Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a diamond frame saw and method for sawing hard stones with thrust, which can solve the problems of poor stability of the saw blade and serious wear of the saw teeth in the process of sawing ultra-hard stones , which can make the saw frame lift and saw periodically during the reciprocating movement, and then periodically change the relative distance between the saw teeth and the stone, so that the saw frame avoids the reversing point and realizes one-way sawing

Embodiment 1

[0033] This embodiment provides a diamond frame saw for push sawing hard stone, such as figure 1 As shown, it includes a flywheel 1, a crank 2, a connecting rod 3, a saw frame module 5, a first guide mechanism 4, a second guide mechanism 6 and a frame 7. One side of the flywheel 1 is connected to the driving device, and the other side is connected to the crank 2. Described crank 2 links to each other with connecting rod 3. One end of the saw frame module 5 is rotatably connected to the connecting rod 3 , the bottom end of the saw frame module 5 is slidably connected to the frame 7 through the first guide mechanism 4 , and the other bottom end is slidably connected to the frame 7 through the second guide mechanism 6 . Under the action of the driving device, the saw frame module 5 can perform linear reciprocating motion along the frame 7 according to the set track.

[0034] Specifically, one end of the crank 2 is hinged to the center of the flywheel 1, and the flywheel 1 is dri...

Embodiment 2

[0039] The present embodiment also provides a working method of a diamond frame saw for push-sawing hard stone, specifically as follows:

[0040] Such as figure 1 As shown, there is a distance A between the center of the support shaft 42 and the connection point between the connecting rod 3 and the traction lug 54 , and the connecting rod 3 has an included angle α with the negative direction of the x-axis. The positional relationship between sawtooth 53 in different positions and the stone in one period is as follows: Figure 4 As shown, specifically, when the crank 2 rotates counterclockwise relative to the frame 7, that is, when the included angle α is at a positive angle, it drives the connecting rod 3 to move toward the upper left (with the negative direction of x as the left) or the lower left, and the connecting rod 3 drives the saw frame 51 to move synchronously with the first guide mechanism 4.

[0041] The saw frame 51 moves synchronously with the connecting rod 3 u...

Abstract

The invention discloses a diamond frame saw for sawing hard stone in a stroke pushing mode and a method. According to the technical scheme, the diamond frame saw comprises a saw frame module, whereinthe bottom of the saw frame module is slidably connected with a rack, one end of the saw frame module is connected with a crank-link mechanism, and the saw frame module can do reciprocating motion along a set trajectory under the effect of the crank-link mechanism. According to the diamond frame saw for sawing the hard stone in the stroke pushing mode and the method, the problems that in the process of sawing the superhard stone, the stability of a saw blade is poor, and saw teeth are seriously abraded can be solved, a saw frame can be periodically lifted and sawed in the reciprocating motionprocess, then the relative distance between the saw teeth and the stone is periodically changed, the saw frame avoids a reversing point, and one-way sawing is achieved.

Description

technical field [0001] The invention relates to the technical field of stone machinery equipment, in particular to a diamond frame saw and a method for sawing hard stone with thrust. Background technique [0002] Diamond frame saws are mainly used for sawing large-scale natural stone blocks into natural stone slabs of specified thickness at one time. With the vigorous development of home decoration and construction projects, the demand for large slabs is increasing year by year, and diamond frame saws are therefore in the industry. are widely used within. Dozens of saw blades are installed and tensioned on the saw frame of the diamond frame saw. The saw blades are welded with diamond saw teeth, and the saw machine realizes sawing of stone blocks through the saw teeth in reciprocating motion. The sawing motion of the diamond frame saw mainly includes: the horizontal reciprocating motion of the saw frame and the uniform feed motion of the block, in which the horizontal recipr...
