Description
Technical field
The utility model is related to stone slab cutting technique more particularly to a kind of bead string rope tensioning apparatus and rope saws.
Background technology
Saw of restricting is for bulk stone material to be cut into the special equipment of thin plate.Saw of restricting is equipped with multigroup string being mutually parallel
Pearl rope is arranged at intervals with multiple diamond beads on every bead string rope.Bead string rope is sleeved on what is be made of driving wheel and follower
Wheel is fastened, and under the driving of motor, driving wheel drives bead string rope high-speed rotation, suitable when being contacted using diamond bead with stone material
When pressure carries out milling to oversize rock material.In general, 4-79 pieces can be cut simultaneously and can use equipped with 5-80 root bead string ropes on rope saw
Thin slabstone.After thin slabstone is using grinding and cutting processing, the fabulous building board of decorative effect can be obtained.
Due to rope saw on set each bead string rope it is different in size, the sharpness of diamond bead also differs, because
This, needs to be separately provided tensioning apparatus for each bead string rope, each to ensure for bead string rope to be maintained to the state tightened
The step that bead string rope cuts stone material is consistent.Generally, due to the thickness of thin slabstone that needs to cut into is smaller or even meeting
Less than 20mm, therefore, it is necessary to reduce the distance between adjacent beads rope as far as possible, the installation space for resulting in tensioning apparatus extremely has
Limit.
At present, tensioning apparatus usually has two kinds of swing arm and twin shaft guide rail parallel-moving type, wherein, of twin shaft guide rail parallel-moving type
The structure of tight device is complex, and failure rate is higher, is gradually eliminated.And the structure letter of the tensioning apparatus of swing arm
List, cost are relatively low, have obtained very extensive application.
Fig. 1 is the structure diagram of rope saw in the prior art.As shown in Figure 1, rope saw includes：Driving wheel 1, follower
2 and tensioning apparatus, wherein, tensioning apparatus includes：Tensioning wheel 3, swing arm 4, tensioning actuator 5, support hinge shaft 6 and supporting item 7.
Bearing up pulley 3 is laid triangular in shape with driving wheel 1, follower 2, and bead string rope 8 is set in by 3 structure of driving wheel 1, follower 2 and tensioning wheel
Into wheel fasten.One end of swing arm 4 is hinged with tensioning wheel 3, the other end of swing arm 4 as swing arm 4 swing center-side with supporting
Hinge shaft 6 is hinged, and support hinge shaft 6 is connected by hinged block 62 with supporting item 7.The piston rod of tensioning actuator 5 is connected with swing arm 4,
The fixing end of tensioning actuator 5 is connected with supporting item 7, and for driving swing arm 4, around supporting, hinge shaft 6 is upward to be turned tensioning actuator 5
It moves to top pressure bead string rope, so that bead string rope is maintained at the state tightened.
Fig. 2 is the sectional view of tensioning apparatus in Fig. 1, and Fig. 3 is the enlarged view of a-quadrant in Fig. 2.As shown in Figures 2 and 3,
Multiple swing arms 4 are laid side by side, and each swing arm 4 is hinged with a tensioning wheel 3.The swing center-side of each swing arm 4 is all provided with useful
In the connector sleeve 41 for being socketed in 6 outer surface of support hinge shaft, and bearing is equipped between the outer surface of connector sleeve 41 and support hinge shaft 6.
Since the distance between adjacent beads rope is smaller, and each connector sleeve 41 is disposed adjacent, therefore, the axial length of each connector sleeve 41
It is very short so that the rigidity of connector sleeve 41 is poor, easily deforms, and the tension effects for causing tensioning apparatus are poor, and then lead
The vibration for causing bead string rope is more violent, reduces the precision and efficiency of stone material cutting.
