Description
Technical field:
The present invention relates to a kind of diamond saw cutting tool, the chain that particularly a kind of diamond chain saw is used.
Background technology:
The diamond saw cutting tool that uses comprises diamond disc, diamond gang saw, diamond rope saw etc. now.Diamond rope saw is mainly used in the large-scale mine exploitation, the diamond gang saw is mainly used in the sawing of marble slabs, diamond disc then is widely used in stone material, concrete, the sawing of materials such as pitch, so present municipal road and bridge maintenance and coal gas, running water, in the rescue and relief work operation of electric power and Communication Engineering, all use the diamond disc road pavement, members such as body of wall carry out sawing, but there are some shortcomings in the sawing of diamond disc, can only carry out straight line saw as diamond disc, the original area of a fritter that only need cut is but because saw blade can not carry out the turning sawing, cause and to cut a sheet of area, and because the characteristics of saw blade self, the sawing degree of depth is less than 1/2 of itself diameter, tend to make sawing not settle at one go like this, delayed the time of speedily carrying out rescue work.Diamond chain saw can be cut and degree of depth insertion sawing by the march scroll saw, and both convenient municipal administration maintenance and rescue and relief work operation improve cutting-rate, for a lot of quality time have been won in rescue and relief work.But because chain saw is when the material of strong abrasiveness such as sawing stone material, concrete, the silt particle that produces enters the connecting portion of chain link easily, these silt particles connecting axle that can wear and tear, connecting axle is diminished, connection between the chain link produces loosening, chain is elongated, causes and takes off chain or chain rupture, causes chain saw almost can't be used for the very strong materials of abrasiveness such as sawing stone material, concrete.
Summary of the invention:
Purpose of the present invention is exactly to propose a kind of chain that is used for diamond chain saw, and chain or chain rupture are taken off in difficult generation, can be used for the very strong materials of abrasiveness such as sawing stone material, concrete.
For achieving the above object, a kind of chain that is used for diamond chain saw of the present invention, comprise chain matrix, diamond block, brace and connecting axle, the two ends of each brace are provided with connecting hole, the two ends of each chain matrix are provided with matrix hole, connecting hole by brace is inserted in connecting axle, insert and the affixed matrix hole of the same end of chain matrix up and down at the two ends of connecting axle, the two ends of chain matrix flexibly connect with an end of adjacent brace respectively up and down, diamond block is fixed in up and down on the chain matrix, brace and be provided with the seal washer of connecting axle up and down between the chain matrix.
In a kind of preferred implementation, described chain matrix is provided with the annular groove concentric with matrix hole towards the one side of brace, and described seal washer places in the annular groove, and the chime rings groove contacts with brace.
For ease of chain matrix about the location and installation, the centre of connecting axle can be provided with boss, and the connecting hole of brace is enclosed within on the boss of connecting axle.
As improvement of the present invention, above-mentioned diamond block is fixed on separately the matrix of chain up and down, and the brace at chain matrix two ends is provided with the protection tooth of angle towards diamond block up and down.
The material preferred high strength steel alloy of above-mentioned chain matrix, brace, connecting axle.Seal washer preferred rubber seal washer.
Because the present invention is at brace and be provided with the seal washer of connecting axle up and down between the chain matrix; so; can stop silt particle to infiltrate the connecting hole of brace; connecting axle is shielded; so the present invention is when the very strong material of abrasivenesses such as sawing stone material, concrete; can be not elongated because of the sand wear connecting axle, avoid causing and take off chain or chain rupture.Brace of the present invention can also be provided with the protection tooth of angle towards diamond block, so that in sawing process, diamond block is shielded, and avoids diamond block to collapse the limit, improves sharpness of the present invention.

The specific embodiment:
The CONSTRUCTED SPECIFICATION of the embodiment of the invention is described in detail in detail below in conjunction with accompanying drawing:
Embodiment one:
To shown in Figure 7, the embodiment of the invention one is the chain of band protection tooth as Fig. 1, comprises brace 3, connecting axle 4 and the rubber gasket of chain matrix 1, diamond block 2, band protection tooth 32.Chain matrix 1, brace 3, the material of connecting axle 4 is selected high strength alloy steel for use, diamond block 2 is the alloy powder compacting, soldering, the diamond block that technologies such as plating are made, the two ends of each brace 3 are provided with connecting hole 31, the two ends of each chain matrix 1 are provided with matrix hole 11, the centre of connecting axle 4 is provided with boss 41, the connecting hole 31 of brace 3 is enclosed within on the boss 41 of connecting axle 4, the matrix hole 11 of chain matrix 1 same end is up and down inserted and rivets at the two ends of connecting axle 4, thereby, the two ends of chain matrix 1 flexibly connect by an end of connecting axle 4 and adjacent brace 3 respectively up and down, as Fig. 6, shown in Figure 7, chain matrix 1 is provided with the annular groove 12 concentric with matrix hole 11 towards the one side of brace 3, seal washer 5 places in the annular groove 12, and chime rings groove 12 contacts with brace 3.As shown in Figure 1, diamond block 2 laser weld are on the matrix of chain up and down 1 separately, and protection tooth 32 angles of brace 3 are towards diamond block 2.
Embodiment two:
As shown in Figure 8, the embodiment of the invention two for not with the chain of protection tooth, comprises chain matrix 1, diamond block 2, brace 3, connecting axle 4 and rubber gasket.Diamond block 2 laser weld are on chain matrix 1 about each, and brace 3 is not established the protection tooth.All the other are identical with embodiment one, seldom describe herein.
The material of the embodiment of the invention one, embodiment two is selected high strength alloy steel for use, and is not only wear-resistant but also be difficult for elongation, in addition, and at brace be provided with the seal washer of connecting axle up and down between the chain matrix.Because existing chain saw is when the material of strong abrasiveness such as sawing stone material, concrete, the silt particle of generation enters the connecting portion of chain link easily, these silt particles connecting axle that can wear and tear, connecting axle is diminished, connection between the chain link produces loosening, and chain is elongated, causes and takes off chain or chain rupture.By a large amount of experiments, the present invention stops silt particle to infiltrate by the sealing ring that connecting axle is installed, and connecting axle is shielded, and makes the chain can be not elongated because of the sand erosion connecting axle.If sealing ring is not installed, chain saw almost can't be used for the very strong materials of abrasiveness such as sawing stone material, concrete, even because the sawing time is very short, also can take off chain or chain rupture owing to the sand wear connecting axle causes, sawing can't be gone on.
The present invention is installed on the special-purpose transmission machine, can cut and insert sawing to material march scroll saws such as stone material, concrete, pitches, greatly improves cutting-rate. The present invention is installed in and also can be used for the mining rough stone block on the large-scale saw, its outstanding advantage is that saw can be close to vertical operation and face down and carry out sawing, with adopt diamond rope saw to carry out the horizontal sawing in bottom surface to exploit rough stone block and compare, can optimize the sawing effect, in addition, it is in addition easy to operate, efficient height, the advantage such as the sawing cost is low.
