Manufacturing method of diamond saw chain

Abstract

The invention relates to the field of diamond cutting tools, in particular to a manufacturing method of a diamond saw chain. The diamond saw chain mounted on a chain saw cutter of reinforced concrete is used for cutting building materials, such as the reinforced concrete and bricks. The diamond saw chain is made by riveting a plurality of chain link units. Each chain link unit comprises a tooth plate I, a diamond bit, a tooth plate II, a connecting plate and a pin, the diamond bit is provided with a steel core, and both the tooth plate I and the tooth plate II are provided with protective teeth. A bit die is made of graphite and used for manufacturing the diamond bits. The manufacturing method is suitable for manufacturing the diamond saw chain; welding cost is low, welding strength is high, and cutting performance can be improved; the tooth plate I and the tooth plate II with the protective teeth protect the diamond bits from high impact load during operating, and the service lives of the diamond bits are prolonged.

Description

technical field [0001] The invention relates to the field of diamond cutting tools, in particular to a method for manufacturing a diamond saw chain for manufacturing a diamond saw chain. Background technique [0002] Reinforced concrete chainsaw cutting machine can effectively cut reinforced concrete, bricks, stone, coal seam, granite, marble and other building materials, and can carry out on-site operations such as building emergency rescue, fire rescue, wall opening, cement pipe cutting, house renovation, ground finishing, etc. , can cut corners without overcutting, can perform deep cutting, sharp corner cutting, irregular shape cutting, small vibration during cutting, small and compact machine, convenient to work in a small space, and can effectively avoid (or reduce) the accident of rescue personnel It is an ideal professional cutting tool. [0003] The cutting efficiency and use cost of the reinforced concrete chainsaw cutting machine mainly depend on the matching diam...

Problems solved by technology

[0003] The cutting efficiency and use cost of the reinforced concrete chainsaw cutting machine mainly depend on the matching diamond saw chain. Since the reinforced concrete chainsaw cutting machine is mostly hand-held operation, the machine is easy to shake and feed unevenly during cutting, and the diamond saw chain The speed changes greatly, the load impact is large, and most of the operations are in narrow or special spaces. Generally, the time requirements are very tight, etc. Therefore, higher requirements are put forward for the cutting efficiency of the diamond saw chain and the strength of the diamond head.

In the manufacturing process of the current diamond saw chain, the diamond cutter head is directly welded on the substrate by laser welding, so there are at least the following two problems: one is the high price of the laser welding machine, and the welding cost is high; the other is that the cutter head and the substrate It is impossible to match completely, and it is even more impossible to be completely consistent. This will not only affect the welding quality and strength, but also affect the shape and surface properties of the weld. Materials that are not necessarily conducive to improving the cutting performance of the bit, thereby increasing the cost of the bit and possibly adversely affecting the cutting performance of the bit
