Embodiment 1

[0045] Such as figure 1 , figure 2 As shown, an alloy-inlaid dust-free rock wool cutting knife includes a knife body 1 and a blade 2, the knife body 1 is circular, the blade 2 is arc-shaped, and the blade 2 is connected to the outer surface of the knife body 1 in turn.

[0046] The blade 2 is arc-shaped segment by segment. Compared with the entire annular blade, the processing is more convenient. When die forging is used for processing, the size of the die is smaller. And when there is a gap in the blade 2, the section of the blade 2 at the gap can be removed, and a new blade 2 can be replaced, so that the whole cutter can be reused.

Embodiment 2

[0048] An alloy-inlaid dust-free rock wool cutting knife of this embodiment is similar to Embodiment 1, the difference is that this embodiment also includes a sound-absorbing groove 11, and the sound-absorbing groove 11 is evenly distributed on the knife body 1 and the blade 2, The sound-absorbing groove 11 runs through the cutter body 1 and the blade 2. The sound-absorbing groove 11 includes a central hole 113, a helical section 112 and a straight section 111. The helical section 112 connects the central hole 113 and the straight section 111 as a whole, and the central hole 113 and the helical section 112 Located on the cutter body 1 , the straight section 111 runs through the blade 2 and extends to the cutter body 1 .

[0049] In this embodiment, the straight line section 111 of the silencer groove 11 located on the blade 2 is located at the weld between two blades 2. Since the material of the weld is relatively soft, the processing is convenient, which further improves the p...

Embodiment 3

[0052] An alloy-inlaid dust-free rock wool cutting knife of this embodiment is similar to that of Embodiment 2, except that the knife body 2 also includes a shaft hole 12 and a connecting hole 13, and the shaft hole 12 is located at the bottom of the knife body 2. At the center of the circle, the connecting holes 13 are evenly distributed outside the shaft hole 12 , and the circle formed by the centers of all the connecting holes 13 is concentric with the shaft hole 12 .

[0053] In this embodiment, a shaft hole 12 is provided at the center of the cutter body 2 to facilitate the connection between the cutter and the power device, and the cutter can be quickly fixed on the power device through the connection hole 13, which improves the convenience of disassembly and assembly of the cutter.

Abstract

The present invention discloses a dust-free inserted carbide tool for cutting rock wool and a manufacturing method thereof, belongs to the technical field of mechanical tools, and aims at solving the problems of much dust and high machining noise when an existing tool for cutting rock wool is used to cut rock wool. A dust-free inserted carbide tool for cutting rock wool comprises a tool body and cutting edges. The tool body is circular, while the cutting edges are circular-arc-shaped; the cutting edges are uniformly welded on an outer side surface of the tool body to form a complete circumferential cutting edge; noise reduction slots are formed in an outer circular end of the tool body. The manufacturing method comprises: firstly, casting blanks of the tool body and the cutting edges, and carrying out semifinishing for the blank of the tool body; next, uniformly welding the blanks of the cutting edges on the outer side surface of the tool body; then, forming the noise reduction slots in the tool body; and finally, grinding the cutting edges welded on the outer circular surface of the tool body, thereby completing the production of the tool. The dust-free inserted carbide tool for cutting rock wool has complete cutting edge circumference without sawtooth gap, and therefore, very little dust may be produced when a rock wool board is cut; and the noise reduction slots in the cutter body may well reduce the machining noise.

Description

technical field [0001] The invention belongs to the technical field of mechanical knives, and more specifically relates to an alloy-embedded dust-free rock wool cutting knife and a processing method thereof. Background technique [0002] Rock wool is a kind of thermal insulation, heat insulation and sound insulation material. Because of its superior energy saving, fire prevention, sound insulation, environmental protection, non-corrosion, and non-radioactive properties, it is widely used in thermal insulation and fire prevention in industries and buildings. When cutting rock wool, if the cutting tool is not selected properly, it will lead to swelling, falling apart, uneven surface or warping around the cut rock wool, which will affect the use of rock wool. At present, the cutting knives equipped with rock wool production equipment generally use saw blades with serrations. Because the thickness of the saw teeth is relatively thick, there are serrated gaps in the blade part, a...
