Frame saw for cutting granite through diamond bits or diamond segments

The invention relates to a frame saw for sawing granite through a diamond tool bit, and belongs to machinery of stone material machining. The frame saw for sawing the granite through the diamond tool bit or frame saw diamond segments comprises a workbench and a saw frame, wherein the two sides of the workbench are respectively provided with a support, and a lifting table is arranged in the middle of the workbench. The frame saw for sawing the granite through the diamond tool bit is characterized in that the two ends of the saw frame are connected to the lower ends of swing arms through lower suspension shafts respectively, the upper end of each swing arm is connected to a machine frame through an upper suspension shaft, the distance between the two upper suspension shafts on the swing arms and the distance between the two lower suspension shafts are unequal, and one end of the saw frame is connected with a power mechanism used for pushing the saw frame to swing back and forth. The frame saw for sawing the granite through the diamond tool bit has the advantages that due to the fact that a saw blade and a stone material sawing face are in point contact, large enough sawing pressure can be exerted on stone materials; due to the facts that the saw blade swings up and down and the sawing bottom face is an approximate circular arc surface, cooling water can easily enter the sawing face to cool the tool bit and take away stone powder, sawing lubrication conditions are improved, the service life of the tool bit is prolonged, accordingly, a failure rate is reduced greatly, and repair and maintenance cost is reduced.

One kind of granite cutting with a diamond blade saw frame

 

[0001] Technical Field

 

The present invention relates to a diamond saw blade cutting granite frame. Is a stone processing machinery.

 

BACKGROUND

 

[0002] Currently, the diamond frame saw is marble, limestone and other soft stone and major equipment containing large amounts of low quartz plate processing, and dozens of root saw blade arranged in box, complete stone box saw reciprocating linear motion through cutting. Because diamond frame saw with high processing efficiency, cutting speed, surface quality and processing wool board, integrated low cost, and highly favored by stone processing, and for containing high amounts of quartz granite cutting due because granite hard, stone blade with full contact blade for stone cutting small pressure unit, which can not be enough pressure to complete the granite cutting. Therefore, the traditional diamond frame saw only the processing of marble, granite can not be processed.

 

[0003] SUMMARY OF THE INVENTION

 

In order to compensate for the lack of the prior art, the present invention provides a unit cutting diamond blade cutting pressure Dayong granite frame saws

 

A granite sawing with a diamond blade saw frame, including the table and saw frame, the sides are respectively provided with a table frame, with the middle of the lift table, characterized in that: the saw the distance between the suspension axis between the two and the two ends of the hanging frame's suspension axis, respectively connected to the lower end of the lower shaft by the arm, the upper arm are connected through a shaft suspended in the frame, and the swing arm The distance is not equal to one end of the saw frame is also connected to promote its momentum swinging back and forth agency.

 

[0004] This invention is directed to the shortcomings of the prior art and by the arm at both sides of the saw frame, so that the saw frame swing trajectory by changing the saw frame, so that when the tip of the blade on the cutting blade cutting sequentially participate , and then cooling is achieved from the cutting chip removal, cutting slits formed in the bottom surface of which is approximately circular surface, enabling the blade is always in point contact with the stone, greater pressure to ensure the cutting unit to apply a granite processing.

 

[0005] In order to make the entire trip in a row saw blade cutting, saving space and cost savings, the swing arm suspension axis distance between the two is less than twice the distance between the axes hanging.

 

[0006] In order to save the cost of renovation, the power mechanism includes a flywheel driven by the main motor crank and connecting rod mechanism.

 

[0007] The present invention compared with conventional diamond saw frame, has the following significant advantages: ① Since the cutting blade and the stone surface is a point contact, so the head is large enough to give the stone cutting pressure increase while the cutting resistance be in the linear translation of formula 1/3 to 1/5. ② Because of the tilting blade was run, and the bottom surface of the slit is approximately circular surface, therefore, is conducive to the cooling surface of the cooling water into the head and cutting away the powder, improved cutting, lubrication, improved blade life. ③ cutting motion mechanism of the swing mechanism, so the failure rate will be greatly reduced, lower repair and maintenance costs. ④ use different diamond segments can be used to cut granite and marble and other stone.

Embodiment

 

[0009] In order to clearly illustrate features of the present technical solution, the following by one and combined with its accompanying drawings, the scheme described, this embodiment includes a saw frame 4 and the table 6, both sides of the table 6 are provided A bracket 8 is provided with lifting table 6 central station 7, characterized in that: the saw frame 4 are respectively the ends of the suspension arm 3 is connected to the lower end of the shaft 2, the upper arm 2 through a respective through I hung shaft connected to the rack 8, and two hanging on the arm 2-axis distance between the I and the two lower suspension shaft distance between unequal, preferably on the suspension arm 2 on both axis I of is smaller than the distance between the two distance between the suspension axis, the saw frame 4 is also connected to one end of a driving force mechanism which oscillates the power mechanism includes a flywheel 11 driven by the main motor 12 and the crank rod 10.

 

[0010] As can be seen from the figure, the saw frame 4 is suspended by the arm 2 on the holder 8. Two hanging axis distance between A and B I from the suspension axis between the two are not equal, the stone cutting blade kerf bottom surface approximately circular arc surface. By changing the A, B from the magnitude of the difference can change the radius of curvature of the cutting path. A, B, the difference in distance increases, the smaller the radius of curvature of the trajectory is formed.

 

[0011] The main motor 10 drives the flywheel 11 is rotated by a belt drive, a flywheel 11 driven by the crank 12, connecting rod 9 to pull the saw reciprocating swing frame 4, 5 in order to achieve the cutting blade granite.

 

[0012] 7 lifts 8 in four columns in the middle, along the lift bracket 8, 6 and stone bench driven feed.
