Abstract

The utility model relates to a novel radiating tool bit saw blade, which comprises a circular or arc metal saw blade body, wherein a plurality of saw tooth tool bits are welded along an outer arc of the saw body; side faces of the saw tooth tool bits have a plurality of planar connection shapes; the lateral projection of the side faces is reduced from the front to the rear; and more than or equal to two side faces are formed. By the novel radiating tool bit saw blade, the cutting heat generated by the friction of the side faces of the tool bits in the cutting process is greatly reduced, and due to the special tool bit structure, the radiating capacity of the saw tooth tool bits is improved; and moreover, the actual cutting area of the tool bits is small, the resistance is reduced, and the cutting is facilitated, so that the cutting stability of the body under high-speed operation is kept, the cutting quality is improved, and the machining environment is improved.

Description

A kind of heat sinking cutter head saw blade

Technical field

The utility model relates to a kind of saw blade, is specially adapted to cut the carbon steel metalloid material.

Background technology

Along with rapid development of national economy, automobile and aerospace industry have obtained development at full speed, as the important tool in the metal material processing---and high-accuracy metal cutting tool market capacity has also obtained swift and violent lifting.

The common metal saw blade is when carbon steel; Cutter head side and a large amount of heat in metal cutting of material cut face friction generates, blade body material receive under the effect of complicated power of centrifugal force, residual stress, thermal stress and cutting stress etc., take place vertically, laterally and twisting vibration; Make saw body outer edge portion produce into distortion such as scalloped shape; And occur big such as the teeter amount, bad phenomenon such as machining accuracy is low, and work noise is big.

Summary of the invention

The utility model will overcome the big shortcoming of existing metal purposes saw blade cutting frictional heating amount, the low saw blade of frictional heat when a kind of sawing is provided.

Heat sinking cutter head saw blade; The metal saw blade saw body that comprises circle or circular arc; Weld a plurality of saw-tooth tool bits along described saw body external arc; It is characterized in that: the side of described saw-tooth tool bit is the shape that a plurality of planes connect, and the side direction protrusion amount of said side reduces said side quantity >=2 after by forward direction.

Further, the side of described saw-tooth tool bit is formed by connecting major opposing side 2g and drag reduction heat radiation side 2f, and described drag reduction heat radiation side 2f is connected the rear of described major opposing side 2g, and the side direction protrusion amount of described drag reduction heat radiation side 2f reduces after by forward direction.

Common metal purposes saw blade adds man-hour at the high speed rotary cutting, and the whole cutter head side and the material cut face of saw-tooth tool bit rub, and heat is constantly to the saw body back of tooth and the conduction of saw body; Saw receives the heat in metal cutting stress influence again when receiving complicated cutting force, make to make the distortion of saw body generation patellate the saw body produce end face run-out perpendicular to thickness direction and sharply become big; Make cutting unstable; The cut quality variation produces vibrating noise simultaneously, finally causes sawing body distortion severity.

At least one side, two sides of the cutter head of the utility model is many side views, and the side view of the saw-tooth tool bit two sides of the utility model is symmetry or asymmetric distribution.

During saw blade high speed rotary cutting, novel saw-tooth tool bit only cutter head major opposing side is participated in the friction cutting, and because of the cut surface area reduces greatly, resistance has obtained effectively reducing, and cuts more brisk; On the other hand; Cutter head drag reduction heat radiation side is because outstanding saw body side height＜cutter head major opposing side; Make cutter head drag reduction heat radiation side not participate in cutting; Therefore in working angles, play good ventilation and heat effect, reduce heat and cause sawing the thermal deformation of experiencing, thereby make cut quality under the not serious situation of corner wear degree, can keep stable always toward the saw body.Make the duty of saw blade more stable, noise is reduced effectively.

The characteristics and the effect of the utility model are: compare with traditional saw blade, cut more briskly, heat in metal cutting is lower, has more effectively lowly reduced noise, has improved cutting quality, has improved production environment.

The specific embodiment

Below in conjunction with instance and accompanying drawing the utility model is done further explanation.

Embodiment one

With reference to accompanying

drawing

1,2,3:

1a-saws body; The 1b-saw body back of tooth; The 2-saw-tooth tool bit; 2a-rake face (cutting face); 2b-rake face (clearance surface); Replace chip-breaker about 2c-; Knife face behind the 2d-; The 2e-radiating surface; 2f-drag reduction heat radiation side; 2g-major opposing side; Chip pocket at the bottom of 3-tooth; 4-endoporus (centre bore)

The novel saw-tooth tool bit saw blade; Comprise metal saw blade saw body 1a, inlay a plurality of saw-tooth tool bits 2 along described saw body 1a cylindrical, the side of described saw-tooth tool bit is the shape that a plurality of planes connect; The side direction protrusion amount of said side reduces said side quantity >=2 after by forward direction.

In the present embodiment; The side of described saw-tooth tool bit is formed by connecting major opposing side 2g and drag reduction heat radiation side 2f; Described drag reduction heat radiation side 2f is connected the rear of described major opposing side 2g, and the side direction protrusion amount of described drag reduction heat radiation side 2f reduces after by forward direction.

Many side views of described saw-tooth tool bit 2 two sides are symmetry or asymmetric distribution.

Described saw body 1a is installed on the equipment mandrel through endoporus 4.Saw-tooth tool bit 2 is embedded on the saw body back of tooth 1b.

Common saw blade adds man-hour at the high speed rotary cutting, and the whole cutter head side and the material cut face of saw-tooth tool bit rub, and heat is constantly to the saw body back of tooth and the conduction of saw body; Saw receives the heat in metal cutting stress influence again when receiving complicated cutting force; Make to make the distortion of saw body generation patellate the saw body produce end face run-out and sharply become big, make cutting unstable perpendicular to thickness direction; The cut quality variation produces vibrating noise simultaneously.

The saw-tooth tool bit side of the utility model is many side views, and described side overhang reduces after by forward direction, described side quantity >=2, and many side views of two sides are symmetry or asymmetric distribution.

During saw blade high speed rotary cutting, saw-tooth tool bit only cutter head major opposing side 2g is participated in the friction cutting, and because of the cut surface area reduces greatly, resistance has obtained effectively reducing, and cuts more brisk; Cutter head drag reduction heat radiation side is because outstanding saw body side height＜cutter head major opposing side; Make cutter head drag reduction heat radiation side not participate in cutting; Therefore in working angles, play good ventilation and heat effect; Reduce heat and cause sawing the thermal deformation of experiencing, thereby make cut quality under the not serious situation of corner wear degree, can keep stable always toward the saw body.Make the duty of saw blade more stable, noise is reduced effectively.

Embodiment two
