of the invention:
The utility model is intended to solve defectives such as the working (machining) efficiency that has the metal saw existence now is low, the life-span is short, make by Hardmetal materials and provide a kind of body to adopt alloy tool steel to process, saw sword, has good mechanical properties, the Pipe Cutting carbide alloy metal saw that can increase the service life.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of Pipe Cutting carbide alloy metal saw, comprise blade body, sawtooth, blade body is the center disk with holes that alloy tool steel is made, disc centre hole periphery is processed with the rectangle keyway that transmits moment of torsion, the sawtooth of being made by the P40 carbide alloy is connected with the blade body excircle by the silver soldering mode, and this sawtooth blade is processed with anterior angle, relief angle, cutting edge inclination, chip-breaker.
Compared with prior art, the beneficial effects of the utility model are: be used on the same milling device, cutting speed can be increased substantially to 80-100m/min, after the corresponding increase feed speed, the processing request of Φ 80 * 5mm steel pipe angle of in the time of 100s, cutting sth. askew can be satisfied.Be suitable for P40 carbide cutter tool teeth material interrupted, the heavy duty cutting owing to adopt, saw blade not only reduced beat tooth tipping phenomenon, and along with the raising of Hardmetal materials hardness, wearability, bring up to more than 300 times its continuous service life.Therefore the utility model can replace traditional high-speed tool steel milling cutter, significantly improves result of use.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 looks intention for broached-tooth design master of the present utility model.
Fig. 4 is the left view of Fig. 3.
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples:
A kind of Pipe Cutting carbide alloy metal saw, constitute by blade body 1, sawtooth 2, blade body 1 structure in the form of annular discs, make by alloy tool steel, have centre bore 3, centre bore 3 monolateral or twoly be processed with several and transmit the rectangle keyway 4 that moments of torsion are used, sawtooth 2 is made by the P40 carbide alloy, sawtooth 2 is connected with blade body 1 excircle by the silver soldering mode, and these sawtooth 2 blades are processed with chip-breaker 5, anterior angle 6, relief angle 7, cutting edge inclination 8, have made it to have very high shearing strength.
Metal saw of the present utility model can be installed on the universal or special milling equipment and use, after milling cutter is installed on the mechanical main shaft securely, can adjust rotary speed, feed speed, advancing and retreat to cut off by front and back is clamped in the various steel pipes of stablizing in the clamping device, can obtain vertical incision or skew back otch.The feeding mode of milling cutter generally is the horizontal sliding mode.
Claims (1)
