For metal cutting diamond saw blade

(-) Technical Field:

[0001] The invention relates to cutting tools, in particular to a diamond for metal cutting blade.

(B) Background Art:

[0002] diamond saw blade is widely used in geology, water conservancy, energy, construction, transportation and other industries and sectors. Diamond circular saw sheet structure, mainly composed of two parts: a base body and head. Head substrate is bonded portion of the main support, the head is in the course of the part from the cut. Work with diamond blade including without diamond layer and laminated plus non-working together, heads of non-diamond portion is called the carcass.

[0003] When the cutting blade iron castings and bar, pipe and other metal products, due to the high hardness of the workpiece, and has a certain toughness, head carcass cutting the workpiece at an impact speed, the resulting stress to deform the substrate, cause significant vibration, the blade cutting path generates the actual yaw, resulting in a large number of invalid cutting, sawing reduced stability, which in turn exacerbate diamond saw blade working body heat, causing the diamond burned, blade failure, the efficiency dropped significantly, to extend working time. And because the substrate vibrations produced a lateral force on the head, causing head fracture, causing an accident.

(Three) utility model content:

[0004] For the traditional shortcomings of diamond saw blades, the utility model is intended to propose a suitable metal cutting diamond saw blades, diamond saw blades in order to solve the existing cutting metal substrate to produce vibration, cutting poor stability issue.

[0005] The above object can be achieved for metal cutting diamond saw blade, comprising a substrate on the substrate and the consolidation of a number of heads, the difference is that the stress on the substrate is provided with grooves, the stress in phase as a starting slot o chute at the head gap, the oblique rotation the blade in the same work, the stress point of the groove and the stress in radial groove 40 degrees to 45 degree angle; said substrate also is provided with circumferentially evenly distributed multi-set of enhancements Kong, the enhancement holes from each end of the stress groove extending along the line toward the slot arrangement stress.

[0006] said substrate is formed with grooves and stress enhancement holes, dispersed metal cutting blade stress generated by the impact, reducing the deformation of the matrix, the matrix to reduce the vibration amplitude, reducing the ineffective cutting, improved blade cutting efficiency, significantly reducing construction period, reduce costs, improve production safety.

[0007] According to different sizes of blades, the stress in the length of the slot to choose between 12mm ~ 15mm, width 2mm ~ 4mm choose between.

[0008] Preferably the stress length of the groove 14mm, preferably a width of 3mm.

[0009] wherein each enhancement holes arranged in a manner arranged by involute, said involute starting at the center and finally the stress matrix groove ends.

[0010] Typically said enhancement holes to 4 groups, each enhancement holes in an amount of 5 to 8.

[0011] The preferred amount of each enhancement holes 6.

[0012] According to different sizes of saw blade, the hole diameter of the reinforcing C> 4mm ~ C> 6mm choose between.

[0013] Preferably the reinforcing hole diameter 0 5. 5mm.

[0014] The utility model has the advantages of: [0015] I, the utility model for metal cutting diamond saw blade diamond saw blade, compared with the traditional, the stress due to the opening slot and enhanced hole reduces blade at work vibration, cutting efficiency increases 0. 5 ~ I times, greatly improving the efficiency of cutting metal, significantly reduced time, reduced costs, improved security.

[0016] 2, the utility model for metal cutting diamond saw blade with reasonable design, simple structure, after the drill several times to increase the efficiency and lifetime, high efficiency, and low cost.

(Four) Brief Description:

[0017] Figure I an embodiment of the utility model the structure of Fig.

[0018] Figure No. ID: 1, head; 2 matrix; 3, stress grooves; 4, reinforced holes.

(Five) Specific embodiments: [0019] The following combination of drawings, the present utility model technical solutions for further explanation:

[0020] The present invention is suitable for metal cutting diamond saw blade by a number of I and the substrate 2 is configured, the uniformity of the welding head with a diameter of I O336mm the circumference of the base body 2, as shown in Figure I.

[0021] The base body 2 is provided with a groove 3 and the enhancement holes stress 4.

[0022] Since the stress adjacent the head tank 3 at the gap as a starting point I of the base body 2 of the chute opening, the stress of the oblique grooves 3 are identical and the same direction of rotation of the diamond blade, slot 3 of the stress I and the corresponding head adjacent the radial clearance into an angle of 40 degrees to 45 degrees (with the blade can also be described as a rotational tangential normal angle of 40 degrees to 45 degrees), preferably 42 degree angle, slot 3 in the longitudinal stress of 12mm ~ 15mm, preferably a length of 14mm, a width of 2mm ~ 4mm, preferably a width of 3mm, as shown in Figure I.

[0023] The enhancement holes 4 are designed to evenly arranged circumferentially of the four groups, each enhancement holes 4 in an amount of 5 to 8, preferably 6, to enhance the diameter of holes 4 O 4mm ~ O 6mm, preferably 0 5 . 5mm, each enhancement holes 4 from tank 3 to the stress along the corresponding end of the extension line of the involute arrangement, the involute from the center of the base 2 and ends with the end of the stress tank 3, as shown in Figure I shown.

[0024] This embodiment of the utility model is not exhaustive, the stress slot 3 width, length and angle, the diameter of the reinforcing hole 4, the number, arrangement can be based on the substrate material, structure type, or cutting conditions such as rotational speed varies with different designs.
