Description

Technical Field

[0001] The utility model relates to a diamond wire saw with adjustable roller distance, belonging to the technical field of stone cutting. Background Art

[0002] Diamond wire saw refers to a linear cutting tool formed by bonding diamond particles to a steel wire matrix with a binder. It is used to cut hard and brittle materials such as glass, ceramics, silicon, and gemstones. Traditional stone cutting uses saw blades, rope saws, band saws, and other materials with alloy blades for cutting. The alloy blades have a certain thickness, so that traditional tools will form saw seams ranging from 3 to 10 mm when cutting stone. In addition, the carbide tool is in rigid contact with the stone during the processing, which causes large vibrations and easily causes the stone to break during the processing. However, the diamond wire uses flexible contact with the cut stone, and there is no instantaneous impact load. Compared with traditional cutting methods, it has less vibration and noise. In addition, the diamond wire has a small cutting seam, which can reduce the loss of stone during the cutting process.

[0003] At present, diamond wire gang saws use rollers to drive the diamond wire to move and contact the stone surface. The diamonds fixed on the diamond wire rub against the stone and deform to achieve the cutting effect. The rollers are fixed on the roller frame, and the moving roller frame or the moving stone provides the tangential force for the diamond wire to press into the stone. Normally, the distance between the rollers on the roller frame of the diamond wire gang saw cannot be adjusted. When cutting a shorter length of stone, the cutting section of the diamond wire will form a larger bending angle, affecting the stone cutting effect, and in severe cases, affecting the quality of the finished product.

[0004] When the cutting section of the diamond wire forms a large bending angle, it is usually cut using equipment with roller frames spaced closely together, which increases the cutting equipment and equipment footprint. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a diamond wire gang saw with adjustable roller distance, which solves the problem that the roller distance cannot be adjusted and diamond wire gang saw equipment of multiple specifications needs to be set.

[0006] The technical problem to be solved by the utility model is achieved by adopting the following technical solutions: a diamond wire saw with adjustable roller distance, comprising:

[0007] Base, fixed frame, roller frame

[0008] The fixing frame is arranged on the top of the base.

[0009] The roller frame is arranged inside the fixed frame, and the roller frame is divided into a fixed roller frame and a movable roller frame. The fixed roller frame is arranged at one end inside the fixed frame, and the movable roller frame can be fixed inside the fixed frame or slide inside the fixed frame.

[0010] Preferably, a plurality of limiting holes are provided on the side of the fixing frame.

[0011] Preferably, the roller frame is provided with a fixing hole, and the fixing hole can be matched with the limiting hole through a limiting rod to fix the position of the roller frame on the fixing frame.

[0012] Preferably, a moving device is provided on the top of the movable roller frame and the fixed frame.

[0013] Preferably, the moving device includes a guide rail, a rack, a reducer, a drive motor, a transmission rod, and a slider.

[0014] Preferably, the guide rail and the rack are arranged above the fixed frame, and the reducer, the drive motor, the transmission rod and the slide block are arranged above the roller frame.

[0015] Preferably, gears cooperating with the rack are provided at both ends of the transmission rod, and the driving motor drives the transmission rod through the reducer.

[0016] Preferably, the slide block is slidably connected to the guide rail to ensure that the roller frame does not deviate when moving inside the fixed frame.

[0017] The beneficial effects of the utility model are:

[0018] The utility model discloses a diamond wire gang saw with adjustable roller distance, and its main equipment is as follows, including a roller frame, a fixed frame, and a base; wherein the roller frame is divided into a fixed roller frame and a movable roller frame. Two processing rollers are fixedly arranged inside the fixed roller frame and the movable roller frame, and the fixed roller frame is fixed in the fixed frame by bolts, and the tops of the movable roller frame and the fixed frame are provided with a moving device. The fixed roller frame moves on the top of the fixed frame by the moving device, and can adjust the distance between the processing rollers on the fixed roller frame and the processing rollers on the movable roller frame. When the distance between the processing rollers is too long, the diamond wire is arranged on the processing roller, and the length of the diamond wire for cutting the stone is too long. At this time, the diamond wire needs to provide a large downward pressure to ensure the cutting force of the diamond wire. When the cutting force of the diamond wire is insufficient, the cutting effect of the diamond wire is affected. At this time, the movable roller frame is adjusted to control the movable roller frame to be close to the fixed roller frame, so that the cutting force of the diamond wire at the cutting position can be ensured, and the deviation of the diamond wire during cutting can be reduced. Compared with traditional equipment, this design does not require additional diamond wire saws of different specifications, reducing the cutting equipment and the space occupied by the cutting equipment.
