Description

Technical Field

[0001] The present invention relates to the technical field of multi-wire cutting machines, and in particular to a flexible direction-changing multi-wire cutting machine. Background Art

[0002] In the field of material processing, especially in the cutting of sapphire materials, multi-wire sawing machines play an important role. Multi-wire sawing machines use the high-speed reciprocating motion of diamond wires with diamond particles to cut the sapphire materials in the processing area. It has many advantages, such as the ability to change large materials into small ones, and has the advantages of high production efficiency, high product quality, low processing cost, high control accuracy and green environmental protection.

[0003] However, as the requirements for cutting technology in industrial production continue to increase, the existing multi-wire cutting machines have gradually exposed some shortcomings in terms of material positioning and cutting flexibility, making it difficult to fully meet more refined and diversified production needs.

[0004] During the material positioning process, the fixture in the prior art cannot adapt well to the irregular surface of the material, resulting in inaccurate and unstable positioning. During the cutting operation, the movement and direction of the material are not flexible enough, which limits the diversity of cutting methods. Based on this, the present invention provides a flexible direction-changing multi-wire cutting machine, which aims to solve the problems existing in the above-mentioned prior art. The multi-wire cutting machine is used to cut sapphire materials. It uses the high-speed reciprocating motion of the diamond wire with diamond particles to cut the sapphire material in the processing area, thereby changing the large material into small material. Summary of the invention

[0005] In order to solve the problems mentioned in the above background technology, the present invention provides a flexible direction-changing multi-wire cutting machine.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A flexible and changeable multi-wire cutting machine comprises a cutting machine chassis, a pick-up and release port is provided on one side of the cutting machine chassis, and a door panel is installed at the pick-up and release port position; a material storage table is slidably installed inside the cutting machine chassis through a first slide rail; a material positioning mechanism is provided on the top of the material storage table; the extension direction of the first slide rail is toward the pick-up and release port, and the material storage table is pushed to move on the first slide rail by a first hydraulic cylinder; the material storage table is driven to rotate and rise and fall by a driving mechanism; and a wire cutting mechanism is installed in the cutting machine chassis.

[0007] Preferably, the material positioning mechanism includes a pair of mounting brackets, on which a plurality of positioning columns are horizontally movably mounted, and the material is clamped and positioned by the positioning columns. A second slide rail is mounted on the material storage table, and the mounting bracket is mounted on the second slide rail. A second hydraulic cylinder is mounted on the top of the material storage table, which is located on the side away from the two mounting brackets, and the output shaft of the second hydraulic cylinder is fixed to the mounting bracket.

[0008] Preferably, a positioning ball is fixed to one end of the positioning column where the two mounting brackets are close to each other, and a pushing member is fixed to the other end of the positioning column.

[0009] Preferably, a push plate is provided on the side of the two mounting brackets away from each other, and a horizontal driving mechanism is provided between the push plate and the mounting bracket, and the push plate is driven to move horizontally by the horizontal driving mechanism. A positioning column locking mechanism is also installed on the mounting bracket.

[0010] Preferably, the horizontal driving mechanism comprises a plurality of threaded rods, which are rotatably mounted on one side of the mounting bracket, and a plurality of threaded sleeves are fixed on the pushing plate, which are mounted one by one on the outside of the threaded rods.

[0011] Preferably, a first gear is fixed to the outside of the threaded rod, a gear ring is rotatably mounted on the mounting bracket, inner and outer rings of the gear ring are provided with meshing teeth, and the plurality of first gears are meshed with the inner ring of the gear ring.

[0012] Preferably, a rotating motor is also fixed on the mounting bracket, a second gear is fixed to the output shaft of the rotating motor, and the second gear is meshed with the outer ring of the gear ring.

[0013] Preferably, the positioning column locking mechanism includes a first rotating bracket and a second rotating bracket, the first rotating bracket and the second rotating bracket are both rotatably mounted on a horizontal rod, the horizontal rod is fixed on the mounting bracket, the first rotating bracket and the second rotating bracket are provided with a plurality of branches, clamping members are fixed on the branches, the clamping members on the first rotating bracket and the second rotating bracket match each other, and when the first rotating bracket and the second rotating bracket rotate in opposite directions, they can clamp and release the positioning column.

[0014] Preferably, guide plates are fixed on the sides of the first rotating bracket and the second rotating bracket that are away from each other, and guide grooves are provided on the guide plates. The guide grooves extend along the spiral. The spiral directions of the two guide grooves are opposite, and the centers of the spirals are located on the rotation centers of the first rotating bracket and the second rotating bracket. A third hydraulic cylinder is also installed on the mounting bracket, and two connecting rods are fixed on the output shaft of the third hydraulic cylinder. Limiting rods are fixed on the connecting rods, and the two limiting rods extend into the two guide grooves respectively.

[0015] Preferably, an arc-shaped clamping groove is provided on the clamping piece, and raised particles are provided in the arc-shaped clamping groove, and an anti-slip texture is provided on the outside of the positioning column. When the clamping pieces connected to the first rotating bracket and the second rotating bracket are close to each other, the positioning column can be clamped in the middle. The combination of the raised particles and the anti-slip texture can increase the friction force and prevent the positioning column from continuing to move horizontally.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The flexible reversible multi-wire cutting machine of the present invention has a unique material storage table moving mechanism arranged inside the cutting machine chassis. The material storage table is connected to the inside of the cutting machine chassis through a first slide rail, and can be pushed by a first hydraulic cylinder to move linearly on the first slide rail. At the same time, the material storage table can also realize rotation and lifting movement with the help of a driving mechanism. This combination of multi-dimensional movement methods enables the material to be cut placed on the material storage table to realize flexible direction change during the cutting process. When faced with sapphire materials of different shapes, sizes and cutting requirements, the position and angle of the material can be accurately adjusted according to the actual cutting path planning, and it is no longer limited to the relatively single material movement method of the traditional cutting machine, which greatly improves the flexibility of the cutting operation, can better meet the diverse cutting needs, and bring more convenience and possibilities to the production process.

[0017] 2. Through the design of the material positioning mechanism, the positioning mechanism includes a pair of mounting brackets, on which multiple positioning columns are horizontally mounted. After the sapphire material is placed on the material storage table, the two mounting brackets can be driven to approach each other by controlling the extension of the second hydraulic cylinder. In this process, the positioning columns will contact both sides of the material. Since the positioning columns are movably mounted on the mounting brackets, in the process of clamping the material, each positioning column can automatically adjust its position according to the irregular shapes of the surfaces on both sides of the material, so as to achieve a close fit with the irregular surfaces on both sides of the material. This adaptive fitting method can ensure that the contact between the positioning column and the material is more sufficient and uniform, laying a good foundation for subsequent precise cutting, and effectively avoiding the problem of cutting deviation caused by inaccurate positioning.

[0018] 3. After each positioning column is automatically adjusted into place by the thrust, the positioning column locking mechanism can quickly lock the position of the positioning column. The positioning column locking mechanism is composed of a first rotating bracket, a second rotating bracket and other components. When the first rotating bracket and the second rotating bracket rotate in opposite directions, the positioning column can be firmly clamped. In addition, an arc-shaped clamping groove is provided on the clamping piece, and raised particles are provided in the groove, while the outside of the positioning column is provided with an anti-slip texture. The combination of the two can significantly increase the friction force and further prevent the positioning column from continuing to move horizontally. During the entire process of material processing, even if it is subjected to external force, the material will not be displaced due to the loosening of the positioning column, thereby ensuring the accuracy of cutting and helping to produce higher quality products.

[0019] 4. A push plate is set on the side where the two mounting brackets are away from each other, and the push plate is driven to move horizontally by a horizontal drive mechanism. Before material processing, the push plate is driven away from the positioning column by the horizontal drive mechanism, which can leave enough space for the positioning column to automatically adjust its position and ensure that the positioning column can smoothly make adaptive adjustments according to the shape of the material. After the material processing is completed, the horizontal drive mechanism can push the push plate close to the positioning column. After the push plate contacts the push piece on the positioning column, it can push the push piece to move and reset, so that the entire equipment can be quickly restored to a state where it can be used again. This flexible push plate operation mechanism greatly improves the efficiency of equipment use, reduces the time for equipment adjustment and preparation, and provides a strong guarantee for continuous production operations.

[0020] 5. The design of the locking mechanism of the positioning column not only ensures the stability of the locking of the positioning column, but also performs well in terms of operational convenience. The clamping and loosening operations of the clamps on both sides of the positioning column can be realized by controlling the extension and retraction of the third hydraulic cylinder. Specifically, when the third hydraulic cylinder is controlled to extend, the limit rods on the two connecting rods fixed to its output shaft will move along the guide grooves on the guide plate. Since the guide grooves extend along the spiral and the spiral directions of the two guide grooves are opposite, this can drive the second rotating bracket to rotate clockwise relative to the horizontal rod, and at the same time drive the first rotating bracket to rotate counterclockwise relative to the horizontal rod, thereby separating the clamps on both sides of the positioning column and loosening the positioning column; conversely, when the third hydraulic cylinder is controlled to shorten, the clamps on both sides of the positioning column can be driven close to the clamping positioning column. This simple and efficient operation method enables operators to quickly and accurately lock and unlock the positioning column, further improving the overall operational convenience and work efficiency of the equipment.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example 1 Reference Figure 1-5 A flexible and changeable multi-wire cutting machine comprises a cutting machine chassis 1, a pick-up and release port is provided on one side of the cutting machine chassis 1, and a door panel 101 is installed at the pick-up and release port position, a material storage table 3 is slidably installed inside the cutting machine chassis 1 through a first slide rail 102, a material positioning mechanism 4 is provided on the top of the material storage table 3, the extension direction of the first slide rail 102 is toward the pick-up and release port, and the material storage table 3 is pushed to move on the first slide rail 102 by a first hydraulic cylinder 103, and the material storage table 3 is driven to rotate and rise and fall by a driving mechanism, and a wire cutting mechanism 2 is installed in the cutting machine chassis 1; The sapphire material to be cut is placed on the material storage table 3, the material is positioned by the material positioning mechanism 4, and then the material storage table 3 is driven by the first hydraulic cylinder 103 to move to the bottom of the wire cutting mechanism 2, and the material is cut by the wire cutting mechanism 2. Since the material storage table 3 is driven to rotate and rise and fall by the driving mechanism, and the movement of the material storage table 3 by the first hydraulic cylinder 103 is coordinated, the movement of the material can be flexibly changed, and the material can be cut according to actual needs, which is more convenient to use.

[0025] Example 2 Reference Figure 1-10The difference between this embodiment and embodiment 1 is that the material positioning mechanism 4 includes a pair of mounting brackets 401, and a plurality of positioning columns 5 are horizontally and movably mounted on the mounting brackets 401, and the material is clamped and positioned by the positioning columns 5. A second slide rail is mounted on the material storage table 3, and the mounting bracket 401 is mounted on the second slide rail. The top of the material storage table 3 is located on the side away from the two mounting brackets 401 and is equipped with a second hydraulic cylinder 403, and the output shaft of the second hydraulic cylinder 403 is fixed to the mounting bracket 401; After placing the sapphire material on the material storage table 3, the two mounting brackets 401 can be driven to approach each other by controlling the extension of the second hydraulic cylinder 403. During the process of the positioning columns 5 approaching each other, they will contact with both sides of the material. Since the positioning columns 5 are movably installed on the mounting brackets 401, during the clamping process, each positioning column 5 will automatically adjust its position so that the positioning columns 5 and the irregular surfaces on both sides of the material fit each other. A positioning ball 501 is fixed to one end of the positioning column 5 where the two mounting brackets 401 are close to each other, and a pushing member 502 is fixed to the other end of the positioning column 5. During the clamping process, the positioning ball 501 contacts with the side of the material.

[0026] Example 3 Reference Figure 1-10 The difference between this embodiment and embodiment 2 is that a push plate 6 is provided on the side of the two mounting brackets 401 away from each other, a horizontal driving mechanism is provided between the push plate 6 and the mounting bracket 401, and the push plate 6 is driven to move horizontally by the horizontal driving mechanism, and a positioning column locking mechanism 7 is also installed on the mounting bracket 401; When each positioning column 5 is automatically adjusted to a position by the thrust, the position of the positioning column 5 is locked by the positioning column locking mechanism 7, and the material can be stably positioned at this time. Since the position of each positioning column 5 can be automatically adjusted, the positioning of the material is more stable, and the material will not be displaced due to external force during the processing, thereby improving the cutting accuracy and the product quality is higher; Before material processing, the pushing plate 6 is driven away from the positioning column 5 by the horizontal driving mechanism, leaving enough space for the positioning column 5 to automatically adjust. After the material processing is completed, the pushing plate 6 is pushed close to the positioning column 5 by the horizontal driving mechanism, and the pushing plate 6 contacts the pushing member 502, pushing the pushing member 502 to move and reset, so that it can be used next time.

[0027] Example 4 Reference Figure 1-10 The difference between this embodiment and embodiment 3 is that the horizontal driving mechanism includes a plurality of threaded rods 602, the threaded rods 602 are rotatably mounted on one side of the mounting bracket 401, a plurality of threaded sleeves 601 are fixed on the pushing plate 6, and the plurality of threaded sleeves 601 are mounted on the outside of the threaded rods 602 in a one-to-one correspondence; A first gear 603 is fixed to the outside of the threaded rod 602, and a gear ring 604 is rotatably mounted on the mounting bracket 401. The inner and outer rings of the gear ring 604 are provided with meshing teeth, and the plurality of first gears 603 are meshed with the inner ring of the gear ring 604; In order to drive the pushing plate 6 to move horizontally, when the gear ring 604 rotates, it can drive the multiple first gears 603 to rotate synchronously, and then drive the multiple threaded rods 602 to rotate synchronously. Due to the threaded cooperation between the threaded sleeve 601 and the threaded rod 602, the pushing plate 6 can be driven to move horizontally.

[0028] In order to drive the gear ring 604 to rotate, a rotating motor 605 is also fixed on the mounting bracket 401. The output shaft of the rotating motor 605 is fixed with a second gear 606. The second gear 606 is meshed with the outer ring of the gear ring 604. When the rotating motor 605 is turned on, the second gear 606 can be driven to rotate. Since the second gear 606 is meshed with the outer ring of the gear ring 604, the gear ring 604 can be driven to rotate, thereby driving the push plate 6 to move horizontally. The direction of movement depends on the direction of the output shaft of the rotating motor 605.

[0029] Example 5 Reference Figure 1-16 , the difference between this embodiment and embodiment 2 is that the positioning column locking mechanism 7 includes a first rotating bracket 701 and a second rotating bracket 702, the first rotating bracket 701 and the second rotating bracket 702 are both rotatably mounted on a horizontal rod 703, the horizontal rod 703 is fixed on the mounting bracket 401, the first rotating bracket 701 and the second rotating bracket 702 are provided with a plurality of branches 704, and clamping members 705 are fixed on the branches 704. The clamping members 705 on the first rotating bracket 701 and the second rotating bracket 702 match each other, and when the first rotating bracket 701 and the second rotating bracket 702 rotate in opposite directions, they can clamp and release the positioning column 5; Multiple branches 704 are distributed in an array around the horizontal rod 703, and the distribution positions of the positioning columns 5 correspond to the distribution positions of the clamping members 705. Both sides of each positioning column 5 are provided with a clamping member 705 on the first rotating bracket 701 and a clamping member 705 on the second rotating bracket 702, respectively, to ensure that each positioning column 5 can be positioned by clamping.

[0030] A guide plate 709 is fixed to the side of the first rotating bracket 701 and the second rotating bracket 702 which are away from each other. A guide groove 7091 is provided on the guide plate 709. The guide groove 7091 extends along the spiral. The spiral directions of the two guide grooves 7091 are opposite, and the center of the spiral is located at the rotation center of the first rotating bracket 701 and the second rotating bracket 702. A third hydraulic cylinder 706 is also installed on the mounting bracket 401. Two connecting rods 707 are fixed to the output shaft of the third hydraulic cylinder 706. The connecting rods 707 are fixed with limit rods 708. The two limit rods 708 extend into the two guide grooves 7091 respectively. Reference Figure 13-15 In order to conveniently and quickly clamp and release the positioning column 5, it is only necessary to control the third hydraulic cylinder 706 to extend, so as to drive the limiting rod 708 to move along the guide groove 7091. Due to the shape design of the guide groove 7091, it can drive the second rotating bracket 702 to rotate clockwise relative to the horizontal rod 703, and drive the first rotating bracket 701 to rotate counterclockwise relative to the horizontal rod 703, thereby driving the clamping parts 705 on both sides of the positioning column 5 to separate. Conversely, when the third hydraulic cylinder 706 is controlled to shorten, the clamping parts 705 on both sides of the positioning column 5 can be driven to approach the clamping positioning column 5.

[0031] Among them, an arc-shaped clamping groove is formed on the clamping piece 705, and a raised particle 7051 is provided in the arc-shaped clamping groove. The outside of the positioning column 5 is provided with an anti-slip texture 503. When the clamping piece 705 connected to the first rotating bracket 701 and the second rotating bracket 702 are close to each other, the positioning column 5 can be clamped in the middle. The cooperation between the raised particle 7051 and the anti-slip texture 503 can increase the friction force and prevent the positioning column 5 from continuing to move horizontally.
