Description

Technical Field

[0001] The invention relates to the technical field of cutting machines, in particular to a diamond wire cutting machine. Background Art

[0002] Diamond wire cutting machine is a high-efficiency and precise cutting tool, mainly used for cutting various hard materials such as wafers, solar panels, jade, luxury stone, marble and granite.

[0003] The diamond wire cutting machine uses a unidirectional or reciprocating motion of the diamond wire to form a relative grinding motion between the diamond wire and the object being cut, thereby achieving the purpose of cutting.

[0004] In order to increase the cutting speed, the prior art has come up with a method of controlling the saw wire to feed in a swinging manner while the saw wire is cutting. That is to say, the saw wire in contact with the workpiece is not fed in a parallel manner, but is deflected in real time. However, in the prior art, to achieve this method, it is necessary to set up an overall lifting frame and a swing frame on the frame, which makes the cutting machine taller and the equipment cost is also higher. Summary of the invention

[0005] In order to overcome the technical defects of the prior art, the present invention provides a diamond wire cutting machine which can achieve fast cutting, has a low equipment height and low cost.

[0006] The technical solution adopted by the present invention is:

[0007] The diamond wire cutting machine comprises a cutting frame, two fixed traction devices, two lifting traction devices, two lifting devices, two rope retracting devices, a saw rope and two buffer devices, wherein the saw rope is sequentially wound around each fixed traction device and the lifting traction device from the outside, and both ends of the saw rope are respectively reeled on the corresponding rope retracting devices, each lifting device is installed on the cutting frame and drives the corresponding lifting traction device to rise and fall, and the two buffer devices are symmetrically installed on the cutting frame, each buffer device is installed in the middle position of the fixed traction device and the lifting traction device on the same side, and each buffer device can be horizontally slidably installed on the cutting frame, and each retracting device can be horizontally slidably installed on the cutting frame. The rope devices are respectively installed at both ends of the top of the cutting machine frame, and each of the lifting and traction devices has a number of independently rotating lifting and traction units, and each of the lifting and traction units has a lifting and traction groove. A staggered pad device is arranged between each of the lifting and traction units, and the staggered pad device includes a staggered roller and two sliding pads. The staggered rollers respectively roll and rub with two adjacent lifting and traction units, and the two sliding pads are transmission-connected to the staggered rollers through connecting rods. Each of the sliding pads is slidably installed on the corresponding lifting and traction unit, and each of the sliding pads slides into the corresponding lifting and traction groove when the staggered roller rotates, and the height of each of the sliding pads is higher than the lifting and traction groove.

[0008] Preferably, operating platforms are provided on both sides of the cutting machine frame, each of the operating platforms is located at the lower side of the corresponding rope-retracting and releasing device, and each of the operating platforms is connected to a staircase.

[0009] Preferably, the fixed traction devices include a fixed traction motor and a fixed traction roller, the fixed traction roller is rotatably mounted on the cutting frame, the fixed traction motor is mounted on the cutting frame and the fixed traction motor is transmission-connected to the corresponding fixed traction roller.

[0010] Preferably, a plurality of fixed traction wheels are mounted on the fixed traction roller.

[0011] Preferably, the lifting and traction device comprises a lifting and traction roller and a plurality of lifting and traction wheels, each of the lifting and traction wheels is mounted on the lifting and traction roller via a flexible ring, so that adjacent lifting and traction wheels rotate independently, and each of the lifting and traction wheels forms a lifting and traction unit.

[0012] Preferably, the lifting device includes a lifting motor and a lifting screw, the lifting motor is installed on the cutting frame, the lifting screw is rotatably installed on the cutting frame, the lifting screw is transmission-connected to the corresponding lifting traction device, and the lifting motor is transmission-connected to the corresponding lifting screw.

[0013] Preferably, the rope retracting and releasing device includes a plurality of retracting and releasing guide rollers, a retracting and releasing motor and a retracting and releasing disk. The retracting and releasing motor is installed on a cutting machine frame. The retracting and releasing disk and each retracting and releasing guide roller can be rotatably installed on the cutting machine frame. The retracting and releasing motor is transmission-connected to the retracting and releasing disk, and the end of the saw rope is arranged on the retracting and releasing disk.

[0014] Preferably, the cache device includes a cache bracket and a cache roller, the cache roller is rotatably mounted on the cache bracket, the cache bracket is mounted on the cutting frame, the cache roller is slidably mounted on the cache bracket, a tensioning cylinder is provided between the cache roller and the cutting frame, and the action direction of the tensioning cylinder causes the cache roller to press toward the saw rope or leave the saw rope.

[0015] The beneficial effects of the present invention are:

[0016] The saw rope is wound around each fixed traction device and the lifting traction device in sequence from the outside, and the two ends of the saw rope are respectively rolled up on the corresponding rope-retracting and releasing devices. One of the two rope-retracting and releasing devices retracts the saw rope, and the other releases the saw rope, thereby realizing repeated use of the saw rope. Each lifting device is installed on the cutting machine frame and drives the corresponding lifting and traction device to rise and fall. When cutting, the two lifting devices rise in sequence, causing the saw ropes on the lower sides of the two lifting and traction devices to swing, which is convenient for quick cutting. It is worth noting that since the heights of the two fixed traction devices remain unchanged, the total height of the entire cutting machine remains unchanged during cutting, thereby reducing the height of the equipment and reducing the production cost. The two buffer devices are symmetrically installed on the cutting frame, and each buffer device has a buffer layer. The storage device is installed in the middle position of the fixed traction device and the lifting and traction device on the same side. Each cache device can be installed on the cutting machine frame in a horizontally slidable manner. Each cache device is used to temporarily store the excess saw rope due to the rising of the lifting device. Each rope collection and release device is installed at both ends of the top of the cutting frame. Each lifting and traction device has a number of independently rotating lifting and traction units. During the entire cutting process, the rope collection speed of the rope collection and release device is greater than the rope release speed of another rope collection and release device. Since the lifting and traction units rotate independently, the lifting and traction units have a certain buffering ability for the relative sliding of the saw rope, thereby reducing the mutual sliding friction between the saw rope and the lifting and traction device and increasing the life of the equipment.

[0017] Each lifting and traction unit has a lifting and traction groove, and a staggered pad device is arranged between each lifting and traction unit. The staggered pad device includes a staggered roller and two sliding pads. The staggered rollers roll and rub with two adjacent lifting and traction units respectively. When one of the lifting and traction devices rises, the buffer device first moves horizontally to temporarily store the excess saw rope, thereby producing a unilateral feeding effect, so that the cutting force of the saw rope on the workpiece is concentrated, thereby enhancing the cutting effect. After the unilateral feeding is completed, during the resetting of the buffer device, the winding speed of the rope-winding and unwinding device responsible for winding is higher than the unwinding speed of the rope-winding and unwinding device responsible for unwinding, so that the saw rope will change its relative position relative to each lifting and traction unit, that is, the saw rope will move along the lifting and traction device. The guide groove slides and frictions, and since the sliding speeds of the saw rope and each lifting and traction groove are different, some have fast relative sliding speeds, and some have slow relative sliding speeds, the adjacent lifting and traction units will produce relative rotation due to the different traction forces of the saw rope, thereby causing the offset roller to rotate. The two sliding pads are connected to the offset roller through a connecting rod, and each sliding pad is slidably installed on the corresponding lifting and traction unit. Each sliding pad slides into the corresponding lifting and traction groove when the offset roller rotates. The height of each sliding pad is higher than the lifting and traction groove. When the offset roller rotates, the offset roller drives the sliding pad to extend into the corresponding lifting and traction groove. Since the sliding pad is made of steel, it cushions the saw rope and plays a role in protecting the lifting and traction groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be further described below in conjunction with the accompanying drawings:

[0031] like Figure 1 — Figure 4As shown, the present embodiment provides a diamond wire cutting machine, including a cutting frame 1, two fixed traction devices 2, two lifting traction devices 3, two lifting devices 4, two rope retracting devices 5, a saw rope and two buffer devices 7. The saw rope is sequentially wound around each fixed traction device 2 and the lifting traction device 3 from the outside, and both ends of the saw rope are respectively wound on the corresponding rope retracting devices 5. One of the two rope retracting devices 5 is used to retract the saw rope, and the other is used to release the saw rope, so that the saw rope can be repeatedly used. Each lifting device 4 is installed on the cutting frame 1 and drives the corresponding lifting traction device 3 to rise and fall. When cutting, the two lifting devices 4 rise in turn, so that the saw ropes on the lower sides of the two lifting traction devices 3 produce a swinging effect. In simple terms, the saw ropes on the lower sides of the two lifting traction devices 3 are alternately raised, which is convenient for quick cutting. It is worth noting that since the heights of the two fixed traction devices 2 remain unchanged, the entire cutting process is performed smoothly during cutting. The total height of the cutting machine remains unchanged, which reduces the height of the equipment and the production cost. The two buffer devices 7 are symmetrically installed on the cutting frame 1, and each buffer device 7 is installed at the middle position of the fixed traction device 2 and the lifting traction device 3 on the same side. Each buffer device 7 can be installed on the cutting frame 1 for horizontal sliding. Each buffer device 7 is used to temporarily store the extra saw rope due to the rising of the lifting device 4. Each rope-retracting device 5 is respectively installed at the two ends of the top of the cutting frame 1. Each lifting traction device 3 has a number of independently rotating lifting traction units. During the entire cutting process, on the whole, the rope-retracting speed of the rope-retracting device 5 is greater than the rope-releasing speed of another rope-retracting device 5, so that the excess saw rope is stored. Since the lifting traction unit rotates independently, the lifting traction unit has a certain buffering ability for the relative sliding of the saw rope, which reduces the mutual sliding friction between the saw rope and the lifting traction device 3 and increases the life of the equipment.

[0032] Each lifting and traction unit has a lifting and traction groove 321, and a staggered pad device 8 is arranged between each lifting and traction unit. The staggered pad device 8 includes a staggered roller 81 and two sliding pads 82. The staggered roller 81 rolls and rubs with two adjacent lifting and traction units respectively. When one of the lifting and traction devices 3 rises, the buffer device 7 first moves horizontally to temporarily store the excess saw rope, thereby producing a unilateral feeding effect, so that the cutting force of the saw rope on the workpiece is concentrated, thereby enhancing the cutting effect. After the unilateral feeding is completed, during the process of the buffer device 7 retracting and resetting, the winding speed of the rope-winding device 5 responsible for winding is higher than the unwinding speed of the rope-winding device 5 responsible for unwinding, so that the saw rope will change its relative position relative to each lifting and traction unit, that is, the saw rope will slide and rub along the lifting and traction groove 321, and Since the sliding speeds of the saw rope and each lifting and traction groove 321 are not the same, some have fast relative sliding speeds and some have slow relative sliding speeds, the adjacent lifting and traction units will produce relative rotation due to the different traction forces of the saw ropes, thereby causing the staggered roller 81 to rotate. The two sliding pads 82 are transmission-connected to the staggered roller 81 through the connecting rod 83, and each sliding pad 82 is slidably installed on the corresponding lifting and traction unit. When the staggered roller 81 rotates, each sliding pad 82 slides into the corresponding lifting and traction groove 321. The height of each sliding pad 82 is higher than the lifting and traction groove 321. When the staggered roller 81 rotates, the staggered roller 81 drives the sliding pad 82 to extend into the corresponding lifting and traction groove 321. Since the sliding pad 82 is made of steel, it cushions the saw rope and plays a role in protecting the lifting and traction groove 321.

[0033] Specifically, operating platforms 11 are provided on both sides of the cutting machine frame 1, and each operating platform 11 is located at the lower side of the corresponding rope-retracting and releasing device 5. Each operating platform 11 is connected to a staircase 12 for easy maintenance.

[0034] Specifically, the fixed traction device 2 includes a fixed traction motor 21 and a fixed traction roller 22. The fixed traction roller 22 is rotatably installed on the cutting frame 1. The fixed traction motor 21 is installed on the cutting frame 1 and the fixed traction motor 21 is transmission-connected to the corresponding fixed traction roller 22, thereby realizing the traction of the saw rope.

[0035] Specifically, a plurality of fixed traction wheels are mounted on the fixed traction roller 22. Similar to the structure of the lifting traction unit, each fixed traction wheel can also rotate independently. Both the lifting traction unit and the fixed traction wheel adopt the flexible ring 322 mentioned below to realize such independent rotation.

[0036] Specifically, the lifting and traction device 3 includes a lifting and traction roller 31 and a plurality of lifting and traction wheels 32. Each lifting and traction wheel 32 is installed on the lifting and traction roller 31 through a flexible ring 322. The flexible ring 322 is made of silicone, so that each lifting and traction wheel 32 can rotate relative to the lifting and traction roller 31 and can realize transmission. Silicone has been widely used in the field of flexible couplings similar to the present application and will not be repeated here. Adjacent lifting and traction wheels 32 can rotate independently. The independent rotation mentioned here and above refers to the lifting and traction wheels 32 relative to the lifting and traction roller 31, and the fixed traction roller 22 relative to the fixed traction wheel. Both can cause relative rotation under the action of the flexible ring 322. Each lifting and traction wheel 32 forms a lifting and traction unit. When cutting, each lifting and traction roller 31 pulls the saw rope buffer device 7 to slowly collect excess saw rope. After cutting, the buffer device 7 retracts. Due to the action of the flexible ring 322, the mutual friction between the saw rope and the lifting and traction roller 31 is reduced, thereby increasing the service life.

[0037] Specifically, the lifting device 4 includes a lifting motor and a lifting screw. The lifting motor is installed on the cutting frame 1. The lifting screw is rotatably installed on the cutting frame 1. The lifting screw is transmission-connected to the corresponding lifting traction device 3. The lifting motor is transmission-connected to the corresponding lifting screw, thereby pulling the corresponding lifting traction device 3 to lift and lower.

[0038] Specifically, the rope retracting device 5 includes a plurality of retracting guide rollers, a retracting motor and a retracting disk. The retracting motor is mounted on the cutting machine frame 1. The retracting disk and each retracting guide roller can be rotatably mounted on the cutting machine frame 1. The retracting motor and the retracting disk are transmission-connected. The end of the saw rope is arranged on the retracting disk. The retracting disk is used to retract the saw rope. Each retracting guide roller is used to provide guidance for the saw rope.

[0039] Specifically, the cache device 7 includes a cache bracket 71 and a cache roller 72. The cache roller 72 is rotatably mounted on the cache bracket 71, and the cache bracket 71 is mounted on the cutting frame 1. The cache roller 72 is horizontally slidably mounted on the cache bracket 71. The specific implementation method is that the cache bracket 71 has a long groove, and the adaptation between the long groove and the cache roller 72 realizes that the cache roller 72 can be rotatably mounted on the cache bracket 71 and slidably mounted on the cache bracket 71, thereby realizing the above-mentioned "each cache device 7 can be horizontally slidably mounted on the cutting frame 1", and a tensioning cylinder is provided between the cache roller 72 and the cutting frame 1, and the output end of the tensioning cylinder is inserted into a preset hole position at the end of the cache roller 72, so that the action direction of the tensioning cylinder makes the cache roller 72 press against the saw rope or leave the saw rope, thereby storing excess saw rope when the lifting and traction device 3 rises, and retracts after the feeding is completed, so as to facilitate the recovery of excess saw rope.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
